Definitions

  • the present invention relates to a protective packaging for fragile products such as bottles or jars, a punched blank and a process for making the packaging, and a method for using the packaging.
  • Examples of such internal protective packaging are known for example from WO2015049702 , IT102007901585548 and US6702115B1 .
  • a further problem of the known solutions is that they require large quantities of starting material in order to form the packaging from a punched blank.
  • the technical problem which is posed therefore is that of providing a protective packaging for fragile objects such as bottles and jars, designed to solve or at least overcome the aforementioned drawbacks of the known packaging.
  • a particular object of the present invention is to provide a protective packaging which may be used more easily and rapidly by the end user.
  • the protective packaging should be able to be made on automatic lines in a simple manner from a flat punched blank, by means of an improved process for formation of the packaging.
  • a further particular object of the present invention is to provide a protective packaging of the type described above and optionally an associated container which offer improved protection of the fragile objects so as to prevent damage thereto during transportation.
  • this protective packaging and container should be easy and inexpensive to produce and transport and be able to be easily and quickly assembled for use also by non-specialized users.
  • a protective packaging for fragile objects in particular bottles or jars, according to Claim 1, comprising at least a first housing body for housing one or more fragile objects which is/are formed by a plurality of adjacent planes of a planar punched blank which can be joined and articulated together by means of transverse folding lines for relative rotation and at least one transverse fixing flap glued onto one of said planes, so that the first housing body is movable between a closed position, where it is flattened onto a longitudinal-transverse plane, and an open position, unfolded in the vertical direction Z-Z, where the first housing body assumes a tubular form with a rectangular cross-section.
  • a protective packaging for fragile objects comprising one or more housing bodies having a tubular form with a rectangular cross-section and is provided with one or more openings for inserting a fragile object such as a bottle, wherein one or more of the openings of the housing body is/are closed at least partially by at least one flap, preferably a pair of flaps for each opening, each flap being able to rotate about a respective folding line with respect to the plane of the opening between an at least partially closed position of the respective opening and an open position, rotated towards the inside of the tubular housing body, so as to free the respective opening and form a respective protective flange extending from the plane of the opening towards the inside of the housing body.
  • the one or more protective flanges thus formed which extend in particular towards the inside of the housing body with their free end side, allow the fragile object to be kept in position, if necessary even if the diameter thereof is smaller than that of the opening, and provide increased and gradual lateral protection of the fragile object inserted inside the opening, both when the packaging is intact and when the packaging is subject to gradual tearing owing to the stresses during transportation.
  • An alternative or complementary solution for obtaining improved protection of the fragile objects involves forming a protective packaging comprising an outer plane, arranged in an end position in the longitudinal direction during use of the packaging with the one or more housing bodies in the open position, and feet projecting longitudinally from the outer plane, said feet having a free support edge formed with an undulating profile.
  • the undulating structure of the support feet allows, during the transportation of fragile objects, the force of an impact to be absorbed progressively, and therefore in a gradual and sequential manner, reducing the effects thereof on the said objects, thereby favouring improved protection and reliability of the packaging.
  • the present invention relates furthermore to a planar punched blank for forming a protective packaging according to Claim 12 and a process for forming a protective packaging according to the characteristic features of Claim 18.
  • the present invention relates furthermore to a method of using the packaging for the packaging of fragile objects.
  • the punched blank 100 may for example be formed by a body with one or more layers of corrugated cardboard, the inner and outer surfaces of which situated opposite each other in the direction of thickness Z-Z are formed by a thin lining sheet; the body may be punched using conventional techniques not described here in detail.
  • the punched blank 100 comprises preferably:
  • the outer transverse side of the first plane 110 has, connected thereto, by means of a folding line 112, an end flap 115 provided, on its inner face, with a gluing strip 115a suitable for being joined to the inner face of the central plane 140 in order to fix the first plane 110 to the central plane 140 with the possibility of relative rotation about the folding line 112.
  • the transverse lines 111,112,121,131 which join together, with the possibility of relative rotation, the adjacent planes 110,120,130,140 and the end strip 115 joined to the first plane 110 and fixed to the inner face of the central plane 140 allow the relative articulation of the said planes so as to move the first housing body 1101 from the flattened closed position ( Fig. 2A ) into an open position ( Fig. 2C ), unfolded in the vertical direction Z-Z, in which the first housing body 1101 assumes a tubular form with a rectangular cross-section, the four sides of which are each formed by a respective plane of said four adjacent planes 110,120,130,140 of the punched blank 100.
