Description

  The present invention relates to, for example, a package for packaging materials to be filled such as liquids, pastes, powders, granules, tablets and the like in food, medicine, cosmetics and the like, and more specifically, the inside of the filling portion The present invention relates to a method and an apparatus for manufacturing a package that can be filled in a filled state.

  Up to now, various packages have been proposed as packages which can package the above-mentioned material to be filled in a necessary amount and take out the material as required, as described in Patent Document 1 The disclosed package is also one such package. In the package of Patent Document 1, the filling portion which allows the filling of the material to be filled is formed between a fairly rigid flat sheet and a flexible sheet laminated to one side of the flat sheet, and broken. An openable opening portion is formed in a folded portion of the flat sheet, and a sealant made of a sealant is coated on both sides or one side of the flat sheet.

However, when the flat sheet and the flexible sheet described above are bonded to each other, for example, fluctuation or slip of the transfer force generated when transferring the sheets in the feeding direction by the sheet feeding means, or the longitudinal direction of the sheet itself Due to the expansion and contraction that occurs in the sheet, the sheets tend to shift.
For this reason, when the material to be filled is filled into the filling portion formed between the sheets, the material to be filled is likely to leak from the portion where the sheets are shifted, or to leave air in the filling portion. It is difficult to fill the filling material in such a way that the inside of the filling part is filled. Moreover, it is difficult not only that the material filled in the package is degraded (oxidized) by air but also it is difficult to maintain the quality of the material for a long time.

  The unsealing portion is, for example, a fracture opening structure for breaking and opening the sealing material bonded to cover the cuts formed in the sheet member, or between two cuts formed in the sheet member and the film member It can be configured with a peeling and opening structure or the like in which the peelable portions of the corresponding members are peeled and opened. The material to be filled can be, for example, liquid, paste, powder, granules, tablets, and the like.

  The packaging material feeding means can be constituted by, for example, a feeding roll, a feeding belt or the like. The vertical sealing means can be constituted, for example, by a vertical sealing device provided with a rotary seal roll. The lateral sealing means can be constituted by, for example, a lateral sealing device provided with a rotary seal roll. The filling means may comprise, for example, a filling device or the like connected to the filling material supply source. The dividing means can be configured by, for example, a dividing device provided with a rotary type rotary blade.

  The positioning mark is a concept including, for example, a mark of a desired shape printed on a packaging material, a pattern, a figure, or a hole, a notch, or the like formed in the packaging material. The misalignment of the positioning mark is a concept including, for example, the misalignment of marks or patterns printed on the packaging materials, the misalignment of the sealing position to be heat sealed by the sealing means, the misalignment of the dividing position to be divided by the dividing means, and the like.

  The mark detection means can be configured by, for example, a mark detector, a photoelectric sensor, a CCD camera or the like. The determination means can be configured by, for example, a program stored in a CPU or a ROM, a determination device including the CPU, or the like. The deviation adjustment means can be constituted by, for example, a feed roll for longitudinally feeding the packaging materials in the feed direction, a seal roll for heat sealing the overlapping portions of the packaging materials, a control unit for controlling the rotation of the rolls, etc. .

According to this aspect of the invention, the package can be easily opened simply by folding it in a half-folded state, and it is possible to manufacture a package in which the material to be filled is filled in a state where the inside of the filling portion is filled.
Specifically, in the overlapping step, one and the other packaging materials are overlapped with each other in such a manner that the part of the one packaging material to which the sheet member is attached and the part of the other packaging material forming the filling part face each other. While aligning, the packaging material feeding means longitudinally feeds in the downward feeding direction. That is, the packaging materials are superimposed on each other so that the sheet member in one packaging material covers the filling portion in the other packaging material.

  In the vertical sealing process, while vertically feeding the packaging materials in the lower feeding direction, the overlapping portions on both sides along the feeding direction in the packaging materials are heat sealed by the vertical sealing means in the feeding direction. to paste together. In the filling step, the filling material is filled from above into the cylindrical package formed by heat-sealing the overlapping portions on both sides by the filling means.

  In the horizontal sealing step, while longitudinally feeding the cylindrical package supplied from the vertical sealing step in the feed direction, the overlapping portion in the direction crossing the feeding direction corresponding to the space between the filling portions in the cylindrical package is It heat-seals and bonds together by the transverse sealing means in the direction (specifically, the width direction orthogonal to the longitudinal direction in the packaging materials) which intersects the feed direction.

  The tubular package is vertically fed in the feed direction by the pitch at which one package is longitudinally fed by the packaging material feeding means, and the filling portion filled with the material to be filled is moved downward. When heat sealing the lower overlapping portion of the next filling portion with the lateral sealing means, the upper overlapping portion of the previous filling portion is also heat sealed to lower the lower portion of the filling portion filled with the material to be filled. And seal the upper overlapping part.

  Thus, the filling portions filled with the filling material are individually separated by the upper and lower heat sealed portions, and the filling portions filled with the predetermined amount of filling material are separated by a predetermined distance in the longitudinal direction of the cylindrical package. To form many.

  In the dividing step, while the cylindrical package supplied from the horizontal sealing step is longitudinally fed in the feed direction, the heat-sealed portions of the cylindrical package corresponding to the spaces between the filling portions cross the feed direction by the dividing means. In order to separate into individual packages filled with a predetermined amount of material to be filled.

  As a result, it is possible to easily open the bag only by folding it in a half-folded state, and it is possible to continuously produce many packages filled with the material to be filled so that the inside of the filling portion is filled. Specifically, a tear-openable or peel-openable package can be manufactured.

  Further, since the overlapping portions of the packaging materials are thermally welded while the packaging materials are longitudinally fed in the feed direction, the overlapping portions of the packaging materials can be thermally welded stably at high speed. For this reason, manufacturing efficiency can be improved by manufacturing a package using the manufacturing method and manufacturing apparatus of this invention.

  Moreover, since the overlapping portions on both sides of the packaging materials are melted and thermally welded to each other by the vertical sealing means, for example, if the deviation is about + -1% to + -5%, the melting of the overlapping portions is used Then, the packaging materials can be moved relative to each other in the feed direction.

  That is, the packaging material feeding means makes the feeding speed of one of the packaging materials which is shifted among the packaging materials slower or faster than the feeding speed of the other packaging material, or stops the feeding. By moving the materials relative to each other in the feed direction, the misalignment between the packaging materials can be easily adjusted.

  Furthermore, when heat welding of the overlapping portions corresponding to the space between the filling portions from the bottom by the horizontal sealing means while longitudinally feeding the cylindrical package in the feed direction, the filling material filled in the cylindrical package is While pushing up, heat welding is performed on the overlapping portion corresponding to the space between the filling portions in the cylindrical package.

In other words, even if air remains in the filling part, it is difficult to leave air in the filling part, for example, since it is difficult to leave air in the filling part, since it is heat sealed while pressing upward from the bottom by horizontal sealing means. The filling portion can be reliably filled in a filled state.
Thereby, it is possible to prevent the material to be filled filled in the filling portion of the package from being denatured (oxidized) by air and to maintain the quality of the material to be filled for a long time.

Furthermore, in the case of heat sealing the overlapping portions of the packaging materials, for example, the peripheral portion having a small thickness in at least one of the packaging materials is compared with the peripheral portion having a large thickness in the other packaging material. By heat welding, the heating time required for the heat welding is shorter and the amount of heat consumption can be reduced, as compared with heat welding of the thick peripheral portions of the packaging materials.
As a result, since the welding time at the time of heat-sealing packaging materials can be shortened significantly, the cost which manufacture of a package can require can be reduced.

In addition , it is possible to more accurately manufacture a package which can be easily opened by simply folding in a half-folded state.
Specifically, when heat sealing the overlapping portions on both sides of the packaging materials by the vertical sealing means, the positioning marks attached to the packaging materials are detected by the mark detecting means, and the positioning marks detected by the mark detecting means are The deviation is compared with a preset threshold by the determination means to determine whether the deviation is less than the threshold.

