Abstract

The utility model relates to a package sealing technology, in particular to a dual-sheet separated electromagnetic induction sealing gasket. A common electromagnetic induction sealing gasket is of a single-sheet type, and loses the performance of resealing a bottleneck once being torn off from the bottleneck. The dual-sheet separated electromagnetic induction sealing gasket disclosed by the utility model is formed by compounding an inductive sealing layer, a weak adhesive and a press seal layer, wherein the inductive sealing layer is formed by compounding a plastic film and an aluminum foil; the plastic film is bonded with the aluminum foil by using a strong adhesive; the weak adhesive is positioned between the aluminum foil and the press seal layer; the press seal layer is made of a paperboard or a foam material. According to the dual-sheet separated electromagnetic induction sealing gasket disclosed by the utility model, the sealing gasket is partitioned into two parts, one part serving as the inductive sealing layer is left on the bottleneck and is tightly bonded with the bottleneck while the other part serving as the press seal layer is left in a bottle cap after sealing is completed; the press seal layer can play a role in sealing the bottleneck after the inductive sealing layer is torn off.

Description

Biplate Split type electric magnetic induction gasket seal

Technical field

The utility model relates to packaging and sealing technology, relates in particular to a kind of biplate Split type electric magnetic induction gasket seal.

Background technology

In life, have many bottled products, 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 with electromagnetic induction gasket seal sealing bottleneck.

Common electromagnetic induction gasket seal is one chip, after tearing, want again this gasket seal bottleneck, just must use electromagnetic induction coil to heat this pad, and need by other instruments smooth this pad could be again cannot bottleneck, these equipment and instrument do not possess Portability, very unrealistic concerning customer.So to say that the electromagnetic induction gasket seal of one chip has just lost the performance that again seals bottleneck after bottleneck is torn, and in bottle, article are easily subject to the pollution of bacterium and magazine.

In view of this, the inventor proposes a kind of electromagnetic induction gasket seal of biplate separation type, to solve the deficiency of existing one chip electromagnetic induction gasket seal.

Utility model content

The purpose of this utility model is to provide a kind of biplate Split type electric magnetic induction gasket seal, after sealing pad is torn, still can play sealing effectiveness to bottleneck.

In order to reach above-mentioned purpose, the technical solution of the utility model is:

Biplate Split type electric magnetic induction gasket seal, by induction sealing layer, weak adhesion agent and press seal layer, be composited, induction sealing layer is composited by plastic film and aluminium foil, between plastic film and aluminium foil, with strong rubber stick, glued joint, weak adhesion agent is between aluminium foil and press seal layer, and press seal layer adopts cardboard or expanded material.

Peel strength≤0.08 ~ the 0.10KN/m (thousand Newton/meter) of described weak adhesion agent.

Peel strength >=the 0.22KN/m of described strong rubber stick (thousand Newton/meter).

Adopt after such scheme, the utility model biplate Split type electric magnetic induction gasket seal is because be divided into two parts, after sealing completes, one is induction sealing layer, stay on bottleneck and combine closely with it, another part is press seal layer, stays in bottle cap, this press seal layer, after induction sealing layer is torn, still can play sealing effectiveness to bottleneck.

Label declaration

Induction sealing layer 10 plastic film 11 strong rubber stick 12 aluminium foil 13

Weak adhesion agent 20 press seal layer 30 bottleneck 40 bottle cap 50.

The specific embodiment

As shown in Figure 1 to Figure 3, a kind of biplate Split type electric magnetic induction gasket seal that the utility model discloses, is composited by induction sealing layer 10, weak adhesion agent 20 and press seal layer 30.Induction sealing layer 10 is gluedd joint and forms by strong rubber stick 12 by plastic film 11 and aluminium foil 13.Weak adhesion agent 20, between aluminium foil 13 and press seal layer 30, is glued together aluminium foil 13 and press seal layer 30, thereby induction sealing layer 10 and press seal layer 30 is combined into one.

The material mark of plastic film 11 is identical with the material mark of bottleneck 40, the material of the identical trade mark, its physicochemical property is identical, after being conducive to plastic film 11 and being heated rapidly and bottleneck 40 fuse; The material of the identical trade mark, its chemical composition approaches, and prevents from generating in alloying process poisonous and hazardous material.

Aluminium foil 13 and electromagnetic induction coil induction, the inner eddy current that forms, produces joule heat, heating of plastic film 11.

Strong rubber stick 12 glueds joint plastic film 11 and aluminium foil 13, its peel strength >=0.22KN/m (thousand Newton/meter).On the one hand, when implementing electromagnetic induction sealing, play and glued joint and the evenly effect of conduction heat, make plastic film 11 and bottleneck 40 fusions evenly, form sealing uniformly; On the other hand, after implementing electromagnetic induction sealing, can prevent that aluminium foil 13 from coming off, make aluminium foil 13 plastic covering film 11 all the time, prevent that plastic film 11 is directly exposed to outside, play the effect of secondary seal.

Peel strength≤0.08 ~ the 0.10KN/m (thousand Newton/meter) of weak adhesion agent 20, can peel off down press seal layer 30 at an easy rate from aluminium foil 13.

Press seal layer 30 adopts expanded material to make, and has elasticity.When implementing electromagnetic induction sealing, press seal layer 20 plays the effect of supporting this embodiment packing seal and unfolding aluminium foil 13 and plastic film 11.Implement after electromagnetic induction sealing, press seal layer 20 is peeled off down from aluminium foil 13, stays in bottle cap, and plastic film 11, aluminium foil 13 and strong rubber stick 12 are stayed on bottleneck as induction sealing layer 10.When tearing induction sealing layer 10, bottleneck loses sealing, and induction sealing layer 10 is difficult to again as sealing; At this moment tighten bottle cap 50, stay the extruding that press seal layer 20 in bottle cap is subject to bottle cap 50 and bottleneck 40, elastic deformation occurs, fill up the space between bottleneck 40 and press seal layer 20, form sealing pair, realize sealing effectiveness.

Biplate Split type electric magnetic induction gasket seal shown in the present embodiment is divided into induction sealing layer 10 and press seal layer 20 two parts; implement after electromagnetic induction sealing; induction sealing layer 10 is stayed on bottleneck 40; press seal layer 20 is stayed in bottle cap 50; this press seal layer 20 is after induction sealing layer 10 is torn; still can play sealing effectiveness to bottleneck 40, still can protect bottle interior article to avoid the pollution of bacterium and impurity in air.

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 departing from patent category of the present utility model.
