DETAILED DESCRIPTION
[0071] A method for labelling objects with labels in accordance with the present disclosure is shown in the sequence of FIGS. 1-10. The method of FIGS. 1-10 is conveniently practical when labelling objects with small labels (in a range of millimeters or a few centimeters at most), in particular when applying such small labels on small surfaces or small objects. A non-exhaustive list of fields and objects to which the method of the present disclosure may be beneficial is provided below.
[0072] Referring to FIG. 1, a plurality of adhesive dots 10 (a.k.a., instrument adhesive) are illustrated, as being on a backing strip 12. The adhesive dots 10 may be on any appropriate backing format (a.k.a., liner), such as a sheet, a single-dot piece, etc. In an embodiment, the backing strip 12 is part of a dispenser device.
[0073] Referring to FIGS. 2 and 3, a transfer instrument 14 is shown. The transfer instrument 14 may have any appropriate body shape so as to be manually handled by a user. The transfer instrument 14 is shown as being an elongated rod of circular cross-section, with one or more flat contact end surface 14A, and a bend in the rod adjacent to the contact end surface 14A. The transfer instrument 14 is thus shaped as a stylus to be handled as a pen, but other geometries are contemplated (not just elongated), such as with a wider body, such as a paddle, with any appropriate cross-sections, including various polygonal sections—square, rectangle, triangle, hexagonal, octagonal, etc. or other symmetric or asymmetric or atypical sections. In an embodiment, the instrument 14 may have a combination of shapes such as a cylindrical shape body and a square or polygon-shape tip or any other combination of shapes and configurations. The transfer instrument 14 can be in any color and might be blank or printed with any graphic, image, logo, barcode, serial number or data. The transfer instrument 14 may comprise a punch, a hole, embossed area, drilled hole, a carve, groove, stamp (a design) or a relief or an attachment such as a metal ring to attach a hand-strip. The transfer instrument 14 may incorporate a battery operated light or a digital device such as a clock/timer, or a wireless communication tag or device such as RFID or NFC tag. The contact end surface 14A is shown as being a flat or quasi-flat surface. However, other types of surfaces are possible, though flat is preferred for the adhesion of the adhesive dot 10 to it, in the manner shown in FIG. 3. Indeed, as shown in FIG. 2, the transfer instrument 14 is used to pick up an adhesive dot 10. The transfer instrument 14 is hovered over one of the dots 10, and pressed upon it for the dot 10 to adhere to the contact end surface 14A. The adhesion between the dot 10 and the contact end surface 14A is greater than between the dot 10 and the backing 12, as the backing 12 is designed with a view to allowing a release of the dot 10. The diameter of the contact end surface 14A (e.g., 0.05″-0.5″, 0.2″-1″) may be equal or greater than that of the adhesive dot 10, so as not to have the dot 10 exceed the perimeter of the contact end surface 14A. In another embodiment, the adhesive is in a liquid or gel form in any appropriate recipient, and the end of the transfer instrument 14, including the end surface 14A is dipped into the adhesive to cover at least the end surface 14A. In another embodiment, the instrument 14 is a glue stick, with a glue cylinder being displaceable out of the receptacle of the glue stick. In another embodiment, the displaceable cylinder comprises a chamber with a liquid or gel-like or wax-like glue that can exit from the tip of the instrument 14. The tip may comprise a mesh-like surface or a surface with holes through which the glue can pass to be exposed at the end surface 14A of the tip of the instrument 14. The glue can be displaced through the cylinder through a lip-stick or glue-stick like mechanism manually actuated or through an electronic module pressing the glue out of the instrument 14.
[0074] The concepts of adhesion and adhesion force are used herein to describe the bond between the adhesives and the surfaces they contact. Other expressions for adhesion may include “tack”, “tackiness”, “stickiness”, “bond surface energy”, “bonding forces”, “adherence”, “peel adhesion value”, etc. For simplicity, the expression “adhesion” is mostly used throughout. The adhesion parameters may for instance be measured by loop tack, and referred to as “adhesion force” according to ASTM (American Society for Testing and Materials).
