Abstract

There is disclosed a container and a closure cap screwed onto a threaded neck of the container, in which the cap has an external ratchet and the container has a resiliently displaceable pawl which normally engages the ratchet to preclude rotation of the cap in an opening direction and allows rotation of the cap in a closing direction. The pawl is manually displaceable to be disengaged from the ratchet to allow the closure cap to be removed.

3,101,856 8/1963 Whiteman, Jr. 215/209 11 Claims, 8 Drawing Figures CONTAINER AND CLOSURE CAP This invention is concerned with containers and closure caps for containers and is particularly but not necessarily exclusively, concerned with plastic containers.
The invention is particularly concerned to provide a container and closure cap with special provision for avoiding the inadvertent opening of the closure cap. The most pertinent art of which the applicant is aware is US. Pat. No. 3,445,022 issued May 20, I969 to Cilluffo. Another pertinent patent is 3,744,655 issued July 10, 1973 to NixdorffJr. and yet another is re-issue patent No. Re 27,673, issued June 19. 1973 to Landen. The manner in which the present invention is distinguished from this prior art will be apparent in that the disclosure of Cilluffo includes a complex cap element and those of Landen and Nixdorff include separate elements to the cap container.
In essence, this invention seeks to provide a container and closure cap combination in which the cap has a ratchet, and a pawl element is formed on the container normally to adopt a position for precluding the rotation of the cap in an opening direction but allowing rotation in a closing direction and being shiftable to a position in which it is disengaged from the ratchet and the cap freed for movement in the opening direction.
Embodiments of this invention are illustrated in the accompanying drawings, in which:
FIG. 1 is an elevational view of a part of a'container according to this invention;
FIG. 2 is a part sectional, part elevational view of a cap for the container of FIG. 1;
FIG. 3 is a part clevational, part sectional view of the cap and container of FIGS. 1 and 2 in a secured posi tion; I
FIG. 4 is a view similar to the FIG. 3 view but in a ready to open position;
FIG. 5 is a plan view of a detail of the cap of FIG. 2; FIG. 6 is a plan view ofa part of the container of FIG. 1;
FIG. 7 is a part sectional, part elevational view of a second form of container and cap combination according to this invention; and
FIG. 8 is a plan view of the container of the FIG. 7 combination.
The container of FIG. 1 is molded of plastic and includes a main cylindrical body part I0 and a shoulder region 12 tapering to a cylindrical neck 14. The neck has an external screw thread configuration I6. Projecting upwardly and outwardly from the shoulder portion 12 of the container is a pawl 18 which comprises a blocking portion 20 and a finger rest 22. The purpose and function of the pawl is described in greater detail hereinafter.
Referring now to FIG. 2, the cap comprises a cylindrical skirt depending from a disc-like top wall 32. The interior of the skirt is threaded as at 34 for cooperation with the screw thread 16 of the neck of container I0. Below wall 32 is a liner 36 of conventional form. Projecting radially outwardly from the lower edge of skirt 30 is a flange 38 on which is formed a ratchcd made up of teeth 40. The teeth ofthat ratchet have the same axial thickness as the flange.
The cap may he placed on the neck I4 of container I0 and screwed to a closing position. During rotation of the cap the blocking surface 20 of pawl I8 will ride over the ratchet teeth 40. However, the ratchet would preclude rotation of the cap in an opening direction.
The closed or secured position of the combination is shown in FIG. 3. From that figure it will be seen that the pawl 18 extends through the gap between two adjacent teeth of the ratchet. It is of course to be appreciated that the position of the pawl 18 in FIG. 3 is the unflexed position and that the pawl is designed, or of a material, such that it is sufficiently strong to withstand a normal turning force applied to the cap to turn the cap in an opening direction. However, the pawl is also designed to have flexibility in an axial plane so that it can be easily moved by the application of pressure to the finger rest 22 outwardly and downwardly to the position shown in FIG. 4 in which it is disengaged from the ratchet so that the opening of the container is facilitated.
It is to be appreciated that with containers of which the resistance of the pawl to bending from its normal position under the application of force tending to turn the cap in an opening direction is great, there may well be provided another pawl such as that indicated in 18' in dotted line in FIG. 1. It will be understood that in such an arrangement both pawls are to be disengaged from the ratchet for opening the container. It may also be desirable to use two pawls instead of one since a child would find it rather more difficult to open a container with such a feature since opening requires the bending of each pawl.
Further in a two pawl embodiment it can be arranged that in the closed position of the cap one pawl is disposed fully in the space between two teeth while the other is held by a tooth so as not to extend fully into the space with which it is associated so that a turn of the cap through an angular distance representing one notch or tooth causes the second pawl to fully lock the cap. The advantage of such an arrangement resides in the fact that the teeth may be made larger and of course stronger.
An alternative embodiment of the invention is illustrated in FIGS. 7 and 8. In that embodiment, the cap 50 has a flange 52 projecting radially outwardly beyond the skirt 54 and in an outer and lower edge thereof teeth 56 are formed, the teeth forming a ratchet. It is to be appreciated that in this embodiment the teeth are of lesser axial thickness than the flange. In this arrangement, the pawl 60 of the container is slightly modified and comprises a stem 62 upon which is formed a single ratchet tooth engaging nib 64. Otherwise, the operation of the combination in FIGS. 7 and 8 is largely similar to that of the embodiment in FIGS. 1 through 6.
As a matter of production, it is generally desirable to dispose the pawl on a parting line of the molds in which the container is formed. In this way the removal of the container from the casting molds is facilitated.
What is claimed is:
I. A container and closure cap combination wherein said container comprises an externally threaded cylindrical neck and said cap a correspondingly internally threaded skirt, an outwardly extending llange formed on the skirt, a plurality of ratchet teeth extending around the outer periphery of said flange, a pawl element formed integrally on a shoulder region of said container close to said neck, said pawl clement comprising a stem extending upwardly from said shoulder region in a generally axial plane and normally extending into a space between an adjacent two of said ratchet teeth and including a blocking surface engageable with said teeth and constituting means permitting rotation of said cap in a closing direction and precluding rotation of said cap in an opening direction and further including a finger rest portion extending outwardly beyond said flange, said stem being resilient in a generally axial plane to be movable upon the downward application of finger pressure on said finger rest portion downwardly and outwardly in that plane to an inoperative position disengaged from said ratchet teeth to permit rotation of said cap in an opening direction.
