Total Claims: 18
Claim 1
Independent Claim
192 words
A laundry finishing treatment agent for use in a mechanical laundry drier comprising a paste of at least one effective substance selected from the group consisting of: (1) textile fabric softeners, (2) textile antistatic agents, (3) mixtures of (1) and (2), (4) mixtures of (1) and (2) or both with a disinfectant agent, (5) mixtures of (1) or (2) or both with a laundry odorant, and (6) mixtures of (1) or (2) or both with a disinfectant agent and a laundry odorant, said at least one effective substance being present in an amount sufficient to treat the average laundry processed in said mechanical laundry drier and being mixed with water containing from 0 to 5% by weight of an organic solvent to give said paste, contained in an article of film material having a pillow-like form with one side impermeable to said paste of said effective substance and the other side being a plastic film having a plurality of slits therein of such dimensions, that at room temperature and in the absence of pressure on said article, said slits are substantially closed and obstruct the issuance of said paste from said article.
Claim 2
Dependent Claim
192 words
A laundry finishing treatment agent for use in a mechanical laundry drier comprising a paste of at least one effective substance selected from the group consisting of: (1) textile fabric softeners, (2) textile antistatic agents, (3) mixtures of (1) and (2), (4) mixtures of (1) and (2) or both with a disinfectant agent, (5) mixtures of (1) or (2) or both with a laundry odorant, and (6) mixtures of (1) or (2) or both with a disinfectant agent and a laundry odorant, said at least one effective substance being present in an amount sufficient to treat the average laundry processed in said mechanical laundry drier and being mixed with water containing from 0 to 5% by weight of an organic solvent to give said paste, contained in an article of film material having a pillow-like form with one side impermeable to said paste of said effective substance and the other side being a plastic film having a plurality of slits therein of such dimensions, that at room temperature and in the absence of pressure on said article, said slits are substantially closed and obstruct the issuance of said paste from said article.
