The contents 4 are hatched. In these drawings, the y direction corresponds to the first direction of the present invention, and the x direction corresponds to the second direction of the present invention.

  The first main plate portion 1A and the second main plate portion 1B face each other and are joined to each other by providing the joint portion 2. In this embodiment, the case where the 1st main board part 1A and the 2nd main board part 1B consist of the same sheet material selected from the various sheet materials which consist of resin mentioned later is demonstrated to an example. For this reason, the first main plate portion 1 </ b> A and the second main plate portion 1 </ b> B have the same thickness at the joint portion 2. In the present embodiment, the first main plate portion 1A and the second main plate portion 1B are not connected to each other except that they are joined by the joint portion 2. Unlike this, the end edge of the first main plate portion 1A and the end edge of the second main plate portion 1B may be connected by a folded portion or the like. Alternatively, the first main plate portion 1A and the second main plate portion 1B may be made of different materials.

  The first main plate portion 1A has a first shell portion 11A and a first annular portion 12A. The first shell portion 11A is a portion where the first main plate portion 1A is partially processed into a bulging shape. The first annular portion 12A is a flat portion surrounding the first shell portion 11A. In the present embodiment, the first annular portion 12A surrounds the first shell portion 11A over the entire circumference. The first annular portion 12A is not limited to the one that completely surrounds the entire circumference of the first shell portion 11A. For example, the first annular portion 12A may have a discontinuous portion, and the first shell portion 11A may be exposed to the outside in plan view from the discontinuous portion.

  In the present embodiment, the first shell portion 11A has a main body shell portion 111A and a dispensing shell portion 112A. The main body shell portion 111A is a portion having a relatively large capacity with respect to the extraction shell portion 112A. The main body shell portion 111A and the extraction shell portion 112A are connected to be adjacent in the y direction. Further, in the present embodiment, the extraction shell portion 112A is located at the approximate center of the first main plate portion 1A in the y direction, and the main body shell portion 111A is located near the lower end in the y direction.

  The shape and size of the main body shell 111 </ b> A are not particularly limited, and various forms are possible depending on the properties of the contents 4, the sales promotion policy of the package A <b> 1, and the like. In the illustrated example, the main body shell 111A has a substantially rectangular shape in plan view. The main body shell portion 111A has a multi-step portion 115A. The multi-step portion 115A is a portion where the side surface of the main body shell portion 111A is formed in a step shape.

  The shape and size of the extraction shell 112A is not particularly limited as long as the extraction shell 112A has a relatively small capacity with respect to the main body shell 111A and is connected so as to be adjacent to each other in the y direction. It is set as various aspects according to the property of this, the sales promotion policy of the package A1, and the like. In the illustrated example, the extraction shell portion 112A has a shape that is elongated in the y direction. In the present embodiment, a peak 113A is formed in the extraction shell 112A. The ridge portion 113A has a convex shape that has a cross-sectional shape in the zx plane that is steep on the side away from the second main plate portion 1B in the z direction, and extends as a whole in the y direction.

  In the present embodiment, a planned cutting line 17 is formed on the first main plate portion 1A. The planned cutting line 17 is a line that prompts the cutting of the first main plate portion 1A. For example, the line portion of the first main plate portion 1A is thinner than the surrounding portion by so-called half cut or the like. The planned cutting line 17 crosses the extraction shell portion 112A in the x direction. Further, in the illustrated example, the planned cutting line 17 crosses the first main plate portion 1A in the x direction, and is provided substantially at the center in the y direction of the first main plate portion 1A.

  The second main plate portion 1B has a second shell portion 11B and a second annular portion 12B. The second shell portion 11B is a portion where the second main plate portion 1B is partially processed into a bulging shape. The second annular portion 12B is a flat portion surrounding the second shell portion 11B. In the present embodiment, the second annular portion 12B surrounds the second shell portion 11B over the entire circumference. The second annular portion 12B is not limited to the one that completely surrounds the entire circumference of the second shell portion 11B. For example, the second annular portion 12B may have a discontinuous portion, and the second shell portion 11B may be exposed to the outside in plan view from the discontinuous portion.