[0075] Referring to FIGS. 4 to 6, the transfer instrument 14 with adhesive 10 at the end surface 14A is then used to collect a transfer label 16. In FIG. 4, a plurality of transfer labels 16 are illustrated, as being on a backing sheet 18. The transfer labels 16 may be on any appropriate backing format (a.k.a., liner), such as a sheet, a single-label piece, etc. The transfer labels 16 have a single face with adhesive, namely the one applied to the backing 18. The transfer labels 16 typically have a dimension similar or slightly smaller to that of the end surface 14A.
[0076] In similar fashion to the picking up of the dot 10, as shown in FIG. 2, the transfer instrument 14 with adhesive 10 is used to pick up the transfer label 16 in FIG. 5. The transfer instrument 14 is hovered over one of the labels 16, and pressed upon it for the adhesive-less surface of the transfer label 16 to adhere to the contact end surface 14A by way of the adhesive 10. The adhesion between the dot 10 and the transfer label 16 is greater than between the transfer label 16 and the backing 18 as the backing 18 is designed with a view to allowing an easy release of the label 16. After this operation, the transfer label 16 is at the end of the transfer instrument, as in FIG. 6, with its tacky surface exposed and leading the end of the transfer instrument 14.
[0077] The same operation is repeated, as in FIGS. 7 and 8, but with a target label 20, i.e., the one that will be identifying an object. In FIG. 7, a plurality of target labels 20 are illustrated, as being on a backing strip 22. The target labels 20 may have information inscribed or printed thereon, for identification of an object 24. The target labels 20 may be on any appropriate backing format (a.k.a., liner), such as a sheet, a single-label piece, a roll, etc. The target labels 20 have a single face with adhesive, namely the one applied to the backing 22, and with information written on the main face, i.e., the exposed one without the adhesive. The target labels 20 may include electronic components, such as RFID or NFC chips. In an embodiment, the target label 20 is an RFID or NFC tag comprising adhesive. The target labels 20 typically have a dimension equal to or smaller than that of the transfer label 16.
[0078] In similar fashion to the picking up of the dot 10 and of the transfer label 16, as shown in FIG. 2 and FIG. 5, respectively, the transfer instrument 14 with adhesive 10 is used to pick up the target label 20. The transfer instrument 14 is hovered over one of the labels 20, and pressed upon it for the adhesive-less surface of the target label 20 to adhere to the contact end surface 14A by way of the tacky surface of the transfer label 16. The adhesion between the target label 20 and the transfer label 16 is greater than between the target label 20 and the backing 22 as the backing 22 is designed with a view to allowing an easy release of the label 20 therefrom. After this operation, the target label 20 is at the end of the transfer instrument 14, as in FIG. 8, with its tacky surface exposed and leading the end of the transfer instrument 14.
[0079] The target label 20 may then be applied to the object 24, herein shown as a vial just by way of example. The exposed tacky surface of the target label 20 is positioned against the target surface of the object 24, and pressure is applied for the target label 20 to adhere to the target surface of the object 24. As shown in FIG. 10, the transfer label 16 remains on the transfer instrument 14, such that the sequence of FIGS. 7, 8 and 9 may be repeated to place another target label 20 on an object 24.
[0080] In an embodiment, the method of manual application may be regarded as having three steps: 1) peeling and lifting of the small target label 20 from the support liner 22; 2) Placing it on a small or confined area or on an object 24; and 3) releasing it from the transfer instrument 14.
[0081] The method is based on the fact that the adhesion force of the target label 20 to the target surface of the object 24 is stronger compared to the adhesion force of the transfer label 16 to the surface of the target label 20. The difference in the adhesion force causes a detachment of the target label 20 from the adhesive of the transfer label 16, and results in its transfer to the object 24.
[0082] Also, at the same time, the adhesion force of the adhesive 10 to the non-adhesive surface (facestock) of the transfer label 16 is stronger than the adhesion force of the adhesive of the transfer label 16 to the target label 20 which allows the transfer label 16 to remain attached to the adhesive 10 during or after the transfer of the target label 20 to the object 24. After a number of transfers, the transfer label 16 or the adhesive dot 10 or both can be changed, for the same instrument 14.
