The package 1 is filled inside the packaging container 2 and the packaging container 2. Contents 5 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 16 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 refilling of the contents 5 into another 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 refilling the contents 5 in the package 1 into another container 7, 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 container 7. At this time, since the opening of the narrow-mouthed end of the funnel 20 is disposed within the opening of the container 7, to center of the package 2 in the center of the 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 container 7. The opening of the funnel 20 is inserted into the container 7 almost simultaneously with the breaking of the membrane 3. Since the contents 5 in the packaging container 2 are guided into the 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, features of the lid according to the first and second embodiments of the present invention and a package using the lid will be described.

(First embodiment)
8 is a perspective view of a package having a lid according to the first embodiment of the present invention, FIG. 9 is a top view of the package shown in FIG. 8, and FIG. 10 is shown in FIG. it is a sectional view of a ₃ -A ₃ 'line. 11 is a rear view of the lid shown in FIG. 8, and FIG. 12 is a cross-sectional view taken along line B ₃ -B ₃ ′ shown in FIG.

  The lid 304a is for protecting the membrane 303 that seals the open end of the packaging container 302 having the above-described configuration, and is formed by, for example, resin injection molding. Specifically, the lid 304a according to the present embodiment includes a plate-shaped top plate 330, an annular side wall 331 connected to the outer peripheral edge of the top plate 330, and protrusions 337a to 337d protruding from the inner surface of the side wall 331. And a plurality of radial ribs 332a to 332h formed on one surface of the top plate 330, and a plurality of lateral ribs 334a to 334h and 335a to 335h for connecting adjacent ribs.

The top plate 330 has a circular shape corresponding to the open end of the container body 310, and is arranged so that the inner surface thereof faces the membrane 303. Also, as shown in FIG. 10, the vicinity of the outer peripheral edge of the outer surface of the top plate 330 is formed in a step shape, and a step 338a located on the outer peripheral edge and a step 338b located on the inner periphery from the step 338a are provided. ing. The step 338a is for facilitating stacking of the lid 304a before being attached to the package, and the step 338b is for facilitating stacking of the package 301 having the lid 304a attached to the packaging container 302. is there. Further, the top plate 330 is formed with openings 333a and 333b for exhausting air from the space sandwiched between the lid 304a and the membrane 303.

The side wall 331 is formed so as to rise from the outer peripheral edge of the top plate 330 in a direction orthogonal to the top plate 330. The protrusions 337a to 337 provided on the inner surface of the side wall 331 are intermittently arranged in the extending direction of the side wall 331 (that is, the circumferential direction of the top plate 330). In the state where the lid 304 a is attached to the packaging container 302, it is fitted inside the open end partial side wall 331 of the container main body 310 as shown in FIG. 10. More specifically, the protrusions 337a to 337h engage with the flange 312 of the container main body 310 in a state where the flange 312 of the container main body 310 is sandwiched between horizontal ribs 334a to 334h described later, and the container of the lid 304a. The attachment state to the main body 310 is maintained.

  The radial ribs 332 a to 332 h are provided on the inner surface of the top plate 330 and extend radially from the center of the top plate 330 toward the side wall 331 while drawing a gentle arc. The outer ends of the radial ribs 332a to 332h are not connected to the inner surface of the side wall 331 as shown in FIGS.

The lateral rib 334a is provided on the inner surface of the top plate 330 and connects a pair of adjacent radial ribs 332a and 332h. Similarly, the other horizontal ribs 334 b to 334 h connect a pair of corresponding radial ribs. These lateral ribs 334 a to 334 h constitute a first circular rib that is coaxial with the opening 321 on the narrow mouth side of the funnel 320 and has the same diameter. In addition, a plurality of horizontal ribs 335a constituting a second circular rib concentric with a circle formed by the lateral ribs 334a to 334h are connected to the outside of the lateral ribs 334a to 334h. ~ 335h are provided.

  The heights of the radial ribs 332a to 332h, the lateral ribs 334a to 334h, and the 335a to 335h from the inner surface of the top plate 330 are set so that the respective end surfaces (surfaces facing the membrane 303) constitute the same plane. Moreover, the notch 336 as shown in FIG. 12 is formed in each end surface of the horizontal ribs 334a-334h and 335a-335h. The notch 336 functions as an air flow path that connects the sections partitioned by the radial ribs 332a to 332h, the lateral ribs 334a to 334h, and the 335a to 335h.

