Description

  The present invention relates to a pouch with a zipper that can be resealed after opening and a method for manufacturing the same.

  Zippered pouches are conventionally used as packaging bags for various contents such as foods, drinks, detergents, and pharmaceuticals. It is important that such a zippered pouch can be resealed and the filled contents are securely sealed. This zippered pouch has a single plastic film folded vertically or horizontally, or a pair of film materials facing each other, the top and bottom seals at the top and bottom edges, and the side seals at both edges It is manufactured by cutting a peripheral seal such as a bag after cutting it.

  At this time, the pouch has a zipper having male and female portions that can be fitted to each other, and is attached to the inside of the top seal portion. That is, a zipper is sandwiched between film materials, and the zipper is sealed to each film material while intermittently feeding them out. Since the end of this zipper overlaps with the side seal etc., the end of the zipper is crushed in advance, and the seal is applied by the heat seal bar over the crushed area, and the side seal part etc. is formed Yes.

  However, the seal bar may be displaced due to meandering or pitch deviation of the film material during processing. At this time, if the end of the zipper is not sufficiently crushed, a gap may be formed in the zipper depending on how the resin spreads when crushed, and this may become a leakage path and impair the sealing performance of the pouch. In particular, when the content contains liquid, leakage from the gap tends to be a problem.

Therefore, as shown in Patent Documents 1 to 3, it has been proposed to secure the sealing performance by applying a point seal. In Patent Document 1, as shown in FIG. 8, a point seal portion 21 is set prior to thermal welding of the side seal (vertical seal portion) 4 at the intersection between the zipper 8 and the side seal 4. . The width d ₁ of the point seal portion 21 is set wider than the width d ₀ of the side seal 4.

  In Patent Document 2, as shown in FIG. 9, the seal surface of one seal bar 22a used for heat sealing is formed flat, and the concave portion 22d is formed on the seal surface 22c of the other seal bar 22b. A rib 23 for strong fusion is formed in the concave portion 22d, and a strong fusion portion and a weak fusion portion are alternately provided at the end of a zipper (chuck tape) 8 that is thermally fused together with the sealing material 2. Yes.

  In Patent Document 3, as shown in FIG. 10, a spot seal portion 24 sealed with a spot sealer is formed at a location where the zipper (string chuck) 8 and the side seal 4 intersect in a T-shape, and immediately thereafter, the side seal bar The side seal 4 is applied and the ultrasonic seal 25 is applied over substantially the entire width of the zipper 8.

  However, in Patent Document 1, since the thickness is different between the side seal 4 portion applied to the end portion of the zipper 8 and the other side seal 4 portion, the side seal 4 is caused by a step between them. Defects are likely to occur. In this case, the above-described gap is generated, the sealing performance is impaired, and the contents may leak from there.

  In Patent Document 2, all of the side seals in the side seal 4 and the crushing of the end of the zipper 8 are performed at a time by the seal bar 22b. The seal bar 22b has a wide seal surface 22c, and the rib 23 hits the thickness of the zipper 8 because of the structure, so that the side seal 4 may be defective. Moreover, there exists a possibility of the leak by not being able to fully interrupt | block the space | gap which arises in the level | step difference in the case of the zipper 8. Furthermore, since the fitting parts (8a, 8b) of the zipper 8 are not directly pressed and crushed, the contents may leak from the fitting parts.

  Furthermore, in Patent Document 3, there is disclosed a method of preventing leakage from the fitting portion by applying an ultrasonic seal 25 to the end portion of the zipper 8 to melt the fitting portion of the zipper 8. However, since the ultrasonic seal 25 in this method stays in the range of the fitting portion of the zipper 8, heat and pressure are not transmitted to the step between the flange 8 c of the zipper 8 and the film material 2. The gap generated in the step remains, and there is a risk that a sealing failure will occur as well.

  The present invention has been made in order to solve the above-described problems of the prior art, and a problem to be solved is to ensure the sealing at the time of the zipper in the pouch with a zipper and to ensure the sealing performance.

  The pouch with a zipper according to the present invention has a resin film material in a bag shape that can contain contents by a peripheral seal portion, and is resealed after opening by a resin zipper that can be fitted to each other and sealed to the film material. The peripheral seal part formed over the area | region which crushed the edge part of the said zipper, and the spot seal part formed in the said area | region are provided. And the thickness of this spot seal part is equal to the thickness of the peripheral seal part except the said area | region, It is characterized by being thin.

