Description

DESCRIPTION

Packaging casing for perfume, cosmetic or toiletries bottles

The present invention relates to the field of so-called secondary packaging, in particular secondary packaging for bottles of cosmetic, toiletries or perfume products.

A cosmetic product refers, in particular, to all skin makeup products, including lip makeup, and all compositions intended for body application, including so-called care products, such as moisturizers. Toiletry products include shower gels, bath products, and body lotions. Perfumes refer, in particular, to all scented or odoriferous compositions intended for body application.

Secondary packaging is packaging formed around the primary packaging, with primary packaging being that which is in direct contact with the packaged product.

Secondary packaging is generally used to group products into batches and/or transport them to their distribution point. However, in the field of cosmetics and perfumery, secondary packaging primarily serves aesthetic and protective functions, as each individual product is packaged in one or more secondary packaging units.

Typically, several elements are used to form the secondary packaging of a product bottle (perfume, cosmetic or toiletries), with the bottle being the primary packaging for said product.

The secondary packaging of such a bottle generally includes a case, optionally a filler and a sleeve.

The case is a piece of cardboard, plastic, or other suitable material (leather, wood, etc.) that forms a housing or box for the bottle. The case usually bears the legal and commercial markings. The filler is a piece of cardboard, plastic, foam, etc., shaped to prevent the bottle from moving within the case. The filler may be configured to fit the shape of the bottle or simply to compensate for any play in the case around the bottle.

The sleeve is the outer packaging, made of paper or cardboard, that surrounds the case. Such a solution, which comprises three secondary packaging elements, is complex. It requires the supply and storage of different elements. Each element requires folding and cutting to be manufactured. The design of the secondary packaging is therefore complex. Furthermore, during packaging manufacturing (forming the packaging, placing the bottle in the packaging, etc.), several manipulations are required that can be difficult to automate. The production costs associated with secondary packaging are therefore significant in the field of bottles, particularly those for cosmetics, toiletries, and perfumes.

Furthermore, the use of plastic materials and, more generally, heterogeneous materials for secondary packaging of cosmetics or perfumes makes recycling packaging complex or impossible.

Document US 10 829 282 B1 discloses a packaging casing as claimed in the preamble of claim 1.

The invention therefore aims to propose secondary packaging for bottles that solves, in whole or in part, the aforementioned problems. In particular, it aims to propose packaging for bottles that is aesthetically pleasing and distinctive, particularly suited to the field of perfumery and cosmetic products, and that can be easily recycled or biodegraded. The packaging proposed in the invention aims to fulfill these functions while simultaneously offering a high level of protection for all the components of the bottle: the glass of the reservoir and/or the bottle cap, its label (or other form of identification), etc.

Thus, the invention relates to a packaging casing for a perfume, cosmetic, or toiletries bottle, said casing being capable of assuming a closed position in which it forms a receiving volume adapted to enclose a bottle, and an open position allowing the bottle to be placed in the casing or removed from the casing, said casing comprising two half-shells, each forming a concavity and essentially formed of a material based on molded natural plant fibers. Each half-shell comprises a peripheral edge which, when the casing is in the closed position, joins a peripheral edge of the other half-shell, such that the receiving volume is a closed volume, the casing having at least one holding element projecting into the receiving volume. The holding elements are molded with the casing.

The formation of a natural fiber shell by molding offers multiple advantages. The method of molding a natural fiber-based material allows the shell, or part of the shell, to be manufactured in a single operation. Above all, this method allows for the creation of complex and aesthetic shapes. In particular, it is possible to form a shell that adapts to the shape of the bottle it will contain, giving the shell an attractive aesthetic, especially since the shell can adopt, over all or part of its surface, the shape of the bottle. Such a shell is thus particularly aesthetic, forming a kind of skin around the bottle. The shell can thus adopt the overall shape of the bottle, making the product immediately identifiable to the consumer, particularly in the case of certain perfumes whose shape is well-known and distinctive. Furthermore, by reproducing the shape of the bottle as accurately as possible, the packaging suggests the shape and volume of the bottle, thus complying with regulations regarding the relationship between primary and secondary packaging, the aim of which is to prevent any misleading of the consumer regarding the dimensions and actual contents of the product inside the package. More generally, the packaging volume is optimized, giving the user a clear idea of the volume of the bottle inside the packaging.

