Abstract

The present invention discloses a folded sheet product (2) comprising a folded sheet (3) having a first set of folds (10, 12) and a blister strip (4) attached to a segment of said sheet. A stiff portion (4, 6) may be provided at a corner segment of the sheet.

Description

Folded Sheet Product
Field of the Invention
The present invention relates to folded sheet products, whether in a folded or unfolded condition.
Background of the Invention
It is known from European Patent No. EP-A-288 472 to provide a folded sheet product comprising folded sheet with a first and second set of concertina folds, which sets of folds are transverse to one another. Provision of such folded sheets with stiff portions at segments of the sheet in the region of diagonally opposite corners of the sheet provides a means of easily unfolding and refolding the sheet material .
Manufacturers of pharmaceuticals must supply product information with the products they sell, in particular with pre-packaged products that are sold without prescription. This product information is important so that the purchaser is aware of the manner in which the product should be used, the dosage, any possible side effects of taking the product and what to do in an emergency.
This type of product information is generally enclosed in the packaging of the product in the form of a leaflet. A problem associated with such products, is that consumers rarely read the product information set out on the leaflet. Also, the leaflet often remains wedged in the packaging and is disposed of with the packaging once the product has been removed therefrom. Furthermore, as a result of automated and high speed packaging processes the wrong leaflet can be supplied with a product .
Manufacturers of other products such as shampoos, moisture creams, cosmetics, instant coffee, artificial sweeteners, seeds for gardening etc, often use blister strips to distribute samples of their products for advertising purposes. A disadvantage of this arrangement is that only a limited amount of product information, if any at all, can be displayed on blister strips.
It is an aim of preferred embodiments of the present invention to overcome problems associated with the prior art, whether mentioned herein or otherwise.
Summary of the Invention
Generally, unless otherwise stated herein, the phrase "sheet" is hereby defined as a material that takes folds at which is can be unfolded without the folds disappearing and refolded. It may be paper, or a paper-like material such as plastics sheet on which books are commonly printed, or may be very thin card or any other suitable material. It is conceivable that the sheet material may be stiff card except at the folds, e.g. very thin stiff cards interconnected by paper or cloth, but this is deprecated as not allowing full realisation of the advantages of the invention.
The present invention provides a folded sheet product comprising a folded sheet having a first set of folds and a blister strip attached to a segment of said sheet. Unless otherwise stated herein, the phrase "blister strip" means a packaging arrangement comprising a cover sheet and a substrate. The cover sheet comprises one or more indentations in which a product can be contained. The substrate is attached to the cover sheet so as to cover the openings of the indentations and thereby seal the product therein. The substrate usually comprises a foil or film material that can be easily ruptured or pierced to release the product by pushing the exterior surface of the indentation inwards.

