[0011] [Figure 1] This is a partial longitudinal cross-sectional side view showing a refill container of one embodiment of the present invention. [Figure 2] This is a longitudinal cross-sectional view showing the state after the lid and replacement container have been removed from the state shown in Figure 1. [Figure 3] This is a longitudinal cross-sectional view showing the state after the operating part is pressed down from the state shown in Figure 2. [Modes for carrying out the invention]

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0013] As shown in FIG. 1, in one embodiment of the present invention, the refill container 1 includes a container body 4 having an outer container 2 and an inner container 3, a replacement container 5 for containing a content (not shown), a lid body 6, and a lid 8 having a packing 7. The content is not particularly limited and may be, for example, cosmetics, foods, drugs, etc.

[0014] Each of the outer container 2, the inner container 3, the replacement container 5, and the lid body 6 is an integrally molded product formed by injection molding using a resin material such as an olefin resin or a polyester resin. Note that these members are not limited to being formed by injection molding, nor are they limited to being formed of a resin material. Also, these members are not limited to being integrally molded products, and may be configured by assembling a plurality of members. The lid 8 is not limited to having the packing 7 separately from the lid body 6. The refill container 1 is not limited to having the lid 8.

[0015] The outer container 2, the inner container 3, and the replacement container 5 are combined to form a bottomed cylindrical portion 9 centered on the central axis O. The bottomed cylindrical portion 9 has a body portion 9a and a bottom portion 9b connected to the lower end portion of the body portion 9a, and the upper portion of the body portion 9a constitutes a mouth portion 9c.

[0016] For the sake of convenience of explanation, the direction along the central axis O is also referred to as the vertical direction, the direction from the side of the bottom portion 9b toward the side of the mouth portion 9c along the central axis O is also referred to as the upward direction, the opposite direction is also referred to as the downward direction, the direction along a straight line orthogonal to the central axis O is also referred to as the radial direction, the direction around the central axis O is also referred to as the circumferential direction, and a cross section including the central axis O is also referred to as a longitudinal section.

[0017] In the present embodiment, the refill container 1 is configured as a jar container having a height (width in the vertical direction) smaller than the width in the radial direction. Note that the refill container 1 is not limited to this, and may be configured as a bottle container having a height larger than the width in the radial direction.

[0018] The inner container 3 has an engaging wall 10 that extends in the circumferential direction and restricts the removal of the inner container 3 to the side (upper side) of the mouth portion 9c by engaging with the outer container 2, and an operation portion 12 that is provided radially inward of the engaging wall 10 and is continuous with the engaging wall 10 via a plurality of connecting portions 11 arranged in the circumferential direction. The operation portion 12 and the plurality of connecting portions 11 are bent into a convex shape that protrudes toward the side (lower side) of the bottom portion 9b as a whole.

[0019] The operation portion 12 is preferably disposed on the central axis O and has a plate shape such as a circular shape in plan view. The number and arrangement of the connecting portions 11 can be set as appropriate. Preferably, two connecting portions 11 are provided and are preferably provided symmetrically with respect to the central axis O. The engaging wall 10 may be configured to extend continuously over the entire circumference or may be configured to extend intermittently over the entire circumference.

[0020] The inner container 3 also has an inner wall portion 13 that has the engaging wall 10 at the end on the side (lower side) of the bottom portion 9b and extends in the circumferential direction, and an outer wall portion 14 that is provided radially outside the inner wall portion 13, extends in the circumferential direction, and is continuous with the inner wall portion 13 on the side of the mouth portion 9c rather than the plurality of connecting portions 11.

[0021] The outer container 2 has an outer peripheral wall 15 that is disposed radially outside the outer wall portion 14 so as to contact the outer wall portion 14, a bottom wall 17 that is continuous with the outer peripheral wall 15 and has an opening 16 that enables a pushing operation of the outer container 2 toward the side of the mouth portion 9c with respect to the operation portion 12, and a projecting piece 18 that extends from the bottom wall 17 toward the side of the mouth portion 9c and extends intermittently in the circumferential direction and engages with the engaging wall 10.

