Description

Technical field

The invention relates to a container for storing food treated with a vacuum system by means of a vacuum suction valve located in the lid, which exhausts air from the container to increase the shelf life of the food, provided that the cooked food is heated in the microwave at the same time.

BACKGROUND OF THE INVENTION

Containers are known for storing raw and heat-treated foods treated with a vacuum system by means of a vacuum suction valve housed in a lid for exhausting air from the container. This will increase the shelf life of the stored food. Containers with such treated foods are usually stored in refrigerators or refrigerators at a temperature of about 5 ° C. The various types of food are usually kept in a separate container. Separate storage of different types of food requires several containers, which may then be missing for a different purpose. It is also time consuming and energy-consuming to heat individual types of food before consumption. This is because food is stored on one plate. If several people are preparing to eat, unheated meals are prepared on individual plates for microwave cooking. Because more than one plate may not be placed in the microwave, food cannot be served to everyone at the same time and is therefore served gradually. This is disadvantageous in view of the relatively long waiting time for all the plates to be heated and, secondly, to the significantly different temperature of the food consumed at different time intervals.

Also known are containers in the form of plates, trays and dishes with separate compartments for various ingredients of raw or cooked food. It is for example a plate according to published application DE 41 23 364, provided with an outer flange and inner partitions which form one main space and three smaller spaces. The upper edges of the skirt and bulkheads lie in the same inclined plane. Separate compartments are used to accommodate meals depending on their volume, such as lettuce leaves. In smaller spaces, smaller-volume foods are placed, with liquid foods such as sauces and the like being separated by internal barriers from solid foods such as meat. The food tray according to French patent 9303694 is provided in one half with two enclosed spaces for placing foodstuffs. The other half is designed for placing knives, forks and glasses. Near the glass there is a through hole in the tray for inserting a thumb while carrying it. The dinner tray according to French patent 9704107 is provided with several shallow recesses for accommodating several kinds of food products, one of which can be provided with a lid. Said plate and trays are designed to carry two to three courses for one person from the place where they are prepared and delivered to the table where they are consumed. Also known are low bowls made of glass, often cut, in which compartments separated by partitions are placed various kinds of nuts, potato chips and the like. Their shape and design are at the same time aesthetic accessory for dining. Food placed in separate areas of the plates, trays and trays serves for immediate consumption, not for treatment with a vacuum system. Therefore, said dinnerware is not adapted to fit a lid with a suction valve. Given the overall configuration and shape of these containers, vacuum treatment in these containers is impossible. While several types of food can be stored in a single vessel designed for vacuum treatment, if several kinds of food, especially heat-treated foods of different states, are stored there, they become aesthetically agitated, both when stored in refrigerators and subsequently heated before consumption.

SUMMARY OF THE INVENTION

These drawbacks are largely overcome by a vacuum storage vessel treated by means of a valve in a removable lid, which drains air from the vessel to increase the shelf life of the food, assuming that the cooked foods in the microwave will be heated simultaneously before being consumed. SUMMARY OF THE INVENTION The container is provided with a partition for creating at least two separate internal spaces within the container for separately storing the various food ingredients. The fixed bulkhead is rigidly connected to the skirt and the bottom of the container. The removable partition is loosely inserted in the container. To create separate internal spaces within the container, the partition is provided with at least two arms. A cup-shaped recess is provided in the upper face of the bulkhead, in its central part, where the arms of the bulkhead join. An advantage of the arrangement according to the invention is that it allows placing, in particular, heat-treated foodstuffs in a single container in a larger quantity than the consumption of one person. After placing the foodstuffs in the separate compartments, the container is provided with a lid. Air is evacuated from the interior of the container in a known manner by means of a valve in the lid. With the food thus treated, the container is stored at a temperature of about 5 ° C, for example in a refrigerator or refrigerator. Before consuming the food, the lid is removed from the container and the container is placed in a microwave oven where all the food placed in the separate interior of the container is simultaneously heated to the consumable temperature. This makes it possible to prepare more than one course for more than one person at a time. It saves energy to heat food and time to prepare for consumption. The container can also be used to store various types of food that will not be heated before being consumed in the microwave.

