Abstract

The utility model a bottle nozzle for a liquid reservoir. The bottle nozzle for a liquid reservoir is provided with a pipe which can pass through liquid. The upper part of the pipe is bended into an obtuse angle. The head cross section of the pipe and the pipe are made into an acute angle. The apex of the acute angle is positioned on the top end of the pipe. As the selection of the break angle and the exit angle of the pipe make full use of the coanda effect and the negative pressure of liquid, the bottle nozzle for a liquid reservoir can effectively prevent the liquid from flowing down along the appearance of the liquid reservoir to pollute the appearance of the liquid reservoir and a table top; as the object can be obtained that the pipe is provided with one break angle and one inclined exit, the utility model has the advantages of simple structure, low cost, and convenience.

Description

Bottle nozzle

The utility model relates to a kind of bottle neck of the tipper of storing liquid container, particularly a kind of recyclable surplus liquid.

Storage liquid container of the prior art usually has liquid and down trickles along the container appearance behind pouring liquid, pollutes container appearance and desktop, and is not only unhygienic but also waste liquid, causes a lot of inconvenience to people.

The purpose of this utility model is to provide a kind of bottle neck, and it can be installed on the various storage liquid containers, and in pouring liquid and front and back process thereof, prevents that effectively liquid from down trickling along the container appearance, pollutes container appearance and desktop.

The utility model is achieved in that a kind of bottle neck, particularly a kind of bottle neck of storing liquid container, this bottle neck have one can be by the pipe of liquid, the epimere of pipe with in intersegmentally be formed with a knuckle, the angle of this knuckle is between 110 °～130 °, and there is a fixed cap in the outside, the middle part of pipe, and pipe passes from this fixed cap, and with the fixed cap driving fit, exit, pipe upper end is a bevelled cross section.In the utility model front section vertically, this cross section and pipe epimere shape are in an angle, the summit of this angle is positioned at the top of tube wall, and the angle of this angle is between 40 °～50 °, and place, the summit of this angle is fluid mouth of the present utility model.During use, pipe is inserted container and utilizes fixed cap and seal of vessel, with container lean, make the position of fluid mouth be in minimum, liquid enters pipe, make-up gas immediately for the moment in the container, thereby container bottom formation negative pressure, liquid that can not flows out, when dump angle continues to increase, liquid gravity overcomes negative pressure and flows out, air enters container via pipe simultaneously, because the wall attachment effect of liquid, the tight attached tube wall of liquid flows out, because it is minimum that the position of fluid mouth is in, so liquid flows out from the fluid mouth.When container is put timing, liquid in container descends according to its action of gravity, and negative pressure is formed at container top, and surplus liquid depends on wall effect again in the pipe, and tube wall flows back in the container in the suction function lower edge.For increasing the sealing property of the utility model and container, outside the tube wall of pipe hypomere, also the seal ring that rubber or plastic material are made can be housed.

The utility model is because only need make pipe that a knuckle and a bevelled outlet are arranged, so structure is simple especially, simultaneously because the selection of the angle of pipe knuckle and outlet has made full use of the wall attachment effect and the negative pressure of liquid, down trickle along the container appearance so can prevent liquid effectively, pollute container appearance and desktop.The utility model is not found in the prior art as yet.

Fig. 1 is a structural representation of the present utility model.

Wherein, 1-pipe 2-fluid mouth 3-seal ring 4-fixed cap

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, a kind of bottle neck of the utility model, this bottle neck has a pipe 1 that can pass through liquid, the epimere of pipe 1 with in intersegmentally be formed with a knuckle, the angle of this knuckle is between 110 °～130 °, there is a fixed cap 4 in the outside, middle part of pipe 1, pipe 1 passes from this fixed cap 4, and with fixed cap 4 driving fits, exit, pipe 1 upper end is a bevelled cross section, in the utility model front section vertically, this cross section and pipe 1 epimere shape are in an angle, the summit of this angle is positioned at the top of tube wall, and the angle of this angle is between 40 °～50 °, and place, the summit of this angle is fluid mouth 2 of the present utility model.During use, pipe 1 is inserted container and utilizes fixed cap 2 and seal of vessel, with container lean, make the position of fluid mouth 2 be in minimum, liquid enters pipe 1, make-up gas immediately for the moment in the container, thereby container bottom formation negative pressure, liquid that can not flows out, when dump angle continues to increase, liquid gravity overcomes negative pressure and flows out, air enters container via pipe 1 simultaneously, because the wall attachment effect of liquid, the tight attached tube wall of liquid flows out, because it is minimum that the position of fluid mouth 2 is in, so liquid flows out from the fluid mouth.When container is put timing, liquid in container descends according to its action of gravity, and negative pressure is formed at container top, and surplus liquid depends on wall effect again in the pipe, and tube wall flows back in the container in the suction function lower edge.For increasing the sealing property of the utility model and container, the seal ring 3 that plastic material is made is housed outside the tube wall of pipe 1 hypomere.

Claims (3)

1, a kind of bottle neck, particularly a kind of bottle neck of storing liquid container, this bottle neck has a pipe 1 that can pass through liquid, it is characterized in that: the epimere of pipe 1 and centre are formed with a knuckle, the angle of this knuckle is between 110 °～130 °, and exit, pipe 1 upper end is a bevelled cross section, and this cross section and pipe 1 epimere shape are in an angle, the summit of this angle is positioned at the top of pipe 1 epimere tube wall, and the angle of this angle is between 40 °～50 °.

2, a kind of bottle neck as claimed in claim 1 is characterized in that: there is a fixed cap 4 in the outside of pipe 1, and pipe 1 passes from this fixed cap 4, and with fixed cap 4 driving fits.
