Abstract
The present cover has a connector configuration that allows several identical covers to be joined together on top of each other to form a cover system. The covers can be turned with respect to each other so that a label on the cover on the item inside the cover can be easily seen. The connector includes a cylindrical portion which, when mated to an identical cylindrical portion on another cover, permits a pivotable connection. The covers, when joined, can be rotated only in a direction parallel to main surfaces of the covers.

Cover comprising:
- a frame with a first main surface and a second parallel main surface and a surrounding side surface joining the main surfaces at least partially;
- a pivot mechanism extending from the surrounding side surface and intended for joining several identical covers together on top of each other to form a cover system, wherein the covers when joined together can only be moved relative to each other by being turned with respect to each other in a direction parallel to the main surfaces of the covers, and
- a locking mechanism allowing the pivot mechanisms of two covers to be joined when the pivot mechanisms are in a certain position with respect to each other and preventing the covers from separating from each other when the pivot mechanisms are turned in another position with respect to each other, said locking mechanism comprising a semi-circular locking surface extending from said second main surface of the cover and a semi-circular indent on the first main surface of the cover for receiving said semi-circular locking surface of another cover in order to prevent the covers from separating from each other when the covers are joined together at their respective said pivot mechanisms and at least partly turned one on top of the other.
Cover comprising
- a frame with a first and a second mutually parallel main surface and a surrounding side surface joining the main surfaces at least partially;
- a pivot mechanism extending from the surrounding side surface and intended for joining several identical covers together on top of each other to form a cover system, in which the covers can be turned with respect to each other in a direction parallel to the main surfaces of the covers, and
- a locking mechanism allowing the pivot mechanisms of two covers to be joined when the pivot mechanisms are in a certain position with respect to each other and preventing the covers from separating from each other when the pivot mechanisms are turned in another position with respect to each other;
- said pivot mechanism comprising
- a first cylindrical portion with a first diameter;
- a second cylindrical portion positioned coaxially on said first cylindrical portion on the side of said first main surface of the cover and having a second diameter larger than said first diameter, the plane of the second cylindrical portion being parallel to the main surfaces of the cover;
- and
- a semi-cylindrical groove on the side of the second main surface of the cover, dimensioned to receive said second cylindrical portion of another cover;
- said locking mechanism comprising
- a semi-circular locking surface extending from said main surface of the cover;
- and
- a semi-circular indent on the first main surface of the cover for receiving said semi-circular locking surface of another cover in order to prevent the covers from separating from each other when they are joined and at least partly turned one on top of the other.
9 more elements
A cover comprising:
- first and second surfaces parallel to each other and joined together partially at their perimeters by a side wall;
- a connector extending from said side wall and capable of making a pivotable connection with said connector of another said cover, under said pivotable connection said covers being movable with respect to each other only in a direction parallel to said first and second surfaces and said covers being joinable and separable at said connector only when oriented with respect to each other in a predetermined position, said connector comprising a cylindrical portion extending from said side wall and having an outwardly extending flange from one end of said cylindrical portion, and an arcuate groove in said sidewall and adjacent an end of said cylindrical portion opposite said outwardly extending flange, said flange of another said cover being slidably engageable with said arcuate groove as an aspect of said pivotable connection.
