Definitions
- ABSTRACT OF THE DISCLOSURE A container and replaceable safety closure therefor wherein the container and closure have portions that are yieldable to interengage when the closure is snapped over the container mouth and wherein the outer diameter of the closure is not greater than the portion of the container on which it rests so as to render it extremely difficult to pry off of the mounted closure and a flush fitted flap integral with the closure that may be swung from its flush position on the closure to an open grasping position by the user to facilitate forcible removal of the closure from said container, the dimensions of the closure and the normally flush position of said flap making it difficult for children to remove the closure from the container, thus providing safe storage for dangerous container contents.
- This invention relates to a safety container and closure therefor of relatively simple construction that is inexpensive to produce on a mass production basis and fully effective for its intended purposes, making it difficult for children to gain access to dangerous contents but yet permit simple manipulation for authorized removal of such contents.

- FIGURE 5 is a sectional view taken along line 55 of FIGURE 4;
- FIGURE 6 is a sectional view taken along line 6-6 of FIGURE 5;
- FIGURE 7 is a sectional view similar to FIGURE 5 illustrating parts of the cap in the condition for removal of the latter;
- FIGURE 8 is a sectional view of the cap and container mouth in separated condition
- FIGURE 9 is a perspective view of the removal cap
- FIGURE 10 is a plan view of a modified type of safety cap construction
- FIGURE 11 is a fragmentary sectional view taken along'line 1111 of FIGURE 10.
- FIGURE 12 is a fragmentary sectional view of a modified type of container on which the safety cap of this invention is mounted.
- the reference character 10 denotes a container or receptacle of any suitable material although preferably a moldable synthetic material such as polyethylene, polypropylene, copolymers of these materials or other moldable plastic having the characteristics of a solid ethylene polymer.
- this container 10 has substantially cylindrical shape and walls of substantially uniform thickness except in the open mouth region whereat an upwardly tapering annular external shoulder 11 is provided somewhat below the upper edge 12 of the container to define a substantially flat horizontal upper ledge 13.
- the wall 14 of shoulder 11 below its ledge is tapered to merge with the main outer surface of the container.
- a recessed portion 15 is provided in the container wall which is joined by an annular tapered wall 16 to a thickened peripheral engageable portion or lip 17 at the upper end of the container 10. If the container 10 is of moldable material, these components may readily all be formed at its upper end during the molding process.
- a safety cap 18 preferably of the same molded synthetic material or material as is mentioned in detail below is provided for mounting as a closure over the mouth of container 10.
- the side wall 19 of this cap 18 is provided with a finished bottom edge 20 intended to seat closely on the upper surface of ledge 13 with a minimal discernable juncture at the abutting surfaces.
- the diameter of this cap is not greater than the outer diameter of the ledge 13.
- the inner surface of the side wall 19 of cap 18 substantially is complemental, in sectional shape to the shape defined by the annular groove 15 and by lip 17 of the container.
- This side wall 19 is sufiiciently yieldable to permit the cap 18 to be snapped into closing condition on the container and to be retained snugly therein by interengagement of the mating parts of the container 10 and cap 18.
- cap 18 At this time, the smoothly finished abutting ledge 13 and edge 20 of cap 18 are maintained with a close fit and since the diameter of cap 18 is not greater than ledge 13, the insertion of a fingernail, knife blade or other prying device to separate the cap and container is prevented. This prevents or makes very diflicult the opening of the container by children or accidentally by others.
- This removal means comprises a flap or tab 22 integral with the said top wall 21 which normally fits closely within a shallow recess 23 provided in a central portion of said top wall.
- This recess 23 has a central substantially rectilinearly shaped recessed portion 24 of substantially greater depth provided with a flat bottom wall 25
- Whose opposite longer vertical side walls 26 preferably are grooved longitudinally at 27 for purposes presently to be described.
- One end wall 28 is substantially vertical and the other end wall 29 tapers upwardly and both join the horizontal bottom flat 30 of the shallow recess 23.
- This recess has opposite side walls 31 that taper towards each other, being joined by a curved end wall 32 and an oppositely located substantially straight end wall 33.
- the flap 22 is jointed integrally to the cap at the region adjacent end wall 33 and has an overall contour complemental in shape to the recess 23 being provided also on its under face with a projecting island 34 whose contour is complemental to the contour of deeper recessed portion 24 and into which said island is designed to be received with a snug fit.
- the longitudinal side walls of island 34 are provided also optionally with ribs 35 that are ladmeasured to fit snugly into grooves 27 in side walls 26 of recess 24.
