Description

  The present invention relates to a packaging container for packaging a substance having fluidity such as powder, granule, and liquid, and transferring the contents to a storage container, and a funnel part used therefor.

  In general, powdered food products such as instant coffee are sold in a state of being filled in a highly sealed packaging container such as a bottle with a cap so that the hermeticity during storage can be maintained. In addition, for the purpose of refilling the contents and reusing the storage container, a packaging container for refilling in which the contents are simply packaged is also known. As a packaging container used as such a refilling package, for example, a pouch, a gusset bag, or a cup-shaped container is used.

  When refilling the contents from these packaging containers into the storage container, the packaging container is opened, directed to the opening of the storage container, and the contents are gradually refilled. At this time, the contents may spill out and soil the hands and surroundings, and the refilling operation is complicated. In order to solve this problem, Patent Document 1 proposes a refill package that allows the contents to be refilled more easily. The package described in Patent Document 1 is configured by fitting a hopper inside a cylindrical container, filling the container with contents, and sealing the opening of the container with a pierceable cover. By applying the rupture to the opening of the refill container, the contents can be easily refilled via the hopper.

  However, in the package described in Patent Document 1, the contents may wrap around the outside of the hopper discharge port through the gap between the hopper discharge port and the pierceable cover. In Patent Document 2, the wraparound of the content is prevented. A packaging container is disclosed.

  FIG. 11 is a longitudinal sectional view of a conventional packaging container 900 disclosed in Patent Document 2. As shown in FIG.

  The packaging container 900 includes a cylindrical container body 920, a funnel part 930, a seal lid 960, and an overcap 980. The funnel part 930 includes a funnel 931 and a side wall 932 connected to the wide-mouth end of the funnel 931. The side wall 932 is fitted inside the container main body 920 and joined to the inner surface of the container main body 920. The funnel 931 has a shape whose diameter narrows toward the outside of the opening of the container body 920. Further, the narrow edge side edge of the funnel 931 and the open edge of the container body 920 constitute the same plane. The container body 920 is filled with the contents 950 and the edge of the open end of the container body 920 is sealed with a seal lid 960. Furthermore, an overcap 980 that covers the top of the seal lid 960 is attached to prevent the seal lid 960 from being broken during storage or distribution.

  The inner surface of the overcap 980 is provided with a circular rib 981 that faces the narrow opening of the funnel 931. The seal lid 960 is sandwiched between the rib 981 and the narrow side edge of the funnel 931 with the overcap 980 attached to the container body 920, and the seal lid 960 and the narrow side of the funnel 931. It is possible to prevent a gap from being formed between the end edge 934 and the end edge 934. Accordingly, the phenomenon (powder around) in which the contents 950 pass between the seal lid 960 and the narrow edge 934 of the funnel 931 and moves to the outside of the funnel 931 is prevented.

  However, providing such an overcap 980 in the packaging container 900 has a large load in terms of manufacturing cost, resources, and environment. Therefore, it is preferable to eliminate the overcap 980.

  Therefore, an object of the present invention is to provide a packaging container in which the contact between the sealing lid and the funnel is maintained even if there is no overcap, and powder is prevented.

(First embodiment)
A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a perspective view of a packaging container 100 according to the present embodiment. 2 is a cross-sectional view taken along line AA ′ shown in FIG. The packaging container 100 includes a cylindrical container body 120, a funnel part 130, and a seal lid 160. The funnel part 130 includes a funnel 131 and a side wall 132 that is connected to the wide-mouth end of the funnel 131 and surrounds the outer surface of the funnel 131. The side wall 132 is fitted into the container body 120 and joined to the inner surface of the container body 120. The funnel 131 has a shape whose diameter narrows toward the outside of the opening of the container body 120. The container body 120 is filled with a content 150 such as powder, and the opening of the container body 120 is sealed with a seal lid 160. The seal lid 160 is provided with radial cutting lines 199 from the center in order to facilitate breakage when pressed at the time of refilling.

  Examples of the material of the container body 120 include materials having a layer structure of LDPE (low density polyethylene) / paper / LDPE / aluminum / adhesive / PET (polyethylene terephthalate) / adhesive / LDPE in order from the outer surface. Moreover, HDPE (high density polyethylene) is mentioned as a material of the funnel part 130. Further, as a material of the seal lid 160, a material having a layer configuration of aluminum / LDPE / PET / LDPE in order from the outer surface can be given.

