Description

Field of technology to which the invention relates

The present invention relates to the field of devices for filling baby bottles with liquid food.

BACKGROUND OF THE INVENTION

Most types and designs of baby feeding bottles are designed to be reused and therefore require cleaning, at least as a means of preventing the development of unwanted pathogens. Responsibility for cleaning and sterilizing them rests with the parents or caregivers.

The inflatable containers associated with WO 2006129302 are disposable and can therefore help improve sterility when feeding the baby, and minimize contamination due to improper and/or careless user actions.

At the same time, the final preparation of formulas for feeding the baby by mixing is usually done at home. Thus, an inflatable container, such as that described in WO 2006129302, should allow the user to administer the mixture into the container at home in a simple and as sterile manner as possible. Therefore, a method for improving sterility during the final preparation and filling of baby formulas into disposable inflatable containers at home by unskilled people is required and is one of the objects of the present invention.

Making it easier for the user to complete the final preparation of formula for feeding the baby, as well as the process of pouring it into the inflatable container, is also an object of the present invention.

In a first broad aspect of the first category of solutions, the present invention is an example of embodiments of a device configured to receive pre-filled feed containers to facilitate squeezing the feed container (and in some embodiments also to facilitate mixing of the mixture contained therein before squeezing the feed container), by whereby the mixture contained therein is transferred from the supply container to the baby feeding device.

In a second broad aspect of the first category of solutions, the present invention is an example of embodiments of a device that allows a user to set a squeezable delivery container to a fill position in the device, as well as to stir baby formula (or preformed formula) ingredients into the delivery container before using a squeeze session to the prepared mixture to move it from the supply container to the baby feeding device.

With reference to embodiments of the apparatus according to both said first and second broad aspects, the electric emptying device comprises a mechanical means for holding a two-part structure comprising: (i) a compressible pouch pre-filled with liquid contents and said supply container; and (ii) an inflatable container representing said device for feeding a child; wherein the device further comprises a motorized emptying mechanism for emptying the compressible pouch, thereby discharging its liquid contents into the inflatable container.

With reference to embodiments of the device according to said first broad aspect, the device further comprises a housing and a door space within the housing configured to accommodate and support a two-part structure isolated from the external environment.

Although the squeezable pouch can only hold a limited specified volume, in various embodiments the door space is spatially sized to accommodate twice that volume: its top portion contains the squeezable pouch filled with a maximum specified volume of liquid contents, and its bottom portion contains the squeezable pouch filled with a maximum specified volume of liquid contents. an inflatable container filled with a specified specified volume. Thus, in such embodiments, the total volume of the door space is at least twice the volume transferred from the compressible disposable pouch into the inflatable container.

In preferred embodiments of the present invention, the door space has a hanging arrangement to hold the two-piece structure in an upright position, with the compressible bag at the top and the inflatable container at the bottom. In various embodiments of the present invention, the hanging device includes two spaced apart, horizontally oriented pins projecting into the door space near the top thereof. A compressible pouch for use in such embodiments will comprise a pair of spaced apart holes corresponding to the pins and allowing the pouch to be suspended from the pins. In this way, the package can be hung on pins by securing it inside the door space, the pins being respectively inserted through the holes.

In various preferred embodiments of the present invention, the door space includes in its middle portion a clamping device configured to grip the two-part structure at the junction between the compressible disposable pouch and the infant feeding device. In various preferred embodiments of the present invention, the clamping device includes a first semi-circular element protruding from the rear wall of the door space and a second semi-circular element protruding from the door of the door space, the two semi-circular elements being arranged so that when a two-part structure having a cylindrical joining area between a compressible disposable bag and a baby feeding device, suspended by a holder located near the top of the door space, said cylindrical connection area being located adjacent to the first semi-circular element and, after closing the door, being caught between the first and second semi-circular elements and held firmly by them, which together form a ring-shaped clamp that fits tightly around the cylindrical joint area of the two-piece structure.

In embodiments of the present invention that use either compressed air pressure to squeeze out a squeezable disposable pouch or a vacuum pump to inflate an inflatable baby feeding device (by providing negative external pressure therewith), the first and second semicircular elements are formed by semicircular recesses in opposing the edges of respective horizontal barrier portions, the first of which projects from the rear wall of the door space and the second of which projects from the door so that when the door is closed and the two-piece structure is within the door space, the edges of the horizontal barrier portions touch and align to form a sealed horizontal barrier between the upper region of the door space (where the compressible disposable pouch is located) and the lower region of the door space (where the inflatable feeding device is located), thereby minimizing the flow of fluid between the upper and lower regions of the door space. In these embodiments, the semicircular recesses together form a circular opening extending through a horizontal barrier, the opposite edges of which fit tightly around the cylindrical joint region of the two-piece structure when the door is closed. Since there is an opening in the barrier, there is only a fluid communication path between the upper and lower regions of the door space when it is filled with the cylindrical junction region of the two-piece structure, and fluid located outside the two-piece structure cannot flow between the upper and lower regions of the door space.

In the context of the present invention, said upper and lower door space regions will be referred to as the upper and lower door space compartments, respectively.

In various embodiments of the present invention, the inflatable container includes a connecting portion removably coupled to a corresponding connecting portion with which the compressible pouch is provided. After the connecting parts are joined together, the compressible pouch and the inflatable container are mechanically secured from accidental separation, and a fluid connection is provided through the connector between the compressible pouch and the inflatable container. The connecting part of the inflatable container (for example, the type disclosed in Fig. 2 WO2006129302) is proposed with a backflow prevention device, a valve, which allows fluid to flow from the compressible bag into the inflatable container, but prevents the flow of fluid from the inflatable container into the compressible bag (or outward, in case of detachment of the compressible package). The compression pouch connecting portion may include a pressure valve to prevent fluid from leaking from the pouch under internal or external pressure to which it is or may be subjected before the compressible container is attached to the inflatable container to fill it. In various embodiments, the compressible pouch is supplied together with common connecting parts and is connected therewith to the inflatable container and is thus closed by the valve of the inflatable container, to be released from it only after its liquid contents have been squeezed into the inflatable container. Thus, there is no need for the compressible package to contain a valve.

In various embodiments of the present invention, the electric emptying device is provided with an electric air pump configured to provide a pressure to the upper compartment of the door space above atmospheric pressure. Providing pressure will cause the compressible pouch to compress, forcing its liquid contents to flow through the joint into an inflatable container that is located in the lower compartment where the pressure is equal to or less than atmospheric pressure. In various embodiments of the present invention, the electric emptying device is provided with an electric vacuum pump configured to provide negative pressure (pressure less than atmospheric pressure) to the lower compartment of the door space. Providing a vacuum will cause the liquid contents to be sucked from the compressible bag and forced to flow through the connection into the inflatable container, which is located in the lower compartment, where the pressure is less than the pressure in the upper compartment. In preferred embodiments of the present invention, an electric emptying device is provided with an electric pump configured to suck air from the lower compartment and deliver it to the upper compartment, thereby providing negative pressure (pressure less than atmospheric pressure) to the lower compartment of the door space while simultaneously providing for the upper compartment pressure is higher than atmospheric pressure. Due to the pressure difference between the upper compartment and the lower compartment, the liquid contents will be forced through the connection from the compressible bag into the inflatable container.

In preferred embodiments of the present invention, activation of the pumps is ensured only when the door of the door space is closed. These embodiments provide a door switch device with normally open contacts that remain open whenever the door is opened, thereby cutting off power to the pump. Closing the door turns the switch on and activates the pump.

The design of the switch may be mechanical (eg, push-button) or electronic, such as optically actuated (the state of the door is determined by an optical means, such as a photocell), magnetically actuated, capacitively actuated, or inductively actuated. According to the door switch inactivation type

In various embodiments of the present invention, the compressible container is made from the same portion of material as the inflatable container and is a stretched inflatable container until the inflatable container is separated from the compressible pouch by a fluid sealing means, whereby it is released from the liquid connection with the compressible package.

The inflatable container has a tensile outer wall configured to expand when liquid under pressure is introduced into it from a compressible bag.

Said release of the liquid connection between the compressible bag and the inflatable container occurs after the inflatable container has been filled by introducing liquid squeezed out of the compressible bag.

In various embodiments, the liquid sealing apparatus comprises a pressing member configured to seal the inflatable container by applying pressure to the outer sides of the extensible wall, thereby holding the opposing inner surfaces thereof together, leaving no space for liquid between the opposing inner surfaces of the extensible wall in its regions , compressed by a squeezing device.

