And in this exposure position, the pressing head is operated to discharge the contents in the container body.

JP 2003-020085 A

  However, in the above-described conventional discharge container, for example, when the head cover rotates about the container axis with respect to the container body due to unexpected external force or mischief, the head cover moves unexpectedly from the covering position to the exposed position. There is a fear. For this reason, there is room for improvement in that the movement of the head cover to the exposed position with respect to the container main body is reliably restricted at the covering position.

  The present invention has been made in view of such circumstances, and in the initial state where the head cover is in the covering position and the locking portion is locked to the locked portion, the head cover is exposed to the exposed position of the container body. An object of the present invention is to provide a discharge container that can reliably regulate the movement of the liquid.

In order to solve the above problems, the present invention proposes the following means.
A discharge container according to the present invention includes a container main body in which contents are stored, a stem disposed in an upwardly biased state so as to be movable downward, and a pressing head formed with a discharge hole communicating with the stem. The discharge body, the exterior body covered with the container body, and the pressing head from outside in the radial direction, and the pressing head is passed to a position facing the pressing head in the container axial direction to the outside. A head cover formed with a projecting passage hole; and disposed between the exterior body and the head cover; and with the relative rotation of the exterior body and the head cover along a container axis, Relative to the head cover in the container axial direction between a covering position where the pressing head is surrounded by the head cover and an exposed position where the pressing head protrudes outside through the passage hole An operating piece supported to be elastically displaceable with respect to the head cover, and the operating piece is locked to a locked portion of the exterior body. A locking portion that restricts movement of the head cover relative to the exterior body, and an operation portion that elastically displaces the operation piece toward a release position where the locking of the locking portion and the locked portion is released. It is characterized by providing.

According to this configuration, since the locking portion and the locked portion are locked at the covering position, the movement of the head cover relative to the exterior body is restricted. On the other hand, the head cover is allowed to move relative to the exterior body by operating the operation unit and maintaining the operation piece at the release position. In this state, the exterior body and the head cover are moved relative to each other along the guide portion, so that the exterior body and the head cover can be moved toward the exposure position. Specifically, as the head cover and the exterior body move relative to each other, the head cover and the exterior body move relative to each other along the container axis direction, so that the pressing head protrudes outside through the passage hole of the head cover. It becomes.
In this way, for example, the head cover is prevented from rotating unexpectedly around the container axis with respect to the exterior body due to, for example, unexpected external force or mischief, the head cover is in the covering position, and the locking portion is locked to the locked portion. In the locked initial state, the movement of the head cover to the exposed position with respect to the exterior body can be reliably restricted.

Further, a rib extending along the container axial direction is formed on the outer peripheral surface of the container main body, and the outer body contains the rib, and the container body and the outer body move relative to each other around the container axis. A slit that regulates the angle may be formed, and the locked portion may be formed between the rib and the slit along the container axial direction.
In this case, since the movement of the exterior body around the container axis with respect to the container body is restricted, it is possible to prevent the head cover and the exterior body from rotating together with respect to the container body when the head cover is operated.
And since the to-be-latched part is formed between the slit of an exterior body and the rib of a container main body, it is not necessary to form a to-be-latched part separately from a slit. Thereby, simplification of a structure can be achieved.

The guide portion is disposed on one side of the head cover and the exterior body, and is disposed on the other side of the head cover and the exterior body, and a groove extending spirally around the container axis. And a protrusion that moves in the groove, and positions of the protrusion, the locking portion, and the locked portion along the circumferential direction may coincide with each other.
In this case, since the positions along the circumferential direction of the protrusion, the locking portion, and the locked portion coincide with each other, the head cover is rotated through the operation piece while the operation piece is maintained at the release position. When the moving operation is performed, the force can be efficiently transmitted to the protrusion, and the head cover can be efficiently moved along the guide portion.

  According to the discharge container of the present invention, the head cover is prevented from rotating unexpectedly around the container axis with respect to the exterior body due to, for example, unexpected external force or mischief, and in the initial state described above, the head cover for the exterior body The movement to the exposure position can be reliably regulated.

Specifically, the shoulder portion 12 includes an upper step portion 15 projecting radially outward from the lower end edge of the mouth portion 11, and an upper tube portion extending downward from the outer peripheral edge of the upper step portion 15. 16, a lower cylinder part 17 that is connected from the lower end edge of the upper cylinder part 16 and has a larger diameter than the upper cylinder part 16, and a lower step part 18 that connects the lower end edge of the lower cylinder part 17 and the body part 13. And have.

