Description
Technical field:
The present invention relates to a kind of method and device of storing volatile liquid, particularly a kind of method and relevant apparatus that utilizes the long preservation that the double-layer seal technology realizes volatile liquid belongs to field of product packaging.
Background technology:
Long preservation problem with volatile liquid is a technical barrier always, around this problem, has produced a series of correlation technique, for example special-purpose barometric metallic seal jar etc. that has.For the wine that belongs to the current consumption articles for use, glass or ceramic bottled container are the most frequently used schemes.The liquid encapsulation bottle that has bottle cap or bottle stopper is the most frequently used device of storing wine, and still, the sealing of liquid encapsulation bottle is a weak link, also is that rotten major cause takes place in long term storage wine.By improving the structure of bottle cap and bottle stopper, can realize better seal, still, for the long term storage of wine, still there is following problem in the sealing of current liquid encapsulation bottle:
The one, because technological reason, there is certain slit between bottle cap or bottle stopper and the bottleneck unavoidably, be difficult to seal fully, for wine, particularly this class of high spirit has volatile liquid, occurs the volatility leak case easily, but this leakage, long-term storage is difficult in a short time find, if will influence the quality of product greatly.
The 2nd, the bottle cap of current employing, bottle stopper often adopt the plastics manufacturing, through after the long period, particularly are exposed in the air, various catabiosis occur, and sealing property also descends thereupon.
The 3rd, bottle of liquor does not finish if drink after opening bottle, wishes what continuation was preserved, current liquid encapsulation bottle, and its bottle cap or bottle stopper are difficult to excellent sealing once more.
The problems referred to above for the short-term of common wine is preserved, are ignored easily, but for the long preservation that is worth higher wine, are not addressed the above problem well, tend to bring bigger loss.At application number is in the application for a patent for invention of 200410097095.X, a kind of Wine preservation system is disclosed, this system imports the wine of preserving in the liquid encapsulation bottle in the opened liquid encapsulation bottle by making a kind of unreactable gas pass a sealing, sealing seals the liquid encapsulation bottle of before having opened, adapter is this liquid encapsulation bottle sealing, and unreactable gas passes described sealing and is injected into the liquid encapsulation bottle from a detouchable gas feeder.In above-mentioned patent, exist following technical matters: the one, the systematic comparison complexity in use needs inert gas source and aerator; The 2nd, unreactable gas is revealed easily, and adapter must can be good at sealing, causes the adapter structure complexity, and cost is higher; The 3rd, this system has increased a bigger adapter on liquid encapsulation bottle, be unfavorable for carrying and packing.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, a kind of method and special relevant apparatus that is applied to this method of easy to use, with low cost, reliable sealing storing volatile liquid is provided.
The technical scheme of the method for storing volatile liquid of the present invention is: this method may further comprise the steps: the volatile liquid that (1) will be to be stored is loaded in the liquid encapsulation bottle, the liquid level of volatile liquid is lower than bottleneck 3-10cm, fill in bottle stopper or build after the bottle cap, with the aquaseal jacket casing at bottleneck or shoulder position, and fill lining cement at the face of joint of aquaseal tube and bottleneck or shoulder, normal temperature solidified 2-24 hour down, (2) the aquaseal isolating cap is covered on the bottle cap or bottle stopper of liquid encapsulation bottle, and with 10-40 newton's pressure compression aquaseal isolating cap, the aquaseal isolating cap is well contacted with bottle cap or bottle stopper, (3) utilize the aquaseal ejector to inject aquaseal fast from the upper end open of aquaseal tube, the input speed of aquaseal is greater than 1 milliliters/second, cover the top 5-20mm of aquaseal isolating cap until aquaseal, at normal temperatures with sealant cures, (4) aquaseal tube seal closure is covered above the sealed chamber aquaseal tube seal closure and aquaseal tube screw thread fit.
Above-mentioned steps is applicable to the storage of volatile liquid, consider the taking-up of the volatile liquid that utilizes the said method storage, also comprise the step of taking out volatile liquid in the technique scheme, be specially: (1) utilizes the aquaseal ejector that the aquaseal that has cured is fused, softens, and sucking-off from the aquaseal tube, (2) remove aquaseal isolating cap and aquaseal tube.Finish after the above-mentioned steps, can open bottle cap or bottle stopper, thereby the volatile liquid in the bottle is taken out according to the method for routine.
The fusing point of the aquaseal that adopts in the said method is lower than 150 degrees centigrade, and the main component of the aquaseal of employing can be paraffin.
The present invention has designed the device of a kind of storing volatile liquid of the method that is exclusively used in above-mentioned storing volatile liquid, comprise liquid encapsulation bottle, bottle stopper or bottle cap, the device of this storing volatile liquid also comprises the aquaseal tube, aquaseal tube seal closure, the aquaseal isolating cap, the bottleneck of aquaseal tube and liquid encapsulation bottle, perhaps shoulder forms and closely cooperates, aquaseal isolating cap one end is airtight, one end has opening, the internal diameter of aquaseal isolating cap is greater than the external diameter 1-5mm of bottle cap or bottleneck, the aquaseal isolating cap covers on the top of liquid encapsulation bottle, the internal diameter of aquaseal tube is greater than the external diameter 5-20mm of aquaseal isolating cap, and aquaseal tube seal closure and aquaseal tube form screw thread fit.
Above-mentioned aquaseal tube can be filled lining cement for highly being that the circle ring column of 5-15cm and the bottleneck of liquid encapsulation bottle closely cooperate at the fitting surface place.The aquaseal tube also can be funnel shaped, and the bottleneck and the shoulder formation of the inside face of aquaseal tube and liquid encapsulation bottle closely cooperate, and fill lining cement at the fitting surface place.
