Summary of the Invention

Problems to be Solved by the Invention

[0007] For a disposable bag body formed of a resin film in the prior art and a bag body with a zipper, when the user cuts out the contents from the notch of the disposable bag, the opening opens. In order to remove the upper part of the bag with a zipper, the part near the notch provided in the vicinity is pinched with a finger and a force is applied in the continuous longitudinal direction of the zipper to tear it off. Both of them provide an opening by pinching the upper sides of both sides of the longitudinally torn opening in the direction perpendicular to the upper sides with the left and right fingers.

[0008] However, since the lengths of the notched sides that are cut out and extend in the longitudinal direction and the upper sides that are torn off longitudinally from the notch along the zipper are the same continuous sides for both, it is difficult to pinch the upper sides of both sides of the longitudinally torn opening with fingers to open it, whether for the elderly or young, men or women, or for those with long fingernails for women's adornment or for the fingertips that are numb in winter. It is difficult to provide an opening by pinching the upper sides with the left and right fingers in the direction perpendicular to the upper sides of both sides. Therefore, an improvement is needed to efficiently obtain an opening that can be opened on the cut upper side. Therefore, an improvement is required to efficiently obtain an opening that can be easily opened on the cut upper side.

[0025] Fig. I in Fig. 2 is a front view having a remaining side 29 where the upper sealing side 2 of the space 12 is cut off along the cut line 56 from the left notch 9 on the left sealing side 4 to the right notch 10 on the right side 5.

[0026] The space 12 of the bag body 1 has a zipper sealing side 44 where a zipper 43 aligned with the upper sealing side 2 and the longitudinal direction 48 is provided on the zipper tape 11 of the resin film 7 on the A side and the resin film on the B side that are bonded together, and is configured in a state surrounded by a plurality of sealing sides where the left and right sealing sides 4, 5 having the left and right notches 9, 10 in the range direction 36 are arranged and each of which is continuous in sealing.

[0027] The space 12 is on the inner surface 54 where the resin film 7 on the A side and the resin film 8 on the B side, which are composed of a plurality and are to be bonded, face each other, and at least one of the resin film 7 on the A side or the resin film 8 on the B side has a concave or convex shape near the cut line 56.

[0028] Furthermore, the zipper seal side 44 having the left and right seal sides 4, 5 arranged vertically in the range direction 36 and the zipper 43 in the longitudinal direction 48 has a space 13 into which the daily necessities 14 can be enclosed and an inlet 45. After enclosing the daily necessities 14 from the inlet 45 into the space 13, each of the lower seal sides 6 has four corners 32 on the outside of the bag body 1 which is surrounded by a plurality of continuous seal sides and hermetically sealed and integrally formed.

[0029] That is, the space 12 having a concave or convex shape on at least one of the two films 7, 8 is surrounded by the zipper seal side 44 having the zipper 43, the seal sides 4, 5 having the notches 9, 10, and the upper seal side 2. When cut along the cut line 56 having the notches 9 to 10 in FIG. I, the shape of the remaining side 29 has a plurality of opposing concave or convex shapes 15 having a gripping a side 30 and a gripping b side 31 shown in the cross section of FIG. E. The resin films 7 on the A side and 8 on the B side can be printed with cutout portions (cut lines 56) on resin films having a straight-line cutting performance in a straight advancing manner.

[0030] Subsequently, the space 13 integrated with the space 12 and the zipper seal side 44 can form a bag body 1 in which the daily necessities 14 are enclosed and sealed in the space 13 surrounded by the left and right seal sides 4, 6 and the lower seal side 6 of a plurality of continuous sides.

[0031] The daily necessities 14 enclosed in the space 13 of the bag body 1 can be medical supplies related to medical treatment, or medical sundries, cosmetics, snacks, food such as oden, etc. not related to medical treatment. It has a film structure such as a vapor deposition film or an aluminum foil film for ensuring the safety, stability, and compliance with the Food Sanitation Law standards of the enclosed daily necessities 14, and has valid data on safety and stability in the Food Sanitation Law or the Pharmaceutical Affairs Law (hereinafter referred to as "product specifications").

