[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for opening and closing a container such as a bottle.

[0002]

2. Description of the Related Art Conventionally, a container opening and closing device as shown in FIG. 5 has been widely used. Since this invention is an improvement of the above-mentioned conventional switchgear, the conventional switchgear will be described first.

In FIG. 1, a is an inner cover made of synthetic resin, b is an outer cylinder, and c is an inner cylinder. And these two cylinders b and c
Is mounted in such a manner as to sandwich the mouth e of the container d. f
Is a protruding engaging portion formed on the inner surface of the outer cylinder b, and is engaged with a concave engaging portion g formed on the outer surface of the mouth e.

[0004] Reference numeral h denotes an opening wall that blocks the flow of fluid, and has an endless fissure i formed therein. j is this fissure i
Is a tearing member formed on the mouth wall h.
k indicates an outer lid. Reference numeral 1 denotes a protrusion protruding outward from a portion m corresponding to the lower end of the outer cylinder b.

[0005] A user such as a consumer removes the outer lid k, pulls the tearing member j upward, cuts off the fissure i, forms a through-hole therein, and pours out the content liquid. This switchgear is sealed until the first use, so it is safe and can be used with confidence.

[0006]

However, the above-mentioned conventional switchgear has the following drawbacks. It is used by pouring out the contents liquid as described above and, when consumed, its container d
May be collected and used. In this case, the inner lid a
Is difficult to remove from the container d. The reason for this is that there is no place to open the outer cylinder b, as can be easily understood from FIG. The lower end of the outer cylinder b is covered by the projection l, so that there is no place to open the bottle.

[0007] The present invention has been made to solve such a problem, and its object is to remove the used container when it is difficult to remove the container normally, to prevent unauthorized refilling, and to collect used containers. It is an object of the present invention to provide a container opening / closing device from which a cap can be easily removed from a container.

[0008]

The present invention which achieves the above object will be described with reference to a synthetic resin inner lid 3 attached to a mouth 2 of a container 1; an outer cylinder 4 and an inner lid 3 of the inner lid 3. An attachment portion 6 for holding the mouth portion 2 formed by a cylinder 5; an mouth wall 7 formed inside the attachment portion 6 for blocking the passage of fluid; an endless crack formed on the mouth wall 7 Groove 8; Fissure 8
Tearing member 9 provided on the inside of the outer wall 4 and on the mouth wall 7; a locking portion 11 provided on the inside of the outer cylinder 4 and locking to the concave engaging portion 10 of the container 1 and projecting inward; A ring 14 having a knob 13 integrally provided at a lower end of the outer cylinder 4 via a circumferential weakening line 12; a vertical weakening line 15 provided near the knob 13 of the ring 14; An outer lid 16 mounted on the inner lid 1; provided so as to protrude outward from a portion of the mouth 2 corresponding to a lower end of the ring 14;
In addition, the engaging portion 10 is locked in cooperation with the engaging portion 10.
Through the lower end of the outer cylinder 4 and the weakening line 12
Protruding portion for clamping the ring 14 provided together
18; a container opening and closing device characterized by comprising :

[0009]

First, the user removes the outer lid 16, pulls the tearing member 9 upward, cuts the fissure 8 and forms a through-hole therein, and pours out the contents. When the contents are consumed and this container is to be collected, the operator of the collection needs to pick the ring 14
3. Pick 3 and pull it in the circumferential direction. Then, the vertical weakening line 15 formed near the knob 13 is torn, and then the circumferential weakening line 12 is torn.
Thus, the ring 14 is removed.

[0010] When the ring 14 is removed, a space is created in that part. Therefore, the worker positions the push-up portion of the bottle opener in this space and applies it to the lower end of the outer cylinder 4 of the inner lid 3. This is pushed upward to release. Thereby, it can be easily opened.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a container, for example, a bottle. 2 indicates the mouth. Reference numeral 3 denotes an inner lid, which is formed of a synthetic resin and is attached to the mouth portion 2. Reference numeral 4 denotes an outer cylinder, which is provided with a locking portion 11 which protrudes inward, and is locked to an engaging portion 10 formed in a concave shape on the outer periphery of the mouth portion 2. The outer cylinder 4 is attached together with the inner cylinder 5 to the mounting portion 6.
Are formed, and the mouth portion 2 is held by the attachment portion 6. Reference numeral 7 denotes a mouth wall integrally formed inside the mounting portion 6, and an endless groove 8 is formed in the mouth wall.

A pull ring-shaped tearing member 9 is provided inside the groove 8 and on the mouth wall 7. Reference numeral 14 denotes a ring as shown in FIGS. 1 to 3, which is integrally provided at a lower end of the outer cylinder 4 via a circumferential weakening line 12. Reference numeral 13 denotes a knob provided on the ring 14,
In the vicinity, a weakening line 15 in the vertical direction is formed on the left side of the base 20 as an example. Each of the weakening lines 15 together with the weakening line 12 is a weakened portion which is easily formed like a fissure or a perforation formed in the fissure. An outer lid 16 is screwed to the inner lid 3. However, the outer lid 16 is hinged.
There is no problem.

Reference numeral 18 denotes a projecting portion of the container 1, and 21 denotes a connecting piece. Reference numeral 22 denotes an ejection tube. The operation of this embodiment is almost the same as that of the present invention described above, except that the knob 13 is used to cut off the weakening line 15 and the weakening line 12,
After removing the ring 14, as shown in FIG.
The upper cover 3 is applied to the lower end 26 of the outer cylinder 2 with the push-up portion 25 and is pushed upward to open the inner lid 3. In this case, this removal is performed while the outer lid 16 is attached.
There is no problem even if it is open outside.

[0014]

According to the present invention, a ring 14 having a knob 13 is provided below the outer cylinder 4 and integrally via a circumferential weakening line.
The container 1 is provided with a protruding portion 18 which protrudes outward under the container 1, so that it is difficult to remove the cap in a normal case, so that it is possible to prevent impropriety, and at the time of collection of the container, It can be easily removed. Again
The protruding portion 18 cooperates with the engaging portion 10 to form the engaging portion 10.
Lower end of the outer cylinder 4 and the weakening line 12
To be clamped based on the ring 14 provided through
When the cap is plugged, the outer cylinder 4 is
The diameter of the protrusion on the top is enlarged, and it is forcibly overtaken
Next, the vibration of the collision at the time of fitting to the above-mentioned engaging portion with a small diameter is described.
To prevent the weakening line 12 from being damaged.
