VACUUM BOTTLE WITH 'POURER Louis F. Phelps, Flint, Mich.

Application June 11, 1954, Serial No. 436,069

1 Claim. (Cl. 215-13) The present invention relates to a generally conventional-type vacuum bottle, for example, a Thermos bottle, which is distinguishably different from the type ordinarily found on the market in that it is provided with a handy and reliable pouring spout herein referred to broadly as a pourer.

Pouring liquid from a vacuum bottle is unhandy and in most instances, the liquid may spill and drip over the exterior surfaces of the jacket-like casing in a messy and undesirable manner. Therefore, there has long existed a need for a practical pourer which is such in construction that it will achieve the desired pouring result, this in a feasible and reliable manner. it follows, therefore, that the instant endeavor has to do with a vacuum bottle having a simple, economical and desirable pourer.

Another object of the invention is to transform a marketed type vacuum bottle, for instance, the aforementioned Thermos bottle, into one which shall now have a handy pourer and to do this by adding the pourer thereto without requiring remodeling or alterations in the style bottles which are now in use.

A further object of the invention is to provide a pourer which, after it is applied in the desired manner, does not interfere with the usual dome-type cap which is currently supplied on vacuum bottles.

Briefly summarized, the invention therefore has to do with the combination of a vacuum bottle having a body and neck, a jacket protectively encasing the body, a thimble-like fitting encircling said neck and screwthreaded and adapted to accommodate an attachable and detachable screw-type hooding and closing cap, the upper end of said fitting having an inturned endless lip encircling said neck in spaced relation, a pourer having a collar fitted into the existing space between the lip and neck and snugly embracing said neck and also having an outwardly flaring flange projecting beyond the neck and lip and providing a funnel-like spout, and a packing ring encircling said collar and interposed between latter and encompassing portions of said fitting.

Finally, it is an object of the invention to provide, as a new article of manufacture, a readily attachable and detachable plastic or equivalent washable, sanitary pourer which may be purchased and installed by the purchaser for use on vacuum bottles which are already in use but are not supplied with suitable pouring facilities.

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

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

Figure 1 is a view in section, fragmentarily shown, of the vacuum bottle constructed in accordance with the principles of the present invention.

Figure 2 is a perspective view of the attachment-type pourer by itself.

Referring now to the drawings with reference numerals and accompanying lead lines the part of the overall construction which is here conveniently ref-erred to as the United States Patent 2,807,385 Patented Sept. 24, 1957 ice vacuum bottle per se is denoted by the numeral 4 in Figure 1. This is a conventional-type which has integrated spaced walls 6 and 8. It includes a body portion with a reduced or restrictedneck 10 at the upper end having anendless web 12 which ordinarily serves as the pouring lip. This bottle 4 is encased in an .appropriate protective jacket 14. The type of jacket shown is one which includes a thimble-like truncated conical member which is here conveniently referred to as fitting 16. This has screw-threaded connection at 18 with the body portion of the jacket, has a reducedupper neck portion 20 with an inturnedlip 22 spaced from theneck 10 and in addition has screw threads at 24 to accommodate the usual attachable and detachable dome-like closing cap (not shown). For the most part there is a packing ring orgasket 26 interposed between theneck portion 20 and thebottle neck 10. The complemental pourer is denoted by thenumeral 28 and it is of appropriate washable material. An appropriate grade of commercial plastic may be used for this purpose. The pourer is characterized by an endlessannular collar 30 which is of appropriate elasticity and this extends down through the space between the inturnedlip 20 and the neck portion of the bottle where it snugly encircles said neck portion. It is preferably tapered to feather-edge form so that the gasket orring 26 may be interposed between the collar and theneck portion 20 of thefitting 16. It also includes an outwardly flaringendless flange 32 which is of an appropriate diameter. This forms a shallow funnel-like pourer as is obvious.

The outside diameter of the flange is less than the body portion of the fitting carrying thethreads 26 so that the pourer does not interfere with the application and removal of the aforementioned closing cap (not shown). Thus the collar is telescopically fitted between theportions 20 and 22 of thefitting 16 with the collar snugly encircling the neck of the bottle and with the packing ring interposed in the manner shown to provide a satisfactory seal between the parts.

It is believed to be within the purview of the invention to employ any appropriate material. For example, experimental models have shown that it is practical to employ a precision made aluminum pourer instead of the plastic type.

Novelty is predicated on the pourer in combination with the vacuum bottle as well as the pourer by itself.

Since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows:

In combination, a vacuum bottle having a body portion and a neck portion, a jacket protectively encasing the body portion, said jacket being open at its upper end, a thimble-like fitting carried by the open upper end portion of said jacket and encircling said neck portion and screw-threaded and adapted to accommodate an attachable and detachable screw-type closing cap, the upper end of said fitting being also open and having an inturned endless lip encircling said neck portion in spaced concentric relation, and a readily applicable and removable pourer having an annular collar gradually tapering in cross-sectional thickness to feather-edge proportions and wedged and fitted into the existing space between the inner peripheral edge of said lip and exterior surface of said neck portion and snugly embracing said neck portion, said pourer also having an outwardly flaring endless flange joined to the upper portion of said collar and projecting radially beyond and overhanging the neck portion and lip and providing a funnel-like spout, and the 3 4 Outside diameter of said flange being predetermined and 2,099,174 Payson Nov. 16, 1937 less than the outside diameter of the body portion of the 2,582,934 Parsons Jan. 15, 1952 aforementioned thimble-like fitting, and a packing ring 2,707,574 Klebenuw May 3, 1955 encircling said collar below said lip and interposed between the collar and the encompassing portion of said 5 FOREIGN PATENTS 682,122 France Feb. 10, 1930 48,597 Denmark Apr. 3, 1934 References Cited in the file of this patent 499,303 Great Britain Jan 18, 1939 UNITED STATES PATENTS 504,147 Great Britain Apr. 20, 1939 1,448,996 Donath Mar. 20, 1923 1
