ABSTRACT:
This invention relates to liquid feed bottles for use by infants and possibly also for use by young animals. The invention also relates to methods of making such bottles.
FIG. 1
of the accompanying drawing shows, in exploded view, a conventional liquid feed bottle of the kind commonly used to feed milk to infants in hospitals. The bottle comprises two sub-assemblies: the first comprises a glass container
1
bearing a label
2
for identifying matter and having a screw neck
3
closed by a metal lid
4
. The closed container contains liquid milk feed in a sterile condition; the second sub-assembly comprises a hollow vacuum-formed cap
5
having a projecting ledge
6
to which is sealed a sealing foil
7
. A plastics ring
8
and a rubber teat
9
are accommodated in the sterile space enclosed by the cap
5
and the foil
7
. These two sub-assemblies are supplied to the user, such as a nurse in a hospital, who removes the foil
7
from the ledge
6
to expose the ring
8
and teat
9
. The two latter components are attached to the container
1
in place of the metal lid
4
, to provide a liquid feed bottle ready for use. Such a known bottle thus comprises six components (apart from the milk), and the invention aims to provide a liquid feed bottle which has fewer components and is simpler and cheaper to manufacture.
According to one aspect of the invention there is provided a liquid feed bottle holding a liquid feed for internal consumption by a young mammal, the bottle comprising a body which holds the liquid feed and which has a container portion and a teat or spout with an outlet orifice, and a cap which covers and protects the teat or spout, wherein the cap is bonded or sealed to the body, at least a portion of the cap being initially detachable from the body by rupturing a tear strip and being subsequently securable on the body by a press fit.
According to another aspect of the invention there is provided a method of making a bottle containing a liquid feed, comprising attaching a teat or spout and a cap to a container portion pre-filled with the liquid feed to yield a filled and sealed bottle with the teat or spout covered and protected by the cap at least a portion of which, on rupturing a tear strip, is detachable from the teat or spout to expose an outlet orifice in the teat or spout.
According to a yet further aspect of the invention there is provided a method of making a bottle containing a liquid feed, comprising attaching together a teat or spout and a cap to form a sub-assembly, and attaching the sub-assembly to a container portion pre-filled with the liquid feed to yield a filled and sealed bottle with the teat or spout covered and protected by the cap at least a portion of which, on rupturing a tear strip, is detachable from the teat or spout to expose an outlet orifice in the teat or spout.
The invention also relates to a method of making a bottle containing a liquid feed, comprising blow moulding a pre-form to form a bottle blank having a body with a teat or spout, filling the blank with the liquid feed whilst the bottle is oriented with its teat or spout lowermost, sealing a filling hole to form an enclosed bottle containing the liquid feed, inverting the filled bottle so that the teat or spout is uppermost, forming an outlet orifice in the teat or spout to enable the liquid feed to be extracted from the bottle, and attaching to the body a cap which covers and protects the teat or spout and at least a portion of which, on rupturing a tear strip, is detachable from the body.
