Peripheral portion of filters includes short-side portions and long-side portions. A first component and a second component each include a first holding section and a second holding section, the long-side portion of the filter being compressively held between the first holding sections, and the short-side portion of the filter being compressively held between the second holding sections. At least one of the first component and the second component includes a wall portion configured to isolate the long-side portion and the resin from each other. The short-side portion and the resin are in contact with each other.

There is provided a manufacturing method for molding a liquid supply member by using a first mold and a second mold in which the first mold is capable of being slid relatively to the second mold, the method including a first molding step of performing injection molding to form a first and second component parts of the liquid supply member at different positions from each other, an evacuating step of sliding the formed second component part in a direction intersecting with a direction of sliding of the first mold relative to the second mold and with a direction of the opening and the closing the first and the second mold, a contacting step of bringing the formed second component part into contact with the molded first component part, and a second molding step of performing injection molding to join the first component part and the second component part.

A blown bottle includes at least two layers including an inner layer and an outer layer, wherein the inner layer includes an inner layer flange, the outer layer includes an outer layer flange, and wherein a protrusion is formed on either one of the inner layer flange or the outer layer flange, a recess is formed in the other, and the protrusion is fitted to the recess.

A blow bottle includes an outer layer and an inner layer, wherein the inner layer has blackness higher than that of the outer layer, and wherein the outer layer has an L* value of 20 or more and 90 or less in an International Commission on Illumination (CIE) L*a*b* color system.

First and second constituting components are injection-molded and joined within one pair of molds. In order to join the first and second constituting components, one of the respective regions of the first and second constituting components abutted to each other is pushed into the other.

A mold includes a rotatable portion, a frame portion, a first and second portion, and a production unit. The rotatable portion has a plurality of surfaces and a plurality of forming portions. The plurality of surfaces is each provided with one of the plurality of forming portions, each having the same shape. The frame portion rotatably supports the rotatable portion. The first portion defines a cavity by coming into contact with one surface of the plurality of surfaces by clamping the mold. The second portion comes into contact with another surface of the plurality of surfaces different from the one surface by clamping the mold. The production unit attached to the frame portion.

An inkpad holder for arrangement in an insertion compartment of a self-inking stamp includes a one-piece body having a bottom and walls projecting therefrom which delimit a receiving space for receiving an inkpad. At least one wall of the inkpad holder has a retaining web protruding into the receiving space in order to retain the inkpad, the retaining web extending over the entire length of the wall.

A method for producing a blow-molded article, the method comprising: a step of producing a preform from a resin mixture comprising at least a wax, a thermoplastic polyester and a carbodiimide compound; and a step of blow-molding the preform to produce a blow-molded article.

A stretch blow-molded article comprising: a first polyester; and a second polyester having a structure different from a structure of the first polyester, wherein an intrinsic viscosity value of the first polyester is 0.60 to 0.74 dL/g, and the second polyester has a structure corresponding to terephthalic acid and a structure corresponding to bisphenol A.

Provided is a method for manufacturing a liquid-ejecting head whereby in die slide injection molding it is possible to stably inject resin in secondary molding without damaging the shapes of parts that were formed in primary molding. In order for that, in the connecting section in which a convex section of a cover member is inserted into an opening of a liquid-supply member, the closest distance to the opening in the area where secondary resin is injected is made larger than the gap between the opening and the convex section. As a result, the resin is prevented from flowing into a liquid path during the secondary molding.