  The second shell portion 11B has a shape that substantially matches the main body shell portion 111A of the first shell portion 11A in plan view. In the illustrated example, the second shell portion 11B has a semi-elliptical column shape. Moreover, in the example shown in figure, it has a small site | part which protrudes upwards in a y direction view so that FIG. 2 and FIG. 4 may understand.

  Moreover, in this embodiment, the notch part 16 is formed in the 1st main board part 1A and the 2nd main board part 1B. The cutout portion 16 is a portion where the first annular portion 12A of the first main plate portion 1A and the second annular portion 12B of the second main plate portion 1B are recessed in the x direction. In the illustrated example, a pair of notches 16 are provided on both sides in the x direction, and each notch 16 has a substantially triangular shape. Further, the pair of notches 16 are disposed at the approximate center in the y direction of the first main plate portion 1A and the second main plate portion 1B. The planned cutting line 17 provided on the first main plate portion 1 </ b> A reaches the pair of cutout portions 16.

  The joint portion 2 is a portion that fixes the first main plate portion 1A and the second main plate portion 1B to each other. Of the first annular portion 12A and the second main plate portion 1B of the first main plate portion 1A, the first annular portion 12A. And a portion facing each other are joined. In the present embodiment, the joint portion 2 is formed by joining the regions of the first annular portion 12A of the first main plate portion 1A and the second annular portion 12B of the second main plate portion 1B that are in contact with each other without being separated from each other. It has been done. Although the method of joining the first annular portion 12A and the second annular portion 12B is not particularly limited, for example, heat sealing can be used. By providing the joint portion 2, the housing portion 3 is hermetically sealed. In addition, the joining method for providing the junction part 2 is not specifically limited, The technique which can join the 1st main board part 1A and the 2nd main board part 1B appropriately can be employ | adopted suitably. Examples of such a method include a method of applying an adhesive, a method of interposing an adhesive layer such as an adhesive tape, in addition to the above-described heat sealing.

  The accommodating portion 3 is defined by the first shell portion 11A of the first main plate portion 1A and the portion of the second main plate portion 1B that faces the first shell portion 11A. The accommodating part 3 of this embodiment has the main-body part 31 and the extraction | pouring part 32. FIG. The main body 31 is a part where the content 4 is mainly stored. In the present embodiment, the main body portion 31 is defined by the main body shell portion 111A and the second shell portion 11B of the first shell portion 11A, as clearly shown in FIG. The main body 31 has a volume sufficient to accommodate the contents 4 to be stored. The shape of the main body 31 can be various shapes depending on the shapes of the main body shell 111A and the second shell 11B.

  The extraction part 32 is a part connected to the main body 31 so as to be adjacent to the main body 31 in the y direction. As shown in FIG. 4, the extraction portion 32 is defined by the extraction shell portion 112A of the first shell portion 11A and a part of the second annular portion 12B. For this reason, the extraction | pouring part 32 is a small capacity | capacitance relatively with respect to the main-body part 31, and is the shape elongated in the y direction in the example shown in figure. Moreover, as shown in FIG. 4, it can be said that the 2nd cyclic | annular part 12B which is a flat part of the 2nd main board part 1B is arrange | positioned in the position which faces the extraction shell part 112A in az direction. Since the planned cutting line 17 is provided so as to cross the extraction shell 112A of the first shell portion 11A in the x direction as described above, the planned cutting line 17 is connected to the extraction portion 32 of the storage unit 3. Cross in the x direction.

