Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a safety cap that prevents unauthorized opening, etc., and aims to obtain a higher fraud prevention effect and ensure safety in use. It is something to do.

[Conventional technology]

Various types of safety caps have been put into practical use for the purpose of preventing unauthorized opening, but the basic structure is that a part of the cap body is placed in a bottle body and strongly attached to the bottle so that it cannot be removed. When the bottle is opened, the portion that is strongly locked to the bottle is cut and removed or separated from the main body of the cap.

[Problem that the invention attempts to solve]

With these conventional safety caps, even if they have already been opened, it may not be possible to identify them at first glance, or there may be unnecessary objects attached to the part that is used as the cap after opening. Many of them had drawbacks, such as the fact that this unnecessary material became dangerous. Furthermore, although there is no danger of the locking part being cut off, the locking force to prevent unauthorized opening is not sufficient, and as a result, there is a dissatisfaction that a reliable effect of preventing unauthorized opening cannot be obtained. Ta.

For example, the safety cap shown in Japanese Utility Model Application Publication No. 48-68063 is made entirely of a thin metal plate, so it can be strongly locked onto the bottle. In addition to exhibiting a strong ability to prevent unauthorized opening, the opening of the bottle is achieved by removing the score band part exposed on the outside, so it is possible to detect the presence or absence of the score band part on the cap body just by looking at it. It is possible to judge whether or not the cap body has already been opened. The problem is that when this cap body is used as a normal cap, there is a risk that the lower end surface may injure the user's hand, making it impossible to use the cap with peace of mind. There is.

Furthermore, the safety cap shown in Japanese Utility Model Application Publication No. 55-158850 is entirely molded from synthetic resin material, and the cut portion is exposed to the outside, so it is already open. It is possible to judge at a glance whether or not the cap has been cut, and sharp edges are not formed on the lower end surface, which is the cut end surface of the cap body that is used as the cap even after opening, because of this cutting. Although it has the advantage of being safe to use as an opening/closing cap,
This safety cap is assembled to the bottle body using the elasticity of the synthetic resin material used to make the cap, so it has a strong locking mechanism that ensures reliable and strong prevention of unauthorized opening. Therefore, there was a problem in that the effectiveness in preventing unauthorized opening was significantly lower than that of the metal safety cap described above.

The problem with this conventional safety cap is that this type of safety cap is required to have sufficient strength to prevent unauthorized opening and to be safe in use, but metal caps do not have sufficient strength to prevent unauthorized opening. On the other hand, synthetic resin products have the disadvantage of lacking safety in use, but at the cost of being safe in use, they have sufficient safety to prevent unauthorized access. This is due to the unsuitability of the material from which the safety cap is made, either not providing sufficient strength or resulting in extremely complex structures to provide sufficient strength.

The present invention was devised to solve the problems and inconveniences of the conventional examples described above, and consists of a metal material that exhibits a strong ability to prevent unauthorized access, and a synthetic resin material that provides sufficient safety in use. The technical objective is to provide a safety cap that can exhibit a strong anti-unauthorized opening effect and a high level of safety in use by combining the following.

[Means for solving problems]

The means of the present invention includes a main body part 1 in the shape of a capped cylinder (see Fig. 2) formed of a thin sheet of soft metal such as aluminum, and a protruding peripheral part provided at the lower end of the outer peripheral surface of the mouth part 17 of the bottle body 15. A cylindrical fixing part 2 made of a thin sheet of soft metal such as aluminum is provided with a locking piece 3 at the lower end that locks onto the collar piece 16 from below, and a thin wall is provided between the lower end of the main body part 1 and the upper end of the fixing part 2. Part 5
It consists of a connecting ring piece 4 made of soft synthetic resin that is connected via a connecting ring piece 4, and a knob piece 7 that protrudes outward is provided on a part of the connecting ring piece 4, and a connection piece near this knob piece 7 is provided. The cutting part 8 is formed in the ring piece 7 portion.

[Effect]

The main body part 1 that covers the mouth part of the bottle body 15 and the fixing part 2 that locks onto the flange piece 16 of the bottle body 15 as a safety cap to ensure its assembly are made of soft metal thin plate, so that the bottle Assembling the safety cap to the body 15 can be easily achieved with sufficient strength by simply fixing the lower end of the fixing part 2 to the collar piece 16 by caulking.

