Description

The invention relates to a chamber pot, in particular for small children, according to the preamble of claim 1.

Chamber pots are preferably used on trips or to bring toddlers the way to the toilet. For example, has become known by the company Baby Björn AG a two-piece chamber pot, which is made by injection molding of plastic. This chamber pot comprises a lower part, which has a footprint for supporting a substrate. At this footprint, a side wall is supported, which merges at an upper end in an edge and an inner receiving area. An upper part, which is formed separately from the lower part and can be lifted for emptying and cleaning of the lower part, comprises a seat surface and a within the Seat arranged cup-shaped shell part. The seat is preferably in one piece in the shell part. On an outer side of the seat, a support edge is provided which carries the seat and is supported on the edge of the lower part. The pot-shaped shell part engages in the receiving area of the lower part.

Such chamber pots are preferably formed bicoloured in order to achieve a pleasing aesthetics. In each case, a color for coloring the plastic is selected for the lower part and for the upper part. These designs no longer meet the ever-increasing design requirements. In addition, with such two-part chamber pots, it can often happen that the upper part slips to the lower part.

The invention is therefore based on the object to propose a chamber pot, which has a pleasing external design and at the same time allows a high level of security in daily use.

This object is achieved by a chamber pot with the features of claim 1. Further advantageous embodiments and further developments are specified in the further claims.

Due to the inventive design of a chamber pot, in which the side wall of the base has a decorative surface produced by an inmold process, depending on the design requirements or the need different surfaces can be created in a simple manner, regardless of the further color scheme of the upper and Bottoms are. To produce such a decorative surface on a side wall, it is necessary for the edge provided on the lower part to be designed as an edge running along the side wall in order to achieve a high quality of the decorative surface on the outer wall. Due to the two-part design of the chamber pot, this peripheral edge can be realized in a simple manner. At the same time a secure arrangement of the upper part to the lower part is made possible by the support edge of the upper part rests on the peripheral edge of the lower part at least partially and this at least partially overlaps. As a result, a secure attachment and positioning of the upper part to the lower part are made possible. At the same time, good load transfer via the seat surface to the footprint can be achieved across the interface between the upper and lower parts. This inventive design of the two-piece chamber pot so the benefits of high design standards and the flexible adaptation to different design requirements as well as high reliability are equally possible.

A preferred embodiment of the chamber pot provides that the upper part has a splash guard section in a front region and a support section opposite in the rear region, the splashguard section and the support section being raised relative to the seat surface and preferably flowing into the seat surface. Preferably, the splash guard portion is formed in height less than the support portion. By such a type of saddle-shaped design of the upper part, a good fit of the seat is achieved with the support surface and at the same time ensured by the splash guard section unintentional Nachaußentreten the urine.

Furthermore, a flattening is preferably provided on a rear side of the support surface on the upper part, which comprises an engagement opening. This allows the top to be handled in an area that is not usually wetted with urine. In addition, the otherwise closed outer shape of the upper part can be taken in a simple manner for emptying the upper part and cleaning the upper part.

A further preferred embodiment of the invention provides at the edge of the lower part, preferably in a front region of the lower part, a latching element, on which a receiving element engages the support edge of the upper part and secures the upper part against lifting from the lower part. Preferably, a locking tab is provided opposite the receiving element on the upper part, which releasably engages the lower part. This arrangement allows a secure fixation of the upper part to the lower part for use. Furthermore, this will be a simple Merging and separating the top and bottom allows. For example, to complete the chamber pot may be provided that initially engages the receiving element of the upper part of the locking element of the lower part, by a pivoting movement about this quasi-formed hinge connection, a rear portion of the upper part is moved toward the lower part. After the support portion of the upper part at least partially rests on the peripheral edge and this at least partially overlaps, the locking tab can be brought to engage the lower part, so that the upper part is secured against lifting from the lower part.

The arranged on the upper part locking tab, which is arranged in a rear region, preferably engages on a recess on the lower part, which is provided on the flattening of the lower part. This allows a simple Verklipsen or locking the Verschiusslasche and good accessibility to release the locking tab be given.

The closure flap is arranged according to a preferred embodiment by a film hinge on the upper part, in particular on a flattening of the upper part. As a result, the chamber pot can only consist of the upper and lower parts, without the need for additional separate parts, so that a secure connection between the upper and lower part is created.

