IMPROVEMENTS IN COVERS FOR BOTTLES JARS AND THE LIKE
Year: 1885

page_text: I WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, in the County of Lancaster, and
323 High Holborn, in the County of Middlesex, Civil Engineer, do hereby
declare the nature of the said invention for "IMPROVEMENTS IN COVERS FOR
BOTTLES JARS AND THE LIKE" a communication from abroad by Léon Henri
Warin of Paris in the Republic of France, Merchant, to be as follows:-
The present application for Letters Patent has for its object the application of
the material known as celluloid to the purpose of closing hermetically the orifices
of vessels of all kinds, and especially the mouths of vessels of glass, pottery and the
like, such as those used in pharmacy whereby the elasticity of the material secures
perfect tightness in the closing of the vessel to which the cover is applied.
It is obvious that covers fulfilling the desired conditions may be made of any
suitable shape or pattern.
In carrying this invention into effect, a ledge or lip is formed round the mouth
of the vessel, or the same is formed slightly coned or recessed in such a manner
that the closing may be perfect, and the cover fit exactly round the orifice.
The celluloid cover is composed preferably of a single sheet of material stamped
in a mould. Any desired pattern may be imprinted thereon, or the cover may
bear a projection or handle for convenience of removal.
If desired the cover may be coloured to any required tint, or to the same colour
as that of the contents of the vessel for which it is intended.

page_text: I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, in the County of Lancaster, and
823 High Holborn, in the County of Middlesex, Civil Engineer, do hereby
declare the nature of this invention (a communication from abroad by Léon
Henri Warin of Paris, in the Republic of France, Merchant) and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The present application for Letters Patent has for its object the application of
the material known as celluloid to the purpose of closing hermetically the orifices
of vessels of all kinds, and especially the mouths of vessels of glass, pottery and the
like such as those used in pharmacy-whereby the elasticity of the material
secures perfect tightness in the closing of the vessel to which the cover is applied.
It is obvious that covers fulfilling the desired conditions may be made of any
suitable shape or pattern.
In carrying this invention into effect, a ledge or lip is formed round the mouth
of the vessel, or the same is formed slightly coned or recessed in such a manner
that the closing may be perfect and the cover fit exactly round the orifice.
The celluloid cover is composed preferably of a single sheet of material stamped
in a mould. Any desired pattern may be imprinted thereon or the cover may
bear a projection or handle for convenience of removal.
The annexed drawing, which shows the invention applied to a chemist's jar, will
enable the invention, together with the mode of carrying it out, to be better
understood.
The design serves only as a specimen to show the system in its most simple
application, but it is obvious that covers fulfilling the desired conditions may be
made of any suitable shape or pattern.
Figure 1 is an exterior view of the cover.
Figure 2 a vertical section of a jar with its cover on.
Figure 3, shows a different style of cover, the celluloid cover having a milled edge.
In these Figures
a is the cover, stamped out of a sheet of celluloid and of any suitable shape and
size.
b is the jar of earthenware, glass or other ceramic material, with a ledge or lip c,
which may be simply cylindrical or else slightly conical as shown in Figure 2.
.
If desired, the cover may be coloured to any required tint, or to the same colour
as that of the contents of the vessel for which it is intended.
Owing to the proportionately great elasticity and resistance of celluloid-
together with the polish of its surface-this material may be advantageously
employed whenever a good and tight fit is required.
Instead of forming the entire capsule or cover of celluloid, that portion
only of it forming the joint may be made of celluloid, and the remainder of
oil skin, parchment, paper, or other suitable material. Figures 4, 5 and 6 show

page_text: an application of this kind where a tight fit is obtained whilst the celluloid is
economised.
Figure 4 is a front view of a small bottle or jar furnished with the
improvement.
Figure 5 is a section of same.
Figure 6 is a side and top view of the ring.
b is the celluloid ring forced on to the neck or slightly conical collar of a bottle
or jar a; this ring holds in place a sheet of paper, cloth, parchment, or even a thin
sheet of tin or other metal or material c, which on being retained by the ring,
forms an economical capsule and one that can be easily taken off or put on.
Owing to this sheet being thin and flexible it can be easily placed between the
ledge or lip of the bottle or jar and the ring c. This celluloid ring affords sufficient
resistance to keep the cover tightly in position, and has enough elasticity to yield
to the different thicknesses of material employed as covers.
By this means the cover may be frequently renewed with great base and very
little cost, the celluloid ring can be used indefinitely.
The rings may be made of any diameter, and according to the size of the orifice
to be closed, they may also be of any suitable depth and thickness to insure
a tight fit.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated
to me by my foreign correspondent, I declare that what I claim is
1st. The application of a capsule, stamped out of celluloid, for closing jars or
flasks of all kinds, this capsule fitting on a corresponding ledge or lip at the orifice
of the jar, bottle, or receptacle, substantially as and for the purpose described.
2nd. The system of closing jars, flasks, bottles, or vessels of all kinds, by means
of a hoop or ring cut from celluloid and pressing on a sheet of paper, parchment, or
other material between the ledge or lip of the receptacle and this hoop or ring,
substantially as described with reference to Figures 4, 5 and 6 of the annexed
drawings.
