Embodiment Construction

[0019] The following is a detailed description of the invention in which similar elements are Figure 1 to Figure 11 marked with similar numbers. refer to Figure 1 to Figure 2 , the plastic wrap film formed into the flexible packaging tube 10 is placed on the mandrel 20 . The flexible packaging tube 10 has a first open end 12 , a second open end 14 and a longitudinal seam 16 . The mandrel 20 has a first end 22 extending from the rotating platform 30, a second end 24 distal to the first end 22 and a length extending from the first end 22 to the second end 24, and the mandrel 20 is rotatable relative to a rotating platform 30 . The second open end 14 of the flexible packaging tube 10 extends beyond the second end 24 of the mandrel 20 to define a protruding tube portion 18 .

[0020] Figure 3 to Figure 5 Features are shown of a fan-shaped folding plate 40 with four folding blades 42 , which is rotatable about a pivot 44 in the direction of arrow 46 . As the folding plate ...

Abstract

A high speed method for closing a tubular plastic wrap may include providing the packaging film in the form of a hollow tube on a mandrel, forming a folded surface by rotating the hollow tube and mandrel, with The plates of the plurality of folding blades are counter-rotated to form a plurality of folds defining folded surfaces substantially perpendicular to the longitudinal axis of the hollow tube, each folding blade engaging a portion of the protruding tube portion toward the fold Apply heat and pressure to the surface of the tube to form the closed end, insert the tampon into the tube, and close the first end of the tube. The film material includes at least one thermoplastic surface, and the mandrel has a first end extending from the rotating platform and a second end distal to the first end. The mandrel is rotatable relative to the rotating platform on which the mandrel is mounted.

Description

technical field [0001] The present invention relates to a method of packaging tampons. Background technique [0002] Methods for closing one end of tubular containers are known. [0003] US 8221371 to McNeil-PPC Inc. discloses a wrapper with a folded bottom and a method for overwrapping a tampon. The method includes a cylindrical wrap that protrudes beyond the end of the tampon. The withdrawal end is heat sealed. The insertion end can be domed or have a flat geometry. The jaws, preferably four, contact the insertion end so that the overlap surrounds the insertion end of the tampon and is sealed together. For this, the jaw springs are mounted and heated. The folding station folds the excess overwrap. [0004] US 5,907,941 to Fuji Photo Film. Co. purports to disclose wrapping apparatus for rolls of web, preferably photographic film. A sheet is wound around the web roll. The web roll has a core connected to a holding member. A circular rack is fixed to the folding unit...
