[0001] The invention relates to an adaptor for connecting a feeding container to an enteral
feeding coupling, in particular for a baby bottle feeding assembly.
[0002] The adaptor of the present invention in particular is used in the field of medical
supplies and nursing care. For example in some hospitals patients are fed through
a feeding container connected to a feeding set or feeding assembly which is connected
to the patient via a feeding conduit in order to feed the patient with a liquid contained
in the feeding container. In such a case a baby bottle can be used for the feeding
container. However, the feeding container or baby bottle can be purchased from many
different manufacturers and, thus, there is a broad range of different sizes and diameters
of the feeding containers and their openings.
[0003] It is an object of the present invention to provide an adaptor for connecting a feeding
container to an enteral feeding coupling for an easy and fluid-tight connection and
which can be used for different sizes of feeding containers.
[0004] The above object is achieved by an adaptor according to claim 1. The adaptor comprises
a supporting member for connection with the feeding container, a sealing which is
fastened to the supporting member suitable for providing fluid-tight connection between
the adaptor and the feeding container and an end section suitable for connecting the
adaptor to the feeding coupling.
[0005] Preferably, the adapter is configured to cooperate with a range of different sizes
of feeding containers and/or with a range of different diameters for the opening of
the feeding containers. In particular, the sealing is shaped and/or fixed to the adaptor
in such a manner that the adaptor can cooperate with different sizes of the opening
of the feeding container. Preferably, the sealing is fastened to the supporting member
in an area of the supporting member suitable for providing a fluid-tight connection
between the adaptor and the feeding container and/or suitable for use for different
sizes of the opening of the feeding container.
[0006] Preferred embodiments are described in claims 2 to 15.
[0007] According to a preferred embodiment, the sealing comprises at least one sealing member.
In particular, the sealing member can be formed as a ring, annular or plate-like etc.
Preferably, the at least one sealing member can be connected to the lower side, the
upper side and/or the face side of the supporting member. The connection can be made
by means of moulding the sealing material onto or over the supporting member, preferably
the supporting plate.
[0008] The sealing member can also be designated as sealing portion, sealing unit or gasket.
If in the following the sealing itself, the sealing member or features thereof are
mentioned, then only one sealing member, the sole sealing member, several sealing
members or all sealing members can have the features and/or characteristics mentioned.
[0009] According to a further preferred embodiment, the sealing member is integrally formed
with the supporting member. In particular, the sealing member is moulded at least
partially over or to the supporting member. In other words, preferably, sealing member
and supporting member build a one-piece structure which is produced by moulding a
sealing material on or over the preformed supporting member made of a rigid material
in order to secure the sealing member to the supporting member. For example, the supporting
member is made of a rigid plastic material and the sealing member is made of a resilient
material. Further, it is preferred to provide the adaptor with the supporting member,
the sealing member and the end section as a one-part member or element. Preferably,
at least the supporting member is produced by means of injection moulding. The supporting
member can be a base or plate, in particular in form of an annular ring.
[0010] In an advantageous embodiment, the sealing member extends substantially parallel
to the supporting member or in an inclined direction from the supporting member. In
particular, the sealing member extends in a direction from the supporting member to
include an angle of more than 90°, for example in the range of 91° to 135°. Particularly
via the inclined extension of the sealing member and/or via positioning the sealing
member in a predetermined area of the supporting member, it is possible to use the
adapter for feeding containers having different opening diameters.
[0011] In a further preferred embodiment, the sealing member is tapered and/or is shaped
annular. To simplify the placement of the adapter on the opening side of the feeding
container, the free end of the sealing member is tapered.
[0012] According to a preferred embodiment, the adaptor comprises an intermediate section
between the supporting member and the end section. Like the supporting member and/or
the sealing member also the intermediate section can be formed annular or can be provided
with a base plate and a wall extending form the base plate. Furthermore, the intermediate
section can build a shoulder. In general, the intermediate section is formed to improve
the rigidity of the adapter.
[0013] In a preferred embodiment, a thin layer which can be pierced through when the feeding
coupling is connected to the adaptor. Preferably, the thin layer is connected to the
intermediate section and/or the supporting member. In particular, a film or foil,
especially made of plastic material is used for the thin layer.
