IMPROVED PACKAGING The present invention relates to an improved packaging. In particular, the present invention relates especially, but not exclusively, to a package for use with a door for a household electrical appliance such as, for example, a refrigerator or freezer. In order to prevent the penetration of external air into the refrigerator cabinet, the technique of providing a seal between the refrigerator door and the cabinet is known. The refrigerator door generally comprises an internal door part and an external door part, which are coupled together through a suitable device. In general, to provide the seal, a package is provided that fits against the inner door portion of the refrigerator door and provides a seal between the package and the inner door portion, thereby preventing the penetration of external air into the container. The gabinet. The package is usually fixed on the internal door part of a refrigerator, the inner door part has a profile along one or more sides of groove type that acts to receive an anchor part of the packaging which facilitates its fixation. In order to achieve an airtight seal between the refrigerator door and the cabinet, it is also known to provide the package with a magnetic insert which makes contact with a suitable metal strip located in the refrigerator cabinet, and by virtue of the magnetic attraction generated a seal by keeping the refrigerator door closed. In this way, the packaging itself and the metal strip act together to prevent the penetration of external air into the refrigerator cabinet. With reference to Figure 1 of the accompanying drawings, a diagram of a typical package for a reflector door is presented through the reference numeral 1. The refrigerator door 2 comprises an internal door part 4 and an external door part 3. The internal door part 4 has a slot 6 around its perimeter, where a part of the packaging 1 is located. When the refrigerator door is closed, the package 1 around the perimeter of the refrigerator door is in contact with the cabinet 5 of the refrigerator. In its operative position on the external door part 4, the packing structure 1 takes the position indicated by the dotted lines. In its non-operative position, that is, before closing the door, the package 1 takes the position indicated by the solid lines. The package 1 is made of a soft material, such as a polymer, and comprises an upper part 7 having a base 8, and a fixing device 9. The upper part 7 comprises a chamber 10 for a magnetic insert 11. A The sealing pad 12 rests against the inner door part 4, and thus prevents the penetration of external air into the domestic appliance. Seal bellows 13 rest against the external door part 3 and therefore prevent the penetration of external air into the household appliance. The fixing device 9 has a shape such that it can be held releasably in the slot 6 in order to fix the package 1 on the refrigerator door 2 in the inner door part 4. The profile of the fixing device 9 it is elongated, having three prongs substantially vertically oriented 14, 15 and 16, where the prongs 14 and 15 are on the opposite side of the fixing device 9 relative to the prong 16. The prongs 15 and 16 are pushed outwardly between them to form an arrow. When the fixing device 9 is in its operative position (as illustrated), the fingers 15 and 16 are deformed and pushed against the inner walls 17 and 18, respectively, of the slot 6, in order to hold releasable the package 1 in place in the refrigerator door 2. The slot 6 has a shape such that a narrow opening is defined in its inlet 19, which facilitates the fastening of the package 1 within the slot 6 by the tines 14, 15 and 16. However, there are numerous disadvantages associated with the use of a package 1 of the type illustrated in Figure 1. For example, most of soft polymers suffer from plastic deformation, that is, when they are compressed for a certain period of time they lose their ability to recover their original shape after the removal of the compression force. This results in the retention force of the clamping device 9 in the groove 6 decreasing over time, which can result in the removal of the packaging of the door of the refrigerator 2. Also, the capacity of retention of packaging and sealing they depend on the flexibility of the material. It is generally difficult to increase the retention of the packaging by reducing the flexibility of the material without adversely affecting the sealing capacity. In addition, due to the flexibility of the material, which is a compromise between sealing and retention properties, the packaging is easily damaged and difficult to install. In addition, the fixing device 9 can tolerate only minor changes in the width of the groove, and consequently, the groove 6 must be formed in a precise manner and the width of the groove must be precisely controlled. In addition, the fixing device 9 requires relatively wide tolerances in the welded structure due to the inherent flexibility of the soft material from which it is made. International Patent Publication No. WO 00/28267 discloses a similar package for a refrigerator having a profiled external door. The package comprises a fixing device which is located in a perimetric groove around the external door part, a sealing strip, a bellows-like portion, and a base from which the fixing device extends. The sealing strip and the bellows-type portion are made of a soft plastic material, to provide a seal, while the base of the packaging is made of a rigid plastic