- the prefabricated cup bottom is inserted from below into the sleeve (made according to the invention). Before glue is applied. After this Inserting the cup bottom, this is preferably crimped and pressed to form a permanent, firm and tight connection with the sleeve.
- the angle W of the lateral surface, which surrounds the cup 20 approximately corresponds to the angle W of the slots 12 which have been punched out of the first paper web 11 (see Fig. IA).
- the slots 12 are parallel to the longitudinal direction L of the first paper web 11, i.e., the first paper web 11 is elongated.
- the angle W is here equal to O.
- Fig. 4 is purely schematically indicated that the length LS of the tab 17 may be shorter than the length LK of the side edge. This may be the case, for example, if a cup bottom is to be used in the lower region of the paper cup 20, which has a small distance to the lower edge. In Fig. 3 and in Fig. 4, the position of such a cup bottom is indicated by a dotted line 21. In this case, the tab 17 does not have to be guided all the way to the lower edge 19.2 along the side edge 16, since it does not need any edge protection below the bottom.
- the adhesive used for lamination may also be used to create the edge protector and shape the paper cup 20. It can also be used here but another adhesive.
- Fig. 8 is indicated in a highly schematized magnification, where the adhesive 22 can be applied to allow the forming of the edge protection and the forming of the paper cup 20.
- the first web 11 and / or the second web 13 can be printed in an intermediate step, preferably a recyclable dye is used for printing.
- the webs can be provided as sheets and / or rolls.
- the first method steps are carried out to then to stock the semi-finished product in the condition shown in Fig. 1C or to send it to a customer.
- the last steps of the process are carried out, for example using a conventional cupping machine.
- the inventive method can be easily integrated into a machine manufacturing plant.
- the paper cups 20 may have a rolled edge.
- the rolled edge is made at the upper edge 19.1.
- the present invention can also be applied to other packaging 20.
- first web 11 dissolves upon prolonged contact with water or at least easily compostable. Due to the then missing first web 11, the bonding agent layer and the second web 13 can then also be dissolved and / or biodegraded.
- the barrier or resistance properties of the second web 13 exist at least for a defined period of use.
- the second web 13 may be single or multi-layered.
