Description
Technical Field
The invention relates to the field of packaging devices, in particular to a film fluid container, a stop valve and a manufacturing method thereof.
Background
With the change of modern life style and the rapid development of logistics industry, many articles are traded in logistics form, such as electronic products, chemical products, medical products, ceramics, glass and other daily necessities, and during the storage or transportation of the articles, the articles are inevitably extruded, collided, dropped and the like, so that the articles are damaged or deformed, and serious loss is brought to people.
The buffer material is applied to the field of gas packaging materials, achieves the buffer effect by filling gas, has the advantages of low cost and easy storage compared with the traditional packaging materials, has better buffer efficiency, and is beneficial to environmental protection. The conventional gas packaging bag is generally formed by bending a gas column to form a plurality of gas side walls, and each gas side wall is surrounded to form an internal accommodating space for storing and packaging articles, such as a common U-shaped bag, C-shaped bag or O-shaped bag. The liquid container is applied to the field of liquid packaging materials, and has the advantages of low cost, convenient transportation, great saving of storage space and the like compared with the traditional liquid container by injecting liquid (including a refrigerant).
In the prior art, a continuous sealing body comprises two outer membranes and two inner membranes, wherein heat-resistant materials are coated on the top ends of the inner surfaces of the two inner membranes at equal intervals to form a plurality of heat-resistant joints, heat-seal opening points and heat-seal transverse lines are applied to the equal heights of the outer membranes and the heat-resistant joints to divide the sealing body into an air inflation channel region and an air storage cylinder, the air inflation channel is in upper and lower butt joint with the air storage cylinder through the heat-seal lines, and the heat-seal lines are applied to the equal heights of the outer membranes and the heat-resistant joints to form a channel air inlet between the air inflation channel and the; and an inflation inlet connected with the air inlets of the channels, so that when the inflation inlet is inflated, the outer membrane is expanded at the air channel part to pull the connected inner membrane away, and all the air inlets along the air channel are inflated indirectly and completely.
In the prior art, for example, referring to the position of the opening point of patent document CN200610067311.5, the position of the heat seal point is below the vertex of the heat-resistant node, and is not at the vertex. During inflation, the part of the air valve membrane above the heat seal point will stick together and not be easily opened. When the inflation is carried out, the two air valve films can be attached to the outer film on one side because the air valve films cannot be opened, and air cannot enter the air inlet and cannot enter the air inlet, so that the inflation effect is influenced. Or after the air is inflated into the main cavity, because of the air pressure, and based on the effect of the heat sealing point, the two inner membranes are opened to inflate, but the two inner valve membranes at the part above the heat sealing point are also inwards sunken due to the viscosity problem and the air pressure problem, so that the possibility of air inlets is blocked, and the inflation effect and the inflation efficiency are influenced.
In the prior art, for example, refer to patent no open point patent of patent document CN201010162908.4 for the problem of the length of the two inner membranes. If the two inner membrane parts are arranged to be short, when the manufacturing process applies a heat sealing line, the two inner valve membranes are too short, the inner valve membranes are completely heat-sealed on the heat sealing line, and the convex valve membranes above the heat sealing line are not generated, so that the inflation effect is influenced. If the valve membrane is excessively arranged in the two outer membranes, the two outer membranes can be attached together in the process of inflation due to the viscosity problem, and the valve membrane is extruded to one side of the two outer membranes due to air pressure and is not easy to open. When the inflation is carried out, the two air valve films can be attached to the outer film on one side because the air valve films cannot be opened, and air cannot enter the air inlet and cannot enter the air inlet, so that the inflation effect is influenced. Or the two inner membranes are opened, the two inner membranes are also sunken, and the air inlet is blocked due to the inward sunken air pressure problem, so that the air inflation effect and the air inflation efficiency are influenced. And no matter how long two interior valve membranes are, can lead to two inner membranes to stretch out the partial length that the heat-seal line was above all to be greater than the longitudinal width of admitting air mouth because of the structure of inwards converging of main channel heat-seal line (length is fixed, and is unanimous with the gas column width), so can lead to two inner membranes to cave in, still can inwards cave in because of the atmospheric pressure problem, then block the admission mouth, influence inflation effect and efficiency.
