  "description_excerpt": "The present invention relates to a lavatory bowl rim-block comprising: a) at least one container; b) a dispensing means; and c) a fragrance delivery component. The lavatory bowl rim-block herein provides excellent fragrance delivery performance.\n\nA great variety of ways to clean lavatory bowls, such as toilet bowls, has been described in the art. One particular way of cleaning lavatory bowls, such as toilet bowls, are so called rim-blocks. Indeed, rim-blocks are devices that dispense liquid or dissolved solid compositions into a lavatory bowl from under the rim of said bowl. Such rim-blocks are usually attached by various means, such as hooks and the like, to the rim of the lavatory bowl. Rim-blocks dispensing at least one liquid composition into the lavatory bowl, so called “liquid rim-blocks”, are preferred over rim-blocks dispensing a dissolved solid composition. This is due to the fact that firstly, solid rim-blocks tend to exhibit a far greater variation in the amount of product dispensed into the flush during their lifetime. It has been observed that towards the end of the solid rim-block lifetime, the solid composition therein tends to dramatically reduce in size and also in surface area open to the flush water thereby limiting the amount of dispensed/dissolved product. Secondly, the solid rim-block can become highly unsightly during use. Thirdly, the air freshening capability of solid rim-blocks tends to be inferior as compared to liquid rim-blocks as the release of perfume from a solid composition tends to be lower than from a liquid composition.",
