Description

  The present invention is a series of liquid packaging bags filled and packed with fluid substances such as liquid and jelly-like foods and drinks, seasonings and other various liquid or viscous foods and drinks, pharmaceuticals and cosmetics. It relates to a continuous packaging bag. In particular, the present invention proposes a continuous packaging bag that can prevent erroneous opening of the packaging bag when the continuous packaging bag is cut into each packaging bag through a tear line.

  Patent Document 1 discloses a liquid packaging bag that is easy to open, has a good unsealed state, and can prevent dripping or splashing when a packaged article is poured out.

  In the liquid packaging bag of Patent Document 1, a laminated film including at least a base film layer and a sealant layer is folded back in the width direction so that the sealant layers face each other, and then side edges are vertically heat-sealed. In addition, the upper end and the lower end are laterally sealed, and the upper horizontal seal portion is not subjected to vertical heat sealing, and the narrow side that communicates with the package storage space on one folded side portion And an arcuate or linear tearing guide rod is formed from the upper end side of the upper lateral seal portion toward one side portion of the extraction passage.

  According to this liquid packaging bag, since the pouring passage of the packaged object is provided on the base end side of the laminated film that is not heat-sealed, the spout portion does not need to apply pressure, The laminated film is always opened in a straw shape (elliptical shape) due to the restoring force of the laminated film, the amount of the package to be poured can be controlled by pressing the storage space, and the pouring path gradually narrows toward the pouring port. Due to the width, the packaged item is poured out in a certain direction along the dispensing passage, so that the packaged item does not scatter during the dispensing, and the packaged product is well drawn. In addition, there is no risk of dripping during pouring.

Further, in this liquid packaging bag, the tear guide rod of the liquid packaging bag is provided on the upper lateral seal of the packaging bag, the start end thereof is formed apart from the spout portion, and the tear guide rod is separated from the start end and the upper lateral side of the tear bag. Since the clearance of 0.3 to 1.0 mm is provided on the upper end side of the seal, it is possible to obtain an effect that the packaged bag does not break and the packaged article does not leak unexpectedly during handling of the packaging bag.
Japanese Patent Application No. 2006-257565

  However, when a large number of liquid packaging bags described in Patent Document 1 are continuously connected via a separation line made of perforated holes and melting marks to form a continuous packaging bag, even if the leading edge and the upper side Even if a clearance of 0.3 to 1.0 mm is provided on the upper end side of the seal, the tearing guide rods are pulled and pulled when the continuous packaging bag is separated into the respective packaging bags along the separation line. Could be opened.

  The present invention aims to solve the above-mentioned problems, and effectively prevents breakage of the tearing guide bag when the continuous packaging bag is separated into each packaging bag through a separation line composed of perforations or the like. Provide a continuous packaging bag that can.

  As a result of intensive studies to achieve the above object, the present invention has developed the method described below. That is, according to the present invention, a laminated film including at least a base film layer and a sealant layer is folded in the width direction so that the sealant layers face each other, and then the side edges are vertically heat-sealed to vertically Forms a seal part and forms a horizontal seal part that provides a space for storing packages by heat-sealing the upper and lower ends in the width direction, and forms a vertical seal part of the upper horizontal seal part An extraction passage which is communicated with the packaged article storage space and gradually narrows in the protruding direction is provided on the folded-back side portion positioned on the unwrapped side, and the extraction passage extends from the upper end side of the upper lateral seal portion. For the packaging bag provided with an arc-shaped or linear tear-inducing ridge toward one side of the side, the separation line formed on the upper side of the upper side horizontal seal part and the lower side of the lower side horizontal seal part Via more than one A continuous packaging bag in which a bag is connected, wherein the separation line can be separated by a separation resistance smaller than a tear resistance of the tear guide line. suggest.