  Since the package 301 according to the present invention assumes the usage method as described above (FIGS. 6 and 7), the membrane 303 is provided with a cutting line 309 (FIG. 9) for adjusting the breaking strength. Yes. Therefore, if the open end portion of the container body 310 sealed with the membrane 303 is greatly deformed and a tension of a predetermined level or more is applied in the direction intersecting the cutting line 309, the membrane 303 may be broken. Since the lid 304a configured as described above has increased rigidity against bending and twisting by the radial ribs 332a to 332h, the lateral ribs 334a to 334h, and 335a to 335h, the lid 304a is attached to the packaging container 302. Thus, deformation of the open end of the container body 310 can be suppressed. Therefore, according to the lid 304a according to the present embodiment, in addition to preventing direct damage to the membrane 303 by covering the surface, it is possible to prevent unexpected breakage due to deformation of the container body 310.

  When the lid 304a is attached to the packaging container 302, as shown in FIG. 10, the membrane 303 is composed of radial ribs 332a to 332h, lateral ribs 334a to 334h, and 335a to 335h. In contact with the surface to be done. Therefore, even when a pressing force is applied to the top plate 330 of the lid 304a, the pressing force can be dispersed and transmitted to the membrane 303, and the membrane 303 can be prevented from being broken due to the concentration of the pressing force in a part.

  In particular, in the lid 304a according to the present embodiment, the lateral ribs 334a to 334h constitute a circle having the same diameter and the same diameter as the opening 321 on the narrow mouth side of the funnel 320, as shown in FIG. The end faces of the lateral ribs 334 a to 334 h abut against the opening 321 of the funnel 320 through the membrane 303. When a pressing force is applied to the top plate 330, it is relatively easy to bend toward the center side. However, in addition to being suppressed by the radial ribs 332a to 332h, the funnel 320 welded to the container body 310 is used for the top. Since the bending of the plate 330 is prevented, the breakage of the central portion of the membrane 303 is further effectively prevented. In addition, by sandwiching the membrane 303 between the lateral ribs 334 a to 334 h and the opening 321, it is possible to suppress the contents of the packaging container 302 from flowing to the outer surface side of the funnel 320 through the opening 321.

As shown in FIG. 9, since the radial ribs 332a to 332h are curved, the linear cutting line 309 provided on the membrane 303 and the radial ribs 332a to 332h do not completely overlap with each other. The number of intersections is minimized. Therefore, the membrane 303 is prevented from being broken due to the pressing force applied from the radial ribs 332 a to 332 h to the cutting line 309 having a relatively low strength. In particular, in this embodiment, the number of cutting lines 309 formed on the membrane 303 is different from the number of radial ribs 332a to 332h. With this configuration, the cutting line 309 of the membrane 303 and the radial ribs 332a to 332h can be prevented from matching with each other, so that the cutting line 309 is accidentally broken when an impact is applied to the lid 304a. Can be more effectively prevented.

  Furthermore, since the outer end portions of the radial ribs 332a to 332h and the inner surface of the side wall 331 are cut, the side wall 331 is allowed to bend to some extent. With this configuration, even when a large impact is applied to the side wall 331 when the package 301 attached with the lid 304a is dropped, only the side wall 331 is bent to mitigate the impact instead of the top plate 330 being deformed together with the side wall 331. can do. Therefore, the membrane 303 is prevented from being broken when the package 301 is dropped. In this embodiment, as shown in FIGS. 8 and 11, since the protrusions 337a to 337d that engage with the flange 312 are intermittently disposed, the portion of the side wall 331 where the protrusion is not provided is free to bend. The degree of breakage is large, and the effect of preventing breakage when dropped is further improved.

  In the lid body 304a according to the present embodiment, openings 333a and 333b are provided on the top plate 330, and notches 336 are provided on the end surfaces of the lateral ribs 334a to 334h and 335a to 335h, thereby forming the inner surface of the top plate 330. An air escape path is secured between the compartments and between the inside and outside of the lid 304a. When there is no such vent, there is a possibility that the membrane 303 may be broken by the air compressed between the lid and the membrane 303 when a pressing force or impact is applied to the lid. In the lid 304a according to the present embodiment, since there is a vent hole, there is no such concern.

