Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid pouring tap mounted on a mouth and neck of a container body.

[0002]

2. Description of the Related Art As a commonly used liquid spout made of a synthetic resin, a liquid spouting plug in which a lower end portion of a cap peripheral wall is connected via a thin hinge to an upper end portion of a mounting cylinder fitted to the outer surface of the neck of a container body is known. Have been.

[0003]

SUMMARY OF THE INVENTION Separation and recovery of waste is desired from the viewpoint of recycling in consideration of environmental load reduction. For this separation and recovery, a liquid injection stopper made of synthetic resin, It is desirable that the container can be easily separated from a container formed of a material other than a synthetic resin material such as a metal. However, since the liquid pouring stopper is for closing the opening and closing of the mouth and neck of the container, it is not preferable that the liquid can be easily removed from the container, which may make it difficult to separate and collect the liquid. Was.

[0004] The liquid pouring tap according to the first aspect of the present invention is firmly attached in the same manner as in the prior art by forming a thin wire for breaking continuous from the upright plate on the mounting cylinder tube wall to be attached to the mouth and neck of the container body. The purpose of the present invention is to facilitate separation and recovery by allowing the liquid spouting tap to be easily removed from the container at the time of disposal.

[0005] The liquid pouring tap according to claim 2 has the problem to be solved by the liquid pouring tap according to claim 1, and further includes a fitting cylinder fitted to the inner surface of the neck of the container body. In spite of making the attachment of the stopper more firm, it is intended to make it easier to break the thin wire for breaking by cutting off a part of the inward flange.

[0006]

As a first means, there is provided a liquid pouring plug in which a lower end of a cap peripheral wall 4 is connected via a thin hinge 3 to an upper end of a mounting cylinder 2 fitted to the outer surface of a container body neck 1. In the above, the thin hinge 3 is formed by even-numbered hinges 3a, 3b, 3c, 3d arranged in the circumferential direction, and a cap peripheral wall between a pair of adjacent thin hinges 3b, 3c located in the center among these hinges. The lower part of the four parts is cut off in a rectangular shape from the upper end part, and the upright plate 6 is made to rise into the cut part 5 of the cap peripheral wall 4 from the upper surface of the wall part of the mounting cylinder between the pair of thin hinges. Standing plate 6
The thin thin wire 7 for breaking in the vertical direction was formed from the lower end on both sides of the to the lower end of the wall of the two mounting cylinders.

As a second means, there is provided a fitting cylinder 9 having the first means and adapted to fit from the lower surface of the inner peripheral portion of the inward flange 8 attached to the upper end of the mounting cylinder 2 to the inner surface of the neck of the container body. And a part of the outer peripheral portion of the inward flange was cut in an arc shape so as to be continuous with the lower end of the upright plate 6.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a liquid pouring tap according to the present invention will be described with reference to the drawings. First,
Explaining a conventionally known portion, the mounting cylinder 2 is fitted to the outer surface of the container body neck portion 1 formed of a material other than a synthetic resin material such as metal or glass via an uneven engagement means so that it cannot be pulled out, and The lower end of the cap peripheral wall 4 is connected to the upper end of the mounting cylinder 2 via a thin hinge 3.

In the present invention, the thin hinge 3 is formed by four-point hinges 3a, 3b, 3c, and 3d arranged in the circumferential direction, and a pair of adjacent thin hinges 3b located in the center of the four-point hinges. The upper and lower portions of the cap peripheral wall 4 between 3c and 3c are cut in a vertically long rectangular shape to form an opening 5 having an upper surface closed and a lower surface opening. Further, the upright plate 6 is erected into the opening 5 from the upper surface of the wall of the mounting cylinder 2 between the pair of thin hinges 3b, 3b, and from the lower ends on both sides of the erection plate 6 to the lower end of the mounting cylinder 2 cylinder wall. A thin wire 7 for breaking extending in the up-down direction is formed.

According to a second aspect of the present invention, an inward flange is protruded from the upper end of the mounting cylinder, and the lower surface of the inward flange is placed on the upper surface of the neck of the container body. From the inner peripheral lower surface to the inner surface of the mouth and neck of the container, watertight,
In addition, it is possible to vertically attach the fitting tube 9 to which the fitting tube 9 is fitted so that it cannot be pulled out, so that the mounting tube 2 is more firmly attached to the mouth and neck of the container body. In order to easily break the thin wire 7 for breaking by pulling,
An arc-shaped elongated opening 10 extending in the circumferential direction is formed in a part of the outer peripheral portion of the inward flange 8 so as to be continuous with the lower end of the upright plate 6. In the illustrated example, the thin hinge 3 is formed as a four-point hinge, but is not limited to this, and may be formed as a two-point hinge.

The liquid pouring tap of the present embodiment further has a pouring cylinder with a pull ring. In the following, this will be described. The pouring tube 11 rises from the outer peripheral portion of the top wall of the fitting tube 9, and further rises from the upper end of the cylindrical wall to a tapered peripheral wall 12 having a small diameter and an arc-shaped vertical cross section. . Further, the dispensing cylinder 11
A removing plate portion 13 is formed by providing a break line around the lower surface of the top wall portion of the fitting tube 9 inside, and a rod portion 14 with a pull ring stands up from the outer peripheral edge of the removing plate portion.

Reference numeral 15 denotes a sealing cylinder which hangs down from the center of the lower surface of the cap top wall 16 and has a lower end tapered around the peripheral wall 12.
It is in contact with the inner peripheral surface. Reference numeral 17 denotes a plurality of reinforcing plates protruding from the inner surface of the seal cylinder 15 closest to the upright plate 6.

Next, the operation of this embodiment will be described.
To pour out the liquid, after the cap is opened, the pull ring is pulled upward to remove the removing plate 13, and then the container is tilted. In order to discard the container, the upright plate 6 may be pulled downward with the cap closed, and the breaking thin wire 7 is broken, and the wall of the mounting tube 2 between the two thin wires is separated from the mounting tube 2. The mounting tube 2 and the fitting tube can be easily removed from the body / neck portion 1.

[0014]

According to the liquid pouring tap of the first aspect, the thin wire for breaking, which is continuous with the upright plate, is formed on the wall of the mounting cylinder to be mounted on the mouth and neck of the container body, so that the mounting is firm. Nevertheless, at the time of disposal, the liquid pouring tap can be easily removed from the container body, so that the separation and collection can be promoted.

In the liquid spouting plug according to the second aspect, the fitting tube to be fitted into the inner surface of the mouth and neck of the container body is provided, and a part of the inward flange is cut off, so that the mounting of the liquid spouting plug is more facilitated. Despite being strong, it is not difficult to break the thin wire for breaking.
