Abstract

The utility model discloses a tailless thermos bladder, which comprises an inner bladder, an outer bladder and a bladder coating layer, wherein three asbestos pads between which angles of 120 DEG are formed are arranged between the inner bladder and the outer bladder. A gypsum tail eliminating supporting pad is arranged on a contraction interface of a tail pipe between the inner bladder and the outer bladder. The utility model fundamentally solves the problem of easy crash of the residual tail pipe of a thermos. The prepared tailless thermos bladder can not be easily damaged in the process of transportation, assembly and utilization. The utility model has the advantages of beautiful appearance and good effect of thermal insulation. According to the test of the first and the fourth items of QB182-81, the temperature of water in a thermos bladder with the capacity of 2000 milliliters and the weight of 500 grams is no less than 70 DEG C after 24 hours.

Description

Tailless thermos bottle inner bag

Technical field

The utility model relates to a kind of container with heat insulation function and preparation method thereof, more particularly relates to a kind of family expenses Tailless thermos bottle inner bag.

Background technology

Having many uses of vacuum flask can be used for storing hot water, holding cold drink and medicine, and the critical piece that plays insulation effect in vacuum flask is a glass liner of thermos.Glass liner of thermos used in everyday all leaves a tail pipe usually in the bottom.Because it is very thin that the tail pipe of vacuum flask is given prominence to the wall of outside at vacuum flask, tail pipe, this just causes glass liner of thermos tail pipe position in transportation, assembling and use to be damaged especially easily, causes glass liner of thermos to lose heat preservation effect.China utility application 00219709.X, publication number 2426717, name is called " glass liner of thermos ", discloses a kind of improved glass liner of thermos, this glass liner of thermos includes inner bag, outer courage, glass liner coating, it is characterized in that being provided with tail pipe at the inner surface of inner bag.Because tail pipe is arranged on the inside of glass liner of thermos, thus this utility model transport and use in tail pipe cracky not.But this utility model exists tail pipe to rupture to the potential danger of glass liner of thermos inside, safety inadequately, and preparation technology is more complicated also.

The utility model content

At the problems referred to above, technical problem to be solved in the utility model provides a kind of glass liner of thermos that does not have tail pipe, this glass liner of thermos high insulating effect, profile are more attractive in appearance, transportation, assembling, use safer.

To achieve these goals, the technical scheme that is adopted: a kind of Tailless thermos bottle inner bag, comprise inner bag, outer courage and glass liner coating, be equipped with three asbestos pads that are mutually 120 ° between inner bag and the outer courage, tail pipe shrinks and to be equipped with the gypsum tail pad that disappears on the interface between inner bag and the outer courage.

Described asbestos pad is arranged on the middle part of Tailless thermos bottle inner bag.

The beneficial effects of the utility model are: there is not residual tail pipe in glass liner of thermos described in the utility model, has fundamentally solved the frangible problem of residual tail pipe.Interior, add the gypsum tail pad that disappears between outer glass liner, the gypsum tail pad that disappears plays a supportive role after shrinking in that tail pipe is softening, has also disperseed the external force that inner bag bore, and makes glass liner firmer.This gypsum tail pad that disappears can also play the getter effect between the vacuum cavity of inside and outside courage, guarantee that vacuum flask has good vacuum.The Tailless thermos bottle inner bag of the utility model preparation cracky not in transportation, assembling and use.Heat insulation effect is good.Press 1,4 test of QB182-81, capacity is that 2000 milliliters, weight are that glass liner of thermos water temperatures in the glass liner after 24 hours of 500 grams are not less than 70 ℃.

Description of drawings

Fig. 1 is described Tailless thermos bottle inner bag structural representation.

The specific embodiment

In conjunction with the accompanying drawings the utility model is described in further detail: as shown in Figure 1, Tailless thermos bottle inner bag described in the utility model comprises inner bag 1, outer courage 2, glass liner coating 3 and inside and outside glass liner asbestos pad 6, the outer surface of its inner bag 1 is provided with the gypsum tail pad 4 that disappears, its installation position is on the interior glass liner of eliminating 5 place correspondences behind the tail pipe, asbestos pad 6 is installed in the body middle part, the described gypsum tail pad 4 that disappears fixedly secures on the surface of inner bag 1, is of moderate size.

The preparation method of above-mentioned Tailless thermos bottle inner bag:

1, gypsum the installing additional of tail pad that disappear:

In body middle part, install additional between outer blank three be mutually 120 asbestos pads of spending after, install the gypsum tail pad that disappears additional, on the glass liner, it is suitable, firm to add holding position at tail pipe and outer blank interface and in being fixed in its position, its size is moderate, can not influence later process.

2, the glass liner of thermos anury is handled:

(1). glass liner of thermos is after vacuumizing and sealing, and tail pipe length should shorten as far as possible, is controlled at 10mm with interior comparatively desirable.

(2). should be rapidly after above-mentioned (1) step is finished evenly heat up in 200 ℃ of flames are bathed, make the tail pipe place and radius 50mm is with interior intensifications unanimity on every side, and radius is contracted in the 30mm about 30s of time gradually.

(3). improve gradually about temperature to 500～600 ℃, make the tail pipe thermally equivalent, this moment, tail pipe should be kermesinus, and shrank gradually.

(4). regulate lamp holder flame temperature is increased to about 800 ℃, adopt flame envelope, make it reach Microsoft's attitude rapidly the even Fast Heating of residual tail pipe 360 degree.After tail pipe was evenly heated and reaches Microsoft's attitude, on the gypsum of step setting disappeared tail pad 4 before externally tail pipe will shrink and abut under the gas pressure, cooling was solidified.Install the tail pipe pad additional and brought following benefit: the A. tail pipe is softening to be had after shrinking it to support can not to cause hypersystole and thin excessively causing broken.B. because tail pipe shrinks, reclines, the gypsum tail pad that disappears is firmly fixed after abovementioned steps is finished, can not come off because of vibrations.C. play the effect of getter at vacuum space, guaranteed vacuum.D. disperseed the external force that interior glass liner bore, made whole glass liner more sturdy and durable.

(5). the redundance after tail pipe shrinks, should in flame, its folder be removed with instrument, the temperature of instrument also should be consistent with the temperature of glass in the flame during operation.

(6). annealing: regulate lamp holder flame after above step is finished rapidly to crocus or blush (this moment, the temperature of flame was lower), annealing gradually under this state, about 30s of time.

More than each operating procedure must keep heating the uniformity of tail pipe temperature, otherwise local can cause than stress greatly and to break because of cold, the overheated generation with excessivelying, above process is finished about 2～3 minutes of total time, and should once finish from start to end, should not drop by the wayside flame and carry out the heating second time, otherwise very easily cause explosion.

Above said content only is the basic explanation under the utility model design, and according to any equivalent transformation that the technical solution of the utility model is done, all should belong to protection domain of the present utility model.