  The displacement caused in the feeding direction between the packaging materials is caused, for example, by fluctuation or slip of the transfer force generated when transporting the packaging materials in the feeding direction, or expansion or contraction generated in the longitudinal direction of the packaging materials themselves. However, even if misalignment occurs between the packaging materials, if the misalignment adjustment is as small as unnecessary, the determination means determines that the misalignment between the positioning marks is less than the threshold, and the misalignment adjustment between the packaging materials is unnecessary.

  When it is determined that the misalignment adjustment is not necessary, the packaging material in which the part of the one packaging material to which the sheet member is attached and the part of the other packaging material where the filling part is formed is superimposed on each other. The overlapping portions on both sides of each other are heat-sealed and attached in the feed direction by the vertical sealing means.

  When the misalignment between the packaging materials is large enough to require misalignment adjustment, the misalignment between the positioning marks provided to the packaging materials is also large, so the determination means has a misalignment between the positioning marks greater than or equal to the threshold value. It is determined that it is necessary to adjust the deviation of

  When it is determined that the misalignment adjustment is necessary, for example, based on the determination result by the determination means, the feeding speed of one of the packaging materials which is shifted by the packaging material feeding means is the feeding speed of the other packaging material. Depending on the deviation of the positioning mark determined by the determining means, such as by making the speed slower, faster, or stopping the feeding, the packaging materials are fed so that the positioning marks coincide with each other by the deviation adjusting means Do.

  Thus, for example, the misalignment of marks or patterns printed on the packaging materials, the misalignment of the sealing position to be heat sealed by the sealing means, or the misalignment of the dividing location to be divided by the dividing means, etc. As a result, the overlapping portions on both sides of the packaging materials can be heat-sealed and attached in the feed direction by the vertical sealing means.

  As a result, in the one and the other packaging materials, the part of the one packaging material to which the sheet member having the opening part is attached and the part of the other packaging material in which the filling part is formed are accurately opposed to each other. As it is possible to bond them together, it is possible to more accurately manufacture a package which can be easily opened simply by folding in a half-folded state.

  Further, as an aspect of the present invention, a large number of the sheet member and the filling portion are arranged at predetermined intervals in the longitudinal direction of the one and the other packaging materials, and the positioning marks are attached to the one packaging material While being attached to the position corresponding to the said sheet member and the said filling part formed in the said other said packaging material, many can be arrange | positioned at predetermined intervals in the longitudinal direction of this packaging material.

According to the present invention, it is possible to continuously produce a large number of packages with higher accuracy, which can be easily opened only by folding in a half-folded state.
More specifically, the positioning marks provided at the positions corresponding to the sheet members in one packaging material and the positioning marks provided at the positions corresponding to the filling portion in the other packaging material are fed and adjusted to coincide with each other.

Thus, the one and the other packaging materials can be accurately bonded together in a state in which the part of the one packaging material to which the sheet member is attached and the part of the other packaging material in which the filling part is formed face each other. it can.
As a result, it is possible to easily open the package by simply folding it in a half-folded state, and it is possible to continuously produce a large number of packages filled with the material to be filled so that the inside of the filling portion is filled.

  As an aspect of the present invention, one of the packaging materials is configured by laminating a film member disposed on the side corresponding to the filling portion in the packaging material and the sheet member disposed on the opposite side to the filling portion A foldable foldable portion formed by folding the unsealing portion in a portion where the film member and the sheet member are bonded to each other, and breaking and unsealing in the thickness direction of the members by bending the sheet member A foil-like sealing material which is formed of a break opening part and which has a thickness which can be broken by bending the sheet member, is the open part with respect to at least one of the front and back sides of the sheet member. It can be pasted together so as to cover it.

  The above-mentioned breaking and unsealing part can be constituted, for example, by a slit, a long hole, a long groove, etc. penetrating in the thickness direction of the sheet member, but it is a shape which can be broken open by cutting the sealing material. For example, it may be formed into a long hole, a long groove, or another shape without any problem.

  The sealing material can be made of, for example, a thin foil such as an aluminum foil, a copper foil, a stainless steel foil, an iron foil, or a resin film. For example, when an aluminum foil having a thickness of 5 to 35 μm is used as a sealing material, it is possible to obtain a good tear-opened package having moisture permeability, gas permeability, and tear-openability.

  In addition, other materials having good moisture permeability and gas permeability instead of aluminum foil, for example, films made of polyvinylidene chloride, composite materials complexed with other synthetic resins, aluminum vapor deposited good films etc, etc. The material may be made of a material according to the properties and physical properties of the content, and a material with low tear strength is desirable.

According to the present invention, it is possible to manufacture a package which can be easily broken and opened only by folding in a half-folded state.
Specifically, the bent portion of one of the wrapping materials in the package was formed into a bent portion by bending it in half so that the film member in one wrapping material is on the inside and the sheet member is on the outside. The rupture and unsealing part is ruptured and opened so that the fracture-side end face of the fracture and unsealing part is exposed to the outside, and the sealing material bonded so as to cover the fracture and unsealing part is ruptured and unsealed.

The sealing material is pulled in the bending direction due to the exposure of the fracture side end face at the fracture opening part, but the elongation of the sealing material becomes a limit during bending in the two-folded state, so the fracture opening is carried out Ru.
As a result, the entire package is folded in two, and the entire filling portion is deformed so as to squeeze out, and the material to be filled filled in the filling portion is taken out from the fractured and opened part to be broken. use.

  As a result, only by folding the package in two, it is possible to easily and easily break open the break opening portion to a size that allows removal of the filling material filled in the filling portion, and the break opening operation. The required amount can be taken out smoothly from the broken open part.

  Further, as an aspect of the present invention, one of the packaging materials is configured by laminating the sheet member disposed on the side corresponding to the filling portion in the packaging material and a film member disposed on the opposite side to the filling portion. And a peelable foldable portion formed in a portion where the unsealing portion is formed by bonding the film member and the sheet member to each other, and a peeling area in which the members set in the bending portion are peeled. Formed by cutting the sheet member so as to be able to penetrate in the thickness direction of the members by bending the sheet member, and the cut is formed to intersect with the direction corresponding to the bending direction of the bending portion, It arrange | positions predetermined spacing with respect to the direction corresponding to the bending direction of this bending part, and arrange | positions at least the opposing surfaces in the said peeling area in the said members between the said opposing surfaces It can be attached to the peelable by wearing layer.

The direction corresponding to the bending direction is, for example, a concept including the longitudinal direction of the package formed in a flat substantially rectangular shape, or the longitudinal direction of the sheet member and the film member.
The film member may be, for example, a single material such as biaxially oriented polyester (OPET), biaxially oriented polypropylene (OPP), polyethylene (PE), cellulose propionate (CP), or metal (aluminium, or cardboard, metal sheet, etc.) Or it can comprise by the sheet member formed with the composite material.
Specifically, it is configured of a sheet base made of the above-mentioned material and a sealing material made of synthetic resin integrally bonded to one side of the sheet base.

The sheet member is, for example, amorphous polyethylene terephthalate (A-PET), polypropylene (PP), biaxially oriented polyester (OPET), biodegradable plastic (PLA), polycarbonate (PC), polyethylene (PE), polystyrene (PS) And so on.
In addition, the material and thickness of one and the other packaging material can be changed according to the kind of filling object, the internal shape of a filling part, etc., for example.

  The adhesive layer can be made of, for example, a hot melt adhesive, a urethane adhesive, or another adhesive. In addition, in the case of adjusting the strength of peeling adhesion in the adhesive layer, for example, a method of adjusting by pressure, heating temperature, pressurization time or heating time at the time of thermocompression bonding, and pressure jig or heating jig The desired strength and weakness can be obtained by a method of adjusting the pressure surface shape, a method of adjusting the composition of the adhesive, and a method of adjusting the application pattern of the adhesive.

