Description

CONTAINER THAT HAS TWO OR MORE COMPARED IMIENTS FIELD OF THE INVENTION The present invention relates to two compartment containers and in particular to a single container of two compartments for single use, each compartment containing a separate component, for example, a liquid component or solid, to be mixed with one another by the end user before using them. BACKGROUND OF THE INVENTION A variety of formulations for human use are stored in the form of a dry particulate material (powder) and mixed shortly before being used to form a true solution or dispersion. This is the case, for example, with several formulas, including breast milk substitute (infant formula), formulas for adult feeding such as dietary powders and a variety of drugs, for example, antibiotics. The shelf life of said liquid formulations is limited, and this dictates the need to prepare them shortly before being used. The limited shelf life of liquid formulations is the result of a loss of activity of an active ingredient in the formula, for example, the loss of activity due to accelerated oxidation and / or hydrolysis once the ingredient is mixed with an active ingredient. liquid, etc. In addition, in many cases, the mixed formulation may be more susceptible to contamination by microorganisms. In some applications, for example, the formula for newborn children and for various drugs, including antibiotics, it is important that the correct amount (weight and / or volume) of the dry particulate material is mixed with the correct amount (weight and / or volume) of the liquid when the resulting formula is prepared. Much or little of one of the required components alters the ratio and changes the resulting formulation which may require being within narrow tolerances to have the appropriate effect. For example, in the case of formulas for infants if there is not enough dry formula the mixed liquid formulation will be diluted in which case the infant or infant will not be adequately nourished, or if there is too much dry formula the mixed liquid formulation will be very concentrated which It can give way to digestive problems and vomiting. Furthermore, in some applications it may be necessary that the "filling, storage and mixing of the two compartments is carried out under hygienic and in some cases sterile conditions and that the two components are of appropriate sterility and quality. In the home or in hospitals it is typically carried out by providing clean and sterilized bottles and nozzles, measuring a quantity of particulate material (dry particulate) from a container and placing it in the previously cleaned and sterilized bottle to which an appropriate measured quantity of water (usually tap water), saline solution or milk is added.The nozzle is inserted and the two constituents are stirred to form the mixed liquid formula.A variety of drugs, for example, antibiotics are prepared in a similar manner by the pharmacist or by the end user In applications where a formula prepared by mixing two constituent is has a short shelf life or where the quantities, quality or sterility of the two constituents is an important consideration in the preparation of the formula, a single container which can store separately the two constituents until the mixed formula is stocked, allows that the two constituents are mixed in the container and allows the mixed formula to be stocked from the container would be useful. In some such applications it may also be desirable for the container to be pre-packaged and additionally desirable to be configured and adapted for only one use by the end user and even more desirable if the container is useless after use. Such storage and assortment containers offer convenience, security and potential savings for the end user. First, a container for storage and assortment of two pre-packaged compartments offers the convenience of having the two constituent parts of a mixed formulation supplied in correct quantities in a single, easy to use container which is always ready to be mixed. In this way, a traveler can take as many pre-packaged containers as he wishes and mix the formula for use at any time, without having to measure the two or more constituents, or worry about forgetting or obtaining one or more constituents of the formula during the trip. Said container pre-packed, filled and packed under appropriate conditions, separately storing the constituent elements of the formula in a ready-to-mix manner, and adaptable to mix and furnish the resulting formulation provides a complete system for the end user. Second, storage and assortment containers of two single-use compartments offer the security of being packaged in the manufacturing plant where the sterility of the environment and the quality and sterility of each of the constituents of the mixed formula can be controlled. In addition, the amount of each of the two separate components can be controlled through precise measurements if they are pre-packaged in a single-use container at manufacturing facilities. Containers are known to have separate compartments for storing two components, for example, one with a dry particulate substance and the other with a liquid, both of which are mixed together before being used. Said two compartment containers typically employ a breakable or movable separator between the two compartments. The separation is fractured or displaced, as the case may be, to allow mixing. A major problem with designs of two-compartment containers is the complexity of the assembly, filling and packaging processes. The complexity results from the need for the assembly of the internal separation, through the typically restricted access of the container opening. Therefore there is a need for two compartment containers which are easily manufactured and which simplify the assembly, filling and packing process while offering easy and reliable operation. SUMMARY OF THE INVENTION It is an object of the invention "to provide a novel container having two or more compartments for storing two or more components intended to be mixed together before being used, the first of said components being typically a liquid and the other a particulate solid, for example, powdered substance It is a further object to provide a storage container and assortment of two or more compartments which can be easily assembled and filled with two or more components.It is another additional object to provide a storage container of two or more compartments which can be assembled and filled in a sterile environment and the sterile condition is not compromised by the preparation and assortment of the mixed formula.It is another object to provide a container of two or more compartments for storing two or more components intended to be mixed before use and which supplies the final formulation to formed by the mixture of two or more components.

It is a further object to provide a container of two or more compartments which can be externally activated to allow the two separately stored components to be mixed in an easy and reliable manner by an inexperienced end user. It is still another object of the invention to provide a complete system by means of a container of two or more compartments which is filled with the correct amount of each individual component to achieve an optimum mixed formula.

