TECHNICAL FIELD OF THE INVENTION

[0002]

2. Description of the Related Art Conventionally, it has been frequently used to attach a header portion to an opening of a synthetic resin net bag and enclose the contents in the bag body. In this case, for example, a sheet or synthetic resin sheet-shaped header portion is folded in two, sandwiched in the opening portion of the bag body, and the opening portion is closed with a stapler or the like. In addition, as shown in Japanese Utility Model Publication No. 1-1243, the header is heat-sealed to the opening of the net bag with a plastic piece sandwiched on one side of the bag, and the plastic piece is thermally welded to the other side of the bag with both sides sandwiched. There is a bag to do. Thus, the bag is closed by bonding the header portion and the plastic piece on the other surface of the bag.

[0003]

First of all, conventionally, the header portion is folded in two, and the opening portion of the bag body is sandwiched and stopped with a stapler or the like, but the stapler needle is made of metal or the like. Therefore, the bag must be closed with care, and the bag must be taken out of the bag for safety. For this reason, a synthetic resin header portion is heat-sealed in advance on both sides of the opening of the bag body opening of the synthetic resin net bag, and an adhesive tape is disposed in advance on one side of the header portion behind, and the header portions are joined together. In some cases, the bag is closed by bonding. However, in this case, the thermal welding of the header portion and the net bag has an extremely small contact area with each other, so that reliable thermal welding cannot be performed and the header portion peels off.

In addition, a long header portion is heat-welded only to one side of the bag body of the other net bag, the header portion is bent, and the tip of the header portion is adhered to the outer surface of the net bag with an adhesive tape or the like. In some cases, the bag is closed by performing the above procedure.However, as described above, the thermal welding of the header to the net bag cannot be said to be reliable, and the adhesive tape at the tip of the header and the net bag are not adhered to each other. The contact portion with the bag was extremely small and easily peeled off. Therefore, in order to eliminate these disadvantages, as shown in Japanese Utility Model Publication No. 1-1243, a header portion is heat-welded to the opening of the net bag with a plastic piece interposed therebetween, and a plastic piece is attached to the other surface of the bag body. There is a bag that is heat welded with both sides sandwiched between them, but since the header part on one side of the bag is adhered to the plastic piece on the other side of the bag, the header part and the plastic piece on the other side of the bag body Although the adhesive strength between the two increases, even if the header is heat-sealed to the opening of the net bag with the plastic piece interposed, the net bag interposed between the two has extremely small contact areas on both sides, ensuring reliable contact. Heat welding could not be performed.

Therefore, even when the net bag is sandwiched between the header portion and the plastic piece on one side of the bag and thermally welded, both of them have a small contact area with the net bag and are easily peeled off. Even when the net was heat-welded with both sides sandwiched by plastic pieces, the contact area between each plastic piece and the net was small and easily peeled off. On the other hand, Japanese Unexamined Patent Application Publication No. 11-310246
As shown in the figure, there is a case where the welding surface is increased by increasing the contact surface by flattening the net ground part of the welded part, but for example, when making the net ground part flat, the flatter the net While the portion is widened, the net portion is thin and the strength of the net bag itself is low.

Further, when the degree of flattening is reduced, the contact surface becomes almost the same as that of the conventional thermocompression bonding, and for example, the contact portion between the header portion and the net ground portion remains small. Especially when the header part and the net base part are thermocompression-bonded, not only the header part is interposed and heat conduction is not good, but also there is a possibility that a clean bag cannot be made due to the difference in melting temperature between the header part and the net. There is also. As described above, the invention of a header or a bag using the header, which can easily close the bag when the opening is closed by the header although the contents are easily enclosed in the bag and the net is a bag. Is what is desired.