  In addition to the above-described rupture prevention effect after attachment, the lid 304a according to the present embodiment can also prevent the membrane 303 from rupturing when the lid 304a is attached to the packaging container 302, as described below.

  When the lid 304 a is attached to the packaging container 302, the flange 312 of the container main body 310 is fitted into the side wall 331 while the side wall 331 is expanded. In this process, the air sandwiched between the lid 304a and the membrane 303 is discharged to the outside through the gaps formed between the openings 333a and 333b of the top plate 330 and the protrusions 337a to 337d on the inner surface of the side wall 331. . Therefore, when the lid 304a is attached, there is no possibility that air is compressed between the lid 304a and the membrane 303 and the membrane 303 is broken.

  In addition, by separating the outer ends of the radial ribs 332a to 332h and the inner surfaces of the side walls 331, the side walls 331 can be easily expanded when the flange 312 is fitted, so that deformation of the fitted container body 310 is reduced. . Therefore, it is possible to prevent the container body 310 from being deformed and breaking the membrane 303 when the lid 304a is attached.

  Further, since the projections 337a to 337d that engage with the flange 312 are provided partially rather than the entire circumference of the side wall 331, the force required to fit the lid 304a can be reduced, and this also causes deformation and deformation of the container body 310. Breakage of the membrane 303 due to this can be prevented.

  As described above, according to the present embodiment, it is possible to realize the lid 304 a that can stably protect the membrane both during and after the manufacture of the package 301. Moreover, since the lid 304a according to the present embodiment can be molded with a minimum amount of resin, it is excellent in terms of resource saving.

(Second Embodiment)
FIG. 13 is a perspective view of a package having a lid according to the second embodiment of the present invention, and FIG. 14 is a sectional view taken along line C ₃ -C ₃ ′ shown in FIG.

  Since the basic configuration of the lid 304b according to the present embodiment is the same as the lid 304a according to the first embodiment, the following description will focus on the differences between the present embodiment and the first embodiment. To do.

  In the present embodiment, a plurality of slits 339 are formed in the side wall 331. Further, a protrusion 340 is provided on the inner surface of the side wall 331 over the entire circumference of the side wall 331 except for a portion where the slit 339 is formed.

  By providing the slit 339 in this manner, the degree of freedom of deformation of the side wall 331 is improved, so that the side wall 331 can be bent and the impact can be reduced when the package 301 is dropped. Thereby, the deformation | transformation of the container main body 310 and the fracture | rupture of the membrane 303 resulting from this can be suppressed.

  Moreover, since the force required to fit the lid 304a can be reduced by the slit 339, the deformation of the container body 310 and the breakage of the membrane 303 due to this can be prevented when the lid 304a is attached.

(Other variations)
In each of the first and second embodiments described above, a horizontal rib is provided on the inner surface of the top plate. However, depending on the material, strength, and dimensions of the top plate and membrane, a lid that does not include the horizontal rib may be provided. It may be configured.

  Further, in each of the above-described embodiments, the plurality of lateral ribs constitute a circle having the same diameter and the same diameter as the opening on the narrow mouth side of the funnel. May be arranged discontinuously or may form a polygon. Further, the number of the lateral ribs is not particularly limited, and can be arbitrarily set according to the required strength of the lid.

  Further, in each of the above embodiments, a notch may be formed on the end surface of the radial rib in addition to the notch provided on the end surface of the lateral rib. Or you may provide a notch only in the end surface of a radial rib instead of providing a notch in the end surface of a horizontal rib.

  Further, in each of the above embodiments, instead of forming a notch in the end face of the lateral rib, an opening may be provided in the top plate of the section closed by the radial rib and the lateral rib.

  Furthermore, in each of the above-described embodiments, the example has been described in which the radial ribs are formed in an arc shape and the cutting line of the membrane is formed in a linear shape, but the shapes of the radial ribs and the cutting line are not particularly limited. However, as described above, it is preferable that the radial ribs and the cutting lines have shapes that do not coincide with each other in terms of preventing the membrane from breaking.

  Furthermore, the slit shown in the second embodiment may be formed on the side wall of the lid according to the first embodiment. Or you may provide the protrusion of the side wall inner surface of the cover which concerns on said 2nd Embodiment intermittently in the circumferential direction like 1st Embodiment.
