(Basic configuration)
First, a basic configuration of a package according to the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view showing a schematic configuration of a package according to the present invention, and FIG. 2 is an exploded perspective view of the package shown in FIG. FIG. 3 is a cross-sectional view taken along line III-III shown in FIG.

  The package 1 is used as a refill package for packaging powdery or liquid materials and refilling the contents into other storage containers. The packaging container 2 and the inside of the packaging container 2 are filled. And a membrane 3 for sealing the open end 11 of the packaging container 2. Furthermore, an overcap 4 formed of high density polyethylene (HDPE), polypropylene (PP) or the like is attached to the packaging container 2 in order to protect the membrane 3. The content 5 is not particularly limited as long as it has fluidity, and the packaging container 2 according to the present invention can be applied to various materials such as powder, granule, and liquid.

  The packaging container 2 includes a cylindrical container body 10 with one end opened, and a funnel part 8 including a funnel 20 housed inside the container body 10.

  The container body 10 has a side wall 17, a bottom portion 16, and an open end 11. In this embodiment, the container main body 10 is formed in a cylindrical shape by rounding rectangular sheet materials, partially overlapping them, and bonding the overlapping portions. The bottom portion 18 of the container body 10 includes a circular bottom plate 19 and a folded portion 18 that sandwiches and holds the outer peripheral portion of the bottom plate 19. On the other hand, a curling 12 is formed at the open end 11 of the container body 10 by bending a part of the side wall 17 outward and winding it in an annular shape.

  The material for forming the container body 10 is not particularly limited, but it is preferable to use a material mainly made of paper in consideration of weight reduction of the container, ease of disposal, and resource saving. As an example, in food packaging applications, low-density polyethylene (LDPE), polyethylene terephthalate (PET), aluminum foil, and paper are laminated in order from the side that is the inner surface of the container body 10, and high gas barrier properties (particularly Sheet material having a property of blocking volatile components derived from contents such as oxygen, water vapor and aromatic components).

  The funnel part 8 refers to a part composed of a funnel having a portion whose diameter decreases toward one end and a member integrated with the funnel. The funnel part 8 illustrated in FIGS. 1 to 3 includes a funnel 20 and a cylindrical side wall 22 connected to the wide mouth portion of the funnel part 8, and is inserted into the container body 10 from the open end 11 and accommodated therein. The container 10 is fitted. As will be described later, the funnel 20 is provided for facilitating the refilling of the contents 5 into the storage container, and is arranged so that the diameter decreases toward the open end 11. The taper angle α of the funnel 20 is appropriately set according to the fluidity of the contents, but when the contents are powder, it is set to at least 20 to 45 °, more preferably 20 °.

  The funnel part 8 may be integrally formed of a resin material such as HDPE or PP, for example, or may be configured by connecting a funnel 20 and a side wall 22 separately formed using paper, resin, paper mixed resin, or the like. May be. When resin or paper mixed resin is used, the funnel part 8 may be formed by, for example, injection molding. The shape and attachment method of the funnel 20 and the funnel part 8 are not limited to the examples of FIGS.

  4 is a plan view of the membrane shown in FIG. 2, and FIG. 5 is a cross-sectional view taken along line VV shown in FIG.

  The membrane 3 is used to seal the open end 11 of the packaging container 2 after the packaging container 2 is filled with the material. Depending on the use of the packaging container 2, the sheet material is formed of a single layer. Or the sheet material which laminated | stacked several layers can be utilized. When the content of the packaging container 2 is food or the like, it is preferable to form the membrane 3 with a material having gas barrier properties.

  Specifically, as shown in FIG. 5, the membrane 3 is made of resin through a sealant layer 31 sealed in the packaging container 2, a resin layer 32 laminated on the sealant layer 31, and an adhesive layer 33. And a metal foil layer 34 laminated on the layer 32. As an example, the sealant layer 31 may be formed of polyethylene, the resin layer 32 may be formed of polyethylene terephthalate (PET), and the metal foil layer 34 may be formed of aluminum. The number of layers and the stacking method of the layers constituting the membrane 3 are not particularly limited and may be arbitrary.

  The membrane 3 is formed with six cutting lines 30 extending radially from the center so as to be broken when the tension exceeds a predetermined magnitude due to external pressure. 4 and 5, the cutting line 30 cuts only the sealant layer 31 and the resin layer 32 in the thickness direction of the membrane 3, and draws a broken line in the extending direction of the membrane 3. Is formed.