[0007]

According to the first aspect of the present invention, there is provided a header for closing a mesh-shaped bag opening, and the header is symmetrically adhered to the inside of the header located on both sides of the bag. This can be achieved by a header having an adhesive member which is formed by applying a member and allowing the header located on both sides of the bag located between the headers to be adhered by the adhesive. Alternatively, a header portion for closing the mesh-shaped bag opening portion as in the invention according to claim 2, wherein the bag portion is sandwiched between the header portions to close the opening portion of the bag body, and the bag portion is closed. An adhesive member is applied to at least a part of the inside of the header portion located on both sides, and the adhesive member is an adhesive member that reaches the header portion on the other surface along the gap or mesh of the mesh of the sandwiched bag body. The same can be achieved by a header portion having an adhesive member that enables the bag member located between the header portions and the header portions on both sides of the bag member to be adhered by the adhesive member.

[0008] Alternatively, the bonding effect can be exerted by mixing by sandwiching each of the header portions even with a header portion having an adhesive member in which the adhesive member is a two-component adhesive member as in the invention according to claim 3. In addition, the present invention can be solved by a header having an adhesive member in which the adhesive member is a hot melt. Alternatively, as in the invention according to claim 5, the adhesive member coating of the header portion is provided with an elastic body having a gap in the header portion, and the header portion having the adhesive member having the adhesive member in the gap, A certain amount of the adhesive member can be appropriately disposed at a necessary place. Specifically, the bag object using the header portion as described above, which is the bag itself using such a header portion, can also achieve this object.

[0009] Therefore, even if the header portion is integrally disposed on the bag itself in advance, or the bag and the header portion are separately formed and used for the bag, this problem is similarly solved. Can be achieved. In this case, the same applies to a bag having a header portion in which the mesh-shaped bag is a net bag as in the invention according to claim 7. Alternatively, as in the invention according to the eighth aspect, the mesh-shaped bag may be a bag having a header portion, which is a bag having a stretchable mesh in which monofilament-shaped filaments are crossed and integrated. Alternatively, as in the invention according to claim 9, the mesh-like bag may be a bag having a header portion which is a bag made of non-woven mesh or woven mesh. Therefore, whether it is made of a so-called synthetic resin or not may be made of a non-woven fabric or a woven fabric, and may be a bag having at least a non-woven mesh shape or a woven mesh shape mesh. is there.

[0010]

FIG. 1 is a view showing an embodiment of a bag according to the present invention. Reference numeral 1 denotes a bag, and a net bag is shown in the figure. This net bag is a mesh-shaped bag body 1, for example, a bag body having an elastic mesh 1b which crosses monofilament-shaped filaments and is integrated, or a bag body formed of a nonwoven fabric shape or a woven fabric shape. It may have a configuration. Non-woven or woven mesh with mesh structure 1
b. Further, for example, the bag 1 is not limited to the synthetic resin bag 1 but may be a cloth or paper bag, and the material is not limited.

It is sufficient that at least the mesh-shaped bag 1 is used. Here, the mesh is not limited to the bag 1 which is coarsely knitted with a constant or irregular interval, for example, as long as the bag-like shape of the mesh 1b can be seen and viewed so as to allow ventilation and water flow. The shape is not limited to the one having the eye 1b regularly, but may be any one having the eye-shaped portion 1b having an arbitrary shape and size. For example, a fixed or indeterminate object which crosses a member of an arbitrary shape such as a striated object, a rod-shaped object, a three-dimensional object, a planar object, or a twisted or bundled member of the plurality, and is a mesh 1b of the external appearance. Any shape may be used as long as it has a substantially hole-like shape and allows ventilation and water flow. Therefore, the intersection is not limited to the double intersection, but may be a multiple intersection, and may be not only a woven one but also an overlapping one or an arbitrary one. The state of intersection in this case is not limited to a fixed interval, but may be an intersection at any different interval.

