Description
BACKGROUND OF THE INVENTION
Individual beverage containers for human beings are in extremely
widespread use. In recent years the tendency has been to employ
cylindrical shaped beverage containers which are commonly referred
to as cans. Such can-type containers have proved to be most
desirable since such do not break as does glass. Cooling of the
liquid contained within the cans is facilitated as the metallic
cans facilitate heat transfer, and such cans facilitate portability
and storage thereof. Also, with the advent in recent years of the
snap top opener employed in combination with a can, the use of such
cans has greatly increased because of the need for a separate
opening apparatus has been eliminated. The use of such can
containers facilitates the distributing of beverages at public
gatherings. For example, where beverages are sold to the public at
places of entertainment such as sports events, the use of such can
containers substantially decreases the serving time for each
individual.
It is the normal procedure in the serving of beverages to people
for the people to move to and from the serving location, the
serving location remaining stationary. However, in aircraft the
situation is just the reverse. The stewardesses are required to
move down the aisles of the aircraft and serve the passengers who
remain in their seats. Heretofore, it has been common for the
stewardess to move progressively down the aisle asking the
passengers what type of beverage he would prefer, with the
stewardess then walking back to the galley, securing the particular
desired beverage, and then walking back to the particular
individual to serve the person. Obviously, such a procedure is
quite time consuming.
Within recent years, the flight time of aircraft has been steadily
diminishing. Also, the number of passengers within each particular
aircraft has been steadily increasing. Therefore, some means must
be employed to facilitate the dispensing of canned beverages which
would permit the stewardess to serve the passengers over a much
shorter period of time.
Recently, stewardesses have started to employ the use of carts
wherein the cart can be moved progressively down the aisle within
the aircraft with the cart carrying a plurality of can-type
beverage containers. Because of the wide choice available to the
passenger of different types of beverages, the stewardess must
carry within the cart a plurality of different types of beverages
as well as a plurality of individual cans within each type of
beverage. As a result, the stewardess is required to have at her
disposal within the cart a substantial number of beverage cans,
many of which will not be selected. In an effort to facilitate the
dispensing of such can containers, lever actuated types of
dispensing devices have been employed. Frequently, such devices
relay on the fact of using the bead portion of the containers, it
being common for most can containers to have an upper or lower
bead. However, in recent years can-type containers are being made
without such a bead. Therefore, such bead-type dispensing devices
have been proved to be not usable. Also, such lever systems employ
linkages which frequently require maintenance and repair.
It would be desirable to employ the use of a dispensing mechanism
for can-type beverage containers in combination with a removable
cart within an aircraft, wherein a substantial variety of types of
beverages are made available, a plurality of cans of each type of
beverage is carried by the cart, and the dispensing of such cans by
the stewardess is accomplished with ease.
SUMMARY OF THE INVENTION
The dispensing apparatus of this invention is designed to be
employed in combination with a movable cart mounted at a
substantially vertical manner. A plurality of beverage containers
are to be stacked, one on top of the other within the housing of
the dispensing apparatus. An axial spring biasing means is to be
located within the lower end of the housing, the upper end of which
is secured to a movable platform which is snugly movable within the
housing. The open end of the housing has a stop lip which is
adapted to cooperate with the uppermost container of the stack to
prevent such from being removed from the housing. A lateral spring
cooperates with an aperture within the housing adjacent to the open
end and functions to insure that the uppermost container cooperates
with the stop lip. The diameter of the housing is to be a
predetermined amount larger than the diameter of each of the
containers. Thereby, the uppermost container is manually movable
against the bias of the side spring and is capable of being moved
past the stop lip. At the same time of the tilting of the uppermost
container, the container located directly under the uppermost
container is tilted in the opposite direction permitting such to
easily pass the side spring. The movable platform which cooperates
with the axial spring bias is not capable of passing the side
spring.

DETAILED DESCRIPTION OF THE SHOWN EMBODIMENT
Referring particularly to the drawings there is shown in FIG. 1 a
dispensing apparatus 10 of this invention having a cylindrical
shaped housing 12 which is to be employed to retain a plurality of
beverage containers 14 stacked on top of each other. It is to be
understood that the length of housing 12 is to be strictly a matter
of choice or design. It is considered that the length of housing 12
will be of sufficient length to retain four or five containers 14.
However, the length could be easily increased to retain as many as
10 or 12 containers 14 or could be of a lesser length to contain
only two or three containers. It is also envisioned that a
plurality of such dispensing apparatuses 10 will be employed within
a single element such as a movable cart. The movable cart would be
employed within an aircraft and movable down the aisles thereof
between the passengers' seats. It is envisioned that four such
dispensing apparatuses 10 will be employed in combination with each
cart, each dispensing apparatus 10 to be employed to dispense a
different type of beverage container 14. However, again the number
of dispensing apparatuses 10 to be employed within each cart will
be strictly a matter of choice or design.
The uppermost end of housing 12 is open at 16. A stop lip 18
extends across a portion of opening 16 and is secured to housing
12. An aperture 20 is formed within the side of housing 12 and
spaced from opening 16 approximately the distance equal to one-half
the length of container 14. Also, the aperture 20 is located
substantially diametrically opposite stop lip 18. A friction
element 22 is movable within aperture 20 with the friction element
being secured to side spring 24. Side spring 24 is attached by
rivets 26 to a housing 12. It is to be seen within FIG. 1 of the
drawings that rivet 26 is located relatively close to friction
element 22. As a result, initial movement against the bias of side
spring 24 is accomplished with ease and upon continued movement,
the bias becomes substantially greater. The reason for this will be
explained further along in the specification.
