Improvements in and relating to Vessels for Containing and
Discharging Methyl Chloride or other Volatile Liquids.
I, HEINRICH HELBING, of 63, Queen Victoria Street, in the City of London,
Chemist, do hereby declare the nature of this invention to be as follows:-

-
This invention relates to improvements in vessels or containers for holding and
preserving volatile liquids such as methyl or ethyl chloride or mixtures containing
the same, and which may be used as auto-sprays" for medical or surgical pur-
poses by reason of the vapour pressure of their contents projecting a fine stream of
vapour or liquid through a capillary orifice opened at will.
These vessels or containers which have found extensive employment, are made of
glass or metal, and for the sake of convenience in re-filling and in controlling
the emission of their contents the capillary orifice or orifices are closed with metal
screw or bayonet caps, or other metallic fittings, luted to the glass with cement
in the case of glass containers.
When the volatile liquids it is desired to employ contain dissolved in or mixed
with them substances which attack and corrode metals, such as iodine, the metal
fittings become more or less quickly unfit for use, whilst the contents may likewise
be deteriorated or decomposed.
By my invention I am able to overcome these drawbacks in substituting for metal
caps and fittings, caps and fittings of earthenware or china, a pad of india rubber
or other suitable material being inserted directly above the orifice, and pressed
down upon by the china or earthenware cap, so as to secure a hermetically closed
joint. Or where it is desirable to avoid the luting of the china or earthenware
fittings to a glass vessel, I employ vessels made throughout of porcelain, china
or glazed earthenware and fitted with caps of like material.
In this way I am able to preserve solutions or mixtures of volatile liquids con-
taining iodine or other substances which attack metals in vessels which may be
used as auto-sprays as required without the fittings being corroded or blocked, or
the contents deteriorated.

following statement:-
"
This invention relates to improvements in vessels for containing and discharging

or the contents deteriorated.
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. In a vessel for containing and discharging volatile liquid's the use of a non-
corrosive cap of earthenware, china, porcelain or the like fitted with a non-cor-
rosive resilient substance as and for the purposes specified.
2. A device for containing and discharging volatile liquids consisting of a non-
corrosive vessel made of earthenware, china, porcelain or the like, and a non-
corrosive cap as described in Claim 1.
