Abstract
Description
Technical Field
[0001] This invention relates to glass containers, including glass container systems comprising containers, stoppers, and / or lids, and methods for manufacturing the containers and systems. Background Technology
[0002] Pharmaceutical compositions of biological agents, such as protein and nucleic acid formulations, are prone to degradation. Complex measures are required to reduce their degradation tendency during storage or transportation. This is particularly important for aqueous compositions that allow enzymatic degradation as well as a wide range of chemical processes, including hydrolysis.
[0003] Novel and complex drug delivery systems, such as liposomes or lipid nanoparticles, increase the number of components in a composition, making it more difficult to predict and prevent potential undesirable deterioration.
[0004] Furthermore, pharmaceutical companies are under immense pressure to introduce new and robust treatment principles to the public without time to optimize or even test the long-term storage performance of their new drug products. Therefore, there has always been a need for a way to prevent degradation, or, at critical moments, a way to safely and reliably prevent degradation for a sufficient period of time, securely package and store even the most complex pharmaceutical compositions.
[0005] Freeze-drying (also known as lyophilization) has been used to address several issues. It is a well-known method that creates an environment unfavorable to enzyme activity while preventing hydrolysis. However, freeze-drying is a costly method, and finding the optimal excipients and redispersibility schemes can be difficult and time-consuming. Furthermore, freeze-drying does not produce ready-to-use compositions. Freeze-dried compositions must be redispersed before use, a process that carries the risk of human error, resulting in incomplete or incorrect dissolution, which could harm patients and reduce acceptability.
[0006] A solution to the above problems is urgently needed. Summary of the Invention
[0007] In a first aspect, the present invention relates to a glass container for a pharmaceutical composition, comprising a hollow cylinder having at least one open end. wherein at least a portion of the surface of the glass container comprises a coating having a glass transition temperature below -60°C.
[0008] It has been found that coatings with glass transition temperatures below -80°C can achieve exceptionally tight seals at very low storage temperatures. Maintaining a tight seal at such low temperatures has always been a challenge. For example, at very low temperatures, the seal of conventional silicone oil coatings can be compromised, allowing foreign matter to enter the hollow body. This foreign matter may react with or alter the components within the container or system, compromising sterility. The containers and systems of the present invention can store even the most sensitive pharmaceutical compositions, including those containing protein or nucleic acid active ingredients, at very low temperatures. By slowing down or stopping chemical and enzymatic reactions, freezing and storing pharmaceutical compositions at very low temperatures (e.g., -80°C) avoids undesirable degradation. Most importantly, storage at -80°C is suitable for ready-to-use compositions, for example, in pre-filled syringes. The inventors hypothesize that coatings with glass transition temperatures below -60°C retain sufficient elasticity at low temperatures to form a tight seal between the container surface and container closure devices such as stoppers or caps. For example, the coating may be present on at least a portion of the inner surface of the hollow cylinder to form a tight seal between the inner surface and the stopper. Additionally or alternatively, the glass container of the present invention may be configured to be closed by a lid and have a fitting surface at the open end B, said fitting surface being configured to fit tightly against the surface of the lid. Wherein, at least a portion of said fitting surface comprises the coating.
[0009] In a second aspect, the present invention relates to a glass container for a pharmaceutical composition, comprising a hollow cylinder having at least one open end. At least a portion of the surface of the glass container includes a coating having a certain hardness such that the hardness value measured on the coated surface of the glass container according to DIN EN ISO 14577-1:2015-11 and DIN EN ISO 14577-4:2017-04 differs from the hardness value measured on its uncoated surface by less than 10%.
[0010] The inventors have discovered that low-hardness coatings maintain a tight seal even at very low storage temperatures. In hardness tests, the soft, thin layer produces hardness values very close to those of the substrate. In other words, the coating is softer than the substrate (i.e., the glass of the glass container). Maintaining a tight seal at such low temperatures has always been a challenge. For example, at very low temperatures, the seal of conventional silicone oil coatings is compromised, allowing foreign matter to enter the hollow body. This foreign matter may react with or alter the components within the container or system, compromising sterility. The containers and systems of the present invention can store even the most sensitive pharmaceutical compositions, including those containing protein or nucleic acid active ingredients, at very low temperatures. By slowing down or stopping chemical and enzymatic reactions, freezing and storing pharmaceutical compositions at very low temperatures (e.g., -80°C) avoids undesirable degradation. Most importantly, storage at -80°C is suitable for ready-to-use compositions, such as in pre-filled syringes. The inventors have also discovered that coatings with suitable hardness at 20°C can maintain sufficient elasticity to form a tight seal between the container surface and container closure devices such as stoppers or caps. For example, the coating may be present on at least a portion of the inner surface of the hollow cylinder to form a tight seal between the inner surface and the stopper. Additionally or alternatively, the glass container of the present invention may be configured to be closed by a lid and have a fitting surface at the open end B, said fitting surface being configured to fit tightly against the surface of the lid. Wherein, at least a portion of said fitting surface comprises the coating.
[0011] In a third aspect, the present invention relates to a glass container for a pharmaceutical composition, comprising: a hollow cylinder having at least one open end. At least a portion of the surface of the glass container is coated, and the container has container seal integrity in a standard ethanol-modified dye invasive test for at least 150 hours at -80°C. The container seal integrity in the standard ethanol-modified dye invasive test may be related to a stopper and / or a tip.
