Description

BRIEF DESCRIPTION OF THE FIGURES

[0028] The accompanying figures show, by way of example, aspects and/or embodiments of the disclosure for better understanding and illustration. In the figures:

[0029] FIG. 1 shows a first embodiment of a coated container with a biodegradable coating on the inner surface,

[0030] FIG. 2 shows a second embodiment of a coated container with a biodegradable coating on the outer surface of the container and the outer surface of the thread of the container,

[0031] FIG. 3 shows a third embodiment of a coated container with a biodegradable coating on the inside of the outer surface of the container, and

[0032] FIG. 4 shows a fourth embodiment of a coated container with a biodegradable coating on the outer surface of the thread of the container.

DETAILED DESCRIPTION

[0033] FIG. 1 shows a first embodiment of a coated container 1 with a biodegradable coating 3 on the inner surface of the container 2. The coating 3 on the inner surface of the container 2 can protect against a loss of water vapor, carbon dioxide and/or nitrogen or the like from the container into the surrounding environment, for example when product is located in the coated container 1 and is intended to be or remain shelf-stable up to the point of use. For example, the coating can comprise a biodegradable biopolymer, for example polyhydroxyalkanoate, and/or the coating can comprise wax, gel coating, sugar coating, pomace skin, orange zest, natural gut, natural stomach, collagen casing and/or rubber, or the coating can comprise microfibrillated cellulose.

[0034] FIG. 2 shows a second embodiment of a coated container 4 with a biodegradable coating 6 on the outer surface of the container 5 and the outer surface of the thread of the container 5. The coating on the outer surfaces can protect the coated container against moisture entering from the outside and/or oxygen permeating it from the surrounding environment. This can be useful, for example, if product is located in the coated container 4 and is intended to be or remain shelf-stable up to the point of use. The thread can be stabilized by said thread being coated. The biodegradable coating 6 can comprise the types already mentioned with respect to FIG. 1.

[0035] FIG. 3 shows a third embodiment of a coated container 7 with a biodegradable coating 9 on the inner surface and a coating 10 on the outer surface of the container 8. The outer surface of the thread is not coated in this instance. Since the inner surface of the container 7 is coated, barrier properties can also be guaranteed in the region of the thread. In the closed state, a lid can be applied to the thread such that the thread can be protected against outside influences, even if the outer surface of the thread itself does not have a coating. The biodegradable coating 6 can comprise the types already mentioned with respect to FIG. 1.

[0036] FIG. 4 shows a fourth embodiment of a coated container 11 with a biodegradable coating 13 on the outer surface of the thread of the container 12. The biodegradable coating 6 can comprise the types already mentioned with respect to FIG. 1.

[0037] For example, a biodegradable biopolymer can be used as a biodegradable coating 13 to reinforce the thread region. The thread region can be or comprise the region which is coated.

[0038] For example, the thread can be stabilized with a coating 13 of microfibrillated cellulose.
