I, GUISEPPE VICENZO DE LUCA, of 6 and 7 Long Lane, Aldersgate Street, in the
City of London, Glass Bottle Manufacturer and Merchant do hereby declare the nature
of iny said Invention for "IMPROVEMENTS IN THE NECKS OF BOTTLES AND JARS to
be as follows:
"
In closing bottles and jars, such as are commonly employed to hold preserves and
the like, with corks, it is found that if the neck is made to taper even slightly to a
smaller diameter towards the inside the cork has a tendency to rise and become loose ;
and if the necks are made cylindrical, or conical in the opposito direction there is a
difficulty in making the cork sufficiently air tight.
Now according to my invention the neck is so shaped that the cork is, when driven
in, retained by an inward annular projection so that it has no disposition to rise and
the said shape of the neck moreover affords facilities for attaching a cover of
parchment, skin, or the like, so that it may be closed by a cork only, or by a cork and
skin, or by a skin only.
I make the necks of cylindrical or nearly cylindrical shape, and, preferably, about
midway in the length of such cylindrical or nearly cylindrical part I make one or
more narrow grooves or hollows around the outside, causing a corresponding annular
ridge, or projection, or ridges or projections on the inside of the neck.
The thus formed inwardly projecting annular ridge or ridges serve at once to retain
the cork when it has been driven so that part of its length has passed it or them, and
at the same time assists, by the constriction of the cork which it occasions, in
making the stoppering air-tight.
The annular groove or grooves on the outside of the neck, corresponding with
the ridge or ridges within, serves to receive and retain the string or wire securing
the covering when the mouth is covered with a skin or the like whether a cock
is also used. or not..
The neck may be finished at top with the usual flange-like rim or left plain or at
pleasure.

page_text: I GUISEPPE VICENZO DE LUCA, of 6 and 7 Long Lane, Aldersgate Street, in the
City of London, Glass Bottle Manufacturer and Merchant, do hereby declare the
nature of my said invention for "IMPROVEMENTS IN THE NECKS OF BOTTLES AND JARS
to be as follows.:
دو
In closing bottles and jars such as are commonly employed to hold preserves-and
the like, with corks, it is found that if the neck is made to taper even slightly to a
smaller diameter towards the inside the cork has a tendency to rise and become loose;
and if the necks are made cylindrical, or conical in the opposite direction, there is
difficulty in making the cork fit sufficiently air tight.
Now according to my invention the neck is so shaped that the cork is, when driven
in, retained by an inward annular projection, or an annular cavity or groove so that it
has no disposition to rise, and the said shape of the neck moreover affords facilities for
attaching a cover of parchment, skin, or the like, so that it may be closed by a cork.
only, or by a cork and skin or by a skin only.
I make the necks of glass bottles and jars of cylindrical shape, and preferably
about midway in the length of such cylindrical or nearly cylindrical part I make
one or more narrow grooves or hollows around the outside, causing a corresponding
annular ridge or projection, or ridges or projections on the inside of the neck.
In the Manufacture of earthenware bottles and jars the process of forming them
and the nature and properties of the material do not lend themeselves readily to the
production of exactly the same form and 1 find it more convenient and preferable to
make one or more grooves or hollows around the inside of the neck into which the
cork swells when it is driven tightly into the neck. Such annular grooves are
conveniently formed by the application of a suitable tool within the neck before the
bottle or jar is removed from the mould or the wheel on which it is spun.
In the drawings annexed Fig. 1 represents a glass jar or bottle such as is ordinarily
used to contain preserves, constructed according to my invention; Fig. 2, is a vertical
section of the same; Fig 3, is a section of the neck of a similar bottle closed by a
cork; Fig. 4, represents a similar portion of a bottle closed by a skin drawn over it;
Fig. 5, represents a similar vessel made of earthenware; Fig. 6, is a section of the
same; Fig. 7 is a section of a neck closed with a cork, and Fig. 8, represents the top
of a similar bottle or jar closed by a piece of membrane tied over it. A is the bottle or
jar; bis the neck; C, is a cork; d, is an annular groove or hollow round the outside
of the neck into which a parchment or similar covering may be drawn and tied as
shewn in Figs. 4, and 8.
In glass bottles the production of this groove. or hollow round the outside of the
neck may be produced by a rim in the mould whereby a corresponding rim or
projection e is formed on the inside of the neck by which when a cork is driven in,
that part of it which passes the said rim is compressed and constricted by the rim,
below which it expands by reason of its elasticity and fills the neck as shown in

page_text: figure and is thus sufficiently prevented from rising out of its place. The annular
groove or grooves on the outside of the neck serve to receive and retain the string or
wire securing the covering when the mouth is covered with a skin or the like whether
a cork is used or not.
EL
In the manufacture of earibenware bottles and jars either in moulds or on the
potters wheel an impression on the outside of the neck does not readily produce
corresponding bulging of the inside of sufficient sharpness to answer the intended
purpose; I therefore make in earthenware vessels a groove or hollow d' instead of
a raised rim, so that the cork when driven in may expand into and fill the same,
as shewn in Fig. 7, and be thereby held in its place.
In some cases, and for some purposes, I prefer instead of only one to make two
or more such cork retaining rims or hollows and they serve when a cork has been
driven in so that part of its length has passed it or them, not only to retain the
cork, but also by breaking the continuity of any crevices or defects in the surface
of the cork by which air might pass in or out, to make the closing of the bottle
or jar more nearly porfect that it would be in a similar vessel with an ordinary
neck, and this is matter of very great importance and value to the manufactures of
some kinds of preserved articles of food.
The neck may be finished at top with the usual flange-like rim or be left plain as
shown in Figs. 1 and 2, or at pleasure.
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
1. Constructing bottles and jars with an annular rim projecting into the neck
substantially as described and shewn in Figs. 1, 2, and 4.
2. Constructing bottles and jars with an annular cavity or groove in the neck into
which the cork may expand substantially as and for the purpose described and shown
in Figs. 5, 6, 7, and 8.
3. Constructing bottles jars and the like with necks formed substantially as described
and shewn in the drawings, fitted to be closed with a cork, or with a cork and skin, or
with skin or the like alone.
