Description

  The present invention relates to a double container, and more particularly, to a double container that can be closed once again after being opened again (for easy re-sealing).

  There is a container whose upper end opening is closed by a lid. In some of these containers, it is desirable to re-seal the cover material that has been peeled off halfway, typically temporarily (reseal the opening with the cover material). For example, in instant noodles with a cup, the lid is peeled off halfway, and hot water is poured into the cup from a cup opening that is about half open. The lid material peeled off by about half is used for easily resealing the cup opening, and is completely peeled off after a predetermined time. For containers containing confectionery, etc., if there is leftovers, the lid may have been removed halfway and the cup opening may be simply resealed.

  Patent document 1 describes what re-seal | closes a cup by providing the tab in which the notch was formed in two places where the periphery of a cover material opposes, and pinching the flange part of a cup in the notch notch of this tab.

JP 2001-180737 A

  In the cup described in Patent Document 1, the tab formed on the peripheral edge portion of the lid member is also used as a knob when the lid member is peeled off. Since the notch is formed in the tab, the tab may be torn from the lid along the notch when the lid is peeled off.

  The present invention provides a resealing structure for an opening suitable for a double container having an outer cylinder on its body.

  The present invention also realizes the resealing of the opening without the need to add a separate member for resealing to the conventional double container and without requiring special processing.

  The present invention further provides a reseal structure of an opening that does not generate dust.

  A double container according to the present invention comprises a cylindrical barrel portion having a curl portion formed at an upper end periphery thereof, a bottom portion provided at a lower end of the barrel portion so as to close a lower surface thereof, and an outer side of the barrel portion. An outer cylinder that covers and is fixed to the body so as to form a heat insulating space therebetween, and a lid that is bonded to the curl and closes the upper surface of the body. A clip line is formed, and a clip piece that is completely or partially cut off from the outer cylinder along the cut line is used to hold the edge of the lid material partially peeled off from the curled part to the curled part. It is used.

  The upper surface of the trunk portion is open, and after the contents are accommodated in the trunk portion, the lid member is bonded to the curled portion formed at the upper edge of the trunk portion. The barrel is generally cylindrical with an upper diameter slightly larger than that of the lower portion, but may have a constant diameter in the vertical direction, or may be a rectangular tube with a polygonal cross section. A protective film is provided on the inner surfaces of the trunk and the bottom as necessary.

  The cut line formed in the outer cylinder is realized by, for example, a plurality of cut lines connected by short connecting portions, or a perforation that intermittently connects the cut lines.

  A clip piece is cut from the outer cylinder along a cutting line formed in the outer cylinder. Since the outer cylinder does not directly store the contents but covers the outside of the body, the contents do not come out of the clip even if a clip piece is cut off from the outer cylinder.

  The clip piece may be completely cut off from the outer cylinder, or it is not completely cut off from the outer cylinder, but a part of the clip piece is connected to the outer cylinder (continuous), and the outer cylinder is It may be partly cut out from.

  The clip piece is one that sandwiches the cover material and curl part together (overlapping) from both sides (upper and lower), presses the cover material against the curl part, and thereby sandwiches the cover material between the curl part, Any of these may be used. In any case, the lid material partially peeled off halfway is simply fastened again to the curled portion by the clip piece, and the opening at the upper end of the trunk portion is thereby resealed by the lid material.

  According to the present invention, the clip piece cut from the outer cylinder along the cut line formed in the outer cylinder is used to re-fasten the edge of the lid material partially peeled off from the curled part to the curled part. Therefore, it is not necessary to use another member such as an adhesive tape. Further, since it is only necessary to form a cut line on the outer cylinder, no special processing is required to form the clip piece. Resealability can be given to the double container at low cost.

  Preferably, a notch portion is formed in the outer cylinder adjacent to a part of the range used as the clip piece of the outer cylinder. Since a nail or a finger can be put on the edge of the clip piece from the notch portion, the clip piece can be easily cut along the cut line.

  The outer shape of the clip piece can be any shape such as trapezoid, square, or circle. Further, as described below, the clip piece may have various shapes and structures.

