NURSER PACKAGE Filed Oct. 11, 1967 INVENTORS W.J. EMERSON W.C. Ll NAM M 4- A TTORNEYS United States Patent Ofice NURSER PACKAGE William J. Emerson, Bartlesville, Okla., and William C. Linam, Chicago, Ill., assignors to Phillips Petroleum Company, a corporation of Delaware Filed Oct. 11, 1967, Ser. No. 674,618 Int. Cl. A6lj 9/00 U.S. Cl. 99-171 6 Claims ABSTRACT OF THE DISCLOSURE An infant nurser has an annular ring with a supporting structure, for instance, a depending loop integrally attached thereto; an open mouth plastic bag is sealed at the opening thereof to said annular ring; the bag is filled with a consumable liquid and a nipple is aflixed over the annular ring, a plastic film, for example, across the nipple or over the opening at the annular ring seals the liquid in the nurser. In one embodiment, means are also provided for breaking the thermoplastic film across the annular ring when access to the contents of the bag is desired.

BACKGROUND OF THE INVENTION This invention relates to disposable nursers for infants.

Many nursers containing prepackaged milk have been devised. A popular dispensing nurser employs a bottle whose neck opening is the size of a standard cap and nipple. To use this nurser the nipple is attached to the bottle. This nurser requires the user to sterilize the nipples before they can be used and in the case of glass bottles it is rather expensive.

Other nursers have been proposed for home use. For example, Boynton et al. 3,204,855 discloses a disposable nurser in which a flexible, collapsible bag is made from thin gauge plastic and placed in a bottle-supporting structure to which it is held in place by means of a cap. This nurser is intended for filling at home as contrasted with a prepackage container.

Prepackaged nursers have gained increasing popularity. These prepackaged nursers must provide a hermetically sealed package with a sterile enclosed nipple. Some of the more popular nursers supply flexible bags which collapse as the product is consumed. Some of these nursers provide a nipple which is unattached to the bottle opening itself but is supplied to the opening after the package has been opened. Others have a nipple over the bottle opening and an easily breakable sealed film between the contents of the package and the nipple over the normal opening of the nursing bottle. The sealed film prevents the contents of the package from leaking through the nipple.

Fischer 3,193,125 discloses a container in which a preformed thermoplastic nipple is attached to the top of a flat thermoplastic container. A hole is made in the nipple for use. The nipple and container can be made in one piece with the shape of the container relatively flat.

SUMMARY OF THE INVENTION It is an object of this invention to provide a disposable nursing package which is self-supporting and light weight.

It is a further object of this invention to provide a nursing container for prepackaged liquids in which the container contents are easily dispensed.

It is a still further object of this invention to provide a nursing container for prepackaged liquids in which a container means is provided for holding the container during dispensing thereof.

It is yet a further object of this invention to provide a nursing container which is easily fabricated.

According to the invention, a disposable infant nurser is provided comprising an annular ring with a depending 3,523,026 Patented Aug. 4, 1970 supporting structure affixed thereto. An open mouth plastic bag fits over said supporting structure and is sealed at the opening thereof to said annular ring. The bag is filled with a consumable liquid and a nipple is placed over the opening in the annular ring. A sealing film can be applied either under the nipple or over the nipple to pre vent the contents of the liquid from leakin out of the package prior to consumption.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawing forming a part hereof in which like reference characters depict like parts in all views, FIG. 1 is a sectional view through one embodiment of the invention; FIG. 2 is a view along lines 22 of FIG. 1; and FIG. 3 is a sectional view of a second embodiment of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The annular ring with the depending supporting structure can be molded from any suitable thermoplastic material such as solid polymers of at least one mono-l-olefin, said l-olefin having from 2-8 carbon atoms per molecule (that is, polymers and copolymers of these l-olefins), polyvinylchloride, polystyrene, and the like. The preferred ring materials are polymers of at least one l-olefin selected from the group consisting of ethylene, propylene, and butene. A preferable method of forming the annular ring and depending supporting structure is by injection mold ing. The open mouth bag is preferably formed of a thin gauge thermoplastic material which is relatively sturdy. The thermoplastic film can be a polymer of at least one 1- olefin selected from the group consisting of ethylene, propylene, and butene, polyvinylchloride, polyvinylidene chloride or copolymers thereof. A preferred material is a polyethylene (or ethylene/butene copolymer) bag having a coating on the outer surface thereof of a vinylidene chloride polymer (by vinylidene chloride polymr is meant polyvinylidene chloride and copolymers of vinylidene chlorid with vinyl chloride). The term annular ring as used throughout the specification and the claims is, of course, intended to include oval, rectangular and other similar geometric shapes.

