Summary for Patent: 6,089,389

Title:	Two-compartment container and method of preparing the same
Abstract:	A container holding two separate components, which are mixed prior to use is provided. The container comprises a housing defining a first compartment having a sealable opening and a neck portion between said first compartment and said opening. The container further comprises a displaceable member which is disposed within the housing which has a partition wall with an edge adapted for sealing engagement with the internal wall of the neck portion, thereby defining a second compartment sealed from the first compartment and being in flow communication with the opening. The displaceable member is axially displaceable between two positions along an axis extending through the neck portion. These two positions comprise a first position where the edge of the partition wall sealably engages the internal walls of the neck portion, and a second position where the edge of the partition wall and the internal walls of the neck portion are disengaged, permitting flow communication between the two compartments. The container with two components is prepared by first introducing a first component into the first compartment, placing the displacable member within the compartment and fitting it into said first position, introducing the second component into the second compartment and sealing the opening.

Application Number:	08/811,007
Patent Claims:	1. A baby's feeding bottle comprising: a housing for separately storing at least two different components, the housing having a bottom wall, a dispensing opening opposite the bottom wall, at least one side wall of unitary structure and a neck portion positioned between the bottom wall and the dispensing opening, the neck portion defining a first bottom compartment between the bottom wall and the neck portion and a second top compartment between the neck portion and the dispensing opening; a displaceable member disposed in the housing in a manner permitting flow-communication between the second compartment and the dispensing opening, the displaceable member having a recess at its top for receiving a flange of a nipple and further having a partition wall adapted for sealing engagement with the neck portion so as to seal the two compartments one from the other, the partition wall being dependent from a manipulable portion of the displaceable member by at least one stem, the displaceable member and housing adapted so that the interior of the displaceable member is in flow-communication with the interior of the compartment within which it is disposed at all times; wherein the partition wall is axially displaceable between a first low position where the partition wall sealingly engages the neck portion, and a second upper position where the partition wall and the neck portion are disengaged permitting flow-communication between the two compartments. 2. A feeding bottle according to claim 1, wherein the partition wall depends from the manipulable portion by a plurality of stems. 3. A feeding bottle according to claim 1, wherein the partition wall depends from the manipulable portion by at least one stem connected to the periphery of the partition wall. 4. A feeding bottle according to claim 1, wherein the displaceable member and the opening have cooperating threads and the displaceable member is screw-engaged with the opening of the container, the axial displacement being achieved by rotation of the displaceable member with respect to the housing. 5. A feeding bottle according to claim 1, wherein an outer face of the manipulable portion has an axial groove engaging a projection of a cap such that rotation of the cap yields rotation of the displaceable member. 6. A feeding bottle according to claim 1, wherein the nipple is retained in a receptacle formed in the displaceable member by means of a nipple-retaining ring snap-fitted into the receptacle. 7. A feeding bottle according to claim 1, wherein the neck portion is of unitary structure such that it cannot be disconnected into multiple pieces. 8. A feeding bottle according to claim 7, wherein the housing is fabricated out of raw material as one continuous piece such that it is not assembled from two or more pieces. 9. A feeding bottle according to claim 8, wherein the neck portion is formed as a constricted portion in an otherwise substantially cylindrical housing. 10. A feeding bottle according to claim 8, wherein the displaceable member and the dispensing opening have cooperating threads and the displaceable member is screw-engaged with the opening of the container, the axial displacement being achieved by rotation of the manipulable portion with respect to the housing. 11. A bottle according to claim 10, wherein the manipulable portion is an annular ring which forms the opening of the displaceable member, the annular ring cooperating with and surrounding the dispensing opening. 12. A process for preparing a baby's feeding bottle for separately holding two components of a formulation to be mixed with one another within the bottle prior to use, the process comprising: (a) providing a housing for storing at least two different components, the housing having a bottom wall, a dispensing opening opposite the bottom wall, at least one side wall of unitary structure and a neck portion positioned between the bottom wall and the dispensing opening, the neck portion defining a first bottom compartment between the bottom wall and the neck portion and a second top compartment between the neck portion and the opening; (b) introducing the first component of the formulation into the housing; (c) providing a displaceable member in the housing in a manner permitting flow-communication between the second compartment and the dispensing opening, the displaceable member having a recess at its top for receiving a flange of a nipple, a partition wall adapted for sealing engagement with the neck portion so as to seal the two compartments one from the other, an opening for receiving at least one of the components, a manipulable portion for controlling axial movement of the displaceable member, the partition wall being dependent from a manipulable portion of the displaceable member by a plurality of stems, the displaceable member and housing adapted so that the interior of the displaceable member is in flow-communication with the interior of at least one compartment at all times and the displaceable member may be axially displaced along an axis extending through the neck portion between a first position where the partition wall engages the neck portion and a second position where the partition wall and the neck portion are disengaged providing flow-communication between the two compartments; (d) placing the displaceable member within the housing in the first position; (e) introducing the second component into the housing; and (f) placing the nipple into the recess. 13. A process according to claim 12, further comprising the following additional step: (g) snap-fitting a nipple-retaining ring into the recess. 14. A process according to claim 13, comprising providing the housing fabricated out of raw material as one continuous piece such that it is not assembled from two or more pieces . 15. A process according to claim 12, further providing sterile water as the first component and a powdered formulation as the second component. 16. A process according to claim 12, comprising providing the housing having the neck portion of unitary structure such that it cannot be disconnected into multiple pieces.
