Problems solved by technology

First, during the assembly process of the bottle cap, when a set of threads matched by the cap body and the fitting body and a set of threads matched by the cap body and the bottom cap are respectively tightly engaged, the stop teeth of the bottom cap and the fitting body It is difficult to maintain a tight fit of the blocking teeth, which puts high demands on the precision of design and manufacturing in the industrial implementation process, and increases the complexity and difficulty of bottle cap assembly
Second, after the bottle cap is assembled, during the transportation and storage process before the product is used, the rotation error of the cap body may cause the sealing performance of a set of threads matched by the cap body and the bottom cap to be affected, thus affecting the product. quality reliability
Fourth, when using after the bottle cap is opened, since the aptamer remains in the opening of the bottle, it is easy to cause the contents of the bottle to not flow out and produce residues; It is not only inconvenient to operate, but also when the opening of the bottle is closed again, the contents of the bottle are easily polluted by the bottom cap
Fifth, the structure of the bottle cap is complex, and the design is difficult to produce a simplified solution in the industrial implementation process, which not only wastes materials in manufacturing, but also limits the industrial application of the design

Abstract

A dispensing cap includes a cap body (A), a bottom cover (B) and an adapting unit (C). The cap body (A) seals an opening part (9) of a sealed container (D), and includes a cylinder part (3) for accommodating materials (E) and an opening part (30) formed at the end of the cylinder part (3). The bottom cover (B) is connected threadedly to the opening part (30) of the cylinder part (3) hence to seal the latter, wherein the bottom cover (B) includes a skirt (4) and a bottom cover opening device (48). The bottom cover opening device (48) includes stop parts (41) formed on the skirt (4) of the bottom cover (B) and obstructing part (86) used for preventing the stop parts (41) from rotating when the bottom cover (B) is opened. The adapting unit (C) includes sealing parts (80), the obstructing parts (86) and elastic parts (83) on the circumference between the sealing parts (80) and the obstructing parts (86). The elastic parts (83) can ensure the tight engagement between the stop parts (41) and the obstructing parts (86) of the bottom cover opening device (48).

Description

technical field [0001] The present invention relates to a dispensing cap. Background technique [0002] In a bottle cap design solution disclosed in the patent document JP2009-126527A, the opening device of the bottom cap consists of a stopper part formed on the skirt part of the bottom cap and a blocking part formed on the peripheral edge of the end of the fitting body respectively, but The above-mentioned design scheme has the following defects. First, in the process of assembling the bottle cap, when the set of threads matched with the cap body and the fitting body and the set of threads matched with the cap body and the bottom cap are tightly meshed respectively, the stopper teeth of the bottom cap and the fitting body are in close contact with each other. It is difficult for the blocking teeth to keep a tight fit, which puts forward high requirements on the precision of design and manufacture in the industrial implementation process, and increases the complexity and di...
