Embodiment Construction

[0047] [47] The container of the present invention has, for example, a cylindrical container 1 of substantially circular cross-section with a bottom 12 and an upper hole into which the product to be packaged can be introduced.

[0048] [48] ​​An inner wall 13 and bottom 12 define a storage volume.

[0049] [49] The container 1 may be made of plastic such as polypropylene or of glass or metal material.

[0050] [50] As shown in FIG. 1 , the sealing device 2 can be embedded through the upper hole of the container 1 .

[0051] [51] The device 2 is shown in more detail in FIG. 2 .

[0052] [52] In fact, the structure of the base 3 constituting the lower part of the device 2 is adapted to enclose the storage volume of the container 1, as shown in the figures.

[0053] [53] As shown, the profile of the base 3 has a certain shape (circular, polygonal or other), the dimensions of which are chosen to conform to the dimensions of the inner wall 13 .

[0054] [54] In particular, a ver...

Abstract

The inventive airtight closure device (2) for a container (1) containing a product to be packed is characterised in that it comprises a base (3) whose circumference is adjustable to the internal wall of the container (1) in such a way that it is possible to bring the internal face (4) of the base (3) into contact with the product by displacing the base (3) which provided with at least one air discharging hole closable after the base (3) is mounted. A container provided with the inventive device is also disclosed. Said invention is particularly suitable for packing food products, in particular in a liquid, pasty and powder form.

Description

technical field [0001] [01] The present invention relates to a hermetic sealing device for cooperating with a container for a product to be packaged. [0002] [02] The invention also relates to a container provided with such a device. Background technique [0003] [03] The invention finds particular application in the field of food preservation of food products susceptible to contact with air, especially liquid, paste or powder products. [0004] [04] In particular, the present invention allows the packaging of jam or paste products, completely avoiding the oxidation and microbial contamination of food. [0005] [05] Especially in the field of jam, the user usually coats a layer of paraffin wax on the upper surface of the food to be preserved. [0006] [06] The paraffin layer is advantageous in that it avoids any residual gas remaining on top of the surface of the jam. [0007] [07] On the contrary, the use of such a seal is particularly annoying, after the first use, and...
