Patented Jan. 3, 1950 UNITED STATES PAT ENT OFFICE I :NU'RSING BOTTLE Theodore Bailey, Habana, Cuba Application-February 27, 1948, Serial No. 11,670

2 Claims. 111

This invention relates to ar'i'ursirig bottlecomprising improved features for maintaining the contents ofthebottleat a desired temperature over a substantial period of time.

A further feature ofthe invention relates to means for rendering the bottle substantially unbreakable.

Anotherobject is to provide a device of this kind comprising c'onst'ructionaldetails facilitating the complete cleansing of all parts of the bottle.

Another object is to provide means 'in such a bottle for eliminating vacuumdfl'side theb'ottle and consequent non-operation'thereof.

Another feature of the invention is the production of a bottle havingthese'edvantages and adapted for efficient low-cost manufacture.

These and other objects and'f'eatures are attained by the means described'herein and illustrated in the accompanying drawings, in which:

Figure 1 is an elevationahview partly in section, of the bottle in operative condit-ion.

Figure 2 is a cross sectional view on line 2-2 of Figure 1.

Figure 3 is a cross sectional view on line 3-3 of Figure 1.

Figure 4 is an enlarged vertical cross section of the juncture means connecting the upper and lower parts of the bottle.

With detailed reference to the drawing: the bottle comprises an open-top outer container 8 preferably manufactured of transparent plastic and which may be formed with vertical outer ribs 9 to facilitate grasping thereof. At the top, container 8 has an annular shoulder l above which the extremity of the container is threaded as at H. The inside surface of the container has vertical ribs 12 and bottom ribs I3 projecting therefrom. Ribs I2 extend somewhat short of the top of the container, as at [5 (Figures 1 and 4).

An inner container I4, of semi-rigid or flexible material such as rubber, is receivable in the outer container 8 and rests in contact against the ribs 12 and I3 whereby it is spaced from the inner surface of the outer container.

An inner ring member I6 is formed with a depending flange I'l fitting within and secured to the top of the inner container M, as at 3. The ring member also comprises a lateral flange l9 resting on the tops of the various ribs I2 of the outer container, and an inwardly-offset vertical flange 2B for receiving a nipple 2|.

Nipple 2| is formed with a relatively rigid bottom rim 22 comprising a horizontal section 23 and an upright section 24. The'former rests against the top edge of vertical flange 20 of the inner ring member, and the upright section 24 embraces said flange. Section 24 extends downwardly short of the lateral flange IQ of said ring member, as at 25.

An outer ring member 26 comprises an inwardly threaded flange 2? for engaging the threaded section I! of the outer container. It furtherprovides an external shoulder 28, an exteriorlythreaded vertical flange 29, and an inturned top portion 3% which, when the outer ring member is threadedly positioned on said section -II, bears against the horizontal section 23' of the nipple rim 22, for holding the nipple inplace. The under face of inturned portion 30 and of vertical flange 29 are provided with communicating grooves 3l--32,'and the top edge and outer face of flange 2B of the inner ring member are also provided with communicating grooves 33- 34, all

'of' which gr'oovesprovide for communication of the interior of the inner container with theouter atmosphere, the air passing, as suggested by the arrows in Figure 4, beneath the flange 22 of the nipple rim. Thus pressures inside and outside said container are equalized and vacuum and flow stoppage prevented, despite withdrawal of liquid from the inner container during use.

The channels formed between the ribs [2 of the outer container are substantially sealed by the lateral flange [9 of the inner ring member so that insulation spaces are thus established, effective in maintaining the temperature of the contents of the inner container over relatively long time periods.

A cap 35, having interior threads 36 at its open end, is threadedly receivable on the exteriorlythreaded flange 29 of the outer ring member, for covering the nipple during non-use. The outer container may, if desired, have secured thereon or molded therewith a ring 31 adapted to receive any convenient rod or extension, as of a cradle, for holding the bottle in operative position, for which purpose also, a set screw 38 may be employed in connection with said ring.

What is claimed is:

l. A nursing bottle, comprising an outer container having one end closed and its opposite end open, the open end being externally screw threaded, said container being provided upon its closed end with internal ribs and upon its side with longitudinal internal ribs which terminate near and short of the open end of the container, an inner flexible container mounted within the outer container and having one end closed and its opposite end open, the closed end of the flexible container contacting the ribs of the closed end of the outer container and the side of the inner container contacting the longitudinal ribs, the flexibility of the inner container permitting of complete contact between the inner container and said ribs, an inner ring member including a first annular portion and a second annular portion and a radial shoulder near their meeting ends, the second annular portion being inserted into the open end of the flexible container and the shoulder inserted within the open end of the outer container to contact with the longitudinal ribs, said first annular portion being provided with a vent groove extending over its outer face and end and leading into the inner container, a nipple having a radial shoulder to engage over the end of the first annular portion and an annular skirt to receive the first annular portion, and an outer ring member including a first annular portion having a shoulder to engage over the shoulder of the nipple and a second annular portion having internal screw threads to engage with the external screw threads of the outer container and a shoulder to engage over the open end of the outer container and the shoulder of the inner ring member, the first annular portion of the outer ring member having a vent groove formed in its inner face and extending about the shoulder of the first annular portion of the outer ring member and communicating with the groove of the inner ring member.

2. A nursing bottle, comprising an outer container having one end closed and its opposite end open, the open end being externally screw threaded, said container being provided upon its closed end with internal ribs and upon its side with longitudinal internal ribs which terminate near and short of the open end of the container, an inner flexible container mounted Within the outer container and having one end closed and its opposite end open, the closed end of the flexible container contacting the ribs of the closed end of 4 the outer container and the side of the inner container contacting the longitudinal ribs, the flexibility of the inner container permitting of complete contact between the inner container and said ribs, an inner ring member including a first annular portion and a second annular portion and a radial shoulder near their meeting ends, the second annular portion being inserted into the open end of the flexible container and the shoulder inserted'within the open end of the outer container to contact with the longitudinal ribs, a nipple having a radial shoulder to engage over the end of the first annular portion and an annular skirt to receive the first annular portion, and an outer ring member including a first annular portion having a shoulder to engage over the shoulder of the nipple and a second annular portion having internal screw threads to engage with the external screw threads of the outer container and a shoulder to engage over the open end of the outer container and the shoulder of the inner ring member.
