The PCT international application claims priority based on US Patent Application No. 60 / 658,229 filed May 26, 2005. The applicants for designations in all countries other than the United States are Reynolds Consumer Products, Inc., the United States. Timothy Jay, Mercquire Greg Wrew and Hendricks Chad Ay.

  The present invention relates to a sealing tool for a flexible bag. In particular, the present invention relates to a sealing device having a tampering-inhibiting portion that indicates that there has been a tampering action by displaying it on a window when there is unauthorized access to the contents of the bag.

Patent Documents 1 to 11 describe a safety bag body that is used for transporting valuable items such as currency, which has a sealing means that suppresses unauthorized opening of the bag body and unauthorized access to its contents.
In Patent Documents 8, 9, and 10, in order to suppress unauthorized opening and display that there may have been unauthorized access, the unauthorized opening suppression / display sealing tool of the safety bag body of the previous example uses an adhesive substance. is doing.
In Patent Documents 2, 3, 6, and 7, the notch and the stamped portion are used simultaneously or selectively.
US Pat. No. 5,908,243 US Pat. No. 5,631,068 US Pat. No. 5,620,256 US Pat. No. 5,407,277 US Pat. No. 5,352,041 US Pat. No. 5,350,238 US Pat. No. 5,318,364 US Pat. No. 5,108,194 US Pat. No. 4,491,196 US Pat. No. 4,838,708 U.S. Pat. No. 4,653,113

  Unfortunately, the chemical / mechanical system is useless in environments that are exposed to extreme temperatures, if not typical. In addition, precedent mechanical systems, such as selectively notched interlayers, are powerless to skillful mechanical manipulation and / or visual evidence of tampering. Will not leave immediately. When opened, these systems do not immediately confirm that the safety bag has been tampered with or attempted to open. Accordingly, the safety bag sealing means of the prior example does not have the required level of tampering prevention. What is required is a valuables storage bag sealing system that can immediately confirm tampering. Furthermore, there is a need for an unauthorized opening display sealing tool that operates with an unrestricted reliability when an unauthorized access is made to the contents of the bag.

In one embodiment, the present invention provides a closure having at least one groove member suitable for engaging an occlusal portion and at least one fitting member disposed opposite thereto.
The fitting member is
(I) Stem portion that couples the occlusal portion of the fitting member to the edge portion of the fitting member (ii) The stem portion is coupled to the stem portion by a breakable connecting portion, and the sealing member is sealed by engaging with the groove member 1 Alternatively, the breakable connecting portion having a plurality of locking projections is a force that is less than the force required to release the fitting member and the groove member engaged by cutting the locking projection from the fitting member. Torn.

  In a certain embodiment, the groove member of the sealing device according to the present invention has a visual recognition window capable of visually recognizing the occlusal protrusion of the fitting member, and therefore, for the packaged body sealed by the sealing device. After being accessed, it can be visually confirmed that the locking projection of the fitting member is cut. That is, a visual indication of access activity may be provided. In an embodiment, the engaging protrusion and the groove member are provided with different colors that can be distinguished from each other, and the coloring can visually recognize the engagement state between the engaging protrusion and the groove member. Furthermore, it contributes to highlighting that the locking projection of the fitting member of the sealing tool is in a cut state.

  In some embodiments, the fitting member is (1) an airfoil illustrated in FIG. 1, for example, (2) an arrow shape illustrated in FIG. 2, for example (3) C illustrated in FIG. Or (4) a locking projection having a cross-sectional shape selected from, for example, a double arrow shape illustrated in FIG. 4, and the groove member meshes with these locking projections So that it has a cross-sectional shape selected.

  In one embodiment, the breakable connecting portion between the locking projections coupled to the stem of the fitting member is generated by a groove-shaped notch that penetrates the material including the fitting member. In some embodiments, the fit-in members are separated. In one isolated embodiment, the fit-in member has a series of equally spaced members and a plurality of gaps separating each member. In some embodiments, the members are regularly arranged. In one isolated embodiment, the regularly arranged members are button-shaped in plan view.