In some embodiments, the outer squeeze device is moved in proximity to the tensile wall while causing any gaps therebetween to be closed so that liquid contained between opposing internal surfaces of the tensile wall is pushed out of the closed gaps.

In some embodiments, the squeezing device is configured to be displaceable along the extensible wall from a distal end of the compressible pouch portion of the two-piece design more distal from the compressible container portion to a proximal end of the two-piece compressible pouch portion proximal to the inflatable container portion.

In some embodiments, the squeezing device is configured to hold a distal end of a portion of the compressible pouch of the two-piece design more distant from the portion of the inflatable container, thereby allowing the compressible pouch to be wound around the squeezing device from its distal end to its proximal end proximal to the portion of the inflatable container.

By relative movement between the squeezer (either by displacement or rotation) and the compressible pouch in the direction from the compressible pouch portion of the two-piece design to the inflatable container portion of the two-piece design, the liquid contained in the compressible pouch is pushed out of the closed gaps toward the inflatable container and all still spaced apart parts of the wall of the compressible package, respectively, thereby increasing the gap between the liquid-containing parts of the extensible wall. Once the inflatable container has been sufficiently inflated, eg spherical in shape, the movement of the squeezing device can be stopped.

In various embodiments, a portion of the compressible pouch of the two-piece design adjacent to the squeezing device is left redundant and can be cut off, for example, with scissors. In various embodiments, the squeeze device may include an integral cutter to facilitate removal of the empty compressible pouch portion from the two-piece structure once the inflatable container has been sufficiently inflated.

In some embodiments of the present invention that use a sliding lid to squeeze liquid from a squeezable disposable pouch and force it into a portion of the inflatable container, the electrically driven emptying mechanism includes an electric motor coupled to the two-part structure to initiate a corresponding movement between the two-part structure and a mechanical compression member configured with the ability to displace liquid from a compressible bag into a device for feeding a child. In various embodiments of the present invention, the compression element is detachably coupled to the two-piece structure and can be removed from the device to maintain the seal of the infant feeding container after separation from the compression pouch.

With reference to embodiments of the device according to the said second broad aspect, the electric emptying device comprises: a mounting device for stabilizing the device in a vertical position on an outer surface, a hanging device connected to the mounting device and configured to accommodate and hold a two-piece structure in a vertical position, the two-piece the structure comprises: (i) a squeezable pouch for filling with liquid contents to subsequently form said feeding container, and (ii) an inflatable container representing said device for feeding a child, said holding being carried out with a squeezable pouch on top and an inflatable container on the bottom, the device further contains an electrically driven emptying mechanism for squeezing the compressible bag, thereby ensuring the supply of its liquid contents into the inflatable container.

In various embodiments of the present invention, the hanging device includes a plurality of (preferably three to four) spaced pins projecting upwardly at or near the top of the device. A squeezable pouch for use in such embodiments will comprise a suitable plurality of spaced openings corresponding to the pins and allowing the pouch to be suspended from the pins from the top of the pouch open to receive powdered and liquid formula ingredients for an infant.

In various preferred embodiments of the present invention, the mounting device includes in its middle portion either a clamping device configured to grip the two-part structure at the junction between the squeezable disposable pouch and the infant feeding device, or a limiting device to prevent upward movement of the inflatable container when squeezing is performed. In various embodiments of the present invention, the restraint device comprises a horizontally disposed U-shaped or C-shaped member having a sufficient internal dimension to accommodate a cylindrical junction area between the compressible pouch and the infant feeding device, yet narrow enough to allow the feeding device to no child passed through it.

As mentioned with respect to this first broad aspect, in various embodiments of the present invention, the inflatable container includes a connection portion removably coupled to a corresponding connection portion with which the compressible pouch is provided. Once the connecting portions are joined together, the compressible pouch and inflatable container are mechanically secured against accidental separation (eg, by providing the connector with a mechanical device, such as the type that requires manipulation involving pressing and rotating to separate). Thus, a certain upward pulling force acting on the compressible package will not cause the connecting parts to separate.

In various embodiments of the present invention, the compressible container is made from the same portion of material as the inflatable container and is a stretched inflatable container until the inflatable container is separated from the compressible pouch by a fluid sealing means, whereby it is released from the liquid connection with the compressible package. In such embodiments, the mounting structure includes a clamping device configured to grip the inflatable container to prevent upward movement when it is subject to a pulling force when squeezed by the pouch portion.

The inflatable container has a tensile outer wall configured to expand when liquid under pressure is introduced into it from a compressible bag.

Said disconnection of the liquid connection between the compressible bag and the inflatable container occurs after the inflatable container has been filled by introducing liquid squeezed out of the compressible bag.

In various embodiments, the liquid sealing apparatus comprises a pressing member configured to seal the inflatable container by applying pressure to the outer sides of the extensible wall, thereby holding the opposing inner surfaces thereof together, leaving no space for liquid between the opposing inner surfaces of the extensible wall in its regions , compressed by a squeezing device.

In some embodiments, the outer squeeze device is moved adjacent to the tensile wall, pressing against each other on its opposite sides to close any gaps between them so that liquid contained between the opposing internal surfaces of the tensile wall is pushed out of the closed gaps.

In some embodiments, the squeezing device is configured to be displaceable along the extensible wall from a distal end of the compressible pouch portion of the two-piece design more distal from the compressible container portion to a proximal end of the two-piece compressible pouch portion proximal to the inflatable container portion.

In some embodiments, the squeezing device is configured to hold a distal end of a portion of the compressible pouch of the two-piece design more distant from the portion of the inflatable container, thereby allowing the compressible pouch to be wound around the squeezing device from its distal end to its proximal end proximal to the portion of the inflatable container.

In the context of the present invention, the term "moving" when referring to a squeezing device refers to moving the squeezing device towards the inflatable container, either by displacement or by rotation, as provided by the type of squeezing device of interest in this embodiment.

By moving the squeezing device in the direction from the compressible pouch portion of the bicomponent structure to the inflatable container portion of the bicomponent structure, the liquid contained in the compressible pouch is pushed out of the closed gaps toward the inflatable container and the still spaced wall portions of the compressible pouch, respectively, thereby increasing the gap between the liquid-containing parts of the tensile wall. Once the inflatable container has been sufficiently inflated, eg spherical in shape, the movement of the clamp can be stopped.

In various embodiments, the portion of the compressible pouch of the two-piece design adjacent to the clamp is left redundant and can be cut off, for example, with scissors. In various embodiments, the clamp includes an integral cutter to facilitate removal of the empty compressible pouch portion from the two-piece structure once the inflatable container has been sufficiently inflated.

In embodiments of the present invention that use a movable lid to squeeze liquid from a squeezable disposable pouch and force it into a portion of the inflatable container, the electrically driven emptying mechanism includes an electric motor coupled to the two-part structure to initiate a corresponding movement between the two-part structure and a mechanical compression member configured with the ability to displace liquid from a compressible bag into a device for feeding a child. In various embodiments of the present invention, the compression element is detachably coupled to the two-piece structure and can be removed from the device to maintain the seal of the infant feeding container after separation from the compression pouch.

In a third broad aspect, the present invention relates to an infant formula cartridge comprising: (i) a frame (the frame is removably connected to an external corresponding holder that constitutes an element of the emptying device according to the first aspect of the present invention); (ii) an elastic reservoir connected to the frame; (iii) a liquid discharge opening in fluid communication with the elastic reservoir and removably connected to a corresponding liquid receiving port of the inflatable infant feeding container, and connecting means corresponding to a common connecting means configured to hold the cartridge with the inflatable feeding container baby feeding device connected to the liquid discharge hole of the cartridge.

In a fourth broad aspect, the present invention relates to a method of final preparing infant formula and introducing it into a disposable inflatable infant feeding container, comprising: (i) providing a cartridge containing an elastic reservoir partially filled with infant formula in a powdered state; (ii) introducing the required amount of water into the elastic reservoir and shaking the cartridge to dissolve the powder and mix it with water; (iii) providing a liquid-tight connection between the liquid receiving port of the inflatable infant feeding container and the formula discharge opening of the cartridge; (iv) providing a pressure difference between the pressure inside the elastic reservoir and the pressure inside the inflatable container, whereby the prepared mixture from the elastic reservoir is discharged into the inflatable container; and (v) separating the inflatable container from the cartridge.

