A collapsible container has four panels that fold down on a base for storage. The base has slide sockets with vertical slots. Front and rear panels pivot on the base with slide hinges received in the slide sockets. The panels are able to slide up and down. A hinge pin has a narrowed waist portion to engage a latch. Left and right panels pivot with snap hinges received in snap sockets on the base. Trunnions, disposed in the snap sockets, are eccentric to increase or decrease the backlash between the snap hinge and the snap socket as the panels pivot.

The present invention provides a golf ball comprising a golf ball body with a spherical core having one or more layers, an intermediate layer disposed outside the spherical core and a cover disposed outside the intermediate layer and a paint film formed on a surface of the golf ball body, and having a friction coefficient calculated using a contact force tester of 0.35 or more and 0.60 or less, wherein the golf ball body has specific plurality of dimples on the surface thereof, at least one layer of the spherical core is a rubber layer having a specific hardness distribution, and the rubber layer has a hardness at the outermost point which is greater than a hardness at the innermost point, and the intermediate layer has a slab hardness (Hm) which is greater than a slab hardness (Hc) of the cover.

An endoscopic instrument has a control member, a portion of the member having an outer surface with a non-circular cross-sectional shape. The non-circular cross-sectional shape may be provided to the control member by providing peripheral projections or fins along the length of the portion or by providing the periphery of the portion with a polygonal shape. Where fins are used, the fins are preferably quite small and only have a minimal effect on the fluid flow cross-sectional area between the interior of the endoscope instrument shaft and the central control member. The resulting instrument has significantly reduced backlash in end effector assembly manipulation, while maintaining adequate fluid flow in the endoscope shaft. According to a second embodiment of the invention, a portion of the interior of the shaft of the endoscopic instrument has an interior surface having a non-circular cross-sectional shape by the inclusion of a plurality of radially spaced and inwardly directed ribs or by being polygonally shaped. The resulting endoscopic instrument likewise reduces the backlash experienced in operating the distal end effector assembly.

An animal feeding structure can include one or more openings to drain water that is sprayed into the feeding structure in order to clean it. By draining the incident water, the remaining dirt, food and other particles are drained and removed from the feeding structure, thereby cleaning the structure without direct handling. Also, because the water is drained, water bounce back onto the person cleaning the bowl can be greatly reduced. The feeding structure can include an opening covered by a raised cap whose clearance from the bottom of the bowl can be adjusted. The feeding bowl can also include lateral and/or longitudinal slits of various sizes and shapes. The size and shape of openings can be designed to prevent food from falling out while allowing water, food crumbs, dirt, and debris to drain out. The effective size of the openings can be adjusted.
