Abstract
The utility model relates to a packing bag, in particular to an air pressure self-support packing bag. The packing bag comprises a main body 1 and an edging confinement area 2, which is characterized in that a U-shaped channel11 is provided on the main body1, the U-shaped channel 11 can be arranged on the right upper or the left upper of the main body, the flow ratio of the air pressure self-support packing bag can control be controlled according to the demands of people. The air pressure inside the bag is smaller than the atmosphere pressure, which will not make the liquid flow out when the packing bag leans or falls on the ground.
Description
Technical field
The utility model relates to packaging bag, specifically, relates to a kind of air pressure self-support packaging bag.
Background technology
Existing pack for liquids, adopt common sealing means mostly, during use, cut off an osculum at packaging bag end one jiao, be difficult to its flow of control when liquid is poured out, after the use, remaining liq in the bag is easy to because the cause flow such as inclination of packaging bag are come out, cause waste, bring very big inconvenience therefore for people's use, can't satisfy people's needs.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of air pressure self-support packaging bag, in use can control its flow according to people's needs, and use the back pkt. internal gas pressure less than barometric pressure, liquid that can not is because the inclination of packaging bag or fall down to the ground etc. former thereby flow out.
Technical matters of the present utility model realizes by following scheme: construct a kind of air pressure self-support packaging bag, described packaging bag comprises the seal area at main body and edge thereof, it is characterized in that, described main body is provided with the U-shaped passage.
A kind of air pressure self-support packaging bag according to the utility model provides is characterized in that described U-shaped passage can be arranged on the upper right corner of main body.
A kind of air pressure self-support packaging bag according to the utility model provides is characterized in that described U-shaped passage can be arranged on the upper left corner of main body.
A kind of air pressure self-support packaging bag according to the utility model provides is characterized in that the right and left of described seal area is provided with protuberance.
A kind of air pressure self-support packaging bag according to the utility model provides is characterized in that described protuberance can be circular arc.
A kind of air pressure self-support packaging bag according to the utility model provides is characterized in that described protuberance can be rectangle.
Air pressure self-support packaging bag of the present utility model has following advantage: the U-shaped passage is set, can controls the flow of bag interior liquid when pouring out liquid in the use; After the use because the bag internal gas pressure is less than the barometric pressure of outside, therefore in the bag remaining liquid that can not because the inclination of packaging bag or fall down to the ground and flow out.
Description of drawings
Fig. 1 is the utility model air pressure self-support packaging bag without using and the port front view under the unsealing state still.
Specific embodiment
Structural representation is as shown in Figure 1 constructed a kind of band air pressure self-support packaging bag, and described packaging bag comprises the seal area 2 at main body 1 and edge thereof, it is characterized in that, described main body 1 is provided with U-shaped passage 11; Described U-shaped passage 11 can be arranged on the upper right corner or the upper left corner of main body 1; The right and left of described seal area 2 is provided with protuberance 21,22; Described protuberance 21,22 can be circular arc, also can be rectangle.
During use, an end that is provided with the U-shaped passage in packaging bag is cut off the U-shaped passage with scissors, squeezes with hand then, the liquid in the bag can be extruded along the U-shaped passage.
