Description

One aspect of the invention relates to a food receptacle for a household refrigerator. The food container has a bowl for holding the food. The food receptacle also has a lid that is separate from the bowl and that can be placed on the bowl to close the bowl tightly. Furthermore, the food receptacle has a vacuum generating unit, with which a vacuum can be generated in the shell closed with the lid. Another aspect of the invention relates to a household refrigerator with at least one such food container.

Such a configuration of a food receptacle with a vacuum generating unit is for example from the DE 10 2014 219 999 A1 known.

In the configuration of the food receptacle in the prior art, when a negative pressure is generated in the container, the built-up negative pressure can be reduced at least over a period of time, since an afterflow of air into the food receptacle, in particular via the vacuum generating unit, can be done.

It is an object of the present invention to provide a food storage container and a household refrigeration device in which the generation of the negative pressure is reliably made possible and the negative pressure generated can be maintained relatively uniformly over a longer period of time.

This object is achieved by a food receptacle and a household refrigerator according to the independent claims.

One aspect of the invention relates to a food receptacle for a household refrigerator. The food container has a bowl for holding the food. The food receptacle also has a lid that is separate from the bowl and that can be placed on the bowl to close the bowl tightly. The food receptacle also has a negative pressure generating unit with which a negative pressure can be generated in the shell closed with the lid. The food receptacle has at least one post-flow stop element, in particular a non-return valve, which is separate from the vacuum generation unit and has a check valve to prevent air from flowing into the vacuum receptacle through the vacuum generation unit. With such a configuration, a negative pressure generated in the food receptacle can be maintained permanently and with a substantially constant pressure value. The individually set storage conditions in the container can therefore be maintained very precisely and for a long time for specific foods, which has a positive effect on the storage conditions and in particular also on the shelf life of the foods. In particular, an afterflow into the container via a specific flow path, namely via the vacuum generation unit itself, can thus be efficiently prevented, so that precisely this possible leakage path is avoided in an improved manner.

It is preferably provided that the post-flow stop element, in particular the check valve, is arranged at an outlet of the vacuum generating unit, in particular is arranged directly at the outlet. With this configuration, the check valve can be securely installed and arranged on a component that is also mechanically robust in this context, in particular on the housing of the vacuum generation unit itself.

It can be provided that the vacuum generation unit is connected to the cover or the shell by a hose and the post-flow stop element, in particular the check valve, is connected to one end of the hose. Especially when the vacuum generation unit is installed at a distance from the lid of the food receptacle in particular, the hose can thus create a connection between the position of the vacuum generation unit and the connection point for extracting air from the container. Since the check valve is also arranged on the end of the hose in this regard, it is therefore not necessary to connect two hose parts to the check valve then installed between the hose parts. In this way, interfaces that lead to further leaks in the area of the hose can also be avoided better. In addition, the flexibility and laying of the hose is improved on its own, since it is more or less a one-piece part, which only has to be connected with the ends on the one hand to the cover or the shell, and on the other hand to the check valve.

The food receptacle also has, in particular, a displacement device with which the lid and the dish can be displaced relative to one another in the depth direction of the food receptacle when the lid is placed on the dish.

The food receptacle preferably has a coupling device with which the lid and the tray for closing the food receptacle, when viewed relative to one another in the depth direction of the food receptacle, are pressed against one another automatically in the vertical direction of the food receptacle . Such a configuration enables the sealed, in particular gas-tight, closing of the food receptacle inside the container. In this connection, no external components are required in order to enable the corresponding pressing between the shell and the lid. In addition, the specific coupling device also creates an automatism with which, due to the relative movement between the cover and the bowl in one spatial direction, a movement between the cover and the bowl in a different spatial direction occurs automatically. This configuration of the food receptacle enables a very simple, yet highly functional principle to automatically position the lid on the bowl when there is a relative movement between the lid and the dish, which causes the food receptacle to close cause that the gas tightness of the food container is reached. In addition, such a configuration also enables permanent, tight closing. In particular, the negative pressure generated can then advantageously be maintained.

