Description

Vacuum compression bag

Technical field

The utility model relates to a kind of vacuum compression bag.

Background technology

Vacuum compression bag mainly utilizes the mode that vacuumizes, with air extraction in the bag, so that article compression in the bag is reduced storage volume, so vacuum extractor design-calculated quality is just very important on the vacuum bag.

As the patent No. is that the Chinese utility model " vacuum compression storage bag " (notification number CN2296325Y) of ZL97211564.1 has designed a kind of vacuum compression storage bag, the through hole that connects in its storage bag is sealing automatically, rapidly storage bag and outside air are isolated, can reach the purpose that vacuum is preserved.But this patent need realize the automatic sealing of through hole, structure relative complex by an elastic element after sucking air.And for example the patent No. is the Chinese utility model " the vacuum compression storage bag with air-breathing and closing device " (notification number CN2284748Y) of ZL97200989.2, aspirator system in this patent is by an independently patch realization through hole sealing, though it is relatively simple for structure, but can't seal automatically, sealing effectiveness is not good, and when the loam cake of aspirator system was turned on fully, this independent patch was lost easily, was not easy to the partition of aspirator system and assembling again.

Therefore, in view of the foregoing, await the aspirator system of vacuum compression bag is further improved.

Summary of the invention

Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of simple in structure, vacuumize effectively, and seal permanent failure-free vacuum compression bag.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this vacuum compression bag includes

One bag of body has a peristome and the circular hole that is positioned at side surface;

One closing device is arranged on the peristome of bag body; And

One aspirator system, be arranged on the described circular hole, described aspirator system includes interconnective base and valve seat, and base has the through hole that connects of circular hole with the bag body in the bottom surface, valve seat offers in the bottom surface and the cooresponding open-work of through hole, also is distributed with some aspirating holes around the open-work;

It is characterized in that: described valve seat wears a spool moving up and down at through-hole position, described spool has the valve head and the seal strip of the open-work upper and lower end face that can recline respectively, under the vacuum seal state, described seal strip is sealed the opening of through hole and is offseted with the base plate through holes end face.

For conveniently using and sealing, described closing device can be the self-styled slide fastener of guide groove sliver structure with a pair of concavo-convex cooperation, this self-styled slide fastener can directly be mediated with hand and seal, and also can along the slippage of slide fastener direction sliver be embedded in the guide groove automatically with a chuck.

Useful is, described valve seat bottom surface can be the wheel set shape, then radially uniformly at intervals around described open-work, the valve seat bottom surface also can be other shape to described aspirating hole, and aspirating hole also can non-ly be arranged in around the described open-work in uniform way and can hold gas communication and get final product.

As further improvement, described valve seat bottom has is with externally threaded flange, described base has the suitable groove of a tapped and described flange, valve seat and base are mutually permanently connected, this thread connecting mode is not unique, also can be that described valve seat bottom has a tapped groove, and described base have with the suitable flange of externally threaded and described groove, can realize captiveing joint of valve seat and base equally.

Described aspirator system also include one with the suitable end cap of valve seat, this end cap can prevent that dust from falling in the valve seat opening, and can play certain sealing function.

In order to strengthen the connection compactness between valve seat and the base, can also be provided with clamping piece between described base and the valve seat.

Compared with prior art, advantage of the present utility model is to have worn a spool moving up and down at the through-hole position of valve seat, this spool has the valve head and the seal strip of the upper and lower end face of open-work that can recline respectively, and open-work also is distributed with some aspirating holes on every side, when air-breathing, utilize and be threaded and valve seat and base can be outwarded winding, leave certain space between the two, seal strip can be with the suction of gas upwards and touch the open-work lower surface, and air is just through through hole very fast extraction of quilt from aspirating hole of base; Waiting to bleed finishes, take away aspirate tube after, screw valve seat, just make seal strip downwards compress owing in the bag negative pressure is arranged this moment, avoids the air admission extracted out, the article that so just can make compression in the bag are preserved for a long time and air tight, very convenient practicality.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Be depicted as a preferred embodiment of the present utility model as Fig. 1 to 6,

The vacuum compression bag of present embodiment, include bag body 1 with a peristome 11, bag body 1 usefulness PA, PE or PET, PE film composite material are made, the self-styled slide fastener 2 of the guide groove sliver structure of a pair of concavo-convex cooperation is arranged on described peristome 11 as the closing device of bag body 1, this self-styled slide fastener 2 has a chuck 3, and chuck 3 can embed the sliver of self-styled slide fastener 2 to cooperate in the guide groove along the slippage of slide fastener direction and clamp.

Also have circular hole 12, one aspirator systems 4 in the side of bag body 1 and be arranged on the circular hole 12, described aspirator system 4 includes base 41 and the valve seat 42 that is threaded mutually, and is arranged on the clamping piece 43 between base 41 and the valve seat 42;

Wherein, base 41 has the through hole 411 that connects of circular hole 12 with bag body 1 in the bottom surface, and base 41 tops have a tapped groove 412;

Valve seat 42 bottom surfaces are the wheel set shape, and its bottom surface offers and described through hole 411 corresponding open-works 421, and some aspirating holes 422 are radially uniformly at intervals around open-work 421; Described valve seat 42 also is equipped with a spool 44 moving up and down at open-work 421 places, this spool 44 adopts nonrigid plastic, and have the valve head 441 and the seal strip 442 that are connected as a single entity, can abut in open-work 421 upper and lower end faces respectively, valve seat 42 bottoms have with the suitable flange 423 of the groove on the externally threaded and described base 41 412; Valve seat 42 and base 41 interconnect fixing by internal and external threads.

Described aspirator system 4 also include one with the suitable end cap 45 of valve seat 42, can prevent that dust from entering valve and doing, can also play sealing function.

The working process of this vacuum compression bag is: being threaded between base 41 and the valve seat 42 outwarded winding, make between valve seat 42 and the base 41 and have certain space, it is air-breathing to aim at valve seat 42 open-works 421 with air-breathing instruments such as domestic vacuum cleaners, spool 44 is upwards picked up, simultaneously, seal strip 442 can be with the suction of gas upwards and touch open-work 421 lower surfaces, and air is just through through hole 411 very fast extraction of quilt from the aspirating hole 422 of valve seat 42 of base 41 (in referring to Fig. 3 shown in the arrow); Wait to bleed and finish, after taking away aspirate tube, screw thread fit between valve seat 42 and the base 41 is tightened, this moment is owing to have negative pressure in the bag, seal strip 442 is compressed and aligned through holes 411 is sealed it downwards, can avoid the air admission compressed bag of extracting out, play vacuum-packed effect (referring to Fig. 4).At last, can be with end cap 45 glands in valve seat 42 upper ends, further enhanced leaktightness and dustproof effect.
