Abstract

The utility model discloses a reflux bottle cap which consists of an outer cap, an inner cap and a reflux hole. The tubular inner cap consists of an inner tube and an outer tube, and the central tube walls of the inner tube and the outer tube are connected and sealed to form an annular cavity with an opening on the upward side. The external tube wall of the tubular cap matches with a bottle beak, the bottom surface of the annular cavity is provided with a reflux hole communicated with the bottle body. The reflux bottle cap is characterized in that the inner tube of the inner cap extends out of the bottom surface of the annular cavity and extends into the bottle beak, a proper included angle is formed between a transverse plane extended by the inner tube and a tubular shaft, and a slanted plane is formed along the direction of a tube nozzle. As the inner tube of the inner cap extends out of the bottom surface of the annular cavity and extends into the bottle beak, a proper included angle is formed between the transverse plane extended by the inner tube and the tubular shaft, and a slanted plane is formed along the direction of the tube nozzle, the contact area of liquid and solid is comparatively smaller and the tail liquid can drop and flow back into the bottle more smoothly when the tail liquid flows out of the separation point of dropping liquid, i.e. the vertex of the slanted plane. When the reflux bottle cap is used for loading liquid with a comparatively large viscosity coefficient, more obvious advantages can be observed.

Description

A kind of Recovering bottle cover

Technical field

The utility model relates to a kind of bottle cap, relates in particular to a kind of Recovering bottle cover.

Background technology

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

As: Granted publication number in the Chinese patent of CN2419177Y a kind of backflow bottle cap is disclosed, it is made up of enclosing cover, inner cap, return port, the inner cap of composite bushing shape is made of interior pipe and outer tube, interior pipe is connected sealing with the middle part tube wall of outer tube, form an annular chamber annular, the top opening, the 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 liquid was poured out in the bottle, remaining in bottleneck liquid on every side can pass back in the bottle by the return port of inner cap annular chamber bottom surface.

Adopt such technology certainly to 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 on same plane, tail washings flow out return port when being the dropping liquid separation point liquid-solid mating surfaces long-pending bigger, smooth and easy inadequately when the tail washings drip returns in the bottle, during in particular for the bigger liquid of dress viscosity, more obvious.

The utility model content

For overcoming the deficiencies in the prior art, the utility model provides a kind of backflow dropping liquid separation point and inner cap annular chamber bottom surface not on same plane, and liquid-solid mating surfaces was long-pending less when tail washings flowed out the dropping liquid separation point, Recovering bottle cover more smoothly when the tail washings drip returns in the bottle.

The utility model is to overcome the above problems the technical scheme that is adopted to be: a kind of Recovering bottle cover comprises enclosing cover, inner cap, return port; The inner cap of composite bushing shape is made of interior pipe and outer tube, and the middle part tube wall of interior pipe and outer tube is connected sealing, forms an annular chamber annular, the top opening, and the 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 interior pipe of inner cap extends annular chamber is stretched in the bottleneck, and a suitable angle is arranged between transverse plane that interior pipe stretches out and tubular axis, is an oblique sharp face along mouth of pipe direction.

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

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

The beneficial effects of the utility model are: stretch in the bottleneck because the interior pipe of inner cap extends the bottom surface of annular chamber, a suitable angle is arranged between transverse plane that interior pipe stretches out and tubular axis, be an oblique sharp face along mouth of pipe direction, tail washings flows out the dropping liquid separation point when being oblique sharp vertex of surface, and liquid-solid mating surfaces is long-pending less, it is more smooth and easy when the tail washings drip returns in the bottle, during in particular for the bigger liquid of dress viscosity, advantage is more obvious.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Wherein:

Fig. 1 is the utility model example structure schematic perspective view;

Fig. 2 is the schematic perspective view of inner cap structure among the utility model embodiment;

Fig. 3 is the schematic perspective view of another angle of inner cap structure among the utility model embodiment;

Fig. 4 is the inner cap structure schematic perspective view of another angle again among the utility model embodiment;

Fig. 5 is that the inner cap structure is analysed schematic perspective view among the utility model embodiment.

The specific embodiment

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

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

As flexible realization the of the present utility model, can also be in inner cap stretches to bottleneck 1 mouthful of place of interior pipe of part dropping liquid separation point when a pointed entity in bottleneck being set in addition flowing out as tail washings, it is long-pending less to reach when separating liquid-solid mating surfaces equally, purpose more smoothly when the tail washings drip returns in the bottle; Such conversion all drops within the protection domain of the present utility model.