[0022] The inner peripheral surface of the engaging wall 10 engages with the outer peripheral surface of the projecting piece 18 so as to restrict the removal of the inner container 3 toward the side of the mouth portion 9c, preferably on both sides in the circumferential direction, at portions adjacent to each of the connecting portions 11 in the circumferential direction. The engagement is not limited to the engagement between convex portions as shown in the figure, and may be, for example, an engagement between a convex portion and a concave portion.

[0023] The replacement container 5 has a bottom wall portion 19, a peripheral wall portion 20 extending upward from the outer peripheral edge of the bottom wall portion 19 and extending in the circumferential direction, a flange portion 21 extending radially outward from the upper end of the peripheral wall portion 20, and an engaging portion 22 extending downward from the flange portion 21 and detachably engaging with the upper end of the inner wall portion 13. The bottom wall portion 19 and the peripheral wall portion 20 form a contents storage space 23 by their inner surfaces.

[0024] The opening 9c of the bottomed cylindrical portion 9 is formed by the upper part of the peripheral wall portion 20, the flange portion 21 and the engaging portion 22 of the replacement container 5, and the upper part of the inner wall portion 13 and the upper part of the outer wall portion 14 of the inner container 3.

[0025] The lid body 6 has a top wall 24 and a cylindrical wall 25 connected to the top wall 24. The packing 7 is positioned to cover the lower surface of the top wall 24 and is attached to the lid body 6. The lid body 8 can close the opening 9c by detachably engaging the inner circumferential surface of the cylindrical wall 25 with the outer circumferential surface of the opening 9c via a threaded portion 26, thereby bringing the packing 7 into close contact with the upper surface of the flange portion 21.

[0026] The refill container 1 may be configured such that the lid 8 is detachably engaged with the opening 9c by a structure other than the screw portion 26. Furthermore, the lid 8 is not limited to having a gasket 7 for sealing. The replacement container 5 is not limited to having an engaging portion 22, and may be configured to be detachably engaged with the inner container 3 by a portion other than the engaging portion 22. Furthermore, the replacement container 5 is not limited to having a flange portion 21.

[0027] As shown in Figures 2 and 3, when the lid 8 is removed, the operating part 12 receives a pushing operation toward the opening 9c, which elastically deforms the engagement wall 10 radially via the multiple connecting parts 11 to release the engagement. More specifically, the engagement wall 10 is elastically deformed radially outward at the portions adjacent to each connecting part 11 in the circumferential direction, loosening or releasing the engagement of the projection 18 with the outer circumferential surface.

[0028] Therefore, according to this embodiment, when the outer container 2 and the inner container 3 are made of different materials and separate disposal is required, the engagement between the inner container 3 and the outer container 2 can be released by pushing the operating part 12 of the inner container 3 toward the opening 9c when necessary, and the inner container 3 can be easily removed from the outer container 2 toward the opening 9c by the pushing force of that operation.

[0029] The present invention is not limited to the embodiments described above, and can be modified in various ways without departing from its essence.

[0030] Therefore, the refill container 1 of the above-described embodiment is modifiable as long as it is a refill container 1 having a container body 4 having an outer container 2 and an inner container 3, and a replacement container 5, wherein the outer container 2, inner container 3 and replacement container 5 together form a bottomed cylindrical portion 9 having a mouth 9c and a bottom 9b, and the inner container 3 has an engagement wall 10 that extends in the circumferential direction and restricts the removal of the inner container 3 toward the mouth 9c side by engaging with the outer container 2, and an operating portion 12 provided radially inward from the engagement wall 10 and connected to the engagement wall 10 via a plurality of connecting portions 11 arranged in the circumferential direction, and the operating portion 12 elastically deforms the engagement wall 10 radially in order to release the engagement via the plurality of connecting portions 11 when the operating portion 12 is pushed toward the mouth 9c side.

[0031] For example, the configuration in which the operating part 12 and the multiple connecting parts 11 are curved to form a convex shape that protrudes toward the bottom part 9b is not limited to this configuration; for example, the operating part 12 and the multiple connecting parts 11 may be configured to form a planar shape as a whole. In this case, for example, the operating part 12 may be configured such that when it is pushed toward the opening part 9c, the engaging wall 10 is elastically deformed radially inward at the portion radially adjacent to each connecting part 11, thereby loosening or releasing the engagement with the outer container 2 (for example, the inner circumferential surface of a projection 18 that extends upward from the bottom wall 17 radially outward from the engaging wall 10).
