Patent Dec. 16, 1975 SAFETY AND SECURITY CLOSURE BACKGROUND OF THE INVENTION This invention relates to safety closures for receptacles such as cans, tubes, bottles and the like, and in particular it relates to a safety closure ofthe type having a ring rotatably mounted on a receptacle and threadedly engaged with a cap, wherein the cap must be turned relative to the ring to expose the receptacle opening.
Safety closures of the above described type are known, for example as described in US. Pat. No. 3,403,803, in which the ring is snapped over an external bulge on the neck of a bottle and is then seated thereon so as to be freely rotatable on the bottleneck but prevented from moving off of the bottleneck. The ring includes external threads which are engaged by internal threads of a cap such that the cap covers the opening of the bottle. Both the ring and the cap have outer gripping surfaces which are so shapedby corrugations or the like that the ring appears to be a part of the cap. The desired safety or security function is obtained because inexperienced individuals, particularly children, will turn the cap and the ring together on the bottleneck and this will simply turn both of them together freely about the bottleneck but will not effect separation of the screw threaded engagement between the cap and the ring. For such disconnection, it is necessary to hold both the ring and the cap so as to turn them relative to each other.
SUMMARY OF THE INVENTION The purpose of the present invention is to provide an improved safety closure which has the additional feature of serving as a security closure so as to prevent initial opening of the receptacle and also to give a permanent visible indication of such an initial opening.
This purpose is achieved in accordance with the present invention by providing an external sleeve removably connected to the cap, for example by a tear-off connection, said sleeve covering the gripping surface of the ring. The sleeve prevents holding the ring fixed so that one cannot turn the cap relative to the ring. Only after the sleeve has been removed can the ring be grasped and the cap unscrewed from it. Further, the tearing or pulling off of the sleeve is immediately visible so that any unauthorized opening of the receptacle is then clearly visibly indicated.
In a preferred embodiment of the invention, the sleeve is formed as an annular, external member connected to the cap via lands, permitting the sleeve to be torn off from the cap. The sleeve can have one or more slits therein providing a location for one to grasp the sleeve for removal purposes, and advantageously the sleeve is cast in plastic in one piece with the cap. The sleeve may be bent outwards at the slits so as to facilitate engagement and tearing off of the sleeve.
The engagement of the ring with the receptacle will of course vary, depending on the type of receptacle to which the closure is applied. When used on bottles, the inner edge of the annular ring can be constructed so as to snap behind an annular bulge on the external surface of the neck of the bottle. When used in connection with an aerosol can, the inner edge of the ring can simply be snapped into place behind the edge of the upwardly protruding valve plate. Further, the cross-sectional shapes of the ring and cap can be of many different configurations such that the aboved described features of the inventionare present and so that the closure is adaptedv to fit onto receptacles, of many different shapes. For example, the cross-sections canbe selected so that .the sleeve with lie substantially in the axial extension'of the receptacle wall or alternatively the sleeve could extend over both the'ring and the adjacent receptacle wall. f
BRIEF DESCRIPTION OF THE DRAWINGS DETAILED DESCRIPTION OF THE PREFERRED I EMBODIMENTS Referring now to the drawings, like elements are represented by like numerals throughout the several views.
Referring to FIGS. 1 and 2, for simplicity only the upper portion of the receptacle is shown. In this case the receptacle is a can 10 of the aerosol spray type including a dome 12 with a valve plate 13 provided centrally therein. The annular ring 14 is snapped over the valve plate 13 such that the ring 14 is rotatable freely about the access opening including valve plate 13 but is prevented from moving axially off of the receptacle by engagement of the inner edge of the ring 14 with the outwardly protruding upper portion of the valve plate 13. The ring 14 has exterior screw threads which threadedly engage interiorscrew threads on a cap 16. The ring 14 includes an external gripping surface 18, and the cap 16 also includes a gripping surface, namely the exposed exterior portion thereof. In practice, the cap 16 is removed from the ring 14 to expose the opening, in this case the valveplate 13 by unscrewing the cap 16 from the ring 14.
However, in accordance with a main feature of the present invention, a security means is provided for preventing access to the gripping surface 18 so that one cannot grip the surface 18 to effect relative movement between the elements 14 and 16. This security means comprises a sleeve 22 which covers the gripping surface 18 and is secured to the cap 16 by means of lands or ribs 20 (see FIG. 2). In addition, the sleeve 22 is slit, as shown at 25 in FIG. 2 and preferably the ends 26 of the sleeve adjacent the slit are bent outwardly. In practice, the sleeve 22, which covers the gripping surface 18 to thereby prevent unauthorized opening of the receptacle, is torn away from the cap 16 by grasping one of the ends 26 and pulling the sleeve, thereby breaking the lands 20 and exposing the gripping surface 18. After this tearing action has been completed, it cannot be reversed so that there is provided a visible indication that the security means has been removed.
The sleeve 22 can be shaped so as to correspond to a desired receptacle shape. FIG. 1 shows in solid lines an embodiment in which the sleeve is the form of a thin walled elongated ring formed essentially as an axial extension of the peripheral wall of the can. In dotted lines there is shown a different arrangement whereby the sleeve 22 projects outwardly over the peripheral wall of the can.
FIGS. 3 and 4 illustrate the application of the present invention to a bottle 30 having an external bulge 32in the form of an annular ring formed integrally with the neck of the bottle. The ring in this case which is repre sented by the numeral 34 includes an internal annular groove which mates with the bulge 32 permitting free rotatable movement of the ring 34 about the neck of the bottle while preventing axial movement of the ring off of the bottle neck. The ring includes external screw threads which threadedly engage internal screw threads on a cap 36. The ring further includes a gripping surface 38 which in this embodiment is covered by a sleeve 42 which is integrally connected to the cap 36 by means of lands 40 which are similar to the lands 20 of FIG. 2. Referring to FIG. 4, the sleeve 42 includes a slit 45 with outwardly bent ends 46 similar to 25 and 26 of FIG. 2.
In either embodiment the closure may include a single slit or a plurality thereof. Any convenient means may be provided for effecting removal of the sleeve from the cap, but preferably the sleeve is constructed to be torn away as illustrated and described above. Preferably the sleeve is cast in one piece with the cap and is preferably of a plastic material. Obviously numerous arrangements are possible within the spirit and scope of the invention. For example, the sleeve could be formed as a downward extension of the cap.
Although the invention has been described in considerable detail with respect to preferred embodiments thereof, it will be apparent that the invention is capable of numerous modifications and variations apparent to those skilled in the art without departing from the spirit and scope of the invention, as defined in the claims.
