Description

FIELD OF THE INVENTION

The present invention generally pertains to artificial, elastic teats used for feeding infants or babies. More specifically, the present invention relates to a stretchable teat composed of elastic materials, which can be readily adapted to fit and tightly seal a range of receptacles, regardless of their size and capacity.

BACKGROUND OF THE INVENTION

In a case where a mother does not breastfeed or is not present, the baby or the infant is usually fed with expressed breast milk, formulas or other liquids or solutions, using baby feed bottles. A typical bottle comprises an elongate, necked receptacle, containing fluid sustenance and a teat, consisting of a nipple and a collar. The teat is supposed to mimic as best as possible the natural structure and feel of the human breast, and is to be placed within the infant's mouth. The teat can be assembled to or disassembled from the vessel, which contains the feed. The conventional teats are made of elastomeric materials, such as silicone, latex or TPE, and have a passage and an opening through which the baby sucks the fluid.

Patent U.S. Pat. No. 6,871,751 describes a baby bottle nipple, comprising a sealing surface adapted to be fastened on a baby bottle.

Patent U.S. Pat. No. 8,528,756 discloses a leakproof closure sealing system for baby bottles comprising a lower and an upper closure rings and locking elements for fastening the feeding teat to the bottle.

The above referenced patents describe means for fastening an artificial teat to a feeding bottle, but they do not disclose a stretchable elastic teat, that is fitted over a range of commonly used containers.

Patent U.S. Pat. No. 5,673,806 discloses a teat for a baby's bottle, whose nipple is fitted with dynamic means designed to implement a spring effect to enable axial stretching of the nipple. Patent U.S. Pat. No. 5,673,806 describes a teat that can be extended vertically, but does not disclose a teat that stretches horizontally and therefore, can be placed over various available containers and receptacles.

Although baby bottles come in a variety of styles and shapes, the designated commercial bottles are relatively costly, they ought to be specifically purchased in great quantities and their narrow structure can make it difficult to properly clean and sterilize them.

In light of the above, there remains a long felt and unmet need to provide improved inexpensive teats for feeding infants and babies that can be used with a variety of available containers.

SUMMARY OF THE INVENTION

Reference is now made to FIGS. 14A and 14B which illustrate an example embodiment of the present invention. The elastic teat 100 comprising a nipple 101 for sucking liquid, an intermediate portion 102 and a stretchable lower portion 103, is fitted over a container 106 of choice and is tightly secured to it by a securing mechanism 200. In FIG. 14A the securing mechanism is in a locked state and in FIG. 14B the securing mechanism is in an unlocked state.

According to one embodiment, the securing mechanism is a band clamp 200 of generally circular shape having free ends 202U, 202L, with each of said free ends of the band clamp bent at right angles to the plane of the clamp. The band clamp may be a self-tightening spring band clamp where the diameter of the band is enlarged by squeezing the free ends 202U and 202L together (e.g., using a thumb and forefinger in a pincer grip).

In the example embodiment depicted in FIGS. 14A and 14B, the clamp is a band clamp with two arms 204, an upper arm 204U and a lower arm 204L. It is made clear that any configuration of the clamp, with any number of arms is considered to be within the scope of the invention.

Next to each protrusion is a valley or inlet 208 into which the opposing protrusion fits. In embodiments, in the resting, unlocked state of the clamp 200 the notches or protrusions 206 are separated from each other and it is necessary to push the bend ends away from each other in order to clasp the protrusions together.

In embodiments (not shown), there are more that one notch 206, to facilitate securing the teat to containers of various diameters.

While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications and other applications of the invention may be made. Therefore, the claimed invention as recited in the claims that follow is not limited to the embodiments described herein.
