Description

  The present invention relates to a container for holding a liquid, and more particularly to a container having a multiple structure.

  In the field of cosmetic liquids such as lotion and cosmetic liquids, not only the quality of products but also the brand power of a company is important. As part of improving its brand power, companies are striving to make cosmetic liquid containers more beautiful. For example, he asks a famous designer to design a container. Some users are attracted by the beautiful containers they make and decide to purchase. Some such users like the container as much as they feel as part of it.

  However, once the cosmetic liquid is used up, the container is basically only discarded. This would be harsh for users who liked the container. There is also concern about the environmental impact. Therefore, it will be a question of whether or not the container can be reused, but such a reuse is difficult for containers for cosmetic liquids. This is because cosmetic liquids generally require higher cleanliness than detergents and shampoos. Although an operation of transferring the cosmetic liquid to the container occurs in the process of reuse, there is a possibility that foreign matters and germs may be mixed in the cosmetic liquid during the operation.

  Therefore, conventionally, for example, Patent Document 1 proposes a double container including an inner container and an outer container that function as a refill container.

  FIG. 1 is an exploded perspective view showing a configuration of a double container 10 according to an embodiment. The double container 10 includes an inner container 12, an outer container 14, a holder 16, a cap 18, and a lower lid 20.

  The outer container 14 is a substantially transparent material, for example, a glass container. The outer container 14 includes a cylindrical outer body portion 14a extending along the axial direction A1 and a neck portion 14b formed on one end side of the outer body portion 14a. The other end side of the outer body portion 14a is open. An outer container opening 14c is formed in the neck portion 14b. Hereinafter, one end side of the outer body portion 14a will be described as an upper side, and the other end side will be described as a lower side.

  The inner container 12 is a softer material than the material of the outer container 14, for example, a resin container such as PET (Polyethylene terephthalate). The inner container 12 holds a cosmetic liquid such as a skin lotion. The inner container 12 is accommodated in the outer container 14. The inner container 12 includes a cylindrical inner body portion 12a having a smaller diameter than the outer body portion 14a, a mouth portion 12b formed on the upper end side of the inner body portion 12a, and a knob formed on the lower end side of the inner body portion 12a. 12c.

  When the cosmetic liquid held in the inner container 12 is taken out, the cosmetic liquid passes through the mouth portion 12b and goes out. In a state where the inner container 12 is accommodated in the outer container 14, the mouth portion 12 b is inserted into the outer container opening 14 c and penetrates the outer container opening 14 c and is exposed to the outside of the outer container 14.

  The knob 12c is configured to hold the cosmetic liquid inside. That is, in the present embodiment, the knob 12c is not formed as a PET lump, but the inside of the knob 12c communicates with the inside of the inner body portion 12a. In this case, the knob 12c is provided in the inner container 12, and the amount of the cosmetic liquid that can be held by the inner container 12 can be increased using the capacity of the knob 12c.

  FIG. 2 is a bottom view of the double container 10 with the lower lid 20 removed. The knob 12c is configured to prevent the inner container 12 from becoming independent. The knob 12c protrudes from the lower surface 12f of the body portion 12a and extends along a radial direction orthogonal to the axial direction A1. In particular, the knob 12c is formed by the lower surface 12f of the body portion 12a projecting from both opposite sides in the radial direction toward the central portion, and the projecting portion extends in the radial direction perpendicular to the projecting direction of the lower surface 12f.

  Returning to FIG. 1, the lower surface 12 g of the knob 12 c is a downwardly convex curved surface. When the inner container 12 is attached to the outer container 14, the space 30 formed by the knob 12c, the lower surface 12f of the inner body part 12a, and the outer body part 14a of the outer container 14 is such that a human fingertip can easily enter. Have a size.

