Description

FIELD OF THE INVENTION

The present invention relates to a lid portion of a container.

WO2007 / 142522 of the present applicant discloses such a lid portion. In the container assembly described in this application, the container assembly has a peripheral wall, which can be made essentially of cardboard, coated with a material to isolate the peripheral wall from the contents of the container, and a lid attached to the rim of the container assembly. The applicant uses a container for powdered milk for baby food. The lid portion has a connecting portion and a lid that is pivotally or rotatably attached to the connecting portion. The cover rests on the connecting portion. Closing the lid on the connecting portion can be improved.

WO2008 / 034172 discloses a resealable flexible container lid with a rotatable second portion. The second section closes around the rim surrounding the opening of the container. This disclosure calls this "ring extension." The rim forms a part of the wall of the tank, made as a whole. The second portion should rotate around, or rotate relative to, the first portion attached to the lid. This requires the actual properties of rubber. This design defines the condition for the lid, in particular when maintaining frequent opening and closing, at the same time, maintaining a good seal is required. In addition, the cover is not hinged to the rest.

EP-1.625.948 discloses a packaging for liquid paint, which has a plastic wall with a peripheral rim, made as a whole. It contains a plastic cover having a wall with a groove for receiving the flange and an inner peripheral edge that is fixed under said peripheral flange, providing a latch function. The lid does not rotatably attach to the rest of the package.

JP-2004-001815 discloses a plastic container having a separate lid. The disclosed embodiments have several interconnected rims and peripheral protrusions and corresponding grooves that make these covers too laborious to open for everyday use.

For example, JP-2006-282199 discloses a container for powdered milk. The tank has a separate cover. This lid has a second peripheral edge attached to the outer wall of the container and a first peripheral edge attached to the lid. A peripheral removable belt connects the first and second edge. The first edge has an inner protrusion that engages in a peripheral protruding portion on the outside of the container wall.

US-6.889.867 discloses a plastic container that includes a lid with a hinged closure to seal the closure of the container to prevent moisture loss, i.e. moisture coming out of the tank. The lid is placed above the rest of the container and rotates, leading to the connection of the threads. The sealing of the lid on the rest of the tank is achieved by the edge. In addition, the lid has a relatively small round dispensing opening having a wall with grooves through which cleaning wipes can pass and be removed from the container. The dispensing opening has a peripheral wall for receiving with the possibility of sealing the peripheral wall of the hinged closing element. The lid is configured to maintain humidity inside the container. For this, the hole is round and provided as small as possible.

US4284200 describes a dispensing closure that is not accessible for children to open. The lid has a rim and the hole is surrounded by a rim. Both rims have an ongoing protrusion such that the lid snaps onto the rim surrounding the hole. The lid has an eyelet that is so close to the hinge axis that lever means are necessary in order to open the lid, thus providing for a closing device that is not accessible for children to open.

US6761279 describes packaging for viscous foods. This package has a container and a closing device mounted on the container. The closing device is presented in the form of a base and a cover. The base has special means for interacting with the means on the container to attach the base to the container so that the rim of the container remains free to seal the sealing membrane on the rim. Fasteners make this packaging relatively complex. In addition, the seal of the lid can be improved. In addition, stacking these packages on top of each other may interfere with the sealing of the lid.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a lid part for a container that easily opens and closes during everyday use.

Another objective of the present invention is to provide a lid part that provides a good, preferably hermetic seal of the container, preferably also after frequent daily use.

Another objective of the present invention is to provide a lid portion that provides a container that forms a minimum amount of waste.

According to a first aspect of the present invention, it is implemented by means of a lid part for a container, said lid part being made of thermoplastic material and comprising a connecting section for attaching to the rim of the container assembly and a lid that is rotatably connected to said connecting section,

said connecting portion comprising an inlet and a peripheral first flange surrounding said inlet,

said lid comprising a peripheral rim of the lid protruding to said connecting portion,

the perimeters of said lid flange and the first flange are mutually agreed to allow said lid to close sealed on said first flange of the connecting portion,

and the area of said inlet is at least about 50 cm ² .