material, which can be co-extruded with the soft plastic portions of the packing. The fixing device incorporates a flat part which is in contact with the base and the flat part has an end which is bent upward towards the bellows-like portion to form an oblique part. The packing attachment device includes a rigid central leg having several rigid prongs extending therefrom, whereby the prongs have cushions of soft material at their ends which are in contact with the inner walls of the slot with the object to retain the package on the external wall part. The rigid base and the oblique part improve the rigidity of the packaging in the front wall. There are numerous disadvantages related to the use of a package having such a fixing device. For example, the conflability of the seal is reduced because the package has a tendency to "climb" on the internal walls of the groove in the outer wall portion due to the cushions of soft material. Furthermore, the resulting inflexibility of the shape of the fixing device results in the fixing device being able to tolerate only minor changes in the width of the groove in the external door part. Accordingly, it is necessary to precisely control the width of the groove in the outer door in order to provide an adequate seal. An alternative package is also disclosed in WO 00/28267, which includes the same oblique portion, but which includes a fastening device having a single leg in the form of a rigid hook, with several soft prongs extending from opposite sides of the body. the same. The elbow part of the leg is made of a soft material and in this way the elbow part of the leg acts as a living hinge to effect the insertion of the leg into the groove. Nevertheless, there are several disadvantages associated with the use of a gasket of the type incorporating said fastening, not only the fact that the ability of the single hook-shaped leg to retain the gasket in place decreases with the passage of time, due to the effects of plastic deformation of the soft joint segment of the leg. In addition, the soft tines allow the package to "lift" on the internal walls of the slot, potentially causing the package to come loose from the groove of the outer door part. EP 0 319 087 describes a package contemplated for use in refrigerator doors. The structure is similar to the structures described in the prior art documents cited above, except for the fastening device that includes a single upwardly bent leg having a soft elbow. The end of the leg has a configuration such that it engages an edge of an external wall part and is slidably located in a space between the base of the fixing device and the external door part. In this way, the fixing device acts as a spring in order to provide a snap fit with the external body part to releasably hold the package in place in the refrigerator door. However, there are numerous disadvantages related to the use of a package of this type, not only the fact that the package must be assembled in the inner door part before effecting the "foam application" on the door. This results in the fact that the package is subjected to high temperatures and significant compressive forces, which combine to deform the package and reduce its sealing efficiency.
It is generally desirable that the cut of the inner door portion be accurate, and the packing structures do not allow large variations of internal door portion size. Furthermore, it is desirable that the internal door parts have a straight and uniform cut, since irregular and uneven internal part edges prevent a correct fit which can cause a foam leak. This can result in inadequate doors for use in production. In addition, due to the spring action of the retaining leg, the packing can be easily removed from the inner door part which causes leakage of foam and doors unsuitable for use in production. Finally, after foam placement, the package now forms an integral part of the door assembly. In the case where it is necessary to replace the packaging, a custom-made replacement packaging is required that, by nature, requires custom-made production tooling at an additional cost. There is a need for a package that does not have the disadvantages indicated above or at least mitigates said disadvantages. According to the present invention, a package for household appliance having a door and a cabinet is provided, the profile of the package comprises a bellows-like section that can form a seal between the door and the cabinet, and a fastener manufactured from a rigid material fixed on the bellows-type section, said fastener is suitable for fixing the package on the door, wherein the fastener comprises a part of the fastener for placement in a formation in the door, and a fastening device for fixing the fastener on the bellows-type section, said fastening part comprises two independent and resiliently deformable independent legs, each leg is fixed on one end of the fixing device and is bent on itself at the other end for a direct engagement with the formation on the door. In a preferred embodiment of the invention, the fastener part is made of a rigid polymeric material. The fastener part can be manufactured, for example, from rigid unplasticized thermoplastic material, excluding elastomers. For example, the fastener part can be made of PVC-Ü (unplasticized PVC), polypropylene, polyethylene, ABS or polystyrene, however, it will be appreciated that any suitable rigid material can be used. The legs are bent over towards the outside to allow a sufficient foot length for