In an embodiment, the sealing device according to the present invention includes:
(A) at least one groove member for engaging the fitting member, having a visual recognition window capable of visually recognizing the fitting member being bitten;
(B) (i) One or a plurality of latches that are coupled to the stem portion by the stalk portion coupled to the fitting member and (ii) the breakable coupling portion and seal the sealing device by engaging with the groove member And at least one fitting member that has a protrusion and is arranged to engage with the groove member.
The breakable connecting portion is broken by a force that is less than the force required to release the engaged fitting member and the groove member by cutting the locking projection from the fitting member.
The groove member is attached to one bent portion of the self-standing two-fold member, and the fitting member is attached to the other bent portion of the two-fold member, and the two-fold member is folded in two along the fold line. By doing so, the groove member and the fitting member are engaged with each other.

  In one embodiment, the occlusal member is coupled to one side wall of the opening of the bag, and is arranged to take in the side walls on both sides of the opening of the bag between the engaged groove member and the fitting member. The In some embodiments, the fitting members on the folded member are separated. In one embodiment, the opposite side walls of the bag body to which the bi-fold member is joined have at least one pair of opposed holes, and a part of the separated fitting member is engaged with the groove member. The hole is once penetrated before. In some embodiments, the fit-in member has a series of regularly spaced apart parts, each separated part being attached with a bi-folded closure before engaging the opposite groove member. It penetrates through a pair of holes perforated on opposite side walls of the opening of the bag.

  In some embodiments, the closure of the present invention includes an opening in a flexible package. In some embodiments, the flexible package is a bag. In one embodiment, the opening of the package includes a sealing tool, and the sealing tool further includes a groove member and a separate fitting member that defines a series of locking projections. Each locking projection cooperates with at least a portion of the groove member to seal the seal. In a certain embodiment, a package body contains the bag body which has an opening part with which the sealing tool was attached | subjected. At least a portion of the separated fitting member passes through the wall of the bag through at least one pair of opposed holes.

  The present invention takes measures against the above problems. The present invention provides a sealing tool having an occlusal portion that realizes a sealed state. Furthermore, when a force that is less than the force required to release the occlusal portion is applied to the closure, at least one of the occlusal parts breaks, producing a visible indication that it has been opened.

  In certain embodiments, the present invention requires a means such as a slider that allows a closure to provide a high sealing force in order to perform the initial sealing of the bag. In some embodiments, after being used to seal, the slider is removed from the sealed bag. The trace of the slider (track) prevents the slider once removed from being remounted. In some embodiments, the slider completely covers the seal and continues to cover the seal as it is installed after the initial seal. In this embodiment, since the slider cannot be removed without causing the display unit indicating that there is an action to remove the slider to function, the tampering-preventing force selective or additional to the sealing tool. Will give.

The sealing device according to the present invention is believed to be most useful when attached to the opening of a safety bag and used to seal access to the interior of the bag.
The opening is, for example, an opening of a plastic safety bag described in any of Patent Documents 1 to 11 and US Pat. No. 4,785,960, the contents of which are referred to here.

The closure of the present invention has a number of components, which are generally extended from the edge or a pair of opposing surfaces that may be formed from the underlying material. Including an occlusal portion. Any one of these is also described here for convenience, or its occlusion is the base material that seals the closure.
The sealing tool may use a slider as an aid for engaging the sealing portion. In general, the slider is guided and supported by a rail portion or other member attached to the edge portion or wall portion of the material according to the use situation. In the sealing tool of the present invention, at least one tamper-evident display means is woven into the occlusal portion and / or slider (when used) of the sealing tool.
Below, the occlusal part of the sealing tool, the slider, and finally the method of creating the sealing tool will be described in order.

(Occlusal part)
As described above, the sealing device of the present invention has two occlusal portions that cooperatively close an opening portion of the package body to which the sealing device is attached, such as an opening portion of a safety bag. FIG. 1A illustrates a cross-sectional view of an occlusal portion of one embodiment of a sealing tool. The occlusal portion of the sealing tool includes a groove member 10 and a fitting member 100. The fitting member 100 has locking projections 101 and 102 that form an occlusal portion of the fitting member 100, is engaged with the groove member 10, and is engaged with the groove member 10.
The groove member 10 in FIG. 1A has a viewing window 14, and side walls 11 and 12 are attached to the viewing window 14. A second viewing window 13 is attached to the side walls 11 and 12. A gap 15 is provided in the second viewing window 13. One side of the side wall 12 and the second viewing window 13 supports the sealing portion 16. The sealing part 16 is used in order to affix a sealing tool on the side wall of a package. The fitting member 100 has a stem portion 108, and locking projections 101 and 102 are attached to the stem portion 108 via breakable portions 103 and 104, respectively. The stem portion 108 is attached to the edge portion 110 of the fitting member that supports the sealing portion 105. The sealing part 105 is used in order to attach a sealing tool to the other side wall facing the side wall of the package body to which the sealing part 16 is attached.

