COMPLETE SPECIFICATION.
Improved Mode of Packing and Conserving Provisions.
I, JOHN COLEMAN BLANCH FLOWER, of 95, 96 and 97, King Street, Great
Yarmouth, in the County of Norfolk, Preserved Provision Manufacturer, 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:-
My invention relates to the packing or putting up and conserving of potted meats,
fish, game, and such like preserved provisions with the object of enabling same to be
kept indefinitely in a sound state of preservation and to ensure that when required
for use not only shall the provisions be good and edible but their enclosing jars
or receptacles shall also be clean and sweet. Experience has shown that provi-
sions enclosed in ordinary china, earthenware, stoneware, glass, or like hard clean
receptacles will not keep sound in hot climates, and the use of tins in contact
with the goods is objectionable and has sometimes caused poisonous results; the
provisions must therefore be kept from contact with tin or other metallic substance
and also from rubber washers and all other substances which are corrodible, offen-
sive to taste or smell, or perishable, and for long keeping good vacuum must be
secured and maintained.
According to my invention I use a jar, lining, or receptacle for the provisions
made of glass, china, earthenware, stoneware, terra cotta, porcelain, majolica,
Doulton ware, Wedgwood, alabaster, or like hard clean material in combination with
an outer hermetically closed tin casing, and in practice I proceed as follows.
I place the provisions in the said jar or receptacle and apply a suitable stopper
which is not completely airtight, next I place this closed receptacle in the
enclosing tin case and solder on the lid thereof. Then I effect the cooking process,
the heat serving to expand and drive off all or practically all air and vapours
from the provisions into the tin. 1 then pierce a small hole in the tin and liberate
all such hot compressed air and vapours and immediately close up the said hole,
and by the subsequent cooling process a sufficiently complete vacuum is established
in both jar and hermetically closed tin, and the process is complete. Provisions
thus hermetically sealed in a tin containing their actual receptacle will keep
indefinitely, and when required for use the tin is opened in the usual way and
may be thrown aside, the jar containing the provisions having maintained its original
state.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The improved mode of packing or putting up and conserving provisions
substantially as and for the purpose above set forth.
2. For packing and conserving provisions and enabling same to be kept sound
indefinitely the use of a suitably stoppered receptacle for the provisions made. of
material such as above specified, in combination with a tin casing enclosing same and
hermetically closed, the process being conducted in the manner above indicated.
