Abstract: An object is to provide a packaging container which can be easily recycled after being thrown away, which allows food to be heated by dielectric heating, and which has an excellent thermal insulating performance. Another object is to provide a method for manufacturing the packaging container. The packaging container includes a sleeve (12) having upper and lower ends folded inward, a film (16) which covers the sleeve (12), an inner container (11) formed inside the sleeve (12), and a lid for sealing the inner container (11). The film (16) and the inner container (11) are fused and joined integrally at folded portions of the upper and lower ends of the sleeve (12). Since it becomes unnecessary to provide a thermally activatable adhesive or the like between the sleeve (12) and the inner container (11), or to apply a thermally activatable adhesive or the like onto the inner surface of the sleeve (12), storage and handling of the sleeve (12) become easier.

Abstract: A receptacle for a beverage includes a cylindrical main body (10)having an open upper end (11) that is closed by a plastic lid (20). The plastic lid (20) is provided with an opening (23) for use in drinking or otherwise discharging the contents of the container. The opening (23) can be covered with a pull tab (30) or can be left uncovered. The lid (20) is provided with a flange (21) at a portion surrounding the outer periphery of the lid (20), and a cover film (50) is sealed to the flange (21) to cover the lid (20). The upper surface of the lid (20) is shielded from outside air by the cover film (50) and therefore can be maintained in a clean condition until the opening (23) is exposed for discharging the contents in the receptacle. Thus, dust, moisture and other contaminants are prevented from becoming deposited on the lid (20).

Abstract: In a method of filling a packaging container, a liquid is charged in a container through an opening in a top end of the container to a first level below the top end of the container. The container has a deformable portion in a wall thereof so that an inside volume of the container can be adjusted. A lid is sealed on the opening, and the deformable portion of the container is deformed to elevate the liquid above the first level.

Abstract: A pull-tab (10) for a pour opening in a surface of a lid is provided in the form of a sheet having a peripheral portion cut (17) into a ring shape with a connecting portion (15) remaining uncut so that a tab portion (20) and a body portion (30) are defined outside and inside the cut, respectively. The body portion (30) has an end portion remote from the connecting portion (15) and folded toward the back side thereof along a folding line (33) extending obliquely at an angle of 45 degrees with respect to a line connecting the end portion and the connecting portion. The pull-tab (10) is placed on the pour opening (83) and the lower side of the folded portion (31) is bonded to a surface of the upper lid (81) such that the pour opening (83) is covered with that portion of the body portion (30) located between the folded fixing part (31) and the connecting portion (15).

Abstract: A pull-tab for a liquid container according to the present invention is designed in form of a sheet, and by providing a cutting line in form of a ring, leaving a connecting sector on the periphery, it comprises a handle sector, being the portion outside said cutting line, and a main sector, being the portion inside the cutting line. By providing another cutting line in convex arc in the direction away from the connecting sector on the main sector, a fastening sector is formed. In this pull-tab, the main sector covers the pouring mouth when the connecting sector is positioned near outer periphery of the pouring mouth of the liquid container. A sector between an end of the main sector opposite to the connecting sector and a fastening sector is bonded to the surface of the liquid container. When the handle sector is lifted up and the main sector is pulled up with edges of the bonded sector as a supporting axis, the fastening sector is turned, and its forward end is stopped on the surface of the liquid container.

Abstract: A film splicer is provided in which in connecting a first film (12) and a second film (15) to each other, a residual portion cannot be formed rearwardly of a connection point of the first film (12). The film splicer includes a pair of clamping means for clamping the first and second films (12 and 15), at least one heater (67) for heating both the films (12 and 15) for heat-sealing thereof in a state in which both the films (12 and 15) have been clamped by the clamping means, and at least one cutter (71, 72) for cutting at least one of the first and second films (12 and 15) in a state in which both the films (12 and 15) have been clamped by the clamping means. The film splicer further includes a pair of arms disposed advanceably and retreatably, and the clamping means, the heater (67) and the cutter (71, 72) are mounted to each of the arms. Thus, a residual portion left rearwardly of the connection point of the first film (12) is cut away by the cutter (71, 72).
