PROVISIONAL SPECIFICATION.
Improvements in Boxes applicable for Packing and Preserving
Shrimps, Meat, Fish, or the like.
We, AUGUST PAHL and THÝGO INGWERSEN of the firm of Pahl and Ingwersen
of Husum in the Kingdom of Prussia do hereby declare the nature of this inven-
tion to be as follows:-
Our invention relates to an improved preserve-box or tin-box, especially destined
for preserving shrimps in a fresh state for a considerable length of time and for
transmitting the same to any distance such as to foreign countries.
As is well known, shrimps could not be long preserved hitherto, but used to
become spoiled in the course of a few days, if exposed to the atmosphere, especially
in the warm season. Our improved preserve box enables this much relished dish
to be preserved for a considerable time and to be shipped or transmitted to any
distance, without losing its taste of freshness and without becoming spoiled, squeezed
or broken.
To preserve shrimps in the freshly boiled state and without any other preparation,
than boiling, leaving the little crustaceous animals just as they are, two essential
requirements are to be fulfilled, first, to keep the shrimps immersed in and
surrounded by a suitable preserving fluid within an air-tight box or tin, and
further, to prevent the shrimps, when packed into the box, from shaking or moving
to and fro in the same, otherwise the tender and soft heads and bodies of the shrimps
would be squeezed or torn and come off, and the whole mass would be spoiled by
such disintegration.
These two requirements, the improved box or tin of our invention is destined to
fulfil, and, to obtain the purpose in view, we construct the box or tin of two boxes,
an outer one and an inner one, the former being prepared with a lid for being
soldered, as usual, or hermetically sealed, the other inside box being perforated and
fitted into the outer box in such a manner as to leave a space round about and
above and below the wall, head and bottom of said inner box, and also in such a
manner as to prevent any shifting or shaking of the inner box within the
outer one.
The outside box, preferably of cylindrical shape and of size similar to the usual
tins for preserving ox-tongues, has preferably pressed into its circumference one or
more circular flutes, forming an annular inside boss, or bosses, to provide a bearing
for studs or stays which we form or secure along the outside of the inner box. By
this means the inner box is firmly fitted within the outside box, and any shaking or
shifting is prevented; at the same time, a free space provided and maintained all
around the inside box and between this and the inner surface of the outside box,
the free space equally extends below the bottom and above the top of the
inside box.
The inner, perforated box has an aperture with a suitable door or lid in the top,
to fill the shrimps into said inside box, where they are packed sufficiently tightly
to prevent any shaking and shifting, to prevent frictional wear and tear of the soft
bodies.
The space between the two boxes is completely filled up by the preserving fluid,
which keeps from the preserved mass any atmospheric air, which might have
remained in the outside box, after it had been soldered or sealed, the fluid forming
a tight seal for the contents of the inside box. At the same time, said fluid freely
enters through the many perforations of the inside box and keeps the shrimps in
a state of moisture, without allowing them to float within the fluid.
By this means the shrimps are kept hermetically sealed, surrounded, immersed

page_text: and impregnated by the suitable, preserving fluid, which keeps them in a state of
complete freshness, and they are equally and efficiently prevented from shaking,
floating, shifting and consequently from being torn or squeezed by moving within
the box.
The improved preserve-box or tin keeps the shrimps in a state of perfect
freshness for a considerable length of time and allows of transmitting the same to
any distance.
The box may also be employed for preserving other food of marine or other
production, which requires the same conditions as above described.

