Definitions
- the present invention relates to a packaging container, and particularly relates to a packaging container that can be easily unsealed.
- tetrahedral packaging material in which the direction of one side is orthogonal to the direction of the opposite side is known as the so-called tetra-type packaging material (trade name: Tetra Pak).
- Patent Document 1 a food-grade packaging bag is described in which a circuitous part that protrudes upward to a perforated line for unsealing is provided, and can be easily opened by opening the circuitous part to the left and right.
- Patent Document 2 a structure is described in which an adhesive material is interposed between the lid and the trunk of the packaging bag assembly to facilitate unsealing.
- Patent Document 3 a tubular packaging material with a backing member having constant width tearing property is described in, e.g., Patent Document 3 as a packaging material that facilitates unsealing, and a packaging material having excellent tearing characteristics is described in Patent Document 4 in which a film having tearing characteristics is sandwiched and laminated by different tearing-type films.
- Patent Document 4 a packaging material having excellent tearing characteristics is described in Patent Document 4 in which a film having tearing characteristics is sandwiched and laminated by different tearing-type films.
- the packaging material known in the prior art described above is provided tearing characteristics by using a special configuration or structure in which a special shape is added to the perforation line in order to facilitate unsealing, adhesive material is interposed between the trunk and the lid of a packaging bag assembly, a backing member having constant width tearing property is provided, and tearing-type films are sandwiched and laminated by different films.
- a special configuration or structure in which a special shape is added to the perforation line in order to facilitate unsealing, adhesive material is interposed between the trunk and the lid of a packaging bag assembly, a backing member having constant width tearing property is provided, and tearing-type films are sandwiched and laminated by different films.
- the present invention was contrived in view of such conditions, and an object thereof is to provide a packaging container produced in a process in which a packaging object is accommodated and a necessary sealing section is used as an unsealing guide for tearing when a bag assembly with one open end is manufactured, whereby unsealing is facilitated without the adoption of special means.
- the present invention provides a packaging container having a tetrahedral shape formed by closing two sides of a pair facing each other and one side of the other two sides facing each other by using the first through third sealing sections, and provided with a fourth sealing section that is substantially orthogonal to the third sealing section in a state in which a packaging object is placed in a bag having the remaining one side open, whereby the opening is sealed, the packaging container being characterized in that the first and the second sealing sections are used as an unsealing guide for tearing of the packaging container.
- the first and second sealing sections provided with two facing sides are used as an unsealing guide for opening by tearing of the packaging container when a bag assembly that has one open side is formed, unsealing is facilitated without the adoption of special means.
- the first and second sealing sections can be composed of a heat-seal line.
- the packaging container has first and second triangular shapes in which the fourth sealing section is used as a shared bottom side, and third and fourth triangular shapes in which the third sealing section is used as a shared bottom side, and is formed in a tetrahedral shape in which the oblique sides of all the triangular shapes adjacent in the circumferential direction are connected; and the first and second sealing sections can be positioned on a perpendicular line of the first and second triangular shapes.
- the packaging container When unsealed via an unsealing guide for tearing, the packaging container can be formed in a boat shape in a state in which the packaging object is placed, and the spread-out boat shape functions as a vessel that holds the contents and functions as a graspable dish in the case that the contents are food items.
- the packaging container is positioned in the center section of the fourth sealing section, and is provided with an easy-open section composed of a notched section, a perforated line, a hole, or the like positioned on an extension of the unsealing guide section.
- the packaging container can be formed from a material that transmits a low level of UV rays.
- the packaging object may, in principle, be any object, and may be lettuce, spinach, or another vegetable.
- the packaging container may be provided with a plurality of chambers inside the packaging container that are partitioned by pockets or walls that are simultaneously unsealed when the packaging container is unsealed along the unsealing guide for tearing, and may be designed so that the contents of the plurality of the pockets or chambers appear when the packaging container is unsealed.
- the packaging container has air internally sealed together with the packaging object, and a corner-pull seal line can be provided to each corner section of the packaging container.
- the corner-pull seal line can be formed as a circular arc or straight line that connects between the first and second sealing sections and the third and fourth sealing sections.
- a packaging container of the present invention the opening of a packaging container is facilitated without adopting special means because a first and a second sealing section provided with two facing sides act as an unsealing guide for tearing the packaging container when the bag assembly with one side opened is formed.
- the packaging container functions not only as the packaging of the articles, but is also one in which a package material is spread out in the shape of boat and the boat shape produced by the spreading functions as a vessel for contents when the packaging container filled with contents is unsealed.
- the boat shape serves as a type of plate, and food items placed thereon can be eaten from this boat shape.
- the packaging container of the present invention functions merely not only as a package, but also additionally functions as a vessel for holding and grasping the contents. An application is also possible in which pockets and partitions are provided and the different contents are placed therein.