  One aspect of the method for manufacturing a pouch with zipper according to the present invention is a method for manufacturing the pouch, a zipper sealing step for sealing the zipper to a film material, and a crushing sealing step for crushing an end of the zipper A peripheral seal step of forming a peripheral seal portion over a region where the end of the zipper is crushed, and a spot seal step of forming a partial spot seal portion in the region, the spot seal In the process, the thickness of the spot seal portion is equal to or thinner than the thickness of the peripheral seal portion excluding the region.

  Another aspect of the method for manufacturing a pouch with zipper according to the present invention is a method for manufacturing the pouch, wherein a zipper sealing step for sealing the zipper to a film material is performed, and an end of the zipper is crushed and applied to the film material. A peripheral seal step for forming a peripheral seal portion, and a spot seal step for forming a partial spot seal portion in a region where the end portion of the zipper is crushed, and in the spot seal step, the meat of the spot seal portion The thickness is equal to or thinner than the thickness of the peripheral seal portion excluding the region.

  Hereinafter, a zippered pouch according to an embodiment of the present invention will be described. Although the present invention is intended for all zippered pouches that contain contents, in this embodiment, liquid foods or the like that are administered to a viewer via a catheter or the like in a medical institution such as a hospital where sealing is particularly required. A zipper pouch having a spout in which an enteral nutrient or the like is accommodated will be described as an example.

≪Configuration of pouch with zipper≫
The configuration of the pouch will be described with reference to FIG. The pouch 1 has a resin zipper 8 sandwiched between two resin film materials 2 and is attached by heat sealing while intermittently feeding it out, and the peripheral portions of the film materials 2 are heat sealed to form a bag shape. After that, it is cut and manufactured, and the contents can be accommodated on the inner peripheral side of the peripheral seal portion.

  Specifically, the pouch 1 includes a top seal portion 3 formed in the left-right direction (arrow AB direction) of the upper edge of the film material 2 and the vertical direction (arrow CD direction) of both side ends. The formed side seal portion 4, the zipper 8 sealed to the inner surfaces of the both film materials 2, the throttle seal portion 9 formed on one side of both 3 and 8, the throttle seal portion 9 and the throttle seal portion 9 A spot seal portion 11 formed on the opposite side seal upper portion 4a, a spout 7 attached by a corner seal portion 6, and a bottom seal portion 5 formed at the lower end edge after filling the contents Yes.

  In such a pouch 1, an accommodation space for accommodating contents is formed by a peripheral seal portion mainly including the seal portions 3 to 6 and 9, and the cattle is connected to a spout 7, so that the patient can receive the contents. Is possible. The film material 2 is not particularly limited as long as it is made of a resin that can be welded to each other by heat sealing to form a pouch. For example, it may be a single layer of polyolefin resin such as polypropylene and polyethylene, but if necessary, a multilayer film structure in which a gas barrier layer, a heat seal layer, etc. are laminated after forming a resin film material capable of welding the innermost layer. It can also be. Alternatively, two film materials may be used to form a bag, or one film material may be folded vertically or horizontally to seal a peripheral edge to form a bag.

  The zipper 8 is disposed on the accommodation space side of the top seal portion 3, and as shown in FIG. 2A, a female portion 8a is formed on one facing surface of the zipper flange 8c, and a female member is formed on the other facing surface. A male portion 8b that can be fitted to 8a is formed. Here, in the flange 8c, the opposite surface (back surface) of the opposing surfaces of the two portions 8a and 8b is sealed by the film material 2 on the top seal portion 3 side of the both portions 8a and 8b. The accommodating space side of 8a, 8b is a blocking portion 8d that is bent.

  The blocking portion 8d is formed thin so that it can be broken manually by opening the zipper 8, and the top seal portion 3 is cut out along the easy opening mechanism 12 from the opening notch 13 between the two and the eight. After opening, resealing by both the parts 8a and 8b is possible, and contamination with germs and dust after opening is prevented. The material of the zipper 8 is not particularly limited as long as it is made of resin, and may be formed by extrusion molding a polyolefin resin such as polypropylene or polyethylene into a predetermined shape.

  A finger hooking hole 10 a is drilled at a position near the zipper 8 of the diaphragm seal portion 9. Thereby, for example, an index finger is inserted into the finger hooking hole 10a, and a thumb is put on the notch 4b of the side seal upper part 4a, and the opening of the opening is achieved by pressing both ends of the zipper 8 while holding the pouch 1 with one hand. Can be maintained. A hanging hole 10b is formed in the corner portion of the diaphragm seal portion 9 so that the pouch 1 can be suspended from a stand or the like placed near the patient's bed.

