As disclosed in Publication No. 164122 and Japanese Utility Model Application Publication No. 58-79504, a pair of triangular ears protrudes from the top wall of the finished container to both left and right sides of the top of the unfinished container. Fold it so that the upper edge rib for the horizontal seal protrudes upward from the top wall of the completed container and both triangular ears.
The upper end of the vertical seal is bent into a curved shape, the lower part is folded down so that it overlaps the lower surface of the triangular ear, and the upper edge rib is sandwiched together with the upper end of the vertical seal part with a heating plate to seal it. In this case, it is known to use a heating plate having a curved heating surface that matches the shape of the upper end of the vertical seal part. For example, if a heating plate with a flat heating surface is used, the heating plate will crush the curved upper end of the vertical seal portion.

A method of sealing the top of a bottomed square cylindrical unfinished container filled with contents, in which a pair of triangular ears are attached to the left and right sides of the top of the completed container from the part that will become the top wall of the completed container. The upper edge rib for the horizontal seal is folded so that it protrudes upward from the top wall of the finished container and both triangular ears. When folded, the upper end of the vertical seal is bent into a curved shape and folded downward. The lower part of the triangular lug is folded down so that it overlaps the lower surface of the triangular lug, and when the upper edge rib is sandwiched and sealed with the upper end of the vertical seal part on a heating plate, the lower part of the triangular lug bulges out laterally. The base of the triangular ear is sandwiched from the front and back so that the vertical seal part can rise freely.

and a pair of left and right triangular ear portions 27 and 28 connected to the left and right side walls 17 and 18, respectively. Horizontal fold lines 29 and 30 are formed at the boundary between the front side wall 15 and the front top wall planned portion 25 and the boundary between the right side wall 18 and the right triangular ear planned portion 28, respectively. Although not shown, horizontal fold lines are also formed in the same way at the boundary between the rear side wall 16 and the rear top wall planned portion 26 and the boundary between the left side wall 17 and the left triangular ear formation portion 27, respectively. Each horizontal fold line is connected to each other in a ring shape. The vertical crease line 21 of the body portion 12 is located at the ridgeline formed by the adjacent top wall portions 25 and 26 and the triangular ear portions 27 and 28.
~24 is continuing to grow. Both top wall planned parts 25, 26 and triangular ear planned parts 27, 2

に折れ曲がる。 In the irregular folding step B, a pair of levers (not shown) that can be opened and closed are inserted into the container 51, and by opening the levers, the inner surfaces of the upper edges of both the top wall portions 25, 26 and the triangular ear portions 27, 28 are aligned. This is done by spreading the triangular ear portions 27 and 28 in opposite left and right directions so that they overlap with each other, and pressing the upper edges of the same with scissors (not shown) or the like to push them downward. As a result, the planned top portion 13 is formed on the front and rear side walls 15,1
Each of the upper edges of 6 and the expected body part 12
A top wall 41 that covers the top opening, a pair of left and right triangular ears 42 and 43 made of double the thickness of the container material that are connected to the left and right edges of the top wall 41 and the upper edges of the left and right side walls 17 and 18, respectively, and The top wall 41 and both triangular ears 4 reach the apexes of the triangular ears 42 and 43.
2, 43 is transformed into an upper edge rib 44 that is twice as thick as the container material and extends in the left-right direction. During this deformation, as shown in detail in FIG. 2, the left and right vertical seal parts 19,
The lower portions of the triangular ears 42 and 43 are bent so as to overlap with each other, but the upper portions of the triangular ears 42 and 43 are bent in a curved manner so that no excessive force is applied thereto.

面に含まれている。 The heat-sealing preparation step C is performed by gently sandwiching the folded container 52 from the front and back using a lever (not shown) that can be opened and closed. As a result, the planned top portion 13 does not completely return to the state before the crease was formed, but neither the left and right triangular ears 42, 43 retain their shape, and the left and right vertical seal portions 19, 20
The curved part at the top remains until it disappears. In this state, the upper edge rib 44 is slightly opened, but is generally in a straight line, and the upper edge rib 44 and the upper portions of the left and right vertical seal portions 19 and 20 are included in approximately the same plane.

As a result, the inner surfaces of the upper edge ribs 44 are joined together. Of course, instead of heat sealing using a hot disc, heat sealing using high frequency or ultrasonic waves is also possible.
