Description

A kind of improved type air-packing device

Technical field

The utility model relates to the three-dimensional aeroseal packing device that utilizes self-adhering (check valve) technical design to produce; can use at electronic product glass ware, precision instrumentation; workmanship, precious fragile such as printing consumables and safety guard-safeguard performance require than higher various fields.The utility model be a kind ofly have anti-extruding, anti-vibration, sealed damp-proof, anti-falling fallen and the novel environment friendly packing of integrated protection performance such as buffering, can be used as in the transportation protection, filling, the part of article or the partiting pad of significant points and the omnibearing buffering package of article or by printing direct use in the sale external packing as article.

Background technology

The trend of globalization of enterprise strengthens the transportation range of product from the grown place to area of consumption day by day, causes for the protective packaging demand in the transportation also fast-developing simultaneously.Traditional polystyrene foamed (EPS) and polyethylene foams (EPE) based article must use at manufacturer's foaming or through just being transported to the user after the processed, the bulky very inconvenience transportation and the storage of the foamed plastic after the moulding.The foaming in place class material that transports for convenience and develop mainly is to utilize the Polyurethane foam goods, expands and forms on the content next door and protect model.But the price of material is higher relatively and the equipment at scene had certain requirements simultaneously require to be not suitable for the inner packing of large-scale pipeline product such as electronic product at workman's efficient and working strength.Simultaneously, show serious many drawback days of polystyrene foamed (EPS) based article, become for the people all dislike " white pollution ".Relatively only at the buffer product of transit link short-term use, the offal treatment of permanent polyphenyl blister pack brings gross pollution to environment.Burning produces noxious gas, and heap buries the destruction that produces geologic framework because of not corroding.The concern of government and customer's environmental pollution problem in recent years will be limited to the development of this series products.Simultaneously, packing in the market almost are limited by the bulky influence of packing itself invariably, traffic cost makes these materials closely to sell, thereby can't form scale and benefit.

Along with the fast development of soft-plastic material, the design that increasing industry can be benefited bring with this material behavior and the expansion of function.Traditional gas flush packaging utilizes hot sealing process to form simple round dot (BUBBLE WRAP, bubble pad), block or cylindric usually.Bubble is paid somebody's debt and expected repayment later and can be transported by being packaged as coiled material, but other shape product must form air bag at the heat-sealing equipment that uses the on-site installation complexity.Because the protection effect and the shape-variable of this series products are limited, so operable field mostly is pad or the filling space is used.Simultaneously, to protect the gas time be not very long because the fugitiveness of the use of material and hot sealing process causes.Therefore, limited to for a long time always and utilize air as the development of the packaging product of buffer medium.

Walker in the document (1981) Official Gazette of the United State's Patent Office 4191211,4708167 valve body and the combinations that utilize soft-plastic material to make all on the books of Koyanagi (1987) Official Gazette of the United State's Patent Office are used for making as products such as water bag, coffee bag, balloon toys as plastic sheeting or rubber type of material.Simple softly mould the passage that structure can provide air admission or discharge but stop the seepage of liquid or gas or enter by this, forming one can store fluid or the storage space of energy deaeration.On the basis of this theory, use different materials to can be used for different fields such as life jacket and be used for preserving the sealing arrangement of fluid, as bladders.2005, the relevant feasibility study that utilizes air as buffering that Fu Jingfang delivers at " packing and food machinery " magazine at " Packaging Engineering " and Liu Gong etc. was for the utility model provides good theoretical foundation.

On November 22nd, 2006, disclosed Chinese patent application 200510025833.4 disclosed a kind of self-adhesive nonreturn air package material and manufacture method thereof, this utility model relates to a kind of self-adhesive nonreturn air package material and manufacture method thereof, these packing are made up of four layers of plastic sheeting, bonding through local heat-sealing, form the space that to deposit air, utilize the viscosity and the action of air pressure of film self, air can not be run spill, and in the lasting preservation in this space, air and film have been formed a kind of vibration resistance that has jointly, anti-extruding, the self-adhesive nonreturn air package material of functions such as protection against the tide.

On November 21st, 2007, disclosed Chinese patent application 200580016507.5 disclosed a kind of structure of air-packing device of the shock absorbing capability with improvement, and this device has the air-packing device of product shock absorbing capability, that be used for protecting container case of improvement.This air-packing device comprises: first and second plastic sheetings, thus they are produced a plurality of air chambers in the pre-position by bonding, and each air vessel has the air chamber that a plurality of serial connections link to each other; Be arranged on corresponding air vessel the entrance, be used to make pressurized air along forwards to a plurality of check valves that flow; With public ground of described a plurality of check valves bonded assembly air intake; Be formed on the heat-seal flanges on the lateral edges of air-packing device.Pass through post heat-seal treatment, predetermined point on the described air vessel and heat-seal flanges are bonded in together, thereby when air-packing device was charged into pressurized air, generation had container portions that is used to package the product in opening wherein and the cushion part that supports described container portions.

The disclosed air-packing device of above-mentioned patent application as shown in Figure 1; air by main channel 1 in check valve 2 enters each air chamber 3; the diameter of air chamber 2 is all basic identical; inflate body and the maximum pressure that born basic identical; after inflation is finished; the size of the object that its inner space can hold is basic for certain; if the packing object volume is excessive; can't be placed in the air-packing device; object volume is too small if institute holds packing, and then this object can produce play, bump in air-packing device; break up air-packing device, thereby can't realize the buffer protection function of packing.Apart from little packing object (as 14 cun and 15 cun notebook PCs), need two cover production technology and moulds for those volume differences, increased productive costs greatly.

