A personal care implement includes a treatment device having a longitudinal axis and including a treatment portion having at least one treatment element; a connection portion having a main body and a first resilient snap attachment protruding from the main body, the main body formed of a first material having a first hardness and the first resilient snap attachment formed of a second material having a second hardness, the first hardness being greater than the second hardness; and the treatment device is alterable between: (1) a detached state; and (2) an assembled state in which the treatment device is detachably coupled to a grip section such that the first resilient snap attachment cooperates with and engages a first engagement portion of the grip section to secure the treatment device to the grip section.

Oral care implement

A multi-well plate assembly has a well plate with a plurality of closed-bottom, open-top wells of substantially uniform square cross-section between the closed bottom and the open top. An insert plate is nested with the well plate and has a top wall substantially covering the open tops of the wells. Inserts project down from the top wall and into the respective wells, such that each insert is nested in a corner of the well. Access ports are formed through the insert plate for alignment with a corner of the respective well opposite the insert. The access port is formed partly through the top wall of the insert plate and partly through the sidewall of the insert.

Multi-well device

A multi-well culture dish assembly is provided which includes an insert having rows of frustoconical enclosures and a well plate in which the enclosures are suspended. The insert includes a top wall having a peripheral flange, the enclosures being integral with and extending downwardly from the top wall. Each enclosure includes a radial opening which extends into the upper portion of the enclosure. Rows of openings are formed in the top wall of the insert, and respectively adjoin the radial openings in the enclosures. The relatively large pipette openings are formed by the adjoining openings. The well plate may include rows of cylindrical wells. The enclosures are positioned within the wells and are radially offset with respect thereto. The openings within the top wall of the insert are in registration with the wells when the insert is mounted to the well plate.

Cell insert for a tissue culture plate

Apparatus for growing cells or tissue in vitro and for supporting, positioning and/or centering cell culture inserts that are used in such procedures. The apparatus comprises a body with a plurality of wells wherein a cell culture insert may be supported and centered without interfering with the growing of tissue culture in vitro.

Culture vessel

This invention involves racks or tray arrays for use in clinical laboratories, in particular, to support tubes and other containers holding body fluid specimens. The invention allows the user to 'build' racks or arrays of larger and/or smaller capacity, depending upon the user's requirements, by rapid snapping together of a plurality of identical modular tube units. The racks or units may have a variety of size openings for accommodating different size specimen containers, and containers of different configuration. Thus, the user can maintain stable support of a great many containers simultaneously for handling in the laboratory, thus avoiding the danger of dropping or spilling specimens. The arrangements of the invention may be comprised of reusable, autoclavable moldable plastic materials, or less expensive throw away moldable materials. The individual components making up the tube rack array may be of a variety of geometric configurations.