In the continuous packaging bag of the present invention, the size of the wrinkle or melt mark constituting the tear line is a line smaller than the size of the wrinkle or melt mark forming the tear guide line, the cut line Is a line in which the separation resistance of the portion overlapping with the formation range of the tear guide rod is smaller than the separation resistance of the other portion, and the pouring passage is a three-side seal bag, a central joint seal bag, Provided on the width direction side portion of the sealing bag, the pouring passage forms a conical passage gradually tapering toward the upper end of the upper lateral seal portion, and tearing along the tear guide rod extending in the arc shape The liquid outlet port of the outlet passage opened by is formed by being torn after being bent parallel to or upwardly with the upper edge of the lateral seal portion of the packaging bag, The width of the outlet in the width direction is approximately 0.3 to 50 mm, the clearance between the end of the tear guide rod and one side of the extraction passage is 0.3 to 5.0 mm, the tear guide rod The clearance between the start end of the upper side seal portion and the upper end of the upper side seal portion is 0.3 to 1.0 mm. Provided with at least a pair of protrusions projecting to the upper end, provided with a pair of knurled seal portions at the upper end of the upper lateral seal portion, spaced apart from the tear guide rod, the base film layer and the sealant between the layers, SiO ₂ deposited layer, vinylidene coating layer chloride, aluminum oxide coating layer, Al deposited layer or SiO ₂ or Al, to provide an intermediate layer made of the sputtering layer, such as Al ₂ O _3, the Besufi The film layer is made of a resin film such as an ethylene vinyl alcohol copolymer, polyolefin, polyester, polyamide, polyimide or vinylidene chloride, the sealant layer is made of a polyethylene layer or a polypropylene layer, at least below the liquid spout It is preferable that a water repellent layer is provided on the outer surface of the side portion located on the side, and that the water repellent layer is made of a silicone-based, fluororesin-based, acrylic-based or amide-based coating agent.

According to the continuous packaging bag having the above-described summary configuration, the tear resistance of the tear line connecting the liquid packaging bags is smaller than the tear resistance of the tear guide rod, so the tear line is more than the tear guide rod. Therefore, when the continuous packaging bag is pulled along the separation line and separated into the respective packaging bags, the separation line is torn preferentially, and the tearing guide rods may be linked and opened. There is no. Note that the tear resistance can be adjusted by changing the size of the flaws or melt marks constituting the tear line and the tear-inducing flaw.
Further, by reducing only the tearing resistance force of the part that overlaps the formation range of the tearing guide rod, that is, the portion corresponding to the range from the starting end to the terminal end of the tearing guide rod, the other parting line As a result, the tensile strength is maintained, and there is no possibility of the tear line being accidentally broken during bag making operations or during handling such as movement, packing, and transportation.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a schematic sectional view showing an example of a laminated film forming a liquid packaging bag constituting the continuous packaging bag according to the present invention. The laminated film 1 includes a base film layer 2 and a sealant layer 3, and an intermediate layer 4 may be provided between the base film layer 2 and the sealant layer 3 as necessary. The laminated film 1 is formed by laminating the base film layer 2, the sealant layer 3 and the intermediate layer 4 by, for example, extrusion lamination or dry lamination.

  The base film layer 2 is preferably composed of a synthetic resin film such as a uniaxial or biaxially stretched ethylene vinyl alcohol copolymer, polyolefin, polyester, polyamide, polyimide, or vinylidene chloride. Permeability and high gas barrier properties can be exhibited.

In particular, the biaxially stretched polyethylene terephthalate film layer uses “Emblet PC” (trademark Unitika Co., Ltd.), which is a straight-cut polyester film. It is preferable to use “Emblem NC” (trademark Unitika Ltd.), which is a conductive nylon film, for the following reasons.
That is, according to these, in addition to imparting higher water vapor impermeability, gas barrier properties, etc. compared to the case of using a uniaxially stretched base film layer, linear tear removal by fingers of the tear opening part Can be made smooth and easy, and the teared wrinkles can be made sufficiently smooth without fluffing.

  Moreover, if a polyethylene layer or a polypropylene layer is used as the sealant layer 3, an excellent sealing strength can be exhibited at a relatively low heat sealing temperature.

In addition, the intermediate layer 4 is preferably laminated as appropriate in order to improve the properties required for the packaging bag, such as water vapor impermeability, gas barrier properties, stiffness, etc., SiO ₂ vapor deposition layer, vinylidene chloride coating layer, An aluminum oxide coating layer, an Al vapor deposition layer, or a sputtering layer such as SiO ₂ , Al, or Al ₂ O ₃ is suitable.

