Definitions

• the invention relates to a container system for food with the features according to the preamble of claim 1.
• the individual containers are stackable and can be closed in a liquid-tight manner by means of the individual cover.
• the individual cover can be welded or glued as a film to the individual container on a support surface, so that there is the possibility of placing such an individual container with such a cover in a microwave, or of thawing the frozen food in the individual container in warm water.
• the stability of the container is ensured by a support cardboard lying on the inner top side thereof, the support cardboard also serving to enable a corresponding imprint to be made visible on a sliding cover made of transparent material.
• the goods packed in the container should not slip due to an insert arranged in the container.
• DE GM 1946673 describes a deep-drawn container with a reclosable lid.
• the container is provided with a cover film, and after removal of the cover film, which is also partially possible for individual containers of the entire container, which consists of several departments, a part of the filling can be removed and then reclosed.
• the resealable lid is designed as a snap-fit, suitable multiple lid, the snap-in mechanism cooperating with a correspondingly shaped edge area attached to the upper inner edge of the container.
• the resealable cover is sealed with bead-like extensions or with constrictions which fit snugly into corresponding recesses or extensions located in the walls of the deep-drawing container.
• CH 463 376 describes a container which has an inner lid which interacts with the upper edge of the container and an outer lid arranged thereon. A corresponding seal of the reclosable lid takes place between the inner lid and the upper inner edge of the container, the container itself not being subdivided and the upper lid and lower lid not interacting.
• a single cover which is intended to cover a container at the same time and to close it in a liquid-tight manner, considerable design effort is required for the individual container to be closed in a liquid-tight manner.
• These complex designs are costly, especially if the container is to be opened and closed several times.
• the object of the invention is to provide a container system which is stackable and has a single container with a cover, which avoids complex constructions and enables covering and multiple liquid-tight sealing.
• This container system has the advantage that the interaction of the additional cover and the individual cover creates a lock or release of the individual cover, so that it is possible, for example, to cover the individual container with the individual cover for a short-term protection of the food and for long-term protection as it is for transport, storage or for freezing the food is necessary to lock with an additional cover.
• the double cover according to the invention consisting of a single cover and an additional cover, has increased rigidity and ensures improved hygiene protection of the food.
• the container system also has the advantage that it is reusable, so that no packaging waste arises.
• the container system can be handled faster because a single lid does not have a type Vacuum packaging must be pressed onto the individual container.
• the container system can advantageously be produced in space-saving sizes for all freezers and freezer rooms.
• the container system according to the invention offers great advantages, in particular for gastronomy, trade and wholesale, since containers of any size and any number of containers up to transport sizes of euro pallets can be produced or prepared for the respective need. Freezer containers of this type based on the container system according to the invention can be exchanged in the usual deposit system and can be adapted to the respective requirements. This not only advantageously results in cost savings, but also environmentally friendly avoidance of packaging, quick filling and low energy and personnel requirements, since handling is simple and quick to carry out.
• the container system has a plurality of individual containers and devices for tensioning the additional cover and the individual covers, the additional cover selectively locking or releasing the individual covers, so that frozen food from adjacent individual containers, the individual covers of which are locked by the common additional cover, selectively f can be entered, such as with the help of a hot water jet on the back of the respective container. So that the frozen foods are released from one of the containers without the locking of the other individual container being released or even weakened because during the removal of the frozen food from one of the individual containers, the additional cover keeps the individual cover of the other container locked.
• Another advantage of this preferred embodiment is that any number of individual containers can be selectively locked or released under an additional cover can be summarized, and these individual containers combined into containers can in turn be adapted to different needs in the household, catering, retail, wholesale or food industry.
• Individual containers of a container with frozen food for example, can be thawed, and partial removal of frozen food is possible without interrupting the freezing process of the remaining individual containers, so that economical storage is possible.
• each individual container remains hermetically sealed in spite of the common additional cover, there is no taste connection between the individual containers in this container system, so that e.g. it is possible to freeze fish and meat in one container from at least two individual containers without mixing the flavors.
• each individual container has devices for bracing the additional cover and the individual cover.
• each individual cover is preferably provided with such a height, at least in some areas, that when the additional cover is locked, the individual covers seal the individual containers by tightening the additional cover and the individual cover.
• the individual containers have preferably parallel grooves for sliding the additional cover over the individual covers.
• a sliding guide can preferably also be implemented in such a way that corresponding parallel grooves are provided on the additional cover and the additional cover then slides with its grooves along parallel edges of the individual containers.
