Abstract

The packaging of the invention consists in an assembly composed of a cardboard box and of a bottle made from plastic material contained in this box. It is equipped with flexible shoulders enabling the spout to be retracted inside the box or brought outside the latter, the neck of the bottle then being engaged in an opening provided in the cover of the box.

Description

The present invention relates to a packaging for liquid or pulverulent products suitable noting for food products and chemicals.

The packaging and transport of products liable to flow (in particular liquid products) has always been a delicate problem.

Although the transport of powdered products can be carried out in other ways, the invention provides an advantageous alternative.

Metal and glass containers are much less used than in the past: they are generally heavy, allow little variation in shape and are relatively expensive. Glass containers are also breakable, which is a major drawback; metal containers are easily deformed irreversibly in the event of a fall.

Also, for several decades, the use of various plastic containers has become widespread for the packaging, among other things, of liquid food products or products used in industry or everyday life.

We therefore gradually replaced all kinds of containers formerly made of glass or metal with plastic containers intended for the same types of use, these new containers allowing easier handling and handling, in particular because of the reduction in risks damaging breakage or deformation.

A number of problems specific to the use of plastics for packaging liquid products have arisen over time, some of which still exist today, and which the present invention attempts to remedy.

For reasons of economy, it is desirable that the plastic containers are as light as possible.

With this in mind, and starting from forms copied from glass or metal packaging, plastic packaging has gradually evolved into forms better suited to the characteristics of the material, these forms making it possible to optimize the resistance to vertical compression, the limit given by an invisible and non-permanent deformation of the packaging.

Most of the developed forms which have both good resistance to vertical compression and light weight, however, have a major drawback: the ratio between the volume occupied by the size of the packaging and the volume of liquid product packaged is high and in any case never reaches the optimum value of 1. In teardrop-shaped bottles, for example, this ratio is generally greater than 2. The loss of volume is therefore enormous and considerably increases the costs of packaging, handling, storage and distribution.

Because of their rigidity, most plastic containers also occupy a considerable place in the volume of household or industrial waste. It is easily understood that it is desirable that this volume be reduced as much as possible.

Extremely light plastic packaging has been on the market for a long time and, after use, occupies a particularly small volume: these are pouches or bottles made of flexible plastic, also called cartons, which are intended for packaging shampoos, softeners or food products such as milk. However, this type of packaging is rarely used because it is extremely impractical. Once opened, the pouches can neither be closed nor held vertically. You must therefore use their content in one go. In addition, as it is a thin film without external protection, the risk of leakage is considerable.

The plastic carton boxes of the milk carton type save space during transport and storage. They contain a small amount of plastic and occupy a reduced volume in the garbage after use, provided that care is taken to flatten them.

These boxes are made from a sheet of cardboard. At least one layer of polyethylene, and possibly a layer of another material such as aluminum are made integral with the cardboard sheet by lamination or other means. This results in a particularly inconvenient ecological drawback: the materials which constitute the single composite layer of the packaging are inseparable and therefore cannot be separated by simple means. They can therefore neither be selectively destroyed by incineration nor be recovered for recycling purposes. The cardboard itself, being plasticized, is made rot-proof.

The method of opening milk carton boxes is as follows: the user must lift a folded part on top of the box and folded down on the sides and cut a corner. As long as the cut is not carried out correctly, which happens frequently, there is an overflow of milk as soon as the user takes the brick in hand to pour the contents. After opening, there are no plans to be able to close this type of packaging.

For the packaging of liquid detergents, packaging has recently been developed which consists of a combination of cardboard and plastic sheets which can, in certain cases, be closed after each withdrawal of product.

We have marketed, in particular, packaging of the milk brick type described above, the opening mode of which is different: in the center of the upper wall of the box is stuck a spout consisting of an injected piece of polyethylene. The consumer must, during the first use, himself drill a hole in the wall of the packaging, through the neck, thus creating lips directed towards the interior of the box, which prevent the complete emptying of the latter. As the neck is applied to the external part of the composite film which constitutes the wall of the packaging, it is liable to detach from it in the event of impact or rough handling. As in milk cartons, any recycling of plastic or cardboard is impossible. In addition, stacking and palletizing are difficult due to the prominence of the spout.