  The laminated film 1 having the above structure is folded in the width direction so that the sealant layers 3 face each other, and then each side portion excluding the base end is sealed in three directions to obtain a liquid as shown in FIG. A packaging bag 5 is formed. In addition, the part which gave the oblique line in a figure shows the heat seal part of a packaging bag. The upper lateral seal portion 6 is formed with a triangular non-sealed portion at the lower side end on the packaging bag base end side 7 side, and this non-sealed portion is used as a liquid discharge passage 8 to store packaging objects. 12 communicates. Further, before or after the formation of the lower lateral seal portion 9, a tear guide rod 10 is formed from the upper end of the upper horizontal seal portion 6 as a starting end toward the dispensing passage 8, and the tear guide rod 10 is used as a boundary to the upper side. The horizontal seal portion 6 is grasped with both fingers, and the liquid spout 11 is formed by easily tearing and opening the tear seal along the tear guide rod 10 using the leverage of fingers. In FIG. 3, the tear guide rod 10 is curved, but a straight shape as shown in FIG. 3B may be used, or a plurality of curved and linear tear guide rods 10 are combined. May be formed.

  As shown in FIG. 4, the continuous packaging bag 30 of the present invention is formed by connecting a plurality of liquid packaging bags 5 via separation lines 31 made of perforations or melting marks such as perforations, and the separation lines. The depth, length, and the like of the ridges forming the 31 are made smaller than the size of the ridges forming the tear induction rod 10, and the tear resistance of the tear line 31 is set to the tear resistance of the tear induction rod 10. It is characterized by being smaller than force. By configuring the separation line 31 in this way, the separation line 31 is easier to cut than the tear induction bag 10, and when the continuous packaging bag 30 is pulled and separated into the liquid packaging bags 5, the separation line 31 is separated from the tear induction bag 10. The line 31 is torn preferentially, and there is no possibility that the tearing guide rod 10 will be opened by mistake.

  In addition, in the continuous packaging bag 30 of the present invention, as shown in FIG. 5, the size of the rivet or the like in the range 31 a from the start end to the end of the tearing guide lashes 10 in the separation line 31 is set to other portions. It is preferable to make it smaller than the separation lines 31b and 31c. With this configuration, the separation line 31a is torn with a large force for tearing the separation line 31b or 31c, and the separation line 31a is further easily separated, and continuous packaging is performed by the separation lines 31b and 31c. The tensile strength of the bag 30 will be maintained, and the separation line 31 will not be broken during bag making operations or during handling such as movement, packing, and transportation.

  The separating line 31 and the tearing guide rod 10 are a single rod provided extending in the-(minus) shape in the width direction of the laminated film, a plurality of punches perforated in the width direction, and the width direction thereof. It is formed by a plurality of small holes having a suitable shape and number, such as a plurality of small hole holes provided at intervals, or melt marks provided continuously or intermittently with a laser beam or the like.

  Further, the liquid packaging bag 5 constituting the continuous packaging bag 30 of the present invention is heat-sealed such as a three-sided seal type packaging bag in FIG. The present invention can be applied to a packaging bag having a folded side that is not made.

  Moreover, the liquid extraction channel | path 8 is not limited to a triangular shape, It is preferable that it is a shape which becomes narrow gradually toward the liquid extraction port 11 formed by the method mentioned later. This is because the pouring path 8 tapers toward the liquid pouring port 11 so that the extrusion direction of the packaged article becomes constant, the packaged article does not scatter and the occurrence of dripping is suppressed. It can be done. In addition, this liquid pouring channel | path 8 can be formed by using the bottle-shaped heat seal blade which consists of a shape where the base end side 7 side end was recessed in triangle shape. In addition, as the shape of the heat seal, a solid seal, a three-wire seal, a fabric seal, or the like can be used, and in particular, a solid seal or a three-wire seal is preferably used from the viewpoint of sealing reliability and safety.

  In addition, although the spout 11 is provided in the base end side 7 side of the packaging bag 5 as for the liquid packaging bag 5, the base end side 7 side of the packaging bag 5 does not apply pressure, but the laminated film 1 Because of the force to restore the state before folding, it is always opened in a straw shape (elliptical shape), and the pouring passage 8 is gradually narrower toward the pouring port. The object can be smoothly poured out in a certain direction along the dispensing passage 8 by the pressing of the storage space 12, so that the packaged material is scattered at the time of liquid dispensing as in the prior art. Does not stain clothing.

