  However, since the former prior art has a structure in which the nozzle spout is always open, there is a possibility that the medicine remaining in the nozzle leaks outside when it is carried as it is.

  On the other hand, the latter prior art is provided with a plug part that seals the nozzle spout on the back surface of the overcap as a countermeasure against leakage. However, in the state where the overcap is removed, the residual material still remains. The leak has not been solved.

  Moreover, such conventional dispensers may irritate the nose because the pressurized medication is sprayed directly into the nostrils. Since this leads to user discomfort, there is room for improvement.

  The problem to be solved by the present invention is that, even when the overcap is removed, the residue in the nozzle does not leak and allows a natural pouring operation, and the nozzle is inserted into a cavity such as a nostril. It is to propose a dispenser that can reduce the burden on the cavity when liquid content is poured out.

The dispenser of the present invention includes a container body having a mouth portion that is filled with a liquid content, a foam pump that is suspended and held in the mouth portion of the container body, and an opening portion that penetrates the stem of the foam pump. A cap that is fixed to the mouth of the container body, and a taper that is connected to the stem penetrating the cap and repeatedly pours out the contents of the container body in the form of bubbles by repeated approach and separation from the container body. The nozzle has a shoulder portion that contacts the upper end of the stem, an inner cylinder portion mounted on the stem, an elastic member placed on the shoulder portion of the inner cylinder portion, An outer cylinder part that has an abutting surface that contacts the upper end of the elastic member and can be moved toward and away from the shoulder part, and a tip part that extends toward the outer cylinder part, and is fixed inside the inner cylinder part and a shaft portion that is, the shaft portion of the outer tube portion with the inner cylindrical portion Together are arranged on the side, the tip portion of the shaft portion than the base of the shaft portion becomes a distal enlarged portion of the large diameter, the outer cylinder and the shoulder portion of the inner cylinder part by the biasing force of the elastic member The inner surface of the outer cylinder part is sealed while contacting the seating surface formed on the outer cylinder part in a state where the contact surface of the part is separated from the inner surface , while the inner surface is resisted against the urging force of the elastic member. A back surface that forms an annular spout with the outer cylinder portion apart from a seating surface formed on the outer cylinder portion in a state where the shoulder portion of the cylinder portion and the contact surface of the outer cylinder portion are brought close to each other. It is characterized by having.

According to the present invention, the back surface is in contact with a step portion formed on the inner side of the outer cylinder portion in a state where the shoulder portion of the inner cylinder portion and the contact surface of the outer cylinder portion are separated from each other. In the state where the shoulder part of the inner cylinder part and the contact surface of the outer cylinder part are separated from each other, the front edge of the outer cylinder part is brought into contact as a seating surface. You can also. Furthermore, it is preferable that the said back surface becomes an inclined surface which guides the content poured out from the said spout outlet diagonally forward with the said seat surface .

  Furthermore, in the present invention, the stem is integrally provided with a stopper on the outside thereof for restricting movement of the outer cylinder portion due to the approach of the shoulder portion of the inner cylinder portion and the contact surface of the outer cylinder portion. It is preferable.

  Furthermore, in the present invention, the opening of the cap has a shape that allows the nozzle and the container main body to approach and separate from each other, and has a notch connected to the opening, and the outer cylinder portion of the nozzle is And a protrusion that allows the container body to approach and move away from the container body on the outside, and the protrusion rotates the container body or the nozzle around an axis to When the nozzle and the container main body are brought close to each other by shifting the position, it is preferable that a contact portion that contacts the cap and regulates the approach between the nozzle and the container main body is preferable.

  In addition, the present invention is preferably used as a nasal administration device used for administering nasal drops to the nostrils.

According to the present invention, if the nozzle and the container main body are not approached and separated from each other, the relationship between the inner cylinder part and the outer cylinder part is determined by the contact between the shoulder part of the inner cylinder part and the outer cylinder part by the urging force of the elastic member. A state in which the overcap is removed because the enlarged portion of the shaft portion is in contact with the seating surface formed on the outer tube portion and seals the inside of the outer tube portion while being kept away from the contact surface However, the residue in the nozzle will not leak.

