Description of the invention () The invention: The present invention relates to a cardboard container often used for packaging liquids such as milk and juice. This container is made of a single piece of cardboard. Usually, one or more layers of barrier material will be coated on the inner and outer sides of the container as a surface, cut and scored to make it stand and fill it with an automatic machine. Liquid package with triangular top. As you know, such a container has a flat bottom and a triangular top or roof facing, and when the latter is opened, 'a pour-out outlet is formed. One intermediate step for making this container is to make a cylindrical shape from a flat plate. After the cylindrical shape is formed, the rear end is sealed and then filled with liquid. Background of the invention: When making a container with a triangular top from a single piece of flat panel with wall panels arranged continuously, the step required to form a tube is to fold the flat panel, so the fifth or edge seam panel will be stacked on top of the first On the edge area of the free edge portion of the side wall type panel. The inner surface portion of the carton of the first panel is heated so as to locally melt the common polyethylene coating and generate stickiness. Similarly, the portion of the fifth or edge seam panel used to make surface contact with the free edge region of the first panel is also heated to make its polyethylene coating tacky. Now the cross-sectional profile of the folded plate is generally a shallow diamond. When force is applied to the two panels to fold the diamond tube, the force will be applied to the edge of the folded plate or plate to make it the edge of the first panel. The areas are partially sealed. When closing the bottom carton, the 'side seam will often be cut. Use a specific cut.

Description of the invention () The cutting tool / method will inevitably produce a tapered end at the edge seam or one end of the fifth panel. This tapering end will cause a part of the triangle in the edge area of the first panel not to be covered. Therefore, when the first and fourth panels are pushed down, the edge gap (the fifth) panel faces the edge of the second panel. When the area is tightly sealed, a part of the second panel will contact the hot and sticky triangular part exposed by the first panel, resulting in the first panel triangular area and the second panel triangular area near the tapered end of the side seam panel. Unwanted adhesion between. In order to avoid such undesired adhesion, the temperature of the edge portion of the first panel and the temperature of the fifth or side seam panel are reduced to reduce the viscosity. When solving the problem of undesired adhesion, this decrease in temperature will reduce the strength and quality of the seal between the side seam and the first panel. The degradation of the quality of the liquid carton is unfavorable for the expectation of prolonging the storage life. Purpose and Summary of the Invention: According to the implementation of the present invention, the undesired adhesion between the second panel and the edge seam joint structure attached to the first panel is The second panel was cut out of a gap to be excluded. The trimmed portion coincides with the diagonally cut or truncated portion of the tapered end forming the side seam of the fifth panel. In this way, when the first panel is pressed against the edge seam panel, no hot and sticky exposed areas of the first panel will adhere to the second panel.

Description of Invention () Board 1 2 When the side seam is joined or seamed with 20, the hot and sticky part 30 on the panel 12 will stick to the corresponding part 30a of the second panel 14. The next step in which this tube becomes a triangular top carton will be rendered useless by this adhesion. In the past, the softening temperature of thermoplastic materials (typically polyethylene) on the surfaces of panels 12 and 20 could only be lowered to eliminate this problem, but at the cost of poor edge seam bonding. Referring now to Fig. 3, the difference between the flat plate of U.S. Patent No. 5,626,285 and the flat plate of Fig. 1 can be seen, except that the triangular area bounded by tangents 34 and 36 is removed. Referring now to FIG. 4 ', when the panels 14 and 16 are pressed down to form a side seam joint, the panel 12 will have no area or a portion exceeding the tapered end 28 and adhere to the panel 14 in the area 30A. Therefore, except for the tangent lines 34 and 36 and the triangular area 30 in the second figure which disappears, everything shown in the fourth figure is traditionally common. The gaps shown in Figs. 3 and 4 -M are triangles with tangents 34 and 36 as the boundary. The edges 28 and 34 are consistent. However, if necessary, the tangent line 36 may be curved or may be bitten down in a straight line parallel to the area 40, and may be used instead of the angle in the third figure. As mentioned earlier, the actual / retrograde step of forming the seams in Figures 2 and 4 is performed by rotating the long axis of the cylindrical wall formed by the side wall and the fifth panel 20 by 180 degrees. When the paper box described in U.S. Patent No. 5,626,285 is applied to a small-sized paper box, it will be said that y ^ avoids a difficulty before being filled with an automatic machine to form the bottom of the box. The cut of the first panel will hinder the triangular top between the first and fourth panels to be folded flawlessly. Therefore, the gap will be determined by Chu ^.

Description of the invention () Moved to the second panel but ㈣ corresponds to the truncation due to the sticky folding plate It is advantageous to form exposed sticky locations. (Please read the precautions on the back before filling out this page} Now referring to Figure 5, you will see the flat plate of the present invention. The second panel " has a cutting edge composed of free edges 134, 136. Edge 136 corresponds When forming the cylindrical carton, the boundary line 34 of the truncated edge after the viscous flap 20 is combined with the first panel 12 and the free edge 134 extends from the edge 136 to the bottom of the third panel 16. The description in FIG. When the tube is flattened, how will this cutting opening be pressed onto the adhesive area 30 that is exposed when the adhesive folding plate 20 is pressed onto the adhesive area 40 of the first panel 12. The free edge 136 of this cutting opening corresponds to To the truncated edge of the adhesive folding plate 20, so the exposed adhesive area 30 will not contact the part of the second panel 14 of the carton. In this way, the undesired adhesion when the tube is flattened can be avoided. When When flattened, the first and fourth panels 12, 18 form a lower layer, and the second and third panels 14 and 16 form a higher layer. The upper layer has no parts that might adhere to the lower layer. The carton will use this The form is shipped until it is finally made into a filled and sealed carton.
