Abstract

The utility model relates to a flowing-in anti-ovrflow bottle cover. An upper cylinder and a lower cylinder are connected into integration, male screw threads are arranged at the upper cylinder, and female screw threads are arranged at the lower cylinder; the inner part of the upper cylinder has another cylinder, the top end of the cylinder in the upper cylinder extends outwardly to form a convex side, the bottom part of the cylinder in the upper cylinder has a hole, and the right part of the hole is provided with a backflow hole; an overflowing ring groove is formed between the two cylinders at the upper part, and excess residual liquid are flown into the bottle from the overflowing ring groove and the backflow hole; when the utility model is used, the liquid can be prevented from being overflown, and the utility model is hygeian and can decrease waste.

Description

Reverse-flow type anti-overflow bottle cap

The utility model relates to a kind of reverse-flow type anti-overflow bottle cap, belongs to the technical field of parts of bottle type container.

Existing bottle cap mostly is a crown cap, and inner chamber is lined with a rubber pad, and sector is arranged around the bottle cap, the bottle cap of beer pop bottle for example uses the back bottle cap no longer can reuse, also has bottleneck to obturage with stopper, the outside bottle cap utilizes screw thread to be fixed on above the screw thread of bottleneck, and this bottle during liquid, often makes bottleneck that excessive residual liquid is arranged in toppling over bottle, hinder health, some bottle cap, for example oil bottle, soy cruet, vinegar bottle all can not be eliminated this flooded conditions, demands urgently improving.

The purpose of this utility model is that a kind of reverse-flow type anti-overflow bottle cap will be provided, and it can eliminate the shortcoming of overflow raffinate, and bottle cap is provided with double welt and return port, can prevent overflow, and promptly health can cut the waste again.

The purpose of this utility model is achieved in that

A kind of reverse-flow type anti-overflow bottle cap, its bottle cap top cylinder (1) has external screw thread (3), the lower cylindrical body also has negative thread (4), (5) are arranged between cylinder is connected up and down-annular groove, an incomplete cylinder (6) is arranged in the upper cylinder (1) in addition, and it highly surpasses cylinder (1), the top chimb (7) that stretches out, one circular hole (8) is arranged at cylinder (6) bottom, and its right side is discharge orifice (9) once in addition.

Fig. 1 anti-overflow bottle cap scheme drawing;

Fig. 2 anti-overflow bottle cap birds-eye view;

Fig. 3 anti-overflow bottle scheme drawing;

Fig. 4 enclosing cover scheme drawing.

Now in conjunction with the accompanying drawings the structure of reverse-flow type anti-overflow bottle cap is described in detail:

By Fig. 1,2, bottle cap top is a cylinder (1), the bottom is the big slightly cylinder of a diameter (2), cylinder (1) has external screw thread (3), cylinder (2) also has negative thread (4), one annular groove (5) is arranged between the cylinder (1) (2) up and down, one incomplete cylinder (6) is arranged in the upper cylinder (1) in addition, it highly surpasses cylinder (1), this cylinder (6) top is outward extended with a chimb (7), and cylinder (6) is in the accentric position, and the bottom has a circular hole (8) to be used for flowing out a liquid in the bottle, its right side has the less fuel return hole of a diameter (9) in addition, forms an overflow circular groove (13) between two cylinders in top (1) (6).

During use, unnecessary raffinate can flow back in the bottle from fuel return hole (9), and raffinate more also can (8) return in the bottle from the hole, has solved waste and insalubrious shortcoming.

By Fig. 3,4, the upper cylinder of bottle cap (1) is not provided with external screw thread, and in upper edge one annular ridge (10) is set.

One annular groove (12) is arranged at the inner chamber bottom of enclosing cover (11), and when enclosing cover (11) was sleeved on the bottle cap, fin (10) just in time was entrenched in the annular groove (12).

Compared with prior art, flowing-in anti-ovrflow bottle cover has following advantages:

1, in the bottle upper part of the cover inner chamber cylinder is arranged in addition, it is one little that its bottom has a circular hole, right side to have in addition Return port, make excessive liquid from then on orifice flow return in the bottle, namely health can cut the waste again.

2, bottle cap can cooperate fitted seal tight with existing bottle.

Claims

1, a kind of reverse-flow type anti-overflow bottle cap, it is characterized in that bottle cap top cylinder (1) has external screw thread (3), the lower cylindrical body also has negative thread (4), (5) are arranged between cylinder is connected up and down-annular groove, an incomplete cylinder (6) is arranged in the upper cylinder (1) in addition, and it highly surpasses cylinder (1), the top chimb (7) that stretches out, one circular hole (8) is arranged at cylinder (6) bottom, and its right side is discharge orifice (9) once in addition.
