CN2260065Y - Mouth of vessel with dirt preventing and drip-preventing means - Google Patents

Abstract

The utility model relates to a mouth of a vessel provided with a dirt preventing and a drip-preventing means. The utility model is characterized in that an outer casing, an inner core are mutually matched with a spring; the outer casing and the inner core form barrel shapes; the longitudinal section of the outer casing approximately forms a shape like the Chinese character 'ao'; the lower end of the inner core is outwards folded, and the inner core forms a platform shape; besides contact face of a platform of the inner core and the turnover part of the inner wall of the outer casing, the contact face of the outer casing and the inner core is provided with a liquid return tank, so that after liquid is poured, overflowing liquid flows in a cone-shaped tank at the inner side of the upper end of the outer casing along an outer wall of the inner core of the mouth of the vessel. When a vessel cap is closed, the inner core downwards presses (the spring is also pressed), and the liquid flows in the vessel along the liquid return tank. The utility model can prevent storing liquid from polluting a wall of the bottle and prevent leakage and loss.

Description

Antifouling, leakproof vessel mouth

The utility model belongs to a kind of plug type container mouth, thus vessel mouth that can antifouling leakproof when particularly a kind of bottleneck that inserts contain fluid or Hu Kou use.

In industrial and agricultural production and in the scientific experiment, often to come into contacts with the container that toxicity, corrosive liquid are housed, during use, after just putting containers such as bottle or kettles behind the pouring liquid, always a little liquid becomes bottle neck past dirty along its outside from Hu Zui, for avoiding polluting and cause the staff to contact poisoning, often need in time be removed.Also there is analogue when in people's daily life, using seasonings, when especially using oil bottle or oil can,, a small amount of oil edge bottle outer wall always arranged after the use, cause bottle outer wall to pollute, also cause waste to dirty because oily viscosity is bigger.

The utility model purpose is to provide a kind of antifouling, leakproof vessel mouth, can insert various liquid bottlenecks or Hu Kou and reach antifouling leakproof when using.

For reaching above-mentioned purpose, the utility model adopts following technical proposals: antifouling leakproof vessel mouth, it is made of shell, inner core and spring, shell and inner core are tubular, and the shell vertical section is approximate to be convex shape, and folding is platform-like outside the inner core lower end, shell and inner core slip and touch, the spring upper end joins with inner core, and the lower end is connected with outer casing inner wall, except that inner core platform and shell turnover position contact surface liquid return trough is arranged on shell and the inner core contact surface.

Interior outer core platform has liquid return trough with the upper part, and inner core lower platform outer rim has liquid return trough.

The outer casing inner wall turnover has liquid return trough more than the position, and inner core lower platform outer rim has liquid return trough.

Except that pressing to touch the part liquid return trough is arranged on the outer casing inner wall with inner core platform upper surface.

The shell upper outer rim has boss, and inboard, shell upper end is the approximate conical surface, and screw thread is arranged at outer shell outer wall top.

The utility model adopts inner core, shell, the spring three cooperatively interacts and the design of liquid return trough is set except that inner core platform and outer casing inner wall return portion contact surface on shell and inner core contact surface, simple in structure, the design of screw thread makes the utility model and container finish closely cooperate on outer rim flat-bed design of shell upper end and the outer shell outer wall, is difficult for falling into internal tank.When opening the container cover pouring liquid, spring is upheld, and inner core lower platform and shell turning point fit tightly, and liquid only flows out from the inner core mesopore.; overflow liquid flows in the liquid return trough (liquid return trough is changeable) along outer core in the bottleneck, and inner core presses down (spring also by compression) behind the bottle cap that closes, and liquid flows in the bottle along liquid return trough on inner core platform outer rim or the outer casing inner wall in the liquid return trough; both prevented to pollute, prevented leakage loss again.

Fig. 4 is the C-C cutaway view of Fig. 1.

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Embodiment, in the present embodiment, antifouling leakproof vessel mouth is by shell 1, inner core 2, constitute with spring 3, shell and inner core are tubular, and the shell vertical section is approximate to be convex shape, and folding is platform-like outside the inner core lower end, shell 1 slips with inner core 2 and touches, spring 3 upper ends and inner core 2 lower ends are pressed and are touched, and lower end and shell 1 lower inner wall upper support platform 4 are pressed and touched, and spring should guarantee to make inner core 2 lower platform, 5 upper surfaces and the fully closely pressing of shell turnover face when it opens.On inner core 2 outer walls, platform 5 has liquid return trough 6 with the upper part, inner core 2 lower platform have liquid return trough 7 on 5 edges.Shell upper end inboard 8 is the approximate conical surface, and shell upper end outer rim has platform 9, and this platform guarantees unlikely in use the falling in the liquid holding bottle of antifouling leakproof vessel mouth.
