1. Field of the Invention
Embodiments of the invention relate generally to containers for use with liquid dispensers and dispensing systems and more particularly to containers including one or more integrated openings or dip tube guides.
2. State of the Art
Liquid dispensers come in all shapes and sizes and are used for dispensing a variety of liquids. Dispensers and dispensing devices used in the laundry care markets are typically large bottles having a gravity fed valve or a pour spout. Such dispensing devices are often cumbersome and difficult to use due to the size of the bottle and forces required to either pour or dispense the product from the dispensing device. As a result, there is a demand for dispensing devices which offer alternatives to the current devices. There is also a demand for devices which allow a user to operate a dispenser with one hand.
In addition, may liquid dispensers employ the use of a dip tube to transport fluid or product from within a container to a pump system so that the fluid or product may be removed from the interior of the container. In many instances, a dip tube may be cut, shaped, or deformed such that the dip tube is unable to evacuate all of a product from a container. For example, in some containers, low points in the bottom of the container may hold or retain fluid such that the dip tube may not be capable of reaching the fluid for evacuation. In other instances, a user may tip a liquid dispenser such that fluid moves to the front or back of a container, out of the reach of a dip tube. This may result in a loss of prime or inability to pump all of the fluid from a container.
In an effort to alleviate problems with dip tubes, various solutions have been adopted. For instance, U.S. Pat. No. 5,279,450 proposes the use of a partition within a bottle to direct a dip tube to the front of the bottle for evacuation. While use of such a system may be beneficial, the location of the partition with respect to the opening in the bottle may complicate the filling process and attachment of a pump system to such bottle. Similarly, U.S. Pat. No. 5,875,940 discloses a dip tube guide integrated into a container such that the dip tube guide allows a dip tube to be positioned for maximum extraction of a product from a bottle. However, the positioning of the dip tube guide complicates filling and placement of the dip tube and pump system onto a bottle. U.S. Pat. No. 6,059,152 also discloses a dip tube guide.
While various solutions and configurations for guiding a dip tube have been proposed, there remains a need for a solution which allows easy filling, assembly of a pump system to the bottle or container, and ease of use for a user.
According to certain embodiments of the invention, a dispensing device may include a pump system having a large, angled spout allowing the downward dispensing of a product into a wash basin or other delivery area. The dispensing device may also include a bottle or container handle having an angle on an interior of the bottle or container such that a dip tube used with the pump system may be forced into a particular portion or location within the bottle or container. The dispensing device may also include a wide, ergonomic actuator which may be actuated by the palm of a hand or a thumb as a user grips a bottle or container to which a pump system is attached and to which the actuator is in communication for actuating the pump system.
According to other embodiments of the invention, a dispensing device may include a pump system mounted on a bottle or other container such as a pouch. The pump system may include an integrated actuator and handle wherein a leaf-spring or other integrated spring facilitates movement of the actuator with respect to the handle. The integrated handle and actuator may include an integrated connector capable of attaching to a bottle or other container through mechanisms such as a screw closure or a bayonet type closure. In other embodiments, a connector may be paired with the integrated handle and actuator to connect it to a bottle or container.
According to certain embodiments of the invention, a container to which a pump system may be attached may include one or more dip tube guides formed in the container. In some embodiments, the one or more dip tube guides may be formed as openings through the container such that the dip tube guide may also serve as a handle or grip to facilitate transport or use of a dispensing device.
In still other embodiments of the invention, a dip tube guide integrated with a container may be positioned in such a manner to promote the most efficient placement of a dip tube in the container for operation. In some embodiments, the container may also include a front or rear edge that is convex or is shaped to receive an end of a dip tube as it is directed by the dip tube guide.

In some embodiments of the invention, the output of the pump system 200 may also be tailored or customized to provide a desired output relative to the actuation stroke length between the handle 222 and actuator 220. For example, in certain applications, it may be desirable to customize a pump capacity and stroke length to provide an output of up to 100 mL or more of product.
A dispensing device 100 according to still other embodiments of the invention is illustrated in
Dispensing devices 100 according to various embodiments of the invention may be used with liquid products. In some embodiments, a dispensing device 100 may be customized to be used with a laundry product such as laundry detergent. The pump system 200 may be configured to dispense a particular dosage of liquid as desired and the spout 210 configuration and actuator 220 configuration may be customized for the user or for the application for which the dispensing device 100 is to be used.
A container according to various embodiments of the invention is illustrated in
According to various embodiments of the invention, the opening 310 may define a sloped interior wall 312 within the container 300 against which a dip tube will interact upon insertion into the container 300. The sloped interior wall 312 may be sloped, shaped, or designed to position a dip tube in a desired location within the container 300.
According to various embodiments of the invention, an opening 310 in a container 300 may define a bottom portion of the sloped interior wall 312 aligned a certain distance from the center line of a container 300. For example, as illustrated in
In some embodiments of the invention, the distance “Dh” may be between about 0.0 cm to about 8 cm or more. The distance “Dh” may be customized to position a dip tube 290 as desired.
In various embodiments of the invention, the distance “Dv” may be between about 0.0 cm and about 7.6 cm or more. In certain embodiments, a distance “Dv” of about 7.6 cm may be preferred.
According to various embodiments of the invention, the positioning of the sloped interior wall 312 in front of the center line and to a rear of the center line may facilitate proper placement of a dip tube within the container 300. For instance, if on a filling line a dip tube 290 is inserted into the container mouth as a pump system 200 is assembled to the container 300 or attached to a connector 320, the dip tube 290 may be inserted at an angle. As the dip tube 290 is inserted, the positioning of the interior sloped wall 312 behind the center line of the container 300 may facilitate the positioning of the dip tube 290 by guiding the dip tube to a front portion of the container 300. In addition, positioning of a sloped interior wall 312 near the upper end of the container 300—or near the mouth of the container—may help ensure that the dip tube 290 is properly guided, preventing instances where the dip tube may be directed rearward of the sloped interior wall 312.