  • an inner vertical-transverse side 1110 is formed by the first plane 110
  • an outer vertical-transverse side 1130 is formed by the third plane 130
  • the second plane 120 and a part of the central plane 140 form the two longitudinal-transverse sides which are parallel to each other.
  • the first plane 110, the second plane 120 and the third plane 130 therefore form a first set of planes adjacent to each other and connected to the central plane by means of the folding line 131, said planes being designed to form with the said central plane 140 a first housing body 1101 which is movable between a closed position, flattened onto the central plane 140, and an open position where it assumes a tubular form with rectangular cross-section folded out in the vertical direction Z-Z with respect to the central plane 140.
  • the opening movement of the first body 1101 may be easily obtained by means of a simple rhomboid-forming operation, for example by pressing on the outer transverse edge 1121 (formed by the line 121 for folding the second plane 120 with respect to the third plane 130) or for example also by pressing against the outer surface of the third plane 130, so as to move rotationally the first plane 110 and the third plane 130 towards the inside until they are arranged substantially perpendicular to the central plane 140 and parallel to the vertical direction Z-Z.
  • the end flap 115 which joins by means of pre-gluing the first plane 110 to the central plane 140 is preferably fixed to the latter in a position which is on the outside of the tubular body 1101 with rectangular cross-section of the formed packaging 1100, allowing in a particular easy manner the articulation of the first set of planes 110,120,130 with the central plane 140 for closing in the flattened condition or opening in the unfolded condition the housing body 1101.
  • the first plane 110 is provided with a plurality of - for example three - through-openings 113 formed in the vertical direction of thickness of the punched blank and, in the preferred example, aligned in the transverse direction Y-Y.
  • Each opening 113 is designed, once the protective packaging 1101 has been formed, to allow the insertion of a respective bottle 1 in the first housing body I1010 open in the unfolded condition so as to have a tubular form with rectangular cross-section.
  • the openings 113 are in form of circular holes for housing the bottles 1, but may also have different shapes in the case of fragile objects with a different cross-sectional form.
  • the first plane 110 and the third plane 130 directly joined to the central plane 140 by means of the transverse folding line 131 and the fixing flap 115, respectively, are designed to be arranged perpendicularly with respect to the central plane 1140 of the packaging and therefore to a longitudinal axis of each bottle 1, when the housing body 1101 is open in the unfolded condition where it has a tubular form.
  • At least one of said planes 110, 130 of the first set of planes for forming the first housing body I1010 will be provided with one or more though-openings 113 for inserting the fragile objects to be packaged.
  • at least one different plane 1130 of said planes perpendicular to the central plane 1140 which, in the open condition of the housing body, will be arranged in an outer position in the longitudinal direction X-X, will act as an outer (for example upper or lower) support plane 1130 for the packaging 1101 and, for this purpose, will have preferably feet I121a, I131a projecting in the longitudinal direction X-X from the said plane 1130 and preferably formed according to the art known per se by configuring the folding lines 121,131 which connect the third plane 130 respectively to the second plane 120 and to the central plane 140 with two or more discontinuous zones 121a,131a where there are cut-out parts extending towards the inside of the third plane 130, so as to remain coplanar with the respective second plane
  • the central plane 140 has, connected thereto, a second set of adjacent planes 150,160,170 designed to form a second housing body 1102 of the packaging 1101, said planes 150, 160, 170 of the second forming set being also generally rectangular, and connected to the central plane 140 by means of a transverse folding line 141 arranged on the opposite side in the longitudinal direction X-X with respect to the transverse folding line 131 which connects the central plane 140 to the first set 110, 120, 130 of planes.
  • the second set of forming planes comprises:
  • the sixth plane 170 is arranged in an end position in the longitudinal direction X-X and, in a manner similar to the first plane 110, it is joined by means of a transverse folding line 171 to an end flap 175 designed to rotate with respect to the sixth plane 170 about the said folding line 171 and provided with a gluing strip 175 for articulated fixing of the sixth plane 170 onto the inner face of the central plane 140.
