Description

  The present invention relates to a discharge container in which contents stored in a storage container by a pressing operation of a pressing head are discharged from a nozzle.

  Conventionally, this type of discharge container is often used as a container for storing contents such as milky lotion and hairdressing material.

  Such a discharge container with a pressing head is configured such that the contents are discharged when the pressing head is pressed down.For example, when the container is carried in a bag or the like, the pressing head is unexpectedly pressed down to cause the contents to be discharged. There is a risk of being discharged. Therefore, a discharge container has been developed in which a cover is attached to the outer peripheral side of the container and the outer periphery of the pressing head is covered with the cover when not in use so as to prevent the pressing head from being pushed down unexpectedly. Yes.

  For example, Patent Document 1 has a configuration in which a cover is attached to the outer peripheral side of a cylindrical body attached to a storage container, and a protrusion provided on an inner peripheral surface of the cover is engaged with a spiral groove provided in the cylindrical body. Occasionally, the cover covers the outer periphery of the push-down head to prevent erroneous operation, and when in use, the cover can be rotated to lower the cover with respect to the container and the push-down head can be pushed down. A discharge container that can be exposed up to is described.

JP2011-136722A

  However, the conventional discharge container has a structure in which the pressing head gradually protrudes from the cover as the cover is rotated. For example, when the cover is rotated while holding the top surface by hand. If the hand touches the pressing head during the rotation operation, the pressing head may be accidentally pressed down and the contents may be discharged unexpectedly.

  An object of the present invention is to solve such a conventional problem, and an object of the present invention is to inadvertently discharge the contents by accidentally pressing down the pressing head during the rotation of the cover. It is in providing the discharge container which can prevent this.

  The discharge container of the present invention is a discharge container comprising a storage container for storing contents and a pressing head for discharging the contents in the storage container by being pushed down.

A movable cylindrical cover, a spiral groove provided in one of the cylindrical body or the cover, and a protrusion provided in the other of the cylindrical body or the cover and disposed in the spiral groove. A conversion mechanism that converts a displacement of the cover in the rotational direction about the axis of the cylinder relative to the cylindrical body into an axial displacement of the cover relative to the cylinder, and an axial direction provided in the cylinder. On the facing support surface And is connected to the cover so as to be capable of relative movement and integral rotation in the axial direction, and when the cover is in the closed position or between the closed position and the open position, an engagement provided in the push-down head. A stopper that abuts the joint portion from the axial direction to restrict the push-down head from being pushed down, and that allows the push-down head to be pushed down by shifting in the circumferential direction with respect to the engagement portion when the cover is in the open position. And a member.

  In the above configuration, the stopper member is provided with an arc-shaped stopper wall extending in a predetermined angular range along the circumferential direction, the pressing head is provided with a cylindrical portion having a smaller diameter than the stopper wall, and the engaging portion is It is preferable to use a vertical rib that protrudes from the outer peripheral surface of the cylindrical portion and can abut against the axial end surface of the stopper wall from the axial direction.

  In the above configuration, the support surface is provided with a non-rotating cylindrical wall, and the pressing head is attached to the cylindrical body by engaging a non-rotating projection provided on the cylindrical portion with a groove provided on the non-rotating cylindrical wall. It is preferable to prevent rotation.

  According to the present invention, when the cover is in the open position, the stopper member is displaced in the circumferential direction with respect to the engaging portion provided in the pressing head, so that the pressing head can be pressed down, while the cover is closed. Alternatively, when it is between the closed position and the open position, the engaging portion of the pressing head abuts against the stopper member and the pressing of the pressing head is restricted. Even if a pressing force is applied to the pressing head by touching the head, the pressing head is not accidentally pressed down. Therefore, it is possible to prevent the contents from being unexpectedly discharged due to the pressing head being erroneously pressed down during the cover rotation operation.

