Golf ball methods and molds for quickly and efficiently eliminating air/gas from within a mold while better centering a subassembly in the mold during golf ball manufacture and the improved golf balls resulting therefrom.

A molded product in which a parting line can be disposed at an inconspicuous position on the appearance of the product. The molded product includes a main body having a cylindrical shape and a hole penetrating through the main body in a radial direction, or a protrusion protruding in the radial direction from the main body, and in the molded product, a parting line corresponding to a matching surface of molds is formed in the molded product, and the parting line has a first line extending from the hole or the protrusion to one side in a circumferential direction of the main body, and a second line extending from an end point on the one direction of the circumferential direction of the first line to an end portion in an axial direction of the main body.

In order to prevent shaft portion from being broken in ejection of base portion from mold, method for manufacturing interdental cleaning tool includes: base portion forming step of forming base portion by filling first space of primary mold (50) with synthetic resin, which includes first and second mold members (50A, 50B); and cleaning portion forming step of forming cleaning portion around shaft portion by filling second space of secondary mold with elastomer. Base portion forming step uses first and second mold members (50A, 50B). First and second molds include: first and second contact surfaces (51A, 51B); pair of first and second spaced-apart portions (54A, 54B); and first and second connection portions (52A, 52B), angle (θ) between each of first and second spaced-apart portions (54A, 54B) and separation plane being acute.

A suction valve stem, a suction valve, an endoscopic valve kit, and a method for molding a stem are provided. The suction valve stem includes: a button head, and a stem body connecting to the button head. The stem body includes: an air passage through the center bore, a recessed slot, disposed on the stem body below the button head and above the side opening, a sealing area, disposed on the stem body below the side opening, and a flat, disposed on the stem body. The air passage includes a side opening disposed on side surface of the stem body and a bottom opening disposed at a bottom end of the stem body. The recessed slot is disposed 90 degrees from the side opening. The flat is disposed 90 degrees from the side opening and has a fluid communication to the bottom end of the stem body.

The present invention is directed to a golf ball having a non-planar parting line on its spherical surface.

A thin-walled flexible package (1) is provided with a spout (6) comprising a connection portion (12) and a tube (18) having an outer surface (18e) and ending with an outlet mouth (20). A sacrificial closure (200) is applied to the spout (6) to close the outlet mouth (20). The sacrificial closure (200) comprises a skin (202) suitable for sealing engaging the outer surface (18e) of the tube (18) at a scaling region having a scaling distance (H) from the outlet mouth (20). On the outer surface (18e) of the tube (18) there is a circumferential dividing line (L2) having a division distance (H2) from the outlet mouth (20). The scaling distance (H) is less than the division distance (H2).

The present invention is directed to a mold for forming the cover of a golf ball having a non-planar parting line on its spherical surface.

A component of a mold for molding preforms made of thermoplastic material, comprising

at least a first part (10) and at least a second part (20) adapted to mold part of the outer surface of a preform,

wherein, when the first part (10) and the second part (20) are assembled to each other, at least a first surface (11) of the first part (10) and at least a second surface (21) of the second part (20) face each other and are spaced apart from each other, thus delimiting a passageway for gases or vapors to leave the mold;

and wherein at least one of said first surface (11) and said second surface (21) comprises laser-induced periodic surface structures (LIPSSs).

An aerator mixing rod includes a body having a first and second opposite ends and an outer surface extending between the ends. The body defines a longitudinal axis extending through the ends. The aerator mixing rod also includes teeth extending radially outward from the outer surface, with a first row of teeth and a second row of teeth spaced from the first row along the longitudinal axis. A first passageway is formed between adjacent teeth of the first row, and a second passageway is formed between adjacent teeth of the second row. The first passageway is at least partially misaligned with the second passageway in a direction parallel to the longitudinal axis such that the first passageway and the second passageway form a tortuous path for fluid flowing along the outer surface of the body. The aerator mixing rod is formed from an injection-moldable material by an injection molding process.

A roller is capable of smoothly rotating without any burr on a rolling surface. A dish washer including the roller includes: a case; a basket configured to accommodate dishes; a rail configured to guide the basket to be put into or taken out of the case; and a basket roller coupled with the basket and configured to move along the rail, the basket roller comprising a rolling portion configured to roll in contact with the rail, a first flare portion extending in a first direction from the rolling portion, and a second flare portion extending in a second direction from the rolling portion, the second direction being opposite to the first direction, wherein a diameter of the first flare portion is greater than a diameter of the second flare portion.