Another type of packaging known on the market and intended for liquid detergents allows easier pouring of the product. It is a package consisting of a cardboard sheet which is given the shape of a box, in which a sheet of plastic material welded in the form of a bag is glued in many places. The upper wall of this packaging is perforated, from manufacture, in an off-center manner. A neck secured to the cardboard and the plastic sheet is placed at the location of the hole provided on the top of the box. The opening, closing and pouring of the product are relatively easy. It is nevertheless observed in practice that, in particular because of the parallelepiped shape of the box, it is also practically impossible to empty it.

Here again, the components (cardboard and plastic) are very difficult to separate, which is undesirable from an ecological point of view. In addition, this type of packaging requires the use of a large amount of glue. The stacking and palletizing problems are also not resolved.

There is a particular model of this type of packaging, in the lid of which a large opening has been provided. The neck, which is then secured only to the plastic sheet can sink into the box through this opening. From that moment, it often happens that it turns obliquely and disappears in the box, where it is then difficult to recover it. The orientation of the product jet is also not guaranteed during pouring.

There is also another particular model of this type of packaging where the neck is located in a "cut corner" of the cardboard box. In this case, the resistance of the packaging to vertical compression is reduced. The packages mentioned above are not designed to be filled by the neck. They must be manufactured and filled by complex and costly machines, which form the cardboard, apply the plastic there and immediately fill. This means in each case that the manufacturer of the packaged product will have to transport his goods in bulk to the premises where the packaging is produced or invest in machines for manufacturing and filling packaging, which entails additional costs.

The object of the invention is to provide a packaging for liquid or pulverulent products, composed of cardboard and of a small quantity of plastic material with regard to the capacity of the packaging, which allows total separation of its components which can be sorted. before being discarded, allowing selective collection and recycling of components.

An object of the invention is to provide a packaging for liquid or pulverulent products which occupies a volume as small as possible after use of the product.

An important object of the invention is to provide a packaging which, although composed of two elements, has a total weight which is not higher than that of a traditional bottle.

The invention also aims to provide packaging for liquid or powdery products that can be easily stacked and palletized, and having a configuration such that the ratio of the volume occupied by the size of the packaging to the volume of conditioned product is very close to the value 1, while retaining the characteristics of good compressive strength vertical presented by the traditional plastic bottles.

Another object of the invention is to provide a packaging for a liquid product composed of cardboard and plastic which can be manufactured on traditional machines, and filled on filling lines traditionally used for filling bottles.

Another object of the invention is to provide a packaging for liquid or pulverulent products which makes it possible to easily pour the product contained, preventing any overflow thereof, which can be opened and closed easily after use, and which especially allows the use of the entire product, so as to avoid any waste, and any mixture of product residues with other household or industrial waste.

A final object of the invention is to provide packaging for liquid or pulverulent products with which the risk of leaks is reduced.

The subject of the invention is a packaging for liquid or pulverulent products, which consists of an assembly consisting of a cardboard box and a plastic bottle contained in this box without being attached to it, that is to say without being glued or welded to it, so that the bottle can be separated from the box very easily and without any tearing off after this box has been opened. The box in question has side walls and a cover. An opening is made in the latter. The bottle has, a bottom, a body, shoulders, a neck and a neck, on which is fitted a stopper. The body of the bottle has sufficient flexibility so that it can substantially match the side walls of the box; his shoulders have sufficient flexibility for a pressure exerted downwards on the neck deforms them so as to retract said neck inside the box. The flexibility of the shoulders also allows that a pull exerted on the neck brings it out of the box, the bottle then occupying a position in which it can be filled by the neck, the cap can be put in place or removed when desired and the contents of the bottle can be poured through the neck.

The packaging of the invention can therefore adopt a "box position" in which the neck is retracted and a "bottle position" in which it is, on the contrary, prominent.

