container with lid

Abstract

The present invention provides a container with a lid equipped with a free-stop mechanism that can prevent malfunctions caused by frequent opening and closing operations or changes over time. [Solution] A container 1 comprising a container body 2 having an opening 21 for storing contents, and a lid 3 connected to the container body via a hinge to cover the opening so as to be able to open and close, wherein the hinge's axis of rotation 100 is in the left-right direction, and the hinge is composed of a pin 5 provided so as to be immovable from either the container body or the lid and protruding coaxially with the axis of rotation, a recess 35 provided coaxially with the axis of rotation on the other of the container body or the lid, and a tubular bush 6 inserted coaxially into the recess so as to be immovable, wherein the pin is inserted into the bush in a tightly fitted state, and the lid rotates around the axis of rotation so as to be fixed in the open state, and the bush has regions sandwiched at both the left and right ends that are separated from the inner surface of the recess with a gap.

Claims

1. A container comprising a container body having an opening for storing contents, and a lid connected to the container body via a hinge and capable of opening and closing to cover the opening, The axis of rotation of the aforementioned hinge is set in the left-right direction. The hinge comprises a pin provided so as to be immovable from either the container body or the lid and protruding coaxially with the rotation axis, a recess provided coaxially with the rotation axis in the other of the container body or the lid, and a tubular bush inserted coaxially into the recess so as to be immovable. The pin is inserted into the bush in a tightly fitted state, and the cover rotates around the rotation axis so that it can be fixed in the open state. The bush is separated from the recess by having a gap in the region sandwiched between the left and right ends. A container with a lid.

2. The container with a lid according to claim 1, wherein the bush has projections that protrude radially outward from both the left and right ends and contact the inner surface of the recess.

3. The container with a lid according to claim 2, wherein the projections are formed intermittently at multiple locations around the rotation axis, and the inner surface of the recess is shaped to engage with the projections to prevent the bush from rotating.

4. With reference to the state in which the lid is closed, the rotation axis is located on one end in the front-to-back direction, which is perpendicular to the left-to-right direction. The hinge has a notch formed on one end of either the container body or the lid, a through hole formed coaxially with the rotation axis and communicating with the notch, and a protrusion formed on the other end of either the container body or the lid to engage with the notch. The recess is formed in the protrusion, The pin is inserted through the through hole, with its tip protruding into the notch and press-fitted into the bush in the recess. A container with a lid according to claim 1.

5. A lidded container according to any one of claims 1 to 4, wherein the container body, the lid, the pin, and the bush are made of resin.
