Abstract
The utility model discloses an electromagnetic induction seals gasket with put forth effort part, materials compound forms by the multilayer, and it up is down that heat -seal layer, aluminium foil layer, insulating layer, film are to buckled ply and film top layer, through the glue bonding between each layer in proper order to follow. The utility model discloses an aluminium foil layer is generating heat behind electromagnetic induction, and transfer heat gives the heat -seal layer, and melt on messenger's heat -seal layer, plays the sealed effect of bonding bottleneck. Seal that the back forms put forth effort the part about by the bonding of two -layer PET film form, can be left or right or wantonly other directions reveal the gasket, very firm, difficult rupture. This electromagnetic induction seals the gasket, and to be applicable to the bottleneck in medicine, health products, food, flavouring, cosmetics, articles for washing and so on field sealed, has thoroughly solved current bottleneck and sealed the problem that the gasket is difficult to to reveal, and application prospect is wide.
Description
Technical field
This utility model relates to seal gasket technical field, specifically, relates to a kind of electromagnetic induction seal gasket。
Background technology
Seal gasket is more and more general in the use of industry-by-industry, such as medicine, health product, food, flavoring agent, cosmetics, articles for washing etc.。Current industrial most employing electromagnetic induction seal gasket; by electromagnetic induction sealing device, the aluminium foil layer of pad is carried out electromagnetic induction heating; make the plastic film melted by heat of pad and bottleneck contact surface; realize pad and bottle sealing; cut off the material in bottle face and air contact, play the effect protecting the material in bottle。
But current seal gasket is all not provided with opening the parts of putting forth effort of pad, or it is firm not to put forth effort parts, this makes user very inconvenient when opening pad, often to use edge tool to cut pad, thus dangerous hidden danger。
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of with putting forth effort parts and firm electromagnetic induction seal gasket。
To achieve these goals, this utility model adopts the following technical scheme that
A kind of electromagnetic induction seal gasket, is composited by multilayer material, be successively from the bottom up hot sealing layer, aluminium foil layer, thermal insulation layer, thin film to fold and film top layer, bond through glue between each layer。
The effect of hot sealing layer is to play bonding bottle sealing effect after melted by heat。
The effect of aluminium foil layer is to generate heat after electromagnetic induction, transmits heat to hot sealing layer, makes hot sealing layer fusing bonding bottleneck。
The effect of thermal insulation layer is: 1, isolation aluminium foil layer heat passes to thin film to fold and film top layer, it is to avoid fold and film top layer are heated thin film and plastic bottle lid bonds, and impact is uncapped。2, give hot sealing layer and aluminium foil layer provides deflection, not curling after making coiled material puncher for spacer strip be cut into circle。3, by controlling the thickness of the whole pad of thickness scalable of thermal insulation layer。
The effect of fold is by thin film: after pad is punched out, and can be formed and put forth effort parts。What namely the semi-circular portions of fold and film top layer laminating was become pad top by thin film puts forth effort part。
As preferably, in above-mentioned electromagnetic induction seal gasket, between aluminium foil layer and thermal insulation layer, it is arranged to strengthen the thin layer of deflection or thickness。
Compared with prior art, this utility model has the advantages that
Of the present utility model with putting forth effort the electromagnetic induction seal gasket of parts by multilayer material compound, be successively from the bottom up hot sealing layer, aluminium foil layer, thermal insulation layer, thin film to fold and film top layer, after glue bonds, arrive the peel strength of more than 2N/10mm between each layer。Aluminium foil layer, generating heat after electromagnetic induction, transfers heat to hot sealing layer, makes hot sealing layer melt, and plays bonding bottle sealing effect。Then being punched out according to bottleneck size by pad, fold is raised formation along broken line and is puted forth effort parts by die-cut rear film, and pulling is puted forth effort parts and just can be opened pad easily。The parts of putting forth effort formed after the sealing of this electromagnetic induction seal gasket are bonded by left and right two-layer PET film, it is possible to the left or to the right or arbitrarily pad is opened in other directions, very firm, is not easily broken。This electromagnetic induction seal gasket is applicable to the bottle sealing in medicine, health product, food, flavoring agent, cosmetics, articles for washing etc. field, thoroughly solves the problem that existing bottle mouth sealing pad is difficult to open, has a extensive future。

Fig. 2 is sheet of electromagnetic induction seal gasket plane and die-cut schematic diagram；
Fig. 3 is the sectional view that electromagnetic induction seal gasket puts forth effort that parts start；
Fig. 4 puts forth effort the outside schematic diagram that parts start。
Detailed description of the invention
As it is shown in figure 1, a kind of electromagnetic induction seal gasket, multilayer material be composited, be successively from the bottom up hot sealing layer 1, aluminium foil layer 2, PET film layer 3, thermal insulation layer 4, PET film to fold 5 and PET film top layer 6, bond through glue 7a between each layer。After glue bonds, the peel strength of more than 2N/10mm is arrived between each layer。
The preparation method of above-mentioned electromagnetic induction seal gasket, comprises the steps:
Step 1: use dry compound machine to bond after thin layer 3 gluing of coiled material with aluminium foil layer 2, prepare the first complex 12；
Step 2: by step 1 gained the first complex 12, by bonding with hot sealing layer 1 after dry compound machine gluing, prepares the second complex 13；
Step 3: by the thin film of coiled material to fold 5 and film top layer 6 respectively through, after gluing, bonding with thermal insulation layer 4, prepares the 3rd complex 16；
Step 4: after the second complex 13 gluing of rolling, bond with the 3rd complex 16, prepares electromagnetic induction seal gasket 11。
As in figure 2 it is shown, during work, on automatic production line, step 1: using the thin film of coiled material electromagnetic induction seal gasket to the broken line of fold 5 as diameter, adopt circular die to be punched out, prepare the circular seal pad putting forth effort parts 8 with top；
Step 2: loaded towards bottle cap by the top layer of circular seal pad, then pins bottleneck by the bottle cap with seal gasket；Finally use electromagnetic induction that aluminium foil layer 2 is generated heat, transfer heat to hot sealing layer 1 so that hot sealing layer 1 fusing bonding bottleneck seals；After natural cooling, lid of outwarding winding, catch and put forth effort parts 8 and just can open circular seal pad。Electromagnetic induction seal gasket puts forth effort sectional view such as Fig. 3 that parts start；Put forth effort outside schematic diagram such as Fig. 4 that parts start。