According to the present invention, it is possible to manufacture a package which can be easily peeled and opened only by bending in a half-folded state.
Specifically, by bending the folded portion of one of the packaging materials in the packaging body in a folded manner so that the sheet member in one packaging material is on the inside and the film member is on the outside, the inside of the peeling area between the members is The releasably bonded portion can be peeled and opened against the adhesive force of the adhesive layer.

  That is, the radius of curvature of the sheet member is larger than that of the film member at the bending portion, and the film member is compressed and contracted by bending, but the sheet member is pulled in the bending direction by the tensile force applied to the bending portion.

  As a result, the releasably bonded portions in the peeling region of the members are displaced in opposite directions, so the releasably bonded portions in the peeling region corresponding to between the notches in the members are It can be peeled and opened against the adhesive force of the adhesive layer.

As described above, when one of the packaging materials is folded in half, the peelable portions of the members can be peeled and opened, and the cuts formed in the members can be penetrated in the thickness direction. That is, the cut formed in the members is communicated with the filling portion filled with the filling material, and removal of the filling material filled in the filling portion is permitted between the opposing surfaces in the peeling region of the members. It can be open in size and shape.
As a result, the to-be-filled thing with which the filling part of the package body was filled can be smoothly taken out from the part by which peeling and opening were carried out in packaging materials.

  In addition, the cuts formed in the members do not communicate with each other until the peelably opened portions in the peeling region of the members are peeled apart, and the filling material filled in the filling portion leaks Can be prevented reliably.

  Furthermore, due to the internal pressure of the material to be filled filled in the filling portion, the releasably bonded portions in the peeling region of the members are pressed against each other, for example, by bending or bending, so that the material to be filled leaks. Can be prevented more reliably.

  According to the present invention, it is possible to provide a method and an apparatus for manufacturing a package which can be easily opened only by folding in a half-folded state, and can be filled with a filling material in a filling state. be able to.

That is, although the cut 23 is formed to be able to penetrate in the thickness direction T by bending the sheet member 20, since the cut 23 is sealed by the sealing material 35 bonded so as to cover the cut 23, A package 10A having good moisture permeability, gas permeability, and tear-openability can be obtained.
In addition, the sealing material 35 may be pasted so that only the part which formed the notch | incision 23 with respect to the surface of the sheet member 20 may be covered.

The method of taking out the filling object C from the package 10A configured as described above will be described.
The package 10A is held in a state where the lid 13 is directed downward and is folded in two, and the cut 23 of the lid 13 (sheet member 20) is opened and bonded so as to cover the cut 23. The sealing material 35 is broken open (see FIGS. 3A and 3B).

  In more detail, the front side of the lid 13 (surface packaging material 413) to which the sealing material 35 of the sheet member 20 is attached is the outer side, and the filling material C in the main body 12 (back surface packaging material 412) is Hold the filled portion 14 so as to be inside and fold it in half, and open the notches 23 of the sheet member 20 so that the end face of the notches 23 is exposed outward (see FIG. 4) .

  At the same time, the sealing material 35 bonded so as to cover the cut 23 is pulled in the bending direction G by the exposure of the end face of the cut 23, but the sealing material 35 is formed of an aluminum foil which does not easily stretch. The tensile force in the bending direction G causes elongation to some extent, but since the elongation of the sealing material 35 becomes a limit while the sheet member 20 is folded in half, the sealing material 35 is stretched and cut off It is broken open (see FIG. 4).

  Since the thickness of the sealing material 35 is thinner than the thickness of the sheet base 20 a of the sheet member 20, the sealing material 35 bonded so as to cover the cut 23 is folded by folding the sheet member 20 in half. It is fully stretched by the tensile force in the bending direction G, and is broken open in an arc along the curved side edge of the cut 23 (see FIG. 4).

  Further, an arc-shaped projecting portion projecting in an arc shape toward one end side in the longitudinal direction L in the cut 23 is made to protrude outward beyond the bent portion 15 of the sheet member 20, and the seal is stuck so as to cover the cut 23. The fastener 35 is broken open from the inside as shown in FIG. 4.

  As a result, in order to tear open the sealing material 35 bonded to cover the cut 23 in an arc along the curved side edge of the cut 23, the cut 23 is filled in the filling portion 14 with the material C to be filled C Can be reliably opened to a size that allows removal of

  After the slit 23 is broken and opened, the entire package 10A is folded in two and the entire filling portion 14 is deformed so as to crush the filling material C filled in the filling portion 14 is broken and opened. It pushes out from the cut 23 and uses the necessary amount.

  As described above, the size of the cut 23 of the sheet member 20 is such that the removal of the material to be filled C filled in the filling portion 14 is permitted only by bending the package 10A in half by the user's finger. Can be easily and easily broken and opened, and only the necessary amount can be taken out smoothly from the cut and opened incision 23.

While inserting, it forms in the length which extends in the filling part 14 of the back packaging material 412 clamped by a pair of vertical seal roll 441 in the vertical sealing apparatus 44 (refer FIG. 8, FIG. 11).

  The vertical sealing device 44 sandwiches overlapping portions on both sides of the packaging materials 412 and 413 on both sides in the width direction W, and the overlapping portions on both sides of the packaging materials 412 and 413 are longitudinal directions. A pair of vertical seal rolls 441 (rotary type) heat-seal to L is provided (see FIGS. 5 and 8).

  On the circumferential surface of both end portions of the vertical seal roll 441 in the axial direction, vertical pressing portions 442 for heat sealing the overlapping portions on both sides of the packaging materials 412 and 413 are continuously formed in the circumferential direction. A concave groove portion 443 is formed in the circumferential direction on the circumferential surface of the central portion in the axial direction of the vertical seal roll 441 in which the insertion of the filling portion 14 in the back surface packaging material 412 is permitted (see FIG. 8).

  When vertically sealing the overlapping portions on both sides of the packaging materials 412 and 413 with each other in the feed direction F using the above-described longitudinal sealing device 44, the packaging materials 412 and 413 which are superimposed on each other by the packaging material feeding device 43 are It is sandwiched between a pair of vertical seal rolls 441 which are synchronously rotated in the feed direction F by a motor (not shown).

  While vertically feeding the packaging materials 412 and 413 toward each other in the feed direction F by the rotation of the longitudinal sealing roll 441, overlapping portions of the packaging materials 412 and 413 on the both sides, which are superimposed on each other, The heat welding is performed in the feeding direction F (or the longitudinal direction L) by the pressing portion 442 and the longitudinal sealing is performed (see FIG. 8).

  Thus, the vertical sealing portion 415 is continuously formed in the longitudinal direction L along the overlapping portions on both sides of the packaging materials 412 and 413, and the overlapping portions on both sides of the packaging materials 412 and 413 are longitudinal. A cylindrical (tube-like) cylindrical packaging body 414 formed by sealing is continuously formed in the longitudinal direction L (see FIG. 5).

  The cross-sectional shape of the filling pipe 439 may be formed flat in the width direction W, and the lower end of the filling pipe 439 having a flat cross-sectional shape is inserted deeper than the insertion of the filling pipe 439 having a round cross-sectional shape As a result, the overlapping portions on both sides of the packaging materials 412 and 413 can be heat-sealed smoothly by the pair of vertical seal rolls 441.

  The lateral sealing device 45 sandwiches overlapping portions of the packaging materials 412 and 413 corresponding to the spaces between the filling portions 14 in the cylindrical packaging body 414 and heats the overlapping portions in the width direction W with a pair of lateral surfaces. A seal roll 451 (rotary type) is provided (see FIGS. 5 and 9).

  On the circumferential surface of the transverse seal roll 451, a transverse pressing portion 452 for heat sealing in the width direction W the overlapping portions of the packaging materials 412 and 413 corresponding to the space between the filling portions 14 formed on the back surface packaging material 412 A plurality of the seal rollers 451 project outward in the radial direction of the horizontal seal roll 451, and are disposed at predetermined intervals in the circumferential direction corresponding to the spaces between the filling portions 14 in the back surface packaging material 412 (see FIG. 9).

