Description

  The present invention relates to a packaging inner frame for enhancing the appearance of a boxed product, and relates to a packaging inner frame that allows a member to be handled in a low volume during a boxing operation.

  There exists patent document 1 as what arrange | positions an inner case in a cardboard case.

JP 2002-019774 A (summary, drawing)

  The case described in the above patent document is to fit the inner case into the outer case. However, both the outer case and the inner case are bulky and require a large space for transportation and storage, and the space for transportation and storage is reduced. There is no choice but to put the blank into a blank state, and the blank must be folded and assembled when the product is packaged.

  In view of the above situation, this device can be overlapped with a low bulk in a generally assembled state before use, and when packaging products, the inner case (expressed as “inner frame” in the present invention) can be easily operated. It is an object of the present invention to provide an inner packaging frame that can be stored inside.

  In order to solve the above problems, the present invention provides outer wall pieces 13a and 13b on the outer side of the upper edge around the edge 11 via folding lines 12, and inner wall pieces 15a and 15a on the inner side of the edge around the upper edge 11 via folding lines 14a and 14b. 15b is provided, flaps 17 are provided at both ends of the outer wall piece 13a via folding lines 16a and 16b, and at least the outer wall piece 13a is engaged via the flap 17 so that the hem is widened. The engagement is made by inserting the locking piece 18 provided in the flap 17 into the partial circular hole 19 provided in the shape of a letter C at both ends of the outer wall piece 13b, or the notch 28 put in the flap 17 and the outer wall. It is formed by multiplying an inclination, a taper, and a wide cut 29 placed in the piece 13b.

  Further, the folding line 14a may be formed so as to face each other intermittently, and a convex cut 20 may be formed at a portion where the folding line 14a is interrupted.

  According to the present invention configured as described above, the outer wall piece is bent along the folding line and the inclined folding line, and the locking piece is inserted into the partial circular hole or the notch is engaged with the outer wall piece. Since the lower end can be widened or narrowed, the bulk can be reduced during transportation, storage and packaging. Further, when the inner wall piece is folded, the partition piece remains, and the effect of preventing the swing of the packaged product can be obtained.

  Next, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 show a packaging inner frame according to the first embodiment. Outer wall pieces 13a and 13b are provided on the outer side of the upper end periphery 11 via folding lines 12, and the folding lines 14a and 14b are provided on the inner side of the upper end periphery 11, respectively. Inner wall pieces 15a and 15b are provided. Note that the corners of the folding lines 14a and 14b between the upper edge 11 and the inner wall pieces 15a and 15b have a quarter arc cut 23 and a 45 ° cut 24, respectively.

  Further, the folding line 14a can be intermittently faced and interrupted, and a convex notch 20 having an arcuate waveform (which may be trapezoidal) can be provided at the interrupted portion. If it does in this way, when the inner wall piece 15a is bent, the partition piece 26 will remain and the swing prevention effect of the packaged product H can be obtained as shown in FIG.

  Flaps 17 having locking pieces 18 are provided at both ends of the outer wall piece 13a via folding lines 16a and inclined bending lines 16b, and partial circular holes 19 into which the locking pieces 18 are fitted at both ends of the outer wall piece 13b. Is provided in a C-shape. Note that the flap 17 may be provided directly via the fold line 16a instead of the inclined fold line 16b, and the notch is provided between the end edge 22 of the flap 17 and the outer wall piece 13b. This is because it is easy to insert the locking piece 18 into the partial circular hole 19.

  When the blank shown in FIG. 1 is used as the inner frame 10, the inner wall pieces 15a and 15b are folded along the folding lines 14a and 14b, and the outer wall pieces 13a and 13b are folded along the folding line 12, as shown in FIG. The flaps 17 provided at both ends of the outer wall piece 13a are bent along the folding line 16a, and the locking piece 18 is inserted into the partial circular hole 19 (see FIG. 3A).

  When the engaging piece 18 is inserted, the constricted portion 21 of the engaging piece comes into contact with the lower end of the partial circular hole 19, and when both ends of the outer wall piece 13b are positioned on the inclined fold line 16b, the lower end of the outer wall piece expands at the bottom. 3 (b), the edge 22 of the flap 17 abuts on the upper end of the partial circular hole 19, and both ends of the outer wall piece 13b are positioned on the folding line 16a. As shown in FIG. 3C, the outer wall pieces 13a and 13b stand upright and can be easily placed in a case (not shown).

  4 to 6 are the first example of the second embodiment, and FIGS. 7 to 9 are the second example of the second example. The basic structure is the same as that of the first example, and the outer wall pieces 13a and 13b are provided with the flaps 17. Since only the structures to be engaged are different, different portions will be described.

  The flap 17 is provided with a cut 28 that is inclined from the inside to the outside and upward toward the free end. The entrance of the cut 28 is chamfered, and the other corners are chamfered.

  Near the both ends of the outer wall piece 13b, there is a cut-out 29 that has a square shape and gradually decreases in width toward the back, and the entrance of the cut 29 is chamfered, and the other corners are also chamfered, The width of the cut 29 is wider than the width of the cut 28 so that the outer wall piece 13a can be widened.

  As shown in FIGS. 5 and 6, the cut 28 and the cut 29 are bent so that the outer wall pieces 13a and 13b are bent, and the flap 17 is bent at the fold line 16a to engage the cut 28 and the cut 29 with each other. .

  Since the cuts 28 and 29 are inclined, the cuts 28 and 29 act so that when the outer wall piece 13a tries to recover, the cuts 28 and 29 are deeply engaged with each other. Therefore, the outer wall piece 13a is widened as shown in FIGS. 5 and 6, and can be stacked with a low bulk as shown in FIG. 3 (b).

  FIGS. 7 to 9 show part 2 of the second embodiment, which is different from part 1 in that folding lines 16a and 16b are provided at the bent portions of the flap 17 provided at both ends of the outer wall piece 13a.

  By providing the folding line 16b in this way, the outer wall piece 13b can also be expanded at the bottom, making it easy to stack with low bulk.

  In addition, when the folding line 14a is formed so as to face each other intermittently, and a convex (arc-shaped corrugated or trapezoidal) cut 20 is made in a portion where the folded line 14a is interrupted, the portion of the cut 20 is obtained when the inner wall piece 15a is bent. As shown in FIG. 10, the effect of preventing the roll of the packaged product H (for example, ham) is obtained.

In order to improve the appearance of the packaged product, the wrapping cloth and the nonwoven fabric 25 are covered with a margin as shown in FIGS. 1, 2, 4, 5, 7, and 8 on the inner packaging frame described above, For example, the inner frame 10 in which products are stored on the woven fabric and the non-woven fabric 25 can be packaged in a case composed of an inner box C ₁ and a lid box C ₂ (see FIG. 10).

  As described above, according to the present invention, it is possible to reduce the bulk before packaging work, and it can be placed in a case (not shown) by a simple operation during packaging. Further, when the inner wall piece is folded, the convex cut remains and the partition effect is exhibited.
