    专利说明:

    The invention relates to a holding device arranged on the underside of an eating container such as a plate for cups of different sizes with the common feature of a protruding upper edge.
    Thanks to the invention, a full loaded with food plate including an inserted cup can be held and transported with one hand, whereby the other hand is kept free for activities such as feeding food to the mouth.
    The need for one-handed holding of food and drink arises especially when standing meals or snacks as part of breaks for meals, entertainment and a variety of themed gatherings where no suitable storage space for a drink desired to be consumed with the meal are available.
    The prior art includes several examples which also attempt to meet this need by attaching a holding device which enables a cup to be attached to the underside of a eating container such as a plate. US2014319157 and US2007264167 are simple examples of the functional principle that is most likely used in devices comparable to the invention. The protruding cup edge is gripped under by rigid flanges, which are attached to or sunk into the base of the plate as parts of a slide-in rail and allow the cup to be placed in a hanging position. As set out in US5240136 and US5292028, brackets of this type can also be designed as sections of a slide-in rail or as short, flanged retaining elements and do not necessarily have to run parallel, as can be seen from those embodiments in which they are designed as rounded sections, including lined up (or staggered, see USD866264S) Combinations of differently spaced pairs, which are intended for cups of different sizes. The same functional principle is also used for cup holders that are designed as incomplete circles (US5292028, FIG. 6 and US2008257895) or where the slide-in rail merges into an essentially semicircular closure (US2016120342 and US5176283).
    The examples mentioned and similar known designs have several disadvantages that limit or destroy their suitability for practical use. It should be noted here that the practical suitability within the scope of the present invention includes the basic requirement that only devices are taken into account that are suitable for cups of different sizes and designs, according to the conditions prevailing in everyday use of the invention. This excludes a priori devices that are based on the production of ensembles and thus only adequately fulfill their purpose with specially made drinking vessels.
    But even if the devices taken into account here expressly or implicitly claim that they are suitable for commercially available cups of different sizes and types, they do so in at least two respects only to a very limited extent: If, according to the above functional principle, the protruding The edge of the cup rests on essentially rigidly constructed flanges, the horizontal distance between the opposite flanges on the one hand and the vertical distance between the supporting surfaces of the flanges and the upwardly limiting surface (e.g. in the form of the plate bottom) are decisive for stable and liquid-tight fixation . It is true that the deformability of the cup rim and cup wall inherent in all cups in use allows a certain tolerance with regard to the horizontal distance between the opposing flanges. However, this tolerance varies depending on the design and material of the cup, and if it is exceeded, if the distance is too small, the excessive deformation leads to a buckling of the cup rim or to breaks in the cup rim and / or the cup wall; on the other hand, if the distance is too large, the cup cannot be attached at all or only with the risk of an unstable connection. The latter is especially the case when the deformed cup has a low restoring force in the held position and its protruding edge at most still has a relatively small profile. If the vertical distance between the supporting surfaces of the flanges and the limiting upper surface, for example the plate base, is also only slightly too large in relation to the thickness of the protruding cup rim, the cup will no longer be sealed and the cup contents may be tilted or jerky Movement sloshes out or drips down, while if the distance is increasingly too great there is also the risk that the fixation becomes unstable due to shaking; If, on the other hand, the distance between the flanges and the base of the plate is too small, it is not even possible to insert the cup or the cup rim will jam.
    In addition, there is typically the problem with the known devices that the cup cannot be introduced with sufficient accuracy without lifting the plate.
    In addition, known devices have the disadvantage that the stackability of the plates provided with them is impaired, since their flange structures reduce the density and strength of the stack. In addition, there is a risk that the flange structures will get caught in unevenness or textiles if the plates are handled on surfaces in the cupless state.
    Finally, the state of the art also calls for a simpler and more contemporary solution with regard to the production effort and the consumption of resources.
    The invention is therefore based on the object of providing a holding device that allows one-handed holding and transporting a plate in combination with a commercially available cup and thereby combines the advantages that the cup easily and reliably on the underside of the plate in a stable position can be pushed and just as easily removed again, that the cup contents are covered splash and drip-proof, that the device is suitable for a variety of common cups of very different sizes and designs, that it is as simple and resource-saving as possible to manufacture and that a plate provided with it allows unrestricted handling and stacking.