On the other hand, in the present invention, if the nozzle and the container main body are approached and separated from each other to operate the foam pump to pour out the contents, the above-mentioned inner cylindrical portion is resisted against the urging force of the elastic member. The shoulder portion and the abutting surface of the outer cylinder portion are brought close to each other, and the enlarged portion of the shaft portion is separated from the seating surface formed on the outer cylinder portion, and the outer cylinder portion is placed at the tip of the outer cylinder portion. Since an annular spout is formed together with the cylindrical portion, a natural spout operation can be performed without stopping the approach and separation of the nozzle and the container body.

  Moreover, according to the present invention, since the mechanism for pumping the liquid content to the nozzle is a foam pump, the liquid content to be poured out by inserting the nozzle into a cavity such as a nostril is a bubble containing air. Therefore, it is possible to reduce the burden on the inner wall of the cavity when the nozzle is inserted into the cavity and the contents are poured out.

In addition, according to the present invention, when the nozzle and the container main body are moved closer and farther to operate the foam pump to pour out the contents, the tip enlarged portion of the shaft portion is formed in the outer cylinder portion . In order to form an annular spout with the outer cylinder part apart from the seating surface, while reducing the burden on the cavity part when inserting the nozzle into the cavity part such as a nostril to pour out the contents, The contents can be poured evenly over the entire inner wall of the cavity.

In the present invention, the back surface protrudes from the front end of the outer tube portion, and in the state where the shoulder portion of the inner tube portion and the contact surface of the outer tube portion are separated from each other, the front edge of the outer tube portion If the part contacts as a seating surface , the nozzle spout can be completely sealed, and even when there is no overcap, it is possible to prevent dust from entering from the tip of the nozzle to the inside so that the inside of the nozzle is always clean. Can keep.

In the present invention, when the back surface is an inclined surface that guides the contents poured out from the spout outlet obliquely forward together with the seat surface , the contents are poured out by inserting a nozzle into a cavity such as a nostril. In order to reduce the burden on the hollow part at the time, and to uniformly discharge the contents to the entire inner wall of the cavity part, it is possible to focus the contents on the inner wall near the nozzle tip. it can.

  In the present invention, when the foam pump is operated to dispense the contents, the shoulder portion of the inner cylinder portion and the contact surface of the outer cylinder portion are brought close to each other against the biasing force of the elastic member. The distance between these can be regulated by bringing the shoulder portion of the inner cylinder portion and the outer cylinder portion into contact with each other. However, as in the present invention, the stem is disposed outside the inner tube portion. If a stopper that restricts the movement of the outer cylinder part due to the approach of the shoulder part of the cylinder part and the contact surface of the outer cylinder part is provided integrally, a stopper is provided on the outside of the stem. With a simple method, the interval (play) between the inner cylinder part and the outer cylinder part can be easily changed according to the user and application.

  Furthermore, in the present invention, the opening of the cap has a shape that allows the nozzle and the container main body to approach and separate from each other, and has a notch connected to the opening. And a protrusion that allows the container body to approach and move away from the container body on the outside, and the protrusion rotates the container body or the nozzle around an axis to When the nozzle and the container body are moved closer to each other by shifting the position of the nozzle, the operation of the foam pump is caused by providing a contact portion that contacts the cap and restricts the approach between the nozzle and the container body. The movement of the nozzle and the container body to be controlled can be regulated by the relationship between the nozzle and the opening of the cap, that is, the container body or the nozzle is simply operated by simply rotating the nozzle around the axis. To cover the bar cap, without increasing the size of the overcap to be separately prepared, it may be to prevent erroneous injection.

  The dispenser of the present invention can exert its effect remarkably by using it as a nasal medication dispenser used to administer nasal sprays to the nostrils.

  Further, the air piston 127 has a seal end portion 127d that is slidably held on an inner surface of a stem (jet ring) 129 attached to the piston guide 125, and is formed between the outer surface of the piston guide 125. The formed gap is communicated with the upper position of the ball 126 through a gap formed between the piston guide 125 and the stem 129. The stem 129 houses two mesh rings Rm on which meshes are stretched.

