and other Receptacles.
I, ALFRED DUNHILL, Manufacturer of Cycle Accessories, of 145 to 147, Euston
Road, in the County of London, do hereby declare the nature of this invention
to be as follows:-
My invention relates to a new or improved means for practically excluding,
or nearly so, the air from tins, bottles, and other receptacles, and so preserving
their contents, and is applicable to that class of tin or other receptacle having the
cover or lid thereof made in the form of a cap fitting over the end or ends of such
receptacle.
I will now describe the nature of my invention in connection with a hollow
cylindrical tin case suitable for containing a repairing outfit for pneumatic cycle
tyres. This cylindrical case has its end at either extremity closed by means of
a lid in the form of a cap. I place on the outside of this cylindrical case, a closely
fitting tube or cover of rubber or other suitable elastic substance or material. This
rubber tube or cover may be the same length, or thereabouts, as the cylindrical case,
so that when the caps forming lids on the ends of the latter are in position, the
said rubber or the like tube covers the line of junction between the cap and case
or receptacle, thus rendering the case or receptacle practically air tight, or nearly
Or this rubber or the like tube or cover may be replaced by two shorter
similar tubes or covers situated one at each end of the said receptacle, so as to
cover the line of junction between the cap and case or receptacle, thus leaving
a length in the middle of the case or receptacle uncovered by rubber or the like.
80.
Surrounding the central portion of the cylindrical case, and outside the rubber
or the like tube or cover, I place a tightly fitting band or bands of any suitable
substance or material, such band or bands being of less length than the cylindrical
case or receptacle, so that the ends of the rubber tube covering the sides of the
caps are left exposed. This band may, if required, form a label indicating the
contents of the receptacle, or it may bear an advertisement or any other required
written or printed matter. Or such band or bands may be replaced by a suitable
metal or other clip or clips.
When it is now required to remove one of the caps forming the lids of the
receptacle, the exposed end of the rubber tube is rolled back, thus leaving the
required cap free to be removed in the usual way. When such cap is again
replaced the exposed end of the rubber tube is rolled up into its former position.
It is obvious that my invention may be applied to any other shape of receptacle
of metal, glass, or other suitable substance, so long as the cover thereof is in the
form of a cap; for instance: - the invention will be found very useful for excluding
the air, or nearly so, from the contents of glass bottles or tubes having lids or

page_text: covers in the form of metal or other caps, for containing medicines, such as
tabloids, pills, and the like.

New or Improved Means for Excluding the Air from Tins, Bottles,
and other Receptacles.
I, ALFRED DUNHILL, Manufacturer of Cycle Accessories, of 145 to 147, Euston
Road, in the County of London, 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 relates to a new or improved means for practically excluding,
or nearly so, the air from tins, bottles, jars, and other receptacles, or for preventing
the contents of such receptacles from evaporating, and so preserving them.
The invention, though preferably applied to receptacles of the shape hereinafter
described, may also be applied to any shaped receptacle of glass, metal, or other
suitable substance.
In carrying my invention into practical effect, I fit on to the neck or other
convenient part of such receptacle, a tightly fitting sleeve of rubber or like
material. When the receptacle is closed, this rubber or like sleeve extends over the
cap, stopper or the like forming the cover thereof, covering the line of junction
between the cap and receptacle, and thus preventing the ingress or egress of air
or other gas to or from the receptacle.
When it is required to open the receptacle the rubber sleeve is rolled back from
the cap or stopper and retained in its withdrawn position by means of a ridge or
groove on the receptacle, or by a ridge formed on the said sleeve itself, the cap
or stopper being now exposed and capable of removal in the ordinary way.
That part of the rubber sleeve which is to remain immovable, may be firmly
retained in position on the receptacle by means of a band or clip of paper or other
substance, such band or clip serving also as a label, or bearing an advertisement,
or any other written matter, if required. Or, instead of such band, a metal wire
may be used to effect the same purpose.
I will now proceed to further describe my invention in connection with the
accompanying drawings, in which the same letters of reference indicate like parts
in the various figures.
Fig. 1 represents a cylindrical glass bottle a (suitable for containing medicinal
tabloids, smelling salts, or other like articles) having a ridge b formed near its
open end, which latter is closed by a metal, glass, or other suitable cap c. A
rubber or like ring or washer being placed on the bottle between the edge of
the cap c and the ridge b.
Tightly fitting this bottle for part of its length, and also extending over the
sides of the cap c, so as to cover the line of junction between the latter and the
bottle a is the rubber or like sleeve d. The lower end of this sleeve may be
secured in position by the band of paper or other suitable substance e, which may
serve also as a label, or carry an advertisement, or other matter. Or this band 'e
may be replaced by a metal wire.
Fig. 2 is a view of the cylindrical bottle a having the rubber sleeve d rolled
back below the ridge b, so that the cape can be removed.

page_text: Fig. 3 shows a cylindrical bottle a having the rubber sleeve d rolled back and
retained by a groove g, so that the cap c can be removed.
Fig. 4 shows the top of a cylindrical bottle a having a groove such as g formed
therein.
Fig. 5 is a longitudinal sectional view of a cylindrical metal case f suitable for
containing a repair outfit for the pneumatic tyres of cycles, fitted with inven-
tion.
my
This case is fitted with a cap c at either end and is encased in a tightly fitting
rubber or like sleeve d secured in position by a band of paper or like e, which latter
may also serve as a label or the like, as previously explained. In this figure
the sleeve d is shown covering the sides of the cap at one end of the case f, but
rolled back from the cap and behind the ridge b at the other end of the case.
is obvious that either one or both of the ridges b in this figure might be replaced
by a groove such as g (Fig. 4) or that the rubber sleeve might be replaced by two
shorter rubber sleeves one at each end of the receptacle.
Fig. 6 shows my invention applied to a scent bottle.
It
Fig. 7 shows a bottle a, having a rubber sleeve d rolled back over a ridge b
formed thereon, and fitted with a stopper t; the end of this stopper fitting into
the bottle, being reduced and having a rubber or like washer w placed thereon.
Fig. 8 shows a similar bottle and stopper to that shown in Fig. 7 but the rubber
or like sleeve d is rolled up over the stopper t so as to preserve the contents of
the bottle.
Fig. 9 is a view of a stopper t and washer w such as is shown in use in Figs. 7
and 8.
A ridge such as 6 or a groove such as g is found very useful to retain the portion
of the rubber or like sleeve when rolled back so as to expose the cap or stopper,
but I may also apply my invention to receptacles not having such ridge or groove.
Moreover, the rubber or like sleeve may, if preferred, be applied to receptacles
without the use of a band such as e, or a wire or its equivalent.
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) A bottle, tin, jar or like receptacle having a ridge or its equivalent formed
thereon, a rubber ring or washer situated at the point of junction with the stopper
or cap closing it, and fitted with a rubber or like sleeve secured in position by a
band or wire, substantially as described.
(2) A bottle, tin, jar, or like receptacle, having a rubber ring or washer situated
at the point of junction with the stopper or cap closing it, and fitted with a
rubber or like sleeve having a ridge formed thereon and secured in position by
a band or wire, substantially as described.
(3) A bottle, tin, jar, or other like receptacle with its cover in the form of a cap
or stopper, fitted with a rubber sleeve held in position by a band, substantially as
and for the purpose described.
(4) A bottle, tin, jar, or other like receptacle with its cover in the form of a cap
or stopper, fitted with a rubber sleeve, substantially as and for the purpose
described.
(5) The herein described method of and means for preserving the contents of
bottles, tins, jars, and the like receptacles.
