PROVISIONAL SPECIFICATION.
Improvements in and Means for Closing and Fastening Bags, Boxes,
Packing Cases, and the like.
I MARCUS EYCK of Freystadt in the Province of Westprussen German Empire
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide an improved means for closing and
fastening bags boxes, canisters sample and packing cases and the like, whereby the
contents of such bags boxes or like receptacles may be secured therein without
damage to the receptacle which is thus enabled to be used many times.
Now according to this invention I form the box bag or case to be closed by my
method with two flaps at the mouth formed by cutting down for about an inch at
each corner the other two sides of the bag box or casc are made slightly tapered
at the mouth so as to allow the flaps to close in somewhat. To these flaps I attach
pieces of metal or other suitable material to which are secured the ends of a spiral
spring which forces the flaps outwards.
I provide also a lid or cover to the box bag or case which is wider at the top
than at the bottom.
To close the bag or box the flaps are pressed towards each other and the lid
slipped on when the pressure is removed from the flaps the spring forces them
outwards and holds the lid firmly and closes the mouth of the bag box or case.
For further security I may in some cases attach catches formed of bent wire
or other suitable substance to the above mentioned pieces of metal which pass
through slots in the lid or cover so that when rotated a quarter of a turn the said
catches secure the lid from accidental removal.

COMPLETE SPECIFICATION.
Improvements in and Means for Closing and Fastening Bags, Boxes,
Packing Cases, and the like.
1, MARCUS EYCK, of Freystadt, in the Province of Westprussen, German
Empire, 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 object of this invention is to provide an improved means for closing and
fastening bags. boxes, canisters sample and packing cases and the like whereby the
contents of such bags boxes or like receptacles may be secured therein without
damage to the receptacle which is thus enabled to be used many times.
Now according to this invention I form the box, bag, or case to be closed by my
method with two flaps at the mouth formed by cutting down for about an inch at
each corner the other two sides of the bag, box, or case are made slightly tapered
at the mouth so as to allow the flaps to close in somewhat.
To these flaps I attach pieces of metal or other suitable material to which are
secured the ends of a spiral spring which forces the flaps outwards.
1 provide also a lid or cover to the box bag or case which is wider at the top
than at the bottom.
To close the bag or box the flaps are pressed towards each other and the lid
slipped on when the pressure is removed from the flaps the spring forces then
outwards and holds the lid firmly and closes the mouth of the bag box or case,

page_text: For further security I may in some cases attach catches formed of bent wire or
other suitable substance to the above mentioned pieces of metal which pass through
slots in the lid or cover so that when rotated a quarter of a turn the said catches
secure the lid from accidental removal.
And in order that my said invention may be fully understood, I will proceed to
explain the same with reference to the accompanying sheet of drawings in
which
Figure 1 shews elevation of a box or canister and lid constructed according to
this invention.
Figure 2 is section of same.
Figures 34 and 5 shew modifications of the same invention.
The same letters denote the same parts in all the figures.
a is the box, case or canister, the sides of which a are cut tapered at the open
end as shewn leaping flaps on the longer sides thereof which flaps are normally
pressed apart by the spiral springs c, d is the lid made wider at the top than at the
bottom as shewn at Figure 2.
I provide also fasteners or catches e which pass through slots in the lid and when
turned at right angles thereto prevent the lid from being accidentally displaced.
C
When the lid d is to be placed on the box or case a the flaps 6 are pressed
together, the lid d is placed on the box or case when the pressure of the spring
forces the flaps outwards and presses them against the inside of the lid & securing
it firmly to the box. For extra security the catches e are turned till they assume
the position shewn in dotted lines Figure 1 thus preventing the lid from being
accidentally displaced in transport.
In some cases I may form depressions or corrugations and in the box a and
lid d as shewn in Figure 5 and place an indiarubber ring or band in the corrugation
in the box which when the lid d is in position will form an air and water tight joint
between the canister or box and the lid. Or the box or canister and the lid may
be both corrugated with the concave side of the corrugation outwards as shown
at Figure 5 in which case the fasteners e may be dispensed with and an india-
rubber band placed in the corrugation outside the lid holding the same firmly to
the box or canister.
If the box is made of lead, cardboard or other soft material I attach pieces of
metal to the flaps to strengthen the same and to these pieces of metal I fasten
the springs c and catches e.
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 I
claim is :--
I. In a means for closing and fastening bags, boxes, packing cases and the like
the combination of flaps forming part of the sides of the bag box or case normally.
pressed outwards by springs c with a tapering lid d, substantially as and for the
purpose stated.
II. In means for closing and fastening bags, boxes, packing cases and the like
the combination of a tapering lid d, having slots therein with the catches e
attached to flaps on the case, box, or bag substantially as described and for the
purpose stated.
III. In a means for closing and fastening, bags, boxes, packing cases and the
like, the strengthening pieces substantially as described and shewn.
IV. In a means for closing and fastening bags, boxes, packing cases and the
like corrugating the box, case, or bag and the lid substantially as specified and for
the purpose stated.
