The invention relates to a method of producing a bottle-like or tube-like container, especially a tubular pouch (10), having a tubular pouch body (20) and a sealed-in end (30), such as, for example, a base, especially a stand-up base, and optionally a sealed-in top part and/or shoulder part, wherein

The invention relates to a method of producing a bottle-like or tube-like container, especially a tubular pouch (10), having a tubular pouch body (20) and a sealed-in end (30), such as, for example, a base, especially a stand-up base, and optionally a sealed-in top part and/or shoulder part, wherein at least the base (30) and, where applicable, the top part and/or the shoulder part is introduced into the tubular pouch body (20), the tubular pouch body (20) being stretched, especially expanded, at least in the region of introduction, by a predetermined amount before and/or during introduction of the base (30) and, where applicable, of the top part and/or the shoulder part. The invention relates also to a tubular pouch so produced.

1. A method of producing a container, the container comprising: a body having walls defining interior of the container; anda base sealed to the body;the method comprising:introducing the base into the body, the body being stretched or expanded, at least in a region of introduction, by a predetermined amount before and/or during introduction of the base;wherein the base comprises an edge, said edge being arranged inside the body, and folded inwards between the base and the body so as to form a reinforced peripheral rim;wherein a support-forming seal is formed between the body and a peripheral rim of the base;wherein the support-forming seal comprises a structured surface, and the structured surface comprises a grooved or fluted surface; andwherein a degree of taper of the stretched or expanded region of the body relative to an unstretched or unexpanded body is in a range of 5° to 14.4°. 2. The method according to claim 1, wherein the stretching or expanding of the body to receive the base is carried out reversibly. 3. The method according to claim 1, wherein an amount of stretching or expanding is in the range of from 100.5% to 112.0%, relative to a diameter of an unstressed body. 4. The method according to claim 1, wherein the body, prior to the stretching or expanding, is produced by lap-seal or fin-seal sealing from a film-form material, or is extruded, in a form of a tube. 5. The method according to claim 1, wherein the stretching or expanding is carried out conically. 6. The method according to claim 1, wherein the degree of taper of the stretched or expanded region of the body relative to an unstretched or unexpanded body is in the range of 8° to 12.0°. 7. The method according to claim 1, wherein the base comprises a conically shaped peripheral rim. 8. The method according to claim 7, wherein the degree of taper of the peripheral rim of the base is slightly less than a degree of taper of the stretched or expanded region of the body. 9. The method according to claim 1, wherein the base is joined to the body to form a seal-forming seal. 10. The method according to claim 9, wherein the base is joined to the pouch body to form a seal-forming seal along an inner peripheral rim of the base. 11. The method according to claim 1, wherein the container further comprises a seal-forming seal, and the seal-forming and support-forming seals are formed substantially simultaneously. 12. The method according to claim 11, wherein the seal-forming and/or support-forming seal is effected by ultrasound, heat transfer, induction and/or hot air. 13. The method according to claim 12, wherein the base is held by suction and/or electrostatically, and introduced into the body by means of a sonotrode when ultrasound sealing is used. 14. The method according to claim 1, wherein the base has a regularly shaped outline. 15. The method according to claim 14, wherein said regularly shaped outline is a polygonal, circular or oval outline. 16. The method according to claim 1, wherein the base is sealed to the body in succession, after the tubular pouch has been filled. 17. The method according to claim 1, wherein the container is a bottle-shaped or tube-shaped container. 18. The method according to claim 17, wherein the container is a tubular pouch. 19. The method according to claim 1, wherein the sealed-in base is a stand-up base. 20. The method according to claim 4, wherein the film-form material is laminate. 21. The method according to claim 4, wherein the body is extruded seamlessly.