The receiving area provided on the lower part of the chamber pot is preferably recessed in relation to a front side of the peripheral edge, wherein preferably this receiving area is formed by a web section which is perpendicular to the side wall or at an angle deviating therefrom of less than +/- 20 ° to the rectangular orientation is aligned to the outer wall. This arrangement has the advantage that the plastic melt impinges when approaching the side wall quasi right angle or almost at right angles to the side wall and propagates in both directions, which due to the dimensioning of the peripheral edge of this space is immediately filled with plastic, so that the exclusive flow direction of the Plastic melt along the outer wall to the footprint occurs. As a result, a decorative foil provided on the outer wall, which is preferably held by electrostatic charge in the injection mold, is virtually smoothed out and fixed by itself. As a result of the rapid filling of the region for forming the circumferential edge, a holding section for the decorative film is thus formed, which additionally secures the decorative film against displacement or wrinkling within the injection mold.

Furthermore, it is preferably provided that the receiving region extends completely along the circumferential edge and comprises at least one strip-shaped section. As a result, a rectangular or nearly rectangular inflow of the plastic melt to the side wall takes place in the entire region along the selenium edge in order to achieve a high quality of the decorative surface on the side wall.

The receiving area of the lower part preferably has an opening for receiving the shell part on the upper part. This opening allows a large-volume shell part.

The receiving area of the lower part furthermore has a hump-shaped elevation adjacent to the flattening. This hump-shaped increase substantially corresponds to the contour of the support section, which merges into the seat surface on the upper part. Thereby, the chamber pots are stackable, wherein a high support portion can be formed, which is not limited by the distance of the receiving area to the footprint at the bottom of the nesting each other.

Analogously, a hump-shaped elevation is likewise preferably provided in the front region of the receiving region. Thereby, the splash guard section can also be formed with the required height.

A further preferred embodiment of the chamber pot provides that the shell part in the upper part has a bottom, which in the plane of the footprint of the lower part in a fixed to the lower part shell is or that the ground is at least slightly increased compared to the footprint. In the first variant, a load transfer or a support on the ground can additionally take place via the shell part. In the second alternative, there is no transmission of forces of the shell part on the ground. Thus, this shell part can be made smaller in wall thickness.

According to a further advantageous embodiment of the invention, the support edge of the upper part on a continuously encircling shoulder, which at least partially extends with its respective ends in the flattening. As a result, a particularly high rigidity of the upper part is achieved, since the shoulder also extends over a corner region between the supporting edge and the flattening.

Furthermore, the receiving region of the lower part is preferably completely surrounded by the peripheral edge. By this arrangement, a particularly rigid design of the lower part is created. At the same time, a full shoulder can serve to rest the support edge of the upper part.

A further preferred embodiment of the invention provides that the side wall of the lower part and the flattening of the lower part are aligned with the support edge of the upper part and the flattening of the upper part. As a result, a good load transfer can be created. Furthermore, a visually appealing shape is achieved, so that the two-piece chamber pot awakens a visual impression of a cast.

In FIG. 1 is a schematic view of the chamber pot 11 according to the invention. For a more detailed explanation of the chamber pot 11 according to FIG. 1 will be on the FIG. 2 Referring to the chamber pot according to FIG. 1 in a full cross-section shows and on FIG. 4 Reference is made, which shows a two-part chamber pot 11 made of plastic, which is made by injection molding.

The chamber pot 11 comprises a lower part 12 with a footprint 14, on which downwardly oriented and not shown stopper elements can be provided as anti-slip support. The footprint 14 is formed for example as a hat brim. Alternatively, only a narrow web-shaped surface can be provided with enlarged sectors for receiving the stopper elements. The footprint 14 is followed by a side wall 15, which extends to an upper edge 17. By the side wall 15, a contour in the oval bottom part is formed, which includes a slightly conical side wall 15. This oval Shape is only an example. The circumferential side wall 15 of the lower part 12 is interrupted by a flat 18, which is preferably located in a rear portion of the chamber pot 11. In this flattening 18, a recess 19 is provided which extends to near the edge 17. The lower part 12 is made of plastic in an injection molding process. It is preferably provided that the side wall 15 of the lower part 12 has a decorative surface produced by the in-mold method. In this method, preferably before the injection of the plastic melt into the injection mold, the desired decorative film is introduced into the injection mold, which is preferably held by an electrostatic charge in the injection mold. To achieve a high quality of the decorative surface of the edge 17 is formed as a circumferential edge 21, wherein a receiving portion 22 of the lower part 12, which forms a kind of end face for the lower part 12 and is formed as a wall portion, opposite a front side 23 of the edge 21 is recessed , At the same time, this wall portion of the receiving area 22 is aligned at right angles to the side wall 15 or at an angle thereto of less than +/- 20 °. As a result, the molten plastic material can strike the side wall 15 almost frontally during the injection molding process and keeps the decorative film fixed to the injection mold. Subsequently, the free space formed by the edge 21 is quickly filled with plastic melt, so that subsequently flows the flowing plastic melt along the side wall 15 in the direction of the footprint 14. As a result, a simultaneous smoothing of the decorative film takes place. The receiving region 22 or a wall section directly adjoining the edge 21 preferably extends fully and at least in a strip shape along the circumferential surface of the side wall 15, on which a decorative surface is formed by a decorative film.

