panying drawing and speci?cally pointed out in
the appended claims.
In describing the invention in detail, reference
will be had to the accompanying drawing where
in like characters denote like or corresponding
parts throughout the several views, and in which:
Figure 1 is a fragmentary sectional view taken
35 through one form of my invention, applied to a
can, after an opening has been punched therein,
to act as a sealing means for the opening.
Figure 2 is a view of a modi?ed form.
Figure 3 is a top plan view of the form as shown
40 in Figure 2.
Figure 4 is a longitudinal sectional view taken
through the form as shown in Figure 1.
Figure 5 is a bottom plan view of the form
shown in Figures 1 and 4.
Referring to the drawing in detail, it will be
noted that the form of the invention as disclosed
in Figures 1, 4 and 5 includes an elongated body
I having extending through the ends thereof the
shank 2 of the punching members that have
00 formed on the outer ends thereof conical heads 3
provided with penetrating points 4 at their outer
ends, while the inner end portions are provided
with channel grooves surrounding the shanks, as
best shown in Figure 1, for a purpose which will
55 be presently described.
In Figures 2 and 3 I have illustrated individual '
punching members that are used separate and
distinct from each other, or in other words not 30
in connected pairs, as shown in the form of Fig
ures l, 4 and 5, and the only difference between
the form of Figures 2 and 3 and that of the other
?gures, is the fact that a disk body I0 is pro
vided therefor ‘and which has the shank extend- 35
ing therethrough and held thereon by a nut in
the same manner as best shown in Figure 1, the
nut being countersunk in the body H), as will be
In the form of Figures 1, 4 and 5, it will be ob- 40
vious that the openings can be punched simul
taneously in the top of the can, merely by applying
the penetrating points of the punching members
thereto, and punching upon the body I, and for
distinction the opening provided by the punching 45
member adjacent to the handle 9 is indicated by
the reference numeral H, and acts as a pouring
opening, while the other opening l2 acts in the
capacity as a vent opening.
The punching members of Figures 2 and 3 are 50
preferably used in pairs, one for providing the .
pouring opening, and the other the vent opening,
so that they can be used as sealing means for the
openings punched thereby, it being obvious that
after the openings have been punched, the punch- 55
ing members can be readily removed and replaced
with respect to the openings, and when disposed
therein, the sleeves 0 seal the same, as clearly
shown in Figures 1 and 4.
It is thought from the foregoing description
that the advantages and novel features of the in
vention will be readily apparent.
It is to be understood that changes may be
made in the construction and in the combination
10 and arrangement of the several parts, provided
that such changes fall within the scope of the ap
pended claims.
What I claim is:
l. A can opening device comprising a body,
punching member secured thereto and including a
shank. a‘ conical punching head formed on the
lower end of the shank and having a groove in the
upper end thereof surrounding the shank, and
tapered pliable means surrounding the shank sub
stantially the entire length thereof and having its
ends countersunk in the body and the groove re
spectively, the lower end of the pliable means be
ing flush with the upper edge of the head and said
pliable means adapted to enter an opening
punched by the head so as to seal ‘the opening.
2. A can opening device comprising a handled
elongated body, a pair of punching members se 5
cured to and depending from the body in paral
lelism with each other, each punching member in
cluding a shank extending through the body and
having a threaded upper end, a nut countersunk
in the body and threaded to the upper end of the
shank, a conical punching head formed on the
lower end of the shank and having a groove in
the upper end thereof and surrounding the shank,
a tapered pliable sleeve surrounding the shank
subst tially the entire length} thereof and having
its en
countersunk in the body and the groove
respectively, the lower end of the sleeve being
?ush with the upper edge of the head and said
sleeve adapted to enter an opening punched by
the head so as to seal the opening.
