Abstract

A container and cap assembly has a container and a cap. The cap covers the container, and has an inner cover, a piston, a slider, and an outer cover. The piston is disposed in the inner cover, and is axially movable therein. The slider is mounted on the piston, and is radially movable to move the piston. The outer cover receives the inner cover, the piston, and the slider. The outer cover is rotated in a first direction to close the container, and is continuously rotated in the first direction to move the slider radially and reciprocatingly so as to move the piston axially and reciprocatingly. The piston is moved to exhaust air from the container to produce a vacuum or approximate vacuum in the container. Therefore, contents in the container are protected from moisture without a desiccant material.

Description

Covered container combination and its lid

The invention relates to a covered container combination, in particular to a covered container combination that can be reused and effectively prevents the articles in the container from being wet.

Covered container combinations are generally used to store items, such as medicines or cosmetics, to prevent items from getting dirty or accumulating dust. A conventional conventional container combination includes a container and a lid. The aforementioned container includes a neck having an external texture. The cover includes a cylindrical side wall. The aforementioned side wall has an inner pattern corresponding to an outer pattern of the neck of the container. A desiccant can be placed inside the aforementioned container to absorb moisture to prevent the contents of the container from getting wet. However, general desiccants cannot be recycled. When moisture is completely absorbed, the desiccant becomes ineffective. The user needs to periodically change the desiccant in the container to keep the container dry.

Therefore, there is a need for a container that is more effective in protecting items from moisture.

In view of this, an object of the present invention is to provide a covered container assembly. In the covered container assembly of the present invention, a piston assembly is added to the container, and air is evacuated from the container by rotating the lid to generate a vacuum or a state close to the vacuum in the container. In this way, the contents of the container can be protected from moisture, and the use of dry air is not required.

To achieve the above object, the present invention provides a covered container combination including a container and a lid. The lid covers the container, and has an inner lid, a piston, a slider, and an outer lid. The piston is disposed in the inner cover and moves axially in the inner cover. The slider is disposed on the piston and moves the piston in a radially movable manner. The outer cover houses the inner cover, the piston, and the slider. The outer cover is rotated in a first direction to cover the container, and is continuously rotated in the first direction to reciprocate the slider in a radial direction and reciprocate the piston in an axial direction. The piston moves back and forth in the axial direction to evacuate air from the container to generate a vacuum or near a vacuum in the container.

To achieve the above object, the present invention also provides a cover including an inner cover, a piston, a slider, and an outer cover. The piston is provided on the inner cover in an axially movable manner. The slider is disposed on the piston and moves the piston in a radially movable manner. The outer cover houses the inner cover, the piston, and the slider. When the outer cover is rotated in a first direction, the slider is reciprocated in a radial direction so that the piston is reciprocated in an axial direction.

To achieve the above object, the present invention further provides a piston assembly including an inner cover, a piston, and a slider. The piston is disposed in the inner cover and moves axially in the inner cover. The slider is disposed on the piston and moves the piston in a radially movable manner.

To sum up, the covered container assembly provided by the present invention includes a piston assembly in the container, and the air is evacuated from the container by rotating the lid to generate a vacuum or a state close to the vacuum in the container. In this way, the contents of the container can be protected from moisture, and the use of dry air is not required.

The outer cavity 285 refers to a space between the side wall 281, the upper wall 282, and the flange 283. The outer cavity 285 houses the inner cover 21, the piston 22, the first valve 23, the second valve 23 a, the slider 24, and the seal ring 27. In this way, the aforementioned ratchet teeth 284 can selectively restrict the movement of the claw portion 245 of the aforementioned slider 24. The indicating portion 25 is disposed in the center hole 2821 of the upper wall 282.

The outer cover 28 is pressed down and rotated in a first direction to tighten the lid 20 on the neck 11 of the container 10. Then, when the outer cover 28 is stopped from being depressed and the outer cover 28 is continuously rotated in the first direction, the ratchet teeth 284 push the claw portion 245 of the slider 24 to reciprocate the slider 24 in the radial direction. The piston 22 moves back and forth in the axial direction. When the outer cover 28 rotates in the second direction, the ratchet teeth 284 restrain the claw portion 245 of the slider 24, so the lid 20 can be turned away from the neck 11 of the container 10. At this time, the slide The block 24 stops moving in the radial direction, and the aforementioned piston 22 stops moving in the axial direction. In a preferred embodiment, the outer cover 28 rotates to cover the container 10 in a clockwise direction, and continues to rotate in a clockwise direction to cause the ratchet teeth 284 to push the claw portion 245 of the slider 24, as shown in FIG. 7 As shown in Figure 8. The outer cover 28 is rotated in a counterclockwise direction to open the container 10, and the ratchet teeth 284 restrict the movement of the claw portion 245 of the slider 24, as shown in FIG. 9. The outer cover 28 has five ratchet teeth 284. Therefore, rotating the outer cover 28 clockwise 360 degrees allows the slider 24 to reciprocate radially five times, and the piston 22 to reciprocate axially five times.

The aforementioned outer cover 28 is rotated clockwise to cover the aforementioned container 10. Referring to FIGS. 7 and 8, the outer cover 28 is continuously rotated clockwise to cause the ratchet teeth 284 to push the claw portion 245 of the slider 24, so the slider 24 moves back and forth in the radial direction, and the piston 22 faces Reciprocating axially. The movement of the piston 22 causes the air in the container 10 to be exhausted, so that the container 10 generates a vacuum or a state close to the vacuum. The process in which the container 10 generates a vacuum or a state close to a vacuum is shown in FIG. 10. The arrows in FIG. 5 and FIG. 6 represent the airflow flowing from the aforementioned container 10. Therefore, articles (such as medicines or cosmetics) placed in the aforementioned container 10 can be protected from moisture, and the desiccant is not required. The outer cover 28 is rotated counterclockwise to open the container 10 to allow air to flow into the container 10 and release the vacuum state in the container 10.

The inner cover 21, the piston 22, the first valve 23, the second valve 23a, and the slider 24 constitute a piston assembly. The aforementioned piston combinations can be used to transfer gas (such as air) or liquid (such as water or oil).

The above description is exemplary only, and not restrictive. Any equivalent modification or change made without departing from the spirit and scope of the present invention shall be included in the scope of the attached patent application.
