Dispensing closure with child resistant feature
View Patent ↗A dispenser closure is provided having an upper wall portion with at least one opening therein and having a thread depending from an inner annular surface thereof. A lower wall portion of the closure has at least two lugs depending from a lower inner annular surface thereof having a configuration and size to cooperate with at least one stop lock depending from a container neck and at least one of the cooperating closure lugs does not cooperate with the cooperating stop lock when the lower wall portion is deformed by a squeezing force.
1. A dispensing closure comprising:
a dispensing closure having at least one dispensing aperture defined by a top wall of said closure, said closure threadably engagable with a container, said container having a container neck defining an opening surrounded by a rim, a pair of opposing stop locks projecting from said container neck and positioned at about 180° from each other;
said closure having a deformable outermost skirt depending from said top wall, said outermost skirt having an interior surface and an exterior surface;
at least two rotational stop lugs spaced about said interior surface of said outermost skirt at about 180° from each other, and at least two child resistant lugs projecting from said interior surface of said outermost skirt and spaced about said interior surface of said outermost skirt at about 90° from each of said rotational stop lugs;
each of said stop lugs positioned at a first radial distance and each of said child resistant lugs positioned at a second radial distance, wherein said first radial distance is substantially the same as said second radial distance;
each of said rotational stop lugs positioned proximate a lower edge of said outermost skirt and each of said child resistant lugs are offset at a distance away from said lower edge of said outermost skirt said at least two child resistant lugs operably engaging said stop locks of said container neck upon initial counterclockwise rotation of said closure on said container and wherein inward pressure adjacent each of said rotational stop lugs causes said outermost skirt to deflect allowing each of said child resistant lugs to override said stop locks and, each of said rotational stop lugs operably engage said stop locks of said container to prevent continued counterclockwise rotation of said closure on said container and further inhibits removal of said closure from said container since each of said rotational stop lugs do not release contact with said stop locks when inward pressure is applied to said outermost skirt adjacent each of said child resistant lugs; and
said dispensing closure is non-removable.
2. The dispensing closure of claim 1 wherein each one of said two rotational stop lugs project further from said interior surface of said outermost skirt than each one of said two child resistant lugs.
3. The dispensing closure of claim 1 wherein said exterior surface of said outermost skirt has a squeeze guide proximate each of said at least two rotational stop lugs.
4. The dispensing closure of claim 1 wherein said closure thread projects from said interior surface of said outermost skirt.
5. The dispensing closure of claim 1 wherein said top wall is dome like in shape.
6. The dispensing closure of claim 1 wherein said top wall has a plurality of said at least one dispensing apertures.
7. The dispensing closure of claim 1 is a single wall closure.
8. The dispensing closure of claim 1 wherein said outermost skirt is an outer wall of a double wall closure.
9. The dispensing closure of claim 1 further including a sealing post operably engaging said at least one dispensing aperture of said top wall.
10. The dispensing closure of claim 1 wherein said closure thread is in a cooperating position with a container thread depending from an outer annular surface of said container neck at least until such time that said at least two rotational stop lugs abut said pair of opposing stop locks of said container neck and, said pair of opposing stop locks of said container neck are positioned so that said at least two child resistant lugs are sufficiently adjacent a locking side of said pair of opposing stop locks when said closure is in a tightened position on said container neck so that a sealing post connected to an upper end of said container neck seals said at least one dispensing aperture in said closure and said sealing post seals said at least one dispensing aperture during initial counterclockwise rotation of said closure at least until said at least two child resistant lugs are oriented to make initial contact with said pair of opposing stop locks of said container neck and, said sealing post is withdrawn from said at least one dispensing aperture when said at least two rotational stop lugs abut said pair of opposing stop locks.