Also, this intersection is not limited to an overlapped shape,
Integrally molded ones, for example, those having holes like a mesh 1b with a large number of holes formed in a sheet-like material are included, and, for example, the filaments are crossed and fused together,
They may be integrated to the extent that the boundaries between the striated objects are lost. Therefore, in the present application, the mesh 1b, that is, the bag 1 having a hole-like appearance is all included in the mesh bag 1. The opening 1a of the bag body 1 covers the opening 1a of the bag body 1 in a configuration in which the header portion 2 folded in half is put over the opening 1a. With this configuration, the opening 1 of the bag 1
a is to be closed. The header 2 is bonded at two places in the width direction of the bag 1. That is, the header portion 2 has a two-fold structure, and the adhesive members 3 are applied to the inside of each of the bent pieces 2a, 2a at two places. 3 is attached to the bag 1. With such a configuration, the adhesive members 3 of the respective bent pieces 2a, 2a are filled between the meshes 1b of the mesh-shaped bag 1b, and the adhesive members 3 penetrate without gaps, thereby maintaining the adhesive strength. And

FIG. 2 shows a bag according to the present invention in which the bag 1 is formed of a sheet-like material, and has a plurality of meshes 1b, which are formed in a hole-like shape and have holes as seen from the outside. It is a figure showing the state where header part 2 was arranged in an example of reticulated bag 1. Even in the mesh-shaped bag 1 shown in this figure, the adhesive member 3 can enter the mesh 1b portion of the mesh to maintain the adhesive strength. In addition, the liquid adhesive member 3, for example, permeates both sides of such a planar net portion, thereby enabling the entire adhesive. FIG. 3 is a cross-sectional view taken along line AA of FIG. 1, and the header 2 is folded in two at the opening 1 a of the bag 1.
Is covered, and the bag 1 is sandwiched between the bent pieces 2a, 2a of the header portion 2 to close the bag 1. In this case, the adhesive members 3 provided inside the bent pieces 2a, 2a are integrated via the bag body 1 and enter the gap of the mesh body 1b of the bag body to bond only the conventional net, that is, the net mesh portion. Instead, it is also adhered to the eye 1b and wrapped around the net portion to be integrally adhered.

Therefore, regardless of the thickness and width of the mesh portion or the mesh interval, the mesh portions are integrally bonded by the adhesive members 3 provided inside the bent pieces 2a. FIG. 4 is a diagram showing a state where the header section 2 is separated,
Each of the folded pieces 2a, 2a is formed by a two-fold configuration, and the adhesive member 3 is applied to the inside of each of the folded pieces 2a at two places. Therefore, the header 2 is placed over the opening 1a of the bag body 1 and the folded pieces 2a are sandwiched between the headers 2 so that the respective bonding members 3 are connected to the mesh 1b.
And the adhesive members 3 in the other surface direction are brought into contact with each other, and the respective adhesive members 3 are integrally bonded to each other, so that the bag body 1 can be closed. In this case, the adhesive member 3 is not limited to a natural adhesive but may be a synthetic adhesive, and may be a thermosetting adhesive or a pressure-sensitive adhesive as well as a thermoplastic. Alternatively, the present invention is not limited to the adhesive, and an adhesive having an adhesive property is also included in the adhesive member 3 in the present invention.

Therefore, in the present invention, the adhesive member 3 corresponds to any member that can bond or adhere at least one member to another member. For example, an adhesive such as a hot melt or a polyurethane resin adhesive may be used, and an adhesive used for an adhesive tape or the like may be used. In addition, for example, each folded piece 2a,
Even if the adhesive member 3 is applied to the inside of 2a and the two are adhered together, for example, the two-component adhesive member 3 may be used instead.
May be applied to each. That is, in the case of the two-component adhesive member 3, the main agent is applied to the inside of one folded piece 2a, and the primary agent such as a curing agent or an accelerator is applied to the back side of the other folded piece 2a. They may be bonded by causing them to adhere. In addition, for example, one obtained by applying one of the two liquids as the main agent to each bent piece 2a, such as an acrylic resin two-liquid main agent type, may be used. In the case of a two-part type, one part is applied on one side and the other part is applied on the other side, and the two parts are brought into contact with each other for adhesion.

