Abstract
The utility model discloses a kind of packaging bags with lamination valve port, including bag body, the upper and lower ends of the bag body are respectively arranged with bottom and bottom, the bottom is equipped with perfusion valve port, and the perfusion valve port is connected to the inside of bag body, and the perfusion valve port includes the valve body of tubular, the valve body includes built-in portion and epitaxy part, the built-in portion is arranged in bag body, and the epitaxy part stretching bag is external, and the inner wall of the epitaxy part includes the leaching membrane layer of annular.The utility model in overhanging valve port by increasing leaching membrane layer so that after completion is filling, melts leaching membrane layer by the hot body of peripheral hardware and closes, play good sealing effect.
Description
Technical field
The utility model is related to a kind of packaging bags, especially valve-port packaging bag.
Background technology
In the existing packaging bag with valve port, it mainly is sticking bag by what paper, modeling and composite paper-plastic material were made, as
Filling passageway and seal means, valve port are generally divided into interior valve port and outer valve port.And in existing outer valve port, generally existing sealing
The undesirable situation of effect.Powder after filling, is easy to spill from valve port.
Utility model content
The technical problems to be solved in the utility model is：A kind of more strict peripheral hardware valve-port packaging bag of sealing is provided.
The solution that the utility model solves its technical problem is：A kind of packaging bag with lamination valve port, including bag body,
The upper and lower ends of the bag body are respectively arranged with bottom and bottom, and the bottom is equipped with perfusion valve port, the perfusion valve port and bag
The inside of body is connected to, and the perfusion valve port includes the valve body of tubular, and the valve body includes built-in portion and epitaxy part, the built-in portion
It is arranged in bag body, the epitaxy part stretching bag is external, and the inner wall of the epitaxy part includes the leaching membrane layer of annular.
As a further improvement of the above technical scheme, the width of the leaching membrane layer is equal to or more than the length of epitaxy part.
As a further improvement of the above technical scheme, the valve body includes at least two layers of layers of kraft paper.
As a further improvement of the above technical scheme, include the paper film of tubular between the layers of kraft paper, it is described
Paper film extends to the inner wall of bag body.
The utility model has the beneficial effects that：The utility model in overhanging valve port by increasing leaching membrane layer so that
After completion is filling, leaching membrane layer is melted by the hot body of peripheral hardware and is closed, good sealing effect is played.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.In addition, all connection/connection relations being previously mentioned in text, not singly refer to component and directly connect, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each technology in the invention is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
Referring to Fig.1, the upper and lower ends of a kind of packaging bag with lamination valve port, including bag body 1, the bag body are respectively arranged with
Upper bottom and bottom 11, the bottom 11 are equipped with perfusion valve port 2, and the perfusion valve port is connected to the inside of bag body, the pouring valve
Mouth 2 includes the valve body of tubular, and the valve body includes built-in portion and epitaxy part 21, and the built-in portion is arranged in bag body, described outer
Prolong portion and stretch out that bag is external, the inner wall of the epitaxy part includes the leaching membrane layer 3 of annular.It is close in existing overhanging valve-port packaging bag
Envelope still relies primarily on paper film in valve port, sealing effect is not satisfactory, and used instead the utility model with leaching membrane layer
After valve port, sealing effect is more preferably.
It is further used as preferred embodiment, the width of the leaching membrane layer is equal to or more than the length of epitaxy part.Heat-sealing
When, leaching membrane layer has been covered with the epitaxy part of valve body, further increases sealing effect.
It is further used as preferred embodiment, the valve body includes at least two layers of layers of kraft paper.Utilize two layers of ox-hide
Paper can improve the intensity of valve body, avoid the case where valve port ruptures when filling.
It is further used as preferred embodiment, includes the paper film of tubular, the paper between the layers of kraft paper
Film extends to the inner wall of bag body.
The better embodiment of the utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
