Abstract A tamper-proof container, such as the modular compartmental 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. A tab 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.

Claim 1
Independent Claim
217 words
A tamper-proof container for holding articles, which comprises, first and second similarly constructed units, each of said units including: a first pair of opposing walls each having guide means and guide receiving means thereon, a second pair of opposing walls, one of which is provided with a plurality of successively arranged tabs thereon, a projecting member extending between each tab and forming a pocket therewith at one end of the unit for receiving one end of an article, receiving means located near the other end of the unit, each receiving means being oriented with each formed pocket for receiving the other end of the article, and fastening means connected to each unit, the fastening means of one unit being cooperatively associated with the fastening means of the other unit, said units forming a closed tamperproof compartmental container when one unit is inverted in face to face relationship with the other unit and urged together, the guide means of one unit being inserted into the guide receiving means of the other unit and the fastening means of one unit being 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.

Claim 5
Dependent Claim
50 words
A container, according to claim 2, wherein the projecting member extends upwardly substantially to the height of the unit and extends inwardly towards the other end of the unit a sufficient distance to positively shield and insure lateral non-access to a succeeding article upon the fracturing of a preceding tab.
Claim 6
Dependent Claim
37 words
A container, according to claim 2, wherein the receiving means located near said other end of the unit is an open ended split-sleeve element whose article entrance end is of a larger diameter than its exit end.
Claim 7
Dependent Claim

A container, according to claim 2, wherein at least one of the fastening means of each unit is provided with a pair of laterally extending blinders for preventing any lateral disengagement of said fastening means when it is locked with the fastening means of the other unit.
Claim 8
Dependent Claim
66 words
A container, according to claim 6, wherein the fastening means includes a top portion which extends angularly downward and abruptly inward, there being relative sliding movement between the fastening means top portion of one unit with the fastening means top portion of the other unit as the said units are being urged together, said top portions locking together as the abruptly inward surfaces contact each other.
Claim 9
Dependent Claim
44 words
A container, according to claim 7, wherein the fastening means of each unit temporarily bends during the relative sliding movement of the respective top portions of the units, said top portions returning to their normal positions as their respective abruptly inward surfaces snap together.
Claim 10
Dependent Claim
30 words
A container, according to claim 8, wherein the angle formed by the angular downward surface with the abruptly inward surface of said top portion preferably is between 60* and 85*.
Claim 11
Dependent Claim
114 words
A container, according to claim 9, wherein the second pair of opposing walls is provided with a succession of concave surfaces, each concave surface providing an access opening for its respective tab when the closed compartmental container is formed, said projecting member extends upwardly substantially to the height of the unit and extends inwardly towards the other end of the unit a sufficient distance to positively shield and insure lateral non-access to a succeeding article upon the fracturing of a preceding tab, and said receiving means located near the said other end of the unit is an open ended split-sleeve element whose article entrance end is of a larger diameter than its exit end.
