Description

  The present invention relates to a container having an easy-to-seal filling port that is easy to seal after the contents are injected from the filling port on the filling machine so that the filling port cannot be opened or difficult to open. .

Conventionally, after filling the contents into the container, the container is sealed by sealing the filling port with a cap and sealing the portion filled with the contents of the container body by a heat fusion method. There is a method. The latter heat fusion method requires high technology and equipment, and is unsuitable for unfamiliar or small-scale production sites. In the former method using a cap, the cap is attached to the filling port of the container by a screwing method or a plugging method. However, these methods are based on the premise that the consumer opens the cap at the time of use. As a method for preventing the consumer from opening the filling port, in the case of the screwing method, for example, a ratchet is formed on the outer peripheral surface below the filling port of the container and the inner peripheral surface below the cap, respectively. When these ratchets turn the cap in the loading direction, the cap ratchet gets over the container filling port ratchet, and when the cap turns in the screwing direction, the cap ratchet turns the container filling port ratchet. (See Patent Document 1).

  However, when the height of the ratchet is increased to secure the engagement between the ratchet of the cap and the ratchet of the container filling port when the cap is turned in the screwing direction, when the cap is attached to the container filling port. In addition, a large closing torque was required. If the cap is forcibly screwed onto the filling port of the container, the cap or the filling port of the container may be distorted to cause liquid leakage or impair the filling machine.

  The present invention solves the above-described problems in sealing the filling port of the conventional container, and easy-sealing that can be easily sealed on the filling machine so that the filling port cannot be opened or is difficult to open. A container having a filling port is provided.

  In other words, the first invention of the present invention is a container that is installed by screwing a sealing cap into the filling port of the container, and the sealing cap comprises an upper part, an intermediate part, and a lower part. Steps are provided at the lower end and the lower end of the intermediate part, the outer diameter of the upper part is larger than the outer diameter of the intermediate part, and the outer diameter of the intermediate part is larger than the outer diameter of the lower part. Fill the container with a male screw with a filling port, a vertical knurling thread on the inner peripheral surface, a sealing plate on the inner lower side and a hook ring with the filling port on the lower outer peripheral surface on the lower part The mouth consists of an upper part and a lower part, a step is provided at the lower end of the upper part, the outer diameter of the upper part is larger than the outer diameter of the lower part, and the upper part has a sealing cap on the inner peripheral surface The lower part of the inner peripheral surface of the lower inner side is provided with a stepped portion at the lower end of the middle part of the sealing cap. A contact ring whose surface is in contact with the upper surface is provided, and a plurality of hook plates are provided on the inner peripheral surface of the contact ring at equal intervals in the circumferential direction via hinges, and the sealing cap is placed in the filling port of the container. The hooking plate is bent downward at the tip of the lower part of the sealing cap when screwed to the hook, and the hooking ring of the lower part of the sealing cap is hooked on the tip of the hooking plate of the contact ring of the filling port of the container. A container with an easy-to-seal filling port.

  And the 2nd invention of the present invention is that the thickness of the sealing plate provided inside the lower part of the lower part of the sealing cap is set at the tip of the nozzle when the nozzle of the automatic suction type dispensing device is inserted inside the sealing cap.
