DETAILED DESCRIPTION
[0106] In
[0107] The cavities 14, 16, 18 are configured to receive or to accommodate at least an elongated component 60 of a drug delivery device 1 as illustrated in
[0108] As shown in
[0109] As illustrated in
[0110] The depressions 20, 22, 24 are located between the cavities 14, 18 as seen along the first direction (X). Along the second direction (Y) there are provided non-interrupted longitudinal rows of cavities 14, 16 and depressions 20, 22. Along the first direction (X) there's provided a first column 41 of an alternating arrangement of cavities 14, 18 and depressions 20, 22. Next to the first column 41 and offset from the first column 41 along the second direction (Y) there is provided a second column 42 of an alternating arrangement of cavities 16 and depressions 22 and so on.
[0111] As illustrated, the depressions 20, 22, 24 are of circular shape. As shown in
[0112] As further illustrated in
[0113] With typical examples, the body 11 is a one-piece injection molded plastic body. It is of excellent dimensional stability and can be used multiple times for transporting and/or storing components of a drug delivery device.
[0114] The longitudinal end 52 of the protuberances 54 protruding downwardly from the bottom side 15 of the bottom area 12 or the body 11 comprises an aperture 53. Hence, the longitudinal end 52 of the protuberances 54 is open and non-sealed. Even though the cavities 14, 16, 18 seem to provide a pocket hole they have an open distal end. Such an open end or aperture 53 is of particular benefit for cleaning of the workpiece carrier 10, e.g. with a cleaning agent, such as water and/or a detergent.
[0115] The aperture 53 at the longitudinal end 52 provides a residue-free draining of a liquid cleaning agent. Moreover, the open longitudinal end 52 of the protuberances 54 and/or of the respective cavities 14, 16, 18 provides and enables an improved drying of the workpiece carrier 10 in the process of workpiece carrier cleaning with a liquid cleaning agent.
[0116] Typically, the longitudinal end of the protuberances 54 are void of an end face. Hence, the sidewall 51 of the protuberances 54 is void of an end face. In this way, a residue-free draining of a liquid cleaning agent can be easily provided. This enables use of the workpiece carrier 10 in an environment classified as predefined clean room class.
[0117] The open longitudinal end of the protuberances are particularly provided by way of injection molding. For providing the open longitudinal end of the protuberances there is no elaborate post-processing necessary. The workpiece carrier 10 can be provided by single shot or by a multi-component injection molding process.
[0118] Typically, the depressions 20, 24 are located midway between adjacently located cavities 14, 18. In particular, the depression 20 is located midway between the cavities 14, 18. Interstices 55 on the bottom side 15 of the bottom area 12 located between adjacently located protuberances 54 of a second workpiece 10′ carrier may become aligned with the cavities 14, 16, 18 of the first workpiece carrier 10 and may therefore provide room for an upright orientation and accommodation of elongated or longitudinally shaped components 60 of a drug delivery device 1.
[0119] As illustrated in
[0120] The workpiece carrier 10 comprises a rectangular structure. The planar-shaped bottom area 12 is of rectangular shape and adjoins an upwardly protruding side wall 10 protruding from the upper side 13 of the planar-shaped bottom area 12. The sidewall 100 encloses the entirety of the bottom area 12. The sidewall 100 forms a rectangular frame 101 that contributes to the stability and stiffness of the workpiece carrier 10. The sidewall 100 comprises an inside surface 130 and an outside surface 120. The sidewall 100 further comprises a first sidewall portion 140 and an oppositely located second sidewall portion 141. There is further provided a third sidewall portion 142 and a fourth sidewall portion 143 located opposite to the third sidewall portion 142.
[0121] The first and the second oppositely located sidewall portions 140, 141 are substantially of the same dimensions. The third and the fourth side wall portions 142, 143 also match in size and geometry. There are further provided numerous corner sections 135 by way of which the first sidewall portion 140 adjoins the third sidewall portion 142, the third sidewall portion 142 adjoins the second sidewall portion 141 and the second sidewall portion 141 adjoins the fourth sidewall portion 143, respectively.
[0122] The respective sidewall portions 140, 141, 142, 143 form a closed and non-interrupted sidewall and hence a circumferential frame of the workpiece carrier 10. The sidewall 100 comprises an inside surface 130 and an oppositely located outside surface 120.
