Openable and closable container

Abstract

An openable and closeable container that includes a container body having a take-out opening; an opening-closing lid provided on the container body swingably about a swing axis X-X on a base end side, the opening-closing lid opening/closing the take-out opening; and plate rubber (an elastic member) provided between the container body and the opening-closing lid. A spring body is provided on the base end side of the opening-closing lid and a sloping portion (a braking portion) with which the spring body comes into contact is provided on the container body side. The spring body is gradually compressed from the state where the opening-closing lid is closed toward the state where the opening-closing lid is opened.

1 . An openable and closeable container comprising:
 a main body having a take-out opening;   an opening-closing lid provided on the main body swingably about a swing axis on a base end side of the lid, the opening-closing lid opening and closing the take-out opening; and   an elastic member provided between the main body and the opening-closing lid;   wherein a spring body is provided on the base end side of the opening-closing lid and a braking portion with which the spring body comes into contact is provided on a main body side; and   wherein, as the opening-closing lid opens, the opening-closing lid pivots toward a fully opened position to bring the spring body into contact with the braking portion, thereby allowing the opening-closing lid to stand still at the fully opened position.   
     
     
         2 . The openable and closeable container according to  claim 1 ,
 wherein the opening-closing lid is formed with an opening portion on the base end side and the spring body is composed of an outer circumferential portion of the opening portion.   
     
     
         3 . The openable and closeable container according to  claim 2 ,
 wherein the spring body is composed of an arcuate member bending outward from a base end edge portion of the opening-closing lid.   
     
     
         4 . The openable and closeable container according to  claim 2 ,
 wherein the spring body is composed of a generally turned square U-shaped member projecting outward from a base end edge portion of the opening-closing lid.   
     
     
         5 . The openable and closeable container according to  claim 2 ,
 wherein the spring body is composed of a linear member extending horizontally along a base end edge portion of the opening-closing lid.   
     
     
         6 . The openable and closeable container according to  claim 4 ,
 wherein the spring body is partially cut away to form a cut-away portion, the cut-away portion communicating with the opening portion.   
     
     
         7 . The openable and closeable container according to  claim 3 ,
 wherein a cover is provided at part of the base end edge portion of the opening-closing lid for covering a space between the opening-closing lid and the main body, wherein the spring body is not formed at the part of the base end edge portion.   
     
     
         8 . The openable and closeable container according to  claim 2 ,
 wherein the braking portion is composed of a rib having an arcuate inner surface bending inward, as viewed from the side.   
     
     
         9 . The openable and closeable container according to  claim 1 ,
 wherein the spring body is composed of a C-shaped member provided to encompass the swing axis in a lateral portion of the opening-closing lid, the C-shaped member being partially cut away on an opening-closing lid side;   wherein the braking portion is composed of a tubular body encompassing an outer circumference of the spring body; and   wherein, as the opening-closing lid opens, the opening-closing lid pivots toward the fully opened position to bring the spring body into contact with the braking portion, thereby allowing the opening-closing lid to stand still at the fully opened position.   
     
     
         10 . The openable and closeable container according to  claim 9 ,
 wherein the spring body composed of the C-shaped member is provided, on an outer circumference of the spring body, with a plurality of projections in contact with an inner surface of the tubular body.   
     
     
         11 . The openable and closeable container according to  claim 1 ,
 wherein a pair of longitudinally extending slits is formed on the base end side of the opening-closing lid and the spring body is composed of a tongue piece formed between the pair of slits.   
     
     
         12 . The openable and closeable container according to  claim 11 ,
 wherein the spring body composed of the tongue piece is formed at each of both ends, on the base end side, of the opening-closing lid.   
     
     
         13 . An openable and closeable container comprising:
 a main body having a take-out opening;   an opening-closing lid provided on the main body swingably about a swing axis on a base end side, the opening-closing lid opening and closing the take-out opening; and   an elastic member provided between the main body and the opening-closing lid,   wherein a spring body is provided on the base end side of the opening-closing lid and a stopper portion for stopping opening of the opening-closing lid is provided on a main body side; and   wherein, as the opening-closing lid opens, the opening-closing lid pivots toward a fully opened position to bring the spring body into elastic contact with the stopper portion, thereby allowing the opening-closing lid to stand still at the fully opened position.   
     
     
         14 . The openable and closeable container according to  claim 13 ,
 wherein the opening-closing lid has an L-shaped slit formed on the base end side of the opening-closing lid and the spring body is composed of a lateral piece extending in a lateral direction along the L-shaped slit.