It is another object in some cases to provide a container of two or more compartments for single use to store two or more components destined before being used and which supplies the final formulation formed by the mixture of two or more components and which afterwards not It can be used. In accordance with one embodiment of the present invention, there is provided a container comprising: A cover having an opening for dispensing, an end portion and neck between said opening and said bottom end; and A displacement member disposed within said cover having a partition wall adapted to form a fluid-tight seal in said neck portion thereby defining two compartments separated by at least a portion of said wall portion; Said displaceable member being axially displaceable between two positions along an axis through said neck portion, said two positions comprising a first position wherein a fluid-tight seal is formed in said neck portion, and a second position. wherein the partition wall is decoupled from the neck portion to allow fluid communication between the two compartments. Thus, the neck portion divides the compartment into two compartments, one remote from said opening defining a first compartment and another adjacent to said opening defining a second compartment, the two compartments being separated from each other by and sharing at least a portion of the compartment. said separation wall when it is in its first position. The neck portion may be formed as a restricted portion that has a smaller cutting section than the adjacent areas of the cover. According to another embodiment, the neck portion can be formed by a radial wall projecting inwardly in an annular manner. In one embodiment of the invention the cover is cylindrical, the neck portion has a circular cross section and the partition wall is circular. In some embodiments, the edge of said partition wall is adaptable and is configured to form a fluid-tight seal with said neck portion.

The displaceable member may comprise an integral closure member that seals the assortment opening, for example, a fracture seal, which once fractured allows the assortment of the mixed formulation of the container. The container may also be provided with a closure assembly fitted to said opening. The closure assembly may be additionally replaceable and may or may not cooperate with the displaceable member. According to one embodiment of the invention said closure assembly comprises a removable plug. In accordance with one embodiment of the invention, said movable member has a peripheral portion for movable engagement with an upper end of the cover and has an opening extending outwardly defining said assortment opening. According to another embodiment of the invention, said movable member is movably coupled to the bottom end of the cover. Typically, according to this embodiment, the movable member has a wall, defining the bottom wall of the container, which is provided with a sealable opening to allow filling of a component within a first compartment. This mode typically has an assortment _ opening, but not necessarily different from the sealable opening in the displaceable member. The assortment opening may be equipped with a closure assembly designed in a manner to allow a controlled release of the container formulation. The closure assembly according to this embodiment is designed in a manner dependent on the intended use. For example, in the case of a container for medicinal formulation, the closure assembly may for example be a perforable rubber stopper, adapted to insert a syringe for the extraction of the medicinal formulation; the "closure assembly can also be designed to supply a fixed amount each time for a plurality of occurrences; the closure assembly can also be" "designed in the form of a spoon-shaped assortment unit; For use as a bottle to feed an infant, the closure assembly can be a "nozzle of size and shape according to the intended application. The closure assembly may also be equipped with an additional cover, for example, metallic paper cover or a cap covering the nozzle, to ensure: closure and / or maintenance, sterility. In the case of a lid covering the nozzle, the lid may be adjusted so as to seal the nozzle opening to prevent spillage of the liquid component during storage prior to mixing the liquid formulation. The present invention further provides a closure and assortment system useful for a bottle for infant feeding. The closure and assortment system of the invention comprises a seat member, a nozzle and a coupling member, the seat member is connected to or integral with a bottle to be fitted in its opening, and having a central opening with a surface of annular nozzle holder in its upper part surrounding said opening; the nozzle having, an annular shoulder seated on the nozzle holder surface and having a nozzle; the coupling member being adapted for adjustment on the bottle with an element thereof seated on the annular shoulder so that it is pressed against the nozzle support surface. The nozzle assembly can be configured and adapted so that the container is capable of single use. For example, the adjustment member may be configured to retain the nozzle immobile, or if removable it may be configured so that that part or a replacement part can not be placed in the container. In one embodiment, the assortment opening is provided with a filter or screen, typically an integral screen, for filtering undissolved particles present in the formula. In another embodiment, the central opening of the closure system is surrounded by a sleeve projecting upwardly coupled to the internal bottom walls of the nozzle. According to another embodiment, the coupling to the walls of the container by the coupling member is by means of instantaneous fixing.

The container of the invention can be designed for various uses. According to one embodiment of the invention, said container serves as an infant bottle, in which case said first compartment contains a liquid, typically sterilized water, said second compartment contains a formula for infant powder. According to another embodiment of the invention, said container is designed for storage of two components of a medicinal formulation, for example, said first compartment contains a dry particulate drug to be mixed with the liquid before being used, for example, a formulation _ of antibiotics. Depending on the type of formulation, the two components may be liquid, or they may be one liquid and the other may be a dry formulation or both may be dry formulations. The relative size of the first compartment and the second compartment can be designed according to their intended use. The container can be made for a single use, the container being generally disposable after a single use. In addition, the container can be recyclable, this being, it can be returned to the manufacturer after being used to be refilled. In addition, the container can also be made in a manner to allow filling with the two components by the end user. The container can also be constructed of materials to resist heating of the container in order to heat the contents. It may be advantageous in some applications to provide a container which is only capable of a single use, in particular the pre-packaged container which is only capable of a single use, in order to prevent an end user from reusing the container. Said container can provide a manufacturer with control over the quality of the product delivered, preventing the end user from refilling and reusing the container. A pre-packaged container offers the advantage of control over the proportion, quality and sterility of the components used and the mixed formulation delivered. It is envisaged that a container for single use can be achieved by controlling the strength of the materials and construction of the container, avoiding the possibility of refilling, destroying the operability of the container or a combination of these. For example, the container can be designed with a thin plastic material, or with a closure system which can be removed or reclosed after being opened, or a seal that can not be reformed (resealed) after being broken.

