Bottle cap preventing liquid overflowing from high-viscosity liquid storage bottle

Abstract

The invention provides a bottle cap preventing liquid overflowing from a high-viscosity liquid storage bottle. The bottle cap is sequentially provided with an upper screw cover, a sharp mouth pipe, an overflowing stopping ring and a lower screw cover from top to bottom. The lower screw cover is provided with a liquid fetching hole and connected with the storage bottle. The lower portion of the overflowing stopping ring is fixed to the lower screw cover, and the upper screw cover is arranged on the overflowing stopping ring in a screwed mode. A pipe seat is arranged on the lower portion of the sharp mouth pipe, and the pipe seat is rotationally arranged in a limiting groove of the upper end face of the lower screw cover in a sliding mode. The sharp mouth pipe protrudes out of a ring hole of the overflowing stopping ring, the outer wall of the sharp mouth pipe makes no contact with the ring hole, and an overflowing liquid temporary storage cavity is formed by the lower screw cover and the overflowing stopping ring in an enclosed mode. A liquid fetching channel of the bottle cap is a pipe cavity of the sharp mouth pipe, the upper half section of an overflowing liquid backflow channel of the bottle cap is composed of a plurality of pipe seat holes, the lower half section of the overflowing liquid backflow channel is composed of a plurality of screw cover holes, the pipe seat holes correspond to the screw cover holes, and when the pipe seat rotates, the overflow cross-sectional area of the overflowing liquid backflow channel changes. The lower end face of the overflowing liquid temporary storage cavity communicates with the overflowing liquid backflow channel. The bottle cap can effectively prevent the high-viscosity liquid from overflowing from the bottle when the liquid is taken for use.

Description

technical field [0001] The invention relates to the field of liquid storage, in particular to a bottle cap for preventing high-viscosity liquid storage bottles from overflowing. Background technique [0002] Some high-viscosity liquids such as honey, peanut oil and other oil storage bottles, during use, when the liquid is poured out, the liquid at the bottle mouth cannot return to the bottle in time due to high viscosity, but overflows from the bottle mouth. This part of the liquid will flow down along the wall of the bottle due to gravity. If this happens for a long time, the outer surface of the bottle will be covered with liquid, which will not only affect hygiene but also affect use. Therefore, most of the bottle caps currently on the market for holding high-viscosity liquids use pointed nozzle tube caps to reduce residues. However, this bottle cap does not essentially solve the problem of liquid spilling during pouring, and during long-term use, a large amount of spill...

Problems solved by technology

However, this bottle cap does not essentially solve the problem of liquid spillage during pouring. During long-term use, a large amount of spilled liquid will still remain on the outer surface of the storage bottle.
