TWO-PART TABLET DISPENSING RECEPTACLE
Abstract
A two-part tablet dispensing receptacle comprises a housing
having a dispensing end and a pivotal cover at the dispensing end.
A stack of tablets in the receptacle is pressed towards the
dispensing end, and a spring biases the pivotal cover into a closed
position, the cover having a portion pushing the upper-most tablet
and dispensing it from the receptacle when the cover is pivoted
against the spring bias. The cover has side walls and the spring is
an extension of one of the cover side walls.

The present application is a division of my copending application
Ser. No. 300,487, filed Oct. 25, 1972.
Claims
What is claimed is:
1. A two-part receptacle for receiving and sequentially dispensing
individual shaped bodies from a stack of like ones of said bodies
received in the receptacle, one of the receptacle parts being a
housing having a dispensing end and the other receptacle part being
a cover having side walls at the dispensing end, pivot means
connecting said housing and said cover, spring means in the housing
for pressing the stack of shaped bodies towards the dispensing end
to place sequential uppermost ones of the shaped bodies of the
stack into a dispensing position, a spring contacting said housing
at a position remote from said pivot means, and being constituted
by an extension of one of the cover side walls biasing the pivotal
cover into a closed position, and the cover having a portion
pushing the uppermost shaped body and dispensing it from the
receptacle when the cover is pivoted against the spring bias.
2. The two-part receptacle of claim 1, further comprising a
laterally open drawer in the receptacle housing, the cover
extension constituting the spring extending into a space between
the drawer and the housing and engaging the wall of the housing.
Description
The present invention relates to improvements in receptacles for
receiving and sequentially dispensing individual shaped bodies from
a stack of like shaped bodies received in the receptacle.
Austrian Pat. No. 166,326 and corresponding U.S. Pat. No. 2,620,061
discloses a receptacle, one of the receptacle parts being a housing
having a dispensing end and the other receptacle part being a
pivotal cover at the dispensing end. Spring means in the housing
presses the stack of shaped bodies, such as tablets, towards the
dispensing end to place sequential uppermost shaped bodies of the
stack into a dispensing position, a spring biases the pivotal cover
into a closed position, and the cover has a portion pushing the
uppermost shaped body and dispensing it from the receptacle when
the cover is pivoted against the spring bias.
This type of dispensing receptacle has found wide commercial
acceptance for use with a great variety of tablets. The receptacle
disclosed in the indicated patents carries a laterally open drawer
within the receptacle housing, a spring-biased bottom for the
drawer which presses the stack of tablets towards the dispensing
end of the housing, and the side walls of the receptacle housing
have extensions at the dispensing end which supports the cover.
Another part of the receptacle is the cover spring. All the parts
of the receptacle are assembled manually. Considering the steady
increase in wages for manual labor, this has made the manufacture
of these receptacles correspondingly more expensive.
It is the primary object of this invention to overcome this
disadvantage in the manufacture of receptacles of the indicated
type and to simplify the assembly of the receptacle parts, more
particularly by doing away with a separate cover spring whose
assembly involved an especially time-consuming operation.
The above and other objects are accomplished in accordance with the
invention by making the spring which biases the pivotal cover into
a closed position integral with the cover of the receptacle.
According to a preferred embodiment of the present invention, the
receptacle part integral with the spring is an injection molded
thermoplastic resin body, for instance of polystyrene.
According to this invention, the spring is an extension of one of
the side walls of the cover.
The above and other objects, advantages and features of the present
invention will become more fully understood by reference to the
following detailed description of certain now preferred embodiments
thereof, taken in conjunction with the accompanying drawing
wherein
FIG. 1 is a longitudinal section along line I--I of FIG. 2 of a
receptacle according to this invention; and
FIG. 2 is a transverse section along line II--II of FIG. 1.
Referring now the drawing, the receptacle is shown to comprise a
housing 1 receiving a stack of like tablets 2 which are
sequentially dispensed from the receptacle. A spring means
constituted by compression spring 3 is mounted in the receptacle
housing 1 between a fixed bottom 6 and a movable tablet stack
support bottom 5 for pressing the stack of tablets 2 towards the
dispensing end of the receptacle housing to place sequential
uppermost tablets of the stack into a dispensing position.
The assembly of the housing with the cover is very simple. The side
walls of the cover are slightly spread to fit the bearing bores
thereof over the pivot pins 8 of the housing side wall extensions.
This is all that is required and no extra spring assembly is
involved. This makes the manufacture of the receptacle so
inexpensive that it may be offered as a disposable receptacle for
dispensing tablets. The spring 21 certainly remains operable for
such limited use but experiments have shown that this type of
receptacle will continue to function without spring failure even
when refilled a number of times.
The illustrated embodiment is particularly useful in connection
with the known type of receptacle wherein a laterally open drawer
is in the housing. In this embodiment, at least one of the side
walls of the pivotal cover 20 has an extension 21 which constitutes
the spring which biases the cover into a closed position and which
is integral with the cover.
As shown in FIG. 2, the spring 21 extends into a space between the
drawer 23 and the housing 22 and engages the front wall 25 of the
housing (see FIG. 1). Thus, the spring biases the cover
counterclockwise into its closed position and is deformed when the
cover is opened by clockwise pivoting in the direction of the
arrow, the spring material being chosen to be of such elasticity as
to function in the desired manner. The longer the spring the longer
lasting its operating life. Thus, this embodiment provides
receptacles having a long life while still doing away with a
separate wire spring, with its attendant assembly problems.
While it may be most economical to make at least that part of the
receptacle which is integral with the cover spring of thermoplastic
resin of required rigidity, since injection molding is inexpensive,
other suitable materials, such as sheet metal, may be used. As to
thermoplastic resins, all those may be used which are rigid under
ambient temperatures but permit of some elastic deformation without
breaking. Since most thermoplastic resins are commercially avilable
in various forms of rigidity, the proper material may be readily
selected by those skilled in the art.
The particular cross section of the receptacle may be freely chosen
although a rectangular cross section has been illustrated.