DETAILED DESCRIPTION OF A SPECIFIC MODE The embodiments described below refer to containers of the present invention, typically bottles for feeding-infant, having two compartments, one containing a formula in powder and the other containing a fluid, for example, water . The following description is provided to illustrate various specific configurations and example and the invention should not be considered as limited to these modalities. The features of the invention can also be used for different uses, for example, containers of two or more compartments for medicinal formulations, dietary powders to be reconstituted with a liquid ^, alcoholic beverages to form cocktails with other ingredients, wherein one compartment contains one component and the other compartment contains another different component to be mixed to form a formulation. The container of the present invention is generally described as storage of a dry powder component and a liquid component, the two components can be both liquids, both fluids, one can be a liquid (or fluid) and the other can be a dry formulation or both can be dry formulas. In the description of the invention the substances stored in the container have been described using the terms interchangeably,? "constituent", "material", "substance" and the like components: A infant feeding bottle 10 according to one embodiment of the invention, shown in Figures 1-3. The infant feeding bottle 10 has a cover 12 generally cylindrical with an opening 14 and a restricted neck portion 16. The neck portion 16 partially defines and divides the cover 12 into what will be a first compartment 18 below said neck portion and a second compartment 38 (see Figure 3). ) above the neck portion The container contains a movable member designated generally 20 which has a partition wall 22 with a border * 24 (see Figure 3) adapted to seal tightly with the inner walls of the neck portion 16. The fluid-tight coupling in this specific embodiment is secured by means of a peripheral seal ring 28 fitted in an annular groove 29 provided in the edge 24, although other means such as the geometry and shape of the edge 24 and the neck portion 16 as well as construction materials can also be used to provide the fluid tight seal. The partition wall 22 depends on and is connected to an annular portion 30_ by means of one or more projections 32 projecting downwards which form a connecting wall portion. In this embodiment, three spikes 32 projecting radially connect the partition wall 22 to the manipulatable portion 30. In the case of a single spike, it will typically be central, and in the case of a plurality of spikes, will typically be disposed in the periphery. In another example, the separating wall and the manipulable portion can be connected by the peripheral wall formed with openings. In a further example, the connection between the separation wall and the manipulable portion is by way of radial sections of the wall. The opening 14 is provided with an outer cord 34 at its periphery - for thread engagement with the inner cord - 36 on the displacement member 20. The manipulable portion 30 has a filling opening 31 through which the contents of the container it can be assortment, or materials added to the container. The wall portions 32, also referred to as spikes, are provided with or arranged with openings 35 communicating with the opening 31 so that a passage or conduit is formed through the displaceable member 20 so that the materials can pass between the interior and the exterior of the cover 12. In the specific example shown in Figures 1-3, when the movable member is fully threaded in the opening 14, the separation wall comes into fluid-tight contact with the internal walls of the portion. of neck 16, as can be seen particularly in Figure 3. In this position of the partition wall, referred to as "first state", the partition wall forms two compartments, a first compartment 18 below said partition wall and a second compartment 38 between said partition wall 22 and said opening 14. In the first state, at least a portion of the partition wall forms at least one separation of a common wall shared by both compartments. By rotating the displaceable member against the clock, the partition wall 22 is displaced axially towards the opening 14, decoupling the internal walls of the neck portion 16, thereby allowing communication between the two compartments, referred to as the " second state ". The infant feeding bottle 10 has a nozzle 42 which is fixed to the upper end of the displaceable member 20 by means of a nozzle retaining ring 44 which is press fit into a receptacle 46 at the upper end of the displaceable member 20. The infant feeding bottle shown further has a lid 48 which has a cylindrical portion 50 which densely engages the outer surface 52 of the displaceable member 20. The lid 48 can be configured to seal the opening 64 provided in the mouthpiece. 42 and protects the sterile condition of the mouthpiece. In addition, a seal made with aluminum foil, for example, may be provided on the opening 14 or the opening 31 to prevent the content or the mixed formula from leaving the container earlier than desired. The outer face 52 or the displaceable member 20 has an axial groove 54 which cooperates with a projection 56 projecting radially inwardly into the cover 48. By virtue of this engagement, when the cover 48 is rotated, it leads to the rotation of the displaceable member 20 and therefore its axial displacement. The bottle 10 can be constructed particularly for single use by means of a variety of forms such as, for example, using a thin plastic material for the cover, or the retaining ring of the nozzle 44 can be made so that it can not be made removed so that the nozzle is not removable and thus the container can not be refilled, or the nozzle retaining ring 44 and the upper end of the displaceable member 20 can be configured and adapted in such a way that the retaining ring 44 is removed or a replacement can not be fixed in the container so that the nozzle can not be repositioned in the container, or the displaceable