Description

The present invention relates to baby bottles, in particular single use disposable baby bottles comprising a suction unit, a container and a handle ring, and a kit for a disposable baby bottle and a disposable baby bottle and cup system.

Conventional baby bottles usually consist of a container, a nipple and a ring cover, with which the nipple is attached to the container. The ring cover is usually screwed to the container, namely to a thread on the outside of the container opening.

Reusable bottles must be sufficiently cleaned and sterilized to prevent the filled drinks, e.g. bacterial, contaminated. Sterilization is time consuming and, if not expertly or inadequately cleaned, remains of residues may be left exposing the child to risk.

Various approaches for one-way bottles are known in the art.

A step towards the rational production of a disposable bottle consists in a reduction of the components. For this purpose, the mouthpiece of the nipple, usually made of a flexible material, and the ring cover, usually made of another, more rigid material, are joined together to form a part, as in US 2004/0256345 and EP 0 300 786 released.

In DE 35 35 653 and EP 0 300 786 In addition, foldable containers are proposed, which fold in particular harmonica-like are. For delivery, storage and disposal of such containers take up little space and the volume can be increased during filling.

DE 35 35 653 shows a harmonious foldable container whose head portion has been subjected to a hardening process in the vicinity of the container opening in order to be able to engage with the ring Überwurfs.

In order to force a single use of the bottle, the suction unit can be secured to the container by means of a snap-lock, as in US 2004/0256345 and the documents cited therein. Once the bottle has been filled and closed, it can not be opened again for visible refilling without visible damage.

The FR 2 779 946 describes a Babyfaltflasche, which is stored in a protective cup before use. The cup is sealed with a protective film which must be removed before use.

The previously known one-way bottles are either unwieldy to use or complicated and expensive to manufacture. Foldable bottles also have stability problems, especially in the area of the neck of the bottle during the transition from the bottle to the nipple. Conventional folding bottles also have the disadvantage that the correct unfolding is difficult to control before filling.

The object of the invention is to avoid the disadvantages of the known, in particular to provide a simple disposable bottle, which provides a comfortable and hygienic use and which is efficient and economical to produce.

This object is achieved according to the invention with a disposable baby bottle with a foldable container made of a flexible, liquid-tight plastic material, a suction unit and an intermediate element which is connected or connectable on the one hand with an opening portion of the foldable container and on the other hand with the suction unit, preferably without visible damage or destruction insoluble is connected or connectable, wherein the intermediate element is more dimensionally stable than the foldable container, in particular as the opening portion of the foldable container, wherein the suction unit has a preferably central or centrally located suction area for receiving in the mouth, in particular of an infant, of a substantially flexible, in particular elastic , Material having a liquid outlet and a substantially dimensionally stable annular region, and further wherein the suction region and the annular region are integrally formed.

Bottles with foldable containers can be delivered and stored in a very space-saving way. After being unfolded for use, the bottles provide sufficient internal volume. For disposal, the containers can be folded again to save space. The plastic material for the container is flexible, that is, it is so adapted in thickness and / or material and / or shape that the container can be easily folded together and unfolded. Preferably, the foldable container has a small wall thickness, which allow the folding of the container with a certain material. For one-way bottles, it is convenient to use foldable container with low wall thickness, which are inexpensive because of material entry, but also mechanically little claim. This can be detrimental to the handling and the possibility affect the liquid-tight connection. The intermediate element compensates for this disadvantage.

For example, wall thicknesses for the foldable cup can advantageously be less than approximately 2 mm. Wall thicknesses of 0.6 mm to 0.2 mm are particularly well suited, especially when using EVA (ethylene vinyl acetate) or LDPE (low density polyethylene) material for producing the bottle. These materials are cost-effective to manufacture, meet the requirements in the food industry and allow various possibilities for the outer contour.

With regard to one-way bottles, lightweight and flexible materials are advantageous for the transport of even large quantities and practical for disposal due to the small footprint.

Like all baby bottles, the disposable baby bottle according to the invention comprises a container for holding the beverage, e.g. of milk, tea, juice or even porridge, and a suction unit with a mouthpiece for sucking up a child, a patient or an animal.

