Summary of the invention

The invention provides a molded element of closure according to claim 1.

In a preferred embodiment of the invention, the tray is rectangular and has a main central body, walls opposite rectangular sides and opposite end walls rectangular. Preferably, the lid is a cardboard material or plastic that forms in three parts providing two slots parallel. A base panel underlies the tray and is glued or otherwise connected to the bottom of the tray. A panel Loin covers one end of the tray, and a cover panel covers the top of the tray. The lid panel can be folded by a free end and laminated to provide a lid relatively rigid Alternatively, a second one can be laminated. layer inside the lid panel to provide stiffness and also to provide supports for the protected content of the container.

In a preferred embodiment, the tray is molds in a mold cavity to produce three parts: a body main, a sliding slip band and a hinged flap of closing. The main body has at one end a part of shelf with a central opening through which a extension of the closing flap. An opening similar near the free end of the lid panel also receives the hitch extension. The lid panel is held above the shelf by the extension of the coupling that extends through from the opening of the lid panel and through the opening in the shelf on one end of the main body.

The closing flap is connected the body main by a live hinge on a top edge out from One end of the body. The working band is formed within a central opening in the body and is connected to the body Main by flexible bands. The work band is molded in one position and moves to an operational position. Nail extensions of the working band and some extensions of the main body are attached respectively to adjacent pieces of the main body and the band to allow sliding. Flexible bands allow movement of the working band up to an operational position and function as a spring mechanism over the center to lift the lock band to the position of total work. In that position of total work, a projection of lock at one end of the lock band engages the extension of the hitch and prevents the flap from opening closing.

To release the extension hitch, it move a pull ring at an opposite end of the band of work in one direction away from the work position. Some stops prevent excessive movement in the opening direction. He movement of the working band towards the position of unlocking releases the closing flap for opening. The bands flexible return the working band to the working position when the shooting ring is released.

After the closing flap has been open, the free end of the lid panel is lifted. Panel lid is hinged around the far end of the tray. Lifting the free end takes off the side edges of the panel cover from under the inward projections on the sides of the tray. Opening the cover panel provides access to the content inside the bowl

The lid is then returned to the position closed. Push down on a center of the lid panel folds the elastic cover around a longitudinal axis, allowing the edges of the lid panel to fit under low pressure the projections inward on the extended sides upwards of the tray. The closing flap is then closed on the lid. He protrusion hitch extension extends through the opening in the lid and of the opening aligned in the part of shelf of the tray. The hitch extension protrusion has a outwardly inclined surface that engages a surface inclined cam on the top of the projection, pushing the locking boss and the closing band away from the closing position so that the extension projection of hitch can snap under the locking boss. The flexible bands return the working band and the projection of lock to the lock position, and the container is protected against an unintended opening.

The opening of the container requires a movement of the work band, sliding the pull ring into the oval openings aligned on the tray and on the base panel of the lid, while the closing flap is raised.

In a preferred form, the closure flap is formed with parallel grooves that extend perpendicularly from positions spaced from the live hinge to the edge Opposite free of the closing flap. The slits divide the closing flap in three sections. A central section has a opening through which the projection of hitch extension. Two outer sections have some vaulted parts that have raised free edges of the outer sections. The raised edges open towards the end opposite of the container. Insert the fingers longitudinally under the raised edges and vaulted parts while the pull ring on the other side of the container is moving away from the position of closure raises the outer sections of the closure flap. He slippage of the working band releases the projection of hitch extension and allows to raise the central section of the closing flap. The elevation of both outer sections of the closing flap causes the central section to rise closing flap and lifting extension hitch away from the coupling position with the locking projection. In one embodiment of the invention, the lifting of both outer sections to provide enough torque of torsion in the areas at the end of the grooves to lift the central section

With reference to figure 1, a container of Closure for storing pills or other objects is usually indicated by number 1. The container has a tray 3 rectangular, molded, plastic, with 5 sides and 7 sides, Opposites, rectangular. Elongated flanges 9 extend inwards from upper edges of sides 5 and 7. The flanges hold side edges of a cover panel 11. The lid is formed as a rigid section of an enclosure 25 of Laminated plastic or cardboard material folded and folded.

