  However, a latching member having a protrusion on the upper edge is simply attached to a band-shaped water-permeable filterable sheet at a predetermined interval to form a drip bag manufacturing sheet, which is applied to a bag making and filling machine, Even if an attempt is made to manufacture a drip bag in which the protruding portion of the upper edge protrudes from the upper end edge of the bag body, the intended drip bag cannot be obtained. That is, in a bag making and filling machine, generally a belt-shaped water-permeable filterable sheet is folded in two in the longitudinal direction and the edges are welded together (vertically sealed) to form a cylindrical shape, which is sequentially welded at predetermined intervals in the width direction. The contents are filled while fusing (horizontal sealing). In the drip bag manufacturing sheet to be applied to such a bag making and filling machine, even if the upper edge portion of the hooking member is arranged in the width direction of the band-shaped water-permeable filterable sheet, the hooking member The protruding portion of the upper edge portion cannot protrude from the upper end edge of the bag body. Further, the protruding portion of the upper edge portion of the latching member protrudes from the longitudinal edge portion of the band-shaped water-permeable filterable sheet.

If the latch member is disposed on the belt-like water-permeable filterable sheet as described above, the adhesive strength of the vertical seal is lowered at the protruding portion.

  On the other hand, the present invention provides a drip bag that can be easily opened even when a drip bag is manufactured using a bag making and filling machine, in which the protruding portion of the upper edge of the latching member protrudes from the upper edge of the bag body. It is an object of the present invention to provide a drip bag manufacturing sheet that can be obtained, and to provide a drip bag manufactured using the sheet.

In order to achieve the above-mentioned object, the present invention provides a latch formed of a pair of thin plate materials that latch the bag body on a cup on the opposing outer surface of the bag body formed of a water-permeable filterable sheet. A drip bag manufacturing sheet for manufacturing a drip bag provided with a member,
The band-shaped water-permeable filterable sheet has an easy-cleavage line extending in the longitudinal direction through the central portion in the width direction of the sheet, and a pair of hooking members attached at predetermined intervals in the longitudinal direction of the sheet. ,
Each of the latching members constituting the pair of latching members is a portion located on the upper edge of the latching member in the drip bag manufactured from the drip bag manufacturing sheet (hereinafter referred to as the upper edge of the latching member). , Having a latching piece formed to be able to be caused from a water-permeable filterable sheet
The upper edge part of a pair of latching members opposes so that an easy-cleavage line may be pinched | interposed, and it affixes on a water-permeable filter sheet, and provides the sheet | seat for drip bag manufacture which has the protrusion part which crosses an easy-cleavage line alternately.

  Further, the present invention provides a drip bag manufactured from the drip bag manufacturing sheet, a bag body formed from a water-permeable filterable sheet, and a pair of latches attached to the opposing outer surfaces of the bag body A drip bag having a member, wherein the upper edge of the bag body is a fold of the water-permeable filter sheet, an easy-cleavage line is formed on the upper edge, and the pair of hooking members are respectively attached to the water-filterable sheet. Provided is a drip bag having a stuck upper edge, a hooking piece formed so as to be able to be caused from a water-permeable filterable sheet, and protrusions protruding alternately from the upper edge of the bag body.

  According to the drip bag manufacturing sheet of the present invention, the water-permeable filterable sheet has an easy-cleavage line extending in the longitudinal direction through the center in the width direction, and a pair of latches so as to sandwich the easy-cleavage line. Since the upper edge of the member is opposed and the upper edge alternately has protrusions that exceed the easy-cleavage line, when the belt-shaped water-permeable filter sheet is folded in two at the easy-cleavage line, The protrusion of the upper edge of the latch member protrudes. Therefore, when this drip bag manufacturing sheet is subjected to a bag making and filling machine, folded in half at an easy-cleavage line and vertically sealed, and then a drip bag is manufactured by repeating filling of contents and horizontal sealing, the resulting drip bag The easy-opening is such that the easy-cleavage line is the upper edge of the bag body, and the protruding portion of the upper edge of the latching member protrudes therefrom. Therefore, according to the present invention, it is possible to manufacture a drip bag that is easy to open with high productivity using a bag making and filling machine.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same code | symbol represents the same or equivalent component.