The combination of the overall shape of the housing, the material used, and the presence of protruding fastening elements on the housing ensures good protection of the bottle, particularly against impacts.

The material used essentially (that is, at least for the most part) to manufacture the casing is recyclable and/or biodegradable. The method used to form the casing consists essentially of using fibrous plant pulp containing natural plant fibers and water, which is then heat-molded.

Finally, the transport of packaged products is optimized through lightweight, low-material, and compact packaging (allowing more bottles to be transported in the same volume). This reduces the carbon footprint caused by transporting packaged bottles.

The housing may comprise a hinge connecting the two half-shells.

In this way, different housing configurations can be conceived, based on one or more molded elements made of a natural plant fiber-based material.

The formation of two articulated half-shells forms a case that highlights the bottle that the shell is intended to contain.

The housing comprises an outer wall and an inner wall, the inner wall defining the receiving volume in the closed position of the housing. The outer wall of the housing and the inner wall of the housing may be formed by two distinct layers of said natural fiber-based material, namely, an inner layer forming the inner wall and an outer layer forming the outer wall, the inner layer comprising the holding means (elements). The holding elements are molded only in the inner layer, such that a gap is formed between the outer layer and the inner layer at the level of the holding elements. The aesthetic appearance, particularly the shape, of the outer layer is preserved. Furthermore, a gap may be formed between the two layers at the level of the holding elements, which improves their deformability. This allows the holding means to be more easily adapted to the manufacturing tolerances of the bottles intended to be placed in the housing and improves their ability to absorb shocks and other stresses to which the housing is subjected.

The natural fibers used may include sugarcane, bamboo, wood, cotton, linen, hemp, sisal, jute, kenaf, or coconut fibers. Bagasse (from sugarcane) or bamboo fibers are particularly preferred. The use of one or more of the aforementioned plant fibers allows for the formation of a molded "paper"-like casing with various mechanical and aesthetic properties.

The packaging casing may have, for example, a wall thickness of between 0.5 mm and 3 mm, preferably between 0.8 and 2 mm, at any point of said casing, except in the areas where a fastening element is formed.

Tests have been carried out which have made it possible to determine that said thickness allows satisfactory protection of a glass bottle, for example a standard-sized perfume bottle (e.g., 100 ml), in the event of a fall from a height of 90 cm onto a solid surface, which corresponds to a typical fall situation for a perfume or cosmetic product bottle (fall from a table, a display case, a bag, etc.). The receiving volume formed by the housing may comprise a front wall, a rear wall, and side walls connecting the front wall to the rear wall, and the holding elements comprise: at least one buttress projecting from at least one of the side walls and/or at least one shoulder projecting from at least one of the front and rear faces and/or at least one elongated rib or one defining a closed shape, on at least one of the front and rear faces.

In this way, the fastening elements can take on various shapes and dimensions, adapted to their specific function.

The clamping elements located on the internal side walls of the housing may be in the form of blocks or clamping wedges, in order to provide a relatively large support surface for the bottle contained in the housing.

The holding elements located on the front and rear faces can be in the form of small cylindrical or hemispherical protrusions that provide targeted support in selected areas of the bottle contained in the housing, while also being aesthetically pleasing.

Ribs allow for a linear support with respect to the bottle. As detailed below, the protrusions and/or ribs can form a support on the bottle around an identification area, in order to protect the identification from any damage caused by friction, even at low amplitude, against the housing.

The receiving volume may have a complex shape intended to adapt to the shape of a bottle, with the necessary separation formed by the holding elements, said complex shape comprising:

• a tank receiving volume, having a first cross section having a first surface;

• a receiving volume of a neck, having a second cross-section having a surface area lower than the first surface;

• a plug-receiving volume, having a third cross-section having a surface comprised between the first surface and the second surface.

The shape of the shell as close as possible to the bottle it contains offers good protection for the bottle and good aesthetics of the shell, as it perfectly reproduces the general shape of the bottle it contains and thus benefits from its distinctive appearance.

The invention also relates to an assembly comprising a packaging casing for a bottle as defined above and a bottle contained in said packaging casing.

In said assembly, the casing can be adapted to the external shape of the bottle it contains, so that at any point of said casing there is a maximum separation of 4 mm, preferably 2 mm maximum, between an external wall of the bottle and the internal wall of the casing.

In addition, the holding elements may be configured to hold the bottle at a distance from the front, rear, and side walls of the housing.

