State of the art

Containers are versatile and are used in particular for the storage, collection and disposal of materials or materials, wherein containers of all sizes and shapes are known. Waste containers intended for use in hospitals, veterinary clinics, medical and dental practices and medical research and development laboratories, in particular infectious wastes, are only used once or disposed of together with the wastes therein after they have been disposed of were sealed in a suitable manner. For this reason, it is necessary in these applications, vorzuhalten a correspondingly high number of new, empty containers that stackable because of space, so be reciprocally adjustable. Accordingly, on the one hand, empty containers are stacked and, on the other hand, the associated lids, which are typically supplied on a separate pallet. To the To improve space utilization in palletized transport, one always strives to optimize the geometric design of the lid accordingly. In this regard, however, care must be taken to ensure that there is a risk that the stacked lids, in particular lids lying down, warp in such a way that they can no longer be used to seal them tightly. However, this is indispensable for the application described above as a container of infectious waste.

EP 0 168 877 A1 discloses a lid of a container, the container having a bottom, a vertical axis aligned to the bottom, a circumferentially adjoining the bottom and an interior of the container enclosing jacket and an opening cross-section, which defines from a bottom of the opposite end of the shell and by means of Cover is tightly closed, has, wherein the lid is circumferentially distributed and arranged spaced apart snap hooks provided with adapted thereto also circumferentially distributed and spaced apart in a projecting from the shell of the container outwardly projecting edge flange of the container latching openings below Forming a movement of the cover in the direction of the vertical axis of the container preventing positive engagement are hooked.

US 3,448,888 discloses a lid of a container, the container having a bottom, a vertical axis aligned to the bottom, a circumferentially adjoining the bottom and an interior of the container enclosing jacket and an opening cross-section, which defines from a bottom of the opposite end of the shell and by means of Cover is tightly closed, has, wherein the lid is provided on a the interior of the container facing bottom with arranged close to the edge and distributed over the circumference of the lid, is provided in the closed state of the container in the direction of the interior of the container Stapelpatrizen, wherein the Stapelpatrizen in the direction of the vertical axis of the lid pressure forces can be transmitted.

EP 0 176 904 A2 discloses a lid of a container, the container having a bottom, a vertical axis aligned to the bottom, a circumferentially adjoining the bottom and an interior of the container enclosing jacket and an opening cross-section, which defines from a bottom of the opposite end of the shell and by means of Cover is tightly closed, has, wherein in a stacked state of two covers both on the underside of the upper lid and on the upper side of the lower lid in each case in a central region of the cover in question a contact area is formed and that via a contact of these two contact areas in Direction of the vertical axis of the lid pressure forces are transferable.

task

It is an object of the present invention, a cover of the aforementioned type such that it is characterized by a comfortable stackability and low susceptibility to warping.

solution

Based on the above-mentioned cover, this object is achieved in that in a stacked state of two covers both on the underside of the upper lid and on the upper side of the lower lid in each case in a central region of the cover in question a contact area is formed and that compressive forces can be transmitted via a contact of these two contact areas in the direction of the vertical axis of the lid and that stacking dies and stacking dies prevent movement of the lid in a direction perpendicular to a vertical axis of the lid when two identical lids are stacked one above the other.

In the prior art, the Stapelpatrizen or stack matrices are distributed near the edge over the circumference of the lid, so that for the load transfer of the own weight stacked lid substantially the lid edge is claimed. In particular, in the stack below lids therefore tend to deform. As a result of the arrangement according to the invention of a central contact region, a load transfer, which effectively counteracts a distortion of the cover, thus also takes place in a middle region of the cover. As a result, the quality of the lid is maintained and a tight closure of a container is - assuming proper handling - guaranteed. It is particularly useful if when placing the lid on a flat surface and the central contact area acts load-bearing, that is in contact with the pad. In this case, the undersides of all stacking patterns and / or matrices and of the central contact area are thus arranged in the same plane as possible.

Accordingly, it is advantageous if the interior of the container facing Stapelpatrizen or stacking matrices and located on the underside of the lid contact area have footprints that are in the same plane perpendicular to the vertical axis. For example, if a lid has four stacking dies at the bottom As well as the central contact area, the lid is located at five locations either on an underlying cover or on a substrate or floor.

Advantageously, the lid according to the invention on Stapelpatrizen on its underside, which have a T-shaped cross-section and each having a slot stacking matrices on the upper side of an underlying lid are engageable such that a free web of the T-shaped cross section of the Stapelpatrizen enters the slot of the stack matrices. This design of Stapelpatrizen and stacking matrices is characterized by a low material usage and is therefore less expensive than the known from the prior art and comparatively large stacking devices. In addition, an extremely accurate fitting stacking is possible by the inventive design of Stapelpatrizen and - matrices that counteracts a possible imbalance of a lid stack.

It may also be advantageous if the free webs of the cross-sectionally T-shaped Stapelpatrizen point away from the vertical axis of the lid and preferably at an angle of 40 ° to 50 ° to a transverse axis or a longitudinal axis of the lid.

