Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As depicted in figs. 1 and 2, integrated film flexible package fluid injection charge valve, including the first film 1 and the second film 2, the
The material and size all same of one film 1 and the second film 2, is generally made of thermoplastic, the first film 1 and
Two films 2 fit together and form the gap passage 3 of a Z-type or S types.The first film 1 and the second film 2 are generally by pre-
The sizing envelope mould first manufactured, is bonded to form an entirety using the modes such as hot pressing or high frequency or ultrasonic wave, makes first in fitting
The gap passage 3 of Z-type or S types that one penetrates through is left between film 1 and the second film 2.Integrated film flexible package fluid injection is filled
Air valve can coordinate the films flexible package such as packaging bag to be used together, by the direct hot-melt adhesive paste of valve body in packaging bag.
Integrated film flexible package fluid injection charge valve can also be applied to integrated film flexible package product, as shown in figure 3,
The first film 1 and the second film 2 are downwardly extending a closed inner cavity 7, and the inner cavity 7 is connected to internal channel 6, real
Existing integrated molding production, it is possible to reduce production waste saves production cost, improves production efficiency.Gap passage 3 is mainly used for
Fluid injection or inflation inside to the films such as packaging bag flexible package product.
The gap passage 3 includes the outer tunnel 4, transverse passage-way 5 and the internal channel 6 that are sequentially connected, and the transverse passage-way 5 is located at the
The width range at the middle part of one film 1 and the second film 2, the outer tunnel 4 is 10-40mm, and the width of transverse passage-way 5 is less than 10mm
And length is more than 50mm, the width of internal channel 6 is less than or equal to the width of transverse passage-way 5.The size of outer tunnel 4 is larger, is mainly used for
It is connected with external fluid injection or air charging system, the liquid or gas of injection pass through outer tunnel 4, transverse passage-way 5, internal channel successively
Enter in the films flexible package products such as packaging bag after 6, the size of internal channel 6 is smaller, in the films flexible package product such as packaging bag
It is swollen after fluid injection or inflation to rise and then make valve body stress deformation and reach self sealss, it has been enter into the films flexible package product such as packaging bag
Liquid or gas can not flow back.
For the ease of to fluid injection or inflation in the films flexible package product such as packaging bag, the outer tunnel 4 is connect with transverse passage-way 5
Locate arc-shaped, internal channel 6 and 5 junction of transverse passage-way are arc-shaped.In order to enhance the self sealss of valve body, the outer tunnel 4 and interior
The width in channel 6 is gradually reduced each along the direction of 4 inward channel 6 of outer tunnel, i.e., the arrival end of outer tunnel 4 to outer tunnel 4 with
The connected one end width of transverse passage-way 5 is gradually reduced, the width for 6 outlet end of one end inward channel that internal channel 6 is connected with transverse passage-way 5
It is gradually reduced.One end that transverse passage-way 5 is connected with outer tunnel 4 is gradually reduced to the width of the other end, and transverse passage-way 5 is close to outer tunnel 4
One end extend to the edge of the first film 1 and the second film 2, can increase gas or the resistance of liquid reflux, increase
The self sealss of valve body.
The operation principle of the utility model is as follows：Integrated film flexible package fluid injection charge valve can be directly anchored to pack
On the films flexible packing products such as bag, integrated film flexible package fluid injection charge valve can also be applied to integrated film flexible package system
Product, the first film 1 and the second film 2 are downwardly extending a closed inner cavity 7, and the inner cavity 7 connects with internal channel 6
It is logical.When needing to inject liquid into integrated film flexible package product or be filled with gas, need outer tunnel 4 and outside
Fluid injection or air charging system are connected, then carry out fluid injection or inflation.In integrated film flexible package product it is hydraulically full or
After gas, the inner cavity 7 of integrated film flexible package product can expand.The first film 1 and the second film 2 all have certain stretching
Property, since internal channel 6 is connected to inner cavity 7,6 bottom of internal channel also can be by a larger tensile stress, and 6 top of internal channel is several
It will not be stretched stress, and very small for the size of the size opposite bores 7 of internal channel 6, internal channel 6 is caused to stretch
Fitting is generated under the action of stress, and internal channel 6 is made to realize self sealss.Meanwhile liquid is full of in integrated film flexible package product
After body or gas, the expansion of inner cavity 7 makes the first film 1 and the second film 2 generate certain deformation, in order to keep integrated film soft
Packing articles entirety stress balance, integrated film flexible package product meeting natural distortion fold, since transverse passage-way 5 is located at first
The middle part of film 1 and the second film 2, transverse passage-way 5 can be due to distorting, folding realization self sealss.
Certainly, the utility model can also have other various embodiments, real without departing substantially from the spirit of the present invention and its principle
In the case of matter, those skilled in the art can make various corresponding change and deformations, but this according to the utility model
A little corresponding change and deformations should all belong to the protection domain of the utility model the attached claims.