  As shown in FIG. 1, reference numeral 140 is connected to a stem 129 that passes through the opening 131 of the cap 130, and the stem 129 is repeatedly pressed by pushing the container body 110 in the d1 direction and returning to the d2 direction shown in FIG. It is a tapered nozzle that pours out foamy medicine that has been pumped through.

  In FIG. 4, reference numeral 141 denotes an inner cylinder portion (hereinafter referred to as “nozzle inner cylinder portion”) that has a shoulder portion 141 s that comes into contact with the upper end 129 e of the stem 129 and is attached to the stem 129. More specifically, the nozzle inner cylinder portion 141 has a fitting cylinder portion 141a that fits the outer surface of the stem 129 integrally hanging on the outer edge of the shoulder portion 141s, while the upper cylinder portion from the inner edge of the shoulder portion 141s. 141b stands up together.

  Reference numeral 142 denotes an elastic member placed on the shoulder 141s. The elastic member 142 of the present embodiment is a return spring that surrounds the upper cylinder portion 141b of the nozzle inner cylinder portion 141, but the elastic member to be used is not limited to this.

  Reference numeral 143 denotes an outer cylinder portion (hereinafter referred to as “nozzle outer cylinder portion”) that has an abutment surface 143f that abuts against the upper end 142e of the elastic member 142 and can be moved closer to and away from the shoulder portion 141s. More specifically, the nozzle outer cylinder portion 143 forms the external shape of the nozzle 140, and a plurality of ribs 143r are formed around the axis O on the inner side. The contact surface 143f is the lower end surface of these ribs 143r, whereby the nozzle outer tube portion 143 is elastically supported so as to be able to approach and move away from the nozzle inner tube portion 141.

  The nozzle outer cylinder part 143 is also integrally formed with a flange-shaped finger-hanging part 143a on the outer side, and an overcap 150 is detachably fitted to the upper outer region from the finger-holding part 143a. Two fitting protrusions 143p are integrally formed. The finger-hanging portion 143a may be intermittently projected without being limited to the flange shape, and the fitting projections 143p are not limited to two, and a plurality of fitting projections 143p may be formed according to the shape, Or it can replace with the protrusion formed in cyclic | annular form.

  On the other hand, as shown in FIG. 2, the inner region on the upper side from the finger-hanging portion 143a is inwardly directed toward the nozzle inner cylinder portion 141 at a position recessed by a predetermined distance X from the tip 143e of the nozzle outer cylinder portion 143. A seating surface 143s that is slanted is formed. In addition to the rib 143r, a cylindrical hanging portion 143b that slidably holds the upper cylinder portion 141b of the nozzle inner cylinder portion 141 hangs down from the seating surface 143s integrally with the inner region on the upper side from the finger hanging portion 143a. ing. The outer diameter shape of the extraction path of the nozzle 140 is determined by the upper cylinder part 141b of the nozzle inner cylinder part 141 and the hanging part 143b of the nozzle outer cylinder part 143.

  Further, in the nozzle outer cylinder portion 143, a lower cylinder portion 143c that slidably surrounds the outer surface of the nozzle inner cylinder portion 141 is integrally suspended from the finger hook portion 143a. On the outer side of the lower cylinder part 143c, two protrusions 143g that protrude integrally from the lower cylinder part 143c are formed.

  Reference numeral 144 denotes a shaft portion (hereinafter referred to as “nozzle shaft”) that has a tip portion 144e extending toward the nozzle outer tube portion 143 and is fixed to the inside of the nozzle inner tube portion 141. More specifically, a plurality of protrusions 141p are intermittently formed inside the nozzle inner cylinder portion 141, and a recess 144c is formed in the base portion 144a of the nozzle shaft 144. Are arranged inside the nozzle inner cylinder portion 141 and the nozzle outer cylinder portion 143.

  The tip portion 144e of the nozzle shaft 144 is a mortar-shaped enlarged portion having a larger diameter than the base portion 144a. As shown in FIG. 2, the back surface 144f of the enlarged portion (hereinafter referred to as “nozzle shaft enlarged portion”) 144e has a nozzle inner cylinder portion that is not subjected to external force on the nozzle outer cylinder portion 143 but only by the urging force of the elastic member 142. With the shoulder 141s of 141 and the contact surface 143f of the nozzle outer cylinder part 143 spaced apart from each other, the inner surface of the nozzle outer cylinder part 143 is sealed by contacting the seating surface 143s of the nozzle outer cylinder part 143.