In one embodiment, the present invention relates to packaging for powdered baby food. In such a package, it is important that foreign objects do not fall into the package and do not clog the powder. On the other hand, the packaging must be reopened.

The powdered infant formula is usually removed from the container using a measuring spoon. A measuring spoon is often contained in the package. Therefore, in order to properly remove the powder from the container, the inlet should be as large as possible.

All these requirements are difficult to combine in one separate tank. For example, the easiest way to ensure good compaction of the contents is to make the inlet, however, as small as possible. In this case, a more reliable seal is usually achieved using a (semi-) permanent closure.

The lid portion according to the present invention, however, makes this possible. The present invention provides a lid portion for a container with an inlet that is large enough so that contents (e.g., powder) can be scooped out of the container, while providing a seal that effectively reduces the access of foreign objects. Surprisingly, it turned out that the real lid with a large inlet can be re-closed, while providing a good seal.

The lid portion of the present invention provides a reliable seal that prevents foreign objects from entering the container that closes it. Often, however, the lid for the lid portion must open and close often many times a day and provide good sealing after frequent use. Preferably, the compaction is achieved in a simple way. In fact, it was found that in the embodiment, about 2-5 N would be acceptable for the opening force. For a closing force in an embodiment, a force of about 6-15 N would be acceptable.

Since the device closing the container must be discarded, it is preferable that it is inexpensive to manufacture in large quantities and provides a minimum of waste. In addition, it would be useful if the lid part was easily controllable in the manufacture as well as in the manufacture of the entire container. In addition, a good seal is especially desirable if the contents of the package are hygroscopic. A more reliable closing device will reduce the exchange of air (with a high water content) between the inside and outside of the package, thereby reducing the formation of lumps in absorbent material, for example, powdered milk for baby food. Therefore, the present invention is particularly useful when storing powdered milk for baby food in tropical climates.

The lid part according to the present invention can be used for containers, for example, with a cardboard wall, but is not limited to such use. Typically, such a cardboard wall is coated or provided with one or more sealing layers to isolate the contents of the container from environmental influences. An example of such packaging is disclosed in WO2005075314 and WO2007142522, registered on the applicant. For reasons in which this makes sense, these documents are incorporated herein by reference in their entirety.

A specially adapted lid part is used together with a powder storage container. Indeed, it is well suited for storing hygroscopic powder, in particular food products like milk for baby food. Opening and closing manually preferably requires very limited force and / or force. Preferably, the lid can be opened manually with one hand. In particular, it is suitable for packaging powdered milk for baby food, as the mother can preferably open and close the package while supporting the baby.

In order to avoid intensive contact of the hand with the contents, the lid is preferably provided with clamping means for fixing and holding the measuring spoon or ladle. This further limits the choice of sizes. Therefore, the size of the handle of such a spoon is limited. On the other hand, this may also limit the size of the packaging container. The spoon handle in the embodiment is long enough to allow a person to reach the bottom of the container. In an embodiment, said peripheral first flange has a first perimeter near said connecting portion and a second perimeter near a rim of said flange at the end of said flange at a distance from said connecting portion, said second circumference of the peripheral first flange being larger than its first perimeter, and

said lid has a first inner perimeter near said lid and a second inner perimeter near a rim of said lid flange, said second inner perimeter of said lid being smaller than said first perimeter near a rim of said lid flange, said perimeters of said lid flange and first rim are mutually agreed in order to allow said lid to be sealed tightly on said first side of said connecting portion using its a rim of a lid surrounding said first rim. This allows easy closing and opening, especially with daily use. In addition, by sealing the lid flange around the first flange, it is easier to release the lid portion of the lid after molding.

