Description

The present invention relates to a double container and the outer container.

  In general, a double container is known in which an inner container can be stored inside an outer container. Since this double container can exchange the inner container with respect to the outer container, the outer container can be reused. Therefore, it is only necessary to improve the appearance with respect to the outer container seen from the outside, and the inner container installed becomes a refill container to be discarded. For this reason, the inner container can reduce the amount of the container and can reduce the load on the global environment.

  A dispenser container will be described as an example of a conventional double container. Many conventional double-container-type dispenser containers have a structure in which when a dispenser (quantitative discharge pump) is attached to an outer container by screwing, the inner container is also fixed to the outer container by this screwing force (see Patent Document 1). .

  When exchanging the inner container in this dispenser container, the dispenser is first turned to remove the dispenser from the outer container. As a result, the inner container becomes removable from the outer container, and the used inner container is removed from the outer container and discarded.

  Subsequently, after removing the cap provided on the new inner container, the inner container is mounted in the outer container, and the dispenser is screwed to the outer container. As described above, the replacement process of the inner container with respect to the outer container has been performed.

JP 2008-189315 A

  However, in the conventional double container, the inner container rotates relative to the outer container only by mounting a new inner container on the outer container. For this reason, it is necessary to attach and detach the dispenser while preventing rotation of each container at the time of replacement. For this reason, the conventional double container has a problem that the replacement process of the inner container is troublesome and the operability is poor.

The present invention has been made in view of the above, and an object thereof is to provide a double container and outer container with improved operability at the time of exchange of the inner container.

From the first point of view, the above problem is

  Next, embodiments of the present invention will be described with reference to the drawings.

1 to 6 are views for explaining a double container 10A according to the first embodiment of the present invention. The double container 10A according to the present embodiment includes an outer container 11, an inner container 12, an attachment / detachment mechanism 13A , and the like.

  In this embodiment, a cosmetic container is described as an example of the double container 10A. However, the application of the present invention is not limited to a cosmetic container, and can be applied to other containers. In each figure, the direction indicated by the arrow Z1 is the mounting direction, and the direction indicated by the arrow Z2 is the separation direction.

  The outer container 11 has a substantially cylindrical shape, and is formed of resin in this embodiment. The material of the outer container 11 is not limited to resin, and other materials (for example, glass, ceramics, etc.) can be used.

  The outer container 11 has a configuration in which an attaching / detaching mechanism 13A is provided in the outer container main body 11a. The outer container main body 11 a has a lid part 14 and a cylindrical part 16.

  The lid portion 14 is disposed on the upper portion of the cylindrical portion 16. The cylindrical portion 16 has a substantially cylindrical shape, and in the present embodiment, the lower end portion is opened to form a bottom opening 17.

  An inner container 12 to be described later is mounted in the cylindrical portion 16 from the bottom opening 17. In the present embodiment, the bottom opening 17 is formed at the lower end of the tubular portion 16, but a bottom lid for closing the bottom opening 17 may be provided.

  Further, unlike the inner container 12 that functions as a refill container, the cylindrical part 16 is used for a long time without being discarded. For this reason, the cylindrical part 16 is good also as a structure which gave the design for improving an external appearance in the outer peripheral part.

  The lid portion 14 has a circular upper opening 18 formed in the upper surface portion thereof. As will be described later, the mounting portion 24 of the inner container 12 is inserted into the opening 21 when the inner container 12 is mounted on the outer container 11.

  In addition, three rotation prevention grooves 20 are formed on the inner side of the lid portion 14 at equal intervals of 120 °. The anti-rotation groove 20 is formed to extend long in the mounting / removal direction (Z1, Z2 direction) of the inner container 12. The lid portion 14 having the above-described configuration is fixed to the upper end portion of the tubular portion 16 after the attachment / detachment mechanism 13 </ b> A is attached to the upper portion of the tubular portion 16.

