A two-piece induction seal for use in creating clean, safe, and secure inner seals on containers having a monolayer plastic formed from synthetic fibers with stable pore dimensions for fluid permeability while retaining dimensional stability for compression. An inductive innerseal membrane is provided having a first side and a second side thereof, with an adhesive layer at the first side of the membrane. The second side of the membrane is detachably bound to the synthetic material with a wax layer. The synthetic material is further suitable for absorbing substantially all of said wax layer when said wax layer is in liquid form.

Left-handed and right-handed twist tip cleaning devices for cleaning left and right ear canals of a user comprise a shaft having a soft twist tip head which is positioned over a hemisphere type end of the shaft which is supported by two angled inwardly legs. The soft twist tip head has six flutes encircling a bullet shaped body along the longitudinal axis of the shaft. The flutes of the left-handed twist tip cleaning device differ from the right-handed twist tip cleaning device by angling the flutes to optimize cleaning of the ear canals when rotated by the user. A tickler extends from the top of the twist tip head to provide a safety warning when the tickler contacts an ear drum. A storage box comprises a plurality of left-handed twist tip cleaning devices in one-half of the box with one end removably hinged to an edge of the box. A second half of the storage box comprises a plurality of right-handed twist tip cleaning devices removably hinged to an edge of the box.

A machine room (15) is provided between a cab (14) and a counterweight (6) which are mounted on a revolving frame (5) to accommodate an engine (7). The machine room (15) is built of a left front support member (20), a rear support member (21), a connecting support member (22) and a left side housing door (25). A horizontal grip portion (22B) and an inclined grip portion (22C) are provided in intermediate portions of the connecting support member (22) which connects the left front support member (20) and the rear support member (21). By opening the left side housing door (25), the inclined grip portion (22C) of the connecting support member (22) comes out, permitting a servicing worker to hold on thereto helping him or her perform a cleaning job of a rear face portion (14B) of a cab (14) in an efficient manner.

An endoscopic cleaning device capable of properly removing wet cerumen from an auditory canal while the interior of an auditory canal is illuminated. The device allows an image of the interior of the auditory canal to be acquired while the auditory canal is being cleaned. The device has an ear picking main body that also serves as a light guide to provide the illumination. The ear picking main body rotates about a light guide containing the micro lens used to acquire the image, so that the image remains stable. The ear picking main body is inserted through a removable, elastically deformable tubular ear picking part having a through hole and an outer layer made of fibrous material. In this way light can be delivered to the end of the ear picking main body, and the fibrous material of the ear picking part can be used to remove wet cerumen.

A hand held dusting apparatus for use with a motor provided with a rotating axle, such as a variable speed drill, includes an elongated extension member attachable at one end to the rotating axle and a dusting member having a body section attachable to the opposite end of the elongated extension member and a dusting section constructed having multiple strands of synthetic fiber materials extending from the body section. In a preferred embodiment the apparatus further includes a tubular hand guide member fitted about the extension member and constructed to slide along the extension member. In another preferred embodiment the body of dusting section has a mid-section that can be pivoted to allow the dusting elements to rotate about an axis set at an angle to the axis of the extension member.

The invention relates to a cleaning device, in particular to a pet cleaning device. The technical purposes that by means of the pet cleaning device, time and labor are saved, cleaning is fast, in thecleaning process, a pet can be fixed and does not influence cleaning conducted by people, and the cleaning effect is good are achieved. In order to achieve the technical purposes, the pet cleaning device comprises a bottom plate and the like; struts are mounted on both the left side and the right side of the front and rear of the top of the bottom plate, the struts are symmetrically arranged, a fixing device is arranged among the top ends of the four struts, and a cleaning device is arranged among the upper portions of the four struts. According to the pet cleaning device, by means of a blowing device, impurities and dust on the pet can be removed, meanwhile, the pet feels cooler and easier to be cleaned, so that the effects that time and labor are saved, cleaning is fast, in the cleaningprocess, a pet can be fixed and does not influence cleaning conducted by people, and the cleaning effect is good are achieved.

It is an object of the present invention to provide a transformerless charger capable of preventing a human body from receiving an electric shock from a charging terminal, and of making it easy to clean the charging terminal. In order to achieve this object, the transformerless charger of the present invention comprises: a charging terminal for supplying charging voltage to rechargeable electronic equipment; a transformerless power supply circuit for supplying charging voltage to the charging terminal; a flip cover that covers the charging terminal to prevent the charging terminal from being exposed; and a switch that allows or blocks the passage of a current between the charging terminal and the transformerless power supply circuit in synchronization with an opening or closing motion of the flip cover. This configuration makes it possible to control the passage or blocking of a current at the charging terminal in response to the open or closed state of the flip cover, and therefore, it is possible to secure safety to prevent a human body from receiving an electric shock via the charging terminal and it is also possible to easily clean the charging terminal.
