Definitions

  • the present invention refers to a multifunctional pressure regulation valve for a hollow body, in particular for a food container, which comprises a valve segment with a hole and a flexible device which covers said valve segment.
  • Food containers are common and versatile household articles which not only serve to store food, but are frequently also used as receptacles for heating food, e.g. in a micro-wave oven. Therefore, high quality food container have to fulfill various requirements. On the one hand, they have to be made from food approved materials which do not release any compounds which might contaminate the food, neither over long storage, nor when subjected to heat or radiation. A food container also has to withstand severe changes in temperature, e.g. from -18°C to 100°C, still retaining its shape and appearance even after long periods of use. Food container especially should remain airtight during storage to prevent air, humidity, molds or bacteria from getting in contact with the food. Therefore, in most cases there is a close fit between the lid of the container and the container itself.
  • US 5,989,608 A discloses a food container for cooking through use of a micro-wave oven.
  • This food container has a hole and a pressure regulation valve attached to the food container to close the hole.
  • This pressure regulation valve comprises a cover film, an adhesive layer applied over the surface of the cover film facing the food container and a separator film disposed between the adhesive layer and the food container, and having an area larger than that of the hole but smaller than that of the cover film.
  • valve material is constantly exposed to steam or spouts of hot water or other fluids when in use, it tends to deteriorate rather easily thereby losing its ability to operate properly. It, for example, does not close tightly once it has opened and, thus, has to be replaced after use. As a consequence, the use of said valve is limited to that of an overpressure valve.
  • US 5,988,592 discloses a valve for dispensing fluid food products.
  • This valve consists of an elastic member which contains a slit which is usually closed. In closed position the slit covers an outlet end of a product discharge tube. Pressing of the elastic member of the covering slit stretches the slit open and allows the fluid product to be dispensed.
  • the manufacture of this valve is rather complicated and expensive because of the many different parts of the valve which in addition consists of a hole range of different materials. Also, this valve can not be used as a pressure regulation valve.
  • valve system especially designed for microwave cookware can be found in a food container of HPLites communication GmbH, Montabaur, called MICRO Selection 180° (item number 534).
  • This valve is incorporated into the lid of the food container. It comprises a solid non-flexible disc to which several pins are attached, and which is embedded into the surface of the lid, which contains several openings. These pins are engaged in some of the openings of said surface of the lid. The remaining openings are also located beneath the non-flexible disc. The pins have a bulge at their respective ends which acts as a limit stop. Thus, overpressure can be released by pulling the disc away from the lid.
  • valve system once this valve system is opened it has to be closed manually to regain an airtight closure. Also, since the non-flexible disc is embedded in the surface of the lid, it is only difficult to open manually and can harm the user, especially when the container with the valve system has been kept in a refrigerator or a microwave oven prior to its opening.
  • a generic valve is also known from EP 0 794 127 A2.
  • This document discloses a dispensing package which comprises a self-sealing dispensing valve.
  • the valve comprises a valve head with a discharge opening formed by slits in the flexible valve head.
  • a predetermined discharge pressure is reached the valve head shifts outwardly due to resiliently flexible connective sleeves, and the slits in the flexible valve head open to dispense the fluid product.
  • each valve is only adapted to a single discharge pressure. Therefore, only minor deviations of the desired discharge pressure require a completely different valve device.
  • US 5,944,211 already discloses a pressure regulation valve for a hollow body which comprises a valve segment with an aperture and a flexible C-shaped top part which covers said hole.
  • the valve segment also comprises a wall in the form of a recess having slanted side walls which is circular in shape inside its peripheral zone.
  • the valve can be made from a thermoplastic elastomer (TPE) or a rubberised elastomer which is adapted to cover the valve segment and form interior and exterior sides of a valve head.
  • valve head has a convex orientation when the valve is closed and a less convex orientation when the valve is opened, that is, the valve system can be opened by pressing an interface thereby forcing the valve down and pushing its sealing ends up, away from the flat portion of the valve segment.
