  Hereinafter, a bi-fold packaging container according to an embodiment of the present invention will be described in detail with reference to the drawings. Drawing 1 is a figure showing the state after bending of the half-fold packaging container concerning one embodiment of the present invention in the state seen from the film surface side. FIG. 2 is a vertical cross-sectional view showing the folded state of the bi-fold packaging container according to the embodiment of the present invention.

  As shown in FIG. 1 and FIG. 2, the packaging container 1 is formed by superposing films 2 and 3 made of flexible synthetic resin packaging materials, both of which have the same single layer configuration or the same laminated configuration, It is made into the state bent so that it may become convex toward the upward bending position. In addition, a seal portion 4 is formed by using a heat sealing method on opposite sides of the outer film 2 and the inner film 3 when folded downward in a substantially triangular shape. Of the pair of seal portions 4 that are the lower portion of the container in this folded form, one seal portion 4 has the same unit as the films 2 and 3 between the film 2 and the film 3. A film 5 having a layer structure or a different single layer structure, or the same or different laminated structure is folded, and the opposite sides of the film 2 and the film 5 and the opposite sides of the film 3 and the film 5 are separated. It is provided so that it can be developed by heat sealing and opening between the film 2 and the film 3.

  The upper bent portion 2a of the outer film 2 and the lower bent portion 3a of the inner film 3 are not in contact with each other, and the lower bent portion 3a is disposed away from the upper bent portion 2a on the container lower side. Since the upper bending portion 2a and the lower bending portion 3a are separated from each other in the vertical direction, the outer films 2 are opposed to each other above the lower bending portion 3a. In each of the sides on both sides of the opposed outer film 2, the sealing portions 4 are formed by heat-sealing the films 2 to each other. The seal part 4 at the side of the film 2 and the side of the container 3 of the film 3 and the seal part 4 above the lower bent part 3a (the seal part 4 on each side of the film 2) are continuous. Even along the bent portion of the outer film 2, a seal portion 4 formed by heat-sealing the films 2 is provided across the container width direction. The seal portion 4 extending in the container width direction is continuous with the side seal portion 4. In this manner, the upper bent portion 2a for folding the outer films 2 at the top of the packaging container 1 is configured as a seal portion 4 made of heat seal.

  The storage unit 6 is configured by stacking two films 2 and 3 to face each other and arranging the film 5 in the lower part of one container. The storage part 6 is divided into two regions via a bent part 7 between the upper bent part 2a and the lower bent part 3a. The two regions communicate with each other with the bent portion 7 therebetween.

  As shown in FIGS. 1 and 2, one side in the longitudinal direction of the bent portion 7 on the upper side of the container, that is, one side in the container width direction is lateral to the container so as to be continuous with the portion of the bent portion 7. A spout 8 that is convex toward the surface is located. The shape of the spout portion 8 which is convex toward the container side is such that the seal portion 4 on the side of the spout portion 8 side of each region where the storage portion 6 is divided into two is the center of the storage portion 6. It is formed by getting into the side. As shown in the drawing, the seal portion 4 on the same side in each region where the storage portion 6 is divided into two curves so as to be recessed toward the inside of the storage portion 6 in the vicinity of the height position of the lower bending portion 3a. A curved seal portion (recessed portion) 9 having the shape described above is provided. Thus, the curved seal portion 9 has a shape recessed toward the inside of the storage portion 6 below the spout portion 8 and in the vicinity of the height position of the lower bent portion 3a. The seal portion 4 positioned above the height position of the lower bent portion 3a is formed continuously with the seal portion 4 positioned lower than the height position of the lower bent portion 3a.

  In the lower part of the spout 8, a curved seal part (dent part) 9 having a shape recessed toward the center of the pouch is provided at a position below the position of the lower bent part (bending planned line) 3 a. The curved seal portion (recessed portion) 9 has a form that can be hooked on the bottle when the contents are poured out. The seal portion 4 on the protruding end side of the spout portion 8 is continuous with the lower seal portion 4 of the spout portion 8 and is further continuous with the seal portion 4 of the curved seal portion 9.

  The packaging container 1 is folded in half into a substantially triangular shape that opens downward, but by opening the bend at the position of the folded part so that the seal part 4 that does not fold the bottom film at the bottom of the container is on top, The storage portion can extend in the vertical direction of the container to form a vertically long container. FIG. 3 is a view showing the stretched state of the two-fold packaging container according to one embodiment of the present invention as seen from the film surface side. FIG. 4 is a view showing, in a longitudinal section, a stretched state of a two-fold packaging container according to an embodiment of the present invention.

  As shown in FIGS. 3 and 4, when the bi-fold packaging container 1 is elongated vertically, the container 6 divided into two via the bent part 7 forms a single storage space. It is extended vertically. Then, the inner film 3 with the lower bent portion (bending line) 3a opened and the outer film 2 opened by folding from the crease 10 at the height corresponding to the lower bent portion 3a are opposed to each other. The film 5 is unfolded to form a standing pouch type shape that forms a satisfactori container bottom. 3 and 4 show a state in which the seal portion 4 located at the upper part of the container is opened in the standing state.

