Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in this type of container, designs such as characters and patterns may be given as decorations to the outer container or a lid attached to the container. For example, when the relative positions of the outer container and the lid are determined, the design given to the outer container and the design given to the lid may create a unified aesthetic appearance.

[0006] In such cases, the relative positions of the outer container and the lid may become indeterminate due to the inability to determine the relative positions of the inner and outer containers. This raises concerns that the design applied to the container may not be able to achieve its intended aesthetic effect.

[0007] Furthermore, in cases where the outer container is formed to be transparent or semi-transparent, it is conceivable that designs may be applied to both the outer and inner containers, and that the designs of the outer and inner containers may work together to create a unified aesthetic.

[0008] In such cases, as described above, if the relative positions of the inner and outer containers are not fixed, there is a concern that the design applied to the container will also be unable to achieve its intended aesthetic effect.

[0009] This invention has been made in view of the above circumstances, and aims to provide a container that can appropriately position the inner container and the outer container. [Means for solving the problem]

[0010] A container for achieving the above objective comprises a cylindrical inner container filled with contents and an outer container to which the inner container is detachably attached, and has a locking portion disposed at any circumferential part of the inner container and a locking portion disposed at any circumferential part of the opening edge of the outer container to which the inner container is joined, with which the locking portion engages.

[0011] According to this, the locking portion of the inner container engages with the locking portion of the outer container, thereby enabling proper positioning of the inner and outer containers.

[0012] The locking portion of this container is formed by having a projection that protrudes downward toward the inner container and a hook that bends outward from the projection, and the locking portion is formed by a notch that is cut out toward the outside of the outer container from an open edge made by the tip of a flange that bends inward toward the outer container.

[0013] The locking portion of this container has a first locking portion disposed at any part in the circumferential direction of the inner container and a second locking portion disposed opposite the first locking portion in the radial direction of the inner container, and the locked portion has a first locked portion which is formed by cutting outwards from the open edge made by the tip of a flange that bends inwards from the outer container and is locked by the first locking portion, and a second locked portion which is formed by cutting outwards from the open edge made by the tip of a flange that bends inwards from the outer container and is locked by the second locking portion.

[0014] The locking portion of this container has a first locking portion disposed at any part in the circumferential direction of the inner container and a second locking portion disposed opposite the first locking portion in the radial direction of the inner container. The locked portion has a first locked portion which is formed by cutting outwards from an open edge made by the tip of a flange that bends inwards from the outer container and engages with the first locking portion, and a second locked portion which is formed by cutting outwards from an open edge made by the tip of a flange that bends inwards from the outer container and engages with the second locking portion. An indicator is formed on the first locking portion and the first locked portion to indicate that the first locking portion and the first locked portion are locked together.

[0015] Furthermore, this container has a guide disposed at any circumferential portion of the inner container and protruding downward toward the inner container, and a guide receiver formed to fit with the guide and disposed at any circumferential portion of the open edge of the outer container.

[0016] This container has: a first locking portion formed by cutting outwards from an open edge made by the tip of a flange that bends inwards from the outer container; a first guide receiver formed by cutting outwards from the open edge of the outer container, spaced circumferentially apart from the first locking portion; a second locking portion formed by cutting outwards from an open edge of the outer container, spaced circumferentially apart from the first guide receiver, and facing the first locking portion in the radial direction of the outer container; and a second guide receiver formed by cutting outwards from an open edge of the outer container, spaced circumferentially apart from the second locking portion, and facing the first guide receiver in the radial direction of the outer container.

[0017] This container has a first locking portion formed by cutting outwards from an open edge made by the tip of a flange that bends inwards from the outer container; a first guide receiver formed by cutting outwards from the open edge of the outer container, spaced circumferentially apart from the first locking portion; a second locking portion formed by cutting outwards from an open edge of the outer container, spaced circumferentially apart from the first guide receiver, and facing the first locking portion in the radial direction; and a second guide receiver formed by cutting outwards from an open edge of the outer container, spaced circumferentially apart from the second locking portion, and facing the first guide receiver in the radial direction. The notch width of the first guide in the circumferential direction at the open edge of the outer container and the notch width of the second guide in the circumferential direction at the open edge of the outer container are formed to be different from each other. [Effects of the Invention]

[0018] According to this invention, the positioning of the inner container and the outer container can be appropriately performed. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0020] Next, based on FIGS. 1 to 10, a container according to an embodiment of the present invention will be described.