The cardboard box can possibly be devoid of bottom (on the opposite side of the cover in which an opening is made).

This box can however be provided with a bottom.

This bottom may possibly be incomplete and formed, for example, of the edges of the side walls folded inwards at the bottom of the box, the width of these edges being such that an opening remains in the middle of this bottom of the box.

According to a particular embodiment, the neck of the bottle is threaded and the stopper is correspondingly threaded.

However, this type of closure of the neck is by no means critical and many other closure systems can be used such as, for example, "bayonet" closure systems.

According to a preferred embodiment of the packaging of the invention, the neck of the bottle is provided, at least over part of its height, with means which can cooperate with the cover of the box to ensure the maintenance of the neck in outside of this box when the collar is engaged in the opening. These means may consist of a collar which surmounts the lower part of the collar.

Advantageously, the neck of the bottle can also be provided, at its lower part, with means which cooperate with the cover to ensure the rotational locking of the neck (and therefore of the whole bottle) when said neck is engaged in the opening of the cover. The lower part of the neck and the edges of the opening can be notched. They can also have a shape which is not circular, for example an oval, elliptical or polygonal shape. We will successfully use hexagonal, octagonal, square or even triangular shapes.

When the neck is retracted inside the box, it is advantageous that the plug does not fully fit there. To this end, the stopper will advantageously be provided with a stop member, which may consist in a simple manner of a shoulder located near the top of the stopper.

According to a preferred embodiment, the opening in the lid of the box has dimensions such that, when the neck is retracted inside the box, the edge of this opening laterally encloses the plug and thus prevents the outlet involuntary spout with its cap out of the box, for example due to shocks which may occur during handling or transport.

According to an alternative embodiment, the cap is provided with a retaining member which, when the neck is retracted inside the box, cooperates with the underside of the cover and prevents the involuntary exit of this neck provided with its cap out of the box. It can be pins or a collar.

When the neck is retracted inside the box and you want to get it out, for example to pour the product, the operation will be facilitated by the presence, on the cap, of at least one handle intended to favor the traction of the neck out of the box.

Preferably, the body of the bottle of the packaging according to the present invention is furnished, over at least part of its height and at least part of its periphery, with stiffening means, for example grooves and ribs which can be arranged either axially or radially, or by a combination of the two.

The bottle may have substantially a circular shape, or a rectangular shape with rounded corners or any other desired shape. The box can be cylindrical or prismatic.

A particularly interesting material for the manufacture of the bottle is polyethylene, but it is also possible to use poly (ethylene terephthalate), polypropylene or other recyclable or incinerable plastics without release of harmful gases. The use of polyethylene is advantageous for more than one reason since it is particularly well recyclable.

The bottle of the packaging of the invention will generally not be self-supporting.

The packaging of the invention is not heavier than a traditional bottle of the same capacity and allows the use of up to three times less plastic material. When pouring the product, it flows continuously without causing air bubbles to rise in the bottle, which allows good precision of the orientation of the jet.

Because the external presentation of the packaging of the invention is ensured by the cardboard box, it is possible to use for the manufacture of the light bottle, plastic waste from the process of manufacturing conventional packaging. It is thus possible to manufacture a monolayer bottle entirely of recovered plastic material. Its lightness, consistency and functionality will be identical to that of a bottle made from virgin material. Only its appearance will be modified, for example in the case where the plastic material recovered comes from screen printing waste, which brings about a change in the color of the bottle.

On the other hand, the coextrusion technique now makes it possible to produce multilayer bottles, with the aim of recycling the plastic material contaminated by products and coming from the consumer trash. In order for this recycling to take place, it is essential to avoid the material having been contaminated and no longer offering the guarantees of purity commonly required of all packaging, or separated from the contents by a layer of virgin plastic material intended to avoid contact between the recycled and contaminated material and the contents of the packaging.

The color of the recycled material, tending to the most varied grays, imposes on traditional bottles also a layer of external plastic material called presentation when the color requested for the bottle is incompatible with gray.

