[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1-2 , Figure 5 A sealing and easy-open film structure for a packaging can includes a bottle 1, a bottle cap 2 and a composite film body 3, wherein an annular sealing base 4 is fixedly installed on the inner side of the bottle 1 near the top.

[0034] Two sealing rings 5 ​​with different radii are fixedly installed on the upper surface of the annular sealing base 4;

[0035] The composite membrane body 3 is sealed and fixed to the upper surface of the annular sealing base 4 by hot pressing, and the mouth of the bottle 1 is sealed.

[0036] The composite film body 3 is made of transparent or semi-transparent material. The transparent composite film can provide a clear and unobstructed view in any state, allowing consumers to intuitively inspect the state of the contents without opening the can.

[0037] A tear strip 6 is fixedly provided on the composite membrane body 3. One end of the tear strip 6 is a free end 7, and the other end is a fixed end 8.

[0038] The upper surface of the annular sealing base 4 is provided with an adhesive area.

[0039] With reference to Figures 4-5 , specifically: the composite film body 3 is heat-pressed on the annular sealing base 4 and the sealing ring 5 to form two arches with different radii.

[0040] With reference to Figure 4 , specifically: the tear strip 6 is a film piece pre-punched and partially lifted from the composite film body 3, and the free end 7 thereof constitutes a pulling part.

[0041] With reference to Figure 2 , Figure 4 , specifically: the tear strip 6 is an independent strip-shaped label, and the fixed end 8 thereof is adhered and fixed on the adhesive area of the annular sealing base 4 through a heat-pressing process.

[0042] When the consumer needs to open the package, he / she only needs to pinch the free end 7, i.e. the pulling part, of the tear strip 6 with fingers and peel it off from the fixed end 8. As the tear strip 6 is pulled up, the whole transparent composite film body 3 can be completely torn off from the annular sealing base 4, and the opening process is labor-saving and smooth.

[0043] With reference to Figures 1-2 , specifically: the adhesive area of the annular sealing base 4 is composed of a hot-melt material.

[0044] With reference to Figure 6 , specifically: the composite film body 3 is of a multi-layer composite structure, and at least includes an ink-receiving layer 10 and a heat-sealing layer 11, and the ink-receiving layer 10 is provided with a pattern.

[0045] The transparent composite film body 3 is tightly pressed on the upper surface of the annular sealing base 4 through a heat-pressing process. During the heat-pressing process, heat and pressure make the heat-sealing layer 11 on the lower surface of the composite film body 3 melt, so as to be permanently adhered together with the base and the two sealing rings 5 thereon, forming a firm sealing barrier to effectively block external air and moisture and ensure the shelf life of the contents.

[0046] With reference to Figure 2 , specifically: the annular sealing base 4 is fixed to the mouth of the bottle 1 through welding.

[0047] With reference to Figure 2 , specifically: the material of the annular sealing base 4 is plastic, metal or biodegradable material.

[0048] With reference to Figure 4Specifically, the central position region of the composite film body 3 is provided with a plurality of protrusions 12, so as to ensure the rigidity of the film after heat sealing, and the plurality of protrusions 12 increase the strength of the composite film body 3 in the horizontal direction, effectively preventing the film from sagging.

[0049] With reference to Figure 3 Specifically, the inclined material guide wall 13 is arranged below the annular sealing base 4, and the cross section of the inclined material guide wall 13 is triangular, so as to avoid the blocking of the annular sealing base 4 when the object in the bottle 1 is poured out.

[0050] Working principle: the transparent composite film body 3 is tightly pressed on the upper surface of the annular sealing base 4 through a hot pressing process, and in the hot pressing process, heat and pressure make the heat sealing layer 11 on the lower surface of the composite film body 3 melt, so as to be permanently bonded with the base and the two sealing rings 5 thereon, forming a firm sealing barrier, effectively blocking external air and moisture, ensuring the shelf life of the content, and the transparent composite film can provide a clear and unobstructed view in any state, allowing consumers to intuitively inspect the state of the content without opening the can.

[0051] When the consumer needs to open the package, only the free end 7, i.e. the pulling part, of the tear strip 6 is pinched with the fingers and is peeled off from the fixed end 8, and as the tear strip 6 is pulled up, the whole piece of transparent composite film body 3 can be completely torn off from the annular sealing base 4, and the opening process is labor-saving and smooth.

[0052] In order to ensure the rigidity of the film after heat sealing, the plurality of protrusions 12 increase the strength of the composite film body 3 in the horizontal direction, effectively preventing the film from sagging.

[0053] Since the annular sealing base 4 is arranged in the bottle 1, and the inclined material guide wall 13 is arranged, the object in the bottle 1 can be prevented from being blocked by the annular sealing base 4 when being poured out.

[0054] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
