Anti-dripping bottle cap and anti-dripping method thereof

Abstract

The invention discloses an anti-dripping bottle cap and an anti-dripping method thereof. The bottle cap comprises a cap body and an upper cap which are connected with each other, a guiding pipe is arranged in the middle of the cap body, the upper part of the guiding pipe is a guiding nozzle, and the guiding nozzle is inclined; a reflux part is arranged at the bottom of the guiding pipe, the peripheral edge of the reflux part is connected with the inner wall of the guiding pipe, an opening is formed in the middle of the reflux part, and one end of the opening is located on the lower part of theguiding nozzle. The anti-dripping method comprises the steps that firstly a product flows out from the inner nozzle end quickly by using the different depths of the inner nozzle end and the reflux end on the opening; then the product is poured out from the guiding nozzle, and by using the inclined setting of the guiding nozzle, a good and smooth curve is formed by a trajectory of the product during pouring; and after the product is poured out, most of the product is refluxed quickly from the inner nozzle end, and the residual product is refluxed along the curved surface of the whole reflux part. According to the anti-dripping bottle cap and the anti-dripping method thereof, the smoothness of liquid output and liquid collection during oil pouring can be effectively improved, and the occurrence of oil leakage or oil dripping is fundamentally avoided.

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