A fifth broad aspect of the present invention provides embodiments of a liquid receiving nozzle for inflatable infant feeding containers for filling by an emptying device disclosed as part of said first and second broad aspects, the liquid receiving nozzle including a clamping device for securing the open end of the expandable inflatable container. container for feeding a child adjacent to the main part of the pipe for receiving liquid, at least one hole in the wall of the specified main part and a diaphragm located in front of at least one hole, whereby the pressure of the liquid from inside the expandable container presses the diaphragm against the wall, thereby sealing the hole with using a diaphragm, whereby fluid pressure from the outside of the expandable container forces the diaphragm away from the wall, thereby creating a temporary gap between the wall and the diaphragm through which liquid from the outside can flow into the expandable container.

Accordingly, the embodiment of the present invention is to be considered in all respects as illustrative and not limiting, the scope of the present invention being set forth in the appended claims rather than in the following description, and all modifications relating to the meaning and degree of equivalence of the claims are therefore intended to be inventions must be included in it.

In fig. 1 and 2 show in an open state (FIG. 1) and a closed state (FIG. 2) an electric emptying device 100 for automatically transferring liquid from a supply container to a baby feeding device according to a preferred embodiment of the present invention.

The electric emptying device comprises a housing 101b and 101c, a door space (103b; 103c; 104b; 104c) within the housing configured to accommodate and hold a two-part structure (300, shown in FIG. 3) comprising: (i) a compressible package 301, pre-filled with liquid contents and representing said supply container; and (ii) an inflatable container 311 representing said baby feeding device; and an electrically driven emptying mechanism (e.g., the electrical mechanism 130 shown in FIG. 1A, in cooperation with the mechanical means illustrated in FIG. 1) for squeezing the compressible pouch, thereby discharging its liquid contents into the inflatable container.

In the illustrated embodiment, the electric emptying device 100 includes a main part 101b having a base part 102 for supporting the device on a horizontal surface, such as a table. The door 101c is hinged to the main body 101b by a pair of hinges 115 connected to the door 101c near its top, each of which is hinged to the main body 101b within a corresponding hinge capsule 113 formed near the top of the main body 101b. The hinges are sized and configured such that when door 101c is substantially fully opened, it remains in its open position (e.g., by gravitational force acting on its mass) without the need for the user to hold it. The user can then hang the two-piece structure shown in FIG. 3, onto the horizontal pins 117, and then close the door.

Although the compressible pouch 301 can hold a limited predetermined volume, the door space is spatially sized to accommodate twice that volume: at its top 103b and 103c there is a compressible pouch 301 filled with a maximum predetermined volume of liquid contents, and at its bottom - an inflatable container 311 filled with the specified specified volume. Thus, the total volume of the door space is at least twice the volume transferred from the compressible disposable pouch 301 to the inflatable container 311 .

In preferred embodiments of the present invention, the door space has a hanging arrangement to hold the two-piece structure in an upright position, with the compressible bag at the top and the inflatable container at the bottom. In various embodiments of the present invention, such as those illustrated herein, the hanging device includes two spaced apart horizontally oriented pins 117 projecting into the door space 103b near its top. A compressible pouch 301 for use in such embodiments will comprise a pair of spaced apertures 304 corresponding to pins 117 and allowing the pouch to be suspended from the pins. Thus, the package can be hung on the pins by securing it inside the door space, the pins 117 being respectively inserted through the holes 304 .

In various preferred embodiments of the present invention, the door space includes in its middle portion a clamping device configured to grip the two-part structure 300 at the junction between the compressible disposable pouch 301 and the baby feeding device 311 . In various preferred embodiments of the present invention, the clamping device includes a first semicircular element 108b protruding from the rear wall 101b of the door space and a second semicircular element 108c protruding from the door 101c of the door space, the two semicircular elements 108a and 108c being arranged so that when the two-piece structure 300 having a cylindrical connection area 305 between the compressible disposable pouch 301 and the baby feeding device 311 is suspended by a holder 117 located near the top of the door space, said cylindrical connection area 305 was located adjacent to the first semicircular element 108b and, after closing the door 101c is caught between and held firmly between the first and second semi-circular members 108b and 108c, which together form a ring-shaped clamp fit tightly around the cylindrical joint region 305 of the two-piece structure 300.

The electric emptying device includes an electric mechanism, such as mechanism 130 shown in FIG. 1A. In the illustrated embodiment, the mechanism 130 is built inside a compartment formed in the main part 101b behind the wall part 114. Button 120 is located in wall portion 114 and is connected via line 121 to device controller 133. When the door 101c is closed, the button 120 contacts an actuator 120c provided near the top of the door 101c and is controlled by the user. Once pressed by the user, and provided that the door sensor 140 (may be located, for example, inside the hinge capsule 113) transmits a signal to the controller 133 that the door 101c is closed, the controller 133 connects the battery B to power the electric blower pump 131. Then the forced air flows from the pump into the upper space 103b and 103c through the air tube 131t, whereby the air pressure in the upper space 103b, 103c of the electric emptying device increases. The space 103b and 103c is sealed from the external air environment by means of the top, bottom and side walls forming part of the main body 101b and the door 101c, as well as by mirror spacers 105b and 105c (for example, made of rubber, silicone or the like), which are aligned when door 101c is closed. Door 101c and body 101b preferably include means (either mechanical or magnetic) for keeping the door tightly closed when pressed. Magnetic elements may be incorporated within opposing edges of the body and door to mutually interact magnetically to keep the door tightly closed. Spacers 105b and 105c also fit around the cylindrical neck 305 of the compressible package 301. The horizontal wall 106b and 106c divides the door space into an upper space 105b, 105c and a lower space 104b, 104c. When the door 101c is closed, the cylindrical neck of the compressible pouch 305 is held between the first and second semicircular members 108b and 108c, which are formed, respectively, by semicircular recesses in the horizontal wall portions 106b and 106c.

The base portion 102 of the main body 101b is provided with an ergonomic recess 111 to facilitate access to an ergonomic handle 112 provided near the bottom of the door 101c by which the door 101c can be opened and lifted.

Preferably, door 101c includes a transparent front panel 110 through which the user can monitor the operation of the device and stop operation once a sufficient amount of liquid has been transferred into the inflatable container. This may be indicated, for example, by the satisfactory volume of the inflatable container.

In various embodiments of the present invention, the electrical function of the device may be disabled upon a second press of the activation button 120c. In another embodiment of the present invention, the electrical function of the device may be disabled by opening door 101c. The opening signal is transmitted to the controller via door sensor 140 .

In fig. 3 illustrates a two-piece structure 300 comprising a squeezable pouch structure 301 and an inflatable infant feeding container 311 configured to automatically transfer liquid from the squeezable pouch structure 302 (squeezable pouch structure 301) into the container 311 through the embodiment of the device shown in FIG. 1. The compressible pouch structure 301 may be supplied to the user in the form of a cartridge containing a rigid or semi-rigid frame 303 and an elastic pouch 302, which may be made of nylon, aluminum foil or the like. The elastic pouch 302 (which is the reservoir for the baby's formula) is connected to a cylindrical rigid or semi-rigid neck 305. Within the cylindrical neck 305 is a normally closed valve that opens when the neck is connected (for example, through a common thread or through any suitable connector, with which the bag and the baby feeding device are supplied together) with a liquid inlet (not shown in this case, for an example, see the details of the liquid inlet, for example, in the document WO2006129302 in Fig. 2) of the inflatable baby feeding device 311 , and provides a fluid connection between the bag 302 and the inflatable balloon-like member 312 of the baby feeding device 311 .

The frame 303 of the compressible bag 301 includes a pair of holes 304 aligned with a pair of horizontal pins 117 of the electrical emptying device, whereby the two-piece structure 300 can be positioned within the door space 103b, 104b, 103c, 104c by suspending it from the pins 117.

In the illustrated embodiment, the inflatable element 312 of the baby feeding device is protected by semi-rigid plastic frame members 314 and 315, wherein the plastic frame member 314 connects to and provides mechanical support for the baby feeding tip 313 of the baby feeding device. Plastic frame member 315 provides mechanical support for a fluid inlet (not shown in the drawing, within semi-rigid neck 305) to which the compressible package 301 is releasably connected.