The adhesive member 3 not only fills the gaps of the mesh 1b of the bag 1 with a so-called solid shape but also the mesh 1 of the bag 1 such as a liquid.
It may penetrate into the gap of b and adhere at many places. For example, in the case of using the bag 1 having the elastic mesh 1b which crosses and integrates the monofilament filaments, the adhesive member 3 made of the liquid penetrates along the monofilament filaments by the capillary phenomenon. Then, the monofilament-like filaments and the header portion 2 are bonded in a wide range. Therefore, both the bent pieces 2a, 2a of the header portion 2 located on both sides of the bag body 1 and the bag body 1 are bonded in a wide range and at many parts. These are all determined by the content and type of the adhesive member 3,
The portion of the mesh 1b of the bag 1 sandwiched between the headers 2 is bonded at a number of places to enhance the bonding strength, and when the contents are put in the bag 1, the bag 1 is removed. The opening 1b can be closed very easily by combining the two folded pieces 2a, 2a of the sandwiched header 2.

If, for example, the adhesive member 3 is liquid and it is difficult to apply a fixed amount of the adhesive member 3 to the header portion 2, for example, a sponge-like material or cotton A certain amount of the adhesive member 3 can be applied by disposing a material or the like in the corresponding portion and impregnating the adhesive member 3. Since the elastic body 4 has a gap, a certain amount of the adhesive member 3 can be held in the gap, and a necessary amount of the adhesive member 3 can be held when bonding or sticking. For example, the two-component adhesive member 3 is useful because it does not harden with only one component. Further, if it has elasticity, when the header portions 2 located on both sides of the bag body 1 are pressed together, the elasticity narrows the gap, so that the internal adhesive member 3 is pushed out and the mesh of the bag body 1, for example. 1b, it is possible to protrude, thereby improving the adhesive strength.

In addition, the elastic member 4 such as the sponge-like material enters the mesh of the bag 1 by the above-described method, thereby increasing the adhesive strength. Alternatively, a tape or the like in which the adhesive member 3 is penetrated or applied, or an elastic adhesive tape or the like may be used. Any material can be used as long as the adhesive member 3 can be arranged and maintained at least in necessary places. FIG. 5 is a sectional view taken along line BB of FIG. An adhesive member 3 is applied to the inside of each of the folded pieces 2a, 2a of the header portion 2 formed by the two-fold configuration when the folded pieces are put together. As described above, the two-fold configuration of the header portion 2 is explicitly described. However, the present invention is not limited to this. For example, two separate header portions 2 and 2 located on both surfaces of the bag body 1 are used, and the adhesive member 3 is applied to each. And the bag 1 is adhered to the opening 1a.
a may be closed. Alternatively, an adhesive member 3 may be applied to each of a plurality or a large number of individually divided header portions 2, and the opening portions 1 a may be closed by appropriately bonding the adhesive members 3 from both sides of the bag body 1.

At least the inside of the header 2 located on both sides of the bag 1 is coated with the adhesive member 3 symmetrically, and the bag 1 located between the headers 2 and the headers on both sides of the bag 1 are provided. 2 can be adhered by the adhesive member 3, and even if one header portion 2 is folded in two, or two individual header portions 2 are coated with the adhesive member 3 at symmetrical positions. When one header section 2 itself is formed by combining a plurality of individual header sections, the header section 2 may be formed by combining the respective header sections. Alternatively, two sheet-shaped header portions 2 may be fused 2b at one side thereof, and the header portion 2 having two pieces connected at one side thereof may be used. In this figure, the header 2 is shown as being separated from the bag 1 as a separate member. However, the present invention is not limited to this. For example, the header 2 according to the present invention is previously adhered or fused to one surface of the bag 1. In addition to this bonding or fusion, an adhesive member 3 is applied to the inside of the header 2, and the bag 1 is sandwiched by the adhesive 3 and the opening 1 a of the bag 1 is closed by the header 2. It may be.