  The funnel 131 is connected to a tapered portion 1311 whose diameter narrows from the wide mouth side toward the narrow mouth side, a straight portion 1312 whose one end is connected to the narrow mouth side edge of the tapered portion 1311, and the other end of the straight portion 1312. And a flap portion 1313 whose diameter narrows toward the narrow mouth side of the funnel 131. The flap part 1313 has flexibility, and when the flap part 1313 opens and closes, the end edge 134 can move within a certain range in the axial direction of the container body 120.

  An end edge 134 on the narrow mouth side of the funnel 131 protrudes outward from a plane including the open end of the container body 120. The seal lid 160 is sealed to the container body 120 in a state where the flap portion 1313 is pushed inward of the container body 120. When the internal pressure of the container main body 120 increases or the external air pressure decreases and the seal lid 160 swells outward from the container main body 120, the flap 1313 is repelled by being pushed in at the time of sealing. The end edge 134 on the narrow mouth side of the funnel 131 moves outward along the axial direction of the container main body 120 by being deformed so as to spread outward of the main body 120. Further, when the internal pressure of the container body 120 is lowered or the external air pressure is increased and the seal lid 160 is recessed inward of the container body, the flap portion 1313 is deformed so as to be further closed inside. The narrow end 134 of the funnel 131 moves inward along the axial direction of the container body 120. As a result, the end 134 of the funnel 131 on the narrow mouth side can be kept in contact with the seal lid 160 and can prevent powdering.

  As a preferred example of this embodiment, the length d1 of the flap portion 1313 (the length from the connecting portion to the straight portion 1312 to the upper edge) is 3 mm, the wall thickness d2 is 0.5 mm, and the axial direction of the container body 120 The inclination angle θ with respect to the angle is 45 °. In this example, the protruding amount d3 of the narrow end 134 of the funnel 131 from the plane including the open end of the container body 120 is 3 mm when the container body 120 is not sealed with the seal lid 160. In a state where the container main body 120 is sealed with the lid 160, the thickness is 1 mm. The length of the flap portion 1313 from the connection portion with the straight portion 1312 to the upper end edge and the inclination angle only need to ensure a diameter through which the contents 150 can pass. In addition, as the inclination angle is larger, the contact area between the seal lid 160 and the flap portion 1313 is increased, and the effect of preventing powder rotation is higher.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIG. The appearance of the packaging container 200 according to the present embodiment is the same as that of the packaging container 100 according to the first embodiment, and illustration thereof is omitted. Moreover, about the location similar to the packaging container 100, the same referential mark is attached | subjected and description is abbreviate | omitted. In FIG. 3, the longitudinal cross-sectional view of the packaging container 200 is shown.

  The funnel 231 which is a constituent element of the funnel part 230 includes a tapered portion 2311 whose diameter narrows from the wide mouth side toward the narrow mouth side, a straight portion 2312 whose one end is connected to the narrow mouth side edge of the tapered portion 2311, It consists of a curved bent portion 2313 that connects the wide-mouthed portion of the tapered portion 2311 and the side wall 132. In the present embodiment, the bent portion 2313 has a cross-sectional shape drawn by an arc having a radius of curvature greater than or equal to a predetermined radius, but may have a continuously bent shape other than the arc. The bent portion 2313 can be bent and bent. Thereby, the narrow edge 234 of the funnel 231 can move within a certain range in the axial direction of the container body 120. An end edge 234 on the narrow mouth side of the funnel 231 protrudes outward from a plane including the open end of the container body 120. The seal lid 160 is sealed to the container body 120 in a state where the funnel 231 is pushed inward of the container body 120.

  Thus, as in the first embodiment, when the seal lid 160 swells outward or inward of the container main body 120, the end 234 on the narrow mouth side of the funnel 231 moves following this, and the seal lid 160 The state in contact with the lid 160 can be maintained.

  As a preferred example of this embodiment, the radius of curvature R1 of the bent portion 2313 is 3 mm to 5 mm, and the thickness d4 of the bent portion 2313 is 0.2 mm or more. If the locality radius is smaller than this, it is difficult to obtain flexibility, and if it is larger than this, the restoring force from the bent state becomes weak, and it becomes difficult to obtain the effect of preventing powder rotation. On the other hand, if the thickness is smaller than this, it becomes difficult to obtain the flexibility of the bent portion 2313.

(Third embodiment)
Hereinafter, a third embodiment of the present invention will be described with reference to FIG. The appearance of the packaging container 300 according to the present embodiment is the same as that of the packaging container 100 according to the first embodiment, and illustration thereof is omitted. Moreover, about the location similar to the packaging container 100, the same referential mark is attached | subjected and description is abbreviate | omitted. In FIG. 4, the longitudinal cross-sectional view of the packaging container 300 along the plane which passes along the axis | shaft of the container main body 120 is shown.