In fig. 4 shows, from a conventional perspective, the two-piece structure 300 shown in FIG. 3, located inside the device shown in FIG. 1, at the end of the automatic moving process. Door 101c has a clear front panel that provides an unobstructed view of the unit when closed. The two-piece structure 300 is suspended within the device by horizontal pins 117. The pins 317 respectively pass through holes 304 formed in the frame 303 of the compressible package 301, the cylindrical neck 305 of the two-piece structure being tightly held by semicircular recesses 108b and 108c formed in the horizontal wall portions 106b and 106c. The inflatable baby feeding device 111 is suspended by a cylindrical neck 305 to which its liquid inlet is detachably attached. The inflatable baby feeding device 311 is located inside the lower compartment 104b and 104c of the electric emptying device, isolated from the air contained in the upper compartment 103b and 103c.

The figure shows the elastic reservoir 302 after the automatic liquid movement has completed, when it is already empty of liquid (for comparison, see the view in which it is filled with liquid shown in Fig. 3). The baby feeding device 311 is shown with the balloon-like member 312 in its inflated state, filled with liquid which has been forced into it from the bag 302 through the cylindrical neck 305 and through the liquid inlet, by means of the higher air pressure created in the upper compartment 103b and 103c in during the fluid movement process. After the liquid transfer process is completed, the user can lift the door 101c to open it by pulling the handle 112, then remove the two-piece structure 300 from the horizontal pins 117 and finally separate the baby feeding device 311 from the cylindrical neck 305 of the squeezable bag 301 and unload it for feeding a baby.

In fig. 5 shows an electrical emptying device 200 for automatically transferring liquid from a supply container 401 to a baby feeding device 311 in accordance with a preferred embodiment of the second broad aspect of the present invention. A two-piece structure 400 comprising a compressible pouch 402 and an inflatable infant feeding container 312 is shown in position on the device 200. The device includes a base portion 406 representing a mounting fixture and a top portion 442 having an opening 420 having four upwardly facing pins 403 , located at a distance around the hole and representing a hanging device. The hanging fixture is coupled to and mechanically supported by the mounting fixture 406 (e.g., by vertical wall members 404 and 405) and is configured to house and hold the two-piece structure 400 in a vertical position, the two-piece structure 400 comprising: (i) a compressible pouch 402 for filling with liquid contents and when filled, representing said feeding container, and (ii) an inflatable container 312 representing (using tip 313 and frame members 314 and 315) said device for feeding a child, said holding being accomplished with a squeezable pouch 402 on top and an inflatable container 312 at the bottom, the device further comprising a motorized emptying mechanism for squeezing the squeezable pouch 402 thereby discharging its liquid contents into the inflatable container.

The compressible pouch 402 comprises in its upper portion 401t openings 403h, which in the illustrated embodiment are provided in the main portion of the pouch near its top portion 401t (and which in other embodiments may be provided in specially provided strips extending from the compressible pouch), said the holes are configured to accept pins, respectively, to suspend the pouch 402 from the pins 403 and facilitate the introduction of water and powdered infant formula into the pouch through its open top portion 451. After the user has completed formula preparation (in some embodiments, as part of the device mechanism a mixing device is provided, so in such embodiments, the user only needs to pour the ingredients into the bag 402, and the mixing is carried out automatically), the user can turn on the electrically driven emptying mechanism (the activation switch, electrical elements and circuits can be designed by experts in the field of electrical appliances based on general knowledge and therefore not shown).

The electrically driven emptying mechanism for squeezing the compressible package 402 contains a pair of slats (rods) 462 and 463, each of which is hinged at its proximal end with a common hinge 416 of the specified pair of jointly attached hinged slats, representing a pincer-like mechanism. The hinge is formed in a recess in the rotatable main body 412 and is initially oriented vertically. The rotatable main body is connected to the gear 414 such that when the gear rotates, the rotatable main body will also rotate. The gear 414 and the rotatable main portion 412 are rotatably attached to the cylindrical portion 417, the cylindrical portion being partially truncated such that a portion of the gear 417 is open and therefore mating with the vertically oriented gear rod 432. As can be understood, thereafter As the truncated cylinder portion 417 moves downward, the exposed portion of the gear 417 engages the gear rod 432 and rotates counterclockwise (to an observer facing the device from the front) in response to the linear downward movement of the cylindrical portion 417.

After introducing the liquid mixture into the bag 402, the pincer rods 462 and 463 may close to close the bag 402 above the level of the liquid contents. The pincer rods can be brought together either manually before turning on the device, or automatically. To automatically bring the pliers together, the vertical wall 405 contains a slot 409, the slot being wide at its top portion 407, gradually tapering at its middle portion 408, and having a fixed width along its entire length at its bottom portion 409. At the start of cooking, the truncated cylindrical portion 417 is located near the top of the device, and the pincer-shaped rods 462 and 463 therefore extend through the top of the slot 407. The top of the slot 407 is wide enough to allow the pincers to spread apart, which in turn allows the bag 402 to be suspended by the pins 403, fully deployed between the pincers 462 and 463. Once the squeezing process is activated, the truncated cylindrical portion 417 moves downwards into depending on the rotation of the threaded drive rod 419, bringing the pincer rods into the tapered slot area 408, thereby gradually compressing the pincer rods together, and, in turn, squeezing and closing the bag 402 from the baby formula located above in the container. Further downward movement of the truncated cylinder 417 will engage the gear wheel in mesh with the gear rod 432, thereby rotating the rotatable member 412 and the pincer rods. The rotation of the closed tick -shaped rods causes wound up the compressed packet 402 on the tick -shaped rods 462 and 463, tearing the bag with pin 403. When rotating (wrapping) the packet 402 around the closed rods, the upward movement 311 is prevented by feeding 410 (in the spontaneous variant of the implementation of the implementation of horizontally, horizontally oriented C-shaped stop) that connects to the vertical wall 405 near the bottom of the slot 409.

Thus, rotating and winding the bag will seal the bag 402 from leaking liquid mixture through the top of the bag and will compress its contents, forcing them into the inflatable container.

The truncated cylindrical element 417 is attached to a threaded cylindrical body 411, which is mated to a threaded drive rod 419. Clockwise or counterclockwise rotation of the threaded drive rod 419 (depending on the current operating mode of the device) will be converted into a corresponding linear movement of the cylindrical body. 411 downward during a squeezing session and upward after squeezing to return the device to its original state using pincer-shaped bars extending from the wide top portion 407 of the slot 409 .

The cylindrical body 411 has a vertically extending lateral groove 411g (e.g., having a T-shaped cross-sectional contour) corresponding to a vertical guide 431 protruding from the vertical rod 430. The guide and groove configuration allows for smoother linear movement of the cylindrical body 411 and the truncated body. cylindrical portion 417, whereby the cylindrical portion 417 is prevented from rotating laterally due to rotation of the threaded drive rod 419.

The toothed rod 432 connects to the vertical rod 430 at a predetermined location and has a predetermined length configured to cause the required number of revolutions of the gear 414 to rotate the bag 402 and squeeze all of its contents into the inflatable container 312.

The threaded drive rod 419 is connected to an electric motor (not shown) controlled by associated electronic circuits. In some embodiments of the present invention, the electronic circuits include sensing means for automatically stopping the engine at the desired highest and lowest positions of the truncated cylinder 417 and for reversing the direction of rotation of the engine when the device returns to its original position upon a user command subsequent to completion of filling in squeezing session time.

The electric motor may be located near the bottom of the device or, as a design feature, at any desired location between walls 404 and 405 .

In various embodiments of the present invention, the electric emptying device further includes a stirring element configured to manipulate the liquid contents of the compressible pouch by repeatedly deforming the pouch 402 on the outside thereof, thereby agitating its contents.

The stirring element may be, for example, an eccentric wheel coupled through suitable gears to a vertical toothed rod (similar to rod 432 or representing an upwardly projecting portion extending from the top of the illustrated rod 432) so that before the pincer rods 462 and 463 will begin squeezing and winding the bag 402 (i.e., before closing they pass into the slot 409 while moving down and), the eccentric wheel pushes the wall of the bag from the outside, causing the liquid inside the bag to agitate and ensure more even mixing with the instant formula for feeding the baby. The eccentric wheel may be located directly above the pincer bars 462 and 463 and may be configured to stop their downward movement and resulting rotation immediately when the pincer bars close and close the package 402.

