Butter dishes or similar containers for food

The invention relates to a container that has both for the storage as well as for serving of food, .like Butter or the like, is suitable. The container is easy to open and close, is easy to clean, granted, a moisture- and odor-tight seal of the contents and enables its rapid and continuous cooling.

The invention is based in particular on the object of designing such a container so that its contents in. kept a substantial distance from its sealing surface although an area can also be provided for serving utensils or dispensing equipment, as well cleaned without touching the sealing surfaces can.

For this purpose, a lower part is marked with Side walls and box-like lid of existing container according to the invention, characterized in that on the side wall of the lower part one outward facing bar and one likewise

integrally formed with the side wall, but at a considerable distance from this, 'downwardly extending sealing wall connects, which ends in an upwardly bent flange, and that the side walls of the lid a sealing with the Sealing wall can be brought into contact contact zone ', by an adjacent provided, outwardly Peripheral flange is stiffened.

A container according to the invention therefore offers significant advantages over known containers of this type, in particular in terms of reliable sealing, even after frequent use. This is primarily due to the in-depth Inner surface of the bottom part and the bar surrounding it, which clearly defines the sealing surface Keeps distance from the content.

An embodiment of the invention is described in more detail below with reference to the drawing, namely show:

Fig. 1 in an exploded view as an embodiment the invention a butter dish or the like;

2 shows a side view of the same container consisting of a base and a lid; and

3 shows a section along line 3-3 in FIG. 2.

The container consists essentially of a lower part 8 and a lid part 21. The lower part has a substantially flat, recessed, grained inner surface and one with it one-piece, upwardly directed side wall 12, which is in an outwardly directed strip, a downwardly directed wall part and an outward and upward bent flange over-

009840/1263

goes. The lid 21 is an open, box-shaped part with a bottom and continuously adjoining it, downwardly directed side wall. Runs near the bottom edge an outwardly directed peripheral flange. The lid fits tightly over the lower part, as the contact zone is conical and thus tightly closed between the two parts.

In detail, the illustrated embodiment shows the lower part 8 with a substantially flat, recessed Inner surface 10, the surface of which is textured or grained, injiem arbitrarily oriented, small hemispherical projections are provided on the surface, as indicated in FIGS. 1 and 3. The inner surface 10 is integral with an upwardly directed one Side wall 12 is formed, the upper edge of which is fixed to an outwardly directed, circumferential strip 14 is connected or formed in one piece with this. The bar 14 is in turn integral with one of her carried downwardly directed sealing surface 16, which is formed in an upwardly bent, handle-like flange 18 ends. This particular design of the lower part results in a advantageous dimensional stability and also holds the content to a certain extent Distance from the surface of the sealing wall 16.

As can be clearly seen from the drawing, is for the Distance of the contents from the sealing wall 16 essentially the bar 14 is decisive. Part of this bar is in similarly to the recessed inner surface 10 and the side wall 12 textured or grained. Next is how out 1 and 3, the textured part of the bar can be seen separated from the surface of the sealing wall 16 by a recess 20. This results in the side wall 12 and the bar 14 a favorable profile on which a butter knife or other serving device to remove the contents of the container can be easily cleaned or stripped without accidentally to touch the surface of the sealing wall 16.

The handle-like flange 18 runs around the lower part 8 around and is preferably formed in one piece with the sealing wall 16. It is curved upwards and outwards and thus offers a comfortable finger grip both when the container is open and when it is closed. He also makes one advantageous stiffening of the lower part 8 and in particular holds the sealing wall 16 essentially stable in its position, so that an effective seal between the lower part and the cover can be achieved.

The cover 21 is designed as an open, box-shaped part with a base 22, end walls 24 and side walls 26. Around To simplify cleaning, the connections between these walls are preferably rounded. Between the bottom 22 and the A continuous, outwardly extending flange 28 is provided at the lower edge 30 of the end and side walls. However, the flange 28 is closer to the lower edge 30, which is thereby supported or stiffened. The flange However, 28 does not extend as far outward as the handle-like flange 18 of the lower part, so that the user to lift off the cover place your fingers between the two flanges and at the same time grasp the cover flange 28.

The cover 21 is preferably made of low-density polyethylene, v / o by means of which it is given a certain elasticity and over the lower part 8 can be pushed. The lower inner surfaces of the end and side walls 24 and 26 engage sealingly on the continuously circumferential outer surface of the sealing wall 16 of the lower part. At the same time is through the cantilevered arrangement of the downward-facing sealing wall 16 for this area of the lower part, despite the subsequent Flange 18, additional flexibility is achieved. It should also be noted that the contact zone 32 between the Lid walls 24 and 26 and the viand 16 of the lower part is wide and also conical at an angle of widening of

009840/1263

runs about 2 °. This represents a kind of closing cone, which ensures a reliable seal between the lower part and the cover. The lower part is preferably made 8 made of polypropylene, but other materials with the same good effect can also be used.

The lower part and cover are in pressure connection at the four corners of the lower part. The lid walls 24 and 26 are thereby pulled taut between the four corners so that their inner surfaces lie firmly against the wall 16 between the corners thus providing an effective seal around the entire side wall of the container.

The textured or grained surface shown in FIGS. 1 and 3 offers effective protection against scratching or damage when the lower part is used as a cutting board for the contents of the container, for example butter or cheese. In addition, the surface treated in this way largely prevents the contents in the recessed inner part from slipping as a result of the friction. When a piece of butter, cheese or the like is placed in it, small negative pressure areas form between the substantially smooth surface of the placed piece and the recessed areas between the individual bubbles or grains of the inner surface of the container. M This "vacuum effect ¹¹ " further contributes to preventing the contents from shifting in the container.

The container is particularly suitable for storing perishable food such as butter, cheese, pressed meat or corned beef or the like in the form of elongated pieces, but can obviously also be used to advantage for other dishes Find. Also, a container according to the invention is not limited to details of the shape and / or material of the one shown Embodiment bound.