[0012] This fully ensures that glass containers with this standard ethanol-modified dye invasiveness test provide a tight seal, even under very low temperature storage conditions. The sterile composition remains sterile, and foreign matter will not leach into the composition within the container or system.
[0013] In a fourth aspect, the present invention relates to a glass container for a pharmaceutical composition, comprising a hollow cylinder having at least one open end. At least a portion of the surface of the glass container has a coating having a thickness of at least 400 nm, and the coating is cured at a temperature below 150°C, particularly at 50°C to less than 110°C.
[0014] The inventors have discovered that both coating thickness and curing temperature affect the performance of the seal at extremely low temperatures. In particular, the curing temperature should not be too high to avoid undesirable chemical reactions, such as excessive crosslinking or polymerization. In some cases, coatings cured at very high temperatures lack sufficient elasticity at low temperatures to maintain a tight seal; furthermore, slippage forces increase at high curing temperatures.
[0015] In a fifth aspect, the present invention relates to a glass container for a pharmaceutical composition, comprising a hollow cylinder having an open end A configured to receive a stopper slidable from the open end A relative to the hollow cylinder. At least a portion of the inner surface of the hollow cylinder has a coating, wherein the ratio of the total inner diameter variation along the coated portion of the inner surface to the thickness of the coating is less than 500.
[0016] The significant variation in the inner diameter of a hollow cylinder makes sealing any gaps between the plug and the inner surface of the body more difficult. Keeping the ratio low allows for a tight seal even at low temperatures. If the variation in inner diameter is not particularly small, an additional coating thickness of appropriate coating material can also help to achieve a tight seal even at low storage temperatures.
[0017] In a sixth aspect, the present invention relates to a glass container for a pharmaceutical composition, comprising a hollow cylinder having at least one open end. At least a portion of the surface of the glass container comprises a coating having a crystallization temperature range and a melting temperature range determined using differential scanning calorimetry at a temperature change rate of 10°C / min. The crystallization temperature range and the melting temperature range overlap at temperatures ranging from -75°C to -100°C, particularly at -80°C.
[0018] Not wanting to be bound by this theory, the inventors believe that both crystalline and molten portions of the coating exist within the overlap area. This is thought to impart the mechanical resistance and elasticity required for the coating to form a tight seal at low temperatures.
[0019] In a seventh aspect, the present invention relates to a glass container for a pharmaceutical composition, comprising a hollow cylinder having at least one open end. At least a portion of the surface of the glass container comprises a coating comprising one or more cross-linked polysiloxane structural units and one or more non-cross-linked polysiloxane structural units. The weight ratio of the cross-linked polysiloxane structural units to the non-cross-linked polysiloxane structural units in the coating is less than 3.00, and optionally at least 0.40.
[0020] Non-crosslinked polysiloxane structural units can help achieve the desired elasticity and cryogenic sealing properties, which is preferred for the containers and systems of the present invention. The inventors believe that crosslinked polysiloxanes provide a polymer network in which non-crosslinked polysiloxanes remain embedded, thereby creating a hybrid coating structure that combines the properties of a cured polymer network and liquid silicone oil. This is believed to contribute to achieving a tight seal at cryogenic temperatures.
[0021] According to an eighth aspect, the present invention provides a system comprising a glass container, stopper, and / or lid as described in any one of the first to seventh aspects, wherein the system has container seal integrity in a specific ethanol-modified dye invasive test for at least 150 hours at -80°C. This container seal integrity in the specific ethanol-modified dye invasive test may be related to the stopper and / or tip.
[0022] This fully ensures that systems with this specific ethanol-modified dye invasiveness test provide a tight seal, even under very low temperature storage conditions. The sterile composition remains sterile, and foreign matter will not penetrate the composition within the system.
[0023] In a ninth aspect, the present invention relates to a system comprising a glass container and a stopper as described in any one of the first to seventh aspects, wherein the ratio of the difference (I) between the average linear coefficient of thermal expansion of the material of the stopper and the material of the glass container to the thickness (II) of the coating is less than 0.5 ppm / nm.
[0024] The coefficient of thermal expansion of the stopper material can be much higher than that of the glass container. It has been found that by selecting the coating thickness based on the difference in thermal expansion coefficients between the stopper and container materials, a tight seal can be guaranteed even at very low storage temperatures.
[0025] The tenth aspect of the invention relates to a method of manufacturing a glass container according to any one of the first to seventh aspects, comprising: melting a batch of raw materials to prepare glass; forming the glass into a glass container; coating a coating composition; and curing the composition at a curing temperature below 150°C, particularly between 50°C and less than 110°C. Similarly, the seventh aspect includes a method of manufacturing a system according to the fifth or sixth aspect of the invention by adding the further step of inserting a stopper and optionally a plunger rod into a hollow cylinder.
[0026] In the eleventh aspect, the present invention relates to a glass container according to the first to fourth aspects of the invention or a system according to the eighth or ninth aspect of the invention, comprising a pharmaceutical composition.
