Description

  The present invention relates to a flexible container such as a pouch container or a soft packaging material container for hermetically wrapping contents such as liquid, and more specifically, a fastener used for a flexible container, a flexible container, And it relates to a flexible container provided with a fastener.

  Conventionally, a flexible container such as a pouch container for hermetically wrapping contents such as a liquid is known, and there is a document disclosing this (see Patent Document 1).

  For example, in Patent Document 1, a packaging bag is divided into a measuring room and a main room, and a spout (outlet) is provided in the measuring room so that a predetermined amount of contents measured in the measuring room can be poured out from the spout. A configuration is disclosed.

JP2013-056698A

  In recent years, flexible containers such as pouch containers and soft packaging containers have been increasingly used from the viewpoint of environmental and resource saving. For example, it is an application for hermetically wrapping various liquid products for seasoning food and drink such as concentrated fruit juice products, concentrated beverage products, various syrup products, and soy sauce provided to homes and stores.

  Flexible containers are also widely used for household consumer products such as liquid detergents and softeners, and cosmetic packaging. In addition, it is widely used in factories, research facilities, universities, etc., for the purpose of appropriately dispensing hermetically sealed raw materials and chemicals.

  Thus, the flexible container has various uses, and further expansion of the use is expected. In this regard, in the technique disclosed in Patent Document 1, since one weighing chamber is provided, it is possible to pour out a predetermined amount of contents one by one, which is suitable for applications requiring weighing. It becomes. When the measurement is performed, the passage through which the contents are circulated between the main chamber and the measurement chamber is closed by bending the container, thereby preventing the backflow of the contents from the measurement chamber to the main chamber.

  However, in the configuration in which the passage is closed by bending the container, it is necessary to continue to bend the container even during the pouring operation, and it can be said that the operability is not excellent. In other words, for example, (1) the cap that closes the spout should be opened while maintaining the folded state, or (2) the spout is turned in the opposite direction and the pouring operation is difficult. I am concerned that it will occur. Furthermore, (3) the folded measuring chamber overlaps with the main chamber, so the cap is difficult to open. (4) In the folded state, the main chamber exists around the spout and gets in the way and inserts the spout into the container. (5) The contents poured out from the spout touch the film surface of the main chamber and the film surface becomes dirty. (6) The film surface touches the film surface of the main chamber around the spout. There is also concern that it will become dirty.

  Furthermore, since it is bent by a human manual operation, there is a concern that a deviation may occur in the bent portion every time, and there is a concern that the accuracy of measurement cannot be kept high.

  In addition, in a series of dispensing operations, the user must always be careful not to cause a backflow from the measuring room to the main room, which causes stress to the user. .

  In view of the above points, the present invention proposes a novel technique that makes it possible to form an internal space for weighing without bending a container.

  On the other hand, in a configuration in which there is only one weighing chamber with a prescribed capacity as in the conventional case, when a large amount of content is to be poured out, multiple dispensing operations are forced, and the operation is complicated. It will be a thing. In addition, for example, it may be necessary to calculate the number of times of dispensing, such as “Need to dispense 4 times”, or situations such as “forgetting the number of times of dispensing” during the dispensing operation may occur. Concerned.

  Furthermore, if the number of times of dispensing is multiple times, the contents that were poured out for the first time will be exposed to the outside air for a long time, and it is assumed that the composition will differ from the contents that were poured out later. Is done. In particular, when handling a liquid that easily undergoes changes such as vaporization and oxidation, a situation may arise in which it is not suitable to pour out in multiple batches.

  In addition, since there is only one weighing room with the specified capacity, if the user wants to dispense a smaller amount of contents, a weighing using the weighing room is impossible. It will be necessary to measure using means.

  As can be seen from the above, the conventional flexible container having one weighing chamber cannot cope with both small quantity / large quantity weighing, and a variety of users who are expected to expand further. It will not be able to meet the needs.

  Therefore, in view of the above problems, the present invention proposes a novel technique for realizing more various weighings for a flexible container.

  As described in detail below, as shown in FIGS. 1 and 2, the flexible container 1 is configured as a bag-like airtight container by sealing, for example, the peripheral edge 3a of the film 3 superimposed on two sheets. In the present embodiment, the measuring unit 21 has a narrowing width for the purpose of mainly measuring, and the storing unit 22 has a large width and ensures a large capacity mainly for the purpose of storing a large amount of the contents 2. .

  The measuring section 21 is provided with a spout 4, and the contents 2 can be poured out from the spout 4. The spout 4 can be composed of a resin cylindrical member. A cap 6 is detachably provided at the spout 4, and the contents 2 can be poured out from the spout 4 by removing the cap 6, and the contents 2 can be sealed by attaching the cap 6. It can be saved with. In addition, it is good also as providing the some spout 4 besides the structure provided with the one spout 4.

  A fastener 5 is attached to the measuring unit 21 of the flexible container 1. As shown in FIGS. 3 (A) and 3 (B), the fastener 5 of the present embodiment has two rod-like holding members 56 and 57 for holding the flexible container 1. , 57 are connected at one end so as to be rotatable by a rotating portion 58, and can be engaged at the other end by a holding state maintaining mechanism 59. The clamping state maintaining mechanism 59 is configured by a locking member 59 a that rises from one clamping member 56 and can be engaged / disengaged with the tip of the other clamping member 57.