  The container 3 is a resin container, and includes a cylindrical body 3a, a cylindrical mouth 3b concentric with the body 3a, and a shoulder 3c connecting the body 3a and the mouth 3b. It is formed into a shape. The bottom part of the trunk | drum 3a is obstruct | occluded with the lid member 3d, and the inner plate 4 is mounted inside the lid member 3d. The container 3 stores liquid cosmetics such as milky lotion and hairdressing material as contents.

  In the illustrated case, the storage container 3 is a disposable resin container. However, the storage container 3 may be a bottle, a can, or the like, or may be used as a replaceable refill container.

  The pump mechanism P is attached to the mouth portion 3b of the housing container 3 by a mounting cap 5 attached to the mouth portion 3b of the housing container 3 by means such as screwing or undercut engagement. Reference numeral 6 denotes a seal member, which prevents leakage of contents from the mouth portion 3b to which the mounting cap 5 is attached.

  In the present embodiment, as the pump mechanism P, an HVD (High Viscosity Pump-Dispenser) type capable of discharging a liquid having a relatively high viscosity such as an emulsion is used. The pump mechanism P includes a cylinder 11 and a piston guide 12, and a piston 12 a fixed to the piston guide 12 is in sliding contact with the inner surface of the cylinder 11. Further, a spring (not shown) is disposed inside the pump mechanism P, and the piston guide 12 is urged upward in FIG. A stem shaft 13 is fixed to the upper end of the piston guide 12, and a flow path 13 a in the stem shaft 13 communicates with the piston guide 12 and the cylinder 11. A check valve 14 is disposed inside the stem shaft 13.

  A pressing head 20 is fixed to the upper end of the stem shaft 13. The pressing head 20 has a head main body 20a formed in a cylindrical shape with a bottom having a circular cross section, and a fixed cylinder 20b is integrally provided inside the head main body 20a. The lower end portion of the fixed cylinder 20b is connected to the upper end portion of the stem shaft 13 by means such as press fitting, whereby the push-down head 20 is fixed to the stem shaft 13. The fixed cylinder 20b can also be fixed to the stem shaft 13 by other means such as adhesion. On the outer periphery of the head main body 20 a of the pressing head 20, a nozzle 20 c that protrudes outward in the radial direction (a direction perpendicular to the pressing direction of the pressing head 20) is integrally provided. As shown in FIG. 2, the nozzle 20c has a substantially rectangular shape in plan view. As shown in FIG. 1, a discharge hole 20d is provided in the nozzle 20c. The discharge hole 20d communicates with the flow path 13a of the stem shaft 13 through the fixed cylinder 20b.

  1, the pump mechanism P is fixed to the mounting cap 5 by inserting and holding the upper end portion of the cylinder 11 in the U-shaped groove portion of the fixing portion 5a of the mounting cap 5. As shown in FIG. Yes. The stem shaft 13 is in sliding contact with the inner peripheral surface of the fixing portion 5a of the mounting cap 5, and is supported by the fixing portion 5a and is movable in the vertical direction.

It can discharge from the nozzle 20c. When the hand is released from the pressing head 20 after the pressing operation, the pressing head 20 is pushed back together with the piston guide 12 by the spring in the cylinder 11 to return to the initial position. At this time, since the check valve 14 is provided on the stem shaft 13, the content liquid does not flow backward toward the container 3. By repeating the pressing operation and returning of the pressing head 20 as described above, the contents stored in the storage container 3 can be sequentially discharged from the nozzle 20c provided in the pressing head 20 to the outside. .

  When the contents are discharged from the storage container 3 by the pump mechanism P, the inner plate 4 rises as the contents decrease, and even if the contents of the storage container 3 decrease, the contents are pumped by the pump mechanism P. can do. Reference numeral 21 denotes an air hole provided in the lid member 3d so that air flows between the lid member 3d and the middle tray 4 when the middle tray 4 is raised.

