An embodiment of the packaging container of the present invention will be described in detail with reference to the drawings. A packaging container 1 according to the present invention is configured as shown in FIGS. 1(a) and 1(b), for example. The packaging container 1 shown in FIG. 1(a) is made by superimposing two film-like members 2 and joining the four sides of the two film-like members 2 by a conventionally known method such as heat sealing. It is formed. Moreover, the packaging container 1 shown in FIG.1(b) is formed by folding the film-like member 2 of 1 sheet. The packaging container 1 is formed by folding a film-like member 2 to form folded ends 3, and joining three sides other than the folded ends 3 by a method such as heat sealing. In addition, the packaging container 1 according to the present invention is not limited to the above configuration, and may have other configurations as long as the contents can be accommodated in a sealed state. In addition, in the following explanation, for convenience of explanation, the packaging container 1 having the aspect shown in FIG.

The packaging container 1 is formed by joining square film-like members 2, and has an upper edge 4, a lower edge 5, a left edge 6, a right edge 7, and a partition portion 8, which are heat-sealed or the like. are joined and sealed by the method of In the drawing, the hatched portion is the seal portion 9 . The packaging container 1 includes a storage section 10 and a supply path 11 . The storage portion 10 is formed as a space portion formed so as to be able to store the content S having fluidity, and is surrounded by the lower edge 5, the left edge 6, the right edge 7 and the partition portion 8 of the seal portion 9. formed by The supply path 11 has one end portion 12 , the other end portion 13 , and a bent portion 14 formed between the one end portion 12 and the other end portion 13 . The one end portion 12 is formed so as to be continuous with the housing portion 10 , and the other end portion 13 is formed at a position separated from the one end portion 12 . The other end portion 13 also serves as a supply path forming portion 15 . A notch 16 is formed in the upper edge 4 at a position adjacent to the portion where the other end 13 is formed. A dotted line extending from the notch 16 is an expected tear line 17 . This notch 16 is formed in the shape of a cut, and when the user spills the contents S out of the packaging container 1, a part of the packaging container is torn from this notch 16 along a planned tear line 17. It is designed to be The expected tear line 17 straddles a part of the supply path 11, and when the user tears a part of the packaging container 1 from the notch 16, that is, from the upper edge 4 toward the right edge 7, the supply path 11 A part of the other end 13 is torn off to form a supply port 18 .

As shown in FIG. 2 , the supply path 11 has a communicating portion 19 that communicates with the housing portion 10 at one end portion 12 . In addition, the supply path 11 includes a communicating path 20 formed between the communicating portion 19 and the bent portion 14, and a guide path 21 formed between the bent portion 14 and the other end portion 13, The flow direction of the contents S in the communication path 20 is formed so as to be different from the flow direction of the contents S in the guide path 21 . That is, the content S that has flowed into the supply passage 11 from the storage portion 10 through the communication portion 19 first flows from the communication portion 19 into the communication passage 20 and passes through the bent portion 14 to change its flow direction, It is designed to flow to the guide path 21 .

The communication path 20 and the guide path 21 are preferably formed such that the width W1 of the communication path 20 is wider than the width W2 of the guide path 21. As shown in FIG. By forming the communication path 20 and the guide path 21 in this way, when the content S stored in the storage section 10 is transferred to the communication path 20 and the guide path 21, the amount of the content S flowing is can be adjusted by the user's operation. Further, by forming the guide path 21 so that the width W2 of the guide path 21 is narrower than the width W1 of the communication path 20 in this way, the content S stored in the storage section 10 passes through the communication path 20 and the guide path 21 In addition, when it is sealed as shown in FIG. It is possible to keep the contents S accommodated in the accommodating part 10 from flowing into the supply path 21. - 特許庁In this way, the content S housed in the housing portion 10 of the packaging container 1 is prevented from reaching the other end portion 13 of the supply passage 11 by keeping the housing portion 10 and the supply passage 11 in a sealed state. can be In addition, when the notch 16 is torn to tear a part of the packaging container 1 and the supply port 18 is opened, the contents S are pushed into the supply path 11, and the contents S are displaced. The content S in an amount proportional to the pressing force gradually flows out of the packaging container 1 . Therefore, according to this packaging container 1, it is possible to prevent the risk of staining fingers and clothes when the contents S are supplied from the supply port 18. FIG.

