ABSTRACT:
FIELD OF THE INVENTION
This invention relates to individual packages for absorbent devices that are worn interlabially by female wearers for catamenial purposes, incontinence protection, or both. More particularly, the present invention relates to individual packages for interlabial devices that provide hygienic insertion of the interlabial device.
BACKGROUND OF THE INVENTION
All manner and variety of absorbent articles configured for the absorption of body fluids such as menses, urine and feces are, of course, well known. With respect to feminine protection devices, the art has offered two basic types; sanitary napkins have been developed for external wear about the pudendal region while tampons have been developed for internal wear within the vaginal cavity for interruption of menstrual flow therefrom. Such tampon devices are disclosed in U.S. Pat. No. 4,412,833, entitled “Tampon Applicator,” issued to Weigner, et al. on Nov. 1, 1983, and U.S. Pat. No. 4,413,986, entitled “Tampon Assembly With Means For Sterile Insertion”, issued to Jacobs on Nov. 8, 1983.
Hybrid devices that attempt to merge the structural features of the sanitary napkins and the tampons into a single device have also been proposed. Such hybrid devices are disclosed in U.S. Pat. No. 2,092,346, entitled “Catamenial Pad,” issued to Arone on Sep. 7, 1937, and U.S. Pat. No. 3,905,372, entitled “Feminine Hygiene Protective Shield,” issued to Denkinger on Sep. 16, 1975. Other less intrusive hybrid devices are known as labial or interlabial sanitary napkins and are characterized by having a portion which at least partially resides within the wearer's vestibule and a portion which at least partially resides external of the wearer's vestibule. Such devices are disclosed in U.S. Pat. No. 2,662,527, entitled “Sanitary Pad,” issued to Jacks on Dec. 15, 1953, and U.S. Pat. No. 4,631,062, entitled “Labial Sanitary Pad,” issued to Lassen, et al. on Dec. 23, 1986.
Interlabial pads have the potential to provide even greater freedom from inconvenience because of their small size and reduced risk of leakage. Numerous attempts have been made in the past to produce an interlabial pad which would combine the best features of tampons and sanitary napkins while avoiding at least some of the disadvantages associated with each of these types of devices. Examples of such devices are described in U.S. Pat. No. 2,917,049 issued to Delaney on Dec. 15, 1959, U.S. Pat. No. 3,420,235 issued to Harmon on Jan. 7, 1969, and U.S. Pat. No. 4,595,392 issued to Johnson, et al. on Jun. 17, 1986. A commercially available interlabial device is FRESH 'N FITS PADETTE interlabial product that is marketed by Athena Medical Corp. of Portland, Oreg. and described in U.S. Pat. Nos. 3,983,873 and 4,175,561 issued to Hirschman on Oct. 5, 1976 and Nov. 27, 1979, respectively.
If the consumer needs only one interlabial pad for later use, the consumer must take precautions to protect the interlabial pad from soiling or contamination from the time it is removed from the box or bag until the article is used. This is a particular concern with respect to maintaining a sanitary environment during insertion and removal. That is, a need exists to hygienically store an individual interlabial pad while being transported to prevent transferring unsanitary particles to the interlabial space.
The packaging for the commercially available FRESH 'N FIT® PADETTE® interlabial product is made from a coated paper sheet that is wrapped around the product and sealed on the transverse ends and along the longitudinal edges. The transverse ends and longitudinal edges of the product are sealed with an adhesive and are then crimped together. Another example of packaging for an interlabial pad is shown in U.S. Pat. No. 4,743,245 entitled “Labial Sanitary Pad” that issued to F. O. Lassen, et al. on May 10, 1988. However, there are drawbacks to these packages.
One important drawback is that these wrappers do not provide a means for users of interlabial products to preserve hygiene when inserting an interlabial device into the folds of the skin. The lack of hygiene in restrooms, the need to touch the doors of nonhygienic restrooms, and the necessity to touch themselves while inserting the device may result in the possibility of infection. In addition, when inserting the device during menstruation, it is desirable to keep the user's hands free from soiling. Therefore, the consumer needs an individual package that will protect the user's hand, fingers and the hygienic nature of the product.
Other packages for sanitary articles are described in U.S. Pat. No. 3,062,371 entitled “Internally Sterile Composite Package” that issued to D. Patience on Nov. 6, 1962 and U.S. Pat. No. 3,698,549 entitled “Package s for Small Articles” that issued to J. A. Glassman on Oct. 17, 1972. The Patience patent describes a package that is opened by folding back a panel from the package and removing its content by using sterile forceps. The Glassman patent describes a package that has internal pockets for holding flat articles such as gauze dressings or surgical sponges. The package is opened and exposes separate pockets for removal of individual articles.
Although the packages described in the Patience patent, the Glassman patent, the wrapper used with the PADETTE product, and the wrapper described in the Lassen patent protect the enclosed article, the package or wrapper does not aid in the hygienic insertion and placement of the product or provide a barrier to prevent the wearer's hand from touching the product or the wearer's body.
Packages for tampons are described in U.S. Pat. No. 3,135,262 entitled “Tampon” that, issued to W. Kobler, et al. on Jun. 2, 1964 and U.S. Pat. No. 5,180,059 en titled “Package of a Sanitary Tampon” that issued to S. Shimatani and K. Shimatani on Jan. 19, 1993. The Kobler patent describes a wrapper that when unwrapped, forms what Kobler describes as an umbrella to cover the user's hands. Because of the shape of the tampon (the height of the tampon is considerably greater than the tampon's longitudinal dimension), the wrapper must be considerably longer than the tampon to encircle the user's hand when opened. When the wrapper is opened, the material that forms the shield is large and would be an impediment to proper placement. Additionally, the wrapper in the Kobler patent does not completely seal all parts of the product inside the package creating the potential for contamination. Specifically, the tear cord used to break the band that holds the wrapper onto the tampon must be touched by the user. The same cord, when the tampon is in use, then resides in the vaginal region that is sensitive to contamination.
The Shimatani patent describes a package that comprises packing sheets superimposed on another to enclose the tampon to create a shield when inserting the tampon. This patent fails to provide a sterile environment because it, too, does not seal all parts of the product inside the package that should be protected from contamination or prevent the user from touching parts that should maintain sterility. Additionally, the stiffness of the Shimatani package would not provide the user comfort when inserting the article.
The packages for the Kobler and Shimatani patents are tall and circular in shape. The Kobler and Shimatani packages may be suitable in packaging articles that have a height greater than its longitudinal dimension, however, with smaller articles such as an interlabial product where its longitudinal dimension is greater than the article's height, such a wrapper would not be feasible. The package of the present invention is flat in comparison and uses side panels to provide the user hygienic, comfortable insertion and placement of the interlabial device. Also, the package of the present invention differs from the Kobler and Shimatani packages because they are not flushable or biodegradable.
Therefore, it is an object of the present invention to provide a hygienic individual package for an interlabial device.