  A disc-shaped flange 22 projecting radially outward is integrally provided on the outer periphery of the mounting cap 5 attached to the storage container 3, and a cylindrical shape concentric with the storage container 3 is provided on the outer peripheral edge of the flange 22. The formed cylindrical body 23 is provided integrally. A fixed cylindrical portion 24 is integrally provided at the lower end in the axial direction of the cylindrical body 23 (the end facing downward in FIG. 1). A case body 25 formed in a bottomed cylindrical shape by a resin material, a metal material or the like is fixed to the fixed cylinder portion 24 by fixing means such as screwing or undercut engagement at the opening end 25a. The case body 25 is accommodated inside.

  In the present embodiment, the cylindrical body 23 is formed integrally with the mounting cap 5 and attached to the receiving container 3 together with the mounting cap 5, but the cylindrical body 23 is formed separately from the mounting cap 5. And it can also be set as the structure attached to the storage container 3 by attachment means, such as screwing, press fit, and undercut engagement.

  The discharge container 1 includes a cover 30 that can cover the outer periphery of the push-down head 20 in order to prevent the push-down head 20 from being accidentally pushed down during distribution or when not in use.

  The cover 30 has a cover main body 31, which is longer in the axial direction than the cylindrical body 23 and is formed in a substantially cylindrical shape having a larger diameter than the cylindrical body 23 and the case body 25. . The cover body 31 is mounted on the outer peripheral side of the cylindrical body 23 coaxially with the cylindrical body 23, covers the outer periphery of the push-down head 20, the upper half of the cylindrical body 23 and the case body 25, and the cylindrical body 23 and the case body 25. On the other hand, it is relatively movable in the axial direction and relatively rotatable around the axis. An annular wall 32 constituting a top surface parallel to the top surface of the pressing head 20 is integrally provided at one end in the axial direction on the upper side in FIG. As shown in FIG. 2, the annular wall 32 has an annular shape having a circular hole 32a corresponding to the shape of the head main body 20a of the push-down head 20, and a part of the inner periphery of the circular hole 32a. Is provided with an arcuate recess 32b which becomes a relief portion of the nozzle 20c of the pressing head 20.

  As shown in FIGS. 1 and 3, a cylindrical insert 33 is fixed inside the cover body 31. The insertion body 33 abuts against the inner surface of the annular wall 32 of the cover 30 in the axial direction, is positioned in the axial direction with respect to the cover body 31, and is prevented from rotating with respect to the cover body 31 by a rotation preventing portion 34. As shown in FIGS. 3 and 4, for example, the anti-rotation portion 34 includes a spline 34 a formed on the inner peripheral surface of the cover body 31 along the axial direction, and an outer peripheral surface of the insert 33 along the axial direction. Although spline fitting by engagement with the formed spline groove 34b can be performed, the spline groove 34b may be provided on the inner peripheral surface of the cover body 31 and the spline 34a may be provided on the outer peripheral surface of the insert 33. it can.

  The cover body 31 and the insert 33 can be formed of, for example, a resin material, but can be formed of other materials such as a metal material.

  A conversion mechanism 40 is provided between the cylindrical body 23 and the cover 30. The conversion mechanism 40 converts the displacement of the cover 30 in the rotational direction around the axial center with respect to the cylindrical body 23 into the displacement of the cover 30 in the axial direction with respect to the cylindrical body 23.

  As shown in FIGS. 3 and 5, the conversion mechanism 40 includes a spiral groove 41 provided on the outer peripheral surface of the cylindrical body 23 and a protrusion 42 provided integrally on the inner peripheral surface of the insertion body 33 of the cover 30. Yes. The spiral groove 41 extends in the circumferential direction on the outer peripheral surface of the cylindrical body 23 at a constant lead angle, and holding grooves 43a and 43b extending along the circumferential direction of the cylindrical body 23 are connected to both ends thereof. . On the other hand, the protrusion 42 is formed in a circular boss shape that protrudes radially inward from the inner peripheral surface of the insertion body 33, and its outer diameter is slightly smaller than the width of the spiral groove 41. The protrusion 42 is disposed inside the spiral groove 41 and can move along the spiral groove 41 between one holding groove 43a and the other holding groove 43b.

