As used herein the specification and in the claims section that follows, the term "powder" and the like refer to a substantially solid material including grains, with the typical size of a grain similar to the standard typical size of a grain of sugar used for sweetening tea and coffee in domestic use or a smaller typical size.

The utensil and method for collecting and pouring powders and fluids according to the present invention are based on a principle including clean and precise collection of powder or fluid on one side of the utensil, transferring the material collected through a tube, and conveniently and precisely pouring it out of the other side which is designated for pouring or dripping.

The powder can be powders such as, but not exclusively, types of sugar, coffee, and spices, and the fluids can be fluids such as, but not exclusively, water, sauces, liquid condiments, and sweeteners. The principle of the invention can be applied in many fields and can be used in a variety of environments and with a wide age span.

Referring now to the drawings, Figure 2 is a perspective view of utensil for collecting and pouring powders and fluids 100 according to the present invention.

The external design of utensil 100 appears as a unified cylinder, elongated and curved, reminiscent of the form of a gourd, starting at one end with rounded contours of a certain width and tapering towards its other end, which is trimmed. The lateral sections of the cylinder can have many shapes, ranging from simple circular or elliptical shapes of varying sizes, through shapes that vary with the progression from one end to the other, to sections of other various complex shapes. Usually, unless a specific need requires another form, the cylinder will be symmetrical relative to a symmetry plane. The unique form of utensil 100, with an opening for collection of liquids and powders open at an upper external surface on its wide end, the front, enables collection of powders and liquids from containers of a narrow and deep form or through relatively narrow openings, followed by carrying them and pouring them into another container, or dispersing them over a defined surface. This illustration shows that holding handle 2 can have an arched shape. The illustration also clearly shows collection container 1 with an entry opening.

Figure 3 is another schematic illustration of a perspective view of utensil for collecting and pouring powders and fluids 100 according to the present invention. This illustration shows discharge opening 3. Utensil 100 is built as a single unit, to which a virtual Cartesian coordinate system is fixed, two axes of which, X axis and Y axis, define a plane which is horizontal plane, while utensil 100 is disposed such that the Z axis, the third axis of the Cartesian coordinate system, is inverse to the direction of the local gravitational force of the earth, defining the side of the utensil 100 referred to as the upper side.

The two axes, X axis and Z axis, define a plane which can serve as the symmetry plane of the utensil 100.

Precise collection of powder or liquid by means of utensil 100 can be done for a fixed defined volume according to the volume of container 1 or for smaller volumes if measurement markings 9 or any other suitable means of indication are disposed on the inner wall of container 1 or even its outer wall, if the container is completely or partially made of translucent material.

Measurement markings 9 can be made at different angles, with regard to the coordinates. The user can thus choose an inclination angle, with regard to the horizon, of

utensil 100 which is adapted to the most convenient way to hold utensil 100. Measurement can be done by means of groups of suitable measurement markings 9. The illustration shows two groups of measurement markings 9 each at a different angle with regard to coordinate X. The markings of each group can be made differently, for example in different colors. In order to enable collection of a precise fixed volume of powder or fluid that is other than the volume of a full container, one internal marking can be made in container 1. This marking can be a groove, paint, or any other suitable marking, and can be continuous or fragmented on the entire circumference of container 1 or part of it. Particularly when collecting fluids, high precision can be achieved when, during measurement, utensil 100 is positioned in a spatial orientation such that said marking is perpendicular to the local gravitational force. This is easily done by aligning the plane of the marking with the plane of the surface of the fluid.

Figure 4 is a schematic illustration of a top view of a utensil for collecting and pouring powders and fluids 100 according to the present invention. Even though utensil 100 is a single unified body, it is composed of three main parts: collection container 1 with a top opening that can be disposed on a plane approximately parallel to X - Y plane, collection container 1 is attached to holding handle 2 in which a tube is disposed, one opening of which is disposed in a suitable place on the wall of container 1, with a discharge opening not shown in the illustration disposed on the other end of the holding handle. Figure 5 is a schematic illustration of a side view of a section of a utensil for collecting and pouring powders and fluids 100 according to the present invention. The section is along line a-a shown in Fig. 4. This section illustrates the internal tube 8 connecting the collection container 1 with the discharge opening 3 enabling the passage of powders and fluids. The illustration shows the upper curve 5 and lower curve 6 formed by the section plane in the internal tube 8 and the distance between them at a certain point, marked as D.

