Description

CLOSURE DEVICE FIELD OF THE INVENTION The invention relates to a closure device for closing a neck of a bag. The invention further relates to a set of closure devices. The invention further relates to a strip or sheet of flat material for closure devices. BACKGROUND OF THE INVENTION Bags are a common packaging material for goods. As an example, bakeries put their bread in bags. These bags typically need to be temporarily opened and thereafter closed for keeping the bread fresh. This type of use, not limited to bread bags, requires to close the bag every time with some closing device. Reusable closing devices are known in the art. US5832568A discloses a binding device formed in a unified manner out of a filmy and flexible material sheet; wherein, the engaging portion with the hole formed therein, the narrow winding portion which is extended from a side of said engaging portion in order to wind around the binding part of the object to be bound, and the hooking portion which is formed at the tip of said winding portion in a nearly L-shaped form in order to be inserted into and hooked to said hole. A disadvantage of the disclosed binding device is that the shape causes a spill of material in production. Furthermore, binding devices are disposed of after use as closure device causing waste. SUMMARY OF THE INVENTION An object of the invention is to overcome one or more of the disadvantages mentioned above. According to a first aspect of the invention, a closure device for closing a neck of a bag, comprising: a flat body comprising a first edge and a second edge; an opening having an opening shape and arranged in the body at the first edge for receiving and holding the neck of the bag; and a tab having a tab shape and being part of the flat body at the second edge; wherein the opening shape and the tab shape of another closure device are selected such that the opening is couplable to the tab of the other closure device. A bag may contain goods that need to be hold in the bag, such as preserved in the bag. To have some volume in the bag for holding the goods in the bag, the bag is typically closed at the end of the bag close to the opening of the bag. The location where the bag is closed or closeable may be called the neck of the bag. The closure device comprises a flat body. The flat body is typically flexible for easy arranging the neck of the bag in the closure device or taking the neck of the bag out of the closure device. The flat body further typically simplifies production as the closure device may be punched, stamped, laser-cut or die-cut. The flat body has a first edge and a second edge. The flat body further typically comprises two flat surfaces, such as a top and bottom surface. The flat body may comprise a third edge and a fourth edge for preferably forming a substantially square flat body. The closure device comprises an opening. The opening has an opening shape. The opening is arranged in the body at the first edge such that the opening is able to receive is a simple way and to hold the neck of the bag. Typically, pulled or moved in a particular direction or in a particular pattern, the neck of the bag held in the opening may be pulled from the opening in a simple way. Thereafter the bag can be opened for taking goods out. As a last step the neck of the bag may be arranged again in the same closure device for reusing the closure device for closing the neck of the bag in again a simple way or manner. The closure device comprises a tab. The tab has a tab shape. The tab is part of the flat body at the second edge. As the tab is part of the body and the body is flat, the tab typically extends in a plane, such as a 2D plane, from the body. The opening shape and the tab shape of another closure device are selected such that the opening is couplable to the tab of the other closure device. The opening, the tab, the first edge and the second edge are shaped such that when the opening of the closure device is in a coupled condition coupled with the tab of the other closure device, the first edge of the closure device is in contact with or adjacent to a second edge of the other closure device. This implies that during production, the closure devices may be created, such as punched, stamped, laser-cut or die-cut, from a strip or sheet in a coupled condition. As the first edge and the second edge of the adjacent closure devices are in contact, the shape of the opening, the tab, the first edge and the second edge are therefore such that no material needs to be removed during production between closure devices. Hence, the technical effect of the shape of the opening, the tab, the first edge and the second edge are that waste is reduced in production. Furthermore, the closure devices after being used as closure device may be coupled for making a chain or even a flat surface. The coupled closure devices may advantageously then be reused as chain or covering surface, such as a coaster, wall paper or the like. The r
