Abstract
The utility model discloses a vacuum apparatus for a plastic package bag, and belongs to food and article packaging bag structures. The vacuum apparatus for the plastic package bag is characterized in that the plastic package bag with a through hole provided in the middle of a plastic single face of the plastic package bag is provided, a valve pedestal is provided on the through hole in the middle of the plastic single face, the other end of the valve pedestal is provided with an upper cover matched with the valve pedestal, a spring is provided in the upper cover, and a front end of the spring is a rubber valve arranged in the valve pedestal and matched with the valve pedestal. In the working process of the vacuum apparatus, when the air in the plastic package bag is pumped out, the rubber valve tightly presses a bottom plane in a circular groove of the valve pedestal under the action of the spring and the air pressure outside the bag, so that the air outside the bag is prevented from entering the bag again. The vacuum apparatus for the plastic package bag not only has a compact structure, but also is convenient and practical, and can achieve the effect that the plastic package bag is in a vacuum state for a long time.
Description
Technical field
The utility model relates to the structure of food and bag for packaging materials, specifically a kind of vacuum of plastic packaging bag.
Background technology
The plastic packaging bag of existing environment-protecting asepsis is widely used in food and article packing, but owing to tend to have air in the packaging bag, make that article are moist, food guarantee the quality and freshness date has received influence.Though have the people to design the vacuum of plastic packaging bag at present; But because of not designing spring, inlet scoop, therefore when rubber valve is closed, there is not spring moment to push down; Be easy to let air be back to once more in the plastic packaging bag, reduced the plastic packaging bag vacuum effectiveness.
Summary of the invention
In order to overcome the deficiency of existing product; The purpose of the utility model is that the device an of the utility model is installed in the appropriate location of plastic packaging bag edge; This device can remove the air extraction of plastic packaging bag; Can stop air to get in the bag once more again, thereby can make plastic packaging bag keep vacuum state, improve the vacuum of article moisture proof and food preserving and a kind of later-model plastic packaging bag that acts on such as fresh-keeping.
The utility model solves the technical scheme that its technical matters adopted: a kind of vacuum of plastic packaging bag; It is characterized in that: the middle plastic packaging bag that offers through hole of a plastics single face is arranged; Plastics single face intermediate throughholes is provided with valve base; The other end of valve base is provided with the loam cake that is mated, and is provided with spring in the loam cake, and the front end of spring is to be arranged on the rubber valve that is mated in the valve base.
Be provided with the cylinder of a convexity in the middle of being shaped as of described valve base, cylinder cylindrical stage casing is provided with protruding semicircle circle; The cylinder inboard is provided with protruding post, and its effect is when rubber valve is installed, and can make rubber valve and cylinder inboard maintain the space and does not slide; Recessed circular groove is provided with pore a little less than the recessed circular groove in this plane to be provided with one in the middle of the inboard baseplane of cylinder, and its effect is when rubber valve is closed, and can let the rubber valve pressed downward, and sealing more is close to; Be provided with air-breathing groove entad below the valve base, its effect is to be convenient to air emptying in the plastic packaging bag.
The inboard stage casing of described loam cake is provided with groove, is used for during installation having with centre above the valve base that the protruding semicircle circle in stage casing blocks on the protruding cylinder.The cylinder that it is the fixing spring of through hole that the inner centre of loam cake is provided with a centre is provided with the rank slotted eye on the cylinder, claim the inlet scoop.The effect of slotted eye is when the air of plastic packaging bag is drawn out of, and rubber valve is drawn onto on the column cap, and air can be discharged outside the bag through slotted eye above the cylinder from the pore of recessed circular groove.
The utility model places in valve base and put into stainless steel spring on rubber valve, the rubber valve, aim at cylinder outer rim above the valve base to loam cake at last packs into and compresses.In a plastic packaging bag hole offering, the appropriate location of corner of one side wherein.Hole size is identical with this device, then this device is placed in this preset hole of plastic packaging bag, makes it bonding with the hot-pressing processing method at last.
The beneficial effect of the utility model is: since the utility model work in after the air of plastic packaging bag is drawn out of; Outside spring and bag under the effect of air pressure; Rubber valve is pushed down the baseplane in the valve base circular groove tightly, has stoped the entering once more of bag outer air.Therefore not only structure is tight for the utility model, and convenient and practical, can reach the effect that keeps plastic packaging bag to belong to vacuum for a long time.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structure cutaway view of the utility model.
Fig. 2 is that the valve base of the utility model amplifies three-dimensional view.
Fig. 3 is that the loam cake of the utility model amplifies three-dimensional view.
Among the figure: 1 plastic packaging bag, 2 valve bases, 3 loam cakes, 4 springs, 5 rubber valves.
The specific embodiment
Embodiment 1:
A rectangular plastic packaging bag 1 is arranged; An edge of plastics single face offers a through hole; Through hole is provided with valve base 2; The other end of valve base 2 is provided with the loam cake 3 that is mated, and is provided with spring 4 in the loam cake 3, and the front end of spring 4 is to be arranged on the rubber valve 5 that is mated in the valve base 2.