On the other hand, because the diameter of each air chamber is basic identical, the pressure that is born is also basic identical, and when packaged object fell, it is stressed that all air chambers are equivalent to uniform plane.The power that can bear for the structure design of the extremely thin again product of square type but is not average, and is the most fragile as liquid crystal panel in the middle of its plane.If evenly stressed, the object antagonistic force that the middle part of back plane can bear that falls is minimum relatively, so evenly stressed buffering effect difference causes partial failure easily.

The utility model content

For addressing the above problem, the utility model provide a kind of be applicable to different size packing object and can have strengthen buffering effect greatly, and can reduce follow-on air-packing device of convenient transportation processing of the volume of packaged object.

For achieving the above object, the utility model adopts following technical scheme:

A kind of improved type air-packing device, the space that can deposit air that forms by two-layer thermoplastic film, comprise a plurality of independently sealed air chamber and main channel, there is a gas feed main channel, a check valve and the main channel UNICOM of each sealed air chamber by constituting by double-layer films, it is characterized in that the full diameter of described sealed air chamber varies in size.

Because the full diameter size of air chamber is different, after the inflation, be positioned at bigger air chamber and the less air chamber of full diameter of full diameter on the one side, form corrugated, resemble that layer fluting board structure in the Packaging Box, increased the load-carrying capacity of packing device greatly.

Because the air chamber diameter is big more; so the just big buffer capacity that air compression produces when pressurized of its air volume is big more; therefore protect effect also just better; therefore; in limited space; increase the diameter of air chamber; will improve the compressive capacity of air-packing device; but since the carton that requires packing material of traffic cost can not infinitely amplify require the smaller the better; because the space is limited; in order to improve the compressive capacity of some significant points, increase the full diameter of the air chamber at these positions, the full diameter of the air chamber at other positions of corresponding minimizing.Another main purpose that increases local air chamber diameter is in order to reduce packaging volume.Increase buffering at main position, thereby but reduce the air chamber diameter at the positions that do not need a lot of protections and can reduce volume effectively and reduce the freight.If the air chamber size is the same, volume is just very big.

Wherein, the sealed air chamber that full diameter is bigger is equipped with two or more check valves.

Because the air chamber diameter is big more; the load-carrying capacity of its pressurized is big more, and the protection effect will be better, therefore; in limited space; increase the diameter of air chamber, will improve the compressive capacity of air-packing device, but the air chamber diameter becomes big; its inflationtime increases relatively; will influence the work required time, therefore two or more check valves are installed in a larger-diameter air chamber, solve the problem of inflationtime.Simultaneously, fold is big more many more because air chamber brings the more or less freely generation fold of the functional self-adhering structure of internal layer (check valve) more greatly, and the probability of air seepage from these fold is just high more.So strengthening the surface adhesion force of check valve and planeness by the mode that multi-channel is set at air chamber and increases reinforced rib in the part solves and increases the gas leakage problem that gas column brought.

Wherein, preferably, the big or small air chamber of described packing device is alternately distributed.

After this structure inflation is finished, atmospheric air chamber and little air chamber, form wavy, have only the major diameter air chamber to contact with the object of inner packing, as the fluting board packing, so when article fell, the acceleration due to gravity split-up that is produced by weight of object was to different three-dimensionals, thereby reduce the power of vertical direction.Simultaneously, the major diameter air chamber plays once to cushion acceleration due to gravity is slowed down, thereby the compression of major diameter air chamber contacts little air chamber jointly, and the less air chamber of diameter this moment plays the effect of secondary buffer.Therefore, use the buffering effect of this structure to be better than the contact surface on the basic plane that identical air chamber forms.

Wherein, preferably, described packing device is rectangular bag of an end opening.

Like this, during the packing object, need to use two packing devices, be enclosed within the both sides of object, like this,, just can use as long as a rectangular pack object has the size of a side to be fit to packing device.The range of use broad.

Wherein, preferably, described packing device is the bag shape.

Bag shape packing device is applicable to the packing object that packing requirements is higher relatively, makes each face of packaged object all be subjected to good protection.

Wherein, preferably, the full diameter of a plurality of air chambers of described packing device both sides is less, and middle air chamber full diameter is bigger.

Wherein, preferably, adopt thermoplastic envelope sealing check valve on the check valve of the air chamber that one or more full diameters of both sides are less, close the free air diffuser of this air chamber.

Like this, only need on the basis of original product, increase the thermoplastic closing step of the little air chamber on one side pressure air chamber side, just can obtain the packing device of the packing object of another kind of dimensions, need not die sinking tool again, saved productive costs greatly, and can adjust the operation on the manufacturing line as required at any time, satisfy actual needs, reduce tank farm stock.

Wherein, described packing device secondary plastic packaging forms the side pressure air chamber.

Thereby can lower transport space and the too high problem of cost solution packing long-distance transportation cost greatly by the method for using on-the-spot straight forming the user.Utilize soft-plastic material and make product smooth fully before not using by prefabricated design, utilize when the user uses air make this material fast, stereo shaping and around need protection product, form fail-safe structure.Compared with prior art, air-isolated packing material of the present utility model has anti-extruding, anti-vibration, anti-falling fallen and good integrated protection performance such as buffering, can be used as the filling wrapper of article, the omnibearing external packing of the part of article or the partiting pad of significant points and article is used.
