Japanese Patent Laid-Open No. 2002-211588

  However, in the conventional package with a spout, the contents are extracted all at once when the contents are extracted from the spout. Therefore, it is very difficult to extract the contents in small portions, and even if only a part of the contents is to be extracted, the amount to be extracted is too small or conversely too large.

  Then, this invention is made | formed in view of the said conventional problem, and makes it a subject to provide the packaging body with a spout and the packaging bag with a spout which can divide and extract the contents.

The present invention has been made to solve the above problems, and the spout-equipped package according to the present invention has a spout on a bag body in which a peripheral portion is heat-sealed and a content enclosing region is formed inside thereof. In the attached spout-equipped packaging bag, a folding heat-sealing portion for folding the bag body along the outer shape is formed inside the peripheral edge portion so as to divide the content enclosing region. The fusion part is parallel to the thermal fusion part that seals the peripheral edge of the upper end, and extends from the thermal fusion part that seals the peripheral edge part of one side to the vicinity of the center of the bag body, and one side. the end peripheral portion has an inclined portion which inclined obliquely toward the distal end of the straight portion from the heat-sealing unit for sealing the other side edge periphery opposed to the heat-fused portion for bending the at the bag The spout is attached to the part, and the bag body is moved along the straight part of the heat-sealing part for bending. Characterized in that it is configured so that divided contents can be extracted from the spout by bending Ri.

Since the package with a spout having such a structure is configured to be bendable so that the enclosed contents are divided, the package with a spout can be folded when the contents are extracted from the spout. When the spout-equipped package is folded, the contents are divided at the fold. Therefore, only one side of the divided contents can be extracted from the spout. And since the bag body is bent, the other side of the divided contents will remain without being extracted from the spout. Moreover, in the packaging bag with a spout of this structure, the content is enclosed in the content sealing region of the bag body with a little bit and used as a packaging body with a spout. And when opening and extracting the contents, since the bending heat-sealing part is provided inside the peripheral part of a bag body, a bag body can be easily bent along the linear part . When the bag is folded, the content enclosed in the content enclosing region is divided at the crease, and only one side of the divided content can be extracted from the spout.

In addition, the spout-equipped packaging bag according to the present invention is characterized in that the bag body is provided with a display portion that indicates a folding position for folding the bag body and dividing the content enclosing region .

  In the spout-equipped packaging bag having such a configuration, the contents are enclosed in the contents-encapsulating region of the bag body with a small amount, and used as a spout-equipped packaging body. And when opening and extracting the contents, since the display part which shows a folding position is provided in the bag body, a bag body can be bent by using the folding position as a standard. When the bag body is folded, the content enclosed in the content enclosing region is divided at the fold line, and only one side of the divided content can be extracted from the spout.

The spout-equipped packaging bag according to the present invention is characterized in that a folding ruled line for folding the bag body to fold the bag body and divide the contents enclosing region is provided in the heat- sealed portion. .

  In the spout-equipped packaging bag having such a configuration, the contents are enclosed in the contents-encapsulating region of the bag body with a small amount, and used as a spout-equipped packaging body. And when opening and extracting the contents, since the folding ruled line is provided in the bag body, the bag body can be easily folded along the folding ruled line. When the bag is folded, the content enclosed in the content enclosing region is divided at the crease, and only one side of the divided content can be extracted from the spout.

  Thus, in the package with a spout according to the present invention, when the contents are extracted from the spout, the contents can be divided by folding, so only one side of the divided contents is removed from the spout. In addition to the conventional method of extracting all the contents at once as in the prior art, the contents can be extracted and used in small portions.

Hereinafter, an embodiment of a packaging body with a spout and a packaging bag with a spout according to the present invention will be described with reference to the drawings.

In the spout 4, the seal portion 41 is sandwiched between the front and rear wall portions 5 and 6 at a position between the straight line portion L of the bending heat fusion portion 10 and the second straight line display portion 12 a of the second display portion 12. It is attached to the bag body 3 by fusing, and the space G inside the bag body 3 communicates with the space outside. Specifically, first, the bag body 3 is formed by heat-sealing the peripheral edge portion excluding the portion where the spout 4 is attached. And the seal | sticker part 41 is inserted in that part, and it inserts | pinches between the front-and-rear both wall parts 5 and 6, and heat-seal | fuses. Thus, the spout 4 is attached to the bag 3 by forming the fourth heat-sealing portion 94 and heat-sealing. The upper part of the mouth part 42 is closed by a removable cap 43.

  When the contents F are injected from the spout 4 and sealed so that the spout-equipped packaging body 1 can be bent in the spout-equipped packaging bag 2 having the above-described configuration, the spout-equipped packaging body 1 as a product is formed. Specifically, as shown in FIG. 1 (A), the contents F are enclosed in a few eyes so that a certain amount of space G1 is formed at the top when the spouted packaging body 1 is placed in an upright state. In the present embodiment, the contents F are sealed so that the upper end of the contents F is in the vicinity of the straight line portion L of the bending heat-sealing portion 10 in the standing state, for example, about 200 cc to 500 cc.