[0083] As mentioned above, in order to achieve the relative adhesion properties described above, the adhesion parameters can be measured by loop tack, and peel adhesion according to ASTM (American Society for Testing and Materials), to ensure the above-described bonding forces are applied for the method to be adequately performed. The values will depend on the surface of the object 24 on which the target labels 20 are being applied and the facestock material of the labels 16 and 20. The importance is the difference between adhesion forces of the adhesive of the target label 20 being applied to the object 24 and the adhesive of the transfer label 16 applied to the face of the target label 20, and this may be coined as relative adhesion values as well. Therefore, the adhesion value of the target label 20 should be stronger than the adhesion value of the transfer label 16 to the respective surfaces.
[0084] According to other embodiments, the instrument 14 is a disposable rod with a preattached adhesive label on the end surface 14A, or even on opposed ends thereof. The instrument 14 may be a disposable rod when the transfer adhesive is coated directly on the end surface 14A and other end surface (no need for transfer label 16).
[0085] The method may be used in the following fields, activities, objects: Labelling of small vials, biomedical containers, small objects and devices, hard to label locations such as surfaces that located on the bottom of a well-like container, or have an indentation, or inside crevices, electronic boards and components, electronic devices, clean room applications, electrical equipment and wiring, automotive industries, avionics, instrumentation, gages, labelling procedure requiring a magnifying glass or a microscope, jewelry, optical and in any other type of industrial, research or field where an identification with small labels are required. The rod or the instrument can be customized to have a different shape or configuration to meet the requirements of the labelling application, as exemplified herein after with reference to FIG. 16. The rod can be made of a wide variety of any types of materials including but not limited to materials that have a flexibility to twist and turn the rode under any angle or extend it to a desired length. In an embodiment, the instrument 14 consists of a material including one or more of the following: a plastic, glass, metal or wood. The glue, the target label and/or transfer label can have any shape or configuration, such as circle, rectangle, square, triangle, polygon and any other symmetric or asymmetric or atypical shape. The target label 20 and the transfer label 16 can be printed or blank. The target label 20 and/or transfer label 16 can be of any shape or can be in any format, e.g. roll, sheet, fanfold, stripe, booklet, etc.
[0086] Referring to FIGS. 11 to 15, an alternative embodiment is shown, in which the transfer label 16 has both of its faces coated with an adhesive, in such a way that the adhesive dot 10 is not required to stick the target label 20 on the object 24. FIG. 11 shows one possible construction of the transfer label 16 on the backing 18, identified in the FIG. 11 as support liners. As both sides of the label face of the transfer label 16 have an adhesive, the transfer label 16 (including its label face and adhesive layers) may be sandwiched between a pair of backing sheets 18, i.e., the support liners in FIG. 11. In that manner, the transfer labels 16 are protected from inadvertent contact with their environment before they are adhered to the transfer instrument 14. To assist in the removal of one of the support liners from the transfer label 16, or in the detachment of a transfer label 16 from the other support liner by use of the transfer instrument 14, an adhesive release layer may be provided on the support liners 18 as shown in FIG. 11. The adhesive release layer may be an integral coating on the support liner 18 (e.g., a wax or a silicone, among other examples). Alternatively, the support liner 18 may have non-stick properties that may not require the presence of any additional adhesive release layer. As shown in FIG. 14, the series of layers of FIG. 11 may define a matrix surrounding the transfer label 16 by appropriate liner cuts. It is contemplated to have a series of layers without such matrix as well.
