Abstract
The utility model discloses an electro-magnetic induction sealing gasket which is formed by compounding a heat-sealing layer, a first adhesive layer, an aluminum foil layer, a second adhesive layer and a back-lining layer. The first adhesive layer is located between the heat-sealing layer and the aluminum foil layer, the second adhesive layer is located between the aluminum foil layer and the back-lining layer, the first adhesive layer and the second adhesive layer are powerful adhesives, and the back-lining layer is a paper board or a foaming material. After adopting the technical scheme, the defect that articles are stored in an adhesive polluted bottle does not exist. The heat-sealing layer is integrally welded with a bottle opening after being molten, and the tight-combination sealing effect is achieved. The powerful adhesives can ensure the sealing reliability, and the articles contained in the bottle are prevented from being polluted by bacteria and impurities in the air.
Description
Technical field
The utility model relates to packaging and sealing technology, relates in particular to a kind of electromagnetic induction gasket seal.
Background technology
Many bottled products are arranged in life, and as beverage, cosmetics, medicine, reagent etc., these products easily suffer the pollution of airborne bacterium and impurity, need airtight preservation, with anti-metamorphic.Seal-packed a kind of effective means is to seal the edge of bottleneck with gasket seal, and common method is to use glue sealing, with glue, is applied to the sticky gasket seal that affixes in bottleneck edge.
Adopt the method for glue sealing, on the one hand, need to wait for that the glue solidifies, makes production efficiency low; On the other hand, once that glue is smeared is inhomogeneous, easily cause sealing inhomogeneous, the local situation of leaking that occurs of bottleneck, lose the effect of article-containing in the protection bottle.More seriously, glue can flow in bottle and contact with article, or in bottle, an article-containing can be subject to rocking with glue and contact, once a glue contact bottle interior article-containing certainly will pollute it, affects the quality of product, causes the product calcellation of going bad.
In view of this, the inventor proposes a kind of new construction that does not rely on glue sealing, just can play tight failure-free sealing effectiveness, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of electromagnetic induction gasket seal, makes the combination of electromagnetic induction gasket seal and bottleneck not rely on glue just can realize tight failure-free sealing.
In order to reach above-mentioned purpose, the technical solution of the utility model is:
The electromagnetic induction gasket seal, be composited by hot sealing layer, the first glue-line, aluminium foil layer, the second glue-line and back sheet; The first glue-line is between hot sealing layer and aluminium foil layer, and the second glue-line is between aluminium foil layer and back sheet, and the first glue-line and the second glue-line are potent adhesion agent.
Described back sheet is cardboard or expanded material.
The peel strength of described potent adhesion agent >=0.22 KN/m (thousand Newton/meter).
After adopting such scheme, the utility model compared to the prior art: there is no glue between hot sealing layer and container, do not have the shortcoming of article-containing in the glue pollution bottle; Sealing relies on the electromagnetic induction heating hot sealing layer, after making hot sealing layer fusing and the bottleneck welding be integrated, reach the sealing effectiveness of combining closely, adopt potent adhesion agent, can effectively avoid coming off of aluminium foil layer and back sheet, thereby guarantee the reliability of sealing, the tight sealing of the utility model has avoided the interior article-containing of bottle to be subject to the pollution of airborne bacterium and impurity.

Fig. 1 is that the utility model embodiment seals schematic diagram;
Fig. 2 is the utility model embodiment enlarged diagram.
Label declaration
Bottleneck 6 electromagnetic induction cappers 7.
The specific embodiment
As shown in Figure 1, the present embodiment electromagnetic induction gasket seal, be composited by hot sealing layer 1, the first glue-line 2, aluminium foil layer 3, the second glue-line 4 and back sheet 5.The first glue-line 2 is between hot sealing layer 1 and aluminium foil layer 3, and the second glue-line 4 is between aluminium foil layer 3 and back sheet 5.
The first glue-line 2 is potent adhesion agent, can select the potent PP adhesion agent that is easy to buy from market, or selects peel strength >=0.22 KN/m(thousand Newton/meter) potent adhesion agent.The first glue-line 2 glueds joint hot sealing layer 1 and aluminium foil layer 3.Because the peel strength of potent adhesion agent is high, at first can be in implementing seal process, avoid aluminium foil layer 3 to come off or and hot sealing layer 1 laminating not tight, further avoid conducting heat inhomogeneous, make hot sealing layer 1 thermally equivalent and fusing, guarantee that sealing is evenly reliable; Secondly can be after implementing sealing, prevent that aluminium foil layer 3 and hot sealing layer 1 from peeling off, make the tight cover heating sealing 1 of aluminium foil layer 3, prevent that hot sealing layer 1 is directly exposed to outside, play the effect of secondary seal.If the first glue-line 2 is not potent adhesion agent or is not adhesion agent, hot sealing layer 1 and aluminium foil layer 3 just rely on weak gluing connect or electrostatic adherence together with; In implementing seal process, aluminium foil layer 3, easily because heating comes off, causes sealing inhomogeneous; After implementing sealing, aluminium foil layer 3 easily comes off, and causes hot sealing layer 1 to lack the covering of aluminium foil 3 and, outside being directly exposed to, loses secondary seal and protection.
Aluminium foil layer 3 and induction coil generation electromagnetic induction, induced inside goes out eddy current, produces joule heat, and this joule heat is transmitted on hot sealing layer 1 by the first glue-line 2, heat hot sealing 1.
The second glue-line 4 is potent adhesion agent, can select the potent PP adhesion agent that is easy to buy from market, or selects peel strength >=0.22 KN/m(thousand Newton/meter) potent adhesion agent.The second glue-line 4 glueds joint back sheet 5 and aluminium foil layer 3; prevent that back sheet 5 and aluminium foil layer 3 from peeling off, make back sheet 5 closely cover aluminium foil layer 3, prevent that aluminium foil layer 3 is directly exposed to outside; protection aluminium foil layer 3 is not oxidated and damaged, further avoids outside hot sealing layer 1 is directly exposed to.
Heat aluminium foil layers 3 with electromagnetic induction capper 7 in the present embodiment, the further heat hot sealing 1 of aluminium foil layer 3, hot sealing layer 1 fusing and bottleneck are combined closely, and between hot sealing layer 1 and bottleneck 6, there is no glue, do not have the shortcoming of article-containing in the glue pollution bottle.Potent adhesion agent can be avoided aluminium foil layer 3 to come off or be not tight with hot sealing layer 1 laminating, makes hot sealing layer 1 thermally equivalent and fusing, guarantees that sealing evenly reliably.The present embodiment makes the combination of electromagnetic induction gasket seal and bottleneck not rely on glue just can realize tight failure-free sealing.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not breaking away from patent category of the present utility model.
