JP 2019-26281 A

When it is necessary to separate the process of positioning the first and second members (the process of bringing them into a first positioning state) from the process of restricting changes in the positioning state of the first and second members (for example, attaching the first and second members to each other) (the process of bringing them into a second positioning state) and to insert another process between these processes, there is a risk that the positioning cannot be maintained in that other process.

The following describes an embodiment of the present invention with reference to the drawings.

As shown in Figures 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 each extend in a circumferential direction around a predetermined axis (referred to as a central axis O).

For ease of explanation, the circumferential direction going around the central axis O is also referred to simply as the circumferential direction, the axial direction D along the central axis O is also referred to simply as the axial direction D, the radial direction perpendicular to the central axis O is also referred to simply as the radial direction, and the cross section including the central axis O is also referred to as the longitudinal cross section.

The container member 1 is configured as a container cap that is attached (e.g., detachably) 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 that constitutes a container.

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

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.

The first member 1a has a primary convex portion 5a and a secondary convex portion 6a that protrudes radially from the primary convex portion 5a, and the second member 1b has a recess into which the primary convex portion 5a and the secondary convex portion 6a are inserted. The recess has a primary recess 5b and a secondary recess 6b that is recessed radially from the primary recess 5b, and the secondary convex portion 6a is inserted into the secondary recess 6b.

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

By making the circumferential widths W different in this way, it is possible to easily prevent the first member 1a and the second member 1b from being positioned with a 180° offset from each other. Note that in cases where it is acceptable for the first member 1a and the second member 1b to be positioned with a 180° offset from each other, it is not necessary to make the circumferential widths W different. The configuration may have only one set or three or more sets of a convex portion having a primary convex portion 5a and a secondary convex portion 6a and a concave portion into which the convex portion is inserted.

The first positioning portion 2a is formed by both circumferential end faces of the primary convex portion 5a of the first convex portion 7a and the second convex portion 8a, and the first hook portion 4a is formed by step surfaces that form a step in the radial direction in the secondary convex portion 6a of the first convex portion 7a and the second convex portion 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 both circumferential end faces of the primary recess 5b of the first recess 7b and the second recess 8b, and the second hook portion 4b is formed by step surfaces that form a step in the radial direction in the secondary recess 6b of the first recess 7b and the second recess 8b.

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 state 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 abutment of the first positioning portion 2a and the second positioning portion 2b, and the first member 1a and the second member 1b are temporarily fixed to each other in the axial direction D by the abutment of the first temporary fixing portion 3a and the second temporary fixing portion 3b with a tightening margin T.

The first temporary fastening portion 3a is formed by the primary protrusions 5a of the first protrusion 7a and the second protrusion 8a, and the second temporary fastening portion 3b is formed by the primary recesses 5b of the first recesses 7b and the second recesses 8b. Note that the first protrusion 7a or the second protrusion 8a may be configured without one or more of the functions of the first positioning portion 2a, the first temporary fastening portion 3a, and the first hook portion 4a.

The contact with the clamping margin T actually causes elastic deformation of the first member 1a and the second member 1b, and the frictional force in the axial direction D is increased by the pressure contact at the contact point, so that a good temporary fastening in the axial direction D is achieved with the circumferential positioning set. Note that FIG. 4 shows the shape of the contact point overlapped with the shape before elastic deformation. The width of this overlap is the clamping margin T. In the first embodiment, the clamping margin T is set in the radial direction. The value of the clamping margin T can be set appropriately taking into account the application, shape, material, etc. of the container member 1.

By moving the first member 1a and the second member 1b relative to each other in the axial direction D from the first arrangement state to the second arrangement state shown in FIG. 5, the first hook portion 4a and the second hook portion 4b hook each other to restrict the movement of the first member 1a and the second member 1b relative to each other from the second arrangement state toward the first arrangement state, and the first member 1a and the second member 1b are maintained relative to each other in the circumferential direction by the abutment of the first positioning portion 2a and the second positioning portion 2b against each other.

Therefore, the positioning can be easily maintained by the good temporary fastening provided by the clamping margin 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.

