One-Piece Squeeze And Turn Child-Resistant Closure And Container System
A one-piece squeeze and turn child resistant closure for a container having a threaded neck and a top shoulder having a top surface with at least one locking recessed annulus slot or groove, the closure comprising a sidewall of a rigid material, the sidewall further comprising at least one flexible panel wherein, when depressed, allows the unscrewing of the closure from the bottle, wherein each flexible panel includes at least one vertical tab that engages a corresponding locking recessed slot or groove of the container.
Illustrative aspects of the invention relate to child resistant packages such as for pharmaceuticals.
BACKGROUNDU.S. Pat. No. 5,671,853 is directed to a child-resistant one-piece container and one-piece closure assembly.
There is a need for an improved one-piece squeeze and turn child-resistant one-piece container. There is a further need to provide a two-piece package with no third component. There is further a need to eliminate sharp edges from standing injection molded tabs.
SUMMARYA first aspect of the invention is directed to a one-piece squeeze and turn child resistant closure for a container.
A second aspect is directed to a child resistant package comprising a container and a one-piece squeeze and turn child resistant closure for the container.
Illustrative aspects of the present invention will be described. These aspects merely provide examples of the invention, and it is needless to say that the aspects can be suitably modified without departing from the gist of the invention.
Aspects of the invention include a child resistant package including a one-piece squeeze and turn child resistant closure of rigid or stiff material. As shown in
As shown in
The sidewall 3 typically has an outside diameter to match the outside diameter of the bottle. The closure and tabs may have stiffening ribs 14 and 15 as shown in
The cap can be used on an easy-grip bottle having finger grips 17 such as shown in
Aspects of the invention further include an optional plug seal ring 16 for “liquid tight” requirements and/or elimination of costly induction foil seals. However, liners with a foil seal may also be applied if desired.
The one-piece squeeze and turn closure is senior friendly. The present invention eliminates standing lugs with sharp edges by using recessed slots 13, eliminates angled sidewalls, and allows sleek vertical sidewalls to increase the top surface for better stacking of packages.
The shape of the closure and container provides a better store presence as the shape is maintained from the very bottom of the package to the very top. The package is also department store friendly since stores prefer packages that are easily stackable. Aspects of the invention further include optional stacking ring in top of closure to help with stacking.
The packages may be used for pharmaceuticals such as tablets and liquids. The packages may be used for holding other items as well.
While the various aspects of the invention have been described in conjunction with the example structures and methods described above, various alternatives, modifications, variations, improvements and/or substantial equivalents, whether known or may be presently unforeseen, may become apparent to those having at least ordinary skill in the art. Accordingly, the example structures and methods, as set forth above, are intended to be illustrative of the invention, not limiting it. Various changes may be made without departing from the spirit and scope of the invention. Therefore, the invention is intended to embrace all known or later developed alternatives, modifications, variations, improvements and/or substantial equivalents
Claims