In an advantageous embodiment it is provided that the coupling device has at least one receiving groove, the receiving space of which is delimited by an inner side of a boundary wall of the receiving groove which is inclined with respect to the horizontal. The coupling device has at least one coupling web, which runs into the receiving groove during the relative movement and contacts the inside, so that with a further relative movement the coupling web runs along the inside and the cover and the tray are moved towards one another in the vertical direction. In particular, the pressing against one another between the shell and the lid is then achieved automatically. Such a specific, objective design of the coupling device with a receiving groove provides a very simple, yet mechanically stable and correspondingly resilient component, with which automatically the movement in the vertical direction when the relative movement between the cover and the shell in the depth direction is initiated relative to each other, namely moving towards each other and pressing against each other, is achieved.

It can be provided that the coupling device has at least one receiving groove which has a boundary wall delimiting a receiving space of the receiving groove. The coupling device has at least one coupling web, which has a web side that is oriented in relation to the horizontal in the depth direction and is inclined or inclined. During the relative movement between the cover and the tray, the coupling web runs into the receiving channel or the receiving volume of the receiving channel and the web side contacts an inside of the boundary wall, so that with a further relative movement between the lid and the tray in the depth direction, the web side runs along the inside and the lid and the tray are moved towards one another in the vertical direction, in particular then pressed against one another. The advantages mentioned above can also be achieved in this way.

With the above-mentioned two embodiments, which can each be implemented individually, but can also be present in combination in one exemplary embodiment, a simple, yet mechanically robust one can be used for pressing the lid and the tray together when the food receptacle is closed highly functional system can be provided.

It is central in the context that two separate regions of a receiving groove and a coupling web, which directly contact one another during the relative movement between the lid and the shell, are designed and arranged in their position relative to one another such that in the contacted state and another Relative movement in the depth direction by the relative movement of the coupling web and the receiving groove a change in position between the cover and the shell occurs in the height direction, in particular occurs until these two components are pressed against each other in a sealing manner.

For this purpose, it is provided that at least one area of the coupling web and / or at least one area of the receiving groove is not parallel to the other area that is in contact with it, but is oriented with a certain inclination to it. In particular, it is then also provided in the context that a contact point which occurs during the relative movement in the depth direction between the cover and the shell or which is already fundamentally present is between the coupling web and the receiving groove at a height which is not the same as the end position when the cover and the tray are positioned to each other so that they have the closed state. In particular, this is the coupling point, which is in an intermediate position during the relative movement between the cover and the Shell occurs in the depth direction, at different heights to that position when the lid and the shell have their closed end position, which is particularly the case when the relative movement in the depth direction between the lid and the shell is complete or in this respect an end position in the depth direction this relative movement is reached.

It can be provided that the area of the coupling web provided for contacting the receiving groove, in particular the inside of the boundary wall, is oriented horizontally or is inclined obliquely with respect to the horizontal. In addition or instead of this, it can be provided that an inside of the boundary wall of the receiving channel is inclined with respect to the horizontal or is also oriented horizontally.

In an advantageous embodiment, it is provided that the inner sides of the boundary wall of the receiving channel are arranged obliquely or inclined relative to the horizontal such that the receiving channel is widened from a channel bottom to a channel entrance. The inner sides of opposing boundary walls of the receiving channel are then designed in such a way that the receiving volume widens toward the channel entrance.

It is preferably provided that the coupling device has a rear first receiving channel, viewed in the depth direction of the food storage container, and at least one front second receiving channel, which is separate from this. With such a configuration, an improved sealing arrangement between the cover and the shell can then be achieved in the closed state. The relevant mechanical coupling between the shell and the cover is thus formed both at the front end and at the rear end, so that a specific pressing against one another is automatically generated both at the front and at the rear.

In particular, it is provided that the first receiving groove is arranged or formed on a rear edge of the lid and, when viewed in the depth direction of the food holding container, is open to the front. In particular, it is provided that the first receiving groove extends in the width direction of the food storage container over at least 50 percent, in particular at least 80 percent, of the width of the lid. Due to the specific orientation of the receiving channel with the channel opening towards the front, the coupling web can be inserted in a particularly safe and targeted manner when the lid is pulled forward from an open position in the depth direction in order to close the food receiving container.

By additionally or instead of forming the corresponding width of the receiving channel and thus designing a channel rail, the coupling can be carried out more extensively in this regard and can thus be improved so that mechanically stable coupling and firm pressing of the components is achieved over a corresponding width . This improves the sealing, in particular gas-tight, closed state between the shell and the lid.