According to the invention, the two essential components, namely foldable container and suction unit, can be coupled to the intermediate element. Before filling either the intermediate element with the container or the intermediate element may be connected to the suction unit. The second connection, either to the suction unit or to the container leads to the liquid-tight coupling of suction unit and container, so that the filling can emerge exclusively through the designated liquid outlet in the mouthpiece of the suction unit.

In order to give the foldable container a sufficient dimensional stability, this is connected or connectable at its opening area with an intermediate element.

The intermediate element ensures that a liquid-tight connection between the suction unit and the foldable container is made possible, regardless of the nature of the components. Preferably, these components are permanently connected or connectable without visible damage or destruction. The intermediate element also serves to produce a non-removable, in particular without visible damage or destruction connection with the suction unit. After filling the baby bottle, the suction unit is permanently connected to the intermediate element. This ensures that a refilling of the bottle is prevented, or is immediately recognizable if the suction unit has already been removed once from the intermediate element. It goes without saying that in this case, the container and the intermediate element must be non-detachably or non-destructively releasably connected to each other. The connection of suction unit and intermediate element is thus only by destroying, e.g. Cutting the suction area or cutting the intermediate element with a sharp object solvable. At least one forcible release of the connection leaves visible traces on the intermediate element or on the suction unit.

It is also crucial that the intermediate element is more dimensionally stable than the foldable container, or as the portion of the foldable container, with which the connection is received, so usually the opening area of the container. Dimensionally stable here means that the intermediate element in the hand of the user has a strength which ensures the maintenance of the external shape and the maintenance of the flow opening.

This also stabilizes the opening area of the foldable container, resulting in an overall more stable arrangement of the disposable baby bottle.

Due to the dimensional stability, the intermediate element is shaping the connection area and defines the opening area between the foldable container and the suction unit.

Preferably, during manufacture, a liquid-tight and preferably insoluble compound is produced, for example, by gluing or welding between the intermediate element and the foldable container. However, other connections such as screw, bayonet or clamping / latching connections can be provided. The opening region of the foldable container preferably encloses a substantially cylindrical neck of the intermediate element.

The suction unit comprises a preferably centrally or centrally arranged suction area. The suction region can also be arranged peripherally, that is to say outside the center of the suction unit.

The suction area preferably has a shape and flexibility that are comfortable for the baby, who either adapt to the jaw or simulate a mother's breast. The liquid outlet is preferably shaped so that a discharge of the liquid is possible as soon as the child sucks. In addition, the liquid outlet may have "drip-stop" characteristics. Preferably, the suction area is made of elastic material such as e.g. TPR (thermoplastic) or EVA made.

The ring area is used for liquid-tight connection with the intermediate element and thus with the foldable container. Moreover the function of the annular region is to stiffen the transition region between the container and the nipple and to increase the dimensional stability of the intermediate element. The ring area is therefore preferably dimensionally stable, for example, the ring area is made of a dimensionally stable PP (polypropylene).

Suction units may be provided with a specific liquid outlet which is particularly suitable for the discharge of liquids of certain viscosity, for defined quantities of liquid or for the suction power of children of a certain age. Alternatively, the suction unit may comprise a Vario system, which allows the selection and adjustment of different liquid outlets. The suction area and the ring area are integrally formed. The term one-piece is to be understood as meaning that suction area and ring area are inseparably connected respectively can only be separated by destruction or damage. Preferably, the two parts have been joined together in the production, in particular welded, glued or sprayed. The suction unit can also be produced from a material in one casting, wherein subsequently the ring area is hardened and stiffened. The one-piece design makes it easier to use when assembling the bottle and reduces the number of components.

In a preferred embodiment, a holding element for gripping the disposable baby bottle is provided on the intermediate element.

In particular, in bottles having a flexible or foldable container, it is advantageous if the bottle has a holding element as an additional grip surface, on which the user who holds the bottle for feeding, they can touch the same without exerting pressure on the container becomes and this deforms or liquid is forced out. The gripping surface can be formed by the intermediate element and enlarged by the holding element.

