Description

[0001] The present invention relates to eating utensils, in particular tongs, for picking up and / or consuming food items, as well as a method for manufacturing and using the eating utensils. The eating utensils are particularly suitable for consuming small portions of food, such as snacks. The eating utensils can be used with one hand. The eating utensils can automatically return to a convenient resting position in a hygienically advantageous manner.

[0002] Eating small amounts of food between meals, often referred to as snacking, is widespread. Common snacks are typically prepared in ways that would make them more appealing, such as potato chips, peanuts, popcorn, but also, for example, various fruits, vegetables, bite-sized pieces, or similar items.

[0003] Often, snacking is desired in conjunction with another activity. Recently, snacking while using a computer, game console, smartphone, or similar devices has become increasingly popular.

[0004] When picking up snacks, the eater's hands often become soiled. This makes it difficult to use the aforementioned items, such as a computer keyboard, game console controller, or smartphone, as, for example, only one hand is available to operate the device, or alternatively, the user risks contaminating the item with food residue when touching it. This results in increased time expenditure for the user, as they have to clean their soiled hands in between tasks, and the resulting contamination is still a nuisance.

[0005] To solve the aforementioned problems associated with consuming larger dishes or meals, various types of eating utensils are available. However, these are unsuitable for snacking, as the preparation methods typically used for snacks are usually too small or fragile for conventional cutlery. It is well known that some foods, especially snacks, are therefore often referred to as finger food, meaning food intended to be eaten with the fingers.

[0006] Furthermore, it is often impossible to place familiar eating utensils down after eating a snack without ensuring that the food-contacting part of the utensil comes into contact with the surface. This is particularly disadvantageous from a hygiene perspective.

[0007] Document DE 91 01 418 U1 describes a serving set. The serving set can be placed in a bowl in such a way that the stop projecting laterally from the leg connecting the handle to the receiving section overlaps the outer edge of the bowl, thus effectively preventing the serving set from accidentally slipping into the bowl.

[0008] Document US 2015 / 0265081A1 describes a serving set. The serving set has protective elements that are connected to the respective handle section and extend vertically outwards from it.

[0009] Document DE 85 23 657 U1 describes a gripping tool. The gripping tool includes actuating projections. These projections allow, for example, the longitudinal displacement of one half of the gripping tool.

[0010] There is therefore a need for improved eating utensils that eliminate the aforementioned disadvantages and allow the user to snack easily and hygienically. The invention described herein solves these problems.

[0011] According to one aspect, eating utensils, specifically tongs, are described for picking up food. The eating utensils comprise a first arm, a second arm running essentially parallel to and opposite the first arm, and a connecting link. The first and second arms are connected to the connecting link at their respective first ends. The eating utensils are designed to allow the arms to move relative to each other, enabling the second ends of the arms, opposite their respective first ends, to be brought together. The eating utensils further include at least one protrusion on each arm. This protrusion is located between the first and second ends of each arm and extends away from the opposite arm.The center of gravity of the cutlery lies between one of the protrusions and the connecting piece. At least one protrusion of the first and second arms, along with the connecting piece, defines the points of contact when placed on a substantially flat surface.

[0012] According to one aspect, a method for manufacturing cutlery according to embodiments in a casting process, in particular a plastic injection molding process, is described.

[0013] According to one aspect, the use of eating utensils according to embodiments is described. This use includes placing the eating utensils on a substantially flat surface in any initial position, as well as the independent transition of the eating utensils from any initial position to a resting position. In the resting position, the eating utensils touch the flat surface with at least one protrusion of the first arm, at least one protrusion of the second arm, and the connecting element.

[0014] In some embodiments, the first arm runs essentially parallel to the second arm. "Essentially parallel" can also be understood to mean that the first arm is arranged at an angle to the second arm, converging towards the connecting element. This angle can be acute, for example, 0-90°, 0-45°, 0-20°, or even 0-15°. An axis lying between the first end of each arm and its second end can intersect at a point of intersection located outside both the first and second ends of the arm. This point of intersection can be located within the region of the connecting element. The angle between the first and second arms can be defined by this point of intersection.