When the bottle includes an additional identification, the holding elements can be configured so that the additional identification is held at a distance from the housing and that said holding elements are not in contact with said additional identification. In this way, the housing is configured for optimal protection of the bottle it contains. The housing can completely enclose said bottle, so that no part of the bottle protrudes from said housing when the latter is closed. This provides protection for the entire bottle. Furthermore, by enclosing the neck and the cap of the bottle, the housing, when closed, helps prevent the cap from being accidentally removed.

The jar can advantageously be a glass jar.

Due to its construction and aesthetics, the case is specifically designed to protect a glass bottle, which is naturally sensitive to impacts. A glass bottle refers to any glass bottle, of any type, including crystal.

Other particularities and advantages of the invention will become apparent through the following description.

The attached drawings are offered as non-limiting examples:

Figure 1 represents a glass bottle, specifically a perfume bottle, which constitutes a preferred application of the invention;

Figure 2 shows, according to a three-dimensional schematic view, a packaging casing in the open position, according to an embodiment of the invention adapted to the bottle of Figure 1; Figure 3 is a three-dimensional schematic partial view of the casing of Figure 2;

Figure 4 shows, according to a three-dimensional schematic view, a packaging casing in the open position, according to another embodiment of the invention adapted to the bottle of Figure 1; Figure 5 shows, according to a schematic cross-sectional view, the packaging casing of Figure 2 in the closed position;

Figure 6 represents, according to a three-dimensional schematic view, the housing of Figures 2 and 3, in the closed position.

Figure 1 shows a glass bottle, specifically a perfume bottle. Although the invention can be applied to packaging any type of bottle, it is particularly suitable for glass bottles due to the good level of mechanical protection it provides.

The bottle 1 shown in Figure 1 comprises a body 2 forming a reservoir for the perfume and a neck 3. The neck 3 comprises an opening allowing the perfume to be introduced into the reservoir of the body 2 and the perfume to be released from the reservoir of the body 2. In the example shown here, the neck 3 comprises means for dispensing the perfume, namely a pump and a push button. The neck 3 is crowned by a cap 4 allowing the neck 3 to be closed and/or the dispensing means to be covered.

With the exception of the dispensing means, the bottle in Figure 1, and in particular its cap 4, is made entirely of glass. Therefore, this type of bottle requires mechanical protection, particularly against impact, for all its constituent parts.

Moreover, this type of bottle has a complex, yet particularly aesthetic and distinctive overall shape, which should be highlighted even when the bottle is packaged.

Figure 2 shows a packaging casing 5 according to an embodiment of the invention. This casing is shown in the open position. This casing is designed to accommodate, protect, and enclose the bottle 1 shown in Figure 1.

The open position of the housing 5 shown in Figure 2 corresponds to a position in which the bottle 1 can be placed in the housing 5 or removed from the housing 5. The housing 5 comprises a first half-shell 6 and a second half-shell 7. The first half-shell 6 and the second half-shell 7 are connected to each other by a hinge 8. The hinge 8 allows the housing 5 to pass from its open position to a closed position in which it forms an interior volume adapted to enclose the bottle 1.

Both the first half-shell 6 and the second half-shell 7 have a concave shape adapted to receive the bottle 1.

Since the bottle 1 in Figure 1 has two vertical planes of symmetry, the housing 5 is in turn formed by two half-shells 6, 7. The first half-shell 6 and the second half-shell 7 can be symmetrical with respect to the axis formed by the hinge 8.

Figure 3 represents a part of the casing 5 of Figure 2, that is, the first half-casing 6, according to a perspective view that allows to appreciate certain details of the interior of the concavity of the half-casing 6.

The complex concave shape of each half-shell is obtained by molding a material based on natural plant fibers. Shell 5, in particular, is made primarily from molded plant pulp, as hot molding the pulp allows the material to be shaped perfectly to the contours of the bottle to be packaged.

The pulp is advantageously obtained from bagasse fibers and/or bamboo fibers.

Other natural fibers can be used, depending on the desired appearance and properties, particularly mechanical properties. The natural fibers used can generally be all fibers used in the paper industry, in particular, in addition to sugarcane fibers (in the form of bagasse) and bamboo, and particularly wood, cotton, flax, hemp, sisal, jute, kenaf, or coconut fibers. Any blend containing these fibers is also possible.