  The attachment / detachment mechanism 13 </ b> A has a function of attaching / detaching the inner container 12 to / from the outer container 11. Specifically, the mounting / removal mechanism 13A holds the inner container 12 in the outer container 11 when the inner container 12 is mounted in the outer container 11, and the contents when the inner container 12 is operated in the detaching direction. The container 12 is allowed to be detached from the outer container 11.

  The attachment / detachment mechanism 13A includes a moving body 30A, a hook claw 32, a pressing portion 15, and the like.

  In this embodiment, the moving body 30A and the hook claw 32 are formed by integrally molding resin. However, the moving body 30 </ b> A and the hook claw 32 may be formed separately and joined together to be integrated.

  The moving body 30 </ b> A includes a moving body main body 31 and a hook claw 32. The mobile body 31 has a disk shape, and an opening 19 is formed at the center thereof. The opening 19 has a diameter that allows the mounting portion 24 of the inner container 12 to be inserted.

  The moving body 30A is configured to engage with the inner container 12 when the inner container 12 is inserted into the outer container 11 (this will be described in detail later). Therefore, after the inner container 12 is engaged with the movable body main body 31, the movable body 30A moves integrally with the inner container 12 in the mounting direction (Z1 direction).

  An anti-rotation protrusion 33 is formed on the outer peripheral side surface of the movable body 31. The rotation prevention protrusion 33 is formed with a predetermined length in the mounting / removal direction (Z1, Z2 direction). The anti-rotation protrusion 33 is formed to correspond to the anti-rotation groove 20 formed inside the lid body portion 14. Therefore, three anti-rotation protrusions 33 are also formed at equal intervals of 120 °.

  The rotation preventing projection 33 is configured to engage with the rotation preventing groove 20 and slide in the rotation preventing groove 20. Therefore, when the rotation preventing projection 33 is engaged with the rotation preventing groove 20, the moving body 30 </ b> A moves in and out of the lid 14 (outer container 11) in the rotation preventing groove 20 formation direction (Z 1, Z 2 direction). It becomes the structure which can be moved to.

  The hook claw 32 is formed so as to extend from the moving body main body 31 in the detaching direction (Z2 direction). In the present embodiment, three hook claws 32 are formed at equal intervals of 120 °.

  The hook claw 32 has a cantilever shape in which one end is integrally joined to the movable body 31 and the other end is a free end. Therefore, the hook claw 32 is configured to be elastically deformable in the directions indicated by arrows A1 and A2 in FIG. In a non-operating state (a state where no external force is applied), the hook claw 32 is displaced in the arrow A1 direction.

  The hook claw 32 has a shape extending obliquely outward as shown in FIG. 4 (see the left hook claw 32 in the figure). A step 32 a is formed inside the hook claw 32. Furthermore, the inner container 12 is configured to move inside the hook claw 32 when the inner container 12 is inserted into the outer container 11.

  The pressing part 15 is formed on the inner wall of the cylindrical part 16 so as to protrude inward (see FIG. 4). The formation position of the pressing portion 15 is configured to be located on the movement locus of the hook claw 32 that moves together with the moving body 30A. Therefore, when the hook claw 32 moves in the Z1 direction along with the movement of the moving body 30A, the pressing portion 15 engages with the hook claw 32 and presses and urges it toward the inner container 12.

  Since the hook claw 32 has a cantilever shape as described above, the hook claw 32 is elastically deformed and pressed against the inner container 12 by being pressed and urged by the pressing portion 15. The attachment / detachment mechanism 13 </ b> A holds the inner container 12 in the outer container 11 by the pressing force of the hook claws 32.

  Next, the inner container 12 will be described.

  The outer container 11 described above is a so-called exterior container, and continues to be used after all the contents are discharged. On the other hand, the inner container 12 is a refill container, and is replaced with a new one after the contents are discharged. The inner container 12 has an inner container body 12 a and a mounting portion 24.

  The inner container body 12a has a thin tube shape and is filled with contents (cosmetics in the present embodiment). The thickness (t) of the inner container body 12a is, for example, 0.05 mm ≦ t ≦ 0.3 mm.