member can be configured and adapted so that once it is moved from its seating position it can not reform a fluid-tight seal. It is envisaged that any or a combination thereof may be used in a single mode. In the specific embodiment shown in Figure 3, the first compartment 18 of the infant feeding bottle contains a liquid 60, for example, sterile water, and the second compartment 38 is filled with a powdered formula component 62. It is envisaged that the materials may be inverted and the first compartment 18 contain the powdered formula component and the second compartment 38 contain the liquid. The manner of producing the infant feeding bottle shown in Figures 1-3 is shown step by step in Figure 4. As can be seen, the manufacture is preferably effected under aseptic conditions using sterile components to ensure sterility of the bottle. In a first manufacturing step, as shown in Figure 4a, a first component, for example, a liquid 62, typically sterile water, is introduced into a cover 12. The first component is preferably inserted without the displaceable member placed in the cover, however the first component can be inserted with the movable member placed in the cover. For example, the first component can be -introduced with the movable member placed on the cover and in the second state so that the first "component" is allowed to pass into the first compartment, or the movable member can be in the first state and in forward moved axially to the second state before adding the second component so that the first component can pass into the first compartment.As a next step, shown in Figure 4B, the movable member 20 is screwed into the opening 14 of the cover where "the partition wall 22 comes into seal contact" with the interior walls of the neck portion 16. In the next step, shown in Figure 4C, a second component, for example, powder formula 62 is introduced into the second compartment 38 through the opening 31 and the opening 14 followed by sealing the opening with the nozzle 42 by means of the retaining ring 44 (Figure 4D) and then placing the cover 48 over said nozzle (Figure 4E). In this position the lid _48 seals the opening 64 in the nozzle 42. When the infant feeding bottle according to the invention is prepared in a manufacturing plant, the use of good quality water can be ensured. Good quality water can be defined by the concentration and composition of minerals, the absence of contamination such as heavy metals, bacteria, microorganisms and other hazardous materials and can be obtained by such processes or distillation. Also, and especially for newborns, exact amounts of powdered and liquid formula can be achieved by factory automation so that the correct proportion of the components is ensured, thereby providing an optimal mix that is not very diluted or very concentrated Figure 5 shows a way to prepare the infant feeding bottle for use. In a first step (Figure 5A), the displaceable member 20 is rotated so that the separation wall 22 is displaced axially whereby its edges are decoupled from the interior walls of the neck portion 16. In this position ( the "second state") the two compartments (the first and the second compartment) come into fluid contact with each other. This raises the partition wall 22 away from the neck portion 16 allowing the second component 62 to fall towards the first compartment 18. In this state, the cover 48 is retained on the cover so that the mixture and the nozzle 42 remain sterile Shaking, shaking or turning, represented by the arrow 68, the dry formula 62 and the liquid 60 are mixed with one another to produce a liquid formula 70. By removing the lid 48, the liquid formulation can be dispensed through the opening 64. of the nozzle "42. Figures 6 and 7 show another embodiment of a two compartment container, generally designated 310, in which an intermediate seal is externally controlled by rotation of a threaded displaceable member.The two compartment container 310 includes a cover 312 having a restricted neck portion 318 which defines a first compartment 314 and a second compartment 316. The first compartment 314 and the second compartment 316 intercommunicate in the restricted neck portion 318. The second compartment 316 has an opening 320 which has a threaded portion 322 around its periphery.The two compartment container 310 also includes an elem The stopper or displaceable member 324 which is shown separately in detail in Figure 8. The displaceable member 3324 has a threaded portion 326 for rotatably coupling the threaded portion 322 and a separation wall 328 for sealing the neck portion 318. The displaceable member 324 is formed such that, when rotated and the threaded portion 326 interacts with the threaded portion 322, the separation wall 328 moves from a non-watertight position (second state) as shown in Figure 7 in the FIG. wherein the first and second compartments 314 and 316 are intercommunicated to a sealing position (first ^ state) as shown in Figure 6 in which the neck portion 318 is sealed. Typically, the partition wall 328 is formed to complement the neck portion 318 and includes a resilient seal ring 334, formed of silicone or the like, 5 fitted between opposing parts of a molded plastic assembly. Alternatively, flat or stop surfaces formed can be provided to seal the neck portion 318. The fluid-tight seal formed by the partition wall with the portion of Or 10 neck can be reformable, being this, the two compartments are resellábles. Alternatively, the partition wall and the neck portion may be configured so that the seal can not be reformed. 