  FIG. 1 is a plan view of a drip bag manufacturing sheet 200A according to an embodiment of the present invention. As shown in FIGS. 4A, 4B, and 4C, the drip bag manufacturing sheet 200A is formed of a thin plate-like material on the outer surfaces of the bag body 2 that are formed from the water-permeable filter sheet 1 and facing each other. The drip bag 100A, which includes the pair of hooking members 10A and hooks the bag body 2 to the cup 300 with the hooking members 10A, is preferably used when industrially manufactured with a bag making and filling machine.

  Here, as the water-permeable filterable sheet 1, various materials that can be brewed with coffee when a predetermined amount of coffee powder is filled and poured are used. In general, as the sheet for leaching, for example, synthetic fibers such as polyester, nylon, polyethylene, polypropylene, vinylon, semi-synthetic fibers such as rayon, woven fabrics or nonwoven fabrics composed of natural fibers such as mulberry, Mitsumata alone or in combination, Papers such as mixed paper made of Manila hemp, wood pulp, polypropylene fiber, and tea bag base paper are known, and these can also be used in the present invention, but from the point of disposal after use of the drip bag The water-filterable sheet material preferably contains biodegradable fibers. Examples of the biodegradable fiber include polylactic acid, polybutylene succinate, and polyethylene succinate. Moreover, in order to be able to impart an appropriate steaming effect to the coffee powder at the time of drip, when manufacturing a water-permeable filterable sheet from these fiber materials, it is in direct contact with the coffee powder by adjusting the porosity of the fiber layer. The layer that is in direct contact with the coffee powder is increased in the density of the multi-layered structure in which the layer to be in contact is “sparse” and the layer that is not in direct contact is “dense”. In the layer not in direct contact with the powder, it is preferable to reduce the content of hydrophobic fibers (Japanese Patent No. 3694486).

  On the other hand, the thin plate material forming the latch member 10A is formed by punching a paperboard, a plastic sheet or the like. The hook member 10A is also preferably made of a biodegradable material such as polylactic acid, polybutylene succinate, polyethylene succinate, etc., from the point of disposal after using the drip bag.

  In the drip bag manufacturing sheet 200A of the present embodiment, an easy-cleavage line 3 extending in the longitudinal direction is formed in the water-permeable filter sheet 1 so as to pass through the central portion so as to bisect its width direction. Examples of the easy-cleavage line 3 include a perforated part, a weak part formed in a line shape on the water-permeable filter sheet 1 by ultrasonic waves, heat, or the like.

  A pair of latching members 10 </ b> A (10 </ b> A <b> 1, 10 </ b> A <b> 2) are attached at predetermined intervals in the longitudinal direction of the water-permeable filter sheet 1. In FIG. 1, a portion filled with dots is a region where the retaining member 10 </ b> A and the water-permeable filter sheet 1 are adhered (hereinafter the same).

  Each hanging member 10A has a drip bag 100A formed from the drip bag manufacturing sheet 200A and causes the hanging piece 11 to be hung on the upper edge of the cup 300 from the water-permeable filter sheet 1. ing. More specifically, each latching member 10A has a central sticking part 12 stuck to the water-permeable filterable sheet 1, an arm part 13 and a latching piece formed so as to be able to be caused from the water-permeable filterable sheet. 11, one end of the arm portion 13 is continuous with the central sticking portion 12, the continuous portion is surrounded by a U-shape with the central sticking portion 12, and the other end is continuous with the latching piece 11. doing. Further, the upper edge portion 14 (that is, the portion located at the upper edge portion of the hooking member in the drip bag 100A formed from the drip bag manufacturing sheet 200A) passes oppositely so as to sandwich the easy-cleavage line 3 therebetween. It is stuck on the water filterable sheet 1. Extending portions 16 extending in a direction away from the easy-cleavage line 3 are extended at both ends of the upper edge portion 14.

