GLASS BELL JAR FOR THE PROTECTION AND/OR STORAGE OF FOOD

Abstract

A glass bell jar for the protection of food such as desserts, pies and the like, which is designed to be rested on a dish, also made of glass, so as to cover the food contained in the dish, includes a U-shaped structural section, made of a soft plastic material such as polypropylene or the like, fitted along the edge of the bell jar to cushion the impact between the dish and the bell jar when the latter is rested on the dish, to prevent direct contact between the two glass parts, and to guarantee better airtightness. The risk is avoided, that one or both parts from crack, with the danger that shards of glass could contaminate the food contained in it. Health risks are thus avoided, and the unpleasant sound caused by the impact between two glass parts is eliminated.

Description

This invention relates to a glass bell jar for the protection and/or storage of food such as desserts, pies and the like, which is designed to be rested on a dish, also made of glass, so as to cover the food contained in said dish, characterised in that it includes means made of a soft material designed to cover the edge of said bell jar to prevent direct contact between the two glass parts, namely the dish and the bell jar, and to guarantee better airtightness.

In particular said means consist of a U-shaped structural section, made of a plastic material such as polypropylene or the like, fitted along the edge of the bell jar to cushion the impact between the dish and the bell jar when the latter is rested on the dish, to prevent one or both parts from cracking, with the danger that shards of glass could contaminate the food contained in it.

With the invention according to the invention, health risks are thus avoided, and the unpleasant sound caused by the impact between two glass parts is eliminated.

Moreover, as the edge is made of plastic and consequently deformable, better adherence is achieved between the surface of the dish and the bell jar, and the airtightness is improved, thus improving storage of the food. Glass bell jars designed to protect food have been available on the market for years. In particular these products comprise a base, consisting of a glass dish or tray, and a glass bell jar designed to be positioned above said base to cover and preserve the food inside it.

However, said objects made according to the prior art present some drawbacks.

Firstly, due to the fragility of the glass, the base or the bell jar may crack when the jar is placed on the base without sufficient care, and in any event the impact between the two glass parts generates a sound which is always unpleasant to the human ear.

Moreover, as both the bell jar and the base are practically indeformable, small gaps remain in the contact area between them which allow air and moisture to penetrate into the bell jar, thus partly reducing its protective effect.

To eliminate said problems with the prior art, the present invention offers a glass bell jar for food storage which is designed to be positioned on a glass dish or tray, characterised in that the edge of said bell jar is covered with a soft material to cushion the impact between the two glass parts and improve the airtightness of the bell jar.

This invention will now be described in detail, by way of example but not of limitation, by reference to the annexed figures wherein:

FIG. 1 is a perspective view of the bell jar resting on a dish, according to the invention.

FIG. 2 is a perspective view of the plastic structural section.

FIG. 3 is a cross-sectional view of the plastic structural section.

FIG. 4 is a cross-sectional view of the structural section applied to the edge of the bell jar.

FIG. 1 illustrates the bell jar, indicated as 1, and dish 2.

The dish and bell jar are both made of glass.

A U-shaped structural section 4, made of plastic, such as polypropylene or the like, with walls 5 designed to adhere to the inner and outer surface of bell jar 1, is fitted to edge 3 of said bell jar.

Said walls 5 preferably have a variable thickness decreasing from the base to the ends, to guarantee better flexibility and consequently better adherence to said walls, thus facilitating the positioning and removal of the structural section from the bell jar for cleaning operations, for example.

Said U-shaped structural section is also made with walls 5 slightly converging, so that when the structural section is positioned on the edge, walls 5 are pushed slightly outwards, and the spring-back of the material can be exploited to keep said walls 5 adhering perfectly to edge 3, and prevent the structural section from becoming detached from the bell jar.

At the ends of walls 5 there are two bevels 6 which allow drops of water, such as condensation, to flow outside the structural section so that they do not end up between the edge of bell jar 3 and walls 5, with the risk of forming mould or other unhygienic compounds.

This invention consequently eliminates the problems of known objects with a solution that is both simple and effective.

Due to the presence of the edge made of soft material there is no longer any risk that the bell jar or the dish will crack, even if a more violent impact than usual is accidentally caused between the parts, and the problem of unpleasant noise typical of contact between glass parts is eliminated.

Moreover, as the edge is made of a deformable material it adheres perfectly to the surface of the dish, thus improving the airtightness of the bell jar to the benefit of storage of the food inside it.

Any modifications or variations shall be deemed to fall within the ambit of this invention.

The materials and dimensions can also vary, depending on the required use.

Claims

1) A glass bell jar for the protection and/or storage of foods such as desserts, pies and the like, designed to rest on a dish, also made of glass, so as to cover said food contained in said dish, which includes means made of a soft material designed to cover the edge of said bell jar to prevent it from coming into direct contact with the surface of the dish.

2) A glass bell jar for the protection and/or storage of foods such as desserts, pies and the like, as claimed in claim 1, wherein said means consist of a U-shaped structural section made of plastic equipped with two side walls designed to adhere to the inner and outer surface of the bell jar.

3) A glass bell jar for the protection and/or storage of foods such as desserts, pies and the like, as claimed in claim 2, wherein said structural section is made of plastic.

4) A glass bell jar for the protection and/or storage of foods such as desserts, pies and the like, as claimed in claim 3, wherein said structural section is made of polypropylene.

5) A glass bell jar for the protection and/or storage of food as claimed in claim 2, wherein the walls of the structural section have a variable thickness, decreasing from the base to the ends to guarantee greater flexibility.

6) A glass bell jar for the protection and/or storage of food as claimed in claim 5, characterised in that the side walls of the structural section converge slightly to guarantee better adherence to the edge of the bell jar.
