DETAILED DESCRIPTION OF EMBODIMENTS

(30) FIG. 1 shows a bottle 10 having a side wall 12 configured for holding fluids, such as water. The side wall 12 includes a rigid portion 12a having an opening 15, and a flexible portion 12b, having a corresponding opening 17 coupled to the opening 15 of the rigid portion 12a, thereby forming together an enclosed structure for holding fluids therein. The rigid portion 12a includes a neck portion 14 having a mouth 16. The rigid portion 12a can be made of resin material such as plastic, High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Polyethylene Terephthalate (PET, PETE or polyester) Polyvinyl Chloride (PVC) Polypropylene (PP) Polystyrene (PS), Fluorine Treated (HDPE) Post Consumer Resin (PCR), K-Resin (SBC), Bioplastic, etc.

(31) The flexible portion 12b is configured to be folded inside the rigid portion 12a for example when the bottle 10 is empty, as explained hereinafter. The flexible portion 12b can be made of flexible thermoplastic materials, such as polyolefin, in particular PP, LDPE, LLDPE, and PA, PVC, PMMA, or lamination sheets, such as BOPP and POPET.

(32) As most clearly shown in FIG. 1C the flexible portion 12b can be coupled to the rigid portion 12a by welding the periphery of the corresponding opening 17 to an inner surface of the rigid portion 12a. The rigid portion 12a can include a skirt 19 disposed about the outer periphery of the opening 15, the bottom of which slightly protrudes outwardly. The periphery of the corresponding opening 17 of the flexible portion 12b is folded outwardly and down and is welded to the inner surface of the skirt 19. This way, as shown in FIGS. 2B through 2C, when the bottle is in its folded position the flexible portion 12b extends inside the rigid portion 12a. The wall of the flexible portion 12b can be configured to be disposed adjacent the inner surface of the wall of rigid portion 12a.

(33) On the other hand, when the bottle is in its deployed position, as shown in FIGS. 1A through 1C, the flexible portion 12b extends downwardly from the opening 15 outside the rigid portion 12a thereby expending the inner volume of the bottle 10. Thus, the periphery of the corresponding opening 17 is attached to the inner periphery of the skirt 19, and the remaining of the flexible portion 12b is free to extend outwardly.

(34) According to the illustrated example, the rigid portion 12a is defined at the upper portion of the bottle 10, and the flexible portion 12a is defined at the bottom portion thereof. In order to provide the bottle 10 with stability and to allow standing the bottle in an upright position, the bottle is further provided with a support member affixed to the rigid portion 12a. According to the illustrated example, the support member 20 includes three legs 22, coupled to the rigid portion 12a. Although in the illustrated example the legs 22 extend form the skirt 19, it will be appreciated that the legs can be coupled to any other section of the rigid portion 12a.

(35) The support structure 20 can be integrally formed with the rigid portion 12a or can be coupled thereto by welding gluing, etc. Alternatively, the support structure 20 can be a separated element which is detachably attached to the rigid portion 12a. For example, the support structure can be formed with the skirt 19 from which the legs 22 extends. The skirt 19 can include a ring portion 24 which is configured to be disposed over the outer periphery of the opening 15 of the rigid portion 12a. The diameter of the ring portion 24 is such that when it disposed over the outer periphery the ring portion applies inward radial compression forces thereby maintaining the coupling between the support structure 20 and the rigid portion 12a.

(36) The support structure 20 can be detached from the rigid portion 12b, by forcefully pulling the ring portion 24 off the rigid portion 12a. This way, the support structure can be removed by the user, for instance, before disposal of the bottle, and can be reused on another bottle.

(37) According to one example, the support structure can be provided with a ring portion as described hereinabove, which can be further welded to the outer periphery of the opening 15 of the rigid portion 12a, thus, providing the bottle with additional stability and rigidity.

(38) The bottle 10 can be further provided with a flange 21 defined about the outer circumference of the mouth 16. The flange can be used for gripping the bottle 10 by a robotic arm, such as used in a dispensing machine. The robotic arm having a corresponding gripping member can be used to lift the bottle 10 by inserting the gripping member underneath the flange 21.

(39) Referring now to FIGS. 3A and 3B, a plurality of bottles 10 in the folded position can be stacked up one inside the other, while the flexible portion 12b of each one extends inside the rigid portion 12a thereof. In order to provide an optimal space usage the rigid portion 12a includes an diameter which is slightly gradually increasing from the neck portion 14 on one end of the rigid portion 12a towards the opening 15 on the other end thereof. This way a rigid portion 12b of one bottle can be disposed inside the rigid portion of a consecutive bottle in the stack. In addition, in order to allow the support member 20 of one bottle to be disposed inside the support member of the consecutive bottle, the legs 22 can be formed with some flexibility, obviously without compromising on the stability thereof.