A third layer of material, sandwiched between the first two, will allow the incorporation of waste from the manufacture of the packaging itself (waste can represent 50% of the net weight of a handle bottle, for example) and the use of genuinely recycled material, that is to say contaminated and coming from refuse ("post-consumer" recycling).

The invention makes it possible to increase the proportion of recycled material by eliminating the presentation layer, which becomes useless since it is the cardboard box which provides its attractive appearance to the packaging.

We are currently trying to develop degradable plastic packaging. One of the difficulties encountered by such projects is to determine the lifespan of the material before degradation begins.

In the packaging of the invention, the bottle is protected from light by the cardboard box until the product has been used. It therefore allows the use of plastics very rapidly degradable under the effect of light, that is to say of UV radiation. The degradation of the plastic material begins as soon as the bottle is exposed to light, that is to say as soon as it is separated from the box, either by human will or by the natural decomposition of the cardboard.

Figs. 1 to 3 show a package for liquid or pulverulent products according to the invention, designated under the general reference 1.

This package 1 consists of a cardboard box 2 of square section and a bottle 3. For ease, the bottle 3 is shown in elevation and the box 2 in section, in FIGS. 1 and 2.

The box 2 conventionally comprises a bottom 4, four side walls 5 and a cover 6. In the latter is formed a circular opening 7.

The bottle 3 is made of polyethylene; it comprises a bottom 8, a body 9 of substantially circular section, flexible shoulders 10 extending from the upper end of the body 9 to a surface 11 which constitutes the limit between the shoulders 10 and the neck 12. That -this extends in height until the start of the threading (shown in dotted lines in Fig. 1) of the threaded neck 13 on which is screwed a threaded plug 14.

The body 9 and the shoulders 10 of the bottle 3 have a thickness of approximately 0.2 mm. As seen in FIG. 4, when the bottle 3 is empty, it can easily be separated from the box 2, to which it is not attached either by gluing or by welding or in any other way. It can then be rolled by hand like a toothpaste tube, which allows it to occupy a very small volume in the waste.

This also allows recovery until the last drop of the product. Box 2, on the other hand, can be flattened like any cardboard box.

The neck 12 is divided into three distinct elements along its height: the lower part 15, the collar 16 and the upper part 17. We can clearly see in FIGS. 1 and 2 that the bottle 3 can occupy, relative to the box 2, two different positions.

Fig. 1 shows the packaging 1 in its position provided for filling or pouring the product. It can indeed be treated then as a simple bottle and in particular be filled on traditional filling lines for bottles.

The collar 16 is supported on the cover 6 and thereby maintains the flexible shoulders 10 in a stretching position; the lower part 15 of the neck 12 is engaged in the opening 7 of the cover 6. It can be locked there in rotation, for example by means of a notching (not shown) of the edges of the opening 7 and of the lower part of the neck 12. The opening 7 and the neck 12 can also be given an oval shape.

The position of the packaging 1 intended for transport and storage is shown in FIG. 2. Thanks to the flexibility of the shoulders 10, a pressure exerted vertically downwards on the neck 13 and the cap 14 allows the disappearance of the bottle 3 in the box 2. The packaging 1 can then be stacked without disadvantage, loaded on pallets and be treated during handling and handling like a regular box.

The plug 14 shown in FIGS. 1 and 2 is particularly well suited to packaging 1. At its upper part, it is provided with a shoulder 18 which rests on the cover 6 when the neck 13 enters the box 2 and therefore serves as an organ stop. Two handles 19 can be raised at its upper part so as to facilitate the manual pulling of the neck 13 out of the box 2, for example when after transport, it is desired to pour the product.

The plug 14 is provided with lugs 20 which serve to prevent an involuntary exit of the neck 13 from the box 2 during transport, by cooperating with the underside of the cover 6. When the neck 13 is pushed in, the lugs 20 penetrate under the cover 6 thanks to a temporary deformation thereof. The opening 7 of the cover 6 has a diameter such that it serves as a guide for the lower part 15 and the upper part 17 of the neck 12, even if the pressure exerted on the plug 14 is not perfectly vertical. This characteristic, combined with the existence of the shoulder 18 and the handles 19 which are foldable, provide a practically flat surface to the cover 6 of the box 2 when the packaging 1 is in its "box position" illustrated in FIG. 2.

