Description

  The present invention relates to a feeding container that feeds and uses contents from the container, such as lipstick and lip balm. The contents stored in such a feeding container, that is, the materials to be fed, are typically formed in a relatively soft stick shape such as lipstick or lip balm. Finishing of shadows, blushers, creams (base, whitening, facial cleansing, cleansing, etc.) or cosmetics for skin, hair cosmetics such as hairdressing, hair dye, hair treatment, special use such as sunscreen or sunscreen Cosmetics, fragrances, haptics, skin protectants, disinfectants, medical coating agents such as anti-smudge agents, office supplies such as stick glue, socks, anti-fogging and scratch repair materials for car accessories, stains There are various uses such as taking goods and miscellaneous goods such as shoe ink.

  As shown in FIGS. 8 and 9, this type of feeding container relatively rotates a guide cylinder 2 having a guide hole 2a in the vertical direction in a cylindrical container body 1 having a spiral groove 1a on the inner peripheral surface. The cup 3 that accommodates and holds the material to be fed is accommodated in the guide cylinder 2, and the spiral of the inner peripheral surface of the container body 1 is provided on the outer surface of the cup 3 through the guide hole 2 a of the guide cylinder 2. An engagement protrusion 4 that engages with the groove 1a is provided, and the cup 3 can be moved up and down with respect to the container body 1 by the relative rotation of the container body 1 and the guide tube 2, and the material to be fed is fed out.

  By the way, conventionally, in order to use the material left in the cup 3 without waste, the cup 3 is made into a double structure of a cup body 3a and a bottom member 3b that can be moved up and down in the cup body 3a. After the cup 3 is drawn out above the container body, the bottom member 3b can be further moved with respect to the cup body 3a in a state where the movement of the cup body 3a is restricted. The inventors of the present application have already disclosed what is pushed up above the cup body 3a (Patent Document 1, Patent Document 2).

JP-A-9-169374 JP 2000-342329 A

  As described above, the cup 3 that holds the object to be fed is made into a double structure of the cup body 3a and the bottom member 3b, and after the normal feeding of the cup 3, the bottom member 3b of the cup 3 is further raised. The feeding container that can be used has the advantage that the material to be fed in the cup 3 can be used without waste.

In this type of feeding container, a plurality of steps of engaging grooves 6 are formed in a step shape on the outer peripheral surface of the bottom member 3b, and a protrusion 7 that engages with the engaging grooves 6 on the outer surface of the bottom member 3b is formed in the cup body 3a. In a state where the formed material is sufficiently left in the container without being reduced, the bottom member 3b accommodated in the cup body 3a is pushed into the lower end of the cup body 3a as shown in FIG. 9B. The protrusion 7 is engaged with the uppermost engaging groove 6 on the outer surface of the bottom member 3b. And when the amount of the to-be-delivered thing decreases and it is going to use the to-be-delivered object which remains in the cup main body 3a, in the state which restricted the movement of the cup main body 3a, it is stronger than the force required for normal pay-out The container body 1 and the guide cylinder 2 are rotated relative to each other by force, and the bottom member 3b is strongly pushed up with respect to the cup body 3a, whereby the tick and the projection 7 of the cup body 3a are moved downward from the uppermost engaging groove 6 in order. 9, over the weir-shaped protrusions between the engagement grooves 6, and sequentially move to the lower engagement grooves 6. As shown in FIG. 9C, the cup body 3 a On the other hand, the bottom member 3b is pushed up sequentially, and the material to be fed remaining in the cup body 3a can be used up to the end.
On the other hand, in a state where movement of the cup body 3a is restricted from the position shown in FIG. 9C, the tick and the protrusion 7 of the cup body 3a are moved from the lowermost engagement groove 6 to the upper engagement groove 6 in order. When moving over the weir-like protrusions between the engaging grooves 6 toward the bottom, the bottom member 3b can be returned to the position shown in FIG. 9B with respect to the cup body 3a.