15 It is a preferred feature of certain modalities Or of the present invention that. the displaceable member 324 also has a conduit 330 to allow the introduction of a component q through the opening 320 into a second compartment 316 when the The displaceable member 324 is in the sealing position. The at least one conduit 330 is preferably circumscribed by the threaded portion 326 of the displaceable member 324. Thus, "the displaceable member 324 as shown has a portion 326 substantially cylindrical with four conduits 330 separated by longitudinal radial walls. The longitudinal radial walls connect the separation wall 328 with the threaded portion 326. Alternatively, the conduits may be peripheral to the displaceable member 324 as perforations or channels in the threaded wall (not shown). The two-compartment container 310 in this case also includes a secondary seal 332 for sealing the conduits 330. In an alternative additional implementation of the present invention (not shown), the displaceable member 324 may be of solid construction. In this case, a separate sealable opening is provided to allow filling and / or assortment of the second compartment 316. It is a particular feature of some embodiments of the present invention that the displaceable member 324 may be moved or rotated to selectively seal or open the neck portion 318 from outside the two compartment container 310. To allow the displaceable member 324 to be taken for this purpose, the displaceable member 324 may have an upper wall section 336 that extends beyond the threaded portion 326. Manual rotation of the displaceable member 324 is facilitated by a flange member 338 which is fixed around the outside of the section. of top wall _336. The assembly and filling procedure ~~ of the two compartment container 310 is essentially the same as that described with reference to the bottle 10 of Figures 4-5. - Specifically for formula feeding applications for infants, the container of two compartments also preferably serves as a bottle for food. To this end, the two compartment container is provided with a feed nozzle fixed around the exterior of the displaceable member. In the case of Figures 6 and 7, the flange member 338 can be mounted externally to the feed nozzle 340 and secondary seal 332 both can be external. This allows the secondary seal 332 to serve multiple functions, sealing the second compartment, 316, protecting the sterility of the feed nozzle 340 and attaching to a shoulder of the second compartment 316 so that it acts as an aperture indicator wrapper to ensure that the brida 338 has not been opened. Figures 9A-9C show the construction steps in the filling of a two compartment container 80 according to a different embodiment of the invention. The container 80 is formed of a generally tubular body 82 with an opening 84 at one end of the body constituting the bottom of the container and a second opening 86 at an opposite upper end. Between the upper and lower ends there is a restricted neck portion 88. The containers 10, 310 and 80 have been formed with a restricted neck portion, the neck portions of these containers can also be formed as described with reference to the Figure 13. The movable member 90, has an end wall 92 with a sealable fill opening 94 and a partition wall 96 dependent on the end wall 92 by the pins 98, is fitted at the end 84 by threading in its peripheral portion. 10_0. As a result of this threading, the displaceable member 90 rotates causing the axial displacement of the separation wall 96 with respect to the neck portion 88. After engagement of the displaceable member 90 with the body 82, and in particular the partition wall 96 forming a fluid-tight seal with the neck portion 88, a first component 101, e.g., water, is introduced through the opening 94, which is then "sealed by the plug 102. The container is rotated to the position shown in Figure 9B, with opening 86 upwards, then a second component 104, for example, powder formula, is introduced through opening 86 which is sealed by closure assembly 106. The assembly of closure 106 may be provided with a resealable closure 108. The preparation of container 1 of Figures 9A-9C for use in the assortment of the formulation is shown in Figures 10A and 10B. In a first step, shown in Figure 10a, the movable member 90 is rotated so that the separation wall is separated from the neck portion 88 to allow the mixing of the components 110 and 104 to produce the liquid formulation 110. After Mixing and homogenization, the container can be rotated to fill through the closure 108 as shown in Figure 10B. Another embodiment of container 120 is shown in Figures HA-11F. The container 120 is similar to the container 80, shown in Figures 9 and 10, and also the filling form, with a "difference residing in the assembly 122 which allows dosing the liquid formulation 124. Figures HA to 11F show different steps in the preparation and assortment of the formulation The assembly 122 defines a compartment 126 formed between the lid 128 and the bottom wall 130 of the assembly 122. The lid 128 forms a fluid-tight seal with the upper end of the assembly. 122 has a skirt 132 which engages the rope 134 in the opening of 1 container 120. The assembly further has openings 136 which in the position shown in Figures HA-11C, provide communication between the compartment 126 and the interior space 138 of the container 120. After mixing the two components, as shown in Figure 11B, the container is rotated and consequently the liquid formulation fills the compartment 126 through d ". the openings 136 (Figure 11C) The assembly 122 is rotated so that the openings 136 are closed (Figure 11D) and the container 120 can be placed upwards (Figure HE) The side wall 131 of the closure assembly forms a fluid-tight seal reformable with the cover to prevent the liquid formulation or any of the separate components from "leaving the container. Hoop seals 133 can be provided to form or assist in the formation of the fluid tight seal. Then the lid 128 can be removed and the contents of the compartment 126 can be filled (Figure 11F). Another embodiment of a container 150 is shown in Figures 12A-12E. Again, this container 150 differs from the container 80 and 120 in the nature of the closure and assortment assembly 152. The manner of dispensing is shown in Figures 12A-12E. The dosing assembly 152 has an end wall 155 with a dependent skirt 153 along its peripheral edge which has threaded cords 151 which engage with the cooperating screw cords 154 in the opening of the container 150. end 155 has an opening 156 which has a cylindrical central