Abstract
A container for medical equipment, said container comprising a base and a lid pivotally connected together. A catch is provided on the lid and the base to hold them together according to a closed position. Upon release of the catch the lid is urged from a closed position to an opened position by at least one spring. Contacting surfaces providing pre-determined frictional resistance are also provided onto the container to control the movement of the lid between the closed and the opened position.
Claims6
A container for medical equipment, said container comprising:
- a base and a lid connected together by pivot means, whereby said lid and said base revolve about said pivot means between a closed position and an opened position;
- catch means provided on corresponding portions of said lid and said base, said catch means cooperating together to hold the lid and the base in the closed position;
- biasing means attached to said base and said lid whereby upon release of the catch means the lid is urged from the closed position towards the opened position by said biasing means;
- controlling means provided on the base and the lid to slow the revolving movement of said lid from the closed position to the opened position by frictional resistance, the frictional resistance provided by contacting surfaces provided on the base and the lid and which are moved relative to each other as said lid is brought from the closed position to the opened position;
- and
- the pivot means comprises at least one shaft extending outwardly from the base and which passes through a corresponding aperture provided in said lid, and wherein a cap is attached at the extremity of the shaft, said cap being sized and shaped with respect to said corresponding aperture so that the lid rotates between the closed position and the opened position;
- and wherein said controlling means comprises said cap and said aperture which are sized and shaped so that they contact each other and that their rotational movements with respect to each other provided a determined frictional resistance.