[0123] On the inside surface 120, the sidewall 110 comprises a lower sidewall section 102 and an upper sidewall section 104. The lower sidewall section 102 adjoins the upper side 13 of the bottom area 12 and the upper sidewall section 104 adjoins the lower sidewall section 102. Between the lower sidewall section 102 and the upper side wall section 104 there is provided a stepped section 106. The stepped section 106 provides a well-defined abutment for a nested arrangement of workpiece carriers 10, 10′ stacked on top of each other.
[0124] As indicated in
[0125] Of course, in the nested configuration, which is indicated in
[0126] As further illustrated in
[0127] As illustrated in the partial cross-section of
[0128] Typically, there are provided numerous struts 131, 132, 133 along the first sidewall portion 140 and along the second sidewall portion 141 in this way, oppositely located corner sections 17 of the second workpiece carrier 10′ can engage with the beveled edges provided by the struts 131, 132, 133.
[0129] As further illustrated in
[0130] As further illustrated in
[0131] The outside surface 120 of the sidewall 100 is further provided with numerous elongated ribs 121, 122, 123 as shown in
[0132] The elongated ribs 121, 122, 123 are of rather straight shape, which is beneficial for a demolding when the workpiece carrier 10 or tray is manufactured as a one-piece injection molded plastic body 11.
[0133] As further illustrated in
[0134] The orientation of the second workpiece carrier 10′ as illustrated in
[0135] As it is further apparent from
[0136] As further illustrated in
[0137] In the example of
[0138] As it is apparent from the illustration of
[0139] Presumed that the first and second workpiece carriers 10, 10′ are arranged next to each other in the same orientation, the crossbeams 125 of the first workpiece carrier 10 will be located directly opposite and adjacent to the crossbeams 126 of the second workpiece carrier 10′. Then and when facing towards each other the crossbeams 125, 126 form an X-shaped structure between first and second workpiece carriers 10, 10′. The crossbeams 125, 126 of first and second workpiece carriers 10, 10′ even mutually abut even when there should be an alignment mismatch with regards to the first direction or second direction (X, Y). With the crossbeams 125, 126 a mutual intrusion or at least partial overlapping of the sidewall 100 of the first workpiece carrier 10 with the sidewall 100 of the second workpiece carrier 10′ can be effectively prevented.
[0140] Generally it is sufficient, when only one sidewall section 142 is provided with only one type of crossbeams 125 and when the oppositely located sidewall portion 143 is provided with a longitudinally extending rib 121, 122, 123 that overlaps with the crossbeam 125 when the first and the second workpiece carriers are arranged next to each other such that the crossbeam 125 faces the respective rib(s) 121, 122, 123.
[0141] In the further illustration of
[0142] The lower portion 28 is a rather straight extension of a first compartment 25 extending straight through the upper portion 26 and into the lower portion 28. The compartment 25 is separated from further compartments 27, 29 by a separation wall 56, 59. The separation wall 59 divides the upper part 26 of the cavity 14 into an upper and a lower half. The lower half is separated by a further separation wall 56. The two separation walls 56, 59 may be regarded as portions of a single T-shaped separation wall.
[0143] The separation wall 59 is terminated in a downward direction by a bottom section 57, 58. The bottom section 57 is an upper plateau and the bottom section 58 is a lower plateau is located in the first compartment 25 and forming a stepped down portion towards the lower part 28 of the cavity 14.
[0144] The separation wall 56 divides the upper part 26 of the cavity 14 into a second compartment 27 and a third compartment 29. Both compartments 27, 29 feature a common depth and terminate in downward direction at the bottom section 57.
[0145] Typically, the separation walls 56, 59 extend towards the upper opening of the cavity 14. The particular shape of the lower port part 28 provide an accommodation space for a dedicated component 60 of the drug delivery device 1. The component 60 comprises a tubular shaped sleeve portion 61 and a semicircular shaped longitudinal extension 62. The longitudinal extension 62 is particularly dedicated for insertion into the semicircular shaped lower part 28 of the cavity 14. The separation wall 56 effectively prevents a misaligned insertion of the device component 60 and/or of its longitudinal protrusion 61 into one of the second and third compartments 27, 29. Moreover, the first compartment 25 is complementary shaped to the shape and geometry of the protrusion 62 of the device component 60. It allows and supports insertion of the device component 60 in one predefined orientation.