FIG. 6 shows an example in which two sheet-like header portions 2 are fused 2b at one side thereof, and the opening portion of the bag body 1 is formed by using the header portion 2 having two pieces connected at one side thereof. 1
6 is an example showing a state in which the header portion 2 is sandwiched in a state in which a is bent. By closing the bag in this manner, the bag 1 can be closed, and when the bag 1 is opened again and the contents are taken out, the main body of the bag 1 and the bent portion are widened to form a substantially linear shape. 2 can be peeled off. Also in this case, if the adhesive member 3 of the header portion 2 has a solid shape such as hot melt, the adhesive member 3 is filled between the meshes 1b of the bag body 1 and penetrates without gaps to maintain the adhesive strength. To make things possible. Therefore, even if the folded mesh-like bag 1 sandwiched between the headers 2 has a certain width, the bag 1 can be closed and the adhesive strength can be maintained. I do. On the other hand, even if the bag body 1 is once closed in this way, the closure of the bag body 1 can be reopened, and the adhesive member 3 is not used near the opening 1a. The opening 1a is expanded to facilitate taking out the contents.

It is to be noted that, even when a fixed amount of liquid adhesive member 3 is used instead of the solid adhesive member 3, the adhesive member 3 covers the entire mesh portion of the mesh between the corresponding headers 2. Penetration allows bonding over a wide range. Alternatively, for example, by disposing the elastic body 4 having a gap and disposing the adhesive member 3 in the gap, sufficient adhesion can be achieved. FIG. 7 is a diagram showing a state in which the adhesive member 3 is applied to the header portion 2, and the adhesive member 3 is applied symmetrically to two portions with the folded portion interposed therebetween. A release paper 5 is placed on the surface of the adhesive member 3 so that the adhesive member 3 cannot be exposed at normal times. Therefore, when the contents are put in the bag 1 and the opening 1a of the bag 1 is closed by the header portion 2, the release paper 5
Can be used after peeling off. FIG. 8 is a view showing another embodiment, and FIG. 8 (1) shows that the header 2 is folded in two, and the adhesive member 3 is applied to the inside of each of the bent pieces 2a, 2a and folded in two. FIG. 4 is a diagram showing a state where a release paper 5 is sandwiched between header portions 2. With this configuration, the adhesive member 3 is exposed when the release paper 5 is peeled off during use.

FIG. 8B is a sectional view taken along line CC of FIG. 8A. FIG. 8 (3) is a view showing one embodiment showing a state in which the folded release paper 5 is sandwiched. FIG. 8 (4) shows an example in which the two sheet-like header portions 2 and 2 shown in FIG. 6 are fused 2b at one side thereof, and the two sheet-like header portions 2 and 2 are connected at one side thereof. FIG. 6 is a view showing an embodiment showing a state in which a release paper 5 is sandwiched between the sheets. FIG. 9 is a view showing another state of application of the adhesive member 3 to be applied to the header portion 2. FIGS. 1 to 8 show the basic form in which each of the bent parts 2a, 2a or the header part 2 of the header part 2 is coated with the adhesive member 3 at two places symmetrically, but the present invention is not limited to this. For example, as shown in FIG. 9A, three portions may be provided in parallel, or as shown in FIG. 9B, three portions may be provided with steps. Alternatively, although not shown in the drawing, for example, each of the bent pieces 2a, 2a of the header portion 2 may be provided with one adhesive member 3 application site or three or more sites.