By the way, if the resistance when moving the tick and the protrusion 7 of the cup body 3a over the weir-shaped protrusion between the engaging grooves 6 is large, the impact when the protrusion 7 fits into the engaging groove 6 is large. Therefore, due to the impact, the material to be fed may come off the support surface on the upper surface of the bottom member 3b, and the material to be fed may fall off.
On the other hand, if the resistance when moving the tick and the protrusion 7 of the cup body 3a over the weir-like protrusions between the engaging grooves 6 is too small, there is enough to-be-delivered and the cup Even when it is not necessary to feed out the delivery object in the main body 3a, the delivery object protrudes more than usual, and the delivery object is easily broken or dropped off.
Thus, the resistance required for the movement of the bottom member 3b in the cup body 3a should not be too strong or too weak.

  Therefore, according to the present invention, the resistance when the tick and the protrusion 7 of the cup body 3a move over the weir-like protrusions between the engaging grooves 6 is not too strong and not too weak. It is intended to obtain a feeding container having a structure that can be maintained.

  In order to solve the above-described problems, the present invention accommodates a guide cylinder 2 having a guide hole 2a in the vertical direction in a cylindrical container body 1 having a spiral groove 1a on the inner peripheral surface so as to be relatively rotatable. The guide tube 2 accommodates a double-structured cup 3 that holds a material to be fed, which includes a cylindrical cup body 3a and a bottom member 3b that is movably accommodated in the cup body 3a. An engaging projection 4 is provided on the side of the bottom member 3b so as to penetrate the cup body 3a and the guide cylinder 2 and engage with the spiral groove 1a of the container body 1, and the guide cylinder 2 is rotated relative to the container body 1. Thus, the double-structured cup 3 can be moved in the vertical direction along the spiral groove 1a, and the bottom member 3b can be further moved relative to the cup body 3a in a state where the movement of the cup body 3a is restricted. The bottom of the cup 3 A plurality of engaging grooves 6 are formed on the outer surface of the material 3b, and protrusions 7 that can be sequentially engaged with and disengaged from the plurality of engaging grooves 6 in the vertical direction are formed on the inner surface of the cup body 3a. The engagement groove 6 and the protrusion 7 can be engaged and disengaged by the relative elastic deformation of each other.

  In this way, by allowing the engagement grooves 6 and the projections 7 to be engaged and disengaged by a plurality of relative elastic deformations, the tick and the projections 7 of the cup body 3 a can be connected between the engagement grooves 6. The resistance at the time of moving over the weir-like protrusions can be maintained at an appropriate strength that is not too strong and not too weak.

  Relative elastic deformation of the protrusion 7 on the inner surface of the cup body 3 a with respect to the plurality of stages of the engagement grooves 6 can be achieved by providing a bending space on the back side of the engagement grooves 6 or the protrusions 7.

  Further, the upper and lower inner wall surfaces of the plurality of engaging grooves 6 facing each other are inclined surfaces that open outward, so that the protrusion 7 of the cup body 3 a has a dam-like protrusion between the engaging grooves 6. It is possible to weaken the resistance when moving over the vehicle.

  The inclination angle of the inclined surface is below the engaging groove 6 with which the protrusion 7 of the cup body 3a comes into contact when the bottom member 3b is drawn out of the upper and lower inner wall surfaces of the engaging groove 6 with respect to the cup body 3a. By forming the inclination of the inner wall surface to be steeper than the inclination of the upper wall surface, the protrusion 7 of the cup body 3a has each engaging groove in the direction in which the bottom member 3b is fed to the cup body 3a. The resistance at the time of moving over the weir-like protrusions between the six members can be increased, and the resistance in the opposite direction, that is, the direction in which the bottom member 3b is pulled back with respect to the cup body 3a can be decreased.

  Also, the protrusions 7 of the cup body 3a can be connected to each other by making the upper and lower wall surfaces of the protrusions 7 formed on the inner surface of the cup body 3a tapered toward the engagement groove 6 of the bottom member 3b. The resistance at the time of moving over the weir-like protrusions between the joint grooves 6 can be weakened.

