Description

Container components for storage and/or transport by assembly

technical field

The invention relates to an assembly of containers, in particular cylindrical, or substantially cylindrical in shape, rectangular or substantially rectangular, for storage and/or transport by assembly, in particular by stacking or stacking.

More precisely, the invention relates to a container assembly, containers of said type each comprising: a receptacle comprising a transverse wall formed by a base provided with one or more identical or different holding means; and a cover comprising a transverse wall formed by a top provided with one or more same or different holding means, the dimensions of the base and the top of the same container being similar to each other but are different from container to container, and the retaining means at the top of each cover are adapted to correspond by engaging each with a retaining means - having a complementary shape and located at the base of each receptacle co-operate to form one or more sets of complementary profile retaining means within said container assembly.

Background technique

Storage of percussion instruments such as bass drums, snare drums, cymbals or tambourines is usually accomplished by containers shaped to fit the item to be stored. The variety of percussion instruments and their shapes, which sometimes vary widely, necessitates the use of containers of varying sizes. The transport of components of the same variety of containers is usually achieved by stacking them in the form of pyramids. Despite the good centering of the containers with their adjacent containers on the lower level, the stability of a described modular system is not secure and can cause serious drawbacks, for example when tilting of the stack appears unavoidable , and/or when the assembly is subjected to acceleration or deceleration of a transport vehicle.

As an example, a stack of pyramids for containers in the cosmetics sector is described in DE 20011 097 U1.

The containers are all similar in shape but differ in size, and each container is fitted with a removable lid. On the other hand, the bottom of each container is externally provided with a recessed portion adapted to cooperate with a raised portion provided adjacent to the lower lid to prevent movement of said container on said lid.

Furthermore, the containers and lids of a said stack are placed one above the other along a central axis of symmetry so that the stack formed is in the form of a regular pyramid. However, such configurations should in some cases be avoided because of instability problems, especially when a said stack is transported in an inclined position.

Contents of the invention

The object of the present invention is to provide a container assembly of the above-mentioned type, which overcomes the above-mentioned drawbacks, that is, it consists of modular elements of simple design and sufficient stability - so as to constitute in particular a stack that can be moved without major difficulties Body - composition.

To this end, the container according to the invention is characterized in that the transverse wall of each cover and the transverse wall of each receptacle complement each other externally and peripherally by stabilizing means which themselves are equipped with holding means; and when When said retaining means at said cover and said retaining means at the transverse walls of said receptacle belong to the same group of retaining means of complementary shape, on the one hand retaining means and stabilizing means at each transverse wall of said cover, and On the other hand the holding means and the stabilizing means at each transverse wall of said receptacle are equidistant from each other.

Thus, the containers according to the invention each comprise a cover and a receptacle, said cover and receptacle each comprising a transverse wall provided with stabilizing means, said stabilizing means themselves Equipped with holding device.

The cover and receptacle are complemented by a side skirt (for the cover) and a skirt (for the receptacle) along the The perimeter of the transverse wall and its stabilizing means extends, and the side panels fit around the perimeter of the transversal wall and its stabilizing means of the receptacle.

However, the containers according to the invention belonging to the same assembly differ substantially from each other in the dimensions of their lid tops and their receptacle bases, and the general shape of their perimeters may be the same or different.

More precisely, inside a said assembly, the lid top and receptacle base of the same container are generally of the same size, but the dimensions vary between different containers of the assembly, while the lid top of the same container The periphery of the receptacle base and the receptacle base generally have the same configuration, which configuration may vary between different receptacles of the assembly.

For example, where each of the containers is provided with a lid top and a receptacle base, both of which are circular and of the same diameter, but which differ from one container to the other, the containers may A container assembly according to the present invention is constituted. Likewise, another container assembly according to the invention may for example consist of containers each having a lid top and a receptacle base, both rectangular and of the same size, but one container Relative to another container size is not the same.

However, containers - the top of the lid and the base of the receptacle having the same general shape, such as a circle; A container assembly according to the present invention.

Thus, in the ensuing description and claims, the expression "dimensions of a container" means that the lid top and receptacle base of a container of the present invention have similar dimensions.

