DETAILED DESCRIPTION
(9) The following detailed description is directed to apparatus and methods for providing a feeding bottle that facilitates the feeding experience for both an infant and the care provider. As discussed briefly above, the transition from breastfeeding to bottle feeding can be frustrating for both the infant and the caregiver. Utilizing the concepts described herein, a feeding bottle includes a realistic nipple assembly that closely simulates the texture and feel of a human breast. In doing so, the infant is substantially more likely to correctly and quickly latch on to the bottle nipple. Other features of the feeding bottle according to various embodiments described below allows for a consistent flow of fluid, even when the infant is biting on the nipple. Still other features allow for simplified filling, closing, and holding the bottle by providing a wide, stable, and non-slip base.
(10) As used throughout this disclosure, the term infant may apply to any person of any age that may drink fluid from a bottle. The term fluid may be used to refer to any type of liquid that may be transferred from the bottle container to the infant via the bottle nipple. In the following detailed description, references are made to the accompanying drawings that form a part hereof, and which are shown by way of illustration, specific embodiments, or examples. Referring now to the drawings, in which like numerals represent like elements through the several figures, the feeding bottle will be described.

(13) As will be discussed in greater detail below, the nipple assembly 104 may have a texture gradient that changes from the end of the nipple to the base of the nipple assembly 104 proximate to the container 102. The texture of the nipple assembly 104 is yet another feature of the feeding bottle 100 that mimics a human breast to promote proper latching and to ease a child's transition from breastfeeding to bottle feeding. In addition, the nipple assembly 104 is a one-piece assembly that includes a rigid or semi-rigid locking ring configured to thread the nipple assembly 104 onto the container 102, and a silicone or otherwise pliable material overmolded onto the locking ring, creating an easy to use and easy to clean one-piece assembly.
(14) As seen in
(15) The detachable bottom 108 snaps into place as described below and may be manufactured from a non-slip material such as a thermoplastic elastomer, silicone, or the like. The non-slip material provides a source of frictional engagement with a surface on which the feeding bottle 100 is placed so that the caregiver can thread the nipple assembly 104 onto the container 102, fill the container 102, and clean the container 102 while the feeding bottle 100 remains in place and secure from slipping. This feature is advantageous when filling, using, or cleaning the feeding bottle 100 with one hand while holding the infant or being otherwise engaged with the other hand. According to various embodiments, the detachable bottom 108 may be manufactured in multiple colors. Because the detachable bottom 108 is easily removed and replaced on any container 102, the bottoms may be color coded and used to identify a particular child, a particular fluid, and/or a particular day or time that the feeding bottle 100 was filled or is to be consumed.
(16) Referring now to
(17) The container 102 includes a neck 304 to which the nipple assembly 104 is coupled. The neck 304 defines a fill aperture 318 through which the interior of the feeding bottle 100 may be filled with fluid. According to one embodiment, the neck 304 is configured at an offset angle 308 from horizontal that effectively tilts or angles the nipple assembly 104 with respect to the container 102. The offset angle 308 of the nipple assembly 104 provides a more natural and/or comfortable hand position for the caregiver when feeding an infant with the feeding bottle 100. For example, due to the offset angle 308, a caregiver may be able to rest his or her hand lightly on the infant's torso or on the caregiver's own body while holding the infant and the feeding bottle 100 in position for feeding. The feeding bottle 100 will be angled at a lower position during feeding than if the offset angle 308 did not exist, increasing the comfort of the caregiver and allowing for an unobstructed view of the infant during feeding. An example range of offset angles 308 includes, but is not limited to, 10 degrees to 25 degrees from horizontal, such as a 15 degree offset angle 308.
(18) The neck 304 includes neck threads 310 for coupling the container 102 to a nipple assembly 104 via corresponding threads on the nipple assembly 104. According to one embodiment, the neck threads 310 include a short pitch that allows the nipple assembly 104 to be screwed on or off with an approximate 120 degree rotation. Multiple vent notches 312 are positioned around the circumference of the neck 304. According to the example shown, there are four vent notches 312 molded into the neck 304, but it should be appreciated that a greater or fewer number of vent notches 312 may be used. In addition to the vent notches 312, there may be corresponding thread vents 314 that interrupt the neck threads 310 at appropriate positions proximate to the vent notches 312. The vent notches 312 and the thread vents 314 allow for the flow of air in and out of the feeding bottle 100 to equalize the pressure inside the container 102 and maintain adequate fluid flow through the nipple assembly 104. It should be appreciated that the size, shape, positioning, and quantity of the vent notches 312 and the thread vents 314 may be altered from what is shown in the various figures without departing from the scope of this disclosure. As one example, the vent notches 312 may be configured as apertures within the neck 304 instead of notches or depressions in the top edge of the neck 304. The venting process will be described in further detail below when discussing the nipple venting membrane of the nipple assembly 104.