  The cutting line 30 is for adjusting the breaking strength of the membrane 3, and according to the pressing force applied to the membrane 3, the number, the line shape, the length and depth of the cutting part can be arbitrarily set. it can. As an ideal number of the cutting lines 30, it is desirable to provide 3 to 10 radial lines from the center. The cutting line 30 may be linear or curved. Moreover, in the extending | stretching direction of the membrane 3, the cutting line 30 does not necessarily need to be a broken line perforation, and you may form it so that a continuous line may be drawn.

  6 is a perspective view showing a usage state of the package according to the present invention, and FIG. 7 is a cross-sectional view taken along the line VII-VII shown in FIG. More specifically, in FIGS. 6 and 7, (a) shows a state before the membrane is ruptured, and (b) shows a state after the membrane is ruptured.

  When the storage container 7 is refilled with the contents 5 in the package 1, first, as shown in FIGS. 6 (a) and 7 (a), the packaging container 2 with the overcap removed is inverted, and the membrane 3 Is brought into contact with the opening of the storage container 7. At this time, since the opening on the narrow mouth side of the funnel 20 is disposed within the range of the opening of the storage container 7, the center of the packaging container 2 is aligned with the center of the storage container 7.

  Next, the bottom of the package 1 is pushed in the direction of the arrow in the figure. At this time, the membrane 3 receives a pressing force from the opening of the funnel 20 and the container 7 as the packaging container 2 is pressed. When the tension of the membrane 3 exceeds a predetermined breaking strength, FIG. As shown in FIG. 7 (b), the membrane 3 is broken. When the membrane 3 is broken, the funnel 20 is inserted into the container 7 according to the pressing force applied to the packaging container 2, and the broken membrane 3 is folded into a space sandwiched between the funnel 20 and the side wall 22. . As a result, the opening on the outer side of the funnel 20 is greatly opened, so that the content 5 flows into the container 7 along the taper of the funnel 20 according to gravity.

  As described above, according to the packaging container 2 and the package 1 using the same according to the present invention, the membrane 3 and the opening of the container 7 are brought into contact with each other, and the packaging container 2 is pressed toward the storage container 7. Accordingly, the opening of the funnel 20 is inserted into the storage container 7 almost simultaneously with the breakage of the membrane 3. Since the contents 5 in the packaging container 2 are guided into the storage container 7 by the funnel 20, it is possible to prevent the contents 5 from being scattered or spilled during the refilling operation. Therefore, according to the packaging container 2 and the package 1 which concern on this embodiment, it becomes possible to refill the contents easily.

  Hereinafter, a funnel part according to an embodiment of the present invention, a packaging container and package using the funnel part, and a manufacturing method will be described. In the drawings described below, an overcap for protecting the membrane is not shown.

(Embodiment)
FIG. 8 is a perspective view of the package according to the embodiment of the present invention, and FIG. 9 is a cross-sectional view taken along line A ₄ -A ₄ ′ shown in FIG.

  The package 401 according to the present embodiment includes a funnel part 410, a container body 450, contents 460, and a membrane 470.

  The funnel part 410 includes a funnel 420 for guiding the contents 460 to a storage container, a cylindrical side wall 430 joined to the container body 450, and a rib 440 for reinforcing the funnel part 410.

  The funnel 420 includes an opening 421 on the wide-mouth side and an opening 422 on the narrow-mouth side, and has a shape whose diameter decreases from the opening 421 to the opening 422, and a part including the opening 422 is straight. have.

  The side wall 430 has a cylindrical shape surrounding the funnel 420, and a plurality of rectangular openings for stealing meat are intermittently formed in the circumferential direction.

  The rib 440 is connected to the outer surface of the funnel 420 and the inner surface of the side wall 430 and is intermittently disposed in the circumferential direction.

  The container main body 450 has a cylindrical shape with an open end and a bottom, and a flange that projects vertically outward is provided at the open end. This flange is formed by bending the edge portion of the side wall of the container body 450 multiple times outward to form a layer, bending the edge of the side wall outward, and providing a curling that is rolled around the outer periphery, or flattening the curling. It can be formed by crushing.

  The funnel part 410 is fitted into the open end of the container body 450 and filled with the contents 460, and then the open end is sealed with the membrane 470. Since the package according to the present invention is assumed to be used as described above (FIGS. 6 and 7), the membrane 470 is formed with a cutting line 471 for adjusting the breaking strength.

  As shown in FIG. 9, in the funnel part 410 according to this embodiment, the opening 422 on the narrow mouth side of the funnel 420 protrudes by a dimension D from the plane including the side wall end surface 431 constituting the open end of the container body 450. Yes.