Overview of the drawings

An embodiment of the invention is illustrated in more detail in the drawings, wherein FIG. 1 shows a circular container with a fixed two-arm partition, with two separate interior spaces and a lid in front view, FIG. 2 shows the same circular container with a fixed two-arm partition; Fig. 4 shows the same container in plan view, Fig. 5 a container of rectangular cross-section with rounded corners, with a four-armed rectangular partition and four separate interior spaces of the same volume in front view, Fig. 6 the same container 7 shows a container of rectangular cross-section with rounded corners, with a four-arm removable partition with arms extending in a diagonal direction.

DETAILED DESCRIPTION OF THE INVENTION

The vessel 1 is formed from a peripheral shell 2 which is closed at the bottom by a bottom 3. The circumferential shell 2 has a circular cross section (Figs. 1 to 4) or has a regular rectangular cross section with rounded corners (Figs. 7). The surfaces of the envelope 2 form an angle of 90 ° to the bottom surface 3. They can also form an angle slightly greater than 90 [deg.] With the bottom surface 3 so that the container 1 slightly widens upwards. The upper face of the cladding 2 is adapted to accommodate a known lid with a vacuum air vent valve from the interior of the vessel

The container 1 is made of a material in which heat-treated foodstuffs or foodstuffs in the raw state, such as glass or plastic material, are usually stored. Inside the container 1 is a fixed or removable partition 4. The fixed partition 4 is rigidly connected to the inner surface of the skirt 2 and the inner surface of the bottom 3 of the container 1. It is of the same material as the container 1 and or when pressing container 1 plastic. If the partition 4 is removable, it is loosely inserted in the container 1. It is also made of glass or plastic. The plane of the upper face of the partition 4 is below the bottom of a known shaped lid, which is provided in its central part with a known vacuum valve

-2GB 288469 B6 Exhaust. For this valve, a cup-shaped recess 5 is provided in the central part of the upper face of the partition 4. The number of separated interior spaces 7 depends on the number of arms 6 of the partition 4. The arm 6 is that part of the partition 4 which extends from the vertical axis of the partition 4 with the central vertical axis O of the container 1, to its circumferential envelope 2. Although the number of discrete interior spaces 7 is not generally limited, in practice, it generally does not exceed four discrete interior spaces 7.1 to 7.4. The partition 4 with two arms 6.1, 6.2, which forms an angle of 180 °, has the shape of a plate (FIGS. 1 and 2) and forms inside the container 1 two separate interior spaces 7.1 and 7.2 having the same volume. Bulkhead 4 with three equal arms 6.1. 6.2, 6.3 (FIGS. 3 and 4) form three separate interior spaces 7.1, 7.2 and 7.3 within the circular cross-sectional container 1. Angle relative to each other 6.1. 6.2. 6.3 the baffles 4 grip, it is the same, that is 120 °. In this case, all three separate interior spaces 7.1, 7.2 and 7.3 have the same volume. The individual arms 6.1, 6.2, 6.3 of the partition 4 may also form different angles with each other. Thereafter, the volume of the separate compartments 7.1, 7.2 and 7.3 will also be different. Four-arm partition 4 with equal lengths 6.1, 6.2. 6.3 and 6.4, forming an angle of 90 °, would form four separate interior spaces in vessel 1 of circular cross-section 7.1. 7.2, 7.3 and 7.4, which would have the same volume. This arrangement is not shown in the drawing. The four-armed partition 4, whose arms 6.1, 6.2, 6.3 and 6.4 form the same 90 ° angle (Fig. 5 and Fig. 6) and whose axes are parallel to the walls of the circumferential envelope of the rounded corners of the rectangular cross-section 7.1, 7.2, 7.3 and 7.4, whose volume is the same. If the arms 6.1. 6.2. 6.3 and 6.4 the four-arm baffles 4 in the container 1 with a rectangular cross-section with rounded corners extend diagonally to the opposite corners of container 1 (Fig. 7), forming four separate compartments 7.1, 7.2, 7.3 and 7.4 in container 1. The same shape as the first discrete interior space 7.1 has the opposite third discrete interior space 7.3. The fourth separate interior space 7.4 has the same shape as the second separate interior space 7.2. Different volumes of the separated compartments 7 can also be formed by partitions 4 with unequal long arms 6 which form a different angle or whose axis does not pass through the center of the vertical axis O of the container 1. The partition 4 or its arms 7 can also have a curved surface. Known removable inserts, not shown in the drawing, having the shape of an internal compartment 7 in which they will be used, can be used to separate some food ingredients, such as meat and juice.
