OF CHICAGO, ILLINOIS, A CORPORATION 0F NEW YORK POURING N OZZLE Application filedl January 21, 1929. Serial No. 834,066.

My invention relates to dispensing containers and pouring spouts for containers, and seals for such containers and spouts. One obgect of my invention is the provision of a container, for example a bottle, which shall have a pouring lip having a minimum tend- 'ency to become obstructed, and having a maximum efficiency in pouring. Another object 1s the combination with such a lip of a. seal for the nozzle which is effective even after the pouring lip has been employed. Other obj cts will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein- Figure 1 is a. side elevation of one form of my invention;

Figure 2 is a removed;

Figure 3 is a vertical axial section;

Figure 4 is a side elevation with removed;

Figure 5 is a front elevation of the nozzle;

Figure 6 is a plan view of a variant form of nozzle; with the cap partly broken away;

Figure 7 is a side elevation of the device of Figure 6, with the cap in section;

Figure 8 is a plan view of a further variation of my device, with the cap removed;

Figure 9 is a front elevation of the nozzzle shown in Figure 8, with the cap in position; Figure 10 is a side elevation with the cap in position; and

Figure 11 is a plan view of the cap.

Like parts are indicated by like symbols throughout the specification and drawings.

Referring first to the form of Figures 1 to 5, A generally indicates any suitable bottle or container being herein illustrated as a plan view with the cap the cap pouring bottle having the neck A1 the handle A2 and the head generally indicatedl as A", at the top of the neck. The head portion As is provided .with a lower circumferential flange A4 and a thread or wedging member A".

Formed in the u per surface of the head A is the sealing mem er generally indicated as B, such sealing member surrounding the pouring aperture B1. Its upper edge lies generally in a single plane, as indicated at Bz for example in Figure 5. It is expanded laterally at one point, as at B5, to form a pouring lip, the head `being cut away or recessed thereabout and therebeneath, as at B4. Note that the extreme tip B5 of the lip B3 is shown in Figure 2 as terminating within the periphery of the head, whereby it will not normally engage the ange C1 of the cap C, when such cap is in position.

In the employment o f the cap the sealing member C2 engages the sealing surface B, or the upper plane B2 thereof. The screw threads orV wedge portions C on the cap engage the interrupted thread A5 and in response to rotation of the cap and seal C2 is firmly seated against the sealing member B of thenozzle or head. It will be realized that owing to the fact that the lip does not engage the flange C1 of the cap, that it cannot become sealed thereagainst by any liquid which li'as passed over the lip. f There may be some tendency to bind against the seal C2, but experience indicates that even when a container of this type is employed to dispense glue or similar adhesive substances, when the cap is unscrewed the shearing action is sufficient to free the seal C2 from the portion B.

In order to make this shearing action easier, or to make the rotation of the cap easier I may provide laterally expanded portions C to be engaged by the handle finger.

Referring to the form of Figures 6 and 7 I may employ, in the place of; thescrew cap above described any suitable friction cap. Therefore I employ a head D with the sealing surface or member D1 of the pouring lip D2' substantially identical with those shown in the earlier gures the head being recessed or cut away as at D3 about and beneath the lip. A cap D, with its seal D, is held in position upon the head, as by the clamping circumferential liange D6. It will be realized that since the cap does not have to be rotated, the cap need not be circular. In practice such caps are made circular, but an oval or other non-circular formy of cap and flange may be employed.

Referring to the form of Figure 8 and following I illustrate a head E having opposed parallel sides E1 channeled or indented as at E2 to receive the inwardly extending ridges E3 of the cap generally indicated as E4. The seal of such cap E5, engages the opposed sealing member E6 ofL-the head. It will be understood that the pouring lip and adjacent parts are substantially as shown in the earlier forms.

It will be realized that whereas I have described and shown a practical device, nevertheless many changes might be made in size, shape, number and disposition of parts Without departing from the spirit of my invention. I therefore wish my description and drawings to be as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.

The use and operation of my invention as are follows:

In all the forms of container or spout herein shown, I obtain the advantage of a pouring nozzle having a pouring lip which lies in the plane of and is` part of a sealing surface, such as B, which is engaged by a seal, such as C. This sealing surface, and the pouring lip,"all lie within the normal area of the surrounding cap, whether the cap be screwed on or pressed on or slid on. In all forms herein shown the pouring lip, although enclosed within or beneath the seal, is an effective pouring lip, the head being recessed or cut away beneath it, to form a drip edge. The result is a pouring container which pours efficiently and which may be sealed after use, and which is sealed by the very act of restoring thel cover to the pouring nozzle.

It will be understood, that in claiming in the claims wedging locking means, I wish to include not only screw threads in the sense in which the term is generally used, but any cam or wedging engagement whereby rotation of thecap draws down its seal against the sealing surface on the head.

I claim: f

1. In a pou`ring container, a neck, a head on said neck, said head including a sealing surface lying in a single plane, a pouring lip formed in said sealing surface, thehead being recessed beneath said pouring lip and a cap adapted to engage said head in locking engagement, and to engage said sealing surface in sealing contact, said sealing surface a n d pouring lip lying within the periphery of said cap.

2. In a' pouring container, a neck, a generally -circular head on said neck, said head including a non-circular, unbroken, continuous sealing surface lying in asingle plane,

locking engagement, and to engage said sealing surface in sealing contact.

3. In a pouring container, a neck, a gener-I ally circular head on said neck, said head including a non-circular, unbroken, continuous sealing surface lying in a single plane,

such sealing surface being laterally deformed to form a pouring lip, the head being recessed beneath said ypouring lip, and a generally circular cap adapted to engage said head in locking engagement, and to engage said sealing surface in sealing contact, the head being provided with circumferential wedging4 face of said head, the plane of said sealing v surface being generally perpendicular to the axis of the neck, the periphery of said head being generally circular but eccentric in relation to thev aXis of the neck, the sealing surface being laterally deformed to form a pourng lip, the head being recessed beneath said pouringlip, and a generally circular cap adapted to engage said head in locking engagement and to engage said sealing surface in sealing contact.

6. In a pouring container, a neck, a generally circular head on said neck, and a sealing surface lying in a single plane on the upper face of said head, the plane of said sealing surface being generally perpendicular to the axis of the neckythe periphery of said head being generally circular but eccentric in relation to the axis of the neck, the sealing surface being laterally deformed to form av pouring lip, the head being recessed beneath said pouring lip, and a generally circular cap adapted to engage said head in `locking engagement and to engage said sealing surface in sealing contact, the head being provided with circumferential wedging locking means, such means being interrupted adjacent the pouring lip, the cap being flanged to engage such wedging locking means.