  The mounting portion 24 is integrally formed on the upper portion of the inner container body 12a, and includes a cylindrical portion 25, a screw portion 26, a flange portion 27, a rotation restricting claw 28, and the like.

  The cylindrical portion 25 is configured to be thicker than the inner container body 12a, and thus has a high rigidity with respect to the inner container body 12a. Specifically, the thickness (w) of the cylindrical portion 25 of the mounting portion 24 is, for example, 0.5 mm ≦ w ≦ 4.0 mm.

  An opening 29 is formed at the tip of the cylindrical portion 25. The contents filled in the inner container body 12a are taken out from the opening 29. The screw portion 26 is formed on the outer periphery of the cylindrical portion 25, and the lid body 22 that seals the opening 29 is screwed thereto.

  The collar portion 27 has an annular shape and is configured to extend outward at the lower portion of the mounting portion 24. The outer diameter of the flange portion 27 is configured to be able to pass through the inside of the hook claw 32 described above and engage with the hook claw 32 when the hook claw 32 is pressed and biased inward (about this) Will be described in detail later).

  A plurality of rotation restricting claws 28 are formed on the upper portion of the collar portion 27. In the present embodiment, the rotation restricting claws 28 are plate-like protruding pieces, and four pieces are provided at intervals of 90 °.

  The rotation restricting claw 28 is configured to engage with the moving body main body 31 (moving body 30A) as the inner container 12 moves in the mounting direction (Z1 direction). Therefore, when the rotation restricting claw 28 is engaged with the movable body main body 31 as the inner container 12 is moved in the mounting direction, the inner container 12 and the movable body 30A are integrally moved in the mounting direction.

  Subsequently, in the double container 10A configured as described above, an operation when the inner container 12 is attached to the outer container 11 and an operation when the inner container 12 is detached from the outer container 11 will be described.

  In a state before the inner container 12 is attached to the outer container 11 (pre-attachment state), the moving body 30A constituting the attachment / detachment mechanism 13 is moved in the Z2 direction by its own weight. Further, the hook claw 32 formed on the moving body 30A is located at a non-operation position (position displaced in the A1 direction). Therefore, the hook claw 32 is in a state of being separated from the pressing portion 15.

  In order to mount the inner container 12 on the outer container 11 in this state before mounting, the inner container 12 is inserted into the cylindrical portion 16 of the outer container 11 from the bottom opening 17. That is, in the present embodiment, the inner container 12 is inserted from the bottom of the outer container 11. At the time of this insertion, the lid body 22 is screwed onto the screw portion 26 of the inner container 12.

  The diameter of the mounting portion 24 in the state where the lid 22 is mounted is set smaller than the diameter of the opening 19 formed in the moving body main body 31 of the moving body 30A. Therefore, by inserting the inner container 12 into the outer container 11, the mounting portion 24 of the inner container 12 enters the opening 19. FIGS. 1A, 2A, and 4 show a state in which the mounting portion 24 has entered the opening 19 (hereinafter, this state is referred to as a first mounting intermediate state).

  In this first mounting state, the moving body 30A is moving in the Z2 direction as in the state before mounting, and the hook claw 32 is located at a non-operating position (position displaced in the A1 direction) separated from the pressing portion 15. ing. Further, the rotation restricting claw 28 formed in the inner container 12 is in a state of being separated from the moving body main body 31.

  When the inner container 12 is further inserted into the outer container 11 from the first mounting state, the tip of the rotation restricting claw 28 formed on the inner container 12 comes into contact with the back surface of the movable body 31 (hereinafter, this state is referred to as the first state). 2 is in the middle of wearing). In the second mounting state, the flange portion 27 formed on the inner container 12 is in a state of facing the step portion 32 a formed on the inner side of the hook claw 32.

