Definitions

  • the present invention relates to a paper container with a spout that accommodates liquid contents.
  • a paper container for storing liquid contents such as milk or juice it is made of paperboard material with thermoplastic resin laminated on the front and back sides, and has four body panels, the edges of which are joined by a vertical seal panel. are formed at the upper end of the body panel, a pair of gable roof forming panels facing each other and having an outer top seal panel at the top, and a pair of gable wall forming panels facing each other and having an inner top seal panel at the top. are arranged in series, the pair of gable wall forming panels are folded between the pair of gable roof forming panels, and the outer top seal panel and the inner top seal panel are heated and sealed at a predetermined position.
  • a paper container with a spout of a gable roof type is widely used, in which a top portion is formed by a spout and a spout is attached to one of the pair of gable roof forming panels (for example, Patent Document (See 1).
  • the mouth plug should be shaped so that the nose does not touch the outer top seal panel at the top when the mouth is put into the mouth normally without paying particular attention to it.
  • the inventors focused on the fact that the reason why the nose hits the outer top seal panel at the top is the angle formed between the outer top seal panel and the gable roof forming panel that make up the top. The inventors also discovered that when the height of the outer top seal panel and the spout are constant, the larger the angle between the outer top seal panel and the gable roof forming panel, the more difficult it is for the nose to hit the outer top seal panel. Ta.
  • the angle between the outer top seal panel and the gable roof forming panel is proportional to and determined by the slope angle of the gable roof forming panel, such that as the slope angle of the gable roof forming panel increases, the angle between the outer top seal panel and the gable roof forming panel increases. The angle between the seal panel and the gable roof forming panel also increases.
  • the inventors determined the angle of inclination of the gable roof forming panel to prevent the nose from hitting the outer top seal panel at the top when the mouth is normally touched without paying special attention to the spout. As a result of repeated tests, it was determined that due to the height of the spout, when you put your mouth on the spout without paying special attention to it, your nose would not hit the outer top seal panel at the top.
  • the present invention was completed by discovering the inclination angle of the roof forming panels.
  • An object of the present invention is to provide a paper container with a spout that allows easy drinking when the user puts the spout directly on the spout and prevents the risk of spillage.
  • the invention according to claim 1 is made of a paperboard material with thermoplastic resin laminated on the front and back sides, and has four body panels, the edges of which are joined by a longitudinal seal panel.
  • a body is formed, and at an upper end of the body panel, a pair of opposing gable roof forming panels having an outer top seal panel at the top and a pair of opposing gables having an inner top seal panel at the top.
  • the wall forming panels are arranged in a row, the pair of gable wall forming panels are folded between the pair of gable roof forming panels, and the outer top seal panel and the inner top seal panel are heated and sealed at a predetermined position.
  • the gable roof forming the top part is formed by attaching a spout to one of the gable roof forming panels of the pair of gable roof forming panels.
  • the inclination angle of the forming panel is such that the tip of the sealed outer top seal panel at the top does not exceed an extension of the plane of the top portion of the spout.
  • the inclination angle of the gable roof forming panel forming the top portion is such that the tip of the sealed outer top seal panel at the top portion is an extension of the plane of the top portion of the spout. Since the angle does not cross the line, the inclination angle of the gable roof forming panel becomes large, and when the mouth is attached to the spout, the nose is prevented from hitting the sealed outer top seal panel at the top.
  • the liquid contents can now be dispensed directly from the spout without having to pout to avoid hitting the outer top seal panel with the nose or moving the upper lip far away from the spout when drinking. can be easily drunk. Furthermore, since there is no need to move the upper lip far away from the spout when drinking, it is possible to prevent the liquid contents from spilling from the spout.

  • the paper container 1 with a spout of this example is made of a paperboard material with thermoplastic resin laminated on the front and back surfaces, and includes four body panels 2, 3, 4, and 5, whose edges are joined by a vertical seal panel 6. Then, the body portion 7 is formed.
  • a pair of gable roof forming panels 10 and 11 facing each other and having outer top seal panels 8 and 9 at the upper part are arranged in series, and at the upper ends of the body panels 3 and 5.
  • a pair of gable wall forming panels 14 and 15 facing each other and having inner top seal panels 12 and 13 at the upper part are arranged in series, and the gable wall forming panels 14 and 15 are arranged between the gable roof forming panels 10 and 11. 15 is folded in and the outer top seal panels 8, 9 and inner top seal panels 12, 13 are heated and sealed in place to form a gable roof top 16.
  • the trunk panels 3, 5 and the end wall forming panels 14, 15 connected to the upper ends of the trunk panels 3, 5 are Although it is partitioned by top transverse fold lines 17 and 18 formed between the upper end and the end wall forming panels 14 and 15, the trunk panel 2 , 4 and the gable roof forming panels 10, 11 which are connected to the upper ends of the body panels 2, 4, there is no top transverse fold line, and they are connected without a partition.
  • the gable roof forming panels 10 and 11 forming the top part 16 formed by folding the gable wall forming panels 14 and 15 between the gable roof forming panels 10 and 11, the body panel 2 forming the body part 7, 4 has a shape in which the portions where the gable roof forming panels 10 and 11 are connected to the upper ends of the body panels 2 and 4 are bent into an arc shape (see FIG. 3).
  • folding lines 19, 20, 21, 22 for folding the end wall forming panels 14, 15 are formed on the end wall forming panels 14, 15.
  • a spout attachment hole 23 is formed in one of the gable roof forming panels 10 and 11 forming the top portion 16, and a spout 24 is attached thereto.
  • the spout 24 is preferably arranged so that its center is below the center of the gable roof forming panel 11.
  • the inclination angle ⁇ of the gable roof forming panels 10 and 11 forming the top portion 16 is such that the tips T of the sealed outer top seal panels 8 and 9 at the top portion 16 are at the top of the spout 24 attached to the gable roof forming panel 11. The angle does not exceed the extension line L of the plane F of the part.
  • the inclination angle ⁇ of the gable roof forming panels 10 and 11 forming the top portion 16 is set at the tip of the sealed outer top seal panels 8 and 9 at the top portion 16. is at an angle that does not exceed the extension line ll of the plane F of the top portion of the spout 24 attached to the gable roof forming panel 11, so the inclination angle of the gable roof forming panel becomes large.
  • the user takes a sip it is possible to avoid hitting the nose with the outer top seal panels 8 and 9 in the top part 16, and the liquid contents can be easily drunk directly from the spout 24.
  • the inclination angle ⁇ of the gable roof forming panels 10 and 11 forming the top portion 16 is an extension of the plane F of the top portion of the spout 24 attached to the gable roof forming panel 11, where the tips T of the outer top seal panels 8 and 9 are attached to the gable roof forming panel 11. Since the angle does not exceed the line L, the inclination angle ⁇ of the gable roof forming panels 10, 11 increases, and the area of the gable roof forming panels 10, 11 increases accordingly.