[0032] The space 12 is composed of a plurality. The specific configuration of the bag body 1 formed by the resin film on the A side 7 and the resin film on the B side 8 facing each other with a continuous seal side is that any of the bag bodies 1 forming the continuous upper seal side 2, the left seal side 4, the right seal side 5, the left seal side 4 and the right seal side 5, the zipper seal side 44, and are surrounded by a plurality of continuous seal sides respectively.

[0033] Figure O is a side view from the left or right with the notch 9 on the left to the notch 10 on the right cut off along the longitudinal direction 48 of the zipper 43. While the tips of the mutually concave or convex shapes 15 on the inner side 54 of the a-side 30 and the b-side 31 to be pinched of the remaining side 29 face each other, the a-side 30 and the b-side 31 to be pinched are pushed and expanded in the outer direction 51 by the repulsive force 50 that repels the tips of the mutually concave or convex shapes 15, and by further pinching and expanding the a-side 30 and the b-side 31 to be pinched, an opening 46 opened in the direction 53 perpendicular to the zipper 43 is formed.

[0034] Figure E is a detailed cross-sectional view (cross-section A-A´) of the expanding opening 46, and the A side 7 or Since it is provided near at least one cut line 56 on the B surface 8, when the tips of the concave or convex shape 15 facing each other between the A surface 7 and the B surface 8 meet, the space 12 of the concave or convex shape 15 having a distance between the surfaces, and the cut line 56 connecting the notches 9 and 10 to the left seal 4 or the right seal side 5 for cutting off the zipper tape 11 and the upper seal side 2 in parallel to the zipper tape 11, and there is a repulsive force 54 that repels between the surface of the a side 30 and the surface of the b side 31 of the side 29 cut in parallel to the zipper tape 11, having a distance in the outer direction 51.

[0035] The space 13 integrated with the zipper seal side 44 can be sealed by the lower seal side 6 of a plurality of seal sides where the daily necessities 14 are sealed from the sealing opening 45 of the bag body 1 in FIG. 1 to form the bag body 1, and the plurality of sides are continuous or discontinuous (hereinafter referred to as "continuous").

[0036] The space 12 is formed between the resin films of the A surface 7 and the B surface 8, which consists of a plurality, and is surrounded by the upper seal side 2, the left and right seal sides 4 and 5, and the zipper seal side 44 having the zipper 43. It has a distance where the tips of the concave or convex shape 15 near at least one cut line 56 of the resin film of the A surface 7 or the resin film of the B surface 8 meet (hereinafter referred to as "space") 12.

[0037] When the space 12 surrounded by a plurality of continuous seal sides is cut from the left and right notches 9 and 10 along the cut line 56 to the notch in the longitudinal direction 48 along the zipper seal 11, due to the repulsive force 50 where the tips of the concave or convex shape 15 in FIG. E shown on the inner side 54 of the remaining side 29 in FIG. I meet, the a side 30 for picking on the A surface 7 and the b side 31 for picking on the B surface 8 of the remaining side 29 in the longitudinal direction 48 near the zipper 43 are pushed open in the outer direction 51. Therefore, by opening the pushed-open sides 30 and 31 in the direction 53 orthogonal to the picking with the fingers of both the left and right, the zipper 43 can be opened in the short direction orthogonal to the longitudinal direction 48, and the bag body 1 with the opening 46 is obtained.

[0038] Even for the elderly, men and women, or young women decorated at the fingertips, or the fingertips of shivering fingers in winter, an opening can be easily provided.

[0039] When cut from the left notch 9 to the right notch 10 in the longitudinal direction 48, the remaining side 29 has the tips of the concave or convex shapes 15 on the inner side 54 of the A surface 7 and the B surface 8 facing each other. Therefore, the gripping sides 30, 31 of the A surface 7 and the B surface 8 of the cut side 29 have a repulsive force in the short direction orthogonal to the longitudinal direction 48. The zipper 43 on the zipper tape 11 is widened by pinching the gripping sides 30, 31 with the left and right fingers, and an opening 46 is provided. An outlet 52 with an opening 46 having a distance repelled by the repulsive force 50 in Fig. E, which is easy to operate for opening, is configured.