According to one embodiment of the lid according to the invention it is provided that the contact area is formed in the central region at the top of the lid by a handle on which the lid or the container closed with the lid can be raised, wherein preferably at the bottom of the lid in the central region located contact area is formed from an underside of an emanating from the top of the lid recess, which allows grasping the handle with his hands. In this way, the handle of the lid is used as a contact area, so that a provision of a separate central contact area can be omitted. Already on the cover located elements are thus formed as a contact area.

In this regard, it is appropriate if the contact area on the underside of the upper lid and the contact area on the upper side of the lower lid are each formed elongated, wherein preferably two mutually parallel contact areas are formed on the upper side of the lower lid by edges of the handle with cooperate two correspondingly formed contact areas on the underside of the upper lid. Often, the handle has a U-shaped cross-section with two webs and a flange, the two webs are directed away from the lid surface, so that the elongated contact areas on the top of the lid are formed by the surfaces of the webs and thus run in a line.

With regard to the actual use of the lid and its provision for closing a container, it is advantageous if at least one, preferably at least two, preferably all arranged on a bottom of the lid Stapelpatrizen, preferably in a belt of cross-sectionally T-shaped Stapelpatrize, are each provided with a recess which allows a hanging of the lid in one or preferably two detent openings in the edge flange of the container or at an end portion of the jacket of the container. When providing a required container thus the associated lid can already be attached to the container, so that a subsequent search of the same is eliminated. This is particularly advantageous because it is not readily possible for reasons of hygiene to procure a required cover from the warehouse. A person filling the container would first have to dispose of his protective clothing before he can go to the warehouse. Also, it is often annoying when the lid is stored loosely next to or in the vicinity of the container, especially since he can take damage by the hustle and bustle in a hospital operation, which is especially important for the proper closing of the container snap hooks.

For hanging the lid on the container, it is sufficient if the recessed Stapelpatrizen are arranged on a narrow side of the lid. Alternatively, however, it is also possible to arrange these on a longitudinal side of the lid or circumferentially.

An advantageous development of the invention provides that the cover in mutually parallel cutting planes, each perpendicular to its vertical axis, each having the shape of a, preferably rounded, rectangle and the Stapelpatrizen and stacking matrices in the vicinity of, preferably rounded, corners of the rectangle are arranged.

Finally, it should be noted that the various features of the subclaims can be implemented individually for themselves or for a plurality of combinations in variants of the invention.

This geometry is good in the Figure 2d to recognize. If two or more lids 2 are stacked on top of each other, the web 26 of the stacking matrices 25 of an upper lid 2 engages in the corresponding slots 23 of the stack matrices 21 of a lower lid 2.

In addition, when stacking two covers 2, a contact area 28 on the upper side 19 of the lower lid 2, which is formed by two edges 29 of the U-shaped handle 14, with a contact area 30 on the bottom 24 of the upper lid 2, the is formed by a bottom 31 of the recess 18 in contact, this contact is linear. The linear contact area 30 of the bottom 31 of the recess 18 is indicated by dashed lines 32 in FIG FIG. 2b indicated.

In the belt 27 of the Stapelpatrizen 25 a recess 33 is introduced in each case on a side facing the short edges 9 of the lid 2 side, which is formed rectangular. As a result, the Stapelpatrizen 25 gain the shape of a hook, so that they can be hooked into the detent openings 11 or to the end 8 of the shell 5 of a container 1 and the container 1 can be provided in its open state with an associated lid 2. In the FIG. 2f the formation of the recess 28 is also easy to see.

In the FIGS. 3a and 3b two stacked lids 2, 2 'are shown once in a three-dimensional plan view and once in a three-dimensional bottom view. The upper cover 2 lies on the one hand with its four Stapelpatrizen 25 on the upper side 19 of the lower lid 2 ', wherein the web 26 of the Stapelpatrize 25 engages in the respective slot 23 of the stack matrices 21, but what in the Figures 3 can not be seen, since the view is hidden by the upper lid 2. In addition, the upper lid 2 is in its central region 13 with its contact portion 30 on its underside 24 on the associated contact portion 28 on the upper section 9 'of the lower lid 2', which is also in the Figures 3 can not be seen.

The contact areas 28, 28 ', 30, 30' are in the FIGS. 4a and 4b to see that show a vertical section in the longitudinal axis 16 and in the transverse axis 17 of the cover 2, 2 '. It is good to see that the contact surface 30 is formed on the underside 24 of the upper lid 2 of line-shaped surfaces on the bottom 31 of the recess 18, on the edges 29 'of the U-shaped handle 14' of the lower lid 2 '. rest, wherein the edges 29 'define the contact area 28' on the upper side 19 'of the lower lid 2'. Furthermore, go out of the FIGS. 4a and 4b the snap hooks 10 and the Stapelpatrizen 25 forth.

The FIG. 5 consists of a plan view of the lid 2, 2 'according to the invention FIG. 3a , wherein the sectional planes VI-VI and VII-VII, which in the FIGS. 6 and 7 are shown are registered.
