Bar of soap

Priority: March 18, 1970, England, no. 13009/70

The invention relates to multicolored die-cut bars of soap.

Two- or multi-colored bars of soap are useful to make different To identify soap types by combining the colors and to give the pieces a pleasing appearance to lend,.

A multicolored soap bar according to the invention can consist of a non-overfat base soap, which also a Contains non-soap detergent, but preferably it is made from an over-greased base soap,

The soap bar according to the invention is produced in the following manner: a multicolored bar is extruded, cut into blanks of the required length and punched in the longitudinal axial direction (on the end) to form a bar with a central mottled area, of which! emit colored stripes; the cross-sectional area of the blank must be between 25 and 50 i> the base area of the finished piece. The cross-sectional area of the blank and the base of the punched piece are perpendicular to the punching direction _o The ratio of the cross-sectional area of the blank to the base of the finished piece is referred to below as the aspect ratio.

Partly the color of each type of soap and the "P§S3§" £ size will be like this chosen to give the desired depth of color and the desired contrast in the finished product. The listed specific limits on the ratio of the cut surfaces allowed the manufacture of bars with a minimum of peripheral cracks around the median surface.

The lower limit of $ 25 in aspect ratio is determined by the feasibility of punching on the end of a narrow Raw piece determined. The upper limit of $ 50 in aspect ratio is caused by cracking of the finished piece certain pieces with an aspect ratio of $ 85 for example give, when punched on the end, pieces which tear severely with use. Pieces with an aspect ratio of $ 50 or less shows a sizeable Reduction of cracking on the surface to an acceptable extent during the first stages of its use, Moreover, if the piece is washed further, this very slight cracking disappears completely.

Some implementation examples follow. example 1

A round blank (37.5 mm in diameter) was formed from a greasy soap which had blue and white stripes and was subjected to die cutting on the end to form a round piece whose aspect ratio was $ 29.5. A small amount of cracking was visible around the tunic surface, which also remained after use in water at 40 ⁰ O, then in contact mi 'water held in a soap dish and was dried out.

Example 2

Example 1 was repeated with an aspect ratio of $ 33.5, with a result similar to that in Example 1 was received,

Example 3.

Example 1 was repeated with an aspect ratio of

45.3%, with a similar result as in Example 1 was obtained.

A sexton with an aspect ratio of 54.5? & Became also manufactured and tested, found to be a considerable amount of fine and a small amount Showed amount of deeper pillow after water treatment

Example 4

An oval blank with a cross-sectional area of 12.4cm ' and with blue and white vertical stripes became one Oily soap is made and punched onto the end to form a piece of rectangular cross-section (5.1 cm 7.6 cm) with the aspect ratio being 33%. There was only slight cracking on the central part present and after washing to 50% of the original The cracking was barely noticeable by weight

Example 5

Example 4 was repeated starting from a round blank with a cross-sectional area of 10.7 cm ² . The aspect ratio during punching was 28%. The piece formed showed the same crack behavior as Example 4.

Example 6

Example 4 was repeated starting from a square blank with a cross-sectional area of 11.2 cm. The aspect ratio during punching was 30%. The piece formed showed the same crack behavior as that of Example 5.