  Thus, the spout-equipped packaging body 1 in which the contents F are enclosed in the spout-equipped packaging bag 2 is, as shown in FIG. 2, the second straight line display portion of the bag body 3 with the second straight line display portion 12a as a guide. The portion above 12a is folded downward, and the first locking piece 14a and the second locking piece 14b are engaged with each other and stored in a fixed state, and used as follows.

Next, as shown in FIG. 3 (A), the contents F are rotated upside down from the standing state to the side where the scale portion 13 of the space G inside the bag body 3 is provided. Move.

  Then, the bag 3 is folded along the straight line portion L of the bending heat-sealing portion 10 with the first straight line display portion 11a as a guide. When the bag body 3 is folded, the portions along the fold line C of the front and rear wall portions 5 and 6 approach each other and push the content F between them. The pushed content F is stored in a space G1 formed by enclosing the content F in the bag body 3 with a small amount. When further bent, the portions along the fold line C of both the front and rear wall portions 5 and 6 are brought into close contact with each other to form a band-shaped partition band 15. When the partition band 15 is formed, the space G inside the bag body 3 is partitioned with the boundary zone 15 as a boundary, and the content F is divided into sealed spaces G11 and G12 and enclosed. Since each partitioned space G11, G12 is partitioned by a partition band 15 formed along the fold line C, the divided contents F1, sealed in the partitioned spaces G11, G12, respectively. F2 never goes back and forth. In this way, only the divided contents F1 enclosed in the space G11 to which the spout 4 is attached can be extracted by removing the cap 43 that closes the mouth portion 42 of the spout 4. On the other hand, the divided contents F2 enclosed in the space G12 to which the spout 4 is not attached remain inside the bag body 3 without being extracted from the spout 4. In addition, since the scale part 13 is provided in this embodiment, the content F can be appropriately divided | segmented into a required quantity by making this into a standard. If the content F is not divided into the required amount, the bent state is released and the amount is adjusted. In the present embodiment, the amount is measured using the first scale 13a as a guide, for example, 70 cc.

  In the spout-equipped packaging body 1 as described above, the spout-equipped packaging body 1 is configured to be bendable so that the enclosed contents F are divided. That is, since the contents F are enclosed in the bag 3 in a little bit so as to form a space G1 in which the contents F that are pushed away by folding the bag 3 are stored, a part of the contents F is When extracting from the spout 4, the package 1 with a spout can be bent. When the spout-equipped package 1 is folded, the contents F are divided at the partition band 15 formed along the crease C. Therefore, the contents F can be divided by a simple operation with a very simple configuration, and the divided contents F1 sealed in the space G11 to which the spout 4 is attached are used as the mouth portion 42 of the spout 4. The content F2 enclosed in the other space G12 can be left in the bag 3 as it is. Therefore, in addition to the conventional method of extracting all the contents F at once as in the prior art, the contents F can be extracted and used in subdivisions F1 and F2.

  Further, since the bag body 3 is provided with the first display portion 11 indicating the folding position, when extracting the contents F into the subdivisions F1 and F2, the bag body 3 is folded with reference to the folding position. Can do.

  Further, the bending heat-sealing portion 10 is provided inside the peripheral edge portion to which the second heat-sealing portion 92 is sealed, and the outer shape on the lower side thereof is a substantially linear shape extending in the lateral direction of the bag body 3. It is the straight line part L. Therefore, when extracting the contents F into the subdivisions F1 and F2, the bag body 3 in which the contents F are enclosed can be easily bent along the straight line portion L. Further, since the bending heat-sealing portion 10 has a substantially triangular shape in plan view and is provided at a position substantially opposite to the spout 4, the distortion of the bag 3 caused by attaching the spout 4 can be corrected. , It can be in a standing posture with good posture.

  Furthermore, since the bag body 3 is provided with the locking means 14 and the second display portion 12 is provided above the folding heat-sealing portion 10, the spout-equipped packaging body 1 is stored. In the state where the bag body 3 is folded with the folding position indicated by the second display portion 12 as a guideline, the first locking piece 14a and the second locking piece 14b are engaged and the bent portion is locked. By fixing, the package 1 with a spout can be stored compactly. In addition, when it does not subdivide using the space G11, it can be used in this state.

In the present embodiment has described the case in which the first display unit 11 in the bag 3 is not limited thereto, without providing the first display unit 11, a ruled line folding for folding the bag 3 It may be provided. For example, it may be provided respectively ruled line for bending of the pair in the first Ninetsu fused portion 92 and the fourth heat fusion part 94. In this case, each of the bending for ruled line has a substantially linear shape extending in the lateral direction, it is found respectively below the spout 4. Further, each of the bending for ruled line is formed on the second heat fusion part 92 and the fourth heat fusion part 94 so as to be substantially the same position in the vertical direction. In this case, when extracting by the contents F in portions F1, F2, there is an advantage that the contents F can be folded easily along the ruled lines for folding the bag body 3 enclosed. As the folding ruled line, a ruled line that presses a heated blade can be used.
