Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
118 words
A container for magnetizable articles comprising a closed box shaped casing having a bottom wall, side walls and a top wall defining at least one chamber for the said articles, an opening extending over the whole length of one of the upper edges of the casing, the opening having an upper boundary edge defined by the top wall of the casing and a lower boundary edge defined by the adjacent side wall of the casing, and a guide surface extending from the lower boundary edge to said bottom wall, a bar magnet being arranged below the guide surface near the opening whereby the magnetic field of the bar magnet is most powerful in the region of the opening.
Claim 2
Dependent Claim
118 words
A container for magnetizable articles comprising a closed box shaped casing having a bottom wall, side walls and a top wall defining at least one chamber for the said articles, an opening extending over the whole length of one of the upper edges of the casing, the opening having an upper boundary edge defined by the top wall of the casing and a lower boundary edge defined by the adjacent side wall of the casing, and a guide surface extending from the lower boundary edge to said bottom wall, a bar magnet being arranged below the guide surface near the opening whereby the magnetic field of the bar magnet is most powerful in the region of the opening.
Claim 3
Dependent Claim
33 words
A container according to claim 1 wherein the guide surface extends from the lower boundary edge of the opening to a point approximately in the center of the bottom wall of the casing.
Claim 4
Dependent Claim

A container according to claim 1 wherein the guide surface includes a curved portion in the form of a circular segment the center of curvature of which is located at the lower edge of the casing below said opening, and an inclined portion merging at one end into the curved portion and at its other end into the bottom wall.
Claim 5
Dependent Claim
29 words
A container according to claim 1 wherein the side walls of either side of the opening are each provided with an arcuate recess in the region of the opening.
Claim 6
Dependent Claim
58 words
A container according to claim 1 a plurality of adjacent chambers are arranged within the container casing, said chambers being separated by at least one dividing wall, and each chamber including an opening, a curved guide surface extending from the respective opening towards the respective container interior, and a bar magnet arranged below each of said guide surfaces.
Claim 7
Dependent Claim
13 words
