MILK BOTTIIE.

Application filed October The present invention relates to receptacles suci as are intended for repeated use, and has reference more specifically to bottles such as are used for the Vending and transporting of milk, cream, and similar liquids,

and which class of bottles are generallyclosedat their mouths by means of a disc shaped paste-board cap. In the present form of milk bottles intended for repeated use, an annular flange is formed in the neck of the'bottle so as to form a seat for the usual paste-board cap which is used for closin the bottle. This abrupt annular flange fbrms a pocket or shelf allowing sediment and contaminated matter to gather about the flange for the breeding 'of germs whichbecome mixed with the milk when next being poured from the bottle. This flange also prevents proper and thorough. cleansing of the bottle when again desiring to use the same, due to the inability of being able to thoroughly remove the contaminated matter from the abrupt angular pocket formed by the annular flange.

It is therefore a primary objectof this invention to provide an improved bottle for repeated use in the vending of milk, cream, and similar liquids, embodying sanitary features whereby foreign and contaminated matter will be prevented from forming in the neck of the bottle.

' A further object of the invention is to provide an improved milk bottle having the mouth thereof so formed as to permit of the use of the usual standard, size card-board cap, and with the seat for the capso formed as to permit of ready and thorough cleaning of the mouth'of the bottle.

A still further embodiment of the inven- 40 tion is in so formingthe seat for the cap, as to permit of the liquid in the bottle to readily drain back into the bottle and not become lodged on an abrupt annular flange such as is apparent with the present types of milk bottles employinga disc shaped cap for seating upon the annular flange formed in the neck of the bottle.

A still further object of the inventionresides in the provision of an improved milk bottle embodying the aforementioned features, wherein the construction of the bottle is such as to permit of its being manufactured with machines now in common use for the making of milk bottles, and in which 12 thereof disposed in 13, 1925. Serial No. 62,296.

machines the necks of the bottles are shaped 65 bya plunger which is inserted and withdrawn from the neck of the bottle.

Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken inconnection with the accompanying drawing forming a part of this specificatlon, and in which drawing Fig. 1 is a View of a milk bottle showing the upper portion thereof in central Vertical section and constructed in accordance with I my invention, and showing the customary disc shaped cap in position for closing of the bottle.

Fig. 2 is a top plan view of a milk bottle constructed in accordance 'with my invention.

Fig. 3 is a transverse section on line 33 of Figure 1, looking in the direction of the arrows; and, Fig. 4- is an enlarged vertical fragmentary sectional view of the upper portion of the bottle and illustrating more clearly certain details of construction of the neck of the bottle.

Referring to the drawing in detail, and wherein similar reference characters desig: nate corresponding parts throughout the several views; 5 designates generally a milk bottle of usual appearance and formation externally, having a reduced neck portion 6, the upper end or mouth of which is provided with the usual enlarged external rim 7 having a flattened top or end face 8. This neck portion 6 is formed with its least internal diameter at a point substantially midway the length of the neck as designated at X, and from which point the internal surface of the neck flares or tapers outwardly both toward the mouth or end face 8 as at 9, and toward the main body portion of the bottle as at 10.

Formed on the inner surface of the neck "6 and preferably spaced equidistant apart, are a plurality of inwardly extending polygonal shaped ribs 11 having their major axes extending in longitudinal relation to the neck, and with the confrontin inner faces aralle' relation to one another as clearl i1 us'trated in Figure 1. These lugs or ri s 11, which are substantially triangular shape in formation, mer e at their lower ends into the inner surface of theneck 6 at a point of its least internal diameter X, and extend upwardly with their inner faces 12 in parallel relation to the axis of the neck, to a point spaced below the end face 8, in a manner. so that a slight shoulder 13 is formed at the upper end of each rib, and which shoulders provide a stop for the disc shaped cap 14 wheninserted into the mouth of the bottle; It will here be further stated, that the ribs 11 which extend upwardly from a point con- I stituting the least internal diameter of the neck, and which ribs are disposed wholly within area of the upwardly flaring portion 9, have their inner confronting faces 12 spaced apart at their upper ends, a distance equal to the internal diameter of the neck at the point X. Thus it will be seen that a plunger for shaping the neck with such ribs I may be readily inserted and withdrawn from the neck, since the internal formation of the neck at all points above the point X is of either equal or greater diameter from the point X upwardly to the end face 8. These spaced apart ribs, and as is readily apparent,

allows for the inner surface of the neck to be continued in an unbroken line between theribs to the extreme upper end of the neck, thus allowing the liquid to readily and quickly strained.

It can be readily seen that by soproviding a plurality'of these spaced apart ribs about the inner surface of the neck 6, that an 1 effective stop or seat will be provided for the .usual cardboard cap 14 and by merging all portions of the ribs into the surface of'the neck in arcuate shaped fillets, no abrupt angular pockets or shelves will be formed for retaining foreign matter and contaminating the liquid in the bottle. A bottle so constructed, will permit of the neck being readily and thoroughly cleaned, since a brush or othercleaning device will readily remove any sediment which may have-collected about the ribs. It will also be apparent that with a milk bottle so constructed, the disc shaped cap may be easily removed by'merely slipping a knife blade or similar fiat article into the mouth of the bottle between two of the lugs,'since the inner surface of the neck condrain back into the bottle unreufactured with the equipment now in common use for producing milk bottles.

Various minor changes may be made to the form of the invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.

I claim:

1. A bottle of the character described, embodying a neck portion having its least internal diameter at a point spaced below the mouth of the bottle, and a plurality of spaced apart ribs extending upwardly from the point of least internal diameter of the neck and terminating short of the mouth of the bottle, with the diametrical distance between the confronting faces of the ribs at their upper portions at least equal to the dimension of the least internal diameter of the neck. e

2. In a milk bottle having a conventional milk bottle body and a conventionally shaped milk bottle neck, said milk bottle neck at the inner periphery of the opening thereof having spaced projections, said projections bcing below the top edge of the neck and constituting .the sole bearing support for the milk bottle cap in its seahng position.

3. In a milk bottle having aconventional milk bottle body and a conventionally shaped milk bottle neck having a relatively large openingupwardly flaring with an increas ing diameter, said neck in the flaring opening thereof at the inner periphery thereof having spaced projections providing cap supporting shoulders having rounded fillet junctures with the inner surface of the neck and from said shoulders merging into the material of the neck at the restricted part of the opening without the forming of under shoulders facing into the milk bottle body.