[0040] On the remaining side 29 where the upper seal side 2 in Fig. I is cut off, the repulsive force 50 of the tips of the concave or convex shapes 15 on both the inner sides 54 of the A surface 7 and the B surface 8 shown in Fig. E hitting each other acts in the outer direction 51. The gripping side a 30 and the gripping side b 31 widened in the outer direction 51 can be pinched with both fingers and expanded in the orthogonal direction 53 to have an outlet 52 with an opening 46. The daily necessities 14 in the sealed bag body 1 can pass through the zipper 43 and be taken out by opening and closing multiple times to take out the capacity.

[0041] In Fig. I, when the upper seal side 2 is cut off from the left notch 9 to the right notch 10 and removed, the remaining side 29, on the inner side 54 of the bag body 1 in Fig. E, the repulsive force 50 of the tip of the concave or convex shape 15 of the A surface 7 and the tip of the concave or convex shape 15 of the B surface 8 facing each other and repelling each other, because each of the facing gripping sides 30, 31 acts in the outer direction 51 , it is easy to open with a light pinch and an opening 46 is provided. The same usage of the repulsive force can be performed when cutting from the right notch 10 to the left notch 9 on the right seal side 5.

[0042] The shape 15 of the concave or convex part on the facing resin films of the A surface 7 and the B surface 8 is provided near at least one cut line 56 of the A surface 7 or the B surface 8. Therefore, the shape of the concave and convex part has a direction from the surface 55 of the resin film of the A surface 7 to the inner side 54, and has a direction from the surface 55 of the resin film of the facing B surface 8 to the inner side 54. That the A surface 7 and the B surface 8 face each other means a state where the facing fusion films 49 they have face each other.

[0043] The usage method of the opening 46 to be opened is that when the upper seal side 2 arranged in the longitudinal direction 48 of the zipper 43 extending in the longitudinal direction 48 of any notch 9, 10 of the left and right seal sides 4, 5 is pinched and cut along the cut line 56, and the upper seal side 2 from the left notch 9 extending in the longitudinal direction 48 to the right notch 10 is cut off and removed, in the space 12 where the A surface 7 and the B8 surface of the remaining side 29 in Figure E face each other, the tips of the concave or convex shape 15 of each other's surfaces hit and repel, and there is a repulsive force 50, and the a side 30 to be pinched on the A surface 7 and the b side 31 to be pinched on the B surface 8 have a distance pushed in the outer direction 51 and opened.

[0044] The bag body 1 has a seal side on the B surface 8 facing the A surface 7, which is composed of a seal or an adhesive seal or the like.

[0045] The bag body 1 has a space 13 for enclosing a daily necessity 14 composed of left and right seals 4, 5 and a continuous zipper seal side 44, and a continuous lower seal side 6 on one side can be provided at the seal opening 45 for sealing. That is, the daily necessity 14 is enclosed from the seal opening 45, and the seal opening 45 is a bag body 1 sealed by a continuous or discontinuous (hereinafter referred to as "continuous") seal.

[0046] The bag body is composed of an upper seal side 2 that is continuous with a plurality of seal sides formed by continuous bag making, a left seal side 4 having a left notch 9, a cut line 56 connecting the right seal side 5 having a right notch 10, a zipper seal side 44 of a zipper tape 11 having a zipper 43, a space 12 where the tips of the concave or convex shapes 15 on the inner side 54 face each other, a space 13 for enclosing daily necessities 14, and a lower seal side 6 for sealing the seal inlet 45.

[0047] Describe the manufacturing method of the bag body 1.

[0048] The bag body 1 in Fig. 2 is manufactured by adding a zipper tape side 44 to the manufacturing method of the bag body 1 in Fig. 1. After describing the manufacturing method with the zipper tape side 44 added in Fig. 2, the manufacturing method in Fig. 1 will be described.

[0049] Fig. 4 is a process diagram of the process flow 34 of the manufacturing method of the bag body 1. The order of the process flow 34 has a molding process 58 and then a sealing process 59 after the material supply device 57.

[0050] The material supply device 57 has a zipper tape roll 41, a resin film roll 39 on the A side, and a resin film roll 40 on the B side.

