  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments. First, it demonstrates with reference to FIGS. FIG. 1 shows a top gripping carton or top gripping clip made from a blank (doughboard or blank) 10 made of a foldable sheet material, such as paperboard. The blank 10 includes a central panel 12 that constitutes the top wall panel of the carton in use. The first and second side wall panels 14, 16 are hinged to the side edges of the blank 10 along fold lines 18, 20, respectively.

  In the present embodiment, the folding lines 18 and 20 are interrupted by the article holding structures 22a and 22b provided from the first and second side wall panels 14 and 16, respectively. Since each structure is substantially the same, only the structure 22a will be described below.

  The article holding structure 22a includes a tab 25 having an upper edge defined by a first cut 24 and two opposing side edges defined by second and third cuts 26,28. In this embodiment, the cut 24 extends substantially parallel to the fold line 18 and is slightly offset from the fold line 18. As a result, a part of the top wall panel 12 protrudes into the side wall panel 14. In another embodiment, the first cut 24 is coextensive with the fold line 18. In yet another embodiment, one gap is formed adjacent to the tab 25. In the present embodiment, the second and third cuts 26, 28 are arranged substantially at right angles to the cut 24, define both ends of the cut 24, and extend from the fold line 18 to the side wall panel 14. Extending in.

  In the present embodiment, the lower edge of the tab 25 is defined by folding lines 32 a and 32 b arranged on both sides of the fourth cut 30. The fold lines 32a, 32b and the cut line 30 are preferably arranged as a continuous bent portion for the reason described below. In another embodiment, the fold lines 32a, 32b are straight lines.

  A pair of fold lines 34 a, 34 b that are parallel to each other at an interval extend between the cuts 24 and 30. The fold lines 34a, 34b are arranged substantially perpendicular to the cut 24 so that the tab 25 is warped from the plane of the side wall panel 14 when the carton is assembled as follows. ing. In other embodiments, score lines may be employed rather than fold lines, and the number and location of such fold lines may be varied.

  2-5 is a figure explaining the assembly of a carton. The carton of the present invention can be made by a continuous folding operation in a straight line machine, so there is no need to rotate or flip the carton to complete the assembly of the carton. . The folding process is not limited to the process described below and can be modified according to specific manufacturing requirements.

  As shown in FIG. 2, the blank is placed on the article A so that the top wall panel 12 lies on the lid of the article A. The dimensions of the top wall panel 12 are set so that the flange F of the article A extends outward beyond the fold lines 18 and 20. Then, the side wall panels 14, 16 are bent downward from the folding lines 18, 20, and the tab 25 is bent outward from the folding lines 32a, 32b due to the protruding position of the flange F.

  When the side wall panels 14, 16 are substantially perpendicular to the top wall panel 12, the free upper edge of the tab 25 automatically engages the lower surface of the flange F so that a portion of the flange F can be seen in FIG. It protrudes through the slit formed by the cut 24 shown in FIG. As clearly shown in FIG. 3, since the thickness t of the flange F is greater than the minimum width s of the slit, the tab 25 pivots outward with respect to the side wall panel 14 to accommodate the flange F. become.

  As shown in FIG. 5, once the sidewall panels 14, 16 are stationary, the sidewall panels inherently tend to bend upward and tend to regain their original position relative to the top wall panel 12. Therefore, a part of the region 38 of the side wall panel 14 is warped inward, and the tab 25 is combined with the compressive load applied to the tab 25 so that the bent lines 32a and 32b and the cut line 30 are bent in a curved shape. Therefore, it warps outward. As a result, as shown in FIG. 5, a gap 36 is formed between the side wall panel 14 and the tab 25, and the tab 25 acts like a column and tends to bend upward above the side wall panel 14. To counteract, thereby maintaining the top grip clip in an assembled state. The fold lines 34a, 34b help the tab 25 warp. In the present embodiment, the opposite article holding structure 22b operates in the same manner as the article holding structure 22a.

  In order to remove the carton from the article A, the end user (end user) restores the warped portion of the side wall panel and bends the side wall panel in the direction indicated by the arrow X in FIG. This overcomes the over-center resistance to bending due to warping of region 38 and tab 25. The side wall panel 14 is bent outward to release the article A from the article holding structures 22a and 22b.

  FIGS. 7 and 8 show a second embodiment of the present invention. In these drawings, prefixes “1” are added to the corresponding reference numerals for corresponding members that operate in the same manner as in the first embodiment. , Shown as reference numerals in the 100s. The blank 110 of the second embodiment has similar article holding structures 122a, 122b, 122c, 122d. That is, for the purpose of holding the two articles A, the four holding structures are provided.

  The blank 110 includes a top wall panel 112, a second side wall panel 116, a base wall panel 142, and a first side wall that are hingedly connected to each other at fold lines 120, 146, 148, 118. A panel 114 and a fixed panel 140 are included. In the present embodiment, openings 144 a and 144 b are provided in the base wall panel 142 to receive the main body of the article A. In another embodiment, the blank is dimensioned to form a complete wraparound system so as to surround and package both the top and bottom of the article.

  As shown in FIG. 8, the blank is preferably configured so that the carton can be assembled in a straight line machine. First, article A is placed through openings 144a, 144b, and fold lines 146, 148 are placed such that first and second sidewall panels 116, 114 are substantially perpendicular to base wall panel 142. Bend upward at The top wall panel 122 and the fixed panel 140 are preferably folded inward simultaneously at fold lines 120, 118 so that the top wall panel 112 is secured to the fixed panel using adhesive or other suitable means. A tubular carton is formed as shown in FIG. By the bending process described above, the flange F of the article A automatically protrudes through the slit formed by the cut 124, thereby setting up the tab 125 as in the first embodiment.

  In order to remove the article from the carton, the end user preferably separates the top wall panel 112 from the fixed panel 140 and then folds the side wall panel outward at fold lines 146 and 148 thereby causing the flange F to fold. Release from the slit. One or more articles can then be removed from the carton. If one or more articles A want to remain in the carton, the end user can re-introduce the flange F through the slit so that the top wall panel 112 is no longer secured to the stationary panel 140. The articles can be appropriately held in the carton by the article holding structures 122a, 122b, 122c, and 122d.

  FIG. 9 illustrates a third embodiment of the present invention, showing a top gripping carton made from a blank 210 made of a foldable sheet material, such as paperboard. Similar to the first embodiment, the blank 210 is hinged to the side edges of the top wall panel along the center panel 212 that forms the top wall panel of the carton in use and the interrupted fold lines 218, 220, respectively. And first and second side wall panels 214 and 216 fixed to each other.

  In the present embodiment, the side wall panels 214 and 216 are provided by one or more holding structures 222 provided on the first and second side wall panels 214 and 216 and along the folding lines 224 and 226. Are separated from the central panel 212 by intermediate (or diagonal) diagonal wall panels 217, 219 which are hingedly connected to the side wall panels 214, 216, respectively. The oblique wall panels 217 and 219 are connected to the central panel 212 along fold lines 218 and 220, respectively.

  FIG. 9 shows four article holding structures 222a, 222b, 222c, 222d for holding two articles, the number of article holding structures carrying one or more articles. Of course, it can be changed as appropriate.

  Since the respective article holding structures are substantially identical to each other, only the holding structure 222a will be described in detail below. The holding structure 222 a includes a tab 232, the upper edge of the tab 232 is defined by the first cut 228, and the side edge of the tab 232 is defined by the second and third cuts 242, 244. In this embodiment of the intermediate slant wall panel, the second and third cuts 242, 244 extend from the fold line 224 to the cut 228. The tab 232 is provided on the oblique wall panel 217 and the side wall panel 214.

  The fold line 224 may extend substantially parallel to the fold line 218 and may be slightly offset from the fold line 218. Thereby, a part of the top wall panel 212 protrudes into the side wall panel 214 to define a protruding portion 231.

  Similarly, in the present embodiment, the lower edge of the tab 232 is defined by fold lines 233 a and 233 b arranged on both sides of the fourth cut 230. In another embodiment, this fourth break is absent. The folding lines 233a and 233b and the cut line 230 are preferably arranged as a continuously bent portion for the following reason. In other embodiments, these fold lines 233a, 233b are straight lines.

  A pair of fold lines 236, 240 that are spaced apart and parallel to each other extend between the cuts 228 and 230. The fold lines 236, 240 are arranged substantially perpendicular to the fold line 224 so that the tabs 232 are warped from the plane of the side wall panel 214 when the carton is assembled as follows. Thus, the tab 232 includes outer tab portions 234, 238 that better conform to the shape of the article. In other embodiments, score lines may be employed rather than fold lines, and the number and location of such fold lines may be varied.

