Title: Spring hinged cap
Inventor: KOBAYASHI YASUTOMO
IPC: B65D43/24
Filed: 2001-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a spring hinged cap which is good in appearance, whose manufacturing cost can be reduced and which does not apply a load to a hinge. SOLUTION: An engaging portion 30 is located on a moving track of an elastic member 34, and a groove 36 is formed at the center of the elastic member 34 to align with a width of the engaging portion 30. Thus, as soon as a lid 14 is closed, the engaging portion 30 and the groove 36 are engaged with each other. In addition, in a process that the lid 14 is closed, a tip of the elastic member 34 presses the engaging portion 30 to elastically deform, and further when an open/close angle of the lid 14 reaches approximately 90 degrees, the tip passes by the engaging portion 30 to cause the groove 36 to engage with the engaging portion 30. Thus the engaging portion 30 traces the groove 36 when the lid 14 is opened/closed, decreasing a rattle when opening/closing.  Since the engaging portion 30 elastically deforms, an amount of the elastic member 34 deforming when the portion 30 is engaged with the groove 36 is small, thereby preventing an excessive load from being applied to the member 34.