  When the cover 30 is in the closed position, the protrusion 42 is on one end side of the spiral groove 41 and is engaged with the holding groove 43a as shown in FIG. In addition, by engaging the protrusion 42 with the holding groove 43a, it is possible to prevent the cover 30 from being opened due to the protrusion 42 moving along the spiral groove 41 by its own weight. From this state, when the cover 30 is rotated relative to the cylindrical body 23 in the counterclockwise direction in FIG. 2, the protrusion 42 moves along the spiral groove 41, and the cover 30 moves relative to the cylindrical body 23 in FIG. 1. It moves relative to the axial direction downward. Then, when the projection 42 reaches the other end of the spiral groove 41 and engages with the holding groove 43b on the other end side as shown in FIG. 10, the cover 30 opens to expose the pressing head 20 as shown in FIG. Position. Thus, by rotating the cover 30, the cover 30 can be opened and closed in the axial direction between the closed position that covers the outer periphery of the pressing head 20 and the open position that exposes the pressing head 20. it can.

  Although only one conversion mechanism 40 is shown in FIG. 1, a pair of conversion mechanisms 40 can be provided at point-symmetrical positions around the axis of the cylindrical body 23.

  As shown in FIG. 1, a stopper member 50 is provided in the discharge container 1 in order to prevent the pressing head 20 from being accidentally pressed down during the rotation operation of the cover 30. As shown in FIGS. 3 and 4, the stopper member 50 includes a cylindrical portion 50a and an annular large portion extending radially outward from one end in the axial direction on the side of the pressing head 20 of the cylindrical portion 50a. A radial flange portion 50b and an annular small-diameter flange portion 50c extending radially inward from the other axial end of the cylindrical portion 50a are provided.

  As shown in FIG. 3, the axial end surface of the flange 22 provided on the mounting cap 5 facing the pressing head 20 is a support surface 51, and the stopper member 50 is placed on the support surface 51 in the small-diameter flange portion 50c. Is arranged. Further, the stopper member 50 is in sliding contact with the inner peripheral surface of the cylindrical body 23 at the outer peripheral surface of the cylindrical portion 50a, so that the stopper member 50 is rotatable relative to the support surface 51 around its axis. It has become.

  As shown in FIG. 3, a detent portion 52 is provided between the outer peripheral surface of the large-diameter flange portion 50 b and the inner peripheral surface of the insert body 33 of the cover 30. 50 rotates integrally with the cover 30 around the axis. As shown in FIG. 4, the anti-rotation portion 52 includes a spline 52 a formed along the axial direction on the outer peripheral surface of the large-diameter flange portion 50 b of the stopper member 50, and an axial direction on the inner peripheral surface of the insertion body 33. The spline fitting can be performed by meshing with the spline groove 52b formed along, but the spline 34a is provided on the inner peripheral surface of the inner layer body 33 and the spline groove 34b is provided on the outer peripheral surface of the large-diameter flange portion 50b. You can also Further, since the rotation preventing portion 52 is spline-fitted, the stopper member 50 is movable relative to the cover 30 in the axial direction. That is, the cover 30 can move relative to the stopper member 50 disposed on the support surface 51 in the axial direction. Thus, the stopper member 50 is connected to the cover 30 so as to be relatively movable in the axial direction and rotate integrally with the rotation stopper 52.

  As shown in FIGS. 3 and 4, the stopper member 50 is provided with a pair of stopper walls 50 d. These stopper walls 50d are formed in an arc shape extending in a predetermined angle range along the circumferential direction of the small-diameter flange portion 50c, are erected in the axial direction from the small-diameter flange portion 50c, and are more than the large-diameter flange portion 50b. It protrudes in the axial direction toward the pressing head 20. The pair of stopper walls 50d are disposed at point-symmetrical positions around the axis of the cylindrical body 23.