On the lower part 12, an upper part 26 of the chamber pot 11 can be placed and can be connected to this firm, but releasably. The upper part 26 comprises a seat surface 27, which merges on the outside thereof into a support edge 28. This support edge 28 of the upper part 26 is located, as in the enlarged sectional view in FIG. 3 is shown, at least partially on the end face 23 of the peripheral edge 21 and overlaps this edge 21 at least partially. It is preferably provided that the support edge 28, at least in the region of the side wall 15, completely overlaps the encircling edge 21 and rests on the end face 23. As a result, a stable and rigid two-part embodiment of the chamber pot 11 can be created. At the same time the risk of injury to the edge 21 is reduced by the full overlap. In addition, 26 support ribs 29 may be provided on an inner wall portion of the upper part, which have a distance from the support edge 28, so that lying between the edge 17 of the lower part 12 can engage the upper part 26. The support ribs 29 preferably also rest on the receiving region 22. As a result, an improved fixation of the upper part 26 to the lower part 12 can take place.

Adjacent to an inner side of the support surface 27, a pot-shaped shell part 30 is formed, which extends through a recess 32 in the receiving region 22 therethrough. A bottom 33 of the shell part 30 is preferably located in the plane of the contact surface 14. In a front region of the upper part 26, the seat surface 27 merges into a splash guard section 35, which is raised relative to the seat surface 27. In the rear region of the upper part 12, the seat surface 27 merges into a support section 36 in order to give the infant a secure hold on the chamber pot 11. The support portion 36 is formed in the height preferably larger than the splash guard portion 35. At a rear of the support portion 36, a flat 37 is provided, which merges directly with the flattening 18 of the lower part. In the flattening 37 an engagement opening 38 is provided, so that an easy handling of the upper part 26 is made possible.

In the rear region of the receiving region 22 near the flat 18 on the lower part 12, a hump-shaped elevation 41 is provided, which extends in the direction of the upper part 12 and at least partially immersed within a Stützabschnlttes 36. This allows several chamber pots 11 are stacked to save space, as the Support portion 36 of the lower pot 11 in the elevation 41 of the above-arranged chamber pot 11 engages. At the same time, the shell parts 30 of the superimposed chamber pots 11 engage with each other. In a preferred manner, an elevation 42 may also be provided analogously in a front region, so that when the night pots 11 are stacked on top of one another, the splash guard section 35 can engage in such an elevation 42.

For locking the upper part 26 to the lower part 12, a latching element 43 is preferably integrally formed in the front region on the lower part 12, on which a receiving element 44 integrally formed on the upper part 26 engages. The latching element 43 and the receiving element 44 can also each be manufactured as a separate component and, for example, by a Klips- or locking connection on the upper part 26 and lower part 12 are attached. This receiving element 44 is quasi formed as an undercut to engage the locking element 43, so that the upper part 26 held down to the lower part 12 and in a first phase is still pivotable. Such a position goes for example from the FIGS. 5 and 6 out. In these illustrations, an intermediate step is shown during attachment or removal of the top 26 from the bottom 12. The receiving element 44 of the upper part 36 attacks in any case on the locking element 43 of the lower part 12, so that the upper part 26 to the lower part 12 in the in the FIGS. 5 and 6 is fixed position shown. Subsequently, the upper part 26 can be pivoted to the lower part 12. For complete fixing a closure tab 46 is actuated so that it engages the recess 19 of the flattening 18. For this purpose, the closure tab 46 comprises a detent element or clip element, not shown in greater detail, so that a detachable fixation is provided. For articulated connection of the closure tab 46, a film hinge 47 is formed on the flat 37. Alternatively, further attachment mechanisms or closures may be provided. The latching element 43 and the receiving element 44 can also be arranged reversed on the lower part 12 and upper part 26. The latching element 43 may also be designed as a latching lug or as a cam, which engages in a complementary geometry on the upper part 26 and thereby fixes the upper part 26 to the lower part 12.
