NON DETACHABLE PULL TOP CAN
Abstract
A rimmed can has a top with scoring and folding lines on it. A
band is beneath the scored section and is attached to a pull ring.
A pair of extruded frictional clamps are on the pull ring so that
when the top is pulled, the tab-shaped ruptured section is folded
back along the fold line and the clamps engage the rim. Thus the
tab is secured to the can.

Claims
Having herein described the invention, what is claimed as new
is:
1. A container comprising a sidewall having a rim, a top section
extending across said sidewall and having a scoring and a fold, a
gripable means secured to said top section for rupturing said top
section along said scoring and for folding the resultant ruptured
section along said fold towards said rim, and means mounted on said
gripable means for frictionally engaging said rim said fold
extending parallel to a tangent to said rim at the point of
engagement said engaging means comprising a pair of extruded
projections for clamping to both sides of said rim, said
projections extending parallel to said rim when said ruptured
section is fully folded towards said rim whereby said ruptured
section can be folded back and secured to said rim without twisting
while remaining attached to said container.
2. A container as claimed in claim 1 wherein said gripable means
comprises a band secured at one end to said rim and at another end
to said top.
3. A container as claimed in claim 1 wherein said gripable means
comprises a pull ring.
4. A container as claimed in claim 1 wherein said scoring has a
greater dimension near said rim than further away, whereby
dispensing is easier.
5. A container as claimed in claim 1 wherein all of said recited
elements comprise aluminum.
6. A container as claimed in claim 2 further comprising a rivot
means for securing said band to said top section.
7. A container as claimed in claim 2 wherein said band comprises a
fold coinciding with said top section fold.
8. A container as claimed in claim 2 wherein said sidewall is
circular in cross-section and said band is slightly longer than the
radius of said sidewall.
Description
The present invention relates to pull top cans, and more
particularly, to cans having non-detachable pull tops.
Present pull top cans have a top section that either completely
separates from the remainder of the can after opening, or is merely
bent back along a fold line, and therefore can easily work lose
from the can. This results in increased litter, and in tab shaped
sections that can be used as "slugs" in devices such as parking
meters. Because of this, some states have banned detachable pull
top cans.
One solution to these problems is to use a non-pull top can, but
this requires an external can opener, such as a "church key."
It is therefore an object of the present invention to have a
non-detachable pull top can.
It is another object to have a can where the ruptured tab section
cannot be used as a coin substitute.
It is still another object to have a can that does not require an
external opening device.
In brief, these and other objects are achieved by having a rimmed
container with a gripable means for rupturing a top section, and
means on said gripable means for engaging the rim and securing the
ruptured tab to the container.
Other objects, features, and advantages will become apparent from
the description when taken in conjunction with the drawings in
which:
FIG. 1 is a top view of a closed can.
FIG. 2 is a cross section taken along the line 2 -- 2 of FIG.
1.
FIG. 3 is a top view of an open can.
FIG. 4 is a cross section taken along the line 4 -- 4 of FIG.
3.
FIG. 5 is a side view.
In FIGS. 1 and 2 there is shown a can 10, which can be made of
aluminum, having a rim 12, and a top 14. A rupturable score 16 is
on top 14 with a wider portion nearest the rim 12 for easy
dispensing. A fold 18 is provided to enable the tabular ruptured
section 19 to be folded back. A band 20, which also has a fold
coinciding with fold 18, extends from and is secured to, one side
of rim 12. At slightly more than one half of the radius of top 14,
band 20 is to be joined to tab 19 by rivot 22. A pull ring 24 is
secured to top 14 and band 20 by rivot 22. Extruded clamps 26, 28
are on pull ring 24, which also has a finger receiving hole 30.
In operation, the user inserts his finger into hole 30 and first
pulls ring 24 away from the side of the can and then up. This
causes score 16 to rupture and tab 19 and band 20 to move away from
top 14 by pivoting along their fold 18. Then a simple wrist or
finger action causes clamps 26 and 28 to frictionally engage rim 12
as shown in FIGS. 3, 4, and 5 so as to prevent tab 19 from working
lost from can 10, and also to keep tab 19 from getting in the way
of the mouth of the user. It will be seen that at all times the tab
19 and band 20 are attached to can 10.
While the present invention has been described with respect to only
one embodiment, many others are possible without departing from the
spirit and scope of it.
