follows:-
The invention relates to thin metal packages for containing perishable goods and
protecting them from the action of air, water, and other fluids. The object is to

COMPLETE SPECIFICATION.
Improvements in and in Apparatus for Opening Fluid-tight
Packages.
I WILLIAM HENRY POWELL of 40 Elm Road, Seaforth in the County of
Lancaster Accountant, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The invention relates to thin metal packages for containing perishable goods and
protecting them from the action of air water and other fluids. The object is to
enable such packages to be cheaply made and readily and inexpensively opened.
The invention consists essentially in constructing the said packages with a weak
line of connection, and in combining therewith a push piece devised so as to divide
the said package into two parts through the said weak line of connection.
The accompanying perspective view Fig. 1 represents a fluid tight package and
opener constructed in accordance with my invention, whilst Fig. 2 is a transverse
section of the end of the package where the opening is effected. The body a of
the package, and the bottom are of metal soldered or united together so as to be
fluid tight, in any usual way. b is the top of the package made of thin metal
soldered or otherwise united fluid tight to the body a. c is a groove in the thin
metal top b, close to the edge of the body and making a weak line of connection
between the parts. The said groove also serves as a guide for the cutter. d is a
recess in the top of the package in which the cutter rests. e is a cap which fits
over the cutter and top so as to prevent the cutter from being lost and to
strengthen that end of the package. f is the cutter which consists of vee shaped
recessed cutting edges f¹ connected by a stem to a head f³, one of the points of
the cutter is pressed through the groove and the said cutter is pushed along the
groove the recess in the cutter keeping it within the said groove.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
⚫claim is :-
First. The combination of the package a having a weak line of connection c with
a push piece or cutter f.
Second. The combination of a package a having a guiding groove c forming a
weak line of connection with a push piece or cutter having recessed and sharpened
-cutting edges.
