Abstract
The utility model discloses a bottle cap, and particularly relates to a sports bottle cap. The sports bottle cap can improve reliability of seal between a pulling cap and a main cap. The sports bottle cap comprises an outer cap, the pulling cap and the main cap. The main cap comprises a connecting end and a sealing end, wherein the connecting end is provided with connecting threads, the sealing end is provided with a ring-shaped liquid outlet, the pulling cap is sleeved on the sealing end of the main cap and can axially move, the pulling cap is provided with a ring-shaped inner sealing face and a ring-shaped outer sealing face, the inner sealing face is matched with an inner ring-shaped face of the liquid outlet in a sealed mode, the outer sealing face is matched with an outer ring-shaped face of the liquid outlet in a sealed mode, the outer cap is connected with the main cap, the pulling cap is arranged inside the outer cap in a sleeved mode, and the outer sealing face of the pulling cap is provided with a ring-shaped protrusion. Due to the facts that the outer sealing face of the pulling cap is provided with the ring-shaped protrusion, and interference fit is adopted, not only can seal be ensured, but also moderate drawing force can be ensured. Due to the fact that the inner sealing face is a cone-shaped face, not only is assembly convenient, but also the drawing force can be adjusted.
Description
Technical field
The utility model relates to a kind of bottle cap, especially a kind of Sports bottle cap.
Background technology
Popular along with sport type beverage, Sports bottle cap also produces accordingly, it mainly comprises enclosing cover, draws lid and main lid, and the main liquid outlet that is provided with annular that covers draws to cover the liquid outlet that is provided with hermetically-sealed construction sealing annular, draw when covering when being pulled upwardly, hermetically-sealed construction breaks away from liquid outlet, and flow of liquid is gone out, when pressing drop-down lid, the outlet of hermetically-sealed construction seal fluid reaches the effect of closing.Enclosing cover is mainly used in protection and draws lid.The Sports bottle cap epoch is shorter, it is in use mainly by following shortcoming: mostly the user of Sports bottle cap is some sporters, the impact that Sports bottle cap is subjected in motion process is bigger, the sealing of drawing the Gai Yuzhu lid at present is to rely on two sealing planes to realize, under vigorous exercise, the effect of sealing plane is relatively poor, and loosening easily, causes leakage.
The utility model content
Technical problem to be solved in the utility model provides a kind of increase and draws lid and the main Sports bottle cap that covers sealing reliability.
The Sports bottle cap that its technical matters that solves the utility model adopts, comprise enclosing cover, draw lid and main lid, described main lid is divided into coupling end and capping end, described coupling end is provided with connecting thread, described capping end is provided with the liquid outlet of annular, but described capping end and the axial motion that draws lid to be set in described main lid, described inner sealing surface and the annular outer gland sealing face that is provided with annular that cover that draw, described inner sealing surface and outer gland sealing face are sealed and matched with the inner ring surface and the outer ring surface of described liquid outlet respectively, described enclosing cover is connected with described main lid and with described draw cover be set in, the described outer gland sealing face of lid that draws is provided with annular protrusion.
Further be that it is planar that the described inner sealing surface that draws lid is up-small and down-big taper.
Further be that described connecting thread is an interrupted screw-thread.
The beneficial effects of the utility model are: owing to draw the outer gland sealing face of lid to adopt annular projection and employing interference fit, can guarantee sealing, guarantee to have the pulling capacity of appropriateness again.Inner sealing surface is the conical surface simultaneously, and is both convenient for assembly, also can regulate the power of dialling of drawing.Adopt interrupted screw-thread can be suitable for high-voltage carbonic acid lid, be beneficial to when opening bottle cap and situation that screw thread is not outwarded winding fully under, get rid of a gas in the bottle earlier, avoid bottle cap in opening process, to eject suddenly and hurt the people, improved the safety in the use.

Parts, position and numbering among the figure: main cover 1, draw cover 2, enclosing cover 3, coupling end 11, capping end 12, liquid outlet 13, connecting thread 14, inner sealing surface 21, outer gland sealing face 22, annular protrusion 24.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises enclosing cover 3, draw and cover 2 and main cover 1, described master is covered 1 and is divided into coupling end 11 and capping end 12, described coupling end 11 is provided with connecting thread 14, described capping end 12 is provided with the liquid outlet 13 of annular, but described drawing covered 2 and is set in the described main also axial motion of 1 capping end 12 that cover, described drawing covered 2 and is provided with the inner sealing surface 21 of annular and the outer gland sealing face 22 of annular, described inner sealing surface 21 and outer gland sealing face 22 are sealed and matched with the inner ring surface and the outer ring surface of described liquid outlet 13 respectively, described enclosing cover 3 with described main cover 1 be connected and with described draw cover 2 be set in, described drawing covered 2 outer gland sealing face 22 and is provided with annular protrusion 24.In use, at first take off enclosing cover 3; Draw and cover 2 and be stuck in main the lid in 1 the recessed position of an end, draw like this and cover 2 and just can cover 1 and carry out the motion of a segment distance with respect to leading by the bossing on it.After taking off enclosing cover 3, upwards mention to draw and cover 2 one segment distances, make inner sealing surface 21 and outer gland sealing face 22 cooperate with the inner ring surface and the outer ring surface disengaging of liquid outlet 13 respectively, like this, liquid outlet 13 places just lose sealing, and liquid just can flow out from liquid outlet.Otherwise, when needs are closed bottle cap, by drop-down lid 2, make inner sealing surface 21 and outer gland sealing face 22 be sealed and matched with the inner ring surface and the outer ring surface of liquid outlet 13 respectively, thereby block liquid outlet 13, reach sealing effectiveness.Outer gland sealing face 22 has been set up annular protrusion 24, and makes annular protrusion 24 cover 1 outer ring surface interference fit with main, has both increased sealing reliability, has also guaranteed appropriate pulling capacity.Inner sealing surface 21 is a conical suface simultaneously, just is more prone to when assembling, and can also regulate pulling capacity by the angle of regulating conical suface.
Concrete, as shown in Figure 3, described connecting thread 14 is an interrupted screw-thread.Interrupted screw-thread can be suitable for high-voltage carbonic acid lid, and be beneficial to when opening bottle cap and situation that screw thread is not outwarded winding fully under, get rid of a gas in the bottle earlier, avoid bottle cap in opening process, to eject suddenly and hurt the people, improved the safety in the use.