In a preferred embodiment, the retaining element is attached to the intermediate element, either integral therewith or attached thereto as a separate component. Preferably, the annular region is substantially disc-shaped for stiffening the intermediate element. The disc-shaped annular region portion is preferably approximately in a plane perpendicular to the longitudinal axis of the baby bottle. As a result, the intermediate element is additionally stiffened by the rigid annular region when the suction unit is connected to the intermediate element. This prevents deformation of the intermediate element caused by radial forces when holding the bottle on the intermediate element.

The disk-shaped annular region portion is advantageously at least partially on the end face of the intermediate element and thus forms a seal between the intermediate element and suction unit.

In a preferred embodiment, the annular region has a fastening ring, which is designed such that it can be positively and / or non-positively engaged or snapped into a ring slot arranged on the end face of the intermediate element.

When the disposable bottle is delivered in a state in which the intermediate member and the foldable container are already connected, the bottle is filled for use and closed by the user by means of the fastening ring. The connection Ideally, therefore, it should not only be liquid-tight, but must also be produced in a few simple steps.

In a preferred embodiment, the fastening ring forms together with the more central resp. ring-shaped annular area an angle of preferably around 90 °.

In a further preferred embodiment, the fastening ring has at least one resilient snap-lock element, which engages when closing on a counterpart which is provided on the intermediate element, in particular in a ring slot on the end face of the intermediate element. Of course, the arrangement could also be reversed, ie fastening ring with snap-lock element on the end face of the intermediate element and annular slot on the ring area.

The arrangement of the annular slot in the end wall of the intermediate element, there is virtually no way to solve the connection non-destructive.

The one-piece suction unit is preferably formed as an injection molded part, a pressing process part or a transfer molding process part.

In a preferred embodiment, the foldable container comprises a folding bellows extending in a longitudinal direction, which has a plurality of foldable ring sections for stiffening the folding bellows, wherein the folding bellows is foldable or harmonic-like in the longitudinal direction.

The foldable ring sections stiffen the bellows, so that the container is not pressed in the radial direction when holding. The ring sections resp. Wrinkles of the bellows run in usually parallel to the opening surface and the bottom of the foldable container. In certain applications, however, it could also run at a different angle to the opening area.

The ring sections preferably each have two different length wrinkle surfaces, which are each bounded by a fold edge. Due to the different length wrinkles surfaces is made possible that the container can remain relatively stable in a folded position and in an unfolded position of use. Of course, it is also possible to fold a part of the ring sections together and leave a part unfolded. The volume of the container can thereby be adapted to the level of the container.

It goes without saying that the foldable container can also have fold surfaces that spiral around the longitudinal axis. In contrast to the harmonica-like folding, in which wrinkle surfaces of different inclinations alternate along the axis, the spiral or helical wrinkle surfaces form contiguous regions on the inside of which the liquid can run.

The length of the wrinkle surfaces may vary only minimally or even be identical. This makes it possible to achieve a more compact form in the folded state.

In a further embodiment, the foldable container at the lower closed end on a stiffer than the other ring sections formed, in particular not collapsible ring portion. The lower closed end of the foldable container is opposite to its opening area. For this ring section stiffer than the overlying Ring sections may be, this ring portion preferably has a greater wall thickness than the other ring sections.

Preferably, the bellows can be bent from its unfolded position, so that the bellows has a curved shape and remains in this position, that is, the ring sections have folded and unfolded sectors.

In a further embodiment, one or more ventilation valves are arranged on the suction unit. The valves are preferably one-way valves that allow air to flow only into the baby bottle to equalize the negative pressure created when sucking at the fluid outlet. Ideally, the valves are designed so that no liquid escapes through them.

In another preferred embodiment, the foldable container is glued or welded to the intermediate element. Particularly suitable is a compound produced by ultrasonic welding. The connection is possible, for example, by direct injection of different injection plastics. The foldable container preferably has no fold surfaces at the opening region, at which connection to the intermediate element can take place. Intermediate element and foldable container can be made in one piece, for example, by extrusion blow molding or injection blow molding. In this process, a blank with a final intermediate element by blow molding receives a new shape and the container is provided with fold surfaces and fold edges. The connection between intermediate element and foldable container is preferably already in the production.

