Description

Technical Field

[0001] The present invention relates generally to medical devices, and more particularly to tamper-proof labels for hard-box packaging products of sterile packages of needle assemblies used in medical injection devices. Safety needle assemblies are well known and widely used. Typically, the safety needle assembly includes a hub having a proximal end for connection to a syringe. Prior to use, the assembly is stored in the package under sterile conditions. Background Art

[0002] The solution of blister packs is well known. In use, the user (e.g. a caregiver) partially opens the blister to free the hub and then holds the assembly at the package to connect the hub to the syringe to avoid contamination of the needle assembly or possible sterility breach. The user then further removes the package to free the safety needle assembly. This process is quite complex and prone to user error.

[0003] The rigid box packaging product including the lid portion and the box portion may be used as an alternative packaging solution that is generally more compatible with high-speed automated packaging processes than blister packaging.

[0004] However, a relatively more rigid housing may be more challenging to provide a reliable indicator that assures the end user that the package has not been tampered with or opened prior to final use. For example, without specific measures, an opened package may be attempted to be reclosed by repositioning the lid portion onto the box portion.

[0005] Therefore, there is still a need for solutions that provide tamper-resistant packaging to ensure the sterility of the product to the end user. In particular, there is still a need for a solution that irreversibly provides a highly visible indication of an opening event while maintaining compatibility with automated machine packaging processes. JP2013189241A shows a container that is divided into a body and a cover, and a label is attached to the border where the body and the cover are connected. The label has a lower seal covering the border and a peelable upper seal.

[0006] EP1631388A1 describes an intradermal needle comprising a needle cannula assembly and a protective cover having a limiter portion, the protective cover having a front cover and a rear cover for protecting the needle cannula before and after use. US2016030677A1 shows a method and system for an injection system comprising a container for a drug and a plunger rod having a cover, the container being sealed with a plunger having a push surface, the cover extending from the proximal end of the container. US20040175527A1 discloses a polymer film having a perforated portion of a particular structure and arrangement, the perforated portion enabling controlled tear propagation along a desired tear path. Summary of the invention

[0007] The present disclosure is intended to alleviate one or more of the above-mentioned disadvantages. Aspects of the present disclosure relate to a packaged needle assembly product. In particular, the packaged needle assembly product includes a hard shell packaging product, which includes a box portion and a cover portion, and the box portion and the cover portion are arranged in an assembled configuration to form a shell for the needle assembly. In order to make the shell sealed and closed, the packaged needle assembly product also includes an adhesive label. The adhesive label is fixed to the outer surface of the shell, wherein the label extends over at least a portion of the gap between the cover portion and the box portion. The adhesive label is generally located on the circumference between the edge of the cover portion and the edge of the box portion.

[0008] The label includes a perforated section including a plurality of perforated lines. The perforated lines are arranged at an angle relative to the gap. The perforated section extends across the gap from a first end across the gap to a second end, the first end terminating at or exceeding a first boundary of the gap (e.g., an edge of the cover portion), and the second end terminating at or exceeding a second boundary of the gap (e.g., an edge of the box portion).

[0009] As will be described in detail below, the label provides tamper resistance which assures the end user of the quality of the packaged product.It has been found that the plurality of perforation lines provide an effective visual indication of a previous opening event or attempt to reclose the package by the presence of a tear mark such as a draw strip.

[0010] Preferably, the perforation line is arranged at an angle θ relative to the circumferential gap, the angle being in the range of 20 to 40 degrees, more preferably between 25 to 35 degrees, most preferably about 30 degrees, for example 28 to 32 degrees. It is found that an angle of 20 to 40 degrees constitutes a good range for tear propagation, thereby forming a highly visible draw when opened. Therefore, the inclination (180°-θ) of the perforation line defined by a positive angle less than 180 degrees measured counterclockwise from the gap to the perforation line is preferably within 140 to 160 degrees, more preferably between 145 to 155 degrees, most preferably about 150 degrees, for example 148 to 152 degrees. As will be described in detail below, the applicant has found that the designated perforation portion presents the best effect in terms of optimizing the visibility of the tear mark, the stability of the label before and during the assembly of the label to the packaged product, and providing an optimized user experience for the range of forces required to approach the packaged product.

[0011] Preferably, the length of the label and perforated section is at least 50%, preferably at least 80%, of the length of the perimeter of the housing at the gap. The larger the label, the more securely the cover is fixed to the box, and the more potential space on the label can be used for product information and / or user instructions. The label can be longer than the perimeter of the housing so that the label wraps around itself.