(40) The flexible portion 12b can be such which when in the folded position it extends inside the rigid portion 12a, adjacent the inner wall thereof such that a rigid portion of another bottle can freely slide in and out. Further, in order to maximize the use of space when in the folded position, the flexible portion is made such that when in disposed in the folded position the top end thereof disposed inside the rigid portion reaches the neck portion 14 of the bottle 10. This way, the rigid portion of a first bottle in the stack can be disposed inside the rigid portion of second bottle with the mouth 16 thereof reaching almost at the neck portion of the second bottle.

(41) FIGS. 3C and 3D illustrate a bottle 25 constructed in accordance with another example of the presently disclosed subject matter. Bottle 25 includes a rigid portion 23 having an opening 23a, a flexible portion 26 having a corresponding opening 26a, and a support structure 27 substantially similar to those of the previous example. The flexible portion 26 according to this example is coupled to the rigid portion 23 by fastening thereof to the rigid portion together with the support structure 27. Fastening the support structure 27 and the flexible portion 26 to the rigid portion 23 can be carried out by a snap coupling arrangement. The opening 23a of the rigid portion 23 can be provided with a coupling portion 29a defined about the circumference thereof and configured to receive therein a corresponding coupling portion 29b defined on the support structure 27. Corresponding coupling portion 29b is configured for snap coupling with the coupling portion 29a, thereby coupling the support structure 27 to the rigid portion 23. The circumference of the corresponding opening 26a of the flexible portion 26 is inserted between the coupling portion 29a and the corresponding coupling portion 29b, thus when the coupling portions are snap coupled to one another the flexible portion 26 is fastened to the rigid portion. It is appreciated that the snap coupling arrangement of the coupling portion 29a and the corresponding coupling portion 29b can be configured to provide a fluid tight sealing arrangement therebetween. Thus, the rigid portion 23 and the flexible portion 26 form together a fluid tight container.

(42) FIG. 4A trough FIG. 4D illustrates a bottle 30 in accordance with another example of the presently disclosed subject matter. Bottle 30 is substantially similar to bottle 10 of FIGS. 1A through 2C, and includes a flexible portion 32 coupled to a rigid portion 34, and having a support structure 36. The support structure 36 according to this example includes three legs 37 each extending from a ring portion 38 mounted on the rigid portion 34 and having an extension 39 defined at the bottom end thereof. The extension 39 protrudes outwardly with respect to the bottle 30 and configured to provide the support structure 36 and, hence, the bottle with an additional stability.

(43) FIGS. 5A through 5D illustrate a bottle 40 in accordance with yet another example of the presently disclosed subject matter. Bottle 40 is substantially similar to bottle 10 of FIGS. 1A through 2C, and includes a flexible portion 42 coupled to a rigid portion 44, and having a support structure 46. The support structure 46 according to this example includes three legs 47 each extending from a ring portion 48 mounted on the rigid portion 44 and coupled to a base member 43 disposed at the bottom of the bottle 40 underneath the flexible portion 42. It is appreciated that according to this example, since the base member 43 provides the bottle 40 with stability, the legs 47 can be slightly thinner than those of the previous examples. In order to allow the bottles to be stacked up on inside the other, the base member can be in a shape of a ring having a large aperture 45 at the center thereof. The aperture 45 has a diameter which is larger than the diameter of the rigid portion 44 and the ring portion 48, thus allowing another bottle to be stacked up one inside the bottle 40. Alternatively, the base member can be a separated element on which the bottle 40 is placed. For example, the base member 43 can include a seat (not shown) for the legs 47, such that when the bottle is used the legs 47 can be disposed in the seat and when it is desired to stack up bottles, the base member 43 is removed.

(44) According to an example, the support structure can be a cylindrical member or conical member extending from the rigid portion to the bottom end of the flexible portion, such that when in the deployed position the container can be disposed in the upright position, supported by the cylindrical member or the conical member. The support member can be such which is detached from the rigid portion and can serve as a seat for the container.

(45) According to an example the container can be a container assembly having a container and a standalone support structure. The container includes a rigid wall and a flexible wall portion such as described herein above, the support structure can be any of the support structure described hereinabove or herein after and can be configured as a separated element on which the container can be disposed.

(46) The base member 43 can further include a concaved plate disposed substantially at the center thereof, and configured to hold the bottom end 42a of the flexible portion 42 when in the deployed position. The bottom end 42a of the flexible portion 42 can be rounded having a radius which is substantially similar to or smaller of that of the concaved plate, so as to allow the flexible portion to be stably disposed on the base member 43.