  Further, the liquid packaging bag 5 does not leak from the dispensing passage 8 even when the packaged bag is tilted due to the action of the surface tension of the liquid packaging bag 5. Can be adjusted by.

  Further, since the packaged object is not poured out beyond the vertical seal portion but directly from the spout tip 11a, there is no occurrence of liquid dripping due to the packaged material traveling along the vertical seal portion.

  Furthermore, the liquid packaging bag 5 is moved, packed and transported by providing a clearance of 0.3 to 1.0 mm between the starting end 10a of the tear guide bag and the upper end side 6a of the upper lateral seal portion 6. During handling, especially when separating continuous packaging bags one by one through the perforation or every several required bags, it is possible to prevent the guide rod 10 from unexpectedly breaking and leaking the packaged items. it can. When the clearance is smaller than 0.3 mm, the above-mentioned effect cannot be expected. On the other hand, when the clearance is larger than 1.0 mm, the packaging bag 5 cannot be cut off at the tearing guide starting end 10a and can be opened with fingers. Can not.

  Furthermore, since the starting end of the tear guide rod 10 is located in the middle of the upper end of the upper side seal portion 6 at 10a, the start end 10a of the tear guide rod 10 is caught by a roll or the like during automatic filling packaging, and the guide rod 10 is The guide rod 10 does not break, and is less likely to bend than a conventional guide rod formed in a straight line from the vertical seal portion, and does not break during movement.

  Moreover, it is preferable that the dimension in the width direction of the liquid spout 11 formed by tearing by the tear guide rod 10 is in the range of 0.3 to 50 mm, and this dimension depends on the type of the package, the viscosity, and the like. Determine as appropriate. The “substantially width direction” herein refers to a case in which the tear guide ridge formed on the packaging bag in the present invention is formed to be inclined upward. The reason why the spout 11 is limited to 0.3 to 50 mm is that if it is smaller than 0.3 mm, the amount of the pour is too small. This is because a force greater than the tension acts, and the packaged item leaks out from the spout 11 or the amount of pouring cannot be adjusted by controlling the finger pressure.

  Furthermore, it is preferable that the clearance between the end 10b of the tear guide rod and the liquid discharge passage 8 is 0.3 to 5.0 mm. This means that when the clearance is smaller than 0.3 mm, the packaging bag 5 moves, packs and transports. During handling, etc., the guide rod 10 may break unexpectedly by receiving its own drop impact or stacking load, etc., and the packaged material may leak out, while the clearance is larger than 5.0 mm In this case, the packaging bag 5 cannot be cut off at the tearing guide heel end 10b and cannot be opened with fingers.

  In particular, when the tear guide rod 10 is curved as shown in FIG. 3, the spout 11 opened by tearing and opening the tear guide rod 10 is horizontal to the width direction of the liquid packaging bag 5. (FIG. 6 (a)) Or, since it is provided so as to curve upward (FIG. 6 (b)), the spout 11 is curved horizontally or upward with respect to the width direction of the liquid packaging bag 5. When formed, the liquid to be packed is well drawn, and particularly when it is curved upward (FIG. 5 (b)), the spout tip 11a becomes thin (sharp), so it is transferred to another container. The effect that it is difficult to spill in some cases can be expected.

  In addition, in the tear guide rod 10 having a curved shape, the portion having a radius of curvature of 10 mm or less has a tight curve. Therefore, the tear guide rod 10 may not be able to tear along the ridge formed as described above. Rather, it is preferable to set the entire cut state.

  Further, as shown in FIG. 7, the protrusion 13 (FIG. 7 (a)) or the knurled seal portion 14 (FIG. 7 (b)) is placed at a position spaced apart from the tear induction fistula starting end 10a of the liquid packaging bag 5. It is preferable to provide them as follows. The protruding portion 13 or the knurled seal portion 14 grips the packaging bag 5 with the tear guide rod 10 as a boundary, grips the upper side seal portion 6 with both fingers, and utilizes the leverage of the tear guide rod from the tear guide rod starting end 10a. In addition to the effect of preventing the fingers from slipping when tearing and tearing, it is possible to detect the tearing guide start edge 10a with a tactile sense, and even a visually impaired person can easily find the position. There is an effect that can be.

