Description

A container plug for rapid sealing and opening and an internal push sealing method using the container plug

technical field

The invention relates to the sealing and opening of containers, in particular to a fast sealing and opening container plug and an internal push-type sealing method using the container plug.

Background technique

In the container industry, it is extremely common to manufacture bottles, cans with one or more spouts and/or fill spouts. Such containers are mostly sealed with threaded container plugs or solid plugs, or sealed with other components such as buckles. Taking threaded ones as an example, cumbersome rotation is required during the opening and opening process, especially when the container contains hot drinks or carbonated liquids, the pressure of the container increases, and it takes more time and effort to rotate the container plug. Open. Take the solid plug as an example, because there is no other structure to fix it, the plug design is too small and the sealing effect is poor, so it cannot hold the liquid under pressure. For example, the opening and closing process is complicated and time-consuming, but the parts still need to take up extra space. The existing container plugs have the following problems: quick opening and sealing cannot be achieved, the opening and sealing operations are inconvenient and laborious, the structure is complex and takes up space and wastes resources, and the sealing effect is not good and there is a risk of leakage.

In the shipping container industry, it is extremely common to manufacture bottles, cans, etc. with one or more spouts and/or fill spouts. The opening of this type of container has an internal thread incorporated into the sealing surface of the unthreaded gasket, and an externally threaded sealing plug carrying an annular sealing gasket is threadedly engaged with the opening of the container. When the sealing plug is inserted into the seal, the sealing plug gasket is pressed against the non-threaded gasket sealing surface to achieve effective sealing of the container. When many bottles, jars and other containers are sealed using the above method, on the one hand, there is a critical force in the compression force of the sealing plug and its gasket; , when the necessary force is applied to seal the sealing plug into the opening of the container, the gasket of the sealing plug is wedged into the starting position of the internal thread of the opening for sealing, and when the sealing plug is unscrewed, the gasket of the sealing plug is wedged into the thread of the opening to be tightly pushed Hold the sealing plug gasket, when the sealing plug knob continues, it is easy to cause the sealing gasket to lose force, and even when the sealing plug is separated from the opening, the gasket may still be stuck on the thread of the opening part of the sealing plug, causing the gasket to fall off from the gasket seat of the sealing plug , The gasket and the opening are easy to form a leakage channel, which will damage the gasket and affect the sealing effect. With frequent use, the gasket itself will gradually be damaged due to the applied force, which will gradually weaken the sealing effect of the gasket.

The sealing effect is produced by the engagement of the sealing plug gasket with the sealing plug. When the sealing plug is taken out, the dragging of the sealing plug to the sealing gasket will inevitably occur due to the mutual engagement of the threads. The above problems will inevitably occur sooner or later, which also leads to The durable use of the sealing plug cannot be achieved by thread-tight connection with the gasket.

In order to solve this technical problem, Chinese patent CN104803085A discloses a container plug that can be quickly opened and closed, including a cylindrical plug body, and the cylindrical plug body includes a plug rod, and the bottom of the plug rod is provided with a plug that can be inserted into the container or drawn. The base of the container, the shape and size of the base match the shape and size of the straight section of the container mouth or the shape and size of the smallest section of the container, the upper part of the base is provided with a ring-shaped plug, and the gap between the ring-shaped plug and the base There is an elastic sealing sleeve that can be bent and deformed. Under the action of external force, the annular plug body and the base can make mutual movement along the container axis in the container mouth to squeeze the elastic sealing sleeve, so that the elastic sealing sleeve can expand radially. Bending outwards forms a sealing ring between the container and the base, and the sealing ring together with the base forms a sealing layer for fast closing of the container. It uses a non-threaded bottle stopper, which can be quickly opened and closed for use. However, in this technical solution, the radial dimension of the elastic sealing body is larger than the inner diameter of the container after extrusion, expansion and folding. With such a structure, the contact area between the elastic sealing body and the inner diameter of the container after folding and expansion is small, and the sealing effect is unstable. In addition, in the process of closing the container plug in the prior art, the entire plug body is put into the container first, and then the base is pulled to squeeze the elastic sealing sleeve to achieve the sealing effect. The operation is not simple enough, and the opening and closing operation fingers can only Operating in the direction set by the plug body does not achieve real fast opening and closing.

As a plugging and sealing member for containers, how to solve the problems of sealing stability and fast operation, and how to achieve stable operation and quickly realize the plugging and sealing of the container by the sealing plug is a technical problem to be solved urgently by those skilled in the art.
