Description

CONTINER BODY END WITH RELIABLE SEALING}

The present invention relates to a closure of the container body. The closure device is all located between the open body of the container body, in particular the bucket, and the edge of the cover which can be sealed in the open body and impressed into the container body. . The edge region includes a seal mounted in the edge region.

Such a closure device is described in document EP-A1 1 796 981 (Impress). The seal does not include a contact surface that is exactly parallel to the opening edge of the container body, so that the seal requires high pressure on the cover, especially when storing dangerous liquids in liquids, and is often used for the safety of the cover in the closed position. Cost is required. According to FIG. 4 and the description disclosed in document DE-A1 33 39 777 (Carnod), the open body 12 of the container body 10 (see drawings of the document) and the open body 12 A container having a seal between the edge regions 20 of the lid 11 which presses the seals in a sealed state is described, the lid 11 including the seal 22 in the edge region, and the seal 22 The body provided for operation with is bent 180 ° outwardly along the radius of curvature E _1/2 (see FIG. 3), and the bent section with the first section 33 has the container body 10. Along the outer side of the section 33 and bend outward substantially in the radial direction with respect to the vessel axis at the end of the section 33 (34) and then bend downward in the axial direction. According to document JP-A 2006 103771 (Liken), a "light weight" container with a closure device between the open body of the container body and the cover 3 arranged in a sealed state to the open body. (2) is described, and the container includes a seal 11 at the edge portion. The body of the container 2 provided to work with the seal 11 is bent 180 ° outward along the smallest possible radius of curvature and the bent section is arranged on the outer side of the container body.

It is an object of the claimed invention to construct a closure device in the edge region of the container body, in which a reliable sealing state is simply provided with variously manufactured covers, and depending on the cover, the closure device has another purpose of use. It is.

The said object is solved by the characteristic of Claim 1 or 10. The above features are included in the present invention. In addition, the manufacturing method of claim 18 solves the above object.

The smallest radius is formed at the bent position of the edge region of the container body, so that the opening edge of the container is narrowly formed, and a weak pressing force acts on the lid, and it is reliably inserted into the seal inside the edge region of the lid when closed. The surface variation of the seal, which is plunge and determined according to technical conditions in the plane toward the opening edge, can be compensated very effectively and without cost, and the reliability of the seal can be improved.

"Small" construction relates to the sheet metal material and its consistency, thickness and intrinsic properties, and possibly coating. The metal plate should not be damaged during sharp bending or bending, and should "overcome" or allow the radius of curvature. In particular, the radius coincides with the metal plate thickness (curvature is formed) so that the two metal plate thicknesses form the radial thickness of the body end and are smaller than the maximum three metal plate thicknesses and preferably form a metal plate thickness of 2.5.

Another configuration of the bent edge region of the container body according to claim 1 can be provided for further important purposes by the various edge regions of the lid without further modification.

The method makes it possible to produce an upper edge region of the container body. All the manufacturing steps of claims 2 to 9 can also be used in claim 18. The cover is made in particular.

The detailed description and advantages of the invention are provided from the dependent claims contained herein.

The claimed invention is clearly understood from the following description by numerous embodiments.

5 and 6 show the edge region R of the container body in a closed position by means of the edge region of another lid where the safety lip is used identically in the embodiment of the different lids and is similar to FIG. 1. drawing.

1 and 2 show preferred embodiments of the edge region R which can be used for various commercial covers to form a simple and reliable sealing device and which constitutes the container body 1. The container body and cover are traditionally made of metal sheet or thin metal plate.

Fig. 1 shows the edge region R for the axial section, and Fig. 2 shows the edge region with the edge region of a conventional lid in a sealed position in a sealed state. The container body 1 is bent by 180 ° with the smallest possible radius d at the upper end to form the upper opening edge 7 with the section 27. Thus, the bending radius corresponds to the metal plate thickness of the container body 1-with respect to the outer side of the bend, and the bent section 27 of the body together with the partial section 3 is completely on the outer side of the body. Are arranged in close contact. The section 27 is described as “bent whole section 27” and includes at least three partial sections (planar sections). The first bend 7 is shown in FIG. 1A.

Another section 8, which is bent from the lower end 3a of the section 3 arranged in close contact with the outer surface of the container body 1, faces outwardly in a radial direction with respect to the axis of the container body 1. Bent, with a small slope towards the bottom. The partial section 8 of the bent section 27 forms an opening plane 8a that facilitates the opening of the container, the function and advantages of which opening plane 8a has more clarity using FIG. 2. Is explained.

