5 Claims. (Cl. 215--9) This invention relates to locks of the combination type for container covers, whereby to remove thecover from the container it is necessary to rotate the cover in op- ,posite directions to predetermined positions.
The present invention is an improvement upon that disclosed in my prio'r application, Serial No. 751,246, filed July 28, 1958. The invention is intended primarily to prevent the accidental opening of containers such as bottles and jars containing poisons or harmful drugs and the like. A very common occurrence is that of a young also prevents an adult from accidentally opening the container by making it somewhat difficult to open and requiring him to read the directions for opening it, which may be given somewhere on the container or cover.
The invention also provides a tight seal between the container and the cover so as to prevent leakage of the contents, if in liquid form, by providing means for pulling the cover down onto the container much as in the manner of the ordinary screw-on cover.
These results are obtained by means of a novel form of container neck, and a novel cover, together with one or more resilient locking rings which require that the cover be rotated back and forth to predetermined positions before the cover can be removed. Also, means is provided for screwing, or camming the cover onto the container tightly enough to prevent leakage of the contents.

' Figure 5 is a cross-sectional View taken on substantially the line 55 of Figure 4, but showing the locking rings in place and looking in the direction of the arrows;

Figure 7 is a cross-sectional view taken on substantially the line 77 of Figure 4 but showing the lo'cking 2,947,431 Patented 2 container 10, acover 11, two locking rings 12 and 13, and a seal 14. l
The container may be fashioned from .any suitable material such as glass or plastic. It has a body portio'n 1'5 having an opening therein surrounded by an annular wall or neck 16. Partially surroundingthewall 16 are rings in place and looking in the direction of the arrows;
and
Figure 8 is a fragmentary elevational view of the contamer and cover showing the indicia of the combination lock.
Referring now to the drawings in more detail, 1116 parts of the container cover lock assembly" consist of a ribs 17, 18 and 19 extending in a circumferential direction and forming grooves 21 and 22 between them, and also a groove 23 below the rib 19. i The ribs are interrupted in a plurality of places to form groups of registering gaps 20' extendingthrough the ribs. Preferably there are three of these groups of gaps. (See Figure 2.) The grooves Hand 22 are'als o interrupted at spaced apart intervals between 'each group of gaps by lands 24, which definea segme nt of a cylindrical surface flush with theouter periphery of the ribs 17, 18 and 19, and shaped as shown in Figure 1. These lands form stops 25 and 26 between ribs 18 and 19, and
stops 27 and 28 between ribs 17 and 18.
Thelower surface of rib 17 also has a downwardly inclined helical portion 29 ending in a horizontal portion 30 adjacent to the stop 28. h
The cover 11 has an annular wall surrounding the neck of the container. Formed in the interior ofthe wall 31 are two circumferential grooves 32 and .33. The groove 33 is circular, while groove 32 is somewhat of a spiral so as to form a shoulder 34. i i
Seated in the grooves 32 and 33- are two resilient rings 12 and 13. Preferably both rings are identical. These rings are not complete ci'rclesbut are broken-or interrupted at 37 for tworeasons; one being so that the rings can be rotated by the cover in one direction, and the other so that therings can be easily snapped into the grooves 32 and 33. The . rings 12 and 13 have radially inwardly bent detents 38 and 39 respectively, equal in number tothe gaps 20 in the ribs on the container neck. Also they are of such dimensions that they will pass through the gaps when in registry therewithl The annular wall of the cover is also provided at its lower edge with inwardly extending lugs ,40, equal in number and in spacing to the gaps 20 on the container neck 16. They are of such dimensions that they will container that when the cover is rotated first to A,
then ,to B, and finally to C, the lugs 40 and .detents 3.8 and 3 9can be registered with each other and thegaps 20 so that the cover can be removed. i i A V The rings 12 and 13 are placed in their respective grooves in the cover and the cletents 38 and 39 are registered axially with the fixed lugs 40 on the cover '11. The cover may then be placed on the container by moving the cover axially onto the neck on the container, with the detents 38 and 39 and lugs 40 passing through the gaps 20. This position of the cover relative to the container is indicated by registering the letter C on the cover with index mark 41 on the container and pushing the cover onto the container until the lugs 40 are in groove 23 detents 38 are in groove 22 and d'etents 