It is preferably provided that the second receiving channel is arranged on a front edge of the bowl and, when viewed in the depth direction of the food holding container, is open to the rear. In particular, it can be provided that the second receiving groove extends in the width direction of the food storage container over a maximum of 10 percent, in particular a maximum of 5 percent of the width of the lid. When viewed in the width direction, this second receiving groove is preferably formed on a lateral end region of the shell. It is preferably provided that two second separate receiving grooves are formed on the shell. In particular, these two receptacles are designed with the above-mentioned advantageous orientations and / or dimensions in the width direction.

In an advantageous embodiment, it is provided that these two receptacles, viewed in the width direction of the food receptacle, are each arranged on opposite edge regions or side regions and thus on the end at the bowl. This design on the front with correspondingly positioned and in particular dimensioned second receptacles enables space-saving installation, so that the basic accessibility to a front of the cover is not restricted. As a result, the grip and actuation of the cover can be carried out by a user without restriction and there is no second receiving channel designed in this respect over a large width. In particular, this makes it possible to implement a space-saving configuration which nevertheless allows for sealing, in particular automatic pressing against one another in the vertical direction between the bowl and the lid, even in the front area of the food receptacle. The pressure on the front is thus locally via the second receiving channel formed on opposite corner areas. These are formed in one piece, in particular in the shell.

In particular, a grip strip is formed in a front area, in particular in a front edge of the cover. The grip bar is preferably oriented upwards. On the one hand, the lid is stabilized and has a higher torsional stiffness. On the other hand, actuation of the cover for relative displacement in the depth direction is made possible in a user-friendly manner. It can be provided that this grip strip, viewed in the width direction, is not formed up to the opposite edge sides of the cover, but ends set back. As a result, a thin plate-like or strip-like area is created on the opposite edge sides of the cover in the front area, which then serves as a respective coupling web or coupling web area in order to be able to run into the at least one second receiving groove. If the cover is thus pulled relatively forwards in the depth direction, starting from its open state, in which it is positioned offset to the rear relative to the shell, in order to achieve a closure, then these front coupling webs in the front area of the cover also run into the rear open, preferably two, receptacles and thus also in the front area there is a pressing in the vertical direction between the lid and the shell.

In particular, the advantageously available grip strip, as mentioned above, can also be used to implement a width dimension such that the cover is advantageously secured in position in relation to the shell in the width direction.

It is preferably provided that a first coupling web is an edge flange standing back in the depth direction and / or a second coupling web is an edge flange standing forward in the depth direction. An edge flange is understood to be, in particular, a circumferential collar of this type, which is arranged in an upper region of the shell, in particular this edge flange is thus a strip or plate region enclosing the upper edge region of the shell.

This configuration on the one hand stabilizes the shell in the upper region, and on the other hand enables a particularly simple and reliable mechanical coupling with the cover, in particular of the at least one receiving channel.

It is preferably provided that the shell has guide rails in which the cover is guided so as to be displaceable in the depth direction. This enables a straight, jerk-free and smooth movement of the lid relative to the bowl.

It is preferably provided that the cover has rollers which engage and are guided in these guide rails. This enables a further improved, smooth and jerk-free movement of the lid relative to the bowl.

In this regard, in particular, rollers are arranged in the front region of the cover on opposite edge sides when viewed in the width direction.

It is preferably provided that a sealing element is arranged between the cover and the shell, which is pressed against the top of an edge flange of the shell when the height changes between the cover and the shell. This is a further very advantageous embodiment, since the sealing element, as it were, coming from above, is placed on an upper side of the edge flange and is pressed there. In addition to the contact pressure or contact pressure generated by the coupling device, the weight of the cover also acts on the sealing element in this connection, so that in this regard an additional contact force is generated by this weight.

In an advantageous embodiment, the sealing element is T-shaped in cross section. As a result, a mechanically stable coupling possibility with a receptacle, in particular the cover, is achieved on the one hand by the T-stem, so that a secure position fixing of the sealing element on the cover is made possible. On the other hand, the T-roof creates an actual sealing element contact area which is of a flat construction, but which is then formed over a relatively large area, so that a large-area contact with the shell, in particular against an upper side of the edge flange of the shell, is made possible. This enables particularly reliable sealing. In particular, this configuration then also enables the sealing element on the one hand and the coupling device between the receiving groove and the coupling web on the one hand, to be positioned locally and very close to one another. In particular when the edge flange has the coupling web or is the coupling web. The contact forces generated by the coupling device thus act in the immediate vicinity and in a particularly advantageous manner directly on the sealing element.