  The funnel 331, which is a constituent element of the funnel part 330, has a portion having a shape of a broken line whose diameter is narrowed from the wide mouth side toward the narrow mouth side and is bent at the bending points 3313 and 3314 in the longitudinal section, and the narrow mouth side end of this portion It consists of a straight part 3312 connected to the edge. This bending point is distributed over the entire circumference of the funnel 331 to form a bent portion. In the longitudinal section of the funnel 331, the angle between the end of the wide mouth side and the bending point 3313 and the axial direction of the container body 120 is defined as θ2. Further, in the longitudinal section of the funnel 331, an angle formed by the portion from the bending point 3313 to the bending point 3314 with the axial direction of the container body 120 is defined as θ3. Further, in the longitudinal section of the funnel 331, an angle formed by a portion from the bending point 3314 to the connecting portion with the straight portion 3312 with the axial direction of the container body 120 is defined as θ4. In this embodiment, θ2> θ3 and θ4> θ3, and the vicinity of the bent portion formed by the bending point 3313 is convex toward the inside of the funnel 331, and the vicinity of the bent portion formed by the bending point 3314 is The convex shape is formed toward the outside of the funnel 331. Alternatively, for example, θ3> θ2 and θ3> θ4, and the direction of the convex shape described above may be reversed. Such a convex portion absorbs these forces by changing its shape when subjected to a compressive force or a tensile force, and therefore has a greater stress strain than a flat portion. Therefore, the funnel 331 has such a convex portion, and thus has a larger elasticity than the case where the convex portion is not provided, and can be bent. Thereby, the narrow edge side edge 334 of the funnel 331 can move within a certain range in the axial direction of the container body 120. An end edge 334 on the narrow mouth side of the funnel 331 protrudes outward from a plane including the open end of the container body 120. The seal lid 160 is sealed to the container body 120 in a state where the funnel 331 is pushed inward of the container body 120.

  As a result, as in the first embodiment, when the seal lid 160 bulges outward from the container main body 120 or indents inward, the end 334 on the narrow mouth side of the funnel 331 follows this. The state which moved and contacted the seal lid | cover 160 can be maintained.

  In the present embodiment, two bent portions are provided, but may be one or three or more. Further, the angle formed by the broken line of the longitudinal section of the funnel 331 and the axial direction of the container main body 120 is more easily bent as the amount of change at each bending point is larger. However, if a convex portion having a large protruding amount toward the outside of the funnel 331 is formed, the contents 150 are likely to remain on the convex portion at the time of refilling. Therefore, the amount of change only needs to be increased to such an extent that no large convex portion is formed so that the contents 150 remain. The funnel 331 may be easily bent by making the thickness of the vicinity of the bent portion thinner than other portions.

(Fourth embodiment)
A fourth embodiment of the present invention will be described below with reference to FIG. The appearance of the packaging container 400 according to the present embodiment is the same as that of the packaging container 100 according to the first embodiment, and illustration thereof is omitted. Moreover, about the location similar to the packaging container 100, the same referential mark is attached | subjected and description is abbreviate | omitted. In FIG. 5, the longitudinal cross-sectional view of the packaging container 400 along the plane which passes along the axis | shaft of the container main body 120 is shown.

  The funnel 431, which is a constituent element of the funnel part 430, has a portion that has a curved shape with an inflection point 4313 in the longitudinal section, and a narrow edge on the narrow mouth side. And a straight portion 4312 connected to the. The inflection points are distributed over the entire circumference of the funnel 431 to form an inflection portion. In the funnel 431 of this embodiment, the end from the wide-mouth side to the inflection point 4313 has a convex shape toward the outside, and the connection from the inflection point 4313 to the straight portion 5312 faces inward. And has a convex shape. Alternatively, the end from the wide-mouth side edge to the inflection point 4313 may be convex toward the inside, and the connection from the inflection point 4313 to the straight portion 4312 may be convex toward the outside. The funnel 431 can bend like the funnel 331 of 3rd Embodiment by providing a convex-shaped part. As a result, the narrow edge 434 of the funnel 431 can move within a certain range in the axial direction of the container body 120. An end edge 434 on the narrow mouth side of the funnel 531 protrudes outward from a plane including the open end of the container body 120. The seal lid 160 is sealed to the container body 120 in a state where the funnel 431 is pushed inward of the container body 120.

