Claim 3

A safety closure as claimed in claim 1 wherein said latch portions are posts extending from said wall portion with each post having an overhanging lug.

Claim 4

A safety closure as claimed in claim 1 wherein each catch means comprises an arcuately shaped resilient portion connected at one end to the overcap and having projecting catch portions on the other end adapted to engage with one of said latch portions.

Claim 5

A safety closure as claimed in claim 1 wherein said latch portions are spaced apart an amount too wide for a child''s digit but just enough to permit an adult digit to bridge therebetween and to contact both catch portions at the same time.

Claim 6

A safety closure for a container having a spout, an overcap having a plug for sealing engagement in said spout, said overcap being hingedly carried by said container adjacent said spout, and means for latching said overcap in said sealing engagement, said means comprising a pair of spaced apart projecting latch portions carried by said container, a pair of spaced apart catch means carried by said overcap and extending into latching position with said latch portions, tab means on said overcap extending outwardly between said pair of catch means a distance less than the extension of said catch means whereby, to unseal said spout, both of said catch means must be simultaneously disengaged from said latch portions before the tab means can be urged upward iNto unsealing relation with respect to said spout.

Claim 7

A safety closure for a container having a spout, an overcap having a plug for sealing engagement in said spout, said overcap being hingedly carried by said container adjacent said spout, and means for latching said overcap in said sealing engagement, said means comprising a pair of spaced apart projecting latch portions carried by said container, a pair of spaced apart catch means carried by said overcap and extending into latching position with said latch portions, tab means on said overcap extending outwardly between said pair of catch means a distance less than the extension of said catch means whereby, to unseal said spout, both of said catch means must be simultaneously disengaged from said latch portions before the tab means can be urged upward iNto unsealing relation with respect to said spout.

Claim 8

A safety closure as claimed in claim 5 wherein said container has a restricted neck portion and said closure has a wall portion and a depending skirt portion with the skirt portion engaging the neck portion of the container and the wall portion having the spout upwardly projecting therefrom, and wherein said overcap is hinged to said wall portion and said latch portions are carried by said closure on the side opposite to the side to which the overcap is hinged.

Claim 9

In a fluid dispensing device comprising a container having a narrowed neck portion and a primary closure attached to said container, said primary closure having a wall portion with a dispensing spout upwardly extending therefrom, a skirt portion depending from said wall portion and engaging with said neck portion of said container, a secondary closure having a plug means for sealing engagement in the spout, hinge means on said secondary closure and on said wall portion for hingingly mounting said secondary closure to said wall portion, and means for latching said secondary closure to said wall portion, said last named means comprising a pair of spaced apart members carried by said primary closure on a diametrically opposite side of said primary closure from said hinge means, said members having overhanging portions thereon, a pair of spaced apart catch means carried by said secondary closure and extending into latching relation with said overhanging portions on said members, tab means on said secondary closure extending outwardly between said pair of catch means only a part of the outward extension of the catch means whereby, to unseal said secondary closure from said spout, both catch means must be disengaged from said members before the tab means can be lifted.

Claim 10

In a fluid dispensing device comprising a container having a narrowed neck portion and a primary closure attached to said container, said primary closure having a wall portion with a dispensing spout upwardly extending therefrom, a skirt portion depending from said wall portion and engaging with said neck portion of said container, a secondary closure having a plug means for sealing engagement in the spout, hinge means on said secondary closure and on said wall portion for hingingly mounting said secondary closure to said wall portion, and means for latching said secondary closure to said wall portion, said last named means comprising a pair of spaced apart members carried by said primary closure on a diametrically opposite side of said primary closure from said hinge means, said members having overhanging portions thereon, a pair of spaced apart catch means carried by said secondary closure and extending into latching relation with said overhanging portions on said members, tab means on said secondary closure extending outwardly between said pair of catch means only a part of the outward extension of the catch means whereby, to unseal said secondary closure from said spout, both catch means must be disengaged from said members before the tab means can be lifted.

Claim 11

A safety closure for a container having a spout, an overcap covering said spout, and means for holding said overcap in sealing engagement with respect to said spout, said means comprising stationary means carried by said container having a contacting surface, a pair of spaced apart means carried by said overcap and extending into engaging relationship with said stationary means, a pair of spring-like members connected to said spaced apart means, tab means on said overcap extending between said pair of spring-like members whereby to unseal said spout both of said spring-like members must be simultaneously deflected to misalign said spaced apart means from said stationary means.

Claim 12

A safety closure for a container having a spout, an overcap covering said spout, and means for holding said overcap in sealing engagement with respect to said spout, said means comprising stationary means carried by said container having a contacting surface, a pair of spaced apart means carried by said overcap and extending into engaging relationship with said stationary means, a pair of spring-like members connected to said spaced apart means, tab means on said overcap extending between said pair of spring-like members whereby to unseal said spout both of said spring-like members must be simultaneously deflected to misalign said spaced apart means from said stationary means.