Examples of the film-like member 2 used for the packaging container 1 include olefin resins such as polyethylene and polypropylene, ethylene-vinyl alcohol copolymers, polyesters, polyamides, polyimides, and vinylidene chloride. In addition, the film-like member 2 can be formed of a material that allows the overlapping film-like members 2 to be joined together using a conventionally known method such as heat sealing, ultrasonic bonding, high-frequency joining, or the like. preferable. Such a film-like member 2 having a thickness within a range of, for example, 6 μm to 350 μm is arbitrarily selected and used. The film-like member 2 may be of a single layer or may be of multiple layers. When using a multi-layered one, the inner layer is made of the above material, and the outer layer is arbitrarily selected from the above materials or materials other than the above, such as Japanese paper. can be used as

Next, a method for manufacturing the packaging container 1 according to this embodiment will be described. The packaging container 1 is formed by stacking two film-like members 2 and joining them in order as described above. When joining, as shown in FIG. 3(a), the film-like members 2 are successively drawn out in the direction A in the drawing so that the film-like members 2 are positioned between the film-like members 2. , a nozzle 24 for supplying the contents S is arranged. Then, the film-like member 2 is fed out in the direction A, and when they are overlapped, they are successively sealed to form the seal portion 9, and the packaging container forming body 22 is formed. In the figure, hatched portions represent seal portions 9 where the film-like members 2 are joined together. As shown in FIG. 3(a), the packaging container forming body 22 is formed by successively sealing the lower edge 5, the left edge 6, and the right edge 7 to form the housing forming portion 23, and at the same time, the nozzle 24 is formed. The contents S are successively supplied from the container forming part 23, and the contents S are successively accommodated in the accommodation forming part 23. As shown in FIG.

As the packaging container forming body 22 advances sequentially in the direction A in FIG. 3(a), as shown in FIG. 3(b), the partition portion 8 is formed by sealing, and the supply path 11 is formed further above it. It is formed. At this time, the supply of the content S from the nozzle 24 is stopped at the timing when the position of the tip of the nozzle 24 reaches the communicating portion 19 from the accommodation portion 10 formed by the film-like member 2 being paid out. On the other hand, the film-like member 2 is delivered in sequence, and sealing is performed in sequence while the supply path 11 is being formed, so that the packaging container 1 in which the content S is stored in the storage portion 10 is formed. By forming the packaging container 1 in this way, the content S is accommodated in the accommodating portion 10, and the film-like member 2 sticks to the portion where the supply path 11 is formed by surface tension. In addition, when in such a sealed state, the internal pressure in the storage portion 10 and the supply path 11 does not escape to the outside of the packaging container 1, so even if the user presses the storage portion 10, the pressing operation Therefore, the content S can be prevented from moving from the container 10 to the supply path 11 . When forming the supply path 11, it is preferable to prevent the presence of air or the like in the supply path 11. For this purpose, the film-like member 2 located in the supply path 11 is stuck to the supply path 11 by surface tension. It is preferable that Therefore, when manufacturing the packaging container 1, when sealing the portion forming the supply path 11 in forming the sealing portion 9, for example, the film-like members 2 are in contact with each other separately from the member for sealing. A pressing member or the like for pressing the film-like member 2 against each other may be arranged to press the film-like members 2 against each other. In this case, as the pressing member, a conventionally known member may be arbitrarily selected and used, and it is preferable to use, for example, a member formed of a rubber material or the like.

Then, as shown in FIG. 3(c), when the sealed packaging container 1 is formed with the content S stored in the storage portion 10, the already formed packaging container 1 is newly formed by sealing. The portion between the packaging container forming body 22 formed as the packaging container 1 (the location indicated by the dashed line in FIG. 3(b)) is cut. By such order, the packaging container 1 in which the content S is sealed is formed.

Next, in the packaging container 1 according to the present invention, the effects of supplying the contents S to the outside of the packaging container 1 will be described. FIG. 4(a) shows the packaging container 1 in which the container 10 and the supply path 11 are closed. In the packaging container 1 at this time, the content S is accommodated in the accommodation portion 10 as described above, and the content S may be present in the supply path 11 in a state in which the film-like members 2 are stuck to each other. configured to prevent Here, the state in which the content S cannot exist means that the content S does not exist in the supply path 11 at all, or the amount of the content S that exists in the supply path 11 even if the content S exists. is extremely small. As described above, since the packaging container 1 is in a state in which both the storage part 10 and the supply path 11 are sealed, even if the user presses the storage part 10 from the outside of the packaging container 1, the storage part 10 does not contain the packaging container. The content S that has been loaded stays in the container 10 without moving to the supply path 11 .

