Abstract
The utility model discloses an anti -pollution bottleneck seal structure, which comprises a bottle body and a bottle cap, the bottle oral area from top to bottom includes a smooth bottle neck and a boss interface part in proper order, the bottle lid is provided with a blind hole for the lid column structure that is provided with a countersunk head mouth and the middle part of countersunk head mouth, the bottle lid connects in the outside of the boss interface part of bottle oral area through the countersunk head mouth soon, and it set up original direct screw thread with the direct contact of bottle neck portion on convex structure through set up a convex structure in bottleneck department, can avoid the pollutant entering into screw thread department like this, and the bottleneck is smooth also comparatively comfortable during human oral area contact when drinking.
Description
Technical field
The utility model relates to bottle sealing technology, is specifically related to a kind of anti-pollution bottleneck seal structure.
Background technology
Now bottled food, beverage etc. are a lot of on the market at present, conventional sealing tech is all adopt screw thread to spin, the interior end of bottle cap, is provided with packing seal, ensure vacuum state in bottle, this kind of structure structure is simple, can ensure that in bottle, vacuum is pollution-free, then bottle cap screw thread oral area cannot be accomplished anti-pollution, during use, whorl of bottleneck place directly contacts with human body oral area, and screw thread oral area also may touch liquid in bottle, and this all can affect our healthy diet.
Utility model content
(1) technical matters that will solve
In order to overcome prior art deficiency, now proposing a kind of anti-pollution bottleneck seal structure, which raises the edible safety of ampuliform beverage or food.
(2) technical scheme
Of the present utility modelly to be achieved through the following technical solutions: the utility model proposes a kind of anti-pollution bottleneck seal structure, comprise bottle and bottle cap, described bottle oral area from top to bottom comprises a smooth bottle neck and a tower interface portion successively, described bottle cap is be provided with the lid-like of a countersunk head mouth and the middle part of countersunk head mouth is provided with a blind hole, and described bottle cap is rotatably connected in the outside in the tower interface portion of bottle oral area by countersunk head mouth.
Improve as one, the bottom of described blind hole is provided with gasket sheet.
As further improvement, fit between position in the bottom surface of described countersunk head mouth and tower interface portion upper surface and be provided with annular seal ring.
As further improvement, the place in the bottom surface of described countersunk head mouth or both upper surfaces in tower interface portion is provided with lines.
As further improvement, between described smooth bottle neck and blind pore wall, leave 1-2mm gap.
(3) beneficial effect
The utility model, relative to prior art, has following beneficial effect:
The anti-pollution bottleneck seal structure of the one that the utility model proposes, it is by arranging a boss structure at bottle mouth position, original screw thread directly directly contacted with bottle neck portion is arranged on boss structure, pollutants can be avoided like this to enter into screw thread place, can pollute when drinking or get, on the other hand, boss structure plane is also provided with an annular seal ring, it can improve the sealing effectiveness in bottle, simultaneously also preventing pollution further, bottleneck is smooth also comparatively comfortable during the contact of human body oral area when drinking.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The anti-pollution bottleneck seal structure of one as shown in Figure 1 to Figure 3, comprise bottle 1 and bottle cap 2, described bottle 1 oral area from top to bottom comprises smooth bottle neck 11 and a tower interface portion 12 successively, described bottle cap 2 is provided with a blind hole 22 for the middle part of the lid-like and countersunk head mouth 21 that are provided with a countersunk head mouth 21, and described bottle cap 2 is rotatably connected in the outside in the tower interface portion 12 of bottle 1 oral area by countersunk head mouth 21.
Wherein, the bottom of described blind hole 22 is provided with gasket sheet 3; Fit between position in the bottom surface of described countersunk head mouth 21 and tower interface portion 12 upper surface and be provided with annular seal ring 4; A place in the bottom surface of described countersunk head mouth 21 or both upper surfaces in tower interface portion 12 is provided with lines; 1-2mm gap is left between described smooth bottle neck 11 and blind hole 22 wall.
The anti-pollution bottleneck seal structure of one that above specific embodiment is mentioned, it is when specifically using, bottle cap 2 screws in bottle 1 top, the flank threads in tower interface portion 12 and the screw thread fit of countersunk head mouth 21 medial surface screw, countersunk head mouth 21 bottom surface and surface, tower interface portion 12 are by annular seal ring 4 press seal, bottle 1 bottle mouth position also well seals by the gasket sheet 3 simultaneously bottom blind hole 22, even if the screw thread mouth of side, tower interface portion 12 is contaminated, smooth bottle neck 11 also can not be polluted, and substantially increases safety when people drink.
Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
