Abstract

The cartridge includes a storage chamber for the reception of one or more filler materials and a neck which contains a discharge passage for each filler material. A shock absorbing element extends about the neck and is connected at one end to the neck. A closure cap is connected to the shock absorbing element or cartridge by a hinge to selectively open and close the discharge passage(s). When in the closure position over the discharge passage(s), the closure cap is recessed within and spaced from the shock absorbing element to avoid being loosened by an impact force.

Claims (23)

1. A cartridge comprising

a storage chamber for the reception of a filler material;

a neck integrally extending from said chamber in one piece and having a discharge passage for dispensing of the filler material from said storage chamber;

a shock absorbing element having a first end connected to said neck, a jacket extending from said first end in spaced circumferential relation to said neck to define an intermediate space therebetween and a second end on said jacket opposite said first end;

a closure cap for selectively opening and closing said discharge passage of said neck, said closure cap being movable between a closure position on said neck to retain the filler material in said storage chamber and an open position to allow the dispensing of the filler material from said storage chamber, said closure cap being recessed within said shock absorbing element and with said second end of said shock absorbing element projecting beyond said closure cap; and

a connection element integrally connecting said cap to at least one of said shock absorbing element and said storage chamber.

2. A cartridge in accordance with claim 1 wherein said connection element is a hinge element.

3. A cartridge in accordance with claim 1 wherein said connection element is elastic.

4. A cartridge in accordance with claim 1 wherein said connection element is connected to said neck.

5. A cartridge in accordance with claim 1 wherein said closure cap has a margin spaced circumferentially from said jacket of said shock absorbing element with said closure cap in said closure position thereof.

6. A cartridge in accordance with claim 5 wherein said margin has an outer diameter which is larger than the outer diameter of said neck.

7. A cartridge in accordance with claim 6 wherein said margin is made as a projection which extends over at least a part of the periphery of said closure cap.

8. A cartridge in accordance with claim 7 wherein said projection at least partly surrounds said neck.

9. A cartridge in accordance with claim 1 further comprising a fastening element on said shock absorbing element and a flap on said closure cap for engaging with said fastening element to hold said closure cap in said closure position.

10. A cartridge in accordance with claim 1 wherein said closure cap has a reception element receiving said neck therein with said closure cap in said closure position.

11. A cartridge in accordance with claim 1 wherein said jacket is in uninterrupted circumferential relation to said neck.

12. A cartridge comprising

at least one tubular elongated storage chamber for the reception of a filler material;

a neck integrally extending from said chamber in one piece and having a discharge passage for dispensing of the filler material from said storage chamber;

a shock absorbing element surrounding said neck and being made in one piece with said neck, said shock absorbing element having a first end connected to said neck, a jacket extending from said first end in spaced circumferential relation to said neck to define an intermediate space therebetween and a second end on said jacket opposite said first end and extending beyond said neck;

a closure cap for selectively opening and closing said discharge passage of said neck, said closure cap being movable between a closure position on said neck to retain the filler material in said storage chamber and an open position to allow the dispensing of the filler material from said storage chamber, said closure cap being recessed within said shock absorbing element; and

a connection element integrally connecting said cap to at least one of said shock absorbing element and said storage chamber.

13. A cartridge as set forth in claim 12 further comprising a pair of tubular elongated storage chambers disposed in parallel with said neck extending from and communicating with each of said pair of tubular elongated storage chambers.