The object of the invention is further solved by a kit for forming a disposable baby bottle, which a foldable container made of a flexible, liquid-tight plastic material, a suction unit and an intermediate element, which is connected or connectable to an opening portion of the foldable container on the one hand, wherein the intermediate element with the suction unit, preferably without visible damage or destruction is permanently connected, the Intermediate element dimensionally stable than the foldable container, in particular as the opening portion of the foldable container, the suction unit having a preferably central or centrally located suction region of substantially flexible, in particular elastic, material having a liquid outlet and a substantially dimensionally stable annular region, and further the suction region and the annular region are integrally formed.

A further aspect of the invention relates to a system comprising a disposable baby bottle with a foldable container, an intermediate element and a suction unit, and further comprising a cup-shaped container for receiving the, in particular folded, disposable baby bottle, wherein the cup-like container and the intermediate element in shape and / or dimensions are adapted so that the cup-like container can be releasably applied from an underside of the disposable baby bottle for, in particular complete, receiving the disposable baby bottle as well as from an upper side of the disposable baby bottle in an inverted position to protect the suction unit mounted on the intermediate element.

The disposable baby bottle can therefore be stored in the cup-like container, in particular before its first use. As long as the disposable baby bottle is in the cup-like container, the inner volume of the foldable container is preferably reduced, for example by virtue of the foldable container being bellows-like folded up. A foldable container made of a baggy material can also be rolled up or otherwise compressed in the cup-like container. For the use of the baby bottle, it is taken from the cup-like container, filled and closed with the suction unit. If not drunk from the baby bottle, the cup-like container protective over the suction unit can be applied. To drink from the bottle, the cup-like container can be solved at any time from the baby bottle. Preferably, this connection is manually and without tools solvable. The cup-like container must therefore not be destroyed to release the connection, so that the cup-like container can be repeatedly detached from the baby bottle and reapplied.

The cup-like container is preferably made of a dimensionally stable plastic such as PP and preferably has a wall thickness of 0.8 mm to 0.2 mm. This ensures adequate protection against external influences.

Preferably, the cup-like container is releasably connected or connectable by means of a clamping, latching or screw connection with the intermediate element.

In a further advantageous embodiment, a particularly substantially cylindrical connection region, in particular a clamping region, adjoins the edge of the cup-like container, the inner diameter of which is adapted to the outer diameter of the intermediate element such that a positive and / or positive connection between the intermediate element and the cup-like container, in particular a clamping connection can be produced.

A clamping connection is formed, for example, by the inner diameter of the connecting region being slightly smaller than the outer diameter of the intermediate element. In addition to a cylindrical connection area, a conical connection area is also possible. Preferably, the connection region is conically tapered against the container bottom. As a result, the clamping effect increases, the farther the cup-like container is pressed toward the bottom of the baby bottle.

Adjacent to the connection region, in particular to the clamping region of the cup-like container, a stop for the intermediate element and / or the holding element is provided in a further preferred embodiment, which limits the connection region of the cup-like container with the intermediate element. The cup-like container is preferably pushed so far over the intermediate element until the stop against the intermediate element, in particular at least partially abuts against the end face. This prevents the cup-like container from being pressed so firmly onto the baby bottle that the cup-shaped container could be damaged.

The stop can be arranged so that the bottom of the cup-like container in its placed on the baby bottle position sealingly against the liquid outlet of the suction unit. This prevents accidental leakage of the liquid from the baby bottle. This is particularly advantageous if the liquid outlet would have no "drip stop" properties.

In a particularly preferred embodiment, connecting means for releasably connecting the two containers are provided to each other on the cup-like container and / or the foldable container, which upon removal of the foldable container from the cup-like Receptacle positively and / or non-positively in the region of the bottom of the foldable container so that the foldable container is in particular completely folded into its position of use, when the foldable container is removed from the cup-like container.

The foldable container preferably stores in the folded position in the cup-like container. For use of the baby bottle, these or their components are removed from the cup-like container. By the connecting means causes the foldable container is unfolded during removal. For this purpose, the holding force between the cup-like container and the foldable container is preferably greater than the force necessary to bring the foldable container from the collapsed to the unfolded position.

