Description

  The present invention relates to a container, and more particularly to a container that can be closed again (simply re-sealed) by closing the once-opened lid member again.

  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.

  It is an object of the present invention to provide a container having a novel opening resealing structure.

  The container according to the present invention is bonded to the curled portion, a cylindrical barrel portion having a curled portion formed at the peripheral edge of the upper edge, a bottom portion provided at the lower end of the barrel portion so as to close the lower surface thereof, A lid member for closing the upper surface of the body part, wherein the body part is formed in a cylindrical shape by bonding both side parts of the blank material, and both sides of the blank material constituting the body part A clip piece used to fasten the edge portion of the lid material partially peeled off from the curled portion to the curled portion is continuously provided on the side edge of the side portion that is the outside of the bonding of the portions. It is characterized by.

  The upper end 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 on the upper edge of the upper portion of the trunk portion, and the upper end opening is closed. 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 resin film or the like is provided on the inner surfaces of the trunk and the bottom as required.

  The body portion is formed in a cylindrical shape by bonding both side portions of the blank material. If the blank is rectangular, a body having a constant diameter in the vertical direction is formed. By forming the blank material in a slightly arcuate shape in the longitudinal direction, a body having a slightly larger upper diameter than the lower part can be formed.

  A clip piece is connected continuously to the edge of the side part which becomes the outside of bonding among both side parts of the blank material which constitutes the above-mentioned drum part. A cut line may be formed at the boundary between the side edge of the blank material and the clip piece. Cut lines are realized by, for example, a plurality of cut lines connected by a short connecting portion, or a perforation that intermittently connects a plurality of cut lines. When both side portions of the blank material constituting the body portion are bonded together, the clip piece is positioned outside the body portion.

  The clip piece is either the one that sandwiches the lid and the curled part together (overlapping) from both sides (up and down), or the one that pushes the lid against the curled part and thereby sandwiches the lid between the curled part It may be. In any case, the lid material that has been partially peeled off partway is simply fastened again to the curled portion by the clip piece, and the opening at the upper end of the trunk portion is resealed by the lid material.

  According to the present invention, the clip piece provided integrally with the body portion is cut off from the body portion, and the clip portion that has been cut off has the edge of the lid material partially peeled off from the curl portion as the curl portion. Since it is used to fasten again, there is no need to use a completely separate member from the container, such as an adhesive tape. In addition, since it is only necessary to connect the clip pieces to the body portion so as to be detachable, no special processing is required to form the clip pieces. The container can be given resealability at low cost.

  Depending on the material composing the body (clip piece), the repulsive force of the material causes the clip piece to face outward (not between the body and the clip piece) without being along the outer surface of the body. It may become. In one embodiment, the clip piece is partially bonded to the outer surface of the barrel. The clip piece located on the outer side of the trunk portion can be arranged along the outer surface of the trunk portion. Since the clip piece is used by being separated from the body portion as described above, the clip piece is preferably bonded to the outer surface of the body portion easily, for example, within a small range.

  The invention also provides a double container. A double container according to the present invention includes a cylindrical barrel portion having a curl portion formed at a peripheral edge of an upper edge, 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 is covered and fixed to the body so as to form a heat insulating space between the outer wall and a lid that is bonded to the curl and closes the upper surface of the body. The outer cylinder is formed into a cylindrical shape by bonding both side portions of the blank material, and of the both sides of the blank material constituting the outer cylinder, the edge of the side portion that is the outside of the bonding Further, a clip piece used to fasten the edge of the lid material partially peeled off from the curled portion is connected to the curled portion so as to be detachable.

  The clip piece provided integrally with the outer cylinder is cut off from the body portion, and the cut clip piece is used to re-fasten the edge of the cover material partially peeled off from the curl portion to the curl portion. It is done. Also in this invention, the container can be resealed without using a member completely different from the container, such as an adhesive tape.

It is a perspective view of the container in a state.

  The container 1 includes a lid member 10, a body portion 12, and a bottom portion 13. The container of the first embodiment is hereinafter referred to as “single container” in order to make it easier to distinguish from the double container described in the second embodiment to be described later.

  The body 12 of the single container 1 has a cylindrical shape with a large diameter at the top and a diameter that decreases as it goes down, and the upper surface that is opened is closed by a lid 10. A so-called curled portion 11 is formed by winding the upper peripheral edge portion of the body portion 12 outward. The bottom portion 13 is circular, and its peripheral end portion is bent downward (bent portion 13A). The bottom portion 13 fits snugly into the lower surface opening of the body portion 12, and the lower end portion of the body portion 12 is folded back inside (folded portion 12A), and the folded portion 12A sandwiches the bent portion 13A of the bottom portion 13. Both the inner and outer surfaces of the bent portion 13A of the bottom portion 13 and the inner surface of the folded portion 12A at the lower end portion of the body portion 12 sandwiching the bent portion 13A are bonded or welded by a thermoplastic resin.