This safety cap can be opened by strongly pulling the outwardly protruding knob piece 7, cutting the thin wall part 5 and removing the connecting ring piece 4, and then opening the main body part 1.
This is achieved by separating the fixed part 2 from the fixed part 2.

When removing the connecting ring piece 4, the thin part 5 to be cut is made of soft synthetic resin, so the soft synthetic resin will be exposed at the cut location.
This prevents the formation of hard, sharp edges at the cutting location.

When the connecting ring piece 4 is cut and removed, since a cut part 8 is formed near the knob piece 7, the tensile force acting on the knob piece 7 is concentrated on the thin wall part 5 located at the cut part 8. Thus, the thin portion 8 can be cut reliably and easily. Also, since the body part 1 is formed of a thin sheet of soft metal like the conventional pill-proof cap, the body part 1 is formed on the mouth part 17 of the bottle body 15 when it is assembled to the mouth part 17. The screw thread that is screwed into the screw thread can be bent and lowered by pressing.

〔Example〕

In the illustrated implementation, the main body part 1 and the fixing part 2 are
In order to achieve connection with the connecting ring piece 4 through the thin wall part 5, the lower end of the main body part 1 and the upper end of the fixing part 2 are the same as the connecting ring piece 4. Molded from synthetic resin material.
That is, a ring-shaped assembly ring 9 made of synthetic resin is assembled and fixed to the lower end of the main body 1, and the assembly ring 9 and the metal main portion of the main body 1 are connected as follows. The lower end of the main body part buried in the assembly ring 9 is folded outward to form a bent end 11, and the folded position of this bent end 11 strengthens the connection between the main body part and the assembly ring 9. There is. Similarly, a ring-shaped assembly ring 10 made of synthetic resin is assembled and fixed to the upper end of the fixing part 2, and the assembly ring 10 and the main body of the fixing part 2 are connected to each other. attachment ring 10
The upper end portion of the main body part buried inside is folded back outward to form a bent end 12, and the folded posture of this bent end 12 makes the connection between the main body part and the assembly ring 10 strong.

In the case of this illustrated embodiment, both the assembly rings 9, 10, the connecting ring piece 4, and the thin wall portion 5 are formed by forming the lower end of the main portion of the main body portion 1 and the upper end of the main portion of the fixing portion 2 as part of the mold. By insert molding, the molding can be easily accomplished, and the main portion of the main body portion 1 and the main portion of the fixing portion 2, which are separate objects, can be integrally assembled.

The cutting part 8 is formed by removing a part of the connecting ring piece 4, and this cutting part 8 concentrates the cutting force generated by the action of the pulling force on the knob piece 7 on the thin part 5. Any configuration may be used as long as the configuration can be made to work.

The illustrated embodiment in FIG. 2 shows a case where the safety cap according to the present invention is constructed as a mere overcap, and a certain amount of gap is created between the safety cap and the lid body 18 covered by the safety cap according to the present invention. The dimensions of the safety cap are set so that the rotational force as an external force acting on the safety cap will cause the cover body 1 to
8 so as not to be transmitted.

In addition, in the case of the embodiment shown in FIG. 3, the safety cap according to the present invention is configured to be used with a general pill-proof cap, and the mouth tube part 1
7, the locking piece 3 is plastically worked and at the same time the thread 13 that is screwed into the mouth tube part 17 is plastically worked. In this embodiment, the main body part 1 is Since it will be used as an opening/closing cap, it is preferable to assemble and fix a gasket 14 to the lower surface of the top plate of the main body 1.

[Effect of idea]

As is clear from the above explanation, the safety cap according to the present invention has a locking piece that locks onto the flange of the bottle from below, which is formed at the lower end of the metal fixing part. Can be strongly locked,
This strongly prevents unauthorized opening and increases safety. Also, since the connecting ring piece is molded from soft synthetic resin, when the connecting ring piece is cut and removed for opening, it will not be molded. There are no sharp or hard corners formed on the cut end surface, which is the lower end of the main body, and this makes it possible to obtain high safety when using the main body after opening as an opening/closing cap, and furthermore, it is possible to prevent tampering. It exhibits many excellent effects, such as not complicating the structure for preventing opening and being easy to manufacture.
