Definitions

  • the patent specification DE-C-156604 describes a method for producing bottle and tube sleeves from corrugated cardboard softened with glue vapors.
  • these sleeves are completely wrapped around the bottles and vessels. to make them shockproof for handling.
  • the wrapper of the invention consists of thin crepe paper with a thickness of only 0.20-0.35 mm. Softening with water is not necessary. Rather, the adaptations of the wrappings to the vessels and bottles are achieved by means of elasticity due to the specific fiber orientation and the defined stretching transverse to the longitudinal direction of the vessels.
  • the coverings of the invention are practically wrinkle-free and crack-free, and they can be dried uniformly by quickly diffusing out the small amount of water from the glue dispersion.
  • the invention relates to a method for producing aluminum-free casings for all kinds of vessels and for bottles according to the preamble of claim 1 (see DE-C-156604).
  • the achievement of the object of the invention is also characterized in that crepe paper with an elongation transversely to the longitudinal direction of the vessel or bottle is used between 12 to 14%.
  • the method of the invention is also characterized in that the crepe paper is used with a crepe height between 0.25 to 0.27 mm and a thickness between 0.26 to 0.30 mm.
  • the method of the invention is further characterized in that the crepe paper is used with a basis weight between 60 to 120 g / m2 and in that it is used with a basis weight between 70 to 85 g / m2.
  • crepe paper with a breaking load in the transverse direction for creping between 20 to 35 Nmm and / or with a breaking load in the longitudinal direction for creping between 25 to 35 Nmm is used.
  • crepe paper with a breaking load in the transverse direction for creping between 25 to 30 Nmm and / or with a breaking load in the longitudinal direction for creping between 28 to 30 Nmm is used.
  • crepe paper with a Gurley air permeability between 3.0 to 5.0 sec / 100 ml is used, and between 3.2 to 4.0 sec / 100 ml is used.
  • the method of the invention is also characterized in that the envelopes are printed on underprinting ink with printing ink or with heavy metal-free pearlescent pigment before being glued on.
  • the wrappings are glued to the bottle necks of beverage bottles such as beer bottles with a cylindrical shape, or with a conical shape, or with a continuous widening of the radius in the direction of the bottle bottom or the bulge, and in that the wrappings are spaced below a closure can be glued to this or to the lower edge thereof and in that the wrappings have a cut which projects beyond the closure at such a height that it is folded and glued practically tightly.
  • a technical effect of the aluminum-free envelopes of the invention is based on the combination of essential features by the firm pressure in the dry state on the different spatial shapes of the vessels of all types and bottles, while practically avoiding the formation of folds.
  • This technical effect is essentially caused by the elasticity of the wet-strength and alkali-resistant crepe paper, expressed as elongation in% to the vessels or bottles.
  • a longitudinal expansion of, for example, 14% means the expansion of the length from 100 to 114 mm.
  • the crepe height is understood to mean the distance in mm between the upper and lower points, i.e. between the vaulted mountain and the vaulted valley.
  • the longitudinal stretching or the transverse stretching of the crepe paper is not suitable for adaptation to the surface of the containers or bottles.
  • Another technical effect is formed by the weight per unit area. If this is too low, the crepe paper is not strong enough, if it is too large, the crepe paper lacks the elasticity to adapt to the surface of the containers or bottles.
  • Another technical effect is the air permeability of the crepe paper. If this is too low, the liquid, especially the aqueous, phase of the dispersion of the adhesive cannot diffuse out of the crepe paper in practice.
  • Air permeability is the Gurley measurement. Its definition is published in ISO standard 3687.
  • Stretching the crepe paper of the invention means the increase in length in% of the length before stretching.
  • glue dispersions are used, the liquid and aqueous phases of which diffuse out of the crepe paper and evaporate.
  • the coverings are pressed on mechanically by means of brushes or sponges or rollers.
  • the casings for all kinds of vessels and for bottles of the invention offer the technical advantage of substituting aluminum light metal foil with the same suitability for safe and permanent use for gluing and pressing onto the shaped surfaces of these objects.
  • the wrapping of the invention made of crepe paper prevents pollution of the environment, in particular of the watercourses, and thus also of the soils due to the rotting to the C source for the microbial decomposition to humus product.
