DETAILED DESCRIPTION OF THE INVENTION

[0029] An embodiment of this invention, illustrating its features, will now be described in detail. The words comprising, having, containing, and including, and other forms thereof, are intended to be equivalent in meaning and be open-ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items.

[0030] The terms first, second, and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and the terms a and an herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.

[0031] The present invention relates to a method (100) for marking identity codes on a cartridge authentication scanning of unique identity codes on the cartridge. The method involves printing unique identity codes on the cartridge at a defined location with the help of an eye mark so that the unique identity codes are clearly scanned by external scanning devices to avoid rejection during quality check and/or verification of data integrity for serialization. Also, the method prevents the botheration of the non-scan ability of the Code due to Position Shift or rotation around its axis. Furthermore, the method provides clear colour contrast between the unique identity codes and the cartridge to provide proper visibility of the unique identity codes.

[0032] The disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms.

[0033] Referring to FIG. 1, a method (100) for marking unique identity codes (10) on a cartridge (20) is illustrated in accordance with the present invention. The cartridge (20) is a rigid or flexible container for holding any material either in semisolid form or solid form. The cartridges (20) are used in rock excavation, chemical, construction, food processing, manufacturing industries etc. In the present embodiment, the cartridge (20) is of a flexible material, and the cartridge (20) is used to store materials like water gels or emulsion or slurry or food materials or any other and the like (30).

[0034] The method (100) starts at step 110.

[0035] At step 120, a rectangular polymeric film (40) with edges (40a and 40b) is selected for marking unique identity codes (10) thereon, as shown in FIG. 2. In the present embodiment, the polymeric film (40) is a High-Density Polyethylene (HDPE) or a Low-Density Polyethylene (LDPE) material or any other material, including paper. The polymeric film (40) has an eye mark (90) printed on a predefined location of the polymeric film (40). The location of the eye mark (90) is dependent on the requirement of a user. The eye mask is a black-coloured mark to enable external scanning devices (such as an optical sensor, cameras) to identify a start position of a portion on a packaging to be scanned.

[0036] The scanning device (not shown in the figure) get triggered when the eye mark is detected. The polymeric film (40) has a white background thereon for providing a colour contrast between the polymeric film (40) and the identity codes (10) thereon. The geometrical dimension of the polymeric film (40) is configured according to the geometrical dimensions of the cartridge (20). In the present embodiment, the polymeric film (40) is in the rolled form initially.

[0037] At step 130, two or more unique identity codes (10) are marked on a predefined location (20a) over the polymeric film (40) along a width direction (40c) of the polymeric film (40), as shown in FIG. 2. The location (20a) of the identity codes (10) is at a predefined distance from the eye mark (90). The distance of the identity codes (10) from the eye mark (90) is based on the type of external scanning device (such as an optical sensor, camera). In one of the embodiment, the location (20a) of the identity codes (10) is closer to the central portion of the polymeric film (40), as shown in FIG. 2. The identity codes (10) are marked over the polymeric film (40) in two or more rows in an asymmetric manner, as shown in FIG. 2. In the present embodiment, each of the identity codes (10) are identical (i.e. contains equal/same information). The unique identity codes (10) are unique machine-readable codes for storing information data of the cartridge (20) such as a batch number and/or manufacturing date and/or expiry date and/or a lot number and/or a manufacturing code and/or a unique identification number or any such information linked with the cartridge in an encrypted form or non-encrypted form.

[0038] In the present embodiment, the unique identity codes (10) are two-dimensional codes or quick response codes or barcodes or human-readable data or alphanumeric codes or alphabetic codes. The unique identity codes (10) are marked on the polymeric film (40) by any printing machine. The unique identity codes (10) are printed on the polymeric film (40) by a suitable print option such as a solvent-based or water-based, or UV curable ink or thermal transfer overprint or other suitable print option for preventing smudging of the unique identity codes (10). The polymeric film (40) has a white background thereon to provide clear visibility between the unique identity codes and the polymeric film.

