Patent Application
20210213634
The present invention relates to a multi-purpose holding device suitable for hygienic or clean holding of a product in a stable and firm manner, such product being for example food products of different types. The area of use may for example be slicing of the product into slices or bits or pieces, avoiding contact between the hand of the person holding the product and the product itself, or for handling hot products.
The present invention also relate to a method for use of such device.
Food product surfaces, such as bread, meat or other food products to be handled and/or cut into slices or bits, using sharp knives or other sharp cutting devices, are a source of spreading viruses and bacteria, due to the porous and organic surface, and since the food has to be firmly held by the hand when slicing.
In many instances when slicing bread, a number of persons may be in contact with the same bread when slicing, in particular as part of meals in hotels or the like. When slicing bread, one hand is used to firmly grip around the bread in order to hold the bread firmly against a supporting surface in a more or less stable manner, while the other hand is used to hold the knife for slicing.
This is not hygienic, since the hand holding of the bread may be infested or contaminated by viruses, bacteria or other detrimental substances or organisms. In addition, it is a risk of cutting a flesh wound in the fingers holding the bread.
In hotels, old people's home, kindergarten, schools, cantinas or hospitals, a cloth is commonly placed over and partly around the bread in order to prevent direct contact between the hand and the bread. The cloth is moved between different types of bread and may be turned upside down or drop down on the floor and taken up and used again. The same problem may occur in an ordinary household, where different persons of the household shall slice their bread. It may be adults, kids or juveniles with a cold, sneezing with dripping nose or dirty hands that may be in direct contact with the bread to be cut, or kids coming directly in after having played, slicing the bread without having washed their hand thoroughly enough. In such case, the bacteria are easily spread and transferred amongst the family.
When slicing meat, the meat is most often very hot and in addition, the surface may be greasy and slippery, requiring use of a fork in order to fix the meat stably against the supporting surface when slicing. Repeatedly use of a fork for fixation of the slippery or greasy meat to the supporting surface may often result in difficulties in obtaining equal slices and/or many penetrations in the upper meat surface caused by the teeth of the fork, resulting in uneven slices or disintegration of the piece of meat. Moreover, when handling greasy meat the fat tends to stick to the fingers and hand, requiring repeatedly need for cleaning and washing the hands before touching other objects.
WO 2007/085103 discloses a holder for use when slicing bread. The holder has a handle which is connected by means of a connecting part to a cover, to which a plurality of supporting legs are attached. To hold an object in position, the holder is held at the handle and put onto the object to be held.
U.S. Pat. No. 1,729,624 discloses a U-shaped slicing device comprising a yoke-shaped body to be mounted upon and partially encircling a product to be sliced, and means for guiding the blade of the knife over the surface of one end of the body in cutting a slice of the product. The slicing device is also provided with a handle, rigidly fixed to the device for gripping during slicing. According to this device, the hand holds a grip around a handle itself and is not in contact with the bread to be sliced, thus the bread is not sufficiently supported in a stable manner.
U.S. Pat. No. 5,287,784 discloses a bread slicing device designed specifically for use with cylindrical shaped loaves produced by home automatic bread baking machines. The device consists of two parts: a clear cover with built in knife holder and a bread slicing holder. The bread slicing holder is rigid, monolithic in construction, featuring two opposing parallel slicing guide side walls which extend vertically from the base of the unit along two lateral outside edges, facing upwards when slicing. The lower two-thirds of the side walls interior surfaces are concave forming with the concave bottom a tapered sharply textured cylindrical cavity. Bread is inserted into slicing holder by way of a wedged shaped entry chute. The chute momentarily compresses the bread as it is inserted into the top of the bread slicing holder. Bread loaf then expands, firmly securing it into the cylindrical cavity. The slicing guide side walls are divided by a series of evenly spaced parallel vertical slots. These slots guide the cutting implement permitting accurate and consistent slices to be produced.
It is therefore a need for a device that is hygienic, where the possibility of direct contact with a gripping and holding hand and the product to be held is eliminated, or at least substantially reduced, and also reducing the cutting risk for cuts or flesh wounds in the fingers or the holding hand.
The invention is based on the principle of using a thin, flexible or pliable sheet, that easily may adapt to or may partly be wrapped around the contour of the product to be held or handled and preferably also easily secure a firm grip around the product during handling. Moreover, the present invention is based on the principle of avoiding direct and/or contaminating contact between a person's hands and the food product to be handled, thus isolating the product from a direct hand touch and still achieving a firm grip around the product to be held.
It is a main object of the present invention to provide a multi-purpose holding device that for example may be used for slicing bread, baguettes, meat, roast beef and the like, requiring slicing into for example thin, evenly cut slices; for handling hot food, and in particular, but not exclusively hot meat or hot objects such as for example baking tray; or for handling hot objects such as bred or steaks, taken directly out from the oven, or for handling hot objects such as frying pan or baking tray.
It is an object of the present invention to provide a product for handling food where the possibility of contaminating or spreading bacteria or viruses from a person's hands to the product is eliminated or at least substantially reduces.
It is another object of the invention to eliminate or at least substantially reduce the risk for causing injury or cuts when slicing a product with a sharp cutting device.
Yet another object of the invention is to provide a multi-purpose device for holding and carrying object, such as hot products or products prone to being contaminated by bacteria and viruses.
A further object of the invention is to provide a flexible and pliable holder configured to easily adapt to the form of the object to be held and where the hand of the holder easily may hold around the object, all in accordance with the physiological build-up of a hand, easing the handgrip around the object to be held.
Another object of the present invention is to provide a device where the objects to be sliced are visible through the device.
Another object of the invention is to provide a hand held device provided with a certain degree of form stability, providing a certain inherent resistance against easily changed shape.
