Easy-to-clean sealing unit

Abstract

An easy-to-clean sealing unit is provided for sealing a container, comprising a base and an airtight gasket. The base is detachably attached to the container and includes a mounting groove and at least one through-hole communicating with the outside of the mounting groove. The at least one through-hole has a first opening facing the mounting groove and a second opening facing the outside. The airtight gasket is fitted into the mounting groove and completely blocks the first opening of the at least one through-hole. The airtight gasket can be pushed out of the mounting groove by a pusher inserted through the second opening. With this design, a user can easily detach the airtight gasket from the mounting groove by inserting the pusher into the second opening and pushing the airtight gasket, thus achieving easy cleaning of the airtight gasket and the base.

Claims

1. An easy-to-clean sealing unit suitable for sealing an opening of a container and used with a pusher, the easy-to-clean sealing unit comprising: a base detachably attached to the container and including a mounting groove and at least one through hole communicating with the outside and the mounting groove, the at least one through hole having a first opening facing the mounting groove and a second opening facing the outside, the second opening into which the pusher can extend; and an airtight gasket fitted into the mounting groove and completely blocking the first opening of the at least one through hole, wherein when the base is attached to the container, the airtight gasket is airtightly pressed against the container and the base, and when the base is not attached to the container, the airtight gasket can be pushed away from the mounting groove by the pusher extending through the second opening.

2. The easy-to-clean sealing unit as described in claim 1, wherein, The base includes several spaced-apart through holes.

3. The easy-to-clean sealing unit as described in claim 1, wherein, The at least one through hole is circular, elliptical, or polygonal.

4. The easy-to-clean sealing unit as described in claim 1, wherein, The base can be made of plastic, glass, ceramic, or metal.

5. The easy-to-clean sealing unit as described in claim 1, wherein, The base includes a base wall portion, and a first annular wall portion and a second annular wall portion extending from the base wall portion toward the container and spaced apart from each other, the base wall portion, the first annular wall portion and the second annular wall portion cooperating to define the mounting groove.

6. The easy-to-clean sealing unit as described in claim 5, wherein, The base wall has at least one through hole.

7. The easy-to-clean sealing unit as claimed in claim 5, the container comprising a bottom wall and a surrounding wall extending upward from the bottom wall and defining the opening, the surrounding wall having a first engagement structure, wherein, The first ring wall portion has a second connecting structure for connecting with the first connecting structure, thereby enabling the base and the airtight gasket to be sealed and positioned on the container.

8. The easy-to-clean sealing unit as claimed in claim 5, the container comprising a bottom wall, and a surrounding wall extending upward from the bottom wall and defining the opening, the surrounding wall having an inner side and an outer side with opposite sides, and a first engagement structure disposed on the outer side, wherein, The base also includes several ears that extend outward from the base wall and are spaced apart. Each ear can swing up and down relative to the base wall and has a second coupling structure. Each second coupling structure can be coupled with the first coupling structure, so that the base and the airtight gasket can be used to seal and position the container.
