Description
Field of the Invention
This invention relates to a container which may be used for receiving and shipping various products and which has a tamper-evident seal feature.
Background of the Invention
In shipping a variety of products including pharmaceutical products, containers are utilized which are often constructed of a single material, for example paper, plastic or the like, for purposes of recycling. These containers are often in the shape of a drum having a slip-over type cover which telescopes onto an open upper end of the drum. However, these containers may also include boxes or other shaped containers, either with removable lids or with recloseable flaps. Usually, the only tamper-evident feature utilized with this type of container was a tape secured around the container and over the cover, lid or flap for holding the cover, lid or flap on the body portion of the container.
Object and Summary of the Invention
Therefore, it is the object of this invention to provide a container of the type discussed above with an effective, low cost, tamper-evident means therein.
By this invention it has been found that the above object may be accomplished by providing a container suitable for receiving and shipping various products and which includes a hollow body member having a side wall and a bottom wall connected together, and a removable or recloseable cover means in the form of a cover, lid or flap member having a top wall and a side wall positioned on an upper end of the body member so that the side wall of the cover member is superimposed on the side wall of the body member.
The container further includes the improvement of tamper-evident seal means connected between the body member and the cover means for sealing such members together and for evidencing any premature removal of the cover means. Such tamper-evident seal means comprises two sets of superimposed apertures extending through the side walls of the body member and the cover means, a closed sealing wire in the forth of a suitable metal, plastic or the like member extending through the sets of superimposed apertures and around respective inside and outside portions of the side walls of the body member and the cover member between the sets of apertures and being sealed to form a closed loop, and a patch means secured to an inside surface of the body member and covering the apertures in the body member to prevent contaminants from entering the container through the apertures and to strengthen the area of the body member having the apertures therethrough.
Preferably, the patch means includes a portion unsecured to the inside surface of the body member and extending between the apertures to define a guided passageway between the apertures so that the sealing wire may be inserted through one set of the apertures and guided through the passageway and passed out through the other set of the apertures. It is also preferable to construct the body member, the cover means and the patch means of like material, such as plastic, paper or the like.

Detailed Description of Preferred Embodiment of the Invention
Referring now to the drawings, a partial exploded view of a container 10 suitable for receiving various products is illustrated in FIG. 1. This container includes a hollow body member 11 having a side wall 12 and a bottom wall 13 connected together. The container 10 further includes a removable cover member 15 having a top wall 16 and a side wall 17. The removable cover member 15 is adapted to be telescopingly positioned on an open upper end 14 of the body member 11 so that the side walls 17 and 12 are superimposed on each other. The body member 11 and the cover member 15 may be constructed of any suitable material, such as paper, plastic or the like and may be of any suitable size and shape. In the drawings, the body member 11 is shown to be of drum shape and the cover member is of complimentary shape. However, as set forth above, the container may also be in other shapes including a box having a removable lid or recloseable flap.
The container 10, in accordance with this invention, includes a tamper-evident seal means which is shown in its entirety in FIG. 5 and generally referred to by the reference numeral 20. This tamper-evident seal means 20 is connected between the body member 11 and the cover member 15 for sealing the members together and for evidencing any premature removal of the cover member 15. The tamper-evident seal means 20 includes two sets of spaced-apart superimposed apertures 21 and 22 extending respectively through the side walls 12, 17 of the body member 11 and the cover member 15 of the container 10. A closed sealing wire 24 extends through the sets of superimposed apertures 21, 22 and around respective inside and outside portions of the side walls 12, 17 of the body member 11 and the cover member 17 between the sets of apertures 21, 22, as may be seen particularly in FIG. 5, and is sealed by a suitable seal member to form a closed loop. This sealing "wire" may be in the form of a metal wire or it may be in the form of an elongated plastic or the like member. Thus, if the cover member 15 is removed from the body member 11 the seal 15 and/or sealing wire 24 must be broken to evidence tampering with the container
The tamper-evident seal means 20 further includes a patch member 26 secured to an inside surface of the side wall 12 of the body member 11 and is of sufficient size to cover the apertures 21 in the body member 11 to prevent contaminants from entering the interior of the body member 11 of the container through such apertures. This patch member 26 also acts to strengthen the area of the side wall 12 of the body member 11 which includes the apertures 21 and is somewhat weakened by such apertures 21.
Preferably, the patch member 26 includes a portion unsecured to the inside surface of the side wall 12 of the body member 11 and extending between the apertures 21 to define a guided passageway 27 between the apertures 21 so that the sealing wire 24 can be inserted through one set of the apertures 21, 21, guided through the passageway 27 and passed out through the other set of the apertures 21, 22, as may be seen in FIGS. 4 and 5. The patch member 26 is preferably formed of like material, such as paper, plastic or the like, as is the body member 11 and cover member 15 of the container 10 and may be secured by any suitable adhesive or the like which is compatible with these materials.
By this invention, it may be seen that a cost effective, simple, improved tamper-evident seal means 20 is provided between the cover means 15 and the body member 11 of a container 10 which also includes a novel patch member 26 secured on the inside of the container 10 to prevent contaminants from entering the container 10 through the seal means 20 and which provides a reinforcement to the container 10 at the area of the seal means 20 and, preferably, provides a guided passageway 27 for insertion of a sealing wire 24 forming a part of the sealing means 20.
In the drawings and specification, a preferred embodiment of this invention has been illustrated and described, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation.