  The spot seal portion 11 is partially (spotted) formed in a region R where the end of the zipper 8 is crushed and sealed in the manufacturing process. That is, the zipper 8 is cut to a predetermined length, but both end portions thereof overlap the throttle seal portion 9 and the side seal upper portion 4a. Therefore, both ends of the zipper 8 are crushed, and the squeezed left and right regions R are formed with the throttle seal portion 9 and the side seal upper portion 4a (note that the side seal upper portion 4a is used during the sealing process of the throttle seal portion 9). The seal is also given.).

  One area R crushed here is located between the zipper 8 and the finger hooking hole 10a in the throttle seal 9, and the other area R is the width direction of the side seal upper part 4a, that is, the zipper 8 and the above-mentioned area. It is located between the notches 4b and tends to be thicker than the portions of the seals 4 and 9 where the crushing seal is not applied.

  Specifically, the spot seal portion 11 is formed in a vertically long shape, and cuts the region R along the direction of the arrow CD, and its upper and lower portions are formed over a range exceeding the vertical width in the same direction of the region R. ing. In addition, the spot seal portion 11 is disposed so as to cut substantially along the center of the lateral width of each region R within the range of the seal portions 4a and 9. As described above, when the spot seal 11 is performed while aiming at approximately the center of the width of the region R, even if the position of the spot seal is slightly shifted due to a pitch shift or the like when the film material 2 is fed out, This is preferable because the spot seal 11 can be reliably performed in the R.

  At this time, the thickness of the spot seal portion 11 is 75 to 100%, more preferably 85 to 95% with respect to the thickness of each of the seal portions 4a and 9 and the side seal portion 4 excluding the region R. Is formed. If this thickness is less than 75%, a problem in appearance occurs, and if it exceeds 100%, a problem of occurrence of a leakage path occurs. Further, in order to keep the appearance of the pouch in good appearance while suppressing the occurrence of the leakage path for the contents, it is preferable to form the spot seal portion with a thickness of 85 to 95%. In this manner, the spot seal portion 11 is formed in a thickness or thin shape equivalent to each of the seal portions 4a and 9 that is not subjected to the crushing seal despite being formed in the region R. A strong seal is given in point.

≪Manufacturing method of pouch with zipper≫
Hereinafter, a method for manufacturing the pouch 1 will be described. Here, the manufacturing method of the pouch 1 is the same as the sealing process of the zipper 8 in FIGS. 2B and 3 (hereinafter, zipper sealing process: S01) and the crushing sealing process (hereinafter, crushing sealing process: S02). The process of forming the aperture seal portion 9 (hereinafter referred to as aperture seal step: S03) and the step of forming the spot seal portion 11 (hereinafter referred to as spot seal step: S04) will be mainly described.

(1) Outline of Manufacturing Method First, an example of a manufacturing method of the zippered pouch 1 shown in FIG. 1 will be described based on FIG. 1 and FIG.
FIG. 2B shows a plurality of zippered pouches 1 manufactured continuously from above, and the two film materials 2a and 2b are in an overlapped state. The film materials 2a and 2b drawn out from a roll (not shown) and intermittently fed in the direction of the arrow L are intermittently fed in synchronism with the film material, and the zipper 8 cut at a predetermined length is interposed between them. The zipper sealing step (S01) is completed through a temporary welding device (not shown) of the zipper 8 and a zipper heat sealing device and a zipper cooling device which are fixed by the main welding.

  Thereafter, cooling is performed through a heat seal device (not shown) that sequentially executes the step of applying the top seal portion 3 (top seal step), the sealing steps (S02 to S04), and the step of applying the side seal portion 4 (side seal step). It is sent to the device and each seal is cooled and fixed. These heat seal devices are provided with heat seal bars prepared for each of the sealing process (S01 to S04), the top sealing process, and the side sealing process. The heat sealing bar has a built-in heater, and is a servo motor. Pressurization is possible by the operation of. The cooling of the cooling device may be air cooling by blowing air or water cooling using a refrigerant.

  After finishing each of these sealing steps and cooling into a bag shape, the easy opening mechanism 12 shown in FIG. 1 is laser processed to perform various cutting processes such as the finger hook hole 10a, the hanging hole 10, and the notch 4b, The side cut 15 is performed and it cuts for every bag. Then, a cutting process such as a corner cut at a position where the opening notch 13 and the corner seal 6 are applied is performed, the corner seal portion 6 is applied, and the spout 7 is attached, so that a finished product before filling the contents is obtained. At this stage, since the bottom seal portion 5 is not applied, the contents are filled from the lower end processed portion. After this filling, the bottom seal portion 5 is applied to obtain a final product, which is provided to consumers.

