Such a handle or handle is more particularly suitable in the case where the packaging 1 is bulky and heavy (for example if the capacity is of the order of 5 liters).
• FIGS. 6 to 8 illustrate the canister 2.
• This canister 2 is, in the embodiment considered, made of high density polyethylene. Its constituent wall is thinned, except in the region of the neck 3 and the opening 4. For example and for a capacity of the order of a liter or a liter and a half, the thickness can be of the order of 3 / 10 mm instead of 8/10 mm as is usually the case for this kind of container.
• the wall constituting the container is not completely flexible as would be a completely flexible pocket. This wall of the container 2 is substantially deformable under the action of external constraints of manual gripping.
• the user grasping only the container 2 only the latter is, by the pressure exerted on him, deformed and its constituent walls 13, 14, themselves deformed then return to their original state resulting from the conformation initial when the pressure exerted is moderate. If the pressure exerted is significant, the can 2 can be folded or crushed which is advantageous when it must be discarded after use.
• the lower limit of the thickness of the wall constituting the container 2 is defined by the manufacturing constraints and by the fact that the container 2 must as a whole have the cylindrical or prismatic conformation illustrated in the drawings.
• the container 2 must also be capable of receiving the. content. However, the container 2 is intended to be used in combination with the outer envelope 6 which acts as a support and protection.
• stiffening grooves 16 elongated substantially axially on the front walls 13 and stiffening grooves 17 elongated orthogonally to the axis 7 located on the side walls 14 as well as on the first end 8 and the bottom 9.
• These grooves are preferably essentially hollow so that the container 2 laterally offers a large friction surface with the outer casing 6 capable of ensuring proper maintenance.
• These grooves are also and primarily intended to facilitate the extraction of the container 2 during its manufacture.
• the wall of the container 2 is relatively thickened and substantially undeformable under the action of external constraints of manual gripping or blocking in the region of the neck 3 and the opening 4.
• can 2 can have the usual thickness for this kind of can.
• the neck 3 then comprising an external thread with which an internal thread can cooperate complementary to the screw-on plug 5, it should be understood that other forms of plugging can be envisaged, the neck 3 then comprising suitable external protrusions with which complementary protrusions adapted from plugging 5 can cooperate.
• the closure 5 is in itself devoid of tamper-evident means. It can therefore be a fairly simple conventional stopper. Inviolability is then achieved by the outer envelope 6 in the non-fractured state, the latter substantially enveloping the closure 5.
• the neck 3 is located eccentric laterally and a side wall 14 (in this case the left wall in the figures).
• the axis 18 of the neck is inclined relative to the axis 7 for example with an angle of the order of 30 °.
• the container 2 provided with its closure 5 is such that the closure 5 does not exceed and even is substantially tangent to the plane Q extending the wall 14 on the left side where is located the plugging 5 which allows a suitable wrapping of the plugging 5 by the outer envelope 6 as already indicated.
• the packaging 1 may include complementary members associated with the neck 3, with the opening 4, with the stopper 5 with a view to dosing the content, ensuring drop by drop pouring, etc.
• the tightening of the inner container 2 by the outer envelope 6 is effective with the container 2 empty of its content but, even more, when the container 2 (therefore the packaging 1) is filled with its content.
• the dimensions of the can 2 and of the envelope exterior 6 are defined one according to the others.
• the friction between the can 2 and the outer casing 6 essentially maintains the can 2 in the outer casing 6, without the need for additional positive means of maintenance or association.
• the container 2 is not glued, welded, crimped to the outer envelope 6.
• the packaging 1 has been emptied of its contents, to completely dissociate the packaging in two parts namely on the one hand the container 2 and on the other hand the outer casing 6. These two parts can be treated separately by the user in two separate specific bins. It should be noted that the can 2 being then empty, the sliding of dissociation is made easier. In the case of the second variant, the tightening and the friction participate in maintaining the container 2 in the casing 6, but there are additional means of maintenance described later.
• the internal container 2 is held in the external envelope 6 without means other than the conformation of the external envelope 6.
• This conformation, this tightening, this friction can be facilitated by the presence, on the outer casing 6 of pre-folding lines or grooves 19 in particular parallel and spaced from the edges 15 as well as from the edges of the base 11 and the top 12.
• pre-folding lines or grooves 19 allow slight ovalization of the outer casing 6 facilitating its manual gripping by the user.
• the packaging 1 comprises, on the outer envelope 6 at least when the latter is in the non-fractured state, at least one opening 20 located at the near the blockage 5 and allowing at least partial vision thereof without, however, allowing its natural removal.
• at least partial vision is meant the fact that an outside observer clearly identifies, by simple vision through the opening 20, the presence of a blockage 5. This arrangement allows the observer to avoid any misunderstanding on nature of the packaging l. In fact, the wrapping of the container 2 and the plugging 5 by the outer envelope 6 might not allow the outside observer to realize that the packaging 1 is of the type comprising an opening, a neck, and a plugging.
• the expression “not allowing natural removal of plugging 5” is understood to mean the fact that plugging 5 cannot be removed in order to open the opening 4 except for deliberate,ticianist maneuvering requiring a complicated position of the hand or fingers or even a particular tool.
• the opening 20 therefore has a relative size and location relative to the stopper 5 so as not to naturally allow the uncorking maneuver.
• the opening 20 is for example offset with respect to the stopper 5 (FIG. 1) or even much smaller than the stopper 5 (FIG. 1 and FIG. 13) or again offset with respect to the direction of removal of the stopper 5 (FIG. 1, Figure 11 and Figure 13).

This region must be fractured to pass from the non-fractured state to the state of possible use. This fracturing requires a voluntary act by the user. Even if this fracture is unexpected or untimely, it is visible.
• the region 23 includes or is limited by at least one line or groove for breaking, cutting, less resistance 25. It follows that there is a movable or displaceable part of the rest of the outer envelope 6 which remains, it, associated with the can 2 ( Figure 2).
