This subject matter concerns a dispensing system for a fluid in general, and more particularly a disposable inverted dispensing system for dispensing shampoo or other liquid materials (such as soap or conditioner, or gel or lotion of any type) for use in a shower.
The manufacture and sale of hair care and personal hygiene products constitutes an expansive market. As can be seen in almost any household, shampoo, conditioners, liquid soaps, and other materials represent a large portion of this market. Conventionally, such products are sold in plastic containers which stand upright with a capping device on top through which the fluid, for example, shampoo, conditioner, liquid soap, or other lotions is dispensed. The designs of such containers create several different drawbacks and problems from storage to dispensing. Such plastic containers litter the bathroom shower area of many households creating unsightly clutter. Often, the containers are not readily accessible within the shower area which can lead to the spilling of the container's content. Such clutter, inaccessibility and possible spills can create safety hazards within the shower area, as well as create waste and other disadvantages.
The upright containers also create a dispensing issue due to the configuration of the container in which it is contained and/or the potentially viscous nature of the content being dispensed. The nature of these containers requires the user to perform several steps to dispense the contents of the container. The user typically must pick up the container, invert it and usually squeeze it by applying the user's own pressure on multiple sides of the container to extract the fluid of the container. Further, with the dispensing opening of these containers on the upper end of the container when it is in a stored position, the fluid settles in the bottom of the container prior to use. The more the fluid in the container is used, the longer the distance the fluid must travel with less momentum due to the decrease in the mass of the fluid after each use, and the greater the effort and time required to dispense what fluid remains in the container. Often, the user must shake or otherwise manipulate the container to obtain sufficient fluid from the container.
Other devices and containers have tried to address these problems of the upright containers with varying degrees of success, but all have their own distinct disadvantages. Hanger mechanisms can be attached to upright containers or can hold the upright containers to allow them to be hung upside down on the shower rod or the neck of the showerhead, thereby removing the containers from the floor of the shower and allowing the contents of the containers to settle at the dispensing zone of the container. However, these hanger mechanisms require the user to spend time attaching the hanger mechanism to the container. Some require a hanger to be screwed into the container, creating the opportunity for inadvertent discharge of the fluid. Others require the container to be inserted into a holding mechanism which is then tightened around the container. After the content is dispensed from the container, the holding mechanism is then loosened and the container has to be removed from the hanger mechanism requiring more time consumption.
Also, such hanger mechanisms impede the shower curtain when hung on the shower curtain rod or crowd the neck of the showerhead which has become an often-used location to otherwise hang personal care items. Further, the user still must grab the container on multiple sides and squeeze to dispense the contents.
Permanent soap dispensers as seen in many public restrooms may tend to alleviate certain aspects of clutter, but the user has the burden of filling the dispenser on a periodic basis. For these permanent dispensers, containers of shampoo, conditioner, liquid soap, or other liquid material must be purchased in a store and then the contents of these containers must be transferred into the permanent dispensers. The transfer of such fluid is time consuming and, if care is not taken, creates an opportunity to spill (i.e., waste) the fluid, which in many instances may be rather expensive, particularly for “premium” products such as designer hair care formulas. Further, permanent soap dispensers are affixed to a shower wall in such a manner that, upon removal, lasting marks are left on the wall where the dispenser had been attached.
A need still exists for a dispensing system for shampoos, conditioners, liquid soaps or other consumable personal care fluids that does not add to the clutter around a shower area, is easily accessible in the shower, and decreases the possibility of spillage. A need also exists for the dispensing system to be easily assembled and disassembled to allow for the quick set up (i.e. installation) and disposal of the dispensing system, while still permitting the user to dispense the shampoo, conditioner, soap, or other liquid in a well facilitated fashion without having to shake or manipulate any part of the dispensing system.
