Abstract
The utility model discloses a pressure-sensitive sealing gasket. The sealing gasket comprises a back lining layer and a pressure-sensitive adhesive layer, wherein the pressure-sensitive adhesive layer is uniformly coated on the back lining layer. In the utility model, a bottle cap is directed at a bottle mouth to press down the sealing gasket, and the bottle mouth is sealed by the back lining layer through the pressure-sensitive adhesive layer. Therefore, the sealing gasket is not required to be heated by electromagnetic induction, can be used for sealing more conveniently, and has good sealing and bonding effects; besides, if the back lining layer adopts an expanded polystyrene plate, the back lining layer of the gasket can be easily pricked and torn for use, so that the use is very convenient.
Description
Technical field
The utility model belongs to the packing technique field, relates to a kind of pressure sensitive seal gasket.
Background technology
In daily life, many fields all can relate to the packing of sealing, for example food, cosmetics and medicine field etc., and the kind of seal gasket has various ways, is that metal aluminum foil and joint filling material are combined with each other by hot melt adhesive as the electromagnetic induction seal gasket, and aluminium foil generates heat by electromagnetic induction, with joint filling material and the mutual bonding leak free purpose that reaches of bottleneck, because need electromagnetic induction heating, operate cumbersomely, and also relatively be not easy to tear this seal gasket in using; Also have other seal gasket, but various seal gasket effects is all undesirable.
In view of this, the inventor studies the structure of seal gasket, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of pressure sensitive seal gasket, to reach the purpose that realizes the seal gasket leak tightness conveniently, effectively.
A kind of pressure sensitive seal gasket is made up of back sheet and pressure-sensitive adhesive layer, and this pressure-sensitive adhesive layer is coated on this back sheet equably.
Described back sheet adopts the foamed polystyrene sheet material.
After adopting such scheme, the utility model is because be made up of back sheet and the pressure-sensitive adhesive layer that is uniformly coated on this back sheet, the pressure that produces bottle cap the time by lock when sealing makes pressure-sensitive adhesive layer produce bonding force, pressure-sensitive adhesive layer and bottleneck closely bond and reach the sealing effectiveness of back sheet to bottleneck together then, therefore, seal gasket of the present utility model does not need electromagnetic induction heating, seal more convenient, the sealing adhesive effect good.In addition, if back sheet adopts the foamed polystyrene sheet material, can easily poke the pad back sheet during use it is torn, it is very convenient to use.

The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As Fig. 1 is a kind of pressure sensitive seal gasket of the present utility model, is made up of back sheet 1 and pressure-sensitive adhesive layer 2, and this pressure-sensitive adhesive layer 2 is coated on this back sheet 1 equably.
Described back sheet 1 adopts the foamed polystyrene sheet material to make, and can adopt that expansion ratio is low, the foam sheet of good toughness, thin thickness makes.
The pressure sensitive adhesive of described pressure-sensitive adhesive layer 2 is made up of EVA, polyisobutene, ceresine wax etc., is the solid of colorless and odorless.
Pressure sensitive adhesive after fusion under 70～90 ℃ the temperature, is applied on polystyrene (EPS) foam sheet uniformly, is pressure sensitive seal gasket of the present utility model after the cooling.
Pressure-sensitive adhesive layer 2 in the utility model product is not when being under pressure, and the pressure sensitive adhesive initial bonding strength is lower, generally can not bond together with other article, but be subjected to big pressure the time, then pressure sensitive adhesive can produce very strong bonding force.As shown in Figure 2, to bottle lock bottle cap 3 time, locking closure pressure can make pressure sensitive adhesive produce very big bonding force, this pressure sensitive adhesive will with the bonding together of bottleneck close and firm, make to the utlity model has the better seal effect.
Seal gasket of the present utility model does not need electromagnetic induction heating, seals more convenient realization, and the sealing adhesive effect is good, and can easily poke back sheet 1 in using it is torn, and it is very convenient to use.
The above is preferred embodiment of the present utility model only, is not the qualification to the utility model practical range, and all variation and modifications of doing according to key points in design of the present utility model all fall into its protection domain.
Claims (2)
1. pressure sensitive seal gasket, it is characterized in that: be made up of back sheet and pressure-sensitive adhesive layer, this pressure-sensitive adhesive layer is coated on this back sheet equably.
2. a kind of pressure sensitive seal gasket as claimed in claim 1 is characterized in that: described back sheet adopts the foamed polystyrene sheet.
