Description

[Technical Field]

[0001] The present invention relates to a packaging bag and a packaging product. [Background technology]

[0002] BACKGROUND ART Conventionally, pouches and the like made by thermally bonding flexible resin film materials have been widely used as packaging bags for packaging various fluid contents. Various shapes and structures have been proposed for such packaging bags, and a packaging bag structured to be folded in half at the center to divide the content storage space into two is also known.

[0003] For example, the packaging bag (pouch) shown in Patent Document 1 below has two divided content storage spaces each filled with a two-component mixed composition, which are mixed and poured out at the time of use, and the communicating parts of each pouch (content storage space) are configured to communicate with a tapered pouring part via a folded part. Furthermore, the packaging bag (pouch) shown in Patent Document 2 below is free from pinholes and wrinkles caused by vibrations or dropping during transportation, and in order to make the entire refilling process easier, a branch (protruding piece) is formed extending from the front body part (front film), and an opening is formed in the branch by cutting off the tip of the branch, so that when opened, it folds in half to divide the content storage space into two.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-160176 [Patent Document 2] Japanese Patent Publication No. 2021-113084 Summary of the Invention [Problem to be solved by the invention]

[0005] When these packaging bags are opened, the contents are poured out from the two divided content storage spaces simultaneously, and no consideration is given to separating the two divided content storage spaces when opened and using each as two containers. For example, if multiple people want to share the contents of the above-mentioned known packaging bag, the contents cannot be shared by themselves and must be transferred to another container. It is also well known to connect multiple packaging bags together in advance and fill each content storage space with content, but since they must be separated before opening and each bag is opened independently, this does not meet the need for multiple people to share the contents stored in one content storage space.

[0006] Therefore, an object of the present invention is to provide a packaging bag and a packaging product that has a simple configuration, allows the content storage space of one packaging bag to be separated so that the contents can be shared, and allows the separated packaging bag to be used as two separate containers. [Means for solving the problem]

[0007] The packaging bag of the present invention has at least a front film and a back film, a sealing area formed on the outer periphery, and one internal storage space formed inside the sealing area, and the sealing area has a notch for cutting from the outer edge side, and the front film has a protruding piece that protrudes toward the outer surface of the internal storage space and contacts the internal storage space in a straight line, thereby solving the above problem. The packaging product of the present invention is a packaging product in which a fluid content is filled into a container and sealed, wherein the container is the packaging bag described above, and the filling volume of the content is 80% or less of the maximum filling volume of the internal storage space of the packaging bag, thereby solving the above problem. [Effects of the Invention]

[0008] According to the invention of claim 1, the front film has a protruding piece, so that when opening the package, the user can easily cut the protruding piece from the side seal area by pinching it with their fingers. Furthermore, by removing a portion of the protruding piece side of both the front and back films, including the protruding pieces, when cutting, it is possible to cut the content storage space that is divided into two by folding in half and handle it as two independent containers. Furthermore, by appropriately adjusting the distribution of the contents before opening, it is possible to share the contents including the distribution of the amount of the contents in the contents storage space divided into two after cutting.

[0009] According to the configuration described in claim 2, the edge of the sealed area on the internal storage space side is formed to be a straight line that overlaps with the fold line when the bag is folded in half with the protruding piece facing upward, making it easy to fold the bag in half along the fold line. According to the configuration described in claim 3, the notch is formed in a position symmetrical with respect to the fold line when the container is folded in half with the protruding piece facing upwards, so that two separate containers can be easily obtained with a single action. According to the configuration described in claim 4, the sealing area corresponding to the lower part when the container is folded in half with the protruding piece facing up is sealed between the front film and the back film via the bottom film, making it possible for both of the two independent containers obtained by cutting to be self-standing.

[0010] According to the configuration described in claim 5, the left-right width of the protruding piece at the fold line portion is formed smaller than the left-right width of the sealing area at the lower portion, so that when the two independent containers obtained by cutting are allowed to stand on their own, the upper portion becomes thinner, improving stability. According to the configuration of claim 6, the width of the outermost periphery of the sealing area in the left-right direction when the container is folded in half with the protruding piece facing up is formed to be smallest below the fold line when the container is folded in half with the protruding piece facing up, and the cut portion is formed above the position where the width of the outermost periphery of the sealing area in the left-right direction is smallest.As a result, the shape of the two independent containers obtained by cutting can be made to be wider at the opening side (sake bottle shape), making it possible to prevent the containers from falling when the user holds them in their hands when pouring, etc.

[0011] According to the invention of claim 7, the filling volume of the contents is 80% or less of the maximum filling volume of the internal storage space of the packaging bag, which makes it easy to move the contents between the content storage space that is divided into two by folding in half before cutting, and makes it easy to share the contents in any desired proportion.

[0013] A packaging bag 100 according to one embodiment of the present invention will be described below with reference to the drawings. As shown in Figures 1 to 5, the packaging bag 100 has two front films 110 and one back film 120, has a sealing area 140 (the hatched area in Figures 3 and 4) formed on the outer periphery, and has one internal storage space 150 on the inner periphery of the sealing area 140. As shown in FIG. 5 (which is exaggerated for the sake of explanation), the excess portions of the two front films 110 on the central side are sealed to form a protruding piece 111. The protruding piece 111 is provided so as to protrude toward the outer surface side of the internal storage space 150, and in this embodiment, it is in contact with the internal storage space 150 in a straight line, and is formed so that the edge of the sealed area of ​​the protruding piece 111 on the internal storage space 150 side forms a straight line that overlaps with the fold line 121 when the packaging bag 100 is folded in half with the protruding piece 111 facing upward.

