BACARIONAL DELICATION
"
I CHARLES CHESWRIGHT of Leith Villa Parkhurst Road Holloway in the County
of Middlesex Manufacturer do hereby declare the nature of said invention for
"A MODE OR METHOD OF AND MEANS FOR CLOSING AND PREVENTING THE
FRAUDULENT REFILLING OF POTS JARS OR OTHER WIDE MOUTHED VESSELS
(partly communicated to me from abroad by Henry Cheswright Capsule Manu-
facturer of Floirac Bordeaux in the Republic of France and partly my own
invention) to be as follows:-
This Invention relates to the hermetical closing and prevention of the fraudulent
refilling of pots jars and other wide mouthed vessels such for example as are used
for containing jains marmalade honey preserved fruits and other perishable goods
and consists in the combination of a screw thread formed outside the neck of the
vessel a shoulder or seat at the top of the screwed portion containing a packing
ring of rubber or other suitable material which may be kept in position either by
letting it into an annular recess or groove in the seat or by an inner concentric
projecting lip round the actual mouth of the vessel a loose lid or cover of glass or
other suitable material provided with a lip which is pressed upon the said packing
ring, a screwed collar (fitting the screwed neck) of stout metal or other matorial
not liable to shrink or crack said collar having one or more milled edges formed
round it exteriorly and an inner projecting flange formed at its upper end between
which flange and the top of the loose lid or cover is interposed a cushion of felt
rubber or other yielding or compressible material, and lastly a Trade Mark
screwed capsule either closed at the top or having openings to show the glass
beneath, the said capsule being hermetically closed round the loose lid or cover as
well as round the screwed portion of the neck of the vessel and made fast thereto
by cement or otherwise so that it not only assists in conjunction with the screwed
collar in maintaining the closure of the vessel air tight but also prevents the
possibility of fraudulent refilling by being necessarily destroyed in the act of
opening the vessel. The pressure exerted upon the loose lid by the downward
screwing of the collar produces an uniform pressure of the tip of the said lid onto
the rubber packing of such force as in conjunction with the screwed capsule to
ensure the hermetical closure of the vessel.

COMPLETE SPECIFICATION.
"
I, CHARLES CHESWRIGHT of Leith Villa Parkhurst Road Holloway in the County
of Middlesex, Manufacturer do hereby declare the nature of my said invention
for "A MODE OR METHOD OF AND MEANS FOR CLOSING AND PREVENTING THE
FRAUDULENT REFILLING OF POTS JARS OR OTHER WIDE MOUTHED VESSELS
(partly communicated to me from abroad by Henry Cheswright Capsule Manu-
facturer of Floirac, Bordeaux in the Republic of France and partly my own
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 the hermetical closing and prevention of the fraudulent
refilling of pots jars and other wide mouthed vessels such for example as are used
for containing jams, marmalade, honey, preserved fruits and other perishable goods
and consists in the combination of a screw thread formed outside the neck of the
vessel a shoulder or seat at the top of the screwed portion containing a packing
ring of rubber or other suitable material which may be kept in position either by
letting it into an annular recess or groove in the seat or by an inner concentric
projecting lip round the actual mouth of the vessel-a loose lid or cover of glass or
other suitable material provided with a lip which is pressed down upon the said
packing ring a trade mark screwed capsule either closed at the top or having
openings therein to show the glass lid or cover beneath it the sides of the said
capsule being hermetically closed round the said lid or cover as well as round the
screwed portion of the neck of the vessel and made fast thereto by cement or
otherwise so that it not only assists in maintaining the closure of the vessel air
tight, by enveloping it in impermeable material, but also prevents the possibility
of fraudulent refilling by being necessarily destroyed before the removal of the lid
for the opening of the vessel can be effected-and lastly a screwed cap or collar of
stout metal or other material not liable to shrink or crack which is screwed over
the soft metal capsule on the screwed portion of the vessel, said cap or collar having
for convenience of manipulation one or more milled edges formed round its exterior.
When in the form of an open collar an inner projecting flange is formed round the
upper edge thereof and between this flange or the closed top of the stout metal cap
as the case may be and the top of the soft metal capsule covering the loose lid or
cover there may be interposed a ring or disc of soft rubber felt or other compressible
material presenting a yielding bed or surface to the rigid cap or collar when being
screwed home. The pressure exerted upon the loose lid by the downward screwing
of the rigid cap or collar produces an uniform pressure of the lip of the said lid
onto the rubber packing round the lip of the vessel of sufficient force to effect in
conjunction with the screwed capsule the hermetical closure of the vessel.
Figure 1 of the accompanying drawings is a jar closed and at the same time
protected against fraudulent refilling according to my said invention shown partly
in vertical section and partly in side elevation. Figure 2 is a plan of the top of
the closed and protected vessel.

page_text: a is the body of the jar. b the screwed neck thereof. ca rubber packing ring
maintained in position on its seat by the inner vertical lip d-e is the loose lid or
cover the lip of which rests directly upon the packing ring c-f is a soft metal
trade mark capsule here shown with openings formed in the top thereof to show
the lid or cover beneath. This capsule is screwed onto the neck of the vessel and
fits closely round the sides of the lid to which and to the vessel itself it is securely
united by cement. g is a screwed cap or collar (here shown as a collar) of stout
metal or other suitable rigid material and h the inner projecting flange between
which and the top of the Trade Mark Capsule is interposed the ring or disc of
rubber felt or other suitable yielding material i to facilitate the tight screwing
home of the said cap or collar for the purpose of forcibly pressing the edge of the
lid or cover down upon the packing ring c. The cap or collar g serves also to
protect the trade mark capsule at the side and hold it firmly against the screwed
neck of the vessel. In opening the vessel the cap or collar g is first unscrewed for
which facility is afforded by the milled edged annular projections kk, the Trade
Mark Capsule f is then opened or removed which cannot be effected without
damaging or destroying the same, and lastly the loose lid or cover e now fully
exposed is lifted off. It will thus be seen that whilst a tight closure is obtained
the destruction of the Trade Mark Capsule fin opening the vessel is a safeguard
against fraudulent refilling as the imperfect condition of the said capsule indicates
that the vessel has been tampered with.
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 combination of externally screwed neck of vessel-packing ring-loose lid-
Trade Mark Capsule enclosing the lid and secured to the vessel-and rigid screwed
cap or collar arranged substantially as and for the purpose specified.