[0039] At step 140, the polymeric film (40) is rolled along a length direction (40d) of the polymeric film (40) for forming a hollow cylindrical body (50), as shown in FIG. 3. During rolling of the polymeric film (40), the edges (40a and 40b) of the polymeric film (40) are attached to form a closing edge (40e), as shown in FIG. 3. After rolling, the polymeric film (40) is formed into a hollow cylindrical body (50) with two open ends (50a and 50b), as shown in FIG. 3. In the present embodiment, the open ends (40a and 40b) are attached by folded crimps or rolled crimps or wire ties or glue or an adhesive tape such as a packing tape or a Teflon tape, or a staple machine etc.

[0040] At step 150, the material (30) is filled inside the hollow cylindrical body (50) through one of the open ends (50a or 50b) by sealing the other end (50a or 50b) of the hollow cylindrical body (50) as shown in FIG. 2. The material (30) is filled inside the hollow cylindrical body (50) by a manual/automatic/semiautomatic filling machine. In the present embodiment, the material (30) is a chemical or a water gel or an emulsion or a food item etc. One of the ends (50a or 50b) is sealed by folded crimps or rolled crimps or wire ties or a staple machine or glue or an adhesive tape.

[0041] At step 160, the other open end (50a or 50b) of the filled cylindrical body (50) is sealed to form a cartridge (20), as shown in FIG. 4. In the present embodiment, the other open end (50a and 50b) is sealed with folded crimps or rolled crimps or wire ties or any other such process. In one of the embodiment, the rolling of the polymeric film (40), filling the material (30) in the hollow cylindrical body (50) and sealing ends of the cylindrical body (50) are performed by a cartridge packaging machine. The unique identity codes (10) are marked on the polymeric film (40) in such a way that the unique identity codes (40) are visible along a complete circumferential area (40g) of the cylindrical cartridge (10). Due to the visibility of the multiple identity codes (10) over the entire circumferential area (40g), the scanning device can scan any of the identity codes (10) clearly, eliminating the problem encountered due to a single identity code (10). The marking of the identity codes (10) over the cartridge (20) prevents errors in scanning due to the shifting of the identity codes (10) during the rotation of the cartridge (10) around its axis.

[0042] The method (100) ends at step 170.

[0043] After forming the cylindrical cartridge (20), the cartridge (20) moves for further processes if necessary. The cartridge is carried for further processing on a conveyor (110), as shown in FIG. 5. In these processes, there are external impurities may get deposited on the surface of the cartridges. To remove the external impurities such as dust, oil, dirt, and other external particles, a hot air blower (70) is configured over the conveyor (110), as shown in FIG. 5. The hot air blower (70) removes external impurities by blowing the air over the surface of the cartridge (20). Further, the moisture or water particles deposited on the surface of the cartridge (20) are removed by a 360-degree circular air knife (80) or air curtain before scanning the unique identity codes (10), as shown in FIG. 6.

[0044] The air knife (80) is a circular ring-like structure configured over the conveyor (10) in such a way that when the cartridge (20) passes through the air knife (80), the air knife (80) encloses the entire circumferential area (50) of the cartridge (20) as shown in FIG. 6. The air knife (80) blows a high velocity compressed air in a radial direction over the circumference of the cartridge (20) to remove moisture content accumulated over the cartridge (20). After cleaning the cartridge (20) with the air knife (80), the scanning device (such as a camera) arranged along the conveyor (110) scan the identity codes (10).

[0045] Thus, the present invention provides a method (100) for printing unique identity codes (10) on a cartridge (20), which provides a simple and unique way of printing unique identity codes over the surface of the cartridge (20). Moreover, the cartridges (20) made from the method (100) enables the scanning devices to clearly scan the unique identity codes (10) and prevent rejection during the manufacturing process. Further, the method (100) involves a simple and cost-effective process. Also, the method (100) removes the external impurities such as dust, oil, dirt, and other external particles from the surface of the cartridge (20). Also, the method (100) provides clear visibility and colour contrast between the unique identity codes (10) and the surface of the cartridge (20).
