14 Claims.

My invention relates to containers, and it has to do particularly with spout structure therefor.

One of the objects of my invention is to provide an improved, separately formed spout struc- 'ture for containers, which structure is permanently secured to the container by means forming an outlet of a character adapted to receive sealed closure means.

Another object is to provide an arrangement of the foregoing character wherein the spout structure is secured to the container wall in such a manner as to prevent leakage past the connection between such spout structure and container wall.

A more specific object of my invention is to provide a container wall having an opening therein defined by an upstanding annular flange having a bead formed at the free end thereof for reception and securement of sealing means, which bead serves also to fixedly retain spout structure in position surrounding said flange and in position to readily permit attachment and detachment of such sealing and closure means.

Other objects and advantages will become apparent as this description progresses and by reference to the drawings, wherein,

Figure l is a vertical sectional view, partially in elevation, of one form of container structure embodying my invention;

Fig. 2 is an enlarged section taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a somewhat reduced and separated top plan view of the spout structure of Fig. 2;

Fig. 4 is an enlarged section taken substantially on line 44 of Fig. 3;

Fig. 5 is a detached fragmentary sectional view of another form of spout structure which may be employed in accordance with my invention;

Fig. 6 is a sectional view of a closure structure embodying the modified form of spout structure .shown in Fig. 5, the seal and spbut elements of such structure being shown in position ready for final securement thereof; and

Fig. 7 is a view similar to Fig. 6 and showing the parts in their finally-secured form.

Referring particularly to Fig. 1 of the drawings, the container may comprise a metallic head 10 having a peripheral and downwardly-sloping segment 10 adapted to receive the closure and spout structure which will be described hereinafter. The adjacent container side wall portion 10 is slightly bulged or rounded to accommodate the rounded forward wall 11 of a metallic spout member 11. Although I have illustrated a particular form of container, it is to be understood that my spout and closure arrangement has utility in any form of container where similar advantages and results are desired.

Referring particularly to the spout and closure structure, it comprises an annular flange 12 struck outwardly from the container head segment 10 to define a circular opening. The container wall at the base of the flange 12 is provided with an offset portion 13 of irregular shape in plan outline defining an irregularly-shaped pocket which receives a similarly-shaped flange 14 of an internally threaded metallic bushing 14. The outer end of the bushing 14 is of such size and shape that it may be turned over and upon the outer or free end of the flange 12 to provide a rounded bead 15 at the outer end of such flange (Fig. 2). A gasket 16 is mounted in the pocket receiving the bushing flange 14- so that when these parts are secured together as stated the joint between the bushing and container wall is sealed against leakage. The thread ed opening formed by the bushing 14 is adapted to receive a threaded closure plug 1'7 and the irregular shape of the bushing flange 14 and wall portion 13 prevents relative rotation of these parts when the plug is screwed into the bushing. The closure plug 17 is provided with an enlarged head 17*, the lower peripheral edge of which is adapted to engage a. seat surface 15 formed on the inner surface of the bead 15 to limit the extent to which the plug may be screwed into the bushing, which extent is that sufiicient to properly compress a gasket 18 upon the seat 15 to eifect a fluid-tight, pressure-tight seal as between the plug and bushing. The structure so far described is similar to that disclosed in my copending application, Serial No. 609,093.

The closure plug 1'? is sealed against access and undetectable tampering by a seal cap structure which takes the form of a cylindrical metallic disk 19 and an outer metallic retaining ring 20 having a top portion 20 adapted to seat upon the slightly depressed peripheral edge portion 19 of the disk 19. This ring is also provided with a depending side wall portion 20 which is adapted to be uniformly contracted upon and behind the bead 15 to depress the seal cap structure as a whole upon the plug and at the same time depress a gasket 21 confined between the cap and the bead to effect a seal between the bead and the cap structure. This structure is similar to that disclosed in my said copending application except for the sectional form of the seal cap struc-- ture, and the cap is applied in place, preferably, in the manner disclosed in Letters Patent No. 1,887,435, granted in the name of Fleck W. Sample, on November 8, 1932.

- The spout member which I employ takesthe form of an annular base 11 and an upstanding spout body 11*, preferably (but not necessarily) of the shape shown in the drawings. The spout base 11 is provided with a central opening 22 defined by an upstanding annular flange 23 spaced from the spout wall 11*. This flange 23 serves, in cooperation with the closure structure already described, for attachment of the spout member to the closure structure. More particularly, the annular opening-defining flange 23 is preferably of a diameter and height suitable for snugly fltting the same over and around the flange 12 with the free edges of both these flanges terminating flush with each other (Fig. 2). In assembly of the structure thus described, the spout is mounted upon the flange 12 prior to the securement of the bushing 14 and the formation of the head 15; wherefore, when the end of the bushing 14 is turned over to form bead 15, the spout flange is securely and permanently fixed in place thereby upon the head flange 12. It will be noted that the spout structure is disposed at an angle with respect to the container head 10, so there may be occasions, upon tilting the container to discharge its contents through the spout and returning the same to its upright condition, that some of the contents will remain in the spout structure. It is desirable that these contents do not leak past the spout structure and upon the container head, and to avoid this I interpose a gasket 24 between the spout flange and head flange which is compressed into seal-tight relation when the spout is fixed in place in the manner described.

In Fig. 5, I have shown another form of spout which may be employed with the closure and seal cap means above described. This spout is of less depth than that shown in Fig. 4 and is provided with a central opening 25- defined by an upstanding anrular flange 26, which is of a diameter substantially equal to the outside diameter of the bead 27 (see Fig. 6) In this form, the closure structure, including. the wall flange 28, bushing 29 and bead 27, may be completely formed and the spout then applied thereto as best shown in Fig. 6. Referring particularly to Fig. 6, after the spout has been mounted in place, a seal cap structure 30 similar to that shown in Fig. 2 is passed over the head with its side wall 30 extending down over the spout flange 26. The side wall 30 of the seal cap is then contracted (preferably in the manner disclosed in the aforementioned patent to Fleck W. Sample) upon and behind the head 27 and around the head flange 28 in the manner of applying the seal cap 19 of Fig. 2, at which time the spout flange 26 is simultaneously contracted upon and around the head flange 28 and behind the bead 27 (Fig. 7) to firmly lock the same in place. With this arrangement, the seal cap 30 performs its functions as explained in connection with the previouslydescribed form and may be detached by the user in the ordinary manner; but, when this is done, the spout will remain fixed in place so that'it will serve its ordinary spout functions in the further use of the structure.

The operation and advantages of my invention will be apparent from the foregoing. The spout structure is firmly secured in place in a seal-type manner as the reinforced container wall opening is formed. The spout structure is so constructed and is so related to the container opening that the threaded closure means and seal cap may be readily and quickly applied thereto and removed therefrom.

When a container is filled with the desired contents, then closed and sealed, any tampering with the closure will be readily and quickly indicated. The authorized user may readily detach and seal cap by stripping back, tearing and distorting the cap ring flange 20 permitting removal of the cap disk 19 and unscrewing of the plug 17. After the seal cap has been removed, the closure plug 17 may be applied and removed at will without interference by the spout means. This structure is quite simple and is exceedingly inexpensive to manufacture, and it provides a sealed closure of maximum efiiciency with spout discharge features.

While I have shown and described only two forms of structure embodying my invention, it is to be understood that other changes in details and arrangements of parts may be made without departing from the spirit and scope of my invention as defined by the claims which follow.
