Claims
What is claimed is:
1. A container means for perdetermined unit dosages of
pharmaceutical materials adapted to be received in a loading tray
means provided with spaced container receiving openings disposed on
the upward facing surface of the tray comprising, in combination, a
plurality of open-mouth containers, each provided with a
surrounding integrally formed lip portion removably connected to
the lip portion of the next adjacent container, each of said lip
portions being provided with an upwardly facing recess having a
substantially semi-circular configuration formed integrally with
the opposing upper edge portions of the mouth of said container,
said recesses forming protrusions of complementary shape on the
underside of the lip portions which are adapted to be resiliently
seated within a recess of a like container disposed in nested
relationship below; and a flat elongate strip of material removably
disposed over each of said containers and carrying indicia
identifying the contents of each container, said elongate strip
including breakaway connections disposed between each container.
Description
BACKGROUND
The present invention relates generally to containers and
particularly to container means specifically adapted for the
efficient distribution of predetermined dosage units of
pharmaceutical materials.
The distribution of pharmaceutical materials to bed patients in
nursing homes and other similar institutions is usually undertaken
by individual pharmacies. The nature of this type of distribution
presents many problems both to the pharmacist and to the personnel
of the institution. The large number of patients, the frequency of
the required dosages, and the inherent importance of accuracy and
control in preparing and distributing the proper doses magnifies
these problems.
There has been developed a novel distribution system wherein many
of the problems inherent in the distribution of pharmaceuticals to
large institutions has been substantially reduced. This system is
based upon permitting the pharmacist to prepare a large number of
dosage units of specific pharmaceuticals is an efficient, accurate
manner which also aids the nursing personnel to distribute the
dosages to the patients.
However, the container means of the present invention was
specifically designed to permit a pharmacist to prepare individual
dosage units for delivery to the institutions in an efficient and
economically feasible manner to reduce the former time consuming
and burdensome task of the nursing personnel and to permit more
efficient control over the preparation and distribution of
individual dosage units.
SUMMARY OF INVENTION
The container means of the present invention comprises a plurality
of containers removably connected to one another to form strips.
Each container includes an integrally formed lip portion provided
with a downwardly extending recess on opposing sides of the
container opening which form downwardly extending protrusions on
the lower side of the lip portions. This construction permits the
containers to be partially nestable for bulk shipping and storage.
However, in cooperation with a tray used for preparing the dosage
units or their distribution, the protrusions prevent the container
from fully seating in the tray opening for more convenient handling
by the pharmacist and the nursing personnel.
In addition, an elongate cover strip with prestamped or typed
indicia is removably disposed over the lip portion after the
containers have been filled with the desired dosage unit. Once a
strip of containers has been so prepared, individual containers may
be easily disconnected from one another.
OBJECTS
It is therefore an object of the present invention to provide
containers means for pharmaceutical materials which greatly reduces
the time required in preparing and distributing pharmaceutical
materials in predetermined dosage units.
It is another object of the present invention to provide container
means which greatly reduce the chances of error occurring in the
preparation of a predetermined dosage unit and also in the
distribution of the proper dosage unit to the patient.
It is another object of the present invention to provide a
container means of the type described which may be manufactured at
relatively low cost using standard procedure.
It is a further object of the present invention to provide a
pharmaceutical container means of the type described in which the
construction in cooperation with a suitable tray or holding means
provides ease and convenience in handling and yet permits nesting
of large bulk quantities of containers for shipping and storage
convenience.

DETAILED DESCRIPTION
Referring in detail to the drawings, a strip of pharmaceutical
container means, indicated generally at 20 and constructed in
accordance with the present invention is illustrated in FIG. 1 and
includes a plurality of containers 22, preferably a predetermined
number, removably connected to one another.
Each container 22 includes an integrally formed, thin lip portion
24 in surrounding relationship to a cup portion 26.
Lip portion 24 of each container 22 is detachably connected to an
adjacent container 22 in tearaway fashion to permit convenient
removal of a single container from a strip of containers.
Preferably the container 20 is formed from a clear plastic material
such as cellulose acetate or the like using a standard vacuum
molding process.
An elongate label strip 30 is preferably placed over the openings
of each container 22 to function as a closure after the medicinal
dosage has been placed in each row of containers which are placed
in a loading tray 42 as shown in FIG. 1.
Label strip 30 preferably is comprised of sheet material such as
paper or the like having one side processed with an adhesive
material along at least two opposite edge portions approximately
coinciding with opposing lip portions 24. The strip 30 is also
provided with indicia 32 spaced to coincide with each container 22
to indiciate the kind and dosage of the pharmaceutical material
disposed in each container.
Strip 30 is also provided with narrowed neck portions 34 positioned
between each container to approximately coincide with tearaway
portions provided in lip portion 24 to permit the portion of strip
30 between adjacent neck portions 34 to be easily torn away from
the adjacent containers 22 comprising container means 20.
Each lip portion 24 of each container 22 includes an integrally
formed substantially semi-circular recess 36 on the top surface of
opposing side portions which form corresponding protrusions on the
underside of the lip portion.
This provides a very important feature in the manufacture, shipping
and storage of the containers in addition to providing ease of
handling in use by the pharmacist.
In shipment of large quantities of these containers 22, they are
readily partially nestable during transit and after receipt by the
pharmacist, for storage purposes, as shown in FIG. 3 to provide a
substantial economy of space.
The upper adjacent container 22 partially nests in the lower
adjacent container with the protrusions of the underside of lip
portion 24 on the upper container mating with the recesses 36 on
the upper surface of the lower adjacent container.
However, it is important to point out that each container does not
fully nest in the lower adjacent container. Therefore a strip of
containers may be very conveniently removed from the stack of
partially nested containers with great ease and facility. If the
container fully nested within one another as do conventional
containers, the relatively thin lip portions make it relatively
difficult to separate one strip of containers from another. This is
time-consuming and frustrating to the user in dealing with a large
volume order. A saving of a small amount of time and the added
convenience become important factors throughout a working day.
However, when a strip of containers 22 are removed for placement in
a loading tray such as 42 in preparation of a volume order of unit
doses of a given pharmaceutical, each container 22 is prevented
from fully seating in the respective recess in the tray by the
protrusions 36 on the lower side of lip portion 24. Therefore the
lip portion 24 is raised slightly above the top surface of the tray
for convenient removal by the user as best seen in FIG. 5.
This same feature is very convenient when the filled containers are
disposed in distributing trays, similar to the loading trays, for
distribution of individual dosage units to patients by the nursing
personnel of a large institution.