[0051] The position where the materials are installed is such that the zipper tape roll 41 located in the flow direction 34 is sandwiched between the resin film roll 39 on the A side 7 and the resin film roll 40 on the lower B side 8, and is sent to the next molding process 58.

[0052] The molding process 58 is a process of providing a concave or convex shape in the vicinity of the cut line 56 on at least one of the resin film 7 on the A side or the resin film 8 on the B side.

[0053] The shape 15 of the concave or convex part of FIG. P is formed by a roller 33 with the shape of the concave or convex part. The roller 37 with the shape of the concave or convex part on the A surface has the shape 15 of the concave or convex part in the inner 54 direction from the surface 55 of the A surface 7, and at the same time, at the position in the downward direction, the roller 38 with the shape of the concave or convex part on the B surface has the shape 15 of the concave or convex part in the inner 54 direction from the surface 55 of the B surface 8. It is sent to the next sealing process 59.

[0054] The sealing process 59 has equipment of a C roll 16 and a D roll 17 having heat for configuring the product specifications of a plurality of sealing sides of the bag body 1.

[0055] The rolls 16 and 17 have the same specifications and the same circumference, and are in contact with each other at a contact point 19 having a sealer surface 20. That is, the C roll 16 has a rotation direction 22 of C in the extrusion direction 47 while forming the A surface 7 of FIG. N with the C central axis 21 as the axis, and the D roll 17 in contact with it has a rotation direction 24 of D in the extrusion direction 47 while forming the B surface 8 of FIG. N with the D central axis 23 as the axis. By rotating in the extrusion direction 47, the A surface 7 and the B surface are welded and bonded with a fusion film 49 to complete the sealing process and continuously connect the upper sealing side 2 and the left and right sealing sides 4 and 5. A bag body 1 having a roller rotating at the same speed in the extrusion direction 47 in the longitudinal direction 48 and having the same distance on the circumference is sent out from the bag-making machine.

[0056] The A surface 7 and the B surface 8 having the fusion film 49 in FIG. N are formed by being bonded with rolls of the same specification. The bag body 1 has a sealer surface 20, the upper sealing side 2 has an upper sealer surface 25, the left and right sealing sides 4 and 5 have left and right side sealer surfaces 27, the zipper sealing side 44 has a zipper sealing side sealer surface 26, the space region 60 has a continuous sealer surface 25, 26, 27 surface, and the space region 61 is surrounded by the zipper sealing side sealer surface 26 and the left and right side sealer surfaces 27, and has a distance 28 from the sealer surface in the space region 60 and the space region 61.

[0057] The D-roll 17 in contact with the C-roll 16 has a contact point 19, and the temperature control of the space region 60 and the space region 61 in the cylindrical rolls has a structure that can set individual temperatures lower than the seal temperature of the cylindrical rolls.

[0058] The individual structures that can set low temperatures in the space region 60 and the space region 61 have devices that can set individual temperatures different from the temperature setting of the surface 20 of the sealer, the space region 60, and the space region 61, or devices that send external cold air, or heat insulation materials.

[0059] Furthermore, it is desirable that the material having a heat insulation effect in the space region 60 has a jig that presses the surfaces 55 of the A-surface 7 and the B-surface 8 and stabilizes the shape 15 of the concave or convex portion on at least one inner side 54.

[0060] The temperature control of the roller 37 with the concave or convex shape on the A-surface and the roller 38 with the concave or convex shape on the B-surface in the molding process 58 of the concave or convex shape 15 is set to be considerably lower than the temperature of the seal stroke.

[0061] In the molding process 58, for example, it is desirable to set the temperature around 100°C, which is the heat-resistant temperature of polyethylene terephthalate, at which the roller 33 with the concave or convex shape is pressed from polyethylene terephthalate in the direction of polyethylene. At this time, the temperature setting at which polyethylene faces each other at the seal temperature and welds should not be made. It is necessary to verify the speed at which the bag body 1 is formed, the composition of the resin film, and the welding temperature of the fusion film 49.