The first flange at the connecting portion together with the flange of the lid in the embodiment provides a seal with a locking latch. The corresponding lid flange (sealing lip on the lid) is thus interlocked by another, first flange, so that a corresponding sealing interaction is ensured. This sealing interaction can provide a suitable tight pressure to prevent the entry or exit of moist air from the tank, or it can be implemented to guarantee a sufficiently small maximum clearance to prevent foreign objects from entering the tank. These elements also allow for the provision of compaction using conventional structural plastics and can help to avoid the additional costs of elastomeric materials produced by multicomponent injection molding.

In addition, in an embodiment, the lid flange and lid flange, which may also be referred to as pull-out and snap-on edge elements, respectively, may be interchangeable with the ability to affect the same mechanism and / or two “draw-out” elements may be used instead. Note that the exhaust element can have the same curvature on the inner and outer wall, which provides for its manufacture by injection molding so that the element can be removed from the mold without special floating rods and, therefore, allows faster cooling, shorter cycle times and, thus lower cost. In addition, the design of these sealing elements provides for the stable operation of the sealing latches for holes with a relatively large diameter.

In addition, the design of the flanges or snap-fit sealing elements can be adjusted to suit satisfactory sealing characteristics, the corresponding opening force and the corresponding closing force. The locking provided by the seal with a latch also prevents the lid from opening, partially or completely, or from the possibility of being partially open at the moment when the package is broken by external forces. If necessary, the specified curvature, angle and non-rectangular geometry of the sides (exhaust and sealing edge elements) and their interaction in assembled form can be adjusted with the possibility of changing the sealing pressure, the opening and closing forces.

In an embodiment, the inlet area is at least about 60 cm ² . This provides even better hand access. In an embodiment, the inlet area is at least about 75 cm ² .

In an embodiment, the inlet area is less than about 250 cm ² . Thus, it is possible to provide easy access for the hand of an adult and at the same time provide a lid with the possibility of sealed closing in a simple action. In an embodiment, the inlet area is less than about 200 cm ² . These upper and lower limits provide a good compromise between easy access for a person’s hand, sufficient strength, good closure and the ability to provide a bucket or spoon that can be held in the lid and reach the bottom of the container assembly.

In an embodiment of the present invention, said first rim delimits said inlet. This can further increase the rigidity of the lid portion.

In an embodiment, said first rim expands or straightens at a distance from the inlet, thereby increasing the perimeter of said first rim.

In an embodiment, said circumferential first rim around its circumference at its outer periphery thickens around or on said rim of said first rim. Alternatively, or in addition, the inner periphery of the lid flange thickens around or on said rim.

In an embodiment, said second inner perimeter of said lid flange is 2-7% smaller than said first perimeter of said connecting portion. In particular, it was found that, being made of a thermoplastic material, it provides good sealing, while remaining easy enough to open.

In an embodiment, said inlet is substantially circular or substantially elliptical. This will in most cases provide a waterproof seal. In some applications, even a rectangular opening with rounded corners may be acceptable given the degree of compaction. These shapes provide a good seal. In order to provide a moisture-tight seal for hygroscopic powders, it is preferable if large straight parts are avoided in the inlet or the first flange and the lid.

In an embodiment, the area of said inlet is at least 50% of the area of the connecting portion. This provides ample space to allow the hand to pass with the bucket to reach the contents. On the other hand, this provides a reliable seal and allows fixing on the inside of the lid of the corresponding bucket or spoon.

In an embodiment, the area of said inlet is about 60-70% of the area of the connecting portion. Obviously, this is a suitable choice.

In an embodiment, the inner diameter of the inlet is about 9-13 cm. In an embodiment, the diameter of the connecting portion is about 10-13 cm. These dimensions provide reliable sealing and a sufficient volume of the container.

In an embodiment, said lid flange is made of thermoplastic material, allowing its perimeters to increase when placing said lid on said flange, and in which said first and second perimeter of said lid flange, if said lid does not cover said opening, is smaller than the perimeters of said first side.

