Abstract
A method of individually packaging a single-use disposable diaper for use in intimate absorption of body fluid includes compressing a single-use disposable diaper for use in intimate absorption of body fluid from a first condition to a second, compressed condition, and retaining the single-use disposable diaper in the second, compressed condition with a pressure differential that acts upon a substantially flexible, substantially air impermeable material to maintain the single-use disposable diaper in the compressed condition. The pressure differential is created by locating the single-use disposable diaper in an interior space of a substantially air impermeable, substantially flexible material, creating a negative pressure within the interior space, and hermetically sealing the single-use disposable diaper at the negative pressure within the flexible material. The single-use disposable diaper is the only single-use disposable diaper contained within the hermetically sealed substantially air impermeable, substantially flexible material.

VI. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0041] As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (Ordinary Artisan) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being preferred is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
[0042] Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
[0043] Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
[0044] Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used hereinas understood by the Ordinary Artisan based on the contextual use of such termdiffers in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
[0045] Furthermore, it is important to note that, as used herein, a and an each generally denotes at least one, but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to a picnic basket having an apple describes a picnic basket having at least one apple as well as a picnic basket having apples. In contrast, reference to a picnic basket having a single apple describes a picnic basket having only one apple.
[0046] When used herein to join a list of items, or denotes at least one of the items, but does not exclude a plurality of items of the list. Thus, reference to a picnic basket having cheese or crackers describes a picnic basket having cheese without crackers, a picnic basket having crackers without cheese, and a picnic basket having both cheese and crackers. Finally, when used herein to join a list of items, and denotes all of the items of the list. Thus, reference to a picnic basket having cheese and crackers describes a picnic basket having cheese, wherein the picnic basket further has crackers, as well as describes a picnic basket having crackers, wherein the picnic basket further has cheese.
[0047] Referring now to the drawings, an absorbent article is shown in
[0048] For example, the absorbent article 10 is shown in
[0049] The absorbent article 10 is illustrated schematically in the drawings but may be configured as any type of absorbent article as known in the art, for example, a diaper, either infant or adult, a feminine sanitary napkin, and so on. The absorbent article 10 is made from resilient and compressible material that is able to retain fluid. Examples of diapers are disclosed in U.S. Statutory Invention Registration No. H1674 and U.S. Pat. Nos. 5,520,674; 5,522,810; 5,855,574; 5,876,393; and 5,980,500. Examples of feminine sanitary napkins are disclosed in U.S. Pat. Nos. 5,490,847; 5,653,702; 5,792,131; 5,797,894; and 6,015,934. The disclosure of each of these patents is incorporated herein by reference.
[0050] Being made from resilient absorptive material, exemplary article 10 is compressible in at least one dimension. However, to minimize the amount of compressed volume V.sub.c, it is preferable for the absorbent article 10 to be compressible in three dimensions, as mentioned above. More specifically, as shown in
[0051] To compress, the absorbent article 10 may be subject to compressive force, thereby forcing air out of the inter-fiber spaces 14 and compressing the absorptive material 12. Alternatively, the absorbent article 10 may be subject to vacuum, thereby drawing air out of the inter-fiber spaces 14 and compressing the absorptive material 12. Once compressed, the absorbent article 10 is retained to maintain the compact and highly portable configuration, for example, by shrink-wrap thermoplastic packaging at a vacuum or negative pressure, which will be discussed in more detail below. To use, the retaining packaging is disengaged or opened, allowing the absorbent article 10 to return to expand under the resiliency and elasticity of the absorptive material 12, which is also discussed in more detail below.
[0052] As mentioned above, the absorbent article 10 is shown in a normal condition in
[0053] After being placed in a reconfigured condition, the absorbent article 10 may then be compressed as discussed above, thereby placing the article in a compressed condition. If reconfigured by rolling as shown in
[0054] After being compressed, the absorbent article 10 may then be retained to maintain the compressed condition, for example, with packaging 16 as shown in
[0055] Other examples of how an absorbent article may be reconfigured are illustrated by
[0056] After the diaper 82 is reconfigured, it may be compressed and maintained in the compressed configuration by vacuum-packaging. For example,
[0057] Another example of a diaper 82 that has been reconfigured and then vacuum-packaged within an encasement 84 is shown in
[0058] Yet another example of reconfiguring a diaper and then packaging the diaper is illustrated by
[0059]
[0060] From the rectangular configuration of the diaper 20 shown in
[0061] The diaper 20 may then be vacuum-packaged within an air and moisture impermeable encasement 32. The resulting vacuum-packaged diaper is illustrated in
[0062] As shown in
[0063] In addition to individually compressed and packaged absorbent articles such as articles 18,80,118, a plurality of compressed absorbent articles may be packaged together in various multipack arrangements. One multipack of individually compressed and packaged absorbent articles 110 is shown in
[0064] Another example of a multipack of individually compressed and packaged absorbent articles is shown in
[0065] Another example of a multipack 150 of individually compressed and packaged absorbent articles is shown in