[0014] According to a preferred embodiment, a fastening element is provided for detachably
or removably fastening the adaptor to the feeding container. Basically, the fastening
element can be integrally formed with the supporting member or can be separate from
the supporting member, in particular shaped as a cap. Preferably, the fastening element
comprises a threaded section for engaging a threaded section of the feeding container.
This enables a screw connection of the feeding container and the adaptor.
[0015] In order to provide a connection between the end section and the feeding coupling,
the end section can comprise a threaded section for engaging a threaded section of
the feeding coupling.
[0016] In a further preferred embodiment, the feeding coupling comprises a tube having a
feeding channel in order to allow a fluid connection between the feeding container
and the feeding conduit. Preferably, the tube has a first end extending in the area
of the feeding container and a second end extending up to the outer end of the feeding
coupling adjacent to the feeding conduit. The first end of the tube can have a tapered
and/or sharp shape in order to pierce through the thin layer when the feeding coupling
is connected to the adaptor. Before the feeding coupling is mounted to the adaptor
the thin layer of the adapter allows a fluid-tight seal of the feeding container closed
with the adaptor mounted at the opening.
[0017] According to a preferred embodiment, the feeding coupling comprises a first end portion
for fastening the feeding coupling to the end section of the adaptor and a second
end portion for connecting a feeding conduit to the feeding coupling. To provide a
screw connection between feeding coupling and adaptor the feeding coupling comprises
a threaded section for engaging the threaded section of the end section.
[0018] The present invention provides an adaptor for a quick and fluid-tight connection
between a feeding container, in particular a baby bottle, and a feeding coupling,
in particular a feeding set. Preferably, the sealing is made of a softer material
than the supporting member and the softer material is over moulded onto the harder
material of the supporting member. The sealing member can be tapered so as to allow
for a seal within different diameter of neck bottles. The thin layer allows for a
mixture to be mixed in the feeding container if required before the feeding coupling
is connected to the adaptor. In order to fasten the adaptor to the feeding container
in the area of the container opening a cap can be used as a fastening element.

[0020] Fig. 1 schematically shows a feeding coupling 80 connected to a feeding container
70 by means of an adaptor 10 according to the present invention. The feeding container
70 is a baby bottle having an opening 72 at the upper side 74. The feeding coupling
80 can be connected with a feeding conduit 90 (cf. Fig. 2) to feed a patient with
a fluid contained in the feeding container 70. In order to feed the patient, the feeding
container 70 is mounted such that it hangs downward.
[0021] As can be seen from Fig. 2 to 6 the adaptor 10 comprises a supporting member 20 for
connection with the feeding container 70, a sealing 30 which is fastened to the supporting
member 20 in an area of the supporting member 20 suitable for providing a fluid-tight
connection between the adaptor 10 and the feeding container 70 and an end section
50 suitable for connecting the adaptor 10 to the feeding coupling 80. Further, there
is an intermediate section 40 between the supporting member 20 and the end section
50. The intermediate section 40 is made of the same rigid plastic material as the
supporting member 20 and the end section 50. Further, a fastening element 60 shaped
as a cap and having a base plate 62 and a wall 64 for detachably fastening the adaptor
10 to the feeding container 70 can be taken from Fig. 1 and 2. The wall 64 is provided
with a threaded section 66 for engaging with a threaded section 79 on a outside 78
of the feeding container 70. Preferably, the supporting member 20, the sealing 30,
the intermediate section 40 and the end section 50 are shaped annular.
[0022] As Fig. 2 shows, the supporting member 20 comprises a supporting plate or ring 22
which is applied on a rim 76 at the upper side 74 of the feeding container 70 around
the opening 72.
[0023] Further, as can be taken from Fig. 2 to 6, the sealing 30 comprises an annular shaped
sealing member 31 having a first end 32 which is fixed to the supporting plate 22
and a second end 33 which is a free end extending into the interior of the feeding
container 70. The sealing member 31 is moulded at least partially over or moulded
to the supporting member 20 in an area of the supporting plate 22 suitable for providing
a fluid-tight connection between the adaptor 10 and the feeding container 70. According
to Figs. 2 to 4, the sealing member 31 extends substantially in a longitudinal direction
L of the adaptor 10. "Substantially" means in the present embodiment that the sealing
member 31 extends in an inclined direction including an angle α between the extension
of the sealing member 31 and the extension of the supporting plate 22. Preferably
this angle α is more than 90°, in particular between about 91° and about 135°. The
second end 33 is a tapered end.