- the unattached forward end 36 of flap 22 is complemental in shape to curved wall 32 of recess 23 and provided with a think flexible lip 36 which is slightly spaced from wall 32 to permit insertion of a fingernail or other prying means to swing the flap 22 out of its nested retained position in recesses 23 and 24 about its hinged joint with cap 18 at wall 33.
- the bottom face of island 34 is preferably serrated at 37 so that in nested condition of flap 22, the extremities of its serrations rest on the bottom face of recess 24 to provide a firm support for the nested flap 22 whose upper face then lies substantially flush with the top surface of cap 18 to facilitate imprinting of suitable indicia onto the top SLlI'fHJC6S of the cap and flap.
- the serrations 37 provide gripping surfaces for the users fingers to facilitate removal of the cap 18 from container 1th
- the fiap 22a is provided along its end 36 with an integral projecting frangible tab 38 that in nested condition of said flap 22a fits into a complemental recess 39 in the top of cap 18a and into which it may be secured by appropriate adhesive.
- a score line 40 is provided at the juncture of tab 38 and flap 22a to facilitate separation of the two when it is desired to swing flap 22a into cap-removing position.
- frangible tab 38 adhered to cap 18a in recess 39 thus provides a protective member to prevent accidental dislodgment of flap 22a from its normally nested position prior to application of cap 18a to a container and further as an indicator to the user that prior to first opening of the container the contents of the latter have not been changed or adulterated.
- the caps 18 and 18a are molded preferably by injection molding and the synthetic plastic material thereof which may be polyethylene, polypropylene or copolymers of these materials which in the wall thickness employed are sufiiciently flexible to permit mounting of the cap and also swinging movement of the flap and yet provide sufiicient strength to prevent its tearing when grasped to remove the cap.
- caps 18 and 18a have been shown in FIGS. 1-11 as applicable to cylindrical containers 10, they are likewise applicable to containers of different shapes, for example, the containers 10a of FIGURE 12 wherein the diameter of its opening is actually smaller than that of the main body of the container.
- the container wall 41 defining the opening is provided with an external recess 42 directly below its lip 43 which is admeasured to receive the complementally shaped portions of the cap 18 or 18a when the latter is snapped into place.
- the height of wall 41 is admeasured so that when so mounted the bottom edge wall of cap 18 or 18a then snugly abuts the fiat outer wall portion 45 of container 10a lying fiush therewith and being of smaller diameter than the wall portion 45 thus precludes insertion of a users fingernail or other prying tool therebetween, thus preventing removal of the applied cap from the contained by such operations.
- caps 18 or 18a with their flaps in nested condition are snapped over their open mouths. Thereafter, the caps can only be removed by prying the flaps 18 or 18a into unfolded condition by a fingernail or other prying means and grasping the flap to pull the cap ofi" the container. To reclose the containers, its flap is again nested and the cap snapped back over the container mouth. This may be repeated indefinitely as required to remove selected amounts of container contents.
- a container and safety closure means therefor said container having a mouth, an engageable portion at said mouth, a recessed portion adjacent said first-named portion and a laterally projecting portion below the recessed portion
- said safety closure means comprising a one-piece snap-on cap having a side wall whose inner portion has a surface complemental to that of said first and secondnamed portions and an abutment wall adapted to rest on said laterally projecting portion in such disposition as to prevent prying the mounted cap off said container, a flap portion integral with said cap, and at least one recess in said cap for receiving and retaining said flap in flush disposition relative to the top surface of said cap, said flap being swingable from said flush disposition to an open grasping position to facilitate forcible removal of the entire cap from said container.
- a container and safety closure therefor according to claim 1, wherein two recesses are provided in said cap, one of said recesses being deeper than the other and wherein said flap has an island portion fittable into said one of said recesses when said flap is in flush dis position with respect to the top surface of said cap.
- a container and safety closure therefor said container having a mouth, an engageable portion at said mouth, a recessed portion adjacent said first-named portion and a laterally projecting portion below the recessed portion
- said safety closure means comprising a one-piece snap-on cap having a side wall whose inner portion has a surface complemental to that of said first and secondnamed portions and an abutment wall adapted to rest on said laterally projecting portion in such disposition as to prevent prying the mounted cap off said container, at flap portion integral with said cap, and at least one recess in said cap for receiving and retaining said fiap in flush disposition relative to the top surface of said cap, said flap being swingable from said flush disposition to an open grasping position to facilitate forcible removal of the entire cap from said container and including frangible means for securing said flap in said flush disposition in said cap.
- a safety closure cap for application to a container according to claim 2, wherein said one of said recesses and said island portion have interengageable ribs and grooves for retaining said flap in its said flush disposition.