  The holder 16 is a material softer than the material of the outer container 14, for example, a ring-shaped member made of PET. The holder 16 is attached to the outer container opening 14c of the neck portion 14b. When the mouth 12b of the inner container 12 is inserted into the outer container opening 14c, the holder 16 is interposed between the mouth 12b and the outer container opening 14c. That is, the outer peripheral surface 16a of the holder 16 is in contact with the outer container opening 14c, and the inner peripheral surface 16b of the holder 16 is in contact with the mouth portion 12b.

  The cap 18 includes a lid body portion 18a, a packing 18b, and an inner plug 18c. The cap 18 is screwed into the mouth portion 12b. In particular, a male screw 12e is formed on the outer peripheral surface 12d of the mouth portion 12b, and a corresponding female screw 18d is formed on the lid body portion 18a of the cap 18. The cap 18 has a diameter larger than the diameter of the inner peripheral surface 16 b of the holder 16 so as not to pass through the holder 16. In this case, it is possible to prevent the inner container 12 from being unintentionally detached from the outer container 14 with the cap 18 attached to the inner container 12.

  The lower lid 20 is a lid made of a material softer than the material of the outer container 14, for example, PET. The lower lid 20 is configured to be detachable from the lower end of the outer body portion 14a. In particular, the lower lid 20 is attached to the lower end of the outer body portion 14a by its own elasticity and frictional resistance with the surface of the outer body portion 14a. The lower lid may be configured to be screwed to the lower end of the outer body portion 14a.

  FIG. 3 is a perspective view of the mouth portion 12 b of the inner container 12. A first protrusion 22 and a second protrusion 24 (not shown in FIG. 3) larger than the first protrusion 22 are formed on the outer peripheral surface 12d of the mouth portion 12b. The 1st protrusion 22 and the 2nd protrusion 24 are formed in the outer peripheral surface 12d of the opening part 12b below the external thread 12e. The second protrusion 24 is located on the opposite side of the first protrusion 22.

  4A and 4B are sectional perspective views of the holder 16. FIG. 4A is a view of the cross section seen from one side, and FIG. 4B is a view seen from the other side. Concave portions 26 and 28 corresponding to the two protrusions 22 and 24 of the mouth portion 12b are formed on the inner peripheral surface 16b of the holder 16, respectively.

  The first recess 26 corresponds to the first protrusion 22, and in particular is configured so that the first protrusion 22 can pass but the second protrusion 24 cannot pass. The first recess 26 includes a first groove 26a that extends partway from the lower end of the inner peripheral surface 16b of the holder 16 and a second groove 26b that extends along the circumferential direction from the upper end of the first groove 26a. Similarly, the second recess 28 has a first groove 28a and a second groove 28b.

The circumferential width W1 of the first groove 26a of the first recess 26 corresponds to the circumferential width W2 of the first protrusion 22 (see FIG. 3). In particular, the circumferential width W 1 of the first groove 26 a is larger than the circumferential width W 2 of the first protrusion 22 and smaller than the circumferential width of the second protrusion 24. The width W4 in the axial direction A1 of the second groove 26b of the first recess 26 corresponds to the width W6 in the axial direction A1 of the first protrusion 22 (see FIG. 3). In particular, the width W4 of the second groove 26b in the axial direction A1 is larger than the width W6 of the first protrusion 22 in the axial direction A1.
The circumferential width W3 of the first groove 28a of the second recess 28 corresponds to the circumferential width of the second protrusion 24, and is particularly larger than the circumferential width of the second protrusion 24. The width W5 of the second groove 28b of the second recess 28 in the axial direction A1 corresponds to the width of the second protrusion 24 in the axial direction A1, and is particularly larger than the width of the second protrusion 24 in the axial direction A1.