[0015] In some embodiments, the cutlery is manufactured from a single piece. In other embodiments, the first arm, the second arm, the connecting link, and / or the protrusions are manufactured from a single piece. For example, the cutlery can be manufactured from a single, continuous piece using a suitable manufacturing method. In particular, the cutlery can be manufactured from a single piece of plastic. Suitable plastics include, for example, polyamide, polystyrene, polyethylene, polypropylene, polycarbonate, polyethylene terephthalate, or mixtures and / or copolymers of the aforementioned polymers. The cutlery can also be manufactured from other materials, such as wood, composite materials, metal, in particular metal castings or metal sheets, or the like. Advantageously, the cutlery can be manufactured from materials that are considered food-safe.In particular, the cutlery can be made from materials that are dishwasher safe.

[0016] In some embodiments, the cutlery is smooth. "Smooth" can be understood to mean that the cutlery has no corners or edges. In particular, smooth cutlery can be characterized by the fact that rounded edges are provided instead of corners and edges. "Smooth" can also be understood, for example, as meaning that the cutlery is uniquely and continuously differentiable, for example, C1-differentiable, in a cross-sectional curve, especially a cross-sectional curve along a longitudinal axis of the cutlery, such as the longitudinal axis of an arm of the cutlery.

[0017] In embodiments, at least one of the arms of the eating utensil has at least partially rotationally symmetrical areas along the axis defined by the first end of the arm and the second end of the arm in the radial direction.

[0018] In certain embodiments, the cutlery has no undercuts. Undercuts can be understood as shapes, mold sections, or design elements of the cutlery that, during manufacturing in a casting process, such as injection molding, prevent removal from the mold. Undercuts can occur, for example, in the form of openings such as holes, recesses, grooves, or the like. The occurrence of undercuts can be prevented by designing the cutlery as a single piece, smooth, and / or continuous. Examples of advantageous embodiments without undercuts are described herein, particularly with reference to the figures. The omission of undercuts advantageously enables the production of the cutlery using a cost-effective manufacturing process, especially a casting process.

[0019] In some embodiments, the eating utensil includes a spring element. This spring element can provide a spring force. The spring force can cause the eating utensil to have a defined initial position and / or be capable of assuming a defined initial position through the action of the spring. The spring force can be equal to or approximately zero in the initial position and increase when the utensil is moved from this position. The initial position can be described, in particular, by the position of the first arm relative to the second arm. For example, the initial position can correspond to an at least partially open state of the eating utensil, allowing food to be picked up in the open state. The spring force can occur or arise when the first arm is moved relative to the second arm, for example, during the normal use of the eating utensil to pick up food.The spring element can be incorporated into the connecting link. The connecting link can, particularly due to its shape, be described at least partially as a spring, for example, a bending spring or torsion spring, or be designed as such. The function of the spring element advantageously allows for simple and / or one-handed use of the cutlery, since opening the cutlery and / or returning it to its starting position occurs automatically, and the cutlery can be operated with one hand, for example.

[0020] In embodiments, the connecting element between the first arm and the second arm is at least partially annular in shape. "Partially annular" can be understood to mean that the connecting element is at least partially annular in a section of the spring element. In particular, a partially annular section can describe a circular segment and / or an arc. For example, a partially annular section can define a circular or elliptical arc in projection along an axis. The circular or elliptical arc can span an angular range of approximately 180°. The circular or elliptical arc can span an angular range of more than 90°, for example, more than 180°, such as 180°–270°. In embodiments, the connecting element can be described as an at least partially annular section between the first arm and the second arm.The ring shape can advantageously act as a spring element, for example as a bending spring, so that the connecting member includes a spring element by being at least partially ring-shaped.

[0021] In some embodiments, the ring shape can advantageously define an unstable support point, so that stable placement of the cutlery is only possible when additional support points, such as the protrusions, are engaged. For example, the ring shape can encourage the cutlery to tip over when placed in an unstable position, thus facilitating its independent transition to a stable resting position. The ring shape can offer haptic advantages for the user. For instance, it can advantageously facilitate easy tactile detection, picking up, holding, and storage of the cutlery.

[0022] In some embodiments, the cutlery set includes an opening device for opening crown caps, provided in the area of ​​the connecting element. The opening device can, for example, comprise a bottle opener and / or cap lifter of a known type and may be made, for example, from a metal part, such as a metal sheet with an opening for lifting the crown caps. The opening device can be attached after the cutlery set has been manufactured, so that a one-piece cutlery set can still be described as a one-piece set despite the attachment of the opening device.

[0023] In embodiments, a connecting element that is at least partially ring-shaped can advantageously be designed to receive and / or attach an opening device for opening crown caps. The ring shape can advantageously be both stable and flexible, making it particularly suitable for attaching the opening device.