In an embodiment, said thickness of said first rim, taking into account its thermoplastic material, is selected to provide a rigid rim.

In an embodiment, said cap portion is made of a thermoplastic polymer selected from the group consisting of polyethylene (PE) and polypropylene (PP). These materials are easy to obtain and to process. In addition, these materials provide a degree of flexibility and elasticity that allows reliable sealing and daily use. If desired, some parts of the lid part may be made of a more flexible, rubber material during two-part molding. The lid flange closing around the first flange may, for example, be molded from a more flexible polymer material, which material is essentially known in the art. Alternatively, the end portion of the lid portion may be made of a more elastic, rubber material. This can be manufactured in a two-component molding process.

In an embodiment, said lid is made of a thermoplastic material having such elasticity that hermetically seals said lid at said connecting portion by said lid flange on said first rim.

In an embodiment, said connecting portion comprises a wall provided with said inlet, and said first rim extends from said wall, said wall and said lid, when closing said inlet, provides closure for the upper part of said capacitive part.

In an embodiment, said connecting portion comprises a peripheral rim that has a peripheral groove for receiving said rim of said capacitive portion. In an embodiment, the described area of said peripheral rim is larger than the area of the inlet.

In an embodiment, said connecting portion comprises stacking tabs. In another embodiment, said stacking protrusions are provided at locations around the first flange. These protrusions allow lid parts to be stacked on top of each other during the manufacture of containers, as well as stacking containers. The position of the protrusions prevents the load on the cover and the impact in the lateral direction.

In addition, the present invention relates to a container assembly comprising a capacitive portion with a peripheral wall and a lower wall, and a lid portion comprising a connecting portion for connecting to a rim of said peripheral wall and a lid that is rotatably connected to said connecting portion, wherein said connecting portion comprises an upper wall provided with an inlet that can be sealed by said cover, and said connecting portion provided n stacker means which surround the said inlet opening and which cooperate with the stacking means on the bottom portion of said capacitive parts.

Alternatively, it is an object of the present invention to improve the closure of a container assembly.

According to this aspect of the present invention, it is implemented using a container assembly comprising a capacitive portion with a peripheral wall and a lower wall, and wherein the lid portion includes a connecting portion for attaching to the rim of said peripheral wall and a lid that is rotatably connected to said connecting a section, said connecting section comprising an upper wall provided with an inlet that can be sealed by said lid, and first connecting portion is provided with the stacker means, which enclose said inlet opening and which cooperate with the stacking means on the bottom portion of said capacitive parts.

In addition, the present invention provides a lid portion for a container assembly, wherein the lid portion includes a connecting portion for attaching to the rim of said capacitive portion and a lid that is rotatably connected to said connecting portion, said connecting portion comprising a peripheral U-shaped rim to accommodate the upper edge of the side wall of the capacitive part, in which the inner wall of the said U-shaped rim contains stiffeners, extending beyond bare legs of said U-shaped rim, and said connecting portion comprises a peripheral abutment surface defined by an upper surface of said lid portion, said stiffening ribs and said abutment surface being mutually arranged such that when said lid portion is laid on the second lid portion, extending lower ends said stiffeners are supported on said peripheral abutment surface of said second lid portion, while protecting the legs of said The U-shaped rim of said lid portion from said peripheral abutment surface of said second lid portion.

The data of the invention describe everything related to the improvement of the closure device of the container. In fact, all of them are associated with increased reliability of this closing device. In this invention, styling means are provided in such a way that they enclose the lid when it seals the inlet. Thus, styling means at the connecting portion are arranged around the inlet. Therefore, when the containers are assembled one above the other, they do not create a load on the lid with a force that can break the seal. Since the containers are often used for powdered milk for children and infants, for example, it is very important that the collection container is sealed and remains sealed.