  Among the upper and lower inclined surfaces of the protrusion 7, when the bottom member 3 b is extended with respect to the cup body 3 a, the inclination angle of the lower inclined surface of the protrusion 7 contacting the inner wall surface of the engagement groove 6 is By forming the base member 3b with respect to the cup body 3a by forming it more steeply than the inclined surface, the protrusion 7 of the cup body 3a gets over the weir-like protrusions between the engaging grooves 6. The resistance at the time of moving can be strengthened, and the resistance in the opposite direction, that is, the direction of pulling back the bottom member 3b with respect to the cup body 3a can be weakened.

  Next, the anchor protrusion 12 embedded in the lower surface of the delivery object is provided on the upper surface of the bottom member 3b, so that the removal of the delivery object can be more effectively prevented.

On the inner surface of the cup body 3a, protrusions 13 embedded in the outer surface of the object to be fed may be provided in the vertical direction.
In the lower part of the guide tube 2, a flange portion 10 that projects downward from the container body 1 may be provided.

  As described above, according to the present invention, the resistance when the tick and the protrusion 7 of the cup body 3a move over the weir-like protrusions between the engagement grooves 6 is neither too strong nor too weak. Since it can be kept at an appropriate strength, it is possible to more effectively prevent the material to be fed from falling off.

  1 to 4 show an embodiment of a feeding container according to the present invention. In addition, the code | symbol has attached | subjected the code | symbol common to the member which is common in the prior art example shown in FIG.8 and FIG.9.

  As shown in FIG. 1 (c), the feeding container according to the present invention is accommodated in a cylindrical container body 1 having a spiral groove 1a formed on the inner peripheral surface thereof, and relatively rotatable in the cylindrical container body 1. The guide cylinder 2 has a guide hole 2a in the vertical direction, and the cup 3 holds a material to be fed housed in the guide cylinder 2.

  At the lower part of the guide tube 2, a flange portion 10 that projects downward from the container body 1 is formed so that the guide tube 2 can be rotated while holding the container body 1. Further, the upper end of the guide hole 2a of the guide cylinder 2 is cut by a slit 9 so that the upper end of the guide cylinder 2 can be widened when the cup 3 is assembled into the guide cylinder 2. Yes.

  Two spiral grooves 1a are formed on the inner peripheral surface of the container body 1 so as to face each other with an interval of 180 degrees in the circumferential direction.

  As shown in FIG. 1A, the cup 3 has a double structure of a cup body 3a and a bottom member 3b accommodated in the cup body 3a so as to be movable up and down.

  The bottom member 3b is formed of a cylindrical member having a thickness that can be inserted into the inside of the cup body 3a, and has a support surface that supports an end portion of an object to be fed such as a lipstick at one end portion thereof. In the center of the support surface, a filling hole 11 is provided for use in molding and filling a delivery object such as lipstick. At the lower end of the outer surface of the cylindrical bottom member 3b, an engagement protrusion 4 that engages with the spiral groove 1a on the inner peripheral surface of the container body 1 through the guide hole 2a of the guide cylinder 2 is separated by 180 degrees in the circumferential direction. One is formed at each position. Since the engagement protrusion 4 is engaged with the spiral groove 1a on the inner peripheral surface of the container body 1, when the container body 1 and the guide tube 2 are rotated relative to each other, the engagement protrusion 4 is moved along the spiral groove 1a. The bottom member 3b moves up and down along the guide hole 2a of the guide tube 2.

  The cup body 3a is provided about twice as long as the bottom member 3b, and has a notch 8 that guides the engaging protrusions 4 of the bottom member 3b in the vertical direction from the middle to the opposite position of the lower part.