  The sheet material constituting the first main plate portion 1A and the second main plate portion 1B having such a configuration is a forming method for the first shell portion 11A and the second shell portion 11B, which will be described later, and a joining method for forming the joint portion 2. A sheet material capable of appropriately performing the above is selected. For example, the material constituting the base material that is the main part of the sheet material includes polyester resins such as polyethylene terephthalate, polyolefin resins such as polypropylene and polyethylene, polystyrene resins, polyamide resins, and synthetic resins such as polyvinyl chloride. May be used singly or in combination of two or more. Examples of the base material for the sheet material include a single-layer synthetic resin sheet of the resin and a laminated sheet in which a plurality of the same or different synthetic resin sheets are laminated. As these synthetic resin sheets, if necessary, a synthetic resin sheet on which a metal or a metal oxide is deposited or a sheet having a gas barrier function such as ethylene-vinyl alcohol (EVOH) may be used. Further, the sheet material is preferably transparent or translucent in order to see through the stored contents 4, but a non-transparent material may be used. Furthermore, a design such as a trade name may be printed on the sheet material as necessary. In the illustrated example, as shown in FIG. 1, for example, a product name is printed in a region of the first annular portion 12A of the first main plate portion 1A located on the opposite side to the main body shell portion 111A in the y direction. ing. In addition, as shown in FIG. 2, for example, a barcode used for merchandise management or the like is provided in a region located on the opposite side in the y direction to the second shell portion 11B of the second annular portion 12B of the second main plate portion 1B. It is printed. The thickness of sheet material is not specifically limited, For example, it is 0.05-1.0 mm, Preferably it is 0.1-0.6 mm. In the present embodiment, a case where polyethylene terephthalate is used as a suitable material constituting the first main plate portion 1A and the second main plate portion 1B will be described as an example.

  Further, the first main plate portion 1A and the second main plate portion 1B are formed by processing a substantially unstretched sheet material as will be described later. Here, “substantially unstretched” means that the film has not been actively stretched. “Actively stretched” means that the film is stretched by a known and conventional stretching machine such as a roll stretching machine or a tenter. In the actual sheet manufacturing process, for example, when the sheet material is wound, there is a case where the sheet material is unavoidably stretched because tension is applied in the winding direction, but such a case is not included in the stretching. Specifically, the draw ratio is preferably 1.2 times or less, and more preferably 1.1 times or less. Then, for example, through the manufacturing process described later, as shown in FIG. 10, the first annular portion 12A is maintained in a substantially unstretched state, and the extraction shell portion 112A is stretched in the y direction. It is formed by the resin sheet which made the resin material made into the main material. Here, the main material is, for example, when a gist sheet having a plurality of layers is used, the mechanical strength characteristics and cutting properties of the resin sheet are determined predominantly by a layer made of a certain material. It means that Such a layer specifying the main material generally occupies most of the thickness of the resin sheet.

  The contents 4 are liquids and gels represented by foods such as seasonings, beverages, cosmetics, and medicines. The specific configuration of the contents 4 is not particularly limited. The contents 4 are mainly stored in the main body 31 of the housing 3.

  Next, an example of a method for manufacturing the package A1 will be described below with reference to FIG.

  In the figure, the sheet material 1 which is the material of the first main plate portion 1A and the second main plate portion 1B is conveyed from the left to the right in the drawing. As the sheet material 1, the above-described sheet material is appropriately adopted. The sheet material 1 that has not yet been processed for producing the package A1 is an unstretched resin sheet. In addition, before performing the process described below, it is preferable to appropriately print the above-described product name, bar code, and the like on the sheet material 1.

  First, as shown in FIG. 2A, for example, a strip-shaped sheet material 1 wound up in a roll shape is sequentially fed out. And the process which folds in the width center of the sheet material 1 is given. Thereby, the sheet material 1 is connected via the folded-back portion 181 and has a state of having the long first main plate portion 1A and the second main plate portion 1B facing each other. Further, immediately after the folding process, a so-called half-cut process is performed on the outer surface of the first main plate portion 1A by the cutter Ct disposed on one side (the first main plate portion 1A side) of the sheet material 1. Thereby, the 1st main board part 1A is provided with the cutting projected line 17 extended in a conveyance direction. The second main plate portion 1B is not subjected to half cut processing.

  Next, in FIG. 2B, the joining portion 2 is formed by performing heat sealing. For example, a mold (not shown) set at a predetermined temperature is used for the seat seal. At this time, an unjoined portion 182 that is not heat-sealed is provided on a part of the sheet material 1. FIG. 9 is an enlarged plan view of a main part showing the first main plate portion 1A in FIG. Since the sheet material 1 is an unstretched resin sheet, the first main plate portion 1A is random in the orientation direction of the resin fibers in both the first annular portion 12A constituting the joint portion 2 and the unjoined portion 182. is there. A plurality of short thin lines in the figure conceptually show resin fibers whose orientation directions are random.