The first section 144 of the second stiff portion 143 is separated from the first stiff portion 148 by two parallel fold lines 158 and 160 (also indicated by broken lines) .
In use of the article of Figures 15, 16 and 17, a blister strip 154 is located on the first section 144 of the second stiff portion 143. The second stiff portion 143 is then assembled by being folded along fold line 156, so that the second section 146 is superimposed over the first section 144. The openings 152 of the second section 146 are arranged to receive the indentations 154 of the blister strip when the second section 146 is superimposed on the first section 144. The first section is adhered to the second section by heat-sealing techniques, thus attaching the blister strip 150 on the second stiff portion 143 and indirectly to the folded sheet 140.
The first stiff portion 148 is then folded over the first and second sections 144, 146, now together second stiff portion 143 as illustrated by arrow A in figure 17. The pair of fold lines 158,160 provide a degree of spacing between the third section 148 and the first and second sections 144, 146 to form a spine 159, so that the third section 148 lies flat over the indentations 154 when folded. The spacing of the fold lines 158, 160 corresponds to the depth of the indentations 154 and allows for the thickness of the folded sheet.
Figure 18 shows the article of figures 15-17, but the stiff portion 148 and sections 144, 146 and 148 of the stiff portion 142 are arranged differently relative to one another. An article as shown in figure 18 can have manufacturing advantages over the article of figures 15- 17, in that a narrower manufacturing conveyor can be used.
Figures 19 and 20 show an alternative embodiment of the invention, wherein the cover 170 comprises first, second and third foldably connected stiff portions 172, 173 and 175 respectively. Second stiff portion 173 is made up from first and second sections 174, 176. Third stiff portion 175 is made up from third and fourth sections 178, 180.
A folded sheet 182 is attached to the first stiff portion
172. The first 174 and third 178 sections are each suitable for receiving a respective blister strip 184 and 186 as shown in figure 20.
The second 176 and fourth 180 sections each comprise an opening 188 and 190 respectively for receiving the indentations 192 and 194 of the blister strips 174 and 178 respectively.
In use, the blister strips 184 and 186 are located on the first 174 and third 178 sections of the stiff portions
173, 175 respectively.
The stiff portion 170 is then folded about fold line 196 (indicated by broken line) to superimpose the second portion 176 onto the first portion 174. The first 176 and third 174 sections are then adhered to one another in order to attach the blister strip 184 to the stiff portion 173. The fourth section 180 is attached to the third section 178 in the same manner, by folding about fold line 198.
The first/second sections and the third/fourth sections may then be folded over the first stiff portion 172, by folding about parallel pairs of fold lines 200 and 202 respectively.
Although, figures 19 and 20 illustrate an article wherein the blister strips 184, 186 are located on the same side of the respective stiff portions 173, 175, the blister strips 184, 186 may be located on opposing surfaces of the stiff portions 173, 175. The first/second sections 174, 176 and the third/fourth sections 178, 180 may also be folded over opposing surfaces of the first stiff portion 172.
Figures 21 to 24 show a folded sheet product 209 comprising a folded sheet 210 having a first stiff portion 212 attached to a segment thereof and a second stiff portion 214 attached to another segment thereof.
The second stiff portion 214 comprises a marginal flange 216 extending therefrom and separated therefrom by fold line 218. An edge of a blister strip 220 is attached to an edge of the second stiff portion 214 by means of the marginal flange 216.
Figures 22 and 23 show a plan view of the article of Figure 21 without the blister strip 220 attached thereto. The fold line 218 is designated by the broken line in Figure 22. Figure 25 shows an article having a folded sheet 230 with a first stiff portion 232 attached to a segment thereof. First stiff portion 232 is foldably connected to second stiff portion 236 separated from each other by a spine 238 formed by two folds 240, 242.
Opposing edges of a blister strip 244 comprising a substrate 246 and a cover 248 are attached to corresponding edges of the second stiff portion 236 by means of marginal flanges 250, 252. The marginal flanges 250, 252 are extensions of the substrate 246 of the blister strip 248 and are separated from the blister strip by fold lines 254, 256.
Figure 26 shows a plan view of the blister strip 244 of Figure 26 in an unfolded condition. Flange 250 comprises a tear line 258 illustrated by a dashed line, to provide a means of releasing one end of the blister strip 244 from the stiff portion 232, 236.
Figure 27 shows an article comprising a first stiff portion 260 attached to a segment of a folded sheet 262, a second stiff portion 264 attached to another segment of the folded sheet 262, a tab 266 and a blister strip 268.
The tab 266 is folded along fold line 270. A first section is attached to the second stiff portion 264 and a second section is attached to the blister strip. 268.
Figures 28A-28F show a folded sheet product 280 according to a further embodiment of the present invention. The product 280 comprises a first stiff portion 282 foldably connected to a second stiff portion 284, foldably connected to a third stiff portion 286. Fold lines separate the respective stiff portions, with spacing spines to provide for blister pack and folded sheet thickness.
First stiff portion 282 comprises a first tear off part 288 and a second tear off part 290 forming part of first stiff portion 282, but frangibly connected by perforations 292 to leave a tongue part 294 of first stiff portion, having a tongue 296.
A double-concertina folded sheet 298 is attached to second stiff portion 284.
A blister pack 300 is attached to third stiff portion 286, which is made up from two foldably connected sections as described with reference to Figures 15-18 above. Third stiff portion 286 also includes a slot or slit 302 for receiving tongue 296.
In use, the perforated parts 288, 290 can be torn off to reveal a tongue 296 that can be used to re-seal the package in slot 302. The product can then be opened as shown.
Alternatively, perforated parts 288, 290 can be affixed (eg adhered) to third stiff portion 286 so that tongue part 294 must be separated therefrom to open the product and access the blister pack 300. This had the additional advantages of providing a tamper evident seal over the blister pack 300 and also protecting it from premature rupture .
