     DETAILED DESCRIPTION OF THE INVENTION  
       [0015]     With reference to the drawings, a container according to the invention, generally indicated  1 , comprises a first half-shell and a second half-shell  2 ,  4 , generally made of injection-moulded or thermoformed plastics material.  
         [0016]     Although, in the drawings, the two half-shells have a configuration generally corresponding to that illustrated in WO93/00267, in which each half-shell has a rounded, dome-shaped end portion and an adjacent, generally cylindrical skirt portion, the constructional principle of the invention is intended to be applicable to half-shells of different configurations.  
         [0017]     The two half-shells can be coupled mouth to mouth by mutual engagement means constituted, for example, by a collar  6  which is carried by one of the half-shells and which can engage the mouth portion  8  of the other half-shell. To promote a firm connection between the two half-shells, form-fit or snap-engagement means are provided and are constituted, for example, by an annular rib  10  which engages a corresponding annular groove (not visible in the drawings) formed on the internal wall of the mouth portion of the other half-shell. It is intended that other engagement means may be used, provided that they are suitable for ensuring a connection which is firm but which can be released easily by the user.  
         [0018]     According to the principal characteristic of the invention, connection means are associated with each of the two half-shells and can engage one another in order to keep the two half-shells connected to one another even when the container is in the open configuration.  
         [0019]     Preferably, when the connection means are in mutual engagement, they are arranged and configured in a manner such as to permit a movement, with limited travel, of one half-shell relative to the other in a direction perpendicular to the plane of the mouth. Moreover, in their mutual engagement position, the connection means preferably perform the function of articulating one half-shell to the other so as to permit an opening pivoting movement of one half-shell relative to the other.  
         [0020]     In particular, the connection means may form a buckle-type connection with a male element  12  or  14  and a female element  16  or  18  which are capable of a mutual form-fit, snap-engagement, or friction coupling and which are integral with the half-shells  2  and  4 , respectively.  
         [0021]     In one embodiment, the connection means comprise a male element  12  which is integral with the half-shell  2  and which extends from the periphery of the mouth of that half-shell and a female element  16  which is integral with the other half-shell  4 . The male element  12 , which is made of flexible and resilient plastics material, is preferably articulated to the body of the half-shell  2  by a film hinge  20  and has a generally anchor-like configuration with anchoring ends  22   a ,  22   b  which are bent at an acute angle. The female element  16  is defined by a bridge-like wall  26  which is integral with the half-shell  4  and which extends adjacent the collar  6  so as to delimit a cavity  24  which is open at its longitudinal ends. The anchor-like element  12  can be fitted in the cavity  24  as a result of resilient deformation of the bent ends  22   a  and  22   b  which, after their insertion, can engage the side walls  28  and  30  of the cavity  24  by returning resiliently.  
         [0022]     Preferably, as shown in  FIGS. 1 and 2 , the male element is formed by a pair of parallel prongs  22  separated by a longitudinal slot  32  and each having an anchoring end  22   a  or  22   b . Correspondingly, the female element  16  comprises inside the cavity  24 , a guide rib  34  and a pair of projections or teeth  36  and  38  projecting from the side walls  28  and  30 , respectively. In this preferred embodiment, the male element can be fitted in the female element with the guide rib  34  engaging the slot  32 ; when the male element  12  is fitted in the female element, the projections  36  and  38  act as locking elements which engage the ends  22   a  and  22   b  so that removal of the male element from the female element and separation of the two half-shells thus connected are prevented.  
         [0023]     In any case, the connection is such that the male element  12  is movable inside the cavity  24 , parallel to the rib  34 , until the ends  22   a  and  22   b  engage the projections  36  and  38 ; it will be appreciated that this capability for movement in a direction perpendicular to the plane of the mouth facilitates the opening of the container from its closed configuration.  
