IMPROVEMENTS IN THE MEANS OF STOPPERING OR CLOSING THE MOUTHIS OR OPENINGS OF JARS, BOTTLES, POTS AND ANALOGOUS ARTICLES
Year: 1884

page_text: I, WILLIAM EDWARD CLAY SPENCER, Chemist, of Canterbury Terrace, Maida
Vale, in the County of Middlesex, c/o. Day, Davies and Hunt, Patent Agents,
321, High Holborn, in the County of Middlesex, do hereby declare the nature
of my Invention for "IMPROVEMENTS IN THE MEANS OF STOPPERING OR CLOSING
THE MOUTHIS OR OPENINGS OF JARS, BOTTLES, POTS AND ANALOGOUS ARTICLES,"
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 certain improvements in the means of stoppering or
closing the mouths or openings of jars, bottles, pots, and analogous articles, the
especial objects of the improvements being to provide simple, effective and
improved means of securely closing such openings, and to dispense with such
contrivances or means as are at present used for the purpose, and which I consider
to be more or less defective.
The improvements constituting the present Invention are represented on the
accompanying drawings as applied to a shallow pot such as is in common use by
Chemists and others for containing various powders, pastes, pomades, and other
substances but it will, of course, be understood that such representations are
equally illustrative of the similar application of the Invention to other analogous
articles to which it is intended to apply the improved means of stoppering or
closing their mouths or other equivalent openings.
On the accompanying drawings, Fig; 1, represents a plan view of the said pot,
showing the application of the Invention thereto, and Figs; 2, and, 3, are side
elevations thereof, looking respectively in the direction of the arrows 1, 2.
The present improvements consist in the formation externally of a raised rim, 3,
with which the upper part of the pot or other article, 4, is formed, of laterally
extending flanges, 5, which are placed at an equal distance from the top edge of the
pot so far as they extend around and gradually taper in depth from both sides as
they extend from the sides of the pot as most clearly seen in Figs; 2, and, 3. The
raised rim, 3, is formed continuously around the pot, but the flanges, 5, formed
externally thereof are not so formed, and they may be two or more in number of
corresponding extent, and they are placed opposite or equidistant apart, with
intervening spaces, 6, between their ends. The said flanges 5, and rim, 3, thus

page_text: form locking channels, 7, cach of which is open at the one end, 8, and is closed at
the other end by stops, 9, or equivalent closing of the channel, the object of which
is to arrest the turning movement of the lid, 10, in a certain determined position
when being placed in position.
The lid is made of a corresponding formation, the parts, however, being revorsely
formed, and so disposed as represented in the under plan view Fig; 4, and in tho
sectional elevations thereof (respectively taken at 11-12, 13-14,) illustrated in
Figs, 5, 6, as that the flanges, 15, of the lid can be readily placed in the spaces
between the ends of the flanges, 5, of the pot, when being placed in position, they'
being of less extent than such spaces, so that on a turning movement being given
to the lid in the direction of the arrows 16, or to the pot in a contrary direction
the parts are caused to engage with each other, not with a screwing action, but in
parallel planes, and thus the separation or loss of the parts is prevented.
The flanges, 15, are formed flush on their lower faces to fit on to the edge, 17, of
the pot, and they are formed on their inner sides in a manner corresponding with
that of the inner sides of the flanges, 5 :-The channels under the flanges, 15, aro
open throughout their length, and the arresting of the lid in its intended position
is effected by the entering end of its flange, 15, coming into contact with the
stopped end, 9, of the locking channels, 7.
The material of which the pots or other article or the lids or other covers thereof
to which the present improvements are intended to be or may be applied, is made,
is not at all material to the present Invention.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed or carried into
practical effect I declare that what I claim is :-
The hereinbeforo described improvements in the means of stoppering or closing
the mouths or openings of jars, bottles, pots and analogous articles, such improve-
ments consisting in the novel and peculiar conformation of the meeting or closing
parts (3, 5, 6, 7, 8, 9 and 15,) of such pots or other articles, and of the lids or other
covers thereof, substantially as described with reference to the accompanying
drawings.
