Title: Assembly of a cup and a stirring element, as well as a cup and a stirring element intended for such an assembly.
The invention relates to an assembly of a cup and a stirring element, the stirring element and/or the cup being provided with fastening means for fastening the stirring element to the cup.
Such an assembly is known from the European patent application EP-A-0 761 146, wherein the cup is provided with a handle and wherein the stirring element is provided with an opening with which the stirring element can be slid over the handle to thus be attached to the cup.
The present invention contemplates a different solution for providing ah assembly of a cup and a stirring element. To this end, according to the invention, the assembly is characterized in that the fastening means are designed such, that, in a fastened condition, the stirring element assumes a shape which is such that the stirring element in the fastened condition has the function of a handle by which the cup can be lifted. The cup itself, therefore, is not provided with a handle but only obtains a handle after the stirring stick has been connected to the cup in the fastened condition mentioned. This offers, inter alia, the advantage that the cup without stirring stick can be designed so as to be stackable. In particular with disposable cups for use with beverage machines, this offers the great advantage that the cup can be received in existing stack holders.
The fastening means can comprise a flanged edge adjacent a rim of the cup, a first extremity of the stirring element being designed such that it can be attached behind the flanged edge of the cup. The fastening means can then comprise grooves adjacent a lower side of the cup, in which grooves a second extremity of the stirring element is clampingly receivable. It is then preferred that the extremity of the stirring element is hook-shaped, such that it can be hooked behind the flanged edge of the cup.
By receiving the stirring element with the stirring extremity in the grooves adjacent the lower side of the cup and, subsequently, hooking it with the hook-shaped extremity behind the flanged rim of the cup, the stirring element is forced into a bent shape suitable for serving as a handle by which the cup can be lifted. Here, the grooves adjacent the lower side of the cup can be provided both in the bottom wall of the cup and in the circumferential wall.
Preferably, the grooves taper and an extremity of the stirring element cooperating with a respective groove also tapers, so that a clamping reception of the stirring element extremity in the groove is obtained. It is preferred here that the grooves are undercut grooves, such that the stirring element, also in a direction perpendicular to the wall in which the grooves have been provided, cannot be taken out of the groove.
According to an alternative further embodiment of the invention, the fastening means can also comprise a second flanged edge adjacent a lower edge of the cup, a second extremity of the stirring element being shaped such that this can be hooked behind the second flanged edge of the cup. For this second extremity of the stirring element it also holds that a hook-shaped extremity is preferred.
Optionally, also in a second fastened condition, the stirring element can be connected to the cup such, that the stirring element abuts against the circumferential wall of the cup over substantially the entire length, so that the cups with the thus attached stirring elements are stackable. Such an embodiment offers the advantage that the stirring elements are always available when a cup is available. In the second fastened condition, the connection between the stirring element and the cup can then be formed by break-off bridges such as, for instance, plastic film bridges or pre-perforated bridge parts.
According to a further elaboration of the invention, the cup can be manufactured from plastic or from cardboard. The stirring element can be
manufactured from plastic or from a different material such as, for instance, wood or cardboard. Preferably, the entire assembly is of the disposable type.
The invention also relates to a cup as well as a stirring element, evidently intended for an assembly according to the invention. The invention will presently be further elucidated on the basis of three exemplary embodiments, with reference to the drawing.

Fig. 7 shows the hook-shaped extremity of the stirring element in more detail;
Fig. 8 shows a top plan view of the exemplary embodiment shown in Figs. 3 - 7; Fig. 9 shows a cross section along the line IX-IX of Fig. 8;
Fig. 10 shows the detail X of Fig. 9;
Fig. 11 shows a perspective top plan view of a third exemplary embodiment; and
Fig. 12 shows a perspective bottom view of the exemplary embodiment represented in Fig. 11.
The exemplary embodiment represented in Figs. 1 and 2 comprises a cup 1 and a stirring element 2. The cup is provided with a lower and an upper flanged edge 4, 3 respectively. The first extremity 5 of the stirring element 2 is inserted under the upper flanged edge 3, while the second extremity 6 of the stirring element 2 is inserted behind the lower flanged edge 4. In Fig. 1, the stirring element 2 is in a second fastening condition in which it extends substantially entirely along the circumferential wall of the cup 1. In this condition, different cups 1 with stirring element 2 are stackable. To provide the stirring element 2 with the handle function, one of the extremities 5 or 6 is to be displaced relative to the other extremity 6, 5, so that these extremities are substantially in the same vertical plane. Due to the reduced distance between the two extremities 5, 6, the stirring element 2 will bend outwards and obtain a handle-shape by which the assembly of the cup 1 and stirring element 2 can be lifted. This condition is represented in Fig. 2. In Fig. 2, in dotted lines, the stirring element 2 is shown still in the second fastening condition, in which the stirring element 2 abuts against the circumferential wall of the cup 1. The arrow P shows the direction in which the stirring element 2 has been displaced to the first fastening condition in which the stirring element has obtained its handle function. Thus, the assembly can be lifted by the stirring element 2 functioning as a handle. In this exemplary embodiment, the extremities 5, 6 of the stirring element 2 have a flat configuration. However, it is also possible that these extremities have a hook- shape or like shape with which a firm connection between the cup 1 and the stirring element 2 can be obtained. Figs. 3 - 10 show a second, preferred exemplary embodiment of an assembly according to the invention. The fastening means at the lower side of the cup 1 are here formed by tapering, undercut grooves 7 in the bottom wall of the cup 1. The stirring element 2 is provided with a tapering second extremity 8 which is clampingly receivable in the tapering grooves 7. As the grooves 7 are undercut, i.e. that the bottom of the groove 7 is wider than the upper side
of the groove 7 because the groove side walls, viewed from the bottom, incline towards each other, a stirring element extremity 8 inserted therein cannot be taken out of the groove 7 in a direction perpendicular to the bottom wall of the groove 7. The tapered configuration of the groove 7 and the stirring element extremity 8 enables the stirring element extremity 8 to be clampingly received in the groove 7.
Adjacent the rim, the cup 1 is provided with a flanged edge 9. The first extremity of the stirring element 2 has a hook-shaped configuration 10 which is arranged to be hooked under a flanged upper edge 9 of the cup 1. The hook-shaped configuration 10 is clearly visible in Figs. 7 and 10. The manner in which the hook-shaped extremity 10 of the stirring element 2 is hooked behind the flanged edge 9 of the cup 1 appears in particular from Fig. 10. In this exemplary embodiment too, by fitting the stirring element 2, a cup 1 with handle is obtained, allowing the cup 1 to be lifted by the handle. Figs. 11 and 12 show a further exemplary embodiment which is distinguished from the exemplary embodiment of Figs. 3 - 10 in that the tapering, undercut grooves 7 are included in the circumferential wall of the cup 1 instead of in the bottom wall of the cup 1.
The exemplary embodiments shown all involve assemblies in which the cup and the stirring element are manufactured from plastic. However, it is also possible that these parts are manufactured from different materials. For instance, the cup may be manufactured from cardboard or metal and the stirring element may be manufactured from wood, impregnated cardboard or the like. Also, the stirring element 2 may have a somewhat pre-shaped configuration, so that, when fitting it to the cup 1, it easily assumes the shape of a handle. However, it is also possible that the stirring element is simply a substantially straight stirring stick. Further, the stirring element could have a bowl of a spoon, the shape of a groove being arranged for clampingly receiving the bowl of the spoon.
