Definitions

  • This invention relates to a nursing apparatus, and more particularly, to disposable nursers having flexible liners or bottles.
  • U. S. Patent No. 3,161,311 issued to Frank Boston discloses a rubber band placed over the bottle holder which keeps the liner in place during filling and handling; however, the flexible bottle still passes between the screw threads which fasten the nipple to the bottle.
  • U. S. Patent No. 3,593,871 issued to Larry Bundy discloses a nipple which has been directly sealed to a bag, with both the nipple and the bag being dispos ⁇ able.
  • the bag is filled through a separate filler tube.
  • This solves the problems discussed above but provides a very inconvenient means for filling the bottle and a more expensive system.
  • ⁇ . S. Patent No. 2,599,630 issued to Emma Hair discloses a hard disposable container which may be held on a ring during the filling process, if the container is rigid enough. If the typical flexible bottle is used, it would be necessary to pass the open end of the bottle over the upper lip of this ring. This then places the liner between the threads of the ring and the nipple holding cap with all the same problems of slippage, tearing of the liner, and leakage, discussed above.
  • the present invention relates to a disposable nursing system that provides the benefits gained by the use of disposable flexible bottles and retains the benefits of the ease of handling provided by the hard nondisposable bottles.
  • the present invention firmly clamps the flexible bottle within the bottle holder so that the bottle can be filled without fear of the flexible bottle's slipping, causing spillage and contamination.
  • Such a system will also permit placing of the bottle within a microwave for heating without having to attach a lid to hold the flexible bottle in place. Sealing a lid to the flexible bottle could cause excessive pressure build-up and an explosion during the heating process.
  • the disposable nurser of this invention comprises a bottle holder, a countercap which is slidably mounted on the bottle holder, a nipple, and a nipple holding cap in which the nipple may be mounted.
  • the bottle holder is comprised of a hollow frustum that is open at both ends with one end thus having a larger circumference than the other end.
  • a plastic liner, denominated flexible "bottle" by the industry, is inserted within the bottle holder such that the open end of the flexible bottle is pulled back over the upper lip of the larger end of the bottle holder and downward along the exterior of the bottle holder.
  • the countercap comprising a sleeve in which one end has a greater circumference than the other end, is so sized and configured that the large end of the sleeve may be slidably mounted over the smaller end of the bottle holder.
  • the countercap may then be slid upward over the open end of the flexible bottle until a stop means is engaged, which prevents the countercap from advancing any further.
  • a nipple may be removably mounted within a nipple holding cap which then may be removably attached to the larger end of the countercap, which results in the nipple's being connected to the larger end of the bottle holder and being removably sealed in liquid flow relationship with the flexible bottle.
  • the invention accordingly comprises an article of manufacture possessing the features, properties and the relation of elements which will be exemplified in the article hereinafter described, and the scope of the invention will be indicated in the claims.
  • FIGURE 1 is a front elevation, half of which is broken away to show a cross section of the disposable nurser
  • FIGURE 2 is a detail of the front elevation of the disposable nurser.
  • the disposable nurser is generally indicated as 10 in the views of Figs. 1 and 2. Referring to Figs. 1 and 2, it can be seen that the disposable nurser 10 comprises a nipple 12, a nipple holding cap 14, a countercap 16, a bottle holder 18, and a flexible bottle 20.
  • the bottle holder 18 is comprised of a hollow frustum having a first end 22 and a second end 24, both of the ends being open.
  • the hollow frustum includes those frustums whose vertex is at an infinite distance from the base, which would include a general ⁇ ly cylindrical configuration.
  • the preferred embodi- ment incorporates a hollow frustum with a finite vertex.
  • the bottle holder 18 also has a first portion 26 and a second portion 28.
  • the circumference of the exterior surface 30 of the bottle holder 18 is greater around the first portion 26 of the bottle holder 18 than the circumference around the second portion 28 of the bottle holder 18, defining an annular shoulder 32 interposed between the first portion 26 and the second portion 28 of the bottle holder 18.
  • the flexible bottle 20 has an open end 34 and a closed end 36.
  • the flexible bottle can also be considered to have a first part 38, which includes the open end and a second part 40 which includes the closed end 36.
  • the second part 40 of the bottle 20 is inserted within the bottle holder 18 so that the closed end 36 of the bottle 20 is proximal to the second end 24 of the bottle holder 18.
  • the first part 38 of the flexible bottle 20 is extended beyond the first end 22 of the bottle holder 18, is then turned downward over the top edge 42 of the bottle holder 18, thus lying between the top edge 42 and the nipple 12, and then along the exterior surface 30 of the bottle holder 18.
  • the open end 34 of the flexible bottle 20 may be comprised of a pair of tabs 35 which may be perforated as at 37 for easy removal later.
  • the countercap 16 comprises a sleeve having an exterior surface 44 and an interior surface 46, a first end 48 and a second end 50, and a first section 52 and a second section 54.
  • the first section of the countercap 52 has an interior circumference greater than the interior circumference of the second section 54, thus defining an annular shoulder 56 interposed between the first section 52 and the second section 54 of the countercap 16.
  • the countercap 16 is so dimen ⁇ sioned and configured that it may be mounted on the bottle holder 18 by inserting the second end 24 of the bottle holder 18 into the first end 48 of the counter- cap 16 and then sliding the countercap 16 upward toward the first end 22 of the bottle holder 18.