These may be appropriately determined according to the size of the bag 1, the size of the header 2, the material thereof, the contents to be put in the bag, and the like. Also, as shown in these figures, each of the broken pieces 2a, 2
The bonding members 3 are not limited to the bonding members 3 provided symmetrically, and may be, for example, the bonding members 3 applied asymmetrically. In this case, for example, in the case of the two-component adhesive member 3, mixing of the two components is necessary. However, if one kind of adhesive member 3 is sufficient, such as hot melt, for example, the coating of the adhesive member 3 is performed. By increasing the amount of attachment, the adhesive member 3 can penetrate through the gap between the meshes 1b of the mesh-shaped bag to the inner surface of the header 2 on the other side, and the adhesive member 3 is applied only on one side. Even if it does, it can be bonded and the bonding strength can be maintained. Further, even in the case of the two-component adhesive member 3, for example, in the case of the two-component main agent type adhesive member 3, the dispenser or the like capable of applying the two components in an overlapping manner is used to separate the two components from each other. It is not necessary to coat the header portion, and it is possible to bond by overlapping the header portion by applying each main agent of the two-component main agent type only on one surface.

Therefore, the adhesive members 3 are not necessarily symmetrically attached to both sides of the surface of the header 2 where the bag 1 is sandwiched or adhered.
Need not be applied as long as the adhesive member 3 is applied to at least a part of the inside of the header 2. Therefore, even if the adhesive member 3 is asymmetrically applied to each of the bent pieces 2a of the header portion 2,
The adhesive member 3 may be applied only to a. FIG. 10 is a diagram showing an embodiment in which the adhesive member 3 is applied only to one bent piece 2a of the header portion 2. FIG. FIG.
FIG. 10A is a cross-sectional view illustrating a state in which the header portion 2 folded in two in the direction of the opening 1a of the bag body 1 is sandwiched.
FIG. 2B is a cross-sectional view in which the folded header portion 2 is sandwiched and put in a palm-split state.

Accordingly, the adhesive member 3 of one of the folded pieces 2a passes through the gap of the mesh 1b of the mesh-like bag 1 and the other of the folded pieces 2a.
, And it becomes possible to bond the bag body 1 with the bag body 1 sandwiched therebetween. FIG. 10 (3) is a view showing a state where the adhesive member 3 is applied at two places to one bent piece 2a of the header portion 2. FIG. FIG. 10D is a diagram illustrating a state in which the adhesive member 3 is asymmetrically applied to each of the bent pieces 2 a of the header portion 2. Therefore, even when the adhesive member 3 is applied in this manner, the opening 1a of the mesh-shaped bag 1 can be securely and firmly closed by the header 2.

[0026]

1. By using the header portion according to the present invention in a mesh-like bag, the adhesive member of the header portion enters the gap of the mesh of the mesh-like bag, and a conventional net, that is, a mesh net. In addition to the bonding of only the part, the bonding is also performed on the eye part by wrapping the net part and integrally bonding, so that the header part and the net-shaped bag body can be securely bonded. It has one effect. Therefore, it is possible to prevent the header portion from being accidentally detached from the bag. 2. Also, even when, for example, a liquid adhesive member is used, the liquid adhesive member penetrates the surface of the mesh portion of the bag instead of bonding only the mesh portion of the mesh of the bag contacting the header portion. This has the second effect that the entire net portion sandwiched between the header portions can be adhered and the header portion and the mesh-like bag can be securely bonded. Third, by disposing an elastic body having a gap in the header portion, there is a third effect that a necessary amount of the adhesive member can be disposed at a required position. 4. Further, it can be used irrespective of the thickness and width of the mesh portion of the mesh portion of the mesh-like bag or the mesh interval, and has a fourth effect that an extremely versatile header portion can be provided.

5. The fifth advantage is that the header portion can be manufactured integrally with the bag, and the header portion alone can be used for a mesh-shaped bag made of any other member by manufacturing the header alone. 6. The bag body can be closed by bonding the header portion with the adhesive member at the opening of the bag body, and the bag body can be closed very simply and with good workability because the bonding member only needs to be bonded. This has the sixth effect. 7. Adhesive members may be appropriately arranged on the header portion, and the seventh effect is that it can be manufactured extremely easily and at low cost.
