Mixing-bowl assembly

Abstract

A bowl assembly includes a main bowl having a spherical outer surface, a removable median extension having a spherical outer surface and a lid having a protruding grip profile. The main bowl is made of an opaque plastic material in the form of a spherical zone having a silicone sealant applied to a bottom of the main bowl to ensure stability of the bowl assembly during use and which is provided at a top with four “L” shaped grooves. The removable median extension is open at a top and a bottom thereof is attached to the main bowl and is made of transparent plastic. The removable median extension is joined with the main bowl by sliding protrusions and grooves. Positioned above the removable median extension there is the lid which has a grip profile.

Mounting Example

(25) The utility model comprises a spherical opaque plastic bowl (4) having a silicone sealant (5) applied to the bottom of the bowl to ensure the stability of the assembly during operation and which is provided at the top with four “L” shaped grooves, profiled on the inside of the top edge of the main bowl, positioned diametrically opposed and at equal distances between them (7), over which a removable median extension in the form of a spherical area open at its top and bottom (3) is attached, made of transparent plastic, which is provided with four protrusions diametrically opposed and at equal distances between them, located on the outside of the lower edge of the median extension (6). Above the removable extension a plastic lid (2) is positioned, which has a three-dimensional protruding grip profile (1) resulting from its configuration. The entire assembly is characterized by the ratio of the H1 height of the bowl assembly to the D1 diameter of the sphere of the bowl assembly, H1/D1 in the range 0.8-0.9, the ratio of the H2 height of the bowl (4) to the H1 height of the bowl assembly, H2/H1 in the range 0.6-0.7, and the ratio of the H3 height of the median extension (3) to the H1 height of the bowl assembly, H3/H1 in the range 0.4-0.3.

(26) Closing between the parts of the bowl assembly is achieved by a known gripping system, by sliding four protrusions (6) positioned diametrically opposed and at equal distances between them, located on the outside of the lower edge of the median extension, in four “L” shaped grooves (7), profiled on the inside of the top edge of the main bowl, positioned diametrically opposed and at equal distances between them. The joining of the parts together to form the bowl assembly is illustrated in the details of FIGS. 9, 10, and 11.

(27) In order to ensure an effective closure, as shown in FIG. 6, the upper edge—the “lip”—of the bowl (4) and the lower edge of the spherical median extension (3) have the special configurations shown in FIGS. 5, 7, and 8, forming a known gripping system. The top edge of the bowl (4) has four “L” shaped grooves (7) profiled on the inside, positioned diametrically opposed and at equal distances between them. The spherical median extension (3) has on the outside of its lower edge four rounded protrusions (6) positioned diametrically opposed and at equal distances between them. The diameter of the four protrusions (6) is smaller than the width of the grooves (7), and the joining of the spherical main bowl—the base of the assembly (4) and the spherical removable median extension (3) is achieved by sliding the four protrusions (6) into the four grooves (7) by a press-and-twist motion of the median extension (3) on the bowl (4).

(28) In one embodiment, the various plastic elements could be made of a heat-resistant plastic. Similarly, in one embodiment, the silicone sealant could be a heat-resistant sealant.
