Feeding bottle with tubular housing for clamping flexible container

Claim 2

A feeding bottle housing of tubular configuration with an open upper end adapted to receive a teat and which is adapted to accommodate an open-ended flexible container in the interior of the housing with a mouth zone of the container folded over the upper end of the housing, the housing comprising two longitudinally divided sections which are linked together along a longitudinally extending hinge zone and are movable about the hinge zone between open and closed positions and clamping means located on a lower portion of the housing to anchor the base of a flexible container and fix the extent of the mouth zone of the container available for folding over the upper end of the housing, the clamping means comprising cooperating and elongated tongue and groove formations integral with the two housing sections, the formations presenting clamping surfaces of complementary curved cross-sectional configuration which are movable relative to each other in a direction transverse to the formations and about the longitudinally extending hinge zone between a separated, inoperative position when the two housing sections are in an open position and an operative position in which they mate to engage between them a base portion of the container when the two housing sections are in a closed position, the tongue formation also defining at least part of a socket adapted releasably to receive a projecting spigot formation on a removable teat cap.

Claim 3

A feeding bottle housing as claimed in claim 1, wherein in the clamping surfaces of the formations are screw threaded, the threads being movable into and out of complementary mating relationship in a direction transverse to the formations.

Claim 4

A feed bottle housing as claimed in claim 1, wherein the mating surfaces include gripping formations.

Claim 5

A feeding bottle housing of tubular configuration with an open upper end adapted to receive a teat and which is adapted to accommodate an open-ended flexible container in the interior of the housing with a mouth zone of the container folded over the upper end of the housing, the housing comprising two longitudinally divided sections which are linked together along a longitudinally extending hinge zone and are movable about the hinge zone between open and closed positions, each section having a transverse floor section forming a floor in the lower portion of the interior of the housing when the longitudinal sections are in closed position and longitudinally disposed first and second clamp formations located on the floor sections of the two housing sections, the first clamp formation being in the form of a half tube having an internal peripheral region presenting a concave clamp surface and the second clamp formation being in the form of a tube having an external peripheral region defining a convex clamp surface complementary with the concave clamp surface and having a hollow interior bore defining a socket adapted releasably to receive a spigot formation on a removable teat cap, the convex and concave clamp surfaces being movable relative to each other about the longitudinally extending hinge zone between a separated inoperative condition when the two housing sections are in open position and a mating operative condition in which they are adapted to engage between them and anchor a base region of the container when the two housing sections are in their closed position.

Claim 6

A feeding bottle housing of tubular configuration with an open upper end adapted to receive a teat and which is adapted to accommodate an open-ended flexible container in the interior of the housing with a mouth zone of the container folded over the upper end of the housing, the housing comprising two longitudinally divided sections which are linked together along a longitudinally extending hinge zone and are movable about the hinge zone between open and closed positions, each section having a transverse floor section forming a floor in the lower portion of the interior of the housing when the longitudinal sections are in closed position and longitudinally disposed first and second clamp formations located on the floor sections of the two housing sections, the first clamp formation being in the form of a half tube having an internal peripheral region presenting a concave clamp surface and the second clamp formation being in the form of a tube having an external peripheral region defining a convex clamp surface complementary with the concave clamp surface and having a hollow interior bore defining a socket adapted releasably to receive a spigot formation on a removable teat cap, the convex and concave clamp surfaces being movable relative to each other about the longitudinally extending hinge zone between a separated inoperative condition when the two housing sections are in open position and a mating operative condition in which they are adapted to engage between them and anchor a base region of the container when the two housing sections are in their closed position.

Claim 7

A feeding bottle housing as claimed in claim 4, wherein first and second clamp formations present screw-threaded clamp surfaces of curved cross-sectional configuration, the threads being movable into and out of complementary mating relationship.

Claim 8

A feeding bottle housing as claimed in claim 4, wherein the mating surfaces include gripping formations.

Claim 9

A feeding bottle housing as claimed in any one of claims 1 to 6, containing a graduated contents scale along a wall of one of said housing sections and located between the upper end of said housing and the clamp formations to permit scaling of the contents of a container anchored in the housing.

Claim 10

A feeding bottle housing of tubular configuration with an open upper end adapted to receive a teat and which is adapted to accommodate an open-ended flexible container in the interior of the housing with a mouth zone of the container folded over the upper end of the housing, the housing comprising two longitudinally divided sections which are linked together along a longitudinally extending hinge zone and are movable about the hinge zone between open and closed positions and clamping means located on a lower portion of the housing to anchor the base of a flexible container and fix the extent of the mouth zone of the container available for folding over the upper end of the housing, the clamping means comprising cooperating tongue and groove formations located on the two housing sections, the tongue formation defining at least part of a socket adapted releasably to receive a projecting spigot formation on a removable teat cap, the clamp formations extending longitudinally relative to the housing and being movable relative to each other about the longitudinally extending hinge zone between an inoperative position when the two housing sections are in open position and an operative position, where they engage between them a base portion of the flexible container, when the two housing sections are in closed position.

Claim 11

A feeding bottle housing of tubular configuration with an open upper end adapted to receive a teat and which is adapted to accommodate an open-ended flexible container in the interior of the housing with a mouth zone of the container folded over the upper end of the housing, the housing comprising two longitudinally divided sections which are linked together along a longitudinally extending hinge zone and are movable about the hinge zone between open and closed positions and clamping means located on a lower portion of the housing to anchor the base of a flexible container and fix the extent of the mouth zone of the container available for folding over the upper end of the housing, the clamping means comprising cooperating tongue and groove formations located on the two housing sections, the tongue formation defining at least part of a socket adapted releasably to receive a projecting spigot formation on a removable teat cap, the clamp formations extending longitudinally relative to the housing and being movable relative to each other about the longitudinally extending hinge zone between an inoperative position when the two housing sections are in open position and an operative position, where they engage between them a base portion of the flexible container, when the two housing sections are in closed position.