In the air inlet inner membrane in the prior art, the two valve membranes are not fully opened or can not smoothly intake air in the air inflation process, so that the air inflation column can not be inflated to intake air, and the air inflation column cannot be used. A structural treatment at the valve membrane is required.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Fig. 1 to 4 show a stop valve for an adhesive film fluid container according to a preferred embodiment of the present invention. The stop valve for the glue film fluid container can be fully opened and smoothly fed with fluid during the process of injecting the fluid. In the embodiment of the present invention, the fluid may be implemented as a gas, or may be implemented as a liquid such as water or other fluid.
As shown in fig. 1 to 4, the stop valve 20 for an adhesive film fluid container includes a first valve film 21 and a second valve film 22, and the stop valve 20 for an adhesive film fluid container can be used for an adhesive film fluid container. The adhesive film fluid container comprises at least two layers of first container films 11 and second container films 12, and the adhesive film fluid container is formed into the container comprising one or more fluid storage units 13 which are connected in parallel through a series of plastic packaging lines, and a fluid storage chamber 14 capable of storing fluid is formed in each fluid storage unit 13. The first and second valve films 21 and 22 of the shut-off valve 20 for an adhesive film fluid container and the first and second container films 11 and 12 are disposed to overlap each other, and an injection fluid passage 23 for injecting fluid into the fluid storage chamber 14 is formed between the first and second valve films 21 and 22. It will be appreciated that the first and second valve membranes 21, 22 are shorter in length than the first and second container membranes 11, 12. When the fluid storage chamber 14 is filled with fluid through the injection fluid channel 23 and the fluid pressure in the fluid storage chamber 14 reaches a predetermined requirement, the fluid pressure in the fluid storage chamber 14 acts on the first valve film 21 and the second valve film 22 to make the first valve film 21 and the second valve film 22 tightly fit to one of the container films, thereby closing the fluid passage and then blocking the injection fluid channel 23, so that the stop valve 20 for the adhesive film fluid container functions as a one-way valve. When at least one fluid inlet channel 23 is formed in each fluid storage unit 13 and the fluid storage units 13 are independent of each other, when one of the fluid storage units 13 is damaged and leaks fluid, the other fluid storage units 13 are not affected and can play a fluid buffering effect.
It is understood that the first and second container films 11 and 12 of the adhesive film fluid container and the first and second valve films 21 and 22 of the shut-off valve 20 for the adhesive film fluid container may be made of various suitable film materials, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, polystyrene film, or composite film, etc., and the present invention is not limited in this respect as long as it is a suitable flexible film. It is worth mentioning that, in order to increase the one-way sealing effect, the first valve film 21 and the second valve film 22 of the stop valve 20 for the adhesive film fluid container may be self-adhesive films obtained by modifying the above films by adding chemical components.
The adhesive film fluid container further includes a main channel unit 15 connected to each of the fluid storage units 13, preferably, integrally extended from each of the fluid storage units 13. More specifically, in one embodiment, the main passage unit 15 is perpendicular to the extending direction of the fluid storage unit 13. For example, in one embodiment, each of the fluid storage units 13 extends in a longitudinal direction, and the main passage unit 15 extends in a transverse direction. The main passage unit 15 forms a main passage 151, and the main passage 151 has a fluid-filling port 152, when the fluid-filling port 152 is positioned with a fluid-filling nozzle and performs a fluid-filling operation, fluid enters the main passage 151 from the fluid-filling port 152 in a lateral direction and then enters each of the fluid storage units 13 in a longitudinal direction, and when a predetermined fluid pressure is reached in each of the fluid storage chambers 14, the first and second valve films 21 and 22 of the shut-off valve 20 for a film fluid container are attached to one of the fluid chamber films 11 or 12, thereby achieving self-closure to prevent the re-reverse-permeation of the injected fluid into the main passage 151.
It is understood that the main passage unit 15 may be formed of two layers of the first and second container films 11 and 12, two layers of the first and second valve films 21 and 22, one layer of the first or second container film 11 or 12 and one layer of the first or second valve film 21 or 22, or two layers of the first and second container films 11 and 12 and two layers of the first and second valve films 21 and 22.
The planar plastic sealing line of the adhesive film fluid container further includes a continuously sealed edge sealing line 32 respectively located at both sides of the top and bottom and a continuously sealed main channel sealing line 33 located at the top side, wherein the main channel 151 is formed between the edge sealing line 32 at the top side and the main channel sealing line 33 at the top side. It will be appreciated that the edge sealing line 32 is formed by a plastic molding process such as bonding or heat sealing and seals the two container films 11 and 12, and the main passage sealing line 33 is formed by a plastic molding process such as bonding or heat sealing and seals the two container films 11 and 12 and the two first and second valve films 21 and 22 together.