[0027] In a twelfth aspect, the present invention relates to the use of a coating composition for preparing a coating on the surface of a glass container, wherein the coated glass container is subsequently stored for at least 150 hours at a temperature range below -60°C, particularly at a low temperature of about -80°C, wherein the coating composition comprises, by weight percentage: One or more non-crosslinkable polysiloxane compounds 2.0% to 25.0% One or more cross-linked polysiloxane compounds 0.10% to 1.50% One or more catalysts 0.03% to 0.50% One or more diluents 55.0% to 92.0%
[0028] In a thirteenth aspect, the present invention relates to the use of glass containers according to the first to seventh aspects of the invention or systems according to the eighth or ninth aspect of the invention for storing pharmaceutical compositions for at least 150 hours at temperatures below -60°C, particularly at about 80°C.

Additionally or alternatively, the glass container according to the invention may have an open end that can be closed by a cap. In a syringe, the second open end or open end B (the first open end or open end A being the opening for receiving the stopper) is typically the tip side, i.e., the portion of the syringe to which the injection needle is attached. Open end B is typically located at the other end of the container compared to open end A. Open end A may be referred to as the "stopper side," i.e., the side into which the stopper can be inserted. The inventors have found that providing a coating on the tip side improves sealing even at extremely low temperatures.
[0038] In embodiments, the hollow cylinder described herein as part of a glass container or system may have a substantially constant inner diameter so that the stopper can substantially expel all the composition present in the cylinder. In this document, "substantially constant" means an inner diameter variation of no more than 200 μm, no more than 100 μm, or no more than 50 μm.

Preferably, the hardness value of the coated surface is lower than that of the uncoated surface, optionally by less than 10%, less than 7.0%, less than 5.0%, or less than 3.0%.

[0061] The coating may be applied to the inner surface of the hollow cylinder of the glass container and / or one or more other surfaces of the glass container, wherein the other surfaces include the surface of the tip in a syringe, such as the mating surface on the tip side of the syringe. The coating and paint compositions described herein facilitate achieving a tight seal at low temperatures.
[0062] The coating thickness can be greater than 350 nm, greater than 400 nm, greater than 450 nm, or greater than 500 nm. Optionally, the coating thickness can be up to 1500 nm, up to 1250 nm, or up to 1000 nm. Appropriate coating thickness helps achieve a tight seal at low temperatures. In embodiments, the coating thickness can be from 350 nm to 1500 nm, from 400 nm to 1250 nm, or from 450 nm to 1000 nm. Optionally, the above-mentioned indices for coating thickness mean that at least 90%, at least 95%, or at least 99% of the coating area has a coating thickness within the indicated range. In a preferred embodiment, the coating thickness is greater than 400 nm, particularly at least 450 nm or at least 500 nm. Exemplary preferred ranges for coating thickness are greater than 400 nm to 1500 nm, or 450 nm to 1250 nm or 500 nm to 1000 nm.
[0063] The coating may comprise one or more organosilicon polymers. An organosilicon polymer is a polymeric material composed of monomeric units comprising silicon (Si) and carbon (C) atoms. An example of an organosilicon polymer is a polysiloxane. In embodiments, the coating comprises one or more polysiloxane structural units. A "polysiloxane structural unit" may refer to a polysiloxane structure within a macromolecule (e.g., covalently bonded to or part of a macromolecule) or the polysiloxane molecule itself. For example, a crosslinked polysiloxane structural unit is part of a polymeric network (covalently linked); while a non-crosslinked polysiloxane structural unit exists as a molecule in the coating and is not covalently linked to other molecules in the coating. Therefore, the coating may comprise crosslinked and / or non-crosslinked polysiloxane structural units. In this document, "crosslinked" means that the polysiloxane structural unit is covalently linked to the polymeric network. Specifically, the term "crosslinked" includes the preferred case where the polysiloxane structure is covalently linked to other polysiloxane structures, for example, through a polymeric backbone. Optionally, the crosslinked polysiloxane structural units are covalently bonded to other polysiloxane structures as a result of hydrosilylation. For example, the polymeric backbone can be formed by polymerizing a polysiloxane carrying polymerizable functional groups (such as vinyl groups). Conversely, "non-crosslinked" means that the polysiloxane is not covalently linked to other polysiloxane structures through the polymeric backbone, or preferably not at all covalently linked to other polysiloxanes in the coating.
[0064] In one embodiment, the crosslinked polysiloxane structural unit is crosslinked via one or more (e.g., two) terminal groups. These terminal groups may be selected from vinyl, propenyl, methacryl, styrene, and combinations thereof. In one embodiment, the coating comprises a crosslinkable polysiloxane compound and a hydrosilylation product of the crosslinkable polysiloxane compound, such as a vinyl polysiloxane compound and a polysiloxane having at least two Si-H groups. The crosslinkable polysiloxane can be crosslinked with the crosslinkable polysiloxane by reacting its multiple Si-H groups with the vinyl groups of the crosslinkable polysiloxane. This reaction may be platinum-catalyzed.
[0065] In this invention, "polysiloxane" or "polysiloxane structural unit" can refer to a polyalkylsiloxane structural unit, such as a polydialkylsiloxane structural unit. Optionally, one or more hydrocarbon groups in the polyalkylsiloxane or polydialkylsiloxane are independently selected from branched or unbranched C1 to C8 hydrocarbon groups. The hydrocarbon group can be a straight-chain hydrocarbon group. For example, the hydrocarbon group can be independently selected from methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, and octyl groups. Preferably, the hydrocarbon group is independently selected from methyl and ethyl groups.