tube 158. A fluid tight seal is provided between the central tube 158 and an end wall 155 so that neither the components nor the mixed liquid formulation leaks container. The central tube 158 opens and communicates with a dosing compartment 157. The compartment 157 is sized to contain an appropriate and predetermined amount of the liquid formulation. The upper part of the compartment 157 is formed with a number of small recesses 159 which are configured to allow the liquid formulation to enter and be trapped in the dispensing compartment 157. The cap 149 is provided in the central tube 158 and provides a seal Hermetic to the fluids. In Fig. 12A, the two-compartment container stores the two components separately, in this case a dry powder in the upper compartment and a liquid in the lower compartment, until the liquid formulation is prepared.When the liquid formulation is going to be In this embodiment, the movable member is moved so that the lower and upper compartments intercommunicate as shown in Figure 12B.The entire container can be moved, such as by shaking or shaking, to "facilitate the preparation of the liquid formulation. . In Figure 12C, the container is turned upside down and the liquid formulation flows through small gaps 159 into the dosage compartment 157. When the dosage compartment is full, the container is turned to its standing position as shown in FIG. Figure 12D. The lid 149 is removed and the liquid formulation is dispensed through the central tube 158 as shown in Figure 12E. Since the central tube 158 has a larger cutting section and an opening than the small recesses 159, the quantity dispensed in the dispensing compartment 150 is supplied in Figure 12D before the small recesses 159 allow additional liquid formulation within the dosage compartment 157. Another embodiment of a container 160 is shown in Figures 13-C as an infant feeding bottle 160 having a body 162 and a bottom end 154. A movable member 170 is formed with a bottom portion 172 having a central opening 174 sealed by a plug 176 and having a partition wall 178 connected to the bottom portion 172 by means of "a cylindrical wall 180 formed with openings 182. Instead of a restricted neck portion., the cover 162 has a radial wall 184 extending inwardly defining a neck portion 185 which cooperates with the partition wall 178 to provide a fluid tight seal between an upper compartment 190 and a lower compartment 192 in the condition shown in Figure 13B. In Figure 13, the cover 162 accommodates a sleeve 183 which is its upper part having an inwardly extending radial wall 184 which cooperates with the sealing annular 186 in the partition wall 178 to form the seal airtight. fluids The seal may be reformable (this being resealable) or is constructed to form a seal which can not be reformed after the partition wall is decoupled from the neck. The displaceable member is moved axially to the "position" presented in Figure 13C so that the compartments 190 and 192 come into fluid communication with each other.The liquid formulation can then be mixed and dispensed through the nozzle closure which can be constructed as described above or in accordance with the forms known in the art The bottom end 164 in Figures 13A-C is formed with a helical groove 166. The groove 166 slidably accommodates the knob 168 which causes the axial displacement of the displaceable member 170 by the rotation of the knob 168 between a first position, marked with the word "OFFICIAL", where the knob is placed in the Figure 13A and 13B, and a second position, marked by the word "ON". ", presented in Figure 13 A. Details may be provided in the slot 166 to retain the knob 168 in either the" on "or the" off "position. an infant feeding bottle 200 is shown in Figures 14A-B having a cover 202 which is generally cylindrical and has a restricted neck portion 204. The inwardly projecting neck portion 204 is an annular engagement member 206 formed with a downwardly facing groove 208 which cooperates with an annular projection 210 projecting from the partition wall 212 to provide a fluid-tight seal between the lower compartment 214 of the container and an upper compartment 216 as shown in FIG. Figure 14A. The partition wall 212 forms part of the movable member 218 which has a user-manipulable portion 220 with two pins 222 accommodated within a helical groove 224. By rotation of the manipulable portion 220, this movable member is displaced axially downwardly. to the position shown in Figure 14B. The movable member further has a bottom portion 226 having an opening sealed with a plug 228. The partition wall 212 is connected to the bottom portion 226 by means of a cylindrical wall 225 having openings 227. The plug 228 allows a component, e.g. infant powder formula, to be introduced into the bottom compartment 214. The infant feed bottle 200 has an opening 238 with a nozzle 230 with the nozzle protected by a cover 232 which can be fixed to the cover by a stroke adjustment or cooperating with threaded portions. The upper compartment 216 in the embodiment of Figures 14A and 14B has the specific dimensions for storing the liquid and / or fluid substance while the lower compartment 214 has the dimensions for storing the dry substance. It is envisioned that certain advantages and improved mixing may result from a liquid and / or a fluid added to the dry substance in the lower compartment. For example, storing the powder in the compartment 216 can lead to clogging of the nozzle by undissolved dust. An exploded version of Figures 4a-b is shown in Figure 4C. Deck 202 is constructed by the main tank assembly 250having a neck portion 204 and an annular coupling member 206 projecting inwardly, with the nozzle seat 260 by ultrasonic welding so that the main tank 250 and the nozzle seat form a fluid-tight compartment. 