Flexible sachet having a triangular shape

Abstract

The present invention relates to a sachet (1) having a triangular shape and comprising an interior space (6) enclosed by one sheet of flexible blank material, the sheet being folded upon itself to form a front layer (2) and a rear layer (3) of the sachet (1). The front layer (2) and the rear layer (3) are joined by sealing (4) located along two edges (5) of the sachet (1) to define the interior space (6). The sachet (1) comprises a means (7) for starting opening of the sachet (1) as well as a tear strip (11) arranged between the front layer (2) and the rear layer (3) of the sachet (1) in proximity to and running at least partially along the sealing (4) at one of the two edges (5) joined by sealing (4). The shape of the sachet (1) and the arrangement of the tear strip (11) are so that the sachet (1) obtains a cone-like shape after opening so that it is easy both to hold by hand and to reach into to take out content from the sachet (1). The invention further relates to a method of manufacturing such a sachet (1). The sachet (1) may e.g. be manufactured in a chain of sachets.

Description

FIELD OF THE INVENTION[0001]The present invention concerns a flexible, triangular sachet that can be opened into a cone-like open shape and to a method of manufacturing such a sachet.BACKGROUND OF THE INVENTION[0002]Flexible packaging prefilled with a smaller amount of an eatable product is often referred to as a sachet. It comes in different shapes, but an often used one is as a rectangular bag which has the advantage of easy storage in a flat condition, but which on the other hand is not particularly well suited for easy holding by one hand and possibly sharing with others.[0003]Another often used shape is a conical packaging which is used in a number of variations. The conical shape of the wrapping or packaging is often used for eatable products that are eaten directly from the packaging while carrying it along, such as sweets, nuts, chips or freshly baked cakes, e.g. sold at market places. The packaging is typically delivered to the shop or boot as cone shaped, or it is made by ...

AI Technical Summary

Benefits of technology

The patent is for a sachet that can be easily opened and closed and has a conical shape when opened. The sachet has a tear strip along one edge that can be torn open to access the contents. The tear strip can be pre-treated with adhesive and can be sealed along one edge of the sachet before filling it with a product. This makes it easier to keep the product in place and reduces waste. The sachet can also have a partially closed interior space to hold the product in position. The technical effects of this patent are improved ease of opening and closing, conical shape, and better placement of the product.

Problems solved by technology

It comes in different shapes, but an often used one is as a rectangular bag which has the advantage of easy storage in a flat condition, but which on the other hand is not particularly well suited for easy holding by one hand and possibly sharing with others.

However, it is a disadvantage of the conical shape that the packaging has a shape from the beginning which cannot easily be transported in a flat condition without damaging it—especially if it is make from cardboard or another relatively stiff plastic or laminate material.

They are alternatively often closed by some kind of sealing in a way that makes it hard to open the sachet without ripping the sachet whereby so much damage is easily applied to the package that part of the content is dropped on the ground.