  In other embodiments, these fold lines 236, 240, 244a, 244b are omitted from the blank, and such embodiments are also within the scope of the present invention.

  One or more flaps 245a, 245b disposed along opposite side edges of the tab 232 may be provided, and these flaps are from the same plane relationship with the adjacent slant wall panels 217a, 217b. Can be bent and bent along the fold lines 244a and 244b, respectively. These flaps 245a and 245b can be engaged with the lower surface of the projecting flange of the article.

  FIG. 10 shows a fourth embodiment of the present invention. In this figure, for a corresponding member that operates in the same manner as the above-described embodiment, the prefix “3” is added to the corresponding reference symbol, and the reference numbers in the 300s are shown. Shown as a symbol. In the following description, only differences from the above-described embodiment will be described in detail. The blank 310 of the fourth embodiment has similar article holding structures 322a, 322b, 322c, and 322d in order to hold two articles A.

  A part of the article holding tab 322 is formed from the inclined wall panel 317 and a part thereof is formed from the side wall panel 314. In the present embodiment, bend lines 333 a and 333 b are disposed across the bend line 324 between the oblique wall panel 317 and the side wall panel 314. In this manner, the outer portions 334 and 338 of the tab 322 are hingedly connected to the oblique wall panel 317 and the side wall panel 314.

  In order to improve the warp of the tab, a slit 350 extending from the cut 328 to the tab 322 may be provided, and a tear preventing slit 352 may be provided at the end of the slit 350. In this case, when the carton is in use, the central portion 332 of the tab 322 will have a pair of flap portions 366, 368 that bend further outward, so that when the carton is set up, The upper edge of the defined tab better follows the shape of the flange. In addition, the tear prevention slit 352 acts to reduce stress from the slit to prevent undesired tears from occurring.

  Referring to FIGS. 9 and 11, the assembly of a carton from a blank will be described, with the blank placed on one or more items to be packaged so that the top wall panel 212 is above the lid of the item A. To lie on. Here, the top wall panel 212 is dimensioned such that the flange or lip L extends outward beyond the fold lines 218, 220. Next, the side wall panels 214 and 216 are bent downward at the folding lines 218 and 220, so that the tab 232 is bent outward at the folding lines 233a and 233b because of the protruding position of the flange L.

  At substantially the same time, the inclined wall panels 217 and 219 are bent at the folding lines 224 and 226 and inclined with respect to the side wall panels 214 and 216.

  When the side wall panels 214, 216 are perpendicular to the top wall panel 212, the free upper edge of the tab 232 automatically engages the lower surface of the flange L, with a portion of the flange L as shown in FIG. Projecting through the slit formed by the cut 228. As can be seen from FIG. 11, since the thickness of the flange L is greater than the minimum width of the slit, the tab 232 is positioned relative to the sidewall panel 214 along the fold lines 233a, 233b to receive the flange L. Will turn outward.

  As can be seen from FIG. 11, the outer portions 234, 238 will also be inclined relative to the central portion of the tab 232 to better follow the shape of the flange. Optionally, outer flaps 245a and 245b may be folded along fold lines 244a and 244b, respectively.

  Once the side wall panels 214, 216 are stationary, the side wall panels inherently tend to bend upward and tend to regain their original position relative to the top wall panel 212. A portion 239 of 214 warps inward, and the tab 232 is combined with the compressive load applied to the tab 232 and bent outwardly because of the curved lines of the fold lines 233a and 233b and the cut line 230. The As a result, a gap (not shown) is formed between the side wall panel 214 and the tab 232, and further, the tab 232 acts like a support column to offset the tendency to bend over the side wall panel 214. Acts as follows. In the present embodiment, the article holding structures 222b, 222c, and 222d operate in the same manner as the article holding structure 222a.

  In order to remove the carton from the articles A1 and A2, the end user (end user) restores the warped portion of the side wall panel 214 and bends the side wall panel in the direction indicated by the arrow X. This overcomes the over-center resistance to bending due to warpage of region 238 and tab 232 and releases articles A1, A2 from the carton.

  The carton of the fourth embodiment is assembled in the same manner as the carton of the third embodiment. A blank 310 is placed on one or more articles A1, A2 such that the top wall panel 312 lies on the lid L of the article A. Next, the side wall panels 314 and 316 and the slant wall panels 317 and 319 are bent downward similarly to the case of the third embodiment, and the tab 332 is bent to the folding lines 333a and 333b because of the protruding position of the flange L. Bend outward along. When the side wall panel is substantially perpendicular to the top wall panel 312, the free upper edge of the tab 332 automatically engages the lower surface of the flange L, and a portion of the flange L is shown in FIG. As such, it projects through the slit formed by the cut 328.

