A container for a food product includes a wrapper which surrounds a frame. The container can be any polygonal shape which is defined by the shape of the frame. The wrapper forms a top of the container which has an access opening. A sealing cover is adhesively sealed to the top around the opening. The sealing cover is operable to expose the access opening and reclosable against the top to seal the access opening. The sealing cover, adhesive and top surface are optimized to provide sealing characteristics of sufficiently resealing frequency, relatively low noise level during unsealing and desirable peel forces to separate the seal between the sealing cover and the top.

An organic / inorganic composite separator includes (a) a polyolefin porous substrate having pores; and (b) a porous active layer containing a mixture of inorganic particles and a binder polymer, with which at least one surface of the polyolefin porous substrate is coated, wherein the porous active layer has a peeling force of 5 gf / cm or above, and a thermal shrinkage of the separator after being left alone at 15O DEG C for 1 hour is 50% or below in a machine direction (MD) or in a transverse direction (TD). This organic / inorganic composite separator solves the problem that inorganic particles in the porous active layer formed on the porous substrate are extracted during an assembly process of an electrochemical device, and also it may prevent an electric short circuit between cathode and anode even when the electrochemical device is overheated.

A nasal dilator comprises a laminate of vertical layers each consisting of one or more members or components. The laminated layers form a unitary, or single body, truss featuring horizontal regions adapted to engage outer wall tissues of first and second nasal passages and to traverse the bridge of a nose therebetween. When in use the dilator acts to stabilize and / or expand the nasal outer wall tissues and prevent said tissues from drawing inward during breathing. The dilator includes means to direct its resilient properties comprising one or more interior or exterior material separations, or discontinuity of shape of material, formed in at least one region of the truss and extending through at least one layer of the dilator. Said material separation or discontinuity of shape may comprise an opening, relief cut, slit or notch, and which may be configured to separate or vertically protrude, in part, from the truss when the dilator is in use on the nose of a wearer. Said separation or vertical protrusion changes the angle of focused delaminating spring biasing forces generated by the resilient layer, transforming said forces, at least in part, from primarily peel forces into primarily shear forces, and further redistributing or imparting said transformed forces to tissue engaging surface areas extending outward and beyond said material separation.

A flexible container with a wall structure comprised of multi-layer, flexible thin films, including a first film layer that is affixed to the wall structure by a releasable adherence and that incorporates a removable piece. The removable piece is incorporated into the first film layer such that, other than at least one continuous cut facilitating removal and any conspicuous printing on the removable portion, it is indistinguishable from the rest of the exterior of the package. The continuous cut allows for full or partial detachment of the removable portion from the first film layer so that only the releasable adherence prevents it from separating from the container. The removable piece is removed by peeling it away from the container, where the initiation of the peeling is facilitated by a smaller peel force adjacent the continuous cut. The removable piece may function as a promotional or collectible piece such as a gaming piece or redeemable coupon, or may be designed to retain a tacky surface and function as a sticker or as a piece of tape to close an opened bag. The removable piece can also expose a tacky surface on the container to permit closure of the opened bag.

An organic / inorganic composite separator includes (a) a polyolefin porous substrate having pores; and (b) a porous active layer containing a mixture of inorganic particles and a binder polymer, with which at least one surface of the polyolefin porous substrate is coated, wherein the porous active layer has a peeling force of 5 gf / cm or above, and a thermal shrinkage of the separator after being left alone at 150° C. for 1 hour is 50% or below in a machine direction (MD) or in a transverse direction (TD). This organic / inorganic composite separator solves the problem that inorganic particles in the porous active layer formed on the porous substrate are extracted during an assembly process of an electrochemical device, and also it may prevent an electric short circuit between cathode and anode even when the electrochemical device is overheated.

A pad for cleaning a hard target surface. The pad may be removably attached to a device for cleaning debris from a target surface. The pad has a predetermined 90 degree peel force to prevent undue removal force from the device and prevent the pad from coming loose during the cleaning task.

An ostomy appliance having a face plate assembly and inner and outer pouches joined thereto, has its outer pouch provided with one or more peripherally-extending sealing seams that allow the walls of the outer pouch to be separated by peeling forces applied in directions transverse to such seam or seams. In preferred embodiments, the sealing seam, also peelably join the peripheral edges of the outer pouch to those of the inner pouch. A method of disposing of the pouch assembly of such an ostomy appliance is also disclosed.

The invention provides an optical-use adhesive sheet excellent in adhesiveness under bending, twisting or distorting stress. The optical-use adhesive sheet has an adhesive layer having a storage elastic modulus at 80 DEG C of at least 2.0X10 4 Pa and a loss elastic modulus at 80 DEG C of at least 1.0X10 4 Pa, the optical-use adhesive sheet is characterized in that the adhesive sheet has a peel force, as measured in the L-shape peel test, of at least 0.16 MPa, and has a peel distance, as measured in the constant-load peel test, of at most 50 mm. In the L-shape peel test, an L-shaped stainless steel clamp is adhered with an acrylicresin plate through the adhesive sheet, the acrylicresin plate and the stainless steel clamp are processed for 15 minutes at 50 DEG C under 5 atm, and then, the stainless steel clamp is drawn along a direction vertical to a surface of the acrylicresin plate so as to test the peel force. In the constant-load peel test, a double-faced adhesive sheet is adhered on the acrylicresin plate, then, the acrylicresin plate and the double-faced adhesive sheet are processed for 10 minutes at 50 DEG C under 5 atm, and then, a load of 100gf is applied along the direction vertical to the surface of the acrylicresin plate on a tail end in a length direction of the adhesive sheet so as to test the peel distance of the adhesive sheet after 3 hours.

A process includes (i) the steps of adhering a pressure-sensitive adhesive layer supported on a base material to a release layer containing a mixture of a polyethylene and an ethylene / alpha-olefin copolymer and aging the resultant structure at 40 to 75° C. for 6 hours or more or (ii) the steps of adhering a pressure-sensitive adhesive layer supported on a base material to a release layer containing a linear ethylene-based resin in which the content of components eluted at 30° C. or lower measured by the temperature rising elution fractionation method is 3 to 30 wt % and aging the resultant structure at 55 to 75° C. for 6 hours or more, to thereby regulate the pressure-sensitive adhesive layer so as to have a peel force of 0.5 to 5 N / 50 mm when peeled from the release layer at an angle of 180° and a rate of 2 m / min together with the support base material.