- FIGS. 1 through 5 show an embodiment of the packaging container according to the present invention.
- FIG. 1 shows a tetrahedral bag assembly 1.
- a side AB is open and the other sides are sealed. Ordinarily, the contents are added from the open section of A-B, and A-B is then sealed to form a packaging container.
- A-B is not immediately sealed, but rather the corners A and B are brought together, joined so that the direction of the side A-B and the direction of a side C-D are substantially orthogonal, and sealed in this state.
- This is widely known as a so-called tetra-type packaging material, and example thereof is Tetra Pak, which is a registered trade name.
- a side A-C is a first sealing section 2, a side B-D is the second sealing section 3, and these sealing sections 2, 3, are formed from a folding line, a heat-seal line, a perforated line, or the like.
- the side C-D is a third sealing section 4, and a portion sealed at an angle substantially orthogonal to the side C-D is a fourth sealing section 5.
- the present invention will be described with reference to a square-shaped packaging container, but the shape of the bag is not limited to a square shape and the shape can also be trapezoidal.
- the side A-C and the side B-D are, respectively, the first sealing section and the second sealing sections 2, 3 composed of a folding line, a heat-seal line, a perforated line, or the like in FIG. 1 .
- the corners A, B are the two end corner sections of the upper side.
- the seal lines of the first and second sealing sections 2, 3 are the unsealing guide as described below.
- a notched portion, perforated line, hole, or another easy-open section may be provided to the bonded and sealed portion in which the corners A, B are brought together, and a reinforcement section formed by hot fusion, by a reinforcement member, or the like can also be provided to the periphery of the corners C, D.
- the corner A and the corner B are brought together and joined to seal the open section so that the direction of the side A-B is substantially orthogonal to the direction of the side C-D.
- This sealing section acts as a fourth sealing section 5.
- H-H' (facing side), which is the center point of the side A-B, forms a corner
- the original corner A and the original corner B are the center point of the side H-H' in a state in which the corners A and B have been brought together and sealed so that the side A-B is orthogonal to the direction of the side C-D.
- J is a focus point underneath the band 13
- J' is a focus point underneath the band 13 of the facing side.
- a first triangle (GG'C) and a second triangle (GG'D) are formed as a pair in which the side G-G' that is the fourth sealing section 5 serves as the shared bottom side; and a third triangle (CDG) and a fourth triangle (CDG') are formed as a pair in which the side C-D that is the third sealing section 4 serves as a shared bottom side to produce a tetrahedral packaging container in which the diagonals of the triangular shapes adjacent in the peripheral direction are connected to each other.
- a diagram of a tetrahedral packaging container 6 is shown in FIG. 3 .
- FIG. 2(a) is a view as seen from the original plane ABDC and FIG. 2(b) is a view as seen from an angle rotated 90 degrees from the surface of the original ABCD. Since the packaging container 6 is formed as a tetrahedral structure, there is resistance to external pressure and the contents can be clearly viewed when a transparent material is used as the material that forms the bag assembly 1. Nitrogen or carbon gas is sealed in the packaging container 6 as necessary, and the degradation of freshness of the contents can be prevented.
- a resin film or resin sheet can be used as the material for the bag assembly 1.
- a resin that may be used include polyethylene, polypropylene, and other polyolefins; and polyester, polyamide, polycarbonate, polystyrene, polyvinyl chloride, polyvinylidene chloride, a copolymer of ethylene and vinyl alcohol (trade name: EVAL), and the like.
- EVAL ethylene and vinyl alcohol
- a double layer or triple layer (multilayer) laminate can also be used as necessary.
- a resin to which a UV absorber has been added may be used to reduce the transmissivity of UV rays.
- the first and second sealing sections 2, 3 that were provided for forming the bag assembly 1 are positioned above the substantially perpendicular line of the first triangle (GG'C) and the second triangle (GG'D) pair in which the fourth sealing section 5 is used as the shared bottom side GG'.
- the first and second sealing sections 2, 3 act as an unsealing guide for tearing of the packaging container 6. When gradually unsealed (torn) along this unsealing guide, a boat shape is formed as shown in FIG. 4 .
- the packaging container spread out to a boat shape has a base length 2h, a height (depth) t at the bow and stern, and forms a boat shape (plate shape) with a depth that is less than t in accordance with the degree of the widening of the boat shape at the center of the boat shape.
- h is obtained by subtracting a width d of the band 13 from the length of the package bag, as shown in FIG. 1 , d is the width of the band 13, and t is the size of half the width of the package bag ABDC.
- a portion of the band 13 forms the ear portion of the boat shape, contributes to holding the shape of the boat, and makes the packaging container convenient to grasp.
- the boat shape produced in this case holds the contents unchanged in the middle of the boat shape and functions as a kind of vessel.
- the boat shape functions as a kind of food vessel, e.g., a plate.
