Description

Liquid package bag with self-sealed mouth

The utility model relates to a kind of can and carries the sealing film pack for liquids of liquid.

As everyone knows, liquid product adopts flexible packaging to sell class to see not bright in the market.For example: flexible packing products such as soy sauce, yellow rice wine, beverage have been striden to huge numbers of families, and some big cities with some promptly irritate promptly drink or in a short time the bright goods (as: soya-bean milk, cow's milk etc.) of drink (making) usefulness also adopted flexible packaging in a large number, be that liquid product is sold in flexible packaging, be very easy to consumers in general, firmly get society's favor.But in use also there is defective in the packaging bag of existing flexible packaging: 1. the customer must destroy packaging bag earlier in drink (making) time spent, could take out liquid.And after opening the package, liquid must once be used up in the bag, or commentaries on classics is loaded on other container; 2. if will utilize the original packing bag temporarily to deposit surplus liquid, or new clothes liquid is when sealing, must be by sealing tool, otherwise deposit or carry with regard to inconvenience, make the customer feel inconvenience very much.

Task of the present utility model provides the self-sealing thin film fluid packaging bag of a kind of energy, and with this fluid bag packaged products, do not destroy packaging bag and just can take out liquid, to surplus liquid or new clothes liquid automatic sealing once more, and can repeated use; This product has easy to use, and the life-span is long, the characteristics that productive costs is low.

Task of the present utility model is realized by following technical proposals:

Sealing part at existing plastic film packaging bag, insert two small pieces films envelope and press the sack tube that forms the hollow two open ends, sack tube and packaging bag are connected as a single entity on the sealing line of packaging bag, and a sack tube part stretches into the packaging bag inner chamber, and a part is in packaging bag inner chamber outside.During the producer can, liquid pours into packaging bag from the sack tube, irritated liquid after, because of the liquid that remains on the sack tube barrel film forms gravitation and surface tension, two films are close to; Add the hydraulic pressure in the packaging bag bag, the sack tube is closed, watertight, reach self-sealing purpose.

The utility model compared with prior art only set up a sack tube in existing packaging bag, so structure is very simple.When the customer uses, can draw or pour out as long as insert suction pipe from the sack tube, extract out pinch behind the suction pipe packing sack shake several down just can automatic sealing, watertight, and reusable, preserve and the sack tube can be sealed up with capper as the need long period, it is very easy to operate.Moreover carry boiling water, self-control beverage when going out, go into the street buy in bulk other to beat liquid product etc. also very convenient.

Be described further by embodiment below in conjunction with accompanying drawing:

Accompanying drawing is the utility model example structure scheme drawing.

See accompanying drawing, on the opening part of thin film fluid packaging bag 1, be inserted with sack tube 2, sack tube 2 is connected as a single entity on sealing line 3 with fluid bag 1.A sack tube part stretches into the fluid bag inner chamber, and a part is in fluid bag inner chamber outside, and the degree of depth A that wherein stretches into fluid bag 1 inner chamber is greater than 20 millimeters, and the width B of sack tube 2 and packaging bag 1 inner chamber joint portion is less than 50 millimeters.The sack barrel shape that stretches into the fluid bag inner chamber can be random, and exterior sack barrel shape of inner chamber and size also can be random.

Production method: the plastic sheeting fluid bag of selected required shape and size, it is stand-by to stay an open-ended; Get 80 millimeters of two lengths of a film, wide 30 millimeters plastic sheeting is close to the back and is sealed into the sack tube of hollow two open ends with capper.Then, insert the scraps of paper in the sack tube, its purpose is to prevent fluid bag and the timing of sack wound packages, and sack tube passage is shut; The sack tube that will insert the scraps of paper more inserts in the fluid bag, seals pressure together with capper, take out the scraps of paper product.