Next, as shown in FIG. 4(b), when the user tears from the notch 16 and tears part of the packaging container 1 along the planned tear line 17, the other end 13 of the supply path 11 is torn. Then, the supply port 18 is opened. When the supply port 18 is opened in this way, the sealed state inside the accommodating portion 10 and the supply path 11 is released, and the film-like members 2 formed so as to stick to each other at the location where the supply path 11 is formed are separated. The supply path 11 is formed by peeling off, and the contents S can flow out. When the supply port 18 is opened in this manner, the contents S stored in the storage portion 10 are sequentially transferred to the supply path 11 only when the user presses the storage portion 10, and the supply port 18 is supplied to the outside of the packaging container 1 from.

At this time, since the packaging container 1 is formed so that the width W2 of the guide path 21 is narrower than the width W1 of the communication path 20 in the supply path 11, the user presses the storage portion 10 to store the package. When the internal pressure of the part 10 is increased, the content S is transferred to the supply channel 11 accordingly. As described above, since the supply path 11 is formed so that the width W2 of the guide path 21 is narrower than the width W1 of the communication path 20, the resistance of the contents S when passing through the guide path 21 is Greater than the resistance it passes through. Therefore, when the user does not press the container 10, the resistance of the content S passing through the guide path 21 is greater than the force for the content S to flow. It is possible to prevent the material S from flowing out from the supply port 18 . In addition, by reducing the amount of the content S supplied from the supply port 18 in this way, the amount of the content S supplied from the supply port 18 is adjusted by the amount of pressing of the container 10 by the user. be able to Therefore, it is possible to reduce the risk of the content S unexpectedly spilling out of the supply port 18 or staining fingers or clothes.

As described above, according to the packaging container 1 of the present invention, the amount of the contents S supplied from the supply port 18 can be adjusted by the user pressing the container 10, and the user can Unintentional outflow of the content S can be prevented when the storage portion 10 is not pressed. Therefore, it is possible to prevent the content S from suddenly flowing out of the supply port 18 at the same time as the supply port 18 is opened by tearing the notch 16 and staining the user's fingers and clothes. Only the amount required by the user can flow out from the supply port 18 . In general, the amount of the content S required by the user varies from person to person and also changes depending on usage conditions. On the other hand, if the contents S flow out all at once when the supply port 18 is opened, handling of the contents S that flowed out more than necessary becomes complicated, and there is a risk of staining the user's fingers and clothes. In addition, the notch 16 is carefully torn to open the supply port 18 so that the user does not get his fingers or clothes dirty, which causes the user to be extra cautious. . In this regard, according to the packaging container 1 according to the present invention, the amount of contents S required by the user can be discharged from the supply port 18, and the force of the contents S flowing out from the supply port 18 is also reduced. The user can arbitrarily adjust the outflow direction of the content S flowing out from the supply port 18 . Therefore, according to the packaging container 1 of the present invention, the contents S can flow out with a simple operation without worrying about the user, and the handling of the packaging container 1 can be greatly improved. become.

Although it is preferable to form it so as to be narrow, when a plurality of bent portions such as the first bent portion 14a to the third bent portion 14c are formed as in the packaging container 1 according to the present modification, the communicating portion The width W3 of 19 (communication path 20) and the width W4 of guide path 32 may be the same. In the case of the packaging container 1 of this modified example, since the bent portion 14 is provided over a plurality of locations such as the first bent portion 14a, the second bent portion 14b, and the third bent portion 14c, the contents S flow in a plurality of directions. change over time. Therefore, even if the width W3 and the width W4 are formed to be approximately the same, the contents S do not flow out all at once when the other end 13 is opened and the supply port 18 is opened. It is possible to adjust the supply of the contents S by pressing the containing portion 10 by the .

FIG. 7 shows another modification of the packaging container 1 according to the invention. Also in the case of the packaging container 1 of this example, since a plurality of bent portions 14 are formed in the same manner as described above, it is possible for the user to easily adjust the outflow of the contents S. .