It is preferably provided that the cover is designed like a hood or is designed like a trough and has a hood flange on which a sealing element and / or a receiving groove of the coupling device is formed. As a result, a very specific geometric shape of the lid is formed, which is the holding volume of the food holding container enlarged and an uplifted area of the lid is generated by the inverted tub shape. A partial volume of the food receptacle is thus quasi again formed in the lid itself. On the other hand, the local displacement of the receiving groove in the hood flange of this specific geometry of the lid does not affect the receiving volume of the container or these coupling elements do not then protrude into the receiving space.

It is preferably provided that the food receptacle has a coupling rail for coupling to a rail pull-out device. As a result, a physical unit is integrated into the food receptacle itself, which then enables it to be coupled directly to a rail pull-out device external to the container. The entire food receptacle and thus both the bowl with the lid as a whole can then be moved through the rail pull-out device, in particular linearly displaced.

The food receptacle preferably has profile parts in the upper region of the bowl on edge sides opposite in the width direction, which in particular have the advantageous guide rails already mentioned above and advantageously also have the coupling rails separate from the guide rails. Both the inwardly directed guide rails and the outwardly and / or downwardly oriented coupling rails are thus advantageously formed in these profiles. These profiles can be formed in one piece with the shell, but can also be separate components which are arranged on the shell so as to be non-destructive.

A one-piece design of the shell with these elongated profiles oriented in the depth direction is also possible.

The shell is preferably formed in one piece from plastic. It can be provided that the cover is made in one piece from plastic.

A rail pull-out device can be, for example, a telescopic rail, which thus has at least one fixed rail and one running rail.

A rail pull-out device can, for example, be arranged on the inside of an inner container of a household refrigeration device and the food receptacle can then be arranged on it in a manner that can be pulled out in the depth direction.

In an advantageous embodiment it is provided that the food receptacle has a vacuum generating unit with which a vacuum can be generated in the shell closed with the lid. The vacuum generation unit can in particular be a pump. It can be simply constructed and work, for example, on the principle of an air pump. In this connection, the pump has in particular a guide tube in which a pump piston is slidably mounted.

It is preferably provided that the food receptacle has at least one non-return valve to prevent air from flowing into the food receptacle through which vacuum is applied via the vacuum generation unit. This is a further very advantageous embodiment, on the one hand to enable specific storage conditions for specific foods in the container by generating the vacuum, and on the other hand to enable this vacuum to be maintained permanently and safely.

Another aspect of the invention relates to a household refrigeration device with at least one food receptacle according to the above-mentioned aspect or an advantageous embodiment thereof. Such a food storage container can be a fresh food container in which individual storage conditions, such as in particular an individual temperature and / or an individual air humidity and / or an individual pressure, can be set. This can then take place in particular independently of a remaining volume of a receiving space for food of the household refrigeration device. The food receptacle is in particular dimensioned such that it can also be carried as a separate unit and can therefore be removed and used from the receptacle. A certain degree of mobility can also be achieved in this way and the cleanability of the individual components can also be improved. The ability to be equipped is also improved. In particular, when a food storage container is arranged on rail pull-out devices of the household refrigeration device, an individual displacement can take place, in particular in the depth direction of the household refrigeration device, with the food storage container as a whole being able to be displaced accordingly.

With the information "top", "bottom", "front", "back," horizontal "," vertical "," depth direction "," width direction "," height direction "are the given positions and when the device is used and arranged as intended Orientations given.

Over the lid 9 can, as shown, an additional, separate cover 11 for example in the form of a partition, for example a glass shelf. The food storage container is a food storage container 8th represents.

The inner container 3rd has, among other things, two opposite vertical side walls 3a and 3b on.