  Between the lateral pressing portions 452 formed on one of the horizontal seal rolls 451, concave grooves 453 are formed in which the filling of the filling portion 14 formed on the back surface packaging material 412 is permitted. Between the lateral pressing portions 452 formed on the other lateral seal roll 451, concave grooves 455 are formed in which the sheet member 20 adhered to the film member 30 in the back surface packaging material 412 is allowed to be fitted ( See Figure 9).

  When horizontally sealing the overlapping portions of the packaging materials 412 and 413 in the cylindrical package 414 in the width direction W using the above-described horizontal sealing device 45, the cylindrical package 414 vertically sealed by the vertical sealing device 44. Is sandwiched between a pair of horizontal seal rolls 451 synchronously rotated in the feed direction F by a motor (not shown).

  While vertically feeding the cylindrical packaging body 414 in the feeding direction F by the rotation of the pair of horizontal seal rolls 451, it corresponds to the space between the filling portions 14 in the packaging materials 412, 413 with which the material C is filled. The upper and lower overlapping portions are pressed and held in the overlapping direction by the lateral pressing portions 452 of the pair of horizontal seal rolls 451, and the overlapping portions are thermally welded in the width direction W and transversely sealed (see FIG. 9) .

  As a result, the lateral seal portion 416 is formed in the upper and lower overlapping portions corresponding to the space between the filling portions 14 in the packaging materials 412 and 413, and the filling portion 14 isolated by the upper and lower lateral seal portions 416 is A large number of members are formed at predetermined intervals in the longitudinal direction L (see FIG. 9).

  The dividing device 46 faces the rotary type rotary blade 461 and the rotary blade 461 for dividing the cylindrical package 414 vertically sealed and transversely sealed by the above-mentioned sealing devices 44 and 45 into individual packages 10A. And a receiving roll 464 (see FIGS. 5 and 10).

A disk-shaped longitudinal blade 462 is formed continuously in the circumferential direction on the circumferential surface of both end portions of the rotary blade 461 in the longitudinal direction L so as to divide the longitudinal sealing portion 415 of the cylindrical package 414. On the circumferential surface of the central portion in the axial direction, a horizontal blade 463 for dividing the transverse seal portion 416 of the cylindrical package 414 in the width direction W orthogonal to the longitudinal direction L and the transverse seal portion 416 of the cylindrical package 414 Correspondingly, a plurality of members are arranged at predetermined intervals in the circumferential direction.
The portion of the receiving roll 464 against which the blades 462 and 463 of the rotary blade 461 are pressed is formed to have substantially the same hardness as the blades 462 and 463.

  When the cylindrical packaging body 414 is divided into individual packaging bodies 10A using the above-described dividing device 46, the cylindrical packaging body 414 vertically sealed and transversely sealed by the sealing devices 44 and 45 is fed by a motor (not shown) It is sandwiched between the rotary blade 461 and the receiving roll 464 which are synchronously rotated in the direction F.

  While longitudinally feeding the cylindrical package 414 in the feed direction F, the vertical seal portion 415 and the horizontal seal portion 416 of the cylindrical package 414 are divided by the vertical blade 462 and the horizontal blade 463 of the rotary blade 461.

  That is, the vertical seal portion 415 of the cylindrical package 414 is continuously divided in the longitudinal direction L by the vertical blade 462 of the rotary blade 461. At the same time, the horizontal seal portion 416 of the cylindrical package 414 is sequentially divided in the direction orthogonal to the longitudinal direction L by the horizontal blade 463 of the rotary blade 461.

  The longitudinal blade 462 of the rotary blade 461 is located inside the widthwise direction W from both side edges in the cylindrical package 414, and a portion outside the widthwise W from the side edges of the filling portion 14 formed in the cylindrical package 414 It is divided in the longitudinal direction L.

  In the space surrounded by the vertical blade 462 and the horizontal blade 463, for example, a heat insulating material such as glass wool may be loaded, and when dividing the vertical seal portion 415 and the horizontal seal portion 416 in the cylindrical package 414. The heat of the rotary blade 461 is less likely to be conducted to the material to be filled C filled in the filling portion 14 of the package 10A, and the material C to be filled can be prevented from being degraded by heat.

  Below the dividing device 46, a remaining piece collecting portion 466 is disposed which rolls around and collects the remaining pieces 417 after the package 10A is separated from the cylindrical package 414 by the dividing device 46. (See Figure 5).

  The feed adjustment device 47 shifts the mark detectors 472 and 473 for detecting the positioning marks 412a and 413a attached to the back surface packaging material 412 and the front surface packaging material 413 and the positioning marks 412a and 413a detected by the mark detectors 472 and 473. According to the determination result by the determination unit 474 which determines whether or not the deviation is less than the threshold by comparing the threshold with a preset threshold, the forming drum 422, the feed roll 431, and the vertical seal according to the determination result A roll 441, a horizontal seal roll 451, and a control unit 475 for controlling the motor rotation of the rotary blade 461 are provided (see FIGS. 5, 8 and 11).

  The positioning marks 412a and 413a are attached to one side edge portions of the front packaging material 413 and the back packaging material 412, and are disposed in a large number at predetermined intervals in the longitudinal direction L of the packaging materials 412 and 413.

  The mark detectors 462 and 463 for detecting the positioning marks 412a and 413a are disposed to face the positioning marks 412a and 413a attached to one edge of the packaging material 412 and 413 (FIG. 5, FIG. 8, FIG. 11).

  The positioning mark 412 a is attached to a position corresponding to the central portion in the longitudinal direction L of the filling portion 14 formed on the back surface packaging material 412. The positioning mark 413a is attached at a position corresponding to the central portion in the longitudinal direction L of the sheet member 40 bonded to the film member 30 constituting the front packaging material 413 (see FIGS. 8 and 11).

  The determination unit 474 determines the displacement generated in the feeding direction F of the packaging materials 412 and 413 based on the detection signals output from the mark detectors 472 and 473, and the packaging materials 412 and 413 have the feeding direction F. It is determined how much the time has passed with respect to H. Or, how long a delay has occurred with respect to the feed direction F (see FIGS. 8 and 11).

  The control unit 475 incorporates a CPU, a ROM, and a RAM (not shown). The CPU drives, stops, and stops the forming drum 422 in the manufacturing apparatus 40, the feed roll 431, the vertical seal roll 441, the horizontal seal roll 451, and the rotary blade 461 according to the program stored in the ROM. The rotational speed is controlled (see FIGS. 8 and 11).

  The CPU compares the displacement between the positioning marks 412a and 413a attached to the packaging materials 412 and 413 with the threshold value stored in advance on the basis of the detection signals output from the mark detectors 472 and 473, and It is determined whether or not the deviation between the positioning marks 412a and 413a attached to the packaging materials 412 and 413 is less than a threshold.

The manufacturing method which manufactures the package 10A which can be broken open using the manufacturing apparatus 40 comprised as mentioned above is demonstrated.
The manufacturing method includes an overlapping step a in which the back packaging material 412 and the front packaging material 413 supplied from the packaging material supply devices 41 and 42 are vertically fed by the packaging material feeding device 43 in the feeding direction F; A vertical sealing step b of heat sealing the overlapping portions on both sides of the packaging materials 412 and 413 in the longitudinal direction L with the longitudinal sealing device 44, and overlapping portions corresponding to between the filling portions 14 in the packaging materials 412 and 413 A sealing step c of heat sealing in the width direction W by the horizontal sealing device 45, a filling step d of filling the object C into the tubular package 414 from above by the filling device 438, and a sealing step b , C, and a dividing step e of separating the cylindrical package 414 vertically sealed and horizontally sealed into individual packages 10A by the dividing device 46 in this order (see FIG. 5).

  In the overlapping step a, the back packaging material 412 and the front packaging material 413 supplied from the packaging material supply devices 41 and 42, the part of the back packaging material 412 opposite to the part where the filling portion 14 is formed, and the front packaging material The sheet member 20 is sandwiched from above between a pair of feed rolls 431 in the packaging material feeding device 43 while overlapping the portion where the sheet member 20 of the film member 30 is pasted together and the opposite side to each other. The sheet is longitudinally fed in the feed direction F by the rotation of the feed roll 431, and is supplied to the vertical sealing device 44 of the vertical sealing step b (see FIGS. 5 to 8).

