Description

[0001] The invention relates to a receiving container with at least two joinable container parts for receiving edible and inedible goods, which have interlocking locking elements with the aid of which the two container parts can be held in a closed position after joining, and the locking elements consist of a first locking element provided on the inside of the first container part or lid and a second locking element formed by the outer end or outer edge of a rim part of the second container part or container shell.

[0002] It is already common practice in the packaging industry to manufacture and distribute disposable or to-go containers for holding and / or transporting food or other items. These disposable containers are molded bodies consisting of several parts, including two parts designed to be joined together. These molded bodies feature locking elements along their outer edges, allowing the two container parts to be connected. However, existing locking mechanisms, such as snap closures, do not provide sufficient protection against leakage.

[0003] Furthermore, a molded body, in particular a container, is known (DE 39 27 062 A1) which can be produced using the sheathing of new palm leaves and / or the bract of a palm flower. The palm can be a so-called pinnate palm, such as the betel nut palm. It is advantageous if the container is made exclusively from the leaf material of the sheathing and / or the material of the bract. The container can consist of several parts that are suitably joined together, one part being designed as a lid and / or closure. The method used to produce the container includes cutting the material of the sheathing or bract, pressing the material in a suitable molding press, and drying.The invention generally discloses the use of the covering of new leaves of a palm tree and / or the bract of the flower of a palm tree for the production of shaped bodies, preferably containers.

[0004] The invention (CN 201810460477.6) relates to the field of tableware and discloses a disposable betel nut leaf flour box comprising a box lid and a box body. The box body and lid are integrally or detachably connected, and the lid and body are hot-pressed and thermoformed using a betel nut leaf. The invention further discloses a processing method for the disposable betel nut leaf flour box.

[0005] The disposable betel nut leaf meal box and its processing method offer the following advantages and effects: The solution utilizes a novel mechanical structure, effectively reducing pollution and providing an environmentally friendly, green, and safe disposable meal box. The container is intended to improve people's living standards. Made from leaves, it is easily biodegradable after use, thus protecting the environment. The lid can be secured with a locking mechanism. This mechanism consists of a round pin located on the inside of the lid. When the lid is closed, this pin must be pressed behind the horizontally protruding rim to lock it in place.The design of the rim of the tray and lid is not suitable for repeated use of the locking mechanism, as the pin would be very easily damaged or break off with repeated use. Since the tray in question is a disposable tray, the locking mechanism appears to be adequate for single use, but completely inadequate for repeated use.

[0006] The invention is based on the objective of designing the receiving container with the associated container parts and the closure device in such a way that it can be used several times without further ado, without the closing effect diminishing even after repeated use.

[0007] The object is achieved according to the invention in that the edge region or the outer edge part of the first or upper container part or lid has a curved or S-shaped profile and the outer end of the edge part of the second container part or the container shell has a curved or arched profile, wherein when the lid and the container shell are joined, the container shell is guided along the curved or arched outer surface of the first locking element.

[0008] The inventive design of the edge areas of the container parts, which can be joined to form a receiving container, makes the locking device very easy to handle, since the inventive sliding surfaces ensure that when joining the container parts, at least one adjustable locking element can be easily guided along the fixed, curved locking element until it reaches its locking position and also generates the required contact pressure, especially since the edge areas of the container parts are spring-elastic.

[0009] It is also advantageous that the rim of the second container section has a convex or curved bulge oriented towards a cavity. The curved shape of the rims of the container sections significantly contributes to the fact that the lid can be secured to the container shell without requiring much force, while also ensuring that the individual locking elements are not damaged.

[0010] It is also advantageous that the first locking element is located in a transition area between an upper part and a lower part of the cover.

[0011] Furthermore, it is advantageous that the outer boundary or circumferential surface of the first securing element is curved or at least has a partially spherical shape.

