Definitions

• a container for prod c-fc with less packaging material is provided.
• the present invention relates to the field of the packaging of flowable products such as liquids or pasty products , particularly that of containers intended to contain beverages and more especially mineral water.
• One topic in the packaging area, especially for water is to reduce the weight of the plastic material used, and more particularly to reduce the weight of the bottom of the container.
• the first danger is that said bottom is less resistant because of the fact that the bottom is really the part of the container , which is the more submitted to constraints, due to the contact of said bottom with the place where it is disposed.
• the FR Patent No. 2772720 concerns such a container, wherein the bottom is thinner.
• the objective of the present invention is to have a container for a flowable product with a bottom allowing said container to stand and which for the same volume requires less plastic than a standard container while at the same time having comparable or higher mechanical properties .
• the container has feet at the bottom, which are integral with said body.
• the presence of three feet is a good solution, but for greater volume a presence of 4 or 5 feet is preferred.
• the geometry of said feet is not critical. Preferably, these feet have a spherical geometry.
• Concerning the bottom of the container, it has preferably a non flat form.
• the bottom has a convex form, like a semi-spherical form.
• the part of the bottom between the feet has a greater thickness of that of the walls, for example around 100-200 ⁇ m.
• a container comprising a body formed by walls having in his greater section a dimension di and a neck with an internal diameter d 2 , said container being made from a semi-crystalline PET , the body of said container comprising at its bottom at least three feet spaced from each other and being integral with said body, wherein for the body, the ratio weight of the walls on weight of the bottom is comprised between 3 and 4 and wherein the ratio volume of the body of the container per gram of PET of the body is comprised between 80 and 120,
• - closing means for closing off or distributing the product from the neck, the filled container being substantially incompressible by hand when filled with the product.
• the volume of the container used according to the invention can have all type of capacity, comprised
• the container is intended to contain all type of product, like pasty, liquid, semi- liquid, granular or powdered product.
• liquid product e understand water or a still liquid beverage, particularly still mineral waters, carbonated water or a carbonated liquid beverage, particularly sparkling mineral water.
• Other -types of liquid products are also possible, like chemical products, oil, essence, perfumes, pharmaceutical products.
• food and non food products like mayonnaise, cosmetic compounds and others.
• the means of closing are either a cap, or sealed membrane.
• the caps can be used for any diameter of opening of the neck.
• the sealed membranes are preferred with smaller diameter of the neck, for example in the area of 10 mm.
• the container can support high compressions, for example by the storage and by the transportation.
• the container can support an internal pressure of the order of 5 bar. It is also possible to close the container by sealing or welding the neck, wherein a cutting object or similar is provided for the opening.
• the container has an ovoid or substantially ovoid overall shape.
• This natural shape derived from an egg represents a structure whose resistance to vertical and/or transversal loads is optimized, thus making it possible, for a given volume and a given amount of material, to achieve mechanical properties which are equivalent to or even better than the cylindrical or roughly cylindrical shapes customarily encountered in this domain.
• the container according to the invention has a three dimensional shape convenient for gripping, a spherical , substantially spherical or cylindrical overall shape.
• the geometry with symmetry of revolution is particularly easy and therefore economical to manufacture and has the advantage of allowing the container to be filled with products which can emit gaseous substances, such as carbonated beverages (sparkling waters, sodas, etc.) in particular, which are widely consumed worldwide these days.
• gaseous substances such as carbonated beverages (sparkling waters, sodas, etc.) in particular, which are widely consumed worldwide these days.
• Such a shape is therefore particularly well suited to these liquids in that the release of carbon dioxide or other gas has a tendency to deform the bodies of bottles which do not have symmetry of revolution, having a negative impact on their stability, grasp and ease of handling, appearance, etc.
• the plastic used to fo_rm the wall or walls is a se icrystalline plastic with a slow rate of crystallization, the glass transition temperature (T g ) of which is 70 °C or higher and the cristallisation temperature Tc is around 140 °C.
• T g glass transition temperature
• Tc cristallisation temperature
• small thicker areas or portions of walls may also be provided on the body of the said container, particularly in close proximity to the neck and/or the bottom , so as to reinforce these parts locally.
• Such reinforcements may in particular be useful to facilitate the filling of the said containers or to increase their stability during storage.
• the container according to the invention is characterized in that, it has a high resistance to vertical and/or transverse loads allowing good resistance to transportation.
