Definitions

  • the present invention relates to a packaging for liquid or pulverulent products suitable noting for food products and chemicals.
  • 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.
  • the glass containers are also breakable, which is a major drawback; metal containers are easily irreversibly deformed in the event of a fall.
  • the plastic containers are as light as possible.
  • 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.
  • the milk carton type plasticized cardboard boxes 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.
  • the method of opening milk carton boxes is as follows: the user must raise 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.
  • 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.
  • 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 rectangular shape of the box, it is also practically impossible to empty it.
  • 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 as small a volume 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 contained product, preventing any overflow thereof, which can be opened and closed easily after use, and which above all 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.
  • EP-A-0 264 606 discloses a packaging according to the preamble of claim 1.
  • the subject of the invention is a packaging according to claim 1.
  • the packaging is intended for liquid or pulverulent products, and consists of an assembly made up of a cardboard box and a plastic bottle contained in this box without being attached to it, i.e. 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; its shoulders have sufficient flexibility so that 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.
  • the neck of the bottle is threaded and the cap is threaded correspondingly.
  • 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.
  • 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.
  • the stopper When the neck is retracted inside the box, it is advantageous that the plug does not fully fit there.
  • the stopper will advantageously be provided with a stop member, which may consist simply of a shoulder located near the top of the stopper.
  • 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 neck with its cap out of the box, for example due to shocks which may occur during handling or transport.
  • 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.
  • 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.
  • 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, radially, or by a combination of the two.
  • stiffening means for example grooves and ribs which can be arranged either axially, 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.
  • 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 accuracy of the orientation of the jet.
  • the cardboard box 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.
  • 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.
  • 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.
  • 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.
  • 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 packaging 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.
  • 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.
  • Box 2 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 package 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 stopper 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.
  • 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.
  • the body 9 of the bottle 3 has, in the corresponding zone, a slightly smaller section than in the other parts, 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 follows 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 especially 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.
  • the bottle 26 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.
  • the advantage of this variant of execution is that it allows, for an equal product capacity, to manufacture a bottle 26 having a smaller volume and therefore to reduce the quantity of plastic material used. It is obvious that the resistance 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.
  • 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, while remaining within the framework defined by the revendications
  • 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 locking in height.
  • This embodiment has the advantage of keeping the edges of the opening perfectly intact.
