Abstract
The utility model provides an air resisting valve for a packaging bag. A proper point on the packaging bag is provided with a plurality of air outlet holes; an air resisting valve is fixedly attached to the inner side face of the packaging bag and is corresponding to the point of the air outlet holes; the air resisting valve is composed of a valve seat and a diaphragm, wherein, the valve seat is provided with a containing chamber; the bottom face of the containing chamber is provided with a plurality of air holes, a plurality of stop blocks are arranged above the containing chamber, and the diaphragm is contained in the containing chamber of the valve seat; the bag opening of the packaging bag is sealed, the packaging bag is extruded so that the air in the bag pushes the diaphragm up through the air holes of the air resisting valve and gets out via the air outlet holes of the packaging bag, and the air in the packaging bag can be discharged so that the air in the bag is reduced to form a pressure difference with the outside of the bag to cause the diaphragm to be adsorbed to cover and be attached to the air holes so as to prevent the air and the moisture from entering the packaging bag.
Description
Technical field
The utility model relates to the choke valve of packaging bag, refer in particular in the applying of packaging bag medial surface appropriate location and set firmly a choke valve, and packaging bag is provided with several air gates, the corresponding air gate of choke valve position, as long as choke valve is made of a valve seat and a diaphragm, so the push-through packs bag, make bag interior air discharge the interior air of bag by choke valve, the interior air of bag reduces and forms difference of pressure outward with bag again, makes the diaphragm adsorption cover be attached to the pore of choke valve, enters in the packaging bag to prevent air and moisture.
Background technology
Press,, generally suppress the bacterial growth,, also avoid one of mode that food becomes damp and rotten if air, moisture can be isolated except that freezing, cold storage mode because people are more and more higher to the fresh-keeping requirement of article; No matter whether right traditional packaging bag be vacuum-packed, the structure that does not have any involution again when packaging bag once Kaifeng, be provided with crack at sack at the most, for temporary transient sealing sack, make the interior article of bag avoid dropping out and to prevent that maybe cockroach or other insects from entering a bag internal contamination food, but owing to still have a large amount of air in the bag, therefore the article (as food, tealeaves etc.) in the bag still become damp and rotten easily;
Edge this, I in view of this, studied, designed, at first create the utility model.
Summary of the invention
Main purpose of the present utility model, be to provide a kind of can be with air exhaustion in the bag, and prevent that effectively air, moisture from entering the choke valve of the packaging bag in the bag.
The utility model is achieved through the following technical solutions: a kind of choke valve of packaging bag, mainly comprise packaging bag, and it is characterized in that: fitting at packaging bag medial surface appropriate location is installed with a choke valve; Wherein the packaging bag appropriate position is provided with several air gates, and choke valve is fixedly arranged on packaging bag and aligns the air gate position; This choke valve comprises a valve seat and a diaphragm, and wherein valve seat is provided with room, and the room bottom surface is provided with several pores, and is provided with several blocks above the room, and diaphragm is placed in the room of valve seat; Air in the bag can be scurried out through the air gate of packaging bag pushing away on the diaphragm by the pore of choke valve again, and forms difference of pressure outward with bag, and diaphragm then adsorbed to paste and covered on pore this moment.Wherein:
Valve seat one side of described choke valve is provided with amplexiforms edge, fits in the medial surface of packaging bag and engages with the packaging bag hot melt.
The utlity model has the following advantage:
1. choke valve integral body of the present utility model is flats, fits in the packaging bag to fix through hot melt, and forms one with packaging bag, and do not take up space, do not influence the capacity that packaging bag can supply splendid attire.
2. choke valve of the present utility model makes the air only export but no import, so behind the air exhaustion in the bag, because of the inside and outside different difference of pressure of packaging bag, make this diaphragm be adsorbed lid and be affixed on the pore of room bottom surface, uses preventing that packaging bag air and moisture from entering in the packaging bag.
Description of drawings
Fig. 1, be three-dimensional exploded view of the present utility model.
Fig. 2, be the choke valve group in the packaging bag inboard, the schematic appearance during the clamp sack.
Fig. 3, when discharging air in the packaging bag action scheme drawing of its diaphragm of choke valve.
Fig. 4, for the diaphragm of choke valve is adsorbed on the pore, prevent the scheme drawing of air admission packaging bag.
The specific embodiment
The utility model is to reach above-mentioned application target and effect, and the technological means that is adopted is enumerated preferable feasible embodiment now, and cooperates graphicly, and details are as follows:
Consult Fig. 1, a kind of choke valve of packaging bag is mainly fitted at packaging bag 1 medial surface appropriate location and is set firmly a choke valve 2; Wherein sack 10 is established in packaging bag 1 upper end, the appropriate position of packaging bag is provided with several air gates 11, and including the diaphragm 21 that a valve seat 20 and a rubber material make, choke valve 2 constitutes, wherein valve seat 20 is provided with room 200, room 200 bottom surfaces are provided with several pores 201, and be provided with several blocks 202 above the room 200, and diaphragm 21 is placed in the room 200 of valve seat 20, and a side of valve seat 20 is established and is amplexiformed edge 203.
Consult Fig. 1-3, during assembling, at first the diaphragm 21 of choke valve 2 is placed in the room 200 of valve seat 20, again with amplexiform the inner face that edge 203 fit in packaging bag 1 of choke valve 2 with valve seat 20, and align with air gate 11 positions, impose hot melt and engage, can make choke valve 2 be fixed in location in the packaging bag 1.
Consult Fig. 2-4, when using operation, behind packaging bag 1 Kaifeng, or after article are put into packaging bag 1, can sack 10 binders of packaging bag 1 be tightened, as long as push-through packs bag 1 with the hands by sealing clip 3, air in the packaging bag 1 just can be entered by the pore 201 of choke valve 2 bottom surfaces, diaphragm 21 is upwards pushed open, and the air in the bag is then scurried out through the air gate 11 of packaging bag 1, can discharge the air in the bag; Moreover, owing to behind the air exhaustion in the bag,, make this diaphragm 21 be adsorbed lid and be affixed on the pore 201 of room 200 bottom surfaces, enter in the packaging bag 1 to prevent packaging bag 1 air and moisture because of packaging bag 1 inside and outside different difference of pressure.
In sum, the utility model can reach desired purpose really and use effect, and does not see more that in like product that the same structure feature is arranged is known, formerly public, so meet the application important document of novel patent, files an application in accordance with the law.