  Next, as shown in FIG. 3C, for example, a gas is blown into the unjoined portion 182 using a nozzle (not shown) in a state where the first main plate portion 1A and the second main plate portion 1B are sandwiched by a mold (not shown). This gas is, for example, compressed air or nitrogen gas. The gas may be a high-temperature gas in order to promote deformation of the first main plate portion 1A and the second main plate portion 1B. Thereby, the part which was the unjoined part 182 becomes the 1st shell part 11A, the 2nd shell part 11B, and the filling port 183. The main body shell portion 111A and the second shell portion 11B of the first shell portion 11A define a space that becomes the main body portion 31 of the housing portion 3 in the package A1. The extraction shell portion 112A and the second main plate portion 1B of the first shell portion 11A define a space that becomes the extraction portion 32 in the package A1.

  FIG. 10 is an enlarged plan view of a main part showing the first main plate portion 1A after going through FIG. In the step of forming the first shell portion 11A, the portion of the unjoined portion 182 that is elongated in the y direction is deformed into a bulging shape in the step of forming the first shell portion 11A. In this deformation, stretching in the x direction is remarkably dominant, and stretching in the y direction is weak enough to be ignored. For this reason, the extraction shell portion 112A has a configuration formed by a resin sheet stretched in the x direction. In the drawing, a plurality of short thin lines along the x direction attached to the extraction shell portion 112A conceptually show resin fibers aligned in the x direction by stretching. On the other hand, the first annular portion 12A constituting the joint portion 2 hardly extends in the formation of the first shell portion 11A. For this reason, the state where the first annular portion 12A is formed by the unstretched resin sheet is maintained.

  Next, as shown in FIG. 4D, for example, a predetermined amount of the content 4 is filled into the main body 31 of the housing portion 3 from the filling port 183 using the nozzle Nz. And as shown to the figure (e), the filling port 183 is sealed by giving a heat seal, for example. The filling port 183 sealed by heat sealing becomes a part of the joint portion 2. Then, as shown in FIG. 5F, the first main plate portion 1A and the second main plate portion 1B are cut along the cutting line Cl. Thereby, package A1 shown in Drawing 1-Drawing 7 is obtained.

  Next, opening of the package A1 will be described below.

  1-4, for example, fingers are put on both ends of the first main plate portion 1A and the second main plate portion 1B in the y direction with the extraction shell portion 112A (the extraction portion 32) of the package A1 shown in FIGS. . Then, by applying force so as to grip the package A1 with these fingers, a bending moment is applied to the package A1 so that the first main plate portion 1A is on the outside of the bend and the second main plate portion 1B is on the inside of the bend. . Due to this bending moment, a tensile stress is generated in the first main plate portion 1A on the outer side according to the position in the y direction. The tensile stress increases toward the center in the y direction of the first main plate portion 1A.

  In the present embodiment, an extraction shell 112A is provided at the center of the first main plate 1A in the y direction. The extraction shell portion 112A is a portion extending in the x direction, and the resin fibers are arranged in the x direction as shown in FIG. For this reason, the extraction shell portion 112A has a property of being easily cut along a line parallel to the x direction. In the extraction shell portion 112A, a planned cutting line 17 that crosses in the x direction is formed. For this reason, the extraction shell portion 112 </ b> A is cut along the planned cutting line 17, and this cutting crosses the first main plate portion 1 </ b> A along the planned cutting line 17. As a result, as shown in FIG. 11 and FIG. 12, the package A1 is folded in a double fold shape, and the extraction shell portion 112A (the extraction portion 32) is opened. Subsequently, when the main body shell portion 111A is crushed with a finger, the contents 4 stored in the main body portion 31 can be poured out from the opening portion of the extraction shell portion 112A.

  Next, the operation of the package A1 will be described.

  According to this embodiment, as shown in FIGS. 11 and 12, the package A1 can be quickly opened by folding the package A1 in half so that the extraction shell portion 112A is on the outside. . In this unsealing, while the pour shell portion 112A is cut, the second main plate portion 1B inside the pour shell portion 112A is not provided with the planned cutting line 17, so there is a possibility that it will be cut clearly. Low. For this reason, the contents 4 can be poured out in a desired direction from the opening portion of the pouring shell 112A facing outward. Therefore, it is possible to suppress the contents 4 from being scattered in an unintended direction during opening.

