Description

Container stopper capable of being sealed and opened quickly

Technical Field

The utility model relates to sealing and opening of a container, in particular to a container plug capable of being rapidly sealed and opened.

Background

In the container industry, it is extremely common to make bottles, cans, with one or more spouts and/or filler openings. Such containers are often sealed with a threaded container stopper or a solid stopper, or by other means such as a snap fit. In the case of a screw thread, the opening and closing process requires a cumbersome rotation, especially when the pressure in the container is increased when the container is filled with hot drinks or carbonated liquids, and it takes more time and effort to rotate the stopper to open the container. Take the solid stopper as an example, because of not fixing with the help of other structures, the stopper design is too little sealed the poor liquid that can not the splendid attire have pressure effect, and the stopper design is difficult when too big opening needs to waste more time with the help of other instruments, takes the example with the help of other parts to seal, and the complicated waste time of opening and closing process action, but the part still needs to occupy extra space. The prior container stopper has the following problems: the quick opening and sealing can not be realized, the opening and sealing operation is inconvenient and labor-consuming, the structure is complex, the occupied space wastes resources, and the sealing effect is poor, so that the leakage risk is caused.

In the shipping container industry, it is very common to manufacture bottles, cans, etc. having one or more spouts and/or injection ports. The opening of such containers has internal threads incorporated into the sealing surface of the threadless gasket and an externally threaded sealing plug carrying an annular sealing gasket is threadably engaged with the opening of the container. When the plug is inserted into the seal, the plug gasket is pressed against the unthreaded gasket sealing surface, resulting in an effective seal against the container. When a plurality of bottles, cans and other containers are sealed in the above manner, on one hand, the pressing force of the sealing plug and the gasket thereof is critical, on the other hand, the threads of the opening of the container are merged into the seat surface of the gasket of the opening gasket, when the sealing plug is sealed and plugged into the opening of the container by applying necessary force, the gasket of the sealing plug is wedged into the starting position of the threads in the opening to be sealed, when the sealing plug is screwed off, the gasket of the sealing plug is wedged into the threads of the opening to tightly support the gasket of the sealing plug, when the knob of the sealing plug continues, the sealing gasket is easy to generate a releasing force, even when the sealing plug is separated from the opening, the gasket can still be sunk into the threads of the opening in the sealing plug, so that the gasket is separated from the gasket seat of the sealing plug, and the gasket and the opening are easy to form a leakage passage, thereby damaging the gasket and affecting the sealing effect. With frequent use, the gasket itself is gradually damaged by the application of force, slowly impairing the sealing action of the gasket.

The sealing effect is generated by the engagement of the sealing plug gasket and the sealing plug, the dragging of the sealing plug to the sealing gasket caused by the mutual engagement of threads is inevitably generated when the sealing plug is taken out, the problems are inevitably generated early or late, and the sealing plug and the gasket cannot be durably used through the threaded sealing connection.

In order to solve the technical problem, chinese patent CN104803085A discloses a container plug capable of being opened and closed quickly, which includes a cylindrical plug body, the cylindrical plug body includes a plug rod, a base is disposed at the bottom of the plug rod and can be inserted into or pulled out of the container, the shape and size of the base are matched with the shape and size of the straight section of the container mouth or the minimum section of the container, an annular plug body is disposed at the upper portion of the base, a flexible sealing sleeve capable of being bent is disposed between the annular plug body and the base, the annular plug body and the base can move mutually in the container mouth along the axial direction of the container under the external force to extrude the flexible sealing sleeve, so that the flexible sealing sleeve expands radially and bends outwards to form a sealing ring between the container and the base, and the sealing ring and the base together form a sealing layer for realizing quick closing of the container. It selects the bottle stopper without screw thread, can open and close the use fast. However, in the technical scheme, the radial size of the elastic sealing body after being extruded and expanded is larger than the inner diameter of the container, the contact area of the elastic sealing body after being folded and expanded in the structure and the inner diameter of the container is small, and the sealing effect is unstable. In addition, in the process of realizing the closure of the container stopper in the prior art, the whole stopper body is firstly placed into the container, and then the base is pulled to extrude the elastic sealing sleeve to realize the sealing effect, the operation action is not simple and convenient enough, the opening and closing operation fingers can only operate in the set direction of the stopper body, and the real quick opening and closing are not realized.

As a sealing member and a sealing member for a container, how to solve the problems of stability of sealing and rapidness of operation, and realizing stable and rapid sealing and sealing of the container by a sealing plug is a technical problem to be solved urgently by those skilled in the art.
