Description

Technical Field

[0001] The utility model belongs to the technical field of oil bottles, and particularly relates to an oil bottle with a flip-top for refueling. Background Technique

[0002] To cook delicious dishes, edible oil is usually used. Most of the edible oil people buy is in barreled form. Barreled edible oil is large in volume and heavy in weight. If the barreled edible oil is directly used for pouring when cooking, the operation is very inconvenient. Therefore, people usually first pour a part of the edible oil into an oil bottle and then pour out the edible oil through the oil bottle.

[0003] An oil bottle generally has a bottle body and a bottle cap threadedly connected to the upper part of the bottle body, and an oil outlet structure is provided on the bottle cap. When it is necessary to replenish the edible oil in the bottle body, the bottle cap needs to be rotated and removed. After replenishing the edible oil, the bottle cap is tightened by threading again. This structure is relatively troublesome to operate. And after the bottle cap is removed and placed on a tabletop or a container, the oil drops carried on the bottle cap may drip onto the tabletop or the container, and the dripping oil drops need to be cleaned up later; at the same time, if the tabletop or the container itself is not clean, it will cause pollution to the bottle cap.

[0004] To solve the above problems, an oil bottle with a flip-top for refueling appears. In the patent CN202321877030.1, an automatic opening and closing oil pot is disclosed, which includes a pot body and a cover body provided on the pot body. The cover body includes a fixed base threadedly connected to the pot body and an oil pot head rotatably connected to the fixed base. When the oil pot is tilted, the flip-top rotates along the rotating shaft under the action of the gravity of the counterweight block, and at this time the oil outlet pipe is exposed. When the oil pot is placed flat, the flip-top rotates back to its original position along the rotating shaft under the action of the gravity of the counterweight block; a pressing switch assembly is provided on the fixed base, a second fastening portion capable of being fastened and connected to the first fastening portion is provided on the oil pot head, a pin seat is further provided on the fixed base, the oil pot head is rotatably connected to the fixed base through a pin shaft inserted into the pin seat, and a torsion spring is provided in the pin seat. One end of the torsion spring is fixedly inserted into the pin seat, and the other end of the torsion spring abuts against the oil pot head.

[0005] In the above patent, a convex pin seat is provided on the fixed base, two hinge ears are provided on the oil pot head, a first pin hole is opened on the pin seat, and a second pin hole is opened on the hinge ear. The oil pot head and the fixed base are hinged by inserting the pin shaft into the first pin hole and the second pin hole. In order to prevent the pin shaft from falling off, a limiting structure needs to be provided between the pin shaft and the pin seat or between the pin shaft and the hinge ear. And the protrusion of the pin seat and the hinge ear, on the one hand, causes the oil bottle to occupy a large space, increasing the transportation and storage costs; on the other hand, when the oil pot head rotates and opens, a large rotating space is required; thirdly, it affects the appearance quality of the oil bottle and is not conducive to the market competitiveness of the oil bottle.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention
