Claims. (.CL. 222F527),

The present: invention pertains: to removable; pouring spouts: fon use: witln liquidi containers; such as emergeney gasoline cans; oils cans, and the and has. particular relation to. such spouts having improvedcrimprfabnicateth construction obviating the: necessity fon soldering"v the; parts together.

In the. mass productionand use of removable spouts for gasoline cansand. the like, the neqpinedl heat and flux for soldering together the various tin-plated parts. mars the. appearance of" the article and. subjects it toeasy rusting, As a result such spouts usually have to bepainted, which is an undesirable attempt to remove the difliculty since the painting operation is relatively expensive and the paint itself easily chipped in use, or perhaps removed by solvents poured through the spout.

It is therefore an object of the present invention to provide a simple, effective, and economically made removable pouring spout of the type described which may be fabricated of tin-plated parts without the necessity for soldering and with the removal of the difliculties mentioned above.

Further objects and advantages of the invention will become apparent as the following description proceeds, taken in conjunction with the accompanying drawing, in which:

Figure 1 is a fragmentary perspective view of a liquid container or can equipped with a pouring spout embodying the present invention;

Fig. 2 is a vertical section of a cap employed in the present spout and shown prior to assembly;

Fig. 3 is a vertical section of the cap and a cooperating thimble or sleeve illustrating a step in the assembly of the present spout;

Fig. 4 is an exploded elevation, partially in section, illustrating another step in the assembly of the present spout;

Fig. 5 is a fragmentary vertical elevation of the present spout;

Fig. 6 is a fragmentary vertical section of the completely assembled spout;

Fig. 7 is a plan view, partially in section along line 7-7 in Fig. 5, of the spout of the present invention; and

Fig. 8 is a vertical section of a partially assembled pouring spout embodying a modified form of the present invention.

While particular embodiments of the present invention are shown and described in some detail, it is not intended that the invention be thereby limited. On the contrary, the intention is to cover all alterations, modifications, and equivalents falling within the spirit and scope of the invention as defined by the appended claims.

Referring now to the drawing, the removable pouring spout of the present invention is shown in Fig. 1 as attached to a liquid container 10 of conventional form having an orifice surrounded by a threaded neck (not visible). The spout is formed of tin-plated sheet metal parts of unique configuration which are crimped or clamped together without any necessity for soldering or ice painting. shown: in: Figsg. 1 and 6; comprises am apertured cap. 11'. adapted to: be: threaded; on the.- neck. ofi'the: container 10. The margins of a. central: opening 12 in. the: top. of the cap are crimpedt in the. form: of; a; collar. 13? extending upwardly and outwardly over an in; turned. flange 14 of an' abutting, cups-like: thimble. or-sleeve; 15. A metal ferrule 16, which: is crimped to: one end. of a pouring tubee 1'1; is received withinithe. upstanding thin1ble-and: secured% by peripheral crimping on clamping. The; thimble 15 is1 thusi securely attached to: the cap 11. around its: central opening 122 and. the ferrule 1 6- and: tube 17- are securely clamped within the: thimble; The, resultant spout is simple. in, nature: and: easily assembled, at the same: time, being: leak-proof and formed; without: themseof solder on aisoldering; operation.

A- further description of the individual. components; and final construction of the pouring: spout. may best proceed; by reference: to the steps; in its assembly, as illustrated: by Figs. 2. through ,6r. Ln: 2f the base: or cap 11; for the. spout. is. shown: in, its initiah configuration as;

' a: generally, cylindrical; member-having; a. skirt 18 formed:

to.-be screwed on the threadedmeck'of the can 10,-. While: various; arrangements; may be used: for the removable: attachment: of the. cap to the can, a threaded: COI1l16C-- tion isconvenient and is. showna. The cap: 11'. has, a: center aperture or opening 12:. defined; irr its top portion! 19 with an upstanding collar or flange- 13; sunrounding the opening.

As shown in Fig. 3, the first step in assembly is the positioning of the generally cylindrical and cup-like thimble or sleeve 15, having an inturned circular flange 14 on its lower end, over the upstanding collar 13 with the flange 14 abutting top portion 19. The collar 13 is crimped outwardly over the flange 14 to lock the cap 11 and thimble 15 together (Fig. 4). A strainer or screen 20 may optionally be pressed inside the thimble to form an integral part of the spout, held in place by ferrule 16.

As illustrated more completely in Figs. 1 and 4, a length of tubing 17, in this instance a spirally constructed flexible metal hose, is equipped with ferrules 16 extending over either end, the ferrules being crimped onto the hose by inturned collars 21 at their extremities. The tubing or hose 17 is secured to the cap 11 and thimble 15 by the insertion of one ferrule 16 into the thimble. The two parts are then positively crimped together along peripheral squeeze lines 22 resulting in vertical pinched ears 23 (Figs. 5 and 6). A unitary pouring spout is thus formed without any necessity for soldering, but through simple crimping operations of cooperating elements results in a strong, simple, and leak-proof construction. 'Ihe spout may be removably attached to the neck of a container formed to cooperate with the skirt of the cap and the flexible hose may be swung to any angle during pouring operations.

In Fig. 8 there is shown a partially assembled pouring spout embodying features of a modified form of the invention intended to facilitate the storage of the spout within, and the closure of, the container when the spout is not in use. In this embodiment, two caps 11 and 11a similar to that described above are positioned and secured in back-to-back relation, the lower cap 11 having a collar 13 around its central opening 12 crimped to extend through the opening 12 of the upper cap 11a. The upper cap 11a is formed without such a collar. The two caps and a thimble 15 having an inturned flange 14 are all secured together as shown by the crimped collar 13 of the lower cap bent outwardly to engage the inner side of the flange 14, with the outer side of the flange abutting against the top portion 19 of the upper cap 11a and securing it against the top portion of the lower cap 11. The pouring tube or hose, with a ferrule on its end (not shown in Fig. 8), may then be crimped within the thimble 15 as described above.

The modified spout shown by Fig. 8 may be employed as a removable spout by attaching the lower cap 11 to the neck or orifice of a container in the same manner as the first embodiment described. However, when the spout is not in use and the container is to be closed, the caps may be inverted and the upper cap 11a placed over the neck of the container with the tubing or hose extending into the interior of the container in stored position. A suitable closure plug (not shown) may then be screwed into the lower cap 11a to seal the container.

From the foregoing description, it will be apparent that the pouring spout of the present invention provides a simple, strong, and leak-proof construction easily fabricated by crimping, spinning, or stamping operations of tin-plated sheet metal parts without any necessity for a soldering operation. For this reason, the spout, when complete, is not marred or disfigured and presents a pleasing appearance without the necessity of painting.

I claim as my invention:
