Abstract
The utility model discloses a stainless steel vacuum heat insulating cup which comprises a cup cover (2), an inner cup body (3) and an outer cup body (4), wherein the outer cup body (4) is sheathed outside the inner cup body (3) and connected with the inner cup body into a whole on a cup opening. A vacuum layer (6) is formed between the inner and the outer cup bodies (3, 4), and the bottom part of the outer cup body (4) is provided with a vacuum pumping seal opening (9). The outer cup body (4) is sheathed with a protective body (5) which is fixedly connected with the outer cup body into a whole on the cup opening part. The vacuum pumping seal opening (9) is positioned in an empty clamping layer (9) which is formed between the outer cup body (4) and the protective body (5). The inner surface of the inner cup body (3) is coated with a non-stick layer (8). After the structure is used, the vacuum pumping seal opening is positioned in the empty clamping layer. The vacuum layer and the vacuum pumping seal opening can not be damaged by fall, touch and crash. Thus, the heat insulating effect can still be kept in vacuum invalidation. The heat insulating effect is good, and the appearance does not have a bottom cover or the vacuum pumping seal opening. The utility model has the advantages of simple structure, good heat insulating performance, convenient cleaning, beautiful and graceful entirety, long service life, etc.
Description
One, technical field
The invention relates to a kind of thermos cup, particularly a kind of vacuum cup made from stainless steel material.
Two, background technology
The stainless steel thermos cup that uses is made of inside and outside cup now, the bottom of cup is provided with vacuum-pumping and sealing outside, many hearts all can cause leakage in the bad or use of vacuum seal envelope, make vacuum cup not have the effect of insulation, directly influence the service life of thermos cup.Not fragile in order to guarantee vacuum seal, the general bottom of cup outside installs plastic bottom cover or stainless steel bottom additional, because be difficult to good fixing between bottom and the outer cup, bottom is easy to break or break off the base, causes the incomplete or vacuum failure of thermos cup and can't use; Next is after cup adds bottom, between cup and bottom lapping defect is arranged, and influences overall appearance; The easy fouling of interior besides cup is difficult to clean.
Three, summary of the invention
In order to overcome the disadvantage that existing stainless-steel vacuum thermos cup bottom damages easily, overall appearance is indecency and be difficult to clean, the invention provides a kind of cup three-decker, outward appearance one and the vacuum seal stainless-steel vacuum thermos cup in the folder dead level.The invention solves the technical scheme that its technical problem adopts and comprises bowl cover, interior cup and outer cup; in being enclosed within, outer cup fuses outside the cup and at rim of a cup; between inside and outside cup, form vacuum layer; the bottom of cup is provided with vacuum-pumping and sealing outside; be with protective on the described outer cup and fixedly fuse at the rim of a cup place; form the folder dead level outside between cup and the protective, vacuum-pumping and sealing is in the folder dead level.
The cup inner surface is coated with antistick layer in described.
After adopting said structure, be with protective on the outer cup, vacuum-pumping and sealing is in the folder dead level, fall, bump, hit and can not injure vacuum layer and vacuum-pumping and sealing, therefore can be because of vacuum failure does not have heat insulation effect yet, heat insulation effect is better, and outward appearance does not have bottom, no vacuum-pumping and sealing; Inner surface at interior cup applies antistick layer, is convenient to clean; Have simple in structure, good heat insulating, sanitation and hygiene, advantage such as overall appearance is generous, use is firm, the life-span is long.
Four, description of drawings
Fig. 1 is the structure schematic diagram of the invention.
Five, the specific embodiment
Shown in Figure 1, specific embodiments for a kind of stainless-steel vacuum thermos cup of the invention, it comprises bowl cover 2, interior cup 3 and outer cup 4, in being enclosed within, outer cup 4 fuses outside the cup 3 and at rim of a cup, form vacuum layer 6 between inside and outside cup 3,4, the bottom of cup 4 is provided with vacuum-pumping and sealing 9 outside, is with protective 5 on the described outer cup 4 and fixedly fuses at the rim of a cup place, form folder dead level 9 outside between cup 4 and the protective 5, vacuum-pumping and sealing 9 is in the folder dead level 9; Cup 3 inner surfaces are coated with antistick layer 8 in described; Described bowl cover 2 is provided with protecting cover 1.
Claims (3)
