A lid assembly and a knife adapted to be attached to a jar, the lid assembly including: a cylindrical jar sleeve adapted to be secured to the open end of the jar and having a jar sleeve circumferential portion at the upper end thereof. The lid assembly also includes a lid adapted to be removably attached to the jar sleeve and having a lid circumferential portion, one of the lid and jar sleeve having a groove adapted to receive the circumferential portion of the other of the lid and jar sleeve.

A buckle joint structure has a first body, a second body and a buckle module with a cross section of a C-shape. A first flange of the first body is fixed or buckled to a second flange of the second body via the buckle module with the cross section of the C-shape. When assembling, merely a sliding manner is required to make the first flange of the first body and the second flange of the second body buckled to the buckle module. When detaching, merely a sliding manner is required to withdraw the buckle module away from the first body and the second body. Thus, the buckle joint structure is easily assembled or detached without an extra tool or help of another person.

The present application discloses a centering aid for a container having a container trough, with an access opening, a container lid and a seal. In the closed state of the container, the seal is arranged between the container trough and the container lid. The centering aid has a first centering device, which is provided on either the container lid or the container trough, and a second centering device, which is provided on the other of either the container lid or the container trough. The first and second centering devices interact in such a way as to ensure that, in the closed state of the container, the seal is in contact with the container trough and with the container lid along the entire periphery of the access opening.

The present invention relates to a fluid delivery assembly for a spraying apparatus. The assembly comprises an outer cup, a lid having a fluid outlet adapted to couple the lid to the spraying apparatus, and a liner for holding paint. The fluid delivery assembly comprises an interlocking keyed geometry adapted to prevent rotation of at least one of the lid and the liner with respect to the cup. The interlocking keyed geometry comprises at least one of (a) at least one protrusion of the cup extending into at least one recess of the lid, and (b) at least one protrusion of the lid extending into at least one recess of the cup, wherein the liner is trapped between the protrusion and the recess. The invention also relates to liners for such fluid delivery assemblies, which may be provided as a set of liners having different inners volumes.

A drop lid-shaped formed lid to be fittably applied to a container having a flange section is formed with a flange, a fitting section extending downwardly from the flange, and an introducing section below the fitting section. The introducing section is composed of first and second tapered sections whose inner diameters each decrease downwardly. The taper angle of the second tapered section is larger than the taper angle of the first tapered section, and the second tapered section is formed in an arcuate shape smaller than a range in which the first tapered section is formed.

A cap for a container comprises an annular collar with a longitudinal axis and a diameter perpendicular thereto. A seal includes two seal elements which cooperate to form a generally cylindrical seal member locatable in the collar with the seal elements in contact with each other in a plane parallel to the longitudinal axis. At least one of the seal elements has at least one opening therethrough. The openings are configured to receive the tubes of a medical tube set and the cap can be constructed with different combinations of seal members to provide a different number of openings into the container.