The planar plastic sealing line further includes a set of flow guide lines 34, the first and second valve films 21 and 22 and the first container film 11 are heat-sealed along the flow guide lines 34, and the flow guide lines 34 are disposed at both ends of the injection fluid channel 23 and connected to the main channel sealing line 33 to guide an injection direction of the fluid when the fluid is injected.
Each of the fluid storage units 13 is heat-sealed to the first container film 11 at a position adjacent to the main channel 151 by a plurality of connecting lines 35, so that when a predetermined fluid pressure is reached in the fluid storage chamber 14, the fluid pressure acts on the first and second valve films 21 and 22 and is simultaneously pressed against the fluid chamber film 11 and finally against the first container film 11 due to the provision of the connecting lines 34 and 35, thereby closing the fluid passage and thus blocking the injection fluid channel 23. That is, the joining lines 34 and 35 heat-seal join two layers of the first and second valve films 21 and 22 and one layer of the fluid chamber film 11. The shape of each of the connection lines 34 and 35 is designed such that it further functions to prevent backflow of fluid, that is, when the fluid in the fluid storage chamber 14 is intended to flow back, it is blocked by the connection lines 34 and 35 and cannot easily reverse-permeate into the main channel 151. In addition, in heat-sealing these planar plastic sealing lines, the injection fluid passage 23 of the valve films 21 and 22 of the shut-off valve 20 for an adhesive film fluid container may be formed by providing a heat-resistant blocking means, which is taken out after the heat-sealing process.
A heat-resistant layer 24, which may be heat-resistant ink for example, is disposed between the first valve film 21 and the second valve film 22 of the shut-off valve 20 for an adhesive film fluid container, and is communicated with the main passage 151 without closing its inlet by heat-sealing. The main passage 151 is formed by two layers of the container films 11 and 12, and the heat-resistant layer 24 and the first and second valve films 21 and 22 each have an extension into the main passage 151.
The shut-off valve 20 also includes a positioning marker block 2433, the positioning marker block 2433 being provided to determine the position of the main passage seal line 33 and the connecting lines 34 and 35. The positioning mark block 2433 is next to the first valve film 21 or the second valve film 22.
In this preferred embodiment of the invention, as shown in fig. 2, the positioning mark block 2433 is rectangular in shape, and the positioning mark block 2433 has a pair of main channel seal line parallel sides 2433b and a pair of main channel seal line vertical sides 2433a, the main channel seal line parallel sides 2433b being parallel to the main channel seal line 33, and the main channel seal line vertical sides 2433a intersecting and perpendicular to the main channel seal line 33. Wherein the main channel seal line parallel side 2433B has a side length value of B, the main channel seal line vertical side 2433a has a side length value of C, and the main channel seal line 33 is spaced from the main channel seal line parallel side 2433B at the outer tip of the positioning mark block 2433 by a distance value of a. Wherein over a range of values, defined as B: a is not less than pi. The reason for this is that if the injection fluid is in the process that the first valve film 21 and the second valve film 22 are not opened, the first valve film 21 and the second valve film 22 are recessed inward to leave a certain gap so that the fluid can be injected into the injection fluid port. It is therefore necessary that half of the circumference with a radius is longer than a, i.e. defining B: a is not less than pi. That is, before injecting the fluid, the length B of the main passage seal line parallel side 2433B of the positioning mark block 2433 is set in advance, and then by defining B: and A is not less than pi, and the numerical range of A is determined, so that the position range of the main channel sealing line 33 is determined.