The first half-shell 6 and the second half-shell 7 can be made from a single piece, in which case the hinge 8 is formed by folding the two half-shells together. Alternatively, each half-shell can be formed from a separate piece and the hinge from a mating piece.

In the exemplary embodiment of Figure 2, the hinge 8 is positioned in the area of the housing 5 intended to accommodate the bottom of the bottle 1. This makes the hinge 8 barely visible, improves the aesthetics of the whole and allows for a natural opening of the housing. Obviously, within the scope of the invention, the housing could be opened laterally by means of a lateral hinge, which would allow the housing to be opened in a manner similar to opening a book. The housing 5 has the particularity of having fastening elements 16. The fastening elements 16 are elements that protrude inside the housing 5, that is, inside the receiving volume 10 that the housing 5 forms when it is in the closed position.

The clamping elements 16 can have several functions. First, they compensate for the manufacturing tolerances of the bottle housed in the housing. The manufacturing tolerances of a glass bottle can be significant in relation to the dimensions of said bottle. To compensate for these manufacturing tolerances, the clamping elements are adapted to be slightly compressed when a bottle is placed in the housing 5. Once in place, the bottle is perfectly immobilized in the housing 5.

Another function of the holding means 16 may be to maintain a space between the bottle placed in the housing 5 and the walls of said housing 5.

This is particularly advantageous when the bottle packed in the casing includes an additional identification. The additional identification may be a label 15 bearing a print, a lacquer, a varnish, or a silkscreen, etc., and which is affixed to the bottle 1 (see Figure 1). The additional identification may alternatively be a lacquer, a varnish, a print, or a silkscreen produced directly on the bottle 1. Such an additional identification may be damaged or even erased by the bottle 1 rubbing against the casing 5. Keeping the additional identification at a distance from the wall of the casing 5 prevents this type of damage.

Finally, and most importantly, the holding elements 16 contribute to protecting the bottle contained in the housing 5 against impacts, in particular in the event of the housing 5 containing a bottle 1 falling.

In order to satisfy the different functions of the clamping means 16, various configurations, in terms of geometry and position in the housing 5, of the clamping means can be used.

In the housing example shown in Figure 2 and Figure 3, the housing comprises a front wall 18, a rear wall 19 and side walls 20.

The side walls 20 may be provided, as fastening means 16, with reliefs referred to as buttresses 161. The buttresses 161 are small, parallelepiped-shaped or "wedge-shaped" additional thicknesses, i.e., having a regularly varying thickness. Two buttresses 161 may be provided on each side wall of each half-shell, or on only one of the half-shells, i.e., four or eight buttresses in total in a shell 5. In the example shown, eight buttresses 161 are formed in the shell 5.

As can be seen in Figure 3, the buttresses 161 may have an inclined edge 164 that facilitates the insertion of a bottle 1 into the housing 5.

The front wall 18 and/or the rear wall 19 may be provided with projections 162 or with one or more ribs 163 as a holding element. In the exemplary embodiment shown, the front wall 18 comprises one rib 163 and the rear wall 19 comprises four projections 162.

Ribs and protrusions can be used to perform similar functions. In general, a protrusion 162 provides a small area of contact with the bottle 1, for example, a nearly point-like contact area, while a rib 163 provides linear contact with the bottle 1.

In the example shown, the rib 163 has a configuration in which it defines a closed shape, in this case substantially a rectangle. The rib can define various closed shapes: circle, oval, square, rectangle, or any other shape. The rectangular shape of the rib 163 in the example shown here allows a support to be created on the bottle 1 around the label 17 (or any other identification applied to the bottle 1) in order to offer optimal protection of said identification.

Four projections 162 positioned towards the corners of the bottle 1 also provide a space between the bottle (and in particular its identification) and the wall of the housing 6.

When the bottle is placed in the housing 5, the holding means 16 can be deformed to a greater or lesser extent.

In the exemplary embodiment shown in Figure 2 and Figure 3, both the first half-shell 6 and the second half-shell 7 comprise a peripheral edge 9 which is in contact with the peripheral edge 9 of the other half-shell when the shell 5 is in the closed position. The joining of the side walls 20 of the two half-shells is thus carried out edge to edge, or, where appropriate, with a slight overlap between said side walls 20 of the first half-shell 6 and the second half-shell 7, respectively.

