The invention relates to the domain of compacts used to package makeup products, typically makeup powders.
In general, compacts typically comprise:
A very large number of embodiments of compacts are known, which may relate to one or several constituents of the compact, particularly to the closer or opening of the compact.
Thus, some of the patents issued by the inventors include:
As is clear from the state of the art mentioned, compacts according to the state of the art simultaneously have a very wide variety of technical features, and also are very similar in shape despite these technical features. In fact, all these compacts are typically round, rectangular or oval compacts, which are not particularly different from each other apart from the decor, the technical features usually being related to handling of the compact and are located at the hinge, the inner frame, the closer, the leak tightness of the compact, etc., and these features are not even visible when the compact is closed, since they are typically deliberately made invisible or hardly visible, so that the “technical” aspect of the compact is cannot be seen.
Therefore one major problem that arises in the domain of compacts is to renew and diversify available compacts. The offer on sale is firstly visual, what the potential purchaser sees on the display unit. Therefore, it is essential for purchasing the compact.
The purpose of the invention is to define technical means that enable such renewal and diversification of the offer.
According to the invention, the compact that will be placed on a typically horizontal plane support H comprises a bottom, a cover, a hinge fixing the said cover to the said bottom directly or through a inner frame fixed to the said bottom, so as to enable opening of the said compact by rotation of the said cover with respect to the said bottom, and a closing means typically consisting of a closer, the said cover and the said bottom defining an average opening plane P of the said compact, typically parallel to the said hinge, the said cover and the said bottom forming a junction defining a closed external contour C in the said plane P, the said cover being closed and is characterised in that:
The minimum angle αM is the angle between the straight line normal to the plane P and passing through the centre of gravity G, and the straight line GF passing through the edge of the support surface S closest to the said normal straight line, such that this angle is equal to the minimum rotation to be applied to the said compact before it tips. For example, see
Preferably, the minimum angle αM may typically vary from α1=20° to α2=40°, compacts with an angle αM varying from 25° to 35° being particularly slender and stable.
The combination of means a) to c) according to the invention provides a means of solving the problem that arises. It opens the opportunity for a complete new family of compacts that can potentially have an infinite variety of shapes.
Essentially, the invention has radically modified the technical elements of known compacts according to the state of the art, and their topological relation; in compacts according to the state of the art in particular, the said plane P is typically parallel to its bearing surface A on a plane support that defines a support surface or polygon S, while it is typically perpendicular to its bearing surface in compacts according to the invention.
Therefore, the invention has transformed the topological organization between the technical elements of compacts, since all compacts including compacts according to the state of the art comprise a average opening plane P of the said compact, and a bearing surface defining a support surface or polygon S on a typically horizontal plane support, the compacts forming part of objects designed to be placed on a typically plane and horizontal surface and not, for example, objects intended to be attached by a hook or placed in compartments.
Furthermore, by convention compacts are typically represented as being placed on a horizontal support, such that every compact has a vertical direction and a bearing surface that is always immediately identifiable.
Furthermore, note that the means according to the invention are completely unrelated to the shape itself of the said compacts. The means according to the invention do not define an external shape, but rather a topology, the outside shape of the compacts according to the invention may be arbitrary provided that the said compact satisfies the combination of technical requirements a) to c) above.
Compacts according to the invention have the advantage of providing good side visibility, typically when the said compact is placed on a shell or on a display unit, because they have a surface R with a large laterally projected area SR, particularly by projection on a vertical plane V typically parallel to the said plane P.
FIGS. 1 to 5b relate to compacts (1) according to the invention,
In all FIGS. 1 to 8b, only essential compact topology elements in general have been shown, namely typically in the horizontal plane H, the bearing surface A and the support surface or polygon S, and in plane P, the centre of gravity G and the curve C.
The hinge (4) has been sometimes represented, but not the closer typically located on the opposite side of the hinge (4) so as to not put too much information in the figures. The said hinge has been diagrammatically shown by a rectangle shown in dashed lines in
a corresponds to
b shows surfaces E and R projected by the said compact (1) onto the horizontal plane H and the vertical plane V respectively. The compact is shown in dashed lines, the said compact (1) being similar to that shown in
a represents a diagrammatic view of a compact (1) in a plane perpendicular to plane P and to the said hinge, the said hinge (4) being parallel to the plane H and close to the said plane H. Another section through the compact is shown in dashed lines, the profile of the said compact (1) in the plane of the Figure perpendicular to the said plane P not being constant. In this Figure, the bottom (2) and the cover (3) are typically symmetric about the plane P.
