Description

FIELD OF THE INVENTION

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. In particular, the present invention relates to 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.

BACKGROUND OF THE INVENTION

A variety of packages, including dispensing packages or containers, have been developed for household products, personal care products, and other products. Currently, there are several 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. In the present invention, 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.

Currently, most closures complete the geometry of the container, thereby requiring the size of the closure to be proportional to the geometry of the container. In one embodiment of the present invention, 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. Another benefit of minimizing closure size is that the 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. When the container is in its inverted orientation, 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.

SUMMARY OF THE INVENTION

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.

DETAILED DESCRIPTION OF THE INVENTION

According to the present invention a closure (1) for an outlet opening of a container comprises 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 the closure. The first component connects the second component with the container. It enables the sealing mechanism for the container and first component and sealing between the first and second component. Non-limiting examples of a sealing mechanism include a plug seal, a telescoping seal, a membrane seal, a crab claw seal, a silicone membrane seal, spin or ultrasonic welding, glue adhesive and mixtures thereof. In an embodiment of the present invention, the sealing mechanism for the container and first component is a plug seal (9) and the sealing between the first and second component is a telescoping seal (8). A telescoping seal (8) may enable dynamic sealing between the first and second component. The telescoping seal maintains the seal as the user operates/actuates the closure.

The first component can comprise a male/female thread mechanism to enable closure operation and female ramps (20) to provide stability to the second component comprising male ribs (21) during closure operation. In a further embodiment, a thread mechanism may comprise mechanical female/male thread, designed in a helical path, to enable vertical movement of the second component relative to the first component.

Also, the first component (3) comprises an anti-rotating female feature (22) to prevent free movement of the closure as well as the counter part for an audible mechanism (23). An anti-rotating feature can prevent the first component from spinning freely relative to a container neck opening. There is also a second anti-rotating feature which is female mechanism (14) in one embodiment, and may be male mechanism (15) in another embodiment, between the first and second component such as an interlocking joint feature which may be a mechanical interlocking joint. An audible mechanism may communicate to the user when the closure is either closed or open. In a further embodiment of the present invention, the first component may comprise a snap ring(s) (24) which enables the first component to be securely attached to the neck of the container.

In an embodiment of the present invention, a second component comprises a dispensing orifice wherein the second component is, threadingly engaged with the first component. The second component may comprise features that contribute to the user interface. Such component comprises the color/shape differentiation as well as the tactile features (13) and ergonomic intuitive design components. It also has the counter part mechanisms for the audible, telescoping seal, dispensing orifice, female/male thread mechanism, ramps/tracks stability features and anti rotating features.

In an embodiment in the present invention, a dispensing orifice (5) 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 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 (26). Most of the features within the first component are located at or below the plane of the container opening outlet (25). This enables the features to be placed at locations that are typically considered dead space. This allows for a design that has significantly less height than typical closures and as a result significant weight reduction of the overall closure is achieved. This will not only enable significant manufacturing cost reduction but, will also enable sustainability improvement by developing a closure that can be manufactured in half or less time (due to less energy consumption) and less part weight than average closures.

In an embodiment of the present invention, wherein the first component comprises one or more elements or one or more mechanical features being in a specific juxtaposition enabling a small height/low profile/a narrow profile regardless of the diameter of the container opening.

In an embodiment of the present invention, the height or distance of the specific juxtaposition may stay constant regardless of the size of the diameter of container opening. For example, the low profile needed for a small container opening may stay constant for a larger container opening.

In an embodiment of the present invention, the first component (3) may comprise one or more sealing regions, such as a plug seal (9) and telescoping seal (8) located on the top of the neck or extending beyond the top plane of the neck or top plane/surface of the neck and inside the neck of the container or it is located within the height of the neck or below the neck of the container enabling a small height or low profile or a narrow profile or same plane for mechanical features/elements of the first component.

