  • Publication number: 20220241449
    Abstract: Closure mechanisms for closing and sealing sterilization containers and indicators for indicating the seal integrity sterilization containers are provided. For example, a container closure mechanism may be configured to distribute a closure force along a gasket to seal a container lid to a container body. Further, a seal indicator may visibly indicate at the container exterior whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is a first state, and if the sterilization container is not sufficiently sealed, the seal indicator is in a second state. Thus, the seal indicator undergoes a state change when the sterilization container transitions from unsealed to sealed or from sealed to unsealed, such that a user can ascertain whether the container is properly sealed to maintain sterility or whether the seal and sterility of the container have been compromised.

  • Patent number: 10744739
    Abstract: A splash resistant multi-layered structure is provided. The structure includes a specific arrangement of layers of material and a plurality of three-dimensional spacers that helps prevent penetration through the structure by a fluid that contacts an outer surface of the structure due to a state of forced separation that exists between two adjacent layers of the structure due to the presence of the plurality of three-dimensional spacers positioned between the layers. The plurality of three-dimensional spacers can be positioned on one of the adjacent layers of the structure such that a distance at least as large as the maximum height of the plurality of three-dimensional spacers separates the two layers from each other and can be present on a layer of material in a continuous or discontinuous pattern or can be present on a layer of material in a random fashion.

  • Patent number: 8377027
    Abstract: Absorbent articles having form fitting properties are disclosed. In particular, the absorbent articles include at least one waist elastic member that extends a substantial distance in the longitudinal direction. The waist elastic member, for instance, may be positioned in a front region of the article, in a back region of the article or in both the front and back regions. The waist elastic member includes a breathable elastic film. In order for the film to be breathable, the film includes apertures. The apertures appear on the film according to a particular pattern and having a particular diameter so that the film retains desired stretch properties.

  • Patent number: 7517579
    Abstract: A bonded structure including one or more substrates bonded together with a tackified amorphous poly-alpha-olefin adhesive composition. One method of making such a bonded structure is carried out by applying a tackified amorphous poly-alpha-olefin adhesive composition to one or more substrates at a temperature of about 170 degrees Celsius or lower, and joining the substrates to themselves or to one another. The bonded structure has a dynamic peel strength between about 400 and about 1000 grams per 25 millimeters. The bonding efficiency of the bonded structure renders the bonded structure suitable for incorporation into a variety of articles, including personal care products, health/medical products, and household/industrial product, for example.

  • Patent number: 7329621
    Abstract: Stretchable film laminates including a layer of elastomeric openwork, such as a plurality of elastic strands or an elastomeric mesh structure. The stretchable film laminates may include a film layer bonded to the layer of elastomeric openwork, with the film layer having cross-directional stretch and the laminate having a multi-phase stretchability profile. The stretchable film laminates may be made by extruding a film from a die, stretching the film, forming and stretching a layer of elastomeric openwork, conveying the stretched elastomeric openwork onto the film while the film is stretched, and passing the film and the elastomeric openwork through a nip. The invention also includes a machine capable of producing machine-direction, cross-direction, and biaxial stretch materials. The machine includes at least one extruder, at least one filament die and at least one film die both attached to the extruder(s), and at least one nip downstream of the extruder(s).

  • Publication number: 20040102125
    Abstract: An extensible laminate includes a sheet of an extensible nonwoven material that has a fabric side and a film side, a sheet of an elastomeric film, and an adhesive. The adhesive is applied to at least a portion of the film side of the extensible nonwoven material. The extensible nonwoven material is selectively attached to the elastomeric film by a plurality of intermittent adhesive bonds. The extensible nonwoven material is further selectively attached to the clastomeric film by a plurality of thermal point bonds.
