Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a main stopper guarantee cap in which an outer cap and an inner cap are connected with a three-point hinge.

(Prior Art) Conventionally, a container fitted with a stopper having a perforating protrusion for opening a sealing part of the mouth part with respect to a cap lid screwed onto the mouth part is known as Japanese Utility Model Publication No. 10280/1980. ing.

(Problems to be solved by the invention) The perforation protrusion provided on the stopper of the conventional container as described above is normally exposed to outside air,
Therefore, the seal is opened with something contaminated by outside air, which is unsanitary.

Further, after the seal is opened, the lid of the cap lid is opened and closed using the plug, and the plug is removed from the cap lid, so the plug is likely to scatter.

(Means for solving the problem) Therefore, the technical problem of this proposal is to create a main stopper guarantee cap that is not contaminated by outside air, has a piercing protrusion that also serves as a seal when not in use, and does not cause the outer lid to dissipate. The technical means of the present invention to solve this technical problem is to use a three-point hinge that allows the outer cap to be opened and closed with respect to the inner cap that is detachably attached to the container spout. The cap is connected to the top plate of the inner cap facing the container spout, and is provided with a removable piercing protrusion capable of opening the sealed portion of the container spout, thereby covering the opening. be.

(Operations and effects of the invention) The present invention is a cap with three hinges and an opening function, and the sealing part of the container spout is usually covered with a piercing protrusion.
Since the piercing protrusion is further covered by the outer cap and capped on the container, the piercing protrusion is not contaminated by the outside air, and since the piercing protrusion covers the sealing part, it is double sealed together with the sealing part. The cap can maintain its sealing function at all times without being unnecessarily opened by external pressure, and when in use, the entire cap is removed from the container spout, and the piercing protrusion is used to seal the container spout. It opens, and when dispensing the contents, the inner cap is capped on the container spout with the piercing protrusion cut off, and the outer cap is opened. It is connected with a 3-point hinge so that it will not dissipate, and when pouring directly from the container spout, you can simply cap it without cutting off the piercing protrusion, and the container spout will be covered with the piercing protrusion, allowing the contents to be poured directly from the container spout. The present invention is characterized in that it is possible to obtain a main stopper guarantee cap that has an opening function that does not require the preparation of a separate opening tool when opening the cap without leaking liquid.

(Example) The embodiments shown in the drawings will be described below.

The main stopper guarantee cap of the present invention has an outer cap 1 and an inner cap 2 connected by a three-point hinge part a, which are integrally molded by injection molding.

The three-point hinge part a has a wide and long connecting part _a1 that reaches up to the top surface of the outer cap 1, and a narrow and short connecting part a2 and a on both sides of it that extends to the side surfaces that do not reach the top surface of the outer cap ₁ . It consists of ₃ .

Therefore, the connecting part a ₁ has an L-shaped cross section, which forms a hinge action together with the other short connecting parts a ₂ and a ₃ .

According to this three-point hinge part a, when the outer cap 1 is opened outward, the short connecting parts a ₂ and a ₃ are bent from the boundary between the inner cap and the outer cap, and the connecting parts
a ₁ is bent from the connection between the inner and outer caps, and the connection a ₁ can be bent beyond its dead center to keep the outer cap 1 in the open position.

A screw tube 4 is protruded from inside the inner cap 2 and can be screwed into a screw 3b of a spout 3a of a container 3, for example, a metal tube.
The top plate 2 of the inner cap 2 faces the sealing part 3c of a.
There is an opening 5 in a, which is covered with a pyramid-shaped piercing protrusion 6.

Reference numeral 7 denotes a thin connecting portion that connects the inner cap opening 5 and the piercing projection 6, and by using this, the piercing projection 6 can be cut out to open the opening 5.

Reference numeral 8 denotes a shielding cylinder protruding from the inside of the outer cap 1, and is provided at a position to cover the piercing protrusion 6.

Reference numeral 9 designates a knob on the outer cap 1, and a groove 10 is provided on the outer periphery of the corresponding inner cap 2 to make the knob easier to grasp.

Since the present invention is constructed as described above, the cap is attached to the container spout 3a as shown in FIG. 1 before opening the container.

In this state, the sealing portion 3c of the container spout, that is, the seal, is covered by the piercing protrusion 6, and the piercing protrusion 6 is covered by the outer cap 1.
The hermeticity of the container is maintained. When opening the container, first loosen the screw from the container spout 3a and remove the entire cap, then use the knob 9 to open the outer cap 1 from the inner cap 2, turn the cap over, and open the second cap.
As shown in the figure, the sealing portion 3c of the container spout 3a is opened using the piercing protrusion 6.

After opening the container as described above, cut out the piercing protrusion 6 from the thin wall portion 7, and then cap the inner cap 2 on the container spout 3a as shown in FIG.
The outer cap 2 is opened and the liquid inside is poured out.

When pouring directly from the container spout 3a, there is no need to cut out the piercing protrusion 6, and in this case, the piercing protrusion 6 covers the spout 3a and the liquid content does not leak out.

In addition, in the illustrated example, the sealing portion of the container spout is shown as being integral with the spout, but it may be sealed with a sealing material.

Further, the inner cap may not be formed into a dual inner and outer cylinder, but may be a single cylinder, and a thread may be directly formed therein.
