Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the attached drawings. In addition, in this specification and the drawings, for constituent elements that have substantially the same functional configuration, the same symbols are used to omit repeated descriptions.

(First Embodiment) Fig. 1 is a top view of a bag with a chain strap according to the first embodiment of the present invention. 2 and 3 are cross-sectional views taken along lines II-II and III-III in FIG. 1. As shown in the figure, the bag with a zipper strap 100 includes a bag body 110 having a first side 111A and a second side 111B facing each other, and a bag body 110 disposed between the first side 111A and the second side 111B. Zipper tape 120, and film 130. The elongated zipper tape 120 joins at least a part of the width direction to the first surface 111A and the second surface 111B over the entire length, thereby defining the gap formed between the first surface 111A and the second surface 111B of the bag body 110 One side of the storage space SP.

The bag body 110 is formed of, for example, a single-layer or multiple-layer thermoplastic resin film. More specifically, the thermoplastic resin may be low density polyethylene (LDPE), linear low density polyethylene (LLDPE), or polypropylene (PP). PP can be homopolypropylene (HPP), random polypropylene (RPP), or block polypropylene (BPP). When the bag body 110 is formed of a multilayer film, biaxially stretched polypropylene (OPP), biaxially stretched polyethylene terephthalate (OPET), or biaxially stretched nylon (ONy) can be used as the surface substrate . These resins are not limited to fossil fuel-derived resins, and can be bioplastics that consider the environment, and a mixture of fossil fuel-derived resins and bioplastics can also be used. In addition, the film forming the bag body 110 may also include a layer of an inorganic material formed by aluminum vapor deposition or a laminate of aluminum foil.

In addition, in this embodiment, the bag body 110 is formed by joining two films in the bottom seal portion 112 and the side seal portion 113 to each other, but in other embodiments, the bag body 110 is formed by attaching one film to the side seal portion 113. The corresponding part is folded back to form the bag body 110. Moreover, the part corresponding to the bottom seal part 112 or the side seal part 113 of the example of FIG. 1 may be formed into the part which folded the film inward, so-called a gusset. In this case, the gussets may be formed by the same film as the first surface 111A or the second surface 111B, or may be formed by different films. In addition, the bag with a zipper strap 100 may also be a self-supporting bag that can be placed upright by forming a gusset at the bottom.

In addition, in this embodiment, the bottom seal portion 112 and the side seal portion 113 are formed. On the other hand, the opening 101 of the bag 100 with a chain strap is formed because the top seal portion is not formed. However, in another embodiment, In addition to forming the bottom seal portion 112 and the side seal portion 113, a top seal portion can also be formed, and an opening can be formed in the bag 100 with the zipper strap afterwards by cutting the top seal portion and the zipper tape 120 101. In yet another embodiment, a bag with a zipper strap may be provided in a state where the bottom seal 112 is not formed, that is, the storage space SP is not sealed on the side opposite to the zipper strap 120. In this case, the bottom seal 112 is formed after filling the storage space SP with content. In addition, the present invention can be applied to bags with various configurations of known chains attached.

The zipper tape 120 is, for example, a long member formed by extrusion molding of polyolefin resin, and is arranged between the first surface 111A and the second surface 111B of the bag body 110 to define the storage space SP Aside. The zipper tape 120 is formed of, for example, a polyolefin-based resin. More specifically, the zipper tape 120 may be formed of low density polyethylene (LDPE), linear low density polyethylene (LLDPE), or polypropylene (PP). PP can be homopolypropylene (HPP), random polypropylene (RPP), or block polypropylene (BPP). These resins are not limited to fossil fuel-derived resins, and can be bioplastics that consider the environment, and a mixture of fossil fuel-derived resins and bioplastics can also be used. It is also possible to add well-known additives, such as stabilizers, antioxidants, lubricants, antistatic agents, or coloring agents, to the material of the zipper belt 120 as required.

As shown in Figures 2 and 3, in this embodiment, the cross-sectional shape of the zipper tape 120 includes first engaging portions 121A, 121B, and a second engaging portion that can be engaged with the first engaging portions 121A, 121B 122A, 122B, the first base 123, and the second base 124. The first base 123 includes a first flange 123A formed on the side of the storage space SP (the opening 101 side) than the root 121R of the first engaging portions 121A, 121B, and a first flange 123A formed on the side opposite to the first flange 123A. Two flanges 123B are joined to the first surface 111A of the bag body 110 at both the first flange 123A and the second flange 123B. The second base 124 includes a third flange 124A formed on the side of the storage space SP than the root 122R of the second engaging portions 122A and 122B, and is joined to the second surface 111B of the bag body 110 only at the third flange 124A . As in the example described later, the second base 124 may further include a fourth flange formed on the side opposite to the third flange 124A, but in this case, the fourth flange is not joined to the second surface 111B.

