Abstract

Abstract An all-plastic safety container has a hollow plastic wall with a continuously closed inner surface terminating at a pair of openings; one for venting and filling, and one for pouring. An integral, upstanding, thickened fin and handle combination formed on the outside surface of the container, facilitates the attachment of trigger controlled, safety cap linkage and hardware to the can, without breaking through the inner surface. Yet, the container and its handle are mechanically strong enough to withstand severe usage and to life heavy weights.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 134 words
A safety container comprising an all plastic wall having a continuously closed inner surface except for a pair of longitudinally Displaced upstanding cylindrical tubes with openings therein, a handle and fin combination integrally formed between said tubes and upstanding upon the top outer surface of said wall, cover means over the tubes for closing each of said openings, a trigger controlled sliding linkage means attached to said fin without breaking through said inner surface for selecti-vely controlling the cover means for opening and closing said openings, and said sliding linkage means comprising a plastic piece part having a pair of spaced parallel linkage arms with each linkage arm fitting against opposite sides of said fin and attached to said fin by elongated mounting slots fitting over the ends of rivets passing through said fin.
Claim 2
Dependent Claim 134 words
A safety container comprising an all plastic wall having a continuously closed inner surface except for a pair of longitudinally Displaced upstanding cylindrical tubes with openings therein, a handle and fin combination integrally formed between said tubes and upstanding upon the top outer surface of said wall, cover means over the tubes for closing each of said openings, a trigger controlled sliding linkage means attached to said fin without breaking through said inner surface for selecti-vely controlling the cover means for opening and closing said openings, and said sliding linkage means comprising a plastic piece part having a pair of spaced parallel linkage arms with each linkage arm fitting against opposite sides of said fin and attached to said fin by elongated mounting slots fitting over the ends of rivets passing through said fin.
Claim 3
Dependent Claim 57 words
The container of claim 1 wherein the cover means at one of said openings is closed by a pivoted cap and the cover means at the other of said openings is closed by a spring-biased valve, and said sliding linkage has proportions which open and close said cover means at said two openings in a predetermined sequence.
Claim 4
Dependent Claim 179 words
A safety container comprising an all-plastic wall having a continuously closed inner surface except for a pair of longitudinally displaced upstanding cylindrical tubes with openings therein, a handle and fin combination integrally formed between said tubes and upstanding upon the top outer surface of said wall, cover means over the tubes for closing each of said openings, said cover means at one of said openings comprising a pivoted cap, the cover means at the other of said openings comprising a spring biased valve, a trigger controlled sliding linkage means attached to said fin without breaking through said inner surface for selectively controlling the cover means for opening and closing said openings, said sliding linkage means dimensioned to open and close said cover means at said two openings in a pre-determined sequence, and said sliding linkage means comprising a plastic piece part having a pair of spaced parallel linkage arms with each linkage arm fitting against opposite sides of said fin and attached to said fin by elongated mounting slots fitting over the ends of rivets passing through said fin.
Claim 5
Dependent Claim 179 words
A safety container comprising an all-plastic wall having a continuously closed inner surface except for a pair of longitudinally displaced upstanding cylindrical tubes with openings therein, a handle and fin combination integrally formed between said tubes and upstanding upon the top outer surface of said wall, cover means over the tubes for closing each of said openings, said cover means at one of said openings comprising a pivoted cap, the cover means at the other of said openings comprising a spring biased valve, a trigger controlled sliding linkage means attached to said fin without breaking through said inner surface for selectively controlling the cover means for opening and closing said openings, said sliding linkage means dimensioned to open and close said cover means at said two openings in a pre-determined sequence, and said sliding linkage means comprising a plastic piece part having a pair of spaced parallel linkage arms with each linkage arm fitting against opposite sides of said fin and attached to said fin by elongated mounting slots fitting over the ends of rivets passing through said fin.
Claim 6
Dependent Claim 39 words
The container of claim 3 wherein one end of said linkage arms operates a closure means over one of said openings before the other end of said linkage arms operates a closure means over the other of said openings.
Claim 7
Dependent Claim 40 words
The container of claim 4 wherein said arms have an upstanding trigger thereon positioned in relation to said handle so that said linkage arms may be slid without requiring the user to shift or loosen his grip on the handle.
Claim 8
Dependent Claim 22 words
The container of claim 5 wherein said trigger is positioned to be operated by a squeeze of a hand holding the handle.
Claim 9
Dependent Claim 198 words
A safety container comprising an all-plastic wall having a continuously closed inner surface except for a pair of longitudinally displaced upstanding cylindrical tubes with openings therein, a handle and fin combination integrally formed between said tubes and upstanding upon the top outer surface of said wall, cover means over the tubes for closing each of said openings, one of said cover means comprising a cap lifted by an L-shaped bracket pivotally connected to said container, the other of said cover means comprising a spring biased valve enclosed within a valve body, said sliding linkage means comprising a piece part having a pair of spaced, parallel linkage arms with said arms fitting against opposite sides of said fin, one end of said sliding linkage being positioned to engage said L-shaped bracket and the other end of said sliding linkage being positioned to control said valve, said linkage having a length whereby said one end operates said L-shaped bracket to lift the cap over one of the said openings before the other end of said linkage operates said valve, and said sliding linkage further including an upstanding integral trigger positioned in said handle to slide said linkagE along said arms.
Claim 10
Dependent Claim 198 words
A safety container comprising an all-plastic wall having a continuously closed inner surface except for a pair of longitudinally displaced upstanding cylindrical tubes with openings therein, a handle and fin combination integrally formed between said tubes and upstanding upon the top outer surface of said wall, cover means over the tubes for closing each of said openings, one of said cover means comprising a cap lifted by an L-shaped bracket pivotally connected to said container, the other of said cover means comprising a spring biased valve enclosed within a valve body, said sliding linkage means comprising a piece part having a pair of spaced, parallel linkage arms with said arms fitting against opposite sides of said fin, one end of said sliding linkage being positioned to engage said L-shaped bracket and the other end of said sliding linkage being positioned to control said valve, said linkage having a length whereby said one end operates said L-shaped bracket to lift the cap over one of the said openings before the other end of said linkage operates said valve, and said sliding linkage further including an upstanding integral trigger positioned in said handle to slide said linkagE along said arms.
Claim 11
Dependent Claim 12 words
The container of claim 7 wherein said piece part is all plastic.