As shown in FIG. 1B, the locking projections 101 and 102 are engaged in the gap 15 until the surfaces 106 and 107 of the locking projections 101 and 102 mesh with the surfaces 1 and 2 of the viewing window 13. Thus, the fitting member 100 is engaged with the groove member 10. When engaged, the occlusal portion of the groove member 10 and the fitting member 100 can be confirmed through the viewing window 14 (between BB) and the second viewing window 13 (between A and A).
In some embodiments, the locking protrusions 101, 102 are colored. And since the surfaces 1 and 2 of the visual recognition window 13 are colored in a different color, when the occlusion between the fitting member 100 and the groove member 10 is completed, a pair of colors along the longitudinal direction of the sealing tool are colored. The locking projections 101 and 102 appear through the viewing window 14 as parallel lines. Details of such occlusal closures are described in US Pat. Nos. 5,356,222, 5,252,281, and 5,248,201, respectively.

  Further, as shown in FIG. 1B, stress is applied to the breakable portions 103 and 104 during occlusion. When a force is applied to the sealing member in order to remove the fitting member 100 from the groove member 10, one or both of the locking projections 101 and 102 are separated from the stem 104 along the breakable portions 103 and 104. . As a result, the state of the fitting member 100 visually recognized through the viewing window 14 changes from a pair of parallel lines to a single thick thick line. This is because the force applied for the engagement with the groove member 10 at the time of occlusion, that is, the force pressing the locking protrusion separated from the inner surface of the visual recognition window 14 is released. The stem portion 108 of the fitting member 100 does not continue to bite along the longitudinal direction of the gap 15. As a result, the state of the stem portion viewed through the second viewing window 13 does not appear as a single uniform color line. Therefore, once the groove member 10 and the fitting member 100 are engaged with each other, if the both members are to be removed, the locking projection portion of the fitting member 100 is surely cut, and the above-mentioned indication indicating that the sealing tool has been opened appears. It will be.

  If the gap 15 does not expand sufficiently because the size of the various parts of the groove member 10 and the fitting member 100 requires a large force to separate them, the breakable part is cut to remove the sealing member. It would be desirable to allow the occlusal fitting member 100 to be removed without activating the visible tamper-evident display portion or making the damage to the groove member 10 serious and visually detectable. It is desirable that the breakable portion be broken only by applying an insufficient force to remove the occlusal portion of the sealing tool.

1 (b) and 1 (c), generally, the rigidity and size of the groove member 10 and the fitting member 100 are easily sealed depending on the finger pressure pressing the groove member 10 and the fitting member 100 of the sealing tool. The ingredients are selected so that they are not sealed. When a pressure higher than a level that can be easily supplied by finger pressure is required to bite the sealing tool, it is preferable to use the slider 17 that bites the groove member 10 and the fitting member 100.
In general, when the slider 17 is used, the thickness of the edge 110 of the fitting member that hooks the extension claw portion 111 of the slider is determined so that the slider 17 is fitted to the edge of the fitting member while a sealing force is applied. It is preferable that the thickness be sufficient to prevent it from coming into close contact with 110 and receiving a twisting force, or preventing a gap from opening. Similarly, the size of the side wall 12 is preferably such that the surface 3 catches the extended claw portion 4 of the slider 17, and the width of the extended claw portion 4 of the slider 17 is in close contact with the side wall 12. It is preferable that the width is sufficient to prevent the twisting force from being excessively applied or the gap from being opened and removed.