(19) According to one embodiment, the container 102 includes a coupling channel 320 proximate to the container bottom 306. The coupling channel 320 may be created during the molding process and may be configured as a continuous channel around the circumference of the container 102. Alternatively, the coupling channel 320 may be configured as two or more depressions positioned on opposing sides of the container 102. The coupling channel 320 provides a means for attaching the detachable bottom 108 or any other accessory.
(20) Turning briefly to
(21) The container 102 may be manufactured from clear rigid Grilamid Nylon or other suitable material. The container 102 may be sized to accommodate any volume of fluid. According to two illustrative examples, the container 102 may be manufactured in two sizes corresponding to a larger 240 ml volume and a smaller 120 ml volume. The nipple assembly 104, cover 106, and detachable bottom 108 are universal in that they are interchangeable between all containers 102 of all volumes.
(22) Turning to
(23) In contrast, the embodiments described herein provide a one-piece nipple assembly that simplifies coupling and decoupling the nipple assembly 104 to and from the container 102, as well as simplifying cleaning. The ring substrate 406 may be manufactured from any material having a rigid or semi-rigid characteristic that is suitable for use within a food container. An example includes, but is not limited to, a talc, glass, or mineral fiber reinforced plastic. The ring substrate 406 includes nipple assembly threads 424 configured for coupling to the neck threads 310 on the container 102. The ring substrate 406 may additionally include a flow rate indicator 410 that notifies the user as to the fluid flow rate associated with the particular nipple assembly 104. Alternatively, the flow rate indicator 410 may be incorporated into the dome overmold 402 discussed below. The ring substrate 406 includes a cover locking undercut 422, which is a recessed portion of the ring substrate proximate to the container 102 when the nipple assembly 104 is coupled to the container 102. This cover locking undercut 422 is configured to engage a corresponding feature of the cover 106 to couple and decouple the cover 106 onto the nipple assembly 104 as described below with respect to
(24) The ring substrate 406 is encompassed by a dome overmold 402 with nipple head 404. The dome overmold 402 may be manufactured from silicone, thermoplastic rubber, thermoplastic elastomer, or other suitable material having a pliable characteristic. The dome overmold 402 with the nipple head 404 is created around the ring substrate 406 so that the two materials are bonded together, creating a one-piece nipple assembly 104. The dome overmold 402 and nipple head 404 may include multiple textures 408A-408C (collectively referred to as texture(s) 408). In the example shown in
(25) As an example, the nipple head 404 may include a texture 408C having a roughness average (RA) of approximately 2.0 micrometers, the base of the dome overmold 402 may include a texture 408A having a RA of approximately 5.0 micrometers, and the main body portion of the dome overmold 402 may include a texture 408B that is approximately between 2.0-5.0 micrometers. The textures 408A-408C may transition between one another smoothly, offering a seamless texture gradient throughout the surface of the nipple assembly 104. The textures 408 provide the nipple assembly 104 with a uniquely realistic look and feel of skin in order to better simulate the human breast and provide tactile feedback to the infant to promote infant latching and feeding.
(26) Another feature of the nipple assembly 104 that enhances the realism associated with the look and feel of the nipple head 404 and dome overmold 402 is the variable wall thickness of the silicone or other material of the nipple assembly 104. As seen in the cross-sectional view of the nipple assembly 104 shown in
(27) As seen in
(28) Returning to the cross-sectional and top views of
(29) According to various embodiments, the nipple assembly 104 includes an internal flow assist mechanism 416 that is molded or otherwise incorporated into an inside surface of the nipple head 404 and dome overmold 402. The internal flow assist mechanism 416 provides multiple benefits. First, the internal flow assist mechanism 416 assists the flow of fluid through the nipple head 404, even when the infant is biting or pulling on the nipple head 404. With a conventional nipple head, when the infant bites or pulls, opposing sides of the nipple head 404 are pressed together, which closes off the passage between the container 102 and the drinking pinhole 412 and prevents the infant from feeding.