[0066] In one embodiment, the coating comprises crosslinked polydialkylsiloxane structural units and non-crosslinked polysiloxane structural units. Specifically, the coating may comprise crosslinked polydialkylsiloxane structural units and non-crosslinked polysiloxane structural units, wherein the non-crosslinked polysiloxane structural units may be one or more silicone oils, i.e., polydialkylsiloxane structural units, such as polydimethylsiloxane silicone oil.
[0067] Optionally, the weight ratio of cross-linked polysiloxane structural units to non-cross-linked polysiloxane structural units in the coating is less than 3.00, less than 2.50, less than 1.80, or less than 1.20. The weight ratio of cross-linked to non-cross-linked polysiloxane structural units in the coating can be at least 0.40, at least 0.60, or at least 0.70. In embodiments, this ratio is from 0.40 to 3.00, 0.60 to 2.50, or 0.70 to 1.80. Non-cross-linked polysiloxane structural units can help achieve the desired elasticity and cryogenic sealing function, which is preferred for containers and systems according to the invention.
[0068] The coating may comprise more than one type of non-crosslinked polysiloxane structural unit, such as at least two or at least three types. These types may differ in viscosity. In some embodiments, the coating comprises: high-viscosity non-crosslinked polysiloxane structural units with a viscosity exceeding 10,000 cSt, and / or low-viscosity non-crosslinked polysiloxane structural units with a viscosity below 10,000 cSt. It may be applied at 23°C and 10s according to DIN EN ISO 3219:1993. -1 The viscosity was measured using a coaxial cylinder system at a shear rate of [value missing]. Optionally, the viscosity of the high-viscosity non-crosslinked polysiloxane structural unit is at least 15000 cSt, and / or the viscosity of the low-viscosity non-crosslinked polysiloxane structural unit is below 5000 cSt.
[0069] In one embodiment, the coating comprises high-viscosity, non-crosslinked polysiloxane structural units, but not necessarily low-viscosity, non-crosslinked polysiloxane structural units.
[0070] The weight ratio (by mass) of low-viscosity non-crosslinked polysiloxane structural units to high-viscosity non-crosslinked polysiloxane structural units. 高 :quality 低 The weight ratio can be at least 0.10, at least 0.50, at least 1.00, at least 1.50, or at least 2.00. In some embodiments, this ratio can be as high as 5.00, 4.00, or 3.00. For example, the weight ratio of low-viscosity non-crosslinked polysiloxane structural units to high-viscosity non-crosslinked polysiloxane structural units can be from 0.10 to 5.00, 0.50 to 4.00, or 1.00 to 3.00.
[0071] Crosslinked polysiloxane structural units, low-viscosity non-crosslinked polysiloxane structural units, and / or high-viscosity non-crosslinked polysiloxane structural units may include or be composed of dialkylsiloxane monomer units, particularly dimethylsiloxane monomer units.
[0072] Optionally, the weight-average molecular weight of the low-viscosity non-crosslinked polysiloxane structural unit is from 1200 g / mol to 30000 g / mol; and / or the weight-average molecular weight of the high-viscosity non-crosslinked polysiloxane structural unit is from 15000 g / mol to 300000 g / mol. In one embodiment, the weight-average molecular weight of the high-viscosity non-crosslinked polysiloxane structural unit is from 32000 g / mol to 210000 g / mol, or from 100000 g / mol to 150000 g / mol. In one embodiment, the weight-average molecular weight of the low-viscosity non-crosslinked polysiloxane structural unit is from 5000 g / mol to 25000 g / mol, or from 10000 g / mol to 20000 g / mol.
[0073] In the embodiments, the weight-average molecular weight of the low-viscosity non-crosslinked polysiloxane structural units is at least 1200 g / mol, at least 5000 g / mol, or at least 10000 g / mol. This weight-average molecular weight can be as high as 30000 g / mol, 25000 g / mol, or 20000 g / mol.
[0074] In the embodiments, the weight-average molecular weight of the high-viscosity non-crosslinked polysiloxane structural units is at least 15,000 g / mol, at least 32,000 g / mol, or at least 100,000 g / mol. This weight-average molecular weight can be as high as 300,000 g / mol, 210,000 g / mol, or 150,000 g / mol.
[0075] Not wanting to be bound by this theory, the inventors believe that the curing temperature of the coating composition is related to achieving a tight seal. The coating can be cured at temperatures below 150°C, below 125°C, or below 110°C. Too high a curing temperature may result in low elasticity of the coating. On the other hand, too low a curing temperature may not be sufficient to achieve good sealing performance. Therefore, in the embodiments, the curing temperature can be above 50°C, above 60°C, or above 70°C. It is important to note that the curing temperature is the effective temperature of the coating composition. It should not be confused with the nominal oven temperature. The oven temperature may be much higher than the curing temperature because there may not be enough time during the curing period for the entire oven to equilibrate at the nominal temperature. Optionally, the curing temperature of the coating can be from 50°C to less than 150°C, from 60°C to less than 125°C, or from 70°C to less than 110°C. Preferably, the curing temperature range is from 50°C to less than 110°C.
[0076] In an embodiment, the coating is obtained or is possible by applying the coating composition disclosed herein to at least a portion of the surface of a container (e.g., the inner surface and / or the mating surface) and curing the coating composition on the surface, wherein the curing temperature of the coating composition is less than 150°C, particularly 50°C to less than 110°C.
