Description

Cursor for a lockable fastener repeatedly that It rests in a two-dimensional plane.

Field of the Invention

The invention relates to cursors that apply repeatedly opening or closing forces to fasteners, especially rigid, elongated and lockable fasteners repeatedly, resting on a plane that defines X and Y directions mutually orthogonal

Background

Flexible use storage bags for the containment and protection of various items, as well as for the conservation of perishable materials as articles food, are well known in the art. Typically, said bags comprise an elongated fastener repeatedly closable, as a shaped rib interlock gasket integrally with the bag, to tightly close the contents arranged in the bag. Closing mechanisms sliders that use a plastic sliding sleeve to favor the engagement and disengagement of interlocking ribs they have become very popular because their operation is relatively simple and allow to confirm with sight and touch that the gasket formed by the loosely fastener has repeatedly completed successfully.

Rigid and semi-rigid containers also They are well known in the art. These vessels have achieved a fair degree of commercial success by providing a means to Store a wide variety of content. Typically, these containers incorporate lids that are normally sealed to the container by means of a lockable fastener repeatedly comprising convex or concave interlocking elements, such as bulges or clefts Additionally, the patent 3,784,055, issued January 8, 1974 to Anderson, and US-3,967,756, issued on 6 from July 1976 to Barish, both incorporated as a reference in the This report describes containers that use closures seals

Although said mechanical closures can be effective to preserve the contents of containers, some consumers experience difficulties to fully complete the closing operation and confirm for themselves that a satisfactory closure. This happens especially when the change physical position of the lid between the interlocked positions and not Nestled is relatively small.

Traditional cursors that are used with repeatedly fasteners in flexible bags of Storage guarantees the user that the fixer opens or closes during use; however, these cursors incorporate typical side walls that limit its operation to fixers unidirectional. US-3,660,875, issued on May 9, 1972 to Gutman, illustrates an example of a cursor of traditional type. The BE-505.325 patent granted to Prouvost, illustrates the use of a hermetic flexible zipper in a storage bag to contain tissue scraps. Given the rigid and semi-rigid containers typically incorporate covers sealed by fasteners that extend in directions that have vector components that extend in directions mutually orthogonal, traditional cursors are not suitable to open or close said fasteners. The zipper gasket of Prouvost would require considerable flexibility in the components attached so that said zipper could circumscribe a container repeatedly rigid rigid or semi-rigid multidimensional. The Prouvost gasket does not apply a sealing force in a Z direction when it crosses a trajectory in the plane X-Y.

Therefore, it is desirable to provide a cursor to open or close a lockable fastener repeatedly to close tightly a lid to a storage container in which the lockable fastener repeatedly rests in a two-dimensional plane that defines mutually orthogonal directions. Especially, it is desirable to provide a cursor that can be joined so Slidable to the lockable fastener repeatedly and that can open and effectively close the fastener and pivot around corners that join mutually orthogonal sections or curvilinear segments of the fixative. More especially, it is desirable to provide a cursor that has the mentioned attributes and that can open and effectively close the lockable fastener repeatedly so that, apart from moving the cursor along the fixer, the maneuver that The consumer must be minimal.

Summary of the invention

A cursor opens or closes an elongated fastener repeatedly that rests in an XY plane and can be sealed in a Z direction orthogonal to the cursor. The cursor can be slidably attached to the fixator and transmits forces to the fixator in the Z direction to open or close it as the cursor moves along a travel path that has vector components in the X and Y directions. The cursor it favors that interlocking elements of the lockable fastener are repeatedly engaged operatively associated thereto as the cursor moves in a first direction along the travel path and causes the interlocking elements to separate when the cursor moves along the path in a second direction that is opposite the first
address.

In one embodiment, a wedge arranged on the cursor favors that the elements of locking of the fastener as the cursor moves in the first direction and causes the elements to separate when the cursor is Move in the second direction. In an alternative embodiment, a wedge causes the interlocking elements to be separated according to the cursor moves in the second direction while other parts of the cursor have a separation from each other that is sufficiently small to join the fastener elements as the cursor moves in the first direction.

Description

Here, the following terms They have the following meanings:

X, Y, and Z are coordinates that define directions perpendicular that cut each other forming right angles in a origin.

Rigid means with scarcity or devoid of flexibility; with a consistent and indeformable appearance, which does not changes when typical forces of use are applied.