[0012] Preferably, the perforation lines are separated from adjacent perforation lines by a distance of ≤ 1 mm, preferably in the range of 0.7 mm to 0.9 mm. It was found that larger spacings require increasingly larger tearing forces and result in a less predictable quality of the tear pattern formed. It was found that smaller spacings increasingly result in an overall fragility of the entire label before or during (machine) application to the cover and box parts.

[0013] Preferably, the length of the perforation and the width of the perforation section in a direction orthogonal to the dividing line between the cover part and the box part are such that the line can cover manufacturing tolerances.

[0014] Preferably, the perforations extend across the gap at a distance of at least 0.1 mm at both ends. Most preferably, the perforations extend across the gap at at least 0.5 mm at at least one end. The longer the overlap, the more visible the tear mark. To mitigate the weakening of the label, preferably the perforated section does not extend more than 50% of the total height of the label. Machine processing of labels with non-perforated borders of about 1 mm (top, bottom and sides) was confirmed.

[0015] Preferably, all perforations are arranged substantially in parallel within a single row. Other arrangements including perforations in two or more rows, arrangements with intersecting perforations and / or arrangements with perforations extending at different inclinations are less preferred. Additional perforations and / or other configurations have been found to reduce the visibility of the tear pattern and / or reduce the structural integrity of the label, thereby increasing the likelihood of premature tearing or rupture in response to a force applied perpendicular to the label (e.g., during rolling application).

[0016] In a preferred embodiment, the box portion and the cover portion are configured to be slidably engaged into an assembled configuration, and wherein the box portion and the cover portion include circumferentially overlapping side wall segments. Advantageously, the hard shell packaged product may include one or more radial channels extending in a longitudinal direction from the gap between the overlapping side wall segments to provide a gas passage to the interior of the shell.

[0017] The channel can be at least partially defined by one or more protrusions that meet at least one of the following conditions: extending outward from the inner surface of the circumferentially overlapping wall segments of the cover portion toward the corresponding overlapping wall segments of the box portion; and extending outward from the outer surface of the circumferentially overlapping wall segments of the box portion toward the corresponding wall segments of the cover portion.

[0018] Further or additional aspects of the present disclosure relate to a kind of adhesive label for sealing a hard shell packaged product and a roll of backings including a plurality of adhesive labels. Further or additional aspects of the present disclosure relate in particular to a kind of adhesive label for sealing a hard shell packaged product, for example, as disclosed herein, the hard shell packaged product comprising a box portion and a cover portion, the box portion and the cover portion being configured to form a housing for a needle assembly in an assembled configuration, wherein the label is configured to adhere to the outer surface of the housing, and the label is sized to extend across at least a portion of the circumferential gap between the edge of the cover portion and the edge of the box portion, thereby fixing the box portion to the cover portion, and wherein the label comprises a perforated section, the perforated section comprising a plurality of perforated lines, the perforated lines being arranged to pass through the gap at an angle from a first end across the gap to a second end when adhered, the first end terminating at or beyond the edge of the cover portion, and the second end terminating at or beyond the edge of the box portion.

[0029] The terms used to describe specific embodiments are not intended to limit the present invention. As used herein, the singular forms "one", "an" and "the" are also intended to include plural forms, unless the context clearly indicates otherwise. The term "and / or" includes any and all combinations of one or more items of the listed related items. It should be understood that the terms "include" and / or "comprise" indicate the presence of the stated features, but do not exclude the presence or addition of one or more other features. It should be understood that when a specific step of a method is referred to as after another step, the specific step can be performed directly after the other step, or one or more intermediate steps can be performed before performing the specific step, unless otherwise specified. Similarly, it should be understood that when describing the connection between structures or components, the connection can be established directly or through intermediate structures or components, unless otherwise specified.

[0030] As used herein, the term needle assembly may be understood to relate to a needle assembly comprising a hub having a proximal end for connection to a syringe extending in a proximal region of the hub and a needle extending longitudinally from a distal end of the hub in a distal region of the hub.

[0031] The needle assembly usually includes at least one sleeve (also referred to as a needle) extending from the needle hub to receive the corresponding counterpart of the syringe. Preferably, the needle assembly is a safety needle assembly, which includes a protector and a sheath, the protector is usually implemented as a longitudinally extending sleeve, the sleeve can be engaged on the needle, and the sleeve can be removably connected to the hub at the end of the sleeve, and the sheath is pivotally connected to the hub. The sheath usually has two side walls connected by a rear wall, and the rear wall defines a receiving space for receiving the needle between the two side walls. The sheath can pivot between the starting position where the sheath is disengaged from the needle, the use position where the sheath pivots away from the needle and exposes the needle, and the locking position where the sheath is locked to fix the needle to the receiving space. In the locked position, the sheath protects the needle from accidental contact, contamination, needle stick injury, etc. after use. In the locked position, the needle is accommodated in the receiving space of the sheath to be surrounded by the sheath, so the sheath covers the needle.

