Abstract
The utility model discloses an extraction-free vacuum bag, which comprises a bag body with an opening and a one-way exhaust valve. The one-way exhaust valve replaces an extraction valve on a conventional vacuum bag, air in the bag can be exhausted via the one-way vacuum exhaust valve by pressing the bag body of the vacuum bag externally, and vacuum compression package of the vacuum bag can be realized when the one-way exhaust valve is sealed after air is exhausted completely. The extraction-free vacuum bag is simple and reasonable in structure and can be widely used for vacuum package for articles.
Description
Technical field
The utility model relates to a kind of vacuum bag, particularly a kind of vacuum bag of bleeding of exempting from.
Background technology
When article are packed preservation, often to use vacuum compression bag, be called for short vacuum bag.The principle of general vacuum bag, be on common plastic packaging bag, to install an extraction valve additional, article to be preserved after the opening of bag body is put into bag, are shut sack, and the air extracting pump with peripheral hardware connects with extraction valve then, utilize air extracting pump that the air in the vacuum bag is taken away, because air reduces in the vacuum bag, the barometric pressure of outside just flattens sack, pastes clothes fully with article to be packaged, Deng an air in the bag drained clean after, take air extracting pump away and seal up valve rapidly.But traditional vacuum bag must be equipped with the air extracting pump of peripheral hardware, and this makes and bothers very much when carrying out vacuum packaging and inconvenience.
The utility model content
The purpose of this utility model is for a kind of vacuum bag of bleeding of exempting from is provided, and it has and need not to be equipped with air extracting pump and can easily air in the bag be drained the vacuum-packed characteristics of carrying out.
The solution that the utility model solves its technical matters is:
A kind of vacuum bag of bleeding of exempting from comprises the bag body that is provided with opening, and described bag also is provided with at least one one-way exhaust valve on one's body.
Be further used as preferred embodiment, described one-way exhaust valve comprises: valve body, and its upper end is opened wide, and the lower end has several induction openings, and the inwall below is provided with step, and described step top is provided with flange; Facial mask, the surface, any place that it belongs to bag body is coated on the upper end open of described valve body, has several air gates above; Resilient spacer, it is positioned at the inner chamber of described valve body, closely cooperates with flange, and described step stretches out and stops that resilient spacer can not drop it, allows resilient spacer can block induction opening fully.
Be further used as preferred embodiment, described resilient spacer be shaped as the plane plate that entad shrinks both sides.
Be further used as preferred embodiment, described valve body, resilient spacer are the elastoplast member.
The beneficial effects of the utility model are: the utility model makes the extraction valve on traditional vacuum bag into one-way exhaust valve, the feasible bag body that only need externally push vacuum bag, air in the bag can be discharged from one-way exhaust valve, Deng sealing one-way exhaust valve after the air emptying, can realize the vacuum compression packing of vacuum bag.The utility model is simple and reasonable, is widely used in the vacuum packaging of article.
In addition, the utility model can also be used for because of being exposed to the package storage of materials such as the oxidized easily medicine of air, vitamin, micro-element; Be used for producing and discharging a small amount of gas and do not influence the package storage of the material of its internal memory quality at storage process; Being used for part has the material of special odor or fragrance, as probiotics, bioengineering fermented product, spices, essence package storage, so neither influence the sense organ of people to its smell or fragrance, help material again and directly be not exposed in the air.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is an integral structure scheme drawing of the present utility model;
Fig. 2 is the birds-eye view of one-way exhaust valve of the present utility model;
Fig. 3 is the transverse sectional view of Fig. 2, and wherein resilient spacer is in and the close-fitting state of flange;
Fig. 4 is the transverse sectional view of Fig. 2, and wherein resilient spacer is in the state that separates with flange, and arrow is represented the flow direction of air.
The specific embodiment
With reference to Fig. 1, a kind of vacuum bag of bleeding of exempting from comprises the bag body 2 that is provided with opening, also is provided with at least one one-way exhaust valve 1 on the described bag body 2.
With reference to Fig. 2～Fig. 4, be further used as preferred embodiment, described one-way exhaust valve comprises: valve body 11, its upper end is opened wide, and the lower end has several induction openings 12, and the inwall below is provided with step 17, and described step 17 tops are provided with flange 16; Facial mask 21, the surface, any place that it belongs to bag body 2 is coated on the upper end open of described valve body 11, has several air gates 22 above; Resilient spacer 13, it is positioned at the inner chamber of described valve body 11, closely cooperates with flange 16, and described step 17 stretches out and stops that resilient spacer 13 can not drop it, allows resilient spacer 13 can block induction opening 12 fully.
Be further used as preferred embodiment, described resilient spacer 13 be shaped as the plane plate that entad shrinks both sides.
Be further used as preferred embodiment, described valve body 11, resilient spacer 13 are the elastoplast member.
During work, earlier article to be packaged are put into vacuum bag from the opening of bag body 2, with pressure-sealing zipper or heat-sealing equipment sack is shut then, then push bag body 2 outside, bag body 2 in-to-in air are expressed to the lower cavity 14 of valve body 11 from induction opening 12; Because the effect of extruding, air pressure in the lower cavity 14 is with resilient spacer 13 jack-up upwards, itself and flange 16 broken away from and fall into the upper cavity 15 of valve body 11, air just from the space of the both sides that the gap between resilient spacer 13 and the upper cavity 15 and resilient spacer 13 entad shrink itself, is discharged in the atmosphere along air gate 22 in the bag; After bag body 2 internal gas are got rid of totally, push facial mask 21 outside downwards, resilient spacer 13 is closely cooperated with flange 16 again, realize the sealing of one-way exhaust valve 1, and facial mask 21 makes the action of vacuum bag outside be difficult to influence resilient spacer 13, makes it break away from flange gas leakage.
More than be that preferable enforcement of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
