9 results about "Rigid collar" patented technology

A milk collection vessel with a flexible sidewall and a rigid collar may be attached either to a lever-operated breast pump assembly or to a passive breast pump assembly. The lever-operated assembly has a vessel tube axis offset from the vessel axis to make the lever easier to operate with a small hand. The breast flange of the passive breast pump assembly is formed of an elastomer and, prior to application to the breast, may be everted with the aid of manual tabs.

The present invention discloses a zero-axis drift multi-cross flexible hinge, comprising a left cross flexible body group, a right cross flexible body group, ten bearing rods with the same structure, and left and right collars with the same structure. The bearing rods are alternately distributed at equal angles in the positive and negative directions in the circumferential direction, the inner surfaces of all the bearing rods are located on the same cylindrical surface, and the length direction of the bearing rods is parallel to the center line of the cylindrical surface. The outer surface of the thick end of the bearing rod and the inner surface of the collar are located on the same cylindrical surface, and the two end faces of the bearing rod are respectively located on the same plane as the end face of the collar. The flexible body connects the two bearing rods in the radial direction, and is distributed at equal angles in the circumferential direction and at equal distances in the axial direction. The zero-axis drift multi-cross flexible hinge has the same axis drift in the five directions. Under the action of the rigid collar, the axis drift in the radial direction cancels each other out, and the ideal rotation center of the rotating end does not change, thereby achieving zero-axis drift.

A spray cleaning device includes a bottle made of a resilient material and a cap with a compression nozzle is provided. Squeezing the resilient bottle forces contained fluid through a channel in the nozzle, dispensing a stream at increased pressure and velocity. In some embodiments, the bottle includes a annular shoulder that supports a rigid collar. The rigid collar provides external threads for the cap and a rigid foundation for a compression seal. An opening of the bottle may be defined by an integrated gasket at the distal end of the neck. The resilient neck may allow the rigid collar to be passed over the integrated gasket during assembly. When the cap is tightened, it applies axial force to the integrated gasket against the collar, and in turn against the shoulder, to create a fluid-tight seal.

The disclosure generally relates to adjustable sheath devices for insertion into the body to provide intravascular access to various medical devices, involving a dynamically expandable sheath capable of expanding within the blood vessel when a medical device is passed through the sheath and retracting back to almost its original size when the medical device is removed from the sheath. Embodiments generally comprise a rigid collar and an elongated sleeve comprising a continuous elastomeric outer layer and an expandable inner layer.

A pack (1) for smoking articles having: two groups (5) of smoking articles; two sealed wraps (2), each enclosing a respective group (5) of smoking articles and having a smoking article extraction opening (6) and a re-stick closing label (7) overlapping the extraction opening (6); a container (3), which houses the two sealed wraps (2) arranged side by side and is provided with a hinged lid (4); and a rigid collar (14), which is connected inside the container (3) so as to engage a corresponding inner surface of the lid (4), when the lid (4) is arranged in the closed position, and has two side walls (16) and a front wall (15) provided, at the top, with a through opening (18) delimited by a "U"-shaped edge. The extraction opening (6) of a sealed wrap (2), arranged on the right, has a different shape or a different position than a shape or a position of the extraction opening (6) of a sealed wrap (2), arranged on the left.

The invention provides a rock expansion performance testing device and method.The rock expansion performance testing device based on the original geological conditions comprises a testing instrument and a lantern ring assembly, the lantern ring assembly comprises a rigid lantern ring body and a flexible confining pressure unit, and the confining pressure unit is arranged in an inner ring of the lantern ring body; the confining pressure unit is provided with the pressure cavity, a sample is placed in the containing cavity defined by the confining pressure unit, fluid is conveyed into the pressure cavity through the pressure adjusting unit, pressure is applied to the sample in the lateral direction, on one hand, the confining pressure borne by rock under the original geological condition can be simulated, and the result measured in a test room is closer to the real situation; on the other hand, the side swelling amount of the expansive rock sample can be reduced or eliminated, and the accuracy of test results is improved.

A fastening system for fastening a distribution member, such as a pump, on a neck of a reservoir to form a distributor for a fluid product includes a fastening ring and a rigid collar, the ring including a skirt intended to be engaged around the neck. The skirt includes articulated fastening tabs angled outwards with respect to a central axis X of the ring, and the collar is able to be moved with respect to the skirt and engaged around the skirt so as to fold back the articulated tabs to a radial alignment with the axis X. The ring with the collar is then able to be assembled on the neck and able to be disassembled from the neck without relative movement between the ring and the collar, and the articulated tabs have an internal fastening means that can engage with an external fastening means of the neck.

A fluid product dispenser having a vessel and provided with a neck forming at least one helical thread, and a dispensing head mounted on the neck of the vessel, the head having a dispensing member and a fastening member engaging both with the threaded neck and the dispensing member The fastening member has a deformable and malleable skirt intended to engage with the threaded neck, and a rigid collar engaged around the skirt to push the skirt radially against the threaded neck in such a way as to deform the skirt against the thread so as to create a thread imprint in the skirt. The helical thread has an intermediate portion that has, on at least some of its length, a cross-section that decreases in the unscrewing direction and increases in the screwing direction, such that the unscrewing torque decreases and the rescrewing torque increases.

A milk collection vessel with a flexible sidewall and a rigid collar could be attached to either a lever-operated or a passive breast pump assembly. The lever-operated assembly has a vessel tube axis that is offset from the main axis to make it easier to operate the lever with a small hand. The breast flange of the passive breast pump assembly is made of an elastomer and can be inverted using manual tabs before application to the breast.
