Description

Conditioning comprising a container, A cover and a gasket.

The invention relates to the field of conditioning.

In particular, it refers to packaging designed to contain a food product, Pharmacist, cosmetic or any other product that needs a heat treatment by pasteurization or sterilization.

Conditions are known comprising a container and a lid provided with a flat gasket. The recipient it comprises a wall that delimits an internal cavity destined to receive a content, and an edge (or lip) that delimits a appropriate opening to be closed by the lid.

Depression is generated in the cavity by performing closing the lid under vacuum or causing degassing during heat treatment.

When the container is closed with the lid, the depression in the cavity implies an understanding of the flat joint between the edge of the container and the lid.

The seal ensures a tight seal of the conditioning with a view to permanently protecting the container contents

Because the board is compressed between the edge of the container and the lid, the board has a tendency to warp by defining a weatherstrip that extends in protrusion with with respect to the container and the lid.

In addition, in a classic way, the board can present a tongue that extends to the outside of the container. The tongue is intended to be grasped by a user to move the board and thus cause a rupture of the depression inside the container with a view to facilitating opening of the conditioning.

An inconvenience of this kind of conditioning is that the presence of the weatherstrip or tongue in projection with respect to the container or the lid favors a board degradation.

Another drawback of this type of conditioning is that the board can be in contact with the contents of the container and may involve contamination of the content.

For example, in the case where the content is a food product, the contact of the product with the gasket it can lead to a migration of certain components of the board towards the product. This migration can modify the organoleptic (or taste) characteristics of the product.

The document FR-A-816 301 describes a conditioning according to the preamble of claim one.

An objective of the invention is to limit the risks of contamination of the product contained in the container.

This problem is solved within the framework of the present invention thanks to a conditioning according to the claim 1.

Because the board is separated from the internal cavity, the board is not susceptible to contact with the contents of the container.

The proposed conditioning reduces the risks of contamination of the content by the board.

In Figures 1 to 4, the conditioning depicted comprises a container 100, a lid 200 and a gasket 300

The conditioning is generally symmetric of revolution around a Z axis.

The container 100 has a general shape cylindrical and is made of glass by a procedure of molding

The container 100 comprises a wall 101 which It has an internal surface 102 and an external surface 103. The internal surface 102 surrounds an internal cavity 104 intended for contain a product

The container 100 further comprises an opening 105.

The wall 101 comprises an edge 106 (or lip) which delimits the opening 105 of the container 100. The edge 106 is extends between the inner surface 102 and the outer surface 103 of the container 100.

The edge 106 comprises a surface 107 that It has a substantially flat annular shape.

The container 100 further comprises a crown 108 extending from the outer surface 103 of the wall 101 towards the outside of the container 100 in a radial plane with respect to the wall 101. The crown 108 is made of a single piece with wall 101.

Crown 108 has a general shape cylindrical and extends around wall 101. Crown 108 it comprises a support surface 109 that has a shape substantially flat and extending parallel to the surface 107 of edge 106. The bearing surface 109 extends at a distance d_ {1} from the edge 107.

Crown 108 delimits a portion 111 of the wall 101 extending between the edge 106 and the crown 108 and It has a height d_ {1}.

The crown 108 further comprises a throat 110 formed on the support surface 109. The throat 110 has a general circular shape and extends along the surface external 103.

The cover 200 is intended to close the opening 104 of container 100.

The lid 200 is made of glass and a single piece The cover 200 comprises a body 205 having a general disk shape and that is intended to clog the opening 105 of container 100.

The cover 200 further comprises a skirt inner 202 and an outer skirt 210 extending from of body 205.

The skirts 202 and 210 extend in one general direction perpendicular to the flat part 205. The skirts 202 and 210 have a general cylindrical shape and are concentric

Skirts 202 and 210 delimit a throat 206. The throat 206 comprises a bottom surface 207 that is extends between skirts 202 and 210.

The outer skirt 210 has a height d_ {2} and comprises an edge 211. The edge 211 comprises a support surface 212 having a width of approximately 4 to 5 millimeters.

The throat 110 is adapted to receive the board 300.

The seal 300 is an O-ring that presents a shore hardness between 50 and 70 shores. When the board it is not positioned on the container 100, the joint 300 has an inner diameter smaller than the outer diameter of the wall 101 in about 0.5 to 2 millimeters.

The throat 110 typically has a section equal to substantially 1/3 of the joint section 300.

To close the container 100, the cover 200 over opening 105 such that the edge 106 of the wall 101 is inserted into throat 206 between skirts 210 and 202 of the cover 200. The outer skirt 210 comes to rest on O-ring 300.

O-ring 300 is then pressed between the bearing surface 212 of the outer skirt 210 and the bearing surface 109 of crown 108.

The compression of the joint 300 can be obtained by degassing of the container 100 under a vacuum hood with a view to creating a depression in cavity 104, during a closing stage of the container or during a heat treatment of the conditioning.

During the closing of the container 100 by the lid 200, the cover 200 is guided by the skirts 210 and 202 and the edge 106 of the container 100. The edge 106 and the throat 206 allow a centering of the lid 200 on the container 100.

The dimensions d_ {1} and d_ {2} are chosen with in order to control the compression of the joint 300. The surface 107 of the edge 106 is suitable for resting against the surface 207 at the bottom of the throat 206 in order to limit the compression of the board 300.

The throat 110 allows a positioning of the gasket 300 and maintenance of gasket 300 on the container 100

Because the seal 300 is an O-ring and is held in the throat 110, the seal 300 does not form a weatherstrip when pressed between the bearing surface 212 of the skirt 210 and the bearing surface 109 of the crown
108.

The board does not bother the application on the conditioning of an inviolability control (such as a glued paper tab) that extends at the same time over the container 100 and lid 200.

In addition, crown 108 protects seal 300 against external aggressions and limits the degradation of board 300.

Otherwise, the board 300 is separated from the internal cavity 104 of the container 100 for a portion 111 of the wall 101 extending from the edge 106. The joint 300 is extends to the side of the portion 111 opposite the internal cavity 104.

The joint 300 is arranged outside the container 100 and at distance from surface 107 of the edge 106.

This allows avoiding a contact between the contents of container 100 and joint 300.

As can be seen in Figure 2, the portion 111 presents a general conical shape. The conical shape of portion 111 contributes to guiding the lid 200 during the closure of the container 100. Conical portion 111 has an angle? at the vertex between approximately 5 and 10 degrees.

Conical portion 111 allows guidance of the gasket 300 during its positioning in the throat 110.

The conical portion 111 also allows a centered of the lid 200 on the container 100 and avoids any untimely displacement of the cover 200 with respect to the 100 container in case of shock.

As can be seen in figures 3 and 4, the crown 108 comprises two notches 112 arranged in areas of crown 108 diametrically opposed. Each notch 112 It has a width of approximately 20 mm.

Each notch 112 comprises a surface flat 113 extending in a plane tangent to throat 110. The flat surface 113 of a notch 112 forms an angle ? of approximately 30 degrees with the bearing surface 109 of the crown 108.

The notches 112 extend transversely to the board 300 and are adapted so that a tool (such as a knife) can be introduced into a notch 112 to move the joint 300 with a view to allowing the opening of the conditioning. The tool can be entered in one of the notches 112, between the joint 300 and the crown 108, to lift the joint 300. Alternatively, the tool can be introduced between the joint 300 and the support surface 212 of the cover for compressing the gasket on the surface 113 of the notch 112.