[0024] In some embodiments, the eating utensil comprises a coating in the region of the distal ends of the first and second arms. The coating is preferably located in the area of ​​the arms intended for receiving food, for example, in the area between the protrusions and the distal ends, such as a food-holding area. The coating may include a covering, for example, a silicone coating. The coating can be produced, for example, by dip coating. The coating can be applied after the eating utensil has been manufactured, so that a one-piece eating utensil can still be described as such despite the application of the coating. Advantageously, the coating can create a smooth, food-safe surface that is particularly suitable for gripping food portions and / or easy to clean.

[0025] In embodiments, the eating utensil comprises a first arm and a second arm. The arms include a protrusion between the first end and the second end of the arm. The protrusion can divide the arm into a first region and a second region. The first region can be located on the side of the first end of the arm. The second region can be located on the side of the second end of the arm. The first region can be a holding region for gripping the eating utensil. The second region can be a food-receiving region for picking up food and / or food items. The holding region can differ from the food-receiving region, for example, in the thickness of the arms, in the cross-sectional shape of the arms, in the surface structure of the arms, or the like. Advantageously, the protrusion can separate the food-receiving region from the holding region.The protrusion can advantageously prevent food residue from "trapping" up the arms, for example, by forming a barrier, at least in sections, for the user and / or the food. Advantageously, the user can recognize simply by touch whether they are touching an area of ​​the cutlery that may be contaminated with food residue, since the protrusion at least partially prevents or at least allows the user to detect touching the cutlery in the eating area. In one example, without taking their eyes off another task, the user can first feel for the connecting element, then move their hand along the arms until they reach one of the protrusions, and safely pick up the cutlery upon feeling the protrusion.In another example, the user can pick up the cutlery at the connecting link and then let it slide down in their hand until the protrusions prevent further sliding and the cutlery is thus in a secure position in the user's hand.

[0026] The invention is described below with reference to embodiments in conjunction with the figures. The embodiments or features or aspects described in connection with them are not to be understood as limitations of the invention. Further advantageous embodiments, details, aspects, and features of the present invention will become apparent from the dependent claims, the description, and the accompanying figures. These figures show: Fig. 1A-C: An embodiment of the eating utensils in schematic side views; Fig. 2 AC: Designs of a protrusion of the eating utensil in schematic sectional views; Fig. 3 A: An embodiment of the eating utensils in a perspective side view; Fig. 3B-C: An embodiment of the eating utensils in schematic side views; Fig. 4 AC: Sectional views of the cutlery of the in Fig. 3B embodiment shown; Fig. 5A-C: An embodiment of a mold for the production of cutlery in schematic side views.

[0027] Fig. Figures 1A-C show an embodiment of the eating utensil 100 in a schematic side view. The view shown corresponds to an initial and / or resting form of the eating utensil 100. For better understanding, a coordinate system is shown, wherein Fig. 1A shows a view along the Z-axis, Fig. 1B a view along the Y-axis in a top view from the sides of the second ends 114, 124 of the cutlery set 100. Fig. Figure 1C shows a view along the Z-axis. The eating utensil 100 comprises a first arm 110 and a second arm 120. In the embodiment shown, the two arms 110, 120 are essentially parallel to each other. The arms 110, 120 each comprise a first end 112, 122 and a second end 114, 124 opposite the first end. Where reference is made herein to the direction, longitudinal axis, or axis of an arm, the longitudinal direction of an arm is generally to be understood; thus, the arms 114, 124 usually extend along their longitudinal direction. The longitudinal direction of an arm can be understood as the direction lying between the first end 112, 122 and the respective opposite second end 114, 124.

[0028] In the region of the first end 112, 122, a smooth transition of the arms into a connecting element 130 takes place in the illustrated embodiment. The smooth transition results from the fact that the Fig. The eating utensil 100 shown in Figure 1 AC is manufactured in one piece. In embodiments in which the eating utensil 100 consists of several parts, the connecting element 130 can be defined by the transition between the corresponding parts. The connecting element can, for example, comprise the area of ​​the eating utensil 100 in which the arms 110, 120 no longer run substantially parallel to each other and / or in which the arms 110, 120 no longer face each other.