  In the second mounting state, the moving body 30A still moves in the Z2 direction, and the hook claw 32 is located at the non-operating position away from the pressing portion 15 as in the state before mounting. FIG. 1B, FIG. 2B, and FIG. 5 show this second mounting state.

  When the inner container 12 is further inserted into the outer container 11 from the second mounting state, the rotation restricting claw 28 is in contact with the moving body main body 31, so that the moving body 30A is integrated with the inner container 12 in the Z1 direction. Move. At this time, the collar part 27 maintains a state of facing the step part 32 a of the hook claw 32.

  Further, as the moving body 30 </ b> A moves in the Z <b> 1 direction, the hook claw 32 approaches the pressing portion 15. When the pressing portion 15 engages with the hook claw 32, the hook claw 32 is pressed and urged by the pressing portion 15 toward the flange portion 27 of the inner container 12 facing (in the direction of arrow A2 in the figure). ) Perform elastic deformation.

  As described above, the step 32 a is formed inside the hook claw 32. Therefore, when the hook claw 32 moves toward the collar part 27, the hook claw 32 comes into pressure contact with the collar part 27, and the step part 32a is engaged with the collar part 27 (hereinafter, this state is attached). Called state). FIG. 1C, FIG. 2C, and FIG. 6 show this mounted state.

  In the mounted state, since the hook claw 32 is in pressure contact with the collar portion 27, the rotation of the inner container 12 with respect to the outer container 11 is restricted. Further, the step 32a of the hook claw 32 is engaged with the flange 27, so that the inner container 12 is prevented from being detached from the outer container 11 (disengagement in the Z2 direction). Therefore, according to the double container 10A according to the present embodiment, the inner container 12 can be reliably held on the outer container 11 by the mounting / demounting mechanism 13A in the mounted state.

  On the other hand, in the mounted state, the screw portion 26 of the mounting portion 24 and the lid body 22 screwed to the mounting portion 24 are in a state of completely protruding from the upper portion of the outer container 11 (lid body portion 14). As described above, the rotation of the inner container 12 relative to the outer container 11 is restricted by the mounting / removal mechanism 13A. For this reason, the process which removes the cover body 22 from the screw part 26 can be performed easily. Also, when a dispenser or the like is mounted after the lid 22 is removed, the mounting process can be easily performed.

  Next, an operation for replacing the used inner container 12 with a new inner container 12 after all the contents have been used will be described.

  In order to replace the inner container 12, a process of strongly pulling the inner container 12 downward (Z2 direction) with respect to the outer container 11 is performed. Specifically, a process of strongly pressing the mounting portion 24 protruding upward from the lid portion 14 of the outer container 11 downward (Z2 direction) is performed.

  The inner container 12 starts to move in the detaching direction (Z2 direction) by the pressing force toward the detaching direction. Since the collar portion 27 is engaged with the stepped portion 32a in the mounted state as described above, the moving body 30A also starts moving in the detaching direction via the hook claws 32 when the inner container 12 moves in the detaching direction. To do.

  Further, when the moving body 30 </ b> A moves in the separating direction, the hook claw 32 also moves in a direction away from the pressing portion 15. Thereby, the pressing force of the hook claw 32 by the pressing portion 15 is also released, and the hook claw 32 moves in the direction of the arrow A1 by being elastically restored along with this. Then, when the hook claw 32 is separated from the inner container 12, the holding of the inner container 12 by the attachment / detachment mechanism 13 </ b> A is released, and the inner container 12 can be taken out from the outer container 11.

  As described above, the double container 10A according to the present embodiment can hold the inner container 12 on the outer container 11 by the loading / unloading mechanism 13 simply by inserting the inner container 12 into the outer container 11, and the contents are simply The inner container 12 can be taken out from the outer container 11 by pulling out (pushing out) the container 12 from the outer container 11. Therefore, according to the double container 10 </ b> A according to the present embodiment, the inner container 12 can be easily attached to and detached from the outer container 11.