Therefore, the protrusion 13 or the knurled seal portion 14 needs to be provided in pairs on both sides of the upper side seal portion 6 at a position where it is gripped with both fingers, i.e., near the tear guide start end 10a. A plurality of pairs of protrusions 13 may be formed on both sides of the tear guide rod 10, and the size of each knurled seal portion 14 is at least a size that can be gripped with fingers, for example, 10 mm (the length of the upper side seal portion). (Span direction) × 5 mm (upper lateral seal portion width direction) is sufficient.

  The protrusion 13 can have various shapes such as a circle, a triangle, a quadrangle, and a polygon. The method of forming the protrusion 13 includes a pair of the above-described two pairs positioned on the surface of one heat seal blade of the horizontal heat seal roll for forming the upper horizontal seal portion 6 with an interval in the film width direction. The upper side seal portion 6 is formed on the packaging film that has passed between the two heat seal blades by providing a recess having a shape and each of the other heat seal blades corresponding to the recesses. By forming the protrusion 13 at the same time as the formation of. Similarly, the knurled seal portion 14 can also be formed without adding a special process by forming a knurled rough surface on each surface of the pair of transverse heat seal blades.

FIG. 8 is a plan view showing another embodiment of the liquid packaging bag 5 in a filled and packed form of an article to be packaged.
This packaging bag 5 has an upper side seal 6 as a wide seal portion, and is not subjected to heat sealing in a packed and packed state of an object to be packaged, one end portion in the extending direction of the base end side 7 of the packaging film, In the drawing, a liquid discharge passage 8 is defined at the upper end portion, and in the upper side seal 6 from the upper end side to the liquid discharge passage 8, in the drawing, in a curved shape that protrudes downward. The tear guide 10 is formed of a perforated hole extending in a curved line, and the maximum width of the liquid discharge passage 8 along the base end side 7 as shown in FIG. And a water repellent layer 27 of equal width.

Here, the formation of the water-repellent layer 27 can be made narrower as well as wider. By the way, such a packaging bag 5, for example, as shown in a partially developed plan view in FIG. 9, the laminated film 1 in which the water repellent layer 27 is formed in a band shape in the width central region is folded in half in the width direction, The film 1 can be manufactured by applying a continuous vertical seal to the free end portion of the film 1 and applying each horizontal seal while filling an article to be packaged.
By the way, such a water-repellent layer 27, for example, a water-repellent layer 27 that can be formed by application of a silicone-based, fluororesin-based, acrylic-based or amide-based coating agent, is provided for each individual packaging bag 5 or vertical seal. Of course, it can be formed on the packaging film after the portion is provided. However, when the formation efficiency of the water-repellent layer is taken into consideration, it is preferable to carry out the step before the lamination of the laminated film.

  In the case of forming the water repellent layer 27 at the stage of the laminated film 1, in order to increase the fixing strength of the water repellent layer 27 to the film surface, It is preferable to use a resin such as acrylic, ester, nitrified cotton, amide, vinyl chloride, rubber, styrene, olefin, vinyl chloride, cellulose, and phenol as the binder.

By the way, based on the tilting operation of the liquid packaging bag, when the packaging bag is tilted little by little while adjusting the amount to be poured at the beginning of the package, conventionally, it is below the formed spout of the packaging bag. In the liquid packaging bag according to the present invention, under the action of the water-repellent layer 27, the base end side 7 of the base end side 7 will flow down along the base end side 7 that will be located on the side. Since the wetting by the packaged item is sufficiently prevented, the packaged item flows down directly below the spout 11 due to high liquid drainage or water repellency, so that the unpackaged item is unintended. The fear of dripping is effectively removed.
Here, when the tilting amount of the liquid packaging bag 5 is such that the base end side 7 is positioned above the spout 11, it is not necessary to wait for the water repellent layer 27 to act, Therefore, it is possible to sufficiently prevent the flow down to an unintended location.

  The continuous packaging bag according to the present invention wraps soy sauce, sauces, various seasonings, soups, fruit juices, other liquid or viscous foods, detergents, pharmaceuticals, etc. It can be used as a continuous packaging bag.