  The folding ruled line 10 is put in advance at a position corresponding to the lower bent portion 3a in the outer film 2 in the form of folding in two. When changing from the folded state (folded state) to the standing state, the outer film 2 is bent by the crease 10, and the bottom film 5 is not interposed from the upper bent part 2a (on the side opposite to the bottom film 5). When the area up to 4 is raised, the container is in a standing state. 3 and 4, the bent portion 7 and the upper bent portion 2a face upward in the standing state. However, the bent portion 7 and the upper bent portion 2a may face downward in the standing state.

  In this way, the outer film 2 is bent with the position of the lower bent portion (bending line 3a) 3a as the axis (upper or lower), and the inner film 3 that has been bent in reverse is extended, so that the container Upright and standing. The bent portion 7 and the upper bent portion 2a of the outer film 2 are provided so as to overlap with the region of the container positioned in the standing state (the region sandwiched between the outer film 2 and the inner film 3). It is designed so that the shape of the standing pouch is not impaired.

  In the two-fold packaging container 1, it can be set as the form of a standing pouch by providing the gusset part which consists of the bottom film 5 in the lower part of a pouch. For example, when the standing pouch is opened at the position of the bent portion 7, the gap between the opposite sides of the outer film 2 and the inner film 3 at the upper part of the container located on the opposite side of the container bottom is opened. Use an unsealed filling port. A standing pouch-type package is obtained by heat-sealing the opposite sides of the upper portion of the container between the outer film 2 and the inner film 3 after filling the contents through the filling port. By bending this whole at the position of the lower bending portion 3a in the inner film 3, a double-fold package is obtained. In this state, the bent part 7 rises as the container upper part side, and the spout part 8 is located in a state where it protrudes toward one side of the container upper part in the folded package. This bi-fold package has a substantially triangular shape that opens downward, so that it can be satisfactorily satisfactorily, and can be displayed as a product in a stable state even when placed vertically on a display shelf such as a retail store.

  As described above, the two-fold packaging container 1 is composed of a pouch formed by fusing one or more films made of a laminate of two or more layers. This pouch can be folded in two at the position of the lower bent portion (bending line) 3a in the middle in the vertical direction. By bending one film at the position of the lower bent portion (bending planned line) 3a, the bent portion 7 that is convex is formed.

  A content outlet 8 is provided at one end of the bent portion 7. In the present application, the lower end position of the pouring path of the spout portion 8 is located above the position of the lower bent portion (bending line) 3a. Thereby, the spout part 8 can be cut easily and the effect that the contents are not easily spilled when the packaging container 1 is lifted is obtained.

  Further, at the lower part of the spout 8, a curved seal portion 9 that can be hooked on the bottle when the contents are poured toward the center of the pouch is provided at a position below the position of the planned bending line 3 a. Thereby, the content can be poured stably.

  In the two-fold wrapping container according to the present embodiment, the seal on the spout portion 8 side in the seal portion 4 at the upper bent portion 2a is used in order to improve the hand cutting property when the spout portion 8 is cut. A knob auxiliary part 16 is formed for increasing the width in the part height direction and increasing the area having the knob on the tip side of the spout part 8. Further, by reducing the width in the height direction of the seal portion other than the knob auxiliary portion 16 at the upper bent portion 2a, an acute notch is formed at the end of the knob auxiliary portion 16 opposite to the tip side of the spout portion. The part 17 is provided and it is set as the notch shape which is easy to form the starting end of a tear.

  The spout portion 8 is provided with an easy opening process line 18 for easy opening. The easy-open processing line 18 is provided so as to be inclined toward the protruding direction side of the spout part 8 with the notch part 17 as an upper end. Thus, since the easy-opening processing line 18 is provided so as to be inclined from the position of the notch portion 17 to the protruding direction side of the spout portion 8, it is excellent in hand cutting performance. Moreover, since the easy-open processing line 18 is slanted, the diameter of the pouring path becomes larger than that when the spout portion is cut straight in the vertical direction, and the diameter is sufficient to efficiently pour out the contents. Can be secured. Examples of the processing method of the easy-open processing line 18 include processing with a carbon dioxide laser or a metal blade.

  In addition, when a vertical tangent line (line a in FIG. 1) is drawn inside the seal line of the curved seal part (dent part) 9, it is preferable that the pouring path of the spout part 8 is outside the tangent line. Thereby, when the curved seal part (dent part) 9 is hooked on the bottle at the time of content extraction, the content can be easily extracted from the extraction path.

  Moreover, it is preferable that the upper side of the bent part 7 is formed so as to bend in the middle of the downward direction from the tip of the spout part 8 and toward the width direction of the pouch. Thereby, when cut | disconnecting the spout part 8 or carrying the packaging container 1, the effect which prevents that a content spills from a pouring path | route is acquired.