In fig. 5A through 5E show several views of a manually operated emptying device 250 for moving liquid from a supply container 401 to a baby feeding device 311 in accordance with a preferred embodiment of the second broad aspect of the present invention. The two-piece structure 400 containing the compressible pouch 402 and the inflatable feeding container 312 can be hung from the pins 499 in a manner similar to hanging the two-piece structure 400 on the device shown in FIG. 5. The squeezable bag 402 includes on its top portion 401t holes (or specially provided strips with holes) configured to insert pins, respectively, for suspending the bag 402 from the pins 499, thereby facilitating the introduction of water and powdered infant formula into the bag. through its open part 451.

The manual device 250 includes surrounding walls 498a-498d that create a space 496 for hanging the two-piece structure 400. The surrounding walls may (but not necessarily) end with a base wall 497 to enclose the space 496 from below. The opposite walls 498a and 498b of the four walls contain through grooves 495a and 495b, respectively, near the top of the walls. The through-grooves 495a and 495b are used as guides for a pair of clamping rods 494a and 494b, each of which intersects the opposing walls 498a and 498b through the through-grooves so that they can be moved laterally from the corresponding end of the through-grooves to the middle part thereof. In the middle portion of each of the through grooves there is a rotatable coupling wheel 993 clamped so that it can only rotate while remaining stationary laterally along the groove. The coupling wheel 490 includes a common releasable coupling means with each of the clamping rods. The releasable connecting means are configured to engage between the wheel and the clamping bars after the clamping bars are closed by user action. When both clamping rods 494a and 494b are connected to the wheels 490, respectively, the rods rotate with the rotation of the wheels 490 about a common rotation axis 490a of the wheels 490.

One example of a common coupling means between the wheels 490 and the clamp bars 494a and 494b is a plurality of (at least two) recesses 490r formed in the wheels having a contour to fit snugly against the tubular portion 494t of the clamp bar, keeping it from inadvertently separating from the wheel. .

After suspending the two-piece structure 400 with the vertical pins 499, and prior to filling and final mixing, the closure of the clamp bars 494a and 494b will clamp the top of the compressible feed package 402 between the clamp bars in an area along the common axis of rotation 490a between the wheels 490. In various In embodiments of the present invention, each of the clamping rods may have a star-shaped cross-section in a transverse direction to its longitudinal axis. The clamping rods 494a and 494b can then be rotated by the user, thereby winding the compressible package 402 and reducing its volume. To achieve rotation of the clamping bars, the user can use the flat ends of the clamping bars 494e as handles to facilitate rotation while applying a compressive force to the liquid contained in the compressible pouch. Lever rods 459 may be provided perpendicular to the clamp bars to maintain the flat ends 494e in an upright position when disengaged from the wheels 490 and to facilitate rotation of the clamp assembly (i.e., wheels 490, clamp bars 494a, 494b, and the compressible package 402 clamped by them) by amplifying the manually applied force on the clamping bars 494a, 494b to rotate the compressible package and wrap it around the clamping bars. The upward movement of the baby feeding device 311 due to the rotation operation is stopped by a stop (not shown in FIG. 5B), such as the horizontal C-shaped stop 410 in FIG. 5A. The stop may be coupled to a surface of a vertical surrounding wall 498a (or any of 498b through 498d) facing a space 496 near the mid-height portion of the wall. Thus, through the rotation operation, the compressible bag is stretched in the vertical direction, which in turn causes its internal volume to decrease, thereby displacing the liquid contents therein from the bag into the container 311. After clamping, a predetermined amount of air will inevitably be trapped between the clamped end of the compressible package and the liquid contained in it. Due to the entrapped air, rotation of the clamping rods will cause the compressible pouch to gradually decrease in volume and increase the pressure of the entrained air, whereby the entrained air will exert pressure on the liquid, thereby allowing the user to squeeze out any last remaining liquid from the compressible pouch into the container. The walls of the device may be made of transparent material and contain a transparent area that allows the squeezable pouch to be monitored so that the user can see the squeezable pouch being emptied and complete squeezing in time, i.e., before any trapped air enters the baby's feeding container .

In fig. 5H shows the top of an electric emptying device 850 for moving liquid from a supply container 401 (reference numerals mentioned in the description of this figure, which are not included in the drawing, refer to the items marked with those reference numerals in FIG. 5 or other figures, and may be included in the embodiment and processed by the user in the same manner as in the embodiments in which they appear and are described) in the baby feeding device 311 according to another preferred embodiment of the second broad aspect of the present invention. The two-piece structure 400 containing the compressible pouch 402 and the inflatable infant feeding container 312 can be suspended from the pins 899 in a similar manner to the two-piece structure 400 suspended from the pins 499 of the device shown in FIG. 5A, or at pins 403 of the device shown in FIG. 5. In various embodiments of the present invention, gripping means other than pins may be used to suspend the two-piece structure. Such means may include hooks, spring-loaded latches, outwardly curved edges, or the like. The compressible package 402 contains in its upper part 402t holes 403h (or specially provided strips with holes, and said strips are attached to the compressible package in such a way that the holes in the strip are located near the upper end of the compressible package), configured to insert pins, respectively, through holes 403h for hanging the bag 402 from pins 899, thereby facilitating the introduction of water and powdered infant formula into the bag through its open top 451.

Electrical device 850 includes surrounding walls 898 (for example, such as walls 498a-498d of the embodiment of FIG. 5) that create a space 896 within which the two-piece structure 400 can be suspended. The walls 898 may (but are not necessarily) terminated in a base wall (like base wall 497 in Fig. 5) to close the space 896 from below. In the vicinity of two parts of opposite walls of the surrounding wall 898 (to form the surrounding wall, a different number of walls can be implemented as a design object and without departing from the scope of the present invention, for example, one wall in a round or oval configuration, six walls in a hexagonal configuration, etc. .) two threaded drive rods 819 are located, which are respectively coupled to a compression mechanism for squeezing the compressible pouch 402 to transfer its contents into the inflatable feeding device 311 . The squeeze mechanism in the illustrated embodiment includes a pair of plates 862 and 863 that are configured to close the package 402 and to wind it (instead of the similar function of the pliers mechanism of the embodiment shown in FIG. 5 or the function of the clamp bars of the embodiment shown in Fig. 5A). The plates 862 and 863 include holes 863h at their opposite ends 863e, whereby they are secured together with their ends 863e attached to the mirror rotatable members 812 by means of pins 816. Rotation of the rotatable members 812 occurs as the rotatable members move up and down whenever the gear wheels 812 engage the toothed portion of the gear rods 832, and the drive rods 819 rotate and displace the truncated cylindrical parts 817 down (in which case the plates will rotate in a first direction about their common axis of rotation 877) or down (in which case the plates will rotate in a second direction about their common axis of rotation 877 opposite to said first direction of rotation). For up and down movement as well as for rotation, means similar to that used in the embodiment of FIG. 5, such as T-groove and guide. The clutch mechanism is configured to maintain both rotating members 812 at the same height from the bottom of the device as they move up and down. For example, both rotatable elements may be coupled to a common electric motor through the same or identical coupling mechanisms, whereby the motor acts to move the two rotatable elements 812 along the gear bars simultaneously and in the same manner in a mirror-image manner. The mechanism is further configured to maintain simultaneous rotation of both rotating elements around a common axis of rotation 877, in mirror (shared) rotation directions.

However, the connection between the rotatable members 812 and the gears 814 is different from the connection of the rotatable main body 412 shown in FIG. 5, with a toothed bar in which the rotatable element 812 also rotates laterally toward its mirror counterpart by a predetermined distance when the rotatable elements are at or near their highest position relative to the guides. A mechanism is proposed for lateral movement of each of the rotatable elements 812, and which is configured such that the lateral movement occurs simultaneously for both rotatable elements 812 in opposite directions along a common axis of rotation 877. In various embodiments of the present invention, the lateral movement mechanism may include cables that pull the rotating elements laterally as the cables are wound around a rotating shaft, such as a common electric motor shaft. The lateral movement mechanism may be coupled to the same electric motor that provides vertical and rotational movement of the rotating elements. Since the lateral movement of both rotating elements occurs in opposite directions (due to the mirror configuration), both rotating elements can move closer to or further away from each other when lateral movement occurs. In various embodiments of the present invention, the lateral movement of each of the rotatable members 812 is directed against the biasing force. In various embodiments, the biasing force may be generated by compressible spring(s), magnetic attraction or repulsion, etc. In the illustrated embodiment, plates 862 and 863 are resilient and tend to maintain a straight shape. Thus, when the opposite ends 863e of the plates 862 and 863 are pressed closer, they are temporarily deformed and each takes on a curved shape, as illustrated in FIG. 5G. The curved shape allows the bag 402 to be suspended between the plates with its top wide open. The displacement force BF caused by the deformation of the plates acts bilaterally, as indicated by the arrow with the reference position BF, and tends to return the plates to a straight shape. Returning plates 862 and 863 to a straight shape will close the stack 402 between them, pinching its open end between the plates.

