Abstract

A kind of cool-bag that relates to daily container, its wall are the leak free plastic sandwich, and vacuum is pumped in the space in the interlayer, can refill in mezzanine space into getter material, can apply the thin bright metal of one deck on the wall of interlayer.This cool-bag is compared with general vacuum bottle, can not need the screened housing of outside, and have good heat-insulating property, thereby greatly reduce cost of product and simplified production technology, produces huge economic benefit.

Description

Thermal-insulating container with plastic sandwich wall for vacuumizing

The present invention relates to preserve the container of article, relate more particularly to the container that can be incubated.

That the cool-bag of prior art resembles is cold, warm vacuum bottle, is made up of glass liner, screened housing and lid.Glass liner is the glass container of an interlayer, and interlayer is a leak free, and vacuum is pumped in the inside; the silver layer that light is arranged in the surface coating of glass; the glass liner of glass is contained in the screened housing, and screened housing plays a part cover glass glass liner and beautifying and decorating, and bottle cap is used for sealing or the unlatching glass liner.This cool-bag prevents that cross-ventilated effect, evacuated glass sandwich have the conduction of the heat of preventing and the mask of light prevents thermal-radiating effect because the tight bottle stopper of lid has, so have good insulation effect.But also there are a lot of shortcomings in this vacuum bottle, do because glass liner is a glass, and interlayer is pumped into vacuum, thus be unable to undergo vibrations or bump, careless slightly, will break, sometimes even can reveal; Glass surface is silver-plated, will consume noble metal silver, because of the output of annual vacuum bottle huge, so will consume a large amount of noble metal silver; Because the interlayer vacuum-pumping, so can stay next outstanding glass-dead seal on wall, what this was outstanding seals, and is most fragile and the most damageable place in the glass refills, accidentally breaks up, and interlayer will leak gas, and glass liner just loses the effect of insulation; Because Glass breadks easily just must have screened housing protection, with regard to the function of insulation, this screened housing is unnecessary, but can not omit; Because glass can't cool working, hot working is also very difficult, so the opening of glass liner and the binding of bottle stopper can only be adopted the plain mode of simply bottle stopper being filled in the bearing fit of opening, can't adopt other routine threaded connection, bayonet socket to link or the like mode, further say in order to adapt to various needs and glass liner will be made very difficulty of various moulding, can only make basic drum type; Because Glass breadks easily and difficult processing are so in the process of making glass liner, condemnation factor is also very high.

The objective of the invention is to design a kind of cool-bag of the shell that do not need protection, the glass liner that is to say cool-bag also is its screened housing;

A further object of the present invention be design a kind of can be incubated and can be shock-resistant, the cool-bag of vibrations;

A further object of the present invention is the cool-bag of a kind of easy processing and manufacturing of design.

The present invention realizes by such design: a kind of cool-bag, the wall that the lid that cooperates hermetically by the heat-insulated container with opening with opening and can separate is formed the encirclement of described opening heat-insulated container is the leak free interlayer, the wall that surrounds defines a chamber, vacuum is pumped in space in the interlayer, and the wall of described encirclement is with plastic.

As a kind of variation, can be packed into getter material in the described evacuated mezzanine space.

As another variation, form the reflecting horizon that can cover one deck light on the surface of at least one wall of described interlayer.

Advantage of the present invention is tangible.Because cool-bag of the present invention has the wall that the interlayer of the vacuum of being pumped into surrounds, plastics are again the bad conductoies of heat, lid can seal binding preferably with opening, can overcome conduction, radiation and the convection current of heat like this, so this cool-bag has good heat insulation effect.Because plastics have stronger mechanical characteristics, and are shock-resistant, so this cool-bag need not screened housing, so just can reduce the cost of product greatly, the requirement of this product is huge, so can save a large amount of raw material metals, produces huge economic benefit.Because of plastics are easy to machine-shaping,, also be suitable for developing the kind of new cool-bag so can make the various shapes that are suitable for purposes.

Fig. 1 is a kind of constructed profile that the present invention conceives.

Fig. 2 is the section-drawing of another embodiment of the present invention.

Fig. 3 is the another example of cool-bag mouth of the present invention and the airtight binding of lid.

Shown in Figure 1, be a kind of embodiment of cool-bag, it is made up of heat-insulated container [1] and lid [6].Heat-insulated container [1] is that the leak free that a wall [2] that surrounds and a wall [3] that surrounds are formed surrounds interlayer wall [5] around forming, and interlayer wall [5] defines a chamber [6].The interlayer of interlayer wall [5] is a space [4], and vacuum is pumped in [4] in the space, and the interlayer wall [5] of encirclement is gone up and formed a mouth.The peripheral shape of lid [5] is consistent with the shape of interlayer wall mouth, and lid [6] can be filled in the mouth heat-insulated container is airtight, can remove again mouth is opened.Described interlayer wall [5] is made of plastics, for example compositions such as melamine plastics, acrylic plastering, ABS plastic, vinyon, polytetrafluoroethylplastic plastic also can be provided with some daggers [16] and support interlayer [2], [3] to increase the rigidity of interlayer wall [5] between the wall of interlayer [2], [3].Evacuated space also can charge into getter material in [4], for example the alkoxide of alkali alcoholate or alkaline earth.The metal level that on evacuated space face on one side, can apply one deck light of wall [2] or wall [3], for example silver layer or aluminium lamination.

As shown in Figure 2, be a kind of variation of the present invention.The structure of heat-insulated container [8] is similar with heat-insulated container [1] shown in Figure 1 basically, and is just slightly different in shape, so be not described in detail its structure.The circle spiral salient [9] that has at the access hole place, this spiral salient [9] is not continuous, the centre has openning, there are several sections with the corresponding projection [11] inwards of openning on the lid [10], in the time will covering tight lid [10], projection [11] just snaps in the below of spiral salient [9] by the openning of spiral salient [9], and swivelling cover [10] just will cover [10] with the heat-insulated container lid tightly then.Handle [12] links to each other with the wall of heat-insulated container.The heat-insulated container seat is in the end [13], and the end [13] and heat-insulated container 8 can be with hot weld method solder togethers or with adhesive bond together.

As shown in Figure 3, be the another variation of the binding of heat-insulated container of the present invention and lid.On heat-insulated container, can make outside thread [14], can make the negative thread [15] that matches with outside thread [14], cover the mouth that just can be screwed in container then and upward it is shut or opens at the inwall of lid.