216. The opening 238 in the upper end of the cover 202 is equipped with the nozzle 230 which is held in place by the nozzle adjusting ring 240. The nozzle adjusting ring ^ 240 engages with the shoulder 234 formed in the nozzle 230 and is retained in place by the protuberances 236 formed in the nozzle 230 and by the lip 262 formed in = the nozzle 260. The nozzle retaining ring 240 engages the nozzle 230 of the container by snap fit on the lip 262. The nozzle assembly 230 on the cover 202 with the nozzle retaining ring 240 is designed so that the container is for one use only. For example, the nozzle retention ring 240 can be designed to fit by beating the lip 262 in a way that if the ring is removed, it can not be placed back into the container. Alternatively, or in addition, the nozzle retaining ring 240 can be designed so that it can not be removed after it has been adjusted in place in the nozzle seat 260. Other attributes of the container which make it particularly adaptable for a single use are its materials and ease of construction, and the thickness of the materials used. FIGURE 14C also shows the movable member 218 with a manipulable ring portion 220. The movable member 218 is inserted into the bottom end of the cover 202 and the manipulable portion 220 is fitted over the bottom end of the cover 202 and placed so that the bolts 222 are inserted into the helical groove 224 and are slammed through the openings 225 in the movable member 218 to secure the manipulable portion 220 to the movable member. Depending on whether the container is for single use or for multiple uses the seal formed by the annular projection 210 (or partition wall 212) and slot 208 (in the annular coupling member) can be designed to form a seal single use or a "reformable" seal (this being resealable.) In some applications it may be desirable to have the container constructed specifically for single use in order to ensure container sterility (and nozzle arrangement) and proportions Correct, sterility and quality of the components In the embodiment of Figures 14A-C the annular projection 210 and the slot can be configured and adapted for single use by means of, for example, ultrasonic welding of the two where the The welded joint is separated with the movement of the displaceable member 218. The annular projection and the groove can also be configured and adapted to be resealed, that is, the seal can be broken and reformed by r the movement of the displaceable member. It can be seen that the filling of the container of Figures 13 and 14, its preparation for use and assortment is similar to the embodiment described in Figures 9A-C and 1 OA- and B. An infant feeding bottle 410 according to another embodiment of the invention is shown in Figure 15. The container comprises a cover 412 of a generally cylindrical shape with side walls 414, a bottom wall 416_ and an opening 418 in its part upper with a closure assembly 420. Fixed at the bottom end of the container is a tamper-resistant cover 421, 1 function of which will be further explained below. The closure assembly 420 comprises a nozzle 422, typically made of silicone rubber, latex rubber or any other FDA-approved material adaptable for such purposes, having an annular skirt 424, mounted on, a seal member 426 having an annular portion 428 defining a central opening 429 equipped with a screen element 430 to filter undissolved food particles of the liquid formula, and having a cylindrical ring projecting upwards 431 supporting the lower interior face of the nozzle 422 and the inclined support structure or legs 432. The edges of the annular portion 428 are received by the peripheral circumferential shoulder 434 at the upper end of the side walls 414 and the end of the support structure 432 rests on the inner side of the side walls 414. The nozzle is retained by a coupling member 436 having a generally stepped sectional cutting shape. The coupling member 436 has a first horizontal portion 442 pressing the skirt 424, a second annular horizontal portion 444 that rests in a peripheral slot 446 of the seat member 426, and a downwardly extending peripheral portion 448 that engages in a stroke to the shoulder 43'4 by means of the annular protrusion 450. This manner of coupling by means of the coupling member 436 ensures a tight fixation of the closure assembly 42O to the opening 418. The sealing of the coupling can sometimes be improved by, the use of an annular ring placed below the horizontal portion 444, _ etc. As described with reference to Figures 14A-C, the nozzle assembly can be configured and adapted so that the container is particularly suitable for single use, such as, for example, designing the coupling member to be non-removable or non-removable. suitable to be readjusted. As can be seen further in Figure 15, the closure assembly 420 is equipped with the cover 452 having a cover member 454 projecting downwardly receiving the upper end of the nozzle 422 thereby sealing the opening 456. The container it has two compartments, an upper compartment 460 and a lower compartment 462 separated by a partition wall 464 - integrally connected to the side walls 414 through the annular connection area 466. "Extending downwardly from the partition wall 464 there is a elongated connecting member 468 having a hollow cavity 470 with an opening 472 at its upper end and having reinforcing ribs 474. The bottom end of the elongate member 468 is received by and connected to a projecting 476 cup member upwards from the bottom wall 416. The partition wall 464 ^ provides a tight separation between the compartment 460 and the compartment 462. P or the vertical displacement as a result of an upward push of the bottom wall 416, the connection zone 466 is broken thereby unifying the two compartments and allowing the mixing of their contents. The seal formed in this embodiment by the partition wall 464 is not reformable and the container is -particularly adapted for a single use. In order to prevent accidental displacement of the bottom wall 416, "it is covered by an alteration resistant cover 421 which has to be removed to allow the bottom wall 416 to be pushed. The cover to the movement 421 may be removably coupled by the use of an adjustment adjustment per blow, by screw coupling, "by a releasable area, etc. Alternatively, the tamper-resistant cover can also be a removable film before use.