A closing flap 13 holds one end of the cover panel 11. The closing flap is connected to an edge upper of a longitudinal end 14 of the tray 3 by a hinge 15 alive. The closing flap has a central section 17 operational and two lateral sections 19. The central section has a hitch extension. The side sections have parts 21 high curves, under which the tips of two can be inserted fingers to lift the entire flap 13. The central section 17 and the two lateral sections 19 are separated by slots 23. The grooves prevent the elevation of the central section 17 by lifting only one of the lateral sections 19. The slots are spaced through areas 22 of the edge 24 of the flap 13. Lift simultaneously from both side sections 19 transmits enough force through zones 22 connected to central section 17 to turn the center section up. Once the section 17 center has been lifted, the cover panel 11 can be turned towards above to expose the contents of the box. To the check the lengths of the slits 23 and the zones 22, the closure flap can be designed so that a zone 22 transmits a sufficient torque to lift the central section 17 when only a lateral section 19 is lifted. In one embodiment, as shown in figures 1 and 2, the cover panel 11 is part of a sheet 25 of surrounding sheet material surrounding and encloses the top, the bottom and an extreme wall of the tray. The sheet material 25 has a fold 26 at one end of the cover panel 11 which provides an extreme part 27 of loin.

As shown in the perspective view from below of figure 2, the sheet material 25 has a panel 29 butt that is connected to the extreme part 27 of loin along of the fold 28. The rear panel is attached, attached or attached physically otherwise to the bottom of tray 3. Some side edges of the rear panel 29 are protected by extensions down the sides 5 and 7 of the tray. The sheet of sheet material completely covers the top and the bottom and a longitudinal end 16 of the tray when The lid is closed.

Alternatively, the rear panel 29 and the panel Cap 11 can be manufactured separately. In that embodiment, the rear panel 29 is mechanically attached, bonded or adhered to the back of tray 3. Loin part 27 of the lid is connected similarly to the spine end 16 of the tray, and the cover panel 11 is hinged to the spine part 27.

A cut 31 is made on the rear panel 29 oval. A pull ring 33 is mounted on the tray and is placed inside the cut. The ring 33 can move from one end of the cut 31 to the other end. As shown in figure 2, the pull ring is in locked position 32, which prevents the flap 13 and the cover panel 11 from opening. In use, the pull ring is in the locked position unless it is intentionally move to a unlocked position.

As shown in Figures 3 and 4, the closing flap 13 has been raised to allow the opening of the cover panel 11. The inside of the lid 11 has multiple blisters 35 tablet retention. When the closing flap 13 is lifts, as shown in figure 3, the cover 11 can stand up to provide access to receptacles 35 of pills Blisters 35, adjacent wall or joints are frangibles to remove a pill by fracturing one of the blisters, their edges or an adjoining area of panel 11 of top.

A detail in section is shown in figure 4 transverse of the end of the closure flap of the container. The closure flap 13 is connected with a hinge 15 live to the edge 37 outside of an extension 39 out along the top of end 14 of tray 3.

As shown in figure 4, tray 3 It has a raised shelf 41 along the end 14 of the tray. The shelf has a rectangular opening 43 elongated, shaped funnel, with an inclined guide part 45 and a neck 47 narrowed

The closing flap 13 has an extension 51 U-shaped hitch, with side pins 53 extend perpendicularly from the central section 17 of the flap 13 closure. Extension 51 of U-shaped hitch it has a transverse hitch 55 that extends between ends of the perpendicular pins 53. The outgoing 55 of hitch has an inclined surface 56. An opening 57, to through which the hitch extension 51 is formed, is centered on the flap 13 of closure.

