Abstract

The invention discloses a self-sealing type bottle cap for an oil bottle. The seal-sealing type bottle cap for the oil bottle consists of a sealing cap, a one-way valve and a bottle cap body, wherein the sealing cap consists of a cap opening and a cap body; the cap body is in threaded connection with the bottle opening of the oil bottle; a sealing surface is arranged on the inner side of the cap opening; the one-way valve is arranged on the sealing cap and consists of a valve seat, a valve rod, a spring blocking cushion and a spring; one end of the valve rod is integrally connected with the valve seat; the other end of the valve rod is provided with the spring blocking cushion; the spring is arranged on the valve rod and is positioned by the spring blocking cushion; the valve seat is positioned at the cap opening of the sealing cap and is in plane contact with the sealing surface of the cap opening; and the bottle cap body is in threaded connection to the cap opening of the sealing cap. The self-sealing type bottle cap for the oil bottle has the advantages that oil in the oil bottle can flow out through the one-way valve, but air cannot enter the oil bottle from the bottle opening, so that edible oil in the bottle is isolated from the air, oxidation of the edible oil is stopped, the expiration date of the edible oil is prolonged, and the edible oil is safe to eat.

Description

technical field [0001] The invention relates to a bottle cap, in particular to a bottle cap with a self-sealing structure. The bottle cap of the invention is suitable for edible oil packaging bottles. Background technique [0002] Fat is one of the important nutrients and energy sources in people's diet. The quality of fats and oils and the rationality of eating methods have a great impact on human health. Therefore, the safety of edible fats and oils is more and more concerned by people. [0003] During the storage and consumption of edible oils and fats, the unsaturated fatty acids in them are easily oxidized by light, heat, enzymes, metal ions, etc., resulting in rancidity and deterioration of the oils, and at the same time produce a pungent smell (commonly known as hala smell). Every year, there are many cases of acute food poisoning caused by eating rancid oily food in our country. [0004] In order to prevent or delay the deterioration of edible oils and fats, measu...