[0014] The sealing area 140 has a notch 142 for cutting from the outer edge side, and the notch 142 is formed in a position symmetrical with respect to the fold line 121 when the packaging bag 100 is folded in half with the protruding piece 111 facing up, so that when folded in half, the positions overlap and the bag can be easily separated into two independent containers with a single action. Furthermore, as shown in Figure 5, the sealing area 140, which corresponds to the lower part when the protruding piece 111 is folded in half with the protruding piece 111 facing upward, is sealed between the front film 110 and the back film 120 via the bottom film 130, and the two separate containers are each configured as a so-called standing pouch with a gusseted portion at the bottom, making them able to stand on their own.

[0015] When the packaging bag 100 is folded in half with the protruding piece 111 facing upward, the width in the left-right direction of the outermost periphery of the sealing area 140 at the fold line 121 is made smaller than the width in the left-right direction of the sealing area 140 near the bottom, so that the tops of the two independent containers obtained by cutting become narrower, improving stability when they are allowed to stand on their own. In addition, when the protruding piece 111 is folded in half with the uppermost protruding piece 111 facing upward, the width of the outermost periphery of the sealing area 140 in the left-right direction is formed to be smallest below the fold line 121, and the cutout portion 142 is formed above the position where the width of the outermost periphery of the sealing area 140 in the left-right direction is smallest.

[0016] This allows the two independent containers obtained by cutting to have a shape that widens at the opening (like a sake bottle), which prevents the container from falling when the user holds it in their hand while pouring, and also improves the aesthetic appearance of the container. In this embodiment, the internal storage space 150 is formed with a constant width in the left-right direction above the position where the left-right width of the outermost periphery of the sealing area 140 is at its smallest, but the internal storage space 150 may also be shaped to widen toward the opening, similar to the outermost periphery of the sealing area 140, to prevent liquid from dripping from the opening during pouring, etc.

[0017] In this embodiment, by setting the filling amount of the contents to 80% or less of the maximum filling amount of the internal storage space 150 of the packaging bag 100, the amount of contents to be stored in each of the two divided internal storage spaces 150 can be adjusted over a wide range before folding the bag in half with the protruding piece 111 facing upward and cutting it from the cut portion 142. It is more preferable that the void ratio is 70% or less, since each of the two divided internal storage spaces 150 can be used as a container. Furthermore, if the void ratio is less than 50%, when the container is folded in half with the protruding piece 111 facing upward, all of the contents can be moved to one side and the other side can be left empty, and the contents can be cut with the contents moved to only one side without overflowing from the opening when the container is cut. Furthermore, by putting gas into the internal storage space 150 in addition to the contents, the amount of contents to be stored in each of the two divided internal storage spaces 150 may be adjusted more easily.

[0018] The shape of the outermost periphery of the sealing area 140 and the shape of the internal storage space 150 are not limited to those in the above embodiment, but can be formed in various shapes according to the practical or aesthetic needs of the user. Furthermore, in the above embodiment, when the case is folded in half with the protruding piece 111 facing upward, the sealing area 140 on the bottom portion is sealed between the front film 110 and the back film 120 via the bottom film 130, but the front film 110 and the back film 120 may be sealed directly without the bottom film 130, or the bottom film 130 may be extended to the sides, or a separate gusset film may be used to form gusset portions on the left and right sides in the width direction. In addition, in the above embodiment, the sealing area 140 has a cut portion 142 for cutting from the outer edge side, but it is also possible to have no cut portion 142 and allow the user to cut it from any position, or to apply an easy-to-open processing instead of the cut portion 142.

[0019] Furthermore, in the above embodiment, the protruding piece 111 is formed by sealing the excess central portions of the two front films 110, but it may also be formed by folding one front film so that it is doubled at the central portion and sealing it, or the front film may be shaped the same as the back film 120 and an independent member may be adhered to the fold line 121 portion to form the protruding piece 111. In addition, the actual fold line 121 may be formed by pre-creasing the fold during the manufacturing stage of the packaged product filled with the contents, or the actual fold line 121 may not exist until use, but may be formed when the product is folded in half with the protruding piece 111 facing upward.

[0020] In addition, the edge of the sealed area of ​​the protruding piece 111 on the side of the internal storage space 150 is formed to be a straight line that overlaps with the fold line 121 when the packaging bag 100 is folded in half with the protruding piece 111 facing upward, but it is also possible to form a space that is continuous with the internal storage space 150 above the fold line 121 when the packaging bag 100 is folded in half. Moreover, by providing a hole in the protruding piece 111, it may be possible to hang it on a hook or the like for display. Furthermore, a resealing mechanism may be provided on the internal storage space 150 side of the front and back films near the fold line 121 when the container is folded in half, so that one or both of the two separated independent containers can be resealed.