Figures 16A-16B illustrate the manner of preparation of the container, so that each compartment contains a component of the formula for infant, for example, powdered formula in the bottom compartment 462 and water in the top compartment 460. However, this "obviously can be inverted, this being, the powder formula above and the water down.The container is typically provided initially in the manner shown in Figure 16A without the bottom wall 416 and the closure assembly 420 and ^ positioned inverted. In a first step, shown in Figure 16B, the compartment 462 is filled with a dry powder formula 490 introduced through the open end 492 by means of the dispensing nozzle 94. In a next step, shown in Figure 16C, the bottom wall 416, having a concave shape within the annular skirt portion 496, is mounted on the open end 492 of the container and attached thereto. Preferably, the skirt portion is ular 496 is fixed to the inner face of wall 412 by sonic welding, although other forms of adhesion such as gumming or heat welding, etc. are also possible. The cup member 476 is fixed to the bottom end of the elongated member 468 by sonically welded typically preformed by inserting a probe 497 through the opening 418 of the container and the opening 472 of the cavity 470. In the next preparation step, shown in FIG. Figure 16D, an alteration resistant cover 480 is mounted on the end 492 and the container is turned to its standing position and the liquid (typically water) 498 is introduced into the compartment 460 through an assortment valve 400. Then, in a next step, shown in Figure 16E, the closure assembly 20 is fitted over the opening 418. The preparation of the container for use is shown in Figure 16F. Prior to use, the tamper resistant cover 480 is removed from the bottom end of the container and force is applied in the vertical direction in the bottom wall 416, as represented by the arrow 404, causing the wall 416 to assume the position as it is presented in Figure 16F, giving an axial vertical displacement of the elongate member 468 and the partition wall 464. This tears or breaks the partition wall 464 in the connection area 466 whereby the contents of the two compartments can be mixed (represented by arrows 404). After mixing, the formulation is ready for use and assortment through the opening 456 of the nozzle 422 after removing the lid 452. Reference is now made to Figure 17 showing a bottle for infant 510 feeding according to another embodiment of the invention. This modality is essentially similar to the modality shown in Figure 15 with all the same elements with reference numbers with the last two digits being the same as the corresponding element in Figure 15. In distinction with the bottle of Figure 15, the bottom wall 516 in Figure 17 is turned upwardly having an integral knob 580 confined within the space defined by the base member of the bottle 582. As shown in Figure 18, when the knob 580 is pulled down in the direction of the arrow 586, the wall 516 is activated downward with the displacement causing the fracture or tearing of the connection zone 566 allowing the mixing of the contents of the two compartments, similarly as in the embodiment of Figures 15 and 16. The knob 180 has several coupling teeth 584 which serve, as can be seen in Figure 17, for engagement with the accessory wall 588, to retain a bottom wall 516 and n the activated position down. Once the two compartments have been mixed, and a ready-to-use formulation is formed, it can be dispensed through the opening 556 of the nozzle 522 after removing the cap 552. It should be appreciated that the present invention can be used with advantage for_ a wide range of implementations of a two compartment container. Possible implementations include, but are not limited to applications in food, beverages and pharmaceuticals, and can use two liquid components or one liquid and one solid. Furthermore, it should be appreciated that in some embodiments the invention may also be directed particularly towards pre-packaged containers of two or more single-use compartments which are easily and economically constructed and filled in order to be disposable. The container may also have specific characteristics for a given application to supply the final mixture. Possibilities include, but are not limited to, feeding devices for infants or geriatrics and rates for measurements or other devices to supply measured units for medicines and the like. As an example only, the present invention has been illustrated some examples with respect to a bottle structure for infant feeding and in other examples to a dairy assembly. It is significant to note that the containers of the present invention can be filled under a variety of controlled conditions suitable for a wide range of applications. The entire assembly process can be carried out under sterile conditions and can use sterile components and ingredients. In addition, one or both compartments, and particularly the compartment containing "a powdered ingredient, can be partially evacuated." Alternatively, or additionally, an inert gas such as nitrogen, either above or below atmospheric pressure, can be introduced to minimize _the oxidation of the contents during storage Other special environmental conditions such as controlled humidity may also be employed as required.In cases such as formulas for infants in which the mixture may require to be heated to ensure dissolution or assortment, the The two-compartment container can be made entirely of non-metallic materials to allow direct heating of the contents in a microwave oven.Alternatively, or in addition to, the two-compartment container can be made entirely of materials to allow the heating of the contents by placing the container in a liquid h Irrigating or hot such as water. Many materials can be used in the construction of the different embodiments of the invention including plastics such as, for example, polypropylene. The feed nozzle and portions of the separation wall can be made of silicone rubber. When used to store or stock medications or foods, it is contemplated that container materials meet regulatory standards such as the United States Food and Drug Administration (FDA) and other regulatory authorities. It can be appreciated that the foregoing descriptions are intended to serve as an example only, and that many other embodiments are possible and are comprised within the spirit and scope of the present invention.