[0032] Although not exclusively, the packaging product is particularly beneficial for safety needle assemblies, such as those described in full detail in patent PCT / EP2021 / 063205, which is incorporated herein by reference.

[0033] The safety needle assembly preferably comprises a hub, a needle and a sheath, the hub having a proximal end for connecting to a syringe extending in a proximal region of the hub, the needle extending longitudinally from the distal end of the hub in a distal region of the hub, the sheath being pivotally connected to the hub, the sheath having two side walls connected by a rear wall, the rear wall defining between the two side walls an accommodation space for accommodating the needle, wherein the sheath can be adjusted between a starting position in which the sheath is approximately in the distal region of the hub, a use position in which the sheath is approximately in the proximal region of the hub, and a locking position in which the sheath (protector) is locked to fix the needle in the accommodation space, wherein in the starting position the sheath extends longitudinally from the hub, wherein the hub is provided with at least one first mating element and the sheath is provided with at least one second mating element, wherein in the locking position of the sheath the first mating element and the second mating element engage with each other to lock the sheath, characterized in that in the starting position the first mating element and the second mating element contact each other to define the starting position of the sheath.

[0034] By arranging the sheath extending longitudinally from the hub at the starting position, therefore for packaging purposes, the occupied space of the safety needle assembly at the starting position becomes much smaller, so that there are different types of packages and / or more effective packages and / or transportation and / or storage. For example, it is possible to consider this reduced occupied space (hard box package), so that the safety needle assembly of packaging can be automatically processed. However, the automatic processing of the blister pack assembly is actually impossible, which causes the blister pack assembly to be manually collected in a box for transportation and storage. This limits the speed of the assembly line. By arranging the sheath at the longitudinal extension position of the hub at the starting position, a more compact arrangement of the safety needle assembly can be obtained, so that there is a hard box package. This hard box package can be automatically processed, so that the speed of the assembly line is improved, so that the safety needle assembly is more effectively produced, packaged, transported and / or stored. In addition, by using a hard cover, the working mode of the needle assembly is kept unchanged. This is beneficial to the user because he can follow the process he is used to. When the cover of the hard box is removed, the hub of the needle assembly becomes exposed and can be connected to a syringe without compromising sterility and avoiding possible contamination. When the hub of the needle assembly is connected to the syringe, the hard case can be removed from the needle assembly and the shield can be pivoted to the use position to prepare the needle with the syringe for use.

[0035] The hard shell preferably comprises or consists essentially of a medical grade composition, preferably an injection moldable plastic composition, such as polypropylene.

[0036] Label as described herein generally comprises substrate and adhesive portion known in the art. Adhesive portion is pressure-sensitive adhesive composition normally. Other adhesive portions can be used, for example temperature-sensitive or radiation-curable adhesive portions. Advantageously, the pressure-sensitive adhesive portion enables machine application, positioning and provides adhesive pressure (for example, by roller).

[0037] The present invention is described more fully below with reference to the accompanying drawings, in which embodiments of the invention are shown. In the accompanying drawings, the absolute and relative sizes of systems, components, layers and regions may be exaggerated for clarity. The embodiments may be described with reference to schematic and / or cross-sectional views of possible idealized embodiments and intermediate structures of the invention. In the specification and drawings, the same reference numerals always refer to the same elements. Relative terms and derivatives of these terms should be interpreted as referring to the orientation as described at the time or the orientation shown in the drawings being discussed. These relative terms are for ease of description and do not require that the system be constructed or operated in a specific orientation unless otherwise specified.

[0038] Figure 1AAn exemplary embodiment of a packaged needle assembly product 100 is shown. The packaged needle assembly product comprises a hard shell packaging product that forms an outer shell for the needle assembly. The hard shell packaging product 1 comprises a box portion 2 and a cover portion 3 that are arranged in an assembled configuration to form an outer shell for the needle assembly. A dividing line or gap 'g' is formed between the cover portion and the box portion.

[0039] The packaged needle assembly product includes an adhesive label 13 affixed along the outer surface of the housing (see, e.g., Figure 2B ), wherein the label extends over at least a portion of the circumferential gap g between the edge 3e of the lid and the edge 2e of the box, thereby securing the lid to the box and providing a seal on the hard shell packaged product 1. Figure 2A , Figure 2B and Figure 2C Explain the details about the tag.

