Abstract
The utility model relates to one and had both had foaming layer function in bottle mouth sealing pad, has again the functional bottle mouth sealing pad intermediate of hot sealing layer function in bottle mouth sealing pad, hot sealing layer hot melt adhesive in foaming layer and bottle mouth sealing pad in bottle mouth sealing pad.Advantage: one is both had foaming layer function in bottle mouth sealing pad, has again hot sealing layer function in bottle mouth sealing pad; Two is the laminar textures changing bottle mouth sealing pad in background technology, makes aluminium foil layer directly and polyester compound, and thin by functional layer thickness; not only make electromagnetic induction efficiency high; and the power needed for reduction electromagnetic induction, both protected environment, favourable people operative employee's is healthy again.
Description
Technical field
The utility model relates to one and had both had foaming layer function in bottle mouth sealing pad, has again the functional bottle mouth sealing pad intermediate of hot sealing layer function in bottle mouth sealing pad, belongs to one layer in the middle of bottle mouth sealing pad and manufactures field.
Background technology
CN1970289A, title " high air tightness foamed PE composite gasket ", be bonded together successively mutually by foaming PE, art paper, aluminium foil, these four layers of materials of polyvinylidene chloride.The main component of pad is foaming PE material, has the elasticity of height, can meet the size between various different bottle mouth, ensure sealing effectiveness.Its weak point: the foaming PE layer in this Composition spacer and polyvinylidene chloride are the only layer of difference, adopt and be combined with each other by aluminium foil and adhesives, not only complex process, manufacturing cost is high, and made spacer thickness is thick, and during Electromagnetic Heating, heat conduction efficiency is low, thus cause electromagnetic induction heating power large, energy consumption is high, to environment, directly affects the healthy of operative employee.
Utility model content
Design goal: avoid the weak point in background technology, designs a kind of both foaming layer and hot sealing layer unifications and the functional bottle mouth sealing pad intermediate having that thickness is thin, heat transfer is fast, electromagnetic heating power is low, energy consumption is little, reduce amount of electromagnetic radiation and low cost of manufacture.
Design plan: in order to realize above-mentioned design goal.In bottle mouth sealing pad, the design of hot sealing layer hot melt adhesive in foaming layer and bottle mouth sealing pad, is technical characteristics of the present utility model.The object of such design is: because the application's foaming layer is polyethylene foam layer, and polyethylene is typical thermoplastic plastic, it and polyolefin layer hot sealing layer have good hot melt compatibility, affine feature both the utility model utilizes, two multiple being integrated by superposable die are obtained functional bottle mouth sealing pad intermediate, not only there is the function of foaming layer, and there is the function of hot sealing layer, the more important thing is and the two copolymerization mold pressing is integrated, not only without the need to lining cement compound, and reduce the thickness of seal gasket, make the electromagnetic induction power reduction that seal gasket is required in the process of sealing, energy consumption reduces, amount of electromagnetic radiation weakens, both environment was protected, favourable people operative employee's is healthy again.
Technical scheme: a kind of functional bottle mouth sealing pad intermediate, hot sealing layer hot melt adhesive in foaming layer and bottle mouth sealing pad in bottle mouth sealing pad.
The utility model is compared with background technology, and one is both had foaming layer function in bottle mouth sealing pad, has again hot sealing layer function in bottle mouth sealing pad; Two is the laminar textures changing bottle mouth sealing pad in background technology, makes aluminium foil layer directly and polyester compound, and thin by functional layer thickness; not only make electromagnetic induction efficiency high; and the power needed for reduction electromagnetic induction, both protected environment, favourable people operative employee's is healthy again.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of functional bottle mouth sealing pad intermediate.
Fig. 2 is the structural representation of the bottle mouth sealing pad be made up of Fig. 1.
Detailed description of the invention
Embodiment 1: with reference to accompanying drawing 1.A kind of functional bottle mouth sealing pad intermediate, foaming layer 1 and hot sealing layer 2 hot melt adhesive in bottle mouth sealing pad in bottle mouth sealing pad.Described foaming layer 1 is polyethylene foam layer.Described hot sealing layer 2 is polyolefin layer.
Embodiment 2: with reference to accompanying drawing 2.On the basis of embodiment 1, aluminium foil 4 two sides respectively with bottle mouth sealing pad surface layer (polyester layer) 3 and functional bottle mouth sealing pad intermediate (1,2) compound.Its method for making, first by polyethylene foam, then the polyethylene melt after foaming and polyolefin molten mass to be inserted respectively in superposable die in polyethylene die cavity and polyolefin die cavity, then polyethylene and polyolefin are extruded by composite die moulded head, the functional bottle mouth sealing pad intermediate that one side is polyethylene foam face, one side is polyolefin face can be obtained.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to mentality of designing of the present utility model; but these text descriptions; just the simple text of the utility model mentality of designing is described; instead of the restriction to the utility model mentality of designing; any do not exceed the utility model mentality of designing combination, increase or amendment, all fall in protection domain of the present utility model.
Claims (3)
