Abstract

According to the present invention, in order to be able to easily follow a liquid material such as a liquid or a fat packaged in a synthetic resin bag, the inner adhesive part (05) is hot pressed on the synthetic resin bag to form a discharge passage (06) to form a solid container (04). The contents of the liquid (02) or the like can be easily poured into the inlet and outlet of the container.

An inner passage part 05 is adhered by hot pressing to an upper portion or one side portion of a bag composed of two or two layers of synthetic resin films for packing a liquid substance such as liquid (02) or oil or fat and discharge outlet (06). Form.

At this time, the width of the inner adhesive portion 05 can be adjusted according to the viscosity and safety of the contents of the liquid 02 or the like packaged in the synthetic resin bag. (FIGS. 3 and 8).

In order to facilitate the movement of the discharge passage 06 of the synthetic resin bag, the cut line 07 or the dashed line cut line 08 is cut or drilled based on the virtual center line of the inner adhesive portion 05.

Further, in order to facilitate the cutting of the upper portion of the incision line 07 or the dotted line incision line 08, a? -Shaped cut mark may be punctured, and a V-shaped cut mark may be cut or punctured in the upper portion of the envelope. (Fig. 5, Fig. 6)

A-shaped air inlet adhesive portion 09 is compressed at high temperature and on one side of the synthetic resin bag to form an air inflow passage 10, which facilitates the inflow of air and easily follows the contents of the liquid (02) or the like. (FIG. 7)

By the above method, the contents of the liquid (02) or the like packaged in the synthetic resin bag can be easily followed.

Even when the remaining amount is left, the discharge passage 06 is knotted or knotted, or the discharge passage 06 is folded and then adhesive tape is stored to keep the airtight.

Description

Synthetic resin bag for packing liquid

The present invention relates to a synthetic resin bag for forming a discharge passage 06 by hot pressing the inner adhesive portion (05) to the synthetic resin bag in order to be able to easily follow the liquid material such as liquid or oils packed in the synthetic resin bag.

In general, liquid materials such as liquid 02 or oils and fats have been stored and used in solid containers 04 such as glass, metal, plastics and the like.

In consideration of the efficiency of packaging and environmental aspects, two envelopes are compressed at high temperature, or two layers of synthetic film folded at the bottom in a W-shape to form a bag that is hot pressed at the top and sides. 02) or the liquid material was packaged to be moved and stored (Fig. 1).

2;

In general, the upper portion of the side of the synthetic resin bag is cut by using scissors or the like diagonally to transfer the contents of the liquid (02) and the like to the solid container (04).

At this time, the process of transferring to the container 04 requires careful attention.

In addition, if the remaining amount of liquid remains in the plastic bag, careful care is also required for storage.

8 is a perspective view of a liquid packaging synthetic resin bag in which an inner adhesive portion is hot-pressed on one side of an envelope to form a discharge passage, a dotted cut line is formed in the inner adhesive portion, and an air inlet passage is formed by hot pressing the air inlet adhesive portion.

The present invention to solve the above problems;

3;

An inner passage part 05 is adhered by hot pressing to an upper portion of an envelope composed of two or two layers of synthetic resin films for packaging a liquid substance such as a liquid 02 or a fat or oil, thereby forming a discharge passage 06.

At this time, the inner adhesive portion 05 has a length of 1/2 or more and 3/4 or less of the width of the envelope, at one side of a position that is 1/10 or less 1/5 or more of the height of the envelope, and width is 2 times or less than the adhesive portion 01 Shall be.

At this time, the width of the inner adhesive portion 05 can be adjusted according to the viscosity and safety of the contents of the liquid 02 or the like packaged in the synthetic resin bag.

When the width of the inner adhesive portion (05) is wide, since the inflow of air is blocked when following the contents in the synthetic resin bag, the contents will follow only when pressure is applied to the bag.

4;

It cuts along the imaginary center line of the inner adhesive part 05 of an envelope, cut | disconnects the cutting line 03 which rises perpendicularly from the inner adhesive part 05, and discharges the 06 into the inlet and outlet of the solid container 04. To easily pour contents such as liquid (02).

5;

In order to facilitate the movement of the discharge passage 06 of the synthetic resin bag, the cut line 07 is cut or drilled based on the virtual center line of the inner adhesive part 05.

At this time, both ends of the incision line 07 is perforated in a circle.

In addition, an adhesive tape may be attached to prevent the synthetic resin bag from tearing along the incision line 07.

6;

The dotted cut line 08 may be cut or perforated in the inner adhesive portion 05 of the synthetic resin bag.

At this time, the cut line 07 or the dashed line cut line 08 may start from one side of the envelope.

Further, in order to facilitate cutting in the upper portion of the incision line 07 or the dotted line incision line 08, a? -Shaped cut mark may be perforated, and a V-shaped cut mark may be perforated on the upper part of the envelope.

7;

When the viscosity of the contents of the liquid 02 or the like of the synthetic resin bag is large;

A-shaped air inlet adhesive portion 09 is compressed at high temperature and on one side of the synthetic resin bag to form an air inflow passage 10, which facilitates the inflow of air and easily follows the contents of the liquid (02) or the like. To help.

8;

The inner adhesive portion 05 is attached to one side portion of the synthetic resin bag by hot pressing to form a discharge passage 06.

At this time, in order to facilitate the movement of the discharge passage 06 of the synthetic resin bag, the incision line 07 or the dotted line incision line 08 is cut or perforated based on the virtual center line of the inner adhesive part 05.

In addition, the air inlet passage 10 is formed by pressing the a-shaped air inlet adhesive part 09 at a high temperature on the upper part and one side of the synthetic resin bag.

If there is remaining charge in the plastic bag; Tie the discharge passage 06 in a knot, or fold the discharge passage 06 and then adhere the adhesive tape to keep it airtight.

The inner adhesive portion 05 is pressed at a high temperature to the synthetic resin bag to form the discharge passage 06, so that the contents such as the liquid 02 can easily be poured into the solid container 04.

In addition, even when the remaining amount is left in the synthetic resin bag, the discharge passage 06 is knotted, or the discharge passage 06 is folded, and then the adhesive tape is adhered and stored to maintain airtightness.