(2) Contents of Each Sealing Step (S01 to S04) Next, the sealing step (S01 to S04) will be described based on FIG. 2 (b) and FIG.

  S01: The zipper 8 cut by a zipper cutter (not shown) is sandwiched between two film materials 2a and 2b, and is sent to a temporary welding device (not shown) for temporarily welding the zipper 8. The temporary welding part 14 is point-sealed by the temporary welding apparatus, and the zipper 8 is temporarily welded to the film materials 2a and 2b.

  This temporary welding portion 14 is in the region H of the zipper 8 on the top seal 3 side, and it is preferable to point-seal the upper side in the traveling direction of the film materials 2a and 2b. In addition, as temporary welding, it is suitable to complete welding for a short time using an ultrasonic welding apparatus etc. After point-sealing the temporary welded portion 14 of the zipper 8, the film materials 2a and 2b are sent to the heat seal device to weld the region H on the top seal 3 side of the zipper 8, and then sent to the cooling device to The region H is cooled to fix the welding, and the zipper sealing process is completed. In addition, the manufacturing apparatus and method described in patent document 4 were used for the temporary welding of these zipper 8 and a zipper sealing process (S01).

  S02: Film material 2a, 2b on which the zipper 8 is welded in the zipper sealing step (S01) is sent to the heat seal device, and after applying the top seal 3, a crushing sealing step for applying a crushing seal R to the end of the zipper 8 (S02) is performed. Specifically, a pressing step is performed in which the servo motor is operated to heat and press the entire end portion of the zipper 8 with a seal bar for crushing sealing, and the entire end portion is crushed. The region R is formed by the resin flow during the pressing step. It is also suitable to repeat the crushing seal pressing step one or more times. This repeated pressing step may be a step of pressurizing the entire end portion of the zipper 8 in the same manner as the pressing step, or it is limited to a range in which the end portion of the zipper 8 is heated and melted without pressing, and in the pressing step, It is good also as a front | former stage process for making it easy to crush the whole edge part.

  S03: After the crushing and sealing step (S02), the drawing and sealing step is performed on the region J in FIG. That is, the film materials 2a and 2b that have been subjected to the crushing sealing step (S02) are sent out in the direction of the arrow L, and a region J that includes the front and rear regions R using a sealing bar for a crushing diaphragm seal heated by a built-in heater. Is pressurized. As a result, as shown in FIG. 2B, the throttle seal portion 9 is formed in the region J on the rear side in the traveling direction, and at the same time, the side seal upper portion 4a is formed in the region J on the front side in the traveling direction.

  S04: After the aperture seal process (S03), the area R is subjected to a spot seal process using the heat seal bar 26 shown in FIG. Here, the heat seal bar 26 is arranged orthogonal to the feeding direction (the arrow L direction) of the film materials 2a and 2b in FIG.

  Therefore, if the region R is pressurized with the heat seal bar 26 heated by the built-in heater, the spot seal portion is formed in the vertical direction of the arrow L, that is, in the longitudinal direction of the region R (the direction of the arrow CD in FIG. 1). 11 is formed. At this time, since the pressing surface 26a of the heat seal bar 26 is formed in an arc shape as shown in FIG. 4, the region R is not damaged at the time of pressurization, and cracks in the region R are prevented in this respect. ing. The lateral width M of the seal bar 26 is defined according to the length of the arcuate radius (r) of the pressing surface 26a.

  Here, when the position of the crushing seal bar is shifted due to the meandering or pitch shift of the film materials 2a and 2b, the pouch 1 becomes insufficient and the crushing seal becomes insufficient. May occur. Therefore, the pouch 1 forms the spot seal portion 11 in the region R in the spot seal step (S04), thereby closing the gap at the time of the zipper 8 and preventing the leakage path of the contents from occurring. This point will be described in detail with reference to FIG.

  FIG. 5A shows an enlarged view (comparative example) of the side seal upper portion 4a of the pouch with zipper in which the spot seal step (S04) is omitted, and P indicates a gap generated at the time of the zipper 8. FIG. Here, since the gap P penetrates the side seal upper portion 4a, it is a leakage path for the contents.

  FIG. 5B shows an enlarged view of the side seal upper portion 4 a of the pouch 1, and a spot seal portion 11 is formed in the region R. Since the thickness of the spot seal portion 11 is equal to or thinner than that of the seal portions 4a, 9 and the side seal 4, a strong seal is provided here.

