Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims priority from Italian patent application no. 102018000008492 filed on Nov. 9, 2018, the entire disclosure of which is incorporated herein by reference.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to packaging for the in-line stocking and transportation of bottles, especially but not exclusively for pharmaceutical use.

The term “packaging” refers, here and in the following, to a closed container formed by at least two elements or components that can be coupled to one another. The term “in-line” instead refers, here and in the following, to the fact that at least one of the components of the packaging is adapted to be used immediately downstream of a production plant for the glass bottles and/or of a silicon coating line thereof.

PRIOR ART

It is known that glass bottles and/or glass vials for pharmaceutical use are produced from a glass tube, which is cut and shaped into the desired shape by flame. The bottles or vials thus obtained are subjected to a stress relieving heat treatment and, subsequently, are also subjected to a silicone coating treatment, by means of which the bottles or vials are internally siliconized, i.e. their inner surface is coated with a thin layer of liquid silicone, at the end of the production steps, successively baked to ensure perfect adhesion to the walls of the bottle.

Immediately after the silicone coating or, in any case, immediately after baking the silicone layer, the bottles (or vials) are arranged vertically and with a slight clearance between one another, almost in contact with one another, inside a rectangular box, with their respective inlets facing upwards. This box is used to carry out further handling and the transport to the place of use.

However, when the glass bottles come into contact with each other during the handling of the box, they produce noise and above all the outer surface thereof can be damaged (with the formation of scratches) or even they may break. This produces unwanted waste that greatly increases production costs and can lead to returns of the bottles to the manufacturer from the customers.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a packaging for the scratchproof in-line stocking and transportation of glass bottles (or vials), especially but not exclusively for pharmaceutical use, preferably immediately downstream of the production step, which can be easily handled, of low cost, simple to produce and which, at the same time, avoids any noise and/or damage to the bottles/vials.

Therefore, according to the invention, a packaging is provided for the scratchproof in-line stocking and transportation of glass bottles (or vials), especially but not exclusively for pharmaceutical use, having the characteristics disclosed in the attached claims.

DETAILED DESCRIPTION

With reference to Figures from 1 to 5, number 1 denotes, as a whole, a packaging for the in-line stocking and transportation of glass bottles 2, especially but not exclusively for pharmaceutical use.

In the non-limiting embodiment illustrated, the packaging 1 is intended to receive bottles or “vials” 2 for pharmaceutical use, of a known type, but it is clear that the packaging 1 of the invention, that will be described, can receive other types of glass containers, for example vials, so the term “bottle” should not be referred to in a limitative sense here and in the following.

The packaging 1 comprises a box 3 closed on five sides and open at the top, configured to house a plurality of bottles 2 therein, arranged neatly side-by-side in a vertical position.

In the non-limiting, but preferred embodiment of the invention illustrated herein, the box 3 is a parallelepiped-shaped box and is delimited by four side walls 4, 5, 6 and 7, arranged, two-by-two, adjacent and perpendicular to each other, and by a flat bottom wall 8 (not shown in FIG. 1 but shown in FIGS. 2 and 3). The box 3 can be made, by moulding, in a synthetic plastic material, or it can also be metal, for example obtained by shearing and folding a metal sheet.

The packaging 1 further comprises a lid 9 couplable in a removable manner with the box 3, in a position facing the bottom wall 8 of the box, to close the box 3 itself at the top.

According to a first characteristic of the invention, the lid 9 is provided, on a first face 10 thereof, configured to be turned in use towards the bottom wall 8 of the box, with a plurality of first spacer elements 11 and second spacer elements 12, which project in a cantilever fashion from said face 10 of the lid 9 and towards the bottom wall 8 of the box 3.

According to the invention, the first spacer elements 11 are configured to be interposed, in use, between each bottle 2 contained in the box 3 and respective other bottles 2 immediately adjacent thereto (FIGS. 4 and 5).

The second spacer elements 12 are arranged near a peripheral edge 13 of the lid 9 and are configured to be interposed between the bottles 2 and a respective side wall 4, 5, 6, 7 of the box depending on which of these is adjacent to the bottles 2 arranged peripherally in the box 3.

According to another aspect of the invention, at least some of the second spacer elements 12 are also configured to cooperate with at least two of the side walls 4-7, in this case with the walls 4 and 6 arranged opposite and facing each other, to guide the lid 9 to couple correctly with the box 3.

