Abstract
This invention provides a tubular container body and closure assembly with a smooth or flush outside surface. The assembly is provided with bayonet type child resistant closure and tear away tamper resistant band. The container body has a recess to receive a teartab on the tear away band so that the flush outside surface is maintained, the recess in the body being so positioned that when the tear tab is aligned with the recess an internal bead on the closure forming part of the bayonet type locking arrangement is aligned with an external locking slot on the body so that the closure can be applied to the body by a longitudinal downward movement.
Claims15
A tubular child-resistant and tamper-resistant container, comprising:
- a container body having an open mouth, a longitudinal axis and a side wall with inner and outer surfaces;
- bayonet locking slots on said outer surface adjacent said mouth;
- an external recess in said side wall on said outer surface extending downwardly from said mouth and substantially parallel to said longitudinal axis;
- a closure having inside and outside surfaces, bayonet locking beads mating with and forming a bayonet connection with said locking slots on said body and a tear band integrally formed as part of said closure, said tear band having a depending tab shaped to conform to and be received in said recess and located relative to said locking beads such that said locking beads are aligned with and engaged in said locking slots when said tab is aligned with and located in said recess, said locking slots and locking beads being formed such that said closure assembly can be applied to said body to close said mouth by a direct downward movement parallel to said longitudinal axis, said outer surface of said body and outside surface of said closure including said tear band having substantially identical configurations such that the container has a flush exterior surface;
- and
- spring means, between said body and said closure, for holding said closure in a closed position.
A tubular child-resistant and tamper-resistant container, comprising:
- a tubular body having an open mouth, a longitudinal axis and a side wall with inner and outer surfaces;
- a bayonet locking slot on said outer surface adjacent said mouth;
- an external recess in said side wall on said outer surface extending downwardly from said mouth and substantially parallel to said longitudinal axis;
- and
- a closure having inside and outside surfaces, bayonet locking means for mating with and forming a bayonet connection with said locking slot on said body and a tear band integrally formed as part of said closure, said tear band having a depending tab shaped to conform to and be received in said recess and located relative to said locking means such that said locking means is aligned with and engaged in said locking slot when said tab is aligned with and located in said recess, said locking slot and locking means being formed such that said closure assembly can be applied to said body to close said mouth by a direct downward movement parallel to said longitudinal axis.
A tubular child-resistant and tamper-resistant container, comprising:
- a tubular body having an open mouth, a longitudinal axis and a side wall with inner and outer surfaces;
- a bayonet locking slot on said outer surface adjacent said mouth;
- an external recess in said side wall on said outer surface;
- and
- a closure having inside and outside surfaces, bayonet locking means mating with and forming a bayonet connection with said locking slot on said body and a tear band, said tear band having a depending tab shaped to conform to and be received in said recess and located relative to said locking means such that said locking means is aligned with and engaged in said locking slot when said tab is aligned with and located in said recess, said locking slots and locking means being formed such that said closure can be applied to said body to close said mouth by a direct downward movement parallel to said longitudinal axis, said outer surface of said body and outside surface of said closure including said tear band having substantially identical configurations such that the container has a flush exterior surface.
