Abstract

The invention discloses a double-opening sealing cover which comprises an upper cover body and a bottom cover body. The bottom cover body is provided with an upper opening and a lower opening capableof communicating with the upper opening, and the upper cover body is rotationally connected to the upper opening of the bottom cover body. The lower opening of the bottom cover body is connected to acontainer opening, and an air inlet and a liquid outlet are formed in the upper cover body. Accordingly, a communicating liquid outlet structure is arranged in the bottom cover body. When the upper cover body rotates, the communicating liquid outlet structure can make the air inlet and the liquid outlet to communicate with the upper opening of the bottom cover body at the same time. In an initialstate, the upper opening of the bottom cover body is airtight and isolated from the air inlet and the liquid outlet. According to the double-opening sealing cover, the air inlet and the liquid outletare formed in the upper cover body, the air inlet and the liquid outlet are controlled to communicate with the upper opening of the bottom cover body or be airtight and isolated from the upper openingof the bottom cover body through the communicating liquid outlet structure and rotation of the upper cover body relative to the bottom cover body, and the beneficial effects of being clean and tidy and sanitary are achieved. Liquid in a packaging bottle can be prevented from being contaminated, meanwhile, the air inlet is formed in the upper cover body, liquid pouring is smoother, and bubbles arenot likely to be generated. In addition, the beneficial effects of being simple in structure and convenient and fast to operate are achieved.

Description

【Technical field】 [0001] The invention relates to a bottle cap of a container, in particular to a double-mouth closing cap. 【Background technique】 [0002] The bottle caps of soy sauce bottles, cooking oil and other containers that are common in the market usually include a bottom cap and an upper cap connected to the bottle mouth. The upper cap acts as a seal, and the cap has only one opening, which is used as an air inlet and liquid outlet at the same time. The mouth is not smooth and easy to produce air bubbles when pouring. [0003] The upper cover and the bottom cover are mostly connected in the following two ways: [0004] 1. The upper cover is directly connected to the bottom cover through threads, and the upper cover is directly unscrewed when in use; [0005] 2. The upper cover is fastened on the bottom cover, and there is a flexible connector between the upper cover and the bottom cover. When in use, the upper cover is directly separated from the bottom cover; ...