Said containers according to the invention belonging to the same assembly can be assembled in a particularly advantageous manner by juxtaposition, in particular in that the top of the lid of one container is combined with the base of the receptacle of another container superimposed on it - - Its dimensions are smaller - the assembly is carried out according to a vertical axis and if desired can be repeated in a continuous manner for the other containers of the assembly in order to form an assembly by stacking.

However, another type of combination can also be implemented by utilizing the top of a first container and the receptacle base of a second container, and by juxtaposing them along a horizontal axis, and if necessary successively arranging the Repeat for the other containers of the component. In this case, the assembly takes the form of a column of juxtaposed containers.

According to a particular embodiment, containers belonging to the same module can be used as base or support for a plurality of different stacks of containers included in said module. This is the case, for example, of a container whose overall shape is rectangular, which supports a stack of containers at both ends of its top.

In any case, in combinations of the type described, the dimensions of the base of each juxtaposed container are smaller than the dimensions of the adjacent container here, ie the top of the underlying container, when a stack is involved.

Regardless of whether stacking or alignment is involved, containers according to the invention are assembled by juxtaposition - the size of their base being smaller than the size of the top of another lid immediately adjacent to the container, requiring the use of suitable means to ensure an effective retention in place and restraint. Lateral movement by sliding, especially when juxtaposed containers are stacked on top of another container according to the invention. To this end, the retaining means provided at the top of the lid of the larger size container are designed to cooperate with the retaining means at the base of the receptacle immediately adjacent to the container.

Said retaining means take the form of a first part consisting of a protuberance projecting from the outer surface of the lid top of a container and adapted to be released by contact. Cooperate with a second part formed by a recessed portion formed on the outer surface of the base of the receptacle of an adjacent container. The holding means can be compared with each other due to the complementarity of their external shapes. fit, and thus constitute a pair of retaining means complementary in shape to each other, which together ensure maximum contact through scarfing.

The retaining devices whose external shapes are complementary to each other will be denoted "complementary retaining devices" hereinafter.

On the other hand, in the interior of the container assembly according to the present invention, each cover top is provided with a similar holding member, and each receptacle base also has a similar holding member, and the latter has an outer shape similar to that of the cover. The outer shape of the retaining means at the top is complementary. In this way, the retaining means at the top of each cover can cooperate with the retaining means at the base of each receptacle to form similar complementary retaining means pairs, the retaining means assembly forming a complementary retaining means set.

In particular it follows that the flat transverse walls of the lid and of the receptacle of the same container - they have the same dimensions, the same peripheral configuration and each is provided with complementary retaining means - the external shape will fully complement each other. Said characteristics can be verified at each container of said assembly, regardless of its own size.

However, in some cases, the base of the receptacle of the container may not be provided with a retaining device, especially when the container constitutes a modular base of a stack without any underlying container corresponding to the modular base. Apposition.

Due to the above-mentioned features, it thus appears possible to add or subtract one or more containers in the inventive combination, such as a stack, of containers belonging to the same module.

In general, in order to increase the stability of the juxtaposed containers in a said assembly, in particular obtained by stacking, the lid top and the receptacle base of the containers of the same assembly are preferably provided with a plurality of shapes complementary to each other. The set of holding means, said complementary shape may be the same or different for different sets of holding means.

The number of complementary retaining means at the container of the invention is preferably 1 to 7, eg 3 to 5, per lid top or per receptacle base.

Thus, in the following description and claims, the term "transverse walls of complementary shape" denotes a cover transverse wall and a receptacle transverse wall, the top and corresponding base of which are provided with one or more complementary retaining means.

According to another characteristic of the invention, said complementary holding means are constituted by:

At the cover, constituted by one or more raised motifs coming from the top plane, formed by protuberances whose flat tops lie parallel to the cover in at least one plane on the top of the piece,

At the receptacle, constituted by one or more hollow-outs from the base plane, formed by a recessed portion whose flat bottom lies parallel to at least one of the bases of the receptacle plane,

The retaining devices are adapted to cooperate with each other by engaging.

