Patent number: 10934075Abstract: The present invention relates to a feeding device (1) for manual dispensing of a food product in fluid form packaged in a flexible container (3) and a method for this, which invention solves the problem of bulky and heavy feeding devices which leak food product. The feeding device comprises a dispensing tank (10) adapted to hold the container, an operating sleeve (30) arranged on top of the dispensing tank, and a piston (40) arranged inside the dispensing tank and adapted to compress the container when the operating sleeve by rotation axially displaces the piston along the inside of the dispensing tank in a discharging direction so that the container is compressed while dispensing the food product (2) and allows a return of the piston in a return direction opposite the discharging direction after each dispensing of food product.Type: GrantFiled: March 2, 2018Date of Patent: March 2, 2021Assignee: ASEPT INTERNATIONAL ABInventors: Stefan Cedergren, Daniel Cedergren

Publication number: 20160251125Abstract: The present invention relates to a dispensing valve (1) adapted to allow dispensing of a product (2), preferably a food product, for example a beverage, from a container (3) which is preferably closed and has the ability to collapse when product is dispensed therefrom. The dispensing valve has an elastic membrane (7) with one or more valves (1a), which is/are closed when the membrane (7) assumes an initial position (A), and is/are open when the membrane assumes a stretched position (B) to allow dispensing of the product out of the container. When the membrane assumes its initial position (A), the valve (1a) or valves have contact with at least one support member (15), which prevents the valve (1a) or valves from opening, whereby air is prevented from passing through the valve (1a) or valves to product (2) present in said valve or valves.Type: ApplicationFiled: October 24, 2014Publication date: September 1, 2016Inventors: Sten Drennow, Stefan Cedergren, Rickard Truedsson

Patent number: 8602267Abstract: The present invention relates to a device for discharge of liquid or substantially liquid products (2), preferably foodstuffs, e.g. mayonnaise, mustard, ketchup or dressing, from a compressible container (3) made of flexible material, preferably of plastic bag type. The container (3) is placed in an outer container (7) and is compressible by a compression device (4) in order to feed product (2) out therefrom through a nozzle (6). The invention is characterised in that a compression means (9) which forms part of the compression device (4) is disposed on a piston (17) adapted to being subjected to movements in a portioning direction (P3) so that the movable compression means (9) squeezes the container (3) in the outer container (7), and that the piston with its compression means (9) can perform a return movement in a return direction (P4) which is opposite to the portioning direction (P3).Type: GrantFiled: November 23, 2010Date of Patent: December 10, 2013Assignee: Asept International ABInventors: Sten Drennow, Stefan Cedergren

Patent number: 6837257Abstract: The present invention relates to a valve device at dispensers which are adapted for dispensing portions of liquid or semi-liquid products (2), preferably foodstuff, from containers, and which have vacuum pumps (5) for generating a negative pressure in passage systems (6) through which the products (2) are dispensed from the containers. The valve device is a magnetic valve device (9) which is designed as a permanent magnet device with a valve body (9d) which automatically shifts or changes position when the vacuum pump (5) has emptied a container (e.g. 3), such that said vacuum pump (5) immediately thereafter can empty another container (e.g. 4).Type: GrantFiled: July 3, 2002Date of Patent: January 4, 2005Assignee: Asept International ABInventor: Stefan Cedergren

Patent number: 6802436Abstract: The present invention relates to dispensing device for dispensing portions of liquid foodstuff from a foodstuff container. A pump device (5) includes a pump chamber (10) and a connecting pipe (7) or similar for connecting the foodstuff container (2) to the pump chamber (10) and a pump means (14) forming part of the pump device (5) is designed and can be affected such that said pump means (14) can generate a vacuum in the pump chamber (10), connecting pipe (7) and foodstuff container (2) for drawing foodstuff (4) out of said foodstuff container (2) to the pump chamber (10). At least portions (18) of a through-flow passage (13) for foodstuff (4) in the connecting pipe (7) taper in which the flow direction (S) in which food-stuff (4) flows through said through-flow passage (13). The connecting pipe (7) has an inlet pipe (11) which can be pressed through a flexible wall (3) of the foodstuff container (2) and be connected to a connecting member (21) therein.Type: GrantFiled: November 13, 2003Date of Patent: October 12, 2004Assignee: Asept International ABInventors: Sten Drennow, Stefan Cedergren

Patent number: 6554009Abstract: The present invention relates to a device at washing apparatus for washing objects, preferably spray guns, with a washing liquid, preferably a solvent. The washing apparatus (1, 2, 3 or 3A) has at least one wash chamber (5) in which the object (4) is located for washing and at least one first container (B1) for collecting impure washing liquid from the wash chamber (5). The washing apparatus (1, 2, 3 or 3A) further comprises a distilling device (8) for distillation of impure washing liquid and obtaining pure washing liquid. This distilling device (8) includes a third container (B3) in which impure washing liquid is vaporized. Means are provided to see to that the volume (V1) of impure washing liquid which at the most or as a maximum can be brought to flow from said first container (B1) to said third container (B3) is equal to or less than the volume (V3) for washing liquid in said third container (B3) in order to prevent said third container (B3) from located overfull (FIG. 1).Type: GrantFiled: November 27, 2000Date of Patent: April 29, 2003Assignee: Hedson Technologies ABInventors: Peter Beijbom, Niklas Johansson, Stefan Cedergren
