Description

Technical Field

[0001] The utility model specifically relates to a special-shaped double-chamber bag capable of extruding mixed liquids. Background Art

[0002] Packaging bags are mainly used to pack various items to facilitate transportation.

[0003] Magic glue is a colloid made by mixing A / B component glues. It is generally used as a children's toy and has the characteristic of being able to be molded. Due to the characteristics of magic glue, the two components A / B need to be stored separately. When using, the A / B components need to be mixed and kneaded before they can be molded and used. The existing packaging method is that the A / B components are separately packed in independent plastic boxes, and then poured out and mixed when they are used. This packaging method has the following disadvantages: 1. It is not easy to operate, and the two components need to be poured out and mixed. 2. The cost is high, and the cost of plastic hard packaging boxes is relatively high. 3. There is a lot of waste, and the two components cannot be poured out cleanly, resulting in residual waste. Based on the above shortcomings, it is urgent to launch a double-chamber bag. Utility Model Content

[0019] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0020] Embodiment 1: Figure 1~2 As shown, a special-shaped double-chamber bag for extruding mixed liquids includes a bag body 1 made of an annular composite film, both sides of the annular composite film are formed by heat-pressing and sealing, and the bag body has a bottle-like shape.

[0021] The annular composite film includes an inner layer 2 , a middle layer 3 and an outer layer 4 in order from the inside to the outside, and an ink layer 5 is provided between the middle layer 3 and the outer layer 4 .

[0022] In this embodiment, the inner layer 2 is an easy-to-tear CPP film layer, the middle layer 3 is a BOPA film layer, and the outer layer 4 is a PET film layer. The inner layer 2 is an easy-to-tear CPP film layer, which meets the characteristics of low sealing temperature, medium resistance, easy to peel, and high temperature non-dead sealing.

[0023] The inner layer 2 and the middle layer 3 are bonded together by an adhesive 6 , and the middle layer 3 and the outer layer 4 are bonded together by an adhesive as well.

[0024] The bag body 1 includes a first cavity 7 and a second cavity 8, which are separated by a heat seal strip 9. An easy-tear seal 10 is provided in the middle of the heat seal strip 9, and the width of both sides of the heat seal strip 9 gradually decreases to the easy-tear seal 10.

[0025] During heat sealing, the heat sealing strength of the tearable seal 10 is controlled between 1.5 and 2.5 N, and the heat sealing strength of the heat sealing strips on both sides of the tearable seal 10 is controlled above 15 N, so that the middle seal can be opened when in use, and the contents will not leak when not in use or during transportation.

[0026] In this embodiment, the easy-tear seal 10 is arranged in a wave line. The two sides of the heat seal strip are in a descending wedge shape, and the middle is in a wave shape. This design makes the force point more concentrated on the wave during extrusion, making it easier to break the middle seal.

[0027] In this embodiment, the first cavity 7 is located above the second cavity 8, which makes it easier for the glue in the upper cavity to enter the lower cavity for mixing.

[0028] Of course, the products to which this application is applicable are not limited to magic glue, but can also be used for products that require mixing, such as facial masks and essences.

[0029] In this embodiment, a serrated tear 11 is provided on the top side edge of the bag body 1 .

[0030] Embodiment 2: Figure 3 As shown, as another embodiment, the top of the bag body 1 is provided with a crescent-shaped arc opening 12. This can enhance the display of the bag body 1 on the shelf, better attract consumers' attention, and increase product sales.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equalization change and modification made to the above embodiment by any technician familiar with the field without departing from the content of the technical solution of the present invention based on the technical essence of the present invention shall fall within the scope of the present invention.
