A cover for a valved dispensing closure prevents the valve from opening while the cover is disposed on closure. The cover's central projection prevents flaps formed in the valve from opening, and the cover's outer projection prevents the flexible valve head from moving or inverting. The cover may also have projections that project inwardly from its skirt. The cover projections interact with mating projections formed on an exterior of the closure, and a lower end of the skirt may be disposed into an annular groove in the closure, to enhance a seal between the closure and the cover. The cover may include a snap ring attached to other portions of the cover by a breakable connection to provide tamper evidence.

The insert (12) has a second portion extending radially outwardly and including a mating projection (28) for engagement with the outer shell projection (34) to form an inner circumferencial volute wall portion. A backplate (14) has a third projection (38) adjacent its outer circumference that is received in a relief (40) in the outer shell (10) and completes the outer circumferencial volute wall portion. The outer shell projection (34) has a first land (70) engaging a second land (72) on the mating projection, the first and second lands (70, 72) spirally descending relative to a datum (45) and the relief (40) has a third land (76) in spaced relation to a fourth land (74) on the third projection (38), the third and fourth lands (76, 74) spirally descending respectively relative to the datum (45).

A fluid filled type vibration damping device wherein an outer tubular mounting member is externally fitted onto the collar sleeve at an externally fitted section formed by a tapered tube portion of the outer tubular mounting member, by means of a diameter reduction process. A mating projection projecting diametrically inward is formed on an inside peripheral face of the outer tubular mounting member, while a seal rubber layer having a thickness greater than a projecting height of the mating projection is formed covering the inside peripheral face of the outer tubular mounting member with the mating projection covered by the seal rubber layer. A location and projecting height of the mating projection are arranged so as to prevent an entry of another outer tubular mounting member into a large-diameter opening of the tapered tube portion during pre-treatment.

A disc cartridge accommodating an optical disc in a cartridge body. This disc cartridge is provided with a cartridge body formed by mating and joining a pair of upper and lower halves formed at the circumferential edges with rising circumferential walls which are mated to each other to constitute the circumferential side walls and, at the same time, formed at facing inner surfaces with walls for forming the accommodating portion which are mated to each other to constitute the disc accommodating portion in which the optical disc is accommodated. This cartridge body is provided with openings for recording and reproduction and a shutter member for opening and closing these openings. On the two sides of the cartridge body on the lower half from the front side toward the middle toward the back side are provided recess portions for preventing erroneous loading. A plurality of fusing portions for mating and fusing the upper and lower halves are provided at positions corresponding to these recess portions.Each fusing portion for mating and fusing the upper and lower halves is provided with a mating projection formed at one of the upper and lower halves and a mating projection formed at the other. A plurality of mating projections formed at either half comprise mating projections having projections for fusing annularly and continuously formed over the entire circumference of the end surfaces to be mated to the mating projections of the other half and mating projections having projections for fusing formed in the form of an arc in one part of the end surfaces.

The invention relates to a high-frequency connector socket and a processing method thereof, comprising a socket seat with a socket, and the outer circumference of the socket seat is coaxial with the outer circumference of the pin seat of a pin inserted into the socket. The center is the same size, and a ring of inserting bosses are arranged on the inner side of the opening of the jack. Slots are set on the wall of the socket to meet the impedance matching requirements of high-frequency connectors and ensure the continuity of electrical transmission. The depth of the socket is less than 85% of the socket depth, which can effectively prevent stress from concentrating on the end of the socket and improve the service life. The length of the slot is inversely proportional to the contact pressure of the socket and the pin. The length of the slot meets the insertion force requirements of the socket and the pin, and at the same time reduces the contact resistance. The socket is fatigue-resistant and prolongs the service life.

A reversible vacuum filter cartridge for connection to a pair of tubes or other entities to filter a liquid medium placed in one of the tubes or other entities is described. The filter cartridge is comprised of a male coupling and a female coupling. The couplings are interconnected to one another by simply pushing a mating projection of the male coupling into a mating cavity of the female coupling. A connecting port is provided in the male and female coupling and has a conduit communicating with tube connecting ends of each of the couplings which communicate with an open end of a tube connected to each of the couplings. The connecting port is identical in each of the couplings and serves either as vacuum port or an air intake port. A filter disk is retained captive between perforated outer walls of each of the couplings when interconnected together in fluid-tight relationship.
