A three-dimensional object includes an outer-layer member and an inner structural member. The outer-layer member is a layer to constitute the surface of the three-dimensional object, and includes an inner space. The outer-layer member is made up of a plurality of divided outer-layer pieces formed of build material, which is functional ink ejected from a droplet ejection head and cured. The inner structural member is disposed in the inner space of the outer-layer member and configured to support the outer-layer member.

A pipe coupling for triple wall corrugated plastic pipe includes a triple wall corrugated bellmouth connector that is of a unitary construction with one end of the corrugated plastic pipe. This bellmouth connector is of higher strength and in cooperation with the two wall corrugated spigot provides a high strength coupling. This coupling includes the bellmouth connector and spigot that are made inline with the corrugated pipe. A method for the manufacture of the pipe includes controlling of an air pressure on the outside of a formed two wall corrugated pipe as an exterior third wall is secured thereto.

A composite product having a junction structure includes a first unit formed of a composite material, a first connector formed of a metal and provided with one end inserted into one end of the first unit and formed integrally with the first unit and another end extending outwards from the first unit, a second unit formed of a composite material, and a second connector formed of a metal and provided with one end inserted into one end of the second unit and formed integrally with the second unit and another end extending outwards from the second unit, wherein the other end of the first connector and the other end of the second connector are joined and fixed by welding under a condition that the ends of the first unit and the second unit are opposite each other adjacently.

A container is formed to include an interior region and a mouth opening into the interior region. The container includes a floor and a side wall coupled to the floor to define the interior region between the floor and the side wall.

An insulated sleeve is provided to be coupled to an outer surface of a cup. The sleeve is formed from an insulative cellular non-aromatic polymeric material having an area of plastic deformation. There are no fractures in the insulative cellular non-aromatic polymeric material so that a predetermined insulative characteristic is maintained in the material.

A joint structure according to an embodiment of the present invention is provided with: a first member that is made of a metal material and has a plurality of holes having an opening diameter of 30-100 μm formed in a surface thereof; a third member that is made of a metal material the same as or different from that of the first member, or a thermoplastic resin, and that has a plurality of independent holes having an opening diameter of 30-100 μm formed in a surface thereof; and a second member that is made of a curable resin and joins the surface of the first member in which the holes are formed and the surface of the third member in which the holes are formed.

A method for producing a component from two or more sub-components includes the steps of: producing each of the sub-components using an additive manufacturing process in which a resin, which is radiant-energy-curable, is partially cured using a selective application of radiant energy, wherein each sub-component includes a joint surface in which the resin is partially cured which is cured to a lesser degree than the remainder of the respective sub-component, so as to leave the joint surfaces in a condition suitable for bonding; assembling the sub-components with their respective joint surfaces in mutual contact; and performing a secondary cure of the partially-cured resin at the joint surfaces using an application of radiant energy, so as to further cure the partially-cured resin and bond the sub-components to each other, thereby forming the component.

Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

A process for continuous welding of a sheet of plastic material for manufacturing flexible packages, comprising a step of positioning the sheet relative to the welding device, putting ends of the sheet into contact, forming a weld by heating, pressing and cooling the ends of the sheet that are in contact, acquiring a primary temporal signal with a sensor, the primary temporal signal proportional to a thickness of the weld, transforming the primary temporal signal into a primary frequency signal and defining a low-frequency spectrum, a medium-frequency spectrum, and a high-frequency spectrum from the primary frequency signal, reconstructing a secondary low-frequency signal from the low-frequency spectrum, and determining the thickness of the weld based on the secondary low-frequency signal.
