Definitions

  • the present invention relates to a method wherein a label made of a synthetic resin sheet is wrapped around the whole periphery of the side surface portion of a container and both end portions of the label are joined to each other by using a solvent to dissolve the synthetic resin sheet.
  • the surface of the label made of the synthetic resin sheet is printed.
  • the adhering force is remarkably reduced.
  • no printing is performed to the overlapped portions to be joined, so that the synthetic resin sheet portion is exposed to the surface.
  • the display or graphic image pattern which was printed in the leading edge portion of the label and the display or graphic image pattern which was printed in the trailing edge portion are completely made continuous in the overlapped portions. Therefore, the display function of characters or graphic image patterns as a main function of the label is remarkably limited and the external appearance is also fairly marred.
  • the cutting positions are deviated. Therefore, it is demanded to work at an extremely higher accuracy than that in the ordinary cutting work. Further, the label have to be worked also in consideration of the above-mentioned deviation of the print positions. Therefore, in the case of using the ordinary cutting apparatus, the synthetic resin exposed portion C of the label made of the synthetic resin sheet have to be set to be further wider than the overlapped portion A. An inconvenience such that the display function as a main function of the label is injured becomes further noticeable.
  • the present inventors intend to provide a method of joining two end portions i.e. leading edge portion and trailing edge portion of a label wherein in the case of joining the front end surface and the rear end back surface of a label of a synthetic resin sheet by using a solvent to dissolve the label, the continuous display function of characters or graphic image patterns of the front end surface portion and the rear end back surface portion of the label may be guaranteed without adding any limit condition, the external appearance of the label is not injured at all, the printing and cutting works of the label can be easily performed by the printing cutting works of the ordinary accuracy or even by an apparatus which is simpler than the ordinary one, and after the label was adhered, the adhering strength can be held sufficiently and strongly held.
  • front end surface portion A to be overlapped with a rear end back surface portion of a label comprises a printed portion B and a portion C in which the printing is not performed and a synthetic resin sheet portion of the label is substantially exposed, and after a solvent to dissolve the synthetic resin was coated to the rear end back surface portion of the label, the front end surface portion and the rear end back surface portion of the label are joined to each other.
  • the front end surface portion A of the label contains at the rate of at least 10% thereof, the portion in which no ink exists and the synthetic resin sheet portion is substantially exposed and that after the solvent to dissolve the synthetic resin was coated onto the rear end back surface portion of the label, the front end surface portion and the rear end back surface portion of the label are joined to each other.
  • Containers mentioned in the present invention denote containers made of various kinds of raw materials such as paper, synthetic resin, metal, glass, or the like. They may be shaped as a cup, a bottle, a tray, a can, or the like, having a straight portion of at least 4mm or more as the side surface.
  • the synthetic resin sheet mentioned in the invention denotes a film, a foamed sheet, or a laminated sheet having a combination of a film layer and a foamed layer which has a thickness in a range from 0.01 to 1.00 mm.
  • the synthetic resin which is used in the synthetic resin sheet needs to be dissolved by the solvent which is used for adhesion. Therefore, a raw material of the synthetic resin sheet and a solvent are mutually selectively determined.
  • various kinds of solvents such as methylene chloride, 1-1-1-trichloroethane, tetrahydrofuran, or the like may be used as solvents.
  • tetrahydrofuran is mainly used as a solvent.
  • synthetic resins polystyrene, polyvinyl chloride, polyacrylate, polyethylene, vinylidene chloride, EVA, etc. can be employed.
  • a method of joining the front end of the label to the container a method of coating an adhesive agent to the label or a method of using a solvent to dissolve the label material may be generally used.
  • a sheet having the shrinkable performance one-directionaly is ordinarily used.
  • a sheet such as biaxial-oriented sheet or balance-oriented sheet which hardly shrinks thermally.
  • the label which may be used to carry out the invention may be either of thermally shrinkable or nonshrinkable. It is sufficient to properly select a suitable shrinkage ratio in accordance with the shape of container.
  • a number of label patterns are successively printed on a long sheet and the long film is wound up like a ring and is fed to a label mounting apparatus in such a state.
  • the labels are continuously supplied from the ring.
  • the labels are cut out to a predetermined length one by one.
  • a mark provided at the cutting position on the label is read by a reader attached to the label mounting apparatus and , thereafter, the label is cut out at the mechanically controlled position so as not to cause a deviation of the position.
  • the cutting accuracy is set to a value within a range of about ⁇ 0.1 to ⁇ 2.5 mm. If the cutting accuracy is restricted to a value within a range of 0 to ⁇ 0.1 mm, an extremely expensive and complicated machine is required and the productivity is also remarkably deteriorated.
