Abstract

The utility model discloses a bottle mouth used for a container containing liquid, comprising a bottle mouth bottom seat. The bottle mouth bottom seat is provided with a liquid pouring opening, and a liquid return hole is arranged beside the liquid pouring opening; the liquid pouring opening has an interlayer structure, and the liquid return hole is arranged in the interlayer structure; for example, when the liquid pouring opening is composed of an inner sheath and an outer sheath, the liquid return hole is arranged between the inner sheath and the outer sheath. The liquid can be led into the container containing the liquid through utility model, and accordingly, the outflow of the liquid on the bottle mouth is effectively prevented; the pollution is reduced.

Description

Bottleneck
The utility model relates to a kind of bottleneck that uses on liquid filling container, especially relate to a kind of bottleneck that uses on the dense thick liquid container of splendid attire.
Present bottleneck is after using on the container, and when outside pouring liquid, partially liq can flow to the outside of container along bottleneck, and is dirty along the bottleneck outer wall, and the container of both having made dirty has caused waste again.
Goal of the invention of the present utility model is to provide a kind of bottleneck that pollutes liquid filling container that reduces.
The utility model adopts following technical scheme to realize its goal of the invention:
The utility model is a kind of bottleneck that uses on liquid filling container, comprises the bottleneck base, is provided with filtering port on the bottleneck base, at the other hole for back flow that is provided with of filtering port.
Compared with prior art, the utlity model has following advantage:
1. because the utility model is provided with hole for back flow, so it can make the container of part along the dirty liquid inflow carrying liquid of bottleneck, stretches to the liquid of liquid filling container outer wall thereby reduced along the bottleneck outer wall, the outer wall that has reduced container, bottleneck pollutes, and has realized goal of the invention.
2. when filtering port employing sandwich structure, hole for back flow is located in the interlayer, when particularly filtering port adopts inside and outside nested structure, is in bottleneck and the liquid that outflows can flow into interlayer and flow back to container by hole for back flow, thereby more effectively stoped the liquid outflow, further reduced pollution.
Fig. 1 is the structural representation of the utility model embodiment.
With reference to the accompanying drawings, embodiment of the present utility model being done one describes in detail:
The utility model is a kind of bottleneck that uses on liquid filling container, comprise bottleneck base 1, on bottleneck base 1, be provided with filtering port 2, at the filtering port 2 other hole for back flow 3 that are provided with, filtering port 2 is a sandwich structure, hole for back flow 3 is located in the interlayer, for example: filtering port 2 is made up of interior cover 21 and overcoat 22, and cover 21 and overcoat were 22 in hole for back flow 3 was located at.

Claims (3)

1. a bottleneck that uses on liquid filling container comprises bottleneck base (1), is provided with filtering port (2) on bottleneck base (1), it is characterized in that at the other hole for back flow (3) that is provided with of filtering port (2).
2. bottleneck according to claim 1 is characterized in that filtering port (2) is sandwich structure, and hole for back flow (3) is located in the interlayer.
3. bottleneck according to claim 2 is characterized in that filtering port (2) is made up of interior cover (21) and overcoat (22), and hole for back flow (3) is located between interior cover (21) and the overcoat (22).