In order to increase the stability of an assembly of containers of different sizes belonging to the same assembly, according to the invention, one or more stabilizing means, advantageously similar stabilizing means, are provided at the receptacle and at the cover of each container, so that Ensures the maximum stability sought.

Thus, according to another characteristic of the invention, the stabilizing means are formed as follows: on the one hand by at least two projections of the transverse wall of the cover, usually two projections, in particular of the top plane; On the one hand, it is formed by at least two protrusions of the transversal wall of the receptacle, generally two protrusions, in particular at least two protrusions of the base plane.

According to a supplementary feature of the invention, said projections come, on the one hand, from a plane located at the top of the cover and including said top and a plane including said plane - which determines the distance of a protrusion from said cover and on the other hand from a plane at and including the base of the receptacle and a plane including and including the plane - which determines the distance of a recessed portion from the receptacle The flat bottom farthest from the base of the seat -- between.

Furthermore, according to another characteristic of the invention, when said protrusion does not constitute an extension of said cover top or said receptacle base, said protrusion comes from a plane, said plane preferably belonging to said A holding means for the top or said base.

According to a preferred embodiment, the protrusion at the transversal wall of the cover comes from the top plane, while the protrusion at the transversal wall of the receptacle comes from the plane defining the flat bottom furthest from the base.

The retaining means provided at the cover and the transversal walls of the receptacle are generally similar to the retaining means at the top of the cover and at the base of the receptacle, respectively.

Advantageously and according to another characteristic of the invention, the retaining means provided at the stabilizing means, such as the protrusion of the top plane and which complement the transverse wall of the cover, have an external shape, for example, substantially frustoconical and the retaining means at the stabilizing means—for example, a protrusion of the base plane, which complements the transverse wall of the receptacle—is formed by a hole whose shape is complementary or substantially complementary to the external shape of the stud. The grooves are formed so that the different holding devices can be effectively fitted together by engagement.

The bore is generally embodied as the inside of a tubular end portion forming a seat, which can itself also be partly hollowed out, if desired.

According to a preferred embodiment, the retaining means at the protrusion of the top plane of the cover are constituted by the aforementioned studs, while at the protrusion - which comes from the plane defining the flat bottom furthest from the base of the receptacle - The retaining means at are then formed by the aforementioned tubular end portions, said retaining means being adapted to cooperate with each other by scarfing.

Alternatively, the retaining means at the protrusion of the transversal wall of the receptacle, such as the protrusion of the base plane, is constituted by the above-mentioned post; and the protrusion provided on the transverse wall of the cover, such as the top plane The retaining means at the protruding part are formed by the above-mentioned complementary shaped holes, and the retaining means are adapted to cooperate with each other by crimping.

On the other hand, in order to further improve the stability of the assembly by stacking or aligning containers of different sizes belonging to the same assembly, according to the invention, said one or more holding means arranged on top of said cover and arranged on The one or more holding means of the receptacle base are arranged in a particularly advantageous manner.

Thus, in a general manner, the holding means are arranged such that, at the top of the lid or at the base of the receptacle of the same container, a constant distance separates the holding means on the top surface and the extension of the lid on the one hand. member transverse wall - preferably the top of the cover - the stabilizing means are separated, and on the other hand complementary retaining means on the surface of the base and extend the receptacle transverse wall - in particular to determine the distance The plane of the flat bottom farthest from the base--separated from the stabilizing means.

Said features are all verified for the same set of complementary retaining means inside the same container assembly according to the invention.

Thus according to the invention, the complementary holding means belonging to several groups are distributed such that: for each group of holding means, said distances are separated by:

On the one hand, holding means at the transverse walls of the cover, especially at the top, and stabilizing means extending said transverse walls, and

On the other hand, holding means at the transverse walls of the receptacle, in particular at the plane defining the flat bottom furthest from said base, and stabilizing means extending said transverse walls,

The distance is the same for each group while varying from group to group.

Likewise, in a container assembly of the same assembly, regardless of the size of said container, one or more complementary retaining means are formed from the retaining means by engaging complementary retaining means at the juxtaposed lid and receptacle groups, and distributed in said assembly in one or more rectilinear columns parallel to the columns formed by the stabilizing means and their own holding means.