  On the outer peripheral surface of the bottom member 3b, a plurality of steps of engaging grooves 6 are formed along the peripheral surface in a stepped manner, and in the cup body 3a, protrusions that engage with the engaging grooves 6 on the outer surface of the bottom member 3b. 7 is formed, and in the state where the material to be fed is sufficiently in the container, as shown in FIG. 2A, the position where the bottom member 3b accommodated in the cup body 3a is pushed into the lower end of the cup body 3a. The protrusion 7 is engaged with the uppermost engaging groove 6 on the outer surface of the bottom member 3b. Then, when the remaining material to be fed is reduced and the material to be left in the cup body 3a is further lifted by the bottom member 3b of the cup 3, and the material to be left in the cup body 3a is to be used. When the container body 1 and the guide cylinder 2 are relatively rotated with a force stronger than that required for normal feeding and the bottom member 3b is pushed up with respect to the cup body 3a, the tick and the protrusion 7 of the cup body 3a are moved to the uppermost stage. 2c in order from the engagement groove 6 toward the lower engagement groove 6 over the weir-like protrusions between the engagement grooves 6, and sequentially moves to the lower engagement groove 6. FIG. As shown in FIG. 3, the bottom member 3b is sequentially pushed up with respect to the cup body 3a, and the material to be fed remaining in the cup body 3a can be used up to the end.

  On the contrary, from the position shown in FIG. 2C, the tick and the protrusion 7 of the cup body 3a are moved from the lowermost engaging groove 6 to the upper engaging groove 6 in order, between the engaging grooves 6. By moving over the weir-shaped protrusion, the bottom member 3b can be returned to the position shown in FIG. 2A with respect to the cup body 3a.

  A plurality of anchor projections 12 are formed on the support surface on the upper surface of the bottom member 3b to pierce the lower surface of an object to be fed such as lipstick. Also, a plurality of vertical ridges 13 are formed in the upper half of the inner surface of the cup body 3a so as to be buried in the outer periphery of the object to be fed after molding. The material to be fed such as lipstick can be formed by pouring the material of the material to be fed such as lipstick from below the filling hole 11 in a state where a molding die is put on the upper part of the cup body 3a.

  By causing the anchor protrusion 12 on the upper surface of the bottom member 3b to pierce the lower surface of the object to be fed such as lipstick, and further so that the protrusion 13 on the inner surface of the cup body 3a is embedded in the outer surface of the object to be fed. Even when the bottom member 3b is ticked up with respect to the cup body 3a when using the unrolled object remaining in the cup body 3a, the to-be-drawn object is firmly held by the cup body 3a. In addition, since the protrusion 13 on the inner surface of the cup body 3a serves as a guide for the material to be fed, the material to be fed in the cup body 3a can be smoothly moved up and down.

  A stopper hole 2b is formed in the guide tube 2 in parallel with the guide hole 2a, and a stopper projection 5 that fits into the stopper hole 2b is formed on the outer surface of the cup body 3a.

  At the upper end of the stopper hole 2b, a bent portion on which the stopper projection 5 of the cup body 3a is caught in a state in which the container body 1 and the guide tube 2 are relatively rotated so that the upper end of the cup body 3a is extended to the vicinity of the upper end of the container body 1. When 2c is formed and the stopper protrusion 5 is hooked on the bent portion 2c of the stopper hole 2b, the cup body 3a is not further drawn upward. Therefore, when the container body 1 and the guide tube 2 are further rotated in the direction in which the cup body 3a is pushed up while the cup body 3a is not drawn upward, the protrusion 7 of the cup body 3a is disengaged from the uppermost engaging groove 6. The bottom member 3b is engaged with the lower engaging groove 6 in order, and the bottom member 3b moves upward with respect to the cup body 3a in the cup body 3a. Sequentially extruded upward.

Further, at the lower end of the stopper hole 2b, when the cup body 3a is lowered to the lowermost position of the container body 1, the stopper projection 5 is formed when the container body 1 and the guide tube 2 are relatively rotated in the lowering direction. A bent portion 2d to be fitted is formed, and the cup body 3a is not further lowered at a position where the stopper projection 5 is engaged with the bent portion 2d.
Then, the cup body 3a is released at the position where the cup body 3a is lowered to the lowest position of the container body 1 so that the engagement between the stopper protrusion 5 and the bent portion 2d at the lower end of the stopper hole 2b can be released. A wide portion 2e is provided in the lower portion of the guide hole 2a of the guide tube 2 so as to be rotated in the direction.

  In the above embodiment, when the tick and the protrusion 7 of the cup body 3a move over the weir-like protrusions between the engaging grooves 6, as shown in FIG. The cylindrical space on the back side functions as a bending space B for elastically bending, and can provide an appropriate resistance when the protrusion 7 moves over the weir-like protrusions between the engaging grooves 6. .