Fig. 3 shows that the bottle 3 substantially matches the side walls 5 of the box 2. Its body 9 has, on a part of its periphery, an undulating shape, thus forming a succession of grooves 21 and ribs 22 arranged in the axial direction ( vertical). Two smooth zones 23 are also provided.

As the walls of the bottle 3 are very thin, and particularly when the package 1 is filled with liquid product, there may in the long run swell the side walls 5 of the box 2, mainly in the lower third of the package 1, where the greatest pressure is exerted. To overcome this drawback, the body 9 of the bottle 3 has, in the corresponding zone, a slightly smaller section than in the other parts, of so as to counteract the appearance of such swelling. This characteristic is of course not apparent when the bottle 3 is filled.

Figs. 5 to 7 represent another embodiment of a package 24 according to the invention.

A box 25 of rectangular section contains a bottle 26. The package 24 can adopt the position "bottle position" (Fig. 5) or the "box position" (Fig. 6). An opening 27 of hexagonal shape is provided in the cover 28.

The body 29 of the bottle 26 has a substantially rectangular section with rounded corners and is furnished, over its entire height and over its entire periphery, with grooves 30 and ribs 31. It substantially matches the shape of the side walls 32 of the box 25 The neck 33 of the bottle 26 surmounts a substantially rectangular surface 34 with rounded corners. It has a lower part 35 of hexagonal shape which cooperates with the edges of the opening 27 when the packaging is in the "bottle position", so that the bottle 26 is locked in rotation in the box 25. The setting in rotation is mainly intended to avoid, when screwing the cap 14, a twist of the body of the bottle in the case of bottles having a non-circular section.

In this "bottle position", the bottle 26 is also wedged in height by means of the collar 36 which bears on the cover 28. It can be seen in FIG. 5 that the height of the box 25 (from its bottom 37 to its cover 28) is slightly greater than that between the bottom 38 of the bottle 26 and the collar 36 thereof. It follows that, when the neck 39 sinks into the box 25 under the action of a pressure exerted vertically downwards on the stopper 14, the bottle 26 descends slightly until its bottom 38 touches the bottom 37 of the box 25 with, as a result, reduced deformation of the shoulders 40 of the bottle 26.

With respect to the embodiment described with reference to Figs. 1 to 3, the advantage of this variant of execution is that it allows, for an equal product content, to manufacture a bottle 26 having a smaller volume and therefore to reduce the quantity of plastic material used. It is obvious that the strength of the cardboard which constitutes the cover 28 is sufficient to support the weight of the filled bottle 26 without deforming, and this so that the collar 36 does not risk descending into the box 25 in the absence of another downward pressure on the neck 39.

Many variants can be made to the packaging described above without departing from the scope of the invention.

Thus, bottles, in substance of cylindrical shape, can be adapted as well to boxes of square, hexagonal or octagonal section, for example, as to cylindrical boxes themselves.

Bottles can be made with the body lined with horizontal grooves, or a combination of horizontal and vertical grooves, or bottles stiffened with diamond-shaped relief patterns, or even smooth bottles.

The shapes of the neck of the bottle and the opening in the lid of the box can be chosen as required, and regardless of the shape chosen for the box and the bottle of the packaging.

In an advantageous embodiment not shown in the figures, the opening of the cover of the box can have a polygonal shape, for example, hexagonal. The lower part of the neck of the bottle has a corresponding shape. There is no collar, but the lower part is surmounted by a smooth zone corresponding to the thickness of the cover, this smooth zone being itself surmounted by an upper part of the neck having the same polygonal shape and the same dimensions than the lower part, but with an angular offset with respect to the latter so that, when the lower part is engaged in the opening of the cover, the bottom of the upper part is supported on the cover, thus ensuring a blocking in height. This embodiment has the advantage of keeping the edges of the opening perfectly intact.