In some embodiments, the closure is attached to the safety bag 18 and includes an end stop 19. When not in use, the slider 17 is in a position adjacent to the end stop 19, and this position corresponds to a state in which the sealing tool is not engaged. As the slider 17 moves in the direction of arrow C in FIG. 1C, the groove member 10 and the fitting member 100 are engaged.
In some embodiments, there is no opposite end stop 19 and when the user has sealed the seal, the slider 17 is removed from the seal and discarded. Generally, the slider 17 has no means for separating the occlusion of the sealing tool. This is different from a conventional slider that alternately engages and releases the sealing tool.

As described above, FIG. 1 shows a fitting member 100 having an airfoil-shaped locking projection and a groove member 10 that can be engaged with it. FIG. 2 (a) shows another embodiment of the sealing device of the present invention, that is, a cross-sectional view of the arrow-shaped locking projection 201 on the fitting member 200 and the groove member 20 that can be engaged with it. Has been.
As shown in FIG. 2A, the groove member 20 has a visual recognition window 24 to which side walls 21 and 22 are attached. Walls 23 and 26 extend from the open side of the side walls 21 and 22, which limit the width of the gap 25. The wall 26 has a portion extending beyond the side wall 22, and a sealing portion 216 is attached to this portion.
Further, referring to FIG. 2A, the fitting member 200 has an arrow-shaped locking projection 201 attached to the stem 209 via the breakable portion 203. The stem 209 is attached to the edge 210 of the fitting member. A sealing portion 205 is attached to the edge portion 210 of the fitting member. As shown in FIG. 2A, the breakable portion 203 is formed by making one notch on the side near the sealing portion 205 of the stem portion 209 adjacent to the locking projection 201. Can be formed.
As shown in FIG. 2 (c), alternatively, the breakable portion 203 is provided with a pair of parallel cutouts 223 and 233 on both sides of the stem 209 on the side close to and far from the sealing portion 205. Can also be formed.
It can be seen that the arrow-shaped locking protrusion 201 shown in FIG. 2A is less flexible than the airfoil-shaped locking protrusions 101 and 102 shown in the fitting member 100 of FIG. Accordingly, as shown in FIG. 2 (a), the locking projection 201 can be engaged with the gap 25 of the groove member 20 leaving sufficient space, and the surface 206 of the locking projection 201, The walls 23, 26 that limit the width of the gap 25 in the groove member 20 have a cross section with a thickness that provides flexibility such that 207 can engage the surfaces 241, 242 of the groove member 20. In some embodiments, the walls 241, 242 are mounted at an angle so that when engaged with the locking projection 201, they are tensioned therebetween.
As shown in FIG. 2B, this tension gives a force that the locking projection 201 acts in the direction of arrow C inside the groove member 20. As shown in FIG. 2 (b), the force not only ensures a strong sealing along the opening 250 of the bag body 253, but also supplies a force to hit the locking projection 201 against the inner surface of the visual window 24. . Then, the breakable portion 203 is torn.
As described above with respect to the sealing device shown in FIG. 1, the interaction portion between the groove member and the fitting member is made of a material that is contrastably colored so that the occlusion state and the cutting state of the sealing device can be visually recognized, and the sealing device is opened. Then, it can be visually displayed that there has been an illegal act.

As shown in FIG. 2 (b), some embodiments use a slider 217 to facilitate occlusion of the closure. In the case of the sealing device shown in FIGS. 1 (a) to 1 (c), the edge portions and groove members of the fitting members that support the sealing portions 205 and 216 are sufficient to hook the extended claw portions 251 and 252 of the slider. It is preferable that the thickness is selected to have a sufficient thickness. Further, it is preferable that the extended claw portion of the slider has a sufficient width to prevent the slider from being twisted or detached during use.
As described above for the embodiment of FIG. 1, in some embodiments, it is contemplated to use a slider that is removed and discarded after the initial seal is sealed.

