Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
A safety receptacle or enclosure for hazardous materials of the character described for preventing access by small children to contents which comprises, in combination, a main container body having a peripheral wall and a bottom, said wall having a closure-receiving upper sealing rim around its opening, a capsimulating ring secured to said container and surrounding but annularly spaced from said upper rim, first locking elements on the container body disposed between said ring and said peripheral wall, an upper carrier cap member having dependent locking elements adapted to engage cooperatively with said first locking elements by relative rotational movement, said cooperative locking elements including means for positively blocking said elements against said relative rotational movement, and resilient means associated with the carrier cap member for urging said carrier cap away from the said upper rim of the main container body, thereby forcibly holding the locking elements in locked and blocked position, said resilient means being of such strength and resilience as to apply an urging force greater than that which a small child is physically capable of overcoming.
Claim 2
Dependent Claim
178 words
A safety receptacle or enclosure for hazardous materials of the character described for preventing access by small children to contents which comprises, in combination, a main container body having a peripheral wall and a bottom, said wall having a closure-receiving upper sealing rim around its opening, a capsimulating ring secured to said container and surrounding but annularly spaced from said upper rim, first locking elements on the container body disposed between said ring and said peripheral wall, an upper carrier cap member having dependent locking elements adapted to engage cooperatively with said first locking elements by relative rotational movement, said cooperative locking elements including means for positively blocking said elements against said relative rotational movement, and resilient means associated with the carrier cap member for urging said carrier cap away from the said upper rim of the main container body, thereby forcibly holding the locking elements in locked and blocked position, said resilient means being of such strength and resilience as to apply an urging force greater than that which a small child is physically capable of overcoming.
Claim 3
Dependent Claim
43 words
A receptacle or enclosure according to claim 1 which includes an inner sealing cap or plug element supported by the carrier cap and adapted to engage said upper rim of the container body with effective sealIng force when said locking elements are interengaged.
Claim 4
Dependent Claim
45 words
A receptacle or enclosure according to claim 1 in which an inner sealing cap or plug is mounted in compressible resilient relationship with respect to the carrier cap member, said cap or plug comprising resilient means which produce the holding force for the locking elements.
Claim 5
Dependent Claim
60 words
A receptacle or enclosure according to claim 1 which includes a web element securing the cap-simulating ring firmly to the main container body, a plurality of locking slots in the form of bayonet openings being set in said web element, and a hook means on said dependent locking elements for engaging a web under-surface adjacent each of said bayonet openings.
Claim 6
Dependent Claim
55 words
A receptacle or enclosure according to claim 4 in which the bayonet slots comprise multiple surfaces for engagement with the hook means, said multiple surfaces including a vertical surface adapted positively to prevent relative rotational movement between the hook means and said bayonet slots when the hook means are engaged with said web under surfaces.
Claim 7
Dependent Claim
73 words
A receptacle or enclosure according to claim 4 in which the bayonet slots are each bounded by a peripheral surface and an under locking surface, said web element also including a vertical surface for positively preventing rotational movement of the hooks for disengagement with said slots, and wherein the resilient means holds the hook and bayonet slot elements parts in locking engagement with an urging force greater than a small child can overcome.
Claim 8
Dependent Claim
66 words
A receptacle or enclosure according to claim 1 which includes a sealing element supported by the carrier cap and in which the resilient urging force to be overcome for unlocking the receptacle is applied to respective annular areas of small radius on the carrier cap and the sealing element to limit the torque force required for turning the carrier cap with respect to the sealing element.
Claim 9
Dependent Claim
93 words
A safety receptacle or enclosure according to claim 1 in which the main container body is circular in horizontal section and which comprises an integral annular web connecting the cap-simulating ring with the main container body, a series of bayonet slots each having respectively wider and narrower slot portions, an equal number of hook elements dependent from and integral with said carrier cap, each hook being adapted to move freely into and out of the wider slot portion but to be locked to the web when moved rotatively into the narrower slot portion.
Claim 10
Dependent Claim
54 words
A safety receptacle or enclosure according to claim 8 in which vertical locking surfaces on the annular web are positioned to positively prevent relative rotational movement between the hook elements and the narrower slot portions unless the carrier cap is moved towards the main container body with sufficient force to overcome said urging force.
Claim 11
Dependent Claim
66 words
A safety receptacle or enclosure according to claim 9 wherein an inner sealing element is carried by the carrier cap to engage the main container upper rim firmly when said hooks are engaged in said narrower slot portions, said carrier cap and said sealing element bearing respectively opposing and similar annular bearing areas of substantially smaller radius than the circular section of the main container body.