• the individual container covers can thus also be selectively locked and unlocked one after the other.
• parallel edge areas are provided on the individual containers.
• the additional cover has to be pushed over them one by one to develop their pressing effect on the individual covers.
• the time required for sliding on the additional cover can be shortened by preferably using an additional cover with snap hooks arranged in pairs on opposite edges. These snap hooks can be brought into engagement with edge areas of the individual containers by simply pressing the additional cover onto the individual containers and thus onto the individual covers. Since this process only requires a short pop-up of the additional cover in the area of the snap hooks on the individual containers, and no high-precision sliding process is required to lock the covers together, the time required for closing the container system can be significantly reduced.
• each individual container has a conically shaped interior which widens conically towards the individual cover.
• the conical individual containers are filled with cooked or raw food up to the stop of the lower individual cover, possibly covered with foil and closed with the lower, inner individual cover.
• the outer additional cover is slid in the sliding guide over the individual cover as far as it will go, and firmly closes all departments of the container system.
• Containers with food to be frozen are then frozen. If you only need the food from a single container for thawing, you open the additional cover up to this container, remove the inner individual cover, tip the container over and spray the individual container of the container system with hot water, for example. This frees the frozen food from the individual container, which is sprayed with hot water, and can then be processed further.
• the container system can then be closed again with the additional cover without the remaining foodstuffs having been thawed in the remaining individual containers belonging to the additional cover.
• a cooked menu can be filled with meat, sauce, vegetables, pasta, dumplings, etc., frozen and then, after selective removal from the container system, heated in a microwave device.
• different individual container sizes and also a total number of containers per additional cover can be varied.
• each individual container preferably has a support for the Single cover with recessed circulation groove. With this circulating hat, the individual cover can engage in a form-fitting and liquid-tight manner, especially as soon as the additional cover is locked.
• the additional cover can have bulges in the region of each individual cover, which press the individual cover against the containers in a sealing manner.
• each individual cover can have a curvature which interacts positively with the additional cover in such a way that the additional cover held by receiving devices of the individual containers presses the individual cover onto the individual container.
• This solution has the advantage that the additional cover can be designed relatively simply as a plate, while each individual cover must be shaped appropriately.
• Such a bulge on each individual cover can preferably be designed as a handle for the individual cover, the handle being designed as a spherical cap on its upper side and being deflectable from the additional cover in the direction of the individual container. If this deflection takes place with the aid of the additional cover, the individual cover is advantageously pressed onto the individual container in a liquid-sealing manner via the handle.
• a preferred embodiment of the bulge provides that it is designed as a flat spherical cap with a preferred spherical radius of 50 to 200 mm and that it can be deflected up to 10 mm in the direction of the individual container by means of the additional cover.
• the spherical cap can simultaneously cause the individual cover to be pressed securely against the individual container.
• the spherical cap-shaped design of the bulge also has the advantage that when the additional cover is moved by sliding it can be pushed onto the spherical cap at a flat angle, so that the sliding forces remain controllable.
• the container system according to the invention can be joined very stably if the individual containers together form an integral object.
• the individual containers can have, for example, common partition walls or they can be connected to form a one-piece object via the slide rails for the sliding attachment of the additional cover.
• the one-piece construction can easily be achieved by an injection molding process.
• the one-piece object can preferably have continuous opposite rails which have opposite grooves for receiving the additional cover and for slidingly guiding the additional cover over the individual covers.
• This preferred embodiment has the advantage that a relatively simply structured additional cover can be used.
• the additional cover can have profiled structures, preferably in the form of embossed or embossed folds or ribs on its outside, so that the bottom surfaces of the containers find a secure hold on the additional cover.
• the one-piece object can have edges in the area of the covers which extend outwards in such a way that they correspond to the internal dimensions of standardized hot-air ovens in commercial kitchens.
• This has the advantage that entire batteries of frozen food can be pushed into the convection ovens in order to be defrosted for a large guest table at the same time.
• the one-piece object can fold or Have ribs in the area of the cover, which correspond to the outer contour of the bottom structure of the object with a precise fit. In this case, the containers only need to be stacked on top of one another, the external dimensions only having to be smaller than the internal dimensions of the standardized hot-air ovens.
• the covers are preferably made of a hard plastic polypropylene.
• the container system must consist of heat and cold-resistant plastics for operating temperatures between -40 ° C and 120 ° C.
• a container system made of such plastics for frozen foods is preferably used as a freezer-container system for the household, catering, retail or the food industry.
