Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a spout stopper for a liquid container containing juice, alcoholic beverages, etc.

[Conventional technology]

BACKGROUND ART Conventionally, in consideration of manufacturing costs and ease of handling, many Goebelt-top and flat-top liquid paper containers, which are mainly made of paper, have been on the market. Along with this, many improvements have been made to the structure of the pouring stopper through which the contents are poured out, including making it easier to open. As one example, as shown in FIG. 4, in a flat-top type liquid container, a spout B located on the top surface of the container body A has a sheet-like mounting member b provided with a through hole a, and a sheet-like mounting member b provided with a through hole a; Some devices are equipped with a spout d consisting of a lid member c and a lid member c that covers the lid, and by peeling off the lid member c until the through hole a is exposed, the spout is opened and the contents can be poured out. It was becoming like that.

[Problem that the invention attempts to solve]

However, in the above-mentioned conventional spout tap, as described above, the spout tap is provided as two separate members, and when the lid member is strongly pulled up, the lid member is completely separated from the mounting member. There was a problem in that the two members had to be firmly welded at one end e to prevent them from peeling off, making the process of providing the pouring stopper complicated.

[Means for solving problems]

The present invention was made in consideration of the above-mentioned conventional problems, and includes a mounting member that is provided with a through hole corresponding to the spout of a liquid container and is attached to the peripheral edge of the spout, and a mounting member that is attached to the peripheral edge of the spout. A lid member that can be opened and closed is integrally provided via a folded part, and a flexible piece of the mounting member protrudes outward from the rim of the liquid container located below during pouring, and Provided is a spout stopper for a liquid container, characterized in that the lid member is removably attached to at least one of the mounting member and the liquid container via an adhesive, and the through hole is provided so as to be resealable. This solves the above-mentioned conventional problems.

[Effect]

In the present invention, even if the lid member integrated with the mounting member attached to the container body side is pulled up strongly, the lid member does not separate from the mounting member, and the spout can be resealed with the lid member at any time.

〔Example〕

Next, the present invention will be explained in detail based on an embodiment shown in FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a spouting stopper. As shown in FIG. It is attached. and the spout plug 1
consists of a mounting member 2 having a through hole 20 corresponding to the spout B, and a lid member 4 that covers the through hole 20 and is integrated with the mounting member 2 via a folding portion 3, for example. It is formed by folding a flexible sheet-like material made of metal foil coated with a resin such as polyethylene, and the folded portion 3 is located on the top side of the upper inclined surface.

The mounting member 2 is firmly adhesively fixed to the peripheral edge of the spout so that the through hole 20 and the spout B coincide with each other, and the liquid container is used to pour out the contents from the lower twill portion C of the upper inclined surface. When the liquid container is tilted, a piece 21 of the mounting member 2 pours out outward along the slope of the upper slope from the twill part of the liquid container located below. The container is designed to prevent liquid from dripping so that the contents do not run down the outer surface of the container.

An adhesive 5 is provided on the back surface of the lid member 4 so as to seal the through hole 20, that is, the spout B, corresponding to the peripheral edge of the through hole 20. Further, the tip 40 of the lid member 4 is provided so as to cover a flexible piece 21, and this piece 21 can be bent toward the liquid container and peeled off via the adhesive 6 applied to the back side. It is attached to the liquid container.

To open the spout B, it is sufficient to raise the tip 40 of the lid member 4 from the liquid container and pull the entire lid member upward. In this case, the adhesive 5 is weaker than the adhesive force that adhesively fixes the mounting member 2 to the liquid container, so that the mounting member does not separate from the liquid container when the lid member is pulled up. Furthermore, when resealing the spout B, fold down the lid member 4 and open the tip 40.
The spout B is covered with the lid member 4 and resealed.

In the above embodiment, the adhesive strength between the lid member and the mounting member was made weaker than the adhesive strength between the mounting member and the liquid container so that the lid member could be reliably peeled off. The coating layer made of polyethylene or the like may be made thinner than the attachment member side so that the lid member can be reliably peeled off even if the adhesive strength between the two is the same.

[Effect of idea]

As explained above, according to the present invention, the spout includes a mounting member that is provided with a through hole corresponding to the spout and is attached to the peripheral edge of the spout, and a lid member that covers the through hole so that it can be opened and closed. and are integrally provided via a folding part,
The flexible piece of the mounting member protrudes outward from the twill portion of the liquid container located below during pouring, and the lid member is peeled off to at least one of the mounting member or the liquid container via the adhesive. Since it can be attached and the through hole can be resealed,
Even if the lid member is strongly pulled up when opening the spout, the lid member does not separate from the mounting member, and the spout can be resealed at any time without using a separately molded member, and the lid member and the mounting member are Since it is integrated, it is easy to manufacture the pouring stopper, and the manufacturing cost of the liquid container does not increase, resulting in excellent practical effects.