[0062] Since the temperature for welding the fusion film 49 on the sealer surface of the cylindrical rolls 16 and 17 in Fig. 2 in the sealing process 59 is set at 220°C to 280°C, it is desirable to verify the temperature corresponding to the space region 60 at around 100°C, which is the heat-resistant temperature at which the concave or convex shape 15 formed in the molding process 58 can be stabilized.

[0063] The structure of rolls 16 and 17 has a sealer surface 20 of rolls 16 and 17, an upper sealer surface 25 of the heat-sealing surface, a zip sealer side sealer surface 26, and left and right side sealer surfaces 27. It has a space region 60, a space region 61, and a daily necessities enclosure space 18.

[0064] The temperatures corresponding to the space region 60 and the space region 61 need to be verified and set, for example, around 100 °C, which is the heat-resistant temperature of the fusion film 49.

[0065] To form the bag body 1, the resin film on surface A 7 and the resin film on surface B 8 in Figure N of Figure 2 have a fusion film 49 laminated on their facing surfaces. The mutual fusion films 50 are rotated 22 and 24 in the extrusion direction 47 of the continuous bag body 35 bonded together by sealing heat. The resin film on surface A 7 and the resin film on surface B 8 are bonded together by the contact point 19 of roll C 16 and roll D 17. Surface A 7 is in contact with roll C 16, and surface B 8 is in contact with roll D 17. The inner sides of surface A 7 and surface B 8 are bonded together by heat welding to form the bag body 1.

[0066] Next, in the state where roll D 17 is sandwiched between the zipper tape roll 41, the resin film roll 39 on surface A 7, and the resin film roll 40 on surface B 8 in the downward direction of roll C 16, a bag is formed on the zipper seal side 44 of the zipper tape 11 having a zipper 43.

[0067] In the longitudinal space 12, the shapes of the concave or convex portions 15 of roll C 16 and roll D 17 are positioned such that their tips meet each other. Since the region surrounding the distance between the sealer surface 20 and the bottom surface in the space 12 needs a temperature setting lower than the sealing temperature of the seal side to prevent the welding of the mutual fusion films 49, it is effective to provide an auxiliary jig such as asbestos having a thickness with a heat-resistant effect on the area of the space 12.

[0068] The auxiliary jig in the space 12 between the C roll 16 and the D roll 17 can manually adjust the force applied in the direction from the surface 55 to the inner side 54 of the films 7 and 8 facing each other at the same time. Therefore, the tips of the concave or convex shapes on the resin film of the A side 7 and the resin film of the B side 8 are pressed by the appropriate force from the auxiliary jig that is fitted and fixed in the area of the surface of the space 12 between the two rollers. When the upper seal side 2 is cut off, a strong repulsive force 50 is obtained at the opening 46 of the remaining side 29.

[0069] Describe the manufacturing method of the disposable bag body 1 in FIG. 1.

[0070] The manufacturing method of the disposable bag body 1 in FIG. 1 is a manufacturing method configured by removing the zipper tape side 44 from the manufacturing method of the bag body 1 in FIG. 2.

[0071] Since the manufacturing method in FIG. 1 does not have the configuration of the zipper tape side 44 in FIG. 2, from the process diagram showing the manufacturing method of the bag with a zipper in FIG. 4, the zipper tape roll 41 in the material device 57 is omitted. Furthermore, the zipper seal side part sealer surface 26 on both the C roll 16 and the D roll 17 in the sealing process 59 is omitted, and it is a process diagram excluding the space 12.

[0072] The configuration of FIG. 1 has a lower seal side 6 parallel to the upper seal side 2 in the longitudinal direction 48 and a right notch 10 parallel to the left seal side 4 having a left notch 9 in the range direction 36. The space 13 of the bag body 1 connected by four continuous seal sides has daily necessities 14.

[0073] For making an opening 46 in the bag body 1, it has a cut line 56 from the seal side with a notch on the side to be cut out and removed towards the seal side with a facing notch, and at least one of the resin film 7 on the A side or the resin film 8 on the B side of the bag body 1 has a concave or convex shape near the cut line 56.

[0074] Describe the parts that both further share.

[0075] Both FIGS. 1 and 2 are cross-sectional views (section A-A') near the cut line 56 of the remaining side 29 after the upper seal side 2 is cut off. In FIG. E, at least one of the resin films 7 on the A side or 8 on the B side has a concave or convex shape near the cut line 56.