In an embodiment, said laying means at said connecting section comprise protrusions. These protrusions can be made in a simple way, for example, in the form of extended wall elements. Alternatively, one or more rims may be provided around the inlet. Such rims are arranged so that they provide opening and access to the lid for opening and closing.

In an embodiment, said protrusions are located at the corners of a rectangle that encloses said lid while sealing said inlet. When placing styling means on the connecting portion in this way, it can be possible to stack without rotation.

In an embodiment, the height of said protrusions is at least equal to the height of said cover when sealing said inlet. In fact, when the laying means at the connecting portion are at least as high as the lid, they protect the lower portion of the next container assembly laid on top of the container assembly, even from touching the cover.

In an embodiment, said connecting portion comprises a peripheral rim for receiving an upper edge of a side wall of said capacitive part in a groove, wherein the inner perimeter of said rim is interconnected with a perimeter enclosing said laying means of said lid part to provide additional laying means for placing a number of lid caps on top of each other parts of the cover. Thus, the laying means at the connecting portion have a functional purpose during manufacture, i.e. storage of lid parts stacked on top of each other and with the possibility of positioning, and subsequently - storage of complete containers safely stacked without load on the lids.

In an embodiment of a cover with a U-shaped rim, said abutment surface is attached to said U-shaped rim and defines an inlet that is closed by said cover. In addition, the present invention relates to a container comprising a lid part as described above and a capacitive part in which said capacitive part comprises a lower portion and a peripheral wall of the container connected to said lower portion ending in a rim for receiving said lid part.

The various aspects discussed in this patent can be combined to provide additional benefits. Some aspects described in this description, shown in the drawings or described in the claims, may form part of the highlighted application.

Detailed Description of Preferred Embodiments

Figure 1 shows the container assembly 1 with the lid part 2 of the present invention. The container has a capacitive part 3. The capacitive part 3 can be made of cardboard coated with a synthetic coating layer known in the art in order to make it suitable for containing food or liquids. The capacitive part can also be made of plastic or metal. Preferably, it is used to hold food or liquids. In an embodiment, the capacitive portion 3 may have a synthetic coating layer on its inner surface, and the sealing foil of the sealing membrane is attached below the rim or the edge of the capacitive portion 3, in the embodiment about 1-3 cm below the edge. The sealing foil can be attached to the inner surface of the capacitive part 3, for example, by thermal sealing. Thus, some space may be provided between the lid and the seal for storing, for example, a measuring blade or spoon.

The lid part 2 is further detailed in FIGS. 2 and 3, showing a 3D view of the lid part 2 with the lid 4 open on top (FIG. 2) and below (FIG. 3). The lid part 2 includes a connecting portion 5, a flexible hinge 9 and a cover 4. Thus, the cover 4 is rotatably connected to the connecting portion 5. The connecting portion 5 defines the inlet 6. In this embodiment, the first edge 7 defines the opening 6. Cover 4 provided with a flange 8 of the lid, which is fitted to the first flange 7 for closing the inlet 6 and for sealing the container assembly 1. In this embodiment, the inlet 6 may also be round. Alternatively, it may be square with rounded corners. However, it is important in all three embodiments that the lid flange 8 is mounted around the flange 7 so that the inlet 6 can be sealed.

In addition, the connecting portion 5 comprises a wall 11, which is provided with said inlet 6. On the wall 11, protruding elements 14 are provided. The use of such protrusions 14 is similar to that explained in WO2007142522 of the present applicant. These protrusions 14 provide an element of the laying means for laying the lid parts on top of each other during manufacture. In addition, these protrusions 14 provide an element of the stacking means for stacking the finished containers in assembly, for example, in storage rooms. In this embodiment, the protrusions 14 are located on the connecting portion 5. The advantage of this is that the cover 4 is not exposed to the load. Thus, the quality of closing cannot be compromised. In addition, the height of the lid 4 in the closed position is equal to or substantially equal to the height of the protrusions 14. Thus, when the containers are assembled stacked on top of each other, the weight of the containers will keep the caps tightly pressed while preventing loads in other directions.

