Abstract
Abstract A sterilization case comprises a top wall member having a pair of depending side walls, a bottom wall member having a pair of upstanding front and rear walls, upstanding post members disposed at each side edge of the front and rear walls and attached to the front and rear walls and a handle member pivotally attached to each side wall with its axis of rotation and its longitudinal axis parallel to the longitudinal axis of its associated side wall and with a portion of it pivotally disposable between adjacent associated posts affixed to the front and rear walls. Each post comprises a neck extending above the upper edge of the front and rear walls and a head surmounting the neck whose minimum transverse dimension is greater than the maximum transverse dimension of the neck, and the top wall has a pair of recesses extending rearwardly from its front edge and a pair of apertures disposed adjacent its rear edge. Each recess and aperture is provided with a concave extension at its rear edge configured to underly the head and restrain upward movement of the top wall. The longitudinal dimension of the handle is approximately equal to the distance between associated posts affixed to the front and walls so that the handle can prevent rearward sliding movement of the top wall and its associated side walls.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
333 words
A case comprising a top wall member being provided with a pair of attached, parallely opposed, depending side walls, a bottom wall member being provided with a pair of attached, parallely opposed, upstanding front and rear walls, at least four upstanding post members with a post member disposed at each side edge of the front and rear walls and attached to the front and rear walls, each post comprising a neck extending above the upper edge of the front and rear walls and a head surmounting said neck whose minimum transverse dimension is greater than the maximum transverse dimension of said neck, and a handle member pivotally attached to each side wall with its axis of pivoting rotation and its longitudinal central axis disposed in parallel relation to the longitudinal central axis of its associated side wall and with a portion of it pivotally disposable between an adjacent post affixed to the front wall and an adjacent post affixed to the rear wall, said top wall being provided with a pair of recesses extending rearwardly from the front edge of said top wall, each recess being open to the front edge of said top wall and being provided with a concave extension at its rear edge configured to underly said head and restrain upward movement of said top wall and a pair of apertures disposed adjacent the rear edge of said top wall, each aperture being generally rectangular in top plan view and being provided with a concave extension at its rear edge configured to underly said head and restrain upward movement of said top wall, the longitudinal dimension of said handle being approximately equal to the distance between an adjacent post affixed to the front wall and an adjacent post affixed to the rear wall so that said handle, when disposed between an adjacent post affixed to the front wall and an adjacent post affixed to the rear wall, prevents rearward sliding movement of said top wall and its associated side walls.
Claim 2
Dependent Claim

A case comprising a top wall member being provided with a pair of attached, parallely opposed, depending side walls, a bottom wall member being provided with a pair of attached, parallely opposed, upstanding front and rear walls, at least four upstanding post members with a post member disposed at each side edge of the front and rear walls and attached to the front and rear walls, each post comprising a neck extending above the upper edge of the front and rear walls and a head surmounting said neck whose minimum transverse dimension is greater than the maximum transverse dimension of said neck, and a handle member pivotally attached to each side wall with its axis of pivoting rotation and its longitudinal central axis disposed in parallel relation to the longitudinal central axis of its associated side wall and with a portion of it pivotally disposable between an adjacent post affixed to the front wall and an adjacent post affixed to the rear wall, said top wall being provided with a pair of recesses extending rearwardly from the front edge of said top wall, each recess being open to the front edge of said top wall and being provided with a concave extension at its rear edge configured to underly said head and restrain upward movement of said top wall and a pair of apertures disposed adjacent the rear edge of said top wall, each aperture being generally rectangular in top plan view and being provided with a concave extension at its rear edge configured to underly said head and restrain upward movement of said top wall, the longitudinal dimension of said handle being approximately equal to the distance between an adjacent post affixed to the front wall and an adjacent post affixed to the rear wall so that said handle, when disposed between an adjacent post affixed to the front wall and an adjacent post affixed to the rear wall, prevents rearward sliding movement of said top wall and its associated side walls.
Claim 3
Dependent Claim
155 words
A case in accordance with claim 1, wherein the distance from the rear edge of the extension of said recess to the front edge of said top wall is less than the distance from the rear edge of the extension of said aperture to the front edge of said aperture and the distance between side edges of adjacent recesses is approximately equal to the distance between confronting points on the necks of adjacent posts on the front wall and the distance between side edges of adjacent apertures is at least approximately equal to the distance between confronting side edges of the heads of adjacent posts on the rear wall so that, when the posts on said rear wall are aligned with their associated apertures and in position for the top wall to move upwardly, a portion of the front edge of said top wall may make pivotal contact with the post on said front wall.
Claim 4
Dependent Claim
60 words
A case in accordance with claim 1, wherein each post is provided with a centrally disposed foot depending from its body and each head is provided with a centrally disposed recess, said recess and the lower extremity of said foot being complementarily configured to permit the foot of a post to fit into the recess of an identically configured post.