  In the vertical sealing step b, the overlapping portions on both sides along the feed direction F in which the packaging materials 412 and 413 overlap with each other are sandwiched from above between the pair of vertical sealing rolls 441 in the vertical sealing device 44 While the seal roll 441 is rotated, it is thermally welded and longitudinally sealed while being longitudinally fed in the feed direction F (see FIGS. 5 and 8).

  Vertical seal portions 415 formed by thermally welding overlapping portions on both sides of the packaging materials 412 and 413 are continuously formed in the feed direction F along the overlapping portions on both sides of the packaging materials 412 and 413, The cylindrical packaging body 414 formed into a cylindrical (or tube-like) shape by pasting together overlapping portions on both sides of the packaging materials 412 and 413 is supplied to the horizontal sealing device 45 in the horizontal sealing step c (see FIG. 5) .

  When vertically sealing the overlapping portions of the packaging materials 412 and 413 with each other by the vertical sealing device 44, the positioning detectors 412 and 473 detect the positioning marks 412a and 413a attached to the packaging materials 412 and 413, respectively. Whether the deviation between the positioning marks 412a and 413a is less than the threshold by comparing the deviation between the mark detectors 472 and 473 detected by the mark detectors 472 and 473 with the threshold set in advance by the determination unit 474 It is determined by the determination unit 474 whether the determination is made (see FIG. 8).

  The displacement generated in the feeding direction F between the packaging materials 412 and 413 may be a fluctuation or a slip of the transfer force generated when the packaging materials 412 and 413 are transferred in the feeding direction F by the rotation of the feed roll 431. It is caused by the expansion and contraction that occurs in the longitudinal direction L of itself.

  However, even if misalignment occurs between the packaging materials 412 and 413, the misalignment between the positioning marks 412a and 413a is also small if misalignment adjustment is not necessary, so the determination unit 474 determines that the envelopes of the positioning marks 412a and 413a deviate from each other. Is less than the threshold value, and it is determined that the adjustment of misalignment between the fittings 412 and 413 is unnecessary (see FIGS. 8 and 11).

  When it is determined that the misalignment adjustment is not necessary, the portion of the back surface packaging material 412 opposite to the portion where the filling portion 14 is formed and the surface packaging material 413 opposite to the portion where the sheet member 20 of the film member 30 is bonded The wrapping materials 412 and 413 are longitudinally fed by the wrapping material feeding device 43 in the feeding direction F while the parts are superimposed in a mutually opposing state, and the overlapping portions on both sides of the wrapping materials 412 and 413 are It heat-seals in the feed direction F by the vertical sealing apparatus 44 of the vertical sealing process b, and bonds together integrally (refer FIG. 8, FIG. 11).

  If the misalignment between the packaging materials 412 and 413 is large enough to require misalignment, the misalignment between the positioning marks 412a and 413a is also large, so the determination unit 474 determines that the misalignment between the positioning marks 412a and 413a is equal to or greater than the threshold. It is determined that the misalignment adjustment of the packaging materials 412 and 413 is necessary (see FIGS. 8 and 11).

  When it is determined that the misalignment adjustment is necessary, the control unit 475 causes the rotation of the pair of feed rolls 431 in the packaging material feeding device 43 and the pair of vertical seal rolls in the vertical sealing device 44 based on the determination result by the determination unit 474. The rotation of 441 is controlled, and the packaging materials 412, 413 are fed and adjusted so that the positioning marks 412a, 413a coincide with each other (see FIGS. 8 and 11).

  Specifically, the rotational speed of one of the vertical seal rolls 441 corresponding to the packaging material in which the packaging materials 412 and 413 are shifted is made slower than the rotational speed of the other vertical seal roll 441 or faster. And the rotation is stopped, and the packaging materials 412 and 413 are fed and adjusted so that the positioning marks 412a and 413a coincide with each other (see FIGS. 8 and 11).

  As a result, it is not necessary to adjust the misalignment of the marks and patterns printed on the packaging materials 412 and 413, the misalignment of the sealing position to be heat sealed by the sealing device 45, the misalignment of the dividing position to be divided by the dividing device 46, etc. The overlapping portions on both sides of the packaging materials 412 and 413 can be heat sealed in the feed direction F by the vertical sealing device 44 and integrally bonded (see FIGS. 8 and 11). .

  In the filling step d, the cylindrical packaging body 414 formed into a cylindrical shape by laminating overlapping portions on both sides of the packaging materials 412 and 413 is fed from the filling pipe 439 of the filling device 438 while longitudinally feeding in the feeding direction F. The to-be-filled material C is filled from above into the cylindrical package 414, and the cylindrical package 414 filled with the to-be-filled material C is supplied to the transverse sealing device 45 of the transverse sealing step c (FIG. 5) reference).

  In the horizontal sealing step c, the overlapping portion of the packaging materials 412 and 413 corresponding to the space between the filling portions 14 in the cylindrical packaging body 414 supplied from the vertical sealing step b is the horizontal sealing roll 451 in the horizontal sealing device 45. While being longitudinally fed in the feed direction F by rotation of the horizontal seal roll 451, the sheet is heat-welded sequentially from the bottom in the width direction W and laterally sealed (see FIGS. 5 and 9).

  The cylindrical packing body 414 is longitudinally fed in the feeding direction F by the transport amount by which one package 10A is longitudinally fed by the packaging material feeding device 43, and the previous filling portion 14 filled with the material C to be filled. Is moved downward, and the next filling section 14 is moved to a position where filling of the object C by the filling device 438 is permitted (see FIG. 9).

  When the lower overlapping portion (portion corresponding to the bottom) in the next filling portion 14 is heat sealed by the lateral sealing device 45, the upper overlapping portion in the previous filling portion 14 is also heat sealed to be filled. The lower and upper overlapping portions of the filling portion 14 filled with the object C are sealed by the lateral seal portion 416 (see FIG. 9).

  Thereby, the filling part 14 in which the material to be filled C is filled is separated individually by the upper and lower horizontal seal parts 416, and the filling part 14 in which the material to be filled C is filled is a cylindrical package 414. The cylindrical packaging body 414, which is formed in a large number at predetermined intervals in the longitudinal direction L in the above, and which is longitudinally sealed and transversely sealed in the sealing steps b and c, is supplied to the dividing device 46 of the dividing step e (see FIG. 5) .

  In the dividing step e, the cylindrical package 414 supplied from the side sealing step c is sandwiched between the rotary blade 461 and the receiving roll 464 in the dividing device 46 from above, and by rotation of the rotary blade 461 and the receiving roll 464 While vertically feeding in the feed direction F, the vertical seal portion 415 and the horizontal seal portion 416 of the cylindrical package 414 are divided by the vertical blade 462 and the horizontal blade 463 of the rotary blade 461 (see FIGS. 5 and 10). .

That is, the vertical seal portion 415 of the cylindrical package 414 is continuously divided in the longitudinal direction L by the vertical blade 462 of the rotary blade 461, and the horizontal seal portion 416 of the cylindrical package 414 is It divides | segments into the width direction W sequentially from the bottom by the blade 463 (refer FIG. 10).
Thereby, the cylindrical package 414 is separated into individual packages 10A filled with a predetermined amount of the material to be filled C (see FIG. 1).

  As a result, it is possible to easily break and open by simply folding in a half-folded state, and it is possible to continuously produce many packages 10A filled with the material to be filled C in a state where the inside of the filling portion 14 is filled.

  Further, since the overlapping portions of the packaging materials 412 and 413 are thermally welded while being longitudinally fed in the feeding direction F, the overlapping portions of the packaging materials 412 and 413 can be thermally welded stably at high speed. For this reason, manufacturing efficiency can be improved by manufacturing package 10A using the manufacturing method and the manufacturing apparatus 40 of Example 1.

