I CHARLES CHESWRIGHT of Leith Villa Parkhurst Road Holloway in the County
of Middlesex Manufacturer do hereby declare the nature of said invention for
"AN IMPROVED MODE OR METHOD OF AND MEANS FOR CLOSING AND PREVENTING
THE FRAUDULENT REFILLING OF BOTTLES JARS AND OTHER LIKE RECEPTACLES," to
be as follows:-
This Invention relates to the method of closing by the aid of screwed caps or
capsules and consists partly of further improvements on the invention set forth in
the provisional specification lodged with my application dated December 3rd 1884
No 15916. By the present improvements which are applicable to bottles as well
as to wide mouthed pots or jars I obtain a tighter closure in a more simple manner
than heretofore, prevent the fraudulent refilling of the receptacles so closed and
dispense with the use of loose fitting glass or other like lids or covers as also with
the use of rubber cork or other like packings heretofore interposed between the
junction surfaces, said packings being objectionable by reason of the capillary
action induced thereby which frequently results in exudation to a greater or less
extent of the contents of the vessel through the junction of the cover and the neck
of the vessel.
According to my present invention I convert the ordinary screw of glass or other
like rigid material moulded or otherwise formed round the outside of the neck of
the bottle or other vessel into a soft metal screw by forcing or spinning in any
convenient manner a soft metal collar or ring of Tin or its alloys or of "Betts'
metal in sheet form onto or over the threads of said rigid screw, the upper edge or
rim of the soft metal collar being laid or folded down onto the surface of the lip
of the vessel so as to cover the same and form a soft or yielding junction surface.
Having thus clothed the external screw and the edge of the mouth of the vessel
with the said metal or alloy I screw thereon a capsule of similar soft metal or alloy
the crown or top of which is thereby brought into direct metallic contact (without
necessitating the intervention of any packing) with the soft metal covered edge or
lip of the vessel. The foot of this capsule may be extended more or less below the
P

page_text: screwed portion of the vessel and be perforated or not and when screwed home be
secured by cement or otherwise round the body or neck of the vessel itself so as to
prevent its removal therefrom without injuring or destroying the said capsule thus
effectually preventing the fraudulent refilling of the vessel without detection.
Onto the aforesaid soft metal capsule which may be so fashioned or treated as to
constitute what is well known as a Trade Mark Capsule I screw a rigid or strong
cap of metal or other material by preference of Tin or its alloys, stout "Betts'
metal" or the like so as to bind the soft metal capsule beneath it still closer to the
soft metal covered screw on the vessel and also to press down the crown or top of
the said soft metal capsule forcibly against the soft metal covered edge or lip of
the vessel. In order to accomplish this in an even or uniform manner all round
the lip I interpose a cushion of felt or other soft or yielding material between the
crown of the soft metal capsule and the interior of the top or crown of the rigid
screwed cap.. I thus obtain an hermetical closure of the vessel without necessitating
the use of any interposed packing between the contact surfaces to which the
contents of the vessel can gain access.

page_text: I CHARLES CHESWRIGHT of Leith Villa Parkhurst Road Holloway in the County
of Middlesex 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 :-
This Invention relates to further improvements on the invention described in the
specification to my Letters Patent dated December 3rd 1884 N° 15916 whereby.
I obtain a tighter closure of bottles as well as of wide mouthed pots or jars formed
with a screw thread round the exterior of the necks or mouths thereof, in a more
simple manner than heretofore, I prevent the fraudulent refilling of the receptacle
so closed; I dispense with the use of loose fitting glass or other like lids or covers,
and also dispense with the use of rubber cork or other like packings heretofore
interposed between the junction surfaces of the receptacle itself and its cover, to
which packing the contents of the vessel .have heretofore had free access, which
was objectionable by reason of the capillary action induced thereby, frequently
resulting in the exudation to a greater or less extent of the contents of the receptacle
through the junctions of the said packing with the neck of the receptacle and its cap
or cover respectively.
Fig. 1 of the drawings annexed represents in half vertical section, and half
elevation a bottle or jar with my improved mode of closing and preventing the
fraudulent refilling of or tampering with the contents thereof, applied thereto.
Fig. 2 is a sectional elevation of a portion of the receptacle and its cover drawn
to a larger scale.
In carrying out my present invention I cover the ordinary screw a of class or
other rigid material of which the receptacle may be composed, and which is usually
moulded round the outside of the neck thereof as well as the upper surface of the
edge or lip of the receptacle by pressing spinning or otherwise applying in a
permanent manner around and into the screw a soft metal collar or ring b by
preference of Tin or its alloys or of Bett's metal in sheet form and by laying or
folding over the upper edge or rim of the said soft metal collar down onto the
surface of the lip of the receptacle as shown at c so as to cover the same and form
a soft or yielding metallic junction surface. Having thus clothed the external
screw and the edge or rim of the mouth of the receptacle with soft metal or alloy
I close the receptacle by screwing thereon a screwed capsule d of similar soft metal
or alloy the crown or top of which is thereby brought into direct metallic contact
with the soft metal covered edge or lip c of the receptacle and forms a perfectly
close junction therewith, without necessitating the interposition of any packing
between the parts.
In order to prevent any tampering with the contents of the receptacle or
fraudulent refilling of the same, I cause the lower or extended portion of the

page_text: capsule d, which is by preference made thinner than the upper screwed portion to
extend some distance, below the neck of the receptacle, and I secure the said lower
portion of the capsule by cement or otherwise round the body of the receptacle
itself so as to prevent its removal therefrom without the said capsule being injured
or destroyed, thus effectually preventing the fraudulent refilling of the receptacle
without detection. By making this lower portion d¹ of the capsule thinner than
the rest and further by perforating the same as shown in my drawings the
destruction of the capsule on attempting to unscrew it will be most effectually
ensured. Over the aforesaid destructible soft metal capsule d which may be so
fashioned or treated by coloring, stamping, or embossing for example as to con-
stitute what is commonly known as a "Trade Mark Capsule" I screw a rigid or
strong cap of metal or other material e, by preference of tin or its alloys, stout
Bett's metal or the like so as to bind the soft metal capsule d immediately beneath
it still closer to the soft metal covering b of the screw on the receptacle and also to
press down the crown or top of the said soft metal capsule forcibly against the soft
metal covered edge or lip at c of the receptacle. In order to accomplish this in an
even or uniform manner all round the lip I interpose a cushion of felt or other soft
or yielding material f in the form of a disc or a ring between the exterior of the
crown of the soft metal capsule d and the interior of the top or crown of the outer
rigid screwed cap e. I thus obtain an hermetical closure of the receptacle without
necessitating the use of any interposed packing between the contact surfaces to
which the contents of the vessel can gain access.
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. The mode of hermetically closing without the aid of packing, and preventing
the fraudulent refilling of bottles jars and other like receptacles formed with
external screw threads or inclines round the neck or mouth, by the use in com-
bination with a soft metal covering permanently applied to the screwed portion
and over the surface or edge of the lip, of a soft metal screwed capsule permanently
secured at its lower or extended portion round the body of the receptacle and in
direct metallic contact with the metal covered lip thereof-an outer rigid screwed
cap, and a cushion of felt or other soft material interposed between the crowns of
the rigid screwed cap and the soft metal capsule as specified.
2. Making the lower or extended portion of the aforesaid soft metal capsule,
whether plain or perforated, sufficiently thin to ensure the destruction thereof on
opening the receptacle as specified.