11. A closure and container combination comprising:
a closure being a non-removable closure threadably engaging a container neck of a container, said container neck projecting at least one stop lock;
said closure having a top wall with at least one opening therein, a deformable outermost skirt depending from said top wall; and
an interior surface of said outermost skirt having at least one child resistant lug and at least one rotational stop lug projecting inwardly therefrom at an annular position having substantially the same radial distance from the central axis of said closure, said at least one rotational stop lug positioned more proximate a lower edge of said outermost skirt than each one of said at least one child resistant lugs, a squeeze guide positioned on an outside surface of said closure outermost skirt adjacent each of said at least one rotational stops, said at least one child resistant lug operably engaging said at least one stop lock of said container neck upon initial counterclockwise rotation of said closure on said container and wherein said at least one child resistant lug overrides at least one stop lock of said container neck when a squeezing force is placed on said squeeze guide of said outermost skirt, said at least one rotational stop lug operably engages said at least one stop lock of said container neck to prevent continued counterclockwise rotation of said closure on said container and further inhibits removal of said closure from said container since said at least one rotational stop lug remains in contact with said at least one stop lock of said container neck when said squeezing force is placed on said outermost skirt adjacent said at least one child resistant lug.
12. The closure and container combination of claim 11 wherein said at least one child resistant lug and said at least one rotational stop lug are spaced less than 180° from each other about said interior surface of said outermost skirt.
13. The closure and container combination of claim 11 wherein said outermost skirt projects two of said at least one child resistant lugs spaced at about 180° from each other and two of said at least one rotational stop lugs spaced about 90° from each of said child resistant lugs.
14. The closure and container combination of claim 11 wherein said at least one rotational stop lug projects further from said interior surface of said outermost skirt than said at least one child resistant lug.
15. The closure and container combination of claim 11 wherein said threads of said closure project from said interior surface of said outermost skirt.
16. The closure and container combination of claim 11 wherein said outermost skirt is an outer wall of a double wall closure.
17. The closure and container combination of claim 16 wherein said closure thread projects from an interior surface of an inner wall of said double wall closure.
18. The closure and container combination of claim 11 wherein said top wall has a plurality of said at least one openings.
19. The closure and container combination of claim 11 wherein said closure thread is in a cooperating position with said container thread depending from an outer annular surface of said container neck at least until such time that said at least one rotational stop lug abuts said at least one stop lock of said container neck and, said at least one stop lock of said container neck is positioned so that said at least one child resistant lug is sufficiently adjacent a locking side of said at least one stop lock when said closure is in a tightened position on said container neck so that a sealing post connected to an upper end of said container neck seals said at least one opening in said closure and said sealing post seals said at least one opening during initial counterclockwise rotation of said closure at least until said at least one child resistant lug is oriented to make initial contact with said at least one stop lock of said container neck and, said sealing post is withdrawn from said at least one opening when said at least one rotational stop lug abuts said at least one stop lock of said container neck.
20. A non-removable dispensing closure and container combination comprising:
a dispensing closure threadably engaging a container, said closure including a cap body with a top wall wherein said top wall defines a dispensing orifice therethrough, and a deformable annular outermost skirt depending from said top wall, said annular outermost skirt positioned at a radial distance from the central axis of said closure and includes at least one child resistant lug and at least one rotational stop lug projecting therefrom at said radial distance, said at least one rotational stop lug positioned proximate a lower edge of said outermost skirt and said at least one child resistant lug is offset at a distance away from said lower edge of said outermost skirt;
said annular outermost skirt having said thread projecting therefrom; and
said container including a neck defining an opening surrounded by a rim, said neck having at least one stop lock formed thereon, said at least one stop lock operably engaging said at least one child resistant lug upon initial counterclockwise rotation of said closure on said container and wherein inward pressure on said deformable outermost skirt adjacent said at least one rotational stop lug causes said annular outermost skirt to deflect allowing said at least one child resistant lug to override said at least one stop lock of said container neck, and wherein said at least one rotational stop lug operably engage said at least one stop lock of said container neck to prevent continued counterclockwise rotation of said closure on said container and further inhibits removal of said closure from said container since said at least one rotational lug remains engaged with said at least one stop lock when inward pressure is applied and deforms said outermost skirt.
