Definitions

  • the present invention relates to a packaging for liquid or pulverulent products suitable in particular 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. Glass containers are also breakable, which is a major drawback; metal containers are easily deformed irreversibly in the event of a fall.
  • 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.
  • Cardboard boxes, light and resistant are particularly appreciated: they allow good use of space, are easy to stack and palletize, and their volume can be reduced after use.
  • plasticized cardboard boxes of the milk brick type which contain a small amount of plastic material and occupy a reduced volume in the garbage after use, provided that care is taken to flatten it.
  • 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.
  • 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 parallelepiped 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 which can, if necessary, be treated as a bottle or as a box.
  • This packaging can be manufactured by traditional machines and filled by the neck on filling lines traditionally used for filling bottles. It will allow, in use, easy pouring of the product and good orientation of the jet, as can be done with a simple bottle. It can also, during handling, transport and storage, be stacked on other packaging and palletized as a simple box.
  • 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 provided in this last.
  • the bottle has a bottom, a body, shoulders, a neck and a neck, on which a cap is fitted.
  • the relative dimensions of the bottle and the box are such that the bottle can be placed either in a position in which its bottom is located at the same level as the lower end of the side walls of the box and its neck is retracted into the box, or in another position in which its bottom is located above the level of the lower end of the side walls of the box, its neck then being engaged in the opening of the cover.
  • the bottle can be moved vertically from one position to another and vice versa.
  • the bottle, as contained in the box can be filled through the neck, the cap can be put on and removed when desired, and the contents of the bottle can be poured through the neck.
  • the neck of the bottle is provided with means which, when it is engaged in the opening, cooperate with the cover to ensure that the neck is kept outside the box and the bottle is suspended therein.
  • the cardboard box could possibly be devoid of bottom (on the side opposite the lid in which an opening is made), but it is generally preferable that the box has a bottom.
  • This bottom of the box may however 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. box.
  • the neck of the bottle is threaded and the stopper is correspondingly threaded.
  • the body of the bottle can have flexibility and dimensions in width such that it substantially matches the side walls of the box.
  • the means which can cooperate with the cover of the box to ensure the maintenance of the neck outside the box and the suspension of the bottle in the box when the neck is engaged in the opening may consist of a collar which surmounts the lower part of the collar.
  • 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 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 threaded plug will advantageously be provided with a stop member, which may consist simply of a shoulder located near the top of the plug.
  • 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 out of the box, for example , following shocks which may occur during handling or transport. It can be pins or a collar.
  • 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 cap and thus prevents involuntary exit neck (with its cap) out of the box.
  • 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 or radially, or by a combination of the two.
  • 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 of 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 may not be self-supporting, its stability being ensured by the box itself.
  • the packaging of the invention is not heavier than a traditional bottle of the same capacity and, in certain embodiments, makes it possible to use up to three times less plastic.
  • 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.
  • 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 prevent the material that has been contaminated and no longer offering the guarantees of purity commonly demanded from all packaging from being separated from the content by a layer of virgin plastic material intended to prevent 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 matter actually recycled, 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 powdery products according to the invention, designated under the general reference 1.
  • This package 1 consists of a cardboard box 2 of rectangular 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 hexagonal opening 7.
  • Bottle 3 is made of polyethylene and is extremely light; it comprises a bottom 8, a body 9 of substantially rectangular section with rounded corners, and 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. This extends in height up to the start of the threading (shown in dotted lines in FIG. 1) of the threaded neck 13 onto which is screwed a threaded plug 14. This plug 14 makes it possible to open and close the packaging 1 as many times as desired.
  • the bottle 3 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.
  • packaging of the invention which allows complete separation of the cardboard and plastic components, is particularly advantageous from an ecological point of view: these components can be sorted, collected selectively and recycled.
  • the neck 12 is divided into three distinct elements along its height: the lower part 15, the collar 16 and the upper part 17.
  • the bottle 3 can occupy, relative to the box 2, two different positions. It can pass from one to the other thanks to a pressure or traction force exerted on the neck 13.
  • Fig. 1 shows the package 1 in its "bottle position" in which the neck 13 is completely pulled out of the box 2.
  • the package 1 can be treated as a simple bottle; after removal of the cap 14, the product contained in the bottle 3 can be poured. Due to the flexibility of the walls of the bottle 3, the product flows, during pouring, in a regular and well oriented jet.
  • the lower part 15 of the neck 12 is engaged in the opening 7 of the cover 6, where it is locked in rotation, thanks to its hexagonal shape and to the hexagonal shape of this opening 7.
  • the neck 13 is held in a prominent position.
  • the bottom 8 of the bottle 3 is kept at a distance from the bottom 4 of the box 2, which amounts to saying that the bottle 3 is suspended in the box 2 thanks to the cooperation of the collar 16 and the cover 6.
  • the resistance of the cardboard which constitutes the cover 6 is sufficient to support the weight of the bottle 3, even when the latter is completely filled with liquid or powdery product.
  • the cover 6 is capable of temporarily deforming while bending downwards when a downward pressure is exerted on the neck 13.
  • the collar 16 then passes under the cover 6, and the bottle 3 gradually descends into the box 2 until its bottom 8 rests on the bottom 4 of the box 2 and its neck 13 is completely retracted into this box 2, as shown in Fig. 2.
  • This position is particularly advantageous for the transport and storage of the packaging 1, which can then be stacked without disadvantage, loaded on pallets and be treated during handling and handling like an ordinary box.
  • the packaging 1 can be filled, by the neck 13, on usual filling lines for bottles.
  • This filling can possibly be done when the neck 13 is in the prominent position (that is to say when the package 1 is in "bottle position" as shown in FIG. 1, but before the plug 14 is put in place. obviously).
  • 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 is supported on the cover 6 when the neck 13 has returned to the box 2 and is therefore used for stop device. 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 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 and 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, in this preferred embodiment, the bottle 3 substantially matches the side walls 5 of the box 2.
  • Its body 9 has a wavy shape, thus forming a succession of grooves 21 and ribs 22 arranged in the axial direction (vertical).
  • 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.
  • vials in essence 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.
