Abstract

A feeding-bottle has a teat (1) that is clamped to the bottle-neck (6) under an annular lip (7) of a collar (5) screwed to the bottle (4). The lip (7) engages in a circumferential groove (11) in the teat-bell (10) for pressing the retention flange (2) of the teat (1) onto the rim (3) of the neck (6) in airtight seal. Air is admitted to the bottle (4) via a flow-limiting slit (18) at the end of a passage (14) of lozenge cross-section that extends radially through the flange (2) beneath a lug (19). The lip (7) bears on the lug (19) to compress the flange (2) so that adjustment of the tightness of the collar (5) varies constriction of the passage (14) for regulating the air-flow into the bottle (4).

Description

Feeding-Bottles
This invention relates to feeding-bottles, and to teats for use therein.
According to one aspect of the invention there is provided a feeding-bottle having a teat, wherein a path for air to enter the bottle extends through a portion of the teat spaced from its nipple, and means is provided for selective compression of said portion in regulation of air-flow via said path.
Said means of the feeding-bottle may involve a member for retaining the teat attached to the bottle, and in this respect the retaining member may be adjustable to bear on said portion of the teat to a selectively-variable extent for regulation of the air-flow. The retaining member may be a collar that is screwed onto a neck of the bottle over an annular flange of the teat for retaining the teat attached to the bottle, compression of said portion being increased by turning the collar to tighten it on the bottle. The collar may have an inturned annular lip that bears on a lug which is upstanding from the flange of the teat, and in these circumstances the air-path may comprise a radial passage within the flange beneath the lug so that the air-path is constricted by tightening of the collar on the bottle.
According to another aspect of the invention there is provided a teat for a feeding-bottle, wherein a path for air to enter the bottle extends through an annular retention flange of the teat such that compression of the flange constricts the air-path. The path may comprise a radial passage within the flange so that compression of the flange constricts air-flow through the passage. The passage, which may have a cross-section of lozenge configuration, may extend within the flange beneath a lug that is .upstanding from the flange such that force exerted on the lug to compress the flange constricts the air-path.
A slit inside the teat may be included in the air-path to act by resilience of the teat to limit air-flow via the path. The slit may be in a projection from the inner rim of the flange.
A feeding-bottle having a teat in accordance with the present invention, will now be described, by way of example, with reference to the accompanying drawings, in which:
Figures 1 and 2 are, respectively, a side elevation and a plan of the feeding-bottle of the invention;
Figure 3 is a sectional elevation of the feeding-bottle taken on the line III-III of Figure 2;
Figure 4 is a sectional elevation of the feeding-bottle taken on the line IV-IV of Figure 1;
Figure 5 shows detail of the feeding-bottle to enlarged scale, the detail being of the area V of Figure 4;
Figures 6 and 7 are perspective views of the teat according to the present invention, used in the feeding- bottle of Figures 1 to 4 ;
Figure 8 is a side elevation of the teat of Figures 6 and 7 ; and Figure 9 shows detail of the teat to enlarged scale, the detail being of the area IX of Figure 8.
The feeding-bottle to be described has an angled teat for helping to reduce the tendency to colic in young babies (for example, up to six months old) when fed from a straight teat. However, the invention and its application are not dependent on the use of an angled teat and the angled teat of the feeding-bottle to be described may in this respect be replaced by a straight teat for young as well as older babies.
Referring to Figures 1 to 5, the angled teat 1, which is of silicone rubber, has a peripheral, annular flange 2 that is seated on the open-end rim 3 of a wide-necked bottle 4. A cylindrical collar 5 is screwed onto the neck 6 of the bottle 4 over the flange 2 , and has an in- turned annular lip 7 which engages a shoulder 8 of the teat 1. More particularly, and as shown more clearly in Figure 5, the underside of the flange 2 has a peripheral groove 9 that seats on the rim 3, and the bell 10 of the teat 1 has a circumferential groove 11 just above the flange 2 that is engaged by the lip 7. The lip 7 engages in the groove 11 when the bell 10 surmounted by the nipple 12, is pushed through the collar 5 in assembly of the feeding-bottle. Screwing down of the collar 5 onto the neck 6 of the bottle 4 pulls the lip 7 down onto the shoulder 8 within the groove 11. This presses the flange 2 hard down onto the rim 3, creating a liquid and airtight seal with it within the groove 9.
When the feeding-bottle is in use, the bottle 4 containing milk (expressed or formula) is tipped up through some sixty degrees so as to fill the teat 1 fully; because of the angled form of the teat 1 in this case, its nipple 12 is, however, presented to the baby less steeply. Air is admitted to the bottle 4 to enable the baby to draw the milk gently (without gulping) through small holes 13 in the nipple 12 as he/she sucks on the teat 1. The air is admitted via a passage 14 (see Figure 5 especially) in the annular flange 2, and the rate with which it can enter, and therefore the rate of milk-flow to the baby, is adjustable simply by turning the collar 5 slightly in the sense to tighten or loosen it on the bottle 4.
Referring now also to Figures 6 to 9 , the passage 14 has a cross-section of elongate-lozenge configuration (most clearly seen in Figure 9) , and extends radially inwards through the flange 2 from its outer rim 15 to terminate within a small projection 16 (see Figure 7) on the inner rim 17 of the flange 2. A fine slit 18 (see Figures 5 and 7) , which extends into the projection 16 at right angles to the passage 14, allows air entering the passage 14 from around and under the collar 5, to pass into the bottle 4. The slit 18, because of the resilience of the silicone rubber, acts as an air-flow limiter, but regulation of the flow within this established limit is achieved as indicated above, by turning the collar 5.
In the latter respect, the underside of the lip 7 of the collar 5 abuts a lug 19 that is upstanding from the flange 2 above the passage 14 (see Figures 5, 6 and 9) . Thus, turning the collar 5 to tighten it on the bottle 4 exerts pressure via the lug 19 to compress the flange 2 in the region of the passage 14. The resulting constriction of the passage 14 reduces the possible level of air-flow into the bottle 4, and therefore the flow of milk from the teat 1; in the extreme case where the passage 14 is squeezed closed, the flow may be effectively stopped. Flow can be increased from the reduced level, simply by turning the collar 5 to loosen it slightly on the bottle 4. This allows the flange 2, because of the resilience of the silicone rubber, to recover from the compression and, depending upon the extent of loosening, return the passage 4 to its full cross-section .
The teat 1 used in conjunction with the bottle 4 and collar 5 as described above has the distinct advantage of enabling air to be readily admitted to the bottle 4, but nonetheless in a limited and selectively-regulatable manner. The structure of the teat 1 is such that this advantage is achieved simply, without the use of a special bottle.