[0012] It is also advantageous that the edge areas of the container parts are elastically designed and that the edge area of ​​the second container part or the container shell has a curved or curved shape pointing inwards towards the center of the container.

[0013] In a further embodiment of the invention, it is advantageous that numerous locking elements, spaced apart from one another, are provided on the inside of the first container part. This further improves the tightness of the joined container parts.

[0014] For this purpose, it is advantageous that the S-shaped curve of the container part or lid, or the edge area of ​​the lid, transitions into a straight, flat part of the lid, allowing numerous container parts or the entire receiving container to be placed on top of each other or stacked.

[0015] Furthermore, it is advantageous that the container part or container tray has a roughly flat bottom with one or more recesses on the inside into which protruding studs on the outside of the bottom of another container tray can engage or lock securely when the container trays or the entire receiving container with lid are placed on top of each other. The container bottom can also be curved.

[0016] This locking mechanism can be easily opened and re-closed. The high contact pressure of the upper part of the molded body against the lower part, achieved by the locking mechanism, ensures maximum tightness when the molded body is closed, despite manufacturing tolerances inherent in the natural raw material. The shape of the lid and the use of the container's curves contribute to a tight seal between both parts, even with permissible manufacturing tolerances. This protects the contents of the molded body from environmental influences such as temperature differences, contamination, and leakage during transport.

[0017] Ease of use is achieved through the trough-like recesses in the container, which also allow the containers to be stacked with or without lids. This also ensures improved transport safety, as the studs can lock into the recesses, securing the containers with or without lids in a vertical or horizontal direction.

[0018] Further advantages and details of the invention are explained in the patent claims and in the description and illustrated in the figures.

[0019] This shows: Fig. 1 a partial view of the edge areas of the lid and container; Fig. 2 a sectional view of the lid and container in the open state; Fig. 3 receiving containers (1) with at least two joinable container parts; Fig. 4 a partial view of the edge area of ​​the lid; Fig. 5 A perspective view of the lower container shell from above.

[0020] The in Fig. 2 and Fig. The container 1 shown in Figure 3 consists of at least two connectable container parts 2 and 3, namely a lid 2 and a container tray for holding edible and non-edible goods. These parts have interlocking locking elements 4, which, after assembly, hold the two container parts 2 and 3 in a closed position. The container can be used indefinitely, as the wear of the locking elements is extremely low.

[0021] The securing elements 4 consist of a first securing element 5 provided on an inner side 19 of the first container part or the lid 2 and a second securing element 6 formed by the outer end or outer edge 8 of an edge part 18 of the second container part or the container shell 3.

[0022] The edge area or outer edge part of the first or upper container part or lid 2 has a curved or S-shaped profile, and the outer end 8 of the edge part of the second container part or container shell 3 has a curved or simple curved profile 17.

[0023] When the lid 2 and the container shell 3 are joined together, a second locking element is easily guided along the first locking element 5 provided on the curved or curved outer surface.

[0024] The edge part 18 of the second container part 3 has a curved or curved bulge which is oriented towards a cavity 9 and thus significantly improves the clamping effect of the locking element 6 and increases the contact pressure of the edge area 8 against the inner side of the curved section 17 of the edge area 18 of the container 3.

[0025] On the inside 19 of the first container part 2, numerous locking elements 5 are provided at a distance from each other, with the help of which the contact pressure between lid and container shell is improved.

[0026] The S-shaped contour 17 of the container part or lid 2 or the edge area of ​​the lid transitions into a straight flat part 13 of the lid, so that numerous container parts 3 or container trays can be placed on top of each other or stacked.

[0027] The container part or container tray 3 has an approximately flat base 14, which has one or more recesses 15 on its inner surface. Protruding studs 16 on the outer surface of the base 14 of another container tray 3 can engage or lock securely into these recesses when the container trays 3 are placed on top of each other. The recesses, in conjunction with the studs, secure the container parts during transport. Reference symbol list 1 collection container 2.