  • the second set of forming planes 150, 160, 170 is arranged and configured in a substantially similar and specular manner compared to the first set of forming planes 130,120,110, so that the fourth plane 150 has an arrangement and function similar to that of the third plane 130 and the fifth plane 160 has an arrangement and function substantially similar to those of the second plane 120, so that the planes of the second set are designed to form with the central plane 140 a second housing body 130 which is movable between a closed position, flattened onto the central plane 140, and an open position, where it assumes a tubular form with rectangular cross-section unfolded in the vertical direction Z-Z with respect to the central plane 140.
  • the second housing body 1102 is arranged at an opposite end in the longitudinal lengthwise direction X-X of the packaging with respect to the first housing body 1101 and, situated above it in the longitudinal direction; a suitable distance between the two housing bodies in the longitudinal direction may be set during production based on the longitudinal length of the objects to be packaged, by suitably designing the dimensions of the central plane 140 in the lengthwise direction X-X.
  • the opening movement of the second housing body 1102 may also be easily obtained by means of a simple rhomboid-forming operation, in a manner similar to that described with reference to the first housing body 1101, until the sixth plane 170 and the fourth plane 150 are arranged substantially perpendicular to the central plane 140 and parallel to the vertical direction Z-Z.
  • the end flap 175 which joins by means of gluing the sixth plane 160 to the central plane 140 is also preferably fixed to the latter in a position which is on the outside of the tubular body 1102 with rectangular cross-section of the formed packaging 1100, thus allowing in a particularly easy manner the articulation of the second set of planes with the central plane 1140 for closing in the flattened condition or opening in the form of a rhomboid the housing body 1102.
  • the sixth plane 170 is provided with a plurality - for example three - through-openings 173 formed in the vertical direction Z-Z of thickness of the punched blank 100 and aligned in the longitudinal direction X-X with the through-holes 113 of the first housing body, so as to allow the insertion of a different part for example the neck 1b of the bottle 1 inserted inside the respective opening 113 of the first plane 110.
  • the holes 173 of the sixth plane 170 therefore have a smaller diameter than the holes 113 of the first plane 110, although it will be clear to the person skilled in the art that other dimensions are possible depending on the format of the fragile objects to be transported.
  • the protective packaging 1100 of the present invention formed by the punched blank 100 in Fig. 1 has first and second housing bodies 1101,1102, each movable from the closed position, flattened onto the central plane 140 ( Fig. 2A ), into the open position, unfolded into the form of a tube with a rectangular cross-section ( Fig. 2C ), which allows the end user to be provided with the packaging 1100 in the flattened configuration with the sets of forming planes pre-glued to the central plane already during the production stage.
  • first and second housing bodies 1101,1102 each movable from the closed position, flattened onto the central plane 140 ( Fig. 2A ), into the open position, unfolded into the form of a tube with a rectangular cross-section ( Fig. 2C ), which allows the end user to be provided with the packaging 1100 in the flattened configuration with the sets of forming planes pre-glued to the central plane already during the production stage.
  • each of the packages 1100 may be removed and converted into the configuration with the housing bodies open, as shown in Figure 2C , by means of simple and very quick rhomboid-forming operations, thus resulting in significant simplification and time-saving for the end user without, however, substantially increasing the overall volume of the flattened packaging 1100 with respect to the thickness of the punched blank 100.
  • first and second housing bodies could also be formed as separate protective packages, from respective single punched blanks, and then combined in a container to form a container assembly.
  • the central plane is not necessarily a plane arranged exactly in the centre of the punched blank or the packaging, but indicates a longitudinal-transverse plane of the packaging with respect to which a housing body is flattened or unfolded in the vertical direction.
  • a second embodiment of a protective packaging I200 has a configuration similar to that of the packaging according to Fig. 2C , with a first housing body 1201 and a second housing body I202 which are arranged open in the unfolded condition in the form of a tube with rectangular cross-section and arranged opposite each other in the longitudinal direction X-X.
  • the protective packaging I200 is characterized in that at least the openings 1213 for inserting the bottles 1 of the first housing body are closed at least partially by pairs of flaps I213a separated by a separation line I213b, which may be for example a cut formed in the punched blank 200 or a pre-weakened breakage line.
  • Each flap I213a is designed to rotate about a respective folding line I213c with respect to the associated plane 210 towards the inside of the tubular housing body 1201, so as to open the opening 1213 and allow the insertion of the fragile object to be protected.
  • each flap I213a closes a respective semi-circle of the hole 213 so that the separation line I213b is a diametral line of the hole 213, although other different arrangements of the separation line are possible, such as only partial closures of the opening.