[0077] Optionally, the curing temperature can be maintained for at least 10 seconds, at least 30 seconds, at least 45 seconds, or at least 60 seconds. In embodiments, the curing temperature can be maintained for up to 3000 seconds, up to 300 seconds, or up to 180 seconds. Excessive curing time may weaken elasticity and gliding force.
[0078] To achieve a suitable seal, it is generally sufficient to apply the coating to the areas requiring a tight seal, namely the contact area between the inner surface and the stopper, and / or the contact area between the mating surface and the cap. The coating may be applied to at least 25% or at least 50% of the inner surface of the hollow cylinder (area-by-area). However, the coating can also have a beneficial effect on the sliding properties of the stopper on the inner surface of the hollow cylinder. Therefore, in some embodiments, the coating is applied to at least 65% or at least 85% of the inner surface of the hollow cylinder (area-by-area). Optionally, the coating is applied to at least 90% or substantially the entire inner surface of the hollow cylinder. Optionally or additionally, the coating is applied to at least 65% or at least 85% of the mating surface of the glass container (area-by-area). Optionally, the coating is applied to at least 90% or substantially the entire mating surface.
[0079] The glass transition temperature of the coating can be below -60°C, preferably below -70°C, for example below -75°C or below -80°C. Optionally, the glass transition temperature can be above -200°C, above -150°C, above -120°C, or above -100°C. The glass transition temperature can be measured using differential scanning calorimetry (DSC) or thermodynamic analysis (TMA). An exemplary method for determining the glass transition temperature of the coating includes performing thermodynamic analysis in expansion mode, for example, using a Q400 thermodynamic analyzer from TA Instruments. According to the invention, a sample can be prepared by coating a glass container, then the coating can be scraped off with a scalpel, and thermodynamic analysis can be performed in expansion mode, i.e., measuring the relationship between the expansion or contraction of the sample and temperature. In embodiments, the glass transition temperature range of the coating is between -200°C and -60°C, -150°C and -70°C, -120°C and -75°C, or -80°C and -100°C. In one embodiment, the glass transition temperature is -80°C to -90°C.
[0080] The coating can be amorphous or partially crystalline at room temperature. Optionally, the coating has a crystallinity of less than 20% (v / v) at 20°C.
[0081] In an embodiment, the coating may have a crystallization temperature range and a melting temperature range determined using differential scanning calorimetry (DSC) at a temperature change rate of 10°C / min. The crystallization temperature range and the melting temperature range overlap at a temperature range of -75°C to -100°C, particularly at -80°C. For example, DSC can be performed in a temperature range of -120°C to -60°C, and a suitable instrument is a DSC Q2000 (TA instrument).
[0082] Not wanting to be bound by this theory, the inventors believe that within the overlapping range, the coating has both crystalline and molten portions. This allows the coating to be considered to possess the mechanical resistance and elasticity required to form a tight seal at low temperatures. If the peak regions of crystallization and melting extend into the same temperature range, then the crystallization and melting temperature ranges are considered to overlap. For example, crystallization can begin at -55°C and end at -95°C, meaning the exothermic crystallization peak region can be from -55°C to -95°C; melting can begin at -90°C and end at -40°C, meaning the endothermic melting peak region can be from -90°C to -40°C. In this example, the overlapping temperature range is from -90°C to -55°C. This example satisfies the requirement of overlap in temperatures from -75°C to -100°C, because at least one temperature overlaps within the indicated range. Container seal integrity
[0083] Even at very low temperatures, the glass containers and systems according to the invention can maintain significant container seal integrity. Specifically, the container seal integrity under the standard ethanol-modified dye immersion test can be maintained for at least 150 hours at -80°C. This means that the seal integrity of the open end A (related to the stopper) and / or open end B (related to the tip) of the glass container or system provides a very tight seal for at least 150 hours, even at -80°C. The time here refers to the period from immersion to complete equilibrium, during which the container can undergo the appropriate tests without problems, i.e., without dye immersion.
[0084] Optionally, the container seal integrity for the standard ethanol-modified dye invasive test is at least 300 hours, at least 600 hours, or at least 1200 hours at -80°C. These times and temperatures are considered sufficient for the safe production, dispensing, and storage of pharmaceutical compositions in glass containers or systems.
[0085] The container seal integrity of the glass container according to the invention under the standard ethanol-modified dye immersion test at -80°C is at least 150 hours, at least 600 hours, or at least 1200 hours. Preferably, the container seal integrity of the glass container according to the invention under the standard ethanol-modified dye immersion test at -80°C is at least 1500 hours or at least 6000 hours. Depending on the required shelf life of the pharmaceutical product, the container seal integrity under the standard ethanol-modified dye immersion test at -80°C does not necessarily have to be very high; for example, in some embodiments, it can be up to 12000 hours, 10000 hours, or 8000 hours. The container seal integrity under the standard ethanol-modified dye immersion test may be related to the stopper and / or tip, depending on which specific interface is tested. In a preferred embodiment, both interfaces, i.e., the inner surface / stopper and the mating surface / cap, must be tested and pass the test. If only one interface is to be tested, the other open end can be sealed by melting.
