DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Referring now to the drawings, FIG. 1A shows a front perspective view of a tube and cap assembly 100. Referring to FIG. 1B, tube and cap assembly 100 includes an extruded, unfilled collapsible plastic cylinder 1 attached to a closure cap 13. The cylinder 1 has a side wall 3 and a cap attachment head 5 sealed to one end. The opposite end 7 of the cylinder 1 is open. The attachment head 5 has a flow channel 9 and a first securement portion 11, such as but not limited to threads, a snap ring, grooves, and the like for attachment of the cap 13 to the attachment head 5. The cylinder 1 may be formed from various thermoplastic materials, such as but not limited to, high density polyethylene, low density polyethylene, polypropylene, a polyester such as polyethylene terephthalate, polycarbonates, polyvinyl chloride, and the like.
The cap 13 has a lower portion 15 and an upper portion 17. The lower portion 15 includes a second securement portion 19, such as threads, ridges, grooves, and the like that correspond to and mate with the first securement portion 11 on the attachment head 5 of the cylinder 1. The upper portion 17 of the cap 13 includes a closed end 14 having a top surface. The lower portion 15 and upper portion 17 of the cap 13 are connected by a flexible hinge 21. The lower portion 15 of the cap 13 has a dispensing orifice 25 which cooperates with flow channel 9 of the cylinder 1, and the upper portion 17 of the cap 13 has a plug or projecting fitment 29 which seals the dispensing orifice 25 when the two portions 15, 17 of the closure cap 13 are in closed position. When the cap is in the closed, no-flow, position the boundary between the lower portion 15 and upper portion 17 of the cap 13 is defined by a cap interface 16.
FIG. 2 shows a pressure sensitive label 30 prior to its attachment to the tube and cap assembly 100 of FIG. 1A. Label 30 has a main body portion 35 and a tamper evident portion 36. The interface between the main body portion 35 and the tamper evident portion 36 is defined by a label score 37 that extends along the main body portion 35 and tamper evident portion 36 interface from a first edge of the label 30 to a second edge of the label 30. The label score 37 may be perforated, and is configured to allow the tamper evident portion 36 to be separated from the main body portion 35.
Preferably, the label 30 also includes a tear-away portion 38 to facilitate separation of the tamper evident portion 36 from the main body portion 35. An exemplary embodiment of a tear-away portion 38 is illustrated in FIG. 2 and includes strip defined between two scored lines 39 a, 39 b in the tamper evident portion 36 that extend perpendicular to the label score 37. Alternative embodiments of the tear-away portion 38 may include a single scored line extending perpendicular to the label score 37 and/or a tab attached to the tamper evident portion 36.
Label 30 may include writings, drawings, or any other desired indicia 40. Such indicia 40 may be decorative and/or the indicia 40 may be used to indicate information about the tube and cap assembly 100 such as but not limited to tube contents, origin, manufacturer, indications for use, brand names or logos, instructions for use, and the like. The indicia 40 may extend along the entirety of the label 30. Alternatively, the indicia 40 may be limited to only portions of the label 30, such as but not limited to being limited to only the main body portion 35 or only the tamper evident portion 36.
FIGS. 3A and 3B show the tube configuration during the process of attaching the label 30 to the tube and cap assembly 100. Referring to FIG. 3A, the label 30 is wrapped around the tube and cap assembly 100 such that the label 30 surrounds at least a portion of the cylinder 1 as well as the interface 16 between the cap 13 lower portion 15 and upper portion 17. An adhesive layer 30 b located on the tube and cap assembly 100 contacting side of the label 30 secures the label to the tube and cap assembly 100. In an exemplary embodiment, the label 30 is attached such that the label 30 also extends past the cap closed end 14. Because the label 30 serves as both a label and as a tamper indicator, preferably no other labelling or external tamper indicators are attached to the exterior of the tube and cap assembly 100 besides label 30.