[0029] As in Fig. As shown in Figure 1A, the connecting element 130 of the embodiment of the eating utensil 100 includes a section that is at least partially ring-shaped. In the embodiment shown, the connecting element 130 corresponds to a semicircular ring. Other ring shapes can also be represented by alternative arc-shaped forms, for example, arcs that can be defined as conic sections, such as elliptical arcs, parabolic arcs, or the like. The ring-shaped section can advantageously lie in a plane formed by the first arm 110 and the second arm 120. The plane can, for example, be a plane along the X / Y axes. The plane can, for example, be defined by a number of the first ends 112, 122 and / or the second ends 114, 124 of the arms.

[0030] As in Fig. As shown in Figure 1 AB, the eating utensil 100 in the illustrated embodiment is designed to be essentially symmetrical along the plane lying between the first arm 110 and the second arm 120. This plane can correspond to a plane formed along the Y / Z axes. The presence of minor asymmetries, such as the presence of a label on one side of the eating utensil, is also to be understood as essentially symmetrical.

[0031] As in Fig. As shown in Figures 1B-C, the eating utensil 100 in the illustrated embodiment is essentially symmetrical along the plane lying on the respective second ends 114, 124 of the arms and the connecting element 130. This plane can correspond to a plane formed along the X / Y axes. The presence of minor asymmetries, such as the presence of a label on one side of the eating utensil, is also to be understood as essentially symmetrical.

[0032] The in Fig. The eating utensil 100 shown in Figure 1 AC has a tong shape. In some embodiments, the eating utensil 100 can therefore be a pair of tongs. The two arms 110, 120 of the eating utensil 100 are designed to move relative to each other, allowing the end sections and / or the second ends 114, 124 of the arms 110, 120 to come together. Bringing the second ends 114, 124 together is typically used for grasping and / or picking up food items, as is already known, for example, for conventional serving or grilling tongs. Bending of the arms 110, 120, for example in the food-picking area 140 or in the holding area 150, may be possible or even desirable when the second ends 114, 124 come together, particularly when the second ends 114, 124 touch each other.A bend can, for example, cause the arms 110, 120 to not only touch at a single point of contact, but, particularly as a result of the bend, to form a contact area larger than that point of contact, so that even thin, large pieces of food, such as lettuce leaves or the like, can be picked up securely. The connecting element 130 makes it possible for the arms 110, 120 to come together. The connecting element 130 can deform slightly when the arms are brought together and provides a spring force during this deformation, whereby the spring force causes the cutlery 100 to return automatically to its original position after the arms 110, 120 have come together. Fig. 1 AC returns to the initial form shown.

[0033] The in Fig. The cutlery shown in Figure 1 AC includes the protrusions 116, 126. One protrusion 116, 126 is provided on each of the arms 110, 120. The portion of the arm 110, 120 extending from the protrusion 116, 126 towards the first end 112, 122 serves as a holding area 150. The holding area 150 is intended to be touched by the user and serves to hold and / or operate the cutlery 100. Additionally, the connecting element 130 can also be considered as a further holding area or an extension of the holding area 150. The area of ​​the arm 110, 120 extending from the protrusion 112, 126 towards the second end 114, 124 serves as the food intake area 140. The food intake area 140 is usually intended for picking up, touching or holding the food items.

[0034] As in Fig. 1 AC shown and especially in Fig. As can be seen in Figure 1B, the protrusions 116 and 126 extend in a direction away from their respective opposite arms 110 and 120. Protrusion 116 of arm 110 extends in a direction away from arm 120, and protrusion 126 of arm 120 extends in a direction away from arm 110. A direction away from the respective opposite arm can be understood as a direction that does not approach the opposite arm. For example, a direction that does not extend in the direction of the plane lying between the arms in the Y / Z direction can be understood as a direction away from the opposite arm.

[0035] As in Fig. As shown in Figure 1B, the direction moving away from the opposite arm can cover an angular range normal to the longitudinal axis of the arm, such that the direction moving away from the opposite arm covers an angular range of 180° of the respective arm normal to the longitudinal direction of the arm opposite the opposite arm. For example, the Fig. Protrusions 116, 126 shown in Figure 1B each extend along the 180° angular range leading away from the opposite arm.

[0036] In embodiments, the angular range in which the protrusion extends perpendicular to the longitudinal axis of the arm is at least 120°, advantageously at least 160°, or between approximately 160° and 180°. The symmetry of the cutlery can be maintained, so that the protrusion is also symmetrical, particularly along the X / Y plane. Due to the presence of the protrusion in the aforementioned angular range, placing the cutlery down, as described later, results in an advantageous tilting of the cutlery in any position and a transition to a stable resting position.

