    Description


    [0001] The present invention relates to a package of grouped containers for products, especially for diapers or similar.

    Background of the Invention



    [0002] Currently, known baby diaper containers consist of a more or less compact container or plastic bag containing a predetermined number of diapers inside. The size of the container, in addition to the number of diapers it contains varies depending on the absorption range of the diaper itself, with the absorption level and volume of the diaper being larger, the larger the weight of the baby for which it is designed.

    [0003] Some known diaper containers present a higher capacity in terms of the number of units included, which provides a financial saving for the buyer. However, these higher-capacity containers have the drawback of presenting a larger weight and volume, said container occasionally being inconvenient to carry or store, particularly if having to take the container outside of the home.

    [0004] Therefore, modular package systems have been developed (WO 2005/110873 A1), whereby a dual container package in accordance with the preamble of claim 1 is disclosed by US 5 201 413 A.

    Description of the invention



    [0005] The object of the package of grouped containers for products, especially diapers or similar of the present invention is to resolve the drawbacks presented by the diaper containers known in the state of the art, by providing a package that is capable of being separated into at least two containers in a practical and simple way for the buyer and without affecting the process of reading the product codes on the part of the employee at the cash register of the commercial establishment, whether the buyer purchases a single container or the complete package.

    [0006] The package of grouped containers for products, especially for diapers or similar, object of the present invention, is of the type that comprises a set of preferably two individual containers, wherein the total sum of the products distributed in the containers within the package matches the number of products of a conventional container of equal capacity and similar size as the package, and is characterised in that said package comprises at least one joining label for two contiguous containers, provided with a perforated tear line located in the space between the two containers, capable of being torn to separate said containers, and an identification code of the package arranged on said tear line, capable of becoming illegible in the event of said label being torn, and in that the package is configured in such a way that it is capable of simultaneously hiding an identification code for each individual container, in such a way that according to a first option the package can be purchased whole by a user with the joining label intact, leaving only the package identification code visible, and according to a second option the package can be separated by a user in order to purchase an individual container, after tearing the joining label of the two containers and consequently breaking the package identification code, leaving only the respective code of the extracted container legible.

    [0007] In this way, a more versatile package is obtained since it can be purchased whole or separated into at least two individual containers in a simple manner on the part of the buyer. At the same time, any error on the part of the employee at the cash register of the commercial establishment is avoided, since only one identification code can be read.

    [0008] According to the invention, the package is configured in such a way that it also includes a holding strip joined to both containers in a removable manner, capable of simultaneously hiding the identification code of each individual container when the containers remain joined by means of the joining label.

    [0009] Therefore, if the buyer wishes to purchase the whole package, the holding strip will be hiding the codes of the individual containers leaving only the package identification code visible, and alternatively in the event of purchasing an individual container, it will only be possible to read the container code upon removing the holding strip, since the package code will have been broken by having previously torn the joining label of both containers along the perforated line.

    [0010] The holding strip comprises on its internal face two lateral zones provided with a removable adhesive, and a central zone not provided with adhesive intended to partially embrace both containers.

    [0011] According to an embodiment of the invention, the package is configured in such a way that the identification code of each individual container is arranged on the rear face of the container itself, the contiguous containers being assembled with their respective rear faces facing each other, capable of simultaneously hiding both identification codes of the containers when the package is formed and the containers remain joined by means of the joining label.

    [0012] Therefore, if the buyer wishes to purchase the whole package, the containers themselves in facing each other by their rear faces will be hiding the codes of said individual containers leaving only the package identification code visible, and alternatively in the event of purchasing an individual container, it will only be possible to read the container code when the rear face of the container is uncovered, because the package code will have been broken after previously tearing the joining label of the two containers along the perforated line.

    [0013] In this way, the fact that the two containers are facing each other by their rear faces, hiding respective identification codes of the individual containers, makes it possible to obtain a structurally simpler package since the holding strip is dispensed with.

    [0014] According to one variant, the package comprises two joining labels situated respectively on each side of both containers, and arranged in parallel at the same height.

    [0015] According to another variant, the package comprises two joining labels situated respectively on each side of both containers, and arranged in a crossed manner at a different height in order to improve the strength of the package.

    [0016] Advantageously, only one of the two joining labels includes the package identification code, irrespective of the side or height where said joining label is located.

    [0017] Preferably, the joining label comprises on its outer face an opaque central zone provided for printing said package identification code, and also, optionally, other additional information.

    [0018] Advantageously, the joining label comprises on its internal face two lateral zones provided with glue for adhesion to respective contiguous containers, and a central zone not provided with glue where the perforated tear line is located.

    [0019] Optionally, the joining label comprises a notch in at least one end of the perforated line designed to facilitate tearing.

    [0020] Preferably, the package identification code and the code of the corresponding individual containers are barcodes, capable of being read respectively by means of an optical reader belonging to the cash register of a commercial establishment.

    [0021] Preferably, the products contained in the package are distributed equally in each container.

    Description of preferred embodiments



    [0023] As can be appreciated from figures 1 and 2, the package 1 comprises a set of two individual containers 2 that contain baby diapers, in such a way that the sum total of the diapers distributed in the containers 2 within the package 1 matches the number of diapers in a conventional container of equal capacity and similar dimensions as the package 1.

    [0024] Said package 1 comprises a joining label 3 of both contiguous containers 2, provided with a perforated tear line 4 located in the space between both containers 2, capable of being torn to separate said containers 2, and an identification code 5 of the package 1 disposed on said perforated line 4, capable of becoming illegible in the event of said label 3 being torn.