The material of construction for friction element 22 is to be
considered a matter of choice or design. However, a satisfactory
form of material would be a form of plastic material and actually
the form of plastic which is commonly referred to as under the
trade name of Teflon. Also, although friction element 22 is shown
to have a pointed end which will come into contact with container
14, it has been found that such a point contact relationship with
the container 14 facilitates its movement past friction element 22.
However, other configurations of element 22 may be employed.
Spring 28 is axially located within housing 12 and fixedly secured
at the lower end thereof. Spring 28 is secured to a platform 30 at
its upper end thereof. Platform 30 is of such a diameter so as to
be snugly, but easily movably retained within housing 12. This
arrangement is particularly important to the operation of this
invention. The diameter of housing 12, as is shown in FIG. 2 of the
drawings, is such as to retain containers 14 in rather loose
fitting arrangement. Again, this feature is an important aspect to
the operation of this invention.
The operation of the dispensing apparatus of this invention is as
follows: It will be assumed that the dispensing apparatus 10 of
this invention is located within a movable cart which is positioned
within an aircraft. It also will be assumed that the dispensing
apparatus 10 is empty as shown in FIG. 5 of the drawings. In this
empty position, the upper edge of the platform 30 is in contactual
relationship with friction element 22. It therefore is prevented
from further upward movement by means of the biasing action of
spring 28. To load the apparatus 10, the stewardess then grasps an
individual container 14 and inserts it within housing 12, past stop
lip 18. As a result, platform 30 is moved downwardly against the
bias of spring 28. Once the first container 14 is so located as
shown in FIG. 3 of the drawings, the friction element 22, by means
of side spring 24, exerts a lateral bias against the container 14
tending to maintain the upper edge thereof in contact with stop lip
18. A Stewardess will then grasp another container 14 and insert
such in the same manner as was described for the first container.
This procedure is again repeated until the desired number of
containers 14 are located within the apparatus 10. It is envisioned
that the apparatus 10 can be mounted in a vertical direction with
removal of the containers 14 being effective against the pull of
gravity. As the spring 28 is compressed further upon inserting of
an additional container 14, the spring assumes a greater biasing
action. However, a greater load, because of the weight of each
additional container 14, is placed upon the spring 28. As a result,
a self-compensating action is achieved wherein the uppermost
container 14 is retained against lip 18 with approximately the same
degree of force at all times. Such a constant spring force
facilitates the removal of the containers 14.
With the container 14 so located within the dispensing apparatus
10, the stewardess can then move her cart down the aisle of the
aircraft adjacent a particular passenger location. Upon obtaining
the particular beverage choice from the passenger, the stewardess
then exerts a manual force against the uppermost container 14,
tilting the container 14 until it is unassociated with the lower
surface of stop lip 18. The spring 28 then biases the uppermost
container 14 effecting disassociation from the dispensing apparatus
10 as shown in FIG. 1 of the drawings. Also, upon the tilting
action of the uppermost container 14 to remove such, the container
located directly beneath the uppermost container is tilted in the
opposite direction as shown in FIG. 2 of the drawings. This
opposite directional tilt facilitates the passage of such past the
friction element 22. Upon the uppermost container 14 having been
removed, the spring bias from spring 28 pushes all the containers
in the stack in an upward direction until the container now at the
top of the stack comes into contact with stop lip 18. Contact with
stop lip 18 is assured because of the lateral bias caused by side
spring 24 through friction element 22 upon the upper container 14.
The arrangement of side spring 24 is such that during movement of
the containers 14 in the upward direction into contact with the
stop lip 18, a quite small amount of biasing force is exerted
against the container 14 so as to not significantly hinder movement
thereof. However, during tilting of the uppermost can 14 to remove
such from contact with stop lip 18, the lateral biasing force of
the spring 24 increases rapidly. Such a force is not great enough
as to hinder removal of the uppermost container 14, but does ensure
that in all instances the next succeeding container 14 will come
into contactual relationship with stop lip 18 and not be
accidentally discharged through opening 16 exteriorly of the
dispensing apparatus 10. In other words, upon employment of the
apparatus 10 of this invention, absolute dispensing of beverage
containers 14 on an individual basis is ensured.
Upon the last container 14 being removed from the housing 12 of the
apparatus 10, the platform 30 comes into contact with the lower
edge of the friction element 22. Therefore, further movement of the
platform 30 by the action of the spring 28 is prevented into the
upper area of the housing 12 adjacent open end 16. By the platform
being displaced from open end 16, relocating of containers 14 is
facilitated within the apparatus 10.
The apparatus 10 of this invention does not rely upon beaded edges
of the containers 14 to effect their retention thereof within the
apparatus 10. Dispensing apparatuses of the prior art do so rely
upon the beaded portions of the container 14. In actual practice, a
greater number of containers do not have upper and lower beaded
edges; therefore, the dispensing apparatuses of the prior art are
not capable of being employed with such beaded containers. The
dispensing apparatus of this invention does not in any way rely
upon beaded edges of the container 14 and actually may be employed
in combination with containers with beaded edges or without beaded
edges.
