Description
FIELD OF THE INVENTION

The present invention is in field of packaging; in particular it relates to packaging of FMCG products.


BACKGROUND OF THE INVENTION

The concept of sachet packs for FMCG products goes back a long time. The idea originated in the Asian markets as a way of making FMCG products available and affordable to the common man.


Sachets are great options for consumers who want to use a specific product but are against the idea of buying full-size packs due to reasons such as price constraints or consumer uncertainty for first-time buyers. Sachets are also known to help in driving consumption of products that do not have high penetration levels.


Sachet packaging, normally made of a thin film of plastic and aluminum in a sandwich laminate form, has captured many of the developing and under developed market segments and allowed the low-income communities to enjoy quality products such as shampoos, toothpastes, lotions, condiments, even ready-to-eat food and drinking water, which are not viable with normal bottle and container packaging.


While the sachets have brought better quality products to low-income communities, they have also become a waste challenge. Community waste volumes are projected to grow worldwide as adoption of these sachet products increases.


Because there is no economic incentive to collect used sachets that have been improperly dumped, they are not picked up whilst the plastic bottles are since they fetch a small amount of money if collected and returned.


Thus, waste sustainability is fast becoming an issue in countries in Asia, threatening to overrun landfills and create new ones from what are otherwise beautiful landscapes and endangering the water supply by contamination.


Biodegradable and recyclable sachets are available, but these are more expensive and affect the sensitive low-product price points which is the main justification for offering the product in sachet form in the first place.


Packaging with the film of plastic and aluminium is essential for sachets especially when used for packaging liquid products in order to avoid any leakage but are not recyclable or biodegradable.


Hence, a need remains for packaging that can be easily collected after use of the product and preferably made of cheap biodegradable or recyclable materials.


The art already provides teaching for easy and efficient folding of filled blister packs.


WO 2007/067054 relates to a blister pack for objects such as tablets, pills or capsultes, comprises a plurality of accomodation units (1) which are interconnected along lines of weakness (2). Each accomodation unit(1) is provided with a piercable base sheet (5) and a cap part (4) which is fixed to the base sheet (5), an accommodation space for accommodating an object (6) being formed between the base sheet (5) and the cap part (4) of each accommodation unit (1), characterised in that the blister pack comprises a plurality of connecting parts(3), each of which is connected by way of two respective Hines of weakness (2) to at least one accommodation unit (1) in each case.


DE10044118A1 relates to blister pack for tablets (1) has additional blisters (28) between those (13) which hold the tablets and projecting beyond them. Centering blister (2) project beyond both other sets of blisters. It also relates to a stack of blister packs with an exterior wrapping.


DE1904070A1 relates to synthetic film pack wherein recesses are immediately shaped as moulds for the still fluid chocolate, and a covering layer lying on and joined to the packing and of heat-sealable material, is provided. Preferably, it is heat-sealable paper, or a transparent aroma-proof material.


It is therefore an object of the present invention is to provide a packaging which can be easily collected after use of the product.


It is another object of the present invention to provide a packaging which encourages consumers to pick it up when seen littered.


It is yet another object of the present invention to provide a packaging model which eliminates the need of using plastic and aluminium.


It is yet another object of the present invention to provide a packaging model which uses recyclable and/or biodegradable material for packaging.


Surprisingly, it is found that a chain of emptied blister packs in the form of a compact concertina, wherein all the blisters (5) are of the same shape in a chain (1) such that the repeating units of the blister chain are linked in such a way that their cavities fit into each other when stacking in an alternating way, provide for compact waste collection.
