Description

  The present invention relates to a resealable container after opening.

  Containers containing food materials are required to be sealed to prevent the food materials from being tampered with or deteriorated. In addition, if it is assumed that the food cannot be eaten in one meal, or if it is assumed that the food is consumed little by little, such as boiled or pickled, it is required to be able to reseal after opening. .

  As described above, a container that requires sealing and resealability generally includes three parts, that is, a container body, a sealing lid member, and a resealing lid. The container main body has a housing portion for containing the foodstuff, and a flange portion connected to the opening periphery of the housing portion. The seal lid material is in the form of a film or a sheet and is thermally welded to the flange portion. The internal space of the housing portion is sealed by this heat welding. The reseal lid is detachably placed on the flange portion.

  When taking out foodstuff from the said container, a reseal lid is removed from a flange part and a seal lid material is peeled from a flange part. The seal lid material cannot be resealed after being peeled off from the flange portion, but can be resealed by covering the flange portion with the reseal lid again.

The container requires a sealing lid material for sealing and a reseal lid in addition to the container main body, and thus the manufacturing cost increases.
FIG. 10 of Patent Document 1 discloses a container composed of a container main body and a seal lid material thermally welded to a flange portion of the container main body. In the flange portion, a planned cutting line that can be cut by an external force is formed by drawing an annular line. The opening peripheral edge of the housing part and the outer peripheral edge of the flange part form a quadrangle, and the line to be cut also forms a quadrangle along the opening peripheral part and the outer peripheral edge. The flange portion has a bulging portion protruding downward at the center of the four sides of the line to be cut.

In the container of Patent Document 1, the internal space of the housing portion is sealed by thermal welding of the seal lid member and the flange portion. At the time of opening, the flange portion is cut along the planned cutting line by pinching the region outside the planned cutting line of the flange portion and the seal lid with a finger and bending it upward. Thereby, it isolate | separates into the container main body which consists of an accommodating part and the inner area | region (area | region inside a cutting scheduled line) of a flange part, and the reseal lid | cover which consists of a sealing lid material and the outer area | region of a flange part.
The bulging portion is separated into an inner portion and an outer portion by cutting along the planned cutting line.

At the time of resealing, the reseal lid is placed on the inner area of the flange portion of the container body. At this time, the closed state of the reseal lid is held by the hook between the edge of the inner portion of the bulging portion belonging to the container body and the edge of the outer portion of the bulging portion belonging to the reseal lid.
As described above, since the sealing lid member for sealing forms a reseal lid in cooperation with the outer region of the flange portion of the container body after opening, it is possible to reduce the number of parts without requiring a reseal lid separately. it can.

Hereinafter, the container which makes 1st Embodiment of this invention is demonstrated, referring FIGS. The container of this embodiment is for accommodating food materials and the like.
Initially, the structure of a container is demonstrated, referring FIG. 1, FIG. 2 (A), (B), FIG. 6 (A), (B). The container is composed of a container body 10 and a seal lid member 20.
The container main body 10 is obtained, for example, by vacuum press molding a resin sheet, and includes a housing portion 11, a flange portion 12 that continues to the opening peripheral edge 11 x of the housing portion 11 and projects radially outward, and the flange portion 12. It has a drooping portion 13 that continues to the outer peripheral edge 12x. The accommodating part 11 is comprised by the bottom part 11a and the trunk | drum 11b.

As shown in FIG. 1, the bottom portion 11a of the housing portion 11 has an octagonal shape that is close to a substantially regular octagon, and the opening peripheral edge 11x has a substantially similar octagon shape slightly larger than the bottom portion 11a.
The outer peripheral edge 12x of the flange portion 12 is substantially square (quadrangle) except for rounded corners. The four sides of the opening periphery 11x are parallel to the four sides of the outer periphery 12x. The other four sides of the opening periphery 11x cooperate with the four corners of the outer periphery 12x to provide four substantially triangular regions 12y.

Two first fitting portions 15 and two second fitting portions 16 are formed in the center of the four triangular regions 12 y of the flange portion 12. The first fitting portions 15 and the second fitting portions 16 are alternately arranged in the circumferential direction. The two first fitting portions 15 are arranged on the opposite sides with the accommodating portion 11 in between. More specifically, they are 180 degrees apart in the circumferential direction. The two second fitting portions 16 are also arranged on the opposite side with the accommodating portion 11 in between (they are separated by 180 ° in the circumferential direction).
The first fitting portion 15 and the second fitting portion 16 are separated by 90 ° in the circumferential direction, and are equidistant from the center L of the housing portion 11.

  The flange portion 12 is formed with a planned cutting line 17 that draws an annular line, and a raised portion 18 that draws the annular line along the planned cutting line 17 on the radially inner side of the planned cutting line 17. In FIG. 1, the scheduled cutting line 17 is indicated by a broken line, and in FIGS. 2A, 2 </ b> B, 6 </ b> A, and 6 </ b> B, the position of the scheduled cutting line 17 is indicated by a one-dot chain line.

