Description

M¬ CARRIER ENVELOPE WITH FINAL SECTIONS DESCRIPTION OF THE INVENTION This invention relates to an envelope type carrying article that accommodates a plurality of 5 similar primary containers such as boats or parallelepiped packs (commonly referred to as "blocks"). The carrier article includes end sections to hide coded information present in the individual items at each end of the carrier thus, the code carried by a simple article is not read or registered when the code is required by the carrier article itself. In particular, the invention provides a wrap-around cardboard box for blocks which are wrapped from the base. To provide the code covering the sections for the ends of the cardboard box, the sections are cut from the base (or as may be the case from the top) and the side walls. Optionally, the sections of covers are used to retain the items inside the cardboard box. 20 It is known to create a "large" model by means of bent sections formed from other sections in an overlaid form. For example, US 3 083 891 illustrates stretches taken from the side walls of the folding cardboard box as well as extending the base wall of the box. cardboard so they allow to use a small model.

Also to form codes that cover stretches from an inner portion of the model and to bend them in position.

US 5 381 891 (Harris) shows such a cardboard box in which the sections are connected by bending lines to the side walls of the cardboard line. A problem associated with the prior art is that code which covers the sections that must be formed before the model is applied and the part of the upright cardboard box must therefore be formed and then pulled on top of the cans. To increase the packaging speed, a cardboard box is preferably wrapped from the base, ie the articles are placed in a cardboard box and the cardboard box is wrapped. This method of construction of the cardboard box is made by folding the lateral sections and the especially complicated end sections. The present invention and its preferred embodiment seek to achieve or at least mitigate the problem associated with the prior art. The folding operation is simplified since in some cases the model remains flat while the contents of the cardboard box are placed on it. One aspect of the invention is to provide a cardboard box having base sections, an upper part and lateral sections that are interconnected for. forming a tubular structure for packing a group of articles, for example, in parallelepiped portions, the carton comprises an end section for traversing one end of the tubular structure and striking from and connected to one of the upper or base sections, the The end section has a neck portion and a portion of the band that are adapted to be bent so that the neck portion is connected to the upper part or, as the case may be, the inner surface of the base, and wherein the portion the band extends through one end of the adjacent tubular structure, the articles furthest away at the end of the carton. According to an optional feature of this aspect of the invention, the end section may cover that portion of the article that includes the bar code information. According to another optional feature of this aspect of the invention, the end section can be partially hit from at least one side of the section to define a tab that connects that of the side section when the end section is in use. According to another optional feature of this aspect of the invention, the end section may be adapted to retain adjacent articles within the carton. Another aspect of the invention provides a model for forming a wraparound carrier comprising a series of upper section, the first lateral section, the base section and the second lateral section connected in the form of a hinge one to the nearest and where an end section is struck from one of the upper or base sections, the end section has a portion of neck and an end band, wherein the neck portion is positioned adjacent the edge of the face of the upper or base leg and hinged to the upper or base leg by a fold line at the base of the neck portion extending substantially between the first and second side walls. According to an optional feature of this invention, the end band can be struck from at least one of the side sections to define a tongue which is in use connected to that side section. Another aspect of the invention provides a method for producing a carton substantially above described, which method comprises setting out the model in the flat condition and folding each of the end section out of the plane of the base section and towards the free edge thereof. so it places the neck portion in a face-to-face relationship with the inner surface of the base or upper section so the band is arranged along the rest of the model; load the articles in said base section; folding the strip portion out of alignment with the neck portion and in a substantially perpendicular relationship with the base section and adjacent most of the articles in the base section; fold said side walls and the top wall and connect it to it to form a complete cardboard box. Preferably, the band has bending tabs connected to the opposite ends of the band, and the method further comprises the step of adhering each of the tabs at the sides. One embodiment of the invention will now be described by means of examples only, with reference to the accompanying drawings in which: Figure 1 is a plan view of a model for forming a carrier article according to the invention; Figure 2 is a perspective view of the model illustrated in Figure 1; Figures 3, 4 and 5 illustrate several stages during the establishment of the end sections of the invention; and Figure 6 is a perspective view of the carrier article formed from a model illustrated in Figure 1. With reference to the drawings and in particular to the Figure 1 thereof, a cardboard box model 10 is shown to form a carrier article made of cardboard or similarly foldable sheet material. The model 10 comprises a series of upper sections 12, a lateral section 14, a base section 16, a second lateral section 18 and engageable adhesive tabs 20 connected one to the next along the fold lines 22, 24,26 and 28 respectively. The cardboard box is used to pack a plurality of items, for example, "block style" primary containers. The blocks are coupled in three rows of three blocks, but this is conceptualizing the invention that can be applied to any number of items, coupled in different ways. As shown in Figure 1, the first end portion 30 is struck from the base section 16 while being unbalanced on one of the sides and hingedly connected thereto by the fold line 32. The bending line 32 is substantially parallel to and spaced from the end portion 34 of the base portion 16. The end portion 30 comprises in series a neck portion 36, the intermediate section 38 and the end band 40 extending out of the end edge 34. The neck portion 36 connects bent to the base of the section 16 along the fold line 32. The intermediate section 38 is connected bent to the neck portion 36 along the fold line 39 which, in this embodiment, is disposed opposite to the fold line 32. The intermediate section 38 is substantially trapezoidal in shape. The end band forty is connected in a folded form to the intermediate section 38 along the fold line 42. In this way, the neck portion 36, the intermediate section 38 and the end band 40 are connected in a fold together series. In some modalities, an intermediate stretch is not required. It is