Referring again to FIG. 3A, in an exemplary embodiment, the label 30 is wrapped around and attached to the tube and cap assembly 100 such that the label score 37 circumferentially overlays the interface 16 between the cap 13 lower portion 15 and upper portion 17. In alternative embodiments, the label 30 may be affixed such that the label score 37 circumferentially overlays the tube and cap assembly 100 at a location either along the cylinder 1 or along the cap 13.
Once the label 30 has been arranged about and adhesively attached to the tube and cap assembly 100, heat is applied to the tube and cap assembly 100 to heat-shrink the label 30 to at least the cap 13 portion of the tube and cap assembly 100. As illustrated in FIG. 3B, as a result of the heat treatment the portion of the label 30 extending past the cap closed end 14 is folded over and shrunk to conform to the cap 13 closed end 14 such that the label 30 lies flat along the top surface of the cap 13 closed end 14.
Following fixation of the label 30 to the tube and cap assembly 100 (as shown in FIGS. 3A and 3B), the interior of the cylinder 1 is filled. The cylinder 1 may be filled with any desired contents, such as but not limited to, cosmetics, drugs, ointments, toothpaste, shampoo, food products, chemical compositions, and the like. Referring to FIG. 4, once the cylinder 1 has been filled with the desired contents, the open end 7 of the cylinder 1 is sealed, such as by plastic welding, to form a sealed closed end 7′.
FIGS. 5A-5E illustrate the tamper indication feature of the label-covered tube and cap assembly 100. Illustrated in FIG. 5A is a sealed, unopened label 30 covered tube and cap assembly 100 such as that in FIG. 4. The presence of the tamper evident portion 36 of the label 30 covering the interface 16 between the cap 13 lower portion 15 and upper portion 17 indicates to a user that the tube and cap assembly 100 has not been opened or tampered with. A tube and cap assembly 100 with a partially or completely removed tamper evident portion 36 covering the cap 13 interface 16 (such as seen in any of FIGS. 5B-5E) would indicate to the user that the tube and cap assembly 100 has been opened and/or tampered with.
A user wishing to open the unopened tube and cap assembly 100 of FIG. 5A would begin by removing the tear-away portion 38 as shown in FIG. 5B. Referring to FIG. 5C, with the tear-away portion 38 removed, the user would next detach the tamper evident portion 36 of the label 30 from the main body portion 35 of the label 30 along the label score 37.
Referring to FIG. 5D, the user would continue to detach the tamper evident portion 36 of the label 30 from the main body portion 35 until the entire tamper evident portion 36 was removed. Once the interface 16 between cap 13 lower portion 15 and the upper portion 17 was entirely uncovered (as seen in FIG. 5D), the contents of the tube and cap assembly 100 could be accessed by unhinging the cap 13 upper portion 17 from the lower portion 15 as seen in FIG. 5E.
FIG. 6 is a sectional view of the label 30. Prior to being attached to the tube and cap assembly 100 the label 30 includes three layers: an exterior surface layer 30 a, an adhesive layer 30 b, and a backing layer 30 c. The exterior surface layer 30 a label may include writings, drawings, or any other desired indicia 40. The adhesive layer 30 b includes an adhesive used to secure the label 30 to the tube and cap assembly 100. In an exemplary embodiment, the adhesive layer 30 b extends along both the main body portion 35 and the tamper evident portion 36 of the label 30. In an alternative embodiment, the adhesive layer 30 b extends only along the main body portion 35 of the label 30. In yet another embodiment, the adhesive layer 30 b may include a first adhesive portion extending along the main body portion 35 and a second adhesive portion extending along the tamper evident portion 36, with the adhesive strength of the first adhesive portion being stronger than the adhesive strength of the second adhesive portion.
Prior to attachment to the label 30 to the tube and cap assembly 100, the backing layer 30 c extends at least along those portions of the label 30 along which the adhesive layer 30 b extends. Once the label 30 is ready for attachment to the tube and cap assembly 100, the backing layer 30 c is removed so as to expose the adhesive layer 30 b.