  As a result, when the nozzle outer cylinder part 143 and the container body 110 are moved closer to and away from each other in order to operate the foam pump 120 and dispense the contents, as shown in FIG. 4, the resilient member 142 resists the urging force. As a result, the shoulder 141s of the nozzle inner cylinder part 141 and the contact surface 143f of the nozzle outer cylinder part 143 are brought close to each other, and the nozzle shaft enlarged part 144e is separated from the seat part 143s of the nozzle outer cylinder part 143, An annular spout 140a is formed at the tip 143e of the nozzle outer cylinder 143 together with the nozzle outer cylinder 143.

  By the way, the nozzle outer cylinder part 143 is integrally provided with two protrusions 143g protruding outward from the lower cylinder part 143c on the outside of the lower cylinder part 143c. The cap 130 according to this embodiment is shown in FIG. As shown, the cylindrical portion 132 has an inner diameter D1 of the opening 131 that is equal to or larger than the outer diameter D2 of the lower cylindrical portion 143c of the nozzle outer cylinder 143, and is connected to the opening 131. With two notches 133.

  Each of the notches 133 can pass the protrusion 143g while sliding the protrusion 143g or in a state where a gap is formed between the notches 133g.

  Accordingly, the lower end surface 143d of the protrusion 143g is rotated by rotating the nozzle outer cylinder portion 143 around the axis O in the direction of the arrow d3, or by rotating the container body 110 in the direction of the arrow d3 to shift the position of the notch 133. When the container main body 110 is pushed in, it comes into contact with the upper end 132e of the cylindrical portion 132 and becomes a contact portion that regulates the relative movement of the nozzle outer cylindrical portion 143 and the container main body 110 in the axial direction.

  Next, the operation of this embodiment will be described.

  First, when the medicine is administered to the nostril, the overcap 150 is removed from the state shown in FIG. At this time, the nozzle inner cylinder portion 141 and the nozzle outer cylinder portion 143 remain in a state in which the shoulder portion 141s and the contact surface 143f are separated from each other by the urging force of the elastic member 142, as shown in FIG. The back surface 144f of the nozzle shaft enlarged portion 144e is in contact with the seating surface 143s of the nozzle outer cylinder portion 143 and seals the inside of the nozzle outer cylinder portion 143. For this reason, even if air or contents remain in the nozzle 140 in this state, it does not leak.

  Next, the container main body 110 is held and the nozzle outer cylinder portion 143 is rotated around the axis O in the direction of the arrow d3 in FIG. 5, or the nozzle outer cylinder portion 143 is held and the container main body 110 is moved around the axis O. Rotate in the direction of arrow d3 to align the ridge 143g with the position of the notch 133. Thus, when the nozzle 140 is inserted into the nostril, the finger is hooked on the finger hook portion 143a and the bottom portion 113 of the container main body 110 is pushed, the upper end 132e of the cylindrical portion 132 of the cap 130 does not hit the protrusion 143g, and the container main body 110 Can be pushed in the direction of arrow d1.

  If the nozzle outer cylinder part 143 and the container main body 110 approach each other due to this pushing, the shoulder part 141s of the nozzle inner cylinder part 141 and the contact surface 143f of the nozzle outer cylinder part 143 against the urging force of the elastic member 142 As shown in FIG. 4, the nozzle shaft enlarged portion 144 e is separated from the seating surface 143 s of the nozzle outer cylinder portion 143, and the nozzle outer cylinder portion is disposed at the tip 143 e of the nozzle outer cylinder portion 143. 143 and an annular spout 140a are formed.

  Further, as shown in FIG. 3, the poppet 122 of the foam pump 120 is pushed into the cylinder 121 together with the stem 129, the air piston 127, the piston guide 125, and the medicine piston 124 by further pushing, and the suction port 120a The medicine piston 124 is pushed into the small diameter portion 121b along the poppet 122. Accordingly, the poppet side seal end portion 124b of the medicine piston 124 and the upper end portion 122b of the poppet 122 are separated from each other, and the medicine pressurized in the filling space Rc is pumped toward the ball 126 and lifts the ball 126. The stem 129 passes through the spout 140a of the nozzle 140 to the outside.

