Abstract
Abstract A safety closure for a container, which also provides a hermetic seal, is formed by a cap which fits downwardly over the neck portion of the container. The neck has a horizontally arranged annular groove formed at its lower end and at least one vertical groove extends downwardly on the outer surface of the neck to the horizontal groove. The cap member is provided with a spring and sealing means on its inner surface and it also contains a tooth or projection which fits into the vertical groove of the neck as the cap is placed on the container and passes downwardly to the horizontal groove where it is rotated into a spaced position from the vertical groove and fits within a notch for locking the cap onto the neck of the container. In the locked position the spring and sealing means within the cap are biased against the opening in the upper end of the neck for providing the hermetic seal.

Claim 1
Independent Claim
476 words
A container provided with a safety hermetic seal cap comprises first walls defining a container space extending vertically in its normal position and an upwardly extending neck forming an opening into said container space, a horizontally disposed annular-shaped continuous groove is formed in the exterior surface of said neck at its lower end, the upper horizontally disposed surface of said horizontal groove forming a planar shoulder, at least one vertically extending open ended groove formed in the outer surface of said neck and extending from the upper end of said neck to said groove, an upwardly extending notch formed in said shoulder within said horizontal groove at a position spaced from the lower end of said vertical groove, said notch extending vertically upwardly from said shoulder and having a vertical dimension less than the vertical dimension of said vertical groove, the horizontal dimension of said groove is similar to the horizontal dimension of said vertical groove, a horizontally arranged cover disc and a skirt extending downwardly from said cover disc defines the cap which is positioned vertically in its normal position on the container and forms a cavity of a sufficient height and shape to contain the portion of said neck extending upwardly from said shoulder, a helical compression spring secured within the cavity to the lower surface of said disc and depending downwardly therefrom, a retainer member fixed to the lower end of said spring, a packing ring fixed to the lower surface of said spring retainer member and being of a sufficient size to form a closure for hermetically sealing the opening in said neck, at least one tooth secured to and extending inwardly from the lower edge of said skirt, said tooth having a vertical dimension which is less than the vertical dimension of said horizontal groove and a horizontal dimension and shape such that it can fit within and pass downwardly through said vertical groove in said neck, the vertical dimension between said packing ring and the upper surface of said tooth when the cap is removed from the container is less than the vertical dimension of said neck from its upper end to said shoulder in said groove so that when the cap is assembled on said neck the upper end of said neck compresses said spring so that said packing ring effects a seal for the opening from said neck and said tooth passes downwardly through said vertical groove and then is rotated to and seated within said notch for holding the cap on the container against accidental displacement and to achieve this effect the vertical dimension between the upper surface of said notch and the upper end of said neck is greater than the vertical dimension between the upper surface of said tooth and the lower surface of said packing ring when the cap is in the dissembled position.

Dependent Claim

A container provided with a safety hermetic seal cap comprises first walls defining a container space extending vertically in its normal position and an upwardly extending neck forming an opening into said container space, a horizontally disposed annular-shaped continuous groove is formed in the exterior surface of said neck at its lower end, the upper horizontally disposed surface of said horizontal groove forming a planar shoulder, at least one vertically extending open ended groove formed in the outer surface of said neck and extending from the upper end of said neck to said groove, an upwardly extending notch formed in said shoulder within said horizontal groove at a position spaced from the lower end of said vertical groove, said notch extending vertically upwardly from said shoulder and having a vertical dimension less than the vertical dimension of said vertical groove, the horizontal dimension of said groove is similar to the horizontal dimension of said vertical groove, a horizontally arranged cover disc and a skirt extending downwardly from said cover disc defines the cap which is positioned vertically in its normal position on the container and forms a cavity of a sufficient height and shape to contain the portion of said neck extending upwardly from said shoulder, a helical compression spring secured within the cavity to the lower surface of said disc and depending downwardly therefrom, a retainer member fixed to the lower end of said spring, a packing ring fixed to the lower surface of said spring retainer member and being of a sufficient size to form a closure for hermetically sealing the opening in said neck, at least one tooth secured to and extending inwardly from the lower edge of said skirt, said tooth having a vertical dimension which is less than the vertical dimension of said horizontal groove and a horizontal dimension and shape such that it can fit within and pass downwardly through said vertical groove in said neck, the vertical dimension between said packing ring and the upper surface of said tooth when the cap is removed from the container is less than the vertical dimension of said neck from its upper end to said shoulder in said groove so that when the cap is assembled on said neck the upper end of said neck compresses said spring so that said packing ring effects a seal for the opening from said neck and said tooth passes downwardly through said vertical groove and then is rotated to and seated within said notch for holding the cap on the container against accidental displacement and to achieve this effect the vertical dimension between the upper surface of said notch and the upper end of said neck is greater than the vertical dimension between the upper surface of said tooth and the lower surface of said packing ring when the cap is in the dissembled position.
Claim 3
Dependent Claim
142 words
A container, as set forth in claim 1, wherein said neck has a frustoconical shape diverging downwardly from its upper end to said shoulder defining the upper surface of said horizontal groove, a pair of said vertical grooves disposed on diametrically opposite sides of said neck, the cavity in the cap having a frustoconical shape similar to and slightly larger than that of said neck so that the cap fits downwardly over said neck, a pair of said teeth disposed on diametrically opposite sides of said neck, and a pair of said notches disposed on diametrically opposite sides of said neck spaced angularly at 90* from said vertical grooves for receiving and holding said teeth in the locked position of the cap on the container when the cap is rotated through said horizontal groove until said teeth are aligned with said notches.