In a further embodiment of the present invention, the first component (3) may comprise one or more elements located at or below a plane defined by a top region/area of a neck outlet of the container enabling a small height or low profile or a narrow profile or same plane for all of the mechanical features/elements of the first component.

In an embodiment of the present invention, a closure (1) for an outlet opening of a container is provided comprising a first component (3) which assembles onto an outlet opening (26) and provides a seal for an outlet opening said first component is threadingly engaged to a second component (4) of said closure; a second component (4) comprising a dispensing orifice (5) of the second component (4), the second component (4), threadingly engaged with the first component (3); a dispensing orifice (5) positioned directly adjacent to the open portion of the container body; wherein the second component (4) will engage with the first component (3) when the second component is moved relative to the first component (3) to enable operation of the orifice and wherein a full assembly of the first component (3) and the second component (4) comprises at least one material, and in a further embodiment, at least two materials.

In one embodiment of the present invention, in order to allow a user to reveal the dispensing orifice (5) of a package, a closure (1) may be designed with various different types of movements. A closure (1) may move by rotational movement along an axis, diagonal movement, and horizontal movement, vertical movement, a twist movement, elevate movement, slide movement, and mixtures thereof to reveal a dispensing orifice.

To achieve the above directional movement, in an embodiment of the present invention, the following mechanical features may be designed in the closure; female/male thread interface, a flow channel that may have a telescoping mechanism, a cylindrical, an elliptical, a square, or triangular shape; pivot points, swivel hinge type mechanisms and mixtures thereof.

In one embodiment of the present invention, the first component (3) comprises a male thread (6) to engage with said second component (4) and the second component (4) comprises female thread (7) which is a counterpart feature component of the closure. In a further embodiment of the present invention, the first component (3) comprises a female component to engage with said second component (4) and the second component (4) comprises male component which is a counterpart feature component of the closure. In a further component the first component may comprise a combination of female and male component and the second component may comprise a combination of female and male components as well.

The female (7) and male (6) threads allows the two components to stay together as one component. The female (7) and male threads (6) also enable the closure movement from a lower position to an elevated position. This allows the user to reveal the dispensing orifice (5) and hence dispense a fluid.

In an embodiment of the present invention, the second component (4) is moved in a concentrical movement, linear movement, axial movement, radial movement, co-radial movement, eccentrical movement, spiral movement and mixtures around the first component (3).

The dispensing orifice (5) may be revealed in different ways. For example; in a rotate/twist to open closure (1), the dispensing orifice (5) is opened via a female/male thread interaction where the first component (3) rotates/spins within it's axis of rotation, concentrically to the second component (4).

In a further embodiment of the present invention, the closure is integrated with a body of a container (FIG. 7 and FIG. 8). By having a closure as small as functionally possible; it may provide a centered or an offset of the closure to one side and have the container shoulder flush to the closure top surface. It also provides full integration of the closure within the shoulders (10) of a container (1), and in a further embodiment within the shoulders (10) of a container (1).

In an embodiment of the present invention, the closure (1) is integrated with a body of a container, as shown in FIGS. 5 and 8, wherein geometry of the closure acts in completing the silhouette of the body of the container. In a further embodiment, in an inverted orientation a recessed closure allows the use of a container shoulder to add stability vs. requiring a full size closure on top of a container.

In a further embodiment of the present invention, closure geometry provides a surface for optimal leverage to operate a closure. A closure (1) is operated by a single hand of a user or by two hands of a user. A closure may have features with enhanced ergonomics such as handles, levers, alternative materials, textures, specific shaped contours, and combinations thereof. These features are strategically positioned to enable ease of use with either wet or dry hands. For example, in an embodiment of the present invention, in a twist/rotate to open closure (1) that uses female/male threads, the further away the lever or point of opening is from the axis of rotation, the easier the opening of the closure will be for the same area of applied pressure. In other words, in such an embodiment, the further the distance from the axis of rotation is, the less force will be required by the consumer to open the closure for a specific torque. The closure design could either have an enhanced shroud design for ease of use or ergonomically incorporated levers (11) or an egonomically incorporated lever (29).

