Lipari [57] ABSTRACT A tamper-proof container, such as the modular companmental type for holding pencil-type articles such as hypodermic syringes, pencils, pens, etc. The container is formed of first and second similarly molded units having guide means and fastening means thereon for permanently orienting and locking the units together. Atab must be fractured for removal of any one article from the container, the remaining succeeding articles in the container being precluded from removal due to the construction of projecting members therein.

10 Claims, SDrawing figures FATENTED APR 1 71973 SHEET 1 OF 2 TAMPER-PROOF CONTAINER BACKGROUND or THE INVENTION This invention relates to tamper proof containers for holding articles and, in particular, to tamper-proof containers of the modular compartmental snap together type for holding pencil-type articles, such as hypodermic syringes, pencils, pens, etc.

At times, it is most important for security reasons or otherwise to prevent theft and maintain an accounting of certain packaged articles, such as hypodermic syringes. Heretofore, such containers have either been costly-to manufacture, difficult to permanently assemble or deficient in providing non-access to remaining articles in a container once some of the articles have been removed therefrom.

SUMMARY or THE INVENTION It is an object of this invention, therefore, to obviate the above-mentioned difficulties and to provide a container which is tamper-proof, simple to permanently assemble and relatively inexpensive to manufacture.

The container includes first and second similarly constructed units including, a first pair of opposing walls each having guide means and guide receiving means thereon, and a second pair of opposing walls, one of which is provided with a plurality of successively arranged tabs thereon. A projecting member extends between each tab and forms a pocket therewith at one end of the unit for receiving one end of an article, and receiving means are located near the other end of the unit for receiving the other end of the article. Fastening means are provided on each unit, the fastening means of one unit being cooperatively associated with the fastening means of the other unit, said units forming a compartmental container when one unit is inverted in face to face relationship with the other unit and urged together whereupon the guide means on one unit is inserted into the guide receiving means of the other unit and the fastening means of one unit is positively locked with the fastening means of the ;other unit, thereby preventing the separation of one :unit from the other unit and precluding the removal of any article from the container except upon the fracturing of a tab.

BRIEF DESCRIPTION OF DRAWING Other objects and a fuller understanding of the invcntion may be had by referring to the drawings in which:

FIG. 1 is an isometric view of one of the units; FIG. 2 is a plan view of one of the units; FIG. 3 is a view taken along the lines 3-3 of FIG. 2; FIG. 4 is a view taken along the lines 4-4 of FIG. 2; and

FIG. 5 is a view taken along the lines 5-5 of FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawing,there is depicted a molded compartmental unit, generally referred to at 10, which is of a plastic material possessing slight resilient properties, such as polystyrene. A second molded compartmental unit, generally referred to at is identical in construction, function and result as unit 10 and, therefore, the description of one will suffice for the description of the other. For the sake of simplicity, however, like reference numerals on unit 10 will be followed by the prime designation. It shall be seen that when one of the units is inverted and positioned face to face with the other, the units snap together to form a tamper-proof container, now to be described in detail.

Unit 10 is provided with a pair of opposing side walls 11-11 disposed in parallel relationship. Located on each side wall is a guide 12-12 which projects upwardly from the base of the unit and converges slightly inwardly near the top end thereof. Also located on each side wall are a pair of guides 13a-13a and 13b-13b, respectively, which project upwardly from the base of the unit to form respective receiving slots 130-130 therebetween, the inner opposing top portions of the guides preferably being tapered to facilitate the reception of tabs 12'-12" of unit 10, to be described hereinafter.

Projecting from the base of unit 10 are a plurality of elements 15-15, preferably connected to projecting members 27-27 to facilitate stability thereto. Each of the elements 15-15 are provided with top portions so shaped to form hooks 150-150, that is surface 15b of each top portion extends angularly downwardly and abruptly inwardly, as surface 150-150, to form an angle, preferably between 60 and with one side of the element. Also projecting from the base of unit 10 are a plurality of resilient elements 16-16 which are in parallel relationship to each other and to elements 15- 15. The top portions 16a-16a of resilient elements 16-16 are identical to elements 15-15, that is, surface 16b of each top portion extends angularly downwardly and abruptly inwardly, as surface 160- 160, to form an angle, preferably between 60 and 85 with one side of the element. Further, located on each resilient element 16-16, are a pair of laterally extending blinders 16d-16d which prevent lateral disengagement of hooks 16a-l6a with books 15a'15a', and vice versa when the aforesaid hooks are locked together in a manner now to be described.