[0037] As in Fig. As shown in Figure 1B, the direction moving away from the opposite arm can also mean, in particular, that the sum and / or the average of the directions in which the respective protrusion 116, 126 extends away from the opposite arm.

[0038] In embodiments, the protrusions 116, 126 can be, for example, in Fig. Figures 1A and 1C, in particular with respect to the longitudinal direction of the arms, describe the protrusions as spatially limited bulges, protruding parts, projections, or overhangs. Along the longitudinal axis of the arms 110 and 120, the protrusions may, for example, be provided for less than 15% of the length of the arm, in particular less than 10%, less than 8%, or even less than 7%. For example, the length of the protrusion along the longitudinal axis of the arm may be less than 1 cm, in particular less than 0.9 cm or even less than 0.8 cm. The length of the protrusion may be defined as the length along which the diameter of the arm widens by more than 5% relative to the respective area, for example, the holding area 150 or the eating area 140.

[0039] In embodiments, the diameter of the arm 110, 120 widens by more than 20% at the outer point of the protrusion 116, 126, in particular by more than 50% or even by more than 80%. In embodiments, the diameter of the arm can increase by a factor of 1.5 to 2.5 relative to one of the areas 140, 150 along at least one direction in the region of the protrusion 116, 126, for example by a factor of 1.8 to 2.0.

[0040] In embodiments, the protrusions 116, 126 along the longitudinal axis of the respective arm 110, 120 can be described by a curve whose endpoints, connected at a further point, form a closed cross-section. The radius of the protrusion 116, 126 exceeds the cross-section on the side facing away from the opposite arm. A possible curve shape could be, for example, a sine function, a parabolic curve, a conic section, or the like. The curve can describe a smooth transition. In particular, the curve can be free of edges. The curve can, for example, be a continuously differentiable function.

[0041] In embodiments, a cross-section of the protrusions 116, 126 along the respective axis can be described as an elliptical sector or circular sector in an angular region substantially facing away from the opposite arm. Examples of advantageous cross-sections of the protrusions 116, 126 are shown in Fig. 2 AC shown.

[0042] In the Fig. In the embodiments shown in Figures 1A and 1C, the center of gravity of the cutlery 100 lies between one of the protrusions 116, 126 and the connecting element. In particular, the center of gravity of the cutlery lies in the area between the protrusions 116, 126 and the arc-shaped section of the connecting element. The center of gravity need not be located within the body of the cutlery 100. The position of the center of gravity according to the invention can be achieved, for example, by appropriately selecting the locations of the protrusions. In particular, the center of gravity can be brought into the desired area of ​​the cutlery 100 by positioning the protrusions sufficiently close to the second ends 114, 124 of the respective arms 110, 120.

[0043] As in Fig. As shown in Figure 1C, the center of gravity located between one of the protrusions 116, 126 and the connecting element 130 causes the cutlery 100 to roll, tip, and / or fall independently when placed, for example, on a substantially flat surface 170, in particular in such a way that the state of lowest potential energy defined by the center of gravity is reached. The Fig. The state shown in Figure 1C can correspond to a state during normal use, in particular during the placement of the cutlery 100. The spontaneous tipping of the cutlery 100 leads to a transition to a resting position. In the resting position, the cutlery can, for example, lie on the substantially flat surface 170. In the resting position, the cutlery touches the surface with the protrusions 116, 126 and with the connecting element 130. The resting position is stable because the center of gravity lies between one of the protrusions, in particular between the two protrusions 116, 126 and the connecting element.

[0044] In various embodiments and / or in intended use, the Fig. The resting position shown in Figure 1C is also reached when the cutlery 100 is placed in any starting position, in particular one not defined by the previously described support points. For example, placing it solely on the connecting element 130, due to the annular area of ​​the connecting element, causes it to tip over and automatically transition into the resting position. Similarly, placing it on only one protrusion 116, 126 and the connecting element 130, due to the curvature 132 of the connecting element 130 and the extension of the protrusion 116, 126 in a direction away from the respective opposite arm, also causes it to tip over and automatically transition into the resting position. If the second ends 114, 124 of the arms 110, 120 are tapered and / or rounded, as is the case, for example, in the Fig. In the embodiment shown in 3 AC, placing the cutlery 100 on its second ends 114, 124 also leads to a tipping and independent transition into the rest position.

