A pet toy includes a core body and a coating layer. The core body is made of a first material. The core body includes a first core body member and a second core body member that are mated together to have a space therebetween. The coating layer covers the core body. The coating layer is made of a second material that is different from the first material.

A manufacturing method of a seating device includes manufacturing an outer skin; manufacturing a core member via a foaming process; wrapping the core member in the outer skin, coupling a mounting plate at a bottom surface of the core member; and selectively coupling a mounting structure to the mounting plate to form the seating device. The outer skin is constructed to have a top skin layer adhered on a top surface of the core member, a side skin layer adhered on a side surface of the core member, and a bottom skin layer adhered on a bottom surface of the core member. Particularly, the top skin layer of the outer skin is adhered on the top surface of the core member edge-to-edge to initially align and retain the outer skin on the core member.

A helmet and method for forming a helmet having a multi-density impact liner may include forming a puck comprising an interface surface and at least one side is formed. The interface surface of the puck is placed in direct contact with a receiving surface of a cap located in an impact liner mold. Next, the interface surface of the puck is thermally fused directly to the receiving surface of the cap while contemporaneously an impact liner body is formed inside the mold. The impact liner body is fused to the at least one side of the puck, and to a majority of the receiving surface of the cap. The density of the puck may be greater than the density of the impact liner body. The puck and the impact liner body may be expanded polystyrene (EPS), and the cap may be polycarbonate (PC).

In a pallet manufacturing method, variations of pallets, having different thicknesses of pallet bodies, heights of legs, or foaming ratios thereof, are manufactured at low cost and with high quality. The method includes a pallet body molding step for molding a plurality of the pallet bodies of a plurality of types having different thicknesses or expansion ratios of foaming; a leg molding step for molding, separately from the pallet body, a plurality of legs of a plurality of types having different heights or expansion ratios of foaming; and a vacuum forming step for forming a resin sheet for covering and integrating the pallet body and the legs from a bottom surface side of the pallet by vacuum integral forming after the pallet body and the legs are selected, respectively, from the plurality of types and assembled in a state that the legs are mounted on the pallet body.

A thermoset foam comprises from 0.2 to 4.0 wt. % of at least one aliphatic brominated polyether polyol, from 2.0 to 7.0 wt. % of at least one aromatic brominated polyester polyol, and from 2.0 to 7.5 wt. % of at least one flame retardant comprising organo-phosphate, organo-phosphonate, or organo-phosphite, wherein the ratio of the amount of aliphatic bromine expressed as a percentage of total bromine to the amount of aromatic bromine expressed as a percentage of total bromine is from 10:90 to 50:50.

A package delivery apparatus uses an unmanned aerial vehicle (UAV) to deliver a package containing a product to a delivery destination area. The UAV uses GPS signals to guide it to the delivery destination area and an altimeter to determine its height above the delivery destination area. The UAV then adjusts its height to a preferred drop or release height for that package and product and releases the package. An optional camera allows a human operator to view the delivery destination area. An expandable foam package surrounds the product to protect the product from impact and moisture. The package may be streamlined to reduce air resistance and increase the range of the UAV. The package characteristics, such as its thickness, are determined based one or more of the weight and fragile nature of the product, and the drop height.

A makeup blending sponge. The sponge comprises a foam core and a layer of coating. The layer of coating covers a portion of an outer surface of the foam core. The portion may be about 70% to about 90% of the total surface area of the outer surface of the foam core. The foam core may be polyurethane. The layer of coating is an elastomer, and may be a mixture of an elastomer and a thinning agent. The elastomer may be silicone. A method of manufacturing the makeup blending sponge and the use thereof are also disclosed.

A thermoset foam comprises from 0.2 to 4.0 wt. % of at least one aliphatic brominated polyether polyol, from 2.0 to 7.0 wt. % of at least one aromatic brominated polyester polyol, and from 2.0 to 7.5 wt. % of at least one flame retardant comprising organo-phosphate, organo-phosphonate, or organo-phosphite, wherein the ratio of the amount of aliphatic bromine expressed as a percentage of total bromine to the amount of aromatic bromine expressed as a percentage of total bromine is from 10:90 to 50:50.

There is provided a polyolefin resin foam sheet formed by foaming a polyolefin resin, wherein the expansion ratio of the foam sheet is 1.5 to 20 cm.sup.3/g, the average cell sizes in the MD direction and the TD direction of the foam sheet are 130 μm or less, and the following formulas (1) and (2) are satisfied:
T.sub.M/D≥6  (1); and
T.sub.T/D≥5  (2), where T.sub.M denotes the tensile strength at 90° C. in the MD direction, T.sub.T denotes the tensile strength at 90° C. in the TD direction, and D denotes the density (g/cm.sup.3) of the foam sheet.

A head-mounted display may include a frame for supporting an electronic display for viewing by an intended user donning the head-mounted display. The frame may include a flange disposed on a perimeter area of the frame and a facial interface configured to abut against an intended user's face wherein the facial interface comprises a foam body and an undercut region in the foam body that is sized and shaped for detachably engaging with the flange of the frame. Various other apparatuses, systems, and methods are also disclosed.