3 (a) and 3 (b) show a cross-sectional view of a fitting member having a C-shaped locking projection and a groove member engaged with the fitting member. FIG. 3B shows the fitting member 300 and the groove member 30 which are separated. The fitting member 300 has a C-shaped locking projection 301 attached to the stem 309 via a breakable part formed by the notches 302 and 303. The stem 309 is attached to the edge 310 of the fitting member, and the sealing part 305 is attached to the edge 310 of the fitting member. The C-shaped locking projection 301 has claw portions 306 and 307. The groove member 30 has a visual recognition window 34, side walls 31, 32, and L-shaped walls 33, 36 extending from the side walls. The L-shaped wall 36 extends beyond the side wall 32, and a sealing portion 316 is attached to the extended portion. The L-shaped walls 33 and 36 limit the width of the gap 35 and the interval between the claw portions 341 and 342 of the groove member 30. The groove member 30 may optionally have breakable portions 362 and 363, and may additionally have one or more breakable portions 302 and 303 on the fitting member 300. The selectively breakable portion may be inside the intersection of the side wall 31 and the L-shaped wall 33 (shown as a breakable portion 362) and / or inside the intersection of the side wall 32 and the L-shaped wall 36 (breakable portion). (Noted as 363).
In this way, in response to the act of trying to remove the fitting member and the groove member without cutting the breakable portion of the fitting member, the groove member was subjected to a force such as opening and the like, and was made by a notch. It will be cut along the breakable portion. Therefore, such a notch contributes to leaving easily visible evidence showing that an attempt to eliminate the function of visually confirming the tampering of the sealing tool has been made. In general, the notch can be formed along any part of the fitting member or the groove member, but it is desirable to form a part that is cut when the part receives a force. From this description, it can be seen that many variations on the location of the notch that provide the breakable portion leaving evidence of tampering can be considered, and that variation can be within the scope of the present invention.

In order to engage the fitting member and the groove member, the claw portion 306 of the fitting member enters between the side wall 31 and the claw portion 341 of the groove member, and the claw portion 307 of the fitting member becomes the side wall 32 and the claw portion of the groove member. The locking protrusion 301 of the fitting member 300 is engaged with the groove member 30 through the gap 35 until it enters the space 342.
As shown in FIG. 3A, when the fitting member and the groove member are engaged with each other in this way, the opening portion of the bag body attached to the sealing member of the fitting member and the groove member exerts a force on the groove member and the fitting member. Sealed securely without hanging. However, if an attempt is made to extract the fitting member from the engaging groove member, the tensile force concentrates on the breakable portion of the groove member and the claw portion of the fitting member. Even if the breakable portion is located between the stem portion and the claw portion of the fitting member, the breakable portion is located between the side wall and the L-shaped wall of the groove member, or both the breakable portions are simultaneously This tensile stress is generated even at the position.

The breakable portion is formed by notching in the major axis direction (302A, 302B) of the stem at the intersection of the locking projection and the stem or in the direction intersecting with the major axis of the stem (see FIG. FIG. 3 (a) also shows that it can be formed by notching 3 (b) 302, 303). As described above with respect to other embodiments, the size and material of the sealing tool may be selected such that it is not practical to engage the fitting member and the groove member using finger pressure. Thus, the slider 317 can be used to bite the parts of the seal.
For convenience, the sealing device may be arranged such that the slider claw 351 moves along the side wall 32 of the groove member 30 and the slider claw 352 moves along the bottom of the edge 310 of the fitting member. . As described above, the occlusion portion of the fitting member and the groove member 30 can be colored, so that the occlusal state can be visually recognized by looking at the occlusion portion through the visual recognition window 34. Further, any unauthorized operation that cuts the sealed portion can be viewed through the viewing window 34.

FIG. 4 shows a cross section of a groove member 46 having an arrow-shaped central locking projection 43 that meshes with a fitting member having a double arrow-shaped locking projection 44. As shown in the figure, the groove member 46 has claw portions 401, 402, 403, 404, which engage with the claw portions 411, 412, 413, 414 on the locking projections of the fitting member. In the illustrated embodiment, the groove member 46 has viewing windows 41 and 42 through which the locking projections of the fitting member can be viewed. Similarly, the fitting member also has a visual recognition window 422, through which it can be visually recognized that the central locking projection 43 is engaged with the fitting member.
The breakable part formed by the notches 431, 432, 433, 434, 435 is shown in FIG. These give the part cut | disconnected by the nail | claw part of a groove member and a fitting member. FIG. 4 (b) shows that these breakable portions can also be formed by a pair of cutouts. The notches are formed on both sides of the stem portion (432A, 432B, 434A, 434B) connecting the double arrow-shaped locking projection of the fitting member to the edge of the fitting member, and the central locking projection is used as a groove member. It is also formed on the stem portion of the central locking projection to be connected (433A, 433C). As in the other examples described above, in some embodiments, a slider is used to occlude the groove member and the fitting member.