    The invention solves the problem by the features of the holding device and the plate equipped with it, which are recorded in the following description and in the claims.
    The core of the holding device consists of variable blanks for a varying range of cup sizes, with the blanks, if they are provided, for example, with an adhesive layer and protective film, are already marketable products and open up sales options. In the following, however, preferred embodiments of the invention are described, which are designed as a coordinable combination of blank and plate.
    The made of a rigid flat material such as cardboard blank for the holding device preferably largely coincides with the plate base, with the exception of the recess for the conical insertion slot and the protruding, i.e. the plate base protruding corners at the open end of the insertion slot. The blank is connected to the plate base, for example by gluing, except for the side strips of the insertion slot, which are to be dimensioned depending on the material, in the following referred to as guide strips. When the cup is inserted, the unglued guide strips reach under its protruding upper edge, which means that the cup can be pushed into a fixed position while it is simultaneously pushed upwards by the guide strips that are urging to be reset and covered with a sufficiently liquid-tight cover by the bottom of the plate. Thanks to the conical guide strips and their restoring force, when the cup is pushed in, essentially horizontal and vertical forces act simultaneously on the cup rim and cup wall, which gives the holding device according to the invention unprecedented functional and stability advantages and expands the structural scope for the device, not least in connection with the type and nature of the materials that can be used.
    The end portions of the guide strips protruding beyond the bottom of the plate are advantageously designed so that they expand the conical shape of the insertion slot at its open end in a funnel-like manner and thereby facilitate the insertion of the cup, which is preferably additionally facilitated by the fact that viewing windows are provided in the edge of the plate which at least partially reveal the end sections of the guide strips protruding beyond the edge of the plate in order to make pivoting away and lifting of the plate largely unnecessary. As an alternative to the viewing windows or in addition to them, the invention provides at least one cutout on the edge of the plate as a further possibility in order to be able to locate the end sections of the guide strips more easily when looking at the plate from above.
    Further advantages and features of the invention are explained in more detail in the following description with reference to the drawings, wherein the listed individual features can be combined as desired and configured differently in shape and dimensions from the description without going beyond the scope of the invention.
    The drawings are not to be understood as true-to-scale representations. 1: An oblique view from below onto a plate provided with the holding device according to the invention, FIG. 2 an oblique view from above onto the plate according to FIG. 4 shows a schematic partial view of a longitudinal section of the cup rim and holding device in the state of use, with a basic illustration of the position-fixing forces, FIG. 5 shows a diagram according to FIG. 4, but with the cup rim designed as a flat rim, FIG. 6 shows a perspective partial view of a plate with a cutout edge 7 shows a plan view of the underside of a plate equipped according to the invention with edge cutouts and viewing windows matched to two insertion slots, FIG. 8 shows a three-piece blank for the holding device according to the invention with three insertion slots.
    1 and 2 show a preferred embodiment of a plate 2 equipped with the holding device 1 according to the invention. At least one, but preferably a plurality of viewing windows 4 are provided in a plate rim 3, which are shaped and arranged so that a person who holds the plate 2 in an upright position with an angled arm, is able to move important parts of the holding device 1 so far into its field of vision by a slight change in the angle of view through the viewing window 4 that it does not use the plate 2 for attaching and inserting the cup 5 Have to turn away and lift every time. In particular, the viewing windows 4 are arranged for this purpose in such a way that, depending on the plate shape, they are more or less perpendicular above the two outer corners of the insertion slot 7 protruding from the plate base 6. These corners represent the end sections 8 of the two conically running guide strips 9 of the insertion slot 7. The blank of the holding device 1 preferably largely coincides with the plate base 6 except for the recess for the insertion slot 7 and the end sections 8. The area of the blank of the holding device 1 shown in dotted lines is connected to the plate base 6, for example by gluing, in contrast to the adjoining guide strips 9, which only rest on the plate base 6. Grooves 11 are provided along the border between the guide strips 9 and the adhesive surface 19, shown in dotted lines, depending on the flexural rigidity of the cut material. The grooves 11 extend at least along part of the guide strips 9 towards their end sections 8 in order to favor the bending of the guide strips 9 when the cup 5 is inserted. The end sections 8 are preferably designed in such a way that they widen the conical shape of the insertion slot at its open end somewhat in the shape of a funnel in order to make it easier to grasp the cup 5 and in particular the cup rim 10, especially with regard to differently sized upper cup radii.
