Abstract

The parent patent describes a mould for moulding cooking and packing food prods. made of rigid, food quality polypropylene by injection moulding or thermo-forming. The mould is closed with food quality, flexible plastic film and placed in a vacuum chamber in order to fix the plastic film in place. The improvement is that to create a vacuum within the mould cavity itself, a suction port is formed in the wall of the mould. The port is fitted with a non-return, outlet valve from the mould cavity. Pref. the valve element is housed in a pocket on the outside of the wall of the mould. The suction port communicates between the pocket and the mould cavity. The valve element is pref. made of elastomeric material. Deformation of the element opens the suction port which is reclosed as the valve element regains its original shape. When a mould is inside the vacuum chamber, a vacuum pressure can be introduced inside the mould cavity by opening of the valve.

Description

L'invention a pour objet un moule pour mettre en oeuvre le procédé pour mouler, cuire et conditionner divers produits alimentaires qui a fait l'objet d'une demande de brevet principale n" 80 21871 déposé le 7 octobre 1980. The subject of the invention is a mold for implementing the process for molding, cooking and packaging various food products which has been the subject of a main patent application No. 80 21871 filed on October 7, 1980.

Les moules décrits dans la ~ demande de brevet d'invention ci-dessus référencée doivent être fermés par un film alimentaire souple pour la mise en place de ce film, lesdits moules sont disposés dans des cloches à vide. De manière à créer directement le vide dans le moule lui-même, celui-ci peut comporter une prise de vide munie d'un moyen faisant office de soupape. The molds described in the ~ invention patent application referenced above must be closed with a flexible food film for the establishment of this film, said molds are arranged in vacuum bells. In order to create a vacuum directly in the mold itself, it can include a vacuum connection provided with a means acting as a valve.

Les dessins ci-joints donnés à titre d'exemple indicatif et non limitatif permettront aisément de comprendre l'invention. The attached drawings given by way of indicative and non-limiting example will easily make it possible to understand the invention.

Ils représentent des modes de réalisation préférés selon l'inven- tion.They represent preferred embodiments according to the invention.

La figure I est une vue partielle schématique d'un moyen faisant office de soupape tel qu'un cylindre d'étanchéité constitué dans une matière souple qui ouvre le passage par un e action mécanique qui comprime le cylindre souple. Figure I is a schematic partial view of a means acting as a valve such as a sealing cylinder made of a flexible material which opens the passage by a mechanical action which compresses the flexible cylinder.

La figure 2 est une vue partielle schématique d'un moyen faisant office de soupape tel qu'une pastille d'étanchéité disposée verticalement contre le bord latéral dudit moule et s'ouvrant du fait de l'aspiration sans action mécanique. Figure 2 is a schematic partial view of a means acting as a valve such as a sealing pad disposed vertically against the lateral edge of said mold and opening due to the suction without mechanical action.

La figure 3 est une vue partielle schématique d'un moyen faisant office de soupape tel qu'une pastille d'étanchéité munie d'un ressort. Figure 3 is a schematic partial view of a means acting as a valve such as a sealing pad provided with a spring.

Les figures 4, 5 et 6 représentent schématiquement les prises qui servent d'obturateur. Figures 4, 5 and 6 schematically show the sockets which serve as a shutter.

Dans la figure 1, le moule 1 qui est constitué d'un polypropylène rigide alimentaire fermé par injection ou thermo-formage comporte dans son fond 5 un logement cylindrique 10 qui est
muni de deux orifices 3 et 4.In FIG. 1, the mold 1 which is made of a rigid food polypropylene closed by injection or thermoforming has at its bottom 5 a cylindrical housing 10 which is
with two holes 3 and 4.

L'orifice 3 est une prise fde vide. L'orifice 4 permet le
passage de l'air qui est à l'intérieur du moule 1 vers l'orifice
3. Cet orifice 4 est disposé de manière à ce que lorsque le cylin
dre d'étanchéité 6, qui est en matière souple étanche à l'air,
est compressé mécaniquement, sa tête 7 dégage l'orifice 4 qui
permet alors le passage de l'air de l'orifice 4 vers l'orifice
3. Une cheville 8 peut être disposée par sécurité. Port 3 is an empty outlet. Port 4 allows
passage of the air which is inside the mold 1 towards the orifice
3. This orifice 4 is arranged so that when the cylin
seal 6, which is made of flexible airtight material,
is mechanically compressed, its head 7 releases the orifice 4 which
then allows the passage of air from port 4 to port
3. A pin 8 can be arranged for safety.

Dans la figure 2, le bord 9 du moule 1 comporte un logement 10 disposé dans le sens de la hauteur du moule 1. Ce logement comporte deux orifices 3 et 4 qui ont les mêmes fonctions que dans la figure 1 précédemment décrite. La pastille 11 est dans une matière étanche souple déformable, elle peut donc se déformer par une action mécanique et laisser ainsi libre toute communication entre les orifices 4 et 3. In FIG. 2, the edge 9 of the mold 1 comprises a housing 10 arranged in the direction of the height of the mold 1. This housing has two orifices 3 and 4 which have the same functions as in FIG. 1 previously described. The pad 11 is made of a deformable flexible waterproof material, it can therefore be deformed by a mechanical action and thus leave free any communication between the orifices 4 and 3.

Dans la figure 3, le bord 9 du moule 1 comporte également un logement 12 qui est à l'extérieur du moule 1. L ' obturateur est une pastille 13 qui est maintenue appliqué contre l'orifice 4 par un ressort 14. Cette soupape agit donc automatiquement dès que la prise de vide est branchée à l'orifice 3.  In Figure 3, the edge 9 of the mold 1 also includes a housing 12 which is outside the mold 1. The shutter is a pellet 13 which is kept applied against the orifice 4 by a spring 14. This valve acts therefore automatically as soon as the vacuum connection is connected to port 3.