The upper cylinder portion 16 is formed with an engagement protrusion 21 that protrudes outward in the radial direction. Note that the engagement protrusion 21 may be formed over the entire circumference of the upper tube portion 16 or may be formed intermittently in the circumferential direction.
The lower cylinder portion 17 is formed with a rib 22 that protrudes outward in the radial direction and extends along the container axis O direction. The rib 22 has a lower end edge connected to the upper end edge of the shoulder portion 12, while the upper end edge is located below the upper end edge of the lower cylinder portion 17. In the illustrated example, the ribs 22 are provided as a pair at positions opposed in one direction in the radial direction.

  The discharger 3 is a pump-type discharger 3 that discharges contents using a pump, for example, and can be moved downward in an upward biased state with a mounting cap 31 mounted on the mouth 11 of the container body 2. A discharger main body 33 having a stem 32 disposed on the top of the stem 32, and a crested cylindrical pressing head 34 attached to the upper end of the stem 32.

The mounting cap 31 includes a cap-shaped cap body 41 that is screwed into the mouth portion 11, and a guide tube 42 that extends upward from the top wall portion of the cap body 41.
The top wall portion of the cap body 41 is formed in an annular shape and is disposed on the upper end edge of the mouth portion 11 with the packing 43 interposed therebetween. The radially inner end portion of the top wall portion is located on the radially inner side with respect to the mouth portion 11, and a cylinder 51 (described later) of the discharger main body 33 is connected thereto. The cap body 41 may be attached to the mouth portion 11 by undercut fitting or the like.
The guide cylinder 42 guides the movement of the pressing head 34 along the container axis O direction on the inner side.

The discharger main body 33 includes a cylinder 51 integrally formed with the mounting cap 31 described above, the above-described stem 32 projecting upward from the cylinder 51, and the inside communicating with the inside of the cylinder 51. And a piston (not shown) linked to the stem 32 and a biasing member 54 that biases the stem 32 and the piston upward.
The cylinder 51 has a lower end side communicating with the inside of the container body 2 via the suction cylinder 52 and an upper end side communicating with the inside of the pressing head 34 via the stem 32. The cylinder 51 may be provided separately from the mounting cap 31.

  The pressing head 34 is formed in a cylindrical shape with a top, and a discharge hole 34 a that opens outward in the radial direction is formed in the peripheral wall portion. In addition, a flow passage 53 that connects the discharge hole 34 a and the inside of the stem 32 is formed inside the pressing head 34.

  The exterior body 4 surrounds the upper cylinder part 16 and the lower cylinder part 17 from the outer side in the radial direction among the shoulder parts 12 of the container body 2. On the inner peripheral surface of the exterior body 4, an engagement protrusion 61 that protrudes inward in the radial direction is formed. The engagement protrusion 61 is undercut fitted to the engagement protrusion 21 of the container main body 2 described above, and restricts relative movement of the container main body 2 and the exterior body 4 along the container axis O direction. In the illustrated example, the outer diameter of the exterior body 4 is larger than the outer diameter of the body portion 13.

As shown in FIG. 3, the exterior body 4 is formed with slits 62 extending along the container axis O direction at positions facing in one direction described above in the radial direction. Each slit 62 penetrates in the radial direction and opens at the lower end edge of the exterior body 4, and the above-described ribs 22 are individually fitted therein. Thereby, the relative movement along the circumferential direction of the exterior body 4 and the container main body 2 is regulated.
The slit 62 is longer in the container axis O direction than the rib 22, and a gap extending in the container axis O direction is formed between the upper end edge of the rib 22 and the upper end edge of the slit 62. ing. This gap functions as a locked portion 63 to which a locking portion 75 described later is locked.

  As shown in FIGS. 1 and 2, the head cover 5 surrounds the shoulder 12 of the container body 2 and the discharge device 3 from the outside in the radial direction, and the upper portion is reduced in diameter relative to the lower portion. It is said that. A portion of the head cover 5 located above the pressing head 34 described above is open along the container axis O direction, and constitutes a passage hole 71 through which the pressing head 34 passes and protrudes to the outside. In the illustrated example, the inner diameter of the passage hole 71 is larger than that of the guide cylinder 42 of the discharger 3.

