RELATED APPLICATIONS
There are currently no applications co-pending with the present application.
FIELD OF THE INVENTION
The present invention relates generally to infant bottles, and in particular, to infant bottles which include a mechanism for reducing the presence of air inside the liner of the bottle.
BACKGROUND OF THE INVENTION
Infant bottles are well known for feeding infants and toddlers. Many infant bottles include a liner to provide trouble-free cleanup. The liners normally obtain air pockets within the empty space which forms between the underside of the nipple and the top surface of the liquid, even if fully filled. As a result, the baby tends to ingest the air from the bottle, creating the need for the parent to perform excessive burping operations.
Various attempts have been made to provide a bottle with air displacement means. Examples of these attempts can be seen by reference to several U.S. patents. U.S. Pat. No. 5,033,631, issued in the name of Nightingale, describes a device for expelling air from a liner in a baby bottle.
U.S. Pat. No. 5,524,783, issued in the name of Popoff, describes a device for expelling air from a liner in a baby bottle.
U.S. Pat. No. 5,687,861, issued in the name of Wiedemann, describes a compressible baby bottle.
While these devices fulfill their respective, particular objectives, each of these references suffer from one (1) or more disadvantages. Many are not suited to release enough of the air pockets. While others infant bottles with a displacement means are not use friendly. Accordingly, there exists a need for bottle with air displacement means without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need.

However, the invention is not limited to the described embodiment, and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
The present invention describes a bottle with volumetric displacement means (herein described as the “apparatus”) 10, which provides a baby feeding bottle 20 which utilizes a disposable collapsible insert 38 with an integral mechanism to compress a bottom portion of said collapsible insert 38, thereby reducing a volume of air inside. Said collapsing mechanism is integral to a cylindrical body portion 22 of the apparatus 10 and further comprises a pair of opposed locking buttons 28 which allow a user to incrementally elevate an internal adjustable platform 26 which drives the collapsible insert 38 upwardly, thereby forcing excess air within said collapsible insert 38 out of the nipple 60 prior to consumption of the contained liquid 15. The apparatus 10 further comprises conventional and expected portions including a cylindrical bottle body 22, a nipple 60, an attachment ring 70, and a sanitary cover cap 80.
Referring now to FIGS. 1 and 2, front perspective and exploded views of the apparatus 10, according to a preferred embodiment of the present invention, are disclosed. The apparatus 10 comprises a bottle assembly 20, a collapsible insert 38, a nipple 60, an attachment ring 70, and a cap 80. The bottle assembly portion 20 of the apparatus 10 further comprises a transparent cylindrical bottle body 22 providing easy visual communication of a remaining volume of contained liquid 15 via molded-in and/or painted graduation markings 34 along an outer side surface. Said bottle assembly 20 also provides a vertically adjustable platform 26 onto which the collapsible insert 38 rests. Said adjustable platform 26 provides a means to compress the collapsible insert 38 as it is incrementally raised above an integral protective plastic base portion 24 of said bottle assembly 20. Said adjustable platform 26 is vertically positioned and locked in place via mechanical communication with a pair of opposing locking buttons 28 which are spring-biased outwardly through respective slot portions 30 formed within side surfaces of the bottle body 22. As a user presses both locking buttons 28 inwardly, the adjustable platform 26 is free to move vertically to expel air from the collapsible insert 38 or return to a bottom start position, respectively. The adjustable platform 26 comprises an upwardly domed profile which matches that of the nipple 60 so as to more completely displace the collapsable insert 38 as well as the contained liquid 15. The adjustable platform 26 may be secured at a desired height by vertically positioning and releasing the locking buttons 28. Each locking button 28 in turn mechanically engages a pair of locking apertures 32 being correspondingly formed within a wall portion of said bottle body 22. Said locking apertures 32 are arranged in two (2) parallel vertical rows on each side of said slot portion 30 (see FIGS. 3,4, and 5).
The collapsible insert 38 provides a cylindrical collapsing structure having a first insert flange 39 along an upper perimeter edge which collapses during feeding an infant the contained liquid 15 in a similar manner as PLAYTEX DROP-INS®. The nipple 60 further comprises a conventional design having a perimeter nipple flange 62 and an upwardly protruding nipple orifice 64. The attachment ring 70 further comprises an internal female threaded portion 72 and an ergonomic gripping surface 74 along a perimeter outer surface. The apparatus 10 is envisioned to be made of transparent or translucent food-grade plastic materials and introduced in a variety of attractive colors. Furthermore, the apparatus 10 is envisioned being made available having various internal fluid volumes such as, but not limited to: six (6), eight (8), and twelve (12) ounces.
