A container for distributing doses of a treatment fluid to a mass of water in a toilet tank which has a level which falls and rises upon slushing of the toilet tank comprises a fluid chamber at the top, a neck at the bottom, and a dosing device mounted in the neck. The fluid chamber contains the treatment fluid and a first mass of air above the treatment fluid, and has a single opening therein. The neck points downwardly into the toilet tank for alternate immersion and removal from the mass of w...

A toggle-action dispensing closure for a container is provided for manipulation between a closed, non-dispensing orientation and an open, dispensing orientation. The closure includes an actuator pivotally mounted along a tilting axis on a body secured to the container. The actuator is tiltable by applying force to the actuator on one side of the tilting axis so as to move the actuator from a non-dispensing position to a dispensing position. The actuator includes a flange having an engagable surf...

The invention contemplates a plastic bottle or container for the storage and selective dispensing of fluent material, such as liquid adhesive, through a dispensing opening at the end of an outwardly projecting neck. Interfitting cap and neck parts establish and assure sealing when the container is closed. The cap includes a central projecting stem which achieves a sealing interference fit with the opening, and the skirt of the cap is relied upon to engage and secure the cap to the base of the ne...

Hindered amines substituted on the N-atom with an --O--E--OH moiety are particularly effective in stabilizing polyolefin and automotive coating compositions against the deleterious effects of oxidative, thermal and actinic radiation where the presence of the OH group on the compounds adds important properties not attainable by the use of normal --O--E moieties.

The present invention relates to novel UV stabilizers of the formula (I) ##STR1## where the substituents are as defined in the description. These compounds are highly suitable for stabilizing organic material, such as plastics, surface coatings, paints and oils, against the action of light, radiation, oxygen and heat.

Disclosed is a process for the preparation of hindered amine light stabilizers by reacting (a) an alkyl substituted-4-hydroxypiperidine with (b) a dicarboxylic acid ester, in the presence of a catalyst system comprising a basic inorganic compound and a polar aprotic organic compound.

A multi-cavity dispensing container is provided for the co-extrusion of at least two flowable materials. The container includes a refill cartridge and a reusable base. The cartridge contains a pair of separate parallel cylinders within which are carried the flowable materials. At a lower end of each cylinder is a piston head. The lower surface of the piston head is configured as a hollow recess. The reusable base is formed with a pair of separate parallel piston support posts. These posts are ch...

Compounds containing a 2,2,6,6-tetramethylpiperidinyl group and a method of making them. The compounds are effective for the protection of organic polymers against degradation due to light and ultraviolet radiation.

Mixtures of esters of polyalkylpiperidine derivatives, of the formulae I and II ##STR1## in which the proportions of I to II are 95 to 70% by weight and 5 to 30% by weight, are obtained by reacting about 2 mols of a piperidine of the formula III ##STR2## with 0.9 to 1.3 mols of a diester of the formula IV ##STR3## in the melt at between 100.degree. and 145.degree. C., in the presence of an alkali metal amide as a catalyst. The mixtures of esters thus obtained are very suitable as light stabilize...

Compounds which contain in their molecule both a hydroquinone monoether or resorcinol monoether radical and a polyalkylpiperidine radical are effective stabilizers for photographic dyes and their intermediates. In particular, they act as stabilizers against damage by light.
