Definitions

• US 2005/0077500 discloses a package with an enclosed compartment for storing an array of compressible articles.
• the package includes an expansion mechanism for allowing the enclosed compartment to be enlarged.
• EP 0 520 885 Al describes a dispensing device comprising two pieces of cardboard which are pre-tensioned with regard to each other in order to force tissue paper towards a dispensing opening in one of the cardboard pieces of the dispenser.
• One objective of the present invention is to provide a package for distributing and storing a plurality of compressible sanitary products which substantially maintains the absorption properties of the sanitary products inside the package, in particular the wicking properties.
• the resilient member is dimensioned such that it exerts a compression on the sanitary products from a full package down to a package filled to one third.
• the compression exerted on the sanitary products is substantially constant from a full package down to a . package filled to one third. This allows the maintenance of the wicking properties from the full package down to a package that is filled to at least one third.
• the resilient member to compress the sanitary products it is preferred to dimension the resilient member to compress the sanitary products to have a total bulk of 3-6 cm 3 /g. This compression ensures that the wicking properties and thus the absorption properties of the sanitary product are maintained.
• the values given are equally valid for absorbent products comprising superabsorbent polymers (SAP) and for products without superabsorbent polymers that only contain cores made from fibers .
• the resilient member is made from a natural elastic polymer and/or a synthetic elastic polymer exhibiting a high elongation.
• a resilient member that exhibits an elongation of at least 100%, preferably of at least 200%, more preferred of at least 300%, most preferred of more than 400%, in particular at least 500%.
• Such a resilient member has the advantage of maintaining the compression force over a wide range of quantities of sanitary products in the package.
• a resilient member of these material properties it is possible to maintain the compression in a package from a state in which it is fully filled with sanitary products down to a state in which only a few sanitary products remain. Most preferred, the compression is maintained until the last sanitary product in the package.
• the wrapper of the package can be inextensible, in particular an inextensible film. This has the advantage that the forces that are exerted by the resilient member can be transferred via the wrapper directly on the sanitary products. It is particularly preferred that the at least one resilient member interacts with the wrapper to compress the sanitary products contained within the wrapper.
• the package can comprise disposable diapers/napkins, in particular disposable baby diapers or disposable incontinence diapers, or sanitary napkins.
• disposable diapers/napkins in particular disposable baby diapers or disposable incontinence diapers, or sanitary napkins.
• sanitary napkins for these products, it is particularly advantageous that a constant pressure is exerted on each and every product before it is used in order to maintain the bulk and thus the wicking properties.
• Figure 1 is a schematic perspective view of a package in a first embodiment
• Figure 6 is a schematic view of the package of Figures 4 and 5 in an even more emptied state of the package;
• Figure 7 is a schematic view of a package of a fourth embodiment ;
• Figure 8 is a schematic perspective drawing of a package of a fifth embodiment;
• Figure 9 is a schematic diagram showing the wicking properties of absorption cores having different core bulks.
• Absorbent cores are formed by a mat formation process. This process includes shredding of pulp sheets into fibres and then depositing said fibres onto an air permeable carrier sheet. Below the carrier sheet one or more suction portions are placed to aid in depositing the fibres onto the carrier sheet. This formation results in absorbent cores which have a bulk value which is above 10 cm 3 /g. Due to this manufacturing method, the core has a fluffy structure and acts like a sponge material, i.e. if the core is compressed and then the compression force- is released, the core will tend to expand and, thereby, the bulk value will increase.
