Description

Technical Field

[0001] The utility model particularly relates to a self-sealing bottle cap which is easy to assemble. Background Art

[0002] A bottle used to store fluid or semi-fluid such as cream, ketchup, etc. is generally provided with a self-sealing bottle cap, which is usually provided with a soft rubber stopper sheet. The rubber stopper sheet is provided with extrusion holes or slits. When the bottle is squeezed, the rubber stopper sheet bulges due to the air pressure and the extrusion of the material in the bottle, and the holes or slits can be slightly opened, so that the material in the bottle can be squeezed out. Therefore, the rubber stopper sheet is generally made of soft plastic or soft silicone, and the self-sealing bottle cap needs to maintain sufficient mechanical strength. Therefore, the bottom cover is usually made of hard plastic. In the production process, the rubber stopper sheet and the bottom cover are first made separately, and then the rubber stopper sheet is installed on the bottle cap by assembly equipment or manual operation. For this structure, reference can be made to the patent with application number CN202122675578.5 and name of a new type of bottle cap previously applied by the inventor. The above-mentioned traditional self-sealing bottle cap needs to assemble the rubber plug sheet and the bottom cover. After the rubber plug sheet is installed on the bottom cover, a fastener needs to be installed on the rubber plug sheet. The fastener is connected to the bottom cover and then the fastener presses the rubber plug sheet onto the bottom cover. However, the assembly process is time-consuming and the fastener needs to be produced separately, which increases material consumption and reduces product production efficiency.