In harmonious collapsible containers, the outer diameter in the folded state may be slightly larger than in the unfolded state. In another embodiment, the connecting means may consist in that the inner diameter of the cup-like container is slightly smaller than the outer diameter of the foldable container in the folded state. Ideally, this inner diameter is greater than the outer diameter in the unfolded state. This results in a clamping action between foldable and cup-like container only when the foldable container is folded in the cup-like container.

The connecting means may also be formed in that the inner wall of the cup-like container is tapered towards the bottom conically such that against the bottom increases the clamping action between the inner wall and container.

The rejuvenation causes, especially in foldable containers with a substantially constant diameter, the largest holding force at the narrowest point, ie in the bottom region of the cup-like container occurs. Thus, the bottom portion of the foldable container dissolves last from the cup-like container. Ideally, the inner diameter of the cup-like container is matched to the outer diameter of the collapsed container, that the foldable container has fully unfolded before the connection between the two containers dissolves completely.

The cup-like container can be conically tapered over its entire length. In addition, a stop may be provided, for example in the form of a circumferential bead. In another preferred embodiment, the cup-like container has only one in the bottom region conical tapered inner wall, which extends substantially only to over the lowermost ring portion of the foldable container. Outside the conical region of the cup-like container is preferably cylindrical in shape. The cylindrical portion may be stepped cylindrically formed, wherein preferably a shoulder forms a stop as a transition between two cylindrical sections of different diameter.

Preferably, the connecting means comprise at least one circumferential, radially inwardly projecting bead on the side inner wall of the cup-like container, wherein the bead is latched or latched to an outer, in particular of the bottom closest folding edge of the foldable container.

The bead does not necessarily have to be completely encircling. Also conceivable are one or more bead segments lying in a common plane, which on the inner wall of the cup-like Container are arranged.

The connecting means comprise in another preferred embodiment, one or more substantially parallel to the longitudinal axis, in particular at the foot of the inner side wall of the cup-like container, arranged ribs which project radially inwardly such that the foldable container is clamped or clamped by the ribs.

If the ribs are arranged at the foot of the side inner wall, they preferably extend at least to the bottom nearest outer folding edge of the foldable container when it is mounted in the cup-like container.

Basically, a rib can be enough to clamp the folded container. In this case, the rib pushes the foldable container against the wall opposite the rib, so that the foldable container is clamped. Preferably, however, three ribs are arranged offset by 120 °, which clamp the foldable container.

In another preferred embodiment, the intermediate element, the foldable container and the suction unit are stored or storable as separate parts in the cup-like container. For use, the components must be removed from the cup-like container, intermediate element and foldable container may need to be connected. Subsequently, the foldable container can be filled and closed with the suction unit. Finally, the cup-like container can be placed on the baby bottle.

The suction unit is preferably in an inverted position with the suction region projecting into an opening region of the foldable container stored or storable on the intermediate element and / or the foldable container in the cup-like container. This ensures a space-saving storage and reduces the height of the cup-like container, which has a positive effect on the cost of materials.

In a further preferred embodiment, the cup-like container can be closed or closable by a closure, in particular a guarantee closure, so that the disposable baby bottle in the cup-like container is closed, in particular sterile, packaged or packable.

Particularly suitable as a closure are films which are adhered to the edge of the cup-like container. The film may be made of plastic or metal, as aluminum foil prove to be particularly advantageous. Also suitable are plastic (e.g., PP) coated aluminum foil or plastic coated paper.

The closure not only ensures sterile packaging, it also prevents the escape of any partial filling such as milk powder and ensures its durability.

In a further embodiment, volume measurements and / or measurement scales can be arranged on the foldable container and / or the cup-like container. This allows the determination of the amount of liquid in the containers. Volume measurements in the cup-like container have a higher accuracy, since the volume of foldable containers varies because of their flexibility.

Further individual features and advantages of the invention will become apparent from the following description of the embodiments and from the drawings.