In addition, the connecting portion 5 is provided with a peripheral rim 12, which may be called a U-shaped rim. It has a groove 13 for accommodating the upper edge of the side wall of the capacitive part 3. The fixing of the connecting portion 5 to the wall of the tank can be improved by any means known from the prior art. In an embodiment, hot glue is provided in groove 13.

Figure 4 depicts a bottom view of the lid part 2 with the lid closed. The cross section is shown in this drawing. This section is additionally depicted in figure 5. This section shows more clearly how the flange 8 of the lid 4 closes on the flange 7 of the connecting portion 5. This is shown in more detail in Fig. 7.

Figure 5 also more clearly depicts the rim 12 of the connecting section. In the drawing according to figure 5 shows the ribs 20 stiffness, which give additional rigidity to the rim 12.

Fig.6 depicts the side 8 of the lid, which closes on the side 7 of the capacitive part 5. The side 8 of the cover is installed with compression around the side 7 of the connecting portion 5. In the position of figure 7, when the cover is closed on the connecting portion 5, the perimeter on the edge of the side 7 equal to the (inner) perimeter of the lid flange 8 in position 22. In position 16, the lid flange 8 is thickened. Side 7 straightens. It is configured in such a way that its outer peripheral surface is adjacent to the inner peripheral surface of the lid flange 8. Side 8 of the cover is made of thermoplastic material. This provides some degree of elasticity. In particular, at this point the lid flange has a thickness taking into account the elasticity of the thermoplastic material used. The lid flange 8 is installed with a certain degree of elasticity around a relatively rigid flange 7. In order to close the lid and facilitate the possibility of doing this often, the lower end of the lid flange 8 has a beveled edge. This makes it easier to snap the edge of the lid flange 8 around the edge of the flange 7. When not mounted on the flange 7, the lid, and in particular the lid flange 8, is dimensioned such that the smallest inner perimeter of the flange rim is smaller than the smallest (described or external) perimeter of the flange 7. It is preferable that the outer perimeter of the bead 7 at the edge 15 is larger than the inner perimeter of the bead 8 of the lid at position 22. Thus, the lid 4 cannot spontaneously come off. In an embodiment, the bead 7 is aligned. The shape of the lid flange repeats this form or takes it with a slight tightness. The lid flange 8 extends slightly with the possibility of elastic installation around the flange 7. This makes a tight seal possible. In practice, for example, in the embodiment depicted in the drawings, the smallest diameter of the edge 7 is 101.89 mm, the largest diameter is 112.65 mm. In an embodiment, the thermoplastic material is polypropylene (PP). In this case, the inner diameters of the lid are, for example, 101.36 mm and 112.12 mm. Outer diameters are, for example, 104.0 mm and 114.8 mm. For this material, the thinnest part of the lid flange 8, D1, may be about 0.7-0.8 mm, and the thickest part, D2, about 1.1-1.2 mm. The height of the lid flange is about 3.9-4.5 mm, and the height of the corresponding flange 7 is about 2.9-3.1 mm. In practice, the diameter of the lid flange will be about 3-7% smaller than the corresponding diameter of the flange 7. In practice, the lid flange 8 will taper slightly inward, with an angle of about 2-5 degrees. Due to its elasticity, the lid flange 8 when closing around the first flange 7 will be slightly stretched, and the lid flange 8 will no longer taper and fit snugly around the first flange 7. In the drawing, the interacting narrowed shapes of the lid flange 8 and flange 7 allow the lid to be pulled onto the outer the surface of the wall 11 of the connecting section in order to provide additional sealing of the edge of the flange 8 of the cover and the surface 11 of the wall.

In order to provide the lid flange 8 with some elasticity, at the same time provide the connecting section and, in particular, its flange 7 with sufficient stiffness and provide inexpensive manufacturing of the lid part and in large quantities, in the embodiment of the lid part, are made of thermoplastic material. In particular, it is made of polyethylene (PE) or polypropylene (PP). The material in the embodiment is flexible and flexible enough to allow the lid flange 8 to stretch around the flange 7. Thus, a tight seal is possible.