A still further object of the invention is to provide a device for holding products, ensuring a form and non-slippery holding effect,

Further, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Since the device 1 at least along parts, is pliable and flexible, then the device may more easily or readily take the shape of the object to be held.
The material used may be of a suitable plastic material, for example containing an anti-septic material, such as for example silver, providing both an inner and outer hygienic surface, not contaminating the object, goods, or product to be held and not transferring bacteria or viruses to the next user holding or using the device 1.
The device 1 comprises a main elongated body, preferably of a plastic material and with a preferably uniform U-shaped cross sectional shape in longitudinal direction, suitable for being extruded. The body comprising two legs 3 spaced apart where one end of the legs 3 are connected to an intermediate part, the three parts forming a monolithic or unitary body. The interconnection between the one end of each leg 3 and the intermediate part may be curved or arced transition 7. It should be appreciated that the free end of each of the two legs 3 of the U-shaped body may be provided with an outwards projecting and upwards projecting flipped ends 5, the transition 6 between the legs 3 and the upwards extending flips 5 being curved or arced. The purpose of this arced part to the enhance support against the supporting surface and to eliminate, or at substantially reduce the possibility of human contact with the supporting surface or the hand-held object, inside the U-shaped device 1.
Since the device 1 is flexible and pliable, shaped as an elongate U- or V-shaped profile 1, both the two legs 3 of the U-profile 1 may be pressed in towards the object to be held by the holding hand, such as for example a bread or a piece of meat (not shown), until a firm grip around the object is obtained, with the hand placed through the opening 4 of the handle 2 and with a hand grip on both sides of the U-shaped profile 1.
The embodiment disclosed is based on use of a more or less U-shaped profile 1, where the closed, intermediate part of the U-shaped profile 1 may have a more or less flat part in the area for the attached handle 2, or a curved transition part 7, while the legs 3 may for example project straight or slightly angled in downwards and outwards direction from the closed end part of the U-shaped profile.
According to one alternative a part of the closed part of the U-shaped profile 1, and/or a part of the outwardly extending legs 3 may be less flexible than the transition parts between the closed end and the stiffer leg parts.
According to one embodiment the present invention may be formed by a suitable material, dimensioned and configured to obtain the hand gripping effects for firmly holding an object. Such material may for example be anti-bacterial silicon rubber and the shape of the device may also have any other suitable shape than a U-profile in longitudinal direction, as long as the intended purposes are fulfilled.
As shown in
The handle may be aligned with the main longitudinal direction of the holder or form an angle with said longitudinal direction.
By providing the device 1 with one or more handles 2, enabling a hand to be introduced I between the handle 2 and the device 1, makes the device 1 easy to be lifted and moved from one object to another. With a hand introduced under the handle with fingers on both side of the profile 1, provides the required clamping forces on the object to be lifted and/or sliced, thus securing a sufficient fixture of the object and also a sufficient pressure against the supporting surface.
If the device 1 according to the invention generally is made of a more stiff, rigid and less pliable or flexible material, the transition part between the closed part of the device 1 and the legs 3 may be provided with a hinged transition made of a more flexible and pliable material and/or provided with one or more thinner section extending in longitudinal direction in the transition zone. In such case the bending effect may mainly be obtain by bending in the curved upper, transition part 7 of the holder.
If the material chosen for the device is a non-elastic or pliable material, the device may be provided with one or more section allowing bending and compressing or squeezing the device around the object, said section preferably being in the transition zone between the legs and the transverse part, interconnecting one end of each leg. Such hinged part may be made of a softer or more bendable material, or may comprise one or more parallel lines in longitudinal direction of the device with less thickness, forming a bending line. Such art may be co-extruded I with the remaining part of the device during manufacturing.
When moving the device to a new product to be held, the clamping force introduces by the hand holding the device is eased, relieving the compressive force on the object. This allows for a reduced pressure exerted on to the product. In such case the holding hand can be lifted off, moving the device to another object to be sliced.
The U-shape of the device secures that the inner surface of the device, if and when dropped to the floor, will not be in contaminated contact with the floor.
By using two different polymers, one type for obtaining the required flexibility in parts of the device intended to be more flexible and one for obtaining a stiffer and more rigid handle region of the device, i.e. by for example co-extrusion, a multi-purpose holding device to be placed around the product to be firmly held enabling in addition a firm grip, is provided. Consequently a firm grip around the product to be held may be obtained by allowing the fingers to press firmly the device against the product to be held, the palm of the hand pressing firmly the device and the food to be sliced down onto the supporting surface, stably and firmly fixing the food against the supporting surface.
The stiffer and more rigid part of the device 1 may be formed of a more transparent polymer, enabling the person to observe the product to be sliced. The polymers used may include particles of an anti-septic character, such as for example small and minute silver particles, ref. https://www.plastnet.se/article/view/520130/ciba_satsar_pa_bakteriedodande_plast, The purpose of this feature is to prevent spreading bacteria due to use of the device itself.
The handle 2 may be formed of a plastic or wooden material, where both ends may be provided with a guiding device, serving as a guiding surface for the knife. The handle may be glued or bolted to the rigid part of the device. The surface of the device may also have printed the trademark or other decorations or text.
According to another embodiment of the invention, the central handle may be offset to one side of a longitudinal plane of symmetry extending lengthwise through the holder. In addition or instead, the central handle and its opening may be arranged in a skewed position in respect to the longitudinal axis or longitudinal plane of symmetry of the device.
The holding device may be provided with stiffening ribs extending in an orthogonal direction with respect to the longitudinal direction of device and the object to be held.
In addition to possible non-slippery surface arranged on the side of the holder facing the product to be held, the surface against which the holders hand is resting may also be provided with a contour or texture that avoid unintentional slippery of the hand, even with a greasy hand or surface.
