LAWRENCE A.V NORTON, OF CHICAGO, ILLINOIS.
SCREW-NOZZLE FOR CANS.
SPECIFICATION forming part of Letters Patent No. 486,293, dated November 15, 1892.
Application tiled September 17,1391- Serial No. 405,965. (No model.)
To @ZZ whom it may con/cern:
Be it known that I, LAWRENCE A. NORTON,
' the following is a specification.
My invention relates to cans furnished with.
screw-nozzles and caps for closing the same.
The ordinary screw-cap nozzleV does not make an air-tight closure. In sirup and many other nozzle-cans it is, however, desirable that the can should be capable of being sealed airtight. Heretofore screw cap nozzles have sometimes been furnished with supplemental lcorks or Stoppers to increase the tightness of the closure and sometimes with gaskets; but neither of these devices affords a perfectlyair-tight closure, and their use is attended with inconvenience and expense.
The object of my invention is to so construct the screw-cap-nozzle can that it may be hermetically sealed cheaply and conveniently and at the same time readily opened by simply unscrewing the cap.
To this end my invention consists, in connection with a can furnished with a screwnozzle and screw-cap, of an annular recess or channel at the base of the nozzle, into which the lower rim of the cap projects and which is filled with sealing-wax, thus forming a hermetical seal to the nozzle. The annular recess for the sealing-wax or other sealing material is preferably formed integral with the screw-nozzle by turning up its lower rim.
The invention further consists in the novel devices and novel combination of vparts and devices herein shown and described, and more particularly pointed out in the claims.
In the accompanying drawings, which form a part of this specifcatiomandin which similar letters of reference indicate like parts, Figure l is a side elevation of a can embodying my invention, and Fig. 2 is an enlarged vertical sectional view of the screw-cap nozzle.
In the drawings, A represents a sirup or other sheet-metal can. B is the screw-nozzle, and C the screw-threaded cap which closes the nozzle. The head A of the can is furnished with the usual cap groove or channel a, surrounding the opening a in the head of the can, and in which cap-groove the lower rim or base of the nozzle ts and is securely soldered in place. At the base of the screwnozzle B is an annular recess or channel b,
into which the lower head or rim c of the Screw-cap C projects, so that when the annular recess b is filled with wax or other sealing material D the same will form a hermetical seal between the nozzle and cap. The recep- 6o tacle or annular channel b for the sealing material is most conveniently formed by turning or rolling up the lower edge or rim b of the nozzle B, substantially as shown in the drawings. channel b a kind of dovetail shape in cross-l section, so that the sealing material may be better protected and more securely fixed 1n place, I form a roll b2 at the extreme edge of the upturned outer rim b', as is clearly indi- 7o cated in Fig. 2 of the drawings. The roll or upturned edge b2 also gives a smooth finish and prevents danger of injury to the fingers from the raw edge in unscrewing the cap.
The screw-cap C is also furnished with a turned edge or projecting rim c at its rim or base. By this means the screw-cap-nozzle .can may be securely and hermetically sealed,
and all that is required to open the can is simply to break away or remove the sealing- 8o waX D and unscrew the cap. At'ter the can has once been opened it may again be temporarily hermetically sealed while the contents of the can are being used by simply refilling the sealing-receptacle b with semiliquid or other suitable sealing material.
I claim- 1. The combination, with a sheet-metal can A, having a head A', furnished with a capgroove a, of a sheet-metal nozzle B, provided 9o with screw-threads stamped or pressed thereon and having its lower edge or rim b rolled or turned up outwardly to form an annular channel b, said turned-up rirn or edge fitting in the cap-groove a and being soldered to the head A', and an imperforate sheetmetal screw-cap C, tt-ing over the nozzle and having its lower edge or rim projecting into said annular channel b, said annular channel being lled with a sealing material or wax, roo
To give the sealing receptacle or 65 whereby said can may be hermeteally sealed, substantially a-s specified.
2. The combination, with a sheet metal screw nozzle B, provided with corrugated screw-threads and having an upturned rim b at its base, forming an annular channel or receptacle for the sealing material, of an imperforate Sheet-metal screw-cap fitting over Said nozzle and having a rolled edge or rim c, projecting into said annular receptacle or 1o channel for the purpose of hermeteally sealing the nozzle, substantially as specified.
