And a curling portion formed at the upper end, and a substantially V-shaped slit formed on the upper portion except for the adhesive portions at both ends, and a curling portion of the outer cylindrical portion. The outer cylinder having an inner cylinder corresponding to the outer diameter of the inner cylinder and having a height slightly larger than the height of the inner cylinder. It is characterized by being fitted on the outer peripheral surface of the inner cylinder.

  According to the present invention, the inner cylinder body and the outer cylinder body are individually assembled, and the outer cylinder body is fitted into the inner cylinder body to form the paper can container. Can be surely sealed. Then, by tearing along the slit formed in the outer cylinder and separating it into an upper part and a lower part, the upper part of the outer cylinder provided with the top plate is used as the hinge at both ends of the outer cylinder. By rotating with respect to the lower part, it can function as a lid for opening and closing the upper end opening of the inner cylinder.

  As a result, the both-end bonded portion of the outer cylindrical body in which no slit is formed becomes a hinge, so that the upper portion of the outer cylindrical body as a lid can be prevented from falling off, and the outer peripheral surface of the inner cylindrical body can be The upper end opening of the inner cylinder can be easily opened and closed as a guide for opening and closing. Further, no irregularities occur on the outer peripheral surface of the paper can container, and the design is excellent. Further, since the inner cylinder is assembled separately from the outer cylinder, the product accommodated in the inner cylinder can be sealed with a sealing material, and contamination of foreign matters in the manufacturing process is prevented as much as possible. be able to.

  According to the present invention, since there is no unevenness, the design is excellent, and even when the sealing material that seals the upper end opening of the product housing portion is peeled off, the lid portion is prevented from falling off and the upper end opening can be easily made.

  The outer cylindrical body 3 is composed of an outer cylindrical portion 31 and a top plate 32 in the developed view of FIG.

  The outer cylinder part 31 is formed such that a glue margin 312 is connected to the left end edge of the outer cylinder body 311 and a curling forming part 312 is connected to the upper end edge of the outer cylinder body 311 via a fold line 31a. . The outer cylinder main body 311 of the outer cylinder part 31 is formed with a glue margin 312 and fold lines 31b and 31b extending in the lateral direction symmetrically on the right end edge attached to the glue margin 312 in the vicinity of the upper end portion thereof. In addition, a pair of slits 31c and 31c that descends substantially linearly toward the center continuously from the inner end edges of these fold lines 31b and 31b are substantially V-shaped as a whole. It is formed symmetrically. A substantially elliptical hole 31d is formed at a substantially central portion in the left-right direction of the outer cylinder main body 311 of the outer cylinder 31 so as to straddle the pair of slits 31c and 31c.

  In addition, the outer cylinder main body 311 of the outer cylinder part 31 is formed in the square of the horizontal dimension equivalent to the outer periphery length of the paper can container 1, and the vertical dimension equivalent to the height.

  The top plate 32 is formed as a disc having a diameter substantially corresponding to the diameter of the outer cylinder portion 31.

  Next, a procedure for assembling the paper can container 1 configured as described above will be described.

  First, the inner cylinder portion 21 and the bottom plate 22 are punched out from the coated ball according to the developed view of FIG. And after reversing so that the back surface of the inner cylinder part 21 may face the upper surface, after apply | coating an adhesive agent on the surface of the glue margin 212, the inner cylinder part 21 is rounded cylindrically and the back surface side left end of the inner cylinder part 21 A cylindrical body is formed by sticking to the rear surface of the edge and having both upper and lower ends opened. Next, after the cylindrical inner cylinder portion 21 is turned upside down so that the folding formation portion 214 of the cylindrical inner cylinder portion 21 is positioned above, the folding formation portion 222 of the bottom plate 22 is turned upside down. It rises along the fold 22a to form a folded portion 222A (see FIG. 3), and an adhesive is applied to the outer peripheral surface of the folded portion 222A of the bottom plate 22 so as to be inward of the cylindrical inner cylinder portion 21. Insert and stick to the inner peripheral surface. At this time, the upper end edge of the folded portion 222 </ b> A of the bottom plate 22 is attached along the fold line 21 b between the inner cylinder main body 211 and the folded formation portion 214 in the cylindrical inner cylinder portion 21. Next, an adhesive is applied to the inner peripheral surface of the fold forming portion 214 of the cylindrical inner cylinder portion 21, and is folded inwardly of the inner cylinder portion 21 along the fold line 21b (see FIG. 3). ) And is attached to the inner peripheral surface of the folded portion 222A of the bottom plate 5 previously attached.

