Definitions

  • Container for food in particular for serving, storing and transporting, and associated connecting bodies
  • the invention relates to a container for food, in particular for serving, storing and transporting food or the like according to the preamble of claim 1, and to a connecting and sealing body according to the preamble of claim 29.
  • Such containers are used, for example, to contain food so that they can be removed from the place of manufacture, e.g. a commercial kitchen, can be transported to the destination, the food in the containers should be kept in the manufacturing state for a long time. Arrived at a destination, the dishes are then served in the containers for the sake of simplicity.
  • Such containers are used today in the care of old people's homes, hospitals, canteens or the like. Furthermore, such containers are known as packaging material for so-called "fast food” food.
  • the container is designed as a disposable item.
  • these containers have generally been made in one piece from plastic with at least one fold line as the folding axis, as a result of which two folding parts be created, which act as the bottom or lid part of the container.
  • these folding parts are provided with storage sections in the form of depressions which are separated from one another by webs.
  • One of the two parts, often the base part, is equipped with an enclosure section, via which the container part is sealed off from the outside by accommodating the corresponding other part.
  • a simple, often used locking device is e.g. from projections extending away from the edge of the cover or bottom part, one of the projections being provided with a slot to form a type of tab so that the other projection can be received therein.
  • Such containers can only be used once, so that enormous amounts of waste are generated. Furthermore, since such containers are usually made of easily fragile material, e.g. foamed polystyrene, and one of the protrusions has to be pressed from a substantially horizontal plane into a substantially vertical plane, the tab at the kink is often overstressed. Sometimes the tab breaks off completely when opening.
  • easily fragile material e.g. foamed polystyrene
  • a disadvantage of these conventional containers for food is therefore that the folding parts held together by the locking device just shown do not have optimal sealing properties, and that the locking device and the container as a whole are in the Can only be used once and is used as a disposable bowl.
  • Such containers could also be made of reusable material, e.g. Ceramics.
  • reusable material e.g. Ceramics.
  • this requires a high manufacturing effort in the form of separate molds for the lid and the bottom part.
  • the object of the present invention is to provide a container for food according to the preamble of claim 1, which can be used as a reusable tray, but is simple and economical to manufacture and still ensures a good closure of the food to the outside. Another object is to create an economically producible and permanently usable connecting body with which food containers can be put together simply and safely.
  • a connecting body arranged between the base and lid part is used for closing and sealing the container, which runs around the at least one depression designed as a storage section (three depressions in a shell are shown in FIGS. 1).
  • the firm connection and also the sealing of the individual recesses from one another takes place in that the cross section of the connecting body is elastically deformed, at least in some areas.
  • this connector body is a airtight closure of the dishes to the outside and also with each other is guaranteed, whereby an additional locking device is no longer required.
  • these individual parts of the container are easy to handle and simple to separate from one another, so that each individual part can be cleaned separately and is then ready for use again.
  • the container according to the invention for meals as a reusable bowl is unproblematic and economical to use. Because, according to the invention, no more distinction is made between the bottom part and the lid part of the container, the life of the container parts is also increased. Because the dishes can be cut equally in the lid and in the bottom part. According to the invention there is therefore no container part which would be exposed to increased scratching and / or cutting stress from cutlery.

  • the molded part can be used dual-function as either a bottom or a lid part. The manufacturing costs can thus be kept extremely low, even if more expensive, reusable materials are used.
  • the identical design of the base and cover part has the additional advantage that in the event of loss or destruction, in particular of several cover parts, the remaining base parts can be put together again to form a usable container. Likewise, there is no need to pay attention to the numerical equality of base or cover parts when returning. In addition, a simple stackability is achieved due to the identical design, so that the base and cover parts can be stored in a space-saving manner when not in use.
  • the cross-sectional profile of the sealing ring can be designed in various ways. It proves to be particularly advantageous, however, to provide the sealing ring with an H cross-sectional profile according to claim 3, because this creates the possibility in a simple manner of inserting the border of the base cover part between the leg portions of the H cross-sectional profile of the sealing ring and according to claim 4 positively.
  • the H cross-sectional profile thus creates an exact mutual position positioning of the parts held together, without additional guide units, e.g. Guide pins.

  • the edging edge is supported between the leg sections of the H cross section on one side with its lateral end face on the outer leg section and on the other side with its beveled wall section on the elastically deformed leg section.
  • the tension caused by the inclination of the wall sections ensures that the border with the sealing ring comes into a completely sealing contact, so that the container can be hermetically and airtightly closed.
  • the sealing ring of an additional development according to claim 7 is provided with special locking sections in the area of the outer sealing legs, then the holding function for holding the bottom and the bottom together can be carried out in a simple manner Lid part can be improved.

A kind of snap connection or snap closure can thereby be produced.
  • projections are preferably formed on the inside of these locking sections, which are used to snap the rim of the base part to the outside Snap the leg of the H behind the edge of the bezel.
  • the trough can also be formed in the longitudinal direction of the chamfering edge, in order to create the prerequisite for the fact that the bordering edge of the base part can be made somewhat wider at the corresponding locking area, as a result of which a reliable snap connection is provided even in the case of manufacturing-related dimensional differences.
  • the locking section according to claim 12 is only provided on the sections where the container is touched for opening, the opening of the container is facilitated. It has been shown that this type of locking ensures a sufficiently high sealing force over the entire circumference, in particular, if the material for the cover part is chosen to be firmer, for example from the group of polypropylenes.
  • the opening of the container is not impaired in the event of any constraints, particularly in the corner areas. This measure also ensures that the user of the container according to the invention does not have to additionally grip around when opening, in order to also detach the partial sections of the bordering edge that still remain in the snap connection.
  • the above-described opening of the container is made even easier with the development according to claim 14.

