This invention relates to a nursing unit, and more particularly to a disposable feeding bottle for babies. I l I The object of the invention is to provide a disposable feeding bottle for babies which includes a replaceable throw-away container and a rigid rim andcap, the container adapted to be thrown away after each feeding and replaced by a new, sanitary, replaceable container. A further object of the invention is to provide a disposable feeding bottle for babies which includes a throw-away container of a shape so that it can be stacked one within another, the assembled feeding bottles being arranged so that the parts will not accidentally separate and wherein a fluid-tight joint is provided.
A still further object of the invention is to provide a disposable feeding bottle for babies which is extremely simple and inexpensive to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings forming a part of this application, and in which like numerals are used to designate like parts throughout the same:
Figure 1, which is the single figure, is a side elevational view of the feeding bottle of the present invention, with parts broken away and in section.
Referring in detail to the drawing, the numeral I designates the container which may be fabricated of any suitable material, such as waterproof paper or cardboard, the container I0 being conical in shape and proportioned so that it is of the wide-mouth type which is slightly larger at the top than it is at the bottom. Thus, the containers I0 can be nested one within the other when the containers I0 are packed for shipment or storage. The container I0 includes the annular side wall II and a bottom wall I2. The container I0 further is provided with an annular downtumed flange I4 for a purpose to be later described.
The disposable feeding bottle of the present invention further includes an annular rim I5 which may be made of a suitable rigid plastic material, and the upper edge of the rim I5 is rounded, as shown at I6, so that the flange M of the container I0 can be pushed snugly down over the rim I5. The rim I5 is arranged in surrounding relation with respect to the upper surface of the container III. The rim I5 is further provided with a plurality of exterior threads I1,
and the bottom of the rim I5 is smooth, as at I 8, so as to facilitate the gripping or holding of the device when the unit is being sealed.
The assembly further includes a cap, which is indicated by the numeral I9, and the cap I9 may be fabricated of the same material as: the rim 15, the cap I9 being rigidly constructed of a suitable material, such as plastic. The cap I9 includes an annular collar or sleeve 20 which is threaded interiorly for a portion of itslength, and the sleeve 20 is adapted to be arranged in threaded engagement with the screw-threads I1 on the rim I5. Formed integrally with the top of the sleeve 20 or secured thereto is an annular ledge 2I which is provided with a downtumed annular lip 22 for a purpose to be later described.
There is further provided a nipple 243 which may be fabricated of any suitable flexible material, such as rubber. The nipple 23 includes a body portion 24 that terminates in a base 25, the base 25 including an arcuate or rounded portion 26 which is adapted to snugly engage the flange I4 on the container I0. The base 25 has its outer periphery thickened, as at 21, and thickened portion 2'! coacts with the remaining portion of the base to provide an annular groove or recess 28 which receives therein the downwardly extending lip 22 of the ledge 2|. Thus, there will be no possibility of the nipple 23 being accidentally pulled out or disengaged from the rest of the unit. The cap I9 is provided with a central opening or hole 29 through which the body portion 24 of the nipple 23 projects.
In use, the rim I5 is arranged in surrounding relation with respect to the upper end of the container I 0, the upper rounded surface I6 of the rim I5 engaging the rounded flange I4. Then, the nipple 23 is arranged so that the concave or rounded surface 26 on its base engages the flange I4, and next the cap I9 is screwed onto the screw-threads I! of the rim I5. It will be seen that the downwardly extending lip 22 of the cap I9 will seat in the groove 28 so that the nipple 23 cannot be accidentally pulled loose from the rest of the unit. Also, this will result in a fluid tight seal being provided.
The container I0 can be manufactured in any suitable manner, so that the resulting container will have a small cost, and the nipple may be made of rubber. When the cap I9 is screwed in place, it will bring sufi'icient pressure on the base of the nipple and on the flange I4 of the container ID to hold the nipple in place and make a water-tight joint.
The container III has a closed bottom and the entire unit consists of four parts. The bottom outside portion of the rim I5 is smooth, as at l8, this affording space whereby the rim may be held with the hands while the bottle is bein assembled and food placed therein. The feedin bottle of the present invention will provide a simple, practicable, disposable feeding unit that is easy to assemble for use and easy to disassemble after use. The warming of food may be accomplished by placing the feeding bottle in warm water, or other warming methods may vided with an annular downturned flange on its upper. end, said container .being of slightly greater diameter at:its top than at :its bottom, vsaidlcontainer including .a side wall and a bottom wall, an annular rim arranged in surrounding relation with respect to the uppey'exterior surface of said container and provided with an upper relative edge for engaging the lower surface Lot said .flange, said rim being provided with a plurality of spaced screw-threads on its exteiior surface, said rim having an interio conical r cutout for receiving said side wall, aicap including an interiorly threaded sleeve arranged in engagement with said screw-threads, there being a central op n n in the to of said cap, a ledge projecting inwardly from said sleeve and extending over said flange, and a flexible nipple having a base interposed between said flange and ledge, the lower portion of said rim being smooth, Said pple having a body portion projecting through the opening in said cap, said rim and cap being fabricated of a rigid material, the lower edge of said base'being concave and fitting over said flange, an annular lip extending downwardly from said ledge, said lip being arranged in spaced parallel relation with respect to said sleeve and being of less length than the latter,
"said base having its outer portion thickened and shaped to define an annular groove in the upper surface of the nipple base for receiving said lip.