• the amount of PET used to produce the said container is about 30 g. for resistance to a vertical load of about 65 kg. This represents a significant saving in plastic, the few 5- litre containers that are currently on the market requiring an amount of polymer which, for comparable mechanical strength, is over two times greater than the amount needed to manufacture a container according to the present invention.
• the quantity of plastic material is of the order of 3-4 g, in comparison with a bottle of the same volume, wherein the amount of plastic is of the order of at least 12 g.
• This type of container supports a ' vertical loading of more than about 100 kg. That the container supports a vertical or transverse loading means that the weight given does not deteriorate the package integrity, that is does not lead to a risk of breaking said container.
• the container according to the invention is characterized in that the neck is fitted with a closure and/or distribution means produced in the form of a distribution tap which can be . operated with one hand.
• Such distribution taps which are known per se, advantageously allow the distribution of the flowable product contained in the container to be regulated in a particularly convenient way, for example when this container is stored horizontally on the shelves of a refrigerator, the other hand holding the container into which the said flowable product is to be transferred, for example with a view to consuming it.
• the geometry of the container can also adapt more readily to that of the storage place, as opposed to the rigid cans currently available which need to observe very specified dimensions in order to be able to be stored in restricted spaces such as the internal compartments of refrigerators.
• the space, freed as a container according to the invention is emptied can also be put to use for storing objects the size or shape of which can vary, which is not the case with rigid containers in which the volume of liquid removed is systematically replaced with air. In this type of container, the volume initially occupied remains so until the empty container is removed from the refrigerator.
• Another subject of the present invention is the use of the container by way of large-capacity, at least 5-litre capacity, container intended to contain water or a still liquid beverage, particularly still mineral water.
• Another subject of the present invention is the use of the container according to the invention by way of large- capacity, at least 5-litre capacity, container intended to contain carbonated water or a carbonated liquid beverage, particularly sparkling mineral water.
• the containers of the present invention are not in any way limited to flat or sparkling mineral waters but can be intended to contain all sorts of flowable products, edible or inedible liquids of greater or lesser fluidity such as, for example, fruit juices, milk-based beverages, etc., and also sauces or condiments (ketchup, mustard, dressing, etc.) or non-food liquids (deionized water, cleaning products, detergents, etc.).
• the packaging assembly according to the invention can also contain a functional component.
• the functional component is taken from the group consisting of a fibre, plant extract, fruit extracts, vitamins and flavors.
• the assembly is pasteurised or sterilised at a temperature in excess of 60 °C.
• the different ratios S2 on SI are comprised between 1:4.5 and 1:15. 5
• the substantial incompressibility of the filled container of the invention there is no need to have reinforcing structures.
• the consequence is that it is possible to have simple shapes, which have the0 advantage of providing transparency and purity. This is particularly important for the consumer in the case of a container for drinking water.
• Another advantage of this container is that it can be emptied without air coming in and this reduces the risk of contamination or odours-5 entering the product that may cause taste changes or degradation.
• Fig. 1 is a lateral perspective view of the container according to the invention
• Fig. 2 is another perspective view of the container of the invention, seen from the bottom and
• Fig. 3 is a graph comparing the invention with the state of the art.
• the container for a flowable product essentially consists of a body 1, formed by walls 2 and a bottom 3 and a neck 4.
• the body is made of a semi- . crystalline PET.
• the neck presents a screw 5 for receiving a cap (not shown) .
• the bottom 3 presents three feet 6 integral with the body.
• the volume of the container is of 1000 ml.
• the ratio weight of the walls on weight of the bottom is of 3.5 and the ratio volume of the body of the container per gram of PET is of 100. This means that for the volume of 1000 ml, there is 10 g of PET for the body (neck . excluded) .
• the thickness of the walls is around 70 ⁇ m. ⁇
• the neck has a height which is minimised and said neck .has a wall thickness of around 200 ⁇ m.
• the wall thickness is around 150 ⁇ m.
• the feet have a se i- .spherical shape.
• Concerning now the graph of figure 3 the x axis represents the volume of the container in ml and the y axis represents the ratio volume of the container in ml per g of the plastic material of said container.
• the graph 1 shows a bottle used on the market for sparkling water.
• the graph 2 shows a bottle used on the market for still water and the graph 3 shows a container according to the invention.
• This graph shows very clearly one of the specificity of the invention, which is that less plastic material is needed for conditioning the same volume of product.
• 1 g of plastic material is needed for 100 ml of product, whereas for products now on the market 1 g of plastic material is needed for only around 40 to 60 ml of product. That means that according to the invention, the need of plastic material is divided by 2.