  In addition, about the clamping members 56 and 57, it is set as the structure which clamps the flexible container 1 by rotating one end and connecting the other end like this Example, for example, the edge parts of two clamping members The flexible container 1 is configured to be integrated by fitting, or a groove is formed in one holding member, and the flexible container 1 is inserted from the side into the groove. A configuration in which 1 is sandwiched is also conceivable, and the specific configuration is not particularly limited. It is also conceivable that the holding state maintaining mechanism 59 is configured by a configuration in which the holding state maintaining mechanism 59 is omitted or a string that binds two holding members.

  As shown in FIGS. 3 (A) and 3 (B), one clamping member 56 is formed with a clamping part 56a formed of a flat surface. The other clamping member 57 is formed with a clamping part 57a constituted by a flat surface and a non-clamping part 57b having a concave groove shape formed by cutting out a part of the clamping part 57a. The sandwiching portions 56a and 57a of the sandwiching members 56 and 57 are opposed to each other. As shown in FIG. 2, in the state where the flexible container 1 is sandwiched, the flexible container 1 has a non-nip portion 57b. A linear pressure-bonding portion 51 is formed at the removed portion. By forming the crimping part 51, the measuring part 21 is partitioned inside, and an internal space 21n having a predetermined capacity is formed.

  Further, the flexible container 1 is not sandwiched at the portion of the non-clamping portion 57b of the clamping member 57, and a portion where the crimping portion 51 is not formed in the flexible container 1 is formed as shown in FIG. In the part where the crimping part 51 is not formed, a communication path 41 for communicating the measuring part 21 and the accommodating part 22 is formed.

  A switching mechanism 55 is provided at the position of the non-clamping portion 57 b of the clamping member 57.

Closed. In this way, by closing the communication path 41, the crimping part 54 (see FIG. 2) is formed also in the non-clamping part 57b.

  As shown in FIG. 5, weighing marks 21 a, 21 b, and 21 c are provided on the surface of the weighing unit 21 of the flexible container 1. The weighing mark is composed of lines (lines) in which the dots are arranged in the horizontal direction in the weighing unit 21 as in the present embodiment, or is a continuous line, or uses various symbols such as arrows, 50 ml , 100 ml, etc. may be used to describe the capacity, or a combination of these may be used.

  Then, by placing the fastener 5 in accordance with the measurement marks 21a, 21b, 21c, desired measurement can be performed. For example, when the fastener 5 is used in accordance with the weighing mark 21a, a 50 ml internal space 21n (see also FIG. 2) is formed in the weighing section 21 on the side close to the spout 4, and the contents are accurately accurate by 50 ml. Can be weighed.

In this way, the crimping part 51 is formed as shown in FIG. 2, and the volume of the internal space 21n partitioned by the crimping part 51 can be matched with the capacity to be measured.

  Next, as shown in FIG. 6, after the housing portion 22 is pushed by hand to complete the pouring of the contents into the internal space 21 n through the communication path, the switching mechanism 55 is operated while maintaining the state where the housing portion 22 is pushed by hand. The communication path is closed by setting the closed state. Here, the state in which the accommodating portion 22 is pushed by hand is maintained in order to prevent the backflow of contents from the internal space 21n to the accommodating portion 22.

  Then, as shown in FIG. 6, by setting the switching mechanism 55 to the “closed state”, the internal space 21n is closed and the measurement can be completed. Subsequently, the contents weighed accurately can be poured out from the spout 4 by removing the cap 6.

  Moreover, other embodiment is also considered about the fastener 5 demonstrated above. For example, in the fastener 5A shown in FIGS. 7A and 7B, the switching of the open / close state of the communication passage 41 (FIG. 2) is performed by sliding the pressing portion 55m of the switching mechanism 55A in the lateral direction and switching the position.

  In addition, in the fastener 5B shown in FIGS. 8A and 8B, the position of the communication path 41 (FIG. 2) is changed by switching the position by sliding the pressing portion 55n of the switching mechanism 55B in the vertical direction with the operating rod 55v. The open / close state is switched. In this configuration, an urging mechanism 55w having an elastic body such as a spring is provided, and the pressing portion 55n is attached in the direction in which the communication path 41 (FIG. 2) closes (the direction in which the switching mechanism 55B is in the “closed state”). It is also conceivable to generate a load F2 (a load that pushes up the operating rod 55v and moves the pressing portion 55n downward).

  Furthermore, as shown in FIG. 9, like the fastener 5C, a set of the non-clamping portion 57b and the switching mechanism 55 is provided at a plurality of locations (two locations in this embodiment), so that the communication path 41 (FIG. 2) may be configured at a plurality of locations. In this case, since the number of the communication paths 41 increases, the structure which can move a lot of contents from the accommodating part 22 to the measurement part 21 simultaneously is implement | achieved.

  In addition, in the above embodiment, the switching mechanism 55 (FIG. 1) is provided. However, the switching mechanism 55 may not be provided. That is, it is possible to insert the finger into the portion of the non-clamping portion 57b shown in FIG. 3 and to press the flexible container 1 directly with the finger, thereby forming the crimping portion 54 (see FIG. 2). it can.