[0086] The container seal integrity for a specific ethanol-modified dye invasive test according to the system of the invention is at least 150 hours, at least 600 hours, or at least 1200 hours at -80°C. Preferably, the container seal integrity for a specific ethanol-modified dye invasive test according to the system of the invention is at least 1500 hours or at least 6000 hours at -80°C. Depending on the required shelf life of the pharmaceutical product, the container seal integrity for a specific ethanol-modified dye invasive test at -80°C does not necessarily have to be very high; for example, in some embodiments, it can be as long as 12000 hours, 10000 hours, or 8000 hours. The container seal integrity for a specific ethanol-modified dye invasive test may be related to the stopper and / or tip, depending on which specific interface is being tested. In a preferred embodiment, both interfaces, namely the inner surface / stopper and the mating surface / cap, must be tested and pass the test. If only one interface is to be tested, the other open end can be sealed by melting. Structural features of containers
[0087] In general, the present invention relates to a glass container for pharmaceutical compositions, comprising: a hollow cylinder having at least one open end, i.e., an open end adapted to fill, remove, or discharge container contents. The container may be configured to receive a stopper that is slidable relative to the hollow cylinder from the open end toward another end of the container (e.g., open end B). The stopper may be used to close open end A and / or discharge the contents of the hollow cylinder through open end B. In one embodiment, the container has at least two open ends. One open end is into which a stopper can be inserted, referred to in the present invention as "open end A". The other open end may be on the other side of the container, for example, the tip side if the container is a syringe.
[0088] In one embodiment, the glass container has an open end B, optionally disposed at the other end of the container opposite to the open end A, wherein the open end B is configured to be closed by a lid. The open end B may include a conical component or a component with a conical surface, so that the open end B can be closed with a lid that is adapted to the conical shape. The conical shape may be an inner cone or an outer cone. The invention is not limited to a conical open end; other geometries are also possible, as long as they are suitable for achieving a tight seal between the open end B and the corresponding lid. The surface of the open end B is referred to as the "fitting surface," which corresponds to the surface of the lid to form a tight seal. The open end B and / or its fitting surface may be configured to fit tightly against the surface of the lid. Optionally, the fitting surface is conical.
[0089] In one embodiment, at least a portion of the open end B or its mating surface is coated with the coating described in this invention. Optionally, the coating is provided on at least 25%, at least 35%, or at least 50% of the mating surface (area-by-area). In one embodiment, the coating is provided on at least 65%, at least 75%, at least 85%, or at least 95% of the mating surface. For example, the coating is provided on substantially the entire mating surface.
[0090] This invention is not particularly limited to container volume. In one embodiment, the volume enclosed by the hollow cylinder is at least 0.10 ml, at least 0.50 ml, or at least 1.00 ml. Optionally, the volume can be as high as 1000 ml, 200 ml, 100 ml, or 25 ml. In embodiments, the volume ranges from 0.1 ml to 1000 ml, 0.50 ml to 200 ml, or 1.00 ml to 25 ml. In one embodiment, the volume enclosed by the hollow cylinder is less than 10.0 ml.
[0091] The hollow cylinder has a cavity surrounded by a glass wall, wherein the wall thickness can be at least 0.50 mm, at least 0.80 mm, or at least 1.00 mm. Optionally, the glass wall thickness can be up to 10.0 mm, 8.0 mm, 5.0 mm, or 4.0 mm. In embodiments, the glass wall thickness is from 0.50 to 10.0 mm, from 0.80 mm to 8.0 mm, or from 1.00 mm to 4.00 mm. The term "wall thickness" as used herein describes the shortest distance between the inner and outer surfaces of the hollow cylinder.
[0092] As used in this paper, the term "outer diameter" refers to the maximum distance between two points on the outer surface of a hollow cylinder, where these two points are connected by a straight line that is perpendicular to and intersects the longitudinal axis of the hollow cylinder. The term "inner diameter" refers to the maximum distance between two points on the inner surface of a hollow cylinder, where these two points are connected by a straight line that is perpendicular to and intersects the longitudinal axis of the hollow cylinder.
[0093] The hollow cylinder of the container can have a substantially constant inner diameter, meaning that the total inner diameter variation is very small. "Total inner diameter variation" refers to the difference between the maximum and minimum inner diameter of the hollow cylinder. For example, the total inner diameter variation of the hollow cylinder can be less than 200 μm, less than 100 μm, less than 50 μm, or less than 25 μm. Optionally, the total inner diameter variation can be greater than 0.01 μm, greater than 0.10 μm, or greater than 1.0 μm.
[0094] In one embodiment, the ratio of the total variation in inner diameter of the coated portion along the inner surface of the hollow cylinder to the thickness of the coating is less than 500, less than 400, less than 250, or less than 150. In another embodiment, this ratio is at least 1.0, at least 5.0, or at least 10.0. For example, this ratio can range from 1.0 to 500, 5.0 to 250, or 10.0 to 150. Loosening force and gliding force
[0095] According to various aspects of the invention, the glass container may have a standardized sliding force of no more than 5.0 N.
[0096] Sliding force represents the force required to push the stopper through a hollow cylinder, while release force represents the force required to cause the stopper to initially move through a hollow cylinder. "Standardized sliding force" (GF) is the sliding force measured under standard conditions. Similarly, "standardized release force" (BLF) is the release force measured under standard conditions. These standard conditions include a standard stopper, namely a Datwyler FM257 / 2 stopper made of brominated butyl rubber with a Shore A hardness of 52 and a density of 1.355 g / cm³. 3 Available from Datwyler Pharma Packaging International NV, located at Industrieterrein Kolmen 1519, BE-3570 Alken, Belgium. BLF and GF can be obtained in a single measurement; the test for BLF and GF can be referred to as the "BLGF" test. The loosening force or sliding force mentioned in this invention, if related to a glass container, refers to the standardized loosening force or sliding force. If uncertain, any reference to BLF or GF in relation to the system refers to the specific BLF or GF of that system. "Specific" BLF or GF refers to the loosening force or sliding force measured in the system (i.e., including the system stopper, not the standard stopper). Otherwise, the measurement performed is the same as the standard test.
