This invention relates to improvements in the
art of packaging and dispensing ?uent commodi
A general object of the present invention is
5 to provide an improved method of and means for
packaging a ?uent commodity in a sealed con
tainer and in subsequently providinga discharge
opening in the container and manipulating the
container in a manner so as to forcibly dis
10 charge some of the commodity directly therefrom
through the opening in'the form of a spray or

of the bodyof these containers are closed by
metal caps which are crimped or-clamped into

cap applying machinery, which is a draw-back
and disadvantage.
With reference to the'present invention, it is
a more speci?c object to provide a paper board
container especially adapted for the ‘packaging
of oil, and overcoming the» above objections by
virtue of constructional‘features which eliminate .10
the possibility of oil leakageixor seepage, the
A further object of the invention is to provide container furthermore being of'such a charac
ter that the manufacturerv can, originally apply
a method of and means for packaging a fluent,

A further ‘object of the invention is to provide
A further object of the invention is to provide
paper board containerespecially adapted for 20
a container, generally of paper board construc
tion, which may be readily initially ?lled or the packaging of oil, which meets all of the
requirements as to being light, durable, non

and inexpensive.

be subjected to a certain manipulation so as to
25 forcibly eject -material directly from the vcon
tainer in the form of a spray or stream, the a paper board container of the character de- 25
container'being of a character so as to preclude scribed, which after being opened for dispensing
its being refilled, and furthermore being very
inexpensive so that it may be discarded after the
contents have been discharged therefrom.
As a more speci?c aspect of the ‘invention, itis
contemplated that the present method and con
tainer per se are especially adaptable for use in
connection with the vending of oil. Recently,
35 oil companies have found it very desirable to
vend oil in containers formed of paper board.
It is desirable that the paper board container
for this purpose have metallic ends, one of which
is opened or mutilated for dispensing purposes.
40 Paper board containers of this general type are
very advantageous because they are non-re?ll
able and therefore cannot be re-used with a sub
stitute or inferior commodity, are easily disposed
of, are cheap, and arelight. The major objec
45 tions, heretofore, to this type of an oil container
reside in the fact that oil is very di?icult to pack
and store because it has great seeping and leak
ing tendencies, and in this general class of con
tainers, when used for oil, the walls of the con
50 tainers have been marred and rendered unsightly '
by virtue of oil soaking through the paper board
walls thereof, andalso seepage and leakage of
oil has been found to occur» at the junction of
the metal caps with the ends of the paper board
55 body. In addition, due to the fact that the ends
purposes may be used in the nature of a pump "
so as to forcibly eject oil therefrom whereby the
contents of the container may be easily and rap
idly exhausted.
.A further object of the invention is to provide
a paper board lubricant container which. may
have interchangeable ?ttings applied to the dis
charge end. thereof to adapt the container to
the forceful dispensing of various types of lubri
cant directly into the various portions of a motor
vehicle, such as the crank case, transmission,__o'r
the differential.
A further object of the invention is to provide
a method of and means for packaging and dis 40
pensing a ?uent commodity which is very simple,
which is inexpensive and expeditious, and which
is well adapted for the purposes vset forth. ~
With the above and. other objects ‘in view, the
invention consists of the improved method of 45
and means for packaging and dispensing fluent
commodities, and its parts, combinations,‘ and
steps, as set forth in the claims and all equiva

then discarded and may be readily destroyed. It
cannot be re?lled or re-used because the metallic
35 end thereof has been ruptured and opened for
dispensing purposes.
In Fig. 6 a slightly modi?ed form of appliance
21’ is illustrated in its application to the dis
charge end of the container. This appliance 21'
40 is especially adapted for use in connection with
introducing the contents of the container into the
differential or a like portion of a vehicle. The
appliance 2'!’ has a cupped portion 28' which
is frictionally ?t onto and over the opened end
45 portion of the container, as shown in Fig. 6. The
?at end wall of the appliance 21' has a central
discharge opening therein, from which a tubular
stub 30' projects outwardly. The outer end of
the stub 30' is externally threaded as at 32 to
50 receive the internally threaded inner end of a
hook shaped discharge nozzle 3|’. In use said
nozzle 3|’ is introduced into the opening into
which lubricant is to be forced, and the container
is reciprocated back and forth telescopically to
55 pump out the contents through the stub 30' and
nozzle 3|’. If desired the appliance 21' may be
equipped with an air vent 33 which will be lo
cated over the rupture 26 in the container end.
The ori?ce 34 in said vent 33 is normally closed
60 by a ball valve 35 to prevent the ?o'w of lubricant
therethrough, but said ball valve can move away
from the ori?ce 34 to admit air to facilitate the
pumping operations.
A modi?ed form of container is shown in Figs.
65 '7 to 10 inclusive. This form of container is
especially adapted for the packaging of ?uent
commodities of a granular nature wherein'the
concern regarding leakage and seepage is not
acute. Said form of container comprises an outer
70 cylindrical section l5’ closed at its outer end by
a metallic cap I1’ and an inner cylindrical sec
tion l6’ having its outer end portion surrounded
by a collar 2|’, the outer end of which has
clinched thereto a metallic end cap 23’ whose
75 inner peripheral portion seats against the
that‘ with the present invention a suitable com- '
modity can be originally packed in the container
in a very convenient and expeditious manner
without the necessity of special tools, equipment
or appliances. When the commodity is thus
packaged it is presented to the consumer in an
attractive sealed manner, and the package is of
such a nature that re-use or re?lling of the same .
With an inferioror substitute commodity is pre
cluded. In addition, the consumer can dispense
the commodity directly from the container in a
convenient spray or stream form under pressure,
by using the container itself asgar pumping or force
impelling medium. The container is relatively in
expensive to manufacture, and after the contents
have been exhausted therefrom it may be readily
discarded and disposed of.
.While the particular embodiments of the in- ,_
vention have been set forth for the purpose of

be limited precisely thereto, and all changes and
