Abstract
According to one embodiment, an airtight container includes a container body having an opening and an airtight cover separably coupled to the opening of the container body, wherein the airtight cover includes a cover body for covering the opening, a hinge base extended outward from the cover body, a flap connected to be rotatable, relative to the hinge base, by means of a bent part provided at one side thereof and a support protrusion which is extended in the direction oriented toward the cover body from one side of the flap.
Claims13
An airtight container comprising a container body and an airtight cover, the container having an opening, the airtight cover configured to be separably coupled to the opening of the container body,
- wherein the airtight cover comprises:
- a cover body configured to cover the opening;
- a hinge base extending outward from the cover body;
- a flap rotatably connected to the hinge base by a fold part formed on one side thereof;
- and
- a support protrusion extending from the one side of the flap in a direction heading towards the cover body, the support protrusion having a contact part formed on an end portion thereof, the contact part configured to contact the container body,
- wherein rotating the flap downward with respect to the hinge base causes a contact support surface of the contact part to press against the container body and allows the airtight cover to be coupled to the container body,
- and wherein, for a reference line defined as an imaginary line running from a center of the cover body along a horizontal direction towards a center of the contact support surface and for a pressure point defined as a point at which the container body applies a normal force in an outward direction onto the contact support surface, the fold part is located under the pressure point and is located further outward compared to the pressure point along the reference line when the airtight cover is in a coupled state with respect to the container body.
An airtight cover separably coupled to an opening of a container body, the airtight cover comprising:
- a cover body configured to cover the opening;
- a hinge base extending outward from the cover body;
- a flap rotatably connected to the hinge base by a fold part formed on one side thereof;
- and
- a support protrusion extending from the one side of the flap in a direction heading towards the cover body, the support protrusion having a contact part formed on an end portion thereof, the contact part configured to contact the container body,
- wherein rotating the flap downward with respect to the hinge base causes a contact support surface of the contact part to press against the container body and allows the airtight cover to be coupled to the container body,
- and wherein, for a reference line defined as an imaginary line running from a center of the cover body along a horizontal direction towards a center of the contact support surface and for a pressure point defined as a point at which the container body applies a normal force in an outward direction onto the contact support surface, the fold part is located under the pressure point and is located further outward compared to the pressure point along the reference line when the airtight cover is in a coupled state with respect to the container body.