  The head cover 5 is formed with a pair of recesses 72 that are opened downward at positions facing each other in the above-described one direction in the radial direction. In each recess 72, operation pieces 74 are housed separately. As shown in FIG. 2, the operation piece 74 has both peripheral edges connected to a pair of side surfaces facing each other in the circumferential direction among the inner peripheral surfaces of the recess 72 via elastic hinges 73. .

  As shown in FIGS. 1 and 2, each operation piece 74 has a plate shape extending in the container axis O direction in a side view as viewed from the radial direction, and a lower portion thereof is directed downward from a lower end edge of the head cover 5. Protruding. The operation piece 74 is configured to be elastically displaced by elastic deformation of the elastic hinge portion 73. In the illustrated example, the operation piece 74 rotates around a hinge axis C extending along the circumferential direction.

At the upper end portion of the operation piece 74, a locking portion 75 that protrudes inward in the radial direction is formed. The locking portion 75 is locked in the locked portion 63 of the exterior body 4 described above, thereby restricting movement of the head cover 5 relative to the exterior body 4 in the container axis O direction and the circumferential direction.
On the other hand, a portion of the operation piece 74 that protrudes below the lower end edge of the head cover 5 is locked by the locking portion 75 from the locking position where the locking portion 75 is locked by the locked portion 63. An operation portion 76 for operating the operation piece 74 around the hinge axis C toward the release position (see FIG. 4) where it is detached from the portion 63 is configured.

  Here, between the exterior body 4 and the head cover 5, the exterior body 4 and the head cover 5 are moved in the direction of the container axis O along with the relative rotation of the exterior body 4 and the head cover 5 around the container axis O. A guide portion 81 that is supported so as to be capable of relative movement is provided.

The guide portion 81 is disposed on the exterior body 4 and has a pair of grooves 82 that spirally extend along the circumferential direction, and a pair of protrusions that are disposed on the head cover 5 and slide in the grooves 82. 83.
As shown in FIG. 3, each groove 82 extends downward toward the one side in the circumferential direction on the outer peripheral surface of the exterior body 4, and its upper end portion 82 a is above each slit 62. The lower end portion 82b (see FIG. 2) is located at a portion of the lower end portion of the outer package 4 that is spaced apart from the upper end portion 82a in the circumferential direction. In the illustrated example, the upper end portion 82a and the lower end portion 82b of each groove 82 are spaced apart by, for example, about 90 ° in the circumferential direction.
Therefore, the upper end portion 82a of each groove 82 is opposed in one direction described above in the radial direction, while the lower end portion 82b is opposed in another direction orthogonal to the one direction described above. Of the inner peripheral surface of the upper end portion 82a, the lower surface is a flat surface extending in the circumferential direction.

  A vertical groove 85 extending upward is formed at the upper end portion 82a of each groove 82. Each vertical groove 85 has a lower end communicating with the groove 82, and an upper end opened upward at the upper edge of the exterior body 4. Of each longitudinal groove 85, the inner peripheral surface located on one side in the circumferential direction is a tapered surface that inclines toward one side in the circumferential direction toward the outer side in the radial direction.

  As shown in FIGS. 1 and 2, the projecting portion 83 projects radially inward from a portion of the inner peripheral surface of the head cover 5 located above the locking portion 75 described above. The protrusion 83 is accommodated in the groove 82 through the vertical groove 85 described above. The vertical groove 85 described above is formed with a restricting protrusion 86 that protrudes outward in the radial direction, and the upward movement of the protrusion 83 is restricted.

  The guide portion 81 of this embodiment includes a covering position where the pressing head 34 is surrounded from the outside in the radial direction by the head cover 5 and an exposed position where the pressing head 34 protrudes outside through the passage hole 71 of the head cover 5 (FIG. 5). The relative movement of the head cover 5 with respect to the exterior body 4 and the container main body 2 is guided between them. In the covering position of the head cover 5 described above, the protruding portion 83 of the guide portion 81, the locking portion 75, and the locked portion 63 are aligned in the circumferential direction.

