Abstract
The utility model discloses an injection molding bottle cap with a good sealing effect. The injection molding bottle cap comprises a cap top and a peripheral wall integrated with the cap top, wherein the inner surface of the cap top is provided with an annular inner plug extending downwards, an annular bulge is arranged at the joint of the cap top and the peripheral wall on the inner surface of the bottle cap, and the bulge and the inner plug are respectively in interference fit with the outer wall and the inner wall of a bottle neck. By the annular bulge, a seal is added at the outer wall of the bottle neck, so that two layers of anti-leakage systems are formed to further improve the sealing performance of the bottle cap.
Description
Technical field
The utility model relates to bottle cap, relates in particular to the injection mo(u)lding bottle cap.
Background technology
Existing injection mo(u)lding bottle cap obtains sealing effectiveness through the interference fit of plug and bottleneck inwall in the bottle cap mostly.This bottle cap sealing effect is limited, is inappropriate for the inflatable beverage bottle.When sealing effectiveness can not meet the demands, way was the magnitude of interference that strengthens between interior plug of bottle cap and the bottleneck inwall usually.
The utility model content
The utility model technical matters to be solved provides a kind of injection mo(u)lding bottle cap of good sealing effect.
For this reason; The injection mo(u)lding bottle cap of the utility model comprise a caping and with the perisporium of this caping one; Has a plug in the annular that extends below on the inside face of said caping; The intersection that is positioned at its caping and perisporium on this bottle cap inside face has annular protrusion, this convexity and said in plug respectively with the outer wall and the inwall interference fit of bottleneck.Can increase place sealing at the outer wall place of bottleneck through annular protrusion, form two-layer leakproof system, thereby improve the leak tightness of bottle cap.
On the basis of technique scheme, also annular indent can be set on the sidewall that matches with said bottleneck on the said convexity.Can increase local pressure protruding and the bottleneck outer wall through annular indent, thereby further improve protruding leak tightness.In addition, convex to form back-off, help maintenance bottle cap torsion because annular indent makes.
In addition, can also the one section inside face that join with said convexity on the said caping be designed to towards protrusion direction bevelled inclined-plane from bottom to top.Like this, in the process of bottle cap of screwing, will form local big interference between the inside face of the top of bottleneck and bottle cap caping, and combine sealing protruding and the bottleneck outer wall again, thereby further improve the leak tightness of bottle cap.
A kind ofly in addition guarantee that protruding scheme with bottleneck outer wall leak tightness is an outer wall interference fit side of said convexity is whole and bottleneck, and this side is from top to bottom towards the bottle cap outer incline.This scheme can help the maintenance to bottle cap torsion equally.
In addition, the intersection that is positioned at its caping and perisporium on this bottle cap outside face has annular groove.It is to save the bottle cap material that this annular groove one is set; Reduce its productive costs; The 2nd, dwindle because of establishing the bottle cap wall thickness that annular protrusion increases in the intersection that on the bottle cap inside face, is positioned at its caping and perisporium, improve bottle cap single-piece evenness of wall thickness, guarantee the injection moulding quality.
Further, have many on the outside face of said perisporium along the circumferential spaced anti-slop serrations of bottle cap, these anti-slop serrations extend upward the upper surface to caping from the outside face of perisporium.Through the above-mentioned anti-slop serrations of setting up, improve feel, particularly, can guarantee skidproof effect preferably because these anti-slop serrations extend to the upper surface of caping always.
In sum, the injection mo(u)lding bottle cap of the utility model is compared existing bottle cap and is had better sealing effectiveness, is specially adapted to the inflatable beverage bottle.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1; The injection mo(u)lding bottle cap comprise a caping 1 and with the perisporium 2 of this caping 1 one; Has a plug 3 in the annular that extends below on the inside face of said caping 1; The inwall of plug 3 is provided with the cambered surface of outwards heaving, the inwall interference fit of this cambered surface and bottleneck 4 behind the bottle cap of screwing in being somebody's turn to do; The intersection that on the bottle cap inside face, is positioned at its caping 1 and perisporium 2 has annular protrusion 5, should convexity 5 behind the bottle cap of screwing and the outer wall interference fit of bottleneck 4.The surface of this convexity 5 is smooth arc, is worn in the time of can avoiding repeated use like this and causes sealing effectiveness to descend.Has annular indent 6 on protruding 5 with on the sidewall that said bottleneck 4 matches; Like this; Protruding 5 have just formed the structure of a back-off shape, can either increase the round end of convexity 5 and the pressure between the bottleneck outer wall, thereby further improve protruding 5 leak tightness; And, help maintenance to bottle cap torsion because the structure of this back-off shape puts on 4 one gripping powers of bottleneck.In addition; The intersection that is positioned at its caping 1 and perisporium 2 on this bottle cap outside face has annular groove 7; The one, the material usage in the time of can reducing injection moulding reduces the bottle cap productive costs, and the 2nd, can dwindle because of on the bottle cap inside face, being positioned at its caping 1 and establish the bottle cap wall thickness that annular protrusion 5 increases with the intersection of perisporium 2; Improve bottle cap single-piece evenness of wall thickness, guarantee the injection moulding quality.Moreover the feel when rotating bottle cap for improving and the effect of exerting oneself have many along the circumferential spaced anti-slop serrations 8 of bottle cap on the outside face of said perisporium 2, and these anti-slop serrations 8 extend upward to the upper surface of caping 1 from the outside face of perisporium 2.
Injection mo(u)lding bottle cap as shown in Figure 2; This bottle cap and the key distinction of bottle cap shown in Figure 1 are it and do not establish annular indent 6 on protruding 5 with on the sidewall that bottleneck 4 matches; But, be towards protruding 5 directions bevelled inclined-plane from bottom to top, in the process of bottle cap of screwing with protruding 5 one section inside face 9 joining on its caping 1; To form local big interference near the position of interior plug 3 at bottleneck 4 tops between the inside face of the top of bottleneck 4 and bottle cap caping 1; Like this, be equivalent on the basis of interior plug 3, protruding 5, to have increased by a place again and effectively seal, thus the leak tightness of raising bottle cap.Certainly, above-mentioned with on the caping 1 with protruding 5 one section inside face 9 joining be designed to towards protruding 5 directions from bottom to top the technological means on bevelled inclined-plane also can directly be applied on the bottle cap shown in Figure 1 or shown in Figure 3.
Injection mo(u)lding bottle cap as shown in Figure 3, its protruding 5 a side 10 integral body and the outer wall interference fit of bottleneck 4, and this side 10 is from top to bottom towards the bottle cap outer incline.Than bottle cap shown in Figure 2, cooperate area bigger between the side 10 of the bottle cap of Fig. 3 and its bottleneck 4 outer walls, therefore more help maintenance to bottle cap torsion.Because the convexity 5 of the bottle cap of Fig. 3 is thicker, therefore, the intersection that is positioned at its caping 1 and perisporium 2 on this bottle cap outside face still has annular groove 7.In addition, on the outside face of its perisporium 2, have many along the circumferential spaced anti-slop serrations 8 of bottle cap, these anti-slop serrations 8 extend upward to the upper surface of caping 1 from the outside face of perisporium 2.