[0087] As the transfer labels 16 may be used one at a time in the method described above by manipulation of the transfer instrument 14, the support liner(s) may be provided with liner cuts or perforations as shown in FIG. 12, to expose one transfer label 16 at a time, to define elongated strips of transfer labels 16, or to allow squares of one transfer label 16 and support liner(s)/backing sheet 18 to be separated from a remainder of the sheets of FIG. 12. The combination of slits (a.k.a., cuts) and perforations allows stripping away the support liner 18 through the cut lines, and separating desired sections through the perforations while maintaining the structural integrity of the sheet. The cuts and the perforations of different layers including the support liners and the transfer label material itself can be in any direction or orientation. Furthermore, the cuts and perforations may have some angles, curved shaped configurations and twists or combinations thereof to facilitate the manipulations. These are options among others. Moreover, while FIGS. 11 and 12 show a round transfer label 16, other shapes are considered as well. FIG. 13 shows a few shapes among others, for the transfer label 16. Some of the shapes include a tab 16A. The transfer label 16 with a tab 16A may be sized in such a way that the tab 16A projects beyond the contact end surface 14A of the transfer instrument 14 in the manner shown in FIG. 15. The tab 16A may consequently be used for a user to manually pull the transfer label 16 off of the instrument 14, to change it when one or more target labels 20 have been applied to an object 24 with the transfer label 16 and the transfer label 16 has lost some tackiness. The tab 16A may also increase the contact surface of the transfer label 16 on the end surface 14A of the instrument 14, resulting in a better adherence in view of repeated uses of a same transfer label 16 in numerous target label applications.
[0088] The adhesion between the contact end surface 14A of the transfer instrument 14 and the transfer label 16 may be greater than between the transfer label 16 and the backing 18 (support liner) as the backing 18 is designed with a view to allowing an easy release of the label 16. It is therefore contemplated to have adhesives on the transfer label 16 with different adherence properties, such as tackiness, loop-tack or peel adhesion, to ensure that the transfer label 16 sticks on the contact end surface 14A of the transfer instrument 14 while being picked up, and for the target label 20 to transfer onto the object 24 from the transfer label 16, with the transfer label 16 remaining on the instrument 14. According to an embodiment, the adhesives on opposite sides of the transfer label 16 may be the same although the loop-tack and peel-adhesion values may be different between the target label 20 and object surface compared to the transfer label 16 and the facestock of the target label 20. However, as it is desired that the transfer label 16 remain on the instrument 14 while the target label 20 attaches and detaches from it, the contact end surface 14A may have given adhesion properties to cause a greater adherence with the transfer label 16 than that of the transfer label 16 on the support liner (backing 18), or than that of the transfer label 16 with the target label 20. The contact end surface 14A may be chosen for its adhesion properties, whether or not it is used with a transfer label 16 having distinct adhesives.
[0089] The transfer label 16 can be provided as a separate unit, as a refill to be used with the instrument 14, for instance in the form of sheets as in FIG. 12. The transfer label 16 as well as any components described in the present disclosure can be provided in a sterile condition, individually or as combined with other components such as the instrument 14, caps 30 for the instrument 14, target labels 20, and/or the objects that will be labeled. All or some parts of a kit may be sterilized, or they can be provided as non-sterile that can be sterilized by the user.
[0090] As another embodiment, with reference to FIG. 16, the instrument 14 may have be configured to have both ends 14A capable of accepting glue dots 10 or transfer labels 16. For example, the instrument 14 may have an S-shape (FIG. 16) or C-shape capable of transferring target labels 20. It is contemplated to use the same adhesive dot 10 (FIG. 3) or transfer label 16 in multiple cycles of target label transfer, over separate time periods. Accordingly, as shown in FIG. 16, the end surfaces 14A of the instrument 14 may be protected with caps 30. The caps 30 may include a non-stick liner in their internal cavity, such as a silicone liner. It is contemplated to provide the instrument 14 with an adhesive dot 10 and/or transfer label(s) 16 pre-applied to the end surface(s) 14A, and in such an arrangement a cap(s) 30 may be useful in protecting the transfer label(s) 16 or more specifically protecting the adhesive surface of the transfer label 16.
[0091] The instrument 14 may have more than one tip on each end or on either end, it might have exchangeable tips for different shapes and/or dimensions, or it might have a rotational configuration allowing revolving of available tips. According to an embodiment, the instrument 14, with or without glue, can be sterile or can be sterilised such as via autoclaving, gamma irradiation, ethylene oxide or other method. The transfer label 16 can be in a sterile condition or can be sterilised such as via autoclaving, gamma irradiation, ethylene oxide or other method. In an embodiment, a kit is provided in a sterile condition, or that can be sterilised, the kit including the instrument 14, with or without a glue, one or more transfer labels 16 with or without target labels 20. The kit may include an object for the target label, all of which may be in a sterile condition or sterilisable.
