Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to paper containers for milk, juice, etc., and particularly to a Goebelt push seal type paper container with a pouring spout.

(Prior art) When pouring out the contents of this type of conventional Gebelt push seal-shaped paper container, the Gebelt push seal, that is, the roof-shaped part, is pushed open from the side, and the adhesive part at the top is removed. The spout is peeled off to open and pour out, and is used when filling with sake, soy sauce, etc., but the spout installed on the slope of the roof shape has no connection between the spout itself and the cap. It is formed from two pieces, and in order to pour out the contents,
The cap was removed and the seal inside the spout body was torn off.

(Problems to be solved by the invention) In the former case of the above-mentioned conventional methods, considerable force is required to peel off the adhesive part, and
This is not hygienic because fingers touch the spout opening, and the latter is formed from two pieces, the spout body and the cap.
Considering the cost of the mold, not only did the cost increase accordingly, but it also took time to assemble.

This invention was devised as a result of various studies on these points, and its purpose is to:
In this type of Gebert-Zupschiel type container,
By simplifying the configuration of the spout, we aim to reduce costs, make it easier to open the spout and make it sanitary, and maintain the stability of the hinged lid when pouring out the contents, so that the The purpose is to prevent foreign matter such as dust from entering by simply closing the lid.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a pouring spout having a hinged lid with a locking knob is mounted on the inclined surface of a Goebeltsipseal paper container. By doing so, we are trying to solve problems.

That is, the present invention provides a Gebert top seal type paper container, and the spout body attached to the inclined surface of the container body has a hinge portion on the top seal side of the container body, and the spout body A hinged lid for closing the top seal is provided, and a locking knob is provided on the upper surface of the hinged lid on the opposite side of the hinge to lock the top seal.

(Function) When pouring out the liquid filled and sealed inside the paper container, the Gebelt push seal paper container of the present invention can be opened by separating it from the thin wall part by pulling the locking knob on the hinge lid. The hinged lid, which has now become an opening, is poured while being locked to the top seal portion using the locking knob, and when dispensing is finished, the locking knob is removed and the lid is closed.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In the Goebelt push seal paper container of the present invention, the spout main body A of the spout attached thereto is a one-piece injection molded plastic such as polyethylene or polypropylene; The inner side of the brim-shaped peripheral edge part a to be welded to the inside of the opening of the inclined surface part e of the container body B is the part that should become the hinge lid b, and the peripheral wall 3 of this part b is located on the right side when viewed from the state in FIG. The bulge 1 is formed into a rectangular chevron-shaped bulge 1 that is offset to the side, and when viewed from above (Fig. 2), the bulge 1 has a home-base-shaped tapered shape with a rounded top 2 side. On the home side, the side opposite this is a straight line 4
It shows.

A locking knob c having a hook 5 facing the linear portion 4 is provided near the top 2 of the mountain-shaped bulge 1. The locking tab c may be of any shape as long as it can be gripped and can be locked to the top seal portion of the paper container, which will be described later, after the lid is opened. In addition, a V-shaped groove 6 is recessed in the lower surface of the straight part 4 side, and a locking knob c is inserted from both ends of the V-shaped groove 6 through the outer base of the locking knob c to be cut off during dispensing. A thin walled portion 7 is recessed from the lower surface. Further, the outer lower part of the locking knob c and the inclined surface 8 of the peripheral wall 3 of the mountain-shaped bulge 1
are provided with downward locking protrusions 9 and 10.

In order to attach the spout main body A having such a configuration to the container main body B of the Goebelt-Pseal paper container,
When assembling and forming the paper container main body B, the chevron-shaped bulge 1 is made to protrude outward from the inside at the opening 11 of the inclined surface part e, and the locking protrusion 10 is inserted into the opening 1.
At the same time, the brim-like peripheral edge a is welded to the inner edge of the opening 11 by heating or ultrasonic waves.

