Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in containers for freezing perishable products which solves the weakest point of a refrigeration plant.

BACKGROUND OF THE INVENTION It is known that freezing must be carried out immediately after the capture and/or slaughter of animals or the harvesting of vegetables. In any case, the product must be isolated and protected in a container that allows it to reach the consumer undamaged. However, this is not always done and the product spoils before it reaches the point of sale, as it does not receive effective protection because the container is unsuitable for its intended purpose. Jru.

Currently, rigid, flexible and composite containers are used. The most common are flexible containers comprising bags made of resin material and filled with the product, which bags are basically used for frozen vegetables. Rigid containers generally consist of cardboard boxes with thermoformed plates that contain the product, often not evenly spaced, and are primarily used for fish, shellfish, seafood, and the like.

The composite container includes a dish made of foam material with a shrinkable envelope and is primarily used for frozen meat or general frozen products.

In most of these cases, the product is frozen in its unpackaged state and exposed to a cold blast of air below -30°C or -40°C, thus dehydrating and reducing its weight by 2.5% to 3.5%. 5
%, resulting in economic losses. Moreover, freezing does not take place evenly, as long as the product is kept in disordered conditions, the action of the chilling is irregular, resulting in occasional loss of proteins and vitamins due to the inevitable formation of ice crystals.

If the product is frozen in the bag, dehydration is prevented, but condensation of internal air and accumulation of contents (e.g. in the case of vegetables)
The formation of ice crystals as a result of this is not prevented.

If the product is frozen in a dish made of foam material, the insulating effect of the material becomes apparent and the freezing occurs in an irregular manner.

In both of the above cases, freezing occurs slowly and with difficulty. This slowness results in a longer consumption of time and a greater consumption of energy, but does not prevent oxidation phenomena, weight loss and the formation of crystals, which deceive the consumer and reduce the quality of the food. Destroys nutritional substances.

Therefore, the refrigeration plant is used to store the product to be frozen.
Although it is fully organized from the point of capture and cutting to the point of sale and the consumer's home, it still has a weak point, namely the problem of containers.

No theoretical or practical means directed to overcoming the problems posed by frozen product containers are known.

While other areas of the food industry have discovered new composite materials, such as multi-layered containers used to package milk, wine or other liquids, in the field of refrigeration, advances beyond mere adaptation have It wasn't done.

SUMMARY OF THE INVENTION The present invention generally relates to improvements resulting from systematic studies of the need for freezing, refrigeration, and preservation of food products, which improvements include maintaining product moisture, preventing product oxidation, and reducing ice crystal formation. To provide a container device that supports rapid cooling without allowing the formation of.

Moreover, the improvement allows rapid packaging and stuffing of the product for freezing, transportation and storage, and the product remains undamaged until it is cooked at the consumer's home.

According to the above, the packaging device of the invention allows a minimum volume of the individual portions to be reached and a maximum volume that will always fit in a domestic refrigerator, so that the contents are always protected by the container into which they are placed. It has a modular structure.

The modular structure allows the formation of pelletizable loads, which, together with self-depositing equipment, facilitate handling, transport and storage by mechanical equipment, so that operating costs are
It will be cheaper, and the two terms of product and container will be optimized.

The container is given the required resistance, since automatic deposition means adding the load of other containers to its own load, and therefore, depending on the material to be used, depending on the refrigeration temperature to which the container is exposed. Dimensioning and reinforcement involve careful construction.

Another factor to consider is reducing the volume of transport and storage when empty. This is solved by other known empirically asymmetrical structures that allow containers to be placed inside other containers and minimize the height occupied by the containers.

All these features make the improvements described provide a container that provides a unique service, maintains a reasonable cost added to the product, and still makes the product competitive with other commonly packaged products. Configure and limit.

On the other hand, the condition to be meant by the improvement of the invention is that if the container has to be returned upon refund of money, since the real purpose is a non-returnable container for logical and hygienic reasons. , does not take into account the possibility of the retailer removing the product from its container at the time of sale. Therefore, the container is
It may later be used by the consumer in a truly practical manner. Therefore, two possibilities are considered first, namely:
The container may be converted by a cover into a sealed container for later use, and its mechanical properties are such that it can be stored in a fully loaded and easily accessible rack or close to the interior. It may be used to convert containers with complementary spacing frames into possible container configurations.