1 shows a disposable baby bottle 1 comprising a foldable container 2, an intermediate element 13 with a holding element 6, which is integrally connected to the intermediate element 13, and a suction unit 3 consisting of a centrally arranged suction region 4 and a ring region 5.

The foldable container 2 has a bellows 9 with foldable ring sections 11. Each ring portion 11 each has a longer pleat surface 12 and shorter pleat surface 12 '. Two adjacent fold surfaces each include a fold edge 8. In the upper area of the foldable container is the opening area 16.

At the ring area 5, a fastening ring 14 adjoins, which is provided with a snap-lock element 26.

The intermediate element 13 can be connected to the suction unit 3, wherein after the connection, the intermediate element 13 is reinforced by the annular region 5 of the suction unit 3.

The disposable baby bottle 1 preferably holds a volume of about 250 ml and has a preferred diameter of 4-7 cm, more preferably about 5.5 cm.

In FIG. 2 and all following figures, the same reference numbers refer to the same elements. The suction unit 3 is not connected in this example with the intermediate element 13 and is shown in an inverted position, as stored in the cup-like container 15 ..

The intermediate element 13 has an end face 27 on which a ring slot 7 for accommodating the fastening ring 14 and a sealing lip 28 is arranged (cf. also the following FIG. 6). The cup-like container 15 has an edge or a bottom 17 and has a stop 19 below the connecting region 18.

The suction area 4 is provided with a liquid outlet 38.

FIG. 4 shows a ring portion 5 of the suction unit formed as a separate part, before it is integrally connected to a suction region (not shown). The annular region is formed, for example, as an injection molded part from a dimensionally stable plastic.

The snap-lock element 26, together with the previously mentioned sealing lip, ensures a fluid-tight connection with an intermediate element not shown in the figure.

The annular region 5 has on its inner side 30 a portion 31 of lesser thickness, which has a plurality of circular recesses 32.

In the production of a one-piece suction unit, the portion of lesser material thickness 31 is encapsulated with a flexible and in particular elastic material, which thereby fills the recesses 32 so that the elastic material, which forms a suction, can not be connected non-destructively releasably connected to the ring area.

The connection between the central suction region of the suction unit (not shown in the figure) and the annular region 5 must be liquid-tight and withstand the suction stress when drinking. The recesses 32 enhance the mechanical stability of the connection.

FIG. 5a shows a stepped cylindrically shaped cup-shaped container 15: an upper cylindrical section forms a connection region 18 for the intermediate element (not shown here). A conical transition between the cylindrical sections forms a stop 19 for the intermediate element. The cup-like container 15 is closed with a closure 24 here, for example as a blister film 36 shown on an edge 17, and thereby keeps the contents of the cup-shaped container 15 sterile.

In FIG. 5b, the suction unit 3, the intermediate element 13 and the foldable container 2 lie completely within the cup-like container 15. The foldable container 2 is mounted in its folded position in the cup-like container 15 with the side inner wall 21.

Evidently, the suction unit 3 lies in an inverted position on the end face 27 of the intermediate element 13 in FIG. 5 b.

The intermediate element 13 rests on the stop 19 of the cup-like container 15. The intermediate element 13 has a connection piece 29, on the outside of which the opening region 16 of the foldable container 2 is fastened. The annular slot 7 has an inwardly projecting edge 33, which can form a latching connection with the snap-lock element 26 of the fastening ring 14 on the end face 27 of the intermediate element 13.

In Figure 6, the nipple unit 3 is shown in the (i.e., snapped-on) position associated with the intermediate element 13. The fastening ring 14 is in this position in the annular slot. 7

When inserting the fastening ring 14 into the annular slot 7, the hook-shaped snap-lock element 20 is pressed by an edge 33 against the fastening ring 14. As soon as the snap-lock element 20 has passed the edge 33, the snap-lock element 26 engages in an undercut 34 of the edge 33 and the suction unit 3 is thus permanently connected to the intermediate element 13 without visible damage or destruction.

The end face 27 is provided in this example with a sealing lip 28 which bears sealingly against the inner side of the flexible suction region 4.