- a suitable dressing is applied, and the lettuce can be eaten using the boat shape as a plate after the package has been unsealed.
- the corners C, D of the original bag ABDCD are positioned in the center of the upper section of the boat shape. Since this portion is a factor that causes the shape of the boat to become unstable, the portions on the periphery of sides C, D are preferably reinforced in advance.
- reinforcement sections indicated by the reference numerals 11, 12 in FIG. 2(a) are provided.
- the reinforcement sections 11, 12 having a triangular shape are being provided to the periphery of the corners C, D.
- substantially the entire triangularly shaped surfaces may be fused, or only the oblique side sections 16, 17 of the triangular shape may be fused, as shown in the drawing. It is also possible to affix a reinforcing material composed of a sheet or a film to the reinforcement sections 11, 12.
- the packaging object is not particularly limited.
- the first sealing section 2 of the side A-C and the second sealing section 3 of the side B-D of the packaging bag ABDC are composed of a folding line, seal line, a perforated line, or the like and act as the unsealing guide. It is preferred that the side A-C and the side B-D that act as the unsealing guide to be machined in advance so as to readily unseal (tear).
- the side A-C and side B-D be acted on with force to form fold lines, thermocompression bonded at a low temperature, or provided with linear holes such as a perforated line to allow for facilitated unsealing (tearing).
- a cut 14 or another perforated line, a hole, or the like positioned on the end section of the band 13 be provided at the center section of the side H-H' and positioned on the extension of the first and second sealing sections 2, 3, which are the unsealing guide, as shown in FIG. 5 , so as to be capable of readily unsealing (tearing) along the side A-C and side B-D of the unsealing guide.
- the contents are, e.g., a salad or a vegetable such as spinach or lettuce
- the contents are, e.g., a salad or a vegetable such as spinach or lettuce
- the first and second sealing sections 2, 3 are formed on two sides that face four sides, and the sealing sections 2, 3 form the fourth sealing section 5 and have a tetrahedral shape.
- the sections are positioned above the perpendicular line of the pair of first and second triangular shapes (GG'C), (GG'D).
- GG'C first and second triangular shapes
- the packaging container 6 can be readily unsealed without the adoption of special means by using the first and second sealing sections 2, 3, which are necessary when the bag assembly 1 is formed.
- FIGS. 6 through 11 show other embodiments of the packaging container according to the present invention.
- FIG. 6 shows a bag assembly 22 that is used as a packaging container 20 of the present embodiment.
- the bag assembly 22 is a single long narrow film or sheet folded at the lower end to form superimposed rectangle shapes, and a first and second sealing sections 24, 26 are formed at the pair of two sides (side surfaces) facing each other.
- a transparent, semi-transparent, or colored resin film or resin sheet as the material of the bag assembly 22, a double layer or triple layer laminate can also be used as necessary and a resin to which a UV absorber has been added may be used to reduce the transmissivity of UV rays.
- first and second sealing sections 24, 26 are formed by a heat seal line in which the end surfaces of the film (sheet) have been fused together by cutting the film (sheet) with a hot blade.
- the sealing sections 24, 26 may be a heat seal line in which the surfaces of the film are bonded to each other by thermocompression in lieu of a heat-seal line between end surfaces.
- the bag assembly 22 has a third sealing section 28 composed of a fold line formed on one side (lower end) of the remaining two sides, and the remaining one side (upper end) is open.
- a pair of arcuate corner-pull seal lines 30a, 30b is provided at the two ends of the third sealing section 28.
- the corner-pull seal lines 30a, 30b are composed of thermocompression-bonded seal lines.
- One of the corner-pull seal lines 30a is formed so as to connect between the first sealing section 24 and the left end side of the third sealing section 28, and the other corner-pull seal line 30b is formed so as to connect between the second sealing section 26 and the right end side of the third sealing section 28.
- the third sealing area 28 may be a seal line formed by thermocompression bonding in lieu of a fold line.
- the leafy vegetables V may be a cut vegetable in which, e.g., lettuce, spinach, broccoli, Japanese mustard spinach, green soybean, or any type of leafy vegetable has been cut to the prescribed size.
- the vegetables are arranged in a diameter of about, e.g., 5 to 10 cm, and the leafy vegetables V are randomly placed so that portions overlap each other.
- the upper end opening of the bag assembly 22 is sealed when placement of the leafy vegetables V is completed.
- the sealed state of the bag assembly 22 is shown in the FIGS. 8 and 9 .
- the open section of the bag assembly 22 is sealed by forming a fourth sealing section 32.
- the fourth sealing section 32 is formed by, e.g., a thermocompression-bonded seal line, and is formed at an angle that is substantially orthogonal to the third sealing section 28.