  To receive the flange L, the tab 332 pivots outward relative to the side wall panel 314 along fold lines 333a, 333b. As can be seen from FIG. 12, the outer portions 334, 338 are also folded along the fold lines 336, 340 and inclined with respect to the central portion of the tab 332, thereby better following the shape of the flange. become.

  FIG. 13 shows a fifth embodiment of the present invention, which is similar to the first embodiment. In this figure, for corresponding members that operate in the same manner as in the first embodiment, the prefix “4” is added to the corresponding reference numerals, and the reference numerals in the 400s are indicated. In the following description, only differences from the first embodiment will be described in detail.

  The cut 424 is not straight and the slits defined when the carton is assembled have different widths in cross section. This type of carton is therefore suitable for a flange with a stepped outer shape or a jar lid. Of course, this cut may have different shapes depending on the outer shape of the flange of the article. In the present embodiment, the folding lines 432a and 432b are formed so as to form a continuous curve with the cut line 430.

  Other points are the same as in the first embodiment, including the assembly of the carton.

  14 to 19 show a sixth embodiment of the present invention. In this embodiment, the blank 510 includes a plurality of pairs of article holding structures (of which 522a and 522b are a pair), for example, four holding structures to hold four articles A (see FIG. 19).

  The blank 510 has a series of panels to form a wraparound carton. That is, the inner base wall panel 512, the first outer base wall panel 513, the first side wall panel 514, which are continuously connected to each other by folding lines 519, 518, 520, 521, 523, A top wall panel 517, a second side wall panel 516, and a fixed panel 515 are included. In the present embodiment, four openings 550 are provided in the top wall panel 517 to receive the main body of the article A.

  The article holding structure 522 in the sixth embodiment is similar to that of the first embodiment. For corresponding members that operate in the same manner as in the first embodiment, the prefix “5” is added to the corresponding reference numerals, and 500 It was shown as a reference sign for the stand.

  In this embodiment, there is no slit because of the orientation of the article. The upper edge of tab 525 is adapted to engage the upper edge of the flange. The tab 525 functions in the same manner as the tab of the first embodiment, and has the same characteristics. The upper edge of tab 525 is offset from fold line 520 or 521. The cuts 526 and 528 define both edges of the tab 525 and also define the edge of the opening 550.

  When assembling the carton from the blank shown in FIG. 14, it is preferable that the carton can be assembled in a straight line machine as shown in FIGS. First, the relative vertical movement between the article and the blank places article A through opening 550, and then, at fold lines 520, 521, the first and second sidewall panels 514, 516 are moved away from the article. It is bent downward so as to be separated, and thereby tilted inward as shown in FIG. The inner and outer base wall panels are then folded inward and secured to the fixed panel 515 in an overlapping arrangement using an adhesive or other suitable means. As a result, a tubular carton is formed as shown in FIGS.

  As shown in FIG. 19, due to the bending process described above, the flange F of the article A protrudes through a part of the opening 550 adjacent to the tab 525 and is engaged by the article holding structure 522b. Set up 525.

  To remove the article from the carton, the end user applies an outward force on the tab 525, thereby releasing the flange F from being held by the holding structure. One or more articles can then be removed from the carton.

  Carton or clip assembly from blanks can be made by a continuous folding operation in a straight line machine, so the carton can be rotated or flipped to complete the assembly of the carton. There is no need to do. The folding process is not limited to the above process and can be modified according to specific manufacturing requirements.

  In addition, terms relating to the orientation of the panel used in the above description, for example, terms such as “top”, “base”, “end”, “side”, “top”, “bottom”, “inside”, “outside” It is not necessarily used to limit each panel to their orientation, but simply a term used to distinguish one panel from another. In addition, the method for realizing the hinged connection in the above description is not necessarily limited to the method using the folding line, but a score line, a frangible line, One or more of the fold lines can be employed.

  It goes without saying that the present invention can be variously modified within the scope of the present invention. In particular, the article holding structure described above is intended to be packaged with various types of cartons, such as wrap-around cartons, top grabbing cartons, adhesives and other known means, with flanges to be held. Can be applied against the required carton. The position of the article holding structure can be set at an appropriate place other than the end of the carton in order to receive the flanged article.
