Description
Technical Field
The utility model relates to a seal the gasket field, especially indicate a prevent gluing once more and seal type electromagnetic induction and seal gasket.
Background
The bottle openings of containers for many products (medical drugs, chemicals and foods) need to be sealed by sealing gaskets, so that the contents in the containers are prevented from being polluted by foreign substances, or harmful contents in the containers are prevented from leaking to cause harm and loss.
After a user opens a bottle opening, the electromagnetic induction sealing gasket is basically and completely separated from the bottle opening of a container, so that the bottle opening of the container is clean and has no difference from the bottle opening which is not used; therefore, a lawbreaker can open the container bottle mouth and replace the content in the container and then use the electromagnetic induction sealing gasket again to seal the container bottle mouth, and a conventional user cannot judge that the container bottle mouth is sealed by the electromagnetic induction sealing gasket again, so that the conventional user is easy to cheat.
Therefore, the invention improves the electromagnetic induction sealing gasket, and particularly develops the anti-secondary-sticking type electromagnetic induction sealing gasket.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent gluing once more and seal type electromagnetic induction and seal gasket to overcome not enough among the prior art.
In order to achieve the above purpose, the solution of the present invention is:
an anti-secondary sticking and sealing type electromagnetic induction sealing gasket comprises a sticking and sealing layer, an anti-secondary sticking and sealing layer, an electromagnetic induction heating layer and a back lining layer which are sequentially bonded and compounded; the re-adhesion-preventing sealing layer is made of an easy-to-tear material.
The material of the adhesive sealing layer is hot melt adhesive, and the adhesive sealing layer is directly bonded with the secondary adhesive sealing layer.
The secondary adhesion preventing layer is a kraft paper layer or a non-woven fabric layer.
The electromagnetic induction heating layer is an aluminum foil layer.

The secondary adhesion preventing layer and the electromagnetic induction heating layer are adhered through strong adhesion glue.
The strong-viscosity glue is polyurethane glue.
The backing layer is a plastic film, a paperboard, a foam board or a plastic board.
The electromagnetic induction heating layer and the back lining layer are bonded through weak-viscosity glue.
The weak-viscosity glue is microcrystalline wax.
After the scheme of the oil field is adopted, the utility model discloses a tear and prevent once more and glue seal type electromagnetic induction and seal gasket has and prevents once more and glue the seal, should prevent once more to glue the seal for easily tearing the material, tears at the user like this the utility model discloses a tear and prevent once more and glue seal type electromagnetic induction and seal gasket when sealing in order to open the container bottleneck, prevent once more and glue the seal and can be torn for glue the seal and prevent once more that the seal part stays the bottleneck, thereby show that this container has been opened, the unable rethread electromagnetic induction of container bottleneck seals the gasket and seals the reseal this moment, thereby plays certain anti-fake effect.

description of reference numerals:
the anti-secondary-adhesion type electromagnetic induction sealing gasket A comprises a secondary-adhesion sealing layer 1, a secondary-adhesion sealing layer 2, an electromagnetic induction heating layer 3, a backing layer 4, strong-adhesion glue 5 and weak-adhesion glue 6.
Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
As shown in fig. 1 to fig. 3, the utility model discloses a prevent gluing again and seal type electromagnetic induction sealing gasket A, it is including gluing compound adhesion sealing layer 1 in proper order, preventing gluing sealing layer 2, electromagnetic induction zone of heating 3 and back sheet 4 once more.
In the utility model, the material of the adhesive layer 1 is hot melt adhesive, and the adhesive layer 1 is coated on the secondary adhesion preventing layer 2 to directly bond the adhesive layer 1 and the secondary adhesion preventing layer 2; therefore, the bonding and sealing layer 2 and the re-bonding prevention layer 2 have high composite strength.
The utility model discloses in, prevent once more to glue seal 2 for easily tearing the material, prevent promptly to glue seal 2 once more and be torn easily, should prevent once more to glue seal 2 specifically can be kraft layer or non-woven fabrics layer.
In the utility model, the electromagnetic induction heating layer 3 generates current to generate heat when being acted by an electromagnetic field, so as to heat the adhesive sealing layer 1 and melt the adhesive sealing layer 1 by heating; the electromagnetic induction heating layer 3 may be specifically an aluminum foil layer. The electromagnetic induction heating layer 3 with prevent gluing sealing layer 2 once more and glue 5 bonds through strong viscidity for the electromagnetic induction heating layer 3 is high with prevent gluing sealing layer 2 combined strength once more. The electromagnetic induction heating layer 3 can be a double-sided corona structure, and the surface tension of the two sides of the electromagnetic induction heating layer 3 is larger than 38 dynes.
The utility model discloses in, back sheet 4 is plastic film, cardboard, foaming board or plastic slab, can play certain intensive supporting role to gluing seal 1, prevent gluing seal 2 once more and electromagnetic induction zone of heating 3 when this back sheet 4 is compound with electromagnetic induction zone of heating 3. The back lining layer 4 and the electromagnetic induction heating layer 3 can be bonded through weak-viscosity glue 6; the weak adhesive 6 is melted when heated and absorbed by the backing layer 4, so that the backing layer 4 is separated from the electromagnetic induction heating layer 3; the weak adhesive 6 may be microcrystalline wax. The backing layer 4 may be printed with some LOGO design as desired by the customer.