  Thus, as in the first embodiment, when the seal lid 160 bulges outward or inwardly from the container body 120, the narrow edge 434 of the funnel 431 follows this. The state which moved and contacted the seal lid | cover 160 can be maintained.

  As a suitable example of the present embodiment, there may be mentioned one in which the protruding amount d5 of the end 434 on the narrow mouth side of the funnel 431 from the plane including the open end of the container body 120 is 3 mm. In this example, when the force of 200 N is applied to the narrow edge side edge 434 of the funnel 431 in the inward direction of the container main body 120, the movement amount of the edge 434 is 3 mm or more.

In FIG. 6, the longitudinal cross-sectional view of the packaging container 500 along the plane which passes along the axis | shaft of the container main body 120 is shown.

  The funnel 531 which is a component of the funnel part 530 includes a tapered portion 5311 whose diameter narrows from the wide-mouth side toward the narrow-mouth side, and a straight portion 5312 whose one end is connected to the narrow-mouth side edge of the tapered portion 5311. Become. The tapered portion 5311 is provided with a thin portion 5313 formed by forming a groove so as to go around the inner peripheral surface. The funnel 531 can be bent at the thin portion 5313. Thereby, the narrow side edge of the funnel 531 can be moved within a certain range in the axial direction of the container body 120. An end edge 534 on the narrow mouth side of the funnel 531 protrudes outward from a plane including the open end of the container body 120. The seal lid 160 is sealed to the container main body 120 in a state where the funnel 531 is pushed inward of the container main body 120.

  As a result, as in the first embodiment, when the seal lid 160 bulges outward or inwardly from the container body 120, the narrow edge 534 of the funnel 531 follows this. And can maintain the state in contact with the seal lid 160.

  As a suitable example of this embodiment, the thickness d6 of the thin portion 5313 of the funnel 531 is 0.3 mm, the thickness d7 of the portion other than the thin portion 5313 is 0.7 mm, and the plane including the open end of the container body 120 is used. In this case, the amount of protrusion d8 of the upper end edge 534 of the funnel 531 is 3 mm. In this example, when the force of 200 N is applied to the narrow edge side edge 534 of the funnel 531 in the inward direction of the container main body 120, the moving amount of the edge 534 is 3 mm or more.

  Moreover, in this embodiment, although the thin part 4313 was provided in the inner peripheral surface of the funnel 531, you may provide in an outer peripheral surface.

(Sixth embodiment)
A packaging container 600 according to a sixth embodiment of the present invention will be described with reference to FIG. The appearance of the packaging container 600 is the same as that of the packaging container 100 according to the first embodiment, and illustration thereof is omitted. Moreover, about the location similar to the packaging container 100, the same referential mark is attached | subjected and description is abbreviate | omitted. In FIG. 7, the longitudinal cross-sectional view of the packaging container 600 along the plane which passes along the axis | shaft of the container main body 120 is shown.

  The funnel 631 that is a constituent element of the funnel part 630 is different from the funnel 531 of the fifth embodiment in the position where the thin portion is provided, and is provided with a thin portion at the connecting portion between the funnel 631 and the side wall 132. The funnel 631 includes a tapered portion 6311 whose diameter narrows from the wide mouth side toward the narrow mouth side, and a straight portion 6312 whose one end is connected to the narrow mouth side edge of the tapered portion 6311. The thin portion 6313 is formed by reducing the thickness of the inner peripheral side of the wide-edge end edge of the tapered portion 6311 and reducing the thickness of the connecting portion of the side wall 632 with the tapered portion 6311. The tapered portion 6311 can be bent at the thin portion 6313. Thereby, the narrow edge side edge of the funnel 631 can move within a certain range in the axial direction of the container body 120. An end edge on the narrow mouth side of the funnel 631 projects outward from a plane including the open end of the container body 120. The seal lid 160 is sealed to the container body 120 in a state where the funnel 631 is pushed inward of the container body 120.

  Thus, as in the first embodiment, when the seal lid 160 swells outward or inward of the container body 120, the narrow edge 634 of the funnel 631 moves following the seal lid 160 to move the seal The state in contact with the lid 160 can be maintained.

(Seventh embodiment)
Hereinafter, a seventh embodiment of the present invention will be described with reference to FIG. The appearance of the packaging container 700 according to the present embodiment is the same as that of the packaging container 100 according to the first embodiment, and illustration thereof is omitted. Moreover, about the location similar to the packaging container 100, the same referential mark is attached | subjected and description is abbreviate | omitted. In FIG. 7, the longitudinal cross-sectional view of the packaging container 700 along the plane which passes along the axis | shaft of the container main body 120 is shown.