[0040] In a preferred embodiment, for example, Figure 1B , Figure 1C and Figure 3C As shown, the box portion 2 and the cover portion 3 are configured to be slidably engaged into an assembled configuration. The box portion and the cover portion include circumferentially overlapping side wall sections 20, 30.

[0041] Advantageously, the hard shell packaged product 1 may comprise one or more radial channels 5 extending in the longitudinal direction between the overlapping side wall sections to provide a gas passage P to the interior of the shell.

[0042] Advantageously, providing a gas passage to the enclosed volume enables sterilization of the packaged product (e.g., needle assembly). As will be described in detail below, advantageously, the packaged product enables gas to enter the needle assembly for sterilization by a gaseous agent while being enclosed by the cover and the box. Preferably, one or more passages form a unique passage between the internal volume and the environment. By extending the passage between the inner surface of the cover and the outer surface of the box (or the inner surface of the box and the outer surface of the cover) a distance, such as a pre-designed engagement distance, re-contamination of the needle assembly by airborne infectious agents is mitigated.

[0043] In some embodiments, for example as shown in the figure, the channel 5 is at least partially defined by one or more protrusions 7 (e.g., ribs), which meet at least one of the following conditions: extending outward from the inner surface of the circumferentially overlapping wall segments of the cover portion toward the corresponding overlapping wall segments of the box portion; and extending outward from the outer surface of the circumferentially overlapping wall segments of the box portion toward the corresponding wall segments of the cover portion.

[0044] like Figure 1BAs seen in more detail in , advantageously, the spacer can define the cross-sectional dimensions of the channel. The channel length can be understood to be defined to a great extent by the overlapping distance between the cover and the box. The length L1 of the overlap is usually ≥2mm. The longer the overlap, the more complicated the path for pollutants to enter. In principle, the overlap can be larger. The longer the overlap, the more stable the cover is positioned on the box. For example, the overlap L1 can be up to about 20mm, for example in the range of 2mm to 20mm or in the range of 3mm to 10mm. Preventing re-contamination is considered to be related to providing a channel for stagnant air. It is found that an overlap of 2mm can prevent re-contamination. In fact, the length L1 of the overlap is between 5mm and 10mm, for example, about 8mm. The range between 5mm and 10mm is considered to be the optimal range between the compactness and stability of the cover on the box. Preferably, the width of the channel (the distance between the opposite sides) is as thin as possible while enabling gas to pass. Typically, the distance 'd' between the opposite sides is less than 1mm. In principle, the spacing can be larger, for example up to 2 mm or even 3 mm or more. The thinner the channel, the more compact the packaged product. Preferably, the spacing 'd' ≤ 0.5. More preferably, d ≤ 0.3 mm, for example about 0.2 mm. The wider the channel, the greater the path for potential recontamination and the less compact the packaged product. A spacing of about 0.05 mm has been found to be sufficient.

[0045] In a preferred embodiment, for example as shown in the figure, the projection forms the only contact between the relative side wall surfaces of the box portion and the cover portion. This limits the area of ​​flush contact between the cover portion and the box portion to point contact or line contact defined by the projection basically.

[0046] In some embodiments, for example, Figure 1C and Figure 3C As shown, one or more additional spacers 7a are provided between the opposing surfaces of the cover portion 3f and the box portion 2f to ensure an axial gap between the cover portion and the box portion in the closed state, for example Figure 1A and Figure 3C shown.

[0047] In order to prevent the needle assembly 100 from rotating internally within the cassette portion 3, one or more inwardly extending ribs 71 or slots may be provided (see, for example, Figure 1C and Figure 3C ), the rib or slot engages with the needle assembly 100, such as the hub 102 shown.

[0048] The box portion and / or the cover portion may include a flat portion (eg as shown in the figures). The flat portion prevents the product from rolling, for example, along a tabletop.

[0049] To facilitate removal of the cover, the cover and / or the box may be provided with one or more external members for manual gripping, such as Figure 1B The ribs 9 are shown.

[0050] Box and lid as disclosed herein can be particularly useful for packaging products in sterile packages ready for direct use by end users. Advantageously, the packaged product enables sterilization of the product in the packaged state while providing effective tamper protection by providing one or more of the components of a visual indication of an opening event.

