A FLEXIBLE STICK POUCH WITH RECLOSABLE FRONT SPOUT

FIELD OF THE INVENTION

The present invention relates to packaging. Specifically, the present invention relates to stick pack. More particularly the present invention relates to stick pack with re-closable spout. Particularly the present invention relates to stick pack with front spout packaging.

BACKGROUND OF THE INVENTION

Single-use plastic as a form of plastic can be used only once and then has to be thrown away or recycled. These are used for packaging that includes items intended for single use only. Single use plastic includes products made of plastic such as polythene bags, plastic drinking bottles, plastic bottle caps, food wrappers, plastic sachets, plastic wrappers, straws, stirrers and Styrofoam cups or plates, cotton-bud sticks, cutlery, plates, sticks for balloons, cups, food, beverage containers made of polystyrene and products made of oxo -degradable plastic, etc.

Plastic is harmful to the environment as it is non-biodegradable and takes many years to disintegrate. Single-use plastic slowly and gradually breaks down into smaller pieces of plastic known as micro plastics, hence the time span for decomposition of plastic bags is more i. e. it requires hundreds of years, thus resulting into contamination of soil and water. India alone generates 9.46 million tonnes of plastic waste every year, around 43% of which comprises single -use plastic.

Another drawback of the single use plastic is its impact on wildlife. The noxious chemicals used to produce plastic gets transmitted to animal tissue, and finally, enter the human food chain. Birds usually confuse shreds of plastic bags for food and end up eating the toxic debris. Fish consume thousands of tons of plastic in a year, ultimately transferring it up the food chain to marine animals.

On an average, plastic kills an estimated one million sea birds every year and affects around 700 species which get infected by ingesting plastics. India alone generates 9.46 million tonnes of plastic waste every year, around 43% of which comprises single -use plastic. Around 40% of plastic waste remains uncollected. So there is need for a reclosable stick pack packaging pack with spout for reusing it again and to save environment from the harmful effects of the single use plastic.

Stick pack is a type of flexible pack suitable for packaging of food cosmetics, industrial and pharma products. A stick pack is defined by its shape: it looks like a stick or a tube, having a long, slender configuration. Stick packs are narrow which makes it easy to pour the products in the package as required.

A known US patent application (US20100224522A1) discloses the construction of sachet three seal sachet, or stick pack, made from a laminate sheet, the sachet having a fin seal along a longitudinal axis and transverse fin seals at each end. The laminate sheet is tough enough to resist tearing unless a notch is provided with which to initiate a tear. A fold line extends across a corner of the sachet and through the fin seal, a notch extending through the sachet in a transverse seal area and perpendicular to the fold line such that when the sachet is folded a cut is revealed that allows the user to initiate a tear across the pack opening up a pouring spout for dispensing the medicinal product.

Another known US patent application (US20150144518A1) discloses a stick pack pack package comprising a foil sheet having side edges and first and second edges extending transversely between the side edges, a longitudinal sealing joint extending between the side edges to form the foil sheet into a tube, wherein the tube has a front side and a back side, and wherein the longitudinal sealing joint is on the back side, first and second transverse sealing joints sealing the first and second edges, respectively, a weakened pattern which extends over/across at least a portion of the longitudinal sealing joint, the back side of the tube, and the front side of the tube, wherein the weakened pattern enables the package to be opened along the pattern and wherein the weakened pattern includes nonlinear portions on the front side, back side, or front and back sides of the tube. Further it has an opening aid identifying a fold line that is (a) horizontal to the first and second edges or (b) at a 30° to 60° angle relative to the first and second edges, a weakened pattern at least partially exposed upon folding the package along the fold line, and wherein the package is opened by tearing along the weakened pattern.

Even another known US patent application (20170166380) discloses a stick pack includes: a top sealed portion with a top edge, a horizontal notch parallel with the top edge and passing through the stick pack, and a horizontal perforation line parallel with the top edge, a bottom edge portion with an elongated sealed portion proximate to a central compartment of the stick pack, a longitudinal seal extending from the top sealed edge to the bottom edge, and a spout formed at least partially in the top sealed portion but not extending past the top sealed edge, where the stick pack is configured to be folded along its longitudinal axis to fold the notch, where only when the notch is folded can a user easily tear the top sealed edge along the horizontal perforation line to expose the spout.

The above mentioned prior arts define the design of a single use stick pack which has tear point to tear and open, but those cannot be reused, but the present invention provides a solution for reusing the stickpack by providing a spout in the front part of the stickpack.