    [0025] According to a first embodiment of the invention shown in figures 1 and 2, the package 1 also comprises a holding strip 6 joined to both containers 2 in a removable manner, capable of simultaneously hiding an identification code 7 of each individual container 2.

    [0026] In this way, according to a first option shown in figure 1, the package 1 can be purchased whole by a buyer with the joining label 3 and holding strip 6 intact, leaving only the identification code 5 of the package 1 visible, and according to a second option shown in figure 2, the package 1 can be separated by a buyer to purchase one individual container 2, after tearing the joining label 3 of both containers 2 and consequently breaking the identification code 5 of the package 1 and after removing said holding strip 6, leaving only the respective code 7 of the extracted container 2 legible.

    [0027] A more versatile package 1 is obtained since it can be purchased whole or separated into two individual containers 2 in a simple manner on the part of the buyer. At the same time, any error on the part of the employee at the cash register of the commercial establishment is avoided, since thanks to the joining label 3 and the holding strip 6 only one identification code 5 or 7 can be read.

    [0028] Therefore, if the buyer purchases the whole package 1, the holding strip 6 will be hiding the codes 7 of the individual containers 2 leaving only the identification code 5 of package 1 visible (see figure 1), and alternatively in the event of purchasing an individual container 2, it will only be possible to read code 7 of the container 2 upon removing the holding strip 6, since code 5 of package 1 will have been broken after previously tearing the joining label 3 of both containers 2 along the perforated line 4 (see figure 2).

    [0029] In reference to figure 3, the label 3 comprises on its outer face an opaque central zone 8 provided for the printing of said identification code 5 of the package 1, and also optionally other additional information, and a transparent perimeter zone 9.

    [0030] As can be appreciated from figure 4, the label 3 comprises on its internal face two lateral zones 10 provided with glue for adhesion to respective contiguous containers 2, and a central zone 11 not provided with glue where the perforated tear line 4 is located. It should be noted that said central zone 11 also would be provided with glue. In any case, the label 3 can be adhered to the containers 2 in a removable or permanent manner.

    [0031] Also, the label 3 comprises a notch 12 at both ends of the perforated line 4 intended to facilitate tearing, although it also would be produced without said notch.

    [0032] As can be observed in figure 5, the holding strip 6 comprises on its internal face two lateral zones 13 provided with a removable adhesive, although it also would be a permanent adhesive, and a central zone 14 not provided with adhesive intended to partially embrace both containers 2.

    [0033] Preferably, the identification code 5 of the package 1 and the code 7 of the corresponding individual containers 2 are barcodes, capable of being read respectively by means of an optical reader belonging to the cash register of a commercial establishment.

    [0034] In this case, the products contained in the package 1 are distributed equally in each container 2. In the illustrated example, the complete package 1 comprises double the products of each separate container 2. Thanks to the fact that the identification code 5 of the package 1 is different to the code 7 of each individual container 2, it is possible to associate different prices to the package 1 and to the container 2, which allows the complete package 1 to be offered at a cheaper price, with a lower cost per container unit, than if the two containers 2 are purchased separately.

    [0035] A second embodiment of the invention is shown in figures 6 to 11, wherein a package 1',1" is shown, which comprises the same elements as described with numerical references 2 to 12, excluding the holding strip 6.

    [0036] In this second embodiment, the package 1' is configured in such a way that the identification code 7 of each individual container 2 is disposed on the rear face 2a of the container itself 2, the contiguous containers 2 being assembled with their respective rear faces 2a facing each other, capable of simultaneously hiding both identification codes 7 of the containers 2 when the package 1' is formed.

    [0037] In this way, according to a first option shown in figures 6 and 7, the package 1' can be purchased whole by a user with the joining label 3 intact, leaving only the identification code 5 of the package 1' visible, and according to a second option shown in figure 8, the package 1' can be separated by a user to purchase one individual container 2, after tearing the joining label 3 of both containers 2 and consequently breaking the identification code 5 of the package 1', leaving only the respective identification code 7 of the extracted container 2 legible.

    [0038] Consequently, if the buyer purchases the whole package 1', the containers 2 themselves, in facing each other by their rear faces 2a will be hiding the codes 7 of said individual containers 2 leaving only the identification code 5 of the package 1' visible, and alternatively in the event of purchasing an individual container 2, it will only be possible to read the code 7 of the container 2 as the rear face 2a of the container 2 is left uncovered, since code 5 of the package 1' will have been broken by previously tearing the joining label 3 of both containers 2 along the perforated line 4.

    [0039] In this way, the fact that the containers 2 are facing each other by their rear faces 2a hiding the respective identification codes 7 of the individual containers 2, allows a structurally simpler package 1' to be obtained since the holding strip 6 is dispensed with.

    [0040] According to one variant, as can be appreciated from figures 6 to 8, the package 1' comprises two joining labels 3 situated respectively on each side of both containers 2, and arranged in parallel at the same height.

    [0041] According to another variant, as can be appreciated from figures 9 to 11, the package 1" comprises two joining labels 3 situated respectively on each side of both containers 2, and arranged in a crossed manner at a different height to improve the strength of the package 1".

    [0042] It is important to note that only one of the two joining labels 3 includes the identification code 5 of the package 1',1", irrespective of the side or height where said joining label 3 is located.

    [0043] Despite the fact that reference has been made to specific embodiments of the invention, it is obvious to a person skilled in the art that the package of grouped containers described is capable of numerous variations and modifications, and that all mentioned details can be replaced by other technical equivalents, without abandoning the scope of protection defined by the attached claims.