At least through the cover 11 is the food container 8th of the remaining partial volume of the recording space 4th separated. The food container 8th is designed to hold food and has an exclusively mechanical vacuum generation unit 12th on how it is explained below using specific exemplary embodiments. By means of the vacuum generation unit 12th is a relative to the environment outside the food container 8th and thus for example, the recording room 4th reduced air pressure adjustable. The vacuum generation unit 12th For this purpose comprises an actuating element which is relative to the food receptacle 8th is movable and, depending on the movement of the actuating element, air from the food receptacle 8th and thus from the volume that passes through the bowl 10th and the lid 9 is limited, is extractable.

The food container 8th can be released non-destructively from the recording room 4th be removed. Even when inserted in the recording room 4th it is intended that the shell 10th in the depth direction and thus in the z direction in the recording space 4th stored condition can be pushed back and forth to the inside of the shell 10th to be able to get there.

In 2nd is a perspective view of an embodiment of a food container 8th shown. The food container 8th is shown here in the closed state. This is the lid 9 , which is plate-like, closes from above on the shell 10th arranged. In particular, gas-tight sealing is formed here.

The food container 8th has a displacement device 13 with which the lid 9 and the bowl 10th when the lid is in place 9 on the bowl 10th in the depth direction (z direction) of the food receptacle 8th are displaceable relative to each other. A linear shift in the depth direction is made possible here. In this context, the exemplary embodiment provides that the food receptacle 8th Profiles 14 and 15 having elongated profiles and extending in the depth direction. They are in the width direction (x direction) of the food receptacle 8th on opposite sides of the bowl 10th arranged. They can be integral with the shell 10th be trained. The profiles 14 and 15 However, they can also be separate components in the upper area of the shell 10th are arranged thereon, in particular are arranged thereon in a detachable, non-destructive manner. As can be seen in the context, the profiles show 14 and 15 Guide rails 16 and 17th that are open on the inside and thus on the sides facing each other. In these guide rails 16 and 17th , which can also be referred to as a guide backdrop, grip guide elements, which here are in the form of roles, for example 18th are trained, a. In 2nd is just one role 18th to recognize the edge on the lid 9 is arranged. On the opposite side in the width direction is a corresponding further role 18th arranged.

The roles 18th are in a front area of the lid 9 rotatably mounted or arranged thereon.

The lid 9 has a handle bar in its front area, especially as a front end 19th on. This is viewed in the vertical direction from the top of the lid 9 standing up. The handle bar 19th has a raised grip area in the middle 20th on. Viewed in the width direction, the handle bar extends 19th especially uninterrupted. However, it does not extend to the outer side edges 21 and 22 ( 3rd ) of the lid 9 . Rather, the handle bar ends 19th compared to these margins or margins 21 and 22 set back inside.

The food container 8th also has a coupling rail 23 and 24th through which a coupling with a to the food container 8th separate rail pull-out device is enabled. This rail pull-out device can be a telescopic rail. It can be on the inside of a vertical side wall 3a and 3b be arranged so that the food receptacle 8th viewed as a whole in the depth direction from the recording room 4th can be pulled out and pushed in.

The coupling rail 23 , 24th can in a profile 14 , 15 be trained, in particular be integrated.

In addition or instead of this, it can also be provided that on a side wall 25th the Bowl 10th spaced apart from a profile 14 , 15 a coupling rail 26 for coupling with such a rail pull-out device is available. Different variants of a food receptacle can thus be used 8th be provided with regard to the coupling with a rail pull-out device. The exemplary embodiments mentioned can each be designed individually, but can also be present in a common example, so that redundant coupling structures for coupling with a rail pull-out device are created here.

In addition, in 2nd realizing that the food container 8th a coupling device 27 with which the lid 9 and the switch 10th for closing the food container 8th with a relative movement in the depth direction to each other automatically in the height direction (y direction) of the food receptacle 8th be pressed together.

This coupling device 27 has, as in a perspective vertical sectional view along the section line IV-IV in 2nd in the drawing file in 4th a first receiving channel can be seen 28 on. This first receiving channel 28 is in a back area 29 of the lid 9 formed, in particular in one piece with the lid 9 educated. In particular, the lid 9 dome-shaped, like this in 4th can be seen. The hood-like lid 9 in this context has a hood flange, in particular at least in some areas, in particular completely, encircling 30th on which this receiving channel 28 is preferably integrally formed. In particular, the lid 9 formed in one piece, preferably made of plastic.