  Next, the double containers 10B and 10C according to the second and third embodiments of the present invention will be described. 7 to 10 are views for explaining a double container 10B according to the second embodiment of the present invention, and FIGS. 11 to 14 illustrate a double container 10C according to the third embodiment of the present invention. FIG. 7 to 14, the same reference numerals are given to the components corresponding to those shown in FIGS. 1 to 6, and the description thereof will be omitted as appropriate.

  First, the double container 10B which is 2nd Embodiment of this invention is demonstrated using FIG. 7 thru | or FIG.

  The double container 10 </ b> A according to the first embodiment is configured to press the hook claw 32 of the mounting / removal mechanism 13 </ b> A against the collar portion 27 of the inner container 12, thereby preventing the inner container 12 from rotating with respect to the outer container 11. It was.

  In this configuration, the rotation of the inner container 12 is restricted by the frictional force between the hook claw 32 and the collar portion 27. Therefore, for example, when the tightening force between the lid body 22 and the screw portion 26 is strong, or when the user momentarily applies a large force when removing the lid body 22, the inner container 12 is attached to the outer container 11. There is a risk that it will rotate.

  Even in such a case, the double container 10B according to the present embodiment is configured so that the rotation of the inner container 12 relative to the outer container 11 can be reliably regulated. For this reason, in addition to the components of the double container 10A according to the first embodiment, the double container 10B according to the present embodiment has a rotation restricting rib 35 (the second rotation prevention according to the claims). (Corresponding to a claw).

  The rotation regulating rib 35 is provided on the back side of the movable body main body 31 (the surface facing the inserted inner container 12). The rotation restricting rib 35 has a rectangular tongue shape and is formed so as to protrude in the Z2 direction from the back surface of the movable body 31.

  The rotation restricting ribs 35 are formed integrally with the movable body 31 and are formed at six equal intervals of 60 °. The rotation restricting ribs 35 are not necessarily integrated with the movable body main body 31, and the number of the rotation restricting ribs 35 is not limited to six.

  Subsequently, an operation when the inner container 12 is mounted on the outer container 11 in the double container 10B according to the second embodiment will be described. Since the basic operation is the same as the operation of the double container 10A according to the first embodiment, only the specific operation of this embodiment will be described in the following description.

  FIG. 8 shows the first mounting state. In this first mounting state, the rotation restricting rib 35 is separated from the rotation restricting claw 28 (corresponding to the first rotation preventing claw described in the claims).

  When the inner container 12 is inserted into the outer container 11 from the first mounting state, the tip of the rotation restricting claw 28 formed on the inner container 12 comes into contact with the back surface of the movable body 31 and enters the second mounting state. . FIG. 9 shows the double container 10B in the second mounting state.

  In the second mounting state, the rotation restricting claw 28 formed on the inner container 12 enters a state between the rotation restricting ribs 35 formed on the movable body main body 31. Therefore, when the inner container 12 is rotated in the second mounting state, the rotation restricting claw 28 formed on the inner container 12 engages with the rotation restricting rib 35, thereby restricting the rotation of the inner container 12 with respect to the outer container 11. Is done.

  Since the four rotation restricting claws 28 are formed at intervals of 90 ° and the six rotation restricting ribs 35 are formed at intervals of 60 °, the rotation restricting claws 28 and the rotation restricting ribs 35 are in the second mounting state. It is also conceivable that and are spaced apart in the circumferential direction. However, in the description of the present embodiment, even if the rotation restricting claw 28 and the rotation restricting rib 35 are separated from each other in the circumferential direction, this state is possible as long as the inner container 12 can be engaged with each other if the inner container 12 is rotated. It is assumed that the rotation restricting claw 28 and the rotation restricting rib 35 are engaged.

  When the inner container 12 is further inserted into the outer container 11 from the second mounting state, the movable body 30B is integrated with the inner container 12 while maintaining the state where the rotation restricting claw 28 and the movable body main body 31 are engaged. Move in the Z1 direction. 10, the hook claw 32 is elastically deformed and pressed against the collar portion 27 by being pressed by the pressing portion 15, thereby restricting the rotation of the inner container 12.

