Abstract: [Problem] To protect a leading end part of a drill having a coolant hole which is adapted for drilling a thin diameter or very thin diameter hole in a workpiece. [Solution] A coolant hole 33 is formed in a shank 3 and a shaft body 7 so as to extend through from a rear end surface 31 of the shank 3 to a leading end surface 15 of the shaft body 7 along an axis thereof. A leading end part of the coolant hole 33 is branched into a pair of discharge holes 35, at a position slightly toward a base end relative to the leading end surface 15 of the shaft body 13. The discharge holes 35 extend in the opposite directions, perpendicular to the coolant hole 33, respectively, and open at opposite side surfaces 37, 37 to define discharge ports 39, 39. A leading end opening 41 of the coolant hole 33 is closed by a bottom face 17 of the drill part 9.

Abstract: A fluid injection assembly for a combustion engine may comprise a spring clip arranged between an injector body and an injector cup. The spring clip may include a ground plate and at least one spring element fixedly coupled with the ground plate. The spring element has a contact region with the injector cup and the ground plate has a contact region with the injector body, so that a spring force is exerted by the spring clip on the injector body. The injector body and the injector cup are coupled together by two holding elements, each of the holding elements extending in the direction of the longitudinal axis and engaging behind a fixation element.

Abstract: A product includes a container including a neck, and a fitment having a portion coupled to the neck of the container via an interference fit.

Abstract: A product includes a container including a neck, and a ring non-removably secured to the neck of the container. The ring may be used to non-removably couple a fitment to the container and/or may be adapted irreversibly to change a characteristic of the ring that is visible from outside of the container to advise a user that the package has been opened.

Abstract: A tamper-evident closure for a container is provided. The closure comprises a first portion including inner and outer parts, and a second portion. The outer part is rotatable relative to the inner part from a first position in which at least part of the first and second portions are adjacent each other to a second position in which there is a gap therebetween. The first portion comprises locking means for irreversibly locking the closure in the second position upon a first opening so that the gap cannot be closed. The inner part includes a line of weakness which breaks if the outer part is reverse rotated relative to the inner part.

Abstract: Anti-filling device to be attached to the neck of a bottle to be closed by a sealing cap, including attachment means for attachment to the bottleneck, a chamber including a lower lip surrounding a lower orifice and confining a moveable part which forms a valve in conjunction with the lower lip, and an axial distribution duct. The device further includes a moveable axial rod, secured to the anti-filling device, the axial movement of which relative to the device is limited between a low position and a high position, and at least one stopper which is in engagement with the moveable axial rod such that, when the moveable axial rod is located in the low position, the stopper shuts an orifice which is arranged in the chamber. The low position is imposed by a projection attached to the cap, which comes into contact with the moveable axial rod when the cap is attached to the bottleneck.

Abstract: An anti-refilling device, designed to be fixed irreversibly to the neck of a container containing a liquid and to be closed by a stopper cap. The device has an axis coinciding with the axis of the neck when it is fixed on the neck, and has an axial dispensing duct for the liquid through which a transverse wall extends, fixed irreversibly to the anti-refilling device and provided with a plurality of traversing channels, each of the channels connecting an external opening, directed towards the outside of the container, to an internal opening, directed towards the inside of the container. The smallest dimension of the external opening is less than a critical dimension determined according to the critical surface tension of the material making up the transverse wall, typically about 0.7 mm, and the smallest dimension of the internal opening is greater than the critical dimension.

Abstract: A one-way stopper plug for bottles and the like, comprises a one-piece resilient plastic molding consisting of two mating halves joined to each other by an integral living hinge whereby the entire unit can be molded in one operation. Each half has a semi-cylindrical wall and two transverse walls at its ends, said walls having planar edge portions adapted for co-engagement when the halves are folded together, thereby to form a complete cylinder. The living hinge connects two of the transverse walls together. The mating halves define a channel therethrough, and a back-check valve disposed in the assemblage operates to limit fluid flow in only one direction. Forcing the assembled halves into a bottle neck maintains them in their assembled relation.

Abstract: A security stopper or other closure for a bottle comprises a valve which rests upon its seat except when the contents of a bottle are to be poured out through the stopper which thereby serves as a dispenser. The valve and seat arrangement is located at the lower portion of the plug-like body, the upper portion of which is provided from top to bottom with an upper baffle, an intermediate grill and a lower baffle to prevent access to the valve by a tool inserted through the pouring spout of the dispenser and thereby precluding refilling by dislocation of the valve.