(47) FIGS. 6A through 6C illustrate a bottle 50 in accordance with another example of the presently disclosed subject matter. Bottle 50 includes a flexible portion 52 coupled to a rigid portion 54, at one end thereof and to a rigid neck portion 56 on the other end thereof. According to this example, the flexible portion 52 is disposed at the upper portion of the bottle, while the rigid portion 54 is disposed at the bottom portion thereof. This is as opposed to the previous examples, wherein the rigid portion is disposed at the upper portion of the bottle while the flexible portion is disposed at the bottom portion thereof.

(48) According to this example, in the folded position, the flexible portion 52 is folded inside the rigid portion 54 such that the neck portion 56 is disposed substantially at the bottom of the rigid portion. As shown in FIG. 6C a plurality of bottles 50 can be stacked up one inside the other by inserting the rigid portion of one bottle inside that of another bottle while the flexible portion is folded therein. The bottom of the rigid portion 54 of a first bottle can be disposed substantially on top of the neck portion of the second bottle inside which it is stacked up.

(49) According to one example, the bottle can be provided with a filling valve (not shown), for example at the bottom of the rigid portion 54. This way, the bottle can be filled by an automatic filling system through the valve, while the neck portion 56 can include a mouth cover with a cap.

(50) Referring now to FIGS. 7A through 9B, in order to allow an automatic filing of any one of the bottles described hereinabove, the cover on the mouth can be provided with a filling valve. In FIG. 7A there is shown a bottle cap 60 having a filling valve 62 in the form of an aperture 64. A sealing disc 66 is disposed on the aperture 64 and is mounted to the periphery thereof. The disc 66 includes a cut 67 at the, for example along the center thereof, which is configured to allow a filling pipe 68 to be inserted therein, as shown in FIG. 7B. When the pipe 68 inserted through the cut 67, the disc 66 is deformed and the area of the disc around the cut is urged inwardly, thus allowing the insertion of the pipe inside the bottle. When the pipe 68 is removed the disc 66 is urged back to its original form where the cut is sealed by the adjacent sides of the disc. It is appreciated that the cut can be formed in to perpendicular directions, thus facilitating the insertion of the pipe therein.

(51) FIGS. 8A and 8B illustrated another example of a bottle cap 70 having a filling valve 72 in the form of an aperture 74. Similar to the previous example the valve 72 includes a sealing disc 76 disposed on the aperture 74. However, according to this example the disc 76 is mounted on the two opposing sides at the periphery thereof, while on the other portions of the periphery of aperture 74 the disc 76 is free to deform inwardly.

(52) FIGS. 9A and 9B illustrates a further example of a bottle cap 80 having a filling valve 82. According to this example the filling valve is in the form of a port 84 having a slidable cover thereabout, such as known as a sport cap bottle. When the port 84 is in its open position a quick filling of the bottle can be carried out by coupling a filling pipe to the port 84.

(53) According to one example, filling of the bottle can be carried out through an aperture extending through the rigid portion, for example the mouth of the bottle. The aperture can be covered with a breachable membrane. The membrane is resiliently configured such that when it is breached, for example by punctuating a filling needle therethrough, the membrane rebounds to a breached state. When the filling needle is removed the membrane is rebounded back to its original unbreached state covering the hole formed by the needle.

(54) Further attention is drawn to FIG. 10, showing a stack of bottles 90 having a plurality of bottles 92, such as the bottle of FIG. 1A, having a rigid portion 92a, a flexible portion 92b and a support structure in the form of legs 94 extending downwardly. The stack 90 can be disposed in a cartridge 100 of a dispensing machine (not shown). The bottle are configured to be extracted from the cartridge 100 by an extraction mechanism, which according to the illustrated example is in the form of a helical spring 104 rotating about it axis. The legs 94 include a slight outwardly extension 95, such as described herein above with regards to the extension 39 of the bottle 30 of FIG. 4. The helical spring 104 is configured to engage the extension of the bottommost bottle 92 in the cartridge 100 and by rotating to urge the bottle downwardly. In order to facilitate the extraction process the extraction mechanism can be provided with a pair of helical springs 104 disposed at two substantially opposite sides of the cartridge 100 and configured for simultaneously rotating, thereby engaging the legs 94 of the bottle 92 and extracting it from the cartridge. It is appreciated that the bottle can include other means allowing it to be extracted rather than the extensions 95. For example the leg can include ridges defined along the length thereof. In addition, it is appreciated that the extraction mechanism can include any other means for extracting the bottles from the stack 90, as known.

(55) Those skilled in the art to which the presently disclosed subject matter pertains will readily appreciate that numerous changes, variations, and modifications can be made without departing from the scope of the invention, mutatis mutandis.
