Improvements in Bottles.
1, RICHARD HENRY BARRETT, of The Oval, Hackney Road, in the County of
Middlesex, Glass Bottle Manufacturer, do hereby declare the nature of this
invention to be as follows:-
In the specification of a patent granted to me No. 12016 of 1886 I described a
bottle having projections standing out from the sides of the neck, the upper as
well as the under sides of such projections being made to incline downwards
and each projection being made to come to an edge or acute angle at the top
its upper end being made to terminate either in a line approximately parallel
with the central axis of the bottle or with the lower corner of such an end rounded
off. These bottles were closed with a cap having inward projections engaging
with the inclined projections on the neck.
In such bottles the cap is only held on by the friction of its projections on
those of the neck and if the neck is accidentally made a little too short the
pressure between the sets of projections when the cap is home is insufficient to
keep it securely in place.
According to this invention the upper sides of the projections on the neck are
helical as before but the lower sides in place of being helical are so curved that
as they descend their inclination to the horizontal becomes less and less and
ultimately they incline slightly upwards. When the cap is screwed home the
projections on it engage with the parts of the projections on the neck where
the inclination is slightly upwards and the cap remains more or less locked so
that it has little or no tendency to become unfastened.

Improvements in Bottles.
I, RICHARD HENRY BARRETT, of The Oval, Hackney Road, in the County of
Middlesex, Glass Bottle 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:-
-
In the specification of a patent granted to me No. 12016 of 1886 I described a
bottle having projections standing out from the sides of the neck, the upper as
well as the under sides of such projections being made to incline downwards

its upper end being made to terminate either in a line approximately parallel

In such bottles the cap is only held on by the friction of its projections on

pressure between the sets of projections when the cap is home is insufficient to
keep it securely in place.
According to this invention the upper sides of the projections on the neck are
helical as before but the lower sides in place of being helical are so curved that
as they descend their inclination to the horizontal becomes less and less and
ultimately they incline slightly upwards. When the cap is screwed home the
projections on it engage with the parts of the projections on the neck where
the inclination is slightly upwards and the cap remains more or less locked so
that it has little or no tendency to become unfastened.
Figure 1 is a side elevation of the cap,
Figure 2 a side elevation of the bottle, and
Figure 3 a vertical section of the bottle with the cap in place.
a are the projections on the neck, a¹ their upper sides, and a their lower
sides. is the cap having internal projections and an internal elastic pad b³.
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 projections on the neck whose lower sides are so curved that as they
descend their inclination to the horizontal becomes less and less and ultimately
incline slightly upwards.
2. Bottles substantially as described and illustrated in the drawings.