    At the inner end of the guide strips 9 an incision 12 is provided if the blank and the plate base have an average to high flexural strength or thickness, otherwise a need-based bending of the guide strips 9 is not guaranteed and the cup when inserted experiences too much resistance. The incisions 12 extend over the width of the guide strips 9 up to the bond line and thus the grooves 11, if present. For gluing the blank along the incisions 12, small, unglued safety gaps are provided in order not to hinder the bending of the guide strips 9 under any circumstances.
    In the case of low flexural rigidity of the blank material used, it is at most appropriate to dispense with the incisions 12 and to leave the cross section 13 of the insertion slot 7 indicated by dashed lines in the approximate width of the guide strips 9 unglued.
    Optionally designed additional recesses 14 in the plate rim 3 offer themselves as a possibility to provide visual indications of the arrangement, longitudinal axis and - especially if several insertion slots 7 are present - the relative size of the respective insertion slot 7.
    Fig. 3 illustrates how the grasping and reaching under the cup rim 10 is facilitated by the fact that between the plate vault 15 and the end portions 8 there are two aisle-like spaces 16, into which the cup rim 10 can be easily and effortlessly smuggled.
    Fig. 4 is a schematic illustration of the horizontal and vertical forces (Fh, Fv) that act when inserting the cup 5 and ensure its secure fixation, the only crucial requirement on the cup 5 is a protruding upper edge, like almost all cups in the scope of the invention.
    5 illustrates how the position-fixing forces Fh, Fv act equally reliably in the case of a cup 5 provided with a flat rim 17, in particular also a plastic cup. Plastic cups often pose a problem for known holding devices insofar as their wall and / or their upper edge is either too easily deformable due to the use of soft plastic, or they have a low deformation tolerance and tend to break due to the use of rather brittle plastic. Thanks to its conical, flexible guide strips 9, the invention also permits reliable fixation of cups 5 of different sizes in these cases, while the restoring force of the guide strips 9 ensures a sufficiently liquid-tight cover even in the case of flat edges 17.
    Fig. 6 shows in a partial view how, as an alternative to the viewing windows 4, one or more edge cutouts 18 in the plate rim 3 create the possibility of moving the end sections 8 more easily into view when using the holding device 1.
    Provided that the plate size is adequate, the holding device 1 according to the invention enables the range of compatible cups to be expanded considerably by equipping the blank with several insertion slots 7 of different sizes.
    7 shows the holding device 1 in a preferred two-piece embodiment with two insertion slots 7 which are arranged on a substantially square plate 2. The insertion slots 7 come together from opposite directions in the area of the center of the plate, the guide strips 9 of the two insertion slots 7 opening into projections 21 at their inner end, in order to in particular a small cup 5 when it is inserted into the smaller insertion slot 7 before it may slip through into the opposite one larger slot 7 to preserve. If a material of very low flexural strength or thickness is selected for the blank, it can be advantageous to connect the two blank halves to one another, for example in a shape similar to the crosspiece 20 shown in dashed lines Blank and thus for the plate base 6. This applies to all embodiments according to the invention of blanks with several insertion slots 7, which is why a space-saving design with insertion slots 7 open at their inner end is recommended.
    7 further illustrates how viewing windows 4 and edge cutouts 18 can be combined in order to additionally facilitate the view of the end sections 8 of the guide strips 9. Further recesses 14 in the plate rim 3 provide additional information on the different sizes of the insertion slots through their positioning.
    Fig. 8 shows a schematically illustrated arrangement for a preferred embodiment of the holding device with three insertion slots 7. The dashed ellipses represent the fully inserted cup 5 in different sizes. Significantly, the multi-part blank in this case does not have any grooves 11, although these can also be applied in this arrangement if the material selected for the blank and the plate 2 is appropriate. However, as can be inferred from the arrangement shown, blanks with multiple insertion slots for common plate sizes have smaller adhesive surfaces 19, which generally reduces the retention for the guide strips 9 considerably and their bending does not have to be additionally promoted by grooves 11.