[0021] FIG. 1 is a perspective view for explaining the outline of a container according to the present embodiment. As shown in the figure, the container 10 has a double structure including an inner container 20, an outer container 30 to which the inner container 20 is detachably attached, and a lid 40 in the present embodiment. It is assumed that a material such as a hair styling product like gel or wax is filled in the inner container 20 as the content.

[0022] In this embodiment, this container 10 may be configured as a refillable container that can be replaced with a new inner container 20 filled with the content after all the content filled in the inner container 20 has been used up.

[0023] Figure 2 is a schematic diagram illustrating the configuration of the inner container 20, Figure 3 is a cross-sectional view taken along line III-III in Figure 2, Figure 4 is a schematic diagram illustrating the configuration of the inner container 20, and Figure 5 is a cross-sectional view taken along line VV in Figure 4.

[0024] Figure 4 shows the inner container 20 from Figure 2, with a rotation of 45° in the rotational direction R, using axis A as the axis of rotation.

[0025] As shown in the figure, the inner container 20 is a hollow cylindrical shape in which the body portion 21, band portion 22, and neck portion 23 are continuously and integrally formed, and the contents are filled into the hollow interior through the neck portion 23 which opens upward.

[0026] In this embodiment, the body portion 21 forms the bottom of the inner container 20, and a band portion 22 is formed continuously with the body portion 21, protruding outward from the body portion 21 and folded back toward the lower side of the body portion 21 to partially cover the body portion 21, that is, it is formed with an expanded diameter relative to the body portion 21 and extends in a band shape in the circumferential direction of the body portion 21.

[0027] In this embodiment, the band portion 22 has a first locking portion 22A, a second locking portion 22B, a first guide 22C, and a second guide 22D. The first locking portion 22A and the second locking portion 22B constitute a locking portion, and the first guide 22C and the second guide 22D constitute a guide.

[0028] As shown in Figures 2 and 3, in this embodiment, the first locking portion 22A is disposed at any point in the circumferential direction of the belt portion 22, and the second locking portion 22B is disposed opposite the first locking portion 22A in the radial direction of the belt portion 22.

[0029] In this embodiment, the first locking portion 22A and the second locking portion 22B have a projection 22a that protrudes downward from the band portion 22 toward the inner container 20 and a hook 22b that bends outward from the projection 22a toward the outside of the inner container 20, and are formed in a hook shape in cross-section.

[0030] Incidentally, as shown in Figure 2, in this embodiment, a locking portion indicator ID1 is formed at the position where the first locking portion 22A is provided in the belt portion 22, so as to distinguish it from the second locking portion 22B, which is not shown in Figure 2, to indicate that it is the first locking portion 22A.

[0031] As shown in Figures 4 and 5, in this embodiment, the first guide 22C is disposed at any point in the circumferential direction of the belt portion 22, and the second guide 22D is disposed in the radial direction of the belt portion 22 opposite to the first guide 22C.

[0032] The first guide 22C and the second guide 22D are formed to protrude downward from the band portion 22 toward the inner container 20. In this embodiment, the protrusion widths of the first guide 22C and the second guide 22D toward the inner container 20 are formed to be different from those of the first guide 22C and the second guide 22D. This point will be described later.

[0033] Figure 6 is a diagram illustrating the general layout of the inner container 20 as seen from arrow D in Figure 2. As shown in the figure, in this embodiment, the inner container 20 has a first locking portion 22A located in the band portion 22 in the direction indicated by arrow N.

[0034] In this embodiment, the first guide 22C is positioned in the part of the band portion 22 that corresponds to the direction indicated by arrow W, which is spaced apart from the first locking portion 22A in the circumferential direction of the band portion 22 indicated by arrow C.

[0035] In this embodiment, the angle θ1 formed by the center position of the first locking portion 22A from the axis A of the inner container 20 and the center position of the first guide 22C from the axis A of the inner container 20 is set to 45°.

[0036] In this embodiment, the second locking portion 22B is provided in a portion of the band portion 22 that is spaced apart from the first guide 22C in the circumferential direction C, corresponding to the direction indicated by the arrow S, and is located in the radial direction of the band portion 22 that faces the first locking portion 22A.

[0037] In this embodiment, the angle θ2 formed by the center position of the first guide 22C from the axis A of the inner container 20 and the center position of the second locking portion 22B from the axis A of the inner container 20 is set to 45°.

[0038] Furthermore, in this embodiment, the second guide 22D is provided in a portion of the band portion 22 that is spaced apart from the second locking portion 22B in the circumferential direction C, corresponding to the direction indicated by the arrow E, and which faces the first guide 22C in the radial direction of the band portion 22.

