TUBE WITH APPLICATION TIP

Abstract

The invention relates to a tube with an application tip for liquid or pasty material, in particular pharmaceutical. The tube has a tube body with an end which can be closed or has already been closed and with an outlet end. The outlet end of the tube has a tube neck with an outlet opening. Furthermore, the tube according to the invention has an application tip which is elongated in the longitudinal direction of the tube, is connected to the outlet end of the tube, and has an inner channel which connects an inlet opening and an application opening. A closure which closes the application opening is moulded onto the application opening of the application tip. The application tip has a gripping means.

Claims

A method for producing a filled tube with an application tip, containing the steps a. forming of a tube body with an open end and an outlet end which has a tube neck with an outlet opening, b. forming of an application tip with a gripping means over its entire length or over a portion of its length and an inner channel which connects an inlet opening and an application opening, and a closure which closes the application tip, c. moulding of the application tip with the region around its inlet opening onto the tube neck, d. filling of the tube body with a liquid or pasty material via the open end, e. transverse sealing of the open end.

2. The method according to claim 1, wherein the closure is connected to the wall of the application tip on opposite sides by way of two extension pieces which protrude beyond the application opening in the direction of the tube body, via two predetermined break points at the end of the extension pieces.

3. The method according to claim 1, wherein the gripping means extends over the portion of the length of the application tip and is formed as a widened portion in one dimension of the outer cross section of the application tip with respect to the outer cross section in other portions of the application tip.

4. The method according to claim 1, wherein the gripping means extends over the portion of the length of the application tip and is formed as a widened portion in one dimension of the inner cross section of the application tip with respect to the inner cross section in other portions of the application tip.

5. The method according to claim 1, wherein the application tip is formed with the gripping means in the region of the inlet opening.

6. The method according to claim 1, wherein the gripping means is formed as a recessed grip.

7. The method according to claim 1, wherein the gripping means is formed as a recessed grip with grooves and ribs.

8. The method according to claim 1, wherein the application tip is moulded onto the tube neck in a positively locking manner by way of welding.

9. The method according to claim 1, wherein the tube body and the application tip are produced in each case from polypropylenes (PP).

10. The method according to claim 1, wherein the tube body and the application tip are produced in each case from polyethylene (PE), polyethylene terephthalate (PET), polyvinyl chloride (PVC) or polyamide (PA).

11. The method according to claim 1, wherein the wall thickness of the application tip is greater than the wall thickness of the tube body.

12. The method according to claim 1, wherein the wall thickness of the tube body lies in the range from 0.2 mm to 0.6 mm.

13. The method according to claim 1, wherein the wall thickness of the application tip lies in the range from 0.3 mm to 1.2 mm.

14. The method according to claim 1, wherein the wall thickness of the application tip in the region of a recessed grip is higher than in the remaining portions of the application tip and lies in the range from 0.4 mm to 1.4 mm.

15. The method according to claim 1, wherein the length of the application tip without the closure is at least 20% of the length of the tube body.

16. The method according to claim 15, wherein the length of the application tip without the closure is at least 50% of the length of the tube body.

17. The method according to claim 16, wherein the length of the application tip without the closure is greater than or equal to of the length of the tube body.

18. The method according to claim 1, wherein the length of the application tip without the closure lies in the range from 15 mm to 70 mm.

19. The method according to claim 1, wherein the length of the tube body lies in the range from 15 mm to 70 mm.

20. The method according to claim 1, wherein the material of the application tip is transparent.

21. The method according to claim 1, wherein the material of the tube body is not transparent.

22. The method according to claim 1, wherein the closure can be broken off by bending or by twisting.

23. The method according to claim 1, wherein the tube with an application tip is sized to contain a single dose of pharmaceutical formulation.

24. The method according to claim 1, wherein the channel has a diameter in the range from 0.5 mm to 0.8 mm.

25. The method according to claim 1, wherein the liquid or pasty material is an active agent formulation.

Description

FIGURES AND EXAMPLES

[0026] One exemplary embodiment of the invention is to be explained with reference to the figures of the drawing, in which:

[0027] FIG. 1 shows a tube with an application tip in a perspective view,

[0028] FIG. 2 shows a tube with an application tip in a side view,

[0029] FIG. 3 shows a tube with an application tip in a front view,

[0030] FIG. 4 shows a tube with an application tip from below, and

[0031] FIG. 5 shows a tube with an application tip from the top.

[0032] The tube with an application tip 10 depicted in FIGS. 1 to 5 consists of a tube body 2 in an application tip 20.

[0033] In the exemplary embodiment which is shown, the tube body 2 is closed at its end 3 by way of a transverse sealing seam 6. In order to make simple opening and application possible, the tube body 2 is provided with a long application tip 20 with a closure 24 which is easy to open and closes the application opening 30. The closure 24 can be broken off by twisting or by bending. The closure is connected to the wall of the application tip 20 by way of two extension pieces 32 which protrude beyond the application opening 30 in the direction of the tube body and via two predetermined break points 26 at the end of the extension pieces on opposite sides. The long application tip 20 serves, even in the case of regions which are difficult to access, for example in the animal fur or in body openings, to make an application of the tube contents possible without problems. The application tip 20 can be of transparent design, with the result that a discharge of the filling material can be seen. The outlet end 4 of the tube with an application tip 10 has a tube neck 5 with an outlet opening (not visible here). The tube neck 5 which is visible merely faintly through the transparent application tip 20 is indicated by a line. The application tip 20 is moulded in a positively locking manner onto the tube neck 5. In the region of the inlet opening, with which it is also moulded onto the tube neck 5, the application tip 20 has a recessed grip 22 with transverse ribs 28, the recessed grip 22 going beyond the tube neck 5.
