Abstract: A dissolvable effervescent toilet deodorizer includes a combination of citric acid, sodium bicarbonate, and essential oils. In one method of use, a user would drop the dissolvable effervescent toilet deodorizer into the toilet bowl just prior to using the toilet. Once dropped into the toilet bowl, the dissolvable effervescent deodorizer begins to dissolve and effervesce. As a result of the effervescence, the dissolution occurs more rapidly and also disperses the deodorizer/scent into the toilet water and air to more effectively neutralize and/or prevent malodors.

Abstract: The present invention concerns a paint roller comprising a frame having a handle portion and a shaft, a sleeve support rotatably mounted on the shaft for receiving a roller sleeve, and a locking mechanism moveable between a first position in which a paint roller sleeve can be slid over the said support and a second position in which a part of the mechanism is urged against the inside wall of a roller sleeve mounted on the said support in use, whereby to lock the roller sleeve to the frame. The locking mechanism preferably comprises at least one locking element, preferably a resilient element, and first and second axially movable parts which are movable relative to each other to cause the locking element to be urged outwards against the inside wall of a roller sleeve mounted on the support.