[0024] In particular, the configuration of the inclined extension and/or the tapered end
33 of the sealing member 31 enables the adaptor 10 to cooperate with a range of different
diameters for the opening 72 and/or with a range of different sizes of feeding containers
70. Moreover, the sealing member 31 is shaped and/or fixed to the adaptor 10 in such
a manner that the adaptor 10 can cooperate with different sizes of the opening 72
of the feeding container 70.
[0025] The intermediate section 40 comprises a base 42, in particular shaped as an annular
plate, and a wall 43 formed integrally with the base 42 and made of the same material.
The wall 43 extends substantially parallel to the longitudinal direction L and the
base 42 extends in the radial direction R parallel to the supporting plate 22. This
shape improves the stability of the whole adaptor 10.
[0026] Further, a thin layer 44, in particular a film or foil, is mounted to the adaptor
10 in the area of the intermediate section 40. Preferably, the thin layer 44 is bonded
to the base 42. This thin layer 44 seals the feeding container 70 when the adaptor
10 is mounted to the feeding container 70 and is secured by means of the fastening
element 60.
[0027] The end section 50 is shaped cylindrical and comprises a first end 52, a second end
54 and a central bore 56. Also the end section 50 is formed integrally with the supporting
member 20 and the intermediate section 40 and from a rigid plastic material. The second
end 54 is formed as a free end. The wall of the end section 50 comprises a threaded
section 58 in order to connect the feeding coupling 80 to the end section 50 and,
thus, to the adaptor 10.
[0028] The feeding coupling 80 comprises a first end portion 86, a second end portion 88
and a threaded section 89. A tube 82 extends along the longitudinal direction L through
first end portion 86 and/or second end portion 88 to provide a feeding channel 83
from the interior of the feeding container 70 to an outlet end of the tube 82 and
to the feeding conduit 90 connected to the second end portion 88. In order to achieve
the flow of the feeding fluid out from the feeding container 70 to the feeding conduit
90, the tube 82 has a length which is long enough that a first end 84 of the tube
82 extends through the thin layer 44 into the interior of the feeding container 70.
A second end 85 of the tube 82 ends at the upper side of the second end portion 88.
In order to connect the feeding coupling 80 to the end section 50 the first end portion
86 comprises a threaded section 89 to be engaged with the threaded section 58.
[0029] To connect the feeding coupling 80 with the adaptor 10 the first end 84 of the tube
82 is introduced into the bore 56. Then, the first end portion 86 is screwed with
its threaded section 89 on the threaded section 58 of the end section 50. While screwing
the feeding coupling 80 onto the end section 50 the sharp first end 84 of the tube
82 pierces through the thin layer 44 and enters into the upper area of the feeding
container 70. Finally, the feeding conduit 90 can be connected to the free second
end portion 88.
[0030] Fig. 7 shows the adaptor 10 according to a second embodiment, wherein only the sealing
30 is different compared to the first embodiment of Fig. 2. The sealing 30 comprises
the sealing member 31 corresponding to Fig. 2 and in addition a sealing member 34,
which can also be designated as gasket. The sealing member 34 is connected to a lower
side 24 of the supporting plate 22 and/or to the sealing member 31. Further, the sealing
member 34 extends parallel to the supporting plate 22. Preferably, the sealing member
34 is moulded onto the lower side 24.
[0031] Fig. 8 shows the adaptor 10 according to a third embodiment, wherein only the sealing
30 is different compared to the first embodiment of Fig. 2. The sealing 30 comprises
only the sealing member 34. The sealing member 34 is connected to the lower side 24
of the supporting plate 22 and extends parallel to the supporting plate 22. Preferably,
the sealing member 34 is moulded onto the lower side 24.
[0032] Fig. 9 shows the adaptor 10 according to a fourth embodiment, wherein only the sealing
30 is different compared to the first embodiment of Fig. 2. The sealing 30 comprises
only the sealing member 34. The sealing member 34 is connected to the lower side 24,
