Title: Security deposit bag

Description:
TECHNICAL INVENTION 
     This invention relates generally to bags and more particularly to bags for secure deposit of articles. 
     BACKGROUND ART 
     Security deposit bags have been devised in the past to securely store and transport valuable articles such as documents, including cash and currency, checks, jewelry, bank deposits, securities, criminal investigation evidence and the like. Such security deposit bags include bags or envelopes constructed from sewn fabric, plastic film, or laminates thereof with a zippered closure. The zippered closure may be secured with a lock or seal. However, such conventional security deposit bags are bulky, expensive, and although enable reuse, also generate a recurring expense in transporting the security deposit bag back to the sender for reuse. 
     Security deposit bags have also been developed that are constructed of disposable material and that are adhesively secured and sealed. U.K. Patent No. GB 2145997A entitled &#34;Tamperproof Bag&#34; and issued to Interpoly Limited, illustrates one such design and includes a bag constructed of polyethylene. An adhesive strip is applied to an inside surface of the bag adjacent the opening and is temporarily covered by a liner. Once the bag has been filled, the liner is removed and the bag sealed by the adhesive strip. The bond of the adhesive strip exceeds the strength of the plastic film used to construct the bag. Any unauthorized attempt to open the bag will result in destruction or visible distortion of the bag material, thus indicating that the bag has been opened. The security deposit bag disclosed in British Pat. No. 2,145,997, although an improvement over other conventional security deposit bags, still exhibits several undesirable characteristics. Once the bag is reopened by rupturing the material of the bag, whether or not by authorized personnel, the contents of the bag are exposed to environmental conditions. It is then difficult if not impossible to reseal the bag. Further, it is inconvenient to limit the materials used to construct the bag to those having a relatively low strength. A visually perceptible distortion in the bag material is not in itself an unambiguous indication that the bag has been opened. The bag may have been merely subjected to external forces that distorted the bag material. 
     DISCLOSURE OF INVENTION 
     The bag includes a first and a second panel joined to form sides and bottom of the bag. An opening is provided for access to the interior of the bag. Adhesive closure means as adhered to the first panel and is adapted to secure the panels together to close the opening of the bag. The adhesive closure means includes tamper indicating means for creating indicia externally of the bag after the adhesive closure means has adhesively secured the panels together and the panels are then separated to open the bag. 
     Thus, a security deposit bag is provided that is inexpensive, disposable and includes an adhesive closure means that provides an unambiguous indication externally of the bag, if the bag has been sealed and reopened.

     DETAILED DESCRIPTION 
     Referring now to FIG. 1, the reference numeral 10 generally indicates a security deposit bag constructed according to the present invention. The security deposit bag in the illustrated embodiment takes the form of a flexible bag, envelope or the like, constructed of a strong, lightweight plastic material such as polyethylene, polypropylene, polyethylene terephthalate, polyvinylchloride, polyvinylidinechloride, vinyl acetate, multilayer films of these and other polymers and copolymers, copolymers of the above materials and others, metal foils, paper and paper-like materials, multilayer constructions of these and other materials. The container of this invention is efficiently and economically constructed so that it may be considered disposable upon receipt at its intended destination, with the contents of the bag removed. The bag 10 may be formed by folding over a rectangular sheet of material and sealing it along its sides. As is also shown in FIG. 2A, the bag thus formed includes bottom 15, right side 16, left side 18 and opening 20 providing access to interior 22 of the bag. Front panel 12 includes front and rear major surfaces 24 and 26, respectively. Rear panel 14 includes front and rear major surfaces 28 and 30, respectively. Although not shown, bag 10 may also be constructed with side and bottom panels, in addition to the front and rear panels illustrated. 
     Since the end edge 32 of front panel 12 and end edge 34 of rear panel 14 of the bag are not aligned, flap 36 is formed by a portion of the rear panel. Flap 36 is provided to enclose opening 20 by folding the front surface 28 of the rear panel over into contact with front surface 24 of front panel 12. 
     Adhesive closure means are provided to adhesively secure the rear panel 14 to the front panel 12 so as to enclose the opening 20. In the illustrated embodiment, the adhesive closure means includes laterally extending adhesive closure strip 38 adhered to the front surface 28 of the rear panel 14 and more specifically to flap 36. 
     The closure strip 38 includes a film backing strip 40 having opposing first and second major surfaces 42 and 44. The following is a non-exclusive list of materials suitable for use as the film backing strip: cellulose acetate, polyethylene, polypropylene, polyethyleneterephthalate, polyvinyl chloride, copolymers, multilayer composites of polymers and/or copolymers. 