The cover panel 11 has a rectangular cut 59 which aligns with and covers the opening 43 on the shelf 41 to receive the hitch extension 51 when the closing flap 13 is close over the free end 60 of the lid panel.

To keep the closing flap closed on the free end 60 of the lid panel, tray 3 has a band 61 slip of work. A vertical part 63 at one end of the work band supports a shoulder 65 of work. The band 61 of work, its part 63 raised and the shoulder 65 of work they are mobile from right to left, as shown in the figure 4, by the movement of the ring 33, as shown in figure 2.

The projection 65 of lock locks the projection 55 extension hitch when the fastening band and the outgoing lock are in the left position and releases the hitch extension 55 overhang when band 61 of trabadura and the projection 65 of trabadura move to the right, as shown in figure 4. In the locked position, the locking projection 65 covers the transverse projection 55 of coupling that extends between the two pins 53 of the hitch extension 51.

As shown in Figure 5, the band 61 closing moves to the right, as shown by the arrow 66. The protrusion 65 of lock releases the protrusion 55 of hitch extension, and closing flap 13 can get free.

The shelf 41 has a horizontal projection with a extension 67 down that stops surface 69 of the part 63 raised from the working band 61. This prevents a withdrawal excessive working band 61 beyond position unlocked, as shown in figure 5.

Figure 5 also shows the blister 35 formed from an inner layer 71 of the cover panel 11. Layer 71 The inside of the cover panel 11 is bent at the free end 60 and is attached to the outer layer 73 of the lid. Figure 5 shows also one of the flanges 9 that extends inwards that cover the edges of the lid and hold the edges of the lid panel down until the lid panel is intentionally lifted at the end 60 free. Lifting the free end 60 takes off the edges of the lid panel below the flanges 9 as the lid panel rises. When panel 11 is raised and lowered lid, the lid acquires a slight curvature or buckling that takes off the edges under the flanges during lifting and fits to press the edges of the lid beyond the extensions 9 of Flange in when the lid panel is closed.

Figure 6 shows the moved working band totally left in the direction of arrow 68, so that the projection 65 of lock is directly under the opening 43 on shelf 41. Initially, the cover panel 11 closes pressing down on the center of the lid panel to place the side edges of the cover panel under the flanges 9 that extend towards opposite side walls. So, the closing flap 13 is closed by pressing, in the direction of the arrow 70, in the central section 17 of the closing flap. The inclined surface 56 of the engagement boss 55 can be engaged to the inclined surface 45 of the rectangular opening 43 in the shelf 41 to center the extension 51 of engagement. A force continuous downward causes the inclined surface 56 to engage the inclined surface 71 on the projection 65 of the lock, which slide the projection 65 of working, part 63, to the right raised and the working band 61 in the direction of arrow 66. This allows the transverse hitch 55 to engage pressure under the projection 65 of lock and allows the hitch extension 51 is fully inserted under shelf 41. As soon as the transverse hitch 55 slides off under the horizontal surface 73 of the projection 65 of the lock, the vertical part 63 of the shoulder boss and the band 61 of lock move to the left, in the direction of arrow 68, to lock the protrusion hitch extension 55 and the flap 13 closing in place, securing the lid. The band 61 of lock moves until the protrusion 55 extending hitch is under projection 65 of lock.

As shown in Figure 7, the band 61 of trabadura and the projection 65 of trabadura are in the position locked. Preferably, the return of the working band 61 to the locked position is carried out with a spring. Preferably, it They use flexible band leaf springs.

Figures 8 to 10 show tray 3 in the molded position Tray 3, closing flap 13 and the band 61 lock are formed from plastic in a cavity Individual mold with limited lateral actions.