[0039] In this embodiment, the angle θ3 formed by the center position of the second locking portion 22B from the axis A of the inner container 20 and the center position of the second guide 22D from the axis A of the inner container 20 is set to 45°, and the angle θ4 formed by the center position of the second guide 22D from the axis A of the inner container 20 and the center position of the first locking portion 22A from the axis A of the inner container 20 is set to 45°.

[0040] As described above, the first guide 22C and the second guide 22D are formed with different protruding widths that project downward toward the inner container 20, i.e., the guide width of the first guide 22C and the guide width of the second guide 22D. In this embodiment, the guide width L2 of the second guide 22D is wider than the guide width L1 of the first guide 22C.

[0041] As shown in Figures 2 and 4, in this embodiment, the neck portion 23 is reduced in diameter relative to the band portion 22 and is formed continuously with the band portion 22, opening to the upper side of the inner container 20. A threaded portion 23a is formed in this neck portion 23 for attaching the lid 40, which will be described later, to the inner container 20.

[0042] Figure 7 is a cross-sectional view illustrating the outline of the outer container 30. As shown in the figure, in this embodiment, the outer container 30 is cylindrical with a translucent circumferential surface 31 and an open bottom, and an open edge 33 is formed so that the top surface is partially open.

[0043] Figure 8 is a diagram illustrating the outline of the outer container 30 as seen from the arrow U in Figure 7. As shown in the figure, in this embodiment, the outer container 30 is provided with a flange 32 that is formed by bending from the circumferential surface 31 side of the outer container 30 toward the inside of the outer container 30, and the tip 32a of this flange 32 forms an open end edge 33.

[0044] In this embodiment, a first locking portion 33A, a second locking portion 33B, a first guide receiver 33C, and a second guide receiver 33D are formed on the open edge 33. The first locking portion 33A and the second locking portion 33B constitute a locking portion, and the first guide receiver 33C and the second guide receiver 33D constitute a guide receiver.

[0045] In this embodiment, the first locking portion 33A is positioned at any circumferential portion of the open edge 33, that is, at a portion corresponding to the direction indicated by the arrow S on the open edge 33, and is formed by cutting out from the open edge 33 toward the outside (circumferential surface 31 side) of the outer container 30.

[0046] In this embodiment, a locking portion indicator ID2 is formed on the flange 32 at the position where the first locking portion 33A is located on the open edge 33, to distinguish it from the second locking portion 33B, and to indicate that it is the first locking portion 33A.

[0047] In this embodiment, a second guide receiver 33D is provided at a portion of the opening edge 33 corresponding to the direction indicated by arrow E, which is spaced circumferentially away from the first locking portion 33A by arrow C, and is formed by cutting out from the opening edge 33 toward the outside (circumferential surface 31 side) of the outer container 30.

[0048] In this embodiment, the angle θ1 formed by the center position of the first locking portion 33A from the axis A of the outer container 30 and the center position of the second guide receiver 33D from the axis A of the outer container 20 is set to 45°.

[0049] In this embodiment, the second locking portion 33B is provided in a portion of the opening edge 33 that is spaced circumferentially from the second guide receiver 33D, in the direction indicated by arrow C, and in a portion of the opening edge 33 that is opposite the first locking portion 33A in the radial direction of the opening edge 33, and is formed by cutting out from the opening edge 33 toward the outside (circumferential surface 31 side) of the outer container 30.

[0050] In this embodiment, the angle θ2 formed by the center position of the second guide receiver 33D from the axis A of the outer container 30 and the center position of the second locking portion 33B from the axis A of the outer container 20 is set to 45°.

[0051] In this embodiment, the first guide receiver 33C is positioned at a location on the opening edge 33 corresponding to the direction indicated by arrow W, spaced circumferentially from the second locking portion 33B by arrow C, and is formed by cutting out a section from the opening edge 33 toward the outside (circumferential surface 31 side) of the outer container 30.

[0052] In this embodiment, the angle θ3 formed by the center position of the second locking portion 33B from the axis A of the outer container 30 and the center position of the first guide receiver 33C from the axis A of the outer container 20 is set to 45°, and the angle θ4 formed by the center position of the first guide receiver 33C from the axis A of the outer container 30 and the center position of the first locking portion 33A from the axis A of the outer container 30 is set to 45°.

[0053] The first guide receiver 33C and the second guide receiver 33D are formed with different notch widths. In this embodiment, the notch width L2 of the second guide receiver 33D is wider than the notch width L1 of the first guide receiver 33C.