A lockable fixative is repeatedly a fixative that can selectively be opened, hermetically sealed, back to open and close tightly.

The present invention relates to a cursor suitable for opening or closing an elongated lockable fastener repeatedly. Although the cursor of the present invention can be apply to open all kinds of locks fasteners repeatedly which are used to hermetically seal flexible bags of storage, tubs or other storage containers, It is especially suitable for opening or closing fasteners rigid, elongated, repeatedly closable resting on a plane X-Y that requires the cursor to travel a path that has vector components in the X and e directions Y. More especially, the cursor of the present invention is suitable to open or close a rigid, elongated, lockable fixator repeatedly that rests on an X-Y plane and you can tightly close in an orthogonal Z direction to it, where the cursor transmits forces to the fixator in the Z direction to open or close it as the cursor moves along the travel path An example of said lockable fixative repeatedly it is a fixator that tightly closes a lid 30 at edge 20 of a storage container 10, as shown by the Figure 1.

The container 10 according to the present invention it can be relatively small, so that the container 10 It can be stored in a pocket or purse. Said container 10 It can be useful for storing pills, capsules, etc. So alternatively, the container 10 may be relatively large, of so that the container 10 is sized to fit in a Tractor truck with semi-trailer. Said container 10 may be useful. to transport building materials, etc. One of the uses contemplated of the container 10 is to store perishable items, I eat food

In the embodiment depicted in Figure 1, the storage container 10 includes a container body 12 which can be formed unitarily by a piece of material in foil, a flat or dome-shaped bottom side 14 that defines an X-Y plane, an opening 16 in the part opposite the lower side 14, an edge 20 circumscribing the opening 16 and a cover 30 to cover the opening 16. Both the edge 20 as the lid 30 are shown as flat, but can be shaped concave or convex with respect to the lower side 14.

Although the body of the container 12 shown has 4 side walls, the body can really comprise three or more side walls. In addition, although the opening 16 of the container shown in Figure 1 is arranged opposite the bottom side 14, the invention is applicable to openings 16 arranged in any container side

The edge 20 may be formed so unitary with the body of the container 12 or constitute an element of different material attached to the body of the container 12. When it comes of a different element, preferably of more rigid material, is it prefers that the material of the body of the container 12 forms at least a small peripheral edge 20 at its upper edge (which defines the opening 16) and be folded in the corners so that it forms a fitting point suitable for joining the body of the container 12 and the edge 20. The lid 30 may be formed unitarily with the container body 12 or be joined at least in an articulated manner to the edge 20 in a hinge line 25. The hinge line 25 can understand a single living hinge or be arranged as a line of weakness through grooving, perforations or the like, optionally, it can allow the lid 30 to separate from the body of the container 12. Although an embodiment with hinges is shown, the embodiments without hinges are also contemplated.

The lockable fastener 40 can repeatedly circumscribe or partially enclose the opening 16 of the container. The lockable fastener 40 can repeatedly comprise any type reusable mechanical seal known in the art. Together Suitable include friction or finned lace fin joints compression, adhesive joints, cohesive and adhesive joints selectively activatable as patents show US 5,662,758, issued October 2, 1997 to Hamilton et al .; US 5,871,067, issued on 16 February 1999 to Hamilton et al .; Application No. 08 / 745,339, filed on November 8, 1996 by McGuire et al .; and the Application No. 08 / 745,340, filed on November 8, 1996 by Hamilton et al., Incorporated herein by reference memory. Reusable means that the lid 30 of the container 10 can be reversibly changed from the open position to the closed position at least twice and continues to close Hermetically tightly the container 10.

In the embodiment shown in Figure 1, the fixative fastener 40 repeatedly comprises mechanical elements of interlocking 42 and 44 that include at least one convex element 42 which interlocks at least with a concave element 44 to form a meeting. The two interlocking elements 42 and 44 circumscribe the opening 16 of the container, occupying a marginal part of the lid 30 and a marginal part of the edge 20. The interlocking elements 42 and 44 are preferably separated from the peripheral edge of the cover 30 and the edge 20 at a basically constant distance inward, so that a cursor 100 with an interior extension suitable can be displaced along the peripheral edge without leave gaps or parts unsealed.

