Abstract

The beaker for hot drinks or foods is double-walled (2, 3) in the area which is normally held. This can be identified, e.g. by contouring the walls.

Description

The Innovation concerns a container for hot drinks and Food, which is preferably made of porcelain or the like solid material. In a second preferred embodiment it consists of a semi-solid material such as cardboard, plastic or edible Material, and is therefore suitable for single use. It's mainly supposed to do this serve from it hot drinks or eat soups by closing the palm (s) directly around the jar. It is in addition in the contact areas double-walled so that the fingers do not burn, but on the contrary, comfortably warmed become.

The following Vessels are known to eat hot content:

• a. Mugs and other vessels with handles: touching them on the handle requires balance and strength and is difficult for some groups of people (This becomes particularly clear when used by children and old / sick people). Operation must be learned. It also says the handle is far off and can be a hindrance when stowing in the closet be (risk of breakage).
• b. Drinking bowl, glass and other single-walled vessels without Henkel: Touch in the area of the upper edge possible (also hot there, danger of Burning fingers due to spillover). Or: Hold between thumb and second finger, on the bottom ring and on the Top edge. (Difficulty: lifting off the table).
• c. Vessel with a coated Insulation sleeve made of other material (e.g. made of felt): Direct touch in the cuff area possible. Disadvantage: insulating ring can slip, gets dirty, may need to be removed when washing up different aging process of different materials.
• d. Disposable cup or other container with a foam insulation layer along the entire vessel wall, or as a whole from a foamed Made of material. Recyclability problem, not a defined one Handling area.
• e. Disposable plastic cups with lamellas in the upper edge area. (For soups, "five-minute terrine"). Slats act as a spacer for the fingers and thus form a contact area. But this is not clear due to the ring-like arrangement at the top of the cup recognizable as a contact surface. Has a purely technical function, does not allow enjoyment of hand warming, nor of enclosing with the hands. Gives no secure hold.
• f. double-walled vessel (made of metal, Porcelain, ceramics, earthenware, plastic and other materials). Gap hollow or filled with liquid. optical Effect often clumsy or large, because the entire circumference is double-walled. The insulating effect will not made visible, or, for example, advertised as a thermal mug only for the content. The fact that the vessel is safe with the hands is not communicated, often such drinking cups even have Handle. (Example G 85 18 647.3 "thermally insulated drinking cup")
• G. Mug with attached rubber knobs. For disabled people. Pimples all over Vascular mantle, none Marking of certain contact areas, very special material composition and area of application.

At the Drinking hot drinks the problem with normal cups or drinking bowls is that you can easily burn your fingers if you put the jar directly includes. Therefore, different manipulations have become common - as with we usually touch cups on a handle, or in the Orient frequently attacking tea glasses on the top edge and bottom between the thumb and index finger.

there the direct encirclement of the vessel brings decisive advantages in terms of balance / least effort, and in Terms of sense for the Content temperature: the heat cannot be estimated there is a risk of burning your mouth. Additionally improved such direct handling the aspect of sensual enjoyment, because it is natural, corresponds to intuitive gripping behavior, and still there the hands of hot vessel contents are warmed can.

The Innovation is based on the task of a container for hot drinks and Propose food,

• - the touched safely in a direct manner and can be included
• - whose Function is communicated by means of the form, so that the operation self-declared
• - the enables a haptic experience when used, including warming the hands
• - the consists of a single solid and food-safe material
• - the in big enough Areas is single-walled, so the temperature of the content On contact well rated with the lips can be.

To achieve this object, a container for hot drinks and food is proposed, which is characterized in that it is double-walled only in the contact areas. These areas are recognizable as such from the outside and are designed in such a way that they are raised areas ( 1 ) running parallel to the core container ( 2 ) the. There is a gap between the outer wall of the core container and the contact surface ( 5 ) of a few millimeters, which provides thermal insulation by means of an air layer. The exact distance varies depending on the vessel size and material, it is 1–6 mm for smaller vessels (e.g. bowls, cups) and up to 20 mm for larger vessels (e.g. serving bowls).

Characteristic is not just the presence of a double-walled contact point, but above all their shape and size, which - depending on the type of vessel - can be found on the ergonomically based support surface the touching body part oriented, usually according to the contour and size of an overlying palm. This will later described in more detail.