As described above, in this embodiment, the opening 101 side of the second base 124 of the first base 123 and the second base 124 of the zipper tape 120 is not joined to the bag body 110. Thereby, even if one wants to grasp the first surface 111A and the second surface 111B of the bag body 110 on the side of the opening 101 to open the bag 100 with the zipper strap, it is difficult to connect the first engaging portions 121A, 121B and the second card The opening direction of the joints 122A and 122B exerts a force. As will be described later, except for the part where the film 130 is inserted, the bag 100 with the zipper is difficult to open.

In addition, regarding the engaging portion formed on the zipper tape 120, in the example shown in the figure, the first engaging portion 121A is a female mold, the second engaging portion 122A is a male mold, and the first engaging portion 121B and the second card The engaging portion 122B is a hook mold, but it is not limited to the example shown in the figure, and a shape that combines the engaging portion of various known zipper belts such as a claw shape, a hook shape, or a knob shape can also be used. In addition, although two pairs of engaging parts are shown in the example shown in the figure, there may be one pair of engaging parts, or three or more pairs. Also, in the example shown in the figure, although the engaging parts (male mold, female mold, and hook mold) of different shapes are arranged one by one, two or more pairs of engaging parts of the same shape (such as male mold and female mold) can also be arranged. . In any case, by not joining the opening side of one of the bases of the zipper belt to the film, the bag with the zipper belt can be made difficult to open.

The film 130 is arranged in a partial section in the longitudinal direction of the zipper tape 120 as shown in FIG. 1. Furthermore, as shown in FIG. 3, the film 130 is joined to the second surface 111B of the bag body 110 in this embodiment. The film 130 extends along the width direction of the zipper tape 120 and is inserted between the first engaging portions 121A, 121B and the second engaging portions 122A, 122B. In the example shown in the figure, the first engaging portions 121A, 121B and the second engaging portions 122A, 122B sandwich the film 130 therebetween and engage. Even if the first engaging portions 121A, 121B are engaged with the second engaging portions 122A, 122B, the film 130 is sandwiched between them, and the film 130 is pulled apart from the first engaging portions 121A, 121B. The pressing and engaging of the second engaging portions 122A and 122B are released, so that the bag 100 with the zipper can be opened. In the example shown in the figure, although the film 130 is arranged in one section in the longitudinal direction of the zipper tape 120, the film 130 may be arranged in a plurality of sections, respectively.

The film 130 is made of a flexible resin material, such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon (Ny), or these composite materials (composite film) )form. In particular, PE has flexibility, and it is preferable to use various thicknesses of pre-made films according to the structure of the engaging portion. In addition, since the sealing layer of the bag body 110 to which the film 130 is joined mostly contains PE, it is also preferable to use PE from this point. These resins are not limited to fossil fuel-derived resins, and can be bioplastics that consider the environment, and a mixture of fossil fuel-derived resins and bioplastics can also be used.

As described above, when the film 130 is clamped between the first engaging portions 121A, 121B and the second engaging portions 122A, 122B and engaged, the film 130 preferably has a shape in the width direction of the zipper tape 120 It can cover the length of the first engaging portion 121A, 121B or the second engaging portion 122A, 122B along the cross-sectional shape (for example, longer than the length from the position where the film 130 is joined to the second surface 111B to the side of the storage space SP of the zipper tape 120) The distance between the ends). In the above case, the thickness of the film 130 is preferably 10 μm or more and 80 μm or less, more preferably 15 μm or more and 65 μm or less, and particularly preferably 20 μm or more and 50 μm or less.

For example, in the case of using the bag 100 with a zipper strap to prevent children from opening, it may be better not to be unable to open the bag once the bag with a zipper strap is sealed, but for those who know the method of opening for protection. The situation can be opened. In this embodiment, although it is difficult to open the zipper-attached bag 100 as a whole as described above, it can be opened if the part where the film 130 is arranged is set as the starting point. Therefore, it is possible to realize a state in which the protector who knows the existence of the film 130 can open the seal, but it is difficult for children who do not know it.

In the case of this kind of use, if the film 130 is arranged near the center of the zipper tape 120 in the longitudinal direction, there is a possibility of accidentally opening the bag 100 with the zipper tape, so the example shown in FIG. 1 is preferred. Generally, the film 130 is arranged near the end of the zipper tape 120 in the longitudinal direction. Also, for example, when a finger is inserted into the bag 100 with the zipper tape from the part where the film 130 is placed, the width of the film 130 (that is, the length of the section in the longitudinal direction of the zipper tape 120 where the film 130 is placed) Preferably it is 10 mm or more. In order to imply the position where the seal can be opened, the film 130 can also be colored in a different color from either the bag body 110 or the zipper tape 120. For example, when the bag body 110 or the zipper tape 120 is transparent, the color of the film 130 is not particularly limited.

