Description
Background of the Invention
This invention relates to multiple container systems, and in particular to a container system having a second container removably mounted on a first container, with the first container being provided with means for both temporarily locking the second container to the first, and means for simply mounting the second container on the first without the ability to lock the two containers together.
Cleanliness and safety are constant concerns in any medical environment. As a result, disposable, one-time use products have proliferated to the extent that their proper dissemination and disposal have become major concerns in any medical facility. Typically, disposable products, such as sharps, tissues and gloves, are stored on shelves or in cabinets, and when used, are disposed of in wastebaskets or other portable containers which are strategically placed within a room. Dispensing and disposal of such products in secure containers has, until recently, received little consideration.
In U.S. Pat. No. 4,863,057, which is assigned to the same assignee as the present application, there is disclosed a secure container system which can be mounted on a wall and which is used for both dispensing and disposal of disposable products. In that container system, however, when the first container has been closed and locked in place, the second container is always held in place and cannot be removed without opening of the first container. While in some instances that result is desired, in other instances, it is desired to be able to remove the second container without having to unlock and open the first container.
Summary of the Invention
The invention relates to a secure container system intended to be mounted on the wall in a room within a hospital, clinic, medical office or other medical facility. It is composed of two containers, the second of which is mounted on the first such that the second can be laterally removed from the first when desired. A stop is provided on the first container for selectively preventing removal of the second container if the second container is located in a first mounting position. The stop is positionable in a first orientation to lock the second container in place in the first mounting position and in a second orientation to unlock the second container to permit its removal.
For mounting of the second container on the first, the second container includes opposite flanges extending outwardly from opposite edges of the container. Two pairs of spaced, parallel channels are located on the first container, with each of the channels of each of the pairs of channels being shaped and located to accommodate one of the flanges of the second container. The channels of the first mounting position are located closer to one side of the first container than the channels of the second mounting position so that the stop, when positioned in the first orientation, will lock the second container to the first container only when the second container is located in the first mounting position. It is preferred that the channels of the first and second mounting positions are juxtaposed in brackets extending from the first container.
The first container includes a door oriented generally perpendicular to the mounting location of the second container on the first. The door has an extended portion projecting adjacent the first mounting position, with that extended portion comprising the stop that may selectively prevent or permit removal of the second container from the first mounting position. The door is provided with a lock so that when the door is closed and latched and the second container is located in the first mounting position, the two containers are irremovably secured together.
The door may further include means extending from the extended portion for temporarily holding the second container when mounted in the second mounting position. The means for temporarily holding preferably comprises a pair of spaced detents extending from the bottom of the door and engaging the top of the second container when mounted in the second mounting position so that the container is held in place while dispensing of gloves or other items therefrom, but can be removed against the holding force of the detents when desired and without opening of the door.

Description of an Example Embodying the Best Mode of the Invention
A container system according to the invention is illustrated generally at 10 in the drawing figures. The container system 10 is composed of two containers, a first container 12 and a second container 14. As illustrated and described in greater detail below, the second container 14 is mounted on the bottom of the first container 12 and may be laterally removed from the first container when desired.
The first container 12 may be an outer enclosure for a wall-mounted sharps disposal system, as disclosed and described in U.S. Pat. No. Re, 33,413, reissued Oct. 30, 1990, the patent being a reissue of U.S. Pat. No. 4,715,498, issued Dec. 29, 1987. As set forth in that patent, the container 12 is intended to include a second, inner disposable container 16 which, when filled with discarded sharps and other wastes, may be removed from the container 12 and suitably disposed. The inner container 16 of the present invention may be substantially identical to that of the '413 patent, may be similar to that disclosed in U.S. Pat. No. 4,779,728, or may be any suitable inner container fitting within the first container 12.
The second container 14 has an opening or dispensing slot 18 so that any items contained within the container 14 can be readily dispensed. The container 14 is sized appropriately in the illustrated embodiment of the invention to accommodate a box of disposable gloves (not illustrated) which is installed within the container 14 with its own dispensing slot in alignment with the dispensing slot 18. When the supply of gloves within the box is exhausted, the second container 14 is removed from the first container 12, the empty box is discarded, and a new box is substituted in its place. It should be evident that the container 14 may be used for selective distribution of any of a myriad of other items, such as tissues, as well.
