Description

The present invention relates to a packaging container, in particular for foodstuffs, comprising a receptacle for storing goods forming container and a lid which can be fixed to an upper edge of the container both as slip lid and as a clamping lid, wherein the packaging container for fixing the lid as Slip lid at least on the side of the lid has a locking means and for fixing the lid as a clamping cover, both the lid and the container in a clamping system can be brought together clamping surfaces.

Articles according to the preamble of claim 1 are the NL 2006482 C as well as the EP 1854733 A1 refer to. Such type of preferably plastic-made packages are widely used in the food industry. A disadvantage of the cited prior art, however, is that often with a pressure on the lid in the direction of the container bottom, a transition from a Stülpstellung to a clamping position is too easy. If, for improved transportation, air-tight storage of the product and / or formation of a tamper-evident seal, the container of the packaging container is sealed with a sealing foil arranged on the upper edge, the latter can be pushed downwards in the direction of a lower contact surface if the lid is overloaded Parts of the lid can be damaged. Damage to the tamper-evident closure may, however, be accompanied by leakage of liquids, it may spoil food, which invalidates the product.

It is therefore an object of the present invention to provide an article according to the preamble of claim 1 in such a way that the transition from the Stülp- to the clamping position occurs less easily and in particular when using a sealing foil arranged on the upper edge damage during a Stülpstellung is avoided ,

According to the invention, it is provided that an article according to the preamble of claim 1 is characterized in that the lid and container support surfaces which are formed in the Stülpstellung the lid for supporting each other and of which at least one adjacent to a clamping surface. Regardless of whether the support surfaces now abut each other or are spaced from each other in the Stülpstellung, in the case of a load on the lid from above and in the direction of a lower support level or the container bottom support of the support surfaces carried on each other. It is understood that the wall thicknesses of the lid and container are designed so that a transition to a clamping position is still possible. In order to enable a transition to the clamping position and the functionality of the clamping cover, at least one of the support surfaces is formed adjacent to a clamping surface, so that from a certain pressure on the lid in the direction of a lower contact plane, the upper edge of the container widens or yields and thus the clamping position is reached.

Under an upper edge of the container, generally the uppermost part of the container, together with e.g. Any sealing and clamping surfaces and outer edges and any other functional parts of the container, which allow the connection to the lid understood.

If there is a sealing foil that seals the receiving space, the lid should be used as a slip-on lid. By using a sealing foil at the upper edge of this and with it the associated support surfaces is stabilized. After removing the sealing film, the lid of the packaging container is used as a clamping cover for the particularly tight closing of the receiving space.

Adjacent to one another are, in particular, those surfaces which, for example, merge into one another only over a small corner radius. However, larger transition areas between clamping and support surface may also be present, wherein clamping surfaces of the cover rest against clamping surfaces of the container, at least for a short time, prior to taking a (final) clamping position. Clamping surfaces are therefore also such surfaces that reach not only in the clamping end position of the clamping cover but also on the way there in contact with the lid or the container.

Preferably, both the lid and the container each have a support surface which adjoins a clamping surface, so that complementary areas of container and lid are provided to complement each other. Clamping and support surfaces are formed in close proximity to each other, which favors a compact design of the upper edge of the container and the lid.

In particular, the support surfaces each directly adjoin a corresponding clamping surface, wherein directly by, for example, a sharp corner transition or a corner transition is to be understood with a small radius. However, also clamping and support surfaces adjacent to each other, the curved or angularly adjacent to each other and merging surface areas.

Supports supporting surfaces can have a support area running continuously along the edge of the container. However, a packaging container according to the invention can also have support areas which are separated from one another for sufficient support along the container rim.

Advantageously, at least one of the support surfaces is formed at least substantially parallel to the flat, lower contact plane of the packaging container. This is in particular a support surface of the container, however, both the support surface of the container as well as the support surface of the lid may be formed substantially parallel to a lower support level of the packaging container to produce an optimal support of the support surfaces to each other. A power transmission from the lid in the edge is quite possible. For example, the support surface of the lid is the underside of a substantially flat or flat lid bottom, which can preferably be supported in its edge region on an inner edge region of an upper flange of the container forming the support surface of the container. The lid bottom is essentially even or flat even if it has, for example, central or concentric arranged bulges which are based on manufacturing or design technology, wherein the curvature merges into a parallel surface at least in an outermost edge region of the bottom to the lower contact surface.