Fig.5 (a) is sectional drawing of the sealing tool which has the latching protrusion part 500 isolate | separated from the groove member 50 of the state which is not meshed | engaged. FIG. 5B is a cross-sectional view of the locking protrusion 500 separated from the engaged groove member 50. As shown in FIG. 5 (a), the side walls 551 and 552 of the package 550 to which the sealing device is attached have at least one pair of opposed hole portions 553, and the locking projection portion 500 and the stem portion. 501 penetrates these hole portions 553 immediately before meshing with the groove member 50.
The stem portion 501 has a breakable portion 502. When a force is applied to release the engaged locking projection 500 from the groove member 50, the breakable portion is cut. The groove member 50 in FIG. 5B has a visual recognition window 51. The viewing window is transparent (between A and A), through which the engaged fitting member and groove member can be seen.
As shown in FIG. 5 (c), in one embodiment, the separate fit-in members are a series of regularly arranged buttons (561A-561F) that are defined as groove members. When occluded, they appear in the viewing window 51 as a series of regularly arranged shapes. As shown in the other embodiments described above, when the engagement member separated from the groove member is engaged, the locking projection 500 is separated from the stem 501 and no longer visible from the viewing window 51. Since buttons that are not regularly arranged are visually recognized, it is possible to visually recognize that there has been an illegal act of opening the sealing tool by looking at the viewing window.

  FIG.5 (d) is the figure which looked at the button-shaped latching protrusion part of the fitting member separated by the front view shown in FIG.5 (c) from the top.

As further shown in FIG. 5 (a), the isolated seal and any other seals of the present invention are attached to separate flanges (a typical method for occlusal seals), or , And can be provided as a two-part sealing device having a groove member and a fitting member coupled to a double-folded flange.
The method of making a double-folded flange is to mount or injection-mold the groove member and the fitting member on separate flanges and join them together at one edge part of each, or to form a groove on one base material. When the member and the fitting member are mounted or injection molded, and the base material is folded along the fold line, the groove is formed or cut at a position where the fitting member and the groove member fit the hole. There is a method of making a fold line with a notch.
The fold line or the connecting line of such a bi-folder may be parallel to the major axis of the sealing tool or may be perpendicular. The basic material having a fold line parallel to the major axis of the sealing tool is shown in FIGS. 5 (a) and 5 (b). Accordingly, the two-fold sealer 570 includes a piece 571 on which the groove member 50 is attached or injection-molded, a piece 572 on which the stem 501 and the locking projection 500 are attached or injection-molded, and 2 When the two pieces 571 and 572 are folded in two along the fold line, the groove member 50 and the fold line are arranged at positions where the locking projections 500 face each other so that they can be engaged with each other.
When the double-folding sealing tool is used, it is necessary to attach only one side of the base material (a sealing part can be attached to the one side) to the opening of the package. As shown in FIG. 5A, with such an arrangement, the flange 52 is attached to the side wall 551 of the bag body 550. The attachment position is such that the gap 53 of the groove member 50 coincides with the hole portion 553 drilled in the side wall 551 of the bag body 550. In order to seal the package, the piece 572 is bent and the locking projection 500 is inserted into the gap 53 of the groove member through the hole 553 of the bag. When a necessary pressure is applied to the straight portion, the locking projection 500 penetrates the hole 553 of the bag body and engages with the groove member 50.

  Generally, when a bi-fold piece is used, the bi-fold piece is made of a plastic that is more rigid than the material of the bag. It is preferable to use the material, size and / or design of the piece such that the two-folded piece has a self-supporting characteristic. In some embodiments, the bi-fold is a structure and made from a rigid material.

  The separate fitting member can be made specifically by injection molding or by milling or cutting unwanted portions of a continuous fitting member by conventional extrusion generation. Either way, starting with a small blank milled against the fitting member, which can be used in correspondence with a generally rectangular hole, for example the mushroom shape shown in FIGS. 5 (a) to 5 (d) All forms of fit-in members can be provided, ranging from button-shaped members that can be used with circular holes such as fit-in members. In addition, it can be seen that the cooperative relationship between the discontinuous fitting member and the hole of the bag body can be used with the same effect.

