Oct. 29, 1929. w. M. DECKER NURSING BOTTLE Filed March 3, 1927 Ira/e12 i or; I m M M Patented Oct. 29, 1929 UNITED STATES WILLIAM MORE DECKER, OF BUFFALO, NEW YORK NURSING BOTTLE Application filed March 3, 1927., Serial No. 172,475.

This invention relates more particularly to the type of sanitary nursing bottles comprising a neckless, wide-mouthed food-cell or receptacle and a so-called breast-nlpple having a correspondingly large base stretched over an annular bead at the top of the cell.

In applying a breast-nipple to such a cell or receptacle, the breast is liable to be drawn down farther over one side than the other, distorting it more or less and impairing or destroying its desired mobility. Such overstretching, moreover, weakens it in time, causing it to lose its grip on the cell, as well as shortening the life of the breast-nipple. One ob ect of the invention is to provide the food-receptacle with simple stop means for predetermining the proper and uniform application-limit of the breast-nipple to the receptacle, thus guarding against the objections resulting from its distorted or improper application.

A further object is to so contrive the stop device that it serves also as a guard for bafiiing attempts of the nursing infant to get its fingers under the base of the breast and pull it 0d the food-receptacle.

In the accompanying drawings :F igure 1 is a side elevation of a nursing bottle .embodying the invention. Figure 2 is a vertical section of the upper portion of thesame. Figure 3 is a side elevation of'the food-cell or receptacle. Figure 4 is a cross-section on line H, Fig. 3.

Similar characters of reference indicate corresponding parts throughout the several views.

The neckless, wide-mouthed food-cell 10.

l thereon around the entire circumference of the breast. This sto -bead is spaced such a distance from the loc ing bead that the lower edge of the breast abuts against the upper side of the stop-bead when the breast is stretched over the locking bead far enough to securely interlock therewith. In the preferred embodiment of the invention, the space or groove 15 between the two beads is just wide enough to receive the base-flange of the breast, as shown in Fig. 2, and the upper face of the stop bead is fiat to form an abrupt seating shoulder for the breast-nipple, as shown in the drawings, but the form or cross section of the stop-bead may be modified within the scope of the appended claims, if desired. By this stop-provision, unequal stretching and distortion of the breast-nipple is obviated and its desired mobility and flexibility is preserved.

This improved cell is also especially desirable in connection with the breast-nipple shown and described in Letters Patent of the United States No. 1,207 ,37 7, issued to me December 5th, 1916. The dome-shaped breast of that nipple has an external annular rim midway of its height to prevent its collapse. When this wide-rim breast begins to collapse, its lower portion folds inward and downward and reduces the internal diameter of the mouth of the food cell, arresting the further descent of the mid-rib at the constricted cellmouth and preventing complete collapse of the breastmipple. This infolding of the breast cannot take place when it is drawn down over the cell farther on one side than the other, but by providing the cell with the stop or limitation head 14, such overdistcntion is prevented and'the breast and its anticollapsing mid-rib are permitted to function properly.-

The stop-bead performs" the additional function of a guard or baflie under the lower edge of the applied breast which prevents the babe from dislodging or removing it.

This improvement not only insures the uniform application or adjustment of the breastnipple to the food-receptacle and prevents too easy removal of the same from the receptacle by a nursing infant, but by preventing over-stretching and weakening of the breast preserves its necessary stron gri on the receptacle for a long period,'t us engthening its life.

I claim as my invention 1. In a nursing bottle, the combination with a neckless, wide-mouthed food-receptacle having an annular bead at its upper end and a breast-nipple therefor having an annular internal locking ribat its base engageable under said receptacle-bead, of a second annular bead formed on the receptacle below and in spaced relation to said first-named bead to be engaged by the lower edge of said locking rib and constituting a guard for limiting and restricting the placing of the breastnipple over the food-receptacle, both of said beads projecting beyond the face of the receptacle.

'2. In a nursin bottle the combination of a breast-nipple iaving a locking rib at its base, and a neckless wide-mouthed food-receptacle having a pair of annular beads both projecting beyond the surface of the receptacle and spaced apart to form an intervening annular groove Whose bottom is substantially in line with the receptacle-surface and which is approximately as wide as the locking rib of the breast-nipple, the lower bead constituting a stop to predetermine the applicationliniit of the breast nipple and the upper bead constituting a locking element over the side and top of which the lower portion of said nipple is adapted to snugly bear in a stretched condition.
