ing the under-coated disc within bottles continuously fed
to said third station, and discharging the bottles at a
fourth station ready for ?lling.
In keeping with the objects of the invention, a device
for carrying out the steps of such a process should be
capable of performing such acts quickly, conveniently
and in an uncomplicated manner and further should have
provision both for controlling the application of the ad
hesive to the underside of the discs and for preventing
waste and/or mess in connection therewith.

In accordance therewith, the present invention con
viding bottles, vials or other containers with cushioning
inserts secured to the bottom wall thereof.
In the packaging of items such as solid pharmaceuti
cal preparations which have been compressed into thin,
frangible soluble Wafers or discs, it is obviously desirable
that they be carefully packed in a container and in such
a way that there will be a minimum of breakage of the
wafers during shipment due to sudden shock, jarring or
the like. Conven-tionally such wafers have ‘been loaded
into a bottle or other container of cylindrical shape hav
ing an internal diameter roughly equal to the diameter
of the wafers so that when packed therein, one over the
other, the resultant column of wafers will compactly ?ll
the container and there will be little opportunity for the
wafers to break by shifting within the containers.

rality of vertically reciprocating carrier members ar
ranged about its periphery to travel in a circular path by
continuous rotation of the device and each such carrier
members having sharpened means on its lower end which
may be forced into one of such plastic cushion inserts or
discs so as to separate it from a supply thereof, properly
center it relative to said carrier member and, as the de
vice is rotated, carry the insert or disc past a second sta
tion where there is located a fount of continuously ?ow
ing adhesive, for example heated ?uid wax and thence to
a loading station for insertion into a waiting bottle or
container.
The invention further contemplates that at said second
station, ‘means are provided for lowering each insert into
it also has been proposed to insert a disc-like cushion
of foamed plastic of the type as for example known as
Styrofoam at each end of the column of wafers as means
to absorb sudden shock and thus further protecting the
the rising fount of adhesive when immediately in posi
this happens, it, of course, interrupts the packaging pro
ing device. At said station, the invention contemplates

reach of the adhesive so as to con?ne the application of

packed frangible wafers against breakage. However, in

The invention contemplates that the loading device as
is rested on its side in a horizontal position to receive the

by means of the carrier members on which they are tem
previously inserted into the bottle to lie between the

erly function in said turned position ‘but also takes up

more than its intended share of the storage area in the
container and the requisite number of wafers cannot be
added.
it is therefore a principal object of the present inven
tion to provide convenient means and method of locat
ing and/or securing such cushions or other inserts into
bottles or other containers whereby they will stay in place
against the bottom ‘surface of such containers as when
the containers are laid on their sides in a horizontal po
sition for ?lling with waters as aforedescribed.
Another object of the invention is to provide commer
cially practicable means and method of securing such
cushioning discs of multicellular or foamed plastic to
the bottom wall of a container.
in accomplishing the aforesaid broadly stated objects,
further more speci?c objects of the invention include
provision of a device which will both load the contain
ers with cushion discs and will also secure the cushion
discs to the bottom wall of said containers, as by prior
application of a thickness of suitable adhesive to the un
?cient to carry the inserts through the open mouth of
the aligned bottles and to discharge the cushion inserts
against the bottom wall of said bottles and then to re
tract the carrier members, minus the cushion inserts, from
the bottles and return them to their original height. The
speed of the overall operation and the temperature of
the heated wax or other adhesive are so related that the
adhesive applied to the bottom of he insert remains in
50 a heated soft stage until the insert has been discharged
from the carrier into engagement with the bottom wall
of the bottle whereby upon cooling it will bond the in
sert to said bottom wall. Although no part of the pres
ent invention, it is contemplated that on withdrawal of
the carriers from the bottles, these bottles will then be
carried by appropriate means to the next operation which
presumedly will be loading the bottles with the afore
mentioned frangible wafers of compressed material.
Therefore a further and broad object of the invention
is to provide conveniently operable, non clogging means
for dispensing controlled amounts of an adhesive such
derside of the cushion discs, and which device will ac
as paraffin wax which has been heated to a ?uid state
complish such acts quickly, conveniently, automatically
on to the underside of each said plastic inserts.
Another object is to- provide means for conveniently
and in a simple, practical and e?icient manner.
A still further speci?c object is to provide a process, 65 retrieving the ejected adhesive which does not adhere
to the underside of the foamed plastic inserts and return

engaging the upper side of a cushion and which carrier
is movable to carry said means across one station to
a further station where said means is caused to release
its hold on the cushion and to locate it within a waiting
container, said one station including a jet from which
rises a fountain of heated adhesive in fluid form, and
means acting on said carrier for temporarily lowering
said ?rst means over the fountain and immediately with
drawing the same so as to control the deposit of heated
adhesive on the underside of a cushion carried by said 10
means.
Thus one of the important features of the invention is
that not only are each of the cushions automatically
coated on their underside with the heated adhesive be
fore being positioned into the bottles, but the manner
and extent of depositing the adhesive on said underside
of the cushions is so enforced that the adhesive deposit
occupies only the central portion of the underside of the
cushion and there is no adhesive at the edges of the
cushion or on its sides which will smear the bottles into
which it is discharged or will otherwise provide an un
sightly or undesired effect.

Because of the uneven character of the bottom wall of

more desirable to have the carrier 60 bring the disc C