  In the double container 10B according to the present embodiment, the rotation of the inner container 12 relative to the outer container 11 in the mounted state is regulated by the hook claw 32 being crimped to the collar portion 27, and the rotation regulating claw 28 is a rotation regulating rib. It is also regulated by engaging with 35. Therefore, even if a strong rotational force is applied to the inner container 12 in the mounted state, the rotation of the inner container 12 with respect to the outer container 11 is reliably restricted, and the reliability of the double container 10B can be improved.

  Next, a double container 10C according to a third embodiment of the present invention will be described with reference to FIGS.

  In the double container 10 </ b> A according to the first embodiment, the step 32 a formed on the hook claw 32 of the mounting / removal mechanism 13 </ b> A engages with the flange portion 27 of the inner container 12, whereby the inner container 12 is moved relative to the outer container 11. It was set as the structure by which drop prevention was aimed at. However, when a large force is applied to the inner container 12 in the detaching direction, the collar portion 27 may be detached from the stepped portion 32 a and the inner container 12 may be detached from the outer container 11.

  Even in such a case, the double container 10C according to the present embodiment is configured to reliably prevent the inner container 12 from being detached from the outer container 11. For this reason, the double container 10C according to the present embodiment includes, in addition to the components of the double container 10A according to the first embodiment, a lock piece 37 and an engaging recess 16c (an engagement portion described in claims). (Corresponding to the joint portion) is added.

  The lock piece 37 is formed integrally with the movable body main body 31, and is formed to extend from the back surface of the movable body main body 31 in the separation direction (Z2 direction). A lock claw 37a is formed at the tip of the lock piece 37 so as to protrude outward (toward the inner wall of the outer container body 11a). The lock piece 37 is a cantilever arm and is configured to be elastically deformable outward.

  In the present embodiment, three hook claws 32 are formed on the back surface of the mobile body 31 at equal intervals of 120 °. The hook claws 32 are also formed on the back surface of the movable body 31, but the lock pieces 37 are formed so as to be positioned between the hook claws 32. Therefore, the hook claw 32 and the lock piece 37 do not interfere with each other.

  The engaging recess 16c is formed on the inner side (inner wall) of the outer container body 11a. The formation position of the engagement recess 16c is set to a position facing the lock claw 37a when the lock piece 37 (moving body 30C) is moved to the mounting position in accordance with the insertion of the inner container 12.

  Furthermore, in this embodiment, the formation position of the engagement recessed part 16c is formed in the position where the cover part 14 and the cylindrical part 16 are joined. By forming the engagement recess 16c at this position, the mold structure of the outer container 11 can be simplified even on the inner wall of the outer container body 11a, and the engagement recess 16c can be easily formed.

  An engaging portion 16b is formed at a lower position of the engaging recess 16c. The engaging portion 16 b is a protrusion formed so as to protrude inward with respect to the inner surface of the tubular portion 16. The height of the engaging recess 16c is set to a height at which the lock claw 37a can get over when the lock piece 37 moves toward the mounting position, as will be described later.

  Subsequently, an operation when the inner container 12 is mounted on the outer container 11 in the double container 10C according to the third embodiment will be described. In the third embodiment, since the basic operation is the same as that of the double container 10A according to the first embodiment, only the specific operation of the present embodiment will be described in the following description. To do.

  FIG. 12 shows the first mounting state. In the first mounting state, the lock piece 37 is separated from the engagement recess 16c.

  When the inner container 12 is inserted into the outer container 11 from the middle of the first mounting state, the tip of the rotation restricting claw 28 formed on the inner container 12 as described above comes into contact with the back surface of the movable body main body 31 and is second mounted. It becomes a halfway state. FIG. 13 shows the double container 10C in the second mounting state. In the second mounting state, the lock piece 37 is still separated from the engaging recess 16c.
