Description

SINGLE - DOSE SINGLE DOSE PACKAGE OR BAG CONTAINING A BIODEGRADABLE COFFEE CAPSULE OR DOSET.

DESCRIPTION

The present utility model relates to a hermetically sealed single dose packet or sachet containing a biodegradable coffee capsule or pod.

Biodegradable capsules or pods containing ground coffee, suitable for use in domestic coffee machines, are known. They are used once and then thrown in the trash with the consequent biodegradability.

The problem associated with the use of said capsules or pods is that they are packaged normally made of flexible metal material in the production, sale and storage stages both at the level of the production and distribution chain and at the same time. of the end customer. This material must be adapted to ensure the preservation of the pod so as to maintain the organoleptic properties of the coffee until its final use. The packaging is opened at the time of end use and is discarded, but since it is made of non-biodegradable material, it causes considerable non-recoverable pollution that damages the environment.

Therefore, the purpose of this utility model is to provide a hermetically sealed single-dose packet or sachet containing a biodegradable capsule or coffee pod, adapted to overcome the aforementioned disadvantages.

A utility model object is a hermetically sealed single dose packet or sachet containing a biodegradable capsule or pod containing ground coffee, characterized in that said single dose packet or sachet is made of a biodegradable material.

A particular object of this utility model is a hermetically sealed single dose packet or sachet containing a biodegradable coffee capsule or pod.

The utility model will now be described below by an exemplary embodiment (and its variants) and with reference to the accompanying drawings provided purely by way of non-limiting example, in which: FIGS. 1 and 2 illustrate exemplary embodiments of a package or bag adapted to contain a biodegradable coffee capsule or pod: FIG. 2 illustrates a package in open form because it contains a pod;

Figures 3 and 4 illustrate embodiments of a capsule or coffee pod suitable for insertion into the above-mentioned packet or bag: in Figure 3, the capsule is illustrated in two views, from above and from lateral section, while in Figure 4, the capsule is illustrated in two views from the upper side and the lower side.

The capsule or pod (Figures 3 and 4) is made entirely of biodegradable material.

For example, it can be made of bioplastic, preferably PLA (polylactic acid), but it can also be made for example of MaterBi, a material derived from corn starch.

The material is thermoformed, biodegradable and compostable. It contains ground coffee and has microperforations 1 on one or both sides allowing the liquid coffee drink to come out, after use, by inserting it into the appropriate container of the coffee machine. It may also have a microperforated disk 2 on one side or on both sides to protect the contents, to prevent the ground coffee from coming out, and to cover and close another heat-sealed microperforated disk 2.

The discs are made of PLA or filter paper and in any case made of an absolutely biodegradable and compostable material.

The capsule or pod is provided with a shape intended to be used in the appropriate container of the coffee machine, for example, in the figures, it is substantially cylindrical.

The single dose packet or sachet (FIGS. 1 and 2) is also made from a biodegradable material, preferably a flexible material.

For example, it can be made of bioplastic, preferably PLA (polylactic acid), but can also be made for example of MaterBi, a material derived from corn starch.

Therefore, the package or pouch material is also biodegradable and compostable.

The package or bag is intended to be sealed after the insertion therein of a capsule or pod as described above, to ensure that the organoleptic characteristics of the coffee are preserved over time, and it is therefore of a size to contain a pod.

In an example of a preferred variant, the biodegradable packet or bag is made from two coupled, preferably flexible films: at the outer side of the packet or bag, a film intended to give consistency and to allow printing on the whole package or the bag, and to be printed with ink of vegetable nature. In an exemplary embodiment, a film produced by the company Sidaplax films (USA) code EF45; - At the inner side of the packet or bag, a film intended to maintain the olfactory chemical-physical characteristics of the coffee, and to provide a barrier preventing light from entering the interior of the packet or bag, and a barrier to oxygen. In an exemplary embodiment, a film produced by the company Innovia Films, code NatureFlex 22 NM White. The coupling between the two films is made with vegetable resin glue.

All materials used are biodegradable, including plant dyes as well as resin for glue.

In order to avoid biodegradation of the capsule prior to end use, it is preferred, at the time of hermetic sealing, to inject an inert preserving gas into the interior of the package, for example, non-pressurized nitrogen. The package is intended to be opened for end use, as well as to allow gas to escape. As it is inert, the gas comes out into the environment without causing any pollution problem.

The biodegradable single-dose packet or sachet containing the capsule can in turn be inserted into a box containing several packages for better distribution and storage.

The benefits from the demand of this utility model are clear.

After use, the pod may be reinserted into the open single-dose package on one side, and the assembly may be disposed of as biodegradable and compostable waste. From the above description, those skilled in the art will be able to manufacture the utility model object without the need for additional construction details.