  • the cover part with the sealing ring can be easily removed horizontally when opened by reaching behind the tabs without running the risk that the cover part after the sudden release of the rear handle is too fast tilts away from the bottom part. This is because the relevant pairs of forces acting on the locking sections during the opening process generate opposing moments, which are compensated for when the cover part is lifted off.
  • the release of the locking sections from the border edge of the base part can be further favored with the development according to claim 18. This is because the sealing leg can be more easily pulled or bent in the area of the locking section by gripping the tab.

  • the sealing ring is designed with a U-profile, the base of the U-profile also being corrugated.
  • Figure 18 shows the position of the sealing ring in the assembled state of the container again. In this case too, a holding or sealing function is achieved by contacting the leg regions of the sealing ring.
  • handle tabs 82, 84 are indicated by dash-dotted lines, which are integrally formed on the peripheral edge 86 of the sealing ring 3 (or 3A).
  • the tabs 82, 84 extend over the entire height H of the profile, ie over the entire height of the profile legs 20A and 22A.
  • the locations at which the grip tabs 82, 84 are formed are symmetrical with respect to a central or dotted line Level of symmetry Eg of the container contour, which coincides with the contour of the sealing ring 3.
  • the grip tabs are preferably located where the circumference 86 of the sealing ring 3 merges into the sealing web 88.
  • the sealing ring 3 has increased stability, so that when the grip tabs 82, 84 are gripped to open the container, the elastic material of the sealing ring can be twisted. As a result, the frictional contact between the legs of the sealing ring and the container parts can be reliably removed with relatively little effort, so that even older and weak people can easily lift the cover part with the sealing ring off the bottom part. It has been shown that it is advantageous for handling the container when it is opened to move the grip tabs 82, 84 slightly out of the center of the side walls 90, 92, for example at the end of the third on the left in FIG Sidewall 90, 92.
  • handle flaps 82, 84 do not change the handling described above for opening the container.
  • the handle tabs 82, 84 produce a favorable leverage effect, which can also be controlled by the shape of the handle tabs 82, 84. It has been shown that grip tabs 82, 84 with a cross-sectional area of 2 to 3 cm 2 are sufficient to increase the leverage to such an extent that easy loosening of even tightly tightened sealing rings is made possible.
  • the grip tabs 82, 84 on the legs 20A, 22A over the entire height HG.
  • the connecting body with holes so that after the rinsing no rinsing water can collect in the H cross-sectional profile of the connecting body.
  • These holes can preferably cross the outer leg sections directly above and below the crossbar and are provided in particular in the corner regions of the connecting body.
  • the invention thus creates a container of food, in particular for serving, storing and transporting food, with at least one base part and one cover part, in which at least one bowl-shaped depression is formed in flush opposite position.
  • the base and cover parts are expediently shaped identically and are held together by a connecting body arranged between them and running around the at least one depression, in the form of a sealing ring, under its at least partially elastic deformation.
  • This construction creates a stable unit that is easy to assemble and that seals the food hermetically and airtight. Since the sealing ring has an H cross-sectional profile, the edging edges of the base or cover part between the leg sections of the H cross-sectional profile can be positively accommodated without the need for an additional closing device. This locking mechanism can then be released by simple manipulations so that the individual parts can be separated from one another in order to be cleaned separately. Furthermore, since the bottom or cover part made of recyclable, scratch-resistant and wear-free material, such as. B. melamine resin, the bottom or cover parts can be used several times, so that the container can be used as a reusable tray.
  • the identical design of the base or cover part also has the advantage that the manufacturing costs can be kept extremely low and easy stacking can be achieved, so that the base or cover parts can be stored in a space-saving manner when not in use.
  • the bottom or cover part with a Provide insulating body to counteract the heat loss.

Abstract

Un récipient (1), utile notamment pour servir, conserver et transporter des aliments, comprend au moins un fond (1B) et un couvercle (1A) pourvus de cavités (5A) en vis-à-vis en forme de coquille. Le fond et le couvercle sont retenus ensemble par un élément de liaison (3) sous forme d'un anneau d'étanchéité situé entre le fond et le couvercle, qui s'étend autour des cavités (5A) et qui se déforme élastiquement au moins en partie. On obtient ainsi une unité stable simple à assembler et qui renferme les aliments de manière hermétique et étanche à l'air. Etant donné que l'anneau d'étanchéité présente un profil transversal en H, les bordures du fond et du couvercle peuvent s'insérer par liaison de forme entre les sections des branches du profil transversal en H, sans dispositifs de fermeture supplémentaires. Ce mécanisme de fermeture peut être défait en un tour de main afin de séparer les parties individuelles du récipient et de les laver séparément. Le fond et le couvercle sont en outre pourvus de corps isolants afin de réduire la dissipation de chaleur.
