FR2821251A1 - Carrying handle for carrier bags is made from folded panel of lightweight material with two apertures and edge-covering flap - Google Patents

Abstract

The carrying handle is made from a single flat panel of a lightweight material, such as cardboard, plastic or leather, with two apertures (f1, f2) and transverse fold lines (b1, b2) enabling it to be folded into a base (B) and two sides (A, C). The cut-away section of one hole is left in place, forming a flap (D) that can be inserted through the other handle to made a double handle with a connecting strip between. A variant of the design has the body of the handle folding into an oval shape with two transverse connecting flaps.

Description

<Desc / Clms Page number 1>

The present invention relates to the production of a load transport handle, formed by self-locking folding of a single flat blank, one of the characteristics of which is to distribute the grip of the handle at two dissociated points, independently of the volume of loads transported. It will also be possible to create, from a part of this same single blank, a flat surface, perpendicular to the forces exerted by the weight of the loads, clearly improving the grip of this handle.

This part grasped by hand will be called here: gripping body.

The part supporting the loads will be called here: carrying area From the same principle it is therefore possible to use it in order to transport: - either loads originally presenting a gripping system of one or more plastic, metal, or twine handles, or any other system generally having one or two more or less concave longitudinal parts, fixed to a volume capable of containing other volumes itself, or attached to or forming part of an object. .) which could lead to bruising of the hands.

- or loads having proportions such that they would present a problem of grasping with bare hands by a person (frame, glass, board, hats, dishes) ...

At the consumer level, the multitude of mass consumption products, as well as the growing evolution of the product ranges sold within the same brand for example, leads to a significant increase in the number of transport bags, and other loads already packaged (with or without a gripping system), necessary for the consumer to bring home his purchases (the bags being, among other things, as a rule quickly limited in carrying capacities). This increase in volume to wear, added to the fineness of the handles for example quickly leads to bruising of the hands, thereby naturally limiting the quantities purchased. At the same time, the increase in the number of bags and other volumes leads to a handling problem during each removal and resumption of the loads carried. The consumer at present can avoid these inconveniences in two different ways: by bringing with him during these purchases a large transport bag or wheeled carts, or else buy on the spot a reinforced bag or a generally sophisticated lifting handle at a relatively high cost This operation is likely to be repeated regularly if he does not think or forget to bring these systems of transport during these next purchases, it will end

 prefer to suffer a little rather than spending a significant amount each time.

At the reseller or distributor level, two new problems appear.

The increase in the number of consumer products in stores leads to a problem of space available on the shelves for the sale of products.

The increase in competition is forcing supermarkets, for example, to constantly improve "customer service" in order to retain them.

If a certain number of patents have been filed to date regarding the best way to carry plastic bags or other loads, they all have a certain number of defects which have slowed down or even halted their industrial development, namely: - those presenting a good grip, but not retaining the handles when placing the loads on the ground, - those at cost far too high for the nature of the services rendered, - those, that! due to their volume make any notion of storage or presentation on the shelf very complicated, - those which do not prevent the transported loads from turning on themselves during transport, thereby making it very difficult to extract one of the loads, for example, those which, due to their shape (cylindrical or linear for example), or their composition (iron, plastic, etc.) cannot bear an advertising or explanatory inscription which does not encourage any distributors to distribute them , and finally, those which are too specific as to the type of load likely to be transported.

The present invention solves all these problems at once
Made by self-locking folding of a single flat blank from a very thin and very light material type: - cardboard with micro-groove laminated or not on heavyweight paper - plastic materials (polypropylene, rubber) - materials natural (leather, sheets) or any other material presenting the same advantages, one of these characteristic is to distribute in two dissociated points the grip of the handle, independently of the volume of loads transported.

