Description

Technical Field

[0001] The invention relates to a gasket, in particular to an easy-to-tear gasket. Background Art

[0002] In the prior art, a gasket is generally welded to the bottle mouth. When the liquid in the bottle needs to be used, the gasket needs to be torn off. Conventional gaskets are made of aluminum foil, which is relatively strong and difficult to tear off, making the liquid in the bottle difficult to use. Summary of the Invention

[0003] To solve the above technical problems, the present invention aims to provide a gasket that is easy to tear and can be inserted into a pipe. The technical solution of the present invention is as follows:

[0004] An easy-to-tear gasket, characterized by comprising a pull ring (3), an aluminum foil (1), and a film (2) connected in sequence.

[0005] The aluminum foil sheet (1) is provided with a through hole (14), an inner ring portion (13), and an outer ring portion (11) in sequence from the inside to the outside, wherein the inner ring portion (13) and the outer ring portion (11) are connected via a plurality of spaced connection portions (12);

[0006] The pull ring (3) and the inner ring portion (13) are connected by welding via a welding ring (31);

[0007] The film (2) is welded to the aluminum foil (1), and the film (2) is connected to the outer ring portion (11) by heat-melting through a first heat-melting ring (21), and is connected to the inner ring portion (13) by a second heat-melting ring (22);

[0008] After the pull ring (3) is pulled, the pull ring (3) pulls the inner ring portion (13) through the welding ring (31) to drive part of the connecting portion (12) to be disconnected, and at the same time, the inner ring portion (13) drives the film (2) to be torn along the outer portion of the first hot melt ring (21), so that a material removal port (4) is formed in the middle of the film (2).

[0009] Furthermore, the connecting parts (12) are arranged in an array along the center of the inner ring part (13). Furthermore, the number of the connecting parts (12) is 2-12.

[0010] Furthermore, the pull ring (3) is in the shape of a ring and is made of aluminum foil.

[0011] Furthermore, the connecting portion (12) is formed by cutting a notch (15) on the aluminum foil (1). Furthermore, the gasket is prepared by:

[0012] S1, cutting a circular through hole (14) in the middle of the aluminum foil (1), cutting a plurality of cuts (15) on the aluminum foil (1) to form a connecting portion (12), and forming an inner ring portion (13) and an outer ring portion (11) inside and outside the connecting portion (12);

[0013] S2, ultrasonically welding the lower portion of the aluminum foil (1) and the thin film (2);

[0014] S3, hot-melt the inner ring portion (13) on the film (2) to form a second hot-melt ring (22), and align it with the outer ring portion (13)

[0015] After hot melting, a first hot melting ring (21) is formed;

[0016] S4, welding the pull ring (3) and the inner ring portion (13) on the upper portion of the aluminum foil (1) to form a circular welding ring (31). By means of the above solution, the present invention has at least the following advantages:

[0017] The gasket of the invention can be conveniently used to tear open the plastic film at the bottom through a pull ring, and then a tube can be inserted into the tube to use the liquid in the bottle.

[0018] After the gasket of the present invention is torn open, the material taking-out opening is smaller than the bottle opening, and the inserted tube can be fixed.

[0019] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings.

[0034] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0035] 1 to 9 , an easily tearable gasket according to a preferred embodiment of the present invention comprises a pull ring 3 , an aluminum foil 1 , and a film 2 connected in sequence.

[0036] The aluminum foil 1 is provided with a through hole 14, an inner ring portion 13, and an outer ring portion 11 in sequence from the inside to the outside, wherein the inner ring portion 13

[0037] The outer ring portion 11 is connected to the outer ring portion 11 through a plurality of spaced connection portions 12. The aluminum foil sheet 1 is formed by cutting and notching the circular aluminum foil.

[0038] The connecting portion 12 is arranged along the center of the inner ring portion 13 in an array. The number of the connecting portions 12 is 2-12 and can be adjusted according to the actual situation.

[0039] The specific setting is made according to the actual needs. When there are two connecting parts 12, only one of them will be broken.

[0040] 12 is formed by cutting slits 15 on the aluminum foil 1, and all the slits are on the same circle.

[0041] The pull ring 3 and the inner ring portion 13 are connected by welding through a welding ring 31. The pull ring 3 is annular and made of aluminum foil. Generally, only one welding ring 31 is set, and the welding ring 31 is circular. Multiple welding rings 31 can also be set, but the welding rings 31 must be close to each other.

[0042] The film 2 is welded to the aluminum foil 1 by an ultrasonic welding machine, and the film 2 is welded to the aluminum foil 1 by a first hot melt

[0043] The outer ring portion 11 is connected to the outer ring portion 11 by heat melting, and the inner ring portion 13 is connected to the inner ring portion 13 by the second heat melting ring 22.

[0044] The two heat-melting rings 22 are formed by contacting and heating the annular heating ring.

[0045] After the pull ring 3 is pulled, the pull ring 3 pulls the inner ring portion 13 through the welding ring 31 to drive part of the connecting portion 12 to break.

[0046] At the same time, the inner ring portion 13 drives the film 2 to tear along the outer portion of the first hot melt ring 21 so that the film 2

[0047] The middle portion forms a material outlet 4. The first heat-melting ring 21 makes the connection more secure and can be torn off. The second heat-melting ring 22 plays a role in better fixing the connection.

[0048] When in use, the entire gasket is welded to the bottle mouth. After being torn open, a tube can be inserted through the material taking port 4 to use the liquid inside the bottle.

[0049] The preparation method of the gasket is as follows:

[0050] S1, cutting a circular through hole 14 from the middle of the aluminum foil 1, and cutting a plurality of cuts 15 on the aluminum foil 1 to form connecting portions;

[0051] 12, and forming an inner ring portion 13 and an outer ring portion 11 inside and outside the connecting portion 12;

[0052] S2, connecting the lower portion of the aluminum foil 1 and the film 2 by ultrasonic welding;

[0053] S3, hot-melting the inner ring portion 13 on the film 2 to form a second hot-melt ring 22, and hot-melting the outer ring portion 13 to form a first hot-melt ring 21;

[0054] S4. Weld the pull ring 3 and the inner ring portion 13 on the upper portion of the aluminum foil 1 to form a circular welding ring 31. The present invention has at least the following advantages:

[0055] The gasket of the invention can be conveniently used to tear open the plastic film at the bottom through a pull ring, and then a tube can be inserted into the tube to use the liquid in the bottle.

[0056] After the gasket of the present invention is torn open, the material taking-out opening is smaller than the bottle opening, and the inserted tube can be fixed.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
