Description

Container with fixed ring for transporting and storing liquid

This creation is a container with a fixed ring for transporting and storing liquids, especially a container for transporting and storing liquids. The container is simple and economical in structure and can reduce the mechanical stress on the inner container.

German Patent Publication No. DE19535707A1 discloses a disposable and reusable container. A filling nozzle is integrally formed on the upper side of the inner container, and the end of the filling nozzle protrudes outward at the upper bottom of the outer container. The filling nozzle is firmly fixed in an opening of the rigid upper bottom by a slotted clamping ring, and the opening edge of the upper bottom is firmly against the upper side of the inner container. The filling nozzle of the inner container is closed by a screw cap.

During the use of the container, the shape of the inner container may change. For example, due to the increased filling temperature and the subsequent cooling phase, negative pressure in the range of 0.05 to 0.1 bar (bar) may appear in the inner container, resulting in deformation of the inner container. Furthermore, during transportation, the upper side of the inner container will be subject to up and down movement and rocking movement in both the filled state and the empty state, resulting in considerable mechanical stress in the nozzle area. Also in the case of fixed storage in the filled state of the inner container, a mechanical stress is applied to the upper side especially in the area of the nozzle.

It can be seen that there are still many shortcomings in the above-mentioned customary methods, and they are not a good designer, and urgently need to be improved.

In view of this, the main purpose of this creation is to provide a container for transporting and storing liquids, which is simple and economical in construction and can reduce the mechanical stress on the inner container. This objective is achieved through the feature combination of claim 1, and its beneficial results are clearly stated in the subsidiary claim.

In this creation, a fixing device fixes the nozzle to the upper bottom, and the upper bottom includes an opening to surround the nozzle with play. The fixing device has a fixing ring, and the surface of the fixing ring and the lower outer ring abuts on the edge of the opening of the upper bottom, and the opening similarly surrounds the nozzle with a play. The fixing device also has a supporting member, which is arranged between the fixing ring and the outer wall of the nozzle, and is preferably clamped on the outer wall while being close to the outer wall. The preferably elastic support abuts against the edge of the opening of the fixed ring so that it can move laterally.

This creation is based on the consideration that the rigid connection between the nozzle and the upper bottom is unfavorable, because when there is a shape change or transportation movement on the inner container, the upper side of the inner container, especially on the upper side of the nozzle High mechanical stresses are generated in the area. According to this creation, the nozzle and the inner container connected to the nozzle to some extent can move itself at least laterally relative to the opening of the upper bottom and relative to the opening of the fixing ring, thereby avoiding excessive mechanical stress. At the same time, with this configuration, the nozzle is surely held in the opening of the upper bottom, so that filling and/or emptying of the inner container can be surely performed. Due to the reduction of mechanical stress, the inner container can have a reduced inherent rigidity and can be made of thin walls, which can improve economic efficiency.

The supporting member preferably rests loosely on the edge of the opening of the fixing ring, thereby also causing a relative vertical movement between the upper bottom and the upper side of the inner container. In this way, forces acting in the vertical direction, such as transportation movement, can be absorbed, and the vertical stress in the nozzle area can be reduced.

The advantageous result is characterized in that the support is formed as an elastic O-ring or an elastic disc, preferably made of rubber, which is snapped into a circumferential groove on the outer wall of the nozzle and is laterally movable The way part abuts on the upper inner ring surface of the fixed ring. Preferably, the depth of the groove is 0.4 to 0.6 times the thickness of the O-ring. In this way, on the one hand, the O-ring is reliably held in the groove and connected to the outer wall of the nozzle in a supporting manner. On the other hand, the outside of the O-ring is preferably loosely abutted against the On the edge of the opening of the fixing ring. Therefore, handling during filling and emptying becomes easier. Another advantage is that the elastic O-ring can protect the inner container from liquid penetration.

A preferred embodiment is characterized in that the fixed ring becomes a step ring with an upper ring, a middle ring and a lower ring, wherein the upper ring covers the opening in the upper bottom, and the lower ring surrounds the outer wall of the nozzle with a clearance, The middle ring is arranged in the opening of the upper bottom with a play, and the nozzle extends into the middle ring. Viewed from the vertical direction, the upper ring and the lower ring are separated by a middle ring in the form of a sleeve. In this way, the length of the nozzle can be reduced, which has advantages in reduction of mechanical stress and improved handling during filling and emptying of liquid.

It is advantageous to provide a liquid seal between the fixed ring and the edge of the opening of the upper bottom. In this way, it is possible to prevent liquid from penetrating from the outside, for example, when it rains.