The insertion by folding of a flap perpendicular to the thickness of the

<Desc / Clms Page number 3>

 materials used through one of the knockouts necessary for the passage of the hands, makes it possible to achieve a comfortable seat for gripping from a flat element of thin thickness (the gripping body).

indépendant de la partie réservé à l'emplacement de la main, - maintien réunis entre-elles les charges transportées, lors de la relâche de la poignée par l'utilisateur au sol, puisque dés que le pliage du corps de préhension est verrouillé par les encoches de la partie du volet perpendiculaire à la poignée avec l'autre montant vertical, la zone de portage l'est aussi, - pouvant avoir une connotation écologique si l'on utilise, comme dans l'exemple décrit plus loin un carton biodégradable,

- confortable pour la main de part l'absence d'angle vif associé à l'utilisation d'un matériau souple épousant la forme des doigts de la main sous l'effet de la masse transportée, - résistant aux cisaillements provoqués par le balancement du ou des volumes transportées du fait de la superposition d'une ou plusieurs couches absorbantes par écrasement (la cannelure du carton par exemple) associé à une couche résistante à l'étirement (le papier contre-collé pour le même exemple), ou l'utilisation d'un matériaux indéchirable. This folding allows by the use of a double flap from the cutting of the passage of the hand, to close the two parts of the handle: namely the load-bearing area, as well as the gripping body. In addition, this invention has the following characteristics: - easy to store, since it is originally flat, - adaptable to gripping any packaging volume, since the transported volume is located in a part of the handle

independent of the part reserved for the location of the hand, - holding together the transported loads, during the release of the handle by the user on the ground, since as soon as the folding of the gripping body is locked by the notches of the part of the flap perpendicular to the handle with the other vertical upright, the carrying area is also, - can have an ecological connotation if one uses, as in the example described below a biodegradable cardboard,

- comfortable for the hand due to the absence of a sharp angle associated with the use of a flexible material conforming to the shape of the fingers of the hand under the effect of the mass transported, - resistant to shearing caused by the rocking of the or volumes transported due to the superposition of one or more absorbent layers by crushing (the fluting of the cardboard for example) associated with a layer resistant to stretching (the laminated paper for the same example), or the use of a tear-resistant material.

- prevents swirling of the transported loads due to the length of the carrying area - easy to carry out since an assembly diagram can be indicated above (the latter becoming invisible when the handle is shaped), - reusable, thanks to a system of blocking notches making it possible to open and close at will, - inexpensive because of its composition, thus allowing repeated acquisition at lower cost, - comprising at least 3 visible faces capable of receiving colors and / or inscriptions advertising or informative for its retail or promotional dissemination; as well as a number of hidden faces on

<Desc / Clms Page number 4>

 which can appear any type of inscriptions such as for example, cooking recipe, games, promotions, poems, drawings ...

 The cutouts for the passage of the hand or fingers, may have different shapes more or less rounded, more or less wide, in order to improve for example the aesthetics, comfort, or the cost of production.

 The blocking notches can be reinforced by male pins which are introduced into notches at the level, for example of the cutouts reserved for the passage of the hand, in order to improve the blocking of the handle or any other blocking system based on notches or tabs.

fermeture de la poignée permettront la réalisation par exemple de poignée inviolable garantissant la non ouverture de la poignée, ou encore d'accroître la qualité de la fermeture de la poignée. Adhesive tapes, repositionable or not, added to the shutters used for the

closing the handle will allow the production, for example, of a tamper-resistant handle ensuring the non-opening of the handle, or even increasing the quality of the closing of the handle.

Regarding large loads, the principle remains the same except that the two vertical uprights under the space reserved by hand, are larger in length in order to fit the object or objects supported while protecting them . The carrying area being proportional to the width of the loads transported. In order to prevent the transported load from going out through the lateral vents of the lower part of the handle, the external vertical uprights may have at their peripheries the necessary number of legs and blocking slots (placed in such a way that after folding the vertical uprights, one leg is found symmetrically opposite a slit. If the load transported is relatively thick, a blocking lug and its slit (recovered by smashing in the flat area) placed symmetrically and respectively on each of the vertical uprights will be added on the vertical uprights under the space reserved for the passage of the hand. In this case, new folding grooves will be placed symmetrically on all the vertical uprights in order to conform to the shape of the product transported. If the load transported has a convex shape , a double vertical and horizontal grooving, with regular spacing of the lower part of the uprights s vertical will improve the resistance of the product (s) being transported. The installation of flap flaps and slots and self-locking tabs in order to close the side vents is also possible.

The accompanying drawings illustrate the invention: FIG. 1 is a plan view, flat, of a blank intended for the production of a

<Desc / Clms Page number 5>

 handle carrying bag handles according to the invention.

