1 2,707,574 DRIPLESS LIP ATTACHMENT FOR VACUUM BQTTLES Liliian Beatrice Klebenow, Zion, Ill. Application June 11, 19552, Serial No. 292,842 2 Claims. (Qt. 2i513) The present invention relates to an encased vacuum bottle having a pouring lip which greatly expedites the pouring of liquid from the bottle into a container or receptacle, such as for example, a drinking glass.

It is a matter of common knowledge that pouring a liquid from a vacuum bottle often results in spilling and splashing the liquid contents. It is believed that there has existed for quite some time the need for a pourer for this type of a bottle. The present invention, therefore, relates to an attachment which takes the form of a pouring lip and which is installed in a satisfactory substantially leak-proof position between the vacuum bottle itself and the jacket or casing which encloses the bottle.

More specifically, the invention appertains to an insertable and removable pouring lip attachment which is characterized by a principal unit having a ring-like portion carrying a visor-like extension defining the pouring lip, said ring-like portion also having a flange and said flange being provided with upper and lower packing rings to facilitate installation and practical use.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of drawings.

In the accompanying sheet of drawings wherein like numerals are employed to designate like parts throughout the views:

Figure 1 is a view partly in section and partly in elevation showing a conventional type vacuum bottle improved by the addition thereto of the pouring attachment herein revealed.

Figure 2 is a top plan view of the structure seen in Figure 1.

Figure 3 is a perspective view of the attachment by itself.

Figure 4 is a perspective view of the two packing rings forming portions or parts of the attachment.

Figure 5 is an elevational view of the lip and ring portion.

Figure 6 is a section on the vertical line 66 of Figure 5, looking in the direction of the arrows.

Reference is had to Figure 1 wherein the glass or equivalent vacuum cell or container is denoted by the numeral 8 and this is of customary double-wall construction and has an annular lip 10 on its outer end. This bottle or container is enclosed in a protective housing or jacket of more or less conventional type which is denoted at 12 and has a truncated conical portion 14 with an in turned annulus 16 and a down turned annular flange 18. This of course is what may be classified as a regular vacuum bottle. The attachment which is used in connection therewith to assist in pouring the liquid contents into a drinking glass or the like is denoted by the numeral 20. This is made up of several components or parts. The main part may be of light-weight sheet metal of a non-corrodible character or it could be of suitable commercial plastics. In any event, it includes a ring like portion 22 fashioned from the elongated band shown in Figure 5 with the respective ends abutting each other as denoted at 24. The visor-like extension 26 provides the pouring lip. In addition the band or ring is provided with a lateral flange 28 which forms a sort of a ledge. The upper packing ring 30 is seated on this ledge and surrounds the ring. This packing ring 30 is sufliciently strong and of a resilient character that it could constitute the sole means for retaining the band in ringlike form 22 and also holding the ends 24 together. This,

2,707,574 Patented May 3, 1955 however, is a phase of the matter which will be left up to the manufacturer to decide upon. In any event, the flange is provided with an upper packing ring 30 and also with a lower packing ring 32.

The pourer attachment is fitted and secured with requisite nicety in place in the manner best shown in Figure 1. In this figure it will be evident that the pouring lip is interposed between the outer wall of the bottle and the down turned flange 18. The packing rings provide the desired drip-proof or substantially leak-proof joint between the flanged portion and the respective bottle and jacket portions. What with the lip projecting in the manner shown, it is obvious that it provides a satisfactory means for pouring liquid and limiting the likelihood of spilling to a minimum.

The invention is simple, practical, easy to make and iiistall and represents that, which it is believed, will meet with the essential requirements of manufacturers and users.

It is also evident that the device revealed serves to reduce the number of parts entering into the combination, thereby not only increasing the efliciency of the structure as a whole but rendering the same less costly to manufacture and to otherwise simplify factors of assembling and sale.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

Having described the invention, What is claimed as new is:

1. In combination, a vacuum container comprising a vacuum bottle having a pouring neck, a protective jacket encasing said bottle and having a neck portion with a turned-in annulus and down-turned annular flange encircling said neck, a pourer embodying a split band encircling said neck and interposed between the latter and encompassing flange, the upper edge portion of said band having an upstanding visor-like extension providing a pouring lip which projects above the pouring neck, the lower edge portion of said band having a radial outstanding flange providing a ledge, and a resilient endless packing ring seated on said ledge and encircling said band.

2. In combination, a vacuum container comprising a vacuum bottle having a pouring neck, a protective jacket encasing said bottle and having a neck portion with a turned-in annulus and down-turned annular flange encircling said neck, a pourer embodying a split band encircling said neck and interposed between the latter and encompassing flange, the upper edge portion of said band having an upstanding visor-like extension providing a pouring lip which projects above the. pouring neck, the lower edge portion of said band having a radial outstanding flange providing a ledge, and a resilient endless packing ring seated on said ledge and encircling said band, said packing ring serving to bring the ends of said band into cooperating relationship, and a second packing ring underlying and attached to the bottom of said flange.