b represents a diagrammatic sectional view of a compact (1) in a plane perpendicular to plane P, the hinge (4) not being perpendicular to this plane, and typically being parallel to this plane. In this Figure, the bottom and the cover are not symmetric with respect to the plane P.
a and 4b are perspective side views that illustrate two variant compacts (1) in which the said hinge (4), as in the case in
In
a corresponds to
b corresponds to
a to 6c are side views related to compacts (1′) according to the state of the art.
a illustrates the value of the angle αM in the case of a rectangular compact placed normally on a plane support H.
b illustrates the value of the angle αM in the case in which the same compact is placed on the edge, in other words abnormally since it is not very stable.
c illustrates the case of a compact with an oval profile, that can oscillate like a weeble but which always returns to its stable position.
a shows a perspective view of a compact (1) similar to that in
b is a perspective view of a compact (1) that is firstly in the form of a weeble, and secondly and independently has a curved plane P′ in substitution of the said plane P.
a and 8b are perspective views of a compact (1) with two adjacent parts forming an angle γ between them and comprising two planes P, one part with a plane P1 and a centre of gravity G1 and the other with a plane P2 and a centre of gravity G2.
The compact (1) according to
According to the invention, the said medium contact plane P and the said contour C may form an angle from the said support surface S, β=90°±25°.
The said angle β may be equal to 90°±5°, and is preferably equal to 900.
Thus, in
However, an angle of approximately 90° is necessary in
According to one variant of the invention and as illustrated in
In this case, the closer (5) typically opposite the hinge, is located at the upper part of the compact (1).
According to another variant of the invention and as illustrated in
According to another variant of the invention and as illustrated in
In compacts according to the invention, the said area SE may be greater than the said area SS, as typically illustrated in
As illustrated in
Although the invention does not require a predetermined shape for the said bearing surface A or the said support surface S, the said support surface S and/or the said bearing surface A may typically be a circle, or an ellipse, or a regular or irregular polygon.
For example,
As illustrated in
However, the said variable profile may reduce over a part of the height of the compact and then increase, without departing from the scope of the invention.
According to the invention, the said contour C may comprise or form a combination of a straight line and typically an arc of a circle or an arc of an ellipse or a broken line, so as to have a variable profile or section in a plane perpendicular to the said plane P.
The said curve C typically includes two parts, firstly a first part located in the plane P and secondly a second part closing the said first part, and typically in or close to the bearing surface A or the support surface S. In the figures, the said second part has been diagrammatically shown by a straight line in the support surface S—see
The said first part of the curve C that in particular contributes to giving its external shape to the said compact may be very variable and thus for example form a complex arc in
Thus, the shape of the curve C itself may be arbitrary, based on geometric criteria, to the extent that there is an infinite number of curves C with the same centre of gravity G.
According to the invention, the said height h of the compact (1) may typically vary from 40 mm to 70 mm, but heights of up to 100 mm are possible for large compacts, and heights as low as 30 mm are possible for small compacts.
Preferably, the said height h of the said compact (1) in the so-called “vertical” position is typically the largest dimension of the said compact.
This is usually advantageous; however, cases can arise in which the largest dimension of the compact is not its height h, particularly for some particular compacts.
Even if in theory a compact (1) may be placed in different manners on its plane support H, in practice there is only one way of placing it considering the decoration of the compacts and the graphics which cannot be read unless the compact is placed in a predetermined orientation, and therefore its vertical direction (13) is imposed.
In compacts according to the invention, the said bottom and the said cover may have plane or non-plane external surfaces. As in the case of the curve C, this applies to variants allowed by the invention within the context of a compact comprising the same basic topological data, namely the position of the centre of gravity G of the curve C with respect to the support surface S.

All Figures—except for
These compacts are typically made by moulding a bottom provided with hinge and closer elements, and moulding a cover provided with hinge and closer elements complementary to the corresponding elements on the bottom.
After bringing the hinge elements on the bottom and the cover to face each other, they are typically assembled by means of a central hinge pin.
According to one variant, the bottom includes a inner frame fixed to the said bottom, the said inner frame supporting the said hinge and/or closer element.
The compacts according to the invention have been used for packaging cosmetics such as an agglomerated powder, and in general for all so-called “solid” cosmetics that will not deform by gravity under the action of their own weight.
The invention has many advantages in practice. As illustrated as an example in the figures, the compacts according to the invention introduce a new topology that:
These are important advantages in the field of packaging cosmetics.