COMPLETE SPECIFICATION.
Improvements in Boxes applicable for Packing and Preserving
Shrimps, Meat, Fish, or the like.
We, AUGUST PAHL and THÝGO INGWERSEN of the firm of Pahl & Ingwersen
of Husum in the Kingdom of Prussia, 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:-
Our invention relates to an improved preserve-box or tin-box especially
applicable for preserving shrimps in a fresh state for a considerable length of time
and for transmitting the same to any distance such as to foreign countries.
As is well known, shrimps could not be long preserved hitherto, but used to
become spoiled in the course of a few days, if exposed to the atmosphere, especially
in the warm season.
Our improved preserve-box enables this much relished dish to be preserved for a
considerable length of time and to be shipped or transmitted to any distance,
without losing its taste of freshness and without becoming spoiled, squeezed or
broken.
To preserve shrimps in the freshly boiled state, without any other preparation
than boiling, and leaving the little crustaceous animals just as they are, two essential
requirements are to be fulfilled, first, to keep the shrimps immersed in and surrounded
by a suitable preserving fluid within an air-tight box or tin, and, second, to prevent
the shrimps, when packed up into the box, from shaking or moving to and fro in the
box, otherwise the soft and tender heads and bodies of the shrimps would be
squeezed or torn or broken, and the whole mass would be spoiled by disintegration.
These two requirements, the improved box or tin of our invention is destined to
fulfil, and, to obtain the purpose in view, we construct the box or tin of two separate
boxes, an outer one and an inner one, the outer box being provided with a lid or cover
secured by soldering or other hermetical sealing; the other, inside box being
perforated and fitted into the outer box in such a manner as to leave a suitable space
round about and above and below, between the two boxes; and the said inside box
is so tightly fitted into the outer box, that any shifting or shaking of the inner box
is prevented.
In the accompanying drawings
Figure 1 is an outside view of the improved preserve box.
Figure 2 is a plan or top view of the same, with the cover of the outside box and
the door of the inside box removed.
Figure 3 is a central section drawn to line x-y of Figure 2.
Figure 4 is a side elevation of the inside box, and,
Figure 5 a top view of the door or cover of the inside box.
A, is the outside box, preferably of cylindrical shape and of the size similar to the
usual tins for preserving ox-tongues, but any other shape and size may be employed.
The said box A has pressed into its sides one or more flutes a, forming an inside

page_text: boss or projection, or projections, which serve as a bearing to the studs or stays b
formed or secured on the sides of the inner box B. By means of said bosses and
studs or stays the inner box B is tightly fitted within the outside box and any
shaking or shifting of the inner box is thereby prevented. Instead of the flutes a
and stays b, other lugs, projections and guide-ways may be employed to secure the
same effect of tightly fitting the two boxes one into another. As will be seen from
Figures 3 and 4, the studs or stays b project over the bottom of the inner box B,
and they may equally project from the top, thus leaving a free space between
the two boxes all around and between the two top plates and bottom-plates,
respectively.
The inner, perforated box B has in its top an aperture with a suitable door b¹ or
a cover or lid, which may be loosely fitted, or hinged, to the box; through the said
aperture, the shrimps or other preserves are filled into the inner box B, up to the
top of the same and packed sufficiently tight to prevent any shaking and shifting of
the preserves which would spoil the same by frictional wear and tear
disintegration.
or
The space between the two boxes is completely filled up by a suitable preserving
fluid which keeps the preserved mass free from any contact of atmospheric air,
the fluid forming a tight seal all around the inside box and its contents.
The fluid also freely enters through the many perforations of the inside box and
serves to keep the preserves in a state of moisture, without, however, allowing the
preserves to float within the fluid.
By this means, the shrimps or other preserves are kept hermetically sealed,
surrounded, immersed in and impregnated by the preserving fluid, which keeps them
in a state of complete freshness, and as the contents of the inner box are firmly packed
therein, no shaking, floating or shifting, and consequently no wear and tear and
disintegration will occur during transmission.
Instead of using an inside box B of perforated sheet metal, a wire or wire gauze
box, or a wicker-, cane- or reed-box, which may be covered with a suitable fabric
or cloth, might be used with the same result.
The improved preserve-box may be equally employed for packing and preserving
fish, meat, fruit and the like, which require the same conditions as before
described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A preserve box, consisting of an outside box A, capable of being hermetically
sealed, and a permeable inside box B so arranged in the box A, as to leave a space
between the two boxes, suitable means being provided to prevent shifting or
shaking of the inner box, substantially as described.
2. In a preserve box, the combination, with an outside box A, having flutes or
inside projections, a, of an inside perforated or permeable box B, having an aperture
in the top and stays b, at the sides to secure an open space between the boxes and
prevent shifting, substantially as described.
3. A preserve box, consisting of an outside box or tin A capable of being
hermetically closed, and an inside box B of perforated sheet-metal, or other
permeable material, to hold the contents, the space between the two boxes being
filled with a suitable fluid, substantially as described.
