PATENTEU JUL 1 0 ma SHEET 3 OF 3 .l/ I I l// 0 2 w u a w F'IEQ I INVESTOR, RAYMOND FRANK FISCHERIJR TAMPERPROOF CONTAINER FOR VIALS OR THE LIKE This invention relates to special receptacles and packages and, more particularly, to pilferproof containers.
BACKGROUND OF THE INVENTION Pilfering and tampering with goods have long been a problem in commerce in general and, particularly, in the conduct of medical services. Extensive efforts have been made to develop tamperproof containers to hold vials of medicinal products and'small items which are i normally prey to theft so that these items cannot be taken without the knowledge of appropriate authorities.
To be effective, a tamperproof container should be constructed so that items cannot be removed from the container without having the container indicate the exact number of times the container had been opened and the quantity of items which had been removed. For example, previous attempts to develop tamperproof containers provided sealed, single compartment containers to hold a plurality of items. These containers had to be ruptured, or altered in some other way, to remove one single item. However, after the container was altered or ruptured to obtain the first of the several items therein, it would be possible to easily remove the remaining contents of the container without anyone knowing exactly how many were taken or by whom. An example of such a device is the US. Patent to E. J. Meierhoefer, No. 3,494,458, which is used to hold a plurality of syringes. Once the container is opened, access can be had to the syringes remaining in the container.
Tamperproof containers should also be constructed- ,so that the contents of a partially opened container tents through openings which have been made previously in the container.
SUMMARY 'OF THE INVENTION To overcome the problems set forth in the prior art,
the present invention sets forth a tamperproof container, having a receptacle base and a lid which are adapted to be permanently fixed to each other by means pf interfitting columns and pins projecting from the lid and receptacle base. The interfitting columns andpins separate the assembled container into a plurality of sections which hold the items to be dispensed. Frangible zones formed in the lid of the container are aligned with each of the sections formed within the container. The items kept in each of the sections of the containercan only be removed by removing the frangible zone in alignment with the particular section in which those items are kept. The construction of the interfitting structure can be varied to make the lid and base suitable for fastening means by mechanical joining, chemical bonding, or ultrasonic welding.
Accordingly, it is an object of the present invention to provide the components of a tamperproof container which container is constructed so that it must be deformed each time access is gained to a separate section of the container.
Another object of the present invention is to provide the components of a tamperproof container which container cannot be temporarily deformed to allow surreptitious removal of items from the container.
It is a further object of the present invention to pro. vide the components of a rugged and durably constructed tamperproof container, which components include structural members to fasten together the components of the container and, at the same time, to separate the container into separate sections.
Yet another object of the present invention is to provide the components of a tamperproof container which components include simplified interfitting means to permanently join the lid and the base of the container.
Another object of the present invention is to provide the components of a tamperproof container which components are relatively inexpensive to fabricate.
It is still another object of the present invention to provide the components of a tamperproof container,
which container, when assembled, has several sections,
and access to each section can be obtained only by deforming a portion of the container directly proximate to that individual section of the container.
A further object of the present invention is to provide the components of a tamperproof container which components are relatively easy to fabricate and assemble. i v
These and other objects and advantages of the invention will be apparent from the following detailed description taken in conjunction with the drawings illustrating a preferred embodiment of the invention.
DESCRIPTION OF THE DRAWINGS bers shown in FIGS. 4 and 5, which connect the lid of the container to the base of the container.
FIG. 7 is a sectioned view, similar to FIG. 4, showing another embodiment of the invention.
FIG; 8 is a sectioned view, similar to FIG. 5, of the embodiment of the invention shown in FIG. 7.
FIG. 9 is an enlarged section of the interfitting members shown in FIGS. 7 and 8, which connect the lid of V the container'to the base of the container.
DESCRIPTION OF THE PREFERRED EMBODIMENT I FIG. 1 shows a tamperproof container, generally indicated at 10, having a receptacle base portion 12 and a lid portion 14 which container holds .a plurality of vials 16. A pocket 18 formed on front wall 20 of the base can be used to hold either a sign-out sheet for items taken from the container or literature regarding items which are kept in the container.
As seen in FIGS. 2 and 3, lid portion 14 and base portion 12 are designed to be fabricated in single molding operations from many of the widely used commercial plastics. The container base 12 is separated into a plurality of sections by several hollow columns 32 extending upwardly from the floor 34 of the base. The lid 14 is formed with a lateral rib 22 and a plurality of front and rear ribs 24 and 26 respectively which intersect the lateral rib. A plurality of breakaway tabs 28 are connected to the lateral and front and rear ribs by means of relatively thin ligaments 30 of the fabricating material, to form frangible zones in the lid.
As shown in FIGS. 4, and 6 of the drawings, the lid of the container is connected to the base by means of interfitting projections which extend from the container base and the lid. connecting pins generally indicated at 48 are formed at the intersections of the lateral rib with the front and rear ribs of the lid and extend downward into the container to interfit with the columns 32 extending upward from the base container.
The-interfitting pins and columns separate the volume'of the assembled container into several sections, each' of which could securely hold an appropriately shaped object such as a cylindrical vial, having a diameter large enough to prevent passage of the vial between adjacent columns 32 or the columns and the adjacent walls of the base. To facilitate holding smaller objects, each separate section of the base is partitioned off into a receptacle 46 by a series of webs. As shown in FIG. 3, lateral webs 36 connect the upright hollow columns with the left and right side walls of the base 38 and 40 respectively and with the other hollow columns. Front and rear webs 42 and 44 respectively connect the hollow columns to frontwall and the rear wall 45 of the container base. i
As seen in FIG. 6, each connecting pin 48 comprises vone or more fingers 50 which coact with the corresponding hollow column and with each other to mechanically join or interlock the pins to the columns.
