Abstract

The utility model relates to a gravity flow storage container. An outer housing of the storage container is provided with air holes which eliminate negative pressure generated after a store flows out and an opening, and the opening is provided with a cover or a gate valve. The inner part of the outer housing is provided with a bag which contains the store and causes the store to be isolated from the outer housing and air. The utility model can effectively isolate stored matter from being in contact with and being polluted by outer air and other foreign matter. The utility model is suitable for automatic water dispensers of mineral water and distilled water, supplying equipment of drink with normal pressure and temperature and low temperature, medical intravenous drip and blood transfusion equipment and various equipment with the same or stricter quality ensuring requests.

Description

A kind of gravity holder

The utility model relates to a kind of gravity holder, is meant especially a kind ofly can effectively completely cut off the gravity holder that extraneous air and other foreign matters enter the object of adorning.

Commercially available and commonly used at present all kinds of automatic mineral spring, distilled water water dispenser, normal pressure and temperature and low temperature drink supply arrangement, medical intravenous drip equipment, and each class I liquid I, flowable that identical or stricter insulation request arranged preferably solid supply with or perfusion equipment, have critical defect aspect guaranteeing the quality keeping a public place clean.Mainly show as in use, because the institute's liquid or solid material of adorning outflow the time forms negative pressure in container, must be by importing and exporting or air extractor vent imports air, the material of adorning is subjected to the pollution of the foreign that enters with the particulate in the air admission material, bacterium and from air extractor vent.According to October 12 " Liberation Daily " in 1998, the family, Shanghai " was found floating a colored pin mosquito in the bucket " in using the water fountain bucket of half; Another user " when water is drunk surplus half barrel, finds to finish in the bucket cockroach adrift ".

In addition, when implementing to instil for patient, use large size syringe needle and plastic pipe to solve the instillation soup bar none and flow out the negative pressure that the back is produced in hospital.Do not having under the airfiltering situation, bacterium will inevitably enter soup with airborne showy particulate, and then enters human body.To this, as carry out strict hygienic standard, the sterilization of this type of gravity holder and cleaning cost will inevitably can be in any more, influence consumption and production.

Existing technology with negative pressure in the normal pressure air-tight manner solution container, two-layer aseptic vacuum plastic packaging bag is adopted in the design of bags of blood when for example transfusing blood, and inner bag intensity is low, soft, and outer bag is harder, is convenient to hang; Along with the instillation of blood, barometric pressure shrivels packaging bag gradually in the use.Though this mode practicality but cost height, packing can not reuse, thereby is difficult to promote the use of.

The purpose of this utility model provide a kind of can effectively completely cut off with extraneous air and other foreign matters contact, enter the gravity holder of the material of adorning.

The utility model provides a kind of gravity holder that splendid attire material and extraneous air and other foreign matters are effectively isolated, the holder shell is provided with opening, opening part has lid or gate valve, there is a splendid attire to store thing in the shell, making the bag that stores thing and shell and air insulated is soft inner bag, has to eliminate on the holder shell to store the air extractor vent that logistics goes out the back negative pressure that produces.Bag is sealing bag or vacuum bag, and the profile of bag and the shape of holder shell are complementary.

The utility model is with simple technology, and little input less or not change equipment has realized effectively completely cutting off extraneous air and other foreign matters are connected into the material of adorning, has reached and fully kept a public place clean and guarantee the quality.By the negative pressure catheter on permanent closure or the cancellation existing installation, thoroughly break off material and outside contact channels, reach and keep a public place clean, the purpose of guaranteeing the quality.At this moment can the lower hygienic standard of corresponding execution, only need gravity holder is simply cleaned and sterilizes, reduced productive costs.The utility model can not cause any wasting of resources and environmental pollution, and the inner bag that is easy to use is concentrated to regain again and utilized.

Accompanying drawing is that the utility model one is implemented the complete section face scheme drawing of falling.

It is flask that accompanying drawing is given the main body of the gravity holder that shows, have in the shell 1 and the corresponding bag 4 of bottle shape, running condition is applicable to commercially available and commonly used all kinds of automatic mineral spring, distilled water water dispenser for being inverted, normal pressure and temperature and low temperature drink supply arrangement, medical intravenous drip equipment.Have air extractor vent 2 on wall of container, air extractor vent is opened at the bottom of bottle in this example, and shell is made with duroplasts.Opening 3 on the shell is bottleneck or is called import and export that import and outlet can split as required or be shared at this.Make the bag of institute's storage material and shell and air insulated claim soft inner bag again, can be common aseptic packaging or sterile vacuum packing.This bag available polyethylene plastic blown becomes bag film, cooperates all kinds of hard shells to make all size and pattern, is that the bottleneck shape promptly has bottleneck and import and export as sack; Sack also can be common straight-line joint type, is applicable to the output that can carry out after extraneous hard thing thrusts.The shape of gravity holder also can be slot type, pot type or other suitable shapes.Because graphic flask is just put in the transportation, foreign matter might enter the soft inner bag of damage in the container by air extractor vent, so there is a dividing plate at the place at the holder inner bottom part, both can prevent that foreign matter from entering, can in use oppress soft inner bag again and discharge institute's storage material by gravity.

Add man-hour, with the air in the bag of making take out fully extrude and sterilize after, be folded into the shape of being convenient to put into holder.During use, soft inner bag can expand with the input of content material, output and dwindle gradually, and the positive and negative air-pressure that is produced is then offset by the air of the turnover of the air extractor vent from shell therebetween, thereby guarantees that the content material can pour into and flow out swimmingly.When pouring into material, with existing sealing arrangement vacuumize, sterilization, closed container mouth can dispatch from the factory.For present popular water dispenser, install isolation package additional after, need only on the other sidewall at the bottom of the water bottle that former water dispenser is used or the end, bore several apertures in the non-stress place, make in the air admission bottle, flow out the negative pressure that the back forms to solve drinking-water, the original induction opening of shutoff simultaneously.But as being open form at the bottom of the bottle--unscrewing type, hung and buckled, then can sell the water courage separately is packed water, at this moment needs suitably to improve the intensity of bag.In like manner the medical dripping device of Sheng Chaning does not re-use the air intake structure that large size syringe needle and plastic pipe are formed.

Claims (3)

1. gravity holder, holder shell (1) is provided with opening (3), opening part has lid or gate valve, it is characterized in that having in the shell splendid attire to store thing, make the bag (4) that stores thing and shell and air insulated, on the holder shell, have to eliminate to store the air extractor vent (2) that logistics goes out the back negative pressure that produces.

2. gravity holder according to claim 1 is characterized in that bag is sealing bag or vacuum bag, and the profile of bag and the shape of holder shell are complementary.

3. gravity holder according to claim 1 is characterized in that there is dividing plate at holder inner bottom part place.
