Mode for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be illustrated and described with reference to the drawings.

[0016] As shown in FIGS. 1 to 5, in the first embodiment of the present invention, the container member 1 has a first member 1a and a second member 1b that respectively extend in the circumferential direction around a predetermined axis (referred to as the central axis O).

[0017] For convenience of explanation, the circumferential direction around the central axis O is simply referred to as the circumferential direction, the axial direction D along the central axis O is simply referred to as the axial direction D, the radial direction orthogonal to the central axis O is simply referred to as the radial direction, and a cross section including the central axis O is also referred to as a longitudinal section.

[0018] The container member 1 is configured as a container cap that is (for example, detachably) attached to the mouth of the container body. Note that the container member 1 is not limited to a container cap and can be configured as any member constituting the container.

[0019] The first member 1a is configured as an inner cap member that forms the inner part of the container cap. The second member 1b is configured as an outer cap member that forms the outer part of the container cap. Alternatively, the first member 1a may be configured as an outer cap member and the second member 1b as an inner cap member.

[0020] The first member 1a has a first positioning portion 2a, a first temporary fastening portion 3a, and a first hook portion 4a. The second member 1b has a second positioning portion 2b, a second temporary fastening portion 3b, and a second hook portion 4b.

[0021] The first member 1a has a primary protrusion 5a and a secondary protrusion 6a projecting radially from the primary protrusion 5a, and the second member 1b has a recess into which the primary protrusion 5a and the secondary protrusion 6a are inserted. The recess has a primary recess 5b and a secondary recess 6b recessing radially from the primary recess 5b, and the secondary protrusion 6a is inserted into the secondary recess 6b.

[0022] The first member 1a has a first protrusion 7a having a primary protrusion 5a and a secondary protrusion 6a, and a second protrusion 8a having a primary protrusion 5a and a secondary protrusion 6a. The second protrusion 8a has the same configuration as the first protrusion 7a except that its circumferential width W (linear distance in the illustrated example) is smaller than that of the first protrusion 7a. The second protrusion 8a is provided 180° opposite to the first protrusion 7a. The second member 1b has a first recess 7b having a primary recess 5b and a secondary recess 6b, and a second recess 8b having a primary recess 5b and a secondary recess 6b. The second recess 8b has the same configuration as the first recess 7b except that its circumferential width W is smaller than that of the first recess 7b. The second recess 8b is provided 180° opposite to the first recess 7b. The first protrusion 7a is inserted into the first recess 7b, and the second protrusion 8a is inserted into the second recess 8b. The second protrusion 8a may be configured to be the same as the first protrusion 7a except that its circumferential width W is larger than that of the first protrusion 7a, and the second recess 8b may be configured to be the same as the first recess 7b except that its circumferential width W is larger than that of the first recess 7b.

[0023] By making the circumferential widths W different in this way, it is easier to prevent the first member 1a and the second member 1b from being positioned 180° apart from each other. However, if it is acceptable for the first member 1a and the second member 1b to be positioned 180° apart from each other, it is not necessary to make the circumferential widths W different. The configuration may also consist of only one set of protrusions having a primary protrusion 5a and a secondary protrusion 6a, and recesses into which the protrusions are inserted, or three or more sets.

[0024] The first positioning portion 2a is formed by the circumferential end faces of the primary protrusions 5a of the first protrusion 7a and the second protrusion 8a, and the first hook portion 4a is formed by the stepped surfaces that form a radial step in the secondary protrusions 6a of the first protrusion 7a and the second protrusion 8a. The second positioning portion 2b and the second hook portion 4b are formed by the recesses of the first recess 7b and the second recess 8b. More specifically, the second positioning portion 2b is formed by the circumferential end faces of the primary recesses 5b of the first recess 7b and the second recess 8b, and the second hook portion 4b is formed by the stepped surfaces that form a radial step in the secondary recesses 6b of the first recess 7b and the second recess 8b.

[0025] By moving the first member 1a and the second member 1b relative to each other in the axial direction D until they reach the first arrangement shown in Figures 3 and 4, the first member 1a and the second member 1b are positioned relative to each other in the circumferential direction by the contact between the first positioning part 2a and the second positioning part 2b, and the first member 1a and the second member 1b are temporarily fixed relative to each other in the axial direction D by the contact between the first temporary fixing part 3a and the second temporary fixing part 3b with a mutual overlap T.

[0026] The first temporary fastening portion 3a is composed of the primary protrusions 5a of the first protrusion 7a and the second protrusion 8a, and the second temporary fastening portion 3b is composed of the primary recesses 5b of the first recess 7b and the second recess 8b. It is also possible to configure the first protrusion 7a or the second protrusion 8a by removing one or more of the functions of the first positioning portion 2a, the first temporary fastening portion 3a, and the first hook portion 4a.

[0027] Due to the contact with an overlap T, elastic deformation actually occurs in the first member 1a and the second member 1b, and a frictional force increased by the pressure contact is generated in the axial direction D at the contact point, thus achieving good temporary fastening in the axial direction D while maintaining circumferential positioning. Figure 4 shows the shape of the contact point superimposed in its shape before elastic deformation. The width of this overlap is the overlap T. In the first embodiment, the overlap T is set in the radial direction. The value of the overlap T can be set appropriately considering the application, shape, material, etc., of the container member 1.