Advantageously, the clamping surface of the container is formed from an inner side of a side wall of the container and the clamping surface of the lid from an outwardly directed surface of the lid. Widening of the container to take the clamping position is easier due to the over the lid larger dimensions of the container as a compression of the lid.

Preferably, at least one of the support surfaces at least partially forms a sealing surface for a sealing film. This is in particular the support surface of the container, on which then a seal can be made. Although it is also conceivable that the sealing film is attached to both the container and to the lid, in particular the stiffening of an upper container edge by attaching the sealing film is useful to avoid a bending apart of the upper edge region in order to take a clamping position of the lid. In this respect, if the sealing film is present, the packaging container can be transported without damage with regard to the tamper-evident closure, since the supporting surfaces in the event of a pressure load are supported in the presence of the sealing foil and over each other. In the closed position of the lid, it is then supported at least partially on the part of the sealing film arranged on a support surface. In particular, the support surfaces are designed to support one another in such a way that, in the case of a force acting in the direction of a bottom of the container or a lower support level on the lid and before taking the clamping position, the force is at least partially transferred into the edge of the container. This is done before damage to the sealing film.

Advantageously, the packaging container is further distinguished by the fact that, in relation to a lower contact plane, the area of the opening through which a part of the lid is to be moved in order to assume its clamping position is smaller than the surface of the lid initially to be moved through the opening Part of the lid. The container must forcibly expand, for which the wall thickness is adjusted according to the opening width. By leading to the clamping position, a preferential movement in the direction of the clamping position is initiated in particular in combination with inclined clamping surfaces.

The adoption of a clamping position is therefore also easily possible if a clamping surface is inclined relative to a perpendicular to a contact plane, wherein the clamping surface of the lid or the clamping surface of the container is inclined starting from the adjacent support surface inwardly. By an initial widening of the upper edge of the container, possibly also by a compression of the upper edge of the lid, the clamping lid can engage in an undercut in order to assume a tight clamping position. To limit the clamping, the lid preferably has a stop which ensures optimum positioning. The perpendicular is formed for example by a longitudinal central axis of the packaging container, which is perpendicular to the lower Aufstandsebene.

The handling of the packaging container according to the invention is further improved if the lid has on the upper side an internal shoulder for abutment of a support surface of another lid, so that a plurality of lids can be stacked in a filling system. Internal lying in the present case means that the paragraph is offset from the outermost peripheral edge inwards. Preferably, the heel is located in a lid rim or bead on the same side facing the longitudinal central axis of the packaging container.

Furthermore, it is sufficient for the invention, if the on a perpendicular to the lower Aufstandsebene projected distance between the support surface of the lid and bottom of the paragraph at least substantially corresponds to the distance of the locking means to a clamping position limiting stop of the lid. As a result, the stacked lid can not only be supported on the inner or outer heel. It is achieved a more stable and sustainable stacking column, so that a larger number of lids stacked on top of each other or can be inserted in a magazine of a processing plant.

If appropriate, functionally equivalent elements are provided with identical reference numbers.

An inventive packaging container 1 includes a container 2 and a lid 3 which is at an upper edge of the container 2 can be fixed as slip-on lid as well as clamping lid. In 1 the lid is in the Stülpposition and thus used as a slip lid. To fix the lid 3 as slip lid are on the side of the lid locking means 4 present, the outside an upper edge 6 of the container 2 to take action 2 ). To fix the lid as a clamping cover both have the lid 3 as well as the container 2 in a clamping system can be brought together clamping surfaces 7 respectively. 8th on ( 3 ). Both the lid 3 as well as the container 2 have support surfaces 9 respectively. 10 on, which are designed to support each other and on clamping surfaces 7 and 8th adjoin. The packaging container 1 stands on a surface that is a lower riot level 5 formed.