As Figures 2a and 2b show, the element convex 42 can be bulky and concave element 44 can be a recess 49 in a manner complementary to the convex element 42. The interlocking elements 42 and 44 are arranged in portions. in contact with the edge 20 and the cover 30. The convex element 42 it can be unitarily shaped with the edge 20 that is extends upward from the upper side 22 of the edge 20, while the concave element 44 may be shaped so uniform with the lid 30 which has a bulky surface without interlock 47 extending upward from the upper side 32 of cover 30 or vice versa. The concave element 44 is open in the lower side 34 of the cover 30 to receive the element convex 42 inside, while convex element 42 is open on the bottom side 24 of the edge 20.

The cursor 100 shown in Figure 1 is generally C-shaped, with cursor ends 100 overlapping on peripheral edges of edge 20 and cover 30, in overlying relationship so that parts of cursor 100 can interact with interlocking elements 42 and 44 of the fastener 40 repeatedly closable. A part of the cursor 100 that interacts with interlocking elements 42 and 44 it has a separation with the same that is small enough to favor that elements engage each other when the cursor 100 is subjected to a translation in a first direction over a region of the periphery where the elements are separated. Other parts of cursor 100 separate the interlocking elements 42 and 44 according to the cursor 100 moves in a second direction opposite to the first direction, applying separating forces.

The lockable fastener 40 can repeatedly define a continuous path path that has components of vector in the X and Y directions and extend from one end open 50 to a closed end 52 to direct the movement of the cursor 100 along the fixator 40. Alternatively, according to Figure 1 shows, a track 46 can be arranged along a side of the fixator that defines the continuous path of travel 48.

The path 48 may comprise a combination of rectilinear sectors that run in directions mutually perpendicular, with a sector that basically runs parallel to the X direction and an adjacent sector that runs basically parallel to the Y direction. The sectors are joined by a transition region that can comprise an arc that has a radius of curvature and a perimeter that has points of tangency with vector components of the X and Y directions. The trajectory of tour 48 can also be completely curvilinear with a oval shape or comprise a series of arched sectors that form a path with a wavy pattern as a shape sinusoidal.

Figures 3 and 4 show top views of the storage container 10 shown in Figure 1. The track 46 is congruent with the fixative 40 repeatedly lockable at along all the edges of the cover 30 and the edge 20, except in the edge occupied by the hinge line 25. Track 46 part of one side of the hinge line 25 comprising an open end 50 of the fixator to the other side of the hinge line 25 which It comprises a closed end 52.

In the configuration shown in Figures 3 and 4, track 46 defines a travel path 48 comprising two opposite arches 54 and 56 concave curves towards the center of the vessel and joined by a predominantly straight sector 58, although slightly curved, on the opposite side of hinge line 25. As track 46 approaches the open end 50 of the fixator, next to hinge line 25, track 46 deviates from the fixator to direct the cursor 100 to a parking spot 60 that allows that the cover 30 can be rotated on the hinge line 25 or removed of the container without interfering with the cursor 100.

As Figures 2a and 2b show, track 46 it can comprise a groove 70 on the upper side of the lid 30 congruent with the concave element 44 of the lockable fastener 40 repeatedly. Slot 70 includes an inner edge 72 closer of the concave element 44 and an outer edge 74 opposite the edge inside 72. The groove 70 on the upper side 32 of the cover 30 forms a heel 76 on the bottom side 34 of the lid 30 that interacts with a complementary groove 80 of the upper side 22 of the edge 20 congruent with the convex element 42 of the fastener 40 closable repeatedly. The groove 80 on the upper side 22 of the edge 20 protrudes from the edge 20 forming a heel 82 on the lower side 24 of the edge 20. The heel 82 of the lower side 24 of the edge 20 includes an inner edge 84 closer to the open end 41 of the element convex 42 and an outer edge 86 opposite the inner edge 84.

The inside edge 84 of the heel 82 on the side lower 24 of edge 20 generally defines a first edge 90 of track 46 of the cursor embodiments described to continuation. In one embodiment of the cursor, the outer edge 81 of the groove 80 of the upper side 22 of the edge 20 forms the second edge 94 of track 46 when said cursor is arranged in the opening mode while the outer edge 74 of the slot 70 from the upper side 32 of the cover 30 forms the second edge 92 of the track when said cursor is arranged in close mode. In another embodiment, the outer edge 74 of the groove 70 on the side upper 32 of cover 30 defines a second edge 92 of the track 46 when the cursor is arranged in both the opening mode and in closing mode.

