Description

TECHNICAL FIELD

The present disclosure relates to a container cover, and particularly, to a container cover in which an air inflow groove is defined in a sealing member of a typical container cover configured to seal a container regardless of a volume of the container to easily separate the container cover from the container even though a pressure difference between the inside and outside of the container occurs.

BACKGROUND ART

In general, a container for storing foods includes a cover for sealing an inlet of the container. The cover may be manufactured with a size equal to that of the container. Also, a handle may be attached to a side surface of the container or a side surface of the cover.
In recent, a cover of a sealed container which is used for various containers using one cover is disclosed in Korean Utility Model Registration No. 10335581 registered in Korean Intellectual Property Office.
The container cover according to a related art includes a cover body 10 contacting a container on a back surface thereof and a ring-shaped sealing member in which an edge thereof is fixed along an edge of a back surface of the cover body 10 and the remaining portions elastically contact the back surface of the cover body 10.
Since the sealing member 20 is elastically moved, when the sealing member 20 is pulled to descend toward a side surface of the container 30 in a state where the container 30 is placed on a lower end thereof, the container 30 is sealed by strong elasticity of the sealing member 20.

Disclosure

Technical Problem

However, in the container cover according to the related art, when the container containing foods is put into a refrigerator after the container is covered by the container cover, air within the container may be contracted. Thus, it may be difficult to open the container due to a pressure difference even though the whole contact part of the sealing member is lifted up. To solve the above-described limitation, an air inflow groove is defined in the side surface of the cover body of the container cover. However, it may be difficult to seek the air inflow groove and lift the sealing member by a user.

Technical Solution

It is therefore an object of the present disclosure to provide a container cover for covering an upper end of a container includes: a cover body including a flat part on a circumference portion thereof; a coupling part having a ‘
’ sectional shape to surround the cover body; and a sealing member including a contact part in which a plurality of frames are disposed on a lower end of the coupling part, wherein an air inflow groove is defined in the lower end of the coupling part.

Advantageous Effects

According to the present disclosure, since it may be unnecessary to seek the air inflow groove and the user may lift only a portion of the sealing member, it may be easy to use the container. In addition, it may prevent the cover body from being damaged.

MODE FOR INVENTION

A container cover for covering an upper end of a container (30) includes: a cover body (10) including a flat part (12) on a circumference portion thereof; a coupling part (21) having a ‘
’ sectional shape to surround the cover body; and a sealing member (20) including a contact part (22) in which a plurality of frames are disposed on a lower end of the coupling part (21), wherein an air inflow groove (21 a) is defined in the lower end of the coupling part (21).
The cover body 10 may have various shapes according to a shape of the container 30. However, the cover body 10 may mainly have a circular shape.
The cover body 10 may have a flat plate shape. Alternatively, the cover body 10 may have a shape in which a central portion thereof protrudes. However, in the above-described two cases, a flat part 12 is disposed on a circumference portion of the cover body 10.
The sealing member 20 may be formed of a silicon material having elasticity. Also, the sealing member 20 includes a coupling part 21 having a ‘
’ shape and a contact part 22 disposed on a circumference portion of a lower end of the coupling part 21.
An air inflow groove 21 a is defined in the lower end of the coupling part. The air inflow groove 21 a is lengthily defined from a lower end of a sectional surface having the ‘
’ shape of the coupling part 21 up to a portion at which the contact part starts.
A space part B to which an upper end of the container 30 is not completely attached is defined in a coupled portion between the coupling part 21 and the contact part 22 of the sealing member 20 according to the related art. However, according to the present disclosure, the air inflow groove 21 a is defined up to the space part B.
The space part B may be connected along a circumference portion of an upper end of the container 30 when the contact part 22 is closely attached to the outside of the container 30. Thus, when only a portion of the contact part 22 is opened without opening a portion of the contact part in which the air inflow groove 21 a is defined, air may inflow into the container 30.
When the container cover having the above-described structure is covered on the upper end of the container, the contact part 22 of the sealing member 20 is lifted toward the upper end of the cover body 10 and the circumference portion of the upper end of the container 30 is disposed on a lower end of the flat part 12 surrounded by the coupling part 21 of the sealing member 20.
Thereafter, the contact part 22 of the sealing member 20 descends toward the lower end to contact a peripheral portion of the container 30.
In a case where the user puts constants within the container 30 out, when a portion of the contact part 22 is pulled upward, air may flow into the container 30 through the air inflow groove 21 a by the space part B communicating with the air inflow groove 21 a to easily separate the container cover from the container.

Claims

1. A container cover for covering an upper end of a container (30), the container cover comprising:

a cover body (10) comprising a flat part (12) on a circumference portion thereof;

a coupling part (21) having a ‘

’ sectional shape to surround the cover body; and

a sealing member (20) comprising a contact part (22) in which a plurality of frames are disposed on a lower end of the coupling part (21),

wherein an air inflow groove (21 a) is defined in the lower end of the coupling part (21).

2. The container cover of claim 1, wherein the air inflow groove 21 a is lengthily defined from the lower end having the ‘

’ sectional shape of the coupling part (21) up to a portion at which the contact part (22) starts.