The clamping and support surfaces 7 - 10 border directly on each other across the corner. The corner is located in the transition between a more vertically employed, slightly inclined downwards wall section 17 of the lid 3 that the clamping surface 7 forms, and by a bottom of a lid bottom 15 , which is horizontal to the lower riot level 5 runs, trained support surface 10 , The corner has, for example, in relation to a curvature of the locking means 4 or a curvature of a shoulder 14 a small radius of curvature. This rounding can at the transition between the slip-to the clamping position of the lid 3 (Transition between 2 and 3 ) Also serve as a clamping surface, since there is already a Aneinanderklemmen lid 3 and containers 2 when transferring the lid 3 takes place in the clamping position. Accordingly, the clamping surfaces 7 . 8th also not necessarily be straight but also be bent, for example, for a Schnans snapping. A clamping position would then be more secure, but the lid could be pulled off worse.

The lid edge has a shoulder 11 on, with their bottom a stop for the top 12 of the container edge 6 formed. By the defined stop the user is signaled that the lid has reached its clamping position.

About a distance A between the support surface 10 and shoulder 11 projected onto a perpendicular to the lower riot level 5 , thus the strength of the clamping can be defined. The vertical is, for example, by the longitudinal central axis 20 educated. The support according to 2 of the lid 3 on the upper, even part of the edge 6 of the container 2 causes in the event of a burden on the lid 3 towards a bottom of the container 2 before taking the clamping position, the force at least partially into the edge of the container 2 is transferred. An expansion of the clear cross section of the upper container 2 is through a sealing foil 13 prevents, which covers the receiving space and on which the lid 3 can support without the sealing film 13 can be damaged. In the case of sealed film 13 closed receiving space, the lid is supported 3 thus on one on the edge of the container 6 arranged part of the sealing film 13 and then continue on the upper edge of the container.

The clamping surface of the container 2 is over the inside of one over a shoulder 14 outwardly offset side wall 16 of the container 2 educated. The clamping surface 7 the lid is from an outwardly facing surface of the lid 3 that part of the top wall 17 is, trained. Instead of an arrangement of the sealing film 13 on the sealing surface at least partially with forming support surface 9 could be at a more pronounced shoulder 14 the sealing film even at then reduced receiving space inside the container 2 on the shoulder 14 be put on. The support surface 9 is at least partially part of the upper, planar edge 6 of the container 2 ,

Toward the lower riot level 5 are both the sidewall 16 with the associated clamping surface 8th as well as the clamping surface 7 having lower part of a top wall 17 from the longitudinal central axis 20 of the packaging container 1 that are perpendicular to the lower riot level 5 stands and forms a perpendicular to this, inclined downwards towards the outside. In this respect, when a transfer of the lid 3 from the Stülpposition into a clamping position with the concomitant expansion of the upper container edge and then a deeper engaging lid 3 Successful relaxation of the upper container edge promoted taking the final clamping position.

The lid 3 has an inside heel on the top 18 on that for the support surface 10 an overlying, present in a cover stack lid forms a seat ( 4 ). At the same time corresponds to a distance B between a contact area of the locking means 4 and the shoulder 11 at least substantially a distance C between the shoulder 18 and the lower support surface 10 of the lid 3 , As a result, a safer stacking is guaranteed in the lid stack. The lid 3 sits more stable in the stack. The support surface 10 and latching means 4 are used not only for taking the clamping and Stülpstellung but also for the stacking of the lid.

In the embodiment according to 5 are further, the clamping position of the lid assigned latching means 19 in the form of knobs or alternatively webs present, which are above the locking means provided for the Stülpstellung 4 in an outer lid edge 21 are arranged. While initially the Plülpstellung the lid 3 between the locking means 4 and 19 is fixed, is about the sliding down of the lid 3 in the clamping position by engaging under the outside of the edge 6 through the locking means 19 the clamping position also secured.

The packaging containers according to the invention can be produced both in the deep-drawing process as well as in the injection molding or blow molding, wherein the illustrated embodiments of a packaging container 1 not just have to have a square basic shape. Rather, round or polygonal basic shapes are usable. The number of locking means 4 is to be adjusted accordingly, also the size of the support surfaces 9 . 10 , In particular, the present embodiments of inventive packaging containers 1 in the corner areas several locking means 4 while on the long side walls of the container 2 on the side of the lid 3 an elongated locking means 4 is available.