As Figures 3 and 4 show, cursor 100 is slidably attached to track 46 and can be moved to along the travel path 48. The cursor 100 has a length 102 running parallel to the travel path 48 and a width 104 that runs orthogonally thereto. How show Figures 5a, 5b and 5c, the C-shaped body of the cursor 100 comprises a base 110 having a first surface 112 with a first elongate element 120 and a second elongate element 130 that extend from it in a provision of contiguity. The first elongate element 120 and the second element elongated 130 have proximal ends 122 and 132 that depend on the first surface 112 of base 110, distal ends 124 and 134 that depart from the first surface 112 and interior surfaces opposite 126 and 136. The first elongate element 120 includes a pivot 140 which depends on the inner surface 126 at the end distal 124 projecting to the second elongate element 130. The second elongate element 130 includes a tracking element 160 which depends on the inner surface 136 at the distal end 134 which projects to the first elongate element 120.

The tracking element 160 may be aligned with pivot 140 along the length 102 of the cursor 100 and along the width 104 of the cursor 100. alternatively, the tracking element 160 may be offset of pivot 140 along the length 102 of the cursor and along of the width 104 of the cursor 100. Preferably, as shown by the Figures 5a-5c, the tracking element 160 is offset from pivot 140 along cursor width 104 100 and aligned with pivot 140 along the length 102 of the cursor 100.

In configurations where the lockable fastener repeatedly defines the path of travel 48, the first elongate element 120 and the second elongate element 130 are overlapping on peripheral edges of cover 30 and edge 20 while pivot 140 and tracking element 160 they interact with the locking elements of the fastener 42 and 44. Especially, the pivot 140 can interact with the end 41 of the convex element 42 of the lower side 24 of the edge 20 and the tracking element 160 can interact with the surface without interlocking 47 of the concave element 44 of the upper side 32 of the cover 30.

In the mounted configurations that show the Figures 6a and 6b, the first elongate element 120 and the second elongate element 130 overlap the peripheral edges of the cover 30 and edge 20, when pivot 140 and the element of track 160 interact with slot 70 on the upper side of the cap 30 and the heel of the bottom side 24 of the edge 20. Especially, in the closing mode shown in Figure 6a, the element of tracking 160 is arranged against the outer edge 74 of the slot 70 on the upper side of the lid 30, while the pivot 140 adjoins the inside edge 84 of the heel 82 on the lower side 24 of edge 20. In the opening mode shown in Figure 6b, the tracking element 160 is arranged against the outer edge 81 of the slot 80 on the upper side 22 of the edge 20, while the pivot 140 rests on the inside edge 84 of the heel 82 of the bottom side 24 of edge 20.

The pivot 140 allows the cursor 100 to rotate on the distal end 124 of the first elongate element 120, especially along curvilinear sectors and sectors of transition that have vector components that extend in the X and Y directions. For this reason, pivot 140 comprises a oval outer surface 142, preferably cylindrical, which interacts with track 46. In order that cursor 100 can properly rotate on pivot 140 along sectors curvilinear or transition regions along the trajectory of path 48, pivot 140 is mounted on the concave side of the curvy sectors or transition regions while the tracking element 160 is mounted along the side convex. This allows the base 110 of the cursor 100 to rotate with with respect to distal ends of the elongated members according to the cursor 100 moves along curvilinear sectors of the travel path 48.

The tracking element 160 generally Maintains the union of cursor 100 with track 46 and guides the cursor 100 along the travel path 48. However, the tracking element 160 can also serve as a pivot, especially when the travel path 48 adopts a pattern wavy as a sinusoidal shape that requires both base 110 as the distal ends of the elongated limbs rotate each other depending on the position of the cursor 100 along the travel path 48. The outer surface 162 of the element Tracking 160 is preferably convex in order to minimize friction contact with track 46. Without However, the outer surface 162 is oval, and preferably cylindrical, when it is necessary that the tracking element 160 function as a pivot

Although it is desirable that the cursor 100 can rotate, especially in transition regions along the path of travel 48, it may be necessary to maintain an orientation suitable of the cursor 100 with respect to the lockable fastener 40 repeatedly to ensure that the portions of the cursor 100 that interact with the interlocking elements 42 and 44 described to They are then properly oriented with respect to the fixative. This may allow cursor 100 to function more efficiently. in the opening and closing of the fixative. For example, a suitable cursor orientation 100 may include that the length 102 of the cursor 100 is basically parallel to travel path 48 and that the width 104 be basically orthogonal to it. Bliss orientation can be maintained by a 180 rotation limiter arranged at the cursor 100 that interacts with the lockable fastener 40 repeatedly or track 46.

