Detailed description of the invention
Referring to figs. 1 through Figure 14, the packaging bag of a kind of no leakage body, comprise the first film 1, the second film 2, the 3rd film 3 and the 4th film 4, the length of described the first film 1 and the 4th film 4 is greater than the length of described the second film 2 and the 3rd film 3, described the second film 2, the 3rd film 3 is between described the first film 1 and the 4th film 4, the inwall welding of described the 3rd film 3 and described the 4th film 4, local welding between described the second film 2 and the 3rd film 3, between the second film 2 and the 3rd film 3, form feed pathway 5, if the second film 2, the width of the 3rd film 3 is less than the width of the first film 1 the 4th film 4, the edge of described the first film 1 and described the 4th film 4 weldings form bag, if the first film 1, the second film 2, the 3rd film 3 is identical with the width of the 4th film 4, the edge of described the first film 1 and described the second film 2, the local edge welding of the 3rd film 3 and the 4th film 4 forms bag.
For the packaging bag that does not set out water pipe, in the time drinking, packaging bag can be torn to an osculum, in the present invention, described the first film is provided with outlet pipe that can be automatically closed, feed pathway 5 also can be positioned at outlet pipe, and in the time of water suction, feed pathway 5 can not be opened. Can syndeton be set at outlet pipe top, as arranged and the middle cover of existing feeding bottle, the connector that nipple mates, can directly be connected on middle cover and nipple and form feeding bottle. For the suction pipe with automatic closing function, in prior art, there is numerous embodiments to realize, the present invention provides following four kinds of concrete structures.
The first structure is referring to Fig. 4, Fig. 5, the sidewall of described outlet pipe 6 is provided with bending impression 7, described in when nature, outlet pipe 6 is along the 7 position nature bendings of bending impression, block the passage in described outlet pipe 6, make in application, upwards lift the end of suction pipe, the passage in outlet pipe 6 is opened, and just can be out of the water.
The second structure is referring to Fig. 8, Fig. 9, described outlet pipe 6 comprises hypomere outlet pipe 60 and epimere outlet pipe 61, the lower end of described hypomere outlet pipe 60 is connected with described the first film 1, upper end is connected with the lower end of described epimere outlet pipe 61 by a resilient sleeve 8, the upper end end face of described hypomere outlet pipe 60 is provided with the first apopore 601, the lower surface of described epimere outlet pipe 61 is provided with the second apopore 610, when nature, be subject to the pulling force effect of resilient sleeve 8, the upper surface laminating of described epimere outlet pipe 61 lower surfaces and described hypomere outlet pipe 60 forms sealing, described the first apopore 601 and the second apopore 610 are not communicated with, in order to strengthen waterproof effect, the upper surface of described hypomere outlet pipe 60 is provided with sealing-plug 602 corresponding to the position of described the second apopore 610, when nature, described sealing-plug 602 is filled in described the second apopore 610 and is formed and seal, in use, the end of the section of pressing outlet pipe 61 downwards, epimere outlet pipe 61 lower surfaces separate with the upper surface of described hypomere outlet pipe 60, just can be out of the water, after drinking, epimere outlet pipe 61 is replied under the effect of resilient sleeve 8, self-assembling formation sealing.
The third structure is referring to Fig. 6, Fig. 7, and the end of described outlet pipe 6 is provided with water outlet designated port 12, and in the time sucking, water outlet designated port 12 is opened, and forms liquid outlet channel, and when nature, the sealing of water outlet designated port elastic reaction, prevents that liquid from spilling.
The 4th kind of structure is referring to Figure 10, Figure 11, one end that described outlet pipe 6 is positioned at described bag is provided with sealing valve 10, in described outlet pipe 6, be provided with the rib 11 being connected with described sealing valve 10, in the time drinking, lip squeezes out the end of water pipe 6, rib 11 inside contracts, push sealing valve 10 open and form liquid outlet channel, when nature, rib 11 elastic reactions restore naturally, the inwall that sealing valve 10 is close to packaging bag forms hermetically-sealed construction, prevents that liquid from spilling.
Because packaging bag is vacuum there is no filling front inside, after filled drink, packaging bag is propped up, there is certain hardness, in the time drinking, the suction of mouth is equivalent to vacuumize, along with the minimizing of liquid in bag, beverage bag bottom is from bottom to top taken out flat, make beverage all the time at the topmost of beverage bag, do not need to come back and just can suck, when sucking, guarantee can not be drawn onto air, no matter the beverage in beverage bag is also surplus how many after drinking, certain glutted as long as there being the packaging bag at beverage position just to have, when hand-held, there is all the time certain hardness, solve on present market the shortcoming that cannot hold steadily because of soft couch when beverage bag is hand-held.
Referring to Figure 12,13, in described bag, be provided with along its length curling 9 of the elasticity of arranging, curling 9 of elasticity can be as shown in figure 12 one, can be also as shown in figure 13 two etc., curling 9 of elasticity is harder elastoplast or steel wire, after filling liquid, packaging bag is supportted directly, in drinking process, along with the minimizing of liquid in bag, packaging bag is curling under the effect of curling 9 of elasticity, forms structure as shown in figure 14, convenient liquid in bag has been drunk.
Packaging bag of the present invention makes pouring into liquid, and hydraulic pressure forces feed pathway 5 to be opened, after tubulose, hydraulic pressure in bag seals the second film 2, the 3rd film 3, and liquid can not flow out, and can dispense the sealing work in later stage, the qualification rate that can improve product, reduces production costs.