  After the bottom plate 22 is pasted, the cylindrical inner cylinder portion 21 is turned upside down again so that the curling forming portion 213 in the cylindrical inner cylinder portion 21 is positioned upward. Then, the curling forming portion 213 of the inner cylindrical portion 21 is curled inward to form an inner curling portion 213A (see FIG. 3). Then, after supplying a set number of gums to the inside of the cylindrical inner cylinder part 21 with the bottom plate 22 attached and the lower end side opening part closed, an adhesive is applied to the top part of the inner curling part 213A. And if the periphery of the sealing material 23 is stuck, the inner cylinder 2 in which the gum was accommodated inside can be formed.

  Thereby, in a manufacturing process, the opportunity that a foreign material mixes in the inside of the inner cylinder 2 can be reduced as much as possible.

  On the other hand, the outer cylinder part 31 and the top plate 32 are punched out from the court ball according to the development view of FIG. And after reversing so that the back surface of the outer cylinder part 31 may face an upper surface, after apply | coating an adhesive agent on the surface of the glue margin 312, the outer cylinder part 31 is rounded cylindrically and the back surface side left end of the outer cylinder part 31 A cylindrical body is formed by sticking to the rear surface of the edge and having both upper and lower ends opened. Next, after the cylindrical outer cylinder portion 31 is erected so that the curling formation portion 312 in the cylindrical outer cylinder portion 31 is located above, the curling formation portion 312 of the outer cylinder portion 31 is moved inward. Curling is performed to form the inner curling portion 312A (see FIG. 4). And if an adhesive agent is apply | coated to the top part of 312A of inner side curling parts, and the periphery of the top | upper surface board 32 is stuck, the outer cylinder 3 can be formed.

  A wrapping paper 10 is attached to the back surface of the top plate 32 to wrap and discard the chewing gum gum.

  If the inner cylinder 2 and the outer cylinder 3 sealed with gum are formed, the outer cylinder 3 is fitted from above the inner cylinder 2, and the outer cylinder 3 is fitted to the outer peripheral surface of the inner cylinder 2. Are inserted into the paper can container 1. Thereafter, although not shown in detail, the paper can container 1 is packaged with a film and shipped.

  On the other hand, a consumer who has purchased gum at a store, after peeling off the film, rotates the upper portion of the outer cylinder 3 by grasping the upper portion of the outer cylinder 3 from the slit 31c and pulling it upward. Thus, the upper end portion of the inner cylindrical body 2 can be opened.

  That is, when the upper part of the outer cylindrical body 3 is gripped and rotated in the direction of lifting upward while putting the fingertip on the periphery of the elliptical hole 31d, the tear 31c formed in the outer cylindrical body 3 is cut and glue The upper portion 312 and the side edge portion of the outer cylinder portion 31 attached to the adhesive margin 312 are separated into an upper portion and a lower portion. And the upper part of the outer cylinder body 3 cut off with the folds 31b and 31b formed on the side margins of the glue margin 312 and the outer cylinder part 31 adhered to the glue margin 312 as a hinge rotates, The upper end part of the inner cylinder 2 can be opened.

  If the upper end of the inner cylinder 2 is opened, if the knob 231 of the seal member 23 of the inner cylinder 2 is picked up and pulled up, the seal member 23 is peeled off from the upper end opening of the inner cylinder 2, The upper end opening can be opened. Therefore, the gum accommodated in the inner cylinder 2 can be taken out through its upper end opening.

  On the other hand, when the upper end opening is closed after the gum is taken out, if the upper portion of the outer cylinder 3 is grasped and pushed down, the side of the outer cylinder portion 31 attached to the adhesive margin 312 and the adhesive margin 312 The upper part of the outer cylinder 3 can be rotated by using the folds 31b and 31b formed at the end edge as hinges, and can be fitted to the outer peripheral surface of the inner cylinder 2 to close the upper end.

  As a result, the part where the slit 31c is not formed, that is, the glue margin 312 and the folds 31b and 31b formed at the side edge of the outer cylinder main body 311 to which the glue margin 312 is attached are separated as hinges. Since the upper part of the outer cylinder 3 is rotated, it is possible to prevent the upper part of the outer cylinder 3 as a lid from falling off. In addition, since the inner cylinder 2 fitted on the inner peripheral surface of the outer cylinder 3 functions as a guide for opening and closing the upper portion of the outer cylinder 2, the upper end of the inner cylinder 2 is easily opened. Alternatively, it can be closed, and the outer peripheral surface of the outer cylindrical body 3 is not uneven, so that an uncomfortable feeling does not occur when advertising is performed on the outer peripheral surface, and the design is excellent.

  Furthermore, since the upper part of the outer cylinder 3 can be used as a lid even after the sealing material 23 of the inner cylinder 2 is peeled off, the sealing property of the gum accommodated in the inner cylinder 2 is ensured. Can be hygienic.

  In addition, in embodiment mentioned above, although gum was illustrated as an accommodation goods of an inner cylinder, it is not limited to gum and various goods can be accommodated.