In an embodiment, the volume of the container having the lid portion is about 0.5-2 liters. This volume is determined by the depth, width and height of the tank. In order to be able to provide a measuring bucket having a length long enough to reach the bottom of the vessel inside the vessel, one of the sizes of the diagonal section, or width or depth, is preferably of the same order of magnitude as the height of the vessel. In addition, it is preferable if the bucket can be attached to the inside of the lid. In practice, a container can have a depth of about 9-13 cm, a width of about 11-16 cm, and a height of about 10-18 cm. A bucket or spoon will have a total length of about 9-11 cm. Thus, the inlet should have the largest diameter at least about 9-11 cm, depending on the full length of the spoon or bucket used. The area of the inlet 6 will at least be about 50% of the cross-sectional area of the container provided by the lid portion. The upper limit that can be achieved will be about 85%. In the above example, this value will be about 60-70%. This will provide a sufficiently large cover, both in area and in maximum diameter. At the same time, this will provide sufficient space to accommodate the laying protrusions 14 on the connecting portion 5.

A large inlet is preferred for easy access with a bucket. In addition, for hygienic reasons, when a filled container is offered to the public in the store, the bucket may be provided attached in clips located on the inside of the lid or between the lid and the product seal, which is additionally provided in the container under the lid (i.e. in the space located between the cover and the seal for the product). In an embodiment, the lid has at least minimum dimensions to accommodate a bucket.

For easy opening, said lid 4 comprises an opening protrusion 21, at this point attached to the edge of the lid flange 8. The opening protrusion 21 is located on its edge, blocked by the tamper strip 22. This strip 22 has protrusions capturing the edge of the opening protrusion 21. The strip 22 is attached to the connecting portion 5 by means of thin jumpers made of material. These jumpers must be thin enough to collapse if the opening protrusion 21 passes the protrusions of the strip 22.

7 depicts two lid parts 2, 2 ′ stacked on top of one another. The protrusions 14 on the connecting portion 5 provide a safe laying on top of each other with the possibility of setting the position of the lid parts in the manufacture of complete containers, while avoiding the loading of the lid 4. Here, the laying lugs are placed on the wall 11. In fact, as already indicated in figure 1 , the first purpose of the protrusions 14 is to provide one element of the laying means, which functions together with complementary laying means in the lower section of the capacitive part, in particular, on the bottom part. This allows safe stacking of several containers on top of each other. In addition, since styling means on the lid part are provided on the connecting portion around the lid (in the closed position), when stacking containers assembled with lid parts stacked on top of each other, closing the lid is not broken. Indeed, in the embodiment shown, laying means on the lid portion extend slightly above the lid in order to further provide closure or so as not to disturb the closure.

The second purpose of the laying means on the roof part is carried out if the placement of these laying means is coordinated with the size of the connecting section. Thus, the above effect and the purpose of the laying cover parts are realized.

The placement of the styling means 14 at the connecting portion is such that the container assembly laid on the lid portion cannot be rotated. Those. it cannot rotate around an axis perpendicular to the inlet. To this end, protrusions 14 in this embodiment are provided in the corners of a (virtual) rectangle. Additional laying means on the bottom of the capacitive part provide support on the sides of the rectangle opposite the laying means 14 on the lid part 2.

In this embodiment, styling means on the capacitive portion are provided with a peripheral rim on the bottom of the capacitive portion, as shown in FIG.

It will also be apparent that the foregoing description and drawings are provided to illustrate several embodiments of the present invention and do not limit the scope of protection. Based on this disclosure, many more embodiments will be apparent to those skilled in the art that are within the protection scope and spirit of the present invention and which are obvious combinations of prior art technology and the disclosure of the present patent.
