Abstract: 1,270,673. Wrapping articles. H. R. HELLSTROM. 18 March, 1969 [27 March, 1968; 1 May, 1968; 4 Oct., 1968], No. 14146/69. Heading B8C. A package comprises two encapsulating members joined together around an item, one of the members extending over the item under tension and the other being foldable to part the said one member for dispensing the item, and wherein the folding of the other member is about a fold line positioned such that the planes of the portions defined by the fold line have a line of intersection when in the folded position lying within the projection of the item as initially placed on the other member. The package is particularly intended to house pharmaceuticals such as tablets, but mention is also made of packaging coffee, cream, sugar, salt, nuts, bolts and jewellery such as rings. In the embodiment of Fig. 1 and Figs. 2, 3 (not shown), the tensioned member 36 may be sealed to the front or back of relatively rigid member 32 or sealed to itself at the back thereof. Member 32 may be of cardboard, possibly having a plastics coating, plastics, wood or metal and is preferably provided with a score line or other area of weakening 38. Member 36 also preferably has aline or area of weakening 46. In a modification, Fig. 2A (not shown), member 36 comprises overlapping portions (33) adhered to one another at the overlap, or unattached overlapping or abutting portions. In the embodiment of Figs. 4, 4A (not shown), an article is encapsulated either side of relatively rigid member 32 and the latter is provided with a pair of score lines (62). The modification of Fig. 2A may be applied to this embodiment. In the embodiment of Fig. 5 (not shown), article (34<SP>1</SP>) sits in a recess (64) of member (32<SP>1</SP>). The recess may extend across the width of member (32<SP>1</SP>) to provide an area of weakening. To protect the packaged article, an auxiliary rigid member (76), Figs. 6, 6A (not shown), may be provided which reduces the opening forces on the article, or the article may be completely protected by ridge members (85), Fig. 7 (not shown), integral or otherwise with the relatively rigid member or by a shaped overlay (218), Figs. 9, 9A (not shown). In the embodiment of Fig. 8 (not shown), the article comprises a cup member (92) preferably adhered to the relatively rigid member and intended to contain liquids, semi-liquids or powders. In the embodiment of Fig. 10 and Figs. 10A, 10B (not shown), the relatively rigid member 322 has strengthening ribs 326 normal to fold line 328 and the article 332 is wholly contained in a pocket 330. More than one pocket may be provided. On bending the package, distortion of a pocket may aid ejection of the article and this effect may be enhanced by merging adjacent ribs 326 with the walls of the pocket or by scoring such walls as at (342), Figs. 11, 11A (not reproduced), or by providing the pocket with a concave end wall (344), Figs. 12, 12A, 12B (not shown). In the embodiment of Figs. 13, 13A-13C (not shown), an article is contained in a pocket (484) having strengthening sections (488, 490) and the tensioned member is a sheet (497) of, for example, plastics, paper or aluminium foil, possibly provided with a line of weakening. In a modification, Fig. 14 (not shown), stiffening members (522) are provided. In the embodiment of Figs. 15, 15A, 15B (not shown), a relatively rigid member (470) comprises a blister (466) and tensioned member (532) contacts item (462). Both members may be provided with a line of weakening.
