Description

Containers for two-component systems

The invention relates to a container according to the preamble of claim 1.

In a known container of this type (DE-G 87 06 592.4 Ul), the coupling ring 1 has a first circumferential groove 2 for receiving the bottom fold 4 of the first container 5 and a second circumferential groove 3 arranged at an axial distance from the first circumferential groove 2 for receiving the press-in lid closure 13 of the second container 14. The coupling ring 1 is preferably made of plastic and is relatively complex.

The invention is based on the object of simplifying the coupling of the container.

This object is achieved by the features of claim 1. The locking ring is removable so that

On the one hand, the two containers of the pack can be separated from each other effortlessly and, on the other hand, the previously existing safety feature of the push-in lid of the second container is removed. This push-in lid can then be removed and the contents of the second container can be removed particularly quickly and in the sense of perfect emptying. The force with which the coupling of the two containers is initially achieved by pressing them together depends on the fit between the bottom fold of the first container and the locking ring of the second container. The two interacting elements of the containers give way elastically in the radial direction when the containers are pressed together until the snap connection is established.

The fact that the locking ring, like the other components of the container, with the possible exception of any sealing compounds used, is made of metal, makes it easier to recycle the container. The bottom fold of the first container can, for example, be designed as a double fold or a triple fold, depending on the strength requirements placed on this fold connection. A triple fold is used for the transport of dangerous goods, particularly for relatively large container diameters. The snap connection is always designed in such a way that the second, lower container can be safely transported hanging from the first container when full. For this purpose, the first, upper container is usually equipped with opposite connection eyes for a carrying handle.

According to claim 2, commercially available, flanged securing bands are used as coupling rings, which are used anyway to secure the push-in lid closure.

Ol The features of claim 3 result in a particularly stable snap connection.

According to claim 4, the two containers of the pack can move axially relative to each other within limits as soon as the snap connection is established.

The features of claim 5 prevent the hull of the first container from coming into contact with the coupling ring, thereby preventing damage to the hull or, where applicable, its paintwork.

According to claim 6, a defined, stable end position of the upper container relative to the lower container is obtained.

According to claim 7, an axial play is created between the bottom fold and the coupling ring, which prevents damage to the bottom fold and/or the coupling ring, in particular during transport of the containers.

Further features and advantages of the invention are explained in more detail below using an exemplary embodiment of the invention shown in the drawings.

Oil e.g. an adhesive and the corresponding hardener.

The container 1 has a first container 2 that holds a first component, the body 5 of which can be closed by a first lid (not shown) and is provided with a bottom 4 that is folded by a bottom fold 3. The bottom fold 3 is designed as a triple fold, but could also be a double fold if the requirements for the strength of the bottom fold 3 are lower. The largest outer diameter 6 of the bottom fold 3 is also shown in Fig. 1.

The container 1 also has a second container 7 which holds the second component, e.g. the hardener. A body 8 of the second container 7 is closed in any way with a base and can be closed on the opposite side by a press-in lid 9, the core diameter 10 of which is shown. The press-in lid 9 rests in the pressed-in state according to Fig. 1 at the bottom and outside on a circumferential bead 11 of the body 8 and has a mirror 12.

A sealing compound 15 is compressed between an outer roll 13 of the body 9 and an outer roll 14 of the press-in lid 9 to improve the sealing effect of the press-in lid 9. The outer rolls 13, 14 are clamped together by a flanged, metallic securing band 16, i.e. pulled against each other in the axial direction of the container 1. This creates an overall tight and firm press-in lid closure 17.

The securing band 16 simultaneously forms a coupling ring 19, with the aid of which the containers 2, 7 of the container 1 can be coupled together. For this purpose, a

The inside diameter 18 of a radially innermost contour of the coupling ring 19 is dimensioned so much smaller than the largest outside diameter 6 of the bottom fold 3 that a snap connection can be made between the bottom fold and the coupling ring 19. The coupling ring forms a kind of introduction funnel 20 at the top and inside for the bottom fold 3, which centers the first container 2 when it is placed on the press-in lid closure 17. If pressure is then exerted on the first container 2 in the axial direction, the lower end of the first container 2 and the upper end of the second container 7 deform elastically in the radial direction until the bottom fold 3 has passed an inner end edge 21 of the coupling ring 19 downwards in Fig. 1. This moment is shown in Fig. 1 with solid lines. In this state, the lower end of the first container 2 and the upper end of the second container 7 have already sprung back radially into their initial position. The inner end edge 21 has, as it were, locked itself over the bottom fold and causes the containers 2, 7 to be locked or coupled to one another. Depending on the ratio of the diameters 6, 18, the force with which this coupling is made will be greater or smaller.

From the state shown in Fig. 1 with solid lines, the first container 2 can be lowered even further until the bottom fold 3 has reached the lowest position shown there in dash-dotted lines. In this lowest position, the bottom fold 3 rests on the level 12. The largest external diameter 6 of the bottom fold 3 is expediently chosen to be equal to or only slightly smaller than the core diameter 10 of the press-in lid, so that the first container 2 can be lowered without any significant radial play relative to the second container.

Oil can be moved in the axial direction. This ensures that the first container 2 remains securely in its lowest position on the level 12, even during transport of the container 1.

The mirror 12 can be provided with a central filling or removal opening (not shown) that can be closed with a plastic closure known per se. This means that the second container 7 with the finished press-in lid closure (17) can be delivered to the filler and filled by the latter and closed with the plastic closure. The filler then fills the first container 2, which has been separated from the second container 7 until then, and closes it with the lid (not shown in Fig. 1). The filler then couples the containers 2, 7 in the manner described above and sends them to his customers for shipment.

The fuselage 5 has a recess 23 adjacent to its bottom fold 3. As shown in Fig. 1 in dash-dotted lines, the fuselage 5 cannot come into contact with the inner end edge 21 of the coupling ring 19 even in its lowest position, in which the bottom fold 3 rests on the mirror 12. This prevents mutual damage during handling and transport.

Fig. 2 shows a top view of the securing band 16 and its inner end edge 21. The securing band 16 is laid and flanged in the usual way with an overlap area 22 around the outer rolls 13, 14. In the closed state, the securing band 16 can be relatively easily loosened, e.g. using a screwdriver, and removed from the outer rolls 13, 14. The press-in lid 9 can then be removed from the second container 7 to remove the second component.

Oil must be removed completely. Before this, the first container 2 can be pulled out of the press-in lid 9 with comparative ease.