maximum compression capacity of the fastener part. For example, each leg has a hook-up free end. This allows an easy insertion in the formation and allows adapting to variations in the width of the groove. The ends of the legs do not have parts of soft plastic material and consequently the rigid legs engage directly with the groove. This helps prevent the fact that the package "goes up" by the internal parts of the formation, which can potentially result in the removal of the package. The legs engage the slot at an acute angle relative to the vertical and therefore act as a cam against the internal wall of the formation, since the approach to the opening of the formation is narrower than the base of the formation. In this way, when a gasket must be fixed on the door of a refrigerator, the free ends of the legs are pushed together when in contact with the narrow entry of the groove. In this way, the fastener is allowed to pass in the groove formation. When pushed together within the groove, the legs are pressed outwardly relative to each other, such that they separate when they are inside the formation to engage the opposite inner walls of the formation and provide a gripping action due to the equal and opposite forces applied by the respective legs on the opposite inner walls and consequently to maintain the packing on the door of a refligerator. The profile of the fastener part can be continuous over the length of the package. Alternatively, the profile of the fastener part is discontinuous along the length of the package, whereby several discrete fastener portions spaced over the length of the package are provided. Preferably, the bellows-type section is made of a mild polymeric material. The bellows-type section can be manufactured, for example, from plasticized thermoplastics, such as soft PVC, or elastomers such as SRT (synthetic rubber thermoplastic), TPE, or PUR. However, it will be noted that any suitable mild polymer can be used. Preferably, the bellows section comprises an upper part, a base, and the fastener is fixed on the base of the bellows-type section. It is preferable that the base of the bellows type section includes a profile defining a hollow chamber. When the package is in its operative position, the profile defining a hollow chamber comes into contact with the external door part, to provide a means to prevent the penetration of external air between the external door part and the package. It is preferable that the fixation device is made of a rigid polymeric material and comprises a substantially planar planar member wherein the planar member is fixed on the bellows-like section to effect a fixation there. Advantageously, the fastening device and the fastener part can be integrally formed. Preferably, the substantially planar planar member of the clamping device extends outwardly beyond a side edge of the bellows-like section. The fastening device may have a folded edge away from the bellows-like portion to provide a longitudinal edge bent downward. In this way, the bellows-type section, in particular the front face of said section, remains flexible, without having parts joined to it, other than the plane of the planar member of the fixing device. As a result, greater flexibility of the bellows type section is achieved, resulting in an improved seal between the refrigerator door and the cabinet. In an alternative embodiment, the fixation device has an arc shape by nature. Preferably, the bellows-type section comprises a sealing cushion. When the package is in its alternative position, the sealing pad comes into contact with the inner door part to provide a device to prevent the penetration of external air between the inner door part and the package. It is preferable that the cabinet of the home appliance includes a metal strip that can be an integral part of the home appliance or a separate part, around at least a portion of its edge. It is also preferable that the upper part of the bellows-type section comprises a magnetic insert chamber. A seal is generated by virtue of the magnetic pressure between the magnet and the magnetic strip of the cabinet, an attraction that also serves to keep the door in the closed position, and avoids the penetration of external air towards the internal part of the domestic appliance. The invention will now be described by way of example only with reference to the accompanying drawings in which the same reference numerals are used to identify similar components. Figure 1 is a diagram of a known packaging, in situ on the refrigerator door; Figure 2 is a diagram of a package according to the first embodiment of the present invention, in situ in a refrigerator door; and Figure 3 is a diagram of a package according to a second embodiment of the present invention, in situ in a refrigerator door. With reference to Figure 2, a package is illustrated through the reference number la. The door of the refrigerator 2 comprises an external door part 3 and an internal door part 4. The internal door part 4 has a slot 6 around its perimeter, where a part of the packing is located. The package comprises a flexible bellows-type section 8, and a fastener 10a. The bellows-type section 8 includes a base 9, a magnetic insert chamber 19 for a magnetic insert 20, and sealing pads 13a and 13b. The sealing pads 13a and 13b abut against the inner door portion 4 when the package is retained in the slot 6 (as illustrated) to thereby achieve a seal for the inner door part 4 and prevent penetration of the inner door