^ Be it yknown that we, 'LEsTERiMARu-is Wmrn'and JARTHURFISH, citizens of the UnitedA States, and residents ofPerth. Am' boy, in the county of Middlesex and Stateing same, .such.as.are used to carry saidv solution -in considerable uantity, for example, in quantities up to fty gallons. The object of our invention is to provide a packfv age which shall-possess allthe advantages inherent` in the 4various types of such pack-l ages now known and avoidcerta'm'd1sad' vantages inherent' in them.

Formaldehyde is a Acommodity .which is widely used as a rawmaterialin the manufacture of. chemicals and other products.

It also finds Wide application for medicinaland pharmaceutical purposes.A Vlhile itfis .not corrosive to metals in the sense inwhich that term is'applied to common acids, yet

it does reactchemical1y-withiron, copper, wood and the other common materials from lwhich containers arefmade with the re-` sult that -the formaldehyde becomes contaminated with the products of .such reactionl Under' these clrcumstances, the 'I problem I i of procuring satisfactory packages has been difiicult. v

- Hitherto, the containers most commonly.

used have been barrels of selected white oak ofthe best quality sawed from the heart wood of the tree. Before use, these barrels are coated on the inside with molten paraffin. Barrels of this type, though widely used are subjectv to well known disadvantages, viz., they are expensive, and even when conv structed. wlith greatest care, they' ermit loss ofthe contents by absorption an leakage. This loss is the occasion of serious annoyance andfmay become prohibitive inv case of long distance lshipments unless the barrels are from time to time recoopered while' in transit. Moreover, the porous nature ofl even the best quality -of wood coated with the contents paraffin causes a direct loss of is the type of glass carboy ordinarily used for shipments of sulphuric and other acids. These are bulky and fragile. These disadvantages have practically eliminated the use of carboys for formaldehyde shipments except in vcases where'leakagemust be avoided at all cost and 1n 'cases where contamination of the formaldehyde, even so little as would be caused by the absorption of coloring and other matter from wooden barrels, must be avoided'.

It 1s found that the requisite qualities y reason of the absorption ofl l-JQEFICR Uswmrnaitna Amazon msn, or snai-'nf' autom NEW ,ina-snr,-

'The next step. is to assemble the sides'and'to'p of the casing and .Coat the same with metal, preferably by galvanizingwith zinc. The-bottom and the sealing cap 6 arealso similarly coated ina 1 ticular importance when the package is` separate operation, it being desirable that both the inside and the outside of the casing be so protected against ru-st and corrosion. Next the container 1- is inserted in the drum 5 and the bottom 11 attached so as to pref# n erably insure a double seam at 12, the bottom being then dipped into zinc or other molten metal, so that the latterv flows into the seam.

In assembling itis importantthat the con vtainer be in firm contact with the shoulder 8, and that the container frictionally engage thecorrugations 7 while the bottom 11 is so put on'as to exert a pressu-re tending lto hold the container firmly against the shoulder'S.

The package is. then filled through the opening2 in the. usual manner and the stopper 3 inserted and- Wired in-place. The last step is to apply the friction cap 6 and solder it to the head, as `by using a Wire 13, to enableA the solder to be readily stripped.

" What' We claim is 1. A liquid package comprising a .bottle shaped. container having a shoulder portion and neck of reduced diameter, acorrugated casing contiguous to the container along its sides and bottom, and provided With-a corsealed package absolutely insures that tainer, an end Wall on the casing provided with a removable closure therein adapted to seal the closure on the container.

3. A package for holding liquids comprising a Welded aluminum bottle shaped container provided with a shoulder portion and a neckv of, reduced size, avcorrugated metal casing for the container having its corrugations in contact with the sides and bottom of the container, an enlarged V-shaped oorrugation on the casing extending inwardly over theshoulder of the container to firmly position the same against the bottom of the casing, the side Walls of the Casing being continued above said enlarged :orrugartion in substantially the same direction as the main body portion of the side Walls, a stopper for the neck of the container, and an upper end Wall for the casing covering the 10 container and provided with a removable oap adapted to cooperate with the stopper and seal the container..