     A first layer of adhesive 46 is applied to the first major surface 42 of the film backing strip 40. The first layer of adhesive 46 adheres the film backing strip 40 to the front surface 28 of the rear panel 14. The adhesive may be of any type found suitable, such as a solvent or heat activatable, or a pressure sensitive adhesive. The following is a non-exclusive list of adhesives suitable for use as the first layer of adhesive: styrene-isoprene and/or styrene butadiene elastomers with hydrocarbon and/or terpene tackifiers, synthetic or natural rubbers with tackifiers, acrylic polymers with or without tackifiers, ethylene-acrylic acid copolymers, ethylene-vinyl acetate copolymers, and polyethylene. 
     Second layer of adhesive 48 is applied to the second major surface 44 of the film backing strip. As in the case of the first adhesive layer 46, the second layer of adhesive 48 may be of any type found suitable, such as a solvent or heat activatable adhesive or, the second layer of adhesive 48 may be a pressure sensitive adhesive. The following is a non-exclusive list of adhesives suitable for use in forming the second layer of adhesive: styrene-isoprene and/or styrene butadiene elastomers with hydrocarbon and/or terpene tackifiers, synthetic or natural rubbers with tackifiers, acrylic polymers with or without tackifiers, ethylene-acrylic acid copolymers, ethylene-vinyl acetate copolymers, and polyethylene. 
     In the illustrated embodiment of the invention, the second layer of adhesive 48 is a pressure sensitive adhesive. Therefore, liner 50 is releasably adhered to the second layer of adhesive 48 opposite the film backing strip 40 and is coextensive with the second layer of adhesive. The liner 50 may be constructed of any material suitable for use with the particular adhesive applied to the second major surface of the film backing strip such as a silicone applied paper or plastic film. As is shown in FIGS. 2B and 3, the liner 50 may be removed and the rear panel 14 secured to the front panel 12 of the bag by applying the exposed second layer of adhesive 48 to the front surface 24 of the front panel 12 so that the flap 36 encloses opening 20. 
     For purposes of security, it is desirable to minimize the &#34;dwell time&#34; required for the second layer of adhesive to develop a sufficiently high bond strength to the surface to which it is applied. Preferably, the dwell time is no greater than 0-15 seconds. This precludes or minimizes the risk of undetected opening of the bag prior to the attainment of ultimate bond strengths of the closure strip to the panels. The dwell time may also be reduced by treating the surface to which the closure strip is to be adhered, such as by a corona or chemical treatment. 
     The adhesive closure means includes tamper indicating means for forming indicia providing an unambiguous indication perceptible externally of the bag that the bag has been sealed and reopened. In the illustrated embodiment of the invention, the tamper indicating means includes a layer of low adhesion material 52 applied to the second major surface of the film backing strip prior to the application of the second layer of adhesive 48 thereon. The low adhesion material is applied to the film backing strip in a desired pattern of recognizable indicia, such as spaced undulating stripes shown in FIG. 5 extending longitudinally along the film backing strip. The layer of low adhesion material is substantially less thick than the second layer of adhesive. 
     The low adhesion material is applied to the film backing strip so as to assume an intimate surface to surface contact with the surface of the film backing strip. In the illustrated embodiment, the low adhesion material 52 is applied to the film backing strip 40 in a liquid state and solidifies in intimate surface-to-surface contact with the second major surface thereof. However, the low adhesion material may be applied in a flowable state or in the form of a powder, if it forms an intimate surface to surface contact with the film backing strip. 
     The following is a non-exclusive list of materials suitable for use as the low adhesion material: hydroxypropylcellulose, polyvinyl alcohol, polyvinylpyrrolidone, polyvinylacetate, mixtures and/or copolymers of these materials and others. 
     The materials of the bag, film backing strip, first and second layer of adhesive, and low adhesion material are selected so that the relative strengths of adhesion of the various materials exhibit desired relationships. The first layer of adhesive must adhere more aggressively to the rear panel and the first major surface of the film backing strip than the second layer of adhesive adheres to the front panel and the second major surface of the film backing strip. The second layer of adhesive must adhere more aggressively to the layer of low release material than the layer of low adhesion material adheres to the second major surface of the film backing strip. These relationships may also be facilitated by selecting different adhesives for use in the first and second layers of adhesive, or by treating the areas on the front and rear panels that the closure strip 38 is to be adhered to, such by with a corona treatment or chemical treatment so as to selectively control the relative bonding strengths of the first and second layers of adhesives to the front and rear panels. 
