Abstract

A safety closure comprising a cap threaded on a neck. The neck includes an upwardly biased safety button which seats in a notch on the lower edge of a cap screw. The safety button is seated in the notch and prevents turning of the cap and thereby removal of the latter from the neck until the button is depressed and disengaged from the notch.

BAGGULEY THREADED SAFETY CLOSURE BACKGROUND OF THE INVENTION The present invention relates to child proof closures and more particularly to a closure structure requiring a combination of linear and rotary movements performed in a sequence to remove the closure.
The closure of the present invention is intended for use with containers having dangerous or poison products therein. 7
SUMMARY OF THE INVENTION out of the notch to allow unthreading of the cap from the neck.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a fragmentary perspective view of a closure embodying the structure of the present invention;
FIG. 2 is an elevational view of the closure showing the cap locked on the neck;
FIG. 3 is a longitudinal cross sectional view of the closure showing the cap in the locked position; and
FIG. 4 is a longitudinal cross sectional view of the closure showing the cap in the unlocked position so as to be free for unthreading.
DESCRIPTION OF THE PREFERRED EMBODIMENT Turning now to the drawings there is shown a closure which is adapted to be attached to a container 11. The closure 10 comprises generally a tubular neck 22 and a cap 13. The neck 12 and cap 13 may be made from plastic and molded by injection molding or the like.
The tubular neck 12 includes a circumferential groove 14 spaced slightly above the lower end. The
groove 14 is adapted to receive the curled lip 15 surrounding an opening 16 in the end closure 17 of a container. A horizontal annular flange 18 projects from the neck 12 at a location spaced above the circumferential groove 15.
A helical screw thread 19 is formed about the exterior of the neck 12 and terminates at its lower end above the annular flange. 18. Engaging the external threads are internal threads 21 formed on the interior of a skirt depending from a top 23.
A push or safety button 24 is formed in the annular flange 18. The safety button 24 is defined by a substantially U-shaped slot 25 including a bight 27 and two legs 26. The portion of the button lying between the terminal ends of the slot legs 26 is of lesser thickness than the remainder of the flange to impart the resiliency thereto. The button 24 at the end adjacent to bight 27. is formed with a raised projection 28.
The raised projection 28 normally seats in a notch 29 f din ef ed ofth skirt22.I thi man r, tfi i 13 1 s hId aga i nst rot ation so tha t it annoi be unthreaded from the neck 12.
To unthread the cap 13, the button 24 is depressed downwardly so as to displace the projection 28 out of the notch 29. The cap 12 is then free to be rotated so that it may be unthreaded from the neckl2 as shown in FIG. 4.
The cap 13 is replaced by threading on the neck 12 until the notch 29 overlies the button projection 28. The resiliency of the button causes the latter to seat in the notch 29 so that the cap is prevented from turning in either direction. In this manner, the cap 13 is latched against removal.
What is claimed is:
1.-A safety closure for a container comprising a tubular neck having a flange adjacent the lower end thereof, a cap including a skirt threadably secured on said neck, notch means formed in the free edge of said skirt, and a resilient button defined by a substantially U-shaped slot formed in the flange and located beneath the free edge of said skirt and engageable therein when said cap is threaded on said neck.

Claims (1)

1. A safety closure for a container comprising a tubular neck having a flange adjacent the lower end thereof, a cap including a skirt threadably secured on said neck, notch means formed in the free edge of said skirt, and a resilient button defined by a substantially U-shaped slot formed in the flange and located beneath the free edge of said skirt and engageable therein when said cap is threaded on said neck.