The second container 14 includes a pair of opposite flanges 20 extending outwardly from opposite edges of one side (the bottom 28) of the container 14. Each of the flanges 20 is shown engaged within a lower channel 22 of a bracket 24, which also has an upper channel 26. The brackets 24 are mirror images of one another, and the upper channels 26, as a pair, comprise a first mounting position for the second container 14, while the lower channels 22 comprise a second mounting position for the container 14. Each bracket 24 may be an integral portion of the container 12 or each of the brackets 24 may be adhesively or otherwise secured to the bottom 28 of the container 12 by any suitable means.
The container 12 has a front door 30 which is mounted on the container 12 by a pair of hinges 32. When closed in the orientation illustrated in FIGS. 1-3, the door 30 extends beneath the bottom 28 in alignment with the pair of upper channels 26. When the second container 14 is mounted with its flanges 20 situated in the upper channels 26, and when the door 30 is closed in the orientation illustrated in FIGS. 1-3, the door blocks removal of the container 14 from the container 12. The door 30 therefore acts as a stop when the door is closed. When the door is opened, however, the container 14 may readily be removed from its engaged position in the upper channels 26.
When the container 14 is oriented with its flanges 20 in the lower pair of channels 22, however, opening or closing of the door 30 has no affect, as best shown in FIGS. 1 and 2. The lower channels 22 are formed in the brackets 24 such that when the door 30 is closed, the channels 22 are visible and accessible beneath the door. Therefore, the second container 14 can be installed in or removed from the lowered channels 22 without the necessity of opening the door 30.
Extending from the bottom of the door 30 are a pair of detents 38. A detent 38 is best shown in FIG. 6 as it extends from a bottom flange 40 of the door 30.
Each detent 38 includes an inlet ramp 42 and an outlet ramp 44. A heel 46 extends from the outlet ramp 44 to the flange 40. Preferably, the inlet ramp 42 and the outlet ramp 44 are formed at an angle of about 30.degree. to horizontal.
With the door 30 closed in the orientation shown in FIGS. 1-3, and with the second container 14 located in the lower channels 22, the detents 38 serve to temporarily hold the second container 14 in place. Thus, when gloves or other items are pulled from the dispensing slot 18, the second container 14 is blocked by the detents from being inadvertently pulled from its mounting in the lower channels 22. However, since the second container 14 is preferably made of plastic, while the detents 38 interfere with removal of the container 14 from the lower channels 22, the plastic material of the container 14 gives sufficiently so that with a predetermined amount of force, the second container 14 can easily be removed from its location in the lower channels 22 without opening of the door 30. Thus, the detents 38 only temporarily hold the container 14 in place when installed in the lower pair of channels 22, while the door 30 itself prevents the container 14 from being removed all together when the door 30 is closed and the container 14 is located in the upper channels 26.
In the normal preferred orientation of the detents 38, and with the second container 14 being located in the lower channels 22, the top of the second container 14 extends immediately below the heel 46, and therefore engages only the outlet ramp 44 when the door 30 is closed. When the second container 14 is located in the upper channels 26, however, the heel 46 further helps lock the container 14 in place until the door 30 is opened.
The container 12 includes a lock 34 in the door 30 for securing the door 30 in the closed orientation. The lock 34 therefore serves to protect both the contents of the first container 12 and also to prevent removal of the second container 14 when situated in the upper channels 26 by preventing opening of the door 30. As illustrated, the bottom 28 of the container 12 is generally flat, and the top of the container 14 is generally complementary to that configuration so that the two containers 12 and 14 may be joined without interference. The top of the container 14 may be open to readily permit insertion of a box of gloves, tissues or other items, or may be closed or partially closed, depending on the intended usage of the container 14. The door 30 is generally perpendicular to the juncture of the two containers 12 and 14 in order to provide the necessary inhibiting stop to removal from the upper channels 26 when the door 30 is closed.
The door 30 illustrated in FIG. 1 includes a viewing port or window 36 to permit viewing of the contents of the container 16. Obviously, the window 36 forms no part of the present invention, and can be used or omitted, as desired.
Various changes can be made to the invention without departing from the spirit thereof or scope of the following claims.
