The disposable toothbrush system is packaged suitable for sale through vending machines and that includes a tubular, plastic film, outer package, a disposable toothbrush, and a toothpaste dispensing bladder assembly. The toothpaste dispensing bladder assembly includes a seamless, non-elastic, plastic film bladder member filled with toothpaste and has a dispensing end thereof adhesively attached to an interior surface of the tubular film outer package and heat sealed and crimped between two edge sections of the first end of the tubular, plastic film, outer package.

A clamp device for connecting a high-temperature elongated component to a support comprises a first clamp mountable to the support and a second clamp for holding the elongated component. The first clamp includes a clamp holder for holding the second clamp and is made of a non-heat-resistant hard plastic material. The second clamp includes a holder for holding the elongated component and is made of a heat-resistant hard plastic material. Preferably, the outer peripheral surface of the second clamp is covered by a layer of vibration-resistant elastic plastic material that prevents transmission of vibrations between an elongated component, such as a heater pipe, and a support, such as an under floor of an automobile.

A sign holder for a retail display comprises a resilient plastic molded body. The body includes two or more resilient clasps projecting from a common base to resiliently hold a retail display sign therebetween.

A scrub brush with a handle by which the user grips the brush, a two-part scrubber portion which provides the scrubbing action, and a connecting staff between the handle and the scrubber. The scrubber may be of bristles, springy plastic mesh, rag-like or sponge material. The scrubber is designed so that a portion of the scrubber furthest from the handle can be compressed into a small diameter cylindrical shape of such dimension that a suitably sized ring of solid cleaning agent can pass over the compressed scrubber portion. When the compressed scrubber portion is released from its restraint, it expands to the original shape and size, thereby confining the ring of solid cleaning agent between the two scrubber portions.

A device for converting thermal power into electric power including a plurality of bimetallic strips disposed between a rigid support and a plate of a resilient plastic material; and on the side of the plate of a resilient plastic material opposite to the strips, a layer of a piezoelectric material connected to output terminals, wherein the rigid support is capable of being in contact with a hot source, and the plate of a resilient plastic material is capable of transmitting to the piezoelectric layer the mechanical stress due to the deformations of the bimetallic strips.

A connecting device for a plug-in connection of at least one pipeline having a housing part having at least one receiving opening for the insertion of the pipeline. A clamping ring is arranged in the receiving opening and, in order to lock the pipeline in place, interacts with an inner one of the housing part. The housing part is made in two parts including a base part and an insert part, which is connected to the base part via a snap-in action forming-fitting connection. The insert part has a direct seal for resting on the circumference of the inserted pipeline. The insert part is formed of a first relatively hard and dimensionally stable plastic material, and has a dirt seal consists of a second, relatively soft and elastic plastic material and is molded directly into the first material as a single piece with a cohesive material joint therebetween.

The invention relates to a pressure device for locking a mould. The pressure device comprises a pushing plate, wherein the pushing plate is arranged between a mould plate of a mould assembling mechanism and a corresponding mould; a clearance is reserved between the pushing plate and the mould plate; a pressure bag is arranged in the clearance; the pressure bag is made of elastic plastic material; and a metal connector, which is connected with a hydraulic device for filling a pressure medium into the pressure bag, is formed on a side wall of the pressure bag. Compared with the prior art, the pressure device for locking the mould provided by the invention can be used together with the mould assembling mechanism of related equipment, the defects of a hydraulic mould assembling mechanism, such as complex structure, high cost, low efficiency and high oil linkage probability, can be overcome. Meanwhile, the defects that a crank shaft type mould assembling mechanism is difficult to be controlled, can be easily abraded and has low precision and short service life are also overcome. In the pressure device for locking mould, the pushing plate and the pressure bag arranged between the mould plate and the mould of the mould assembling mechanism are used for replacing a traditional oil cylinder to realize a mould locking function of the mould assembling mechanism for an industrial machine, therefore the effects of high pressure rise speed and no need of lubrication can be achieved. Besides, the pressure device has the advantages of low manufacturing cost, convenience in use, low energy consumption and long service life.

The invention provides a method for determining an edge drop control regulation efficacy coefficient of cold-rolled silicon steel. By means of the method, a five-rack cold-rolled silicon steel single-taper work roller shifting rolling mill is used as a target, a minimum strip steel edge drop serves as a target function, a finite element analysis method for a silicon steel material is adopted, and by setting an elastic plastic material, arranging a contact boundary, dividing model grids, setting boundary conditions and working out N-R iteration nonlinearly, the edge drop control regulation efficacy coefficient for effectively and accurately calculating the roller shifting adjustment quantity is obtained. By adopting the method, the accuracy of the insertion adjustment quantity of a conical section of a work roller can be improved, the defect that the edge portion of strip steel is thinned is quickly and effectively controlled, the quality of finished cold-rolled silicon steel is improved, the rate of the average edge thinning value, smaller than or equal to 10[u]m, of silicon steel products can reach 100%, and the rate of the average edge thinning value which is smaller than or equal to 8 microns can reach 98.5%. According to the method, original control equipment can be used, maintenance is easy, and investment of technology import funds is reduced.

An artificial bait features an overmolded fish attractant sponge and ports through which fish attractant exudes. The bait is comprised of a soft resilient plastic. A container portion of the bait houses the sponge. The container portion includes perforations for fluid communication with the housed sponge. Prior to injection molding, the sponge is a dry compressed cellulose sponge. The sponge is coated with oil prior to injection molding. Pins or blades in the mold assembly position the oil-coated, compressed, cellulose sponge in the container portion of the bait. The pins or blades also define perforations in the container portion for fluid communication with the sponge. The oil coating on the compressed cellulose sponge prevents molten plastic from impregnating the sponge during the injection molding process. The oil coating does not cause the sponge to expand. After manufacture, a water-based fish attractant is introduced into and absorbed by the sponge via the perforations. The fish attractant may be replenished periodically.
