Abstract

The invention discloses a backflow bottle cap which comprises an outer cover, an inner cover and a backflow hole. The tubular inner cover is formed by an inner pipe and an outer pipe, the inner pipe is in sealed connection with a pipe wall in the middle of the outer pipe to form an annular cavity with the upper part open, a wall of the outer pipe of the tubular inner cover is matched with a bottle opening, the bottom surface of the annular cavity is provided with the backflow hole to be communicated with a bottle body, the inner pipe of the inner cover extends out of the bottom surface of the annular cavity to extend into the bottle opening, an appropriate included angle is formed between the extended end plane of the inner pipe and a pipe shaft, and an inclined sharp plane is shown in the pipe opening direction. Due to the fact that the inner pipe of the inner cover extends out of the bottom surface of the annular cavity to extend into the bottom opening, the appropriate included angle is formed between the extended end plane of the inner pipe and the pipe shaft and the inclined sharp plane is shown in the pipe opening direction, a liquid-solid contact surface area is small when tail liquid flows out of a dropping liquid separating point which is an inclined sharp face vertex; the tail liquid flows back to a bottle in a dropping mode more smoothly, and the advantages are more obvious when the backflow bottle cap is used for containing liquid high in viscosity.

Description

A kind of Recovering bottle cover

Technical field

The present invention relates to a kind of bottle cap, relate in particular to a kind of Recovering bottle cover.

Background technology

The fluids such as various bottled daily liquid flavoring, cooking oil and articless for washing, after each use, all can there is the tail washings of part to flow to along bottleneck on the outside face of bottle, and then flow on the table top of bottle rack, the time one is long, above dust drops on, can can't bear by the greasy of change, both unhygienic, contaminated environment is again very not attractive in appearance, for addressing this problem, people have invented various Recovering bottle covers.

As disclosed a kind of return bottle cap in: the Granted publication Chinese patent number for CN2419177Y, it is made up of enclosing cover, inner cap, return port, the inner cap of compound sleeve tubulose is made up of inner and outer tubes, the middle part tube wall connecting sealed of inner and outer tubes, form an annular chamber annular, upper opening, outer tube wall and the bottleneck of inner cap are suitable, and the bottom surface of annular chamber has return port and communicates with bottle.After in bottle, liquid is poured out, remaining in bottleneck liquid around can pass back in bottle by the return port of inner cap annular chamber bottom surface.

Adopt such technology certainly can reach the backflow of tail washings, keep the clean of bottle.But backflow dropping liquid separation point and inner cap annular chamber bottom surface be at same plane, tail washings flow out return port while being dropping liquid separation point liquid-solid contact face area larger, smooth and easy not when tail washings drip returns in bottle, during in particular for the larger liquid of dress viscosity, more obvious.Some bottle caps are also provided with return port, flame diversion trough, but due to the tension force of liquid, often stop up, and not smooth problem refluxes.

Summary of the invention

For overcoming the deficiencies in the prior art, the invention provides a kind of backflow dropping liquid separation point and inner cap annular chamber bottom surface not at same plane, when tail washings flows out dropping liquid separation point, liquid-solid contact face area is less, Recovering bottle cover more smoothly when tail washings drip returns in bottle.

The present invention for overcoming the above problems adopted technical scheme is: a kind of Recovering bottle cover, comprises enclosing cover, inner cap, return port; The inner cap of compound sleeve tubulose is made up of inner and outer tubes, and the middle part tube wall connecting sealed of inner and outer tubes forms an annular chamber annular, upper opening, and outer tube wall and the bottleneck of tubulose inner cap are suitable, and the bottom surface of annular chamber has return port and communicates with bottle; It is characterized in that: the bottom surface that the inner tube of inner cap is extended annular chamber is stretched in bottleneck, has a suitable angle between the transverse plane that inner tube is stretched out and tubular axis, is an oblique sharp face along mouth of pipe direction, have flow-guiding bar along return port to oblique sharp face tip.Had flow-guiding bar, with regard to not producing return port, flame diversion trough because the tension force of liquid and blockage phenomenon.

Described inner tube wall stretches in bottleneck part and is provided with one axial groove at the oblique pinnacle place of flushing and is connected with return port.

Described inner tube wall part on the bottom surface of annular chamber connects return port place and is provided with axial breach one.

The invention has the beneficial effects as follows: the bottom surface of extending annular chamber due to the inner tube of inner cap is stretched in bottleneck, between the transverse plane that inner tube is stretched out and tubular axis, there is a suitable angle, be an oblique sharp face along mouth of pipe direction, when tail washings outflow dropping liquid separation point is oblique sharp vertex of surface, liquid-solid contact face area is less, there is flow-guiding bar, destroyed liquid tension, more smooth and easy when tail washings drip returns in bottle, during in particular for the larger liquid of dress viscosity, advantage is more obvious.

The specific embodiment

The structure of the embodiment of the present invention, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5: a kind of Recovering bottle cover, comprises enclosing cover 7, inner cap, return port 6; The inner cap of compound sleeve tubulose is made up of inner tube 1 and outer tube 2, the middle part tube wall connecting sealed of inner tube 1 and outer tube 2, form an annular chamber annular, upper opening, the outer tube wall below of tubulose inner cap spins mutually with the mouth of bottle, in enclosing cover 7 is screwed in, cover, the bottom surface of annular chamber has return port 6 and is connected with bottle; The bottom surface that the inner tube 1 of inner cap is extended annular chamber is stretched in bottleneck, between the transverse plane that inner tube 1 is stretched out and tubular axis, there is the angle of one 45 degree, can certainly be that 30 degree, 60 degree are equal angular, be an oblique sharp face 5 along mouth of pipe direction, there is flow-guiding bar along return port to oblique sharp face tip, the flame diversion trough 4 that is provided with one axial groove shape at the tiltedly sharp pinnacle place of flushing is connected with return port 6, the tail washings diversed pinnacle to oblique sharp face 5 quickly that the setting of flame diversion trough 4 can make return port 6 flow down.

Inside pipe wall part on the bottom surface of annular chamber connects return port 6 places and is provided with axial breach straight pipe interruption-forming backflow notch 3 one, like this, has been equivalent to expand the aperture of return port 6, can be more smooth and easy when tail washings amount is large.

As flexible realization of the present invention, can also be in inner cap stretches to bottleneck 1 mouthful of place of inner tube of part dropping liquid separation point when a pointed entity in bottleneck is separately set flows out as tail washings, can reach equally while separation liquid-solid contact face area less, object more smoothly when tail washings drip returns in bottle; Within such conversion all drops on protection scope of the present invention.