     As shown in FIGS. 2C and 4, after being adhesively secured by the closure strip 38, the rear panel 14 may be detached or delaminated from the front panel 12. As the rear panel 14 is detached from the front panel 12, the pattern of low adhesion material 52 delaminates from the film backing strip, along with a portion of the second layer of adhesive 48 substantially in alignment with the pattern of applied low adhesion material (i.e., preferably at least 90% of the second layer of adhesive coinciding with the pattern of low adhesion material is delaminated from the film backing strip or at least the minimum amounts necessary to form perceptable indicia). The first layer of adhesive 46, the film backing strip 40, and any remaining portion of the second layer of adhesive 48 not coinciding with the pattern of applied low adhesion material 52 will remain adhered to the flap 36 of the bag. 
     The exposed surface of the low adhesion material exhibits a substantially different appearance than do adjacent surfaces. Thus, visibly perceptible indica in the form of the pattern of low adhesion material are created. 
     If the bag is then opened, for whatever reason, it may be quickly and easily adhesively resealed by the closure strip to protect the contents of the bag from the environment, notwithstanding the indicia created thereby. With the rear panel 14 resecured by the closure strip to the front panel as shown in FIG. 5, the non-aligned portions of the second layer of adhesive 48 will resecure the front surface of the front panel. The solidified low adhesion material 52 will not reconform in intimate surface to surface contact with the second major surface 44 of the film backing strip 40. The portions of the second layer of adhesive that don&#39;oincide with the pattern of low adhesion material, however, will resume their original configuration and appearance. A visual discontinuity is created by the space and air trapped between the low adhesion material and the second major surface 44 of the film backing strip as compared to the adjacent portions of the second layer of adhesive in intimate surface to surface contact with the film backing strip. Thus, the indicia formed when the bag 10 was reopened after being secured are visible at the boundaries between the low adhesion material and the non-aligned portions of the second layer of adhesive in the shape of the applied pattern of low adhesion material and the visibility of the indicia is enhanced. It is preferred that the second major surface of the film backing strip be provided with a finish, such as a matte finish, adapted to enhance the contrast of the indicia in the closure strip. 
     Alternatively, a closure strip may be provided as part of this invention and as in any of the embodiments described herein wherein the second layer of adhesive has greater bond strength to the surface of the bag than to the second major surface of the film backing strip. In this embodiment, the entire second layer of adhesive will be delaminated from the film backing strip along with the pattern of low adhesion material. However, the adhesive closure means functions as hereinabove described when the closure strip is reapplied to secure the front and rear panels together. That is, the exposed, non aligned portions of the second layer of adhesive will adhere to the film backing strip while the pattern of low adhesion material will form indicia when delaminated from the film backing strip. 
     In order for the indicia to be perceived externally of the bag when the bag is resealed by the closure strip, it is necessary in the illustrated embodiment of the invention for portions of the closure strip 38 and the bag to be light transmissive. That is, portions of the closure strip and bag must be non-opaque (transparent or translucent, and possibly pigmented) so that the interface of the low adhesion material 52 and second layer of adhesive 48 with the film backing strip 40 is visually perceptable. For instance, in regard to the embodiment shown in FIGS. 1, 2A ,2B, and 2C, the first layer of adhesive 46, and the film backing strip 40, must be light transmissive, as well as the flap 36 of the rear panel -4 in at least that portion overlying the closure strip. As shown in FIG. 5, the indicia in the closure strip are perceptible externally of the bag through the flap 36 of the rear panel 14. Alternatively, the bag of FIG. 1 may be constructed so that the front and rear panels 12 and 14 of the bag adjacent the closure strip, the second layer of adhesive 48 and the low adhesion material 52 are light transmissive, so that the indicia in the closure strip are perceptible though the back side of the bag. 
     FIG. 6 illustrates an alternative embodiment of the invention in which the low adhesion material 52 of the closure strip 38 is applied in a pattern that forms one or more alphanumeric characters. For instance, the pattern may include a warning or message indicating that the bag has been opened. 
     FIG. 7A illustrates an alternative embodiment of the invention with a security deposit bag constructed as described with respect to FIG. 1. Closure strip 38 is adhered to the front surface 28 of the rear panel 14. The closure strip 38 includes a pattern of low adhesion material 52 applied directly to the front surface 28 of the rear panel 14, as opposed to a surface of the film backing layer as shown in FIGS. 1-2C. The low adhesion material 52 is placed in intimate surface to surface contact with the front surface 28 of the rear panel as previously described. In FIG. 7B, the liner 50 has been removed and the second layer of adhesive 48 applied to the front surface 24 of the front panel 12 to secure the closure strip 38 and enclose the opening 20 of the bag. 