[0097] The standard BLGF test is performed at room temperature (20°C) using a general-purpose testing machine. For this purpose, a standard BLGF testing apparatus with a 50N test cup can be used. The sample is fixed vertically on a Model 106 2kN general-purpose testing machine manufactured by Havre GmbH (CH-6331, Hünenberg, Switzerland).
[0098] BLF is the force required to move the stopper from its original position, and GF is the force required to keep the stopper in motion after it has been released.
[0099] The container is filled with water for injection. After filling the sample, store it immediately, or test it immediately as needed. Test the sample without a needle.
[0100] Insert the sample into the holder and move the mold toward the stopper at a rate of 20 mm / min. Once a force of 0.25 N is measured, the machine switches to a testing speed of 100 mm / min and begins recording data. The experiment ends when the measured force exceeds 35 N, at which point the far end of the hollow cylinder (usually near the open end B) has been reached.
[0101] BLF is the maximum force measured within the first 4 mm of stopper movement. GF is the test interval measured from the point of movement 4 mm to the point of reaching the distal end of the tube in the first 10 mm. According to the invention, GF is the highest sliding force measured in this experiment.
[0102] The glass container according to the invention may have a standardized BLF of no more than 12.0 N. In some embodiments, the upper limit of the standardized BLF may be limited to 9.0 N, 8.0 N, 7.0 N, 6.0 N, 5.0 N, or even 4.0 N. The standardized BLF may be at least 0.1 N, at least 0.5 N, or at least 1.0 N to prevent any accidental movement of the stopper.
[0103] In this glass container, the ratio of normalized BLF to normalized GF, BLF / GF, is greater than 1.30. Optionally, the ratio of normalized BLF to normalized GF is characterized by BLF / GF being less than or equal to 3.0, particularly even after the glass container has been stored at -80°C for 150 hours. In embodiments, for the container according to the invention, the ratio BLF / GF is greater than 1.40, greater than 1.50, or even greater than 1.60. In some embodiments, after the container according to the invention has been stored at -80°C for 150 hours (“low-temperature stored container”), the ratio BLF / GF may be less than 2.5, less than 2.2, less than 2.0, or even less than 1.9. In particular, the relative difference (BLF / GF) between the low-temperature stored container and the unstored container is also considered. -80℃ -BLF / GF0) / BLF / GF-80℃ It may be less than 10%, preferably less than 5%. This means that the effect of the freeze-thaw cycle ratio BLF / GF is very low. On the other hand, as mentioned above, a high BLF / GF ratio means that it is quite difficult to loosen the stopper from its initial position, which may be due to the interaction between the coating and the stopper. A higher BLF is beneficial for keeping the stopper in its initial position even at low temperatures, i.e., when the pharmaceutical composition expands due to freezing.
[0104] The standardized GF of the glass container according to the present invention can be less than 7.5N, less than 6.5N, less than 5.5N, less than 4.5N, less than 3.5N, or even less than 2.5N. Optionally, the relative difference (BLF) between the cryogenically stored container and the unstored container on the standardized GF can be considered. -80℃ -BLF0) / BLF -80℃ Less than 25%, less than 20%, less than 15%, less than 10%, or even less than 5%. The relative difference in GF between containers stored at low temperatures and those not stored (GF). -80℃ -GF0) / GF -80℃ Less than 25%, less than 20%, less than 15%, less than 10%, or even less than 5%. Maintaining a fairly low GLF helps to fully drain the contents of the stoppered container after cryogenic storage.
[0105] Appropriate sliding and loosening forces facilitate the use of glass containers and systems according to the invention. Generally, a tight seal corresponds to higher loosening and / or sliding forces. Some glass containers according to the invention have very low standardized loosening and sliding forces. However, sufficiently high loosening forces may help prevent unwanted movement of the stopper during storage.
[0106] Optionally, the glass container according to the invention has a standardized sliding force of at least 0.5 N.
[0107] To prevent the stopper from shifting during low-temperature storage and thus ensure a tight seal, the glass container according to the invention may have a standardized loosening force that exceeds the container's standardized sliding force by at least 30%, at least 60%, at least 100%, or at least 200%.
[0108] In one embodiment, the system according to the invention has a specific release force that is at least 600% greater than the sliding force, and the specific release force is at least 4.0 or at least 4.9.
[0109] In one embodiment, the present invention relates to the glass container or system described herein, which includes a pharmaceutical composition. The pharmaceutical composition may include more than 60 wt% water. Optionally, the pharmaceutical composition includes a protein or nucleic acid therapeutic agent. system
[0110] In some aspects, the present invention relates to a system comprising a glass container according to the invention and optionally a stopper and / or a lid. The stopper may close an open end A, and / or the lid may close an open end B.
[0111] In one embodiment, the system includes a glass container and a stopper according to various aspects of the invention, wherein the system has container seal integrity for at least 150 hours of a specific ethanol-modified dye intrusion test at -80°C.