Although rotation limiter 180 can understand various different configurations to control the cursor rotation 100, the rotation limiter 180 of the cursor that shown in Figures 5a-5c comprises a plug 182 arranged on the inner surface 126, at the end distal 124 of the first elongate element 120 projecting towards the second elongated element 130. As can be seen, the plug 182 is spaced from pivot 140 along the length 102 of the cursor 100 and aligned with pivot 140 along width 104 of cursor 100. Like pivot 140, pin 182 interacts with the path of the path 48 resting on the edge inside 84 of heel 82 on bottom side 24 of edge 20.

The distance between the limiter and the pivot 140 is limited and depends on the travel path 48, especially the radius of curvature of the transition regions of travel path 48. The larger the radius of curvature, the greater the allowable separation distance between the pivot 140 and rotation limiter 180. Also, the smaller be the radius of curvature, the smaller the allowable distance between the same.

Same as pivot 140 and the element of tracking 160, the outer surface of pin 182 has a such that minimizes friction contact with the track 46. The outer surface may be convex in order to Limit interaction with the point of contact.

As previously described, the main 100 cursor function is to favor the union of the elements of interlocking 42 and 44 of fixative fastener 40 repeatedly as move cursor 100 in a first direction 36 that closes the fixative and apply separation forces on the elements of interlocking 42 and 44, as cursor 100 moves in a second address 38 opposite the first address 36 that opens the fixative. The cursor usually includes features that provide These functional characteristics.

In the embodiment shown in the Figures 5a-5c, the cursor 100 includes a wedge 200 arranged at the distal end 124 of the second elongate element 130, adjacent, but opposite, to tracking member 160. Wedge 200 it is arranged away from the first surface 112 of the base 110 to interact with the interlocking elements 42 and 44 of the Fixer 40 repeatedly closable. The wedge 200 comprises a inner surface 202 and an outer surface 204, one end of opening 206 and a closing end 208. The separation 210 between the inner surface 202 of wedge 200 and the first elongate element 120 forms a channel 212 that converges along the length 102 of cursor 100 from a maximum distance at the opening end 206 of wedge 200 to a minimum distance at the end of 208 wedge closure 200.

As you can see, wedge 200 can have truncated cone shape with a concave inner surface 202 and a convex outer surface 204. In order to minimize the friction contact with the fastener components 40 with which interacts, both the inner surface and the outer surface of the wedge can comprise wavy contours that extend from the opening end 206 to the closing end 208. By For example, the contour of the outer surface 204 may be convex with respect to the travel path 48 next to the end of opening 206 and concave with respect to travel path 48 next to the closing end 208, while the contour of the inner surface 202 may be concave next to the end of opening 206 and convex next to the closing end 208.

In the realization of the cursor showing the Figures 5a-5c, wedge 200 performs the function of open and close the fastener 40 repeatedly closable. In the closure configuration shown in Figure 6a, the surface concave interior 202 of wedge 200 partially encloses the bulging surface without interlocking 47 of the concave element formed in the lid 30, while the inner surface of the first elongate element 120 is in contact with the lower side 24 of edge 20 of heel 82, protruding therefrom to form the track 46. According to cursor 100 it moves along the path of path 48 in the first direction 36 of Figure 3, the channel of convergence formed by the concave inner surface 202 of the wedge 200 and inner surface 126 of the first elongate element 120, diagonally joins the interlocking elements 42 and 44 in one sealing arrangement.

Once cursor 100 has traveled the travel path length 48 in the first direction 36 and you have closed the fastener, the cursor 100 can be placed on the opening configuration by reversing the address and interposing wedge 200 between interlocking elements 42 and 44. It is possible to provide a flexible flange 43 that extends from the concave element 44 of fixator 40 on the upper side of the cover 30, at the closed end 52 of the travel path 48, for make wedge 200 initiate the separation of the two elements 40 and 42

In the opening configuration illustrated in the Figure 6b, wedge 200 is arranged between the elements of interlocking 42 and 44 so that the inner concave surface 202 of the wedge 200 partially encloses the surface of interlocking 45 of the convex element while the recess 49 of the concave element encloses the outer surface in the form of truncated cone 204 of wedge 200. As cursor 100 moves in the second direction 38 illustrated in Figure 4, the surface truncated cone-shaped exterior 204 of wedge 200 separates the interlocking elements 42 and 44 and opens the lockable fastener 40 repeatedly.

