PROVISIONAL SPECIFICATION.
Improvements in Caps and Stoppers for Bottles, Jars, and other
Vessels.
I, ASTOR BOISSELIER Merchant and Agent of 1 Creechurch Lane and
86A Leadenhall Street in the City of Loudon do hereby declare the nature of
this invention to be as follows:-
My invention consists essentially of an improved form of cap or stopper for
bottles, jars, or other similar vessels containing syrups or other thick and sticky
substauces, the object of which is to obviate the inconvenience of extracting such
substances from their containing vessels with a spoon or similar utensil.
I attain my object by securely attaching to the mouth or neck of the bottle or
other vessel, a cap or stopper of metal or other suitable material, in such a manner
that the substance contained in the aforesaid vessel, can be poured out and cut off
at any desired moment, cleanly and efficiently.
I accomplish this by forming, preferably an open cap or rim, or semi-closed
cap or rim to fit the mouth of the containing vessel, provided with a plate or disc
of any suitable material, which in its ordinary position closes the mouth of the
vessel and when drawn back leaves it open. This plate or disc on being closed
quickly, acts as a knife edge on the substance which is being poured out, and cuts
same off sharply and cleanly at any desired moment.

COMPLETE SPECIFICATION.
Improvements in Caps and Stoppers for Bottles, Jars, and other
Vessels.
I ASTOR BOISSELIER Merchant and Agent of 1 Creechurch Lane and
86A Leadenhall Street in the City of London England, 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 consists of an improved form of cap, cover, or stopper for bottles,
jars, tins or other similar vessels containing syrups or other thick and sticky
substances, the object of which is to obviate the inconvenience of extracting such
substances from their containing vessels, with a spoon or similar utensil.
I attain my object by securely attaching to the mouth or neck of the bottle or
other vessel, a cap or stopper of metal or other suitable material, in such a manner
that the substance contained in the aforesaid vessel, can be poured out, and the
flow cleanly and efficiently cut off at any desired moment.
I accomplish my object by forming a semi-closed cap or cover to fit the mouth
of the containing vessel, provided with a plate or disc of any suitable material,
which in its ordinary position closes the mouth of the vessel and when drawn back
leaves it open. This plate or disc on being closed quickly, acts as a knife edge on
the substance which is being poured out, and cuts same off sharply and cleanly at
an desired moment.

page_text: Figure I is a plan drawing of my improved contrivance, provided with an
aperture B and two grooves C. C. into which fits the slide D furnished on the
upper surface with a small knob or projection E. This slide D is adjusted so as to
slide up and down between the two grooves C. C., over aperture B, covering same
when pushed down and exposing same when drawn up. This said slide D may be
kept in position and prevented from sliding out entirely, by any convenient means,
such for example as shown at F. F. in Figure II, where the slide D moves between
two layers of metal, the upper one being slotted at G, to allow the knob or
projection E (slide D) to pass through it and to act as a check to the same.
Figure II shows the slide D partly closing aperture B, dotted lines being used
to show the position of said slide D when inserted.
In Figure III the slide D is so constructed as to draw out beyond the rim of
the cap. This slide is made longer than in Figures I and II and the knob E in
this case, may project on both the upper and lower surfaces, so that the lower
projection may be utilized as a check to prevent the slide D being drawn entirely
away from the cap.
Figure IV is a plan drawing of another adaptation of the same principle. In
this case the rotating slide A instead of moving upwards and downwards over
aperture B as in Figures I, II and III, moves over said aperture from right to
left or left to right, working on a pivot in the centre of the cap. At that part of
the cap which actually covers the opening or mouth of the vessel, that is to say
the top part only as shown in Figure IV, the said cap is constructed with two
layers of metal, one layer being just above the other, with a slight space in between
The upper layer has a slot G, and a small circular opening H in the
the two.
centre.
The rotating slide A (Figure IV) which is provided at both E and D with
a small knob or projection, is placed between the two above named layers of metal
in such a manner that the knob E passes through the slot G, and the knob D
through the small circular opening H.
By sliding knob E along slot G either from right to left or vice versa, aperture B
becomes either covered or exposed by the slide A rotating on the pivot formed by
knob D at H.
Figure V is a perspective view of the top part of a bottle fitted with the first
form of my improved cap or cover.
These caps may be made of metal or any other suitable material.
The action of my contrivance is as follows: The slide D being drawn back as
shown in Figures II and III or the rotating slide A. as in Figure IV the liquid is
allowed to pour out through aperture B by tilting the bottle, and at any instant
the flow of liquid can be checked and cleanly cut off by closing the said
slides D or A.
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;
An improved cap, stopper, or cover with attachments as herein described, to be
fitted to vessels containing viseid liquids, by means of which any required quantity 4
of such viscid liquids can be poured out of the containing vessel, and the flow
cleanly and instantly cut off, thus avoiding the well known inconvenience usually
experienced in handling the said viscid liquids.