Assembly of the apparatus 10 is accomplished by inserting the collapsible insert 38 into an inner cavity portion 25 of the bottle body 22 so as to cause the first insert flange 39 to rest upon a male threaded portion 23 of said bottle body 22. The nipple flange portion 62 of the nipple 60 is subsequently stacked upon said first insert flange 39 and the female threaded portion 72 of the attachment ring 70 is threadingly engaged and tightened against the corresponding male threaded portion 23 of the bottle body 22 to seal the bottle body 22, collapsible insert 38, and nipple 60 to each other. The cap 80 comprises a conventional dome-shaped snap-on protective device when the apparatus 10 is not in use which engages an outer surface of the attachment ring 70 via a friction fit.
Referring now to FIGS. 3, 4, and 5, close-up and section views of the bottle assembly portion 20 of the apparatus 10, according to a preferred embodiment of the present invention, are disclosed. The apparatus 10 provides a mechanism to position and secure the adjustable platform 26 at a desired vertical location via the two (2) locking buttons 28. Each locking button 28 further comprises a pair of integral locking posts 40 being formed along inwardly-facing side surfaces in a “U”-shaped manner and having cylindrically-shaped end portions which are correspondingly positioned to insertingly engage respective locking aperture portions 32 formed within an internal surface of the bottle body 22 and being arranged along both side edges of the aforementioned slot 30.
The locking buttons 28 supported and adjust the adjustable platform 26. Said adjustable platform 26 comprises a circular-shaped disc-like member having a diameter slightly less than an inner diameter of the bottle body 22, thereby forming a plunger-like mechanism. Said adjustable platform 26 further comprises a subjacent and indented circular platform support member 52 which provides an attachment means to the locking buttons 28 via respective outwardly extending spring posts 54. Said spring posts 54 comprise integrally-molded cylindrical appendages which extend outwardly from side surfaces of the platform support member 52. Said spring posts 54 are slidingly inserted into respective guide aperture portions 42 within each locking button 28. Said spring posts 54 are further encompassed by respective compression springs 56 which act against said locking buttons 28 to bias said locking buttons 28 in an outward direction, thereby causing the aforementioned locking posts 40 to forceably engage respective locking apertures 32.
Referring now to FIG. 6, a front perspective view of the cup insert 102, according to an alternate method of use of the invention, is disclosed. The cup insert 102 comprises a semi-rigid cylindrical body member with an open top designed to maintain a cylindrical shape during feeding of a contained liquid 15. Said cup insert 102 further comprises an upper perimeter second insert flange 104 which provides a sealing means similar to the previously described first insert flange 39. The cup insert 102 may be utilized in lieu of the previously described collapsible insert 38 upon such time as an infant no longer requires the collapsing function of the collapsible insert 38. Said cup insert 102 comprises a cylindrical shape having an outer diameter which may be slidingly inserted into an inner cavity portion 25 of the bottle body 22 such that the second insert flange 104 rests upon the male threaded portion 23 of said bottle body 22. Subsequently, the nipple 60 and attachment ring 70 are affixed in a conventional manner.
It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The preferred embodiment of the present invention can be utilized by the common user in a simple and effortless manner with little or no training. After initial purchase or acquisition of the apparatus 10, it would be installed as indicated in FIG. 1.
The method of configuring and utilizing the preferred embodiment of the apparatus 10 may be achieved by performing the following steps: procuring a model of the apparatus 10 having a desired fluid volume and color; removing the attachment ring 70 and nipple 60, if previously installed; inserting the collapsible insert 38 into the inner cavity portion 25 of the bottle body 22 until the first insert flange 39 is resting on the male threaded portion 23 of the bottle body 22; filling the collapsible insert 38 with a liquid beverage 15; threadingly installing the nipple 60 and attachment ring 70 in a conventional manner; holding the apparatus 10 vertically with the nipple 60 pointing in an upward direction; depressing both locking buttons 28 to operably motion the adjustable platform 26 upwardly in a plunger-like manner to force a desired amount of air from the collapsible insert 38 and out the nipple orifice portion 64 of the nipple 60 prior to feeding; feeding the liquid 15 to the infant in a conventional manner; preventing air pockets from re-forming within the collapsible insert 38 as a vacuum created inside said collapsible insert 38 causes said collapsible insert 38 to collapse; and, preventing a child from ingesting excessive air during feeding using the present invention 10.
The alternate method of use provides feeding of a maturing infant using an internal cup structure 102 at such time the infant progresses beyond a need for the air reduction function of the collapsing insert 38. The method of configuring and utilizing the cup insert 102 may be achieved by performing the following steps: inserting the semi-rigid cup insert 102 into the inner cavity portion 25 of the bottle body 22 in lieu of the collapsible insert 38; filling the cup insert 102 with a desired liquid 15 beverage; threadingly installing the nipple 60 and attachment ring 70 in a conventional manner; feeding the liquid 15 to the infant in a conventional manner.