The receiving channel 28 extends in the width direction by at least 50 percent, in particular at least 80 percent, of the width of the cover 9 . The receiving channel 28 is through an upper boundary wall 31 and a lower boundary wall 32 limited. A gutter opening 33 is oriented towards the front when viewed in the depth direction, so that the receiving channel 28 is open towards the front. As in the illustration in 4th can be seen, a recording volume expands 34 the receiving channel 28 towards the front and thus towards the channel opening 33 on. In the exemplary embodiment it is provided that an inside 35 the lower boundary wall 32 is arranged obliquely or inclined to a horizontal that extends in the xz plane. In particular, this is inside 35 inclined forward and downward in relation to this horizontal in the depth direction.

The coupling device 27 also has a coupling web 36 on, in particular on a back wall 37 the Bowl 10th is integrally formed. This paddock 36 forms in the embodiment in particular an upper edge flange of the shell 10th . The paddock 36 extends in particular horizontally in the depth direction to the rear. As in the illustration in 4th there is an underside 38 this coupling web 36 on the inside 35 the lower boundary wall 32 at. The paddock 36 dives in this closed position of the lid 9 in the first receiving channel 28 a.

As can also be seen, there is a sealing element 39 on the lid 9 arranged, in particular on the hood flange 30th arranged. This sealing element is in cross section 39 here in particular T-shaped. A T-stem is in a channel-shaped or groove-like receptacle in the hood flange 30th arranged so that the sealing element 39 is held in it. AT roof of this sealing element 39 lies on a top 40 of the coupling web 36 , which also represents an edge flange here. As thus in the representation in 4th can be seen, are the first receiving channel 28 and the sealing element 39 arranged locally adjacent to one another, in particular in the hood flange 30th . As a result, the coupling between the first receiving channel 28 and the coupling web 36 created a mechanically stable connection and an approaching height between the shell 10th and the lid 9 achieved and additionally by the locally immediately adjacent attachment of the sealing element 39 then a particularly tight, in particular gas-tight, closing connection between the cover 9 and the bowl 10th reached. This sealing element 39 is from the top of this top 40 pressed on and pressed against it.

This is done by moving the lid 9 starting from an unlocked position, for example an open position, as shown in 3rd the food container is shown 8th is closed. For this purpose, in the exemplary embodiment according to the representation in 3rd the lid 9 pulled forward in the depth direction and thus correspondingly linear relative to the shell 10th emotional. The coupling web then contacts on this movement path 36 , especially the bottom 38 , the first receiving channel 28 , especially with a front area the inside 35 the lower boundary wall 32 . The height between the shell is on this path of movement 10th and the lid 9 predefined so that this coupling web 36 the inside 35 relatively far forward at the channel opening 33 contacted. When the cover moves further 9 then the bottom becomes in the depth direction 38 along the inside 35 moved and due to the inclination at least the inside 35 then becomes the coupling web 36 to the lid 9 moved there. A relative movement between the cover considered in the vertical direction thus takes place automatically 9 and the bowl 10th , in the context of which there is a movement towards one another. This continues until the in 2nd shown closed end position of the lid 9 is reached and then the lid 9 and the bowl 10th are pressed against each other and then the sealing element in the context 39 to the top 40 is pressed. This pressed together state is then by the specific coupling device 27 also kept.

In 5 is a section of the food container 8th shown in the front area. Here too is the sealing element 39 on the top 40 of the front section of the coupling web here 36 shown sitting and pressed on.

In 6 is a perspective view of the rear portion of the lid 9 shown. The first receiving channel 28 can be seen better again.

