This inventionv relates to means for dispensing
liquid from sealed metal cans, and more par
ticularly to such a device for dispensing lubricat
ing oil at automobile ?lling and service stations.
invention consists in the oil dispenser elements
and their relation one to the other, as herein
Lubricating oil is often dispensed at ?lling
stations, service stations, and theI like, from
speci?cation and sought to be de?ned in the
claims. The speci?cation is accompanied by
sealed metal cans or containers.
drawing in which:
To facilitate
emptying such containers it has heretofore been
proposed to use funnel-like devices adapted to
10 receive one end of the can and provided with
one or two cutters or punches for puncturing
the end of the can. Such devices suffer from a
number of disadvantages, which need not be de
tailed except one concerning re?lling of the can.
Obviously the merchandising in sealed cans is
intended to prevent the substitution of an in
ferior oil. If only the end of the can is perfo
rated, the can may be re?lled and a new end
placed on the can, or the opening repaired, or
20 the can may be left unrepaired and perforated,
in which case an unscrupulous dealer can apply
the funnel or dispensing device to the perforated
can unless followed and closely watched by the
motorist. Accordingly, one primary object of
25 the present invention is to generally improve
these devices, with a View to correcting such
faults and disadvantages. More particularly, one
object of the present invention is to avoid leak
age or spillage of oil when emptying the can and
transferring the oil to the crank case, and with
this object in View I employ an intermediate re
ceptacle or reservoir into which the oil pours from
the perforated can and from which the oil is
readily and conveniently transferred to the crank
35 case. Still another object of the present inven
tion is to completely destroy the can, making the
same useless as a container and thereby wholly
preventing the possibility of re?lling the same.
With this object in view I provide cutting means
and venting means which cut through the side
walls of the can, preferably near opposite ends
of the can. This makes it impossible to recon
struct the can by applying a new end, and im
practicable to repair the can in any manner, and
45 impossible to re?ll the unrepaired can with oil.
Still further objects of the present invention
center ‘about the cutter for perforating the side
after are more particularly described in the
dispensing device constructed in accordance with
my invention;
Fig. 2 is a plan view of the same with the can
removed;
Fig. 3 is a section taken in the plane of the
line 3-3 in Fig. 2;
Fig. 4 is a side elevation of the emptied can; 15
and
Fig. 5 shows the cutter in perspective.
Referring to the drawing, the dispensing de
vice of my invention comprises a receptacle I2
provided with a‘ spout I4 and a handle I6. Com 20
bined with the receptacle are can supporting
and perforating means, the supporting means
being here exempli?ed by the end supports I6
and I8, and the side supports 20. The perforat
ing means includes a main cutter 22 for cuttinga
large drainage hole in the side wall of the can,
and an auxiliary punch or cutter 24 for venting
the can. In operation, it will be understood that
a sealed can 30 is forced into the can supporting
means and is at the same time opened by the
cutter. In one aspect, I provide a dispensing de
vice open at the top and having a cutter. 22 and
guide means I 6,. I8, and 20 to guide the can to
the cutter. The oil drains freely and fully into
the receptacle I2. The device is then applied to
a crank case opening or breather pipe 32 when
the oil is readily and completely emptied from
receptacle i2 into the pipe 32 by tilting the com
plete unit.
Considering the arrangement in greater detail,
the dispensing device preferably consists of a
unitary cast metalybody made, for example, of
an aluminum or other light metal alloy in order
to reduce its weight. The body comprises the
receptacle I2- which is preferably though not
necessarily made generally rectangular in shape,
and which is most desirably provided with a ?atv -

drainage of the oil from behind the tab through
the drainage opening. To facilitate the free flow
of oil from the can downwardly into the recep
tacle I2, the body of the cutter is preferably
skeletonized, the interconnecting wall 60 and the

to an automobile crank case, ?rst, because the
body of the dispensing device is a substantial
distance away from the crank case opening, and,

It will be evident that after a can has been
to permit complete drainage of the oil from the

tilted position. The lowered end of the can is,
of course, disposed above the open top of the
receptacle, and it is this end which is perforated

vention, as Well as the many advantages thereof,
The end l6 consists merely of an end
wall or rest provided with side flanges 44 for
guiding and receiving a can forced into place.
The support member l8 consists merely of an end
35 wall which is stiffened and strengthened by a
web 46 which extends between the handle l6
and the venting means and acts as a support for
the latter. The side supports 20 converge or
slopevtoward one another so as to better ?t and
center the cylindrical can body. The top of re
ceptacle I2 is substantially open between the side
supports 20, but‘the lower end portion of the
opening is provided with inwardly‘ extending
?anges 48 on which the cutter 22 is mounted,
45 while the upper end portion is provided with a
transverse ?ange 50 having a pair of projections
52 for seating and centering the can body.
'
The cutter 22 comprises three cutting edges
arranged in the form of a U and producing
50 the three severances 54, 56 and 58 shown in
Fig. 4 of the drawing. The front wall 50 of the
cutter is trapezoidal in shape, as is best shown in
Fig. 3, the cutting edge 62 thereof being biased
so as to, provide the cutter with a point 64 for
55 readily penetrating the can. The side walls 66
and 68 of the cutter are each generally triangu
lar in shape and slope downwardly respectively
from the lower and higher ends of the cutting
edge 62 to the base 18 of the cutter. The top or
hypotenuse edge of the sides 66 and 68 are sharp
ened to provide sloping cutting edges 12 and 14.
It will be understood from the foregoing descrip
30
will be apparent from the foregoing detailed de
scription. The dispensing device prevents leak
age or spillage because when the can is perfor
ated it is alreadydisposed over a receptacle which 35
receives the oil as it drains from the can. The
can is eifectively destroyed against any possibility
of repair or re?lling, ?rst, because it is perforated
on a side wall rather than an end wall, second,
because it is perforated on the side wall near 40
both ends of the can, and, thirdly, because the
drainage opening is extremely large. The oil
may be transferred to a crank case with great
ease and under perfect control because the re
ceptacle is itself provided with a convenient pour 45
ing spout, and this spout is so designed that the
oil is normally retained in the receptacle yet may
be fully drained from the receptacle by oscillating
the unit upwardly through a relatively small
angle. ,In the speci?c case shown, the dispensing 50
device need only be raised from a horizontal posi
tion through an angle of 45 or 50° to permit
complete emptying of the contents. The can is
fully drained because of the large drainage open
ing-because of the effective venting, and because 55
the cutter is so designed that even the tab of
metal struck ‘upwardly thereby does not obstruct
oil drainage. The cutter itself is operated with
out undue resistance, yet cuts a large opening
and rolls the sheet metal unevenly or slopingly. 60
The body of the cutter is itself skeletonized to
facilitate ?ow of oil therethrough.
It will be understood that while I have de
scribed the dispensing device of my invention as
V employed for dispensing lubricating oil at auto 65
tion and will be evident from an inspection of . V
Fig. 1, that the cutting edges 12 and 14 are sub—
65
stantially different in angular position. The sig
ni?cant thing, however, is that at any particular
level downwardly from the point of the'cutter,
the distance from the edge 14 to the front wall
60 is greater than the distance from edge 12 to
the front wall 60. As a result of this construc
tion they tend to‘ roll up the tab of metal 80, cut
in the side wall of the can, in an uneven or slop

mobile ?lling stations, it may equally well be
employed for the emptying and dispensing of any
liquid from sealed metal cans. It will further be
apparent that while I have shown and described
the structure of my invention in preferred form, 70
many changes ‘and modi?cations may be made
in the said structure without departing from the
ing manner, best shown in Fig. 4, so that the
spirit of the invention, de?ned in the following