[0028] By moving the first member 1a and the second member 1b in the axial direction D from the first arrangement to the second arrangement shown in Figure 5, the mutual engagement of the first hook portion 4a and the second hook portion 4b restricts the mutual movement of the first member 1a and the second member 1b from the second arrangement to the first arrangement, and the mutual positioning of the first member 1a and the second member 1b is maintained by the mutual contact of the first positioning portion 2a and the second positioning portion 2b in the circumferential direction.

[0029] Therefore, the positioning can be easily maintained by good temporary fastening with the overlap T, from the first arrangement state in which the first member 1a and the second member 1b are positioned to the second arrangement state in which changes in the arrangement state are restricted.

[0030] The first configuration is achieved when the first member 1a moves relative to the second member 1b in one direction D (referred to as the first axial direction D1). From the first configuration, the second configuration is achieved when the first member 1a moves further relative to the second member 1b in the first axial direction D1. When moving from the first configuration to the second configuration, the secondary convex portion 6a is inserted into the secondary concave portion 6b due to radial elastic deformation.

[0031] The first member 1a has a first contact surface 9a that forms a step in the radial direction. The first convex portion 7a and the second convex portion 8a each extend from the first contact surface 9a in the first axial direction D1 and protrude radially. The first temporary fixing portion 3a is provided on the portion of the primary convex portion 5a that is on the side of the first axial direction D1 side than the secondary convex portion 6a. The second member 1b has a second contact surface 9b that forms a step in the radial direction. The first recess 7b and the second recess 8b each extend from the second contact surface 9b in the first axial direction D1 and recess radially. The second temporary fixing portion 3b is provided on the portion of the primary recess 5b that is on the side of the second axial direction D2 side (opposite to the first axial direction D1) than the secondary recess 6b.

[0032] When the arrangement changes from the first to the second arrangement, the contact between the first contact surface 9a of the first member 1a and the second contact surface 9b of the second member 1b restricts further movement of the first member 1a and the second member 1b beyond the second arrangement. Therefore, changes in the arrangement in the second arrangement can be restricted more effectively.

[0033] As shown in Figures 6 to 10, the tightening allowance T may be configured to be set in the circumferential direction. In the second embodiment, the first temporary fastening portion 3a is formed by both circumferential end faces of the primary convex portion 5a, and the second temporary fastening portion 3b is formed by both circumferential end faces of the primary concave portion 5b. The other configurations are the same as in the first embodiment.

[0034] The first temporary fixing portion 3a is composed of portions that are provided on both circumferential ends of the primary convex portion 5a, positioned towards the first axial direction D1, and protruding in the circumferential direction. The second temporary fixing portion 3b is composed of portions that are provided on both circumferential ends of the primary concave portion 5b, positioned towards the second axial direction D2, and protruding in the circumferential direction. The first positioning portion 2a is composed of the entire circumferential ends of the primary convex portion 5a, and the second positioning portion 2b is composed of the entire circumferential ends of the primary concave portion 5b.

[0035] In the second embodiment, the first member 1a and the second member 1b are moved relative to each other in the axial direction D from the arrangement shown in Figure 8 to the first arrangement shown in Figure 9. This positions the first member 1a and the second member 1b relative to each other by the contact between the first positioning part 2a and the second positioning part 2b in the circumferential direction, and also temporarily fastens the first member 1a and the second member 1b relative to each other by the contact between the first temporary fastening part 3a and the second temporary fastening part 3b with a circumferential overlap T in the axial direction D.

[0036] Then, by moving the first member 1a and the second member 1b in the axial direction D from the first arrangement to the second arrangement shown in Figure 10, the mutual engagement of the first hook portion 4a and the second hook portion 4b restricts the mutual movement of the first member 1a and the second member 1b from the second arrangement to the first arrangement, and the mutual positioning of the first member 1a and the second member 1b is maintained by the mutual contact of the first positioning portion 2a and the second positioning portion 2b in the circumferential direction.

[0037] Therefore, the positioning can be easily maintained by good temporary fastening with the circumferential overlap T, from the first arrangement state in which the first member 1a and the second member 1b are positioned to the second arrangement state in which changes in the arrangement state are restricted.

[0038] The present invention is not limited to the embodiments described above, and can be modified in various ways without departing from its essence.

[0039] Therefore, the container member 1 of the above-described embodiment has a first member 1a and a second member 1b that extend in the circumferential direction around a predetermined axis, the first member 1a has a first positioning portion 2a, a first temporary fixing portion 3a and a first hook portion 4a, and the second member 1b has a second positioning portion 2b, a second temporary fixing portion 3b and a second hook portion 4b, and by moving the first member 1a and the second member 1b toward a first arrangement state in the axial direction D along the predetermined axis, the first member 1a and the second member 1b are positioned toward each other by the contact of the first positioning portion 2a and the second positioning portion 2b toward each other in the circumferential direction, and in the axial direction D, the first As long as the container member 1 is modified, it is possible to modify it as long as it is a container member 1, provided that the first member 1a and the second member 1b are temporarily fixed to each other by contact between the temporary fixing part 3a and the second temporary fixing part 3b with a mutual tightening allowance T, the movement of the first member 1a and the second member 1b from the second position to the first position is restricted by the mutual hooking of the first hook part 4a and the second hook part 4b, and the relative positioning of the first member 1a and the second member 1b is maintained in the circumferential direction by the mutual contact of the first positioning part 2a and the second positioning part 2b.