  • the countercap 16 may be slid upward on the bottle holder 18 over the open end 34 of the flexible bottle 20 so that the first part 38 of the bottle 20 lies between the interior surfaces 46 of the countercap 16 and the exterior surfaces 30 of the bottle holder 18.
  • the countercap 16 and the bottle holder 18 are so configured that the annular shoulder 32 of the bottle holder 18 and the annular shoulder 56 of the countercap 16 are opposed and engage one another, creating a stop means, pre ⁇ venting the countercap 16 from advancing further up the bottle holder 18.
  • the stop means When the stop means is engaged, the first end 48 of the countercap 16 reaches a stop position 57 which is located intermediate the first end 22 and the second end 24 of the bottle holder 18.
  • the shoulder 32 of the bottle holder 18 may be located at any point interme ⁇ diate the first end 22 and the second end 24 of the bottle holder 18.
  • the opposing shoulders 32 and 56 are so located that the proper stop position 57 of the first end 48 of the countercap 16 is attained.
  • the stop position 57 of the first end 48 of the countercap 16 is proximal to said top edge 42 of the bottle holder 18 but the first end 48 of the counter- cap 16 does not contact the nipple 12.
  • the stop means as a pair of opposing annular shoulders 32 and 56
  • the exterior surface 30 may have a gradually increasing circum ⁇ ference and that the countercap 16 may be designed to have a similar slope to its interior surface 46. If the bottle holder 18 and the countercap 16 are so dimensioned, a friction stop will result as the countercap is slid upward on the bottle holder 18 toward the first end 22 of the bottle holder 18. It would also be a matter of design choice to use other types of interlocking protrusions on the interior surface 46 of the countercap and the exterior surface 30 of the bottle holder 18 to provide a stop means.
  • a protrusion 58 is shown located on the interior surface 46 of the first section 52 of the countercap 18.
  • This protrusion 58 in the preferred embodiment is shown as a ridge type structure but may take any number of different configurations, includ ⁇ ing, but not necessarily limited to, nubs, a series of ridges, and so forth.
  • three of these protrusions 58 are used as a means of controlling the tightness of the fit between the first section 52 of the countercap 16 and the first portion 26 of the bottle holder 18, which permits a fit tight enough to resist downward slippage of the countercap 16 and yet permit easy intentional removal of the countercap 16.
  • nipple 12 is inserted within the nipple holding cap 14.
  • the nipple holding cap 14 may then be removably attached to the countercap 16 by an attach ⁇ ing means which may be any of those means well known in the art.
  • nipple holding cap 14 has a set of screw threads 60 formed on its interior surface, and screw threads 62 are formed about the exterior surface 44 of the countercap 16 proximal to the first end 48 of the countercap 16.
  • the screw threads 60 of the nipple holding cap 14 may be removably engaged with the screw threads 62 of the countercap 16 causing the nipple 12 to be sealingly connected to the top edge 42 of the bottle holder 18.
  • nipple 12 and the nipple holding cap 14 are further shown and described in my co-pending application serial number 07/345,723 which was filed on June 2, 1989, which description is incorporated herein by reference.
  • all the parts, with the exception of the nipple, which is constructed of latex rubber, are formed of plastic material.
  • the disposable nurser may be made from any suitable materials. Having thus set forth a preferred construction for the disposable nurser 10 of this invention, it is to be remembered that this is but a preferred embodi ⁇ ment. Attention is now invited to a description of the use of the disposable nurser 10.
  • the parts of the disposable nurser 10 are disas ⁇ muld and cleaned prior to the next use with the nipple 12 generally being the only part requiring sterilization.
  • a sterile flexible bottle is inserted within the bottle holder 18 so that the closed end 36 of the flexible bottle is proximal to the second end 24 of the bottle holder.
  • the open end 34 of the flexible bottle 20 is separated and pulled downward by its tabs 35 over the top edge 42 of the bottle holder 18 and downward along the exterior surface 30 of the bottle holder 18.
  • the countercap 16 is mounted over the second end 24 of the bottle holder 18 and slid upward along the bottle holder 18 passing over the first part 38 of the bottle 20 such that the open end 34 of the bottle 20 extends downward below the second end 50 of the countercap 16.
  • the countercap 16 is pushed to the stop position 57 such that the annular shoulder 32 of the bottle holder 18 and the opposing annular shoulder 56 of the countercap 16 are engaged and the first part 38 of the bottle 20 is pinched and held between the opposing shoulders.
  • the protruding ridge 58 provides a friction fit between the countercap 16 and the bottle holder 18 resisting downward movement by the countercap 16.
  • Milk or other fluids may now be poured into the flexible bottle 20 and, if desired, the fluid may be heated in a microwave without risk of a buildup of pressure or risk of the flexible bottle 20 sliding free.
  • the nipple 12 is placed within the nipple holding cap 14, which is then removably attached to the countercap 16.
  • the nipple 12 is sealingly attached to the flexible bottle 20 and a fluid flow relationship will exist between the nipple 12 and the flexible bottle 20.
  • the tabs 35 may be removed along their perforations 37 so that the first part 38 of the bottle 20 now ends 39 at a point generally adjacent to the second end 50 of the countercap 16.
  • the disposable nurser 10 is now ready for use.
