阅读说明：本技术 包含两种不同组合物的球形马桶块 (Spherical toilet block comprising two different compositions ) 是由 T·霍尔德鲍姆 T·泽格勒 T·许米泽卡 于 2019-06-28 设计创作，主要内容包括：本发明涉及一种固体马桶块,其包括至少一种第一组合物和第二组合物,通过非同心共挤出步骤获得,并且涉及生产该马桶块的方法和涉及包含该马桶块的设备。(The present invention relates to a solid toilet block comprising at least a first and a second composition, obtained by a non-concentric co-extrusion step, to a process for producing the toilet block and to an apparatus comprising the toilet block.)

1. A solid toilet block (402, 502) having at least a first composition (121, 221, 321, 421, 521) and a second composition (122, 222, 322, 422, 522), wherein the first composition is different from the second composition, and the production of the toilet module comprises a co-extrusion step, wherein the first composition is in spatial contact with one part (110a, 220a, 320a) of a channel sidewall and the second composition is in spatial contact with another part (110b, 220b, 320b) of the sidewall, wherein the extrudate is formed into a spherical shape (502) by the forming step, and thus the toilet block has a substantially spherical geometry.

2. The toilet block of the preceding claim, wherein the first composition has at least a first active and the second composition has at least a second active, wherein the first and second actives are different from each other.

3. The toilet block of the preceding claim, wherein the first active is a first dye and the second active is a second dye.

4. A toilet block according to claim 2 or 3, wherein the first active is a first perfume and the second active is a second perfume.

5. A toilet block according to any preceding claim, wherein the production of the toilet block comprises a forming step following the co-extrusion step.

6. A toilet block as claimed in any preceding claim, wherein the extrudate is cut into smaller units (330).

7. A toilet block as claimed in any preceding claim, wherein the channel is substantially cylindrical.

8. A toilet block as claimed in any preceding claim, wherein the portion of the channel side wall contacted by the first composition and the portion of the channel side wall contacted by the second composition have substantially equal surface areas.

9. Device comprising at least one toilet block according to any of the preceding claims, wherein the at least one toilet block is present in a chamber of the device, wherein the device can be connected to the rim of a toilet.

10. The device of the preceding claim, wherein the device has at least two, preferably at least three, and more preferably at least four toilet blocks.

11. A method of producing a solid toilet block, the method comprising:

a coextrusion step, wherein at least a first composition and a second composition are brought together in a channel of an extruder head before exiting through a profile die, such that the first composition is in spatial contact with a portion of the side wall of the channel and the second composition is in spatial contact with another portion of the side wall, and wherein the process further comprises:

a cutting step, wherein the extrudate is cut into smaller units by the cutting step, and wherein the method further comprises:

a forming step, wherein the extrudate is formed into a spherical shape by the forming step, and thus the toilet block has a substantially spherical geometry.

12. The method according to claim 11, wherein the forming step and the cutting step are performed simultaneously.