An inner container 12 made of plastic, preferably polyethylene, has three nozzles 16 on the upper side 14 of the inner container for filling and/or emptying the inner container 12. The inner container 12 has a reduced inherent rigidity and is elastically deformable to a certain extent. The inner container 12 is contained in an outer container 18 made of plastic, preferably polyethylene, which is open at the top and is otherwise closed. It has a rigid lower bottom 20 resting on a tray 22. The outer container 18 can be closed with a rigid upper bottom 26 or lid. The outer container 18 has rigid sides 24, so that the outer container 18 has a high inherent rigidity and protects the inner container 12 from external influences. The container 10 is typically designed as a reusable container for transporting liquid dangerous goods. Its inner container 12 typically has a filling volume of 500 to 1000 liters. After one or several cycles of the container 10, the inner container 12 can be replaced and replaced with a new container. To this end, the upper bottom 26 on the outer container 18 is opened and the inner container 12 is removed. In the closed state of the container 10, liquid can be filled and removed through the nozzle 16.

Please refer to Fig. 2, which is a cross-sectional top view of the nozzle on the upper side of the container with a fixed ring for transporting and storing liquid, a fixing device and a two-part closure cap. The container 10 surrounds the nozzle 16 A cross-sectional top view of the area of, which is integrally formed on the upper side 14 of the inner container 12. In an opening 28 in the upper bottom 26, a fixing ring 32 is provided with a clearance, and the opening 34 of the fixing ring 32 surrounds an outer wall 38 of the nozzle 16 through the clearance 36. A circumferential groove 50 is formed in the outer wall 38, and an elastic O-ring 42, preferably made of rubber, is snapped into the circumferential groove 50. The O-ring 42 is connected to the nozzle 16 in an elastic clamping manner. Due to the play 36 on the edge of the opening 34 of the fixing ring 32, an outer part of the O-ring 42 is loosened in a laterally displaceable manner. The ground rests on the edge of the opening 34.

The depth of the groove 40 is 0.4 to 0.6 times the thickness of the O-ring 42, and the thickness of the O-ring 42 is, for example, 5 to 8 mm.

In this embodiment, the fixed ring 32 is formed as a stepped ring, the stepped ring is Z-shaped in cross section, wherein an upper ring 44 covers the opening 28 in the upper bottom 26, for example, 10 to 10 on each side 30 mm. The Z-shaped lower ring 46 surrounds the outer wall 38 of the nozzle 16 with a clearance 36, which is typically 0.5 to 1.5 mm, that is, the diameter of the opening 34 of the fixed ring 32 is 1 to 1 larger than the outer diameter of the nozzle 16 3 mm. A middle ring 45 or sleeve connects the upper ring 44 and the lower ring 46 in a rigid manner. In FIG. 2, the lower side of the lower ring 46 abuts on the upper side 14 of the inner container 12. This is not inevitably necessary, but the upper side 14 may be spaced apart from the lower ring 46. In this case, it is also possible to perform a vertical compensation movement between the upper side 14 and the rigid upper bottom 26. The thickness of each of the upper ring 44, the middle ring 45 and the lower ring 46 is in the range of 2 to 5 mm.

The nozzle 16 is closed by a screw cap 48 in the form of a cap nut or internal threaded plug. A circumferential groove 50 is formed at the upper end of the fixing ring 32.

Please refer to FIG. 4, which is a cross-sectional view of an alternative liquid seal for a container with a fixed ring created for transporting and storing liquids. The opening 28 in the upper bottom 26 forms an upward annular edge 60 . The fixing ring 32 forms a downward outer annular edge portion 62. The two edge portions 60, 62 have a distance 64 from each other according to the play 30, and interact to form a liquid seal that prevents liquid such as rainwater from entering the opening 28 in the upper bottom 26 from the outside. In the internal space between the inner container 12 and the inner container 12, the upper bottom portion 26 is first placed on the outer container 18 when assembling. Then, the fixing ring 32 is pushed above the nozzle 16. After that, the O-ring 42 is peeled off from the nozzle 16 until it snaps into the groove 40. The O-ring 42 protrudes out of the groove 40 and therefore abuts on the lower ring 46, thereby preventing the nozzle 16 from lowering downward.

Please refer to FIG. 5, which is a schematic diagram of an alternative plan of a flat fixing ring for a container with a fixing ring for the transportation and storage of liquids. There is an alternative plan of a flat fixing ring 32 whose lower side abuts against the upper bottom. 26 on the upper side, and has a clearance 36 around the spray Mouth 16. Compared with the alternatives of FIGS. 2 to 4, this simple alternative requires an increase in the length of the upwardly protruding nozzle 16. In FIGS. 2 and 3, the Z-shaped middle ring 45 connects the upper ring 44 and the lower ring 46 in the form of a sleeve, so that the length of the nozzle 16 is short, which provides the advantage of mechanical stability. As shown in FIG. 5, a distance a can be set between the lower side of the upper bottom 26 and the upper side 14 of the inner container 12, which allows vertical relative movement between the upper side 14 and the lower side of the upper bottom 26 .

As shown in Figures 2 to 4, the alternative solution of Figure 5 can add a closure cap and a liquid seal. This component is similar to the components shown in Figures 2 to 4.