The entire section 27 bent at the radially outer end 8b of the opening plane 8a (an inclined bent plane 8) is bent downward in the axial direction. The partial section, denoted by reference numeral 11, enables the attachment of the carrying handle 12 shown and described as an embodiment in FIGS. 3 and 3A.

At the axially lower end 11a of the partial section 11, the entire section 27 is finally bent once again and bent towards the interior (plane section 13) about the axis in the radial direction with respect to the container axis. All. The edge portion 13a arranged therein is advantageously reinforced through curling. Between the last partial section 13 and section 11 of the entire section 27, the bend edge 11a forms an approximately right corner at the lower end of the section 11, the corner being-degrees. For various covers with respective safety lips 14a, 24a, 26a attached to respective edge regions as another safety means for sealing positioning of the lid as shown and described in FIGS. Can be installed.

In order to ensure the sealing positioning, the circumferencial bead 1b on the container body coincides in the cylindrical section of the lid, as shown in FIG. 2 (the closed position of the edge region of the lid and the body). It may be allowed to work with the beads 2c.

FIG. 2 also shows a preferred embodiment of the edge region R of the container body shown in FIG. 1 and the general interaction of the edge region forming a standard lid.

The standard lid 2 comprises an edge region 2a which is bent outwards, and the edge section located outside of the edge region 2a is bent 2b downwardly and inward in the radial direction. In the edge region, a seal 4 (made of sealing material) is inserted from the bottom. The narrowly defined opening edge 7 is provided such that the deviation of thickness of each given seal 4 with respect to the periphery of the container is not acceptable for the entire sealed state and the reliable sealed state is simply reached. It is simply inserted deep enough into the seal.

By the pressing process of the lid 2, the edge portion 2b of the curled lid is obtained while maintaining a small gap 9 in a state in which it is in close proximity on the planar section 8 facing outward and slightly inclined. The planar section 8 facilitates the opening of the lid and is shown as an "opening plane" 8a. For opening, for example, the flat end of the screwdriver is pushed into the gap 9 and the cover can be released from the pressurized state by the rotation of the tool. With the tool inserted into multiple positions of the periphery of the container 1 and releasing from a pressurized state, the circumferential bead 2c of the lid from the circumferential bead 1b in the body wall 1 of the container. ) Is satisfactory because it is pressed down. The partial sections 11, 13 arranged in the lower part of the planar section 8 and formed in the bent full section 27 of the container-an opening plane 8a-not shown in the figure-which act as a support for the opening tool. ) As a sufficient reinforcement of

3 shows another function of the bent section 27 of the container edge. A general carrying handle 12 may be attached to the planar section 11 which is bent downward in parallel with the vessel axis. For example, at two positions arranged in the radial direction of the third partial section 11 formed in the circumferential direction, the opening 12a shown in the plan view of FIG. 3A may be configured. The same configuration applies to another fastening means suitable for attaching the carrying handle.

4 through 6 show yet another functionality. Fig. 4 shows that the bent section 27 of the body edge is used in combination with the lid 20, and the edge region 20a of the lid bent upwards and accommodating the seal 4 is the outer side. In the end section 20b of the collar, it is preferred that it extends over the entire periphery of the lid and comprises a collar element 14 having a collar shape and having a safety lip 14a provided in the lower end region. Is fixed to the lower end of the planar section 11 of the bent entire section 27 to secure the cover axially in the closed position below the bend edge 11a. The section 14b of the collar element 14 arranged under the safety lip is pulled outward in the radial direction for easy opening of the container 1, and the fixing function portions 14a / 11a are raised.

In FIG. 5, the interaction of the modified lid with the body edge R having a function similar to that of FIG. 4 is shown. According to the cover 21, the edge region of the cover does not form an angle outward but has a hook-like portion 21a pointing upward as a fixed position for the element 24, the element 24 being It secures the seal 4a in the recess and comprises a safety lip 24a which works together with the bend edge 11a at the hook-shaped lower end of the element 24-as in the lid of FIG. 4.

The interaction of the bending edge portion 11a with the safety lip 26a is shown in FIG. 6. In FIG. 2 a lip of a safety ring 25 which is secured in the cover 2 corresponding to the cover is constructed, the safety ring overlapping the edge of the opening of the cover with the container body and the engaging section 25a, and subsequently And a safety lip 26a (or a plurality of fastening elements) around the lower end of the cover 26 arranged outside. The safety ring 25 must be assembled for the transport of dangerous goods and destroyed for the opening of the container.

From the examples of use of the closure device shown and described in various ways, the configuration of the body shown in FIG. 1 is very stable and can provide a closure device that is reliable for a wide variety of cover variants and is very good in the closure device. It becomes clear that axial fixation is enabled.