Next, the operation of the above-described discharge container 1 will be described. In the following description, the state in which the head cover 5 is in the above-described covering position and the operation piece 74 is in the locking position as shown in FIGS. 1 and 2 is the initial state of the discharge container 1.
As shown in FIG. 4, when using the discharge container 1, first, the operation unit 76 of each operation piece 74 is gripped by a finger or the like, and each operation unit 76 is pressed toward the inside in the radial direction. Then, the operation piece 74 moves from the locking position toward the release position by being elastically displaced about the hinge axis C by elastic deformation of the elastic hinge portion 73. Specifically, when the locking portion 75 of the operation piece 74 moves outward in the radial direction, the locking portion 75 is detached from the locked portion 63 of the exterior body 4. Thereby, the movement of the head cover 5 in the container axis O direction and the circumferential direction with respect to the exterior body 4 is allowed.

  Then, the exterior body 4 and the head cover 5 are relatively rotated toward one side in the circumferential direction while the operation piece 74 is maintained at the release position. Then, as shown in FIGS. 5 and 6, the head cover 5 is guided by the guide portion 81 from the covering position toward the exposed position. Specifically, the protrusion 83 slides in the groove portion 82 of the exterior body 4 from the upper end portion 82a toward the lower end portion 82b, so that the relative rotation between the head cover 5, the exterior body 4 and the container body 2 is achieved. With the moving operation, the head cover 5 moves downward with respect to the exterior body 4 and the container body 2.

Thereby, the pressing head 34 becomes an exposed position that protrudes upward from the head cover 5 through the passage hole 71 of the head cover 5. The protrusion 83 abuts against the inner surface of the lower end portion 82 b of the groove 82, so that further movement of the head cover 5 with respect to the container body 2 and the exterior body 4 is restricted.
Thereafter, when the pressing of the operating portion 76 on the operating piece 74 is released, the operating piece 74 is elastically displaced around the hinge axis C along with the restoration of the elastic hinge portion 73, so that the locking portion 75 has a diameter on the trunk portion 13 of the container body 2. Contact from the outside in the direction. Note that the operation piece 74 does not need to continue to press the operation portion 76 until the projection 83 reaches the lower end portion 82b, and at least until the circumferential position of the locking portion 75 and the locked portion 63 is shifted. If 76 is pressed, the pressing may be released thereafter.

  Then, with the head cover 5 in the exposed position, the stem 32 is pushed down by the push-down operation of the push-down head 34, and the contents in the container body 2 are sucked into the discharger body 33 through the suction cylinder 52. The content sucked into the discharger main body 33 flows into the flow passage 53 of the pressing head 34 through the stem 32, and is then discharged outward through the discharge hole 34a.

In order to return the discharge container 1 to the initial state after the discharge container 1 is used, first, the exterior body 4 and the head cover 5 are relatively rotated toward the other side in the circumferential direction. Then, the head cover 5 is guided by the guide portion 81 from the exposed position toward the covering position. Specifically, the protrusion 83 slides in the groove portion 82 of the exterior body 4 from the lower end portion 82 b toward the upper end portion 82 a, so that the relative rotation between the head cover 5, the container body 2, and the exterior body 4 is performed. With the moving operation, the head cover 5 moves upward with respect to the exterior body 4 and the container body 2.
Accordingly, the pressing head 34 is retracted from the passage hole 71 of the head cover 5 and becomes a covering position surrounded by the head cover 5. The protrusion 83 abuts against the inner surface of the upper end portion 82 a of the groove 82, so that further movement of the head cover 5 with respect to the container body 2 and the exterior body 4 is restricted.

In the process in which the head cover 5 moves from the protruding position to the covering position, the locking portion 75 of the operation piece 74 is parallel to the protruding portion 83 of the head cover 5 while sliding on the outer peripheral surface of the body portion 13 and the exterior body 4. Move to. At this time, since the outer diameter of the exterior body 4 is larger than the outer diameter of the body portion 13 as described above, when the locking portion 75 reaches the exterior body 4, the operation piece 74 is moved around the hinge axis C. It is elastically displaced toward the release position side along.
Thereafter, the operating piece 74 is elastically displaced, the locking portion 75 slides on the outer peripheral surface of the exterior body 4, and when the locking portion 75 reaches the locked portion 63, It is elastically displaced toward the locking position by restoring deformation. Thereby, the locking part 75 is locked in the locked part 63. That is, in the present embodiment, the locking portion 75 is automatically locked to the locked portion 63 without operating the operating portion 76 in the process of moving the head cover 5 from the protruding position to the covering position. It has become.
Thus, the discharge container 1 returns to the initial state.

