Abstract
Abstract A child-proof container (1) comprising a box (2) and a casing (3), in which the box is insertable, whereby the opening of the box is prevented by means of catch members (4), which in unloaded condition project a small distance into the box from the inner side of one of the flat side surfaces (3a) of the casing, whereby said side of the casing is flexible under influence of side forces (A) acting against each other for raising the catch members above the box (2). (FIG. 1).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
260 words
In a child-proof container of the type comprising a drawer which is slidably displaceable in a casing having at least one of its flat side walls made from a material which is flexible in the latitudinal direction and on the inside of said one flat side wall is provided with catch means extending therefrom towards the interior of the casing, the improvement wherein the casing comprises a tubular member which has a rectangular cross-section and is open a both ends, the catch means comprises at least two, spaced apart cam members located one near each one of the open ends of the casing and extending towards the interior thereof a distance exceeding the normal play between the casing and drawer, said cam members each having a substantially flat outer face inclined from said one flat side wall of said casing toward the adjacent open end and a substantially flat end face extending from and substantially perpendicular to said one flat side wall a distance sufficient to extend inside the edge of the adjacent end wall of the drawer when in the closed position thereby preventing unintentional opening of the container, and to release said edge to allow the drawer to be slidingly displaced to the open position by outward bending of said one flat side wall of the casing caused by forces acting toward said casing and substantially perpendicularly to the displacement direction of the drawer, the flat outer inclined face of the other cam member engaging said released edge to resist complete removal of said drawer from said casting.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
61 words
A child-proof container according to claim 1, characterized thereby, that the catch members (4) of the casing (3) consist of cams fitted to the inner side of said one flat side wall (3a, 13a) of the casing and each one having an inclined surface (4a), which gives the cam diminishing height in a direction away from the associated casing short side.
Claim 4
Dependent Claim
34 words
A child-proof container according to claim 1, wherein said cam members of the casing comprise material tabs bent out of said one flat side wall of the casing towards the interior of the casing.
Claim 5
Dependent Claim
42 words
A child-proof container according to claim 1 wherein said drawer has an open upper side and said cam members are disposed on the inside of the upper side of said casing and extend into said drawer from the open upper side thereof.
Claim 6
Dependent Claim
37 words
A child proof container according to claim 1 wherein said cam members are disposed on the inside of the bottom side wall of the casing, and stop members are provided on the bottom side of said drawer.
Claim 7
Dependent Claim
26 words
A child-proof container according to claim 5, wherein said stop members comprise recesses in the bottom side of said drawer which interengage with said cam members.
Claim 8
Dependent Claim
19 words
A child-proof container according to claim 6, wherein said recesses are slots extending through the bottom of said drawer.
Claim 9
Dependent Claim
41 words
A child-proof container according to claim 5 wherein the bottom of the drawer is offset a distance above the lower edges of its end walls, and said lower edges of the end walls situated below said bottom comprise said stop members.
Claim 10
Dependent Claim
35 words
A child-proof container according to anyone of the preceding claims, wherein the longitudinal side walls of the casing slightly diverge in the direction toward the said one flat side wall provided with said cam members.
