摘要:
A container for a free-flowing product, in particular typographic correction fluid, includes a tubular neck with an application aperture with a valve closure for the controlled application of metered quantities of the fluid to a substrate. The container remains, over an extended period, perfectly capable not only of applying spots of fluid precisely at a given point but also of applying the fluid over large areas. This is achieved by fitting the container with a second tubular neck with a second aperture and fitted with a removable closure cap with an integral applicator brush. Both tubular necks are disposed in the upper part of the container in such a way that the far end of the tubular neck with the application aperture projects out beyond the cap when the cap is in place over the second aperture.

摘要:
A self-supporting and self-adhesive molded article is described having a glass transition temperature of less than 10° C. and containing a binder and an aliphatic or cyoaliphatic nonionic surfactant. The binder may contain at least one addition polymer or addition copolymer. The article is redetachable from the material surfaces to which it may be adhered. Thus, the article may be attached, detached and reattached to a wall or cabinet surface and may have paper or other light weight, decorative material attached, detached and reattached to it. The detachment and reattachment process maybe repeated numerous times, particularly with intervening cleaning of the surface of the self-supporting and self-adhesive molded article.
