Abstract

Butterfly closure (1) - having a first shell (2) having a closure mechanism (4) actuating a closure hook (3), and - a second shell (5) having a closure edge (5) cooperating with the closure hook (3) 6), wherein the first and the second shell (2, 5) have a common longitudinal axis (L), characterized in that - the second shell (5) along the longitudinal axis (L) is formed divided.

Description

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

Such butterfly or butterfly closures are closures for transport containers and are for example from the US 5,511,834 known. Such a butterfly closure has, on the one hand, a first shell which receives a closure mechanism which actuates a closure hook. Further, a second shell is provided which receives a cooperating with the locking hook closure edge. These two shells have a common longitudinal axis.

The disadvantage of known butterfly closures is that when closing the transport container with a parting line on both sides of the parting line a butterfly closure must be provided, which increases the structural complexity and thus the cost of the transport container.

It is therefore an object of the present invention to provide a butterfly closure specified in the preamble of claim 1 way, which makes possible a reduction of construction costs for transport containers, which are provided with a parting line.

The solution of this object is achieved by the features of claim 1.

According to the invention it is achieved that instead of two butterfly closures, which are each arranged next to the parting line of the transport container to be closed, only one closure per container side is required, which can be installed directly on the parting line, since the second shell of the butterfly according to the invention Shutter is formed divided along the longitudinal axis.

The dependent claims have advantageous developments of the invention to the content.

Further details, features and advantages of the invention will become apparent from the following description of an embodiment with reference to the drawing. It shows:

1 1 is a perspective top view of an embodiment of the butterfly closure according to the invention in an exploded view of its shells,

2 one of the 1 corresponding representation of the closure in the closed state, and

3 and 4 two installation variants of the butterfly closure according to the invention on a transport container.

A synopsis of 1 and 2 illustrates that the butterfly closure according to the invention 1 a first bowl 2 and a second shell 5 having. The first shell 2 takes a shutter mechanism 4 for actuating a locking hook 3 on.

In the second shell 5 is a closing edge 6 arranged, which, as from the representation of the 2 results in the closed state of the closure 1 with the locking hook 3 interacts.

As the 1 and 2 further clarify, have the shells 2 and 5 a common longitudinal axis L.

Along this longitudinal axis L is the second shell 5 , which represents the smaller of the two bowls, in two shell parts 5A and 5B divided. Preferably, the two shell parts 5A and 5B identical, so that also a division of the locking hook 6 in hook parts 6A and 6B results.

The 3 and 4 illustrate two installation variants of the butterfly closure according to the invention on a transport container B. As the synopsis of 3 and 4 illustrates, each side of the container B is only a closure 1 required, which is arranged with its longitudinal center line L exactly on the parting line T of the container B, so that it, in contrast to the prior art, is no longer necessary, on both sides of the parting line T each have a closure 1 So to provide two closures per side of the container B.

In addition to the above written disclosure of the invention is hereby explicitly on their graphic representation in the 1 to 4 Referenced.