In the previously described embodiment, the wedge 200 performs both the opening and closing operations forcing the user to fully open or close the Fixer 40 before switching to the opposite operation. Whether provides a cursor that has designated separate components to open and close the fixer, the user can switch from opening to closing mode at any point along the travel path

In an alternative embodiment shown in the Figures 7a and 7b, the cursor 300 comprises a third elongate element 340 that has a proximal end 342 that depends on the first surface 312 of base 310, a distal end 344 and a inner surface 346. The third elongate element 340 is separated from the first elongate element 320 and the second element elongated 330, the second elongate element 330 being interposed between the first elongate element 320 and the third elongate element 340.

The first elongate element 320 and the third elongated element 340 cooperate to perform the closing operation of cursor 300. The inner surface 346 of the third element elongated 340 interacts with the bulky surface without interlocking 47 of the concave element 44, while the inner surface 326 of the first elongate element 320 interacts with the heel 82 which form the track on the lower side 24 of the edge 20. The surface interior 326 of the first elongate element 320 narrows so that the separation 313 between the inner surface 326 of the first elongate element 320 and the inner surface 346 of the third elongated element 340 varies along the length 302 of the cursor from a maximum distance at the opening end 306 to a minimum proximal distance at the closing end 308, forming a convergent channel between them. Distance measurement Minimum proximal is designed to favor the attachment of the interlocking elements 42 and 44 of the fastener 40 closable repeatedly with each other.

In order to minimize the contact of friction between cursor 300 and fastener 40 repeatedly closable, the third elongated element 340 can be modified as shown Figures 8a-8c. The third elongated element 340 it can be shorter than the first elongate element 320 and comprise a finger-like element 350 positioned adjacent to the closing end 308 of cursor 300 projecting so parallel to the width 304 thereof.

In addition, as Figure 9a shows, the element a finger mode 350 comprises an inner surface 352 that interacts with the upper side 32 of the lid 30, especially with the bulging surface without interlocking 47 of the concave element 44. At the same time, the inner surface 326 of the first element elongate 320 interacts with the lower side 24 of the edge 20, especially, the heel 82 that forms the track 46 along the side of the open end 41 of the convex element 42 of the fixator 40 repeatedly closed.

Since the closing operation begins in the closing end 308 of the cursor, the third elongated element 340 shorter can minimize contact with the fixative while the finger-like element 350 cooperates with the first elongated element 320 to favor the engagement of the elements of interlocking 42 and 44 of fixator 40 to each other. With the purpose of provide better compliance with the bulky surface without interlocking 47 of concave element 44, inner surface 352 of the finger-like element 350 can be concavely curved towards the first elongate element 320.

To execute the opening operation in the embodiments illustrated in Figures 7a-7b and 8a-8c, a 360 wedge is interposed between the first elongate element 320 and the third elongate element 340. How to you can appreciate, the 360 wedge can be arranged at the end distal 334 of the second elongate element 330. The wedge 360 is narrows such that the outer surface 362 of the wedge 360, opposite the inner surface 346 of the third element elongated 340, inclines towards the first elongate element 320 from a first end 366 adjacent to the opening end 306 of the cursor 300 to a second end 368 approaching the end of closure 308 of cursor 300. Cross section of wedge 360 descends from the first end 366 to the second end 368.

In its mounted configuration shown in Figure 9b, wedge 360 is interposed between the elements of interlocking 42 and 44 of fixative fastener 40 repeatedly, with the inner surface 364 of wedge 360 partially enclosing the bulging interlocking surface 41 of convex element 42, while the outer surface 362 of the wedge 360 interacts with the recess 49 of the concave element 44. In order to provide greater compliance with both interlocking elements 42 and 44, the inner surface 364 may be concave towards the first elongate element 320 while the outer surface 362 It can be shaped like a truncated cone.

For the 360 wedge that performs the function of opening does not interfere with the features mentioned above that perform the closing operation and vice versa, the second end 368 of the wedge 360 is separated from the closing end 308 of the cursor. Preferably, the second end of the wedge is spaced a predetermined distance of a plane arranged at the end of Closure 308 of cursor 300 defined by the minimum proximal distance between the inner surface 326 of the first elongate element 320 and the inner surface 346 of the third elongate element or surface inside 352 of the finger-like element 350, depending on the realization.
