A further object of the invention is to provide a sealing
strip guide which is provided with planar outer faces so
that any force applied thereon will naturally tend to press
the guide against the can and maintain it on the can.
Still further objects and features of the present inven
tion reside in the provision of a sealing strip guide that is
simple in construction, capable of being manufactured
out of any readily available materials such as synthetic
plastics, metal, or the like, and which may be inexpen
sively formed of an integral body thereby allowing Wide
use and distribution.
These, together with the various ancillary objects and
features of the invention which will become apparent as
adapted to be utilized in conjunction with the key 32.
The guide 30 includes a body 42 which is provided with
outwardly converging or tapered outer faces 34 and 36
shaping the body into a substantially triangular member

A horizontally extending groove 50 is formed in the
body 42 and is slightly larger than the sealing strip 18 in

is further provided with a vertically extending slot 54
which extends therein normal to the groove 50 and ten

shown in FIG. 1, the guide 30 is arranged so that the
projection 66 is hooked over the rim 16 with the key en

groove 50 with the sealing strip 18. As the sealing strip
18 is wound around the key 32, the sea-ling strip will be
prevented from vertical displacement. After a ‘number of

Further, if the guide 30 is held, the surfaces 44 and 46 are
so arranged ‘that forces on the guide will generally be‘

A latitude of modi?cation, change and substitution is
intended in the foregoing disclosure and in some instances
some features'of the invention will be employed without a
corresponding use of other features. Accordingly it is
appropriate that the appended claims be construed broadly