  At the same time, the internal pressure of the filling space Ra also increases due to the pushing of the air piston 127, so that the lower end of the air piston 127 releases the seal with the piston guide 125 and leads the filling space Ra to the gap between the air piston 127 and the piston guide 125. Therefore, the air pressurized in the filling space Ra also passes through the upper part of the ball 126 to the outside through the stem 129 and the spout 140a of the nozzle 140.

  At this time, in the foam pump 120, the drug piston 124 moves to return to the original position by the elastic force of the return spring 123, the poppet side seal end part 124b of the drug piston 124, and the upper end part of the poppet 122 When re-engaging with 122b, the poppet 122 is pulled up to return to the original position together with the medicine piston 124 and the like. Thereby, the medicine filled in the container main body 110 is introduced into the filling space Rc from the suction port 120a with the negative pressure generated in the filling space Rc.

  At the same time, the air piston 127 moves to return to the original position together with the piston guide 125, and the air piston valve 128 opens the through hole 127c and introduces air into the filling space Ra due to the negative pressure generated by the expansion of the filling space Ra. At the same time, the air piston 127 and the piston guide 125 come into contact again to close the gap.

  Next, when the finger is released from the finger-hanging portion 143a, the nozzle inner cylinder portion 141 and the nozzle outer cylinder portion 143 are again brought into contact with the shoulder portion of the nozzle inner cylinder portion 141 by the urging force of the elastic member 142 as shown in FIG. 141s and the contact surface 143f of the nozzle outer cylinder part 143 are returned to a separated state, and the back surface 144f of the nozzle shaft enlarged part 144e comes into contact with the seating surface 143s of the nozzle outer cylinder part 143, and the nozzle outer cylinder part The inside of 143 is sealed.

  Thereafter, when the container body 110 is pushed into the nozzle outer cylinder 143 by further hooking the finger on the finger hook 143a to pour out the contents, the nozzle inner cylinder 141 in the nozzle 140 resists the urging force of the elastic member 142. The shoulder portion 141s of the nozzle and the contact surface 143f of the nozzle outer cylinder portion 143 are brought close to each other, and the nozzle shaft enlarged portion 144e is separated from the seat surface 143s of the nozzle outer cylinder portion 143, and again this nozzle outer cylinder portion An annular spout 140a is formed at the tip 143e of 143 together with the nozzle outer cylinder 143.

  When the container body 110 is further pushed into the nozzle outer cylinder 143, the poppet 122 is seated on the back surface of the suction port 120a, and then the drug piston 124 is pushed along the poppet 122, and the drug piston 124 and the poppet 122 The drug which is separated and pressurized in the filling space Rc lifts the ball 126 and is pumped toward the stem 129. At the same time, as the air piston 127 is pushed in, the internal pressure of the filling space Ra also rises again, the air piston 127 is displaced from the piston guide 125, and air is pumped to the stem 129 through the upper part of the ball 126.

  Thereby, after the medicine and air are mixed at the upper part of the ball 126, a foamy medicine is formed through each of the two mesh rings Rm in the stem 129, and the gap between the nozzle outer cylinder 143 and the nozzle shaft 144 is formed. From the annular spout 140a formed in the above, it is poured out as a foamy medicine.

  When the finger is removed from the finger-hanging portion 143a after the medicine has been dispensed, the nozzle inner cylinder portion 141 and the nozzle outer cylinder portion 143 are moved into the nozzle again by the biasing force of the elastic member 142 as shown in FIG. The shoulder portion 141s of the tube portion 141 and the contact surface 143f of the nozzle outer tube portion 143 are returned to a separated state, and the back surface 144f of the nozzle shaft enlarged portion 144e is in contact with the seat surface 143s of the nozzle outer tube portion 143. Then, the inside of the nozzle outer cylinder portion 143 is sealed. For this reason, even if the contents remain in the nozzle 140, the contents do not leak.

