Description

TECHNICAL FIELD

[0001] The utility model relates to a container, in particular to a container with a multi-layer bag body to achieve easy tearing effect. BACKGROUND

[0002] In order to meet the needs of consumers to carry and quickly eat, manufacturers put various foods into film packaging bags. Such packaging bags often use the superimposed structure of polyethylene film and aluminum film to achieve waterproof and airtight effect to avoid the deterioration of the contents. When consumers need to eat the contents, they tear open the packaging bag to eat. However, polyethylene film does not break neatly due to its material properties, and often stretches a certain distance before breaking, leaving a gap with some stretched polyethylene film, causing inconvenience to consumers.

[0003] Therefore, based on years of research and practical experience in the relevant field, the present inventors have invented a container to improve the shortcomings of the prior art. SUMMARY

[0004] The main purpose of the utility model is to provide a container that breaks neatly when a consumer applies force to tear it open.

[0005] To achieve the above purpose, the container of the utility model includes a bag body formed by overlapping and heat-pressing the two ends of a sheet body. The sheet body includes, from the outside to the inside, a polyethylene outer film (PE), a polyethylene terephthalate film (PET), an aluminum film, a nylon film (Nylon), and a polyethylene inner film (PE). The bag body can contain a food gel, and the consumer can quickly eat after tearing open the utility model. If printing is needed, it can be printed on the polyethylene terephthalate film, with the polyethylene outer film protecting the printing.

[0006] In one embodiment, one end of the bag body is provided with a retracted tear-off portion, which can be smaller in size than the bag body, so that when the consumer applies force, the utility model can break from the retracted tear-off portion. The opposite sides of the retracted tear-off portion can be symmetrical in shape, so that the consumer can achieve the same tearing effect no matter which side they apply force to, increasing the convenience of the consumer in tearing open the packaging.

[0007] In one embodiment, the overlapping portions of the two ends of the sheet body are completely heat-pressed, so that the outer side of the utility model is flat without raised edges.

[0008] The polyethylene outer film is adhered to the polyethylene terephthalate film, and the polyethylene inner film is adhered to the nylon film, so that when the user tears the utility model, the polyethylene outer film can be torn along the fracture of the polyethylene terephthalate film, and the polyethylene inner film can be torn along the fracture of the nylon film, thereby avoiding the problem that the polyethylene film of the existing bag body is not easy to tear neatly. Moreover, the polyethylene terephthalate film is harder than the polyethylene outer film, and the nylon film is more flexible than the polyethylene inner film, so that the strength of the utility model can be increased, and the opportunity of being broken under pressure can be reduced. The polyethylene inner film can also be made of polyethylene material which is easy to tear.

[0009] In order to clearly and fully disclose the utility model, and to list the preferred embodiment of the drawing, the implementation mode will be described in detail as follows. BRIEF DESCRIPTION OF DRAWINGS

[0024] Please refer to Figure 1 and Figure 2, the drawings of the embodiments of the present invention are disclosed. The above drawings illustrate the container of the present invention, which includes a bag body 1, which is formed by overlapping the two ends of a sheet 11 and then hot-pressing and bonding them. The sheet 11 includes a polyethylene outer film 111, a polyethylene terephthalate film 112, an aluminum film 113, a nylon film 114 and a polyethylene inner film 115 from the outside to the inside.

[0025] In the first embodiment, one end of the bag body 1 is provided with an inwardly retracted tearing portion 12 ( Figure 1 Below, at the front end of Example 1, the indented tear portion 12 can be smaller than the bag body 1, allowing the bag body 1 to be opened by the consumer applying force from the front end. In Example 1, the front end of the bag body 1 also has heat-embossed embossed patterns to facilitate gripping and tearing. The rear end of the bag body 1 also has heat-embossed embossed patterns. The opposing sides of the indented tear portion 12 can be symmetrical, tapering inward on both sides. This allows the consumer to achieve the same tearing effect regardless of which side they apply force from, increasing the convenience of tearing the package. If printing is desired, the present invention can be printed on the polyethylene terephthalate film 112, with the polyethylene outer film 111 protecting the printing.

[0026] Figure 2 As can be seen in the figure, when the bag body 1 of the first embodiment is formed by hot pressing, the overlapping parts of the two ends of the sheet body 11 are completely hot pressed and bonded, and the edge of the outward end of the sheet body 11 will not be warped ( Figure 2 The outer side of the lower middle part faces the left edge), so that the outer side of the utility model is flat, and the edge of the sheet 11 is not easy to rub against other objects to cause inconvenience.

[0027] The utility model laminates the polyethylene outer film 111 with the polyethylene terephthalate film 112 and the polyethylene inner film 115 with the nylon film 114, so that the user can Figure 3 When the present invention is torn, the outer polyethylene film 111 can be severed along the fracture of the polyethylene terephthalate film 112, while the inner polyethylene film 115 can be severed along the fracture of the nylon film 114, thus avoiding the problem of the polyethylene film of the conventional bag 1 being difficult to tear cleanly. The bag 1 can contain a food gel 2, which the consumer can quickly consume after tearing the bag open to replenish energy.

[0028] The polyethylene terephthalate film 112 is harder than the polyethylene outer film 111, and the nylon film 114 is tougher than the polyethylene inner film 115, thereby increasing the strength of the present invention and reducing the chance of rupture under pressure. The polyethylene inner film 115 can also be made of easy-to-tear polyethylene material, making the present invention easier to tear without residue.

[0029] The above is only the preferred embodiment of the present application, and cannot be used to limit the scope of the present application. Any changes and modifications obvious to those skilled in the art shall be considered as not departing from the essential content of the present application.