  Moreover, since the overlapping portions on both sides of the packaging materials 412 and 413 are melted and thermally welded to each other by the vertical sealing device 44, for example, if the deviation is about + -1% to + -5%, the overlapping portions The package materials 412 and 413 can be moved relative to each other in the feed direction F by using the melting of

  That is, the rotational speed of one of the vertical seal rolls 441 corresponding to the packaging material of the packaging materials 412 and 413 which has shifted is made slower or faster than the rotational speed of the other vertical seal roll 441, or By stopping the rotation and moving the packaging materials 412 and 413 relative to each other in the feed direction F, the misalignment between the packaging materials 412 and 413 can be easily adjusted (see FIG. 8).

  Furthermore, the overlapping portion corresponding to the space between the filling portions 14 in the cylindrical packaging body 414 is sequentially pressed from the bottom by the lateral pressing portion 452 of the horizontal seal roll 451 to be filled in the cylindrical packaging body 414. While pushing up the object C upward, the overlapping portions corresponding to the spaces between the filling portions 14 in the cylindrical package 414 are heat-welded sequentially from the bottom.

  In other words, even if air remains in the filling unit 14, heat sealing is performed while pressing upward from the bottom by pressing sequentially from the bottom by the lateral pressing units 452 of the pair of horizontal seal rolls 451, so air is unlikely to remain in the filling unit 14 A predetermined amount of the material to be filled C can be reliably filled in a state in which the inside of the filling portion 14 is filled (see FIG. 9).

  As a result, the material to be filled C filled in the filling portion 14 of the package 10A can be prevented from being denatured (oxidized) by air, and the quality of the material to be filled C can be guaranteed for a long time.

  Furthermore, the outer peripheral edge portion of the film member 30 whose thickness outside the outer peripheral edge portion of the sheet member 20 in the surface packaging material 413 is thin, and the back surface packaging whose film thickness outside the outer peripheral edge portion of the sheet member 20 is thin The overlapping portion of the material 412 with the outer peripheral edge is heat welded by the sealing devices 44 and 45 in the sealing steps b and c.

  For example, the heat welding time required for heat welding is shorter and the amount of heat consumed is smaller if the thin outer peripheral portions of the films are heat welded to each other than the heat peripherally bonding the thick outer peripheral portions of the sheets. It is finished.

  Therefore, while being able to shorten welding time at the time of performing vertical seal and horizontal seal by seal device 44 and 45 sharply, the cost which manufacture of package 10A requires can be reduced sharply.

  Hereinafter, the manufacturing method of the above-mentioned package 10A and the other example of the manufacturing apparatus 40 are demonstrated. In this description, the same or equivalent parts as those in the above-described configuration are denoted by the same reference numerals, and the detailed description thereof is omitted.

(Example 2)
Although the above-mentioned Example 1 demonstrated the example which bonded the sealing material 35 together on the surface of the sheet | seat member 20 in the surface packaging material 413 in 10 A of packages, as shown in FIG. The surface packaging material 413 of Example 2 which made the peripheral part 35a of this bite bite in the surface of the sheet member 20 is demonstrated.

  FIG. 12 is an explanatory view of the surface packaging material 413 of Example 2 in which the sealing material 35 is cut into the surface of the sheet member 20. More specifically, FIG. 12A is a sheet of the peripheral portion 35a of the sealing material 35. FIG. 12B is an enlarged cross-sectional view of a pressure bonding method in which the sealing material 35 is heat and pressure bonded to the surface of the sheet member 20. As shown in FIG.

In the surface packaging material 413 of the second embodiment, the outer surface of the sheet member 20 in the thickness direction T coated with the sealing material 35 and the outer surface of the peripheral portion 35 a of the sealing material 35 in the thickness direction T are approximately the same. They are formed to have the same height (see FIG. 12A).
On the back surface side of the sealing material 35, a sealing material 35b for bonding the sealing material 35 to the surface of the sheet member 20 is attached.

  Since the above-described sealing material 35 is made of aluminum foil, if the heating and pressure-bonding device (not shown) is used, the sealing material 35 is heated and pressure-bonded to the sheet member 20 without interposing the bonding sealing material 35b. (See FIG. 12 (b)).

  For example, the sheet member 20 is an A-PET sheet having a thickness of 0.25 mm, the sealing material 35 is an aluminum foil having a thickness of 15 μ, the pressure bonding area is 10 mm × 20 mm, and the heating temperature is The pressurization time is 130 seconds, the pressurization time is 15 seconds (10 mm × 20 mm).

  The sealing material 35 is pressed in a direction (thickness direction T) in which the sealing material 35 is pressed against the surface of the sheet member 20 by the mold 60 provided in the above-described thermocompression bonding apparatus, and the peripheral portion 35a of the sealing material 35 is It bites into the surface of the member 20.

  As a result, the peripheral portion 35a of the sealing material 35 can be more closely adhered and sealed to the surface of the sheet member 20, and the leakage and the outflow of the material C can be more reliably prevented. .

  Specifically, in the surface packaging material 413 of Example 2, the surface of the sheet member 20 on the outer side in the thickness direction T coated with the sealing material 35, and the surface on the outer side of the thickness direction T of the peripheral portion 35a of the sealing material 35 Of the sheet member 20 and the sealing material 35 can be continuous on the outer side in the thickness direction T.

  As a result, it is possible to prevent a step from being produced in the peripheral portion 35a of the sealing material 35 coated so as to cover the cuts 23 in the sheet member 20, and the portion of the sheet member 20 to which the sealing material 35 is attached Even when touched, the fingertip is not caught on the peripheral portion 35a of the sealing material 35, and a good touch feeling can be obtained.

  As a result, for example, dust such as dust and dirt can be prevented from adhering to the peripheral portion 35 a of the sealing material 35, and a hygienic state can be maintained. Since the sealing state by the sealing material 35 is stably obtained, the leakage and the outflow of the material to be filled C can be reliably prevented.

Moreover, for example, even when the packages 10A come into contact with or contact with each other at the time of movement such as transportation or transportation, the corner 35a of the sealing material 35 of the package 10A is a corner of the other package 10A. It is difficult for the edge and the like to abut, and it is possible to reliably prevent, for example, the generation of a tear or a recess or the like in the peripheral portion 35a of the sealing material 35 or the curling up of the peripheral portion 35a of the sealing material 35.
Furthermore, the surface of the sheet member 20 and the sealing material 35 on the outer side in the thickness direction T is continuous and is a smooth and clean surface, so that the external appearance design is improved.

  Furthermore, air tightness is produced by manufacturing the package 10A which can be broken open using the surface packaging material 413 formed by cutting the peripheral portion 35a of the sealing material 35 into the surface of the sheet member 20 as described above. And the package 10A excellent in water tightness can be manufactured more reliably.

(Example 3)
In the first embodiment described above, the package 10A manufactured by heat welding the upper and lower overlapping portions corresponding to the space between the filling portions 14 filled with the material C to be filled in the cylindrical package 414 is welded. As shown in 13, the package 10A of Example 3 manufactured without applying heat to the material to be filled C filled in the filling unit 14 will be described.
FIG. 13 is an explanatory view of a package 10A of Example 3 in which the material to be filled C is filled from the unheated sealed portion.

  The packaging body 10A of Example 3 forms the bag-like shape by heat-welding both sides and the lower overlapping portion in the packaging materials 412 and 413 when the back packaging material 412 and the front packaging material 413 are superimposed on each other. .

  After filling a predetermined amount of the material to be filled C from the opening 10d formed at the upper edge of the unheated welding with respect to the inside of the filling portion 14 of the package 10A, the opening 10d of the package 10A is It adheres and seals with adhesion layer N3 (for example, instant adhesives, solvent system adhesives etc.) applied to the inner wall face of section 10d.

  Thereby, the package 10A filled with the predetermined amount of the material to be filled C can be manufactured without applying heat as much as possible to the material to be filled C. Therefore, the material to be filled C filled in the filling portion 14 Can be prevented from being degraded or deformed by heat. In addition, the package 10A having substantially the same function and effect as the first embodiment can be manufactured.

