Abstract

An injection-moulded plastic child's chamber pot includes a basin part (1) whose wall merges with a seating and supporting part (2) at the top thereof. The front wall part (7) of the basin part (1) slopes obliquely upwards and rearwards in the position of use of the pot. A bottom edge region of an outer wall part (3), formed integrally with the basin part (1) and the seating and supporting part (2) and extending downwardly beneath the underside of the basin part (1), forms a bottom support surface (4) via which the pot is intended to rest on a supporting surface. All pot surfaces define a release angle in relation to the parting direction (5) of two tool halves which form the injection-moulding tool in which the pot is produced and which have a parting plane which coincides with the plane of the support surface (4) and slopes in relation to the normal (16) to the parting direction (5) at an angle corresponding to the angle of inclination of the front wall part (7) plus the release angle of said front wall part.

Description

CHAMBER POT FOR CHILDREN
The present invention relates to an injection-moulded child's plastic chamber-pot comprising a basin part whose wall is curved outwardly in an upper region of said basin part and merges with a seating and supporting part on which a child is intended to sit, wherein the basin part and the seating and supporting part are formed integrally with one another, and wherein the front wall part of the basin part slopes obliquely upwards and rearwards when the pot is in use
Chamber-pots of the aforedescribed kind, see for instance GB Patent Specification No. 646443, reduce in a favourable manner the risk of urine splashes as a child urinates in the pot. However, the inclined front wall part, and therewith the inclination of the whole of the basin, has hitherto caused difficulties, both with respect to manufacture and with respect to use, this latter because the bottom of the basin is moved forwards in relation to the user as a result of the inclined front wall part, therewith increasing the tendency of the pot to tip backwards.
The object of the present invention is to provide a novel and improved chamber-pot construction in which the aforesaid difficulties are eliminated at least to a substantial degree.
To this end, there is proposed a child's chamber-pot of the aforedescribed kind wherein a bottom edge region of an outer wall part formed integrally with the basin part and the seating and supporting part and extending downwardly there¬ from to a location beneath the underside of the basin part forms a bottom support surface via which the pot is intended to rest on a pot supporting surface, wherein all surfaces of the pot define a release angle relative to the parting direction of two tool halves which form the injection- moulding tool with which the pot is produced and which tool halves have a parting plane which coincides with the plane of the support surface and is inclined relative to the normal to the parting direction at an angle which corresponds to the angle of inclination of the front wall part plus the release angle of said front wall part.
In addition to reducing the risk of splashing and also the risk of the pot tipping in use, the arrangement also enables the chamber-pot to be injection moulded in a rational and inexpensive manner.
Further features of the invention and advantages afforded thereby will be apparent respectively from the depending Claims and from the following description of an exemplifying, non-limiting embodiment of the invention illustrated in the accompanying drawings.
Fig. 1 is a side view of an inventive child's chamber-pot. Fig. 2 is a perspective view of the pot shown in Fig. 1, as seen obliquely from above. Fig. 3 is a perspective view of the pot shown in Fig. 1, as seen obliquely from beneath. Fig. 4 is a schematic vertical longitudinal section view of a child's chamber-pot which coincides essentially with the pot shown in Figs. 1-3. Fig. 5 is a vertical longitudinal section view of the pot shown in Fig. 4 and shows the pot as it would be orientated in an injection-moulding tool with verti¬ cal movement of two moulding tool halves and an inclined parting plane between said tool halves. Fig. 6 is a sectional view corresponding to Fig. 1 and illustrates schematically an injection-moulding tool with the tool halves partially separated.
Shown in the drawings is a child's chamber-pot which is comprised of an inner basin or bowl part 1 wherein an upper region of the wall is curved outwardly and merges with a seating and supporting part 2 on which the child sits. Extending from the seating and supporting part is an outer wall part 3 which is intended to rest on a supporting surface, such as a floor (not shown), through the medium of a bottom support surface 4 which is comprised of one or more parts. The pot is comprised of a plastic material, for instance an appropriate thermoplastic material. The basin part 1, the seating and supporting part 2 and the outer wall part 3 are formed integrally with one another by means of an injection-moulding process effected with the aid of an injection-moulding tool shown in Fig. 6. Accordingly, all of the pot surfaces exhibit a release angle in relation to a tool parting direction indicated by a chain line 5 in Figs. 4 and 5, so as to enable the tool and the pot to be parted from one another subsequent to manufacture of the pot in the tool. This release angle will preferably be at least about 2-4°, which is a normal angle in the manufacturing technique concerned. The rear part of the wall part 3 of the pot illustrated in Figs. 1-3 includes a recess 6, as will best be seen from Fig. 3. The pot shown in Figs. 4 and 5 lacks this recess, but is similar to the pot shown in Figs. 1-3 in other respects.
The front wall part 7 and parts of the seating and supporting part 2 and the wall part 3 adjoining said wall part 7 have a greater height than the remainder of the basin wall, so as to reduce the risk of splashing when a child urinates in the pot. The pot is also elevated in the rear region 8 of the pot, to provide better support and seating comfort. In the illustrated embodiment, the bottom of the outer wall part 3 includes outwardly angled parts 9, against which the feet of a child sitting on the pot are intended to rest, whereas the undersides of said angled parts 9 form part of the flat support surface 4. The pot is suitably configured so that several pots can be stacked on top of one another, wherein the stacking direction coincides with the parting direction 5. In order to further reduce the risk of splashing, the pot is constructed so that the front wall part 7 of the basin part 1 slopes obliquely upwards and rearwards, as is best seen from Fig. 4. In order to enable the pot to be injection- moulded in a rational manner, all pot surfaces define a release angle in relation to the parting direction 5, which is therewith inclined obliquely upwards and rearwards in relation to the plane of the support surface. The angle α at which the parting direction 5 is inclined relative to the normal with the plane of the support surface (see Fig. 4) may conveniently lie within an angular range of 15-20" , wherein the wall part 7 will thus slope at an angle of from 11.5- 16.5* with a release angle of 3.5".
Fig. 5 illustrates the pot as it would be orientated in an injection-moulding tool in which the two tool halves move vertically, namely with the plane of the support surface 4 extending parallel with the parting plane (not shown) of the tool halves and being inclined to the horizontal plane at an angle corresponding to the angle at which the parting direction is inclined to the normal with the plane of the support surface.
The injection-moulding tool illustrated in Fig. '6 includes two tool halves 10, 11 of which the upper tool half shown in the Figure is provided with a mould recess or hollow 12 which extends up from a flat mould-half undersurface or parting plane 13, whereas the bottom tool half includes a patrix 15 which projects up from a flat upper surface or parting plane 14 of the mould half and which, when the planes 13 and 14 are in mutual abutment, defines together with the mould recess
12 a mould cavity which corresponds to the pot illustrated in Figs. 4 and 5. The parting planes I3 14 of the partially separated tool halves 10, 11 in Fig. 6 are inclined relative to the normal 16 to the parting direction 5 at an angle α which corresponds to the angle of inclination of the wall part 7 plus the release angle of said wall part. The invention is not restricted to the illustrated and described embodiment of the invention and can be implemented in any desired manner within the scope of the inventive concept defined in the following Claims.
