A unitary package for use in the washing and in the conditioning treatment of fabrics in a laundering operation. There is provided a packet in which a multi-layer plug-like laminate is contained in and is bonded within a cup-like water-insoluble and water-impermeable receptacle having an open top. The laminate presents an exposed upper surface to the wash water in the tub of a washing machine. Only after the materials (for example, detergents) in the top layer of the laminate have dissolved and dispersed does the washing water reach to solubilize the second layer containing the fabric conditioner (for example, a fabric softener). Thus, the article of the invention ensures the simple and highly reliable manner time-spaced sequential incorporation of two different functional agents into a fabric washing system, even though the agents are added simultaneously.

A cartridge for use in fixing an anchor bolt that encludes a fluidtight constructed casing having therein a first fluidtight chamber and a second fluidtight chamber separated from the first chamber, the first chamber containing a resin composed mainly of an ester of an epoxy resin with an organic acid comprising acrylic acid, methacrylic acid or a mixture thereof, the second chamber containing a curing agent for the resin. By the use of such a cartridge in fixing an anchor bolt to a base, there can be attained a quick fixation of the anchor bolt to the base, a high adhesive strength between the anchor bolt and the base, and a high chemical resistance of the cured resin, with little or no lowering of the adhesive strength for an prolonged period of time.

A reactive composition for preparing synthetic resin bodies used in destructible multible-chamber cartridges and a process for anchoring a fastening element to the fastening base by introducing the destruction multiple-chamber cartridges containing the components of a curable adhesive in a drilling in the fastening base. When the fastening element is driven into the hole, the cartridge is destroyed, the synthetic resin components are mixed and harden forming a synthetic resin body. The reactive compound contains between 18 and 25 parts by weight of a pre-activated resin component composed of (A) between 3 and 60 parts by weight of a vinylester epoxy resin, (B) between 28 and 45 parts by weight of one or several ethylenically unsaturated monomeric compounds and (C) between 63 and 3 parts by weight of an unsaturated polyester and if necessary (D) between 10 and 0.1 part by weight of epoxy resin, between 0.4 and 1.2 parts by weight of hardeners and between 40 and 55 parts by weight of fillers.

A process for anchoring a fastener in a base comprising introducing a bore hole in the base a destructible multiple chamber cartridge containing a reactive set for producing a synthetic resin body. The reactive set contains 3-60 parts by weight of a vinyl ester epoxy resin, 28-45 parts by weight of styrene and/or methyl methacrylate, 63-3 parts by weight of an unsaturated polyester resin which is not an ester of a polyepoxide with an ethylenically unsaturated monocarboxylic acid, 10-0.1 parts by weight of an epoxy resin which is not an ester of a polyepoxide with an ethylenically unsaturated monocarboxylic acid, 0.4-1.2 parts by weight of an organic peroxide hardener component, 40-55 parts by weight filler, accelerators, and polymerization inhibitors. The organic peroxide and resin components are in separate chambers. The cartridge is driven into the borehole so that the cartridge is destroyed and the organic peroxide is mixed with the resin components whereby the resin is cured.

An arrangement for mounting an object to a support structure has a mounting element insertable into a mounting hole of the support structure, a flexible container arranged to accommodate an adhesive substance and to be inserted into the mounting hole prior to the mounting element, and an abutment member arranged to abut against an outer face of the support structure and provided with the slot. When the flexible container inserted in the mounting hole is pulled out from the latter and through the slot of the abutment member the adhesive substance is squeezed from the container into the mounting hole so as to anchor the mounting element insertable into the hole.