(30) However, utilizing the nipple assembly 104 of the various embodiments described herein, the internal flow assist mechanism 416 provides fluid passageways through the nipple head 404 when the opposing walls of the nipple head 404 are compressed to abut one another when biting or pulling. According to one embodiment, the internal flow assist mechanism 416 may be created by molding the nipple assembly 104 with channels or indentations within the inside surface of the nipple head 404 and dome overmold 402 according to the desired pattern. According to an alternative embodiment, the internal flow assist mechanism 416 may be created by molding the nipple assembly 104 with additional material (i.e., ribs or projections) projecting outward from the inside surface of the nipple head 404 and dome overmold 402 according to the desired pattern.
(31) Another benefit of the internal flow assist mechanism 416 is to provide strength and/or resiliency in the nipple head 404. Depending on the pattern of the internal flow assist mechanism 416, the particular pattern may strengthen the nipple head 404, particularly when the internal flow assist mechanism 416 is manufactured by molding the nipple assembly 104 with additional material projecting outward from the inside surface of the nipple head 404 and dome overmold 402 according to the desired pattern. Additionally, the pattern of the internal flow assist mechanism 416 may provide a resiliency that assists in returning a pulled nipple head 404 to an original position. For example, a vortex pattern 416A as shown in

(35) The cover 106 has a cover coupling ridge 506 that projects from an interior surface of the cover 106 and is positioned to engage the cover locking undercut 422 of the ring substrate 406. The cover coupling ridge 506 may be created during the molding process and may be configured as a continuous ridge around the circumference of the interior surface of the cover 106. Alternatively, the cover coupling ridge 506 may be configured as two or more projections positioned on opposing sides of the interior surface of the cover 106, as shown in
(36) The cover 106 additionally may include a cover removal widening 508 that allows for the cover 106 to be easily snapped off using a thumb or finger of one hand. The cover removal widening 508 is a flaring of the cover material in one location. This flaring at one location which projects the cover 106 away from the feeding bottle 100 enough to allow the cover 106 to be easily pushed upward and off of the nipple assembly 104 from below at that location. The cover removal widening 508 is more easily seen in

(39) The routine 700 begins at operation 702, where the ring substrate 406 is created. As discussed above, the ring substrate 406 may be manufactured from a talc, glass, or mineral fiber reinforced plastic or any other suitable rigid or semi-rigid material. The ring substrate 406 may be created in the desired shape and size using injection molding or other known molding techniques. According to various embodiments, the ring substrate 406 may include the nipple assembly threads 424, a flow rate indicator 410, the cover locking undercut 422, and any number of one dimensional locking part removal mechanisms 428 used to remove the ring substrate 406 from the tool after manufacturing.
(40) From operation 702, the routine 700 continues to operation 704, where the nipple head 404 and dome overmold 402 are formed around the ring substrate 406 to create a one-piece nipple assembly 104. The nipple head 404 and dome overmold 402 may be manufactured from silicone or other suitable pliable material. The material for the nipple head 404 and dome overmold 402 may be injection molded into a mold that includes the ring substrate 406 so that, when cured, the dome overmold 402 bonds to the ring substrate 406. The mold used for the nipple assembly 104 may include the desired textures 408 and produce the variable wall thicknesses described above. The mold may additionally be formed to create the nipple venting membrane 426.
(41) The routine 700 continues from operation 704 to operation 706, where the container 102 is created using injection stretch blow molding or other known techniques. The container 102 may include tapering walls, a neck 304 having the desired offset angle 308, the neck threads 310, a non-slip broadening 305, and the coupling channel 320. From operation 706, the routine 700 continues to operation 708, where the detachable bottom 108 is created. The detachable bottom 108 may be manufactured from thermoplastic elastomer, silicone, or other suitable non-slip material in any desired color. The material of the detachable bottom 108 may be molded to include the coupling ridge 602 to allow the detachable bottom 108 to be snapped on and off of the container bottom 306.
(42) At operation 710, the cover 106 is created using a polypropylene, thermoplastic elastomer or other suitable rigid material and known molding techniques. The cover 106 may include an outer surface 502 that substantially follows the contour of the nipple assembly 104, a nipple compressing surface 504 on the inside of the cover 106, a cover coupling ridge 506 that projects from an interior surface of the cover 106, and a cover removal widening 508 as described above. At operation 712, the nipple assembly 104 may be threaded onto the container 102 and the detachable bottom 108 and the cover 106 snapped into place to produce the assembled feeding bottle 100, and the routine 700 ends.