[0045] Advantageously, the resting position is characterized by a distance 160 between the eating area 140 and the surface 170, meaning that the eating area 140 does not touch the surface 170 in a hygienically advantageous manner. Advantageously, the resting position is always the same, so that the eating utensil 100 is always available to the user in the expected resting position and can therefore be easily used, in particular felt and picked up, even by users with sensory impairments or those who are highly distracted.

[0046] The eating utensil 100 can be designed for one-handed use. One-handed usability is achieved in particular by the shape and / or dimensions of the eating utensil 100. The eating utensil 100 can have a length between the outermost point of the connecting element 130 and a second end 114, 124 of 20 to 25 cm, for example, 21 to 24 cm or approximately 22 cm. The holding area 150, in particular the area between the first end 112, 122 and the protrusion 116, 126, of at least one of the arms 110, 120, can have a length along the longitudinal direction of the arm of 7 to 12 cm, for example, 8 to 10 cm or approximately 9 cm. The food intake area 140, in particular the area between the second end 114, 124 and the protrusion 116, 126, at least one of the arms 110, 120, may have a length along the longitudinal direction of the arm of 7 to 12 cm, for example 8 to 10 cm or about 9 cm.The distance between the second ends 114, 124 in the open state, especially in the resting state of the cutlery 100, can be 3 to 5 cm, for example 3.5 to 4.5 cm or about 4 cm.

[0047] As in Fig. Figure 1 AC shows that the inner region of arms 110, 120 is flat. The inner region of arms 110, 120 can be the region of arms 110, 120 facing the respective opposite arm 110, 120. The inner region of arms can be defined by its flatness. The inner region of arms 110, 120 can be limited to a sub-region of arms 110, 120, for example, the eating area 140, the holding area 150, an area encompassing both the eating area 140 and the holding area 150, and / or the entire eating and holding area 140, 150. In particular, the inner region can also include the area of ​​the protrusions 116, 126, although the protrusions typically do not extend into the inner, flat region.A flat area in the inner region of arms 110, 120 in the food-picking area 140 can be particularly advantageous, as it can facilitate the picking up of food items. The flat area in the food-picking area 140 can make it easier to pick up many types of food, for example, rounded food portions such as peanuts. The flat area in the food-picking area 140 can result in a favorable distribution of force when picking up food portions, so that, for example, fragile food portions are less likely to break during picking up. The flat area can also advantageously lead to a favorable deformation of the arms when arms 110, 120 are brought together and the two second ends 114, 116 make contact, for example, so that a common contact surface is formed between the respective flat areas.The shared contact surface can be particularly suitable for picking up thin portions of food and can, for example, contribute to an advantageous distribution of force on the portion of food.

[0048] In Fig. 2 AC are different protrusion forms of the protrusions 116 shown in an exemplary sectional view. The representation corresponds to a section through the longitudinal axis of an arm and can, for example, be a section along the in Fig. 1 AC corresponds to the Y-axis shown. The section can be a section along the in Fig. 1 A corresponds to the section plane A shown. In Fig. In Figure 2 AC, only the protrusion 116 is shown, whereby the protrusion 126 of the opposite arm is usually also provided in a symmetrical and / or mirrored manner and / or in the shape corresponding to the protrusion 116.

[0049] Fig. Figure 2A shows a protrusion 116 with a predominantly elliptical cross-sectional profile. The predominantly elliptical cross-sectional profile is sectioned at one segment and transitions into a flat inner surface of the arm at the cut surface. The focal points of the in Fig. The protrusions shown in Figure 2A are located along the Z-axis.

[0050] Fig. Figure 2B shows a protrusion 116 with a predominantly semicircular cross-sectional profile. The predominantly semicircular cross-sectional profile transitions into the arm at the cutting edge of the profile, i.e., the flat edge of the semicircle. The center of the circle lies on the flat inner surface of the arm.

[0051] Fig. Figure 2C shows a protrusion 116 with a predominantly elliptical cross-sectional profile. The foci of the ellipse lie along the Y-axis. The predominantly elliptical cross-sectional profile corresponds to an ellipse divided at its midpoint perpendicular to the axis of the foci of the ellipse.

[0052] The section profile transitions into the arm at the cutting edge of the section profile. The center of the ellipse lies on the flat inner side of the arm.