The first member 1a moves relative to the second member 1b in one side of the axial direction D (referred to as the first axial direction D1) to enter a first arrangement state, and the first member 1a further moves from the first arrangement state in the first axial direction D1 relative to the second member 1b to enter a second arrangement state. When moving from the first arrangement state to the second arrangement state, the secondary convex portion 6a is inserted into the secondary concave portion 6b due to radial elastic deformation.

The first member 1a has a first abutment 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 abutment surface 9a in the first axial direction D1 and have a convex shape that protrudes in the radial direction. The first temporary fastening portion 3a is provided in a portion of the primary convex portion 5a that is closer to the first axial direction D1 than the secondary convex portion 6a. The second member 1b has a second abutment surface 9b that forms a step in the radial direction. The first recess 7b and the second recess 8b each extend from the second abutment surface 9b in the first axial direction D1 and have a concave shape that is concave in the radial direction. The second temporary fastening portion 3b is provided in a portion of the primary recess 5b that is closer to the opposite side of the first axial direction D1 (referred to as the second axial direction D2) than the secondary recess 6b.

When the first arrangement state is changed to the second arrangement state, the first abutment surface 9a of the first member 1a and the second abutment surface 9b of the second member 1b come into contact with each other, thereby restricting further movement of the first member 1a and the second member 1b beyond the second arrangement state. Therefore, the change in the arrangement state in the second arrangement state can be more effectively restricted.

As in the second embodiment shown in Figures 6 to 10, the tightening margin T may 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.

The first temporary fastening portion 3a is formed by a portion that is provided on both circumferential end faces of the primary convex portion 5a toward the first axial direction D1 and protrudes in the circumferential direction. The second temporary fastening portion 3b is formed by a portion that is provided on both circumferential end faces of the primary concave portion 5b toward the second axial direction D2 and protrudes in the circumferential direction. The first positioning portion 2a is formed by the entire circumferential end faces of the primary convex portion 5a, and the second positioning portion 2b is formed by the entire circumferential end faces of the primary concave portion 5b.

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 FIG. 8 to the first arrangement shown in FIG. 9, whereby the first positioning portion 2a and the second positioning portion 2b abut against each other in the circumferential direction, and the first member 1a and the second member 1b are temporarily fastened to each other in the axial direction D by the abutment of the first temporary fastening portion 3a and the second temporary fastening portion 3b with a circumferential tightening margin T.

Then, by moving the first member 1a and the second member 1b relative to each other in the axial direction D from the first arrangement state to the second arrangement state shown in FIG. 10, the first hook portion 4a and the second hook portion 4b hook together, restricting the movement of the first member 1a and the second member 1b relative to each other from the second arrangement state toward the first arrangement state, and the first member 1a and the second member 1b are maintained relative to each other in the circumferential direction by the abutment of the first positioning portion 2a and the second positioning portion 2b against each other.

Therefore, the positioning can be easily maintained by the good temporary fastening provided by the circumferential clamping margin 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.

The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the invention.

Therefore, the container member 1 of the above-mentioned embodiment has a first member 1a and a second member 1b each extending in a circumferential direction around a predetermined axis, the first member 1a has a first positioning portion 2a, a first temporary fastening portion 3a, and a first hook portion 4a, and the second member 1b has a second positioning portion 2b, a second temporary fastening portion 3b, and a second hook portion 4b, and by moving the first member 1a and the second member 1b relative to each other in the axial direction D along the predetermined axis until they reach a first arrangement state, the first member 1a and the second member 1b are positioned relative to each other in the circumferential direction by the abutment of the first positioning portion 2a and the second positioning portion 2b with each other, and the first temporary fastening portion 3a and the second hook portion 4b are positioned relative to each other in the axial direction D along the predetermined axis. The first member 1a and the second member 1b are temporarily fixed to each other by the abutment of the fastening portion 3a and the second temporary fixing portion 3b with a tightening margin T, and by moving the first member 1a and the second member 1b from the first arrangement state to the second arrangement state in the axial direction D, the first hook portion 4a and the second hook portion 4b hook each other to restrict the movement of the first member 1a and the second member 1b from the second arrangement state toward the first arrangement state, and the positioning of the first member 1a and the second member 1b in the circumferential direction is maintained by the abutment of the first positioning portion 2a and the second positioning portion 2b to each other. This can be modified as long as it is a container member 1.
