Systems and methods are disclosed that include an operation chamber, a plasma generator having at least one plasma head disposed within the operation chamber and in proximity to a profile formed by cutting a piece of tubing, and a mechanical motion module. The plasma generator generates a plasma treatment and applies the plasma treatment via the at least one plasma head to the profile to activate material on an end surface of the profile, within a lumen of the profile, or a combination thereof. Once the material of the profile is activated by the plasma treatment, the mechanical motion module manipulates the profile to close the lumen of the profile to aseptically seal the profile.

Provided are a food container which is formed to have a sealing moiety integrated with a lid or a container body and is not easily deformed when heated by a microwave oven or the like, so as to be capable of keeping a sealed state, and a method for manufacturing the food container. A food container 10 has a container body 11 having, in the upper surface thereof, an opening 111, and a lid 12 fittable to the container body 11 to close the opening 111. In the lid 12 or the container body 11, a sealing moiety 13 is located which makes the periphery of the opening 111 in a sealed state under a situation that the opening 111 is closed by the lid 12. The sealing moiety 13 includes an elastomer composition which includes a hydrogenated styrene based block copolymer A that has a weight-average molecular weight of 100,000 to 500,000, a softener B for rubber that has a weight-average molecular weight of 500 or more, and an olefin based resin C, and which has a hardness A of 5 to 70 both inclusive, and a compressive permanent strain (CS) of 60% or less at 100° C. over 24 hours. The sealing moiety is formed to be integrated with the lid or the container body, and the lid 12 or the container body 11 includes a polypropylene.

An algae-elastomer composite including an elastomer matrix; algae; and a mixing additive sufficient to achieve a desired property. The algae can be present in a milled condition having a particle size value of between about 10 and 120 microns. The algae is mixed with the elastomer matrix in a dry condition having a moisture content of below about 10%. A method of preparing the algae-based elastomer composite is provided that includes the steps of: premixing an elastomer matrix; adding an algae filler; adding a mixing additive that includes a plasticizer; forming an elastomer-algae blend by blending the algae and elastomer to a temperature sufficient to be further mixed, wherein the temperature is about 10° C. higher than the temperature sufficient for the elastomer alone; adding and mixing a curing or vulcanizing agent for the elastomer dispersing the elastomer-algae blend; and heating and curing the elastomer-algae blend into a final form.

Systems and methods are disclosed that include generating a plasma treatment and applying the plasma treatment to end contact surfaces of a first profile and a second profile in a sterile environment, manipulating at least one of the first profile and the second profile to force contact between the end contact surface of the first profile and the end contact surface of the second profile to permanently connect, join, or weld the end contact surfaces of the first profile and the second profile together, thereby forming a sterile connection between the first profile and a second profile.

A golf club head with center of gravity proximate to the club head's sweet spot is disclosed. The golf head is composed of a strike face component made from a high-density material and a club body component made from a lightweight material. This combination improves the golfer's chances to strike the golf ball with the club head sweet spot and to land the ball closer to the hole on the green.

Provided are: a laminate having an outer surface thereof that is highly adhesive to a rubber material, and having sufficient gas barrier properties, interlayer adhesiveness and flex resistance; a multilayered structure including such a laminate; and a method for producing the same. A laminate including: a plurality of gas barrier layers (A) formed from a polymer including a gas barrier resin; and an elastomer layer (B) including at least one adhesive layer (B1), wherein a sum of number of the gas barrier layers (A) and number of the elastomer layer (B) is 5 or greater and 300 or less, the adhesive layer (B1) is laminated as at least an outermost layer, and the adhesive layer (B1) includes a styrene elastomer and is formed from a polymer having an iodine value of 200 or greater and 300 or less.

The present invention concerns an elastic fibrous material, based on a fiber network, also including an elastomeric component, which material has been formed into a flat structure with two surfaces. Further, the invention concerns a method of manufacturing said elastic fibrous material by forming a fiber network, containing an elastic polymer, foaming the fiber network, adding it into one or more layers on a support, followed by curing.

A connection includes: a first profile having a first end, the first profile including a first polymeric material comprising a thermoset material; and a second profile having a second end, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently bonded without a bonding material at an interface of the first end and the second end.

A method for the additive manufacturing of a closed-cell porous matrix is described herein. A powder-bed, additive manufacturing process is used to create a piece with partially-closed cavities filled with unfused powder. Vacuum, negative pressure, positive pressure, or solvent is used to evacuate the powder from the cavities. Finally, a fresh layer of powder is used to cover the opening of the cavity and the powder is fused on top to close the opening.
