“HANDLE ASSEMBLY FOR CONTAINER”
We, Bajaj Electricals Limited, an Indian national, of 45/47, Veer Nariman Road, Fort, Mumbai ‐ 400001, Maharashtra, India.
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF INVENTION
The present invention generally relates to a handle for a container of a mixer grinder. In particular, the present invention relates to a handle for a container that is sturdier, longer lasting, and aesthetically appealing. 5
BACKGROUND OF THE INVENTION
This section is intended to provide information relating to the field of disclosure and thus, any approach or functionality described herein should not be assumed to qualify as prior art merely by its inclusion in this section.
10 Mixer-grinders generally include containers with means to crush or pulverise food items, and when the means are actuated, any food items within the container are accordingly processed. In order for a user to handle the container, the container is provided with a handle. Typically, the handle is a two-part handle, including an inner part, and an outer part. The inner part may be coupled with the
15 container, and the outer part may be coupled with the inner part. The outer part may serve to improve the aesthetic appeal of the handle by covering up joints and fasteners that are used to couple the inner part with the container.
However, conventionally, the inner and outer parts are made of plastic material. Plastic material may have a shorter life span. For example, the plastic
20 material may be damaged or destroyed in an event of fall of the container. For example, conventional handles may not fare optimally in drop tests, particularly the outer part of the handle becoming damaged. Further, due to constant exposure to atmosphere, and other abrasions, the outer layer may degrade, lose colour, or become disfigured, thus ruining the aesthetic appeal of the handle.
25 Furthermore, the conventional handle may be found lacking in providing a strong grip for the user to hold it, particularly when the handle is wet, thereby potentially increasing chances of the container being dropped.
There is, therefore, a requirement in the art, for a handle for a container of a mixer-grinder that may be sturdier, have an improved operational life, provide

better grip, and maintain its aesthetic appeal for the duration of its operating lifetime.

The handle 104 is made from a first material. The first
25 material includes Polypropylene co-polymer (PPCP). The handle 104 may be an inner part of the assembly 100, that is secured or coupled to the container 102. The assembly 100 includes a metal strip 106 made of stainless steel, and adapted to removably attach to at least an external surface of the handle 104. The metal strip is removably attached to at least a first exterior surface of the handle by one or more
30 screws. The metal strip is removably attached to at least a second exterior surface of the handle 104 by one or more screws.

FIG. 2A illustrates a schematic perspective view of the handle 104, according to an embodiment of the present invention.
FIGs. 2B and 2C illustrate schematic side views of a first region 110 of the handle 104, according to an embodiment of the present invention. 5 FIGs. 2D and 2E illustrate schematic top views of the first region 110 of the handle 104, according to an embodiment of the present invention.
FIG. 2F illustrates a schematic top view of the first region 110 of the handle 104, according to an embodiment of the present invention.
FIG. 2G illustrates another schematic side view of the handle 104, according 10 to an embodiment of the present invention.
Referring to FIGs. 1 to 2G, the handle 104 includes a first region 110, a second region 112, and a transition region 114 connecting the first region 110 to the second region 112. The transition region 114 includes the “neck” of the handle 104. The neck region of the transition region 114 of the handle 104 has an outer curve 15 and an inner curve, the outer curve having a first radius (r1) and the inner curve having a second radius (r2). r1 and r2 are independently in the range of 10-25mm. The transition region 114 includes a corrugation region 116, which has one or more corrugations. The height (x) of a single corrugation 116a is 3-15mm, while the height (y) of the corrugation region 116 is 10-60mm. The vertical distance (z) 20 between the bottom rib 124 and the top of the corrugation region 116 is in the range of 0-30mm.
The first region 110 includes two attaching means (118a, 118b). The attaching means (118a, 118b) mechanically attached the handle 104 to the container 102. The distance between the two-attaching means (118a, 118b) is in the range of 25 30-80mm. Extending outwards from each of the attaching means (118a, 118b), are container contact areas (120a, 120b), which are in adhesive contact with the container surface. The container contact areas (120a, 120b) feature a substantively smooth plane surface area in contact with the container surface so as to form a secure and strong bonding with the container surface and also to distribute 30 load/stress when the container 102 is dropped so as to reduce incidence of damage

to the assembly 100 and/or the container 102. In an alternate embodiment, the container contact areas (120a, 120b) are substantially reduced.
The first region 110 also includes a top rib 122, which is in continuous connection with the container contact areas (120a, 120b) and is in adhesive contact
5 with the container outer body. The first region 110 further also includes a bottom rib 124, the bottom rib 124 including a recessed U-shaped section 126 which is not in contact with the container surface. The distance between the top rib 122 and the bottom rib 124 is in the range of 10-35mm.
The span of the first region 110 of the handle 104 is the range of 40-120mm.
10 The first region 110 connects with the transition region 114 via a tapered section 115, which is defined by a curvature (r3) in the range of 20-100mm. The width of the second region 112 is in the range of 20-35mm.
The height (h) of the handle 104 is in the range of 90-130mm, while the length (l) of the handle 104 measured as extending from the container surface to the
15 part of the handle 104 which is substantially vertical, is in the range of 50-80mm. The assembly 100 may further be capable of passing a drop test. In a drop test, the assembly 100, along with the container 102 is dropped from a predefined height. The metal strip 106 of the assembly 100 absorbs a portion of the impact load, enabling the assembly 100 to withstand the impact load transmitted to it.
20 The assembly 100 may further conform to standards imposed by military grade MIL-STD-810H standards.
FIG. 3 illustrates an exemplary image 300 depicting stress distribution in the handle 104 when the handle 104 is subjected to an impact force. It may be to be noted that orange, yellow, green, and blue depicts areas of lower force in decreasing
25 order respectively. For an impact force generated by dropping the container 102 along with the handle assembly 100 from a predefined height, the handle 102 does not show any substantive areas of force concentration. In fact, the areas of the handle are majorly blue color coded, which is indicative of minimal force concentration, indicative of effective force dissipation across the handle assembly
30 100.

While the preferred embodiments of the present disclosure have been described hereinabove, it may be appreciated that various changes, adaptations, and modifications may be made therein without departing from the spirit of the disclosure and the scope of the appended claims. It will be obvious to a person 5 skilled in the art that the present disclosure may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments may to be considered in all respects only as illustrative and not restrictive.