  By providing the planned cutting line 17 that crosses the extraction shell part 112A, the extraction shell part 112A can be quickly and reliably cut along the planned cutting line 17. Moreover, by providing the peak 113A in the extraction shell 112A, the bending rigidity of the extraction shell 112A is increased. Thereby, if a bending moment is given at the time of opening, the bending | flexion of the whole extraction shell part 112A will be suppressed, and a high stress will concentrate on the cutting projected line 17. FIG. This is convenient for cutting along the planned cutting line 17. Furthermore, by providing the pair of notches 16, the stress concentration on the planned cutting line 17 can be further increased.

  By providing the multi-step portion 115A on the main body shell portion 111A, the main body shell portion 111A has a structure that is easily crushed when pressed in the z direction. In particular, when the multistage portion 115A is not provided, if a force is applied to the main body shell portion 111A, the main body shell portion 111A may be rapidly deformed as soon as the force exceeds a certain magnitude. This can cause a sudden splash of the contents 4. When a force is applied, the main body shell portion 111A having the multistage portion 115A is gradually deformed according to the magnitude of the force. For this reason, it is possible to avoid the contents 4 from being suddenly scattered, and the contents 4 can be slowly poured out.

  As shown in FIGS. 11 and 12, the package A1 folded in half for opening is shaped to be supported at two locations on both ends in the y direction of the first main plate portion 1A and the second main plate portion 1B. Yes. For this reason, the package A1 in which the contents 4 of the opened package remain can be made independent.

  The packaging body A1 is folded in half by making the lengths in the y direction of the first main plate portion 1A and the second main plate portion 1B located on both sides in the y direction across the planned cutting line 17 (the extraction shell portion 112A). Can be easily performed. Further, by increasing the lengths in the y direction of the first main plate portion 1A and the second main plate portion 1B located on the opposite side of the main body shell portion 111A in the y direction, product names, lot numbers, bar codes, etc. are printed. The print area can be enlarged. In particular, in the above-described conventional packaging body, since the pouring part is twisted and opened, if the important information indicating the individual information of the packaging body such as a lot number or a barcode is described in the part to be cut, the individual information is stored in the container. Lost from the body. On the other hand, in the case of the package according to the present invention, since there is no portion that is excised at the time of opening, there is no restriction on the location to which these important information is given, and the degree of freedom in design design can be secured.

  13 to 23 show another embodiment of the present invention. In these drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment.

  FIG. 13 shows a modification of the package A1. In this modification, the lengths in the y direction of the first main plate portion 1A and the second main plate portion 1B are asymmetric with respect to the planned cutting line 17.

According to such a modification, the stress concentration on the planned cutting line 17 can be further increased, and the opening can be more reliably performed.

  FIG. 16 shows another modification of the package A1. In the present modification, the planned cutting line 17 is not provided in the first main plate portion 1A. Even in such a modification, when the package A1 is folded in half, a corresponding stress is concentrated on the extraction shell 112A. Due to this stress, the extraction shell 112A in which the resin fibers are aligned in the x direction can be cut along the x direction. Therefore, it is possible to suppress the contents 4 from being scattered in an unintended direction during opening.

  FIG. 17 shows another modification of the package A1. In this modification, although the planned cutting line 17 is provided, the notch 16 is not provided in the first main plate 1A and the second main plate 1B. In addition, the peak portion 113A is not provided in the extraction shell portion 112A, and the cross-sectional shape is, for example, a semicircular shape. Also in this modified example, when the package A1 is folded in half, stress concentrates on the planned cutting line 17 crossing the extraction shell portion 112A, and the cutting can be performed along the planned cutting line 17. Further, even if the extraction shell portion 112A is not provided with the ridge portion 113A, the resin fibers of the extraction shell portion 112A are aligned in the x direction, so that when stress of a predetermined value or more occurs, the x direction Can be cut along. Providing the planned cutting line 17 is preferable for reliable cutting.

  Of course, the configurations of these modified examples can be appropriately combined with each other. Moreover, the structure of these modifications can be suitably employ | adopted for embodiment described below.