According to a preferred embodiment of the present invention, in order to enable smooth and efficient flow within the internal tube 8, these section lines are continuous and without points of discontinuity, including their points of connection to the collection container 1, and can be expressed as mathematical functions. This continuity without any points of discontinuity is maintained throughout the entire surface encasing the space through which the flow occurs.

As used herein the specification and in the claims section that follows, the term "continuous" and the like refer to a substantially conventional definition of a mathematical function f(x) at a point x 0 , and likewise a point of discontinuity is a point at which a function is not continuous. An additional controlling influence, also increasing the velocity granted to the flow within the internal tube 8, is achieved by means of a gradual decrease in distance D progressing towards the discharge opening 3.

The lateral section of the internal tube 8 can have a fixed shape which only changes in size progressing from the collection container 1, such as an ellipse with a fixed radii ratio, but can also be a varying form, such as an ellipse with a varying radii ratio. At the point where internal tube 8 has a circular cross section, its circumference is D.

As shown in the illustration, holding handle 2 has a curved form, with a varying curve on the section plane.

The utensil for collecting and pouring powders and fluids 100 has an upper external surface which also includes the upper external surface of the holding handle 2. When this upper external surface is crossed by virtual plane X-Z, which can serve as the symmetry plane for utensil 100, a curved line is formed, being the curve of the upper external side of the section of the upper external surface 7. Seeing as holding handle 2 is curved, the tangents to this line at both of its ends form angle Alfa between themselves. This angle will be referred to as the inclination angle of the utensil in the present patent application.

Likewise, we will refer to the angle between the tangent on the end of discharge opening 3 and the plane formed by discharge opening 3, as the discharge opening inclination angle Beta.

The entry opening of the collection container is an open hole in the upper external surface. When collecting material into the collection container 1, some of it enters the curvature of the holding handle 2, which enables the collection of material without unwanted spilling of the material though the discharge opening 3. This curvature is essential in order to enable slow pouring at a well-controlled rate. Furthermore, the curvature of the discharge opening 3 is significant for convenience of use and holding, seeing as its curved shape has a clear advantage over a direct tube which is not well adapted to the arched form of the human hand. This convenience enables good control and applying delicate motion.

Selection of the shapes and dimensions of the various parts of the utensil for collecting and pouring powders and fluids 100 can be reached by trial and error, and can be adapted for collection from containers of specific shapes and dimensions, for transferring material to containers of specific shapes and dimensions, at relative locations and specific distances between containers, as well as to various sizes of users.

Furthermore, the illustration shows front lip 4 of the collection container 1. This lip helps prevent the loss of material after collection. Front lip 4 can be designed with a slight inclination upwards, forming a wider and more efficient lip to prevent spilling of powder or liquid during use, namely making the opening smaller relative to the wider section area of the collection container. This inclination enables the return of material from the walls inward, by deflecting material that is sprayed outwards.

The illustration also shows that the end of the holding handle 2 with the internal tube 8 is diagonally crossed by section plane. This section forms a discharge opening 3 with an area larger than that of the section area perpendicular to the flow. The wide diagonal opening enables wider dispersal of the flowing material when desired, by means of shaking. Without shaking, the pouring is free and precise.

An additional advantage of this form is achieved when cleaning the discharge opening 3. Seeing as the opening is relatively wide, it is easy to clean, and dirt is always accumulated outwards on the tip of the pouring lip. Figure 6 is a schematic illustration of three separate steps: a, b, and c, which demonstrate the method of use of the utensil for collecting and pouring powders and fluids 100 according to the present invention.

In step a, the user holds the utensil 100 in his hand 30 and collects powder or fluid 20 into the container 1, from the initial storage container 10. In step b, the user moves utensil 100 with the collected substance inside the container.

In step c, the user tips utensil 100 with his hand 30, so that the powder or fluid 20 is poured into the second storage container 11. According to the degree of tipping, the rate of the flow of powder or fluid 20 is determined, namely, strong and fast flow can be achieved when there is no need for controlled discharge of powder or fluid 20 from utensil 100, as well as slow flow when control is required, such as in the case that a small amount of powdered spice needs to be dispersed over a relatively large area.

The utensil and method for collecting and pouring powders and fluids according to the present invention has many advantages, some of which are:

No spilling or dripping of the powder or fluid on the way from the first container to the second container. Powders and fluids can be taken from containers placed on high shelves or inaccessible locations without seeing their contents.

Powders or fluids can be taken from deep containers without tilting them or holding them by hand.

Salt, sugar, or dressing can be dispersed on salads and foods in a uniform manner, with slow dripping.

The utensil also has clear advantages in fostering fine motor skills and spatial perception in children.

Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