The combination of containers according to the invention belonging to the same assembly is implemented by means of retaining means arranged on the one hand at the top of the cover of a first container and on the other hand at the stabilizing means extending the cover and this is done by correspondingly engaging in the holding device at the base of the receptacle of a second container and in the holding device at the stabilizing device extending said receptacle.

This operation can be repeated for one or more other containers of the assembly, starting from the lid of the second container and/or the base of the first container to form a composite whose The base size is larger than the top size.

In said combination - whether it involves stacking or alignment - each container is offset from the center relative to the adjacent container, and this is the direction towards the stabilizing means of the adjacent container, which itself Aligned in a common plane, and when assembled, each retaining means of the lid of a container cooperates, if possible, with a complementary retaining means of the receptacle of the juxtaposed container.

Therefore, according to another object, the invention relates to a stacked or aligned combination as described above, characterized in that each container of said combination is centered in the direction of the stabilizing means of the adjacent container.

Furthermore, according to a complementary feature, on the one hand the holding means at the lid of a container and the complementary holding means at the receptacle of an adjacent container of the combination, and on the other hand the holding means at a container stabilizing means and a corresponding Complementary retaining means adjacent to the container receptacle cooperate with each other by crimping when they are in contact.

For said reasons, the resulting assembly assumes the general shape of a truncated cone or a truncated pyramid, both truncated by a longitudinal plane, the stabilizing means being longitudinally aligned on one side of said longitudinal section.

It can also be obtained that in said combination, for each cover top provided with at least two stabilizing means and each receptacle base provided with at least two stabilizing means, the respective perimeters of said top and said base At least a portion of - said portion is between two stabilizing means, lies in the same plane or is flush with the same plane.

Similarly in the combination, for each cover top provided with at least two stabilizers and each receptacle base provided with at least two stabilizers, the cover side skirt and the receptacle At least a portion of the respective perimeter of the side enclosures - said portion is included between the two stabilizing means, lying in the same plane or flush with the same plane.

For example, one or both parts of the rectangular top or base - included between the two stabilizing means - may be aligned in the same plane, or flush with the same plane when said top and base are circular.

Said container according to the invention is usually produced by roto moulage. They are preferably embodied as two separate components, namely the cover and the receptacle, each of which is itself molded in one single piece from one or more materials. The material or materials of construction of the container are typically chosen among heat-weldable polyolefin materials. Preferably, the containers of the present invention are made from a single polymeric material, preferably polyethylene, which may be low density, low linear density, medium density or high density. Octane-based high-density polyethylene (PHED), with a density of 0.940 g/ ^cm3 to 0.965 g/ ^cm3 and a crystal density of 75% to 90%, constitutes a particularly preferred The material, due to its high impact strength, provides both the side body and the side skirt each with a required thickness rigidity.

Detailed ways

As shown in FIG. 1 , the top of a lid 1 of a container according to the invention occupies a circular sector in a lower plane α, said sector being a circular sector with a perimeter P and a center C.

Thus, said circular sector generally forms the top of said cover 1 , the two parts 2 and 3 of which are visible. On the other hand, Fig. 1 also shows various raised profiles, more precisely protuberances with flat tops 4 to 8 - said flat tops being parallel to said plane α with reference β Defined in the upper plane, the raised body protrudes from the top of the cover.

In addition, it can be seen that the circular edges with C as the common center - which extend along the top protrusions 4 and 5, give said protrusions a ring-like form; connecting the tops 4, 6, 8 to the the connecting walls of the part 2 of the top of the cover, and the connecting walls of the part 3 connecting the tops 5, 7, 8 to the part 3 of the same top of the cover, are perpendicular to the planes α and β; and the The diameter d of the top constitutes the axis of symmetry of the male profile assemblies referenced 4 to 8 in FIG. 1 .

Furthermore, it can be seen that longitudinally centered on said flat top 8 on said diameter d along two parallel longitudinal edges, while flat tops 6, 7 - themselves centered on said diameter d The edge formed by the circular section of point c on d follows along the longitudinal edge on both sides of the top 8 .

