Description

A strong emptying flexible packaging bag

technical field

The utility model relates to the technical field of flexible packaging, in particular to a strong emptying flexible packaging bag.

Background technique

At present, there are many types of flexible packaging bags for liquid storage and transportation on the market. In order to facilitate the flow of liquid or semi-colloid, or as a food packaging bag for people to suck, there are generally two ways to open the flow tube in the existing flexible packaging bags: ① There is a nozzle with a screw cap at the opening, which can be poured or sucked after unscrewing the cap; ② There is a hidden straw at the opening, which can be poured or sucked after tearing off the heat seal. However, in the above two opening methods, the part where the straw is inserted into the inner cavity of the packaging bag will form a groove with the surrounding heat sealing line. When the packaging bag is tilted or turned upside down, although the liquid or semi-colloid can flow out or be sucked smoothly, but There is still some liquid or semi-colloid remaining in the grooves on both sides of the flow tube, causing waste.

Contents of the invention

The purpose of the utility model is to provide a strongly emptied flexible packaging bag in view of the existing technical status, which forcibly empties the liquid or semi-colloid in the inner cavity of the bag through a porous flow tube, avoids waste, and is hygienic and environmentally friendly.

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model relates to a strong emptying flexible packaging bag, which mainly includes a sealed bag body, a flow tube is arranged at one corner of the inner cavity of the bag body, and a tear line is formed on one corner of the bag body after laser treatment, and the tear line is diagonally across In the middle part of the flow tube, several through holes are opened on the tube wall of the lower part of the flow tube.

In the above solution, the outer contour of the bag covering the upper part of the flow tube is heat-sealed to form a heat-sealing line.

Further, the two ends of the heat-sealing line extend to the two adjacent sides of the bag body to form a tearable opening.

Further, the tear line obliquely crosses the heat-sealing line on both sides of the flow tube.

In the above solution, a tear opening is provided on the top of the bag body, and one end of the tear line extends to the upper side of the bag body to fit with the tear opening, so as to facilitate the tearing of the bag mouth.

The beneficial effects of the utility model are:

1. Hidden nozzle, clean and hygienic;

2. It can be opened as soon as it is torn, and the liquid is not easy to seep out from the nozzle when it is torn;

3. When pouring or sucking, it can be squeezed towards the mouth of the tube to empty the liquid in the bag to avoid waste or part of the liquid remaining to breed bacteria.

detailed description:

In order to enable the review committee to have a further understanding of the purpose, features and functions of the present utility model, the preferred embodiments are hereby given in detail with the accompanying drawings as follows:

Please refer to Fig. 1, which is a structural schematic diagram of a preferred embodiment of the present utility model. The utility model is a strong emptying flexible packaging bag, which mainly includes a sealed bag body 1, and a corner of the inner cavity of the bag body 1 is provided. There is a flow tube 2, and a corner of the bag body 1 has a tear line 3 after laser treatment, and the tear line 3 obliquely crosses the middle of the flow tube 2, that is, the upper part of the flow tube 2 is in the range of tearing, and the lower part of the flow tube 2 Part of it is within the scope of the inner cavity of the bag body 1 . Wherein, the tube wall of the lower part of the flow tube 2 is provided with a plurality of through holes 21, and the liquid or semi-colloid in the bag body 1 can be discharged smoothly from the through holes 21, so as to avoid remaining in the groove formed around the flow tube 2; The body 1 covers the outer contour of the upper part of the flow tube 2 and is heat-sealed to form a heat-sealing line 4. The two ends of the heat-sealing line 4 extend to the two adjacent sides of the bag body 1, and the tear line 3 obliquely crosses the heat on both sides of the flow tube 2. The sealing line 4, wherein, tearing along the tearing line 3 also divides the involved heat sealing line 4 into two parts, and the heat sealing state near the mouth of the flow tube 2 remains intact after tearing.

In the above scheme, a tear opening 5 is provided above the bag body 1, and one end of the tear line 3 extends to the top of the bag body 1 to fit with the tear opening 5, that is, an opening can be torn out along the tear line 3 through the tear opening 5 .

Of course, the above illustrations are only the preferred implementation modes of the utility model, and are not intended to limit the scope of application of the utility model. Therefore, any equivalent changes made on the principle of the utility model should be included in the protection scope of the utility model .
