The outlet opening is provided at a first end of the lubricant container (1) for releasing the lubricant. The adjustable release mechanism comprises, at a second end of the lubricant container (1), an insert (5) which is rotatable relative to the lubricant container (1) for setting a release rate of the lubricant. The lubrication device (1) further comprises a protective cap (6) comprising a hard cover (7). The hard cover (7) covers the insert (5) and the second end of the lubricant container (1). The hard cover (7) has a smooth outer surface and an inner surface comprising engaging means (9) for engaging with the insert (5), such that the protective cap (6) is rotatable together with the insert. ## Claims ### Claim 1 A lubrication device (10) comprising: a lubricant container (1) for containing a lubricant, an outlet opening (2) at a first end of the lubricant container (1) for releasing the lubricant, an adjustable release mechanism (3) having, at a second end of the lubricant container (1), an insert (5) which is rotatable relative to the lubricant container (1) for setting a release rate of the lubricant, and a protective cap (6) a hard cover (7) for covering the insert (5) and the second end of the lubricant container, the hard cover (7) having a smooth outer surface and an inner surface providing engaging means (9) for engaging with the insert (5), such that the protective cap (6) is rotatable together with the insert (5). ### Claim 2 (depends on 1) The lubrication device (10) as claimed in claim 1, wherein the protective cap (6) further comprises a sealing ring (8), attached to the hard cover (7) and providing a waterproof enclosure of the lubricant container (1) by the protective cap (6). ### Claim 3 (depends on 1) The lubrication device (10) as claimed in claim 1, wherein the hard cover (7) is made of a transparent material. ### Claim 4 (depends on 1) The lubrication device (10) as claimed in claim 1, wherein a top surface of the protective cap (6) is dome shaped. ### Claim 5 (depends on 1) The lubrication device (10) as claimed in claim 1, wherein a surface of a side wall of the hard cover (7) is at least partly uneven for facilitating gripping and rotating the protective cap (6). ### Claim 6 (depends on 2) The lubrication device (10) as claimed in claim 2, wherein an outer surface of the sealing ring (8) and an outer surface of the lubricant container (1) both include a visual indicator, the visual indicators being arranged such that a rotation of the protective cap (6) relative to the lubrication container (1) results in showing the release rate set by the release mechanism (3). ### Claim 7 (depends on 1) The lubrication device (10) as claimed in claim 1, wherein the hard cover (7) is made of a hard plastic material ### Claim 8 (depends on 2) The lubrication device (10) as claimed in claim 2, wherein the sealing ring (8) is made of rubber. ### Claim 9 (depends on 1) The lubrication device (10) as claimed in claim 1, wherein the hard cover (7) and/or the sealing ring (8) is coated with a water resistant coating. ### Claim 10 A protective cap (6) for use with a lubrication device (10), the lubrication device (10) comprising: a lubricant container (1) for containing a lubricant, an outlet opening (2) at a first end of the lubricant container (1) for releasing the lubricant, an adjustable release mechanism (3) having, at a second end of the lubricant container (1), an insert (5) which is rotatable relative to the lubricant container (1) for setting a release rate of the lubricant, the protective cap (6) having a hard cover (7) for covering the insert (5) and the second end of the lubricant container (1), the hard cover (7) having a smooth outer surface and an inner surface comprising engaging means (9) for engaging with the insert (5), such that the protective cap (6) is rotatable together with the insert (5). ### Claim 11 (depends on 10) The protective cap (6) as claimed in claim 10, wherein the protective cap (6) further comprises a sealing ring (8), attached to the hard cover (7) for providing a waterproof enclosure of the lubricant container (1) by the protective cap (6). ### Claim 12 A method of covering a lubrication device (10), the lubrication device (10) comprising: a lubricant container (1) for containing a lubricant, an outlet opening (2) at a first end of the lubricant container (1) for releasing the lubricant, an adjustable release mechanism (3) having, at a second end of the lubricant container (1), an insert (5) which is rotatable relative to the lubrication container (1) for setting a release rate of the lubricant, the method comprising a step of applying a protective cap (6) for use with a lubrication device (10), the lubrication device (10) having; the protective cap (6) having a hard cover (7) for covering the insert (5) and the second end of the lubricant container (1), the hard cover (7) having a smooth outer surface and an inner surface comprising engaging means (9) for engaging with the insert (5), such that the protective cap (6) is rotatable together with the insert (5), and wherein the engaging means are engaged with the insert (5).
