Lowrance  Inventor: Benjamin T. l-lowland, 5128 Assistant Exami'ler A"an Shoal) Hayter Avenue Lakewood Calm Attorney-Francis X. Lolacono, Sr. 90712  Filed: Sept. 3, 1971  ABSTRACT App]. No.: 177,606
US. Cl. 215/11 R, 215/11 C, 99/171 ND There is herein disclosed a baby bottle that is adapted to be vacuum sealed having a main body formed as a bottle to receive liquid therein, the body being provided at its upper end with external threads and a removable scaled membrane which is adapted with a pull tab for removal from the main body. A cap is threadably secured to the external threads and is provided with an enlarged central opening therein to removably receive a nipple which is used by a baby for sucking the liquid out of the bottle when the membrane is removed therefrom. To protect the sterilized nipple from contamination, there is also included a sealed cover which is readily removed when the bottle is to be used.
6 Claims, 4 Drawing Figures DISPOSABLE BABY BOTTLE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a baby bottle and more particularly to a disposable baby bottle that is pre-filled, sterilized and sealed.
2. Description of the Prior Art As is well known in the art, various problems and difficulties have been encountered in providing babies with proper feeding by means of bottles, wherein bottles and their associated parts, as well as the contents, should at all times be kept clean and sterilized. When a babys feeding time arrives and he is being cared for at home the problem is, naturally, under control. However, when the parents travel, visit, or for some other reason leave home, with the infant, feeding can then become more complicated. Generally, the bottles are prepared and sterilized at home, which takes considerable time, and then are packed in a bag or traveling case used for that purpose, during which time the nippics are exposed to various contaminants. Also, perhaps not enough bottles have been prepared and the supply runs out, causing a stop at the nearest restaurant or grocery store to have the bottles refilled, usually without the time or facilities for sterilization which all parents like to maintain.
Even with the advent of throw-away bottles, the problem of running out of sterilized milk or other sterilized liquids, such as formula, orange juice or plain water, still persists.
To the applicants knowledge, there is no throw-away baby bottle available on the market today that can provide sterilized parts as well as sterilized food in one package, wherein the bottle is pre-filled with any selection of liquids under ultimate, positive sterilized conditions, sealed and stored in such a manner as to maintain sterilization until said bottle is put into use.
SUMMARY OF THE INVENTION The present invention discloses a device for containing sterilized liquids for babies under positive, constant, sterilized conditions prior to use. This device comprises a disposable baby bottle unit having a main hollow body formed as a bottle or container to receive various liquids therein, under sterilized conditions, which are to be consumed by babies. The upper neck portion of the container is provided with external threads and is sealed by a thin membrane, preferably of the same material as the container. This material can be made from either plastic or very thin aluminum. Secured to this membrane is a pull tab whereby the membrane can be removed from the container, thereby providing an opening or outlet for the liquid therein. Included as part of the baby bottle, there is provided a screw cap having a central enlarged opening therein for reception of a sterilized baby nipple which is removably secured within the opening. In order to protect the cap and nipple from contamination at all times prior to use, there is a cover which is removably secured and sealed over both the cap and nipple. Said cover is removable at the time the baby is to be fed and capable of being snapped back into place if the content of the bottle is not completely emptied.
It is contemplated that such disposable, pre-filled baby bottles will be obtainable over the counter at stores, in supennarkets, or dispensed by vending machines that are capable of heating the liquids to a predetermined temperature.
OBJECTS AND ADVANTAGES OF THE INVENTION The present invention has for an important object a provision whereby a baby bottle is pre-filled under a sterilized condition, and is capable of being kept in such a condition under various situations prior to its first use.
Another object of the present invention is to provide a sterilized baby bottle that is vacuum sealed and is capable of being used at will by removing a sealed membrane providing said vacuum seal.
It is another object of the present invention to provide a sterilized, disposable baby bottle having a sterilized nipple under a protective seal and ready for use.
A further object of the present invention is to provide a sterilized, disposable baby bottle that is capable of storing various kinds of sterilized liquids under a vacuum seal by means of a removable membrane.