[0076] The concave or convex shapes on the gripping a-side 30 and gripping b-side 31 of the remaining side 29 are configured such that the tips of each other meet and spread in the short-side direction of the outer direction 51 by the repulsive force 50 from the inner side 54.

[0077] The illustration of the cross-section of FIG. E has a mechanism that can easily provide the opening 46 and open the zipper 43 by opening the gripping a-side 30 and gripping b-side 31 in the short-side direction orthogonal to the longitudinal direction 48.

[0078] The mechanism has a concave or convex shape 15 near at least one of the cut lines 56 of the remaining side 29 of the resin film 7 on the A side or the resin film 8 on the B side near the zipper 43. The repulsive force direction 50 where the concave or convex shapes meet between the opposing A side 7 and B side 8 acts to easily provide the opening 46 in the short-side direction.

[0079] Furthermore, in the mechanism where the middle part of the repulsive and meeting gripping a-side 30 and gripping b-side 31 is gradually opened wider, since the concave or convex shape has a small shape near both of the left and right notches 9 and 10 at the ends and is provided with a gradually larger shape towards the middle, the distance that spreads to the sides 30 and 31 of each other makes it easy to open with fingers.

[0080] The bag body 1 is formed by a roll type or flat plate type having a heat sealer. The continuous leading bag body 1 sent out in the extrusion direction 47 from the bag-making machine is cut into sheets by a cutter roll from the next bag body 1. Furthermore, the notches 9 and 10 on the left and right seals 4 and 6 and the hanging holes 3 that can be sold with hooks at the store, and the notches 9, 10, and 3 can reduce costs by in-line processing.

[0081] The bag body 1 of the present invention is formed into M pieces of bag bodies 1 by rotating a heat roll for bag making once or operating a hot plate up and down once.

[0082] When notching from the left notch 9 to the right notch 10, a film structure with a processing film having a notchable linear cutting performance on the resin film is desired. There is no problem even if it is cut with scissors in a printed display from the left notch 9 to the right notch 10 of the cut line 56.

[0083] A continuous bag body 1 with a width of 42 having a sealing inlet and a range direction 36 is subjected to a cutting process and a notching process using a cutting blade such as a circle for each sheet. An in-line process that can reduce costs is desired. In addition to the process diagram of the present invention, it can be configured.

[0084] Household goods cover a wide range of daily necessities such as toilet paper, medical supplies, medical sundries, cosmetics, sanitary products, household paper, foodstuffs, and goods related to animals and plants, including those for makeup, nursing care, or wiping the body. It is possible to enclose necessary supplies for life such as dry tissue paper, wiping sheets for makeup use, cosmetic sundries such as cotton puffs, wiping towels for nursing care use, tissue paper, body wiping paper towels, litter paper, kitchen paper, toilet paper, medical supplies corresponding to sterilization, gauze for medical sundries, non-woven fabric sheets, napkins, wiping sheets, and oden with juice.

[0085] Furthermore, it has a moisturizing agent (liquid) for giving moisture to the skin during use, and the efficacy and effect of makeup can be obtained, or a poultice for absorbing the body temperature of the affected part, or supplies for relieving indirect fatigue or muscle fatigue (such as a gel sheet), or a base for preventing hay fever.

[0086] The laminated body to be enclosed is, for example, a laminated body in which each tissue paper or blotting paper is folded and laminated in a pop-up manner, or a laminated body in which each tissue paper or blotting paper is folded and laminated (hereinafter referred to as "laminated body"). Globular cotton balls or small cut cosmetic cotton that are difficult to work with for lamination are enclosed in the bag body 1 in a filled state or arranged side by side.

[0087] The selection of the resin film forming the bag body 1 is arbitrary. For example, it is composed of a resin film having a barrier property corresponding to daily necessities that can withstand the stability tests of the Food Sanitation Law or the Pharmaceutical Machinery Law. The resin film is desired to have a configuration with thickness or single or multiple constituent films or metal foil or vapor deposition, etc., and to have the safety and stability of the contents in an unopened state.
