(Cl. 128-252) This invention relates to baby nursers, and characters designate corresponding parts in all has for its object a nipple having an outlet which the views.

' the influence of the jaws of the baby, when nursing. Owing to the Y, or similar formation, it will open when collapsed regardless of in what radial direction the collapsing force is applied. That is, the orifice will open in any position the baby holds the nipple in its mouth.
Preferably, in order to prevent the passage of ,air from the nipple into the container, as when the baby is biting on the nipple and blows or gulps air, the nipple is provided with a check valve III near its entrance end. This is here shown as a flap valve composed of a thin piece of rubber mounted on the end of a plug II extending into the inner end of the nipple, and formed with a passage through which the milk, or food, flows.
In order to prevent folding of the collapsible container 4, to such an extent that it would lap over the entrance end of the nipple and hence prevent the outflow of food, stiffening means is provided, and that here shown is a comparatively rigid straight member I2 associated with the nipple, and here illustrated as projecting from the plug II. The plug II, with the stiffening strip I2, is here shown as a tube split at I3 and having a lengthwise portion, or half, removed below the plug.
In Figures 3 and 4, the nipple is shown as unprovided with the breast portion, and in Figure 8 the nipple is shown as unprovided with a check valve I0, and also unprovided with the plug II. The nipple, shown in Figure 8, is, with the exception of the outlet orifice, the usual nipple, but in addition is provided with acomparatively stifi base portion or annular flange 5.
In Figure 6, the nipple, with a collapsible container or bag, is shown as housed in an outer stiff shield, or container I6, this being usually a glass bottle, and the breast portion 20, of the nipple I00, is provided with means for interlocking with the upper open end of the bottle I6, and with a suction means for engaging the periphery of the bottle, and as here shown, the bead 40, corresponding to the bead I4 (Figure 2), is provided with an internal groove 4I facing the periphery of the bottle and preferable, this groove is divided up into arcuate sections by partitions I1, here shown as four in number, the edges of the partitions pressing against the bottle. The bottle I6 is provided with an external annular flange I8 at its open end, under which the bead 40 hooks. The groove or sections 4I are for a suction cup which causes the breast portion to adhere to the glass bottle.
The breast portion is provided with a suitable ventilating hole III to permit the air to enterthe outer container for the purpose of collapsing the inner container 4 as the food feeds outwardly therefrom, so that the food is subject to the outer atmospheric pressure through the collapsible bag,
and is not contaminated by coming in contact with the air of the .room.
In operation, the container 4 is filled, or partly filled, with milk, or other liquidfood, and the nipple I coupled in air tight relation thereto by reason of the contractile upper open end of the bag over the shoulder I of the margin. If partially filled, air in the collapsible container is first expelled by the nurse squeezing the collapsible bag until the air is exhausted. In nursing, the baby must bite the nipple to open the orifice I and suck the food out through the nipple, and as before stated, if the baby gulps wind while holding the nipple collapsed, air can not pass back from the nipple into the container 4 so that at no time is there any appreciable amount of air in the container, and the container collapses as the food is drawn therefrom. The baby can be nursed, or assisted in nursing, by squeezing the collapsible bag. Also, because of the collapsible bag, or container, the baby may manipulate the collapsible container in much the same manner that a baby manipulates the mothers breast in natural nursing. When the container is used without an outer container or bottle I6, the stiffening member I2 holds the collapsible sack from bending to such an extent as to close the inlet end of the nipple.
What I claim is:
l. A baby nurser comprising a nipple having an inlet at its inner end and an outlet at its outer end, and an automatically collapsible container, the nipple having a plug portion extending into and snugly fitting the mouth of the container, whereby the container is attached to the plug portion, and the plug portion extends partly into the container, and a projection attached to the nipple and extending therefrom lengthwise of the container within the same for preventing the container from folding over the inlet of the nipple.
2. A baby nurser comprising anipple having an inlet at its inner end and an outlet at its outer end, and an automatically collapsible container, the nipple having a plug portion extending into and snugly fitting the mouth of the container, whereby the container is attached to the plug portion, and the plug portion extends partly into the container, and a projection attached to the nipple and extending therefrom lengthwise of the container within the same for preventing the container from folding over the inlet of the nipple,
said projection comprising a tubular portion ex tending into the inner end of the nipple, the passage of the tubular portion forming the inlet for the nipple.