Execution: In the preferred embodiment, the contact surface is firmly connected to the core container. The connection is made at as few points as possible so that the heat conduction to the contact surface is reduced to a minimum - for example by a small number of webs ( 8th ), which are connecting elements and spacers at the same time. In the preferred embodiment, all three elements: core container, connecting elements and contact surface consist of the same solid material.

to exact shape of vessel and contact surface: precise Shape of the core container: Come as an inner vessel shape all known, appropriate types of vessels and their execution in simple forms in which hot dishes are served, or from which hot food can be consumed. Examples: cup, espresso cup, Mug, jug, bowl, small bowl, Bowl, Plate, bottle, jug. Example of simple shape variants: bulbous, straight, high, low, wide, narrow; Contour cut: concave, convex, straight, wavy lines.

exact Shape of the contact surface: the Shape of the contact surface first determined in a circular manner by the shape of the core container. It repeats the shape of the inner vessel like a layer of cladding in an outer orbit, in the preferred embodiment plus a magnification factor, a distance of a few millimeters (see page 2) between both surfaces to generate the air space necessary for insulation leaves.

In With regard to the contour of the contact surface the position on the core container an important role. It hangs depending on where and how to touch from an ergonomic point of view should be done. On one or more determined position (s) the previously described coat layer put on, it is in her Size limited and only circumscribes the area that rests on the size and shape body part oriented. This is usually an average sized palm, two Palms, two fingers, four fingers, six fingers or possibly also other body parts (e.g. with larger serving vessels).

In addition to the exact ergonomically determined shapes and sizes, the contact surface can be varied in terms of design: it should at least trace the contour of the body part lying on it ( 9 ), the exact form ( 3 ) does not have to show exact finger traces or the like, it is simplified and abstracted ( 7 ). For a better idea: in a preferred embodiment of a drinking cup, the contact surface looks like an oven glove placed around the core container. The abstracted design of this contact area thus gives freedom, the contour line can be varied, for example it can also be angular.

applications for one ergonomically sensible design:

• - A drinking cup should have a single circumferential contact surface which, viewed horizontally, covers about three quarters of the circumference of the cup. (One-hand grip, 3A )
• - One Drinking bowl should have two contact surfaces, to be kept safe.
• - At a larger serving bowl must be determined beforehand be where the touch areas most sensible. More than two contact surfaces could also be determined be if during a change of use seems reasonable.
• - One very small espresso cup may only be between two Fingers held. The touch area will then be in two small opposite surfaces trained, on each of which a finger rests securely.

On a special aspect is the expression as right- or left-handed vessel for vessel types with one hand. There is freedom of design here: the contact surface can become very thick the palm of your hand orient - then creates a special right-handed or left-handed vessel. To avoid this problem can also consciously a more abstract design of the contour of the contact surface can be selected, big enough in both directions to be gripped on both sides.

When designing the contact area, care must be taken that the double surface has a maximum of 90% of the wall of the core container ( 2 ) and that at least one sufficiently large area in the upper area remains single-walled up to the edge ( 4 ), where ergonomic sensible use rest your lips

The preferred area of application is that for hot drinks (coffee and tea) and for soups. Another possible one The scope is for heavily chilled beverages and food. The preferred embodiment is one solid, durable and high quality material (e.g. porcelain), because it slows down the wear and tear process and the vessel becomes one long usable item is qualified. In this respect, primarily with Production the quality, and not the cost factor. The second preferred embodiment consists of a less solid single-use material. Further embodiments exist in other materials and material combinations.

The "vessel for hot beverages and food " many advantages of the known containers mentioned at the beginning and solves their weaknesses:

• 1. It is in the preferred embodiment - like that Vessels from a., b. and c. - on single-walled areas where the lips rest for drinking. By touching the lips to the vessel wall you can feel how hot that Content is. This minimizes the risk of burning your mouth. (This risk exists entirely trained double wall or insulating vessels, as under d., e. and f. ) Described.
• 2. The double wall in the contact areas makes this possible direct encirclement of the vessel with the Hands. This makes the vessel safe and held with minimal effort. This is a pleasant one Handling that does not have to be learned, a haptic experience, a natural and intuitive gripping behavior, and for certain people (children, Parkinson's sufferers, the weak ...) even a great help.
• 3. The heat is due to the two wall thicknesses and the one in between Air space in the touch areas insulated so far that you don't burn your fingers when you touch it. Just like in c., d., e. and f. Another advantage: the hands are with the incoming The remaining temperature is comfortably warmed and the shape indicates this effect.
• 4. The temperature of the hot drink or food will half isolated in such a vessel. The heat loss is stronger than in a completely double-walled container like d. or f., but less than in the single-walled vessel type a. or b. This is a useful one Effect, for example with completely double-walled cups must often wait too long until a good drinking temperature is reached is.
• 5. In the preferred embodiment The vessel can be made of hot solid material such as porcelain beverages and food is cleaned well, is stable and has the same everywhere Properties - as Advantage to c. and G.
• 6. For all types applies: By touching the areas are clearly visible and dispense with further holding devices (a handle, for example), the first-time user will immediately recognize where and how to handle the vessel is as Advantage to d., E. and f.
• 7. In the special embodiment from a less solid single use material the clear expression of the contact surfaces as special advantage because the operation is self-explanatory. On Disposable container must be light understandable his.
• 8. The non-existing handle enables space-saving, uncomplicated storage in a dishwasher and cupboard (a.), depending on the vessel type and formal design is also possible stacking.
• 9. With a construction as in 5 the vessel can be assembled from two different materials. This could be used for some sort of collection or deposit system, in that the exterior is made of a solid, durable material and is available for purchase, while the interior is made of non-rigid material, used only during use, and then discarded or recycled.
• 10. Overall, the innovation not only improves the technical and functional Aspects like non-burning and good, secure hold in the hand, but also satisfies aesthetic and sensual needs of holding, feeling the weight, of the finger warming and enjoyment.
• 11. The design of circumferential contact areas as raised areas around offers an inner vessel good design options, as far as color variants and decors are concerned.
• 12. Due to the partial double wall, the core container remains in visible in its shape. The optical effect is slimmer than f. (entirely double-walled vessels).