A very sharp peripheral edge 9 can be obtained by cutting the half-shells with the aid of a cutting tool. This cut is made after the half-shells have been molded and, where appropriate, after the two layers comprising the half-shells have been assembled, as detailed below. This cut is advantageously performed using a blade or by machining, in particular by cutting with a cutting ring.

Figure 4 represents, according to a three-dimensional schematic view, a packaging casing in the open position. The casing 5 of Figure 4 corresponds essentially to that of Figure 2, so that the description of Figures 2 and 3 essentially applies to the casing 5 of Figure 4, with two exceptions: the type of fastening elements 16 used in the casing and the presence of a flat portion 21 on each half-casing.

As regards the fastening elements 16, there are projections 162 formed on the front wall 18 instead of the rib 163 of the embodiment of Figure 2 and Figure 3. As previously explained, these two alternatives allow substantially similar functions to be obtained.

With respect to the flat portions 21, each half-shell 6, 7 forms a recess adapted to the bottle 1. Instead of having a thin lateral edge around the recess, a flat portion 21 surrounds the recess of each half-shell. When the shell 5 is in the closed position, the flat portion of the first half-shell 6 is, over all or a portion of its surface, in contact with all or a portion of the flat portion of the second half-shell 7. This allows, in particular, a tight closure of the shell 5. This also makes it possible to give the shell 5 the desired shape in the plane of contact of the flat portions of the two half-shells, that is, in this case, a generally rectangular shape.

The flat portions 21 can also be used to ensure the closure of the casing 5 by means of a locking device 22 adapted to hold the casing in the closed position. In the example shown in Figure 4, a hole 23 is made in each of the flat portions of the two half-shells, so that the holes 23 are aligned when the casing 5 is brought into the closed position.

The locking device 22 is positioned in the holes 23 and holds the respective flat portions 21 of the two half-shells against each other, at the level of the holes 23. The locking device may be a coupled latching system. Alternatively, only one of the two half-shells may comprise a hole 23, and the other of the two half-shells may comprise a deformation adapted to lock in the hole 23 to ensure locking of the shell 5.

Finally, as an alternative or complement to the case's closure function, the flat parts can be used to adapt the packaging to specific displays. For example, a hole can be formed to hang the case 5 from a blister pack hook, commonly used in stores.

Figure 5 shows, according to a schematic cross-sectional view, the packaging casing of Figure 2 in the closed position. Figure 5 shows, more particularly, the packaging casing 1 seen according to the section plane A-A represented in Figure 4.

In the closed position, the side edges 9 of the half-shells 6, 7 come into contact. Due to the concavity of the two half-shells 6, 7, the housing 5 forms, in the closed position shown in Figure 3, a receiving volume 10 configured to accommodate and enclose the bottle 1. As can be seen in Figures 2 and 3, the receiving volume 10 is configured to adapt to the general shape of the bottle 1. Thus, when the bottle 1 is in the housing 5, there is at most a very small gap between the housing 5 and the bottle 1, that is to say between the inner wall 11 of the housing 5 and the bottle 1. Typically, a maximum gap of 4 mm, or even less, for example a maximum gap of 1 mm, can be left between the inner wall 11 of the housing 5 and the bottle 1. Furthermore, thanks to the fastening means 16 comprised in the housing 5, the bottle is immobilized without gap in said housing 5.

In this way, the bottle 1 can be pressed into the housing 5, so that it is held by friction between certain clamping elements 16 (typically the buttresses 161) and the bottle 1.

The housing 5 can be held in the closed position by any known means. For example, an adhesive can be applied to the junction between the first half-shell 6 and the second half-shell 7. Any other closure means, whether reversible or not, can be used. For example, a local overlay can be conceived between the side edges 9 of the first half-shell and the second half-shell. At the level of this local overlay, an additional thickness can be formed on one of the half-shells during or after molding the half-shells, which is received in a corresponding housing of the other half-shell. In this way, a latching closure can be obtained.

The figures allow to appreciate the complex geometry of the receiving volume 10 that can be obtained in the invention to correspond to the general shape of the bottle 1. In this way, the receiving volume 10 can be formed by a plurality of volumes with different geometries.

Thus, in the example shown, we can distinguish:

• a deposit receiving volume of 101,

• a receiving volume of a neck 102,

• a receiving volume of a 103 cap.

