CN203473493U - Anti-overflow bottle cap capable of causing residual liquid of bottleneck to be minimized and inwards flow - Google Patents

Abstract

The utility model discloses an anti-overflow bottle cap capable of causing residual liquid of a bottleneck to be minimized and inwards flow. The anti-overflow bottle cap comprises an upper cap (2) and a lower cap (1), which are connected through a screw thread. The lower cap (1) is characterized in that a lower part (1-1) of the lower cap is connected to a bottle body, an upper part (1-2) of the lower cap is provided with an external thread and is connected to the upper cap (2), a guide surface (1-3) is a slope and is convenient for the residual liquid to downwards flow into the bottle, a section used for pouring the liquid is a V-shaped guide groove (1-4), so that the residual liquid is minimized, a pull ring (1-5) is located at the tip of an irregular diamond shaped pull crack mouth, the labor is saved during tension fracture, and the anti-overflow bottle cap has the advantages of reasonable structure and convenience for use.

Description

A kind of anti-overflow bottle cap that makes the minimum and interior stream of bottleneck raffinate

Technical field:

The utility model relates to a kind of bottle cap, especially a kind of anti-overflow plastic bottle closure.

Technical background:

Common bottleneck is after pouring liquid, bottleneck has residual liquid unavoidably, although existing anti-overflow plastic bottle closure, substantially solved excessively, but its structure is not also quite reasonable, and its residual liquid guide face is level, can cause residual drop original place to be gathered, well, in interior stream bottle, also having the flame diversion trough Cross section Design of pouring liquid is that circular arc neither be quite reasonable, can not accomplish that raffinate minimizes.

Utility model content:

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide after a kind of pouring liquid not only bottleneck not have liquid remainder from flowing out of bottle, and residual liquid is minimized, and can on the guide face tilting, automatically flow back to a kind of anti-overflow bottle cap that makes bottleneck raffinate minimum and interior stream in bottle.

The purpose of this utility model can reach by following measure: a kind of anti-overflow bottle cap that makes bottleneck raffinate minimum and interior stream, it is comprised of upper cover and lower cover, lower cover comprises bottom and top, it is characterized in that lower cover bottom is connected with bottle, lower cover top is threaded with upper cover, upper cover upper inner, is provided with the guide face of inclination and the flame diversion trough that cross section is V-type, and the epistome of falling oil groove is sharp.The guide face of flame diversion trough inner side is provided with irregular rhombus drawing crack mouth and is connected with draw ring.

The utility model can produce following good effect compared with the prior art: 1, during pouring liquid, flowing through cross section is V-type flame diversion trough, and the tip of V-type groove can guarantee that residual liquid minimizes, and has guaranteed that liquid does not outflow to pollute outer bottleneck simultaneously.2, residual liquid flows to after guide face the breach that can be under Action of Gravity Field flows to lowest part along the guide face tilting and enters in bottle, can on guide face, not gather air-dryly, pollutes guide face.3, adopt 3 common constant worm pich to connect, structure is simpler.

Accompanying drawing explanation:

Fig. 1 is appearance assumption diagram of the present utility model;

Fig. 2 is the section-drawing before the utility model lower cover draw ring pulls off;

Fig. 3 is the section-drawing after the utility model lower cover draw ring pulls off;

Fig. 4 is the birds-eye view before the utility model lower cover draw ring pulls off;

Fig. 5 is the birds-eye view after the utility model lower cover draw ring pulls off.

The specific embodiment: embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:

A kind of anti-overflow bottle cap that makes the minimum and interior stream of bottleneck raffinate, by upper cover 2 and lower cover 1, formed, lower cover 1 comprises that lower cover bottom 1-1 is connected by pressure with bottle, according to the different seal ring of bottling liquid different choice, put in 1-1 inner groovy, lower cover top 1-2 is that 3 equidistant outside threads are connected with upper cover negative thread, 1-2 inner side is provided with the guide face 1-3 of inclination, the gravity reflux of raffinate dependence own is entered in bottle to minimum breach place, it is V-type flame diversion trough 1-4 that guide face is provided with cross section, the tip outlet of flame diversion trough can guarantee minimum residual liquid, the guide face of flame diversion trough inner side is provided with irregular rhombus drawing crack mouth and is connected with draw ring 1-5, draw ring is connected with place, rhombus tip, more laborsaving when pulling open, such anti-overflow bottle cap just can make the minimum and interior stream of bottleneck raffinate.

Claims (1)

1. an anti-overflow bottle cap that makes the minimum and interior stream of bottleneck raffinate, it is comprised of upper cover (2) and lower cover (1), lower cover (1) forms by (1-1) with (1-2), it is characterized in that lower cover bottom (1-1) is connected with bottle with pressure, lower cover top (1-2) is connected with 3 constant worm pich with upper cover (2), raffinate guide face (1-3) inclined design, the flame diversion trough of pouring liquid (1-4) Cross section Design is V-type, and the raffinate guide face of flame diversion trough inner side is provided with irregular rhombus drawing crack face and is connected with draw ring (1-5).
