Definitions

  • Container for dishes with bottom and lid parts and elastic connecting body.
  • 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 12.
  • 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 the destination, the dishes are then served in the containers for the sake of simplicity.
  • Such containers are used today for 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” foods.
  • the container is designed as a disposable item.
  • these containers have generally been produced in one piece from plastic with at least one fold line as the folding axis, as a result of which two folding parts are created which act as the base or cover 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 bottom part, are equipped with an edging section, by means of which the corresponding other part is closed off from the outside of the container.
  • a simple, often used locking device is e.g. of projections extending away from the edge of the cover or of the 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. Since such containers are also generally made of easily fragile material, such as 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. The tab then partially breaks off completely when opened.
  • easily fragile material such as foamed polystyrene
  • a disadvantage of these conventional food containers is therefore that the folding parts held together by the locking device just illustrated do not have optimal sealing properties, that the locking device and the container as a whole can generally only be used once and is used as a disposable tray.
  • the object of the present invention is to create 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.
  • the base and cover part are shaped identically, the cover part being brought upside down when being joined together.
  • the identical design of the base and the cover part has the advantage that only one shape is required for the production.
  • the molded part can be used dual-function as either a bottom or a lid part. Thus, the manufacturing costs can 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.
  • a connecting body is arranged between the base and lid part, which runs around the at least one recess designed as a storage section (three recesses 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 connecting body ensures an airtight closure of the food to the outside, so that an additional closing 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 connecting body preferably in the form of a sealing ring, whereby the container can be completely sealed to the outside in the assembled state.
  • the container forms a particularly stable unit with a completely sealing sealing ring, so that the container is easy to handle and easy to transport.
  • 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 makes it possible in a simple manner to cut the border of the bottom cover part between the leg sections of the H cross-sectional profile bring the sealing ring and receive positively according to claim 4.
  • the H cross-sectional profile thus creates an exact mutual positioning of the parts held together, without additional guide units, such as guide pins.
  • this shaping serves on the one hand for easy removal of the food from the depressions and for a better removal from the mold ⁇ position.
  • this edge design of the depression exerts a radially inward pull on the web of the H cross-section, whereby the parts of the container are held securely to one another and fixed.
  • the radial clamping of the container parts is thus achieved in that the leg sections of the H cross-sectional profile are elastically deformed by the inclination of the surrounding wall sections, which increases the distance between the lower and upper leg sections.
  • the leg sections try to counteract the expansion that is forcedly imposed, as a result of which the leg sections put the web of the H cross section under tension.
  • the border 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 bevelled 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, whereby the container can be hermetically and airtightly closed.

  • the base or cover part is made from melamine resin, the production costs are relatively low and there is the further advantage that, in the case of a multi-cavity shell, the webs formed between two depressions are of the same height as the border They can do what benefits the sealing of the depressions from one another without having to make the connecting body more complex.
  • the development according to claim 9 has the advantage that if the web has essentially the same height as the border, the sealing ring does not have to be provided with different compensation sections in order to ensure a complete seal.

Abstract

L'invention concerne un récipient (1) pour aliments, notamment pour servir, conserver et transporter des aliments, qui comprend au moins un fond (1B) et un couvercle (1A) dans lesquels est formée au moins une cavité (5, 5a, 5b, 5c) se présentant sous forme de plat, lesdites cavités se superposant symétriquement à fleur. Le fond et le couvercle sont formés de manière identique et sont maintenus par un élément de jonction (3) situé entre eux, qui entoure la (au moins une) cavité et qui se présente sous forme d'une bague d'étanchéité qui subit une déformation élastique au moins par endroits. Cette configuration permet d'obtenir une unité stable facile à assembler et qui enferme hermétiquement les aliments. Comme la garniture d'étanchéité a une section transversale profilée en H, les bords du fond et du couvercle peuvent s'intégrer par liaison de forme entre les branches de la section transversale profilée en H sans nécessiter l'utilisation d'un dispositif de fermeture supplémentaire. Ce mécanisme de fermeture peut être débloqué par des gestes simples pour dissocier les parties individuelles afin de pouvoir les laver séparément. Le fond et le couvercle étant de plus réalisés dans un matériau réutilisable résistant aux éraflures et anti-usure, comme de la résine mélaminée, ils peuvent être utilisés à diverses reprises de manière à ce que le récipient serve de plat à usages multiples. La structure identique du fond et du couvercle présente de plus l'avantage de pouvoir maintenir des frais de production extrêmement bas et de pouvoir empiler aisément lesdites parties du récipient, de manière à ce que lorsqu'elles ne sont pas utilisées, elles puissent être stockées en prenant le moins de place possible.
