Method for producing washing and cleaning agents in the form of filled moulded bodies II
A process of making detergent tablets by forming a basic tablet cavity, filling the cavity with an appropriate detergent material, and the cavity with a film that forms part of a label wrapping the tablet.
1 . A process for making detergent tablets comprising the steps of:
a) forming a shaped body having at least one cavity;
b) filling the cavity with one or more active substances in liquid, gel, paste, or solid form; and
c) sealing the filled cavity with a film,
wherein the film comprises in whole or in part a label that is applied to the tablet.
2 . The process of claim 1 , wherein the shaped body is formed in step a) by tabletting a particulate premix.
3 . The process of claim 1 , wherein the shaped body is formed in step a) by thermoforming and/or casting and/or injection molding and/or blow molding a water-soluble or water-dispersible polymer or polymer mixture.
4 . The process of claim 1 , wherein an adhesive is used to apply the label to the shaped body.
5 . The process of claim 1 , wherein the shaped body produced in step a) is delivered to the filling step b) on a conveyor belt travelling at a speed of 0.01 to 1 m/s.
6 . The process of claim 5 , wherein the conveyor belt is travelling at a speed of 0.02 to 0.5 m/s.
7 . The process of claim 6 , wherein the conveyor belt is travelling at a speed of 0.03 to 0.3 m/s.
8 . The process of claim 7 , wherein the conveyor belt is travelling at a speed of 0.05 to 0.2 m/s.
9 . The process of claim 1 , wherein a plurality of shaped bodies produced in step a) are arranged on a tray and are subsequently filled b) at the same time and then sealed c) at the same time.
10 . The process of claim 9 , wherein at least four shaped bodies are arranged on the tray.
11 . The process of claim 10 , wherein at least six shaped bodies are arranged on the tray.
12 . The process of claim 11 , wherein at least ten shaped bodies are arranged on the tray.
13 . The process of claim 12 , wherein at least twelve shaped bodies are arranged on the tray.
14 . The process of claim 9 , wherein shaped bodies are filled in b) at a rate of 5 to 30 trays per minute.
15 . The process of claim 14 , wherein shaped bodies are filled in b) at a rate of 10 to 25 trays per minute.
16 . The process of claim 15 , wherein shaped bodies are filled in b) at a rate of 15 to 20 trays per minute.
17 . The process of claim 1 , wherein two or more labels are punched from a larger piece of film at the same time, held by vacuum, and applied to the shaped bodies after application of adhesive to the shaped bodies and/or to the labels.
18 . The process of claim 17 , wherein the adhesive is applied to the shaped body by roller.
19 . The process of claim 17 , wherein the adhesive is applied to the shaped body by casting.
20 . The process of claim 17 , wherein the adhesive is applied to the labels by roller.
