Definitions

  • Soap bars are often sold in a two-part package comprising a stiffener and an overwrap.
  • the stiffener may be made of a plastic or paperboard.
  • the overwrap is also usually made of a plastic and may be transparent, translucent or opaque.
  • Such packages are very familiar to consumers, but it is desirable to provide a soap bar package which also minimizes packaging material and at the same time contains a structure which is pleasing to consumers’ visual and/or tactile senses.
  • Bronander US Patent No. 4,406,364 discloses a wrapped combination of a cake of soap and a disposable receptacle or tray. Advertising material can be placed on the overwrap and/or tray.
  • Moss US Patent No. 6,520,322 discloses a bar of soap having a stiffening member. At least a portion of the stiffening member is transparent to allow the soap to be viewed.
  • the wrapper may comprise a film having a transparent part.
  • Chakraborti et al. US Patent Application Publication No. 2010/0193381 discloses a stiffener for use in packaging detergent bars having a plurality of ribs along its cross direction. According to Chakraborti et al., such stiffeners would have relatively higher stiffness in the cross direction and would be less prone to deformation along the lateral edges and sides of the package. Chakraborti et al. also mention use of a corrugated sheet of paper as stiffener.
  • Chakraborti et al s plurality of ribs are formed by softening a tensioned sheet of paper by contacting it with a softening agent, passing the tensioned sheet between a pair of counter currently rotating grooved rollers operating under pressure to form a plurality of ribs, and passing the sheet through a heating zone.

  • a cylindrical die is preferred.
  • a die having raised portions is impressed on the stiffener material and it is the raised portions which contact the stiffener material to create the debossment in the stiffener material.
  • the die will have depressions which, when imposed on the stiffener material, will create the embossment(s).
  • two dies can be used, one with depressions and one with raised portions, with the stiffener material interposed in between such that the raised portions contact the stiffener material and the raised portions fit within depressions on the second die to create the embossment.

Abstract

L'invention porte sur des structures de barres de savon emballées, un procédé de fabrication de celles-ci et un appareil pour leur fabrication. Dans le paquet de savon selon un mode de réalisation, un raidisseur (14) est pourvu de reliefs ou d'évidements et est enveloppé par un matériau transparent ou translucide (12) pour créer un effet visuel tridimensionnel pour le consommateur le long de la surface de l'emballage. Dans un autre mode de réalisation, l'emballage (12) est pourvu de reliefs/évidements pour offrir une sensation tactile distinctive. Selon un autre mode de réalisation, le raidisseur et/ou l'emballage avec des reliefs/évidements sont fabriqués en partie en imposant une matrice sur les matériaux du raidisseur et/ou de l'emballage, de préférence pendant la procédure d'emballage, en particulier après que les matériaux du raidisseur et/ou de l'emballage ont été déroulés pour l'emballage. Dans un autre mode de réalisation encore, l'élément de raidissement (14) peut comprendre une fenêtre (82), par laquelle les reliefs/évidements sur la barre de savon ou un autre article peuvent être vus à travers le matériau d'emballage transparent ou translucide (12) et à travers la fenêtre dans le raidisseur depuis l'extérieur du récipient emballé.