In the illustrated and preferred embodiment, the packaging 1 is configured to contain glass bottles 2 each being delimited by a cylindrical side wall 14.

In this case, the first spacer elements 11 are preferably arranged on the lid 9 forming hexagonal assemblies 15 (FIGS. 4 and 5); in particular, in each hexagonal assembly 15, each spacer element 11 is arranged according to the vertexes of a hexagon and simultaneously is part of both its hexagonal assembly 15 under consideration, and of other two hexagonal assemblies 15 immediately adjacent to the previous one.

The second spacer elements 12 are instead arranged on the lid 9 so as to form part of respective peripheral hexagonal assemblies

(FIG. 5), at least partly incomplete, formed also in part by some of the first spacer elements 11.

The peripheral hexagonal assemblies 16 are arranged immediately adjacent to the side walls 4-7.

Moreover, at least some of the second spacer elements 12 cooperate with respective joining corners 18 of the box 3 arranged between two side walls 5,6 or 6,7 or 7,4 or 4,5 in order to form guides for the coupling of the lid 9 with the box 3.

The spacer elements 11 and 12 are formed, according to a preferred aspect of the invention, by straight pegs 20 that extend in a cantilever fashion from the face 10 of the lid 9 perpendicular to the lid 9 itself; the face 10, as well as to the bottom wall 8 already described, is flat.

The spacer elements 11 and 12 and the lid 9 are preferably made of a synthetic plastic material, and the spacer elements 11, 12 are formed integral in one piece with the lid 9, having been moulded with the same by means of a single moulding operation, e.g. by injection moulding. For example, lid 9 and pegs 20 are made of a synthetic silicone plastic resin, or of PE, PP or another suitable synthetic plastic material.

Moreover, the first and second spacer elements 11 and 12 are preferably made with an identical shape and size and differ from one another only by the relative position on the lid 9.

Finally, according to the non-limiting embodiment illustrated, the spacer elements 11,12 are formed by straight pegs 20, which extend in a cantilever fashion from the first face 10 of the lid 9 perpendicular to the lid itself, and which have a constant cross-section or, at the most, tapered towards a free end 21 of the pegs 20.

The cross-section of each peg 20 preferably has a polygonal shape, even more preferably a pentagonal shape, and is delimited (FIG. 5) by sides adjacent two-by-two, alternately a straight one 22 and a curved one 23, for each pair of adjacent sides 22,23.

Finally, the length of the pegs 20 is sized so that the free ends 21 of the pegs 20 remain spaced from the bottom wall 8 of the box 3 when the lid 9 is coupled to the box 3, so as not to create unwanted interference due to the machining tolerances.

Once the processing of the bottles 2 is finished, they are stored in a box 3 directly on the processing line; possibly the box 3 can also be used to carry out the baking step of the inner silicone layer with which the side walls 14 are coated, with the bottles 2 already housed in the box 3, for example if the latter is made of metal or in any case of a heat resistant material.

Subsequently, the lid 9 is brought closer to and fitted onto the box 3 for example as shown by the arrow in FIG. 1. The pegs 20 are inserted in the interstices between the bottles 2, which are housed in the box 3 in a position adjacent to one another but with a minimum radial clearance and, at the same time, cooperate, at least at the corners 18, with at least two opposite side walls, for example 6 and 4 of the box 3 to guide the lid 9 and the respective pegs 20 in order to be inserted correctly in the box 3 and between the bottles 2, respectively.

Once the lid 9 is coupled with the box 3, the packaging 1 takes on the appearance illustrated in FIGS. 2-4, wherein the pegs 20 forming the spacer elements 11 are interposed between all the bottles 2 adjacent to one another, while the pegs 20 forming the spacer elements 12 are interposed between the bottles 2, housed peripherally in the box 3, and the side walls 4-7.

In this way, the bottles 2 cannot collide with each other, with the side walls 14, or against the side walls 4-7 of the box 3 and therefore they can neither break nor be damaged superficially, especially if lid 9 and pegs 20 are made with a soft and at least partially elastic synthetic plastic resin, such as a silicone resin.

The production cost of the lid 9 is then negligible, once the cost of the moulds is recuperated, and the assembly on the box 3 is quite simple and easy.

Optionally, snap fastening means (not illustrated for simplicity) to the box 3 can also be provided on the lid 9.

All the aims of the invention are therefore achieved.