  That is, according to the present embodiment, the relationship between the nozzle inner cylinder portion 141 and the nozzle outer cylinder portion 143 is determined by the biasing force of the elastic member 142 unless the nozzle 140 and the container main body 110 are moved closer to or away from each other. Since the nozzle shaft enlarged portion 144e is in contact with the seating surface 143s of the nozzle outer cylinder portion 143 to seal the inside of the nozzle outer cylinder portion 143, the Even when the cap 150 is removed, the residue in the nozzle 140 does not leak.

  On the other hand, in this embodiment, if the nozzle 140 and the container body 110 are moved closer to and away from each other in order to operate the foam pump 120 to discharge the contents, the nozzle inner cylinder is resisted against the urging force of the elastic member 142. The shoulder portion 141s of the portion 141 and the contact surface 143f of the nozzle outer cylinder portion 143 are brought close to each other, and the back surface 144f of the nozzle shaft enlarged portion 144e is separated from the seating surface 143s of the nozzle outer cylinder portion 143. Since the annular spout 140a is formed at the tip 143e of the outer cylinder part 143 together with the nozzle outer cylinder part 143, the operation of approaching and separating the nozzle outer cylinder part 143 and the container body 110 can be performed without stopping. The dispensing operation can be performed.

  In addition, according to the present embodiment, since the mechanism for pumping the liquid content to the nozzle 140 is the foam pump 120, the liquid content poured out by inserting the nozzle 140 into a cavity such as a nostril contains air. Since it becomes foamy, the burden placed on the inner wall of the hollow portion when the nozzle 140 is inserted into the hollow portion and the contents are poured out can be reduced.

  In addition, according to the present embodiment, if the nozzle outer cylinder part 143 and the container body 110 are moved closer to and away from each other in order to operate the foam pump 120 and dispense the contents, the nozzle shaft enlarged part 144e In order to form the annular spout 140a with the nozzle outer cylinder 143 away from the seating surface 143s of the cylinder 143, the cavity when the nozzle 140 is inserted into the cavity such as a nostril and the contents are poured out. The content can be poured out uniformly over the entire inner wall of the hollow portion while reducing the burden on the portion.

  Furthermore, when the back surface 144f of the nozzle shaft enlarged portion 144 is an inclined surface that guides the content poured out from the annular spout 140a obliquely forward as in this embodiment, the nozzle 140 is inserted into a cavity such as a nostril. In order to dispense the contents evenly over the entire inner wall of the cavity part while reducing the burden on the cavity part when the contents are poured out in the above, the inner wall near the tip (143e) of the nozzle 140 The contents can be poured out in a focused manner.

  In the present invention, the shoulder part 141s of the nozzle inner cylinder part 141 and the contact surface 143f of the nozzle outer cylinder part 143 are resisted against the urging force of the elastic member 142 to operate the foam pump 120 to dispense the contents. When approaching, the distance between these can be regulated by contacting the shoulder 141s and the contact surface 143f, but as in this embodiment, the stem 129 is on the outside, If the stopper 129s that integrally restricts the movement of the nozzle outer cylinder portion 143 due to the approach between the shoulder 141s and the contact surface 143f is integrally provided, the stopper 129s is provided outside the stem 129 in a relatively simple method. The interval (play) between the nozzle inner cylinder portion 141 and the nozzle outer cylinder portion 143 can be easily changed according to the user and application.

  Furthermore, in this embodiment, the opening 131 of the cap 130 has a shape that allows the nozzle 140 and the container main body 110 to approach and separate from each other, and has a notch 133 connected to the opening 131, and the nozzle outer cylinder portion. 143 has two protrusions 143g on the outer side thereof, which are combined with the notch 133 to allow approach and separation from the container main body 110, and the protrusion 143g is an axis of the container main body 110 or the nozzle outer cylinder 143. When the nozzle 140 and the container main body 110 are brought close to each other by rotating around the O and shifting the position of the notch 133, the nozzle outer cylinder portion 143 comes into contact with the upper edge 132e of the cylindrical portion 132 of the cap 130. If the contact portion 143d for restricting the approach of the container main body 110 is provided, the movement of the nozzle 140 and the container main body 110 that cause the operation of the foam pump 120 is changed, and the outer cylinder portion 143 of the nozzle 140 and the opening 131 of the cap 130 are changed. In other words, the container body 110 or the nozzle 140 is simply rotated around the axis O. Since it can be controlled by a simple operation, it is possible to prevent erroneous injection without enlarging the size of the overcap 150 so that the entire nozzle 140 is covered with the overcap.

