Abstract

The utility model discloses a stainless steel metal heat preservation glass liner, the inner tube and the urceolus of this glass liner are made by the stainless steel, compare with original glass heat preservation glass liner, and this glass liner intensity is high, toughness is big, can take precautions against earthquakes, longe-lived, the heat preservation is effectual, can be applicable to all occasions such as family, field, car. The utility model can be matched with the upper cover, the base, the handle and the like to form an attractive, luxurious, safe and sanitary thermos bottle.

Description

Stainless steel liner of thermos flask

The utility model relates to a kind of glass liner of thermos, particularly can be applicable to the stainless steel metal glass liner of thermos of any occasion.

Its inner core of glass liner of thermos and the urceolus of selling on the market made by glass at present; because glass itself is frangible; be unable to undergo vibrations; so the life-span is shorter, exploding suddenly and the people is scalded appears in regular meeting after use a period of time, lives to people and has brought bigger inconvenience; particularly family has that child's feel worried especially; simultaneously this glass liner also because glass frangible can only be confined to family and use, can not be satisfied with on field and the automobile and use.With the exception of this, its outer tube bottom of existing this glass vacuum flask all has a taper to find time to seal mouth, thisly finds time to seal mouth and gives prominence to outside the surface, does not notice slightly and will be broken that in case break, this glass liner will lose gets vacuum, no longer insulation.

The purpose of this utility model is to provide a kind of safe in utilization, metal heat preservation glass liner that can be shockproof, this glass liner life-span length, high insulating effect, can be applicable to all occasions.

For achieving the above object, the solution that the utility model adopts is: the inner core and the urceolus of glass liner of thermos are made with stainless steel.

In the above-mentioned solution upper end eck of glass liner of thermos inner core be "

" shape, " " top of shape is that cambered surface is dehisced, protrude to the center at the middle part, and the bottom is another its bending direction and the top cambered surface opposite cambered surface of dehiscing.

The mouth of finding time of glass liner of thermos is the through hole that passes outer tube bottom in the above-mentioned solution, and the sealed knot plate of sealing process is together arranged on the through hole.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Accompanying drawing is a profilograph of the present utility model.

In the accompanying drawing, the utility model comprises inner core and urceolus, inner core is made up of cylindrical shell 1a and tube end 1b, urceolus is made up of cylindrical shell 2a and tube end 2b, it between inner core and the urceolus airtight vacuum district 4 of insulation effect, different with former glass liner of thermos is, the inner core of this glass liner and urceolus all adopt stainless steel to make, among accompanying drawing the utility model embodiment, all adopt between cylindrical shell 1a and tube end 1b, cylindrical shell 2a and the tube end 2b to be welded to connect, at the bottom of the cancave cambered surface, this considers from view of production technology under being that tube end 1b and 2b adopt, its objective is the minimizing manufacture difficulty, economical with materials.

For guaranteeing this stainless steel glass liner of thermos, and make it have good performance in the feasibility of producing, the upper end eck of this glass liner of thermos inner core be "

" shape, as figure, "

" top of shape is the cambered surface 1a that dehisces ₁, this 1a that dehisces ₁Be directly to cooperate, adopt this shape cambered surface to dehisce to have two effects with loam cake: the one, prolong heat conduction distance, store the energy of liquid to reduce inner core; The 2nd, increase the support point of inner core, so that disperse the stressed of tie point, made it force structure preferably, be unlikely to as glass refills because the bending force of bottleneck causes destruction too greatly, in the accompanying drawing, the cambered surface 1a that dehisces ₁Be down a part 1a who protrudes to the center ₂, projection 1a ₂Under be its bending direction and the top cambered surface 1a that dehisces ₁Opposite cambered surface 1a ₃, i.e. 1a ₃Cambered surface is to fovea superior.Above-mentioned whole "

" the shape eck directly adopts mould to extrude on straight barrel 1a and form.Adopt "

" the shape eck, both saved material, reduced weld seam again, strengthened bulk strength simultaneously, reduced the possibility of finding time to leak gas.

Mouthful 2b that finds time of the present utility model ₁, as figure, be the through hole that passes outer tube bottom 2b, a mouthful 2b finds time ₁Sealing adopts is a sealed knot plate 3, this sealed knot plate 3 is finished the back of finding time because inner vacuum action and closing naturally, after closing, fixing by welding on every side, because sealed knot plate 3 usefulness stainless steels are made and be consistent with the cambered surface of 2b at the bottom of the urceolus tube, thereby postwelding does not leave outstanding envelope mouth in the closure part surfacing, when this glass liner and external items are collided, can not lose insulation effect because of the destruction of envelope mouth.

The utility model is made by stainless steel owing to cylindrical shell itself, so can be used as bottle shell on outward appearance and intensity fully uses, as long as be equipped with plastics annexes such as loam cake, base, handle on urceolus 2, that the utility model can become is attractive in appearance, luxurious, the thermos flask of safety, health.

The utility model is because inner core and urceolus adopt stainless steel to make, the inner core eck adopted "

" shape, the mouth of finding time has simultaneously adopted sealed knot plate sealing, thus the utility model is compared with original glass refills and is had following advantage: and (1) intensity height, toughness is big, energy is shockproof, the life-span is long; (2) the vacuum height of taking out, high insulating effect; (3) cold and hot strong adaptability can not produce blast, uses safety; (4) can be applicable to all occasions such as family, field, automobile.
