Description

  The present invention relates to a packaging container for packaging powdery or liquid material and transferring contents to another container.

  Powdered (powdered or granular) foods such as instant coffee are generally sold in a sealed container such as a capped bottle in order to maintain airtightness after opening. In addition, a packaging container in which contents are simply packaged for the purpose of reusing the sealed container after the contents are consumed and refilling only the contents is also known. As a packaging container, a pouch, a gusset bag, a cylindrical container with an opening sealed, and the like are widely used.

  When refilling the contents from these packaging containers to other containers, the packaging containers are opened and addressed to the openings of the other containers, and the contents are gradually transferred. At this time, the contents may spill and dirty hands and surroundings, and the transfer work is complicated.

  In order to solve this problem, Patent Document 1 proposes a packaging container capable of transferring contents more easily.

  11 is a perspective view of a conventional packaging container described in Patent Document 1, and FIG. 12 is a cross-sectional view taken along the line XII-XII shown in FIG.

  The packaging container 110 is for containing the contents 108, and the cylindrical container body 101 in which the funnel part 102 including the funnel 103 and the side wall 106 is attached to the open end of the container body 101 is sealed with a seal lid 107. Furthermore, an overcap 120 for protecting the seal lid 107 during the distribution process is attached so as to cover the entire surface of the seal lid 107.

  However, in the packaging container 110 of Patent Document 1, the contents 108 may wrap around from the inside to the outside of the funnel 103. Here, an overcap described in Patent Document 2 has been proposed in order to reliably prevent the contents 108 from wrapping around.

  A plurality of ribs are provided on the inner surface of the overcap described in Patent Document 2, and when the overcap is fitted into the open end of the container body, these ribs press the seal lid from the outside, Adhesion between the entire peripheral edge of the narrow-side opening of the funnel and the inner surface of the seal lid is enhanced. This protects the seal lid and reliably prevents the contents from wrapping around from the inside to the outside of the funnel.

(First embodiment)
FIG. 1 is a perspective view of the packaging container according to the first embodiment, and FIG. 2 is a cross-sectional view taken along line II-II of the packaging container shown in FIG.

  A packaging container 11 according to the first embodiment includes a container body 1, a funnel part 2 fitted into the open end of the container body 1, a seal lid 7 that seals the open end of the container body, a plate member 21, and a seal. And a lid body 31 that covers the lid 7.

  The container body 1 is formed of a bottom surface and a cylindrical side wall having an open end, and a flange portion that extends outward is connected to the open end. The container body 1 is made of a material mainly made of paper.

  The funnel part 2 is used to guide the contents 8 to another container. The funnel 3 has a diameter that narrows from the wide opening 4 toward the narrow opening 5 and a cylindrical side wall connected to the funnel 3. 6. The funnel part 2 has the narrow mouth side opening 5 facing the open end of the container body 1, and the peripheral portion of the narrow mouth side opening 5 is at the same level as the plane portion including the side wall end surface constituting the open end of the container body 1 or It is attached to the inside of the container main body 1 so as to protrude from the flat portion. This funnel part 2 is formed by integral molding using resin, for example.

  The seal lid 7 is made of a circular sheet and seals the open end by welding to the flange of the container body 1. The seal lid 7 is formed with a break line (not shown) including perforations so that the seal lid 7 is broken when a constant pressing force is applied from the outside.

  The plate member 21 is formed in a circular shape using a material mainly made of paper, and is disposed on the seal lid 7 at a position corresponding to the narrow-side opening 5 of the funnel 3. In the present embodiment, the plate material 21 functions as a pressing member.

  The lid 31 functions as a holding member that protects the seal lid 7 and holds the plate material 21. The lid 31 is made of a paper-based material, and includes a top plate 41 that covers the entire surface of the seal lid 7 and a cylindrical side wall 51 that extends vertically from the outer periphery of the top plate 41 downward in FIG. . The plate material 21 is attached to the central portion of the inner surface of the lid 31 (the lower surface of the top plate 41 in FIG. 2).

  When the inner surface of the top plate 41 is opposed to the seal lid 7 and the lid body 31 is fitted to the open end of the container body 1, the flange of the container body 1 is fitted to the side wall 51 and the lid body 31 is fixed to the container body 1. Is done. At this time, the plate 21 is pushed inward of the container body 1 at a position corresponding to the narrow opening 5 of the funnel 3, and the inner surface of the seal lid 7 and the entire peripheral edge of the narrow opening 5 are Is kept in close contact.

  In this way, in the packaging container 11, the inner surface of the seal lid 7 and the entire peripheral edge of the narrow opening 5 of the funnel 3 are in close contact with each other. Can be prevented. In the packaging container 11, the plate material 21 arranged at a position corresponding to the narrow opening 5 is pushed inward of the container body 1. For example, a ring-shaped inner diameter larger than the peripheral edge of the narrow opening 5 is used. Even if the plate material 21 is pushed inward of the container main body 1 at a position corresponding to the outside of the narrow opening 5, the inner surface of the seal lid 7 and the entire peripheral edge of the narrow opening 5 can be brought into close contact with each other. . However, from the viewpoint of preventing the contents 8 from wrapping around from the inner side to the outer side of the narrow opening 5, it is more effective to dispose the pressing member at a position corresponding to the inner side of the narrow opening 5. The entire periphery of the narrow opening 5 can be more reliably adhered.

  Here, in order to bring the inner surface of the seal lid 7 into close contact with the entire peripheral edge of the narrow opening 5 and prevent the contents 8 from wrapping around from the inside to the outside of the funnel 2, The thickness may be 1 to 10 mm, preferably 2 to 5 mm. When the thickness of the pressing member is less than 1 mm, when the lid body 31 is attached to the container body 1, the adhesiveness between the inner surface of the seal lid 7 and the entire peripheral edge of the narrow opening 5 is insufficient, and the inside of the funnel 3 There is a possibility that the contents wrap around from the outside to the outside. On the other hand, if the thickness of the pressing member exceeds 10 mm, the seal lid 7 may be broken.

  Further, in this embodiment, the member that prevents the contents 8 from wrapping around can be produced simply by sticking the circular plate material 21 to the inner surface of the lid 31, and is simpler than a conventionally used overcap. Because of its structure, it can be made of a paper-based material. In addition to the configuration of the packaging container 11, as described in JP 2009-280283 A, when a protective sheet is detachably attached to the outer surface of the seal lid 7 (upper side in FIG. 2), the seal This is effective in preventing unintended breakage of the lid 7. The lid 31 may be made by cup molding using a circular sheet to be the top plate 41 and a rectangular sheet to be the side wall 51, or a ring-shaped sheet having stretchability is drawn. You may use what you did.