The cross-section of the receiving volume varies considerably between the different volumes that comprise it, and even within each of these constituent volumes. In the example shown, the receiving volume of the tank has a first cross-section S1 having a first surface; the receiving volume of a neck has a second cross-section S2 having a surface smaller than the first surface S1; and the receiving volume of a cap has a third cross-section S3 having a surface comprised between the first surface and the second surface.

The cross-sectional view of Figure 3 presents another optional aspect of the invention.

Thus, according to one embodiment of the invention, a casing is proposed whose half-shells 6, 7 (or each half-shell if obtained separately) comprise two layers. More particularly, each half-shell comprises an inner layer 13 and an outer layer 14. The inner layer 13 and the outer layer 14 are molded independently of each other and then assembled to form the half-shells.

The inner layer and the outer layer are assembled in this way, fitted inside each other and, for example, glued together.

In this way, the clamping elements 16, for example the projections 161 shown in Figure 5, are obtained by a local deformation of the inner layer 13 only. Compression of the clamping element is facilitated and its capacity to absorb a shock is improved, due to the presence of a space 24 between the two layers at the level of the clamping element 16. However, the external appearance of the casing is not altered.

Depending on the mechanical properties of the materials considered, the thickness of the casing that provides the desired level of protection, particularly against impacts, is around 1 mm.

In the case of a casing comprising an inner layer 13 and an outer layer 14 assembled together, the total thickness is obtained by adding the thickness of each layer. For example, a total thickness of approximately 1 mm can be obtained by assembling two layers, each with a thickness of approximately 0.5 mm.

In general, and depending on the bottle to be protected, a thickness greater than 0.5 mm, and preferably greater than 0.8 mm, seems adequate to protect a glass bottle of traditional dimensions for a perfume or a cosmetic or toiletries product. A casing with a thickness between 0.5 mm and 3 mm, preferably between 0.8 mm and 2 mm, therefore seems adequate to protect such a bottle.

The housing may have a substantially constant wall thickness over its entire surface (substantially constant means, for example, constant with a variation of plus or minus 0.2 mm).

However, the molding method also allows for the manufacture of a shell with a variable wall thickness, for example, to protect the most fragile or exposed areas of the bottle (rims, bottom, cap) with a thicker wall. This variation in thickness is combined with the presence of retaining elements to protect the bottle.

Thus, the casing may have a nominal wall thickness of between 0.5 mm and 3 mm, preferably in the range of 1 mm to 1.2 mm, the casing wall having, at least over most (or all) of its surface, a thickness equal to the nominal thickness with a variation of plus or minus 0.2 mm, preferably plus or minus 0.1 mm.

Figure 6 represents, according to a three-dimensional schematic view, the housing of Figures 2 and 3, in the closed position.

Figure 6 shows that the casing 5, which surrounds the bottle 1, forms a lining around this bottle, so that the general shape of the casing reproduces the external shape of the bottle and thus forms an aesthetic and distinctive case for the bottle.

As can be seen in the various figures presented, the molding technique of a pulp from one or more fibrous plants used to form the casing 5 allows for complex three-dimensional shapes, with reduced draft angles and well-defined edges. This is not possible with other forming techniques, such as thermoforming.

Molding also makes it possible to create a three-dimensional pattern or a three-dimensional structure (e.g., embossing) on the surface of the casing. Finally, in the example shown, a printing area 15 is provided on the casing, intended, for example, for printing a logo, a trademark, a trade name, etc. The printing area 15 may in particular be an unstructured area, optionally delimited by forming a recess or relief relative to the rest of the casing 5. The invention thus developed makes it possible to obtain secondary packaging for a perfume, a cosmetic product, or a toiletries product, in particular a packaging for a bottle, which has numerous advantages. The product, enclosed in a casing, is adequately protected. In particular, the fastening elements comprised in the casing according to the invention ensure a firm hold of the product in the casing and contribute to its protection against impacts. The manufacturing tolerances of the bottle, which are potentially significant for a glass bottle, are compensated for by the fastening elements. The unique packaging consisting of the shell replaces three packaging elements currently used: the case, the filler, and the sleeve. Because the shell tightly encloses the bottle, it is less bulky than the secondary packaging currently used, reducing the total volume occupied by the products in their secondary packaging and thus lowering storage and transportation costs. Finally, the material that makes up the packaging shell is recyclable and biodegradable.