  Note that the opening 131 of the cap 130 may directly open the top wall without forming the cylindrical portion 132. In this case, the protrusion 143g comes into contact with the top wall 130a of the cap 130 and regulates the approach between the nozzle outer cylinder 143 and the container body 110.

  The dispenser 100 of the present invention can exert its effects remarkably by using it as a nasal drop dispenser used to administer nasal drops to the nostrils.

  FIG. 6 is a partial cross-sectional view showing an enlarged nasal dispenser 200 of the second embodiment of the present invention.

In addition, the diameter of the nozzle outer cylinder portion 143 can be reduced.

  By the way, FIG. 7 is a partial cross-sectional view showing an enlarged nasal administration device 300 of the third embodiment of the present invention. The container 300 shown in FIG. 7 also has a symmetrical shape with respect to the axis O as the starting point, and the same parts as those in other drawings are denoted by the same reference numerals and description thereof is omitted.

  According to the present invention, as shown in FIG. 7, in the state where the shoulder 141s of the nozzle inner cylinder part 141 and the contact surface 143f of the nozzle outer cylinder part 143 are separated by only the urging force of the elastic member 142, The nozzle shaft expanding portion 144e may be configured to protrude from the tip 143e of the nozzle outer cylinder portion 143, and the back surface 144f may be detachably contacted with the tip 143e of the nozzle outer cylinder portion 143. Also in this embodiment, since the back surface 144f of the nozzle shaft enlarged portion 144e is an inclined surface that guides the contents to be poured out from the spout 140a obliquely forward, the tip 143e of the nozzle outer cylinder portion 143 has a nozzle inner cylinder. It becomes an inclined surface that approaches the axis O as it goes to the portion 141.

  According to such a configuration, the tip 143e of the nozzle outer cylinder portion 143 serves as a seating surface 143s, and the nozzle spout 140a can be completely sealed, preventing entry of dust and the like from the nozzle tip 143e to the inside even without an overcap. The nozzle 140 can always be kept clean. This configuration is a modification based on the second embodiment, but can be appropriately changed based on the first embodiment.

  Further, as in each of the above embodiments, if the container body 110 includes the bottom 113 having a minimum diameter near the cylinder tip portion 120s of the foam pump 120, the residual content can be reduced, and further The container body 110 can be reduced in weight.

  Furthermore, as in the above embodiments, the cylinder 121 has a tapered tip portion 120p, and if the edge of the tip portion 120p is provided with a notch S leading into the cylinder 121, the bottom of the container body 110 Even if the dimension of the container body 110 in the direction of the axis O (height dimension) is shortened while minimizing the diameter 113, it is possible to prevent the spout 120a at the tip of the cylinder from being closed on the inner surface of the bottom 113 of the container body 110, It is possible to reliably inject the contents, and to minimize the residual of the medicine after use.

  Further, the nozzle 140 according to each of the above-described forms is used to uniformly dispose of the drug on the entire inner wall of the nostril while suppressing the discomfort given to the user when administering the drug to the nostril. By changing the area of the opening of the tip 143e of the portion 143, the shape of the enlarged portion 144e of the shaft 144, the shape of the base 144a, etc., the inner wall of the nostril near the tip 143e of the nozzle outer cylinder 143 is emphasized. A drug can be administered.

  The nozzle shaft enlarged portion 144e can be separated from the base portion 144a. In this case, even when the nozzle shaft enlarged portion 144e protrudes from the tip 143e of the nozzle outer cylinder portion 143, it is not necessary to forcibly push it from the portion opened at the tip 143e of the nozzle outer cylinder portion 143.

  Further, FIG. 8 is an enlarged perspective view illustrating another shape of the notch 133 leading to the opening 131 of the cap 130 according to the present invention.
