摘要:
A flexible bag comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an interior surface, an exterior surface, an opening having a peripheral edge, and a support-engagement feature located on the exterior surface at least partially surrounding the peripheral edge. The support-engagement feature comprises a strip of material having a first side facing outwardly from the exterior surface and a second side facing inwardly toward the interior surface. The first side exhibits an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user. The support-engagement feature preferably at least partially, and more preferably fully, circumferentially surrounds the peripheral edge. The selectively-activatible support-engagement feature also preferably functions as a closure means to secure the opening of the flexible bag in a substantially closed condition when the bag material is gathered about the opening, thus providing for ease of sealability without the need for additional closure features or separate elements. Additional closure means may be provided utilizing the selectively-activatible materials suitable for use as a support-engagement feature located on the inner surface of the peripheral edge of the bag. The support-engagement features of the present invention provide a flexible bag which is capable of reliably engaging a supporting device so it may be supported in an open condition for filling purposes. Such a feature also reduces the likelihood of trapped air and/or free space occurring when the bag is utilized with a rigid or semi-rigid durable container.

The present invention relates to a tampon applicator arrangement, having tampon, applicator unit and a film cap, attached thereto, which is at least partially uniformly shaped, typically being conforming to part or all of the tampon or applicator unit, or such that the film cap has the lowest possible surface area. The film cap is so shaped and/or generally under tension and has no rugosites, folds or even wrinkles, other than optionally tension wrinkles, and preferably also no seams or welds. The invention also relates to specific moulding processes for making the film cap and the arrangement of the invention. The arrangements of the invention provide a smoother, easier and safer insertion of a tampon in the body.
摘要:
The present invention relates an arrangement and a process for making the arrangement that comprises a tampon, an applicator unit, and a uniformly shaped film cap. The tampon has a withdrawal end opposed to an insertion end, the insertion end having a top portion. The applicator unit contains at least a portion of a tampon and has a bottom side opposed to a topside. The film cap is uniformly shaped and covers at least a portion of the top portion of the tampon and attaches to at least a portion of the applicator unit. The arrangement is obtainable by a process comprising the steps of attaching the planar film to the applicator and shaping and or stretching the planar film to create a film cap.

An embossing and adhesive application process including the steps of: applying an adhesive to a first patterned embossing roll which is engaged with a second patterned embossing roll having a complementary pattern to the first embossing roll; passing a web of sheet material between the first and second embossing rolls at a tangential line speed to simultaneously emboss the web and direct the adhesive against the web; and splitting the adhesive such that at least some of the adhesive remains on the first embossing roll and some of the adhesive remains on the web to form an adhesive pattern between embossments on the web.

The present invention relates to an improved storage wrap material comprising a sheet of material comprising one or more layers, and having a first, active side and a second side, said sheet comprising a plurality of standoffs at a density of greater than about 200 standoffs per square inch; and an adhesive; wherein the standoffs are selected from the group consisting of deformable standoffs, removable standoffs, repositionable standoffs, frangible standoffs, or mixtures thereof; and wherein the storage wrap material is linerless and consists of no reinforcing or supporting elements.
摘要:
The present invention relates to sheet-like materials suitable for use in the containment and protection of various items, as well as the preservation of perishable materials such as food items. More particularly, the present invention provides an improved storage wrap material comprising a sheet of material having a first side and a second side. The first side comprises an active side exhibiting an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user. The storage wrap material may be activated by different approaches, but in a preferred embodiment the active side is activatible by an externally applied force exerted upon the sheet of material. The force may be an externally applied compressive force exerted in a direction substantially normal to the sheet of material. In accordance with the present invention, the storage wrap material is selectively activatible by a user in discrete regions to provide adhesive properties where and when desired. The use of an adhesive or adhesive-like substance on the surface of the material provides an adhesion peel force after activation which is sufficient to form a barrier seal against a target surface at least as great as those of the material and the target surface such that perishable items, such as food items, may be effectively preserved. The storage wrap materials of the present invention may be utilized to enclose and protect a wide variety of items by various methods of application, including direct application to the desired item, enclosure of the desired item and securement to itself, and/or in combination with a semi-enclosed container.

摘要:
The present invention provides a selectively-activatible sheet material for delivering a substance to a target surface. The sheet material comprises a three-dimensional sheet of material having a first side and a second side. The first side has a plurality of hollow protrusions extending outwardly therefrom and separated from one another by valleys, while the second side has a plurality of depressions corresponding with the hollow protrusions. A substance adheres to and partially fills a location protected from external contact comprising the valleys and/or depressions. The sheet material may be selectively activated by deforming the hollow protrusions to deliver the substance to a target surface. The three-dimensional structure includes hollow protrusions which are adapted to progressively activate in multiple discrete stages to effect multistage progressive delivery of the substance to the target surface. The present invention also provides selectively-activatible sheet materials which incorporate a three-dimensional structure adapted to progressively activate in response to increasing compressive force levels via tailoring of the geometrical shapes of respective hollow protrusions. The present invention also provides selectively-activatible sheet materials which incorporate a three-dimensional structure adapted to progressively activate in response to increasing levels of deformation via tailoring of the geometrical shapes of respective hollow protrusions.