39 are located in groove 21. The cover may then be rotated either in a clockwise or in a counter-clockwise direction. There is sufiicient frictional resistance between the rings lz and '13 and the cover to cause the rings to rotate with the cover until prevented from further rotation by the stops on the container neckj If rotated clockwise, tents 38 first strike stops 26. Continuedrotationfof the eater new? a .49 n e ts .39 pnt with detents 3s; Presently detents 39 engagatii heli- 3 cal portions 29 on the container neck which temporarily stops rotation of ring 13 until one end is picked up by shoulder 34 in groove 32 in the cover. Continued clockwise rotation of the. cover drives detents 39 downunder the helical portions 29 and under the horizontal portions 30 until the detents 3 9. strike stops 23 in grooves 21, whereby further rotation is prevented. The force exerted by the helical portions 29' on the detents 39 pulls the cover down onto the container. and forms an effective seal between the cover 1'1, seal 14 and container 10. The detents 39 are capable of some axial bending to perm-it the detents to contact the stops 28. At the same time the ring 13 is twisted in the groove 32, increasing the friction between the ring and the upper and lower walls of the groove 32 and the ring 13. In this position the lugs 40 and detents 38 and 39 are now all out of registry and the cover cannot be removed until all are again moved into registry with each other and with gaps '20.
By providing the horizontal portions 30, when detents 39 pass by the helical portions and engage said horizontal portions, there will be no tendency for the cover to slip back accidentally and break the seal.
To remove the cover the latter is rotated in a counterclockwise direction. Again there is suflicient friction between the rings 12 and 13 and the cover 11 so that the rings move with the cover until detents 38 strike stops 25. The friction between the ring 13 and the upper and lower side walls of the groove 32 is suflicient to overcome the frictional resistance between the detents 39 and the surfaces 30 and 29 because the ring 13 has been twisted, as mentioned in the preceding paragraph, in the groove .32, and the ring does not resume its normal shape. until the detents 39 move out from under those surfiaces. Rotation of the cover counter-clockwise is continued until index 41 and letter A are aligned. During this movement detents 39 strike stops 27, preventing their movement, and when letter A reaches the index mark, lugs 40 and detents 39 are in registry, but detents '38 are not. The cover is then rotated clockwise to B, during which detents 33 strike stops 26, and when letter B registers with index '41 the lugs 40 and detents 3 8 and 39 are all in registry- The cover is then rotated counterclockwise to C during which time, the detents and lugs remain in registry, and when C reaches the index they are all in registry withgaps 20., The cover may then be lifted from the container.
The cover can always be rotated counter-clockwise continuously because there is no positive drive of the rings 12 and '13 in that direction, asby the shoulder 34. Once the detents have contacted their respective. stops, the rings remain in the positions determined by the stops but the cover can slide on the rings. It is only when the cover is rotated clockwise that the cover is stopped and prevented from further movement. Of course the stops and the helical portions can be reversed so that it is nec sary to rotate the cover in the other directions to effect the locking of the cover. 7
It will be appreciated that the invention has outstanding merit for the intended purpose even in the absence of the provision of means for locking the cover, especially when the container is to be filled with solid rather than liquid material and the provision of a tight seal is unnecessary. It is contemplated, therefore, that for some uses the cam surfaces 29 and the horizontal surfaces 36 may be omitted, together with the provision of means for positively driving the ring 13 into the locked position.
The construc'tionoi the container and the cover is such that they can be readily assembled by automatic machinery. The dimensions and shape of the lugs 49 are such that it is impossible for them to enter either of the grooves 21 or 22 in the container. The only groove that .the lugs can enter is groove Q23. Consequently, rotation otthe 'coveris prevented until the detents 39 and 38 are positions to enter their grooves 2 1.and 22, respectively.
From the foregoing it will be seen that this invention provides a novel combination lock for a container cover which is easily opened and closed and locked by one able to read and understand directions, but cannot be opened by small children, nor by adults unless the directions are followed exactly. Thus even an adult cannot open such a container accidentally.
The scope of the invention is indicated in the appended claims.