Each finger has an engagement protrusion'in the form of a tapered nib 54 with a shoulder 56 on the upper surface of each nib. The fingers in each connecting pin are radially spaced about a central axis 52 of the pin with the nibs facing outward. The end portion 60 of each 7 finger is narrowed by shoulders 62 in the sides of the fingers to insure that there is enough spacing between the nibs to allow sufficient movement of the nibs when they engage the corresponding hollow column as explained below.
In order to interlock connecting pins 48 with the corresponding hollow columns 32, the tapered nibs 54 on the fingers 48 are forceddownward into hollow column 32 until the shoulders 56 of the nibs pass through the aperture of the annular flange 58 at the top of the column. As the tapered nibs are forced downward through the'aperture, the walls of the flange coact with the nibs to press the nibs radially inward and, therefore, resil- -'iently bend the fingers .intoa relatively compact position. After the shoulders of the nibs have passed through the paerture of the flange the natural resilience of the material from which the fingers are fabricated will cause the nibs to move radially outward, thereby engaging the shoulders 56 of the nibs against the underside of the annular flange. It will then be impossible to remove the connecting pin from the hollow column without breaking the annular flange 58 of column 32 or the nib 54 of the finger 50.
The structure of the container lid coacts with the structure of the container base to provide an absolutely tamperproof container. As shown in FIG. 2, each of the breakaway tabs effectively covers the space between the adjacent ribs of the lid structure. As can be seen from FIGS. 2 and 4, the ribs on the lid intersect at positions which coincide with the location of the upright hollow columns 32 of the base so that the breakaway tabs of the lid are in alignment with each section formed by the connecting pins and hollow columns, as previously mentioned. Further, as shown in FIGS. 4 and 5, each breakaway tab 28 has a vertical skirt section 64 which extends sufficiently close to the base of the container to prevent the removal of items from the container base by extracting them from the space between the lid and the base. Because of the relative thinness of the ligaments 30 holding the breakaway tabs to the ribs in comparison to the size of the ribs, it is impossible to bend or substantially deform the rib structure of the lid to raise the lid without fracturing the ligaments and thereby permanently removing one of the breakaway tabs. Therefore, the only way to obtain access to each section formed within the container is to remove the breakaway tabdirectly above that section to which access is desired by breaking the ligaments connecting the breakaway tab to the rib structure of the lid. I As shown in FIG. 5, the front and rear ribs 24 and 26 of the lid and the breakaway tabs attached to each rib extend beyond the front and rear walls 20 and 45 of the container base. Also, the vertical skirts 64 of each breakaway tab 28 are raised above the walls of the container base. Therefore, the bottom ends of breakaway tabs 28 are readily availableto be pushed or lifted by a finger or any convenient pry, so that easy removal of each tab is assured. I
If desired, the position of the columns and pins can be reversed, so that the pins extend from the container base and the columns extend from the-lid. Also, it is not essential that the columns be completely hollow, as illustrated. Further, the orientation of the nibs and the flange in FIGS. 1 through 6 may be reversed. The flange in the column need not have an aperture but, instead, could extend beyond the width of the column to coact with inwardly facing finger nibs, to force the fingers apart during installation and prior to engagement of the shoulders with the flange.
Another embodiment of the invention is shown in FIGS. 7 through 9, in which the lid of the container is adapted to be fastened to the base either by chemical bonding or ultrasonic welding. Those elements appearing both in FIGS. 1 through 6 and FIGS. 7 through 9 are identified by the same reference numbers.
As shown in FIG. 9, connecting pins 70, extending from lid 14, are cylindrically shaped tubular projections having inner surfaces 72 and outer surfaces 74 with tapered outer end portions 76, which are adapted to coact with the upper ends of the hollow columns 32, generally indicated at 78. An inner tapered section in the upper end 78 of each hollow column 32 corresponds with and is adapted to receive and mate with the tapered section 76 of the connecting pins 70. A step 82 connects inner tapered section 80 to the inner wall 33 of hollow columns 32.
A small shoulder 84 on the tapered section 76 of connecting pin 70 is adapted to abut with a flat end section 86 at the end of hollow column 32 to position the connecting pin with respect to the hollow column. Additionally, the end surfaces 23 of lateral rib 22 are adapted to contact the upper surfaces 29 and 41 (see FIG. 3) of side walls 28 and 40 respectively. Further, bottom surfaces 25 and 27 of front rib 24 and rear rib 26 respectively are adapted to contact the top surfaces 21 and 47 of the front and rear walls and 45 of the container base.
The abutting surfaces just described are fastened to each other either by chemical bonding or by means of ultrasonic welding. When chemical bonding is used to fasten the lid to the base, a bonding agent is applied to the mating surfaces to be bonded, as dictated by standard bonding procedure. When ultrasonic welding is used for fastening the components of the device, the components are assembled and a commercially available ultrasonic welding horn is connected to the lid 14 or the base 12. The energy from the welding horn in the form of ultrasonic vibrations is transmitted to all the abutting surfaces of the lid and the base. The heat produced by the ultrasonic vibrations quickly fuses the abutting surfaces to form a rigidly fastened structure which cannot be disassembled.
If desired, the connecting pin 70 may be made as a solid, bullet-shaped member instead of a hollow member, as illustrated. Also, the tapers may be reversed so that the connecting pin itself has a recessed socket-type tapered top, while the hollow column ends in a conical projecting taper.
Although the containers described show only two rows of separate sections holding five vials each, the container structure is suitable for expansion to any number of rows of any quantity.
The container is relatively easy to fabricate in any of the convenient mass production commercial plastics. The containers in accordance with the invention are made clear or opaque. They can be made in varying sizes and can be made to have individual sections of varying sizes to hold a wide variety of vials or other items.