It will now become apparent, as seen in FIG. 3, that when one unit, e.g. unit 10 is inverted with respect to unit 10', guides 12-12 of unit 10 are in alignment with respective receiving slots l30'-l30 of unit 10' and guides 12'-l2 of unit 10' are aligned with respective receiving slots -130 of unit 10. In turn, hooks 15a'-15a' of unit 10 are oriented with hooks 16a- 16a of unit 10 and hooks 1Sa-15a of unit 10 are oriented with hooks 16a'-16a' of unit 10. As the units are pressed together, guides 12-12 and 12'-12' will pass through respective receiving slots 130'-l3c and 130-130 and in turn, relative sliding movement results between the angularly downward surfaces 15b- 15b of elements 15 with the angularly downward surfaces l6b'-16b' of element 16, and between the angularly downward surfaces 15b'-l5b of element 15' with the angularly downward surfaces l6b-l6b of element 16. During said relative sliding movement, the hooks temporarily bend until hook surfaces '-150' snap into engagement with hook surfaces -160, and hook surfaces 15c-l50 snap into engagement with hook surfaces 160l6c' thereby causing the hooks to snap back to their normal vertical positions and, in

turn, causing the unit to permanently lock together. It

alsois apparent that blinders 16d16d and l6d'16d will prevent any lateral disengagement with their hooks 15a-15a' and 1Sa-15a, respectively. As a result of the foregoing, units 10, 10' are oriented and permanently, locked to each other, all of the guides and blinders preventing any lateral or horizontal movement of the units, and all of the hooks precluding any vertical movement of the units.

Located at one end of unit 10 is a wall 20 whose top surface is provided with a succession of arcuately shaped recesses 2l--21, each recess being contiguously connected to each other by a flat surface 2222. Located at the other end of the unit is a wall, generally referred to at 25, which includes a plurality of successive tabs 2626, each tab being separated from the other by a projecting member 27--27. The tabs 2626 are so disposed that each is in alignment with a respective recess 21, and each projecting member 27 is in alignment with a respective flat surface 22. Accordingly, pockets 3030 are respectively formed as a result of the arrangement of the projecting members 2727 with each of the tabs 2626, each pocket being capable of receivingone end of an article 41 to be inserted therein, as described hereinafter.

Located on the base of unit 10 near wall 20 are a plurality of split-tapered sleeves 35-35, the sleeves tapering downwardly towards wall 20 for receiving the other end of the article to be inserted therein. Each sleeve is disposed between and in alignment with a respective tab 26 and a recess 21.

In operation, as seen in FIGS. 2 and 5, one end 40 of article 41, such as a hypodermic syringe, is inserted into split-sleeve 35, and the other end 42 is then moved downwardly into pocket 30. The arrangement and structure of the compartmental components, as seen in FIG. 5, are such that each end of the article is snugly received in split sleeve 35 and pocket 30, respectively. Each of the pockets and split-sleeves of unit 10 and 10' are similarly filled.

As previously described, one unit is inverted with respect to the other such that guides 12'l2' of unit 10 are located within receiving slots 130-130 of unit 10 and, similarly, guides 12--12 of unit 10 are located within receiving slots l3c'c. As the two units are pressed together, the guides are inserted into their respective slots, and hooks la--15a of unit are snapped into a locking position with hooks 16a'-16a of unit 10 to positively lock the units together and vice versa. As a result, as seen in FIG. 4, flat surfaces 22- 22 of unit 10' are in contact with the top surface of respective projecting members 2727 of unit 10, and recesses 21'2l are located over the top surface of respective tabs 2626 thereby forming respective openings 4545 therebetween. Similarly on the other end of the unit, flat surfaces 2222 of unit 10 are in contact with the top surface of respective projecting members 27'-27' of unit 10', and recesses 21-2l are located over the top surface of respective tabs 26'--26 thereby forming respective openings 4545' therebetween. As seen in FIG. 5, therefore, the articles in one unit are disposed in opposing relationship to the articles in the other.

As a result of the units being locked in this position, there can be no removal of any of the articles unless a tab 26 is fractured. Thus, in the event one desires to remove an article from its compartment, one inserts his finger or an implement into opening 45-45 or 45 45 and pulls the tab outwardly from the unit in a downwardly direction until the tab fractures, said fracture generally occurring in the area referred to as 46. Upon removal of the fractured tab, the end 42 of article 41 is grasped and withdrawn from the unit. It should be noted that when one article or any Succeeding articles are removed, no access is provided to the remaining articles in view of projecting members 2727 shielding same. The only way any individual article can be withdrawn is by fracturing the tab associated therewith. Accordingly, one may always have knowledge of the number of articles removed from the units by merely visually observing the number of tabs which have been fractured.

It should be understood that while a preferred embodiment has been described, numerous modifications can be made without departing from the spirit and scope of the invention. For example, while arcuately shaped recesses 21-21 have been provided on wall 20 for permitting access to the tabs 26-26, wall 20 can be linear and the top surfaces of the tabs provided with recesses.
