Definitions

  • a detergent dispensing cap for pre-treating a stained fabric A detergent dispensing cap for pre-treating a stained fabric.
  • Treating stained garments continues to be an aspect of laundering that could be improved.
  • the consumer merely washes with a detergent advocated as having the ability to treat stains.
  • Such an approach tends to work satisfactorily if the stains are light and not greasy. If the stains are heavy, the stains might not be removed because the chemical ingredients of detergent are diluted in the wash and are not concentrated at the stain. This can leave the consumer dissatisfied when at the end of the wash cycle she sees that the stains are still visible.
  • the prospects for successful stain treatment after washing are limited, particularly if the failure is not detected until after drying the stained garment.
  • liquid detergents can be effective when used to pre-treat stains by locally applying a small quantity of detergent to the stained portion of the garment.
  • Many consumers do not use liquid detergents to pre-treat stains because they are unaware that such a practice can be successfully used to treat stains and the practice can be messy and cumbersome. Thus, many consumers use specialized stain treatment aids.
  • Stain treatment aids may be applied to the stain in liquid form by spraying or squirting the stain treatment aid directly on the stain or using a wipe impregnated with a stain treatment aid to scrub a stain.
  • Some stain treatment aids include a motorized brush or scrubbing implement to assist with treating the stain in the fabric.
  • the typical consumer experience with presently available approaches for treating stains in the home is cumbersome.
  • the consumer first has to remember to purchase the detergent, the stain treatment aid, and any accompanying devices, or replacement devices.
  • the consumer then stores all of these items near the washing machine.
  • the consumer must remember to identify and treat stains prior to the stained garment being placed in the washing machine.
  • the consumer must then locate the stain treatment aid and manipulate the packaging or device to apply the stain treatment aid to the stain.
  • the consumer stores the stain treatment aid, frequently in an unsightly gathering of laundry products nearby the washing machine. Consumers often rinse their hands after this step to avoid the greasy feeling of common stain treatment aids and to avoid transferring the stain treatment aid to other surfaces, washing machine controls, and detergent packaging.
  • the consumer opens the laundry detergent, measures out the appropriate dose, and delivers the dose of detergent to the washing machine.
  • the consumer stores the laundry detergent. This multistep process is a less than desirable consumer experience, particularly given all the other demands on the consumer's time and mental focus.
  • a cap for dispensing a detergent composition can comprise a base having a base interior and a base exterior opposing the base interior, the base interior having a periphery.
  • the cap can comprise a vessel wall having an interior surface and an exterior surface opposing the interior surface, the vessel wall extending from the periphery to a rim.
  • the interior surface and the base interior can define a pour volume, the base interior forming a closed end of the pour volume.
  • the cap can be releasably attachable by a pressure fitting to a container and detachable there from, the container containing a detergent composition.
  • the cap can further comprise a plurality of first surface irregularities at a location selected from the group consisting of on the rim, the exterior surface, the base exterior, and combinations thereof.

  • the weir 160 can be aligned with the first surface irregularities 150.
  • Such an embodiment can be practical because as the user of the cap 10 dispenses the detergent composition 300 over the weir 160 to pre-treat the stain, the consumer will be holding the cap 10 in a position such that the user does not have to reposition her hand to rub the first surface irregularities 150 against the stain. Further, as the consumer observes the pour, she is likely to see the first surface irregularities 150, which will provide her with a visual cue to use the first surface irregularities 150 to scrub the stain.
  • the user is able to see the first surface irregularities 150 when pouring of a unit dose is initiated. This can be practical as a reminder to the consumer to pre-treat stains if she sees the surface irregularities 150 as she pours the unit dose into the wash basin prior to pre-treating stains.