When the container body B of the Gebert-Tup seal paper container equipped with the spout body A is filled and sealed with a liquid content such as milk or juice, when the liquid content is to be poured out, it is necessary to Stop knob c
When it is pinched and pulled, the force is concentrated on the thin walled part 7 of the base via the locking knob c, so a break occurs from this part, and the break spreads to the surface side, causing the V-shaped groove 6 to break. It stops and opens after passing both ends. This broken mountain-shaped bulge 1 becomes the hinge lid b, which is bent from the V-shaped groove 6, so attach the locking knob c to the top seal portion 12 of the container body B of the Goebelt top seal paper container. to lock. After this state is reached, the container body B is tilted and the liquid content is poured out from the opened protruding spouting part.

After pouring, insert the locking knob c into the top seal part 12.
Then, return the hinged lid b to the spout and close the lid. At this time, the locking protrusion 9 on the outer lower part of the locking knob c locks on the lip of the spout, preventing the hinge lid b from falling inward, and preventing the thin wall portion 7 from falling inward.
The hinge lid b will not spring up and open due to burrs caused by cutting.

Next, a spout main body A' used in a container main body B' of a Goebelt push seal type paper container according to another embodiment shown in FIGS. 6 to 8 will be described.

This spout body A' is different from spout body A,
It is welded to the outside of the opening 11' of the container body B' of a Goebelt push seal type paper container, and is formed into a one-piece flat home base shape 3' by injection molding of plastic. The lower surface of the spout body A' has an opening 1 of the container body B'.
1' and a home base-shaped protrusion that mates with
b", and the lower surface of its outer periphery is a collar-shaped adhesive part a'. At the center position of the protruding part b" on the home side, a hook 5' is attached to the upper surface of the spout body A'. A locking knob c' provided therein protrudes, and a V-shaped groove 6' is provided from the lower surface of the collar-shaped adhesive part a' of the linear part 4' on the side opposite to the platform side. .

The shape of the hook 5' is not critical as long as it can be engaged with the top seal portion 12'. To attach the spout main body A′ as described above to the container main body B′ of a Goebelt-Pseal paper container, insert the protrusion b″ on the lower surface of the spout main body A′ onto the inclined surface e′ of the container main body B′. It fits into the opening 11', and the flange-like adhesive part a' on the periphery thereof is welded.

A container body equipped with such a spout body A′
When pouring out the liquid from B' filled with milk, juice, etc. as the liquid content and sealed, when you pinch and pull the locking knob c', the force is It is concentrated at the base of c′, and the brim-like adhesive part of this part
When a' begins to peel off, it progresses to both sides and reaches the V-shaped groove 6', where it is bent.

This bent hinged lid b' locks onto the top seal portion 12' of the container body B' with the locking knob c' on its top surface, and in this state, tilt the container body B'. Pour out the contents. After dispensing, when closing the hinged lid b', remove the locking knob c' from the top seal part 12' of the paper container, and insert the bottom protrusion b'' of the hinged lid b' into the opening of the container body B'. 11'.The hinge lid b' remains in its original stable position due to the peeled-off collar-like adhesive part a', and the protruding part b' and the opening 1
It will not spring open with a fitting friction of 1'.

(Effects of the invention) The Gebert-tup seal paper container for milk, juice, etc. of the present invention has a simple structure for the pouring spout attached to it, so it is inexpensive and easy to open. The lid can be easily opened by pulling the locking knob, and in this case, the part that should become the spout is not touched by any fingers, so it is hygienic. When the lid is opened, the locking knob can be locked to the top seal of the container body of the paper container, so when pouring, the hinged lid maintains its position and does not interfere with pouring. After pouring, the lid can be easily closed by simply removing the locking knob and returning the hinged lid to its original position.

This type of paper container for liquid contents has a short period of use after the lid is opened, and is used up relatively quickly.The hinged lid is opened and closed infrequently, and is in a sealed state when the lid is closed. Since it is not necessary, the spout used for such paper containers has a simple and inexpensive structure, and the attached paper container is
It is easy to use, hygienic and truly appropriate.

In addition, in cases where the pouring spout is attached from the outside of the paper container, the opening of the paper container that serves as the pouring spout exposes the cut surface of the paper container body. There is no effect when pouring out the contents of liquids such as , juice, etc. Furthermore, if the spout is attached from the inside of the paper container, it can be used for highly permeable substances such as sake and soy sauce.