Thus, the visible parts 2 and 3 of the top of the cover, also the flat tops 4 to 8 and the respective connecting walls connecting them to the top of the cover together form the lateral ends of the cover 1 wall.

On the contrary, Fig. 2 shows a circular section of an upper plane marked α' at the receptacle of the container according to the invention, said section having the circumference p' and the center C' circular area. Thus, said circular sector generally defines the base of said receptacle 1', the two parts 2' and 3' of which can be observed.

Furthermore, FIG. 2 also shows various hollows, which are represented by recesses with flat bottoms 4' and 8' in a lower plane labeled β' parallel to said plane α' Defined, the recessed portion comes from the base of the receptacle.

It should also be noted that the edges along the bottom 4' and 5' are rounded with the center C'; the connecting wall connecting the flat bottom 4', 6', 8' to the part 2' of the base of said receptacle, and the connecting walls connecting the flat bottom 5', 7', 8' to the part 3' of the same base of the cover, perpendicular to the planes α' and β', while the diameter d' of the base of the receptacle Form the axis of symmetry of the hollow section components 4' to 8' in Figure 2.

Furthermore, it can be seen that said flat bottom 8' centered longitudinally on said diameter d' is bordered by two parallel longitudinal edges, while flat bottoms 6', 7' - themselves centered on said diameter d' The edge formed by the circular section of the point c' on the diameter d' extends along the longitudinal edge just on either side of the bottom 8'.

Thus, the visible parts 2' and 3' of the base of the receptacle, also the flat bottoms 4' to 8' and the connecting walls connecting them to the base together form the transverse direction of the receptacle 1'. end wall.

The mutual contrast between the convex profile at the top of the cover in Figure 1 and the hollow profile at the base of the receptacle in Figure 2 allows for an integral complementarity of the transverse walls as designed, so that the The transverse end walls of the cover are adapted to fit within the transverse walls of the base of the receptacle.

Referring to Figures 1 and 2, it can also be seen that the circular sections of the planes α and β' partially extend in the form of outer protrusions 9 and 10 (at said cover 1 ) and similarly outer protrusions 9' and 10' (at the base 1' of the receptacle).

In fact, the edges of the projections 9 and 10 on the one hand and of the projections 9 ′ and 10 ′ on the other hand are symmetrical with respect to the diameter d or the diameter d′ respectively and orthogonal to the diameter d or the diameter d respectively '' diameters start on the same side, they are bent and then tangentially joined to the circular section of plane α (the top of the cover) or the circular section of plane β' (the base of the receptacle) respectively ).

In addition, Figures 1 and 2 show that the protruding parts 9 and 10 of the cover 1 are respectively provided with posts 11 and 12, the height of which is slightly lower than that of the flat tops 4 to 8; and relatively Specifically, the protrusions 9' and 10' of the base 1' of the receptacle are equipped with sockets 11' and 12' respectively, the inner shape of which is complementary to or substantially the shape of the posts 11 and 12 Complementary to each other, the post is suitable for fitting into the socket.

It should also be pointed out that in FIG. 1 the assembly consisting of the top part of the cover 1 provided with projections 9 and 10 surrounds a side skirt 13 perpendicular to the plane α over its entire circumference.

The assembly thus forms only a single component, which is produced, for example, from high-density polyethylene, preferably by moulding.

Also, as is clearly shown in Figure 2, said receptacle 1', equipped with projections 9' and 10', also has a side enclosure 13' on its base side, the height of which is at least equal to that of said skirt. Section 13 height. Said side walls, perpendicular to plane β', closely fit the periphery of said base 2 with protrusions 9' and 10', said assembly thus constituted forming only a single component, for example using High density polyethylene is preferably made by moulding.

According to another embodiment shown in FIG. 3 , the circular cover 1 is identical to the cover in FIG. 1 . But the flat tops of the protuberances protruding from the lower plane α no longer lie in one plane, but in two different planes parallel to the plane α, namely a plane β - in which the flat tops 4, 5 and 8 are defined. , and an intermediate plane γ - in which the tops 14 and 15 are defined, the connecting walls connecting the top 8 to the tops 14, 15 are normal to the plane γ.

