Abstract
The invention relates to a liquid product capable of being completely hermetically packaged and a method for using the completely hermetically packaged liquid product, namely a method for bagging liquid in a solid container. Air return is prevented while packaging the effluent liquid by the method, thus avoiding secondary pollution caused by air return, and the container opening can be directly connected with an instrument by various connectors and be directly used. The liquid in a packaging bag does not contact the inner wall of the container, thus avoiding contamination to the inner wall of the container and causing the recycling of the solid container to be convenient and quick, and the use of the solid container can ensure the safety, convenience and operability of transportation, preservation and application of the liquid.
Description
Technical field
The present invention relates to the packing and the operation technique of liquid product, more particularly relate to the method for complete sealed package liquid product and this complete seal-packed liquid product of use.
Background technology
As everyone knows, if the liquid in the solids package container is come out, such as pouring out, emit or drawing with skirt, it is fluid, simultaneously must return isopyknic air or other gas in container, promptly return gas, guaranteeing has certain difference of pressure just can achieve the goal inside and outside the container.But in actual applications, this just causes original packaged liquid product to contact with returning gas, brings a lot of troubles and problem.
For example, widely used water dispenser bottled water in the daily life now, when bottled water just has been installed on the water dispenser and people when taking water, because in-to-in water is (general bottled water construction opening is downward) mobile fluid down, cause external and internal pressure not wait, air can be introduced fast, form people common to return gas bell.Because what introduce is indoor air, and in the room air because environment and all multifactor many dust that contain such as artificial, and dust can carry a large amount of germs, algae etc., and these germs, algae etc. are with can a large amount of breedings after returning gas and entering in the bucket, makes the bottled water will soon be contaminated.Behind the general bottled water Kaifeng, need the time about a week just to use up, two weeks just can not drink later.If long-time the placement, inwall can form tangible mould layer, thus require the bottled water behind the Kaifeng to use up as early as possible and can not place for a long time, and water dispenser regularly cleans with the water contact need that pollutes because of long-term.As seen returning gas is very serious to the pollution of bottled water and water dispenser.
For example, the intravenous fluid that patient uses always is as glucose injection, generally need the injection long period, its return gas can with the parenteral solution effect long period, it is dangerous more to consider that parenteral solution directly enters in the human body in the circulation and hospital air bacterium, germ and mould, more serious to patient's threat.This is why in a single day parenteral solution uses in Kaifeng, with regard to beyond economic repair basic reason.
For another example; some are to the reagent of water and air sensitivity; as be used for the synthetic anhydrous solvent of DNA; to extremely strictness (content requirement is lower than 10ppm) of moisture requirement; generally can only in the glove box of dry and inert gas shielding and environment, take and operation experiments; prepare for fairly large use of commercial production and various experiment, all brought many difficulties and trouble for equipment, technology, efficient and cost.
Now, people recognize that generally fluid returns the harm of gas, also attempt to have carried out various improvement.As in the bottled water field, people use packed water, negative pressure of vacuum water dispenser, no refill drinking machine, antibacterial material etc. instead; Parenteral solution is used packed liquid etc. instead; Airsensitive reagent adopts particular interface direct connection use etc.These improve more or less some effect, but from ease-to-operate, Transport Safety, long-time storage stability, Technological Economy etc. comprehensively, are not very perfect.These all require people to invent a kind of fluid that both solved and return dress liquid and relevant device in the gas pollution, can reach convenient, practical again and the technology of economy.
Summary of the invention
The objective of the invention is to relate to the method for the complete sealed package liquid product of a kind of energy and this complete seal-packed liquid product of use, promptly adopt the method for packed liquid in the solids container.When using, container to be inverted or tilting downwards, vessel port is connected with being subjected to liquid device or connector, and the admission port of container bottom is opened, and makes the liquid product in the packing can fluid because of action of gravity or a bag external and internal pressure.Because can introduce particularly atmosphere gas of gas from container bottom, in the fluid process, needn't resemble and commonly used return gas from the container finish position, avoided returning the secondary pollution that gas causes.Because the liquid in the existence of internal layer packaging bag, packaging bag does not contact with container inner wall, has avoided the pollution to container inner wall, it is simple and fast that the recovery of solids container is used again, and it is very favourable that this maybe needs to reclaim the situation of using container again for easy pollution.Owing to need not return gas,, need not consider to return the pollution of gas or environment so vessel port can directly be used by various terminal and instrument and equipment direct connection.Simultaneously, because the use of outer solids container can be guaranteed safe, the convenient and operability of transporting, preserving and using.
The present invention does not have the design of the gas of returning fluid, and referring to structural representation of the present invention, outer wall is the container that solid material constitutes, and solid material is glass, pottery, metal, plastics, resin etc., preferred glass and transparent plastic material.Container shapes is barrel-shaped, cylindricality, square, soccer star or other shapes that needs.Container bottom generally caves in, recess is installed into gas port, admission port can be designed as required pop can easy-tear type opening, also can be designed to spiral thimble type opening, also can be designed to the tapered opening of spiral, also can be designed to other Interface design that need such as the type of withholding, piston-type, mark mouth switching mode.Admission port is generally sealing in transportation and installation process, opens when adorning liquid in using, and air or atmosphere gas are entered.Vessel port can have multiple design as required, as screw thread mouth, bayonet socket, the mouth that turns blue, head space mouth, plug mouth and other interfaces that need.Internal layer is flexible pack for liquids, and material is for internally the plastics and the resin film of dress liquid long-term stability are made.Space coupling in the shape of packing inside bag and the container, dress liquid can stablize preservation for a long time and transport safely in guaranteeing.
During use, vessel port is linked to each other with use equipment,, generally be inverted or the inversion use of tilting as water dispenser, reactor, infusion connector etc.With air inlet open, be connected with the atmosphere gas system when needing, guarantee internal and external pressure balance.Open and use the related switch of equipment, interior dress liquid flows out, and can use.