The sealing film can be made of the same materials as the bag or from different materials. Preferably, the sealing film will be thinner and more easily breakable. A preferred film is polyvinylidene chloride coated polyolefin fi m.

The film piercing means such as that shown in FIGS. 1 and 2 is preferably made by injection molding a thermoplastic resin such as polyethylene, polypropylene, polybutene-l, polystyrene, polyvinylchloride and copolymers thereof. This piercing means can be omitted and the sealing film ruptured by depressing a portion of the nipple with a finger.

The nipple used in the invention can be made of rubber or thermoplastic material. Preferably, the nipple is made from a thermoplastic material and is injection molded or is vacuum formed. The thermoplastic materials are preferred since they are less expensive than rubber. It may be heat sealed to the annular ring or where film is sealed across the ring it may be snapped on.

As can be seen from the foregoing, a simple, effective and inexpensive dispensing package for infants is provided. The package is, in all respects, an easy one to manipulate during the dispensing of the contents therefrom whether the dispenser is held by the parent or by the infant.

The container can be filled through the top prior to afiixing the nipple or the bottom can be left open and the container filled through the bottom after the sealing film and nipple are in place, the bottom thereafter being sealed.

Referring now to FIGS. 1 and 2 in particular, a molded thermoplastic annular ring 2 with depending annular flange 3 has integrally molded thereto depending U-shaped loop or rib 4 which serves as a supporting structure. An open mouth thermoplastic bag 6 is heat sealed at the open mouth thereof to the annular ring 2 along line 7. The bag is filled with a consumable liquid, such as milk; and, according to one embodiment of the invention, a thin sealing film 8 is heat sealed over the open portion of the bag to annular ring 2 along line 9. A nipple 12 is sealed to the top portion of the annular ring 2 along line 13 and nipple 12 is provided with at least one opening 14 for removing liquid from the package. Beneath nipple 12 and above film 8 there is provided a means 16 with depending prongs 20 for breaking fihn 8.

As can be seen from FIGS. 1 and 2, the depending ribs 4 provide support for bag 6 and also provide a means by which the package can be gripped during the consumption of the liquid within the container. Further, the depending ribs 4 prevent free rolling of the package when placed on its side. The internal stiffening ribs 4 provide a means to hold the package as the bag 6 is being deflated by consumption. The positioning of the ribs 4 inside the bag maintains the bag 6 in the proper position during dispensing. If the rib were on the outside of the bag, it would not support the bag without a more substantial structure or without sealing the lower portion of bag 6 to the lower portion of rib 4. Also this construction makes possible high speed fabrication of the container with a minimum of steps which is absolutely essential to a commercially acceptable disposable package. Because there is no external supporting structure in the way, the heat sealing of the film to the ring is facilitated; this is because the bag can be sealed to the ring from the outside instead of from the inside which is more difiicult. It is also within the scope of the invention to form the nipple, annular ring and supporting loop as one integral piece. In such embodiments the sealing film as shown in FIGS. 1 and 2 would be sealed to the underside of the ring.

Referring now to FIG. 3, a similar nursing package has been provided with an annular ring 32 which has a depending annular fiange 33 at the lower portion thereof; in addition a rim 34 at the upper portion thereof is provided. In this embodiment the nipple 12' is clamped over rim 34 and the sealing film 36 is heat sealed over nipple 12' at 38. Also a handle structure 40 comprising at least one protuberance extending outwardly from ring 32 is provided to serve as another means for the infant to hold the nurser.

Example A tubular bag, heat sealed at the bottom and open at the top was formed of a laminate of 0.92 density (ASTM D 1505-63T) polyethylene and Saran (trademark for vinylidine chloride polymers). Each layer was 1 mil thick for a total laminate thickness of two mils. An annular ring with an integral depending U-shaped loop was fabricated from 0.950 density (ASTM D 1505-63T) 0.3 melt index (ASTM D 1238-62T, Condition E) ethylene-butene copolymer. The bag was drawn up around the depending loop and sealed to the annular ring. The polyethylene layer was on the inside so as to effect a good seal with the polyethylene ring. The bag was filled from the top with liquid and a film of the above-described laminate sealed across the opening of said annularring, again with the polyethylene layer in contact with the ring. A rubber nipple'was then 'aflixed to the ring.

While this invention has been described in detail for the purpose of illustration it is not to be construed as limited thereby but is intended to cover all changes and modifications within the spirit and scope thereof.

We claim:

1. A dispensing package comprising:

an annular ring with a supporting structure afiixed thereto;