Similarly, Fig. 4 shows a circular receptacle 1', which is similar to the receptacle in Fig. 2, but the difference is that the hollows are not located in one plane but in two planes parallel to plane α. In different planes, namely a lower plane β' - which defines the flats 4', 5' and 8', and an intermediate plane γ' - which defines the flats 14' and 15', connecting the flats 8' to the flats The connecting walls of the bottoms 14' and 15' are normal to the plane γ'.

The same as shown in Figures 1 and 2, there is a shape complementarity between the flat top type protrusion shown in Figure 3 and the concave part with a flat bottom shown in Figure 4, so that the lateral direction of the receptacle The end walls can be adapted to the transverse end walls of the cover by fitting.

The convex profile of the top 14, 15 in the median plane γ and the corresponding hollow profile of the flat bottom 14', 15' in the median plane γ' form complementary retaining means which further Reinforcing the rigidity of the respective transverse end walls of the cover and the receptacle.

Referring to FIG. 5 , a container according to the invention can be seen, said container comprising a receptacle 1 ′ having a circular bottom and whose side walls, referenced 13 ′, can be seen; also comprising a cover 1 , which has a rounded top and is equipped with its side skirts 13 . The cover is secured to the receptacle by fitting such that the assembly is formed to define a well adapted to receive a substantially cylindrical object such as a tambourine Or a percussion instrument like a small drum.

The general configuration of the cover is similar to that shown in Figure 3, which also includes a protuberance protruding from plane α, the flat tops 4, 5 and 8 of which are defined in plane β, and Tops 14 and 15 are defined in plane γ. It can however be seen that the tops 14, 15 each have a slightly depressed region, the bottoms 16 and 17 of which lie in the same plane δ parallel to the plane α, while the top 8 also exhibits a slight The recessed area, the bottom of which is denoted by 18 is defined in a plane coincident with the plane δ, or in a different plane parallel to the plane α.

Said different elevations of the tops 8 , 14 and 15 contribute in particular to the rigidity of the lateral end walls of the cover and of the housings for the different accessories. Thus, if desired, the concave base 16, 17 can accommodate a cladding, for example a crash cladding secured by gluing.

In order to further increase the mechanical strength of the cover, it is also conceivable that most of the tops of the different profiles forming the convex body are joined at their respective transverse end wall sections by connecting walls according to a method relative to the Lines at angles less than 90 degrees are drawn away in the direction of their lower edge. The angle is usually between 5 and 50°.

Walls - which can connect the top 4, 6, 8, 14 and correspondingly 5, 7, 8, 15 to the parts 2 and 3 of the top of the cover, and walls - ensure that the top 8 is connected to This is especially true for tops 14, 15 and bottoms 16, 17.

Figure 5 also shows a flat-bottomed longitudinal groove-like rib at the cover at 19 which serves as a seat for a locking strap, and at the receptacle at 20 the same extension The groove-like ribs, while the grooves 21 to 24 themselves serve to ensure the flow of a fluid possibly covering said transverse end walls of said cover to the outside of said cover.

In order to facilitate the fluid flow and still further enhance the mechanical strength of the wall, the wall may be slightly bulged or convex in order to absorb, inter alia, the pressure caused by the weight of a stacked container.

In contrast, Fig. 6 reproduces the container shown in Fig. 5, which clearly shows the receptacle 1' of the Fig. 5 container. It can be seen that the configuration of the receptacle is similar to that in Fig. 4, since it is also provided with a hollow-shaped part, the flat bottoms 4', 5' and 8' of which are located in the plane β ', and the flat bottoms 14' and 15' are located in the plane γ'. The shown flat bottoms 14' and 15' each present a slight bulge, the top surfaces 16' of said bulges, respectively 17', are defined in the same plane δ' parallel to the plane α'.

The difference in height of the flat bottoms 14' and 15' contributes in particular to the rigidity of the transverse end walls of the receptacle.

As shown in Figures 1, 2 and correspondingly 3, 4, the outer shapes of the cover and the transverse end walls of the receptacle are complementary and adapted to engage each other.