     In FIG. 7C, the bag 10 has been opened and the rear panel 14 detached from the front panel 12. However, in this case, the pattern of low adhesion material 52 has delaminated from the front surface 28 of the rear panel along with a portion of the first layer of adhesive 46 substantially in alignment with the pattern of low adhesion material to form the indicia. The remainder of the first layer of adhesive 46 remains on the rear panel. 
     In this embodiment the relationships of the strengths of the adhesion of the various materials must be varied from that previously discussed in regard to the embodiment in FIGS. 1, 2A, 2B and 2C. Specifically, the second layer of adhesive must adhere more aggressively to the front panel and the second major surface of the film backing strip than the first layer of adhesive adheres to the first major surface of the film backing strip or the rear panel. 
     If desired, the front and rear panels 12 and 14 may be resecured to each other by the closure strip 38 through the exposed portion of the first layer of adhesive 46 which is not in alignment with the low adhesion material. The indicia are visible at the boundary of the low adhesion material 52 and the front surface of the rear panel. The indicia are perceptible externally of the bag by providing at least a portion of the front and/or rear panel and closure strip light transmissive. In all other respects this embodiment is as described with respect to the embodiment in FIG. 1. 
     In FIG. 8, another alternative embodiment is shown that includes a closure strip 38 and a bag 10 as described in regard to FIG. 1. However, the closure strip includes a pattern of low adhesion material 52 applied to both the first and second major surface 42 and 44 of the film backing strip 40 in a manner previously described so as to be in intimate surface to surface contact with each of the opposing major surfaces of the film backing strip. In this embodiment, the first and second adhesive layers 46 and 48 may have substantially equal bond strengths to the front surface 28 of the rear panel 14 and the front surface 24 of the front panel 12. The closure strip will thus form indicia equally well on either side of the film backing layer responsive to which side of the closure strip is delaminated from the front and rear panels. In this embodiment, it is necessary that the first adhesive layer, second adhesive layer, and portions of the front and rear panels and both patterns of low adhesion material be light transmissive so that the indicia formed by the closure strip are externally perceptible. 
     FIG. 9A illustrates yet another alternative embodiment of the invention in which the closure strip 38&#39; may be formed directly on the front surface of the rear panel, or alternatively separately formed and subsequently applied to a bag, such as in the form of adhesive transfer tape. In FIG. 9A, the second layer of adhesive 48 and the film backing strip 40 have been omitted. Low adhesion material 52 has been applied directly in a desired pattern on the front surface 28 of the rear panel 14. A layer of adhesive 46 is applied over the low adhesion material generally in a transverse strip along the front side of the bag. A releasable liner 50 is applied to the layer of adhesive 46 prior to use. With the liner removed, the rear and front panels are secured together bag by the adhesive layer 46 of the closure strip 38&#39; (as in FIG. 9B). 
     In this embodiment the layer of adhesive must adhere more aggressively to the rear panel than to the front panel, when adhered thereto. The layer of adhesive must adhere more aggressively to the front panel when adhered thereto, than to the layer of low adhesion material. The layer of adhesive must adhere more aggressively to the layer of low adhesion material than the layer of low adhesion material adheres to the rear panel. 
     If detached (as in FIG. 9C) indicia are created by the pattern of low adhesion material, as hereinabove described, and when reapplied, the indicia remain at the interface of the low adhesion material and the front surface of the rear panel. The indicia are perceptible externally of the bag through light transmissive portions of the bag and closure strip as previously described. 
     FIG. 10 illustrates an alternate embodiment of the invention in which the front and rear panels 12 and 14 of the bag may be opaque. A closure strip 38&#34; is provided to secure the rear panel 14 to the front panel 12 of the bag and includes film backing strip 40 that extends beyond edge 34 of the rear panel. The second layer of adhesive is preferably a pressure sensitive adhesive and is covered by a releasable liner (not shown) prior to use. The first layer of adhesive is, however, preferably a non-tacky adhesive, such as a solvent or heat activatable adhesive. The film backing strip 40 extends beyond the edge of the rear panel so that a portion of the first layer of adhesive 46 is exposed. Indicia may be formed by applying the second layer of adhesive 48 to the front panel to secure the front and rear panels together then delaminating the closure strip from the front panel. The indicia are perceptible externally of the bag, such as through a light transmissive portion of the film backing strip 40 and first layer of adhesive 46 extending beyond the edge of the rear panel. 