  A cylindrical portion 53 having a smaller diameter than the stopper wall 50d and capable of being inserted inside the stopper wall 50d is integrally provided on the lower surface of the pressing head 20, and the outer peripheral surface of the cylindrical portion 53 corresponds to the stopper wall 50d. Thus, a pair of vertical ribs (engagement portions) 54 are provided at point-symmetric positions about the axis. Each of the vertical ribs 54 protrudes radially outward from the outer peripheral surface of the cylindrical portion 53 and extends along the axial direction, and when the cover 30 is in the closed position or between the closed position and the open position. Further, the lower end facing the support surface 51 is in contact with the upper end of the stopper wall 50d of the stopper member 50 facing the pressing head 20 from the axial direction.

  The support surface 51 of the flange 22 is integrally provided with a non-rotating cylindrical wall 55 that protrudes from the support surface 51 toward the pressing head 20 on the radially inner side of the stopper member 50. The non-rotating cylindrical wall 55 has a groove portion 55 a, and this groove portion 55 a is engaged with a non-rotating projection 53 a provided on the inner peripheral surface of the cylindrical portion 53 of the push-down head 20. As a result, the pressing head 20 is prevented from rotating with respect to the cylindrical body 23. As described above, by using the cylindrical portion 53 for providing the vertical ribs 54 that come into contact with the stopper member 50 to prevent the pressing head 20 from rotating around the cylindrical body 23, the configuration of the rotation stopper is simplified. be able to.

  Next, the usage method of the discharge container 1 of such a structure is demonstrated.

  During distribution or when not in use, the cover 30 is placed in the closed position shown in FIG. 1, that is, in the closed state, so that the outer periphery of the pressing head 20 is covered with the cover 30 so that the pressing head 20 cannot be pressed. it can. That is, when the cover 30 is in the closed position, the top surface of the pressing head 20 and the top surface of the cover 30 are the same surface, and the outer periphery of the pressing head 20 is covered by the cover 30. No. 20 is in a state where it cannot be pushed down. Therefore, by setting the cover 30 to the closed position (closed state), it is possible to prevent the contents from being unexpectedly discharged from the storage container 3 due to the pressing head 20 being erroneously pressed down.

  Next, when using the discharge container 1, the cover 30 is rotated to rotate the cover 30 relative to the storage container 3. When the cover 30 is rotated, the cover 30 is moved from the closed position to the open position by the conversion mechanism 40, and the push-down head 20 is exposed from the cover 30 to be in a state where the push-down operation is possible. At this time, as shown in FIGS. 2 and 7, the nozzle 20 c of the pressing head 20 moves along the recess 32 b of the annular wall 32 of the cover 30 as the cover 30 rotates.

  Here, when the cover 30 is in the closed position, or when the cover 30 is rotated and located between the closed position and the open position, as shown in FIGS. 3 and 4, the push head 20 is provided. The lower end surface of the vertical rib 54 comes into contact with the upper end surface of the stopper wall 50d of the stopper member 50 in the axial direction, and the pressing head 20 is supported by the support surface 51 via the stopper member 50. As a result, the pressing of the pressing head 20 toward the container 3 is restricted by the stopper member 50.

  Therefore, even when a load in the pressing direction is applied to the pressing head 20 when the cover 30 is in the closed position, the pressing head 20 is not pressed down. Further, even when a load in the pressing direction is accidentally applied to the pressing head 20 protruding from the top surface of the cover 30 during the rotation operation of the cover 30, the pressing head 20 is not pressed down. Thus, when the cover 30 is in the closed position or between the closed position and the open position, that is, at a position other than the open position, the lower end surface of the vertical rib 54 contacts the upper end surface of the stopper wall 50d of the stopper member 50 from the axial direction. Since the pressing of the pressing head 20 is restricted by the stopper member 50, it is prevented that the contents are discharged from the receiving container 3 by being accidentally pressed by the pressing head 20 during the rotation operation of the cover 30. Is done.

