A bag container including a synthetic-resin container body shaped by using a mold and including a spout-forming portion and a filling inlet portion that project outward therefrom. Contents are first filled through the filling inlet portion, and then fusion-bond sealing is applied to the filling inlet portion. The filling inlet portion has, at its sealing base portion, a square cross-sectional shape. A tip-end-side cross-section-changing portion and a cylindrical portion are provided on the tip-end side with respect to the sealing base portion. Four triangular panels each isosceles triangle shaped are connectedly provided on the side of the container body with respect to the sealing base portion along a circumferential direction of the filling inlet portion, a base of each isosceles triangle formed of one of sides of the square cross-sectional shape. When the fusion-bond sealing is to be applied to the filling inlet portion, a region on the tip-end side with respect to the sealing base portion is folded flat while positioning a pair of opposing corners on opposite edges of the filling inlet portion.

A method of producing a fiber molded article using a pressing mold, includes inserting a first split and a second split into a slurry tank such that a fiber layer is formed on the first split and a fiber layer is formed on the second split, placing the pressing mold, which includes a solid elastic member and an inflatable elastic member configured to be inflated, onto the fiber layer on the first split, joining the first split and the second split such that a fiber molded article is formed from the fiber layer on the first split and the fiber layer on the second split, and dewatering and shaping the fiber molded article by pressing the fiber molded article by the solid elastic pressing member and the inflatable elastic pressing member.

Production mold for formed fiber

A molded article () made predominantly of pulp and comprising a bottom portion () and a body portion (), wherein the angle &#x3b8; between the outer surface of a side wall of the body portion () and the ground contact plane (B) of the bottom portion () is 85&#xb0; or greater, and the height of the body portion () is 50 mm or more.

Formed body

A pulp molded container comprising a pulp molded article () having on the inner surface and/or the outer surface thereof a resin layer () with a thickness of 5 to 300 &#x3bc;m formed by applying a coating, wherein the thickness ratio of the resin layer () to the molded article () (former/latter) is 1/2 to 1/100, and the surface roughness profile of the outer or inner surface of the pulp molded article is such that a centerline average roughness (Ra) is 0.5 to 20 &#x3bc;m.

Pulp molded container

Disclosed is a method of producing a fiber-molded hollow article by using a papermaking mold () composed of splits () which are joined to form a cavity () having two openings () connecting with the outside and an expandable pressing member () adapted to be placed in the cavity (). The method comprises the steps of immersing each of the splits () before being joined in a fiber slurry to form a fiber preform (), joining the splits () each having the fiber preform () formed thereon while placing the pressing member () in the cavity (), and molding and dewatering a molded article () in the papermaking mold ().

A prescribed molded substrate is molded out of a melted resin with a stamper having projections for forming pits with the shape of the projections preliminarily set to be greater than the shape of pits of the substrate to be molded. The relationship between the height H of the projections for forming the pits to the stamper and the depth d of the molded substrate is such that H/d=1.3 to 1.8.