However, when the concave bottoms 16, 17 at a container lid are provided with a coating, the flat bottoms 16', 17' are preferably omitted and integrated with the flat bottom 14' and the corresponding 15'.

Furthermore, it can be seen in FIG. 5 that the grooved portion 25' of the side wall of the receptacle, just like the grooved portion 25 of the side wall of the cover shown in FIG. 4, can be used as a support for a locking strap. department.

It will be appreciated that, due to all the exemplified features, any stacking of containers of the same configuration but different sizes can easily be made.

Figures 7 and 8 reproduce this type of stack, in which two containers 26, 27 can be seen in Figure 7, each of which is identical to the container of Figures 5 and 6, wherein A container 27 is stacked on top of another container 26; and in Figure 8, five containers 28 to 32 can be seen, each of which is identical to the container of Figures 5 and 6, where four containers are stacked on container 28.

In this type of modular combination, the sockets 11' and 12' (not shown) of the container 27 are brought into contact with the posts 11 and 12 (not shown) of the container 26 by engagement. fit, and the transverse wall of the receptacle 33 of the container 27 is brought to bear against the transverse wall of the cover 34, so that the retaining means at the receptacle 33 and the retaining device at the cover 34 The device matches. Thus, the bearing areas 2' and 3' (not shown) at the receptacle 33 are bounded by fastening between the walls of the top 4, 14 (not shown) and the respective 5, 15 (not shown).

Figure 8, on the other hand, clearly shows that the stabilizers 9, 10 and 9', 10' of the containers 28 to 32 form two separate stabilizer assemblies which are flush with the same plane. Thus, the stack can bear against a vertical wall, which is formed in said same plane, or on a horizontal wall after being rotated through 90 degrees, so that each container is stabilized by it The device, itself bears directly against said wall.

Likewise, Fig. 8 also shows that the portion 25 of the side skirt of the cover and correspondingly the portion 25' of the side skirt of the receptacle are also located in the same longitudinal plane, so that each container can be It rests directly on a support which can be inserted between the projections 9, 10 and 9', 10'.

According to a different embodiment shown in FIG. 9 , the overall rectangular cover of a container 33 reveals on the one hand circular retaining means 34 connected to stabilizing projections 35 , 36 and on the other hand. One side reveals a circular holding device 37 which is connected to the stabilizing projections 38 , 39 . On the other hand, a rectangular holding device designated by reference numeral 40 can be seen.

Furthermore, four retaining devices 41 to 44 can be seen, which are formed by tubular ends which are partially hollowed out laterally and protrude from the projections 35 , 36 , 38 , 39 .

Thus, the retaining means 34, 40, 41 and 42 can engage in complementary retaining means (not shown) on the base of the receptacle of the container 45 shown in FIG. , the holding means 37, 40, 43 and 44 can cooperate with the holding means in the base of a container receptacle by scarfing, said container is the same size as said container 33 or different in size, so that in said container 33 to form a second stack.

A schematic diagram of a double stack of said type can be seen in FIG. Different sizes of individual containers are described.

Compared with the known containers, which are used for storing and transporting items in the musical field such as percussion instruments, the container according to the invention, belonging to the same assembly, presents the undoubted advantages of simplicity, efficiency and safety, so that all The container described above provides an alternative solution to the items described above.

The container according to the invention in particular makes it possible indeed to improve the stability of a pyramid-shaped stack embodied with the container, since the longitudinal axis of the assembly is shifted towards a significantly improved concentrated stabilization and holding area.

It is thus easy to bear the modular assembly against any wall which has the fewest points of support for the stack.

This feature is particularly advantageous when in transit, such as on a truck, because the stack, which is brought against a wall of the motor vehicle and properly oriented, can exhibit less inertia due to Balancing issues, especially when the stack is subjected to vehicle acceleration or deceleration.

Likewise, luggage transport may be implemented more conveniently, since sideways motions are minimized or even eliminated, and any uncontrollable sliding will be avoided when the transporter is tilted. In fact, the center of gravity of the modular system is close to The axis of rotation of the transport device, the stack obtains stability during transport, thereby relieving the user of muscle tension and reducing the risk of physical injury.