[0054] In other words, when the inner container 20 is mounted on the outer container 30, the first guide 22C of the inner container 20 is fitted into the first guide receiver 33C of the outer container 30, and the second guide 22D of the inner container 20 is fitted into the second guide receiver 33D of the outer container 30.

[0055] As shown in Figure 1, in this embodiment, the lid 40 is cylindrical with an upper surface 41 and a circumferential surface 42, and an open lower surface, and a threaded portion (not shown) corresponding to the threaded portion 23a formed on the neck portion 23 of the inner container 20 is formed on the inner circumferential surface.

[0056] Next, we will explain the procedure for assembling the container 10 or the procedure for attaching the new inner container 20 to the outer container 30.

[0057] Figure 9 is an exploded view illustrating the general structure of the container 10. As shown in the figure, when attaching the inner container 20 to the outer container 30, the first locking portion 22A of the inner container 20 is positioned on the first locking portion 33A of the outer container 30, using the locking portion indicator ID1, which indicates the first locking portion 22A, and the locking portion indicator ID2, which indicates the first locking portion 33A, as guides.

[0058] In this state, when the inner container 20 is pushed into the outer container 30, the hook 22b of the first locking part 22A locks into the first locked part 33A, and the hook 22b of the second locking part 22B locks into the second locked part 33B, so that the inner container 20 is attached to the outer container 30 at the location of the first locking part 22A.

[0059] Therefore, since the inner container 20 and the outer container 30 can be positioned appropriately, for example, as shown in Figure 10, the design applied to the circumferential surface 31 of the outer container 30 and the design applied to the upper surface 41 of the lid 40 attached to the inner container 20 are positioned in the circumferential direction C of the container 10, and it can be expected that a unified aesthetic appearance will be created by the design applied to the outer container 30 and the design applied to the lid 40.

[0060] Furthermore, if the outer container 30 is formed in a semi-transparent or transparent manner, and designs are applied to both the outer container 30 and the inner container 20, and the outer container 30 and the inner container 20 are positioned in the circumferential direction of the container 10, the design applied to the inner container 20 will be semi-transparent or transparent to the outer container 30, and it is expected that a unified aesthetic appearance will be created by the designs applied to the outer container 30 and the inner container 20.

[0061] On the other hand, in the manufacturing process of the container 10, whether the design is applied to the inner container 20 and the lid 40, or to the inner container 20 and the outer container 30, the positioning of the inner container 20 and the outer container 30 is appropriately performed, so that the design can be accurately applied so that a unified aesthetic appearance is created by the design of the inner container 20 and the design of the lid 40, or so by the design of the inner container 20 and the design of the outer container 30.

[0062] Incidentally, when the first locking portion 22A is locked to the first locked portion 33A and the second locking portion 22B is locked to the second locked portion 33B, as shown in Figure 9, the first guide 22C of the inner container 20 fits into the first guide receiver 33C of the outer container 30, and the second guide 22D of the inner container 20 fits into the second guide receiver 33D of the outer container 30.

[0063] In this way, the inner container 20 is mounted on the outer container 30, the first guide 22C is fitted into the first guide receiver 33C, and the second guide 22D is fitted into the second guide receiver 33D, thereby restricting the relative rotation of the inner container 20 and the outer container 30.

[0064] On the other hand, when attempting to lock the first locking portion 22A and the second locked portion 33B (the second locking portion 22B and the first locked portion 33A), the notch width of the first guide receiver 33C and the guide width of the second guide 22D are different, and the notch width of the second guide receiver 33D and the guide width of the second guide 22D are also different. As a result, they do not fit together, and the inner container 20 is prevented from being attached to the outer container 30.

[0065] With the inner container 20 attached to the outer container 30, the lid 40 is attached to the threaded portion 23a of the neck portion 23 of the inner container 20, thereby assembling the container 10 as shown in Figure 10.

[0066] The present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.

[0067] In the above embodiment, the case where the guide width L2 of the second guide 22D is wider than the guide width L1 of the first guide 22C was described. However, for example, the guide width of the first guide 22C may be wider than the guide width of the second guide 22D.

[0068] In this case, the notch width of the first guide receiver 33C will be wider than the notch width of the second guide receiver 33D.

[0069] The locking portion indicator ID1 and the locked portion indicator ID2 described in the above embodiment are not limited to the patterns (designs) or shapes shown in each figure, but may be any pattern or shape that can indicate that the first locking portion 22A and the second locked portion 33A are locked together.