  The barrel 12 of the single container 1 is formed in a cylindrical shape by bonding the sides of a blank material (Fig. 3) formed in an arc shape, then curling the upper end outward and bending the lower end inward It is formed by letting. The bonding portion 12B used for bonding the side portions is shown by a dot pattern in FIG.

  The cover material 10 is a laminate of a sealant layer for bonding the cover material 10 on the upper surface of the curled portion 11, a paper layer for printing characters, figures, etc., and a protective layer for protecting the paper layer. Is used. An aluminum layer for maintaining the shape may be laminated between the sealant layer and the paper layer. For the body portion 12 and the bottom portion 13, for example, a paper base material and a laminated structure such as a polyethylene film laminated on the inner surface thereof are used.

  Referring to FIG. 3, a clip piece (reclose piece) 21 is continuously provided at an edge of one side portion of the trunk portion 12. At the boundary between the body portion 12 and the clip piece 21, a cut line 21A is formed except for the central portion, for example, a plurality of cut lines connected by short connecting portions, a perforation that intermittently connects the cut lines, and the like. . The clip piece 21 has a substantially square shape, and one side thereof has an arc-shaped bulge outward. The shape of the clip piece 21 is not limited to a square, and may be a circle, an ellipse, a triangle, or any other shape.

  On one side of the clip piece 21 (on the side opposite to the side that bulges outward), an elongated concave cut line 21B that extends partway in the lateral direction toward the inside of the clip piece 21 is also formed. Referring to FIG. 4, a groove portion 21 </ b> C extending in the lateral direction is formed in the clip piece 21 by cutting out a part of the clip piece 21 along the cut line 21 </ b> B. The interval (the size of the gap) between the groove portions 21C is slightly narrower than the thickness of the curled portion 11 formed at the peripheral edge portion of the upper edge of the trunk portion 12.

  Referring to FIG. 1, when the cylindrical body 12 is formed by bonding and bonding the sides of the blank material, the side to which the clip piece 21 is connected is on the outside and the side on the opposite side. Lay the sides together. As a result, the clip piece 21 is positioned outside the trunk portion 12.

  The clip piece 21 is cut off from the trunk portion 12 along the cut lines 21A and 21B. The clip piece 21 cut off from the body portion 12 returns the lid 10 that has been peeled off halfway to its original position and closes the opening of the single container 1 again (reseals). Used to easily fix (hold) to the container 1. Referring to FIG. 4, the edge portion of the cover member 10 and the curled portion 11 are overlapped and inserted together into the groove portion 21 </ b> C of the clip piece 21 separated from the body portion 12, and the cover member is inserted by the groove portion 21 </ b> C of the click piece 21. By sandwiching (clipping) 10 and the curled portion 11, the cover material 10 that has been peeled off halfway is fastened to the curled portion 11 of the single container 1, whereby the single container 1 is easily resealed. Since the gap between the groove portions 21C of the clip piece 21 is narrower than the thickness of the curled portion 11, the lid member 10 and the curl 11 are tightly sandwiched between the groove portions 21C. Since the body part 12 is made of paper, the clip piece 21 cut out from the body part 12 is also made of paper. It is easy to remove the clip piece 21 by pulling the clip piece 21 outward.

  Since the clip piece 21 is provided integrally with the body portion 12 constituting the single container 1, a separate cover is used to return the lid 10 that has been peeled off halfway to the original place and reseal the opening of the single container 1. There is no need to prepare a member (adhesive film, tape, etc.). Since the clip piece 21 has only to be connected to the body 12 via the cut line 21A, no special processing is required. The reseal function of the single container 1 is realized at low cost.

  As shown in FIG. 5, an adhesive 21 </ b> D may be provided in a narrow area on the inner surface of the clip piece 21, and the clip piece 21 may be simply adhered to the outer surface of the body portion 12. The clip piece 21 is prevented from facing outward by the repulsive force of the paper (a gap is formed between the outer surface of the body 12 and the clip piece 21). However, when the entire single container 1 is packaged with a shrink film or the like, the clip piece 21 is pressed against the outer surface of the body portion 12 by the shrink film, and in this case, the adhesive 21D is not necessarily required.
