Description
Technical field
The utility model relates to a kind of strip of paper used for sealing for inflating, and relates in particular to a kind of gas-filled film strip of paper used for sealing.
Background technique
Daily inflation class article, as balloon, air-bed, air cushion, gas rod etc., first by its gassy, then secure gas port when use.The method of sealing mainly contains two kinds, and the one, tie up with rope, the 2nd, automatic sealing mouth is installed.Cumbersome by rope strapping, gas replenishment process gas can run outward, and gas is tied up insecure after substituting the bad for the good.Automatic sealing mouth is easy to use, gas replenishment process gas does not run outward, gas only import but no export, gas is substituted the bad for the good and need not be tied up, but common automatic sealing mouth mostly is flexible glue (as bladders) or metal adds Jiao Zui (as tire), this valve volume is large, and cost is high, is not suitable for slim inflatable substrate (as hydrogen balloon, gas rod etc.).
For reducing costs, at present in the inflation of balloon, gas rod, commonly use a kind of inflatable sealing strip, comprise primary diaphragm and the secondary diaphragm made by polyethylene film, the dual-side heat-sealing of primary diaphragm and secondary diaphragm and form filling channel, one end of filling channel is as inflation entrance, and this valve volume is very little, and cost is low, be applicable to various inflatable substrates, particularly ultrathin inflatable substrate (as hydrogen balloon, gas rod etc.).
But, also there is following defect in above-mentioned this inflatable sealing strip: (1) does not arrange inflation inlet, but one end of filling channel is used as to inflation inlet, and this inflation entrance coordinates defective tightness with the conical inflatable head of inflator, easily cause Leakage Gas, inflation difficulty; (2) flap section is not set, need opens primary diaphragm and secondary diaphragm completely, make to inflate entrance and strut the conical inflatable head that can insert inflator and inflate, suitable trouble in operation; (3) dual-side of primary diaphragm and secondary diaphragm only seals by a hot-sealing line, the dual-side of inflatable sealing strip is firm not, easily split, cause gas leakage, particularly, in the time inserting the conical inflatable head of inflator, the conical inflatable head of inflator easily cracks the dual-side of inflatable sealing strip.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of gas-filled film strip of paper used for sealing, and this gas-filled film strip of paper used for sealing cost is low, it is easy, simple to operate, solid and reliable to inflate.The technological scheme adopting is as follows:
A kind of gas-filled film strip of paper used for sealing, comprise primary diaphragm and secondary diaphragm, it is characterized in that: described primary diaphragm comprises flap section, the first trapezoidal gas port section and the first bar shaped air duct sections successively, described secondary diaphragm comprises the second trapezoidal gas port section and the second bar shaped air duct sections successively, the both sides of the edge of the first trapezoidal gas port section, the first bar shaped air duct sections, the second trapezoidal gas port section and the second bar shaped air duct sections are equipped with the first hot-sealing line and the second hot-sealing line, the inner side of the second hot-sealing line in the first hot-sealing line; Secondary diaphragm is stacked on primary diaphragm and at the first hot-sealing line, the second hot-sealing line place and is heat sealing at together.
Together with the first trapezoidal gas port section is heat sealing at the dual-side of the second trapezoidal gas port section and form inflation inlet, expand into funnel-like; Together with the first bar shaped air duct sections is heat sealing at the both sides of the second bar shaped air duct sections and form gas channel.This gas-filled film strip of paper used for sealing structurally or mainly comprises primary diaphragm and secondary diaphragm, and cost is equally very low; Because the first trapezoidal gas port section forms inflation inlet together with being heat sealing at the dual-side of the second trapezoidal gas port section, inflation inlet expands into funnel-like, and the conical inflatable head of inflator coordinates with inflation inlet closely, can not leak gas, and it is quite easy to inflate; Because a side of inflation inlet is provided with flap section, open inflation inlet ratio at flap section place and be easier to, and the conical inflatable head of inflator is more easily inserted in inflation inlet along flap section, operate quite simple; Because the first trapezoidal gas port section, the first bar shaped air duct sections, the second trapezoidal gas port section and the second bar shaped air duct sections are all in the first hot-sealing line, the second hot-sealing line place heat seal, the dual-side of inflation inlet and gas channel all seals by two hot-sealing lines, be not easy to break, leak gas, the conical inflatable head of inflator can not crack inflation inlet yet, more solid and reliable in structure.
As preferred version of the present utility model, described flap section is provided with multiple frosted shape salient points near the first bar shaped air duct sections place.By multiple frosted shape salient points are set in flap section, finger, along two film edge of frosted shape salient point friction inflation inlet, more easily opens inflation inlet, and frosted shape salient point, owing to being arranged in flap section, can't affect inflation.
As preferred version of the present utility model, on described primary diaphragm, be also provided with identification pattern layer, identification pattern layer extends to the first bar shaped air duct sections from flap section through the first trapezoidal gas port section.By identification pattern layer is set on primary diaphragm, make the easier identification of inflation inlet, pick up conveniently gas-filled film strip of paper used for sealing, just can be placed on the inflatable toys such as balloon, gas rod and carry out involution, it is quite easy to operate.
As the further preferred version of the utility model, described identification pattern layer is directly printed on primary diaphragm.Identification pattern layer adopts the directly mode of printing, saves bonding process, further reduces production costs.
As the further preferred version of the utility model, the part of described identification pattern layer in the middle of the first trapezoidal gas port section is provided with sealing mark.By on identification pattern layer, sealing mark being set, as long as the involution position of the inflatable toys such as the sealing mark of gas-filled film strip of paper used for sealing and balloon, gas rod is aimed at, just can carry out involution, simpler in operation.
Compared with prior art, tool has the following advantages the utility model:
This gas-filled film strip of paper used for sealing structurally or mainly comprises primary diaphragm and secondary diaphragm, and cost is equally very low; Because the first trapezoidal gas port section forms inflation inlet together with being heat sealing at the dual-side of the second trapezoidal gas port section, inflation inlet expands into funnel-like, and the conical inflatable head of inflator coordinates with inflation inlet closely, can not leak gas, and it is quite easy to inflate; Because a side of inflation inlet is provided with flap section, open inflation inlet ratio at flap section place and be easier to, and the conical inflatable head of inflator is more easily inserted in inflation inlet along flap section, operate quite simple; Because the first trapezoidal gas port section, the first bar shaped air duct sections, the second trapezoidal gas port section and the second bar shaped air duct sections are all in the first hot-sealing line, the second hot-sealing line place heat seal, the dual-side of inflation inlet and gas channel all seals by two hot-sealing lines, be not easy to break, leak gas, the conical inflatable head of inflator can not crack inflation inlet yet, more solid and reliable in structure.In addition, owing to being provided with identification pattern layer, on identification pattern layer, sealing mark is set, the involution of the inflatable toys such as gas-filled film strip of paper used for sealing and balloon, gas rod is more prone to.