These possibilities of utilizing containers completely absorb the costs of wasted materials and prevent undesirable plans to return containers.

All of the possibilities and features outlined above point out that although the purpose of the container is primarily to protect the product, it should also facilitate, optimize and inexpensively freeze the product it contains. Therefore, it merely supplements the other 14 features that form the basis of the improvements of the present invention.

In summary, the present invention provides for free cold flow 1 to 1, including a cover or seal of the opening of the container, creating a homogeneous isothermal action around the entire container when both containers contain product.
the channel is defined between the bottom of one container and the opening of another container receiving the container, the container having a wall height that is a multiple of the rib units in the longitudinal direction. A module installation that is a multiple of the height of the wall to the subunit 1.
and the cross-section of the free cold flow tunnel is kept proportional to the volume accommodated in the container.

At the bottom of each of the units 1- or sub-units there is a spacing base which rests in a self-propelled seat which, in the working position of the unit 1- or sub-unit, is located on a supporting wing projecting from the opening of the container, The base defines coplanar cold flow tunnels between each deposition level with other cold flow tunnels of other deposition assemblies.

The above-mentioned features are therefore illustrated in the accompanying drawings, which are illustrated by way of example without limiting the scope of the invention.

With reference to the exemplary drawings, as described above, the improvement provides for a homogeneous isothermal action around the entire container on the sides and front, including the cover 5 or the seal of the opening, when both containers contain product. The goal is to limit the resulting free cold flow tunnel 3 between the bottom 1 of the container and the opening of the other container receiving the container.

The container constitutes a modular arrangement, as seen in FIGS. 5, 8 to 12, in which the units are longitudinally multiples of subunits 1 to 1 (FIG. 3,
Figure 4). The height of the walls of one unit (Fig. 5) is proportional to the volume accommodated in the container.
．． A multiple of the subunit wall height so as to maintain a cross section of 4.

For this purpose, at the bottom of each unit or subunit there is a separating base 6 which, in the working position of the unit or rib unit, is placed on a support wing 7 which projects from the opening of the container. The cold flow tunnels 4, resting in the required position and coplanar with the cold flow tunnels 1 to 1 of the other deposition assemblies, are defined between each deposition level, thus as shown in perspective view in FIG. , the deposited container forms a battery through which cold air flows, like a radiator panel, to reduce the temperature from the container and its contents.

The automatic seat of the separating base 6 consists of a protruding wall 8 which protrudes from the wing of the container and constitutes a unitary module or unitary module 1c.

Beneath the projecting wall 8 are reinforcing ribs 9 that distribute the load over the entire structure and strengthen it.

The cover 5, which facilitates subsequent use in place of the container when the contents are removed from the container, has a frontage 10 opening a passage in the wall 8.

The cover conforms to the contours of the container and for this purpose the lip 1
1, thereby creating a seal.

It is also possible that the container has this cover from the beginning,
The cover thus has wings 12, the edge 13 of which has a bite skirt 1 that allows the contents to be sealed.
4 and can be bent.

As mentioned above, the lid is sealed by a lip 11 consisting of a flexible wall projecting from the cover 5 and fitting into the container, which has walls widening towards the opening as shown, while
The flexible walls of the cover converge.

Another use instead of containers is obtained by means of a separator 15 which separates the containers from each other and limits the inlet above the height of the containers.

The separator 15 consists of a frame with side and rear walls extended by gripping clips 16 to the wings of the base unit or two base subunits. The frame also comprises a housing 17 in which the separating base 6 fits.

Although FIGS. 3 and 4 show four subunits forming one unit, subunits forming half a unit are also conceivable. Therefore, the length of the unit is twice the width of the unit, so if we maintain this width and the length of each block unit is proportional to the divisor, and use this as the length of the container, we get: 11 taken as a unit
/8.

The overall height is variable in three multiple dimensions between each other.

For safety reasons at low temperatures, the container and its cover are
Made of high-density polyethylene, when the cover is removed, the sealing sheet is made from two sheets of sealing material, the first of which is made of polyethylene to facilitate welding, while the , to the second sea 1 from polyamine to form a tear-resistant cover! [Can be done.
