Abstract

Freezing process indicator.

It consists of a small glass ampoule that place in the packaging of the products which are going to freeze, and consisting of two separate internal cavities (1, 2) by a thin glass wall (3), the cavity (1) is filled with water, and the cavity (2) is filled with dye, in the process of product freezing, cavity water (1) will tend to expand, breaking the thin glass wall (3), which will enter contact with the dye, but it will not dissolve in the water anymore which is ice, and therefore its dissolution is impossible, it can only dissolve if the ice becomes again water, a condition that is only possible if the process of freezing (the cold chain) is broken, if it occurs, the water will be colored indicating that the chain has broken, even if the product is frozen again.

Description

Freezing process indicator.

The present invention relates to a small product freezing process indicator system food is a small glass ampoule, placed in the product packaging, thanks to which it is controlled whether the product freezing process (the freezing chain) no It has been broken since the product was frozen for the first time, and this It comes to the end consumer.

Background of the invention

The methods commonly used to be able to check if the products have broken their freezing chain, since that was frozen for the first time, are the intuitive of each client (if the box is wet or damaged, if the product contains a excessive frost, etc.).

The applicant is unaware of the existence of any system that guarantees the freezing chain of a product It has not been broken since the beginning, as described in the following invention.

Description of the invention

The present invention, object of the following Descriptive memory, is a small glass ampoule that is placed in the packaging of the products which are going to be frozen, and that It consists of two small cavities (1, 2) separated by a small glass wall (3), one of which (1) is filled with water, and the other (2) is filled with a small amount of dye.

The vial is attached to the product container since its manufacture, and is designed with the quantities just water and coloring. Once the product is introduced into the container, and the water is frozen internal of the blister will tend to dilate, and therefore will break the thin glass wall (3), which exists between it and the dye, but this will not dissolve in the water, since the water already it is ice, and therefore its dissolution is not possible.

If the freezing chain does not break during the entire cycle, the ice, will not be colored, thus guaranteeing that there has been no defrosting, now, if by any cause, the freezing chain is broken, and the ice is thawed becoming water, it is in contact with the dye will be colored, and therefore, and even when the product is freeze again, the vial will indicate that the freezing chain it has broken, since the ice is colored, indicating in this way that the product does not meet the initial characteristics.

Brief description of the drawings

For greater understanding of how much is written in this report, it is accompanied by a drawing in which Just as an example, a case study of a freezing process indicator, placed in a container of a standard product in the market.

In said drawing the cavity (1) is appreciated which is where the water is inserted, the cavity (2) which is where it is inserted the dye, and a thin glass wall (3) which is the that separates the two cavities, and is the one that breaks in case of make the first freeze.

Description of a preferred embodiment

The indicator of the freezing process is in Small glass ampoule issue with two internal cavities, (1, 2) separated by a small glass wall (3), in the cavity (1) carries a small amount of water, previously calculated, so that in case of freezing, it is delayed enough, as to be able to break the glass wall (3), and in the cavity (2) it carries a small amount of coloring powder (red) that on contact with Water dissolves by coloring it.

The indicator is inserted from your manufacturing, in the food product container, which is will proceed to freeze, before it, both cavities (1, 2) are separated by a thin wall (3) preventing the dye comes into contact with water.

In the freezing process, the thin wall (3) it will break, due to water dilation, staying in contact Direct the ice with the dye, but it will not dissolve, since that both are in solid state.

Only if the freezing chain is broken, and the ice becomes water, the dye will dissolve in the water, leaving this a reddish color, even when it freezes again the product, the ice will indicate that the freezing chain has broken, since its color will be reddish.

Claims (4)

1. Freezing process indicator, inserted in the packaging of the products that you want to freeze, It consists of a small hollow glass ampoule with two cavities internal (1, 2) separated by a thin glass wall (3). 2. Indicator of the freezing process, according to claim one, characterized in that it consists of two internal cavities, in one of which (1) a small amount of water is inserted, calculated so that in the freezing process it breaks the thin glass wall (3). 3. Freezing process indicator, according to claim one, characterized in that it consists of two internal cavities, in one of which (2) a small amount of dye is inserted, which in case of breaking the thin glass wall (3) comes into contact with water, which in case of being in a liquid state, will dissolve by coloring it. 4. Indicator of the freezing process, according to claim one, characterized in that it consists of a thin glass wall (3) that separates the two cavities (1, 2), preventing water from coming into contact with the dye, and only It breaks in the freezing process, when the water inserted in the cavity (1) has dilated the maximum in its freezing process.
