Description

Technical Field

[0001] The utility model specifically relates to a bottle cap with a self-sealing structure and a safety structure. Background Art

[0002] Bottles used to store fluids or semi-fluids such as peanut oil are generally provided with bottle caps, which are connected and sealed by spiral patterns. In order to ensure good sealing of the product before use, the bottle caps are generally provided with safety caps, which need to be removed before use. For reference, patent application number CN201621176447.5, entitled "A New Bottle Cap for Barreled Edible Oil", can be used. However, once the safety cap is removed, the liquid in the bottle will be poured out from the opening on the bottle cap. However, when the safety cap is removed, the bottle is in an open state during use, and the opening of the bottle cap is generally large, especially the cover of the oil bottle. Since the opening of the bottle cap is not sealed, it is difficult to control the amount of oil used during use. Moreover, when used for the first time, since the bottle is full of oil, the oil cannot be poured out of the bottle body at a large angle, and the oil will leak out along the bottle body, causing inconvenience in use.

[0003] Since the above-mentioned traditional self-sealing bottle cap needs to assemble the rubber plug sheet and the bottom cover, there are still gaps between the parts after the product is manufactured, resulting in poor sealing of the product. In addition, assembly errors will occur during the assembly process of the product, which will eventually lead to loose installation of the rubber plug sheet, uneven product quality, and time-consuming assembly process, which reduces the production efficiency of the product.

[0004] The utility model is produced based on the above-mentioned shortcomings. Utility Model Content

The plug body is provided with an extrusion seam, and the bottle cap also has a safety structure, through which the installation groove where the plug body is located is sealed and covered. When in use, the safety cover is first pulled open by a pull ring, and the bottle is pressed to squeeze the oil out of the extrusion seam of the plug body. This structure is simple, and the size of the safety cover only needs to be consistent with or slightly larger than the installation groove, which can save materials. The plug body has an automatic sealing effect, when the bottle body is squeezed, the oil is squeezed out from the extrusion seam, and when not in use, the extrusion seam is automatically closed, which can effectively protect the oil in the bottle and extend the shelf life of the oil. Moreover, when it is used for the first time or when the oil is full, the plug body can be used to block the bottle, and then the bottle can be squeezed to pour out the oil, so as to avoid leakage when pouring due to too full oil. This can provide better protection for the bottle storage and more convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0024] The present embodiment provides a bottle cap with a self-sealing structure and a safety structure, which is mainly used for oil bottles, and can certainly be used for other bottles for liquids, including a bottom cover 1 and an opening and closing cover 2 that can be covered thereon, the top surface of the bottom cover 1 is provided with a discharge hole 10, the bottom surface of the bottom cover 1 is provided with a mounting groove 11 connected to the discharge hole 10, the mounting groove 11 is provided with a plug body 3 for closing the discharge hole 10, the middle of the plug body 3 is provided with an extrusion seam 30 for extruding the material in the bottle, the top surface of the bottom cover 1 is connected with a safety cover 12 for covering the discharge hole 10, the edges of the safety cover 12 are connected to a circle of easy-to-tear ring parts 13 between the bottom cover 1, and the safety cover 12 is connected with a safety cover for a person to hold by hand to close the discharge hole 10. The cover 12 is torn from the pull ring 14 on the bottom cover 1. When in use, the safety cover 12 is first pulled open through the pull ring 14, and the bottle is pressed to squeeze the oil out of the extrusion slit 30 of the plug body 3. This has a simple structure, and the size of the safety cover 12 only needs to be consistent with or slightly larger than the installation groove 11, which can save materials. The plug body 3 has an automatic sealing function. When the bottle body is squeezed, the oil is squeezed out from the extrusion slit 30. When not in use, the extrusion slit 30 is automatically closed, which can effectively protect the oil in the bottle and extend the shelf life of the oil. Moreover, when used for the first time or when the oil is full, through the obstruction of the plug body 3, the bottle can be tilted at a certain angle first, and then the oil can be poured out by squeezing the bottle to avoid leakage when pouring due to too full oil.

The bottom surface of the bottom cover 1 is provided with an annular outer groove ring 15, and the groove ring forms the mounting groove 11. The bottom surface of the bottom cover 1 is provided with an inner groove ring 16 located on the inner side of the outer groove ring 15, and the outer groove ring 15 and the inner groove ring 16 bracket form an annular plug-in groove 17. When the plug body 3 is connected to the bottom cover 1, the connecting ring 32 of the plug body 3 is inserted into the plug-in groove 17, and the inner groove ring 16 is inserted into the annular groove 33. Since the cover body and the plug body 3 are usually made of different materials, for example, the cover body is made of plastic, and the plug body 3 is made of food-grade silicone or TPE / TPR material, the above structure is used to facilitate the installation of the plug body 3 on the cover body, optimize the structure, simplify the production and installation processes, and improve production efficiency.

[0027] As a preference, Figure 2 and Figure 3 As shown, in order to make the plug body 3 more firmly connected to the cover body, a first snap-fitting protrusion 161 is provided on the outer side wall of the inner groove ring 16, and a second snap-fitting protrusion 321 for snapping onto the first snap-fitting protrusion 161 is provided on the inner side wall of the connecting ring 32.