[0053] The in Fig. The protrusions 116 shown in Figure 2 AC can advantageously allow the cutlery 100 to roll along the outer edge of the protrusion 116, 126. This facilitates the transition to the resting position. The Fig. The protrusions 116 shown in Figure 2 AC define support points in the rest position on which the cutlery 100 advantageously rests. The protrusions 116 and 126, together with the connecting element 130, define support points for the cutlery. The protrusions 116 and 126 and the connecting element 130 of the cutlery 100 can be the only support points for the cutlery 100, particularly in a rest position, especially in a rest position such as that which the cutlery 100 assumes on a flat surface.

[0054] In Fig. Figure 3 AC shows different views of a particularly advantageous embodiment of the eating utensil 100. The Fig. The 3 AC cutlery set shown (100 pieces) includes many features or aspects already associated with Fig. 1 AC described embodiment, so that it will not be discussed in detail thereafter.

[0055] As in Fig. As can be seen in Figures 3 A and B, the connecting element 130 of the cutlery 100 is designed as a circular arc. The arc spans an angle of approximately 280°. The outer surfaces of the connecting element are rounded. This rounding facilitates the advantageous tilting of the cutlery. When manufactured from a single material type, such as one of the previously described polymers, the rounding also allows for an advantageous spring effect in the connecting element 130. This advantageously eliminates the need for additional springs.

[0056] As in Fig. As can be seen in Figure 3B, the arms 110 and 120 in their respective holding area 150 have essentially the same cross-sectional profile as the connecting element 130. The longitudinal cross-section of the arms 110 and 120 is curved on the side facing away from the opposite arm in the holding area 150. The cross-sectional profile of an arm 110 or 120 in the holding area 150 is shown in Fig. Figure 4A shows the details. The cut surface is shown hatched; the other elements shown are the surfaces of the cutlery 100 behind the cut, viewed along the Y-axis from the second ends 114, 124 towards the connecting element 130. Due to the same cut profile, the arms 110, 120 exhibit essentially the same bending properties as the connecting element 130, so that the arms 110, 120 can also bend in the area of ​​the holding section with the spring effect described in connection with the connecting element 130. Bending the arms 110, 120 in the area of ​​the holding section 150 can be advantageous, for example, if the second ends 114, 124 of the arms 110, 120 are to touch at a point and further compression of the cutlery 100 in the holding section is intended to form a common contact surface in the food receiving area 140.Furthermore, the cut profile shown in the connecting element 130 and in the holding area 150 allows the user to pick up and hold the product in a particularly favorable way, is haptically advantageous and is also easy to hold in different grip positions.

[0057] In various embodiments, the following are Fig. 3 AC shown, arc-shaped, away sides of the arms and / or the connecting link are designed in areas circular, elliptical or in the form of a curve that can be described as a conic section.

[0058] A sectional view of protrusions 116, 126 of the in Fig. The cutlery shown in section 3 AC is described in detail in Fig. 4B is shown. The cut surface is shown hatched; the other elements shown are the surfaces of the cutlery 100 lying behind the cut when viewed along the Y-axis from the sides of the second ends 114, 124 towards the connecting element 130. The cut profile of the protrusions 116, 126 essentially corresponds to the shape of the in Fig. Protrusion 116 shown in Figure 2B. Additionally, protrusions 116 and 126 are slightly rounded in the transition area to the flat, inner area of ​​arms 110 and 120. This prevents sharp edges that could, for example, scratch surfaces when the product is placed down.

[0059] As in Fig. Figure 3 AC shows that the arms 110, 120 in the food-receiving area 140 of the cutlery 100 are shaped differently than the holding area 150. The arms 110, 120 are reinforced in the area of ​​the protrusion 116, 126 in the direction away from the opposite arm compared to the holding area 150. This prevents deformation in this area, so that any bending of the arms occurs primarily in the area of ​​the holding area 150.

[0060] The arms 110, 120 taper progressively along their longitudinal direction in the food-picking area 140 towards their second ends 114, 124, terminating in rounded tips, which define the respective second end 114, 124 of the arm. This tapering of the arms in the food-picking area 140 towards their second ends 114, 124 allows for the picking up of food items of varying sizes and shapes. For example, small food items can be grasped precisely with the thin tips, while larger or heavier food items, intended for consumption in several bites, can be picked up in the central area of ​​the food-picking area 140. The central area of ​​the food-picking area 140 provides a larger and / or more stable contact surface for the food item.

