ABSTRACT:
BACKGROUND OF THE INVENTION
Suspension of a soap bar for air drying has long been a desired objective, as witnessed by the various approaches for positioning the bars above a surface in which wash water can collect. Many soap dishes have upwardly facing tines, drain flutes and ridges, all of which attempt to achieve keeping wet bars from resting in residual water and becoming mushy. Their success in achieving the desired goal has been nominal only. Such dishes require frequent cleaning because it is impossible for wet soap as it softens while dissolving during a washing operation from adhering to the tips of the tines and upper edges of the ridges or flutes. This wastes the bar as it wears, becoming an added cost burden to the user by requiring replacement more frequently than if the bar were able to be suspended in air after use.
One type of soap bar has achieved the air drying objective, that product being known as “Soap-on-a Rope”. A rope is embedded within, i.e., the soap is molded about, the rope. A loop is formed in the rope to enable it to be hung from a hook or other projection. One problem with this product is its cost, however, mainly because it is labor-intensive to produce.
SUMMARY OF THE INVENTION
A method is provided for producing individual personal-sized bars of soap with a water-resistant supporting medium having a hole therein, the medium being integral with each bar for enabling its suspension from a hook for air drying after each use. The preferred method incorporates an intermittent feeding technique of a web of the medium whereby a portion of the medium protrudes beyond one end of a soap bar. An alternative method incorporates a feeding technique resulting in soap bars wherein the medium and the soap material of each bar are the same length. A hole is provided either through the medium alone in the preferred method, or through both the soap and the medium in the alternative method. The method may include the additional step of providing a soap-compatible adhesive to opposite sides of the supporting medium.
A principal object of the invention is to provide a low cost method of continuously producing soap bars with a water-resistant sheet material laminated between opposite sides of the bars and provide a hole through the sheet material to enable individual bars to be suspended in air for drying after use.
Other objects will become apparent from the following description, in which reference is made to the accompanying drawings.
