    Abstract: A sealing device is set forth which assists in overcoming the foregoing problems. The sealing device includes a first sealing jaw for sealing a fin of the gabled container. A second sealing jaw is disposed opposite the first sealing jaw. Both the first and second sealing jaws include a generally flat face portion. The second sealing jaw further includes a sealing bar extending from a mid-region of its generally flat face portion lengthwise along at least a portion thereof for sealing the fin of the gabled container with, for example, ultrasonic energy. A ridge extends respectively from each of the generally flat face portions at a position to form a fin base crease at the base of the fin, for example, over the existing weak crease at the base of the fin. The fin base crease assists in preventing separation at the base of the fin below the principal horizontal seal formed by the sealing bar. The sealing bar may extend from the generally flat face portion of the second jaw a distance beyond the degree to which the ridges extend from their respective face portions. The ridges thus may exert less pressure on the fin than does the sealing bar.

    Abstract translation: 提出了一种有助于克服上述问题的密封装置。 密封装置包括用于密封有盖的容器的翅片的第一密封夹爪。 第二密封钳口与第一密封钳相对设置。 第一和第二密封钳口都包括大致平坦的表面部分。 第二密封钳口还包括密封条，其从其大致平坦的表面部分的中间区域沿着其至少一部分纵向延伸，以用例如超声波能量密封有盖的容器的翅片。 一个脊从各个大致平坦的面部分分别延伸到一个位置，以便在翅片的底部形成一个翅片基部折痕，例如在鳍的底部存在的弱折痕上。 翅片底部折痕有助于防止在由密封条形成的主水平密封件之下的翅片底部的分离。 密封条可以从第二钳口的大致平坦的表面部分延伸超过脊从它们各自的面部部分延伸的程度。 因此，脊可能比密封条施加更少的对翅片的压力。

    Abstract: A process for forming an easy-opening arrangement for gable-top cartons is described. A tape is applied to the inside of the pouring spout in order to stiffen the panels, while reducing the force required to separate the thermoplastic seal. The tape is bonded to the thermoplastic surface layer of the carton by an adhesive. During the hot air heating of the carton top prior to sealing, the area where the tape is located is not exposed to the hot air. During closing of the sealing jaws, surfaces on the opposed faces of the sealing jaw urge the adhesive into the space above the edge of the pouring spout to form an impermeable seal. The location of the tape on the carton blank and the apparatus for heating and sealing the carton are also described.

    Abstract: A box sealing apparatus on which a box with the bottom flaps folded is positioned on an anvil-type holder supported on a moveable arm. The folded box is then manually pushed into contact with a sealing mechanism. The sealing mechanism has a contacting face that is angularly displaced from the horizontal so that the anvil-type holder has an identical angular position when the anvil holder contacts the contacting face. After the box flaps are sealed, the holder with the sealed box thereupon is returned to the operator by gravitational force for removal of the sealed box.