         [0024]     In the embodiment of  FIG. 3 , the male element  14  is constituted by a flexible tab which may be articulated, to the body of the half-shell, optionally with a film hinge, (broken line  20   a  in  FIG. 3 ) and which has at its end a tooth or projection  40  which can be introduced into a bridge-like female element  18  integral with the half-shell  4 . When the tab  14  is inserted in the female element  18  until the tooth  40  has passed the side wall  54  of the bridge  18 , the tab  14  is movable, with a limited travel, in a direction perpendicular to the plane of the mouths of the two half-shells and its removal is prevented by the tooth  40  which comes into engagement with the side wall  54  of the bridge  18 .  
         [0025]     In the embodiments shown, the connection means form, in general, a permanent connection between the two half-shells, that is, a connection which is not easily releasable by the user, in particular, by a child.  
         [0026]     According to a further, optional characteristic of the invention, the container is provided with means which facilitate its opening. These means comprise a thin, flexible tab  42  ( FIG. 5 ) which is integral with the half-shell  4  and which is connected at  44 , optionally by a film hinge, to a portion of the periphery of the mouth of the collar  6  which is intended to be inserted inside the mouth of the half-shell  2 . In the closed configuration of the container, the tab  42  extends along the wall of the half-shell  4  with a portion  46  of its surface interposed between the wall of the collar  6  and a portion of the wall of the other half-shell  2 , adjacent the mouth. In  FIG. 5 , the chain line  48  illustrates the position in which the periphery of the mouth of the half-shell  2  is situated when it is associated with the half-shell  4  in the closure position.  
         [0027]     The container can easily be opened, starting from the closed configuration of  FIG. 4 , by gripping and lifting the end of the tab  42  in the direction of the arrow F of  FIG. 4 . This operation brings about disengagement of the mouth of the half-shell from the collar  6  of the half-shell  4 .  
         [0028]     Since, in the closed configuration of the container, the half-shell  2  is articulated to the other half-shell about the film hinge or bend line  20  or  20   a  which, in this configuration, is flush with a shoulder  50  of the collar  6 , the lifting of the tab  42  permits an opening pivoting movement of the half-shell  2  relative to the half-shell  4 . Moreover, since, even in the mutual engagement position, the connection means between the two half-shells permit movement of the half-shell  2  relative to the half-shell  4  in the direction perpendicular to the plane of the mouth with a travel almost corresponding to the depth of the collar  6  or, rather, corresponding to the distance between the shoulder  50  and the engagement rib  10  of the collar, the opening of the container to permit removal of the articles contained therein is further facilitated.  
         [0029]     A band  52  formed by a film of heat-shrinkable plastics material may advantageously be associated with the closed container, so as to surround the joining region between the two half-shells and to be superimposed on the connection means  12  and  16  or  14  and  18  and at least partially superimposed on the tab  42 , when a tab  42  is present. The band has the function of further ensuring the anchorage between the two half-shells of the container and may also be used to receive informative printed inscriptions, avoiding the use of an explanatory slip inside the container.  
         [0030]     By virtue of the characteristics described above, the container according to the invention is more compact and manageable and can easily be controlled and handled by the user.  
         [0031]     It is intended that, the principal of the invention remaining the same, the forms of embodiment and details of construction may be varied widely with respect to those described and illustrated, without departing from the scope of the appended claims. Thus, for example, it is intended that other connection means which achieve the same functional capabilities described above may advantageously be used.  
         [0032]     Similarly, the shape of the container and of the two half-shells described above with reference to the configuration described in WO93/00267 may be varied to include other shapes such as, for example, a generally egg-shaped configuration formed by two half-shells coupled in an equatorial plane or by two half-shells coupled in a meridian plane of the container.  
         [0033]     Moreover, the term half-shell, as used in this description is not intended to be limited to half-shells with marked concavity and having a containing function but is also intended to include the situation in which at least one of the two half-shells is of generally flattened shape, performing substantially the function of a cover for the other half-shell.