Thus, in this embodiment, since the locking part 75 and the locked part 63 are locked at the covering position, the relative movement along the guide part 81 between the exterior body 4 and the head cover 5 is restricted. Is done. On the other hand, the exterior body 4 and the head cover 5 are relatively moved along the guide portion 81 in a state where the operation piece 74 is maintained at the release position where the locking of the locking portion 75 and the locked portion 63 is released. Thus, the exterior body 4 and the head cover 5 can be moved toward the exposure position.
Thereby, for example, the head cover 5 is prevented from rotating unexpectedly around the container axis O with respect to the exterior body 4 due to external force or mischief, and the head cover 5 is moved relative to the exterior body 4 to the exposed position in the initial state. It can be regulated reliably.

  Moreover, since the surface located below among the inner peripheral surfaces of the upper end portion 82a in the groove portion 82 is a flat surface extending along the circumferential direction, an external force acts on the head cover 5 downward. Furthermore, it is possible to prevent the protrusion 83 from sliding unexpectedly in the groove 82 and the head cover 5 from rotating relative to the exterior body 4. Thereby, the movement to the exposure position of the head cover 5 with respect to the exterior body 4 in an initial state can be controlled reliably.

Further, since the rib 22 of the container body 2 is fitted in the slit 62 of the exterior body 4, the movement of the exterior body 4 around the container axis O with respect to the container body 2 is restricted. 2 can prevent the head cover 5 and the exterior body 4 from rotating together.
In addition, since the locked portion 63 is formed between the slit 62 of the exterior body 4 and the rib 22 of the container body 2, it is not necessary to form the locked portion 63 separately from the slit 62. Thereby, simplification of a structure can be achieved.

Further, since the slit 62 is opened at the lower end edge of the exterior body 4, the mold can be easily removed during molding of the exterior body 4, and complexity of the mold structure can be suppressed. Thereby, the exterior body 4 can be formed easily and the improvement of manufacturing efficiency can be aimed at.
Moreover, by opening the slit 62 at the lower end edge of the exterior body 4, the mold having the portion for forming the slit 62 can be moved in the container axis O direction when the mold is opened. Accordingly, since the draft angle in the radial direction is not taken into consideration, the inner peripheral surface of the slit 62 can be a flat surface extending in the radial direction, and the rib 22 and the slit 62 can be reliably fitted. can do.

  Moreover, in the covering position mentioned above, since the positions along the circumferential direction of the protrusion 83, the locking portion 75, and the locked portion 63 coincide with each other, the operation piece 74 is maintained in the release position. When the head cover 5 is rotated via the operation piece 74, the force can be efficiently transmitted to the protrusion 83, and the head cover 5 can be efficiently moved along the guide portion 81. it can.

Alternatively, the protrusion 83 may be formed, and the groove 82 may be formed on the head cover 5 side.
In the above-described embodiment, the configuration in which the protrusion 83 slides in the groove portion 82 has been described. However, the present invention is not limited thereto, and any configuration may be used as long as the protrusion 83 moves in the groove portion 82.
Furthermore, although embodiment mentioned above demonstrated the structure where the outer diameter of the exterior body 4 is larger than the container main body 2, it is not restricted to this.

Further, the design range of the groove 82 can be changed as appropriate.
Further, in the above-described embodiment, the concave and convex shapes may be formed in reverse by the locked portion 63 of the exterior body 4 and the locking portion 75 of the operation piece 74.

Moreover, although the case where the pump-type discharge device 3 was employ | adopted as the discharge device 3 mentioned above was demonstrated, it is not restricted to this. For example, an aerosol type dispenser may be employed.
In the above-described embodiment, the configuration in which the exterior body 4 surrounds only the shoulder portion 12 of the container body 2 has been described. However, the present invention is not limited thereto, and the body portion 13 and the like may be surrounded.
Furthermore, although embodiment mentioned above demonstrated the case where the head cover 5 was formed in the cylinder shape, it is not restricted to this. That is, the design of the shape of the head cover 5 can be changed as appropriate as long as the passage hole 71 for projecting the pressing head 34 to the outside is formed at a position facing the pressing head 34 in the container axis O direction.
