Definitions

  • the present invention generally relates to packing protectors suitable for protecting packed fragile objects such as appliances, computer parts etc. commonly shipped in a box. More particularly, it relates to a packing protector formed from elongated strips of material.
  • Packing protectors of different types are already commonly used to protect fragile items, such as appliances, computer parts, etc., during their shipment.
  • U.S. Pat. 4,883,179 discloses a packing member formed from an expanded plastic foam sheet.
  • the packing member is formed by dividing the sheet into two legs by a V-shaped longitudinal groove. The surfaces of the foam sheet defining the V-shaped groove are coated with an adhesive to keep the packing member in shape once folded.
  • U.S. Pat. 4,888,179 and 5,024,328 in the name of Bontrager disclose a packaging frame formed from a blank including interior cuts and minimal cutouts. The blank is operably shifted to and form a single piece frame having an exterior quadrilateral to interfit with the interior of packing containers and having an interior perimeter to accommodate the reception of a part for shipment. Once removed from the container, the packing member disclosed by Bontrager goes back to its original unfolded state since there is nothing provided to keep the packing member in its folded shape. Other examples of packing protector are given in US patents nos.
  • An object of the present invention is to propose a packing protector that will satisfy these above-mentioned needs.
  • a packing protector formed from an elongated strip of flexible cushioning material, the elongated strip having a cross section including an L-shaped portion defining a vertical wall and a horizontal wall.
  • Each of the horizontal wall and vertical wall has an inner side surface opposite an outer side surface and the strip comprises at least one transversal folding line allowing the strip to be folded to form the packing protector.
  • the folding line is formed by a groove spanning transversally on the inner side surface of the vertical wall.
  • the groove is associated with a generally V-shaped folding cutout in the horizontal wall shaped to form two matching surfaces which are brought adjacent to each other when the strip is folded, thereby forming a unified wall.
  • One of the two matching surfaces includes a male coupling interiockable with a female coupling in the other matching surface to keep the strip once folded in the form of the packing protector.
  • the male coupling preferably consists of a tooth-like projection projecting from the matching surface and the female coupling preferably consists of a cavity shaped to receive the tooth-like projection and thus form a joint.
  • a packing protector according to the present invention has the advantage of being easy and simple to ship to the user or purchaser in great amounts as the unfolded strips can be easily piled up for the delivery. And once it is ready to be used, the strip has the advantage of being very easy and simple to be folded into the shape of the packing protector, and thanks to the male and female coupling, the packing protector remains in shape once folded without requiring any other tool or adhesive material.
  • Figure 1 is a perspective top view of a packing protector according to the present invention having the shape of a partly bottomless box.
  • Figure 2 is a top view of the packing protector of figure 1 shown in partially folded state.
  • Figure 3 is a top view of the elongated strip of material used to form the packing protector of figure 1.
  • Figure 4 is a cross-sectional side view of the strip shown in figure 3, which is taken along line IV-IV.
  • a packing protector (10) may have the shape of a rectangular box. However, it may take a lot of other shapes such as a simple corner protector or any other polygonal shape as a triangle, a heptagon, hexagon etc.
  • the packing protector (10) is formed from an elongated strip (12) of flexible cushioning material, which is preferably a plastic foam material such as polypropylene and polyethylene.
  • This elongated strip (12) has an L-shaped cross section defining a vertical wall (14) and a horizontal wall (16), each having an inner side surface (18) opposite an outer side surface (20).
  • the strip (12) comprises at least one transversal folding line (22) allowing the strip (12) to be folded to form the packing protector (10).
  • the preferred embodiment illustrated comprises four of those folding lines (22).
  • a packing protector according to other embodiments of the invention may have more or less than four folding lines depending on the shape desired. For example, a simple corner protector would only have one folding line and a U-shaped protector would have two folding lines.
  • each folding line (22) is formed by a groove (24) spanning transversally on the inner side surface (18) of the vertical wall (14).
  • This groove (24) is associated with a generally V-shaped folding cutout (26) in the horizontal wall (16).
  • This cutout (26) is shaped to form two matching surfaces (28A, 28B) which are brought adjacent to each other when the strip (12) is folded, thereby forming a unified wall (30), as shown in figure 1.
  • the groove (24) is preferably fan-shaped and disposed at the tip of the V-shaped cutout (26), as best seen in figure 3.
  • one of the two matching surfaces (28A) defined in the horizontal wall (16) includes a male coupling (32) interiockable with a female coupling (34) in the other matching surface (28B).
  • the male coupling (32) may preferably consist of a tooth-like projection projecting from the matching surface (28a) and the female coupling (34) then consists of a cavity shaped to receive the tooth-like projection (32) and thus form a joint.
  • the strip (12) is folded at the folding lines (22), then the strip (12) is twisted or bent in order to insert the tooth-like projection (32) into the cavity (34).
  • the formed protector (10) thus remains in shape.
  • the V-shaped folding cutout (26) of the folding lines (22) has an opening angle ( ⁇ ) of 45°, as indicated on one of the cutouts (26) illustrated in figure 3, such that the packing protector (10) has the shape of a square corner at the folding lines (22).
  • Different shapes of packing protectors according to the present invention may be obtained by varying the opening angle of the V-shaped cutout (26).
  • the strip (12) comprises at least three folding lines (22) dividing the strip (12) into a plurality of sections including a right end section (36) opposite a left end section (38) and at least one middle section (40) therebetween, as indicated in figure 3, and the V-shaped folding cutout (26) of each folding line has an opening angle ( ⁇ ) calculated so as to allow the end surface (42) of the right end section (36) and the end surface (44) of the left end section (38) to join up when the strip (12) is folded at each folding line (22).
  • the preferred embodiment illustrated which has the shape of a square box, contains three of those middle sections (40) having the same length (L).
  • the packing protector formed with such a strip (12) has the shape of a square box.
  • the strip (12) preferably comprises a connecting means to securely connect the right end section (36) with the left end section (38).
  • the connecting means preferably comprises a tenon-like projection (46) formed at the end surface (42) of the right end section (36) and interiockable with a mortise-like cavity (48) formed at the end surface (44) of the left end section (38). Both the tenon-like projection and the mortise-like cavity preferably have a T shape.
  • the cross section of the strip (12) may be U-shaped, thereby defining one vertical wall and two horizontal walls.
  • the groove of each folding line would be associated with a V-shaped cutout formed in each of the horizontal walls.
  • the necessary shape of a strip (12) according to the present invention may advantageously be cut by a hot wire process or any other known method used to shape plastic foam materials.