  The scheduled cutting line 17 may be a perforation formed of a large number of cuts formed at intervals in the flange portion 12, or may be a continuous V groove formed on the upper surface or the lower surface of the flange portion 12. The scheduled cutting line 17 is more fragile than other parts of the flange portion 12, and can be easily cut by an external force applied by the user. The raised portion 18 is slightly raised from the upper surface of the flange portion 12 (for example, about 0.5 mm).

  As shown in FIG. 1, the planned cutting line 17 and the raised portion 18 are formed along the outer peripheral edge 12 x of the flange portion 12 except for the triangular region 12 y where the second fitting portion 16 is formed. In the triangular region 12y in which the second fitting portion 16 is formed, extending in parallel, it extends close to the side of the opening peripheral edge 12x of the accommodating portion 11 and in parallel with the side. As a result, the planned cutting line 17 and the raised portion 18 pass outside the first fitting portion 15 and pass inside the second fitting portion 16.

  The flange portion 12 is divided into an inner region 12a and an outer region 12b by the cut line 17 described above. The first fitting portion 15 and the raised portion 18 are disposed in the inner region 12a, and the second fitting portion 16 is disposed in the outer region 12b.

  As shown in FIGS. 2A and 2B, the first fitting portion 15 and the second fitting portion 16 are bulged so as to protrude downward, and the diameter gradually increases downward.

The second fitting portion 16 has a smaller diameter than the first fitting portion 15 by the thickness. The lower end outer diameter (maximum outer diameter) of the second fitting portion 16 is slightly larger than the upper end inner diameter (minimum inner diameter) of the first fitting portion 15.

  2 (A), 2 (B), 6 (A), and 6 (B), after the container 11 of the container body 10 is filled with food, the seal lid member 20 is placed on the flange 12. Heat welded. More specifically, the seal lid member 20 is made of, for example, a resin film or a resin sheet, and has a square shape corresponding to the flange portion 12. The seal lid member 20 is thermally welded to the outer region 12b of the flange portion 12 and the raised portion 18, whereby the internal space of the housing portion 11 is sealed, and the food material can be prevented from being falsified and deteriorated.

  The user who has purchased the container containing the above-described foodstuff uses his / her finger to point out one of the two triangular regions 12y (the triangular region 12y in which the second fitting portion 16 is formed) in the outer region 12b of the flange portion 12. By cutting and bending upward, the cutting planned line 17 in this region 12y is cut. Further, by pulling up the region 12y, the planned cutting line 17 is cut over the entire circumference.

  By cutting along the planned cutting line 17, the container is separated into the container body 10A and the reseal lid 20A as shown in FIG. 6C. At this time, the welding between the raised portion 18 and the seal lid member 20 is also released, and the user can take out the food from the opened accommodating portion 11.

  As shown in FIGS. 3A and 6C, the container body 10A is obtained by removing the outer region 12b of the flange portion 12 from the container body 10 in the initial state. It has an inner region 12a. The first fitting portion 15 and the raised portion 18 belong to the container body 10A.

  As shown in FIGS. 3B and 6C, the reseal lid 20A has an outer region 12b of the flange portion 12, a drooping portion 13, and a seal lid member 20 welded to the outer region 12b. ing. The second fitting portion 16 belongs to the reseal lid 20A.

  In the reseal lid 20A, the seal lid member 20 has flexibility, but the outer region 12b and the hanging portion 13 of the flange portion 12 are part of the container body 10 in an initial state that is a molded product. Although it can be elastically deformed, it has shape retention (predetermined rigidity) and serves as a frame of the reseal lid 20A.

  The accommodating portion 11 of the container main body 10A can be resealed by the reseal lid 20A. At this time, by turning the resealing lid 20A by 90 ° from the position immediately after being separated from the container body 10A, as shown in FIGS. 4, 5A and 5B, the second fitting of the resealing lid 20A is performed. The joint portion 16 is aligned with the first fitting portion 15 of the container body 10 </ b> A, and the second fitting portion 16 is fitted into the first fitting portion 15. As is clear from the comparison between FIG. 1 and FIG. 4, the reseal lid 20 </ b> A is only turned 90 °, and there is no significant change in the positional relationship with respect to the accommodating portion 11, and the opening of the accommodating portion 11 is covered with the seal lid material 20. A resealable state is obtained.

Since the outer diameter of the lower end portion of the second fitting portion 16 is slightly larger than the inner diameter of the upper end portion of the first fitting portion 15, the lower end portion of the second fitting portion 16 passes through the upper end portion of the first fitting portion 15. Moreover, these fitting parts 15 and 16 are accompanied by elastic deformation.
The first fitting portion 15 and the second fitting portion 16 are fitted at two locations that are 180 ° apart, and are fitted with elastic deformation as described above, whereby the reseal lid 20A is placed in a container. The main body 10A can be securely held.