In 7 is a perspective view of a portion of the food container 8th in the closed state according to 2nd shown. There is a second receiving channel here 41 shown, which is formed on the front. This second receiving channel 41 is formed on one end side when viewed in the width direction. She is here in the profile 14 integrated. This second receiving channel 41 has a recording room 42 which, when viewed in the depth direction, is open to the rear. This recording room is also here 42 to a gutter entrance 43 trained expanded. The second receiving channel 41 is through a lower boundary wall 44 and an upper boundary wall 45 limited. The upper boundary wall 45 has an inside 46 on, which is inclined or inclined to a horizontal. The slant here rises upwards and backwards in the direction of the channel entrance 43 considered trained. As in 7 It can be seen that there is an edge-side coupling area as a coupling web 47 of the lid 9 into this in the shell 10th integrally formed, second receiving channel 41 arranged immersed. Here's a top 48 this coupling web 47 with the inside 46 in contact. This will cause the inside to be inclined 46 the lid 9 also in the front area during the relative movement in the depth direction of the lid 9 relative to the shell 10th pressed down. The top 48 contacted when closing the lid 9 in a certain intermediate position when closing the inside 46 in a front area. When the cover is moved relatively 9 this top runs in the depth direction 48 along this inside 46 and is due to the inclination of this inside 46 down to the bowl 10th pressed down and onto the boundary wall 44 that here through the front section of the coupling web 36 is formed on the top 40 pressed. This second receiving channel extends in the width direction 41 preferably a maximum of 10 percent, in particular a maximum of 5 percent across the width of the food receptacle 8th . In particular, this second receiving channel extends 41 across the width of the profile 14 . A corresponding second receiving channel 41 is on the opposite side, especially in the further profile 15 , trained, especially integrated. The design and functionality there is corresponding to how it relates to the second receiving channel 41 was explained.

As in 7 can also be seen, the handle bar ends 19th viewed in the width direction in front of the coupling area and thus this coupling web 47 so that the handle bar 19th during the coupling or when the coupling web enters 47 in the second receiving channel 41 is not in the way.

In an alternative embodiment it can also be provided that according to the illustration in 4th not the inside 35 is inclined to the horizontal, but the bottom 38 is inclined accordingly. In a further alternative embodiment it can be provided that both the inside 35 as well as the bottom 38 is inclined to the horizontal.

In addition or instead of this, it can also be provided that the inside 46 is not inclined to the horizontal and then a corresponding inclination of the top 48 is formed. Here, too, it can alternatively be provided that both the inside 46 as well as the top 48 are inclined accordingly.

It is essential in all versions that when closing the lid 9 before the final closed position contacting areas of the lid 9 and the bowl 10th are designed so that with a further relative movement of the lid 9 to the bowl 10th then in the depth direction these coupled areas on the further path of movement considered in the height direction to move towards each other between the shell 10th and the lid 9 effect and in the closed position of the lid 9 the shell 10th and the lid 9 are pressed together.

In 8th is a perspective view of another embodiment of a food container 8th shown. The geometric design of the lid 9 and the bowl 10th are slightly different here. However, the functionality, in particular with regard to the relative movement in the depth direction and the movement towards one another automatically and resulting therefrom, is corresponding to how this is 2nd to 7 was explained.

In this embodiment, there is also a vacuum generating unit 49 provided that, however, also in the embodiments as they too 2nd to 7 have been explained, may be present. The vacuum generation unit 49 can the vacuum generating unit 12th be, and vice versa. In particular, it is provided here that the vacuum generation unit 49 , which in particular a pump, such as working on the basis of an air pump principle, immediately adjacent and to the shell 10th is arranged adjacent. It can be provided that the shell 10th a niche in the lower area 50 in which the vacuum generating unit 49 at least partially immersed. In this vacuum generation unit 49 can in the volume through the shell 10th and the lid 9 is limited, a negative pressure can be generated.

In 9 is in a vertical sectional view along the section line IX-IX in 8th the Food receptacle 8th shown. Here, too, is the individual design of the second receiving channel in the front area 41 that are integral with the shell 10th is trained to recognize. The first receiving channel is in the rear area 28 and the coupled state with the coupling web 36 shown.

In 10th is a perspective view of the food container 8th from another, compared to 8th shown perspective shown. It can be seen here that the vacuum generation unit 49 with a hose 51 with in particular the lid 9 is fluidly connected. It is also provided that the food container 8th a check valve 52 having. With this is an afterflow of air from the vacuum generating unit 49 into the volume of the food container 8th connected. The check valve 52 is here directly at the vacuum generation unit 49 arranged. On the other hand, this is a check valve 52 with the hose 51 connected via a connector 53 then here with the lid 9 connected is. The hose 51 is thus at one end with the check valve 52 and with the other end with the connector 53 connected.

In addition, rail pull-out devices are also examples here 54 and 55 shown on the shell 10th are arranged.

In 11 FIG. 10 is an exemplary illustration of a vacuum generation unit 49 shown. The check valve 52 , the hose 51 and the connector 53 are also shown.