A first vertical rib 40 projecting inward in the radial direction is provided at a portion of the second groove 26b of the first recess 26 on the first groove 26a side, that is, at the inlet of the second groove 26b. The height of the first vertical rib 40 is smaller than the depth of the second groove 26b. The first vertical rib 40 restricts the first protrusion 22 from returning to the first groove 26a side when the first protrusion 22 is fitted in the second groove 26b. In particular, the first vertical rib 40 makes it difficult for the first protrusion 22 to return to the first groove 26a side. Thereby, after setting the inner container 12 to the outer container 14, it can suppress that the inner container 12 slip | deviates when the cap 18 is opened or closed.
A second vertical rib 42 similar to the first vertical rib 40 is provided at the entrance of the second groove 28 b of the second recess 28.
One or more positioning marks may be provided on the upper surface or side surface of the holder 16.

The operation of the double container 10 configured as described above will be described.
The user inserts the inner container 12 in a state where the cap 18 is not attached into the inner side of the outer container 14 in a state where the holder 16 is attached to the outer container opening 14c. When the mouth 12 b of the inner container 12 enters the holder 16 to some extent, the two protrusions 22 and 24 of the mouth 12 b hit the lower end of the holder 16. In this state, the user rotates the inner container 12 around the axial direction A1 with respect to the outer container 14, the first protrusion 22 is fitted in the first groove 26a of the first recess 26, and the second protrusion 24 is the second. Find the angular position that fits into the first groove 28a of the recess 28. At this time, the user applies torque to the inner container 12 by pinching and turning the knob 12c.

  When the first protrusion 22 fits in the first recess 26 and the second protrusion 24 fits in the second recess 28, the user moves the inner container 12 further upward. Then, the first protrusion 22 moves upward in the first groove 26 a of the first recess 26, and the second protrusion 24 moves upward in the first groove 28 a of the second recess 28. The user moves the inner container 12 upward until the first protrusion 22 hits the upper end of the first groove 26 a of the first recess 26 or the second protrusion 24 hits the upper end of the first groove 28 a of the second recess 28.

  FIG. 5 is a cross-sectional view showing an engagement state between the mouth portion 12 b and the holder 16 before the inner container 12 is locked with respect to the outer container 14. In FIG. 5, the first protrusion 22 hits the upper end of the first groove 26 a of the first recess 26, and the second protrusion 24 hits the upper end of the first groove 28 a of the second recess 28. Here, when the user pinches the knob 12c and rotates the inner container 12 in the first direction (clockwise in FIG. 5) around the axial direction A1 with respect to the outer container 14, the first protrusion 22 is in the first groove. The second protrusion 24 moves from the first groove 28a to the second groove 28b. The second groove 26b of the first recess 26 restricts the movement of the first protrusion 22 along the axial direction A1, and the second groove 28b of the second recess 28 restricts the movement of the second protrusion 24 along the axial direction A1. To do. Therefore, the state of the double container 10 is that the mouth portion 12b is fixed to the outer container opening 14c from the unlocked state in which the mouth portion 12b is easily movable along the axial direction A1 with respect to the outer container opening 14c. To the locked state.

  FIG. 6 is a cross-sectional view showing an engagement state between the mouth portion 12 b and the holder 16 after the inner container 12 is locked with respect to the outer container 14. The first protrusion 22 is held in the second groove 26 b of the first recess 26, and the second protrusion 24 is held in the second groove 28 b of the second recess 28. Here, the user pinches the knob 12c and rotates the inner container 12 with respect to the outer container 14 in the second direction (counterclockwise in FIG. 6) opposite to the first direction around the axial direction A1, The first protrusion 22 moves from the second groove 26b to the first groove 26a, and the second protrusion 24 moves from the second groove 28b to the first groove 28a. Therefore, the state of the double container 10 is switched from the locked state to the unlocked state.

  FIG. 7 is a front view of the double container 10 after the inner container 12 is locked with respect to the outer container 14. A first pattern 32 such as a text-based pattern or a picture such as a logo, a brand name, or a product name is printed on the outer peripheral surface of the outer container 14, and a first pattern 32 corresponding to the first pattern 32 is printed on the outer peripheral surface of the inner container 12. Two patterns 34 are printed. The first pattern 32 and the second pattern 34 are aligned with respect to a virtual straight line parallel to the axial direction A1. When the double container 10 is unlocked, the first pattern 32 and the second pattern 34 are shifted. In this case, the user can easily determine whether or not the double container 10 is in the locked state. In addition, since the double container 10 is normally placed in a user's room or the like in a locked state, the user makes the double container 10 in a more beautiful state in which the first pattern 32 and the second pattern 34 are aligned longer. Watch time.