[0051] Figure 2A A section of a backing 201 including a plurality of labels 13, 13-n is shown. To facilitate opening and form a highly visible tear mark 13r, the label includes a perforated section 50. The perforated section is sized to overlap the location of the parting line or gap g between the lid and box portions. The width of the perforated section 50 is sized to cover the overlap of the perforated section with the parting line including a manufacturing tolerance Tg.

[0052] Figure 2B A packaged needle assembly product 100 (e.g., with Figure 1A The product shown in FIG. 1 is a partial view of the same product as the product shown in FIG. 1 , the packaged needle assembly product also includes a label as disclosed herein. As indicated, the perforated portion overlaps the dividing line or gap g within the manufacturing tolerance.

[0053] The label is fixed across the circumferential gap (g) between the cover and the box (indicated by the line). The label fixes the cover to the box. In order to access the packaged product, the user removes the cover from the box (e.g., by pulling and / or twisting). This can cause irreversible damage (tearing) of the label.

[0054] like Figure 2C As further shown, the perforated section 50 includes a plurality of perforated lines 51. These lines cross the gap at an angle (θ) from a first end 51-1 across the gap to a second end 51-2 across the gap, the first end terminating at or beyond the edge of the lid portion, and the second end terminating at or beyond the edge of the box portion.

[0055] The perforation line is arranged at an angle (θ) relative to the circumferential gap (g) in the range of 20 to 40 degrees. In a preferred embodiment, such as shown in the figures, the angle θ is about 30°.

[0056] The length L13 of the label is generally in the range of 80% to 120% of the circumference of the hard shell packaged product at the dividing line.

[0057] The perforated lines 51 are separated from adjacent perforated lines by a distance of ≤ 1 mm, preferably in the range of 0.7 mm to 0.9 mm. The perforated portion may be suitably manufactured as known in the art, for example it may be a rotating drum with blades.

[0058] Preferably, the perforations extend across the gap at both ends by a distance s50 of at least 0.1 mm.The label sections 53, 54 above and below the perforated sections may include one or more data display areas for product information and / or user instructions.

[0059] The length L13 and height h13 of the label, the width L2 of the perforated section, and the length L51 of each perforated section depend on the size of the cover, the size of the box, the width of the gap g, and the manufacturing tolerance Tg. In some embodiments, for example, as shown in the figure, the length L51 can be, for example, 3mm to 5mm. The width L2 of the perforated section can be, for example, 1mm to 3mm.

[0060] User testing studies have shown that arranging the perforations at an angle consistently results in the formation of highly visible tear marks, regardless of whether the user is left-handed or right-handed, regardless of whether the user is moving only the lid portion, only the box portion, or both the lid portion and the lid portion, and the angle is in the range of 20 to 40 degrees, preferably in the range of 25 to 35 degrees, and most preferably about 30 degrees. The preferred right-hand orientation of the perforation line 51 relative to the parting line meets the user's desire to apply an opening force in a counterclockwise direction.

[0061] User studies further demonstrated that, advantageously, tags as disclosed herein enable control of the force or torque experienced by a user to open a product.

[0062] Figure 3A An exemplary embodiment of a hard shell packaged product that has been sealed by a label as disclosed herein after opening the housing, removing the packaged needle assembly, and repositioning the cover is shown. Figure 3B A comparative example of the same hard shell packaged product is shown before (left) and after (right) opening and reclosing, whereby the label is provided with a perforation line 51' extending parallel to the dividing line between the lid and box parts. As can be seen, the opening of the product that has been sealed with a label as disclosed herein can be clearly seen by the presence of multiple tear marks 13t (drawing edges), while the comparative example results in a clean tear, which enables the package to be visually reclosed after the initial opening due to the absence of clear tear marks.

[0063] For the sake of clarity and concise description, the features are described herein as part of the same or separate embodiments, however, it should be understood that the scope of the invention may include embodiments having a combination of all or some of the described features. Of course, it should be understood that any of the above embodiments can be combined with one or more other embodiments to provide even further improvements in finding and matching designs and advantages.

[0064] In interpreting the appended claims, it should be understood that the word "comprising" does not exclude the presence of other elements or actions than those listed in a given claim; the word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements; any reference numerals in a claim do not limit the scope of the claim; multiple "components" may be represented by the same or different items or structures or functions implemented; any disclosed device or part of a device may be combined together or divided into further parts, unless otherwise specified. Where one claim refers to another claim, this may indicate synergistic advantages achieved by combining the respective features of the claims. The fact that certain measures are listed in mutually different claims does not indicate that a combination of these measures cannot also be used to advantage. Therefore, the present embodiment may include all working combinations of the claims, where each claim may in principle refer to any previous claim unless the context clearly excludes it.
