Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap that is fitted and fixed to the mouth and neck of a container.

[0002]

2. Description of the Related Art For example, a cap in which a peripheral wall is hung from the outer periphery of a top wall with a pouring hole, and a ridge is provided on the inner surface of the peripheral wall so as to be fitted into a concave groove formed on the outer surface of the neck of a container body. Body and
There is known a cap including a lid body which is detachably fitted to the upper outer surface of the cap body and whose rear portion is integrally connected to the rear portion of the cap body through a thin hinge. Since the cap can be easily attached by driving and fitting and cannot be removed from the container body, it is widely attached to the mouth and neck of the container body such as a glass bottle and a plastic bottle.

By the way, recently,
In order to make effective use of limited resources, when disposing of waste, for example, the materials such as metal, synthetic resin, and glass are separated and disposed, and the recovered materials are reused. Therefore, when the material of the cap is different from that of the container body, the cap is removed from the container body when discarding the container body. However, since the conventional cap described above is fitted so as not to come off from the container body during use, it cannot be easily removed from the container body at the time of disposal, and there is a problem that it is not suitable for separate disposal. It was

It is an object of the present invention to provide a cap which is convenient for separation and disposal so that it does not come off from the container during use and can be easily removed from the container at the time of disposal.

[0005]

To achieve the above object, as a first means, a peripheral wall 6 is hung from the outer periphery of the pouring hole 3 or the top wall 4 with the pouring hole 3 forming portion, and the peripheral wall 6 is suspended. On the inner surface, a cap body 2 is provided, which is provided with a ridge 5 that fits into a groove provided on the outer surface of the neck portion of the container body, and on the outer surface of the upper portion of the cap body in a detachable manner, and the rear portion is capped. In the cap, which comprises a lid body 20 integrally connected to the rear portion of the body body through a thin hinge 23, and the cap body body and the lid body are integrally molded with a synthetic resin material, the cap body peripheral wall 6
A pair of left and right incisions 7, 7 are formed at appropriate intervals at the lower end, and thin rupture portions 8, 8 are vertically provided in parallel from the incisions to the peripheral wall portion above the protrusion 5.

[0006]

1 and 2 show an embodiment of a cap 1 of the present invention to be attached to the mouth and neck of a container body. The cap is composed of a cap body and a lid, and these members are integrally molded of synthetic resin material such as polyethylene.

As shown in FIG. 1, the cap body 2 has a peripheral wall 6 having a locking projection 5 formed vertically around the inner surface of the top wall 4 with a pouring hole 3 forming portion. On the front side of the peripheral wall, a pair of left and right notches 7 and 7 are formed at appropriate intervals at the lower end.
In addition, the thin wall portions 8 for breaking are vertically provided substantially in parallel from these cuts to the peripheral wall portion above the protrusion 5. The top wall 4 has a pouring tube 9 standing on the outer peripheral portion of the upper surface thereof, and the pouring hole 3 forming portion is provided in the pouring tube. The pouring hole 3 forming portion includes a cutting lid 11 surrounded by a thin-walled breaking portion 10 on a top wall portion in the pouring cylinder, and a pull ring 13 attached to an upper surface side portion of the cutting lid via a standing piece 12. The pulling ring is pulled and the cut-off lid 11 is broken and removed to open the pouring hole 3 in the top wall portion in the pouring tube 9. In the present embodiment, the top wall 4 is provided with the pouring hole 3 forming portion to close the pouring hole 3 of the cap body. However, by omitting the pouring hole 3 forming portion, the pouring hole 3 is formed. 3 may be opened beforehand in the center of the top wall 4.

Further, as shown in FIG. 1, the cap body 2 is
From the top wall outside the pouring tube 9 to the large diameter short tube 14 for fitting the lid
While standing up, from the lower surface of the outer peripheral edge of the thin-wall breaking portion 10,
A seal cylinder (15) that is fitted in a watertight manner on the inner surface of the mouth and neck of the container is hung. Further, a cutout portion 16 is formed at the upper end of the front side of the peripheral wall so that a finger can be easily put on a finger hanging plate described later. In the present embodiment, the thin portion 8 is formed by forming a groove having a V-shaped cross section on the inner surface of the peripheral wall 6 as shown in FIG. 2. The thin portion 8 has a V-shape on the outer surface of the peripheral wall 6. Groove may be provided, and the cross-sectional shape of the groove may be U-shaped.

From the outer periphery of the top plate 21 to the lid 20, the large-diameter short cylinder 14
A fitting wall 22 that is detachably fitted to the outer surface is provided so as to hang down, and a lower end of the rear side of the fitting wall is integrally connected to a rear upper end of the peripheral wall of the cap body via a thin hinge 23. . From the lower surface of the top plate 21 is hung a plug cylinder 24 that is detachably and watertightly fitted to the inner surface of the spout cylinder 9 of the cap body. Also, on the inner surface of the lower end of the fitting wall 22, a large diameter short tube of the cap body
13 Plural claw plates 25 that can be attached to and detached from the outer surface and can be forcibly fitted ...
Are attached at approximately equal intervals. Reference numeral 26 is a finger hook plate that projects outward from the front lower end of the outer surface of the fitting wall.

The operation of the cap 1 will be described below. When the peripheral wall 6 of the cap shown in FIG. 1 is fitted to the outer surface of the neck of the container body (not shown), the protrusion 5 of the cap body 5
Will fit into the groove of the neck of the container body, and the cap 1 will not come off from the container body. In this state, pinch the lower end of the peripheral wall between both notches 7 and pull it outward,
Alternatively, if a tip of a screwdriver or the like is inserted from the lower end of the peripheral wall between the notches 7 and 7 to the inner surface of the peripheral wall and the outer surface of the neck of the container body, and force is applied so that the lower end of the peripheral wall projects outward. The force is concentrated on the lower ends of the thin portions 8 and 8, and these thin portions are easily broken by a small force. After the rupture, the peripheral wall 6 of the cap body loosens the tightening on the neck portion of the container body. Therefore, when the cap body is pulled upward, the cap 1 is easily separated from the container body.

[0011]

The present invention is configured as described above, and a pair of left and right cuts 7 and 7 are provided at the lower end of the peripheral wall 6 of the cap body at appropriate intervals, and from the cuts, the protrusion 5 is formed.
Since the breaking thin portions 8, 8 are vertically provided substantially parallel to the upper peripheral wall portion, a force is applied to the lower end of the peripheral wall between the notches 7, 7 to deform the lower end of the peripheral wall so as to project outward. Since these thin parts can be easily broken with a small force, the peripheral wall of the cap body loosens the tightening on the neck portion of the container body by the breaking, and the cap 1 can be easily removed from the container body. When the cap 1 and the container body are made of different materials, they can be easily separated and discarded.