In the illustrated embodiment, lateral movement of the rotatable members 812 toward each other is provided by a pair of curved guides 832c that extend in a diagonal direction from the gear bars 832. In the illustrated embodiment, the rotatable members 812 are connected telescopically to the gears 814 via a bar 813 protruding from the rear portion 812r each rotatable member 812, respectively, into a recess 815r that extends laterally into a projecting portion 815 of the corresponding gear 814. The guide 832c is configured to guide the rear portion 812r of the rotatable member 812 away from the gear when the truncated cylindrical portion 817 moves ( as the threaded drive rod 819) rotates upward into an area on top of the top of the toothed area of the gear rod 832. In this area, the gear does not rotate (due to being disengaged from the teeth of the gear rods), with the rear portion 812r of each rotating elements is pushed by the curved guide 832c away from the gear and against the biasing force BF, pushing the ends 863e of the plates 862 and 863 towards the center of the space 896, whereby the plates eventually assume their curved position, as shown in FIG. 5G when they reach their highest location at the top of the bottom of the device. In fig. 5F shows the position of the rotatable member 812 relative to the curved guide 832c and the gear 814 when the rotatable member 812 is in its highest position. In this position, the rotating element 812 is lateral to the gear 814 compared to its position in FIG. 5H, and rod 813 is partially withdrawn from recess 815r. The rod 813 and the recess 815r are configured to have no rotational symmetry about the axis 877 (for example, they may have a rectangular cross-section perpendicular to the axis of rotation 877. Therefore, the rotation of the gear when it engages the teeth of the gear rod 819 is transmitted to the rotatable element 812.

The gear region and telescoping attachment 813 and 815r are mutually configured so that the plates 862 and 863 are oriented vertically and the pins 816 are oriented horizontally whenever the gears 814 are disengaged from the gear bars 832 during vertical movement of the cylindrical main parts. In fig. 5H illustrates the apparatus immediately after the stack 402 is clamped by the plates 862 and 863, which are shown just before the gears 814 rotate to engage the serrated region of the gear bars as the truncated cylindrical member 814 moves downward. The rotation of the gears will cause the pouch 402 to be torn off the pins 899, coiled around the plates 862, 863, thereby compressing to empty and transfer the liquid contents 402f to the inflatable feeding device 311.

In fig. 5I shows the upper portion of an electric emptying device 550 for transferring liquid from a supply container 401 (reference numerals mentioned in the description of this figure, which are not included in the drawing, refer to the items marked with those reference numerals in FIG. 5 or other figures, and may be included in the embodiment and processed by the user in the same manner as in the embodiments in which they appear and are described) in the baby feeding device 311 according to another preferred embodiment of the second broad aspect of the present invention. The device 550 differs from the device 850 primarily in that the axis 577 of rotation of the plates 862 and 863 is stationary in the vertical direction in the device 550. Thus, the device 550 does not contain mechanisms involved in the vertical movement of the plates 862 and 863, such as drive rods 819, racks 832, their diagonal parts 832c, gears 814 and a truncated cylindrical part 817.

Instead, rotation of the rotatable members 812, and thus the plates 862 and 863, may be accomplished, for example, by an electric motor 522. The horizontal movement of the rotatable members 812 at opposite ends of the plates to and from each other may be provided either manually by the user, for example, by means of a hand lever (not shown), or by an electrical drive, such as a helical coupling 512h and 514 located between the motor rotation shaft 522s and a common end of the plates (connected to a rotating element 812) located at at least one common end of the plates. The helical coupling 512 ensures that the motor rotation shaft 522s rotates at a predetermined number of revolutions (according to the number of helical lines 512h), without rotating the rotating elements 812 and, therefore, without rotating the plates.

At the beginning of the emptying session, the rotation of the shafts 522s causes the screw couplings 512 to push apart the rotating elements 812 (and therefore the opposite common ends of the plates 862 and 863), thereby closing the plates, straightening them and closing the upper part of the compressible package 402. The rotation of the plates is ensured by further rotation shafts 522s after the plates have already straightened, whereby the package 402 is closed. The rotation of the plates occurs when the rotation of the screw couplings 512 relative to the screw pushers 513 stops after the plates 862 and 863 have straightened, thus preventing the distance between the rotated elements 812 from further increasing.

At this stage of operation, the package begins to wind around the rotating plates, whereby its internal volume 402f gradually decreases. Another result of winding the bag 402 while rotating the plates is that the baby feeding device 311 is gradually raised. This is because the 550 does not have a limiter like the 410 limiter.

Adjacent to and below the plates 862 and 863 is a restriction member 503 for blocking the baby feeding device 311 itself (as well as the liquid-filled portions of the compressible pouch 402f) from contacting the rotating plates, thereby preventing them from undesirably wrapping around the plates. The limiting element 503 may be mounted on a spring-loaded axis 504 that supports the passage of the limiting element in the same horizontal plane substantially parallel to the axis 577 while allowing it to rotate between the first and second extreme positions.

In the initial state, starting before hanging the two-piece structure on pins 899, the plates 862 and 862 are arc-shaped (as shown in Fig. 5G), the rotating elements 812 are closest to each other, and the limiting element 503 is supported by a spring-loaded axle 504 with an end 503e limiting element 503 away from the drawing plane such that the imaginary vertical plane in which the ends 503e and 503h of the limiting element are typically located forms an angle of at least 45 degrees with the vertical plane in which the axis of rotation 577 is located, representing said first extreme the position of the limiting element and facilitating the installation of the two-part structure through the hole made between the arc-like plates 862 and 863. After the preparation of the liquid mixture 402f inside the compressible package 402 is completed, the transfer of the prepared mixture into the baby feeding container can begin by activating the motors 522. Rotation of the shafts 522s of the engine causes rotation of the screw couplings 512, which move the rotating elements 812 away from each other by means of the screw couplings 512h and 514, thereby straightening the plates 862 and 863 and closing the compressible package 402. One of the rotating elements 812 may include a disk-shaped flange 512f, so that upon lateral movement of the corresponding rotating element, the flange 512f pushes the lever 503h of the limiting element 503, thereby rotating the limiting element until it reaches its second extreme position, the vertical plane in which the limiting element is located being parallel or almost parallel to the axis 577 rotation.

Leaf spring 502 may be coupled at its first end to a wall (e.g., surrounding wall 898) of the device such that its second end is in frictional engagement with rotatable member 812 to prevent the plates from rotating due to friction between the screw couplings 512 and the pushers 513 when the screws clutches 512h and 514 perform the specified specified number of revolutions.

Reverse rotation of the plates after completion of the fluid transfer process to release the used compressible pack 402 from the plates 862 and 863 and return the plates to their original position, prepared for a new fluid transfer session, can be accomplished by activating the motors 522 in the reverse direction. In some embodiments of the present invention, rotation of the motors 522 (and therefore the helical couplings 512) may be in a first direction against a biasing force, such as against the force of a coil spring (not shown in the figures) coupled at its first end to a fixed point of the device and at its second end with a point being rotated by the motor shaft 522s, whereby the reverse rotation of the plates 562 and 563 to their original position is automated by the spring force after the power supply to the motors 522 is turned off after completion of the liquid movement process.

In fig. 5J shows the top of an electric emptying device 580 for transferring liquid from a supply container 401 (reference numerals mentioned in the description of this figure, which are not included in the drawing, refer to the items marked with those reference numerals in FIG. 5 or other figures, and may be included in the embodiment and processed by the user in the same manner as in the embodiments in which they appear and are described) in the baby feeding device 311 according to another preferred embodiment of the second broad aspect of the present invention.