  In addition, a bending space A is also formed on the back side of the protrusion 7 of the cup body 3a, and the protrusion 7 of the cup body 3a also moves over the weir-shaped protrusions between the engaging grooves 6 by this bending space A. The resistance at the time is adjusted moderately.

  When the protrusion 7 of the cup body 3a has a strong resistance when moving over the weir-like protrusions between the engaging grooves 6, as shown in FIG. By making the upper and lower inner wall surfaces 6a and 6b opposite to each other into inclined surfaces that open outward, the tick and the protrusion 7 of the cup body 3a move over the weir-like protrusions between the engaging grooves 6 The resistance at the time of making it can be weakened.

  However, if the resistance becomes too weak, the bottom member 3b moves in the cup body 3a in a normal use, that is, in a state where a lot of the to-be-drawn object still remains, and the to-be-delivered object protrudes more than usual. As a result, the material to be fed becomes easy to drop off. As a result, the angle (α) is desirably steep, that is, about 91 to 45 degrees. This angle (α) varies greatly depending on various conditions such as the material of the bottom member 3b and the cup body 3a, the height, width and shape of the protrusion 7, the depth and width of the engagement groove 6, and the like. The above values are for reference only because they may fall outside this range.

  When the material to be fed is reduced and the bottom member 3b is moved in the feeding direction in the cup body 3a, the container body 1 and the flange portion 10 of the guide tube 2 are rotated with the intention to further feed, and a certain amount of resistance is felt. If it is not in a state where it is extended, there is no meaning in the engagement structure of the protrusion 7 and the engagement groove 6, so that the size of the bending space (A) (B), the thickness setting of the bottom member 3b and the cup body 3a, or the angle (Α) is preferably set while confirming the expression of a certain resistance.

  Next, as shown in FIG. 5 (b), when the inclination angle of the inclined surface is extended from the upper and lower inner wall surfaces of the engagement groove 6 to the cup body 3a, the bottom member 3b is extended. By forming the inclination (angle α) of the lower inner wall surface 6a of the engaging groove 6 with which the protrusion 7 of 3a abuts to be steeper than the inclination (angle β) of the upper inner wall surface 6b, the bottom member 3b is formed. In the feeding direction with respect to the cup body 3a, the tick and the protrusion 7 of the cup body 3a increase the resistance when moving over the weir-like protrusions between the engaging grooves 6, and the opposite direction, that is, the cup The resistance in the direction of pulling back the bottom member 3b with respect to the main body 3a can be weakened. By adopting such an inclined structure, when the object to be fed is further fed, as described above, a resistance to the extent that it is necessary to forcibly rotate with a certain degree of will be given, and the unrolled object that has been forcibly fed out. When storing the feeding material, the resistance is as small as possible and it can be stored smoothly. Normally, the angle α is about 91 ° to 45 ° as described above, but the angle β may exceed 45 and be about 10 °. However, as described above, these angles vary greatly depending on various conditions such as the material of the bottom member 3b and the cup body 3a, the height, width and shape of the protrusion 7, the depth and width of the engaging groove 6. There are cases where it is out of this range depending on the design, so the above values are reference values. The steep and gentle slopes mean the relative difference between the angle α and the angle β, and if the angle difference is 2 degrees or more, preferably 5 degrees or more, it is possible to realize resistance feeding and storage with less resistance. it can.

