Description

Nov. 17', 1964 A. S. HAKIM CONTAINER Filed March 3, 1964 m M m w m M w 5 United States Patent 3,157,302 CUNTAINER Albert S. Hakim, York, 326 De Siard, Monroe, La. Filed Mar. 3, 1964, Ser. No. 349,008 Claims. (Cl. 215-9) This invention relates to containers generally, and more specifically, to a safety container for storage of potentially harmful substances such as certain medicines, poisons, and the like.

A primary object of this invention resides in the provision of a safety container involving a receptacle and a closure means therefor, there being dual locking means to positively prevent access to the contents of the receptacle by children or by other persons not competent to handle materials of the type indicated above. ous devices relating to the general concept of supplying a medicine container and, a closure means not readily operated by children have been previously proposed. However, such previously proposed devices have failed to find general acceptance. It is "therefore an object of the present invention to provide a device of the character indicated which is effective for the purpose of positively preventing access to the contents of a receptacle by unauthorized persons, and which is susceptible of manufacture at a cost competitive with conventional containers for such substances.

Another object of the invention relates to the provision of a dual lock means for a container closure, or the like.

The general objects and advantages of the invention include the provision of a container and closure means therefor which is relatively inexpensive to manufacture and sell and durable in use. Other and further objects and advantages of the present invention will become apparent to those skilled in the art from a consideration of the following specification when read in conjunction with the annexed drawing, in which:

FIGURE 1 is a disassembled perspective view of a container and closure means therefor constructed and assembled in accordance with the teachings of this invention;

FIGURE 2 is a view similar to FIGURE 1, showing the closure means in place;

FIGURE 3 is a top plan view thereof;

FIGURE 4 is a vertical cross sectional view, taken substantially along the section line 4-4 of FIGURE 2, looking in the direction of the arrows;

FIGURE 5 is a top view similar to FIGURE 3, showing the elements in position for disassembly; and

FIGURE 6 is a sectional view along the line 6-6 of FIGURE 5, looking in the direction of the arrows.

Referring to the drawing in more detail, the container of this invention is generally designated by reference character 10, and has, as its major components, a cuplike receptacle 12 and closure 14.

The receptacle 12, in the illustrated embodiment, includes a base 16 from which extends a tubular side wall 18 having an inner surface 20 and outer surface 22. The wall 18 includes an enlarged upper end portion 24 termin-ating in an end edge 26. As will be apparent from the description of function below, the configuration of the re cep'tacle below the upper end portion 24 may be varied as desired. In the disclosed embodiment, the upper end portion 24 is connected to the wall 18 by a shoulder 25, and is of reduced thickness. This provides an interior ledge or shoulder 27, the purpose of which appears below.

At spaced locations about the interior periphery of the end edge 26, a plurality of lugs extend inwardly from the inner surface of the portion 24. The lugs are preferably of various, mutually distinct forms and configurations, such as the three illustrated lugs involving a gen- Numer- Patented Nov. 17, 1964 erally triangular lug member 28, a narrow rectangular block lug 30, and a wide rectangular block lug 32. The lugs include lower sides 34 occupying, preferably, a common horizontal plane.

The inner surface of the wall 18 adjacent the shoulder 25 has screw thread means 36 formed therein. Thus, a smooth inner wall section 38 is provided on the portion 24.

The closure 14 comprises a body 40 having an enlarged upper end portion 42, adapted to rest on the ledge or shoulder 27, and a depending, reduced portion 44, the body portions being of generally discoidal configuration. The reduced portion 44 has a side edge 46 which is screw threaded for engagement with the thread means 36 of the receptacle 12. As best seen in FIGURE 6, the body 40 is of a diameter, and is of such depth from its upper portion 42 to its lower reduced portion 44, less than the distance between the lug lower sides 34 and the thread means 36, whereby it is freely movable nad rotatable within the smooth wall portion 38. It is preferable however that the outside diameter of the upper portion 42 and the inside diameter of the wall 38 be held to close tolerance, and that the side edge 47 of the upper portion be squared, to prevent relative movement in other than linear fashion.

The body 4t? has an upwardly projecting, substantially centrally located pair of projections 48, defining a slot 52 therebetween, th slot 52 being adapted to receive a small coin, screwdriver, or other small, straight edged instrument for turning the closure, thus rendering it diificult for a child to grasp the same for manual turning of the ciosure. The coin or tool must be of such width as to frictionally engagethe sides of the slot.

The slot is of such form that an adult, by reasonably careful manipulation, is able to engage a coin or the like therein and manually turn the closure when the threaded portion 46 is disengaged from the thread means 36. In emergency situations, when an opening tool is unavailable, the user may grasp the projections 48.

The upper portion 42 of the closure has a plurality of openings formed therein, opening on the side edge 47. Such openings correspond innumber, location, and configuration with the plurality of lugs-as shown herein, comprising a triangular opening 54, a thin rectangular opening 56, and a wide rectangular opening 58the openings corresponding respectively, to the triangular lug 28, the thin trectangular lug 3t and the wide rectangular lug 32.

In initial placement of the closure 14 on the receptacle 12, the corresponding lugs and openings are aligned and the body 40 is dropped into place-a suitable tool being used to cause engagement between the threads 46 and the thread means 36. When opening is desired, it is necessary to (1) select a tool capable of insertion in the slot 48 and frictionally engageable therein, (2) correctly turn the closure in the appropriate direction to disengage the threads and thread means, (3) withdraw the tool and closure manually and bring the respective corresponding lugs and slots into registry, and (4) manually lift the tool and closure upwardly. This sequence of steps is of such difiiculty as to effectively prevent access to the contents of the receptacle of this invention by children, infirm persons, and the like.

Having described and illustrated an embodiment of this invention in detail, it will be understood that this description and illustration is oifered merely by way of example, and that this invention is to be limited in scope only by the appended claims.
