Abstract
The utility model relates to a compound plastic aluminum bag dedicated unidirectional air outlet valve, comprising valve seat, valve plate and valve cover. Valve seat and packing pocket are closely heat sealed or adhere together. Valve cover and valve seat closely fit. Between valve cover and valve seat is valve cavity where valve plate is set. There are vents on both valve cover and valve seat. Its advantage lies in that it can discharge remain air in plastic packing pocket through unidirectional exhaust valve, improve stacking stability, increase stacking height, raise anti-impact ability of plastic packing pocket, reduce shock wave caused by remain air in plastic packing pocket when carrying and beating, reduce or avoid broken bag; at the same time, unidirectional exhaust valve can also avoid outside air entering the bag.
Description
Technical field
The utility model relates to a kind of one-way exhaust valve, especially a kind of one-way exhaust valve that is used for plastic packaging bag.
Background technique
Plastic packaging bag is widely used in all trades and professions, Aluminum-plastic composite bag (hereinafter to be referred as aluminium plastic bag) is a kind of novel package bag (national New Product catalog number 06030211) of development in recent years, belong to a kind of special plastic packaging bag, have protection against the tide, lucifuge, shielding, antistatic, good packaging characters such as barrier is high, long shelf-life, be used for the packaging of meat products of food industry at first, capacity is very little.Along with the continuous development and the innovation of science and technology, all trades and professions are more and more higher to the requirement of packing, and aluminium plastic bag has been extended to fields such as chemical industry, medicine, precision type instrument, high pure metal, electronic parts and components and national defence highly sophisticated products from food industry.Therefore market is maximization, multipurpose, high quality, high-performance to the requirement of aluminium plastic bag.
The aluminium plastic bag that is used for chemical industry, its capacity be generally 25kg or more than.Require one to be moistureproof, long shelf-life; The 2nd, shock resistance guarantees to reach in transit not bale broken at packaging process; The 3rd, in order to save the place, it is high that stacking is wanted.Through discovering that one of major reason that influence shelf-life, shock resistance and stacking height is: in packaging process, want entrained air inevitably, packing finishes seal after, this part air just remains in the bag.The south air is moist, and the aqueous vapor that remains in the bag is one of adverse factor that influences the shelf-life; Package bag is when falling, and the air that remains in the bag can produce very big shock wave, causes bale broken; The air that remains in simultaneously in the bag is unsettled when stacking, and therefore the bag type can not keep smooth and steady state, thereby influences stacking height.
Summary of the invention
The purpose of this utility model is: at present plastic packaging bag, especially the air of remaining part moisture content influences the shelf-life easily in the Aluminum-plastic composite bag, the air that remains in the bag makes bag stacking instability, when package bag is fallen from eminence, air in the bag also can produce very big shock wave, the practical problem that causes bale broken provides a kind of one-way exhaust valve that is used for plastic packaging bag.
The purpose of this utility model is achieved in that a kind of Aluminum-plastic composite bag special single-way outlet valve, comprise valve seat (2), valve block (3) and valve gap (4), it is characterized in that: closely heat seal or be bonded together of valve seat (2) and package bag (1), valve gap (4) closely cooperates with valve seat (2), form valve pocket between valve gap (4) and the valve seat (2), valve block (3) places the valve pocket between valve gap (4) and the valve seat (2), is equipped with vent on valve gap (4) and the valve seat (2).
In the utility model: valve block (3) can adopt rubber or plastic production.
Advantage of the present utility model is: owing to be provided with one-way exhaust valve on plastic packaging bag, the package bag of filling goods is in the process of stacking, be under the action of gravity of the residual air goods in the package bag of top in the bag of bottom and discharge from one-way exhaust valve, can improve the stable stability of stacking, increase stacking height; Improved the impact resistance of plastic packaging bag, when the package bag of filling goods in carrying or when eminence is fallen, the air in the bag can be discharged from one-way exhaust valve, reduces the shock wave of the interior residual air generation of bag, reduces or avoids consequent bale broken; Simultaneously, one-way exhaust valve can also avoid ambient air not enter in the bag.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, plastic packaging bag; 2, valve seat; 3, valve block 4, valve gap.
Embodiment
Accompanying drawing discloses a kind of concrete structure of model utility embodiment without limitation, below in conjunction with accompanying drawing model utility is done to describe further.
As seen from Figure 1: model utility comprises valve seat 2, valve block 3 and valve gap 4, wherein: valve seat 2 is with plastic packaging bag 1 tight heat seal or be bonded together, valve gap 4 closely cooperates with valve seat 2, form valve pocket between valve gap 4 and the valve seat 2, valve block 3 places the valve pocket between valve gap 4 and the valve seat 2, be equipped with vent on valve gap 4 and the valve seat 2, valve block 3 can adopt rubber or plastic production.In the present embodiment, valve block 3 adopts rubber to make.
During concrete enforcement, valve seat 2 should be arranged on the bag face of plastic packaging bag 1, when stacking, should make one-way exhaust valve place the upper surface of the plastic packaging bag of filling goods.
Claims (2)
1, a kind of Aluminum-plastic composite bag special single-way outlet valve, comprise valve seat (2), valve block (3) and valve gap (4), it is characterized in that: closely heat seal or be bonded together of valve seat (2) and package bag (1), valve gap (4) closely cooperates with valve seat (2), form valve pocket between valve gap (4) and the valve seat (2), valve block (3) places the valve pocket between valve gap (4) and the valve seat (2), is equipped with vent on valve gap (4) and the valve seat (2).
2, Aluminum-plastic composite bag special single-way outlet valve according to claim 1 is characterized in that: valve block (3) adopts rubber or plastic production.
