PROVISIONAL SPECIFICATION.
An Improved Construction of Canister or Vessel for Holding Tea,
Coffee, and other substances.
1, CLEMENT SANKEY BEST GARDNER, of Neath, in the County of Glamorgan,
Manager of Works, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved construction of canister or vessel for
holding tea, coffee, and other substances liable to deterioration by exposure to the
air, and it has for object the separation of a portion of the contents of the canister
from the bulk so that this portion may be delivered for use without exposing the
remainder to the air.
I attain my object by forming the neck of my canister double, one part revolving
on, in, or around the other, and the bottom of the revolving part being of a section
corresponding with the section of the orifice or orifices left for the passage of the
contents from the body into the neck of the vessel, say one half of the diameter of
the neck; I fit the revolving neck with a stop-rivet to prevent its being turned too
far either in opening or in closing the orifice or orifices, and I provide the cap or
cover with a bayonet joint in the horizontal slot of which a fastening pin on the
revolving neck will be held preventing the cap being accidentally withdrawn when
the orifice is open and the canister in a reversed position; I may however use other
suitable means for arresting the revolution of the neck and otherwise secure the outer
cap so that it cannot be accidentally removed without first closing communication
between the body and the neck of the canister.
When it is required to take from a canister thus inade, the quantity of its contents,
say tea, required for use, the canister may be held upright and the cap or cover
turned until it meets a stop exposing the mouth or orifice of the canister. The
canister must then be reversed, thereby enabling the ten to fill the empty space in
the neck; the cap is then turned in the opposite direction thereby closing the orifice
or orifices and the canister is replaced in an upright position before removing the
cap. The cap may then be withdrawn leaving the neck filled with tea, without
any exposure of the bulk to the air.
I
may make
my improved canister or vessel of tin or other suitable metal or
material, and although I now give preference to a cylindrical form. of neck and
cover I may make my canister and its neck of any form which I may find inore
convenient.

I CLEMENT SANKEY BEST GARDNER, of Neath in the County of Glamorgan,
Manager of Works, 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 :-
This invention relates to an improved construction of canister or vessel for
holding tea, coffee and other substances liable to deterioration by exposure to the
TD 037

page_text: being accidentally withdrawn when the passage from body to neck is open and the
canister in a reversed position.
I may vary the above details of construction while retaining the main feature of
my invention and I may make my improved canister or vessel of tin or other
suitable metal or material and I may make the body and neck of any shape which
I may find desirable.
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 :-
1. A canister or vessel having a double neck one part revolving on, in or around
the other and arranged to operate a revolving plate or diaphragm, in combination
with a fixed plate or diaphragm, to open an orifice or orifices for the passage of the
contents from the body into the neck of the canister or vessel and to close the same
to effect the delivery of a portion of the contents without exposing the bulk to the
air, substantially as described.
2. In a canister or vessel having a double neck and fixed and revolving
diaphragms as described, the arrangement for turning and arresting the revolving
diaphragm consisting of the projection on the neck B, the projection or
recess g on the cap G, the slots on the fixed plate or diaphragm and the stop F
on the plate or diaphragm D, all substantially as herein before described and
illustrated Figures 1 to 4 of the accompanying drawing.
3. In a canister or vessel having a double neck and fixed and revolving
diaphragms as described, the use of bayonet joints (H, I) for securing the top or
cover from accidental removal during the revolution of the diaphragm, substantially
as hereinbefore described and illustrated Figures 5 and 6 of the accompanying
drawing.