portion 4. external air towards the internal part of the domestic appliance. The fastener 10a comprises a fastening device 21 in the form of a substantially planar member, which is fixed on the bellows-like section 8 and which has a longitudinal edge 22 that is blown downwards. In this way, the front wall 23 of the bellows-type section remains flexible, resulting in an improved seal between the refrigerator door and the cabinet. The fastener 10a also comprises a part of the fastener 24 which has a shape such that it can be releasably held in the groove 6 of the inner door part 4 in order to fix the gasket on the refrigerator door 2. The fastener part 24 is made of a rigid material and comprises two resiliently deformable legs 25 and 26, each having an upper end 25a and 26a, respectively and a bottom end 25b and 26b, respectively. The legs 25 and 26 are fixed on the fixing device 21 at their upper ends 25a and 26a. The legs 25 and 26 have hooks 27 and 28 bent upwards opposite each other, forming return legs respectively, which are at their bottom ends 25b and 26b, thus providing the profile of the upper part 24 with the approximate shape of the letter "W". " The legs 25 and 26 are such that, when the fixing device 10a is in its operative position, they push down to retain the gasket in place in the refrigerator door 2. The legs 25 and 26 engage opposite side walls of the refrigerator. the slot 6 to provide a gripping action as a result of equal and opposite forces between the respective legs and the opposite inner walls. The resiliently deformable legs 25 and 26 are positioned towards the end of the base 9 which is displaced horizontally from the magnetic insert chamber 19. The legs 25 and 26 can be pressed between them in order to effect the insertion of the fixing part. 22 in the groove 6. The legs 25 and 26 engage the groove 6 at an acute angle relative to the vertical and thus have a cam action against the groove 6, to retain the gasket in position in the door. The groove 6 has a shape such that it defines a narrow opening in its inlet 18, which facilitates the fastening of the package inside the groove 6 through the plates 25 and 26. With reference to Figure 3, a package is illustrated through reference number Ib. The refrigerator door 2b shown in this figure is identical to the door illustrated in figure 2. As in the case of the first embodiment, a part of the package Ib is located in the slot 6 around the perimeter of the inner door part 4 Although in the embodiments described above the slot 6 extends around the perimeter of the door and the profile of the packaging is continuous, it will be noted that the formation may take the form of numerous holes spaced around the perimeter of the door. On this last case, the packaging profile is discontinuous. The package Ib comprises a flexible bellows-like section 8b and a fastener 10b. The bellows-like section 8b has a base 9b and a profile defining a magnetic insert chamber 19b upon receipt of a magnetic insert 20b. The base 9b of the bellows-type section 8b further includes a profile 27 defining a hollow chamber. The profile 27 that acts as a "visual" stamp. The profile 27 rests against the outer door part 3 when the package Ib in the slot 6 to prevent the penetration of external air and moisture between the package Ib and the external door part 3. The bellows-type section 8b also includes a sealing pad 28 which bears against the inner door part 4, to provide a seal for the inner door part. The fastener 10b comprises a fastening device 21b and a fastener part 24b. The fastening device 21b is in the form of a tantially planar member which is fixed on the bellows-like portion 8b at base edges 29 and 30 of the bellows-like section 8b. The tantially planar member of the locking device 21b extends outwardly beyond a side edge 31 of the bellows-like section 8b to form a short platform. The fastener part 24b is identical to the part described in Figure 2 and, as in the case of the fastener part 24a, the fastener part 24b is displaced horizontally relative to the magnetic insert chamber 19b. The packaging of the present invention ensures that the holding force of the fixing device does not deteriorate over time which offers the advantage that the package does not undesirably slip out of the refrigerator door. The shape of the fixing part ensures that the height of the packing above the refrigerator door remains constant and therefore ensures that the fixing device does not slide into the slot. This results in fewer sealing problems, and less penetration of external air into the cabinet which mitigates unnecessarily high energy consumption. The effective length of the resiliently deformable leg of long thin wall rigid polymer consists of the sum of the legs 24, 25, 26 and 27. Such long / thin walled legs have a lower force by deflection gradient compared to short legs / thick wall (see, figure 1, 15 and 16). This means that for a given force a greater deflection is generated through the long / thin-walled legs, which allows the fastener part to be more easily inserted into the grooves that have a greater variation in width while offering high levels of retention. The force required to insert the fastener is further minimized by the low coefficient of friction of the rigid polymer legs compared to the packages having smooth polymer portions and the oblique curve shape of the other legs 27 and 28. In addition, having a fixing device of symmetrical shape, the fixing part is centered in the door slot.