Abstract

L'emballage (10) protecteur décrit dans cette invention est formé à partir d'une bande (12) allongée en matériau de calage flexible présentant une section transversale en L qui définit une paroi (14) verticale et une paroi (16) horizontale. Cette bande (12) comporte des lignes (22) de pliure transversales permettant de la plier afin de former l'emballage (10) de protection. La ligne (22) de pliure est formée par une rainure qui s'étend sur la surface intérieure de la paroi (14) verticale dans le sens transversal. Cette rainure (24) est associée à un évidement (26) de pliure en forme de V ménagé dans la paroi (16) horizontale, formé de manière à présenter deux surfaces (28A, 28B) complémentaires qui se trouvent dans une position adjacente l'une à l'autre lorsque la bande (12) est pliée et forment ainsi une paroi unifiée. Une ou deux de ces surfaces (28A) complémentaires comprennent un élément (32) d'accouplement mâle qui vient se verrouiller avec un élément (34) d'accouplement femelle se trouvant sur l'autre surface (28B) complémentaire pour que la bande (12) pliée garde sa forme d'emballage protecteur. L'avantage de cet emballage (10) protecteur est qu'il peut être expédié facilement en grandes quantités à l'utilisateur ou à l'acheteur, les bande (12) non pliées pouvant être facilement empilée pour l'expédition. En outre, au moment de son utilisation, il est très simple de plier cette bande (12) et de former ainsi un emballage (10) protecteur.