Apparatus 580 differs from Apparatus 550 primarily in that the plates 862 and 863 in Apparatus 580 are configured primarily for manual user control, both in their rotation function and in lateral movement of their ends (with Apparatus 550 adopting a configuration that can considered more suitable for operation with an electric motor). Rotation of the rotatable members 812 and thus the plates 862 and 863 may be manually performed by the user, for example, through a rotatable handle 534 or, for example, a removable ratchet handle 546, through which the user can operate the shaft arms 533 and 543, respectively. Each of these handles represents a different variation of the 580. The first variation of the 580 lacks the removable ratchet handle 546 and has handles 534 on both opposite side ends of the device in a mirrored configuration. The second variation of the device eliminates the removable ratchet handle 546 and its shaft lever 533, and the shaft levers 543 are present on both opposite side ends of the device in a mirror configuration, with the removable ratchet handle 546 secured between them, thereby allowing the levers to operate simultaneously. shaft on both side ends of the device. A ratchet mechanism 537 having a direction selector is an intermediate member among the shaft parts between the shaft end part 531 and the shaft part 531r so as to allow the user to select the direction of rotation allowed by the ratchet mechanism for each step of operation of the device. The removable ratcheting handle 546 extends freely through the lever 543 through a corresponding hole located near the free end of the lever, thereby allowing the user to move the shafts 531 laterally away from each other. The 547 discs prevent the 546 removable ratchet handle from falling out of the 543 arms.

Horizontal movement of the rotating members 812 at opposite ends of the plates toward and away from each other may be achieved by bringing in or retracting the shafts 531 on either side of the device through tubular openings 530 located at opposite ends of the surrounding wall 898 of the device. The lateral movement of both shafts in either direction is indicated by a double-headed arrow 599, depending on the stage of operation of the device. In the illustrated position, the shafts 531 are closest, hence the plates are in their arced state, as shown in FIG. 5G.

The tubular holes 530 have a non-circular cross-section in a vertical plane perpendicular to the drawing surface, such as a square cross-section, corresponding to the cross-section of the corresponding shaft in the shaft region 531s. A spring-loaded ball bearing 531b may be provided to support the shaft 531 in the illustrated position while filling the compressible pouch 402 and preparing the infant's formula. The plates 862 and 863 cannot rotate in the illustrated shaft position and the hole formed between them due to their arcuate shape is horizontally aligned (to receive a two-piece structure through the top hole of the device) due to the mutual alignment between the cross-section design of the tubular holes 530 and the cross-section shaft 531 in the area 531s of the shaft.

The outward-facing ends of each of the shafts 531 may have a circular cross-section of a larger diameter than the inner cross-section of the tubular opening, thus preventing the shafts from being brought closer together than illustrated.

Each of the shafts 531 further includes an area 531r located on the shaft at the inner end of the corresponding tubular hole 530. The shaft area 531r has a circular cross-section perpendicular to the drawing plane and has a diameter in accordance with the dimensions of the cross-section of the hole 530 so as to allow rotation of the shaft 531 about an axis 597 during the operation step where the region 531r is located inside the tubular opening 530. This operation step takes place after the preparation of the infant formula inside the compressible pouch is completed after the user pulls the shafts 531 outward on both side ends of the device 580.

The linear movement of the rotatable elements 812 influences the position of the limiting element 503 by causing it to rotate about an axis 504 in accordance with the lateral location of the disk-shaped flange 512f along the axis 597, as described above for the device 550, and by interacting with the arm end 503h of the limiting element 503.

In fig. 5K-5L show views of a manually operated emptying device 270 for moving liquid from a supply container 401 to a baby feeding device 311 in accordance with another preferred embodiment of the second broad aspect of the present invention. It should be noted that the illustrated embodiment is shown as having its main body made of transparent material (similar to the embodiments shown in FIGS. 5 and 5A), such that the rear facing portions of the main body and some supported movable members are visible through the front facing portions walls of the main part.

The two-piece structure 400 containing the compressible pouch 402 and the inflatable feeding container 312 can be hung from the pins 499 in a manner similar to hanging the two-piece structure 400 on the device shown in FIG. 5. The compressible bag 402 contains on its top part 401t holes (or specially provided strips having loops or holes at the free end of the strip) configured to insert pins, respectively, for suspending the bag 402 from the pins 499, thereby facilitating the introduction of water and powdered formula for feeding a baby into the bag through its open part 451.

The manually operated device 270 includes a main body 487 containing surrounding walls 488a-488d that create a space 486 between them for hanging a two-piece structure 400. The space 486 is accessible either through an opening 487o formed in the top wall 487t of the main body 487 or through access recesses 488r formed in one or two surrounding walls 488a or 488b. The surrounding walls may (but do not in the illustrated embodiment) end at their lower portion with a base wall to enclose the space 486 from below. Each two opposite walls 488c and 488d of the four contain five grooves. Two of the five grooves on each of said opposing walls, upper and lower grooves 485u and 485l, serve as guides that support and allow lateral movement of a pair of interlocking snap plates 481L and 481R. The interlocking snap plates 481L and 481R are configured to engage (similar to function 490r) the clamp bars 474a and 474b while allowing the user to rotate them together by rotating the lever bars 469, similar to the rotation of the lever bars 459 of the embodiment shown in FIG. 5A.

The interlocking snap plates 481L and 481R are laterally slidable along grooves 485u and 485l to which they are slidably attached by means of engaging projections, such as projections 477, provided in the corner regions of each of the interlocking plates.

Clamping rods 474a and 474b are laterally slidable through a third of five grooves provided on each of said opposing walls. The third groove 475 (located below near said upper groove 485u) is a through groove for the clamping rods 474a and 474b configured to allow lateral movement thereof, and has a circular flare 475B in its middle region configured to rotate smoothly after reaching the center grooves and mutual fixation (with the top of the compressible package 402 sandwiched between them) by means of interlocking snap plates 481L and 481R. Each of the interlocking snap plates 481L and 481R includes a semicircular recess configured to receive a corresponding one of the clamping rods 474a and 474b such that when they snap together, the mirror semicircular recesses together form a circular hole corresponding to the circular flare 475B which allows for smooth rotation latching clamp bars 474a and 474b through mutually latching plates 481L and 481R.

The illustrated device 270 is different from the device 250 in FIG. 5A primarily in that it includes a pair of limiting bars 471a and 471b designed to stop the inflated portion of the compressible bag 402 from rising and reaching the clamping bars 474a and 474b when rotating to inflate the inflatable container of the two-piece structure 400.

The limiting rods 471a and 471b (also referred to in the description as limiting elements) are movable, respectively, by means of a fourth (483a) and a fifth (483b) of five grooves provided on each of said opposing walls. Grooves for limiting grooves, i.e., by means of grooves 483a and 483b, each of which has an L-shaped contour having a horizontal groove segment configured to provide lateral movement of the corresponding limit rod, and a vertical groove segment configured to provide vertical movement the corresponding limiting rod, after reaching, through its lateral movement, the area closest to the axis of rotation of the clamping rods 474a and 474b. A vertical segment of each of the L-shaped grooves extends downward from the corresponding end of the corresponding horizontal groove segment so that after the limiting rod reaches the end of the lateral segment of the L-groove closest to the axis of rotation of the clamping rods, the limiting rod can move (and in in preferred embodiments, is free to fall for at least the first few millimeters) down the vertical segment of the L-shaped groove. The limiting rods are engaged by interlocking snap plates 481L and 481R within respective vertical grooves 481g such that lateral movement of the constraint rods corresponds to simultaneous lateral movement of a corresponding one of the interlocking snap plates 481L and 481R. In the same manner, each of the clamp bars 474a and 474b may be engaged by a corresponding semicircular recess in the interlocking snap plates 481L and 481R by means of a semicircular wheel member (not shown) such that the lateral movement of the clamp bar also corresponds to and is simultaneous with the lateral movement of the interlocking snap plates 481L and 481R. Once closed by lateral movement, the semi-circular wheel elements of each of the interlocking snap plates 481L and 481R are snapped together by a common releasable coupling means to form a rotatable wheel rotatable within the circular opening defined by the semi-circular recesses, thereby allowing rotation of the clamp bars 474a and 474b by using the lever rods to wind the compressible package around the rods, similar to the winding of the embodiment shown in FIG. 5A.

In various preferred embodiments, vertical grooves 481g extend through flexible vertical projections 481p projecting outward from interlocking snap plates 481L and 481R, respectively, and tightly abutting the limiting rods such that, after manually displacing the limiting rod (using handles 481k on its ends), to the bottom of the corresponding vertical groove, it will remain stationary during the operating mode when inflating the inflatable device, thereby preventing the inflatable part of the compressible package from being lifted by the limiting rods.