The Production in the preferred embodiment porcelain: the production in the porcelain material, at least two methods are possible:

• 1. In double-walled casting of the entire mold: This is possible with two to three negative molds (depending on the type of vessel). This creates an opening on the bottom of the vessel (which can be closed later using another material if necessary). The appearance of the laterally visible vessel is homogeneous - that is, there are no gaps or gaps ( 3A and 4 ). You can see the basic shape of the vessel, for example that of a cup, from its outer surface The area protrudes, which corresponds in size and shape to at least that of an overlying hand.
• 2. Production with attached contact surfaces: Two separate molds can be produced in the casting process - the inner vessel and the outer contact surface including spacers. The two are then combined in a further work step - for example by means of glaze during glaze firing. This type of production creates slits that can be seen from the side between the inner vessel and the contact surface ( 2 B ).

A another preferred application of the novelty is one less solid material for the Single use, for example in thin plastic, cardboard or edible Material. This can be in the area of packaging convenience products, about pourable hot soups. This can also be used as a take-away and single-use container (in the snack bar for soups and hot drinks in the bar). So far, very few double-walled ones have been used in this area Vessels for use, although there are several inventions in this direction (example: Utility model G 85 18 647.3 "Insulated Cups ").

The Manufacture of such a take-away container with the features according to Protection claim 1 is possible in at least two procedures:

• 1. 5 : A receptacle is made from a recyclable "disposable material" such as cardboard or thin plastic, with the special feature that an area-like area is raised in the wall, i.e. bulges outwards (for form, see page 3 "Exact shape of the contact surface" ). This vessel is then brought together with a second, simple inner vessel. The required air space and distance to the heat insulation is created between the inner vessel and the raised surface of the outer vessel, which acts as a contact surface. The stability is created by connecting the two vessels. The two vessels could be fixed by snapping them together using an upper bead ( 12 ) take place, or if necessary also loosely by laying around, nesting, clipping together, tacking, gluing or holding together.
• Second 6 : In a similar way, the grip area could also be made more material-saving by folding over a cuff which has the contact surface in places. In these special embodiments for single use, a double-walled design can also be selected in the contact area of the lips, as long as the outer and inner walls are so close together that no essential air space can form between them and that there is only a minimal insulation effect. The main air space for insulation is below the contact surface. In this embodiment, the outer vessel or the circumferential jacket region with the contact surfaces can also be made of a different material than the core container.

Furthermore are also for other possible Types of construction conceivable applications in material combinations, whose manufacturing processes then determine the exact shape. Important is the visible design of raised contact surfaces below the ergonomic aspects mentioned: In a special embodiment there is a vessel for hot Drinks and Food made from two or more different materials:

• a) there will be a contact surface made of a different material a core container attached. Example 1: a foamed Material in the area-like described Shape and size will on a solid core container glued. In this case, the airspace is created in the foamed material itself, no further spacers or gaps are necessary. Example 2: A metallic contact surface, the which includes spacers is made from a core container Porcelain attached.
• b) there is a contact surface with a core container connected from the same or different material. this happens by means of connecting elements made of a different material. Example: Between fixed contact area and solid core rubber-like spacers are glued.

Another special type of construction is characterized by the fact that the contact area is not double-walled, and yet the impression of a very similar vessel to that of the embodiment described at the beginning is created: By using many surface-mounted, attached bars or lamellas ( 11 ) a contact surface is visibly pronounced, which acts in the manner of cooling fins and creates the necessary distance for one hand to safely grasp and touch. The palm (or another ergonomically sensible part of the body) then lies on a field of closely spaced lamellae or rod ends. The other characteristics, such as the shape, the size, the visually sublime characteristics must be fulfilled - only the directly construction-related aspects of the double-walled main application can be disregarded.

It are beyond applications in a single material other than porcelain are also possible, for example a solid plastic.
