Abstract

The utility model relates to an overflow-resistant automatic back-flow container cap, which solves the key point that the utility model improves ordinary container caps. The utility model is characterized in that an outflow pipe (1) and a back-flow pipe (4) are additionally arranged on an ordinary container cap so that liquid flowing on the outer wall of the outflow pipe (1) flows into an oblique concave surface slot along the outer wall of the outflow pipe (1) after liquid is stopped pouring, and the liquid flowing into the oblique concave surface slot flows into the container via the back-flow pipe (4) with a movable pellet (2) at the inner part; therefore, the utility model can prevent liquids, especially volatile liquids, toxic liquids, and corrosive liquids from polluting environment, and can prevent the outer wall of a container from liquid dirt; the function of the pellet (2) is that the pellet (2) tightly blocks a back-flow mouth (6) when liquid is poured out, and moreover, the pellet (2) is pressed off the back-flow mouth (6) by the external air pressure of a container when the internal air pressure of the container is reduced; therefore, the outflow velocity of the liquid is stable.

Description

The automatic reflux vessel lid of anti-overflow

When the utility model relates to a kind of pouring liquid, can remaining liquid around the wall of container and cause the lid that container whole body outer wall liquid dirt depends on.

The container cover outside of common carrying liquid is circular, perhaps the beaker degree of lip-rounding.No matter be circular, the still beaker degree of lip-rounding is unfavorable for that all the liquid that remains in container outer wall after liquid batch is toppled over collects in the container again, produces or test and make troubles for life.

A kind of ball float check double aperture seal anti-fake bottle stopper that Chinese patent application ZL96238207.8 proposes has only solved the liquid pouring problem that has some setbacks, but without eliminating container outer wall liquid dirt problem.

The purpose of this utility model just provides a kind of improved container cover, it remains in the outer liquid of vessel port and causes the liquid dirt along the container outer wall overflow in the time of preventing pouring liquid effectively, especially can reduce volatility widely, poisonous and corrosive liquid remains in outside the container, environment is polluted.

The purpose of this utility model is achieved in that

Assign two short tubes on container cover: a pipe end aligns with the container cover inwall, and head end outwards (is called for short the outflow pipe); Another root pipe head end aligns with the container cover outer wall, and is terminal in container (be called for short counter flow pipe, the pipe head end claims the mouth that refluxes).The outflow pipe is positioned at the container cover center, the adjacent outflow pipe configuration of counter flow pipe.Counter flow pipe head end portion and outflow pipe be terminal, and to be made into leaning angle be 30 °-50 ° oblique concave groove and communicate with each other.The built-in bead of counter flow pipe, little ball diameter should be slightly less than the counter flow pipe internal diameter, greater than backflow mouth internal diameter.The terminal arrangement of counter flow pipe stopped up band, falls in the container to avoid bead.Bead in the counter flow pipe is just in time blocked the backflow mouth when pouring out liquid.Along with the outflow of liquid in container, when the container internal gas pressure reduced, barometric pressure pushed away the backflow mouth to bead automatically, and counter flow pipe becomes at air inlet pipe, had both avoided liquid to flow out by the backflow mouth through counter flow pipe, guaranteed the smooth and easy outflow of liquid in container again.

The utility model is paid attention to unlikely scattering on container outer wall between container dress liquid used life, help keeping the container outer wall health, help avoiding environmental pollution, its structure is compared with general container cover, only need change a bed die a little, disposable the processing of raw material got final product.

Concrete structure of the present utility model is provided by following example and accompanying drawing thereof.

Figure (1) is the section-drawing according to the automatic return channel lid of the anti-overflow that the utility model proposes.

Figure (2) is the birds-eye view of the automatic reflux vessel lid of anti-overflow.

Figure (3) is a cap section-drawing on the container cover.

Describe details concrete in kind and the service condition that provides according to the utility model in detail below in conjunction with figure (1), figure (2).

This container cover comprises main body [5], and there are outflow pipe [1] and a counter flow pipe [4] in lid main body central upper portion place.Liquid flows out through pipe [1] during pouring liquid.Bead [2] in the pipe [4] is just in time blocked backflow mouth [6], and under the bar pressure effect, bead [2] can leave backflow mouth [6] automatically, in the air admission container, has guaranteed that liquid is smooth and easy.After stopping pouring liquid, bead is fallen counter flow pipe [4] bottom because backflow mouth [6] is left in action of gravity, blocks by stopping up band [7], can not fall in the container.It is in 30 ° of-50 ° of oblique concave groove [3] that the liquid that outflow ozzle [1] is remaining on every side can flow into leaning angle along the outer wall of outflow pipe [1], and then raffinate flows back in the container along backflow mouth [6] again.Stop to incline behind the liquid, cover on (1) and will scheme (3).

Claims

1, container cover that can the continuity pouring liquid, this container is stamped outflow pipe [1] and a counter flow pipe [4], the two adjoint oblique concave groove [3] that has an acceleration to reflux, the bead [2] that liquid overflows from counter flow pipe when preventing to topple over one is characterized in that outflow pipe [1] and counter flow pipe [4] are in the oblique concave groove [3] together.

2, according to claim 1, described container cover, it is characterized in that bead [2] in counter flow pipe [4], the diameter of bead [2] should be slightly less than the internal diameter of counter flow pipe [4], and greater than backflow mouth [6] internal diameter, the terminal arrangement of counter flow pipe [4] stopped up band [7].

3, according to claim 1, described container cover, it is characterized in that the bottom of oblique concave groove [3] communicates with backflow mouth [6], tiltedly the leaning angle of concave groove should be 30 °-50 °.
