Description

[Detailed description of the invention] [Industrial field of application] The invention consists of a bottle spout having a thread on its outer circumferential surface;
A jig used for assembling the visual body to the cap body in a pilfer-proof cap mechanism consisting of a crested cylinder-shaped cap body that is screwed onto the cap body and a visual body that is assembled to the lower inner surface of the peripheral wall of the cap body. It is related to.

[Conventional technology]

In order to solve the problem of conventional aluminum pilfer-proof caps with vertical slits and horizontal slits - visual confirmation is not easy - the applicant developed a design as shown in Fig. 2 prior to filing this application. An application was filed for a pilfer-proof cap mechanism.

This is because when the cap body 10 is loosened, the cap body 10 rises, the visual body 14 that locks the locking piece 18 to the protrusion of the mouthpiece 9 separates from the cap body 10, and the flange of the bottle body, etc. It is something that falls.
Once the visual body 14 has fallen, it cannot be reassembled by hand, thereby facilitating visual confirmation and further enhancing prevention of unauthorized opening.

[Problem that the invention attempts to solve]

The object of the present invention is to provide a jig that can easily assemble the visual body 14, which cannot be assembled by hand, to the cap body 10 in this pilfer-proof cap mechanism.

[Means for Solving the Problems] Therefore, the present invention is composed of a jig main body 1 and a fitting body 2.

The jig main body 1 has a cylindrical shape, and has an assembly hole 3 formed in its upper surface with a diameter approximately equal to the outer diameter of the lower end of the cap main body peripheral wall 11. A stepped portion 4 having a width not smaller than the wall thickness of the lower end surface is formed, and the diameter of the communicating hole 5 formed at the inner end of the stepped portion 4 is set larger than the diameter of the visual body 14 and the ring piece 12. Further, an insertion hole 6 having a diameter not smaller than the outer diameter of the visual body protrusion 13 is formed on the lower surface, and the upper peripheral end of the insertion hole 6 and the inner end of the stepped portion 4 are connected to form a guide surface 7 that extends upward. A tapered hole 8 that narrows was formed.

The diameter of the insertion hole is set not larger than the outer diameter of the visual body 14, so that it can be inserted freely into at least the insertion hole 6.

[Effect]

This will be explained with reference to FIG. This shows the state when the cap body 10 has already been assembled into the assembly hole 3, the visual body 14 has been inserted into the insertion hole 6, and the insertion body 2 has begun to press it. When the fitting body 2 is pressed from this state, the visual body 14 rises due to the pressing force, and the upper end of the protrusion 13 slides on the guide surface 7 and is gradually elastically deformed inward while being guided by the guide surface 7. By elastically deforming this guide piece, its diameter becomes smaller and it becomes possible to enter into the cap body 10. When the inset body 2 is further pressed, the visual body 1
4, the projecting piece 13 rises while sliding on the inner surface of the cap main body peripheral wall 11 and enters into the notch 19,
Assemble in place.

In the above operation, since the diameter of the assembly hole 3 is set approximately equal to the outer diameter of the lower end of the cap main body peripheral wall 11, the cap main body 10 can maintain a stable posture without wobbling. 14 is easy to assemble.

Furthermore, since the width of the stepped portion 4 is set not to be smaller than the thickness of the lower end surface of the peripheral wall 11, and the diameter of the communication hole 5 is set larger than the diameter of the visual body ring piece 12, the visual body 14 is It can be easily raised and assembled into a predetermined position without any hindrance.

〔Example〕

An embodiment of the present invention will be described with reference to FIG.

In this embodiment, the fitting body 2 is composed of a body portion 16 that enters into the insertion hole 6 and a head portion 17 that enters into the tapered hole 8. It is also possible to have a structure in which it enters into the cap body 10 (inside the cap body 10).

In addition, a grip part 15 is formed on the fitting body 2, and the assembly operation is performed by holding the grip part 15, thereby making the assembly operation easier to accomplish. The shape of the grip portion 15 is not limited, and may be appropriately set, such as circular or square. The external shape of the jig main body 1 is not similarly limited.

The taper angle of the guide surface 7 is set to such an extent that the protruding piece 13 can slide without receiving much resistance, and the surface is also smooth so that it can easily slide.

The jig according to the present invention can of course be operated by hand, but can also be operated by mechanizing it by attaching it to an assembly machine or the like.

Furthermore, although this jig according to the present invention is shown to be assembled to a cap body 10 having a notch 19 in the illustrated example, the structure of this cap body 10 is not limited; for example, the notch 19
Needless to say, it can also be used for attachment to a cap body 10 that does not have a cap.

[Effect of idea]

As described above, by using the jig of the present invention, the visual body 14, which cannot be assembled by hand, can be easily assembled to the cap body 10, which greatly contributes to improving productivity. .
