A container having a cylindrical pouring nozzle with an external thread and with a stop; a cap with an internal thread which can be screwed onto the external thread of the pouring nozzle as far as an end position in which the cap bears in the direction of rotation on the stop of the pouring nozzle; and a seal made of a material which is softer than a material of the cap and a material of the pouring nozzle. The seal is fixedly connected to the cap and has a first sealing element which, with the cap screwed on, is arranged in a radial direction between the cap and pouring nozzle and bears on a lateral surface portion of the pouring nozzle.

A closure cap for a detergent bottle, the closure cap including at least one cap wall having a plurality of surface elements spaced apart from one another. The surface elements each have a circumferential edge, starting from which the particular surface element extends from a datum plane of the cap wall, and which surrounds a base of the surface element located in the datum plane of the cap wall. In order to form a smooth transition from the datum plane that does not have a notch effect, a radius of curvature is provided at the circumferential edge that is larger than the largest longitudinal extent of the base of the surface element.

To provide a plastic cap that can be safely applied to a closed system drug transfer device, prevents the leakage of a drug from a pharmaceutical container, and does not require a plurality of connection adapters when fitting to a medical instrument of the closed system drug transfer device.

There is provided a plastic cap attached to a pharmaceutical container and fitting to a medical instrument used for a closed system drug transfer device, the cap includes a top surface part having a fitting part at the center thereof, a cylindrical skirt part extending downward from an outer periphery of the top surface part and opening at a lower end, and a fitting member fitting inside the skirt part, in which the fitting part includes a lip and an intermediate tube extending downward from the lip, and the skirt part has a lower rubber stopper there inside and the lower rubber stopper has an O-ring shape.

A container having a cylindrical pouring nozzle with an external thread and with a stop; a cap with an internal thread which can be screwed onto the external thread of the pouring nozzle as far as an end position in which the cap bears in the direction of rotation on the stop of the pouring nozzle; and a seal made of a material which is softer than a material of the cap and a material of the pouring nozzle. The seal is fixedly connected to the cap and has a first sealing element which, with the cap screwed on, is arranged in a radial direction between the cap and pouring nozzle and bears on a lateral surface portion of the pouring nozzle.

A plastic bottle cap includes a plastic cap body. The bottom side of the cap body is an opening, and the inner wall of the cap body near the bottom side opening of the cap body is annularly provided with a groove. The sealing ring is installed in the groove, and one side of the sealing ring extends to the outside of the groove. The annular groove is opened around the inner ring of the bottle cap body. Two semi-circular rings are movably mounted in the annular groove, one end of the two semi-circular rings is rotatably connected by the first hinge, one end of the two semi-circular rings which far away from the first hinge is fixed with the first fixing block and the second fixing blocks respectively, and the first fixing block and the second fixing block correspond to the setting.

A container (1) and a screwable closure (2) comprising a hollow body (11) and a neck finish (10) terminated by a wide-mouth opening (100). Said neck finish comprises a neck support ring (102) and a neck portion (101) extending between the wide-mouth opening (100) and the neck support ring (102). The neck portion (101) comprises an upper portion (1010) and a reinforced lower portion (1011). The inner face (1011 b) of the reinforced lower portion (1011) is transitioning to the inner face (1010b) of the upper portion (1010) along a transition step (1011c) in such a way that said reinforced lower portion (1011) is thicker than the upper portion (1010) at least in a top part of the reinforced lower portion (1011). The neck support ring (102) is below the removable closure (2).

The present invention relates to a tank cap including a lever member that is constrained from moving to the standing position contrary to the intention of the operator. The tank cap comprises a slide member disposed in the cap body so as to be adjacent to the lever member, and provided with a cam contact portion that is to come into contact with a cam portion of the lever member, and a coil spring disposed between the slide member and the bottom of the cap body. The resilience of the coil spring causes the cam contact portion to press the cam portion and retains the retracted position.