Figures 7a and 7b show a cup-shaped container 15 with a cylindrically shaped connection portion 18 and then the stop 19. The stopper 19 follows a conically tapering down trained area of the cup-like container 15, which is provided for receiving the bellows (not shown here ). The cup-like container 15 has on the side inner wall 21 a volume measurement 25.

The cup-like container 15 in Figures 8a and 8b, in contrast to the cup-like container according to Figure 5b on its inner side wall 21 has a circumferential bead 22.

The bead 22 is shown in greater detail in FIG. 8c. The bead 22 is shown here as a bead 22 which runs over the entire inner side surface 21 and serves as a connection means for the foldable container.

In FIG. 8d, the folded disposable baby bottle 1 is mounted in the cup-like container 15. Again, the suction unit 3 is stored space-saving in an inverted position on the intermediate element 13. The circumferential bead 22 on the inner side wall 21 of the cup-like container 15 engages over a lowermost fold edge 8 'and forms a detachable connection between cup-like container 15 and the foldable container 2. The longer fold surfaces 12 are below, the shorter fold surfaces 12' above the outer fold edges 8. As a result, the folded edges 8, 8 'form a barb-like surface. The resistance of the folding edge 8 'opposite the bead 22 is thereby increased.

The cup-like container 15 in Figures 9a and 9b has on its inner side wall 21 a circumferential bead 22 analogous to Figures 8a / 8b. However, between the bottom of the cup-like container 15 and the bead 22, the side inner wall 21 has a conically tapered, inwardly angled side wall portion 35. By the conically inwardly angled side wall 35 of the foldable container is not only detachably connected by the bead 22 but also by the clamping action of the tapered side inner wall 35. This results in a firmer connection between cup-like container 15 and the foldable container 2.

As can be seen in FIG. 9 c, the tapered side inner wall 35 preferably directly adjoins the bead 22.

Figure 9d shows that the foldable container is connected not only to the bead 22 but also through the tapered sidewall portion 35 to the cup-like container. The cup-like container 15 clamps a ring section 11 firmly.

The disposable baby bottle 1 of Figures 10a and 10b corresponds to the embodiment shown in the previous figures. The cup-like container 15 in FIGS. 10a and 10b has a rib 23 at the foot of the side inner wall 21. The rib 23 extends parallel to the longitudinal axis 10 (which defines the longitudinal direction) from the bottom of the cup-like container 15 along the side inner wall 21 to a length which corresponds approximately to the height of a foldable annular portion 11.

As can be seen in Figure 10c, the rib 23 extends from the bottom of the cup-like container 15 along the side inner wall 21 in the longitudinal direction.

FIG. 10d shows three ribs 23 which are each arranged offset by 120 ° on the side inner wall 21 in the bottom area. Thereby, the lowermost ring portion (not shown in FIG. 10d) in the cup-like container 15 can be clamped.

The cup-like container 15 according to FIG. 11 is uniformly tapered conically from top to bottom in the example shown here. The clamping action between side inner wall 21 and bellows 9 thus concentrates on the lower region of the cup-like container 15 and is additionally reinforced by the bead 22. Optionally, the side inner wall could also have a stop (not shown) on which the intermediate element could rest.

FIG. 12 shows a cup-shaped container 15 which, in contrast to the cup-type container according to FIG. 11, has a continuous cylindrical shape from the upper edge 17 to the bottom.

FIGS. 13a and 13b show a second example of a disposable baby bottle 101 according to the invention. The lowermost ring section 111 is designed here as a non-foldable ring section, which is more dimensionally stable / stiffer than the other ring sections 11. Preferably, therefore, the wall of the ring portion 111 is thicker than the other ring portions 11 formed. The ring portion has no folding edges here and is curved in cross-section and not shaped as pointed in the ring sections 11. Of course, other forms are conceivable. The ring portion 111 is clamped in the tapered side wall portion 35 and this results in a better clamping effect with the cup-like container 15. The lengths of the pleat surfaces 12 and 12 'differ only slightly in the example shown here.

FIG. 14 a shows a cup-like container 15, which has a circumferential constriction 37 at the foot, which as shown in FIG 14b illustrated with the lowermost ring portion 111 of the foldable container 2 of the disposable baby bottle 101 forms a snap and / or clamp connection.