conceptualized that the particular shape of the intermediate section 38 is not restricted to the shape illustrated in FIG. 1. The end strip 40 extends between the fold lines 24, 26 to define a pair of oppositely disposed side edges. The tab 44 is struck from a portion of the side section 14 and hingedly connected to one of the side edges of the end band 40 by the fold line 46. In this embodiment, the fold line 46 is in an extension of bending line 24 interrupted. Likewise, the locking tongue 48 is struck from a portion of the side section 18 and is hingedly connected to the opposite lateral edge of the end band 40 being connected in a hinged manner to it by the fold line 50. The fold line 50 is an extension of the bend line 26 interrupted. A second end section 60 is struck from a base section 16 and is substantially identical to the first section end being in a reflection image about a central longitudinal axis. The end section 60 is hingedly connected to the base section 16 by the fold line 62 which is substantially parallel to and spaced from the end edge 64 the base section 16. The end section 60 comprises a neck portion 66, the intermediate section 68 and the end band 70 extending outward from the end edge 64. The neck portion 66 is hingedly connected to the base section 16 along the fold line 62. The intermediate section 68 connects in the form of a fold to the portion of neck 66 along fold line 69 which, in this embodiment, is disposed opposite to bend line 62. Intermediate section 68 is substantially trapezoidal in shape. The end band 70 is connected in the form of a bend to the intermediate section 68 along the fold line 72. In this way, the neck portion 66, the intermediate section 68 and the end band 70 are hinged together in series. As shown in Figure 1, the end band 70 extends between the fold lines 24 and 26 to define a pair of side edges arranged in an opposite manner. The tongue 74 is struck from the side part portion 14 and hingedly connected to one of the side edges of the end band 70 along the fold line 76. In this embodiment, the fold line 76 is in an extension of the interrupted bending line 24. Likewise, the locking tab 78 is struck from a portion of the side portion 18 and hingedly connected to the opposite side edge of the end band 70 being hingedly connected thereto by the fold line 80. The fold line 80 is in an extension of the interrupted bent line 26. The free edges of the side sections 14 and 18 are formed to provide portions of a reduced width. The construction of a complete carrier shown in Figure 6 from a mold requires a series of sequential bends and gummed operations. The bending process is not limited to that described in the following and may be altered according to the particular manufacturing requirements. The bending process is illustrated in Figures 2 to 5, whereby a mold is supplied to the packaging machine in a flat condition illustrated in Figure 2. The end portions 30 and 60 move out of alignment with both sections lateral and base 16; 14 and 18 respectively. The end section 30 is bent 180 degrees inward of the base section 16 approximately the fold line 32 such that the neck portion 36 retracts into a contacting face in overlapping relationship with an inner face of the base section 16 adjacent the end edge. 34. Likewise, the end section 60 is bent 180 degrees inward of the base section 16 approximately the fold line 62 and the neck portion 66 is brought into a contact face in overlapping relationship with the portion of the base section 16 adjacent to the end edge 64, as shown in Figure 3 those end sections 30-60 that can be folded inward are hinged instead of those neck portions that are in contact with an end face of the base section 16. In this embodiment , 6 blocks are placed in the base section 16 and the cardboard box is built around the articles. An advantage of the introduction of articles at this stage in the bending process is that this greatly simplifies the bending operation since the model remains flat while the contents of the carton are placed in it. However, those items that can be stacked in the model in the later stages are hinged if desired. The model is then bent into a condition of the upright part illustrated in Figure 4, thus, the intermediate section 38 is bent out of alignment with the neck portion 36 around the bent line 39 and in a substantially perpendicular relationship with the section. base 16. Thereafter, the end band 40 bends out by 180 degrees approximately to the fold line 42 and in face-to-face relationship with the intermediate portion 38. Likewise, the intermediate portion 68 is bent out of alignment with the portion of frame 66 around the fold line 69 and in a substantially perpendicular relationship with the base section 16 and the end band 70 is bent outwards by 180 degrees around the fold line 72 and in a face-to-face relationship with the section intermediate 68. Thereafter, the connecting tab 44 is bent in a substantially perpendicular relationship with an end band 40 around the fold line 46 and the tongue 48 is folded around the middle. e the fold line 50 and in perpendicular relation with the end band 40. The opposite end section 60 is constructed in a similar manner whereby the tabs 74 and 78 are folded around the respective bent lines in a perpendicular relationship with the end band 70 as shown in Figure 5. In addition, the side sections 14, 18 are bent out of alignment and in a perpendicular relationship with the base section 16. The lateral section 14 is brought in face-to-face relationship with the tabs 44 and 74 and interconnected by an adhesive or other means known in the art. The side portion 18 is attracted in face-to-face relationship with the tabs 48 and 78 and connected together by the adhesive or other means known in the art. The upper section 12 is folded around the fold line 22 and the adhesive tab 20 is bent towards the fold line 28 in an overlapping relationship with the upper section 12 and connected together by adhesive or other means known in the art. Thus, the carton is in an established condition as illustrated in Figure 6. The articles are retained within the carrier by the end bands 40, 70. The intermediate sections are used to provide a multiple layer to increase the integral strength of the band. Optionally, the intermediate sections and the end bands adhere together. The position of the band relative to the base section can be altered according to the position of the bar code information in the individual blocks. When the individual blocks are removed from a carrier after the purchase, a user can grasp an individual block more easily because the lateral sections reveal a side portion of the more distant blocks. The shape of the model allows efficient use of the board to achieve, in this way, the need for the complex structure is reduced with a consequent saving in the cardboard. In addition, the construction of the cardboard box can take place during the loading of the bottle that accelerates the loading process. The present invention and its preferred embodiment still relate to a carrier article that is formed to provide satisfactory strength to hold the secured articles only with a degree of flexibility so that the load transferred from the legs is absorbed by the carrier. The carrier can be applied in an order of items, but manual or automatic machinery. It is anticipated that the invention can be applied to a variety of carriers and does not limit those of the wrapping type.