  • a photogravure printing system or the like is used as a printing system of the label.
  • the positioning printing accuracy of each color lies within a range of about ⁇ 0.3 to ⁇ 1.0 mm .
  • it is obliged to fairly reduce the production efficiency and to use an expensive printing machine.
  • a resin, a pigment, or a dye which has a good strong resistance for the solvent is used as an ink.
  • a method wherein a top coating is performed on the surface layer on the ink to thereby enhance the solvent resistance is used. Therefore, if the ink exists, the joining force of the solvent to dissolve the label is remarkably weakened. Therefore, if a printing position deviation or a cutting position deviation never occurs, the adhering strength and the continuity of the graphic image pattern are preferably held.
  • the front end overlapped portion A of the label comprises: the printed portion B; and the portion C in which no printing is executed and the synthetic resin sheet portion is substantially exposed.
  • the printed portion B can be related to characters or graphic image pattern in the label front end portion.
  • the exposed portion C of the synthetic resin sheet is overlapped to the portion of the label rear end portion F which was dissolved by the solvent and is integrated, so that a predetermined stable adhering strength is held.
  • the function of the label wrapped around the whole periphery can be performed without injuring the display function as a main function of the label in the overlapped portion as in the conventional technique shown in Figs. 5 and 7.
  • the label not only manufacturing working steps of label can be simplified but also, as shown in Fig. 11, when the label is thermally shrinked to adhere onto the container, after the label was attached, the synthetic resin sheet exposed portion C of the label directly and instantaneously reacts to the solvent coated portion F of the rear end back surface portion of the label, so that the adhering strength more than a predetermined limit value can be performed, and therefore, the front and rear end portions of the label can not be peeled off by the contraction force of the label.
  • the display functions of the front and rear end portions of the label are continuous in terms of the design.
  • the overlapped portions of the synthetic resin sheets at both ends of the label are not integrated.
  • the adhering force is weakened and as shown in Fig. 11, the front and rear edges of the label can be peeled off (peel back phenomenon).
  • the overlapped portions can be detached from each other.
  • the invention was carried out by using a label made of thermally shrinkable foamed polystyrene sheet and comprising two layers of a skin layer and an foamed layer as a synthetic resin sheet.
  • the label had a thickness of 150 to 180 microns and exhibited a thermal shrinkage ratio of 50 to 60 % at about 120°C.
  • the ordinary photogravure roll printing was used as a printing system. The printing was executed at a color position accuracy within ⁇ 0.8 mm.
  • For cutting there was used a system in which the ring as shown in Fig. 1 was attached to the labeling machine and the label was successively cut out of the ring by a fixed knife and a rotating knife. The cutting accuracy was within ⁇ 0.7 mm.
  • As an ink the ink containing the acrylic resins was used. A solvent of tetrahydrofuran was used.
  • the initial adhering strength of the overlapped portion was 0.05 Kg/cm or less and was not able to resist the thermal shrinkage force of the label of 0.1 Kg/cm or less.
  • the tensile strength of the overlapped portion almost instantaneously became 3.0 to 4.0 Kg/cm after it was joined.
  • the adhering strength which was extremely larger than the thermal shrinking force could be performed.
  • Figs. 8 to 10 are schematic views showing another embodiment of the invention and relates to an example in the case where in order to join the label end portions, the portion having the function to hold the adhering force was not provided for the whole surface of the overlapped portion A but an exposed portion of the synthetic resin sheet portion was provided on a partial surface except a pattern or the like to be printed.
  • the portion A comprises a portion coated with an ink (black portion in the view) and a portion with no ink (white portion in the view). An area ratio of the portion to which no print ink was coated was determined in accordance with the adhering strength which was required.
  • the area ratio of the exposed portion of the synthetic resin to the overlapped portion A should be at least 10%.
  • Fig. 9 shows an embodiment in the case where in the portion A, the ink portion was set to 50 % and the synthetic resin sheet exposed portion was 50%. The initial tensile strength of the adhered portion was held within 2 ⁇ 3 Kg/cm.. In the thermal contraction step, a peel back phenomenon of the overlapped portion did not occur.
  • the label is attached to the machine at a high speed, if the working accuracy in each step is limited, its efficiency remarkably deteriorates.
  • the inherent function of the labeling machine that is, the function for stably labeling at a high speed was not lost. Further, no restricting condition is added to the display function as a main function of the label. Those functions can be perfectly made effective.
