Definitions

  • the present invention relates to applicator attachments for spray cans, and particularly to spray cans including hair-care products such as hair-coloring agents and compositions.
  • a range of hair-care products, treatments and medicaments are available in spray cans, including aerosol spray cans.
  • An example of such a hair-care product is a hair-coloring composition.
  • Spraying products on the hair can be a quick and efficient way to disperse the product over areas of a user’s head, but it comes with drawbacks: for example, an undesirable effect of spraying a hair-coloring composition on the head can be that the spray also finds its way to the user’s scalp and not just to the hair. Another undesirable effect is that some parts of the spray can land on the clothes of the use.
  • an applicator that can protect clothing and/or scalp from errant parts of the spray can be useful. However, simply protecting the scalp from stray droplets can also mean covering hair roots.
  • an applicator In the case of applying a hair-coloring composition, it can be desirable for an applicator to protect the scalp while exposing the hair roots. Simple applicators have been proposed in conjunction with specially designed cans that work together with the applicators. However, there is a need for an applicator that can work with a wide range of commercially available spray cans - for example, aerosol spray cans having a crimped valve cup and an actuator disposed within the valve cup. Many‘high- end’ products are provided in aerosol spray cans having a large actuator button occupying most of the valve cup, leaving only the crimp ring exposed. The actuator buttons are likely to have extended, turret-like nozzles for concentrating the spray and commercially differentiating the product. Thus, there is a need for an applicator that can be installed on a wide range of commercially available spray cans with these features, and that can be easily attached to, and detached from, such cans even those having large actuator buttons with nozzle extensions.

  • such cans may have extended spray nozzles, or tubes extending from nozzle outlets, so as to narrow the angle of distribution of the mist, or aerosol droplets, expelled at the nozzle outlet by actuation of the valve.
