Abstract
An improved transparently packaged bar, having increased light transmission, and a method of manufacture thereof is disclosed. The packaged bar has an increased level of light transmission which is believed to be caused by the cooling of molten soap in direct contact with the stretchable transparent wrap which is used to package the bar. The bar has an unique shape which enhances its light transmission. The bar may also contain voids which enhance the appearance of the soap bar or reduce its density, or both. The soap bar, and method of manufacture, are particularly well suited for transparent, translucent, and pearlescent soaps, or a bar which is poured with a combination thereof. Additionally, objects both solid and amorphous, and flexible or rigid, may be placed within the bar which have an enhanced level of visibility inside the packaged soap bar. If desired, hues or pigments may be dispersed through some portion of the soap bar to obtain a desired artistic appearance. Further force may be applied to the top of the poured bar, or to the film into which the molten soap is poured to effect a curved shape having a smaller radius of curvature, or to allow the use of thicker or stro…