Figure 8 is a perspective view from above. Tray 3 has a main body 81 with cuts 83 that They save material and lighten the product. A body sections 85 central surround the central edges 87 inwardly oriented, the elongated central opening 86 and oval opening 88. A few rebates 89 at the edges 87 allow the formation of a rod 91 transverse, which is molded entirely with the band 61 of trabadura A few lateral recesses 93 on the lateral walls 95 of the working band allows a slight flexion in the area of the transverse rod to allow sliding, in the direction of the arrows 97, towards the locked position 99 of the rod 91 transverse, shown in dashed lines. A few rebates 101 in the side walls 95 of the lock band 61 allow the formation of guides 103. Guides 103 are fully formed with the central body sections 85. The guides 103 are extend inward from the intermediate walls 87 of the body sections The guides have 105 thick edges and some 107 thin parts. The thin portions 107 form surfaces on which lateral areas 109 of the band 61 slide trabadura

The front end of the working band 61 the end element 63 is completely formed therein perpendicular to the projection 65 of trabadura. Surface 71 inclined of the protrusion of work is used to facilitate the assembly of the lock band 61 in the use position, as well as to help in the work of work. The extreme element 63 perpendicular is connected laterally to bands 111 flexible having ends 113 connected to sides 115 of the extreme structure, as shown in figure 9.

The shelf 41 has lateral sections 117 elevated and a central section 119. The lower sections 121 Tray 3 ends are attached to the front wall 14 extreme At the opposite end 16 two walls 123 and 125 extend vertical between the side walls 5 and 7.

After molding tray 3, ring 33 of shot can be used to move the band 61 of lock to the right, as shown in the bottom view of figure 9. The inclined surface 7 on the shoulder projection 65 will push against surface 131 inclined at prominence 133 of the central section 119 that forms the shelf 41, allowing the projection 65 of lock and vertical section 63 pass under the prominence 133 on the shelf. The cooperating surfaces 67 and 69, as shown in figure 5, prevent the return of the band of working beyond prominence 133.

When the ring 33 pulls the band of right lock to the operating position, the lower surfaces 141 of transverse rod 91 slide on the upper surfaces of the internal parts 85 of the tray body Areas 109 of the upper lateral surface in the working band 61 they slide under the surfaces 143 bottom of the thin parts 107 of the extensions 103. A thick 105 edges provide 145 ends to prevent overcarrera of the band 61 of trabadura in the sense of trabadura

Near end 14, shelf part 41 has vertical walls 147 that hold the shelf near the opening 43. Ends 149 may collide with flexible bands 111 and avoid the overhang of the projection 65 of working in the sense of trabadura Sloped walls 151 allow bands 111 flexible extend, bend or arch.

Figure 10 shows a top view of the 3 preferred tray in molded position. Highlights are added 153 of reinforcement to the flexible bands 111, and parts 155 and 157 They get thinner near the ends of the bands. The highlights 153 avoid the axial warping of the bands, and the edges and parts 155 and 157 slimming enhance controlled bending with forces Reasonable applied.

As shown in Figures 9 and 10, the edges of the tray 3, the closing flap 13 and the lock band 61 formed in full are curved to provide additional strength, to prevent breakage and to provide comfort to the user when runs into surfaces
put on

Figure 11 is an enlarged view detail from below showing the closing flap 13 and the extension 51 of hitch in the closed position. When the 61st band of work moves to the locked position, the projection 65 of lock prevents the opening of the closing flap engaging the boss 55 transverse in hitch extension 51.

Figure 11, a view from below, shows also in more detail the prominence 133 of retention with the inclined wall 131 of the assembly and retaining wall 67. The working band 61 has a central recess 161 opposite the piece 91 transverse to reduce material and weight and to enhance flexibility.

Figure 12 is a detail view from above. similar to the detail view from below shown in Figure 11 with the closing flap 13 closed. The closing flap 13 is divided by slits 23 in outer sections 19 and a section 17 central. If any of the outer sections 19 on the right or the left of the central section 17 rises without raising the another extreme section 19, a force is not sufficiently transferred from lifting to the central section. This is especially the case. if the working band has not been retracted. The slits 23 can be shortened so that lifting one side 15 elevates the section central.