FIGS. 2, 3 are respectively the folded handle seen from the front, the folded handle seen in profile obtained by folding the blank illustrated in FIG. 1.

Figures 4 and 5 schematically show in section and in perspective variants of handles adaptable more specifically to other types of loads.

laquelle un certain nombre de lignes de pliages réalisés par rainurage (b2, b1, dl, d2), comporte successivement : - une suite d'au moins trois volets (A, B, C) avec des lignes de pliages propre à former une structure pyramidale par pliage (b1, b2) (figure 2). L'ordre des volets se succédant ainsi. Le premier volet (A) possède une découpe suffisamment large pour permettre le passage des doigts d'une main (f1), il constituera un des montants vertical gauche, suivi du deuxième volet (B) qui lui aura pour rôle de soutenir les charges portées (zone de portage), puis le troisième volet (C) (inversement symétrique au volet (A) par rapport à un axe horizontal) possédant également une découpe pour le passage de la main (f2) (montant vertical droit). As can be seen in FIG. 1, the handle is composed of a single blank cut from a thin material of thick polypropylene type, laminated cardboard or other semi-rigid material. This cut, on

which a certain number of fold lines produced by grooving (b2, b1, dl, d2), successively comprises: - a series of at least three sections (A, B, C) with fold lines suitable for forming a structure pyramid by folding (b1, b2) (Figure 2). The order of the flaps succeeding each other thus. The first flap (A) has a cut wide enough to allow the passage of the fingers of one hand (f1), it will constitute one of the vertical uprights left, followed by the second flap (B) which will be responsible for supporting the loads carried (carrying area), then the third flap (C) (inversely symmetrical to the flap (A) with respect to a horizontal axis) also having a cutout for the passage of the hand (f2) (upright upright).

Ce volet (D) se divise en 2 parties (e1, e2) La partie (e1) du volet D, a pour rôle d'offrir une surface plane aux doigts favorisant la répartition des charges supportées. Des encoches (g1, g2), par exemple, réalisées à la périphérie droite et gauche de ce volet (e1) permettent la fermeture de la poignée par encastrement dans les encoches (h1, h2) de la découpe (f1). The cutout (f1) has a system of notches (h1, h2) suitable for blocking the part (e1) of the shutter D - a shutter (D), part preserved from the cutout f2, comprising at least two folds (d1, d2 ) will be used to produce the perpendicular part of the handle under which the fingers of the hand will come to rest (the gripping body) (e1), on the other hand to ensure the closing of the handle (e2)

This shutter (D) is divided into 2 parts (e1, e2) The part (e1) of the shutter D, has the role of offering a flat surface to the fingers favoring the distribution of the supported loads. Notches (g1, g2), for example, made on the right and left periphery of this flap (e1) allow the closing of the handle by embedding in the notches (h1, h2) of the cutout (f1).

réservée au passage de la main (f1) (figure 2 et 3) traverse la découpe (f1), puis ressort en longeant vers le haut le volet (A) afin que la ligne de pliure (d1) se trouve en contact avec le montant A. Cette partie (e2) a pour but d'améliorer la prise en main de la poignée. The part (e2), with a width less than or equal to the width of the cutout

reserved for the passage of the hand (f1) (FIGS. 2 and 3) crosses the cutout (f1), then comes out, going upwards along the flap (A) so that the fold line (d1) is in contact with the upright A. This part (e2) aims to improve the grip of the handle.

The flap (B), or even the carrying area between the two vertical uprights, which supports the loads by means of the handles for example

<Desc / Clms Page number 6>

 may be more or less wide, or more or less long in order to best adapt to the shape of the loads supported. Due to its length, it prevents the supported loads from turning on themselves during transport, which significantly improves walking comfort on the one hand and the extraction of loads on the other.

To adapt the handle to large loads, the principle remains the same except that it will be necessary to widen and / or enlarge the parts (0) and (P) of the two vertical uprights (A, C) so to marry the object or objects supported while protecting them. The carrying area B being proportional to the thickness of the loads transported (Figure 3). The addition of horizontal and vertical fold lines will allow the parts (O, B, P) to marry all types of volumes, flat spherical or asymmetrical (Figure 4).