  Accordingly, the gap P in FIG. 5A is blocked by the spot seal portion 11, and the occurrence of the leakage path for the contents is prevented. In particular, since the spot seal portion 11 cuts through the region R, it is possible to reliably close a leakage path that attempts to communicate from the zipper 8 toward the outside. In this respect, the zipper edge is reliably sealed, and its sealing performance Is secured.

  Further, the pressing surface 26a of the heat seal bar 26 has a horizontal width M of the seal bar 26 defined according to the length of the radius (r). It is possible. The length of the radius (r) is preferably 1 to 4 mm, and accordingly, the lateral width M is preferably 2 to 8 mm.

  Further, in the spot sealing process, as shown in FIG. 4, a rubber 16 made of silicon or the like is laid under the pouch 1 and pressed by the heat seal bar 26 to form the recesses 17a and 17b, resulting in a stronger seal. For this reason, the spot seal portion 11 is formed to a thickness of 100% or less with respect to the thickness of each of the seal portions 4 a and 9 and the side seal portion 4 except for the region R.

  In the present embodiment, the heat sealing bar and the rubber are used for the sealing in the spot sealing process. However, the same effect can be obtained by using a pair of heat sealing bars or metal plates in which the rubber on the lower surface is the heat sealing bar. . Further, the position of the heat seal bar and rubber, or the heat seal bar or the metal plate may be turned upside down, and the spot seal portion may be formed on the back surface of the film material.

≪Other / Other examples≫
The present invention is not limited to the above-described embodiment, and can be implemented by being modified within the scope described in each claim. For example, although the case where two film materials are used is described as an example in the present embodiment, a single film material may be folded vertically or horizontally and the periphery may be sealed to form a bag shape.

  Further, the spot seal portion 11 does not necessarily have to be formed by cutting the entire region R vertically, and as shown in FIG. 6A, at least the content storage side in the region R (the arrow in FIG. 1). It suffices if the portion 18 is vertically cut during the crushing on the D side. Further, as shown in FIG. 6B, the crushing portion 18 may be vertically cut from a position 19 corresponding to the fitting portion (8a, 8b) of the zipper 8 in the region R.

  That is, even if a gap is generated from the position 19 corresponding to the fitting part (8a, 8b) of the zipper 8 in the region R to the top seal 3 side (arrow C side in FIG. 1), the both parts 8a, 8b Since the contents can be prevented from leaking by fitting, no problem occurs. In these cases, the spot seal step (S04) may be performed by adjusting the length of the heat seal bar 26 in the longitudinal direction.

  Further, it is also preferable to execute the throttle sealing step (S03) again after the spot sealing step (S04) in FIG. 2B and then execute the cooling step. According to this processing step, the recesses (see FIG. 4B) of the spot seal portions 11 formed on both surfaces of the film material 2 and the protrusions around the spots can be flattened, and the appearance can be improved. . Also, in the sealing process in FIG. 2B, even when the order is changed so that the spot sealing process (S04) is performed next to the crushing sealing process (S02) and then the throttle sealing process (S03) is performed. Similarly to the above, the spot seal portion 11 and its periphery can be flattened, and the appearance can be improved.

  Furthermore, even in the case of a general zipper with a zipper that is produced by continuously feeding out the zipper 8 without the finger hole 10a, the suspension hole 10 or the like in the shape of the zipper pouch 1 shown in FIG. Since the end part of the side seal part 4 and the zipper 8 overlaps, the present invention can be implemented. An example of a method for producing the zipper 8 by continuously feeding it out is shown in FIG.

  In FIG. 7, the side seal process (S03-2) which also serves as the crushing (S02-2) of the end of the zipper 8 is performed instead of the aperture seal process (S03), and then the spot seal process (S04), The method of performing a crushing sealing process (S02) is shown. In this side seal step (S03-2), only the side seal upper part 4a (not shown) may be crushed at a position corresponding to the side seal upper part 4a of FIG.

  In particular, some pouch and zipper materials have a low melting point. In such a material, the crushing sealing step (S02) is omitted as shown in FIG. 7, and the zipper sealing step (S01), side seal is omitted. Sealing can also be performed in the order of the step (S03-02) and the spot sealing step (S04). In this case, since the end of the zipper 8 is crushed during the side sealing step (S03-02) (S02-2), the sealing step can be simplified and the manufacturing process time can be shortened.

  If the side sealing step (S03-02) is performed again after all the sealing steps as described above, the spot seal portion 11 and its periphery can be flattened and the appearance can be improved.