(Example 4)
In the first embodiment described above, the package 10A in which the back surface packaging material 412 and the front surface packaging material 413 are bonded to each other has been described. However, as shown in FIG. The packaging body 10B of Example 4 comprised with the surface packaging material 413 bonded and formed inside is demonstrated.

  FIG. 14 is an explanatory view of the package 10B of the fourth embodiment formed by folding the film member 30 in half, and in detail, FIG. 14 (a) is a perspective view of the sealed package 10B viewed obliquely from above; (B) is the top view which looked at the package body 10B from the surface side.

  The package 10 </ b> B of the fourth embodiment is manufactured using only the front packaging material 413 without using the back packaging material 412 of the first embodiment. The surface packaging material 413 is formed by bonding a sheet member 20 having a substantially rectangular shape in plan view formed in a size slightly smaller than the packaging body 10B inside the outer peripheral edge of the film member 20 in a two-folded state.

  Further, at both end portions in the width direction W corresponding to the bent portions 15 in the sheet member 20, there are formed recessed portions 24 recessed from the both end portions in the width direction W toward the central portion (FIG. a) see (b)).

  In the case of manufacturing the package 10B, the film member 30 having a substantially rectangular shape in a plan view and having a length approximately twice the length of the sheet member 20 in the surface packaging material 413 is used with the surface on which the sheet member 20 is attached. After being folded in two by the folding means (not shown), the remaining three overlapping parts are heat-welded by the thermal welding means (not shown) except for the bent part formed on one side of the film member 30 (FIG. 14 (a) (b)).

  When taking out the material to be filled C from the package 10B configured as described above, the package 10B is folded in two, and the cut 23 of the sheet member 20 in the surface packaging material 413 is broken open. And the sealing material 35 bonded together so as to cover is broken open (see FIG. 4).

  As a result, since the to-be-filled C filled in the filling portion 14 of the package 10B can be smoothly taken out from the cut and opened notches 23 of the sheet member 20 in the surface packaging material 413, substantially the same as Example 1. The effects and effects of

  In addition, since the angular portion of the peripheral portion of the sheet member 20 is covered with the flexible film member 30, it is possible to prevent the finger from being damaged when, for example, the sheet member 20 is pinched and bent by the finger. Moreover, the effect of relieving the pain felt at the time of bending is obtained, and the feel when touched with a finger is good.

  Furthermore, since the width of the bent portion 15 in the sheet member 20 is narrower than the other portions by the amount of the recessed portion 24, the rigidity of the bent portion 15 is weaker than that of the other portions. The package 10B can be easily bent.

(Example 5)
In the above-described third embodiment, the package 10B formed by bonding the sheet member 20 inside the outer peripheral edge of the film member 30 has been described. However, as shown in FIG. A package 10C according to a fifth embodiment will be described, in which a portion thereof is formed so as to protrude outward from one side edge portion of the main body portion 12 having a bag shape formed by bending the film member 30 in half.
FIG. 15 is a cross-sectional view of the package 10 </ b> C of the fifth embodiment in which a part of the sheet member 20 protrudes outward from one side edge of the main body 12.

The package 10 </ b> C of the fifth embodiment is manufactured using only the front packaging material 413 without using the back packaging material 412 of the first embodiment. The front surface wrapping material 413 is formed by bending one side edge portion (folded portion) of the filling portion 14 having a bag shape formed by bending the film member 30 in half from the central portion in the longitudinal direction L of the sheet member 20. It is formed in the size and shape which project outward.
The left half of the central portion of the sheet member 20 in the longitudinal direction L is attached to the outer surface corresponding to the filling portion 14 of the film member 30 (see FIG. 15).

  When the package 10C is manufactured, the film member 30 in the surface packaging material 413 is folded in half by the folding means (not shown), and the remaining three sides are overlapped except for the folded portion formed on one side of the film member 30. The portion to be joined is heat-welded by a heat-welding means (not shown) to form a bag-like filling portion 14.

  As a result, a package 10C is produced in which a part of the sheet member 20 is formed by bending the film member 30 in a two-folded state and protrudes outward from one side edge of the filling portion 14 (see FIG. 15).

  When taking out the to-be-filled object C from the package 10C configured as described above, the package 10C is folded in two, and the peeling regions 16 corresponding to between the notches 21 and 31 in the members 20 and 30 correspond to each other. The peel-bonded part is peeled open (see FIG. 4).

  As a result, since the to-be-filled C with which the filling part 14 of the package 10C was filled can be smoothly taken out from the peeled and opened part corresponding to between the notches 21 and 31 in the members 20 and 30 Operations and effects substantially equivalent to those of Example 1 can be exhibited.

  Moreover, for example, a hole in which a locking portion (not shown) such as a hook or a pin is locked may be formed in a portion protruding outward from one side edge of the main body 12 in the sheet member 20. In this case, if the hole formed on the protruding side of the sheet member 20 is locked to the above-mentioned locking portion, the package 10C filled with the material C to be filled can be displayed or displayed in a suspended state .

  In the above-described first embodiment, an example has been described in which the surface packaging material 413 in which the sheet member 20 is bonded to the film member 30 is supplied to the overlapping step a in a step separate from the manufacturing apparatus 40. The surface packaging material 413 may be supplied to the overlapping step a while the sheet member 20 is attached to the portion of the film member 30 corresponding to the filling portion 14 of the back surface packaging material 412 as shown in FIG.

(Example 6)
Although the manufacturing method which manufactures the package 10A which can be broken open in the above-mentioned Example 1 was demonstrated, as shown in FIGS. 17-19, the manufacturing method which manufactures peelable package 10D of Example 6 is shown. Will be explained.

  FIG. 17 is an explanatory view of a package 10D which is folded in two, folded and peeled open, and in detail, FIG. 17 (a) is a perspective view of the package 10D seen obliquely from above; FIG. 17 (b) is a package It is the top view which looked at 10D from the surface side.

  18 is an explanatory view of the peeling and opening structure in the package 10D shown in FIG. 17. Specifically, FIG. 18 (a) is a cross-sectional view in which the package 10D is divided at the central portion in the width direction W; FIG. 18 (b) (B) is an enlarged cross-sectional view of a portion b shown in (a), and FIG. 19 is an explanatory view when the material to be filled C is taken out from the package 10D.

The main body portion 12 in the package 10D of the sixth embodiment is configured of a back surface packaging material 412 formed of a film made of a synthetic resin. The lid 13 is formed of a surface packaging material 413 formed by bonding the sheet member 20 to the surface of the film member 30 corresponding to the filling portion 14.
The package 10D is configured by heat-welding the peripheral edge where the thickness of the back surface packaging material 412 in the main body 12 is thin and the peripheral edge where the thickness of the surface packaging material 413 in the lid 13 is thick (FIG. 17) , See Figure 18).

  The package 10D described above is manufactured using the manufacturing apparatus 40 described in the first embodiment, and the configuration and manufacturing method of the manufacturing apparatus 40 are as described in the first embodiment, and thus the detailed description thereof will be described. I omit it.

  The structure of the surface packaging material 413 different from the package 10A of the first embodiment in the package 10D will be described. A peeling area 16 indicated by a two-dot chain line in the figure is set as a area for peeling the sheet member 20 and the film member 30 in the central portion in the longitudinal direction L of the lid 13 (see FIGS. 17 and 18). .

  In the peeling area 16, when the members 20 and 30 are folded in half, arc-shaped notches 21 and 31 penetrated with respect to the thickness direction T of the members 20 and 30 are not illustrated, which are not illustrated. It forms with a punching machine (refer FIG. 17, FIG. 18).

  The notches 21 and 31 are formed in a shape curving in an arc toward one end side of the sheet member 20 and the film member 30 in the longitudinal direction L when the lid 13 is viewed from the surface side, and have the same shape and the same length. Is formed. The cuts 21 and 31 are formed to intersect the longitudinal direction L of the members 20 and 30, and are disposed at a predetermined distance from the longitudinal direction L (FIGS. 17A and 17B, 18 (A) (b)).