Fig. 4 is a diagram showing another example of the cross-sectional view shown in Fig. 3. As shown in the example shown in FIG. 4, in a partial section in the longitudinal direction of the zipper tape 120 where the film 130 is disposed, the first engaging portions 121A, 121B and the second engaging portions 122A, 122B may not be engaged. In this case, the bag 100 with the zipper can be opened by setting the part where the film 130 is arranged as the starting point. In this case, the thickness of the film 130 can also be thicker than the example described above with reference to FIG. 3.

Fig. 5 is a diagram showing the state in which the film is drawn out from between the engaging portions in the example shown in Fig. 3 or Fig. 4. When the film 130 is pulled out from between the first engaging portions 121A, 121B and the second engaging portions 122A, 122B and pulled out to the side opposite to the zipper tape 120 (the opening 101 side in the example shown in the figure) It is difficult to open the bag 100 with the zipper belt over the entire length of the zipper belt 120 including the part where the film 130 is arranged. For example, when the protector does not need to open the bag 100 with the zipper, the film 130 may be drawn out from between the first engaging portions 121A, 121B and the second engaging portions 122A, 122B as shown in FIG. 5. In this way, the film 130 can be inserted between the first engaging portions 121A, 121B and the second engaging portions 122A, 122B, or the first engaging portions 121A, 121B and the second engaging portion 122A may not be inserted all the time. , 122B.

Fig. 6 is a cross-sectional view of a bag attached with a chain strap according to a modification of the first embodiment of the present invention. In the example shown in the figure, the second base 124 further includes a fourth flange 124B formed on the side opposite to the third flange 124A, and is joined to the bag body 110 at both the third flange 124A and the fourth flange 124B The second side 111B. In this case, unlike the above example, if the first surface 111A and the second surface 111B are grasped on the side of the opening 101, the first engaging portions 121A, 121B and the second engaging portions 122A, 122B can be pulled apart. The direction of applying force. In this case, for example, the engagement strength between the first engagement portions 121A, 121B and the second engagement portions 122A, 122B is set to a level that is not easy to open with the simple operation described above, specifically 26 N /50 mm or more, preferably 30 N/50 mm or more, more preferably 40 N/50 mm or more.

In this case, it is difficult to open the bag 100 with the chain strap outside of the area where the film 130 is inserted due to the excessively strong engagement strength. On the other hand, in the section where the film 130 is inserted, as shown in the example shown in FIG. 4, the first engaging portions 121A, 121B and the second engaging portions 122A, 122B are not engaged, or as shown in FIG. 3 For example, even if the first engaging portions 121A, 121B are engaged with the second engaging portions 122A, 122B, the engaging strength is weakened by the degree equivalent to the intermediate film 130, and the bag 100 with the zipper tape can be opened.

Here, for example, a digital dynamometer (manufactured by Imada) can be used to measure the engagement strength as follows. First, the first base portion 123 and the second base portion 124 are held at a distance of 2 mm from the engaging portion of the zipper tape cut to 50 mm in the longitudinal direction. Next, with the first base 123 fixed, measure the strength of the second base 124 until the first engagement portion 121A, 121B and the second engagement portion 122A, 122B are released, and the maximum load is measured. The result is set as the engagement strength. When the length in the longitudinal direction is less than 50 mm, if the length is set to X mm, the measurement result N/X mm can be converted to N/50 mm by multiplying the measurement result N/X mm by 50/X. In addition, when the opening 101 side of the example shown in FIGS. 2 to 5 has no flange on the second base 124, after joining the zipper tape to the bag body 110, place the bag body 110 along the long side The direction was cut to 50 mm, and the second base 124 was replaced with a portion 2 mm from the engagement portion to hold the second surface 111B of the bag body 110, and the same measurement as above was performed.

(Second Embodiment) Fig. 7 is a cross-sectional view of a bag with a chain strap in the second embodiment of the present invention. In this embodiment, the second base portion 124 of the zipper tape 120 further includes a fourth flange 124B formed on the side opposite to the third flange 124A of the second engaging portions 122A and 122B. In the example shown in the figure, the fourth flange 124B is not joined to the second surface 111B of the bag body 110. In this embodiment, the film 130 is joined to the fourth flange 124B. In addition, since the configuration of this embodiment is the same as that of the above-mentioned first embodiment with respect to the points other than these, repetitive descriptions are omitted.