Prior to application of the label 30 to the tube and cap assembly 100, the label 30 is preferably provided on a roll (not shown) consisting of multiple labels 30. During application, the roll of labels 30 is unwound, and individual labels 30 from the roll are wrapped about tube and cap assemblies 100 as the tube and cap assemblies 100 are spun about a mandrel assembly (not shown). While a label 30 is disposed upon the roll, the backing layer 30 c supports the label 30, preventing the adhesive layer 30 b of the label 30 from adhering to other labels 30 on the roll. During the application process, as the individual label 30 is being unwound from the roll of labels 30, the backing layer 30 c of the individual label 30 is simultaneously removed from the label 30 to expose the adhesive layer 30 b of the individual label 30. Once such an individual label 30 has been unrolled from the roll of labels 30 and its backing layer 30 c has been removed, the label 30 is then attached to the tube and cap assembly 100.
An alternative embodiment of a tube and cap assembly 200 to which a tamper-indicating label 230 can be applied is shown in FIG. 7A. As shown in FIG. 7B, similar to the embodiment FIG. 1A, tube and cap assembly 200 includes an extruded, unfilled collapsible plastic cylinder 201 and a closure cap 213. The cylinder 201 has a side wall 203 and a cap attachment head 205 sealed to one end. The opposite end 207 of the cylinder 201 is open. The attachment head 205 has a flow channel 209 and a first securement portion 211, such as but not limited to threads, a snap ring, grooves, and the like for attachment of the cap 213 to the attachment head 205. The cap 213 includes a second securement portion 219, such as threads, ridges, grooves, and the like that correspond to and mate with the first securement portion 211 on the attachment head 205 of the cylinder 201. The cap 213 also includes a closed end 214 having a top surface.
Referring to FIG. 7C, a label 230 having a main body portion 235 and a tamper evident portion 236, similar to the embodiment of FIG. 2, is wrapped around the tube and cap assembly 200 such that the label 230 surrounds at least a portion of the cylinder 201 as well as a portion of the cap 213. In an exemplary embodiment, the label 230 is attached such that the label 230 extends past the cap closed end 214.
With respect to the embodiment of FIGS. 7A and 7B, preferably the label 230 is wrapped around and attached to the tube and cap assembly 200 such that the label score 237 circumferentially overlays the boundary 216 defined by the interface between the cap 213 and the cylinder 201. In alternative embodiments, the label 230 may be affixed such that the label score 237 circumferentially overlays the tube and cap assembly 200 at a location either along the cylinder 201 or along the cap 213.
Preferably, the label 230 also includes a tear-away portion 238 to facilitate separation of the tamper evident portion 236 from the main body portion 235. An exemplary embodiment of a tear-away portion 238 includes a strip defined between two scored lines 239 a, 239 b in the tamper evident portion 236 that extend perpendicular to the label score 237.
FIGS. 8A-8E illustrate the tamper indication feature of the label 230 covered tube and cap assembly 200. Similar to the process described with respect to FIGS. 5A-5E above, a user wishing to open the unopened tube and cap assembly 200 of FIG. 8A would begin by removing the tear-away portion 238 as shown in FIG. 8B. Referring to FIG. 8C, with the tear-away portion 238 removed, the user would next detach the tamper evident portion 236 of the label 230 from the main body 235 of the label 230 along the label score 237. Referring to FIG. 8D, the user would continue to detach the tamper evident portion 236 of the label 230 from the main body portion 235 until the entire tamper evident portion 236 was removed. With the tamper evident portion 236 removed (as seen in FIG. 8D), the contents of the tube and cap assembly 200 are made accessible by disengaging the cap 213 second securement portion 219 from the tube 201 first securement portion 211 as seen in FIG. 8E.