  The distance S between the notches 21 and 31 is a distance in the range of about 0.5 times to about 100 times (preferably about 10 times) the thickness of the sheet member 20. The lateral width Wi of the notches 21 and 31 is formed equal to or less than the lateral width (desirably, about 70% or less) based on the lateral width of the sheet member 20 (see FIG. 17B).

  Opposing surfaces in the peeling area 16 corresponding to between the notches 21 and 31 in the sheet member 20 (sheet base 20a) and the film 30 (seal material 30b) are re-peeled by the adhesive layer N1 interposed between the opposing surfaces. It is stuck possible. The facing surfaces of the sheet member 20 and the film member 30 outside the peeling area 16 are adhered so as not to be peeled off by the adhesive layer N2 interposed between the facing surfaces (FIG. 18 (b) and FIG. See the enlarged view of part c)).

  When manufacturing the package 10D described above, by manufacturing the lid 13 using the surface packaging material 413 in which the cuts 21 and 31 are formed, a large number of peelable and openable packages 10D are continuously manufactured. In addition to the above, it is possible to achieve the same effects and effects as those of the first embodiment.

  When taking out the to-be-filled object C from package 10D which comprised the cover part 13 as mentioned above, it hold | maintains the package 10A in the state which the cover part 13 faces downwards, and it folds in 20 parts. The peelably bonded portions in the peeling region 16 corresponding to the spaces between the notches 21 and 31 in the portions 30 can be peeled and opened against the adhesive force of the adhesive layer N1 (see FIG. 19).

  Specifically, the sheet member 20 is held in such a way that the thicker sheet member 20 is on the inside and the film member 30 whose thickness is thinner than the sheet member 20 is on the outside, and the sheet member is folded in half. The curvature radius of the film member 30 is larger than that of the sheet member 20 by the thickness of 20, and the sheet member 20 is compressed and contracted by bending, but the film member 30 is further bent by the tensile force applied to the bending portion 15 It is pulled towards the direction G.

  As a result, the releasably bonded portions in the peeling region 16 of the members 20 and 30 are displaced in opposite directions, so that the releasably bonded portion between the notches 21 and 31 is the adhesive layer It can be peeled and opened against the adhesive force of N1 (see FIGS. 19 (a) and (b)).

  Furthermore, when the package 10D is folded in half, since the arc-shaped tongue pieces 21a and 31a in the notches 21 and 31 obliquely protrude outward, the notches 21 and 31 in the members 20 and 30 are set. In addition to being in communication with the filling portion 14 in which the filling material C is filled, the filling portion 14 can be opened to a size and a shape that allow removal of the filling material C in the filling portion 14 (FIG. 19 (b )reference).

  As a result, only by bending the package 10D in a half-folded state, the portions corresponding to the portions between the notches 21 and 31 in the members 20 and 30 can be peeled off easily and easily, and the filling portion 14 is filled. The material to be filled C can be smoothly taken out from the peeled and opened portion between the notches 21 and 31.

Moreover, when the peelably bonded portion between the notches 21 and 31 is peeled and opened, the material C to be filled which is pushed out from the notches 21 and 31 is pushed out while being in contact with the tongue portions 21a and 31a (FIG. b) see).
Thereby, the to-be-filled substance C with which the filling part 14 of package body 10D was filled can not be easily pushed out at once, and it can prevent that the to-be-filled substance C splashs around.

  Furthermore, since the gaps 21 and 31 formed in the members 20 and 30 are separated by an interval included in the range of about 0.5 times to about 100 times the thickness of the sheet member 20, the slits 21, It is possible to secure a bonding area necessary for bonding in a state of being in close contact with each other on the facing surfaces of the sheet member 20 and the film member 30 corresponding to the gap 31.

  Furthermore, the incisions 21 and 31 formed in the members 20 and 30 do not communicate with each other until the peelably bonded portions in the peeling region 16 of the members 20 and 30 are peeled and opened. It can be reliably prevented that the to-be-filled thing C with which the filling part 14 of package 10D was filled leaks from the incisions 21 and 31. As shown in FIG.

  Furthermore, due to the internal pressure of the material to be filled C filled in the filling portion 14, the peelably bonded portions in the peeling region 16 in the members 20 and 30 are in close contact with each other, for example, by bending or bending. As a result, the material C can be more reliably prevented from leaking.

  Furthermore, when the bending of the package 10D is released, the package 10D returns to the state before the bending by the restoring force of the sheet member 20 itself, so the peeled and opened portion in the peeling area 16 between the members 20 and 30 Can be sealed again by the adhesive layer N1, and can be kept in a state where leakage of the material to be filled C is prevented until peeling and opening again.

  As a result, even if the package body 10D is turned over so that the incisions 21 and 31 are in the horizontal orientation, or if the incisions 21 and 31 are in the downward direction, etc., the outflow or leakage of the material C is minimized. Can be limited.

(Example 7)
In the above-described sixth embodiment, the package 10D manufactured by heat-welding a portion with a small thickness in the back surface packaging material 412 and a portion with a large thickness in the surface packaging material 413 has been described. The package 10E of the seventh embodiment will be described which is manufactured by heat-welding the thin portions of the packaging materials 412 and 413 to each other.

  FIG. 20 is an explanatory view of a package 10E of Example 7 manufactured by heat-welding thin portions of the packaging materials 412 and 413 to each other, and in detail, FIG. 20 (a) shows the width of the package 10E. FIG. 20B is an enlarged cross-sectional view of a portion b illustrated in FIG. 20A, which is a cross-sectional view of a cross-sectional view divided at a central portion in the direction W.

  The package 10E of the seventh embodiment is manufactured by thermally welding peripheral portions outside the sheet member 20 sandwiched between the pair of film members 30 in the packaging materials 412 and 413 to each other. Alternatively, the peripheral portions outside the sheet member 20 bonded to the surface corresponding to the filling portion 14 of the film member 30 in the packaging materials 412 and 413 are thermally welded and manufactured (see FIGS. 20A and 20B). ).

  As a result, the processing time required for heat sealing is shorter when heat welding thin peripheral portions is shorter than thermal welding between the thick peripheral portions in the packaging materials 412 and 413, and the entire manufacturing apparatus 40 is complete. Can be increased, for example, by about 20% to about 50%, so that a large number of packages 10E can be efficiently manufactured continuously.

In correspondence with the configuration of the present invention and the above embodiment,
One packaging material of the present invention corresponds to the surface packaging material 413 of the embodiment,
And so on
The other packaging material corresponds to the back packaging material 413,
The break opening part corresponds to the cut 23,
The packaging material feeding means corresponds to the packaging material feeding device 43,
The vertical sealing means corresponds to the vertical sealing device 44,
The lateral sealing means corresponds to the lateral sealing device 45,
The dividing means corresponds to the dividing device 46,
The deviation adjustment means corresponds to the feed roll 431, the vertical seal roll 441, and the control unit 475,
The mark detection means corresponds to the mark detectors 431, 432,
The determination unit corresponds to the determination unit 474, but
The present invention is not limited to only the configuration of the above-described embodiment, but can be applied based on the technical idea shown in the claims, and many embodiments can be obtained.

  For example, the folding ruled line may be provided in the width direction Y close to both ends of the notches 23 in the packages 10A to 10C, because the folding resistance at the time of folding the packages 10A to 10C in two is reduced. As well as being able to be easily folded in a two-folded state, the tearing-open of the incisions 23 and the sealing material 35 can be easily performed. In addition, the folding ruled line may be provided in the width direction Y so as to be close to both ends of the notches 21 and 31 in the packages 10D and 10E.

  Further, in a process different from the manufacturing apparatus 40, for example, the belt-like back surface packaging material 412 in which the filling portion 14 is formed is wound in a roll and is loaded in the roll loading unit 421 in advance. You may supply from the roll loading part 421 to the vertical sealing process b.