In an embodiment of the present invention, a closure (1) may comprise a mechanism that suspends one component relative to the other component to ensure a closure remains closed or open. As part of a twist/rotate motion to open a closure, the first and/or second component may have bumps or protrusions (12) in either a female thread (7) or a male thread (6) that will prevent a closure to close while opened or to open while closed. When the male thread (6) passes over the protrusions (12) or bump, the closure will lock in place and thus not allowing the second component (4) to open or close by itself.

In a further embodiment of the invention, a closure comprises a first component (3) which comprises an orienting mechanism which enables a specific orientation of the first component (3) relative to an outlet opening of a container. In this embodiment, a closure has either a male mechanism or female mechanism (22), which act as an orienting mechanism, that interacts with the male mechanism (30) or female mechanism (22) of a container to prevent free rotation and enable closure orientation for proper closure operation.

In an embodiment of the present invention, a closure (1) comprises a first component (3) comprising an orienting mechanism which enables a specific orientation of the second component (4) relative to the first component (3). This embodiment comprises a design that takes advantage of a first component female tracks and creates a female/male mechanism configuration with the second component to align and prevent further rotation between the first component (3) and a second component (4). In this embodiment, the female mechanism (14) and male mechanism (15) is designed in an interlocking joint which may allow for a more robust and stable engagement between the first component (3) and the second component (4).

In an embodiment of the present invention, a closure (1) rotates around an axis between an open and a close position.

In a twist/rotate to open closure a second component (4) is rotated around an axis to move the second component (4) relative to a first component (3) between a lower and elevated position, allowing a user to reveal the dispensing orifice (5) of the second component (4).

In a further embodiment of the present invention, a closure (1) comprises tactile features (13) and/or visual features (16) that provide a user with direction on how to operate the closure. The closure (1) will incorporate tactile features (13) and visual features (16) that will cue or communicate to a user to know where to press/push/hold and which direction the force needs to be applied.

In an embodiment of the present invention, a closure comprises an audible sound mechanism. In an embodiment, a closure may have a cantilever feature (17) or a similar mechanical feature that will generate a sound as the user manipulates a closure from an open to a closed position and/or closed to open position. This will communicate to a user when a closure is fully opened and when a closure is fully closed.

In a further embodiment of the present invention, the first component (3) may comprise anchor ribs (27) to provide stability of the second component (4) relative to the first component.

By having anchor ribs (27) in either the first component (3) or second component (4), the integrity of the assembly increases and therefore the more stable the assembly will be. This is because the anchor ribs (27) may limit the side-to-side movement (wobble) of the second component (4) relative to the first component (3).

In a further embodiment of the present invention, the first component (3) may comprise anchor ribs (27) to keep first component (3) and second component (4) intact upon removal of the closure.

By having anchor ribs (27) in either the first component (3) or the second component (4), the integrity of the assembly increases and therefore the more robust the engagement of the assembly will be. This is because the anchor ribs (27) are limiting the side-to-side movement (wobble) of the second component and consequently they increase the retention force of the second component (4) relative to the first component (3). The anchor ribs (27) increase the engagement of the retention feature that enables the second component (4) to stay together with the first component (3). In a further embodiment of the present invention, wherein the first component (3) or the second component (4) may comprises multi stage opening bumps for metered dosing. By having a multistage opening closure, a consumer will be capable of opening the closure at different heights and therefore control the size of the dispensing orifice opening. This will enable the consumers to dispense a preferred amount from the container, which is different from existing closures were a consumer has limited control over the amount that they dispense from their containers. The present invention will enable the consumer to always dose the same exact amount every single time.

By having a multistage opening closure the consumer will be capable of opening the closure at different heights and therefore control the size of the dispensing orifice opening. This will enable the consumers to dispense their preferred amount from the container. Different from today were they have limited control over the amount that they dispense from their containers. The present invention will enable the consumer to always dose the same exact amount every single time.
