Abstract
The utility model discloses an exhaust structure of wrapping bag, this wrapping bag is including the portion of accomodating and locate the exhaust portion of accomodating the portion bottom, and the open -top department of the portion of accomodating is equipped with the sealing strip, and bottom one side of the portion of accomodating is equipped with gas vent, this gas vent intercommunication exhaust portion, exhaust portion is equipped with one in one side bottom of this gas vent on the contrary and feeds through to the outside gas outlet of wrapping bag, and the both sides interval is provided with a plurality of arc convex parts about the inner wall of this exhaust portion. Because the setting of a plurality of arc convex parts through arc convex part production resistance, under the effect that no hand was pressed, can't directly get into to the gas vent when making the outside air desire to get into to the gas vent by the gas outlet, can guarantee the compression state in the portion of accomodating. Compare in current wrapping bag, the utility model discloses owing to set up a plurality of arc convex parts, therefore its exhaust is effectual to simple structure, the outward appearance is pleasing to the eye.
Description
Technical field
This utility model is related to a kind of packaging bag, particularly relates to a kind of exhaust structure of packaging bag.
Background technology
Existing bag for containing clothes typically in the air bleeding valve of the one side setting pumping of collecting bag, is extracted by air pump
Air in collecting bag after sealing, makes medicated clothing compress, thus reducing taking up room of medicated clothing as far as possible.But the receipts of this structure
Bag of receiving needs just to extract the air in collecting bag by air pump, and structure is complex, once air pump damages or loses,
This collecting bag just cannot be carried out aerofluxuss, and its air bleeding valve of the collecting bag of this structure is the side table being installed in prominent collecting bag
Face, can cause collecting bag surface irregularity, and easily be coughed up by air bleeding valve, structure and in appearance equal existing defects.
Therefore, for improving the deficiency of above-mentioned collecting bag, separately there is a kind of packaging bag, as shown in figure 1, being by packaging bag 10 ' point
Be divided into accommodation space 11 ' and exhaust space 12 ', exhaust space 12 ' located at the bottom of accommodation space 11 ', this accommodation space 11 '
Bottom side is provided with an air vent 111 ', and this air vent 111 ' connects this accommodation space 11 ', and this exhaust space 12 ' is away from aerofluxuss
The side of mouth 111 ' is provided with a gas outlet 121 ', when being intended to accommodation space 11 ' is exhausted, by the top of this packaging bag 10 '
Toward exhaust space direction volume, so that the air in accommodation space 11 ' is flow in exhaust space 12 ' by air vent 111 ', and pass through
Gas outlet 121 ' is discharged.But, due to the air vent 111 ' of this accommodation space 11 ' and the gas outlet 121 ' of this exhaust space 12 '
Form a beeline channel, outside air enters in exhaust space 12 ' easily by this gas outlet 121 ', then by air vent
11 ' entrance accommodation spaces 11 ', make the air of accommodation space 11 ' cannot drain, there is the not good defect of exhaust effect.
In view of this, the design people is directed to and does not attain perfect led to many disappearances in above-mentioned packaging bag exhaust structure design
And inconvenience, and deeply conceive, and positive research improvement has a fling at and develops and design this utility model.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, good exhaust effect, and specious packaging bag
Exhaust structure.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of exhaust structure of packaging bag, this packaging bag includes incorporating section and the exhaust portion located at incorporating section bottom, storage
The top open part in portion is provided with sealing strip, and the bottom side of incorporating section is provided with air vent, and this air vent connects described exhaust portion, institute
State exhaust portion and be provided with one in contrast to a side bottom of this air vent and be communicated to gas outlet outside packaging bag, the inwall of this exhaust portion
Both sides are arranged at intervals with multiple arcs protuberance up and down.
The highest of the peak of arc protuberance on the upside of exhaust portion and the adjacent arc protuberance located at exhaust portion bottom
The distance of point sum >=this exhaust portion upper and lower sides.
Directly heat-sealing takes shape in this exhaust portion described each arc protuberance.
After said structure, the exhaust structure of this utility model packaging bag be set up in the exhaust portion of this packaging bag many
Individual arc protuberance, so that during this packaging bag aerofluxus, gas can be discharged from air vent and is whirled up through arc protuberance, through hand
Pressing gradually drains into gas outlet, therefore, after this utility model aerofluxuss are complete, after outside air enters exhaust portion, due to multiple
The setting of arc protuberance, makes extraneous air be entered to by oral erotism of giving vent to anger and produces resistance through arc protuberance during air vent, in no handss
It is impossible to be directly entered to air vent the compressive state it is ensured that in incorporating section in the presence of portion's pressing.Compared to existing packaging
Bag, due to arranging multiple arcs protuberance, therefore its good exhaust effect, and structure is simple, specious for this utility model.
Brief description
Fig. 1 is the structural representation of existing packaging bag.
Fig. 2 is the structural representation of this utility model packaging bag.
Specific embodiment
In order to the technical solution of the utility model is explained further, this utility model is entered below by specific embodiment
Row elaborates.
As shown in Fig. 2 this utility model discloses a kind of exhaust structure of packaging bag, this packaging bag 100 includes incorporating section 1
And the exhaust portion 2 located at incorporating section 1 bottom, the top open part of this incorporating section 1 is provided with sealing strip 11, the bottom one of incorporating section 1
Side is provided with air vent 12, and this air vent 12 connects described exhaust portion 2, and described exhaust portion 2 sets in contrast to the bottom of this air vent 12
There is the gas outlet 21 outside a connection packaging bag 100, the upper and lower both sides of inwall of this exhaust portion 2 are arranged at intervals with multiple arcs protuberance
22, each arc protuberance 22 directly seals and takes shape in this exhaust portion 2, and wherein, the arc protuberance 22 located at exhaust portion 2 upside is
Peak d2 sum >=this exhaust portion 2 upper and lower sides of high point d1 and the adjacent arc protuberance 22 located at exhaust portion 2 bottom are apart from l.
During use, article are loaded in incorporating section 1 by the opening of incorporating section 1, and sealing strip 11 is tamping, hand can be passed through
Air in incorporating section 1 is directly pushed toward air vent 12 direction by pressing from opening, or this incorporating section 1 is rolled by opening,
And toward air vent 12 direction volume, make the air in incorporating section 1 automatically drain into exhaust portion 2 from top toward bottom direction, due to aerofluxuss
Multiple arcs protuberance 22 is set up, so that during this packaging bag 100 aerofluxus, gas can be discharged through arc from air vent 12 in portion 2
It is whirled up during protuberance 22, gradually drain into gas outlet 21 through hand pressing, therefore, after this utility model aerofluxuss are complete, outside
After air enters exhaust portion, due to the setting of multiple arcs protuberance 22, make extraneous air by gas outlet 21 air vent to be entered to
When 12 through arc protuberance 22 produce resistance, no hand pressing in the presence of it is impossible to be directly entered to air vent 12 it is ensured that
Compressive state in incorporating section 1.Compared to existing packaging bag, this utility model due to arranging multiple arcs protuberance 22, therefore its
Good exhaust effect, and structure is simple, specious.
Above-described embodiment and schema non-limiting product form of the present utility model and style, any art
Suitable change or modification that those of ordinary skill is done to it, all should be regarded as without departing from patent category of the present utility model.