  • the separation line 213b of the punched blank 200 is inclined with respect to the transverse direction Y-Y and the longitudinal direction X-X.
  • each flap I213a is formed along a respective section of the semi-perimeter of the respective semi-opening closed by the flap I213a, in particular a respective circumferential arc in the case of circular holes 213 such as those shown.
  • each opening 1213 is also provided with locking means, in particular in the form of crenellations 1214 projecting towards the inside of the opening 1213 and arranged along the perimeter of the hole 1213, so that the folding line I213c of each flap I213a is preferably included between two of said crenellations 1214.
  • the flaps I213a for closing the openings 1213 are designed to form, once rotated into the open position, respective flanges I213a for protecting the side of the bottles 1 inserted into the respective holes 1213, improving the protection from lateral knocks which are particularly dangerous during transportation and often cause the bottles to hit each other and break.
  • the protective flange I213a once open, is arranged projecting towards the inside of the housing body, with its free end side I213b.
  • the corresponding flange I213a remains connected to the housing body only by means of the respective folding line I213c, while the opposite free side I213b and the perimeter of the flange I213a are not fixed either to the bottom or to other parts of the housing body or the packaging.
  • the flaps 213a which form protective flanges I213a allow an improved protection to be obtained owing to different technical effects:
  • each flap I213a can also be adjusted by means of rotation about the folding line I213a, so that it is possible to correctly keep in position also fragile objects with a smaller diameter than that of the opening 1213 and/or the locking means 1214.
  • An inclined separation line I213b between two flaps 213a of a same opening is particularly preferred since it allows the folding lines I213c of the flaps of a same opening to be arranged not axially aligned with the longitudinal diameter of the opening. In this way the longitudinal distance between adjacent bottles is not reduced and at the same time the two protective flanges I213a are staggered in the transverse direction and occupy a greater transverse space inside the housing body.
  • the packaging according to Fig. 3 is designed to provide better protection for the bottles 1 during transportation.
  • the openings of the second housing body may also be configured with closing flaps movable between a position for at least partially closing the respective opening, coplanar with the respective plane, and an opening position where they allow the insertion of the object through the opening and form respective protective flanges, if required by the shape of the fragile object.
  • the one or more closing flaps may be implemented in any protective packaging for fragile objects comprising one or more housing bodies having a tubular form with rectangular cross-section and provided with one or more openings for inserting a fragile object such as a bottle.
  • a second example of embodiment of a punched blank 200 is configured to form the protective packaging 1200 shown in Figure 3 and comprises a substantially rectangular central plane 240 with longitudinal and transverse sides.
  • a first transverse side of the central plane is connected by means of a transverse folding line 231a to a first set of planes 230, 220, 210 adjacent in the longitudinal direction X-X and connected together by transverse folding lines 221, 211 which allow the relative rotation thereof and are designed to form with the central plane 240 the first housing body 1201 of the packaging I200.
  • transverse folding lines 221, 211 which allow the relative rotation thereof and are designed to form with the central plane 240 the first housing body 1201 of the packaging I200.
  • the first set of planes includes a first outer plane 210 in the longitudinal direction, a second plane 220 adjacent to the first plane 210 and a third plane 230, an outer transverse side of which is connected to the second plane and the inner transverse side of which is connected, by means of the folding line 231, to the central plane 240.
  • the first plane 210 has a transverse end flap 215 joined by means of the transverse folding line 212 to the first plane 210 and provided with means for performing gluing to the inner face of the central plane 240, for formation of the first housing body 1201.
  • the punched blank 200 of this embodiment differs from that of Fig. 1 in particular owing to the presence of flaps 213a for closing the openings 213 of the first plane 210.

  • the punched blank 200 has a set of planes 250, 260, 270 for forming with the central plane 240 a second housing body, similar to those of the punched blank of Fig. 1 and therefore not described in detail.
  • the transverse folding lines 221, 231 and 241, 251 are preferably interrupted by pairs of cut-out regions designed to form projecting feet I231a,I231b for supporting the packaging I200, i.e. end regions 221b in the transverse direction, designed to form corner feet I221b; and inner regions 221a in the transverse direction Y-Y designed to form respective at least two feet I221a projecting in the longitudinal direction X-X from the respective plane 220 once the packaging I200 has been formed.