  When curling or the like is formed at the open end of the container main body 450, the inner diameter of the open end side of the container main body 450 is smaller than the inner diameter of other portions, and the funnel part 450 is inserted into the container main body 450. Resistance. However, as described above, the height of the side wall 430 (in the direction of the central axis) is designed to be smaller than the height (in the direction of the central axis) from the wide-mouth side to the narrow-mouthed side of the funnel 420. Since the time required to insert 410 can be shortened and the amount of resistance received by the side wall 430 can be reduced, the funnel part 410 can be easily fitted into the open end of the container body 450. At this time, when the dimension D is 3 mm or more, the fitting is further facilitated.

  As shown in FIG. 9, the opening 422 on the narrow mouth side of the funnel 420 protrudes from the plane including the end surface 451 of the container body 450 by the dimension D1. With this configuration, the opening 422 and the inner surface of the membrane 470 are kept in close contact with each other.

  The dimension of D1 is preferably set to 5 mm or less. If D1 exceeds 5 mm, the possibility that the opening 422 on the narrow mouth side of the funnel 420 breaks through the membrane 470 increases. Further, if D1 is within a range of −2 mm, the contents 460 of the package 401 do not go outside the funnel 420 during transportation or the like, and the contents 460 do not leak outside when the package 401 is opened. In addition, when D1 is a negative value, it means that the opening 422 is located on the bottom side of the container body 450 with respect to the plane including the end surface 451 of the container body 450.

  However, when the particle size of the contents 460 is small (when the diameter is 2 mm or less), the content of D1 is less than 0 mm (the open end of the container body 450 and the narrow end of the funnel 420 are at the same level). The object 460 may go outside the funnel 420 and the contents 460 may leak outside when the package 401 is opened. Therefore, in order to effectively prevent such wraparound, the dimension of D1 is set to 0 mm or more and 5 mm or less, more preferably 0.5 mm or more and 5 mm or less. When D1 is within this range, the end surface 423 on the narrow mouth side of the funnel 420 presses against the membrane 470 and the gap between the two is filled. Therefore, even if the content 460 has a small particle size, the content 460 does not go outside the funnel 420.

  On the other hand, the side wall end surface 431 of the funnel part 410 is positioned on the bottom side of the container main body 450 by the dimension D2 with respect to the plane including the end surface 451 of the container main body 450.

  FIG. 10 is a schematic diagram showing a deformed state of the package shown in FIG.

  When the package 401 falls with the open end of the container main body 450 directed obliquely downward, as shown in FIG. 10, a pressing force in the direction of the arrow in the figure is applied to the package 401 that has collided with the ground. If the attachment position of the funnel parts is set as in this embodiment, only the vicinity of the open end of the container body 450 is partially deformed to absorb the impact, and no tension is generated in a wide range with respect to the membrane 470. Breakage of the membrane 470 is suppressed. On the other hand, in a package in which the end surface 431 of the side wall of the funnel 420 is flush with the end surface 451 of the container body 450 (D2 = 0), when a pressing force is applied near the open end of the container body 450, the funnel part 410 together with the container body 450 Is deformed. As a result, tension is generated in a wide range of the membrane 470, and the possibility that the membrane 470 is broken increases.

  FIG. 11 is a graph showing the relationship between the dimension of D2 shown in FIG. 8 and the membrane breakage rate. More specifically, FIG. 11 shows a relationship between D2 and the breakage rate of the membrane 470 by performing a test in which the package 401 is dropped from a position of 60 cm in height with the open end of the container body 450 obliquely downward. Is. This test result is based on the package 401 using the funnel part 410 made of a material having low rigidity such as HDPE.

  As shown in FIG. 11, the fracture occurrence rate of the membrane 470 decreases as the value of D2 increases. Specifically, when D2 is 0 mm, the breaking rate of the membrane 470 is 50%, but when D2 is 3.5 mm or more, the breaking rate of the membrane 470 is set to 0% under the same dropping conditions. Can do.

  When the funnel part 410 is made of a material having high rigidity such as PP or metal, the deformation of the package is prevented by the rigidity of the funnel part 410, so that D2 may be 0 mm or more. However, in the case of using a material that does not have high rigidity such as HDPE, it is preferable to set D2 to 3.5 mm or more based on the above test result in order to prevent unexpected breakage of the membrane 470 at the time of dropping.