- the fourth sealing section 32 is disposed in a position that is set at a distance downward from the upper end of the bag assembly 22, and an ear section (band) 34 is provided to the upper end of the fourth sealing section 32. Additionally, in the case of the present embodiment, a pair of arcuate corner-pull seal lines 36a, 36b is provided to the two ends of the fourth sealing section 32.
- the corner-pull seal lines 36a, 36b are composed by a thermocompression-bonded seal line in the same manner as the above-described seal lines 30a, 30b.
- One of the corner-pull seal lines 36a is formed so as to connect between the first sealing section 24 and the left end side of the fourth sealing section 32
- the other corner-pull seal line 36b is formed so as to connect between the second sealing section 26 and the right end side of the fourth sealing section 32.
- the pair of first and second substantially triangular shapes a, b that have the fourth sealing section 32 as the common bottom side (described as substantially triangular because the arcuate corner-pull seal lines 36a, 36b are interposed between the oblique side and the bottom side of the triangle)
- the pair of third and fourth substantially triangular shapes c, d that have the third sealing section 28 as the common bottom side (described as substantially triangular because the arcuate corner-pull seal lines 30a, 30b are interposed between the oblique side and the bottom side of the triangle) are formed.
- the substantially triangular shapes a through d have the oblique sides connected in the circumferential direction to form a tetrahedral shape, and act as the packaging container 20 in which the leafy vegetable V as the packaging object is sealed inside together with air.
- the first and second sealing sections 24, 26 are positioned on the substantially perpendicular line of the first and second substantially triangular shapes a, b, as shown in FIG. 8 , and the thermocompression bond or the hot-blade seal line are used as the unsealing guide for tearing of the packaging container 20.
- FIG. 11 shows a state in which the packaging container 20 has been torn along the seal line wherein the first and second sealing sections 24, 26 are used as the unsealing guide.
- a notch 38 positioned on the extension line of the sealing section 24, 26 is provided in the center position of the ear section (band) 34 in order to further facilitate the tearing operation.
- a boat-type shape is formed using the third and fourth substantially triangular shapes c, d as the bottom side and the side surfaces erected at the rim when the first and second sealing 24, 26 are torn to the position of the corner-pull seal lines 30a, 30b, respectively, as shown in FIG. 11 .
- the side surfaces in this case are formed by dividing the first and second substantially triangular shapes a, b on a substantially perpendicular line.
- the leafy vegetable V placed inside the packaging container 20 is inside the boat shape, and the upper area of the boat shape is open.
- the body can therefore function as a boat-shaped plate, and the vegetables can be eaten without further preparation.
- the packaging container 20 configured in the manner described above, since the packaging container 20 that has air sealed in together with lettuce, spinach, or another leafy vegetable V is provided with the corner-pull seal lines 30a, 30b, 36a, and 36b at all corner sections of the tetrahedral body, the corner sections in which leafy vegetable V enter and are readily damaged are eliminated, and, as a result, the freshness of the leafy vegetable can be maintained for a long time.
- the first and second sealing sections 24, 26 composed of a heat-seal line formed on two opposing sides of the four sides thus form the fourth sealing section 32 and present a tetrahedral shape in the case that the bag assembly 22 that has one open side is formed.
- the sections are positioned on a perpendicular line of the pair of first and second triangular shapes c, d, and as a result, the heat-seal lines can be used as an unsealing guide for tearing.
- lettuce, spinach, or another leafy vegetable V is the packaging object, and when this object is sealed inside the packaging container 20 whose basic shape is a tetrahedral body, the body does not have parallel or opposing surfaces. Therefore, when an external force is applied, the external force is dispersed, and damage to the leafy vegetable can be reduced without external force being applied unchanged to the leafy vegetable V as in the case where the vegetables are sealed in a box-shaped packaging container.
- lettuce, spinach, or another leafy vegetable V is the packaging objec sealed together with air inside the packaging container 10 whose basic shape is a tetrahedral body. Therefore, air layers are interposed between adjacent vegetables and between the vegetables on the surface and the bag assembly 12. Accordingly, when external force is applied, the air layers function as a cushion and can act to reduce damage to the leafy vegetable.
- corner-pull seal lines 30a, 30b, 36a, 36b are formed in an arc and each of the seal lines can be straight lines, as shown by the alternate long and short dash line in, e.g., FIGS. 6 and 8 .
- the marginal portions of the external sides of each corner-pull seal line 30a, 30b, 36a, 36b that are shown by an imaginary line in FIGS. 6 and 8 can be cut away and removed along the seal lines or may be left unchanged.
- the packaging object described as a leafy vegetable is not limiting and may also be a readily damaged object, e.g., potato chips or another food item; beads or another sundry item; or the like.
- the packaging container of the present invention using a sealing section required when the bag assembly is formed makes it possible to unseal the bag assembly more easily without adopting special means, to reduce labor and costs, to further enhance value as a packaging container, and to widely use the packaging container in the industrial field.