In this embodiment, the second flange 124B of the second base 124 is not joined to the second surface 111B of the bag body 110, and the first surface 111A and the second surface 111B of the bag body 110 are grasped on the opening 101 side. When opening the bag 100 with zipper strap, it is also difficult to apply force in the direction in which the first engaging parts 121A, 121B and the second engaging parts 122A, 122B are pulled apart. Except for the section where the film 130 is inserted, the zipper is attached. The bag 100 is difficult to open. In the section where the film 130 is inserted, as described in the first embodiment, the first engaging portions 121A, 121B and the second engaging portions 122A, 122B are not engaged, or even if the first engaging portions 121A, 121B and the second card The engagement of the joints 122A and 122B also weakens the engagement strength to the extent that the film 130 is interposed, so the bag 100 with the zipper can be opened.

In addition, in the case of this embodiment, if the first surface 111A of the bag body 110 and the fourth flange 124B of the second base portion 124 are grasped on the side of the opening 101, the first engaging portions 121A, 121B and Force is applied in the direction in which the second engaging portions 122A and 122B are pulled apart. When it is assumed that the fourth flange 124B is grasped, as in the example described above with reference to FIG. 6, it is only necessary to set the engagement strength between the first engaging portions 121A, 121B and the second engaging portions 122A, 122B. To the extent that it is not easy to open the package with a simple action, specifically, it is 26 N/50 mm or more, preferably 30 N/50 mm or more, and more preferably 40 N/50 mm or more. In this case, as described with reference to FIG. 6, the bag 100 with the zipper tape can be opened in the section where the film 130 is inserted.

Fig. 8 is a cross-sectional view of a bag with a chain strap in a first modification of the second embodiment of the present invention. In the example shown in the figure, the film 130 includes an extension portion 131 that extends to the opening 101 side (the side opposite to the storage space SP) with respect to the second base portion 124 including the fourth flange 124B. In this case, in the area where the film 130 is inserted, the first surface 111A and the extension portion 131 of the bag body 110 are grasped by the opening 101 side, and the first engaging portions 121A, 121B and the second engaging portions 121A and 121B can be engaged with each other. Force is applied in the direction in which the parts 122A and 122B are pulled apart. For example, when the size of the fourth flange 124B in the width direction of the zipper tape 120 is small, there is a possibility that it is not easy to grasp the fourth flange 124B even if the protector of the unsealing method is known. In this case, by providing the extension 131, the difficulty of opening the interval of the interposing film 130 can be adjusted.

Fig. 9 is a cross-sectional view of a bag with a chain strap in a second modification of the second embodiment of the present invention. In the example shown in the figure, the second base 124 does not include the fourth flange, and the film 130 is joined to the third flange 124A on the storage space SP side of the second base 124. In this case, the same point as the example in FIG. 7 is that in the section where the film 130 is inserted, the first engaging portions 121A, 121B and the second engaging portions 122A, 122B are not engaged, or the first engaging portion The engagement of 121A and 121B with the second engagement portions 122A and 122B weakens the engagement strength to the extent that the intermediary film 130 is equivalent to that of the intermediary film 130, so the bag 100 with the zipper can also be opened. In addition, in the example of FIG. 9, since the direction in which the film 130 extends is the same as the direction in which the content stored in the storage space SP is taken out, there is an advantage that the content does not stay near the bonding position of the film 130 and is easy to use. In the example shown in the figure, the film 130 extends on the side of the opening 101 to the same position as the first flange 123A of the first base 123. However, as in the example described above with reference to FIG. 8, the film 130 can also be arranged relative to The second base portion 124 extends to the extension portion 131 on the side of the opening 101 (the side opposite to the storage space SP), and adjusts the ease of opening the section where the film 130 is inserted.

Fig. 10 is a cross-sectional view of a bag with a chain strap in a third modification of the second embodiment of the present invention. In the illustrated example, which is different from the example described above with reference to FIG. 7, the second base 124 is joined to the second surface 111B of the bag body 110 at both the third flange 124A and the fourth flange 124B. In this case, as in the example described above with reference to FIG. 6, if the first surface 111A and the second surface 111B are grasped on the side of the opening 101, the first engaging portions 121A, 121B and the second engaging portion 122A can be used. , 122B pulls the direction of applying force, as long as the engagement strength between the first engagement portion 121A, 121B and the second engagement portion 122A, 122B is set to the degree that it is not easy to open the seal with a simple action, specifically: 26 N/50 mm or more, preferably 30 N/50 mm or more, more preferably 40 N/50 mm or more, so that it is difficult to open the bag 100 with a chain strap outside of the area where the film 130 is inserted. In the area where the film 130 is inserted, the bag 100 with the zipper can be opened.

In addition, although the above description is directed to the example in which the film 130 is joined to the bag body 110 and the example in which the film 130 is joined to the zipper tape 120, the film 130 may also be joined to both the bag body 110 and the zipper tape 120.