  As shown in FIG. 6, when the cover 30 moves to the open position, the pressing head 20 protrudes from the top surface of the cover 30 and is exposed to the outside. When the cover 30 is in the open position, the stopper wall 50d of the stopper member 50 is shifted in the circumferential direction with respect to the vertical rib 54 of the pressing head 20, as shown in FIGS. 54 can move toward the support surface 51 side without contacting the stopper wall 50d until it contacts the small diameter flange portion 50c along the inside of the cylindrical portion 50a. Therefore, when the cover 30 is in the open position, the push-down head 20 can be pushed down, and the push-down head 20 can be pushed down from the position indicated by the two-dot chain line in FIG. 6 to the position indicated by the solid line. it can. Then, the pump mechanism P can be pumped by pushing down the push-down head 20, and the contents inside the container 3 can be discharged from the nozzle 20c.

  After the discharge container 1 is used, when the cover 30 is rotated clockwise from the state shown in FIG. 7 in order to return the cover 30 from the open position to the closed position, the stopper wall 50d of the stopper member 50 rotates together with the cover 30. Then, it moves below the vertical rib 54 of the pressing head 20, and the vertical rib 54 comes into contact with the stopper wall 50d of the stopper member 50 from the axial direction again. Thereby, the pressing of the pressing head 20 is regulated by the stopper member 50. Accordingly, even when the cover 30 is rotated from the open position toward the closed position, the pressing of the pressing head 20 is restricted by the stopper member 50 during the rotating operation, and the pressing head 20 is erroneously pressed down. Is prevented.

  As described above, in the discharge container 1 of the present invention, when the cover 30 is in the closed position or between the closed position and the open position, that is, in a position other than the open position, the vertical rib 54 provided on the pressing head 20 is the stopper member. Since the pressing of the pressing head 20 is restricted by coming into contact with the 50 stopper walls 50d in the axial direction, it is possible to prevent the pressing head 20 from being erroneously pressed down during the rotation operation of the cover 30. Therefore, it is possible to prevent the contents inside the storage container 3 from being accidentally discharged due to the pressing head 20 being accidentally pressed down during the rotation operation of the cover 30.

  On the other hand, when the cover 30 is in the open position, the stopper wall 50d of the stopper member 50 is displaced in the circumferential direction with respect to the vertical rib 54 provided on the pressing head 20, and the pressing head 20 can be pressed down. The contents stored in the storage container 3 can be discharged from the nozzle 20 c of the pressing head 20 by the pressing operation of the head 20. Therefore, by rotating the cover 30 to the open position, it is possible to make the pressing head 20 in a state where the pressing head 20 can be pressed without performing another switching operation or the like.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, although the HVD type pump mechanism P is used as the pump mechanism P in the above-described embodiment, the present invention is not limited to this, and foam generation is possible as long as the contents stored in the storage container 3 can be discharged. Other pump mechanisms such as a pump mechanism configured in a discharger or a spray discharger can also be used.

  Moreover, in the said embodiment, although the thing provided with the pump mechanism P as the container main body 2 is used, not only this but the content is discharged from the storage container 3 by pushing down operation of the pushing-down head 20. As long as it can be used, for example, a container body having another structure such as an aerosol spray can be used.

  Furthermore, the contents to be stored in the storage container 3 are not limited to liquid cosmetics such as milky lotion and hair styling, but may be various things such as shampoos and creams.

  Furthermore, in the embodiment, the conversion mechanism 40 has a structure in which the spiral groove 41 is provided on the outer peripheral surface of the cylindrical body 23 and the protrusion 42 is provided on the inner peripheral surface of the insert 33 of the cover 30. The protrusion 42 may be provided on the outer peripheral surface of the cylindrical body 23, and the spiral groove 41 may be provided on the inner peripheral surface of the insert body 33 of the cover 30.

  Furthermore, in the above-described embodiment, the spiral groove 41 has a uniform shape between one end whose lead angle corresponds to the closed position and the other end corresponding to the open position. If the spiral groove 41 is formed in a curve that rotates and rises in a direction perpendicular to the rotation surface, the lead angle changes between one end corresponding to the closed position and the other end corresponding to the open position.