  Next, FIG.5 (c) is an example which made the upper and lower wall surfaces 7a and 7b of the processus | protrusion 7 formed in the inner surface of the cup main body 3a taper toward the engagement groove 6 of the bottom member 3b. Even in this example, the resistance when the tick and the protrusion 7 of the cup body 3 a move over the weir-like protrusions between the engaging grooves 6 can be weakened. In the example of FIG. 5C, of the upper and lower inclined surfaces of the protrusion 7, when the bottom member 3b is extended to the cup body 3a, the protrusion 7 is in contact with the inner wall surface of the engagement groove 6. By forming the inclined angle of the inclined surface 7a so as to be steeper than that of the upper inclined surface 7b, the protrusion 7 of the cup body 3a has each engagement in the direction of feeding the bottom member 3b to the cup body 3a. It is possible to increase the resistance when moving over the weir-like protrusions between the joint grooves 6, and to weaken the resistance in the opposite direction, that is, the direction in which the bottom member 3b is pulled back with respect to the cup body 3a. It gives the resistance necessary to force it to rotate with the will of the will, and when storing the object that has been forcibly extended, there is as little resistance as possible and it can be stored smoothly, usually with a steep slope The angle is 91 degrees to 45 as described above. Is a degree, the angle of the gentle slope is considered about 10 degrees beyond 45.

Next, the assembly procedure of the feeding container will be described.
First, as shown in FIG. 1A, a double-structured cup 3 is assembled.
The cup 3 is assembled by fitting the bottom member 3b from the lower end of the cup body 3a into the notch 8 of the cup body 3a so that the engaging protrusion 4 of the bottom member 3b is fitted, and the uppermost part of the bottom member 3b. When the protrusion 7 on the inner surface of the cup body 3a is engaged with the engaging groove 6, the cup body 3a and the bottom member 3b are coupled as shown in FIG.

  Next, the assembled cup 3 is accommodated in the guide tube 2 from above the guide tube 2 as shown in FIG. When the cup 3 is pushed in from above the guide tube 2, the slit 9 at the upper end of the guide hole 2b of the guide tube 2 is opened, and the engagement protrusion 4 of the bottom member 3b is inserted into the guide hole 2a and the cup body 3a. The stopper protrusion 5 is fitted into the stopper hole 2b.

  Then, the assembly of the feeding container is completed by covering the guide body 2 with the container body 1 so that the engagement protrusion 4 of the cup 3 fits into the spiral groove 1a of the container body 1.

Next, FIG. 6 shows another embodiment of the feeding container according to the present invention.
In this feeding container, a sheath tube 14 to be fed is integrally formed on the upper portion of the guide cylinder 2, and a stopper projection 5 is formed in an annular shape around the cup body 3a, as shown in FIG. 6 (b). In the state where the cup 3 is raised to the position, the stopper projection 5 is made to contact the lower end surface of the sheath tube 14 so that the cup body 3a is not further drawn upward. It differs from the embodiment shown. Since other basic configurations are the same as those of the embodiment shown in FIGS. 1 to 5, the same reference numerals are given and description thereof is omitted.

  Also in the embodiment of FIG. 6, the cup 3 is raised so that the stopper projection 5 contacts the lower end surface of the sheath tube 14, and the container body 1 and the guide cylinder 2 When the cup body 3a is rotated in the direction of pushing up the cup body 3a, the projection 7 of the cup body 3a is engaged from the uppermost engaging groove 6 to the lower engaging groove 6 in order, and the bottom member 3b in the cup body 3a. Moves upward with respect to the cup body 3a, and the material to be fed in the cup body 3a is sequentially pushed out above the cup body 3a, so that the material to be fed can be used up to the end.

  As shown in FIG. 7 (d), in this example, in order to make the protrusion 7 more easily bent, openings 20 are provided on both sides of the protrusion 7 substantially in parallel along the moving direction of the bottom member 3b. Is. This increases the smoothness of the protrusion 7 when it moves between the engaging grooves 6 of the bottom member 3b, and the feel when moving becomes soft, and the feeling of luxury increases depending on the material to be constructed.

  Further, in this example, as shown in FIG. 7E, an annular skirt-like portion 21 slightly extended outward is formed on the outer edge of the end of the bottom member 3b on the side that holds the object to be fed. Is forming. The outer diameter of the annular skirt-shaped portion 21 is substantially equal to the inner diameter of the cup body 3a to be inserted, that is, is in contact with the inner surface of the cup body 3a. In this way, it is possible to support the margin of the outer edge of the delivery object when pushing up the delivery object, and even if the delivery object is in a fixed state on the inner surface of the cup body 3a, good movement can be achieved. Is possible.