Like the other embodiments described above, in some embodiments, a slider is required to provide the force required to bite the closure. In FIG. 5B, a slider 580 using a groove member having a key-shaped cross section as a guide can be used.
In FIG. 5C, the sealing tool has an end stop 590 that is adjacent to the slider 580 when the sealing tool is not sealed. End stop 590 maintains the seal on an unsealed container. After the container is filled, the slider is operated in the direction of arrow C to occlude the occlusal portion of the sealing tool. After the sealing tool is sealed, the slider is further moved in the direction C, removed from the sealed package, and discarded.

  The material and size of the occlusal portion of the closure is at least about 2.3 kilograms of force to separate the occlusal portion of the closure, more preferably at least about 3.6 kilograms of force, more preferably at least about A force of 4.5 kilograms is selected, more preferably at least about 6.8 kilograms of force.

  Preferably, the breakable portion is formed by making strategic cuts in the occlusal portion of the fitting member and / or groove member. It will be appreciated that other methods can be used such as selective continuous drilling, application of relatively weak material to the breakable portion. Preferably, the breakable portion is selected such that it breaks when a force less than that required to separate the occlusal portion of the closure is applied to the sealed closure.

  Preferably, it resists the force of prying the occlusal portion of the closure and releases the occlusal portion without impact that can be detected extensively and immediately, such as receiving the force of opening or actuating the tampering indication means of the closure The material properties of the sealing material that is sufficiently rigid to be selected are selected. The materials and methods will be described in detail later. The material of the sealing device of the present invention is selected so that, by softening, the mechanical operation cannot be opened without activating the tamper-evident display function of the sealing device.

(Unauthorized tamper indication slider)
In some embodiments, the seal may include a conventional occlusal seal (not using a breakable portion) with a slider that leaves a tamper indication. An example of this is the slider 600 shown in FIG.
The slider 600 is selected to have a length that exceeds the length (along A-A) of the closure that operates the slider. The slider for storing the sealing tool when the sealing tool is in the sealed position has a closed end 601. Further, the sealing tool on which the slider 600 operates has an end stop 603. When the sealing tool is in an unsealed position (when the slider is on the left side as shown in FIG. 6A), the end stop serves to maintain the slider 600 on the sealing tool.
The slider 600 has a shaving off means 602. After the sealing tool is sealed by being operated in the direction E, if the slider is operated in the direction F in order to open the sealing tool, the shaving off means 602 shaves off the fitting member of the sealing tool. The slider further includes means 606 for bringing the member 609 shaved off from the fitting member 604 by the shaving-off means 602 to the side, and a dust collecting chamber 608 for storing the member brought to the side. The presence of a shaved member in the dust collection chamber 608 can be confirmed by viewing the dust collection chamber through a visual recognition window 607 provided on the slider upper surface 610. In some embodiments, the fitting member of the seal is colored and the dust collection chamber is colored in contrast to the fitting member, so that the shaved member indicates that unauthorized access has been made. The presence of can be immediately visible.

  Although there are many means that can be immediately recognized by shaving off the member of the sealing tool, the shaving means shown in FIG. 6C is similar to a razor injection-molded inside the slider adjacent to the wall surface of the dust collecting chamber 608. With sharp protrusions. A more flexible L-shaped member 606 fixed only to the upper surface 610 of the slider 600 peels off the shaved member from the razor and drops it into the dust collecting chamber 608. It can be seen that other arrangements are considered based on this description. The use of only the above-described tamper-evident display slider has a sufficient effect, but there may be an application example in which the slider is used in cooperation with the above-described one or more tamper-evident display sealing tools.

(Method for creating the sealing tool of the present invention)
Preferably, the sealing device of the present invention is made of a plastic material that is durablely attached to a safety bag body to which the sealing device is attached. Preferably, the sealing tool is made of a material that can withstand opening, softening by heat, and hardening by freezing. An example of a suitable material is polypropylene. A polypropylene closure is described in US patent application Ser. No. 10 / 726,731 filed Dec. 2, 2003 (the '731 application).
