FIGURE 10 is an enlarged fragmentary view of the protruding nipple portion of the container means shown in FIGURE 6, and

FIGURE 11 is a sectional view taken on the line 11-11 of FIGURE 10.

Like reference numerals designate like parts throughout the several views.

Referring to the figures, the liquid dispensing means 10 embodying the invention comprises a container means 12 (FIGURE 6) of substantially rectangular configuration in its unfilled condition having front and rear side walls 14 and 16, with top and bottom portions 18 and 20.

The top portion 18 of the container means 12 is provided with a pair of foldable flaps 22, 24 formed by the side slits 26 along the side edges 28 of the container means 12. The bottom portion of the container means 12 has a left corner portion 30 for providing a nipple protuberance, while the right corner portion 32 has a sealed region 34 which does not communicate with the cavity 36 within the container means 12. The cavity 36 receives therein liquid through the opening 38 provided at the top portion 18 of the container means 12.

The container means 12 are disposable after each use of the dispensing means 10 and is removably received within and supported by the structure means 40 of the dispensing means 10. The structure means 40 is of tubular configuration providing an opening 42 extending through its top and bottom portions 44, 46 for receiving therein the container means 12. The container means 12 may readily be received through the opening 48 at the bottom of the structure means 40 or through the opening 50 at the top 44 of the structure means 40. As shown in FIG- URE 4, the flaps 22, 24 are folded apart over the top portion 44 of the structure means leaving the opening 38 into the cavity 36 of the container means 12 open for receiving liquid therethrough while positioned within the structure means 40. After filling the container means 12 with a liquid to the extent desired, the flaps 22, 24 of the container means 12 are brought together and folded together over one side 51 of the top portion 44 of the structure means 40 and secured thereallong by the clamp means 52 as clearly shown in FIGURE 3.

The clamping means 52 which may be of a spring-actuated type is releasable by compressing its ends 55, and when engaged as illustrated, clamps the outer structure means 40 with the top portion 18 of the container means 12 sealing the contents within the container means 12 while so positioning and retaining same within the opening 42 of the structure means 40. Of course, the container means 12 is rapidly released by the removal of the clamping means 52.

For further securing the container means 12 within the structure means 40, the bottom portion 46 of the structure means 40 is provided in its right corner portion 56 with a securing element 58 in the form of a clamping fastener having mating portions 60, 62 on opposite sides of the structure means 40. The corner portion 34 of the container means 12 is engaged by the portions 60, 62 of the securing element 58 as shown in FIGURE 5 for securely and releasably attaching the right corner portion of the container means 12 with the corresponding bottom portion of the structure means 40. Thus, the container means 12 is releasably secured at its top and bottom portions 18,

20 with the respective top and bottom portions 44, 46 of the structure means 40.

The bottom 46 of the structure means 40 is provided with a cutaway region at its left corner portion defined by the diagonal edges 64. The cutaway region of the bottom of the structure means 40 allows the left corner portion 30 of the container structure 12 to extend therefrom in exposed relationship. The portion 30 of the container means 12 provides a nipple protrusion 65 having an outer configuration provided by the internal fluid liquid pressure exerted by the liquid contained therewithin. The configuration produced is substantially of conical form and most suitable for feeding an infant or small child. The end 66 of the nipple protrusion 65 formed in the container means 12 may be provided with an opening therethrough 68 (see FIGURES l0 and 11) which may be sealed or enclosed by a removable adhesion strip or tab element 71 which can be removed just before the infant is to be fed by the liquid dispensing means 10.

Since the container means 12 is made of a thin plastic material which is highly deformable and the nipple protrusion 65 which is formed by such liquid pressure is readily deformed by the pressure or sucking action of an infant receiving the nipple protrusion in its mouth and in contact with its jaws, this structure minimizes any deformation or injury which might be caused by less deformable nipples now in general use. The deformation of the nipple protrusion 65 by the action of the infant does not result in increasing the pressure exerted on the infants tissues as the nipple protrusion 65 is compressed by the infants mouth because of the substantially constant pres sure exerted by the fluid rather than the properties of the material of which the nipple is composed. Thus, many serious ailments resulting from undesirable forces exerted upon the infants body during its exercise of the instinctive sucking and feeding action, whether known or unknown, is minimized by the deformable nature of the nipple protrusion of the means 10 with its low, substantially constant pressure exerted upon its deformation by the infant.

A cover means is received over the bottom portion 46 of the structure means 40 for closing and protecting the bottom portion 20 of the container means 12 when the means 10 is not being used for dispensing the liquid contained therein. When the means 10 is to be used, the cover means 70 which is slideably received over the bottom portion 46 of the structure means 40 is readily removed to expose the nipple protuberance 65. The cover means 70 as shown in FIGURE 7 may also be made of a plastic material providing side Walls 72 with ends 74, 76 which are open for allowing the removal or positioning of a new container means 12 within the structure means 40 through the bottom portion 46 without the removal of the closure means 70. In order to position the cover means 70 when secured over the bottom portion 46 of the structure means 40, the bottom portion 46 is provided with an outer dimension which is reduced with respect to the upper portion 44 to provide a shoulder 78 for abutment by the end 74 of the closure means 70, as clearly illustrated in FIGURE 3. When the cover means 70 is thus positioned, it provides a support for resting the means 10 in its upright position on a substantially horizontal surface as shown in FIGURE 3.

The cover means 70 is dimensioned, so that its upper end 74 may be received over the clamp 52 engaging the top portion 44 of the structure means 40 for supporting the means 10 in its inverted position with its nipple protuberance 65 of the bottom portion 20 of the container means 12 extending upwardly. Supporting the means 10 in this position, as shown in FIGURE 7, may be desirable during the feeding of an infant when such feeding is interrupted and before the container means 12 is to be discarded at the end of the feeding.

The closure means 70 illustrated in FIGURE 8 is of a modified form, having its end 76 enclosed by a bottom portion 80 for completely enclosing the exposed bottom portion 20 of the container means 12.

FIGURE 9 illustrates in detail the right corner portion 32 of the container means 12 which has a region 34 sealed along the line 80 for preventing liquid from being received within this region 34. Thus, the region 34 which is sealed may be clamped with the structure means 40 by the securing element 58 and avoids leakage should the container means 12 be punctured thereby, and also acts to prevent contamination of the fluid within the container means 12.

FIGURES 10 and 11 illustrate in detail the manner in which the removable strip or tab element 71 is positioned over the opening 68 in the end 66 of the nipple protrusion 65 and the arrow 82 illustrates the action by which the element 71 may readily be removed for uncovering the opening 68 and allowing liquid to be dispensed therethrough.

The liquid dispensing means 10 described in detail provides a device allowing the sanitary dispensing of liquid to infants and children by the use of a disposable container means 12 providing convenience to the user as well as highly sanitary conditions. The nipple protuberance formed and having its contour deformably maintained by the pressure of the liquid contained within the container means 12 also provides an important feature conducive to the health and well-being of the infants and young children using this device. The device may also be readily manufactured, is unbreakable in nature, highly useful when traveling, and provides liquid in a sanitary manner for an unlimited number of feedings by the use of the disposable container means 12.

It will, of course, be understood that the description and drawings, herein contained, are illustrative merely, and various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.