  • the distance within the boundaries of the circumferential slanted side walls allows the flexible device to be changed from a convex to a less convex orientation, and vice versa.
  • the valve segment and the C-shaped flexible top part can each comprise a shaft and a hole or recess as guiding means which correspond to each other and which act in combination to allow for a reproducible switch in the orientation of the flexible top part.
  • the valve according to the invention can be an integral part of a hollow body, lid or container, or it can be a separate device which can be affixed to an opening of the hollow body, lid or container, for example by glueing, clamping pressing or welding.
  • the valve according to the invention is an integral or separate part of the lid of a container.
  • the container itself may comprise at least one of these valves.
  • one pressure regulation valve positioned in the lid of a container suffices for dispensing fluids or for ventilation.
  • the valve according to the invention comprises a resiliently flexible curved device, hereinafter also called flexible device, which has an interior and an exterior side and which has a convex orientation when the valve is closed, and an underlying valve segment.
  • the valve segment can be part of the hollow body, the lid or the container or can belong to a separate valve system.
  • This valve segment comprises a peripheral zone on which the circumference or rim of the flexible device rests when the valve is closed, an inner part within the boundaries of the peripheral zone, and at least one hole in said inner part.
  • the flexible device covers the valve segment thereby covering as well the hole(s) in said valve segment.
  • the flexible device is curved, especially when it seals the hole(s) of the valve segment, then being in its convex orientation.
  • a curved flexible device lies above or below its central part.
  • a resiliently flexible device means that the curved device has a structural strength in itself which, for example, makes the device resisting a change in form or orientation just by its own weight. Therefore, additional external forces are usually necessary to change the form of the resiliently flexible device.
  • the flexible device can be made from plastic, especially from thermoplastic elastomers (TPE) or from metals, e.g. thin metal plates.
  • TPE thermoplastic elastomers
  • the flexible device may have any shape as long as it fulfills the above mentioned requirements, i.e.
  • the flexible device may have the shape of a square, rectangle, circle, ellipse, triangle, pentagon, hexagon or any other polygonal form.
  • the flexible device has a circular or elliptic shape.
  • An enhanced tight fit can also be achieved by providing the valve segment with a circumferential groove or groove-like structure, and the edge or rim of the flexible device on its interior side with a bulge or bulge-like structure which fits into the groove when the valve is closed.
  • the flexible device according to the invention operates as a valve head. In its closed convex orientation the interior side of the flexible device is not exposed to the atmosphere outside the container. Only when the valve is opened the interior side is visible from outside the container.
  • the flexible device is connected to the valve segment via one or more circumferential walls or via two or more separate walls.
  • the walls are either an integral part of the valve segment or additionally fixed to the valve segment, e.g. by glueing, welding or other well known fixing means.
  • the circumferential wall and/or the two or more separate walls are located within the peripheral zone of the valve segment. The distance between the boundaries of these walls allows the flexible device to be changed from convex to concave orientation.
  • the flexible device is linked to the top part of these walls, for example, with the aid of hinges or clips.
  • the interior side of the flexible device may also be welded or glued to these walls.
  • a circumferential wall In case a circumferential wall is used it has to be provided for at least one additional hole, either in this wall or in the valve segment or the central part of the flexible device lying in the boundaries of the wall, to allow for a pressure balance.
  • Separated walls are preferably aligned along a circular or elliptic line. They may be straight or bent.
  • the flexible device is connected to at least two of these walls in a manner as described above.
  • the distance between separate walls facing each other or the diameter of a circumferential wall has to be chosen in such a way that it is possible to press onto the central part of the flexible device, thereby allowing the flexible device to switch from convex to concave orientation. This distance mainly depends on the size of the flexible device and the material it is made from.
  • valve segment and/or the flexible device of the present invention might each comprise at least one guiding means which correspond to each other and which act in combination to allow for a reproducible switch between convex and concave orientation of the flexible device.
