Container body injection molding process are sprayed contiguous. Such an injection-molded container can be used for packaging sensitive products. It is particularly suitable for packaging

moisture-sensitive products, for example from the field of medicine or analytics. The desiccant disposed in the receiving space can reliably bind any moisture that may occur and in this way ensures that the packaged goods are stored or transported in a dry state.

Such containers with desiccant are known. For example, DE 10 2007 016 937 A1 shows a container for storing test strips with a housing having an opening and a lid. In the housing, a movable relative to the housing inner body is taken, which are pulled by catch means when opening the lid in the direction of the opening. For attachment of the entrainment means, the lid on its inside latching tongues. Another previously known container is described in DE 10 2005 059 675 A1. The container has a closure portion which is connected via a film hinge with the cylindrically shaped container body. In a chamber which is arranged on the closure portion is

Desiccant provided. The closure portion also projects beyond the end portion of the container body in the fully opened position.

The invention sets itself the task of a container to the effect

that it can be filled very easily by machine and, moreover, that it is easy to handle.

This object is achieved with the features of claim 1. Accordingly, it is provided in a container mentioned above, that the lid and the hinge are formed and arranged on the container body, that the lid in the open position does not project beyond the end portion of the container body, wherein the lid has a sealing portion which in the closed Position of the lid in the opening of the

Container body is arranged, and wherein the sealing portion has a sealing surface which abuts in the closed position at the inner edge of the opening.

By designing the lid so that it can be brought into a position in which it does not protrude beyond the end region of the container body, the machine handling, and in particular the

machine filling of the container can be improved. It has been found that then the filling process can be carried out particularly easily and safely. In particular, the guidance of the container during delivery to the filling machine is improved. It is advantageous if the lid is pivoted in the open position relative to the closed position by 180 °. With the sealing portion of the lid can a