[0061] In Fig. 4C is a cross-section through the food intake area 140 of the in Fig. 3 AC shown cutlery 100 shown. The cut can be a cut along the in Fig. 3 B corresponds to the plane C shown. The cut surface is shown hatched; the other elements shown are the surfaces of the cutlery 100 lying behind the cut when viewed along the Y-axis from the sides of the second ends 114, 124 towards the connecting element 130. As in Fig. As can be seen in Figure 4C, the cross-sectional profile of the arms 110, 120 in the food intake area 140 essentially corresponds to a triangle, with one face of the triangle forming the inner surface of the arms and one apex of the triangle pointing away from the opposite arm. Due to the tapering of the arms 110, 120 towards their second ends 114, 124, the arms in the food intake area 140 can thus be described, at least partially and / or approximately, as an oblique pyramid with a triangular base, the triangular base being located in the area of ​​the protrusion 116, 126. As in Fig. As can be seen in Figure 4C, the edges of the arms 110, 120 in the food-handling area are slightly rounded. Additionally, the tips at the second ends 114, 124 of the arms 110, 120 may also be slightly rounded, so that the cutlery has no sharp points. This rounding avoids sharp edges and / or points that could adversely affect the usability of the cutlery, especially when eating food, and increases the safety of the cutlery.

[0062] The in Fig. 3 AC and Fig. The shape of the arms 110, 120 shown in Figure 4C in the food-holding area is particularly advantageous because the triangular cut surface and / or the pyramidal shape of the arms provide a rigid food-holding area 140 with an advantageous contact surface between the two arms 110, 120, while requiring little material. At the same time, the center of gravity of the cutlery 100 is advantageously located closer to the first ends 112, 122 of the arms, which also allows the protrusions to be positioned closer to these first ends 112, 122.

[0063] In embodiments, the food intake area at a contact point of the first arm 110 and the second arm 120 facing the opposite arm is at least partially designed as a flat section, wherein the flat section in particular includes the second end 114, 124 of the arm.

[0064] In embodiments, the protrusions 116, 126 do not impede the joining of the planar section of the first arm 110 and the second arm 120. In particular, the protrusions 116, 126 do not extend in the direction of the planar section.

[0065] As in Fig. As can be seen in Figure 3 AC, the eating area 140 of the cutlery 100 includes an internal, flat area of ​​the arms 110, 120 along its entire length. The protrusions 116, 126 do not impede the bringing together of the arms. Thus, the internal, flat area of ​​the arms 110, 120 can form a contact surface along the entire eating area 140 when the arms are brought together. Any bending of the arms 110, 120 occurs primarily in the gripping area 150, so that the arms first touch at their distal ends 114, 124, and then, with further bringing together of the arms 110, 120, the formation of the contact surface is possible. Due to the described behavior, the cutlery can be particularly suitable for picking up various food items, as both a point grip (at the tips) and a surface grip (at the internal contact surfaces) are possible.

[0066] In the embodiments, a method for manufacturing eating utensils is described. The method may include a casting process, in particular a plastic injection molding process. Known plastic injection molding processes can be used for manufacturing the eating utensils.

[0067] To manufacture a set of cutlery 100 according to an embodiment described herein, a material such as plastic is injected into a multi-part injection mold. A suitable mold 500 is in Fig. Figure 5 AC shows that the mold 500 consists of two first parts 510 and two second parts 520. The two first parts 510 define the outer shape of the cutlery 100, in particular the area of ​​the cutlery 100 that is not located within the two arms or the connecting element of the cutlery. The two second parts 520 define the inner area of ​​the cutlery 100, in particular the area of ​​the cutlery 100 that is located within the two arms or the connecting element, such as the common contact surface. In embodiments, a single second part 520 can be used instead of two second parts 520. The first parts 510 and the second parts 520 can each be designed to be largely symmetrical. Advantageously, the design in Fig.The arrangements of parts 510 and 520 shown in Figure 4 AC, forming a mold, do not result in any undesirable burrs on the outer surfaces of the cutlery, such as would occur, for example, if the method for manufacturing the cutlery involved casting in two molds divided along the X / Y plane. Since parts 510 and 520 form a mold in which the finished workpiece, i.e., the cutlery 100, has no undercuts, the workpiece can advantageously be manufactured in a single operation.