  Further, the upper edge portions 14 of the pair of hooking members 10A1 and 10A2 are formed with adjacent protrusions 15 that exceed the easy-cleavage line 3 so as to alternately exceed the easy-cleavage line 3. Therefore, the pair of latching members 10A1 and 10A can be simultaneously formed by punching from a single sheet-like material, and the amount of scraping between the individual latching members can be reduced. Moreover, although the protrusion part 15 is not sticking with the water-permeable filterable sheet 1, the upper edge part 14 is sticking with the water-permeable filterable sheet 1. FIG. Therefore, as shown in FIG. 2, when the drip bag manufacturing sheet 200 </ b> A is folded in two along the easy-cleavage line 3, the easy-cleavage line 3 becomes an edge, and the protrusions 15 of the pair of latching members 10 </ b> A alternately overlap. It will protrude without.

  Therefore, when the drip bag 100A is manufactured from the drip bag manufacturing sheet 200A using the bag making and filling machine, first, as shown in FIG. 2, the drip bag manufacturing sheet 200A is folded in half, as shown in FIG. The longitudinal edges 4 are welded to form a cylinder. Then, the water-permeable filterable sheet 1 is welded and cut in the width direction between the hook members 10A arranged in the longitudinal direction (positions indicated by broken lines), and coffee powder is formed on the bag formed thereby. Etc. are alternately repeated to obtain the drip bag 100A.

  As shown in FIG. 4A, the drip bag 100A thus obtained has an upper end edge of the bag body 2 as a fold mountain of the water-permeable filter sheet 1, and has an easy-cleavage line 3 at the upper end edge. The pair of latching members 10 </ b> A attached to the opposing outer surfaces of the bag body 2 have protruding portions 15 that protrude alternately on the upper edge portion 14. Therefore, in the drip bag 100A, as shown by an arrow in FIG. 4B, the easy-cleavage lines 3 are easily opened by pulling the protrusions 15 away from each other. Therefore, as shown in FIG. 4C, the hooking piece 11 formed on the hooking member 10 </ b> A is raised and hung on the upper edge of the cup 300 to hook the bag body 2 to the cup 300, thereby pouring water into the opening. And can be easily used as a drip bag.

  The drip bag manufacturing sheet of the present invention can take various forms. For example, FIG. 5 shows a drip bag manufacturing sheet 200B in which the upper edge portions 14 of the pair of hooking members 10A1 and 10A2 are brought into contact with each other over the entire width of the hooking member 10A. It is. Thereby, the punching waste at the time of punching of the latching member 10A can be further reduced.

  In the drip bag manufacturing sheet of the present invention, there is no particular limitation on the configuration itself of the retaining piece 11 and the like. Therefore, for example, like the drip bag manufacturing sheet 200C shown in FIG. 6, the extending portion 16 is omitted from the hooking member of the drip bag manufacturing sheet 100A described above, and the center sticking portion 12 and the upper edge portion 14 are omitted. It is also possible to provide a connecting portion 17 that connects the two and the connecting piece 17, and the pair of arm portions 13 along both sides of the connecting portion 17 may cause the latching piece 11 and the center attaching portion 12 to be continuous. It is preferable that the connecting part 17 is adhered to the water-filterable sheet 1 in whole or in part. According to the latching member 10C, since the extending portion 16 is omitted as compared with the latching member 10A shown in FIG. 1, the thin plate material constituting the latching member can be saved. Moreover, since each part which comprises 10 C of latching members is continuing, the position shift at the time of sticking 10 C of latching members on a water-filterable sheet can be reduced.

  FIG. 7A is a plan view of a drip bag 100C manufactured from the drip bag manufacturing sheet 200C, and FIG. 7B is a perspective view of a state in which the drip bag 100C is hooked on the cup 300. This drip bag 100C also has an easy-cleavage line 3 at the upper edge of the bag body 2, and a pair of hooking members 10C attached to the opposing outer surface of the bag body 2 are connected to the upper edge portion 14 at the bag body. 2, the easy-cleavage line 3 can be easily opened and hooked on the cup 300 by separating the protrusion 15.