  As described above, in the package according to this embodiment, the level difference D1 between the opening 422 of the funnel part 410 and the open end of the container body 450 and the level difference D2 between the side wall end surface 431 of the funnel part 410 are appropriately set. By setting, it becomes possible to effectively prevent the wraparound of the contents and the breakage of the membrane 470 without providing separate parts or processing.

  In the above embodiment, for the funnel parts, a tapered funnel having a part of straight is used, but is not particularly limited as long as the contents can be appropriately guided to the storage container, for example, You may use the funnel which has a taper shape altogether. Moreover, although the cross-sectional shape of a funnel is circular, you may use the funnel which has a square cross section, for example. The side wall has a cylindrical shape with a circular cross section, but a cylindrical side wall having a square cross section may be used. In addition, it is optional to provide rectangular openings or ribs on the side walls.

  In the above embodiment, an example in which a packaging container (package) is configured using a funnel part including a funnel and a side wall connected to the funnel is shown. However, the side wall is not always necessary, and only the funnel portion described above is used. You may comprise the packaging container (package) which accommodated in the container main body inside. In this case, in order to connect the funnel to the container body, the opening on the wide mouth side of the funnel and the inner surface of the container body may be joined. Further, a funnel may be attached in a state where a ridge is provided on the inner side surface of the container body and the opening on the wide-mouth side is in contact with the ridge.

  Furthermore, in the above embodiment, the dimension of D1 is not necessarily 5 mm or less. For example, if the breaking strength of the membrane is adjusted according to the material of the membrane, the number of cutting lines, and the pattern, D1 is set to 5 mm or more. It is also possible.

  Furthermore, in the above embodiment, the dimension of D2 does not necessarily have to be 3.5 mm or more, and it is possible to obtain a membrane breakage suppressing effect even if it is less than 3.5 mm.

  Furthermore, in the above embodiment, the package is shown in which both the dimensions D1 and D2 are adjusted to obtain both the content wraparound prevention effect and the membrane breakage prevention effect. However, only one of the dimensions is adjusted. You may do it. For example, the side wall end face of the funnel and the open end of the container body may be arranged on the same plane, and the opening on the narrow mouth side of the funnel may protrude from the open end of the container body (that is, D1> 0, and D2 = 0). Alternatively, the opening on the narrow mouth side of the funnel may be arranged on substantially the same plane as the open end of the container body, and the side wall end face of the funnel may be lowered to the bottom side from the open end of the container body (that is, D1≈0, And D2> 0).

  Examples in which the present invention is specifically implemented will be described below.

  The funnel parts were integrally injection molded with a thickness of 0.8 mm using high-density polyethylene.

The sheet forming the side surface of the container main body is provided with a low-density polyethylene (LDPE) layer having a thickness of 20 μm on one side of a paper sheet (paper weighing 300 g / cm ³ ), and an aluminum layer having a thickness of 7 μm is further provided thereon. A polyethylene terephthalate (PET) layer having a thickness of 12 μm is provided on an adhesive, an LDPE layer having a thickness of 50 μm is provided on the adhesive, and an LDPE layer having a thickness of 20 μm is provided on the other surface.

Then, a PET layer having a thickness of 12 μm was provided, an LDPE layer having a thickness of 50 μm was further provided thereon via an adhesive, and an LDPE layer having a thickness of 20 μm was provided on the other surface.

  A cylindrical body having an open end and a bottom surface was formed by a cup molding method using sheets corresponding to the above-described side surface and bottom surface, and a container body was obtained.

  The membrane used was a 12 μm thick PET film provided with an LDPE layer having a thickness of 20 μm on one side, an aluminum layer having a thickness of 15 μm provided thereon, and an LDPE layer having a thickness of 40 μm provided on the other side.

  As the overcap, a high-density polyethylene was integrally injection-molded with a thickness of 0.8 mm.

  Fit the funnel part into the open end of the container body so that the opening on the narrow mouth side of the funnel protrudes 1 mm (D1 in FIG. 9) from the plane including the end surface of the container body, and the side wall outer surface of the funnel part and the container body The inner surface was joined. After filling the inside of the container main body to which the funnel part was attached, the open end of the container main body was sealed with a membrane, and an overcap was attached to cover the membrane to prepare a package.

  When the package was dropped from the height of 60 cm with the open end of the container body facing diagonally downward, the membrane was not broken. In addition, the contents did not go outside the funnel, and the contents did not leak to the outside when the package was opened in refilling.

  The present invention relates to packaging containers and packages for transferring powdered, granular, and liquid fluid materials such as instant coffee and powdered milk, toners for copying machines and laser printers to storage containers, and the like. Can be used for funnel parts.