     FIG. 11 illustrates an alternative embodiment of the bag 10 and closure strip 38&#34; of FIG. 10 in which a portion of the first layer of adhesive 46 adjacent the rear panel and a portion of the second layer of adhesive 48 extending beyond edge 34 of the rear panel 14 have been omitted. In all other respects this embodiment of the invention is as hereinabove described. Specifically, in the embodiments of the invention shown in FIGS. 10 and 11, the relationship of the various strengths of adhesion are as described with respect to the embodiment shown in FIGS. 1, 2A, 2B, 2C and as discussed hereinabove. 
     FIG. 12 illustrates yet another embodiment of the security deposit bag of this invention, in which the closure strip 38&#39;&#34; is adhered to the rear surface 30 of the rear panel 14. Film backing strip 40 has a first layer of adhesive 46 applied to the first major surface 42. Preferably, the first layer of adhesive is a pressure sensitive adhesive, with a portion of the film backing strip and the first layer of adhesive extending beyond the rear panel. The portion of the first layer of adhesive 46 extending beyond the rear panel contains the tamper indicating means in the form of the pattern of low adhesion material 52. A removable liner 50 may be applied to the exposed portion of the first layer of adhesive prior to use. The exposed portion of the first layer of adhesive 46 may be used to secure the front and rear panels together as previously described and to create indicia perceptible external to the bag if the bag is opened after being secured. A single sided pressure sensitive adhesive closure strip is advantageous in that it is less expensive than a double sided adhesive closure strip. 
     The layer of adhesive must adhere more aggressively to the layer of low adhesion material that the layer of low adhesion material adheres to the film backing strip. 
     FIGS. 13 and 14 illustrate yet another alternate embodiment of the security deposit bag of this invention in which closure 38&#39;&#34;, similar to that shown in FIG. 12, is adhered to rear surface 30 of the rear panel 14. A pattern of low adhesion material 52 is formed in the first layer of adhesive 46. Opening 54 is formed in the flap 36 portion of the rear panel 14. The closure strip 38&#39;&#34; is arranged so that the pattern of low adhesion material coincides with the opening 54. Although not shown, a removable liner may be applied to the exposed portion of the first layer of adhesive 46 on the front surface 28 of the rear panel prior to use. Indicia are formed when the pattern of low adhesion material 52 is delaminated from the film backing strip 40 along with a portion of the layer of adhesive 46 substantially in alignment with the pattern of low adhesion material. The closure strip may be used to resecure the front and rear panels together, as previously described. In addition, the relative strengths of adhesion are as described with respect to the embodiments shown in FIG. 12. 
     The following examples of closure strips constructed according to this invention are but a few of the many possible embodiments. Security Deposit Bags comprising closure strips, as illustrated in referenced figures, are further examples of embodiments of this invention.

     Yet another alternative embodiment that is not illustrated, is one in which the film backing strip 40 is formed from a thermoplastic adhesive such as polyethylene. In such a case, the film backing strip may be bonded directly to as bag panel and the first layer of adhesive omitted. The closure strip may be initially adhered by heat bonding the thermoplastic film backing strip to either bag panel for securement against the bag panel of a bag, or the closure strip may be initially secured by the first layer of adhesive 46 to a bag panel for securement to the other bag panel. The light transmissive properties of the various portions of the closure strip and the bag would be altered accordingly to enable external visual perception of the indicia. 
     A closure strip (not shown) may also be applied to opposing inside surfaces of the front and rear panels adjacent the opening of the bag. In such a configuration, at least a portion of the front or rear panels must be light transmissive for external perception of indicia. The flap may be omitted from the rear panel in such a case. It is only essential that the closure strip be utilized to secure the front panel to the rear panel to enclose the opening. 
     Alternatively, the closure strip may be applied to the front surface 28 of the rear panel 14 in the interior of the bag and the flap 36 omitted. Also, the closure strip 38 may be adhered to the rear surface 26 of the front panel 12 for securement to the front surface 28 of the rear panel 14; or the closure strip may be applied to the front surface 24 of the front panel 12 for securement to the front surface 28 of the flap portion 36 of the rear panel 14, in the illustrated embodiments, without altering the functioning of the invention as herein described. 
     The adhesive closure means, forming part of this invention incorporating tamper indicating means, may be utilized on any container, such as bottles, boxes or the like, to adhesively secure container parts together and provide an unambiguous indication that the container was sealed and reopened. However, in all other respects, the adhesive closure means is as herein described. 
     The present invention has now been described with reference to multiple embodiments thereof. It will be apparent to those skilled in the art that many changes can be made in the embodiments described without departing from the scope of the present invention. Thus the scope of the present invention should not be limited to the structures described in this application, but only by structures described by the language of the claims and the equivalents of those structures.