Specifically, during the process of filling the adhesive film fluid container with the fluid, the first valve film 21 and the second valve film 22 are opened as the fluid enters, even if the first valve film 21 and the second valve film 22 are recessed inwards due to the fluid pressure or other reasons, so that the first valve film 21 and the second valve film 22 are not completely attached to the fluid chamber film 11 and the fluid chamber film 12. That is, during the process that the first valve film 21 and the second valve film 22 are not opened, the first valve film 21 and the second valve film 22 are recessed inward but have a certain gap so that the fluid fills the fluid inlet. As shown in fig. 4, the maximum degree of inward depression of the first valve film 21 and the second valve film 22 may affect the effect and efficiency of fluid injection if the degree of inward depression is larger than the maximum degree. As can be seen in fig. 4, in this preferred embodiment, the length of the perimeter with a as a radius is twice the length of B. If a certain gap is left between the first valve film 21 and the second valve film 22, it is necessary that the length of B is greater than half the length of the circumference with a radius, i.e., 2A × pi ÷ 2 ═ a pi in value. That is, the length of B is greater than A π, i.e., B: a is not less than pi. By limiting such a numerical ratio, even if the first valve film 21 and the second valve film 22 are depressed downward at the time of injecting the fluid, there is a certain gap for the fluid to enter the injection fluid port 23.
Preferably, in other variant embodiments, when in value A is 3mm, B ≧ 3 π, A is optimally 3mm, the optimal interval is 3mm ± 2mm, and B should be in the range B ≧ 5 π.
It is worth mentioning that in the modified embodiment, the heat-resistant layer 24 is provided with the positioning mark block 2433. In other modified embodiments, the positioning mark block 2433 may not be disposed on the heat-resistant layer 24. For example, in a modified embodiment, the positioning mark block 2433 is implemented as the heat-resistant layer 24. For another example, in a modified embodiment, the positioning mark block 2433 is implemented as a coating block. For another example, in a variant embodiment, the alignment mark pieces 2433 are implemented as other substances followed by a heat resistant layer or coating piece. Also for example, the positioning mark block 2433 is implemented to be directly printed on the first valve membrane 21 or the second valve membrane 22 or the fluid chamber membrane 11 or 12.
It is worth mentioning that in order to facilitate the first valve film 21 and the second valve film 22 to be opened for injecting the fluid more easily, the viscosity between the two layers of the first valve film 21 and the second valve film 22 is smaller than the viscosity between the first valve film 21 and the first container film 11 or the viscosity between the second valve film 22 and the second container film 12. Specifically, during the process of filling the adhesive film fluid container with the fluid, the viscosity between the two layers of the first valve film 21 and the second valve film 22 is smaller than the viscosity between the first valve film 21 and the first container film 11 and the viscosity between the second valve film 22 and the second container film 12. The first valve film 21 and the second valve film 22 are easily opened without the first valve film 21 and the second valve film 22 being attached together or attached close to the first container film 11 or the second container film 12 side during the fluid filling process, thereby not affecting the fluid filling effect thereof.
Further, in a preferred embodiment, the surfaces of the first valve film 21 and the second valve film 22 and the equal-length portions of the positioning mark blocks are roughened so that the viscosity of the portions of the first valve film 21 and the second valve film 22 is less than the viscosity between the first valve film 21 and the first container film 11 and less than the viscosity between the second valve film 22 and the second container film 12. Thereby making it easier for the first valve membrane 21 and the second valve membrane 22 to be opened. Preferably, one or both of erucamide and oleamide are used when roughening treatment is performed. Erucamide is an important derivative of erucic acid, and is an excellent fine chemical product with wide application range. It is mainly used as anti-sticking agent and slip agent for various plastics and resins, excellent lubricant and antistatic agent for extruded film, because of its higher melting point and good thermal stability (stability at 273 deg.C). Oleic acid amide (called Oleamide) in English, cis-9-octadecenamide (cis-9-octadienoamide) belongs to unsaturated fatty amide, is a white crystalline or granular solid, has a polycrystalline structure and is odorless, and can reduce friction between an internal friction film and conveying equipment in a processing process of resin and the like, simplify operation of a final product and further increase production. For example, the resin can be used as a lubricant in polyethylene processing, and the melt viscosity of resin particle forming can be reduced, and the fluidity can be improved. One or both of erucamide and oleamide are continuously coated or cover-coated between the first valve film 21 and the second valve film 22 or on either one of them by the length of the equal position mark block (heat-resistant coating block), which can reduce the tackiness between the first valve film 21 and the second valve film 22 and improve the smoothness.
It is worth mentioning that in a variant embodiment, it is preferable that said first valve membrane 21 and said second valve membrane 22 are provided with a roughening treatment, preferably equal in value to the length of said main channel sealing line vertical edge 2433a of said positioning mark block 2433, and not too long, so as not to affect the overall closing performance of the valve membranes, but at least equal to or greater than a.
