This invention relates to new and useful improvements in means for perforating cans and especially cans containing cofl'ee cream and like liquids which must be poured from the can.

The principal object of the invention is to provide a combination can perforator and holder which in use will serve to permit punching of the can so that the contents thereof can be poured therefrom, while at the same time atfording structure for holding the can while the said contents are being poured.

Another important object of the invention is to provide a device of the character stated which in construction is simple and of low cost to manufacture and which is easily handled and adapted for placement on a can.

Other importantobjects and advantages of the invention will become apparent to the reader of the following specification.

Figure 14 represents an end elevational view of the device shown in Figure 13 and Figure 12.

" Figure 15 represents a fragmentary enlarged 5 detailed sectional view taken substantially on line 5-45 of Figure 13.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the can of conventional 10 construction, such as is used for coflee cream and like liquids. This type of can is provided with a. top 6 which is flexed over the side of the can as at l defining a shoulder 8.

The form of punch and holder shown in Fig- 15 ures 1 to 9 inclusive consists of the primary plate 9 which is substantially of rectangular construction and provided with a pair of spaced leg extensions l0-I0 terminating inwardly directed hook-shaped claws-ll, which are capable of en- 20 gaging under the shoulder 8 in substantially the manner shown in Figures 1, 2 and 3. The plate 9 is provided with an elongated downwardly disposed extension 12, ofiset at its upper end as at Hi to receive the said flange 1. The ex- 25 tension I2 is bent upwardly as at I 4 and then curves outwardly as at l5 and downwardly as at l6 and for a short ways inwardly as at I! to define a handle which can be used to carry the can and the punch about intact with the 30 the tubular punch l9 which when struck through 35 the top 6 of the can provides an air vent.

Numeral 20 represents the secondary plate which as shown in Figure 7 is of substantially rectangular shape, the same being provided with a downturned portion 2| provided with an up- 40 turned lip 22 which engages the shoulder 8 of Y the top 6 in the manner substantially shown in Figure 5. This downturned portion 2| and a substantial portion of the secondary plate 20 is struck out to provide the inclined pouring lip 23. 45 The secondary plate 20 adjacent the lip 23 is provided with an opening 24, from the edge portion of which depends the tubular punch 25 which when struck through the top 6 of the can forms an opening through which the contents of the can can be poured.

The secondary plate 20 is provided with hinge knuckles 26 which can be alined with the spaced barrels 21 on the primary plate 9 and a pin 28 can be disposed through these knuckles and barrels to provide a hinged connection between the primary and secondary plates. It is to be understood that the extension I2 is of spring material so that the primary plate can readily snap in place over the flange portion 1 of the top 6.

Figure 10 shows a slightly modified form of the invention which is only in reference to the secondary plate. In this form of the invention numeral 2|] represents the secondary plate and numeral 2G the hinged knuckles at one end thereof. The outer end of the secondary plate 20 is provided with the can cover engaging hook 22 while adjacent this hook '22 the secondary plate 20 is provided with an upstanding externally threaded neck 30, which engages the connector 3| from which extends the flexible conduit 32. Depending from the under side of the plate 2|] at the neck 30 is the tubular punch 25. This type of secondary plate is specially adapted for use in conjunction with containers for dispensing oil into automobile crank cases.

Another formof the invention is shown in Figure 11 wherein a single plate 33 is employed and provided at one end with an air vent punch 34 and at its opposite end with a tubular punch 35 through which the contents of the can can be poured, and poured over the lip 36 which is struck from this end of the plate 33. One end of the plate 33 is provided with a downwardly extending spring strip 31 which is turned upwardly as at 38 and downwardly again as at 39 to provide the handle 40, while the opposite end of the plate 33 is provided with the downwardly extending leg 4! disposed obliquely at its lower end as at 42 and provided with a shoulder 43 thereon.

The leg 4| is of spring material, so that when the plate 33 is forced downwardly over the top of the can 5 the plungers 34-35 will be driven through the top 6 to provide an air vent opening and. a pouring opening while the shoulder 43 will engage under the flange l and retain this perforator and holder in place.

As is'clearly shown in Figures 5 and 10, the tubular punches 25 and 35 are provided with resilient collars 25 -35, respectively, which bear against the can top over the opening made by the punch to prevent leakage when the can is tilted to pouring position. It can also be seen that the punches 25 and 35 are each provided with an open ng 25 through which the last small quantity of fluid in the case can be poured.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A can perforator and holder comprising a primary plate having a can engaging hook at one end and a depending inwardly disposed spring member at its opposite end for engaging a can, a secondary plate swingably attached at one end to the primary plate, said primary plate being 5' provided with an opening therein, said secondary plate being provided with a tubular punch thereon adapted to be disposed through the opening in the primary plate to pierce the top-of a can engaged by the primary plate.

2. A can perforator and holder comprising a primary plate having a can engaging hook at one end and a depending inwardly disposed spring member at its opposite end for engaging a can,

a secondary plate swingably attached at one end to the primary plate, said primary plate being provided with an opening therein, said secondary plate being provided with a tubular punch thereon adapted to be disposed through the opening in the primary plate to pierce the top of a can engaged by the primary plate, said secondary plate being provided with .an opening registering with the said tubular punch and a spout extending inclinedly upwardly from the secondary plate from a point adjacent the opening in the said secondary plate. 1

3. A can perforator and holder comprising a primary plate having a can engaging hook at one end and a depending inwardly disposed spring member at its opposite end for engaging a can, a secondary plate swingably attached at one end to the primary plate, said primary plate being provided with an opening therein, said secondary plate being provided with a tubular punch thereon adapted to be disposed through the opening in the primary plate to pierce the top of a can engaged by the primary plate, said inwardly disposed spring member being bent backwardly and then downwardly to provide a handle whereby a car:1 on which the perforatoris applied can be car- Th 4. A can perforator and holder comprising a primary plate having a can engaging hook at one end and a depending inwardly disposed spring member at its opposite end for engaging a can, 45
