Multi Compartment Container Cap
A multi-compartment container cap comprising a hollow tubular body having a dividing wall forming a proximal compartment located at a proximal end of the hollow tubular body and a distal compartment located at the distal end of the hollow tubular body. The proximal end of the hollow tubular body is adapted to be releasably attached to a container body while the distal compartment comprises a separate compartment for the storage and dispensing of a composition which can be selected to be complementary to any composition store within the container cap.
The present invention relates generally to the field of removable caps for bottles and containers. More specifically, the present invention relates to a convenient and easy to use article which allows two or more products to be stored in the same container in separate compartments.
BACKGROUND OF THE INVENTIONContainer caps having more than one function are known. For example, many container caps provided on conventional laundry detergent bottles provide the dual functions of releasably sealing the container and providing a dosing feature to allow consumers to measure a predetermined volume of the laundry detergent composition for use. Dosing caps are commercially available in a variety of products, including in containers for liquid or granular laundry detergents and fabric softeners. Examples of dosing caps are available in U.S. Pat. No. 2,985,343 to Mask; U.S. Pat. No. 4,892,126 to Bucherer et al.; U.S. Pat. No. 5,662,249 to Grosse; U.S. Pat. No. 5,855,302 to Fisscher et al.; U.S. Pat. No. 5,865,331 to Jacobs et al.; U.S. Pat. No. 6,422,426 to Robins, III et al.; and U.S. Patent Publ. No. 2001/0030165 A1 to Jacobs et al.
In addition, multi-compartment containers are known. See, e.g., U.S. Pat. No. 2,899,096 to Henchert et al. These multi-compartment containers have many different purported uses. One category of multi-compartment containers uses the separate compartments to keep different component ingredients separate during storage but allows for mixing prior to use. Examples of these multi-compartment containers are described in U.S. Pat. No. 5,255,812 to Hsu et al.; and U.S. Pat. No. 5,954,213 to Gerhart et al. Another category of multi-compartment containers are designed to provide a composition reservoir in a first compartment and a composition dispensing mechanism in a second compartment. The composition dispensing mechanism extracts the composition from the first compartment and dispenses the extracted composition. Examples of these types of multi-compartment containers are described in U.S. Pat. No. 2,553,302 to Keskitalo; U.S. Pat. No. 4,636,328 to Flynn et al.; U.S. Pat. No. 5,188,472 to Sgro; and U.S. Pat. No. 7,066,674 to Gueret.
Although container designers and manufacturers have reported many different types of dosing caps and multi-compartment containers, there remains a need for a container cap which can provide the multiple functions of conventional container caps, as well as creating a multi-compartment container for storing and /or packaging a complementary product. The complementary product can be used with the composition stored within the container or can be used in a stand alone application. As such, there remains a need for a new container cap which provides the functionality of a conventional container cap, such as protecting the contents of the container from undesired exposure to the environment and dosing, while providing multi-compartment storage capabilities. Further, the new container cap should be user friendly and simple to manufacture.
SUMMARY OF THE INVENTIONOne aspect of the present invention provides for a multi-compartment container cap comprising: a hollow tubular body comprising: a proximal end; a distal end; an axial dimension extending through said hollow tubular body from said proximal end to said distal end; and a dividing wall positioned within said hollow tubular body, said dividing wall separating said hollow tubular body into a proximal compartment and a distal compartment, wherein said axial dimension is transverse to said dividing wall, wherein said proximal compartment comprises a proximal opening at said proximal end, and wherein said distal compartment comprises a distal opening at said distal end.
Another aspect of the present invention provides for a kit comprising one or more of a multi-compartment container cap comprising: a hollow tubular body comprising: a proximal end; a distal end; an axial dimension extending through said hollow tubular body from said proximal end to said distal end; and a dividing wall positioned within said hollow tubular body, said dividing wall separating said hollow tubular body into a proximal compartment and a distal compartment, wherein said axial dimension is transverse to said dividing wall, wherein said proximal compartment comprises a proximal opening at said proximal end, and wherein said distal compartment comprises a distal opening at said distal end; and a container body comprising a reservoir and a neck operably connected to said reservoir, wherein said proximal compartment of said one or more of said multi-compartment container caps are adapted to be removably attached to said neck.
As defined herein, hermetic refer to seals between container components (such as the lid and multi-compartment container cap and the multi-compartment container cap and container body) which provide at least a degree of resistance to moisture migration through the seal, at least equal to that of the container and hollow tubular body materials. Such seals may also provide resistance to migration of gases at least equal to that of the container body and lid materials
As defined herein, hollow tubular body means a conical, cylindrical, squared or other multi-sided shape which can have the same or varying shape and/or cross sectional area along its height. Non-limiting examples of suitable container cap shapes are provided in U.S. Pat. Nos. D390,466 and D390,462 both to Mao; U.S. Pat. No. D389,740 to Toleman; U.S. Pat. No. D189,059 to Vanderhyde; and U.S. Pat. No. D306,265 to Jeo.
As defined herein, substantially perpendicular to a planar surface means that upon determining a normal vector to said planar surface, any line intersecting said planar surface forms an angle of between about 0° and about 15° from said normal vector. Where the surface does not form a plane, the normal vector is determined by ascertaining the center point of said surface, then taking the normal vector of the tangential plane to the center point of said surface.
As defined herein, substantially water tight means that no appreciable amount of liquid water will is visibly observed to pass through a sealed compartment under ambient environmental conditions.