  The funnel part 730 is obtained by replacing the side wall 132 with the side wall 732 in the funnel part 130 of the packaging container 100 of the first embodiment. FIG. 9 shows an enlarged view of a portion including the upper edge of the side wall 732 and the flange portion 1201 of the opening of the container body 120 (a portion surrounded by a broken line in FIG. 8). The flange portion 1201 is formed by folding the side wall portion of the container main body 120 outward and overlapping, and sealing the overlapping portion. Therefore, the inner peripheral part of the flange part 1201 is rounded.

  The side wall 732 is welded to the container body 120 after being fitted into the container body 120. The side wall 732 includes a flange portion 7321 at the upper end edge. When the side wall 732 is fitted into the container main body 120, the flange portion 6321 of the side wall 732 is hooked on the rounded portion of the inner periphery of the flange portion 1201 of the container main body 120, so that the side wall 732 passes through the fitting position and the container main body 120. Is prevented from shifting inwardly. After the fitting process, when sealing the seal lid 160 to the flange portion 1201 of the container main body 120, the material of the flange portion 7321 of the side wall 732 melts and covers the rounded portion of the inner periphery of the flange portion 1201, so the flange portion of the side wall 732 7321 and the flange portion of the edge 1201 constitute the same plane. In this embodiment, although the side wall 132 of the packaging container 100 which concerns on 1st Embodiment was substituted by the side wall 732, you may replace the side wall of the packaging container of other embodiment.

  As described above, in each embodiment of the present invention, when the seal lid swells outward from the container body, the contact between the seal lid and the funnel is maintained even if there is no overcap to prevent powder around. Can do. In addition, when the seal lid is recessed inward of the container body, the funnel can move inward while maintaining the state where the seal lid and the funnel are in contact with each other, so the pressure at the contact point between the seal lid and the funnel is relieved. The seal lid can be prevented from being carelessly broken.

  Moreover, in each embodiment, the protrusion amount of the upper end edge of the funnel from the plane including the open end of the container body is 5 mm or less, so that the force that the seal lid receives from the funnel can be kept below a certain amount. The seal lid can be prevented from being carelessly broken.

  In these embodiments, the seal lid seals the container body in a state where the funnel is pushed inwardly toward the inside of the container body, but the narrow end side edge of the funnel is not pushed into the funnel. It is good also as what seals a container main body in the state which a seal lid contacted. In this case, when the external pressure is higher than the internal pressure of the container main body, when the seal lid is recessed inward of the container main body, the end of the narrow side of the funnel moves following this to relieve the external pressure, It is possible to prevent the seal lid from being broken.

  Moreover, in the packaging container of this invention, the overcap which protects a seal lid becomes unnecessary. In this case, it is preferable to improve the strength of the seal lid itself by using a seal lid having a peelable protective film layer. A seal lid with improved strength is disclosed in Japanese Patent Application Laid-Open No. 2009-280283. In a packaging container using such a seal lid, the protective film is peeled off at the time of refilling, and then the storage container is refilled. The use of a material having a protective film layer for the sealing lid is less expensive in terms of production cost, resources and environment than using an overcap. Examples of the material of the seal lid having such a protective film layer include materials having a layer configuration of PET / peeling layer / aluminum / LDPE / PET / LDPE in order from the outside. Furthermore, the packaging container may be packaged with a shrink film to ensure virginity during storage or distribution.

  Each of the above-described embodiments is merely an example and does not limit the present invention. In particular, the shape of the funnel is not limited as long as the end on the narrow mouth side can be bent so as to be movable in the axial direction of the container body, and can be realized in various ways.

(Eighth embodiment)
Hereinafter, an eighth embodiment of the present invention will be described with reference to FIG. FIG. 10 is a longitudinal sectional view of the packaging container 800 along a plane passing through the axis of the container body 120. The packaging container 800 is the same as the packaging container 100 according to the first embodiment except that the flap portion 1313 is removed and the straight portion 1312 is replaced with a straight portion 8312 so that the funnel 831 does not move in the axial direction of the container body. It has become. The protruding amount of the end 834 on the narrow mouth side of the funnel 831 (the protruding amount outward from the plane including the open end of the container body 120) d12 is set to 7-15 mm. By setting the protruding amount of the funnel 831 to such a value, the contact between the seal lid 160 and the funnel 131 can be easily maintained without the overcap. However, since the force that the seal lid 160 receives from the contact point with the funnel 131 increases, a configuration in which a protective film as disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2009-280283 is provided as the seal lid 160 is adopted. It is desirable to do.
