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
1. A tube with an application tip for liquid or pasty material, in particular an active agent formulation, having a. a tube body with an end which can be closed or has already been closed and with an outlet end which has a tube neck with an outlet opening, said tube body having a wall, b. an application tip which is elongated in the longitudinal direction of the tube, is connected to the outlet end of the tube body and has an inner channel having an inlet opening and an application opening, said application tip having a first part region of its longitudinal length adjacent the inlet opening and a second part region of its longitudinal length adjacent the outlet opening, and said application tip having a wall enclosing the inner channel, and c. a closure which is moulded onto the application opening of the application tip and closes the application opening, wherein the application tip has a gripping means which extends over only the first part region of the application tip and is configured as a widened portion of an outer cross section of the application tip, wherein the widened portion is widened in a first dimension vertical to the longitudinal direction with respect to an outer cross section in the second part region of the application tip, and wherein the first and second part region have substantially the same outer cross section in a second dimension perpendicular to the first dimension, wherein the gripping means is configured as a recessed grip comprising transverse ribs at right angle to the longitudinal direction of the application tip, and wherein a wall thickness of the application tip is greater than a wall thickness of the tube body, and wherein the closure is connected to the wall of the application tip in the second part region by way of extension pieces which protrude beyond the application opening in the direction of the tube body and via predetermined break points at the end of the extension pieces, and wherein the closure is not in direct contact with the gripping means and does not overlap the gripping means, and wherein the application tip is moulded onto the tube neck in a positively locking manner by way of welding, and wherein the material of the application tip is transparent and the material of the tube body is not transparent.
2. The tube with an application tip of claim 1, wherein the application tip is moulded onto the tube neck, with the result that the outlet opening of the tube body and the inlet opening of the inner channel of the application tip are connected to one another in a liquid-tight manner.
3. The tube with an application tip of claim 1, wherein the gripping means is configured as a recessed grip, optionally with grooves and ribs.
4. The tube with an application tip of claim 1, wherein the tube body and the application tip are produced in each case from polypropylenes (PP).
5. The tube with an application tip of 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).
6. The tube with an application tip of claim 1, wherein the wall of the tube body has a thickness that lies in the range from 0.2 mm to 0.6 mm.
7. The tube with an application tip of claim 1, wherein the wall of the application tip has a thickness that lies in the range from 0.3 mm to 1.2 mm.
8. The tube with an application tip of claim 3, wherein the wall of the application tip in the region of the recessed grip has a thickness that is higher than in the remaining part regions of the application tip and lies in the range from 0.4 mm to 1.4 mm.
9. The tube with an application tip of claim 1, wherein the length of the application tip without closure is at least 20% of the length of the tube body.
10. The tube with an application tip of claim 1, wherein the length of the application tip without closure lies in the range from 15 mm to 70 mm.
11. The tube with an application tip of claim 1, wherein the length of the tube body lies in the range from 15 mm to 70 mm.
12. The tube with an application tip of claim 1, wherein the end which can be closed or has already been closed can be closed or is closed by way of transverse sealing.
13. The tube with an application tip of claim 1, wherein the closure can be broken off by bending or by twisting.
14. The tube with an application tip of claim 1, wherein the tube with an application tip contains a single dose of pharmaceutical formulation.
15. The tube with an application tip of claim 1, wherein the channel has a diameter in the range from 0.5 mm to 0.8 mm.
16. The tube with an application tip of claim 1, wherein the length of the application tip without closure is at least 50% of the length of the tube body.
17. The tube with an application tip of claim 1, wherein the length of the application tip without closure is greater than or equal to the length of the tube body.
Description
FIGURES AND EXAMPLES
(1) One exemplary embodiment of the invention is to be explained with reference to the figures of the drawing, in which:

(3)
(4)
(5)
(6)
(7) The tube with an application tip 10 depicted in
(8) 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.
(9) 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.