  According to the double container 10 according to the present embodiment, the inner container 12 is rotated with respect to the outer container 14 to switch between the locked state and the unlocked state, and further, such rotation is easier. The inner container 12 is provided with a knob 12c. Therefore, the user can switch between the locked state and the unlocked state by pinching and turning the knob 12c, so that the inner container 12 can be attached to and detached from the outer container 14 more easily and reliably. .

  Further, since the knob 12c is provided on the opposite side of the mouth portion 12b, the configuration of the engaging portion between the inner container 12 and the outer container 14 becomes relatively simple, and the number of parts can be reduced. As a result, it is possible to provide the double container 10 that is more cost-effective and excellent in durability.

  Particularly in applications where the double container 10 is used to hold cosmetic liquid and the refill is performed by replacing the inner container 12, the user transfers the liquid from container to container himself, like a conventional refill. This saves time because there is no need to do work. Further, in the present embodiment, since the degree of contact of the cosmetic liquid with the outside air during refilling can be reduced, the sanitary requirement for the cosmetic liquid can be satisfied while realizing the refilling of the cosmetic liquid. Can do.

  Further, in the double container 10 according to the present embodiment, the knob 12c prevents the inner container 12 from becoming independent. Accordingly, in the refill application, the inner container 12 filled with the cosmetic liquid is sold for refilling. However, the provision of the knob 12c may make the use of the inner container 12 more difficult. it can. As a result, the user is prompted to use the inner container 12 and the outer container 14 as a set.

  For companies that provide cosmetic liquids, not only the quality of cosmetic liquids themselves, but also the beauty of such cosmetic liquid containers is important for maintaining and enhancing brand power. Since the double container 10 is designed so that its beauty is enhanced when the inner container 12 is attached to the outer container 14, the inner container 12 alone cannot fully exhibit its beauty. Therefore, by prompting the user to use the inner container 12 and the outer container 14 as a set, the user can recognize the beauty of the double container 10. As a result, the brand power of companies that provide cosmetic liquids is enhanced.

  The configuration and operation of the double container according to the embodiment have been described above. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective components, and such modifications are also within the scope of the present invention.

  In the embodiment, the double container 10 including the inner container 12 and the outer container 14 has been described, but the present invention is not limited to this. For example, the technical idea of the present embodiment may be applied to a multiple container in which three or more containers are nested.

In the embodiment, the configuration of the lower lid 20 configured to be detachable from the lower end of the outer body portion 14a has been described. The lower lid may be configured to limit relative movement of the knob 12c when the inner container 12 is locked with respect to the outer container 14 and the lower lid is attached to the outer container 14.
FIG. 8 is a partial cross-sectional view of a lower lid 50 according to a modification. The lower lid 50 includes annular first and second projecting portions 54 and 56 forming an annular lower lid concave portion 52 into which the lower end of the outer body portion 14 a is inserted, and a first portion provided on the inner side of the lower lid concave portion 52. 3 protrusions 58. The first protrusion 54 surrounds the second protrusion 56, and the second protrusion 56 surrounds the third protrusion 58. When the inner container 12 is locked with respect to the outer container 14 and the lower lid 50 is attached to the outer container 14, the upper end of the third protrusion 58 is in contact with the lower surface 12g of the knob 12c. Thereby, the movement of the knob 12c in the radial direction is limited. As a result, the inner container 12 is less likely to move relative to the outer container 14, and a double container with a higher-class feeling and stability can be realized. Further, the wear of the joined portion of the inner container 12 due to the vibration of the inner container 12 relative to the outer container 14 can be reduced.