  • Suitable guiding means are described in more detail in the following.
  • the guiding means comprise pin or pin-like structures when the valve is closed.
  • the top of said walls does not touch the interior side of the flexible device when the valve is closed, but is in contact with the flexible device when the valve is opened.
  • the guiding means comprise pin or pin-like structures on the one side, and orifices, claws, claw-like structures, tubes or containers on the opposite side, which are complimentary to each other while engaged.
  • the guiding means of a flexible device comprises at least one pin or pin-like structure on its interior side
  • the guiding means of the valve segment comprises at least one orifice or at least one claw, claw-like structure, tube or container complimentary to said pin or pin-like structure which engage said pin or pin-like structure at least when the flexible device is moved towards the direction of its concave orientation.
  • the guiding means of the valve segment comprises at least one pin or pin-like structure
  • the guiding means of the flexible device comprises at least one orifice, or at least one claw, claw-like structure, tube or container on its interior side complimentary to said pin or pin-like structure which engage said pin or pin-like structure which engage said pin or pin-like structure at least when the flexible device is moved towards the direction of its concave orientation.
  • These guiding means are preferably located at a central part of the flexible device.
  • the pin or the tube or container is fixed to the interior side of the flexible device at a position which is furthest apart from the plane stretched out by the circumference of the flexible device when in convex orientation, and is directed towards the valve segment where the corresponding guiding means is positioned.
  • a limit stop preferably at its terminal part, e.g. in the form of a bulge or broadened pin-element.
  • an orifice is the corresponding guiding means its diameter has to be chosen in such a way that it is smaller than the bulge or broadened part of the terminal part of the pin so that the flexible device can not be completely detached from the valve element.
  • a container or tube into which a pin with said bulge or broadened terminal end is engaged can be supplied with walls which are tapered towards the opening or which are bent towards each other at the opening part thereby preventing the passage of the limit stop. The same applies when claw or claw-like elements are used as guiding means.
  • the length of the pin and/or the position of the limit stop are as such that the curved flexible device can not adopt its original convex curvature, but only a less convex shape thereby exerting a pre-stress on the flexible device when in closed position. In this way an even tighter fit is achieved between flexible device and the peripheral zone of the valve segment.
  • the pin or pin-like structure may have at least one holding notch, which usually can be of similar shape than the limit stop.
  • a holding notch should fix a flexible device in a predetermined position only temporarily, e.g. to adjust the amount of fluid to be dispensed, it can be a bit smaller in size than the limit stop.
  • the limit stop in a preferred embodiment, also the holding notch allows to exert a pre-stress on the flexible device when in closed position.
  • the degree of pre-stress on the flexible device can be varied, as long as the flexible device does not turn into flat or concave orientation, or as long as the interior side of the flexible device does not rest on the top of the walls of the valve segment. In this way, the pressure at which the overpressure shall be released can be easily adjusted.
  • a flexible device is not only fixed to the valve segment by guiding means, but is also connected to one or more circumferential walls or to two or more separate walls as described above.
  • the surface of the valve segment which comprises the hole(s) and the wall(s) may be in plane of the lid or the container.
  • this valve segment comprises within the boundaries of its peripheral zone a depressed or deepened area, most preferably in its center part, furnishing a greater distance between the bottom of the this area and the central part of the flexible device in its convex orientation.
  • the guiding means e.g. the claws, the claw-like elements, the container or the pin or the tube are attached to this deepened area.
  • the circumferential wall or the two or more separated walls can be placed on the rim of this deepened area.
  • the rim of the deepened area of the valve segment itself may lie above a plane stretched out by the peripheral zone of the valve segment, thereby substituting the before mentioned walls or being part of them.
  • a food container 1 according to a first embodiment of the present invention is illustrated which comprises a valve 3 positioned in a lid 5 of the food container 1.
  • the lid 5 covers the receptacle 7 of the food container 1.