It is still another object of the present invention to provide a baby bottle of this character that can be shelf stocked in all markets or sold from vending machines.
It is a further object of the present invention to provide a sterilized, pre-filled, disposable baby bottle that is relatively inexpensive to manufacture.
It is still a further object of the invention to provide a device of this character that can be produced in large quantities under strict sterilized conditions.
Still another object of the invention is to provide a device of this character that is simple, lightweight and rugged in construction.
Other characteristics, advantages and objects of this invention can be more readily appreciated from the following description and appended claims. When taken in conjunction with the accompanying drawings, this description forms a part of the specification wherein like references and characters designate corresponding parts in several views.
DESCRIPTION OF THE DRAWINGS DESCRIPTION OF THE PREFERRED EMBODIMENT Referring more particularly to the drawings, there is shown a device for containing sterilized liquids in a vacuum-sealed, sterilized bottle. This device comprises a disposable baby bottle unit, generally indicated at 10, having a main hollow body forming a container or bottle 12, said bottle being defined by a somewhat cylindrical thin wall 14 and a bottom wall 16 having the thickness of said wall 14. The upper end wall 18, which would be better defined as a thin membrane, is used to seal the sterilized liquid 20 within the sterilized bottle 12. It should be noted that the bottle could be formed from various types of plastic. However, a thin, lightweight metal such as aluminum is preferred.
The membrane 18 is provided with a pull tab 22 whereby said membrane can be easily removed and separated from the main body 12 by means of a scored, annular groove 24. That is, when pull tab 22 is lifted upwardly the membrane 18 will tear along the scored, annular groove 24, thereby defining an opening or outlet by which the liquid can flow from the container 12.
In addition, the upper portion of the container 12 is provided with external threads 25 which are used as a means for securing the cap 26 to the bottle when corresponding internal threads 27 of said cap are screwed thereon. The cap 26 also includes a central enlarged opening 28 defined by an annular, inwardly-projecting flange 30 which, in turn, forms an annular recess 32. Both the flange 30 and recess 32 provide means for removably attaching a nipple, generally indicated at 34. This nipple is of a conventional type comprising an enlarged annular flange 36 extending radially outwardly from the body portion 38, said flange being adapted to be received in said annular recess 32 of the cap 26. As the flange 36 extends outwardly there is formed a reduced-diameter, annular groove 40 in which flange 30 is received. When the nipple 34 is engaged within the cap 26, said nipple is locked into position as the cap is tightly screwed to the bottle 12.
In order to provide positive protection against contamination of the nipple 34 and cap 26, a cup-like cover, generally indicated at 42, is removably secured to the cap 26 by a radially-extending flange 44 which seats against the annular lip 45 of the lower portion of cap 26. Said flange 44 projects downwardly at 46, covering the annular edge 48. Thus, the cover 42 can be removed and replaced if the bottle is not completely emptied by the baby. However, it is contemplated that each bottle will be half the size of a normal baby bottle, allowing each bottle to be completely consumed after opening.
A LTERNATIVE EMBODIMENT Referring now to FIG. 4 in which an alternative embodiment is shown, this arrangement illustrates the cover 42 and cap 26 as being sealed simultaneously to the main body 12 by a thin sheet of plastic 50, or the like, that can be thermically sealed thereon. This insures that the cap cover cannot be inadvertantly removed without detection.
Also included in FIG. 4 is an alternative arrangement wherein the main body 12 is provided with an annular flange 52 that is sealed within groove 54 of extemallythreaded neck member 56 which comprises the means for sealing the bottle together with the removable membrane 58.
Further, said main body 12 can be formed of suitable, heat-resistant, plastic material, and said neck member 56 and membrane 58 can be formed of suitable metal, such as aluminum.
The invention and its attendant advantages will be understood from the foregoing description and it will be apparent that various changes may be made in the form, construction and arrangement of the parts of the invention without departing from the spirit and scope thereof or sacrificing its material advantages, the arrangement hereinbefore described being merely by way of example, and I do not wish to be restricted to the specific form shown or uses mentioned, except as defined in the accompanying claims.
