Description

Sealing cap with two-way snap mechanism

The present invention relates to a cover body technology of a sealed can, in particular to a sealed cover with a two-way buckle mechanism.

Press, the airtight jar generally includes a container and a cover body with an airtight cover at the opening of the container. The cover body is detachably covered on the container. In order to airtightly close the opening of the container, the bottom edge of the cover body will An annular gasket is embedded, so that the gasket is airtightly stacked on the periphery of the opening of the container to achieve the sealing effect.

Since the existing sealing cover must be dismantled and washed frequently, the industry has developed a sealing cover with both a handle and an elastic element. The sealing cover performs a pressing operation on the handle and squeezes and deforms the gasket through the elastic force of the elastic element. to achieve a sealing effect. However, in the process of assembly and disassembly of this type of sealing cover, some parts need to be dismantled and disassembled for most of the components, and some only have a single-direction insertion port for assembly, which makes the assembly and disassembly during disassembly and cleaning extremely difficult. convenient.

In view of this, the inventor of the present invention has devoted himself to the study of the above-mentioned prior art and cooperated with the application of theories, trying his best to solve the above-mentioned problems, which is the goal of the present inventor's improvement.

One objective of the present invention is to provide a sealing cover with a two-way locking mechanism, which is fastened with a two-way inserting opening on the fastener, so as to improve the convenience of assembly and disassembly.

In order to achieve the above-mentioned object, the present invention provides a sealing cover with a two-way locking mechanism, comprising an upper cover member, a lower cover member, a fastener, an elastic element and a handle member, the upper cover member includes a top plate, in the The top plate is provided with a through hole; the lower cover member is arranged below the upper cover member, and the lower cover member includes a bottom plate; the fastener is connected to the bottom plate and penetrates the through hole to expose the outside of the top plate, the fastener There are two interlocking grooves corresponding to each other, each of the interlocking grooves includes a sliding channel, a first inserting opening and a second inserting opening, the first inserting opening and the second inserting opening are respectively formed At both ends of the sliding channel; the elastic element is elastically clamped between the top plate and the bottom plate; the handle member includes a toggle handle and two arms extending from the toggle handle, each of the arms extending There is a shaft, and each of the shafts can selectively enter from one of each of the first insertion openings and each of the second insertion openings, so as to be able to move in each of the sliding passages.

The present invention also has the following effects: by arranging the fastening hole and the climbing slope in the sliding channel, each shaft can be clamped into the fastening hole to achieve a stable positioning effect at the same time. Due to the integral molding of the bottom plate and the sealing ring, during the disassembly and cleaning process, there will be no problems such as missing parts, wrong assembly or omission and non-installation. Through the setting of the sliding channel, the handle member is more smoothly and easily operated when turning and positioning. Not only the overall structure is simplified, the action is stable, but also the sealing effect is good.
