Abstract
The utility model relates to a liquid storing bag. A film bag cylinder which is opened and is funnel-shaped is arranged at the bag opening point of the bag body of the storing bag, the right and left sides of the film bag cylinder are provided with wing edges, the opening of the bag cylinder is sealed into integration with the opening of the storing bag, the lower part of the bag cylinder extends into the inner chamber of the storing bag with the wing edges, and the wing edges are sealed with the both lateral sides of the storing bag. The utility model uses the hydraulic pressure and the surface tension of the liquid to cause the funnel opening of the film bag cylinder to be automatically closed, and the liquid in the bag is protected form reversely leaking. The utility model has the advantages of simple structure and convenient and sanitary use, can be used as a storing bag for the ordinary liquid or liquid matter, and is particularly suitable for being used as a sanitary cleaning storing bag for passengers.
Description
The utility model relates to the self-sealing pack for liquids of a kind of energy.
At present in communications and transportation, particularly air transportation is extensive use of a kind of health of adorning vomitus for the passenger and stores sack, and this sack does not have closing device, is easy to generate because of sack to topple over the contaminated problem of environment that makes.
The utility model provides a kind of liquid storage bag, and this sack can be easily to liquid or the flowing material of wherein packing into, and when it is toppled over, can automatic sealing, prevent that the content in the bag from spilling.
The purpose of this utility model is to realize like this, its structure is that one of the sack place liner of this reservoir bag bag opens and is bell-shaped bag film tube, have wing limit about said bag film tube, the sack sealing-in of its bag nozzle and reservoir bag bag is integral, the inner chamber of reservoir bag is stretched into together with wing limit in the bottom of bag tube, the dual-side sealing-in mutually of its wing limit and reservoir bag bag.
The utility model can adopt following concrete structure: said reservoir bag bag is made of the front and back bag face that connects along the side envelope; Said bag film tube comprises that then two width are folded mutually with the cooresponding film of reservoir bag face width, has two tiltedly to seal infundibulate face and the two flank limits that the limit makes its formation centre in its both sides.To be lining in the sack and the following place of reservoir bag in this bag film tube, the sack sealing-in of its bag nozzle and reservoir bag is integral, its wing limit can with the dual-side sealing-in mutually together of reservoir bag bag.
Store bag and can adopt the waterproof paper moulding material, both be convenient to the bag hot-pressing, edge-sealing and be shaped, again can compliance with environmental protection requirements.
The utility model is owing to be lined with one in the sack place of reservoir bag and open and be bell-shaped bag film tube, thereby liquid or flowing material easily from sack through pack into the inner chamber of reservoir bag of the bell mouth of bag film tube, and when reservoir bag is toppled over, liquid or flowing material flow backwards to sack, space between filling sack place's reservoir bag and the bag film tube, because hydraulic pressure and surface tension that liquid or flowing material own wt form, the bell mouth of bag film tube is sealed automatically, stoped the outflow of liquid or flowing material.The utility model is particularly suitable for doing the health storage sack of adorning vomitus in the communications and transportation, particularly air transportation for the passenger, also can be used as the packaging bag of general storaging liquid or flowing material.Has hygienic advantages simple in structure, easy to use.
Configuration state scheme drawing when Fig. 1 does not open for the utility model;
Configuration state scheme drawing when Fig. 2 opens for the utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
As shown in drawings, this liquid storage bag even constitutes bag 1 by front and back bag face (adopting the paper material) along the side envelope, in bag film tube 2 of sack place liner, this bag film tube is superimposed by two diaphragms, the bag face width degree of the width of diaphragm and reservoir bag is suitable, both sides on two diaphragms form two and tiltedly seal limit 3, make two tiltedly to seal formation one infundibulate face between the limit, and on formation wing limit, both sides, the bag nozzle of bag film tube 2 and the sack sealing-in of reservoir bag are integral, and the both wings limit is clipped in and is integral with the side sealing-in on the side of bag face before and after the reservoir bag, promptly makes this liquid storage bag.The thick dotted line of drawing among the figure is represented the sealing-in line.