  In one embodiment, the clip piece is formed with a groove portion on one side thereof into which the curl portion and the lid portion are inserted together. The groove portion may be formed in advance in the clip piece, or a cut line for forming the groove portion may be formed in the clip piece. The width of the groove portion is slightly narrower than the thickness of the curled portion. By inserting the curl portion and the edge of the lid portion tightly into the groove portion of the clip piece, the edge portion of the lid portion is simply fastened to the curl portion, and the upper end opening of the trunk portion is resealed.

  In another embodiment, the clip piece is provided with a first protrusion and a second protrusion that sandwich the curl portion and the lid portion from both sides (above and below respectively). The first protrusion and the second protrusion are, for example, a convex cut line that defines the first protrusion within a range cut as a clip piece of an outer cylinder, and a concave cut line that defines the second protrusion on both sides of the convex cut line. Is formed. When the clip piece completely separated from the outer cylinder is bent, a first protrusion and a second protrusion protruding in the same direction with a gap therebetween are formed. By inserting the curl part and the edge part of the lid part tightly between the first and second protrusions of the clip piece, the edge part of the lid part is simply fastened to the curl part, and the upper end opening of the trunk part is Resealed.

  In still another embodiment, the clip piece has an insertion hole into which the curl portion and the lid portion are inserted together. The insertion hole may be formed in the clip piece in advance, or a cut line for forming the insertion hole may be formed in the clip piece. The width of the insertion hole is slightly narrower than the thickness of the curled portion. By inserting the curled portion and the edge of the lid portion into the insertion hole of the clip piece, the edge portion of the lid portion is simply fastened to the curled portion, and the upper end opening of the trunk portion is resealed. A protrusion extending halfway toward the insertion hole may be formed on the clip piece. The clip piece can be stably fixed to the curl portion by hooking the protrusion on the inside of the curl portion.

  In still another embodiment, the clip piece is formed with a locking projection for locking the both end portions of the clip piece to the curl portion at each of both end portions thereof. For example, convex cut lines are formed at opposite ends of the elongated clip piece so as to face each other. When both end portions of the clip piece are bent in the same direction, locking projections along the convex cut line are formed in the opposite direction to the bent direction. By locking the locking protrusions at both ends of the clip piece to the curled part, the clip piece can be pressed lightly against the upper surface of the curled part or prevented from warping upward. The top opening of the part is resealed.

  In still another embodiment, the clip piece includes a hinge portion connected to the outer cylinder, and a protrusion that is rotated by the hinge portion and sandwiches an edge of the lid member between the curl portion. Yes. A cut line for forming the hinge part and the projection part is formed in the outer cylinder, and a part of the clip piece is cut from the outer cylinder along the cut line. The length of the hinge portion (the length of the cut line that defines the hinge portion) is determined such that when the hinge portion is rotated, the upper surface of the curl portion and the lower surface of the projection portion are substantially at the same height. Since the edge of the lid member is sandwiched between the protruding portion and the curl portion of the clip piece, the edge of the lid member is simply fastened to the curl portion, and the upper end opening of the trunk portion is resealed.

  Characters, symbols, or figures may be printed on the back surface of the clip piece. When the clip piece is cut out from the outer cylinder, characters printed on the back surface of the clip piece can be visually confirmed. The back side of the clip piece can be used as a lottery (printing characters of “win” or “off”), or can be used as a column for describing information about products.

  In place of or in addition to the back surface of the clip piece, characters, symbols, or figures may be printed on the surface of the body portion in a range corresponding to a location where the clip piece is cut from the outer cylinder. As described above, in the double container, since the outer cylinder is put on the outer side of the trunk part, the surface (outer surface) of the trunk part cannot be seen. When the clip piece is cut out from the outer cylinder, a hole is formed in the cut-out area, so that the surface of the body portion can be visually confirmed from there. When the clip piece is cut off, the characters printed on the surface of the body can be seen.

  The present invention also provides an outer cylinder constituting the double container described above.
