Description

A kind of bag body of the bag in box with guiding gutter

Technical field

The utility model belongs to packaging facilities field, and in particular to a kind of bag body of the bag in box with guiding gutter.

Background technology

Bag in box, it is a kind of high-capacity packaging form for being used for containing solid and liquid (3L-1000L), the packaging is by one Individual easily flexible bag body is formed in outside rigid packet.In fact, internal bag body is combined by two sacks： Inner bag is used for containing liquid, and outer bag takes blocking effect.The edge of inner bag and outer bag is enclosed in together by thermoplastic encapsulation technique, separately Outside, in the process of bag body, a mouth of pipe is had by thermoplastic envelope to inner bag and outer bag, matched also has a use Carry out function valve that is filling and taking food.Generally when the non-sterile property of progress is filling, bag in box bottle placer unplugs valve first, Vacuumize process is carried out to sack, then filling food again, then presses upper valve again, complete it is filling after serves conveyer belt. For the filling of aseptic, then the operation that at least two steps are extra is needed.Before filling, entered using chlorine dioxide line up position Row sterilization；Again in pressure valve terminate it is filling before, then to sack filling with inert gas with discharge partial air.In addition, In sterile filling, tap is by vapours around bag body is then needed by gamma-ray irradiation in itself.

In the U.S., most often the product of this system of application includes wine, dairy products (ice cream, milk shake) and the water of one gallon of dress Fruit product (fruit juice, pulp, fruit, jam) etc..The market graduation of bag in box is that 20% consumer applies the mechanism with 80% Or large delivery application.In India, in addition to above-mentioned field, edible oil, lubricating oil and hot filling beverage concentrate or fruit juice etc. are also Field with very big application potential.In addition, bag in box can be used for making up a prescription for hospital, such as cough syrup, functional beverage Deng.

Bag in box the U.S. broad development, it is closely related with the compatible development for selling system.For example, using bag in box bag The Postmix beverage syrup market of dress, a wide range of popularization with laughable, Pepsi the automatic vending machine of cola are undivided.Typical case Automatic vending machine by drink syrup from bag in box release, it is mixed with quantitative chilled carbonated water.In India, those are applicable In the development of Postmix beverage syrup and the automatic vending machine of fruit juice, it will accelerate the use of bag in box compatible system.For wine Packaging be a breakthrough for bag in box, present bag in box extended the packaging for being applied to other various products, such as Edible oil, fruit juice (hot filling and sterile filling), sherry, fruit wine, milk and more viscous fluid product, such as tomato Sauce, vinegar (hot filling to 2L packaging bags), thick broad-bean sauce etc..Bag in box is not limited to smaller retail packaging, and nowadays scope has covered 10L consumer's packaging, 10L-30L dealer's packaging and the heavy packages for reaching 700L.

LDPE/HDPE/LLDPE/VLDPE/EVA multilayer material laminated films, aluminized mylar (common aluminium-plated bag), PP Plastic foil and nylon film are often used as the manufacture of currently the majority bag body.And new thermoplastic of good performance goes out It is existing, then considerable improvement is brought to shelf-life and physical characteristic.The external hard plastic box of storage bag body can be simple With or without the corrugation carton box of colored printing, fiberboard, soft iron bucket or folding carton (recyclable).Generally, corrugation box is applicable Product below 20 kilograms of net weight, so as to artificial lift, the most handy machine of bigger packaging is carried.Seal the valve on bag body Door has several kinds of forms --- operate valve etc. from the simple finger pressure by cap to complexity.Valve is in itself using unique injection casting Mould technology is revealed to prevent stopping leak.

But the bag body of bag in box currently used in the market, it is most of all exist one it is obvious the defects of, be exactly to fall When going out, flowing out internal liquid or solid, the residual quantity stayed in bag body is too many, causes larger waste, have impact on bag in box this The kind larger range of popularization and application of packaged form.

The content of the invention

Goal of the invention：For existing bag in box bag body residual quantity it is too many, cause the defects of larger waste, ad hoc meter is a kind of The bag body of bag in box with guiding gutter, material residual is reduced, avoids wasting.

Technical scheme：A kind of bag body of the bag in box with guiding gutter, including inner bag, outer bag, the mouth of pipe, the inner bag and outer The edge thermoplastic of bag is enclosed in together, and the mouth of pipe is enclosed in the middle part of inner bag and outer bag by thermoplastic, and the inside of the inner bag is provided with Guiding gutter that is some parallel to each other and being connected to the mouth of pipe.

Preferably, the guiding gutter is molded over the inside of inner bag by thermoplastic techniques.

Preferably, the inner bag is made of polythene material；The outer bag is metal coating.

Beneficial effect：The utility model is connected to the mouth of pipe by the guiding gutter in inner bag, is advantageous to the thing inside bag body Material residual directs into flow out at the mouth of pipe, effectively reduces residual, avoids wasting, saves material.
