CAN PIERCER AND HOLDER Filed Sept. 10, 1956 FIG. 2
' INVENTOR Mdrdus F. Charlton CAN PIERCER AND HOLDER Marcus F. Charlton, Stoutrville, Ontario, Canada Application September 10, 1956, Serial No. 608,723
Claims. (Cl. 30-123) This invention relates to can opening devices.
It is an object of the present invention to provide a can piercer and holder which is particularly adapted for evaporated milk cans although applicable to other types.
It is another object of the present invention to provide a can piercer and holder of the above type which not only cuts the necessary holes in the top of the sealed can but instantly converts the can itself into a pitcher ready for use instantaneously.
Other objects of the invention are to provide a can piercer and holder bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efiicient in operation and use.
For other objects and for a better understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:
Figure 1 is a perspective view of a preferred embodiment of the present invention showing the can piercing member in the inoperative position to be used as a handle;
Fig. 2 is an enlarged side elevational view thereof shown partly in section and illustrating in phantom the movement of the can piercing member; and
Fig. 3 is a top plan view of the can after the holes have been sheared therein.
Referring now more in detail to the drawing, represents a ring-shaped base member connected to an upper cylindrical ring 11 by means of the vertical spacers 12 and 13, substantially as illustrated.
The spacer 13 extends upwardly above the upper edge of the ring 11 (Fig. 2) and is integrally formed at its lower end with the supporting portion 14 bent outwardly at right angles thereto. The ring 11 is secured to the spacers 12 and 13 by means of the rivets 15 or other suitable fastening means while the ring 10 is welded to the lower ends of the elements 12 and 13 as at 16.
The vertical support 13 at the upper end thereof is integrally formed at right angles thereto with the laterally spaced segment-shaped bearing members 17 which are connected by the hinge rivet 18. A V-shaped handle 19 (of U-shaped cross section for straightening purposes) is provided and is integrally formed at its upper end with the laterally spaced lugs 20 having laterally aligned openings which receive therethrough the hinge rivet 18 whereby to rotatably mount the handle thereat for a purpose which will hereinafter become clear. The lower end of the handle 19 is provided with a rectangular cutout 21 while the upper end thereof is integrally formed with the flat curved extension 22 which extends upwardly and inwardly and terminates in a reduced portion 23 which in turn is integrally formed with a downwardly bent prong or piercing member 24, substantially as illustrated.
A leaf spring 25 is secured to the upper surface of the base portion 14 by the fastening means 26 and is integrally formed at its outer end with a reduced hookshaped catch 27 adapted to normally engage the portion of the handle 19 above the cutout 21 and to retain the nited States Patent 0 same inthe inoperative position of Figs. 1 and 2 and to serve as a handle Upon pressing the catch 27 downwardly, however, the handle may be rotated in a counterclockwise direction, as shown in phantom in Fig. 2.
A pair of vertically extending leaf springs 28 are welded at their lower ends to the ring 10 and are integrally formed at their upper ends with the inwardly curved portions 29 which firmly engage the can of evaporated or condensed milk 30 which is positioned within the ring 11 and rests on the base ring 10.
In operation, the can 30 is taken and placed in the open top of the ring 11 and pushed downwardly to the bottom ring 10, the upper tips 29 of the leaf springs 28 engaging the sides of the can and holding it firm. Then the catch 27 is pressed downwardly to release the handle 19. The handle is then rotated towards a horizontal position in a counterclockwise direction, simultaneously projecting the cutting point or prong 24 downwardly and into the can top, as shown in phantom in Fig. 2, to pierce the can with a triangular opening 31 having one of its apexes disposed uppermost. Next, the handle 19 is pushed back to its original position to be engaged by the catch 27 to retract the cutting point 24. The can is then rotated 180 degrees in the holder with the other hand and a second opening for air is similarly provided by following the above steps, this opening being indicated at 32 (Fig. 3). The handle is again pushed back to its original position until engaged by the catch 27 to provide a convenient pitcher for dispensing milk or the like. The above procedure can be completed in a matter of seconds and the empty cans are easily ejected. The invention can, of course, be adapted for manufacture in a variety of materials.
It should be apparent that the device is simple and foolproof and anyone from housewife to coffee bar attendant can operate it with a minimum of time and effort. One of the advantages of the device is that the apex of the openings 31 and 32 is started near the periphery of the can 30 and the cut metal is rolled up ahead of the advancing cutter and thus is out of the path of the pouring liquid, enabling one to evacuate all of the contents of the can (Fig. 3) when employing the lowermost opening 32. Thus, the flange or rolled up metal 34 is above the opening 32 and will not interfere with the flow of the liquid.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
What I claim as new and desire to protect by Letters Patent of the United States is:
l. A can piercer and holder comprising a hollow member adapted to support therewithin a can, a pair of laterally spaced bearing members at the upper end of said holder at one side thereof, a horizontal supporting portion below said bearing members, a handle member pivotally mounted intermediate said bearing members with the lower end thereof resting on the outer end of said horizontal supporting portion, spring means carried by said horizontal supporting member for retaining the lower end of said handle in engagement with said supporting portion whereby to serve as a pitcher handle when the can is within said holder but to permit the release of the same, and can piercing means at the upper end of said handle adapted to shear an opening in the top of the can, said can piercing means rolling up the metal in front of the same so as not to interfere with the flow through the subsequent opening provided thereby.

3. A can piercer and holder according to claim 2, one of said oppositelydisposed vertical supports extending upwardly above the upper edge of said hollow cylindrical ring and being integrally formed at right angles herein with said laterally spaced bearing members, said horizontal support being integrally formed at the lower end of said vertical support.
4. A can piercer and holder according to claim 3, said spring means comprising the lower end of said handle having an upwardly extending cutout, and a leaf spring secured to the upper surface of said horizontal support'and integrally formed with outwardly extending reduced hook shaped member adapted to normally engage the portion of said handle above said opening therein and to release the same upon being depressed downwardly and to pass through said handle opening.
5. A can piercer and holder according to claim 4, said piercing means comprising the upper end of said handle being integrally formed with an inwardly and upwardly curved portion integrallyforn ed at its upper end with a reduced portion following the curvature thereof, said reduced portion being integrally formed with a downwardly bent triangular prong adapted to pierce the top of the can near the periphery upon upward movement of said handle and to roll up the opening; metal before the same so as not to interfere with the flow of liquid.
