An anti-drip bottle cap and its anti-drip method

Abstract

The invention discloses an anti-drip bottle cap and an anti-drip method thereof. The bottle cap comprises a connected cover body and an upper cover, a diversion tube is arranged in the middle of the cover body, the upper part of the diversion tube is a diversion nozzle, and the diversion nozzle is inclined Setting; the bottom of the diversion pipe is provided with a return part, the outer peripheral edge of the return part is connected with the inner wall of the diversion pipe, the middle part of the return part is provided with an opening, and one end of the opening is located below the diversion nozzle. Its anti-drip method is to use the depth difference between the inner mouth end and the return end of the opening to quickly flow out from the inner mouth end; The trajectory forms a nice, smooth curve; after the product is poured out, most of the product flows back quickly from the inner spout, and the remaining product flows back along the entire curved surface of the return section. The invention can effectively improve the smoothness of liquid discharge and liquid collection when pouring oil, and fundamentally avoid the occurrence of oil leakage or oil dripping.

Description

technical field [0001] The invention relates to the technical field of seasoning packaging, in particular to an anti-drip bottle cap and an anti-drip method thereof. Background technique [0002] The commonly used liquid condiments on the market (such as various edible oils, soy sauce, etc.) are generally packaged in the form of a combination of glass bottles and plastic bottle caps. In the cap structure of pumping packaging bottles, due to the high viscosity of the product, the following phenomena generally exist during the pouring process of the product: [0003] (1) Since the oil guide port of the cover generally adopts a straight cylindrical structure, the liquid discharge and liquid collection are not smooth enough when pouring oil, and oil dripping or oil leakage is prone to occur; [0004] (2) Due to the small height difference between the diversion port and its peripheral fixed boss, parabolic interference is likely to occur when pouring oil, which affects the oil d...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the oil guide port of the cover generally adopts a straight cylindrical structure, the liquid discharge and liquid collection are not smooth enough when pouring oil, and oil dripping or oil leakage is prone to occur;

[0004] (2) Due to the small height difference between the diversion port and its peripheral fixed boss, parabolic interference is likely to occur when pouring oil, which affects the oil discharge speed, and it is also easy to cause oil droplets to adhere to the fixed boss;

[0005] (3) Since the inner mouth part of the cover is generally a planar structure, the opening is generally a long strip with uniform width or a special shape with a wide front and a narrow rear. Turbulent flow due to too fast operation during oil pouring, resulting in product splashing

[0006] (4) Since the inner side of the upper cover is a plane structure, when the packaging bottle is turned over or turned upside down, oil droplets enter the inner side of the upper cover, and when the cover is reopened in a short time, the residual oil droplets inside the cover will fall into the hinge along the inner wall of the cover The nearby area (that is, the connection between the upper cover and the cover body), thereby contaminating the outside of the bottle cap, causing greasy hands of the user and poor user experience
