Description

Description: TECHNICAL FIELD The present invention relates to an absorber individually packaged by a wrapper having a main wrapper sheet for the absorber and a flap fastener cover for the flap fastener of the flap.

BACKGROUND Absorbers such as sanitary napkins with a pair of flaps extending laterally outward from the absorbing means are known. One such absorber includes a pair of flaps extending laterally outward from the center of both longitudinal edges of the absorber. The flap is for folding around the edge of the wearer's underwear at the crotch. Thus, during use, the flap is placed between the edge of the wearer's underwear at the crotch and the wearer's thigh. Generally, the flap is provided with a flap fastener such as an adhesive for attaching the flap to the underside of the wearer's underwear. First, the flaps prevent exudates that would otherwise stain the underwear edge of the wearer from staining the underwear edge. Second, the flaps help stabilize the napkin from moving from the position chosen by the wearer. This is especially true when the flap is applied to the underside of the underwear.

Such a sanitary napkin flap can be folded to the topsheet side or the backsheet side, saving space during packaging, i.e., from the manufacture of the sanitary napkin to its first use by the wearer. When first used by the wearer, the flap is usually spread out to facilitate placing the sanitary napkin on the wearer's underwear. Before using the sanitary napkin, the flap fasteners of the folded flaps are usually covered with a flap fastener cover so that they do not accidentally stick to each other or other parts of the product. When the flaps are folded toward the topsheet, the flap fasteners of the flaps are facing outward and are covered by a flap fastener cover, thereby bridging the flaps over the topsheet. JP-A-5-293139 published on November 9, 1993, JP-A-6-78953 published on March 22, 1994, and Japanese Utility Model Publication No. No. 6,268,635 discloses a sanitary napkin having a flap folded over a topsheet and a flap fastener covered by a flap fastener cover. The sanitary napkin disclosed above further includes a main fastener for securing the sanitary napkin to the underwear of the wearer. Further, the main fastener is covered with a main fastener cover. Therefore, when using a sanitary napkin, the wearer must remove the flap fastener cover and the main fastener cover. The wearer must then properly dispose of the various fastener covers to prevent the fastener covers from becoming littered.

Attempts have been made to facilitate removal of the flap fastener cover and the main fastener cover from the sanitary napkin. Kaikaihei No. 5 released on February 9, 1993
No. 9526 and Japanese Utility Model No. 5-published on February 9, 1993
No. 9529 discloses a sanitary napkin with a body fastener, a flap with a flap fastener, and a sanitary napkin with a fastener cover for covering the flap fastener and the main fastener. The fastener cover includes a flap fastener cover portion and a main fastener cover portion that are connected to each other. Therefore, when the main fastener cover part is removed from the sanitary napkin body, the flap fastener cover part is also removed from the flap.

Other attempts to facilitate removal of the flap fastener cover and / or the main fastener cover from the sanitary napkin body have been made in connection with removing a wrapper for individually wrapping the sanitary napkin.
Japanese Utility Model Publication No. 6-26833 published on April 12, 1994 is a sanitary napkin body with a main zipper, a flap with a flap fastener, a wrapper for wrapping the sanitary napkin body, and a flap fastener cover. And a main zipper cover. Since the main zipper cover is connected to a part of the wrapper, when the sanitary napkin main body is removed from the wrapper, the main zipper cover is removed from the main body. However, the flap fastener cover must also be removed from the flap.

Japanese Utility Model Application Laid-Open No. 7-39820, published July 18, 1995, discloses a sanitary napkin having a sanitary napkin body having a topsheet, a backsheet and an absorbent core. Further, the sanitary napkin is provided with a pair of flaps which are folded around the underwear edge of the crotch wearer when using the sanitary napkin. The body is provided with an adhesive layer, and the flap is covered with an adhesive layer cover, which may individually include a wrapper for wrapping the sanitary napkin. The flap is folded inside the body. An adhesive cover that covers the adhesive layer of the body extends beyond the longitudinal sides and lateral edges of the body. The adhesive layer cover extends beyond one lateral edge, and the extended portion of the adhesive layer cover is folded inward to cover the adhesive layer of the flap. July 18, 1995
Japanese Utility Model Application Laid-Open No. 6-75446 discloses a sanitary napkin including a sanitary napkin main body and a pair of flaps extending horizontally outward from both sides in the longitudinal direction of the sanitary napkin. Before using the sanitary napkin, the flaps were folded on the body-facing side of the sanitary napkin,
When using a sanitary napkin, it is folded around the edge of the wearer's underwear at the crotch. The garment-facing side of the sanitary napkin provided with the adhesive layer is wrapped by a removably processed wrapper. The wrapped sanitary napkin is folded around the fold line with the wrapper. The publication further discloses a packaging structure for a sanitary napkin, wherein a portion of the wrapper covers the adhesive layer of the flap. That is, the lateral edge of the wrapper extends beyond the edge of the sanitary napkin and folds back against the adhesive layer of the flap that is folded over the topsheet. EP 0 750 896 A2 published on January 2, 1997 discloses a sanitary napkin comprising a napkin body and a pair of flaps extending from laterally opposite sides of the side edge of the napkin body. ing. The napkin body is folded vertically with the three layers overlapping, and the flap is also folded on the top surface of the napkin body. The release sheet is removably adhered to an adhesive area provided on the back surface and the flap of the napkin body. The wrapping sheet is also folded together with the napkin body so as to wrap the napkin body together with the flap, and each release sheet is firmly adhered to the inner surface of the wrapping sheet. It can be peeled off in the form of an integrated string-like sheet.

Another type of absorber comprises a pair of flaps extending laterally outward from behind the longitudinal sides of the absorbing means. A second type of flap of the absorber is one that extends to the inner rear of the wearer's underwear. In use, the flap is placed between the buttocks of the wearer and the underwear of the wearer. The second type of flap of the absorber also prevents exudate which would otherwise smear the back of the wearer's underwear. The flap is provided with a flap fastener such as an adhesive for attaching the flap to the inside of the wearer's underwear, and stabilizes the napkin from moving behind the wearer's underwear. The flap fasteners can be covered with a flap fastener cover prior to use of the sanitary napkin so that they do not accidentally stick together or with another part of the product.
JP-A-8-224269, published September 3, 1996, discloses individually packaged sanitary napkins. The sanitary napkin includes a topsheet, a backsheet, an absorbent core, a pair of flap portions having an adhesive layer on both longitudinally rear sides of the sanitary napkin, and a main adhesive layer covered with a main release paper. The back flap portion is folded to the top sheet side, the adhesive layer of the back flap portion faces upward, and flap release paper is attached to the adhesive layer. The wrapper is bonded to the non-openable surface of the main release paper using a first adhesive. The sanitary napkin is folded in three parts with the wrapper so that the flap release paper faces the backsheet side at the front of the sanitary napkin. A wrapper covering the front of the sanitary napkin is bonded to the non-openable surface of the flap release paper using a second adhesive.
