Description

[Detailed explanation of the idea] (Industrial application field) This proposal relates to a dispensing tool for packaging containers.

(Prior Art) Conventionally, as seen in Japanese Unexamined Patent Publication No. 57-6746, the spout of a container body coated with polyethylene is covered with a thin lid paper coated with polyethylene.

In addition, an annular thin-walled part that is cut into the lid to form a spout is provided, and a tension protrusion is provided in the area surrounded by this thin-walled part.
It is shown in the publication No.

(Problems to be solved by the invention) With the above-mentioned Japanese Patent Application Laid-open No. 57-6746, opening the pouring spout is complicated, and the thin paper falls into the container, which is unhygienic. It is true. Moreover, in the case of the one disclosed in Japanese Utility Model Application Publication No. 59-72273, when you put your finger on the tensile protrusion and pull it, the thin part at the bottom of the groove of the annular thin part breaks along this, forming a spout. However, since the multilayer film bonded to the back surface of the lid is bonded to the entire surface of the lid, it cannot be easily cut, making it difficult to form a spout.

(Means for solving the problem) Therefore, the purpose of the present invention is to provide a dispensing tool for a packaging container whose spout can be easily opened. is a dispensing tool that is welded onto a laminate layer stretched over the opening of the packaging material, and has a funnel-shaped notch in the lid, and a pull ring extending from the funnel outlet.
A notch is provided at the joint of the pull ring at the funnel outlet to form the needle tip when the pull ring is pulled up, and a thin section is provided across the funnel inlet, and both sides of the funnel formed by the notch are locked. This is a dispensing tool for a packaging container, which is provided with bifurcated parts at both corners of the lid that are narrower than a funnel-shaped cut.

(Effect of the invention) According to this technical means, when the pull ring is pulled up, a needle tip is formed by the cut at the joint part of the pull ring, which bites into the inside of the laminate layer, and the laminate layer at the opening of the packaging material. When the pull ring is pulled up further, the laminate layer at the opening welded to the lid will be peeled off by tightening the bit.

Then, the lifted lid is torn into a funnel shape by the cut. Both sides of the funnel of the torn lid are locked at the forked parts, so even if the container is tilted, the lid will not move and cover the opening. With conventional systems where the lid is simply welded to the laminate layer at the opening, when the lid is removed, the laminate layers separate, but with the proposed method, the laminate layer at the opening is partially broken when the pull ring is pulled up. This tightening makes opening easier.

However, compared to the conventional lid in which a multilayer film is bonded over the entire back surface, the lid can be opened more easily.

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

1 is a packaging material in which an opening 2 is made, which is sealed with a laminate layer 3. Opening 2
The shape is bullet-shaped, and the lid 4 of the dispensing tool is welded to the laminate layer 3.

Also, the thickness 4 has the same shape as the opening 2.
a is formed on the lid member 4. The lid member 4 has a funnel-shaped notch 5, and a pull ring 6 extends from the funnel outlet. There is a nail tip type notch 7 at the joint between the pull ring 6 and the funnel type notch.

Furthermore, there is also a thin wall section 8 at the cross section of the funnel inlet.

There are bifurcated parts 9, 9 at both corners of the lid 4, which are slightly narrower than both sides of the funnel-shaped notch 5 so that both sides of the lid 1 cut into a funnel shape can be locked.

The pull ring 6 is bent at a right angle and attached to a corner of the packaging material.

The main case structured as above is the 6th,
A pouring tool shown in FIGS. 7 and 8 is welded to the laminate layer 3 of the opening 2 and attached to the container as shown in FIG. When opening the opening, as shown in FIG. 3, when the pull ring 6 is pulled up, the tip of the nail tip 10 formed in the notch 7 of the joining part bites inward to tear the laminate layer 3 and create a tight opening.

When the pull ring 6 is further pulled up, the laminate layer 3 welded to the thick portion 4a of the lid body 4 is peeled off at the bited part to open it.

Next, the two forks 9, 9 on the opposite side are narrower than the notches 5, 5 on both sides of the torn funnel, so by pressing the torn lid 11 on these, the funnel-shaped lid 11 will fit into this. It is locked, so that even if the container is tilted, the opening will not be covered, and the lid will not be soiled by the contents.
