IMPROVEMENTS IN BOTTLES AND STOPPERS THEREFOR"
Year: 1885

page_text: I DAVID WELLESLEY BELL of N° 14, Milton Street, in the city of London,
Merchant, do hereby declare the nature of the said invention for "IMPROVEMENTS
IN BOTTLES AND STOPPERS THEREFOR" to be as follows:-
-
In screw stoppered bottles as hitherto constructed no means have been provided
for preventing the stopper becoming partly unscrewed or loosened from the effect
of jar, shock or otherwise to which such goods are subjected in handling and in
transit and in practice we have found that considerable loss arises from leakage in
consequence of the stoppers becoming loose or partly unscrewed.
The object of my improvements is to obviate this defect and for this purpose
I form or provide the interior of the mouth of the bottle at that part against
which the usual elastic washer on the stopper is pressed with one or more inden-
tations, serrations or projections of a size and shape such that it or they while
allowing the stopper to be screwed into or unscrewed from the bottle in the
ordinary manner will when the stopper shall have been properly sorewed into the
bottle hold it in its place and prevent it becoming unscrewed or loosened during
handling or transit.
I also propose to serrate that portion of the stopper which receives the washer
in order to prevent the washer turning on the stopper.

consequence of the stoppers becoming loose or partly unscrewed.
The object of my improvements is to. obviate this defect and for this purpose
I form or provide the interior of the mouth of the bottle at that part against

I also propose to serrate that portion of the stopper which receives the washer
in order to prevent the washer turning on the stopper.
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
1. Forming or providing the interior of screw mouthed bottles with one or more
indentations serrations or projections in the manner and for the purpose substantially
as described.
2. Serrating screw stoppers in the manner and for the purpose hereinbefore
