COMPLETE SPECIFICATION.
A New or Improved Seal for Hermetically Closing Bags, Cases, Boxes,
or Chests Containing Articles of Food or the like, Signals, Life
Saving Appliances, Compasses, and other Instruments used on
Board Ship.
I, LOUIS DEZAUNAY, Clerk, of Sainte-Adresse, Dep. (Seine-Inferieure), France,
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 follow-
ing statement:-
The sealing of bags, cases, boxes, chests or caskets containing articles of food
or the like safety apparatus, danger signals, life saving appliances, mathematical
instruments, compasses, and all other similar instruments such as are used on
board ship in order to find the necessary bearings and to steer, should be hermeti-
cally sealed and remain sea water proof. Such seals should be readily broken
without requiring any sharp instrument or edged tools which may be missing
when wanted or may not be obtained in time.
In the accompanying drawing Fig. 1 is a perspective view of a closed box fitied
with a seal constructed according to the present invention and Fig. 2 is a similar
view showing the seal partially broken.
To avoid the use of a special tool and yet to allow of the seal being hermeti-
cally closed again after having been broken, I have devised a seal consisting of an
india rubber band or strip or of a band or strip A of any other suitable water
tight fabric such as gutta percha in sheets or of ordinary fabric coated with size
or other adhesive material, such as india rubber gutta percha, marine glue,
Chatterton's compound, pitch, wax, and the like, or of solder or water-tight varnish
of any kind. Under the band or strip intended to be glued, I previously pass a
wire B fixed at a point opposite the opening; at the end of this wire I fix a ring b
on a suitable handle. When the impermeable band or strip A covers the joint,
and it is required to open the case or the casket, the ring b or handle is pulled, so
that the wire B may cut through the band or strip A as clean as any edged tool.
The side which is not cut through serves as a hinge and the box, case or casket
may be closed again, so that the impermeable band or strip may again prevent the
ingress of water.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
―
The improved seal above described for bags, boxes caskets, or cases, containing
safety apparatus, life saving appliances, articles of food, preserves and the like,
consisting of a hermetical joint comprising a band or strip of india rubber or
any suitable impermeable fabric such as gutta percha in sheets or sheets of
ordinary fabric coated with glue, paste, india rubber, gutter percha, marine glue,
Chatterton's compound, pitch, wax or other water tight glue, solder or varnish,

page_text: the breaking of such seal being instantaneously effected by means of a wire cut-
ting through the band or strip or joint without the use of any edged tool, sub-
stantially as herein described.