After suspending the two-piece structure 400 with the vertical pins 499, and prior to filling and final preparing the mixture, the closure of the clamp bars 474a and 474b will result in the top of the compressible feed package 402 being clamped between the clamp bars in an area along their common axis of rotation 490a. In various embodiments of the present invention, each of the clamping rods may have a star-shaped cross-section in a transverse direction to its longitudinal axis. The clamping rods 474a and 474b can then be rotated by the user, thereby winding the compressible package 402 and reducing its volume. The remainder of the operating description of the device can be understood after reading the operating description as applied to the 250 device.

In fig. 6A-6C show the liquid receiving port 600 of the baby feeding device 311 with its inflatable container 312 shown before inflation (in this case, FIG. 6C only shows part 312 of the baby feeding device; the full view can be seen in FIG. 3). The inflatable container 312 is an inflatable portion of a two-piece structure according to various embodiments of the present invention. The liquid receiving conduit 600 comprises a cylindrical wall 601C, a plug 601 having an annular rim 601e for insertion into the lower portion of an elastic inflatable sleeve 312 constituting an inflatable container. In fig. 6C the plug is shown in position (inverted from the position shown in FIG. 6A, corresponding to its position in the filling device shown in FIG. 3) inside the sleeve 312 with a pressure ring 315r pressing the end portion of the sleeve 312 into the annular recess 601r , made in a cylindrical wall 601c. Thus, the sleeve is permanently attached to the fluid receiving port 600 to compensate for involuntary forces that may be exerted by the user when using the device. A semi-rigid security device 315 having a circular hole aligned with the outer circumference of the pressure ring 315r is latched into the pressure ring by inserting the edge of the security device that collides with the circular hole into a corresponding annular groove in the pressure ring. The fluid receiving pipe 600 contains a one-way valve that allows liquid under pressure from the compressible bag 302 to be introduced into the inflatable sleeve 312, while preventing reverse flow from the sleeve 312 to the outside of the pipe 600. The one-way valve contains at least one hole 602 made in a cylindrical wall 601c a few millimeters (e.g., within 3 to 12 mm) away from rim 601e. The elastic ring band 603 is installed on the cylindrical wall 601c under the end rim 601e. The tape 603 is sized to fit snugly against the cylindrical wall 601c to generally seal the holes 602 from fluid passage by pressure between the annular tape 603 and the cylindrical wall 601c in which the holes 602 are formed.

The fluid pressure within the inflatable sleeve 312 will increase the pressure of the annular band 603 on the cylindrical wall 601c, thereby improving the seal of the holes 602 and preventing fluid from leaking from the inflatable container through the fluid receiving port 600. In contrast, when a liquid pressure greater than the pressure inside the inflatable sleeve 312 is forced into the liquid receiving port 600 through its hollow neck 601h, the pressurized liquid will force the annular band 603 through the holes 602 away from the cylindrical wall 601c, thereby allowing the liquid under pressure enter the inflatable sleeve 312 through the formed temporary gap under the specified fluid pressure between the annular band 603 and the cylindrical wall 601c. Thus, as long as the filling device squeezes the elastic bag 302 under emptying pressure with the amount of liquid contained in the bag, the liquid will flow out of the bag 302 into the inflatable container 312. Once the influx stops (due to the removal of compressive pressure from the bag 302 or how this may occur, for example, when all the liquid contained therein has been transferred into the inflatable container 312), backflow from the inflatable container 312 is prevented by an annular band 603 resealing the holes 602 under the pressure of the liquid inside the inflatable container. The fluid receiving connection 600 may include a flange portion 601f to facilitate connection with a connecting member 305 that is an outlet of the elastic pouch 302. The flange portion 601f may include a thread corresponding to a mating thread formed in the connecting member 305. In various embodiments, the connection between the connecting member element 305 and fluid receiving port 600 is effected by frictional fitting, with or without mutual engagement of the partially rotating parts (i.e., parts that engage and are held together by a corresponding partial rotation).

In fig. 7A illustrates a vertical cross-sectional exploded view of three elements of another embodiment of a liquid receiving port 700a of a baby feeding device that is part of an inflatable container of a two-piece structure according to various embodiments of the present invention. The three elements are a flexible valve diaphragm 710, a tubular diaphragm retaining member 701i, and a manifold body 720. When installed together, the valve membrane 710 is placed on a flat base surface 710b, which is the outer surface of the wall base 720b (labeled in FIG. 7D) facing the inflatable container 311 (not shown here). In various embodiments of the present invention, the membrane is made of silicone rubber and is attached to the surface of the base through the lower edge of the tubular wall 701 of the tubular membrane retaining member 701i. A plurality of, for example, four, pointed projections 701p project downwardly beyond the bottom of the tubular wall 701. The pointed projections are pressed into the membrane 710 at corresponding, for example, four points near their ends to better compress the membrane between the base surface 710b and the retaining element 701i. A liquid inlet 720a is provided through the wall base 720b and is sealed toward the inflatable container by said valve membrane 710.

A pair of semicircular recesses 701r are formed in the lower portion of the tubular wall 701 of the retaining member 701i, thereby allowing the valve membrane 710 in the recessed areas to be separated from the valve base surface 710b. The recesses are formed at opposite ends of the common diameter line (i.e., located at an angle of 180 degrees from each other on the circumference of the tubular wall 710). The tubular member 701i has a predetermined mounting position on the nozzle body 720 due to the mating protrusion and snap connections 701s to 720s with the holes through which the tubular member 701i is secured to the nozzle body 720. When positioned in position, the semicircular recesses 701r align with holes 720o formed through the cylindrical wall 720c just above the base surface 710b. Holes 720o allow fluid connection between the inflatable container 312 (see FIG. 6C) and the interior of the tubular member 701i via the semicircular recesses 701r. The inflatable container 312 may be fixedly attached to the cylindrical wall 720c of the nozzle body 720 in a manner similar to the attachment between the inflatable container 312 and the cylindrical wall 601c in the embodiment illustrated in FIG. 6A–6C. The annular recess 720r (similar to the annular recess 601r) provides connection via a corresponding clamping ring (similar to the clamping ring 315r) and additionally contains bosses 721 for anti-slip retention. Thus, when the pressure inside the inflatable container exceeds the pressure in the hollow space 720h of the liquid receiving pipe, the pressure will be communicated through the holes 720o and the semicircular recesses 701r on the top of the valve membrane 710, thereby subjecting it to pressure against the base surface 710b and sealing the hole 720a, as illustrated by the position of the membrane in FIG. 7D.

Conversely, when the pressure in the hollow space 720h exceeds the pressure of the liquid inside the inflatable container (for example, due to compression of the elastic bag 302 by the filling device to supply liquid therefrom to the inflatable container 312), the pressure will communicate through the valve opening 720a to the bottom of the valve membrane 710 , thereby deforming the membrane, as illustrated in FIG. 7E (in FIGS. 7D and 7E, the valve membrane 710 is marked with a "xxxxx" pattern for ease of recognition), so that liquid can flow between the base surface 710b and the bottom of the membrane 710 in the recessed semicircular areas 701r into the inflatable container 312 through the openings 720o.

After the pressure in the hollow space 720h becomes less than the pressure of the liquid inside the inflatable container, the valve membrane 710 will again be pressurized toward the valve base surface 710b, thereby preventing backflow from the inflatable container.

An advantage of the liquid receiving pipe illustrated in FIG. 7A-7E is that liquid can be withdrawn from the inflatable container by a syringe because the opening 720a and the valve membrane 710 on top of the opening are accessible and permeable to the syringe needle. In addition, since the inflatable container is disposable, it is possible to extract liquid from the inflatable container even into a syringe without a needle. A syringe without a needle may intentionally attach itself to the manifold body 720, displacing the valve membrane from its position (even by rupturing it or causing it to be irreparably damaged) by pushing it with the tip of the syringe inserted into the hole 720a through the cavity 720h of the cylindrical wall 720c.

The flange 720f defines the boundaries of the ring recess 720r from its bottom and defines a connection region between the side projections 722 and the flange 720f for connecting the liquid outlet of the elastic pouch 302 having a common connecting means 305, for example, by a partial rotation connecting method. Alternatively, a friction connection may be provided between the outlet of the elastic bag and the liquid receiving port 700a of the inflatable container 311. In various other embodiments, mating threads are provided between the corresponding holes to make the connection. From a design perspective, the threads may be either internal on the inner surface of the cylindrical wall 720c (facing cavity 720h) or on the outer surface of the cylindrical wall 720c (e.g., in embodiments that lack side projections 722).
