Definitions

• the present invention relates to a closure for an outlet opening of a container comprising a first component which assembles onto an outlet opening and provides a seal for an outlet opening, said first component is threadingly engaged to a second component of said closure; which will engage with the first component when the second component is moved relative to the first component to enable operation of the orifice.
• a first component comprising one or more elements being in a specific juxtaposition enabling a small height and low profile/ a narrow profile for one or more of the elements wherein a seal and the mechanical features supporting the operation of the closure are in the plane or below the plane of the outlet of the container.
• closure designs on store shelves They all vary from Disc/pivot top, push to open, flip top, push and pull, twist to open, as well as a variety of others.
• a current disadvantage of all these closures is that they don't take into consideration the ease of use, audible/tactile signals, intuitiveness, and ergonomic features that delights the consumer.
• designs being developed take into consideration consumer insight. All closures represent one handed operation that demonstrates obviousness in open and close position with integrated locking feature. Also, the present invention will enable upright and inverted use of the package.
• Each closure is holistically designed to deliver intuitive operation; obviousness of being open or closed; ergonomic to operate; and providing all of the sensory (audible, tactile and visual) cues for operation. Further, the present invention expands on consumer insights that drive to efficiency per usage experience.
• the size of the closure is minimized thereby providing several benefits.
• One of the benefits is reducing the weight of the closure to the minimum amount of resin needed to enable the required closure functionality. This is a benefit for the environment as industry currently does not have a well established polypropylene recycling stream. By having a closure that has a reduced weight from the overall package, this allows a container to have improved recyclability. It also reduces the overall costs of the closure including costs associated with resin, processing, tooling, injection mold (IM) press selection, and others.
• IM injection mold
• closure becomes a less focal point of the design making it more inductive to use the same closure for different container designs within one brand and even enable the use of the same closure across different brands/shaped families. This drives optimization and efficiency and in return reduces further costs. This further enables the silhouette of the shape to be scaled proportionally without the use of additional features such as container shoulders and angles to accommodate the closure.
• Another benefit for minimizing the closure size is that it can be integrated in the container shape.
• an integrated design allows the use of the container top surface to add stability vs. requiring a larger closure. This drives scale in the container design and development and therefore is an advantage. It also aids in creating differentiation between the forms (such as shampoo and conditioner), helping consumers identify the product that they are looking for.
• the present invention is directed to a closure for an outlet opening of a container comprising a first component which assembles onto an outlet opening and provides a seal for an outlet opening said first component is threadingly engaged to a second component of said closure; a second component comprising a dispensing orifice of said second component, said second component, threadingly engaged with said first component; a dispensing orifice positioned directly adjacent to the open portion of the container body; wherein the second component will engage with the first component when the second component is moved relative to the first component to enable operation of the orifice and wherein the first component comprises one or more elements/one or more mechanical features being in a specific juxtaposition enabling a small height/ low profile/ a narrow profile for one or more (the majority of) of the mechanical features/elements of the first component wherein the seal and the mechanical features supporting the operation of the closure are in the plane or below the plane of the outlet of the container.
