Definitions

  • the present invention relates to a process of dosing a detergent composition.
  • Wash processes such as laundry wash processes, involve the step of dosing the detergent from a container into the washing machine or wash liquor.
  • Closure of the lids aims to minimise water ingress into the containers which can affect the physical stability of the internal detergent. Such ingress is particularly problematic in high humidity environments such as those found in the vicinity of the wash operation (such as laundry or dish washing). Closure of lids also aims to reduce spillage or removal of the detergent from the container when it is not intended or otherwise desirable, for example, if the container were to fall or become upside down or fall on its side. Therefore, such containers are manufactured with locking means to ensure the lid remains closed when not in use.
  • the dosing operation involves firstly disengaging the locking means and opening the lid of the container.
  • the operation of disengaging the locking means can be difficult for consumers and for example result in the container simply being pushed away from the consumer rather than the lock disengaging and/or the consumer finds the whole operation awkward or uncomfortable to the fingers and hand.
  • manufacturers have relocated the latch component of the lock to the top of the container wall, with a corresponding lid component remaining in the lid.
  • the process of dosing when using such locking means can be difficult for consumers to disengage as they required the latch component to be pushed away from the user whilst simultaneously lifting the lid. This might result in the container simply being pushed away from the consumer rather than the lock disengaging and/or the consumer found the whole operation awkward or uncomfortable to the fingers and hand.
  • the dosing process may require pulling the lid component over a latch component, which has the risk of plastically deforming the lid component due to accidental excessive pressure being used and so the lid component not being able to re-engage again.
  • the process according to the present invention overcame this problem.
  • the process requires the user to operate a 'pinching motion' to open the container and access the detergent. Such a motion is more comfortable and intuitive for the human hand and also allows for the consumer to simultaneously lift the lid. Also, it reduces the risk of accidental plastic deformation of the lid component.
  • the present invention is to a method of dosing a detergent composition comprising the steps of;
  • Obtaining a consumer product comprising a container and a detergent composition, wherein the container comprises;
  • a lid and at least one wall wherein the at least one wall comprises an inner surface and an outer surface and at least one locking means, wherein to open the lid the locking means needs to be manually disengaged by the user using a pinching motion, wherein the locking means comprises a latch component and a lid component and the pinching motion moves the latch component from a first position to a second position, wherein the second position is closer to the outer surface than the first position;
  • step d adding the detergent composition from step d to an automated washing apparatus, a manual washing operation or a mixture thereof; f. closing the lid and applying sufficient force to the lid to ensure the locking means reengages.
  • FIG. 1 discloses a consumer product which can be used with the process of the present invention.
  • FIG. 2 discloses a schematic showing the pinching motion disengaging the locking means.
  • FIG. 3 discloses a water-soluble unit dose article according to the present invention.
  • FIG. 4 discloses a latch component according to the present invention
  • the present invention is to a method of dosing a detergent composition.
  • the detergent composition is described in more detail below.
  • Dosing a detergent composition herein means the process of taking a detergent composition from a first location, preferably a storage location, and adding it to water to create a wash liquor. Alternatively, it may be added to an automatic washing machine such as an automatic laundry washing machine or automatic dishwashing machine.
  • the method comprises the steps of;
  • Obtaining a consumer product comprising a container and a detergent.
  • the consumer product can be sold 'as is', in other words the consumer product is the item that the consumer picks up from the shelf.
  • the consumer product could be housed as one unit of a multi-component product.
  • more than one consumer product could be housed within an outer package and the multiple packaged consumer products sold together in a single purchase.
  • the consumer product may comprise aesthetic elements, for example shrink sleeves or labels attached to the container.
  • the container may be coloured or printed with aesthetic elements or informative print such as usage instructions.
  • a lid and at least one wall wherein the at least one wall comprises an inner surface and an outer surface and at least one locking means, wherein to open the lid the locking means needs to be manually disengaged by the user using a pinching motion, wherein the locking means comprises a latch component and a lid component and the pinching motion moves the latch component from a first position to a second position, wherein the second position is closer to the outer surface than the first position;
  • a 'pinching motion' Preferably this is achieved using a thumb and finger to perform the pinching motion to disengage the locking means.
  • the 'thumb and finger' pinching motion is where a finger is brought towards the thumb as if the two were to touch.
  • This motion of finger and thumb allows the finger and thumb to achieve a firm grip on an object and efficiently exert force upon it, e.g. force upon a locking means to disengage it.
  • this is achieving using a finger and the thumb of the same hand.
  • a finger from one hand and thumb from the other hand may be used.
  • achieving a pinching motion is not limited to a finger/thumb motion.
  • the user could use two fingers, preferably a finger on a first hand and a finger on a second hand.
  • an exemplary locking means comprises an element on the container and an element on the lid. When the element on the container and the element on the lid are engaged, then the lid is locked in place. However, disengaging the lid element from the container element, unlocks the lid and allows it to be opened.
  • the container comprises a wall and the locking means comprises a first part on the lid and a second part on the container wall.
  • the lid may automatically move to an open position, e.g. via a spring.
  • the lid is attached to the container via a hinge and in step c the lid is pivoted via the hinge away from the rest of the container.

  • closure of the lid will be a reverse operation of the opening of the lid.
  • the user simply use his/her hand to push the lid towards the container and into a closed position.
  • re-engagement of the locking means is accompanied by an audible indicator, more preferably a clicking noise. The audible indicator ensures the user is aware the locking means have re-engaged and serves as a reminder to re-engage the locking means.