Figure 13 is a detail of a view in cross section similar to figure 11, showing the flap 13 closed closure and extension 51 of section hitch 17 central extending through opening 43 in part 41 of shelf shelf. The working band 61 has not slipped still up to the operating position.

As shown in Figures 11 and 13, the transverse element 91 of the lock band 61 is lowered 161 to provide a reduction in weight and material while the rigidity of the transverse element 91 is maintained. For the same reason, the thick parts 105 are limited to edges that extend around the thin portions 107 of the guides 103 to maintain the rigidity of the guides, while reducing the material and the weight. The pins 53 of the extension 51 of engagement are relatively wide to provide stiffness and strength in the extension 51. Side edges 163 of the pins 53 are tapered to provide strength, lightness and alignment in the opening 43.

Figure 14 shows a bottom view of the tray 3, with the closing flap 13 and the extension 51 of hitch extending through opening 43 on shelf 41. The lock band 61 has moved to the position of trabadura, in which the projection 65 of trabadura covers the projection 55 hitch extension 51 hitch. The surfaces 141 lower of the transverse member 91 have slid to the position 99 above the internal part 85 of the tray body 81. The upper surfaces of the edge portions 109 of the band 61 They have slipped under the thin parts of the guides 103. Flexible bands 111 have moved beyond the center to its operational position.

Figures 15 and 16 are details of view from under the tray with the closing flap 13 closed and the hitch extension 51 extending through the opening 43. In the detail of Figure 15, the working band 61 is shows in its molded position. In Figure 16, the detail shows the lock band 61 in the lock or use position toward in front of.

Figures 17 and 18 are perspective views from above and below, respectively, of tray 3 with the closing flap 13 in the closed position and band 61 of lock moved to the working position of lock. The flexible bands 111 hold the lock band 61 in the working position and return the working band 61 to the lock position when the 33 ring is released after of opening the container.

Figure 19 shows the ring 33 of moved shot towards the center of the oval opening 88, unhooking the projection 65 lock the extension 51 hitch and releasing the closure flap 13, which has been raised to release a panel 11 of top. When the ring 33 is released, bands 111 flexible return band 61 to the position of trabadura

Figure 20 is a perspective view from above the tray 3 in which the firing ring 33 has been released and flexible bands 111 have moved the lock band 61 to the working position. The closing flap 13 has been closed and insured.

Figure 21 is a longitudinal view in cross-sectional perspective of the container in which the closing flap 13 has been closed on the free end 60 of the cover panel 11. Engagement extension 51 extends to through opening 59 in the lid panel and opening 43 in the shelf 41. The projection 65 of lock is placed on the transverse hitch 55 of extension hitch 51 of hooking, avoiding the opening of the closing flap 13 until shot ring 33 slide to the right. The 33 ring it is exposed through the large oval opening 31 on the panel 29 base lid and oval opening 88 aligned on the tray 3. The ampoules 35 contain the products that are stored in the locked container

Figure 22 is a detail of the flap 13 of closure that keeps the lid panel 11 closed and the projection 65 of lock that prevents the opening of the closing flap. The stops 67 and 69 avoid the overcrowding of band 61 of work in the sense of unlocking.

The pull ring 33 can be handled and the flap Closing 13 can be opened by placing the thumbs under both longitudinal ends of the container and placing the fingers on top of the container. A thumb, for example, the right thumb, makes run ring 33. The index and ring fingers of the other hand, for example, the left hand, may be bent with the tips of those fingers under domes 21 in sections 19 outer flap 13 closure. Once the flap 13 of closure has been raised, ring 33 can be released, and the hand right can be used to raise the cover panel 11. Raise the lid panel lifting the free end 60 takes off the edges of the cover panel from under the extensions 9 inwards.