[0112] The container seal integrity for this specific ethanol-modified dye invasive test may be related to the stopper and / or tip. "Related to the stopper" means testing the seal integrity formed by the stopper located within a hollow cylinder, i.e., the sealed open end A. "Related to the tip" means testing the seal integrity formed by the cap, which opens to the tip side, i.e., the sealed open end B. Unlike standard container seal integrity tests that rely on standard stoppers, plungers, and / or caps, the container seal integrity for this specific ethanol-modified dye invasive test is measured using the stopper and / or cap, which are part of the system being tested.
[0113] Optionally, the system may have container seal integrity for at least 300 hours, at least 600 hours, or at least 1200 hours for a specific ethanol-modified dye invasive test at -80°C. plug
[0114] The system according to the invention may include a plug.
[0115] The stopper may include a body having at least one annular protrusion and a circumferential surface. A “circumferential surface” refers to the surface of the stopper facing the inner surface of the hollow cylinder when the stopper is placed within the cylinder, for example, inserted through the open end A. This circumferential surface includes the surface of any annular protrusion. If the stopper is coated, the coated surface facing the inner surface of the hollow cylinder is part of or constitutes the circumferential surface. A “contact surface” refers to the portion of the circumferential surface that contacts the inner surface of the hollow cylinder when the stopper is inserted (e.g., at 20°C). In this invention, it may be advantageous if the stopper is uncoated. Studies have found that uncoated stoppers can form a tighter seal at low temperatures compared to coated stoppers. In one embodiment, the stopper does not include a fluoropolymer coating.
[0116] An "annular protrusion" is a portion of the stopper with a diameter greater than the average diameter measured perpendicular to the longitudinal axis of the hollow cylinder. The annular protrusion can contact the inner surface of the hollow cylinder to seal the joint between the stopper and the hollow cylinder. Any portion of the stopper not considered an "annular protrusion" if its diameter is greater than the average diameter but it does not contact the inner surface of the hollow cylinder for at least 80%, 90%, 99.9%, or 100% of the time during distal movement of the stopper. The annular protrusion helps hold the stopper in its intended position within the hollow cylinder, thereby stabilizing its orientation in the proximal-distal direction, which affects the container's BLF and GF values. Furthermore, the annular protrusion seals the joint between the stopper and the inner surface of the hollow cylinder. In one embodiment, the stopper may have two, three, or four annular protrusions. Optionally, the stopper may have exactly three annular protrusions.
[0117] Optionally, the stopper may have one or more trailing ribs. A "trailing rib" is a part of the stopper whose diameter, measured along the longitudinal axis perpendicular to the hollow cylinder, is larger than the average diameter. However, the diameter of the trailing rib is smaller than the diameter of the annular protrusion; therefore, as the stopper moves in the proximal-distal direction, the trailing rib is highly unlikely to contact the inner surface of the hollow cylinder. Thus, the trailing rib can stabilize the orientation of the stopper within the hollow cylinder without effectively sealing the joint between the stopper and the inner surface.
[0118] The stopper may be coated with a coating, which may be a polymer. In one embodiment, the coating comprises a resin, such as a fluorinated polymer, selected from the group consisting of: polytetrafluoroethylene (PTFE), expanded polytetrafluoroethylene (ePTFE), tetrafluoroethylene (TFE), tetrafluoroethylene-perfluoroethylene copolymer, tetrafluoroethylene-hexafluoropropylene copolymer, tetrafluoroethylene-ethylene copolymer, trichlorotrifluoroethylene, polyvinylidene fluoride, polyvinyl fluoride, perfluoropropyl vinyl ether, perfluoroalkoxy polymers, and copolymers, mixtures, and combinations thereof. The coating may also be formed from a layer of polyethylene, polypropylene, parylene, polylactic acid, and copolymers, mixtures, and combinations thereof. Preferably, the coating is a polytetrafluoroethylene coating. The above coating can reduce the coefficient of friction between the circumferential surface of the stopper and the inner surface of the hollow cylinder. In an embodiment, at least the portion of the circumferential surface of the stopper in contact with the inner surface of the hollow cylinder will be coated.
[0119] The stopper may be an elastomer with a yield stress of at least 10 MPa as measured according to ISO 527-2:2012(E), and / or a low coefficient of sliding friction against steel of less than 0.23 as measured according to DIN EN ISO 8295 / 2004-10. The stopper may be made of thermoplastic elastomers and / or rubbers such as natural or synthetic rubbers. Suitable rubber materials may be selected from the group consisting of: butyl rubber, halogenated butyl rubber, acrylonitrile-butadiene rubber, isoprene rubber, chloroprene rubber, butadiene rubber, styrene-butadiene rubber, ethylene-propylene rubber, isoprene-isobutylene rubber, nitrile rubber, and combinations and mixtures thereof. In one embodiment, the stopper is made of brominated butyl rubber. In particular, the body of the stopper may be made of the rubbers and / or thermoplastic elastomers listed above.
[0120] The main body can be coated with the aforementioned resin. The thickness of the stopper coating can be less than 1 mm, particularly 0.5 μm to 200 μm, particularly 10 μm to 125 μm, or 30 μm to 100 μm. It has been proven that the above thicknesses are easy to apply and sufficient to achieve the desired effect against friction.
[0121] The water contact angle of the circumferential surface of the stopper can be at least 100°, or even at least 110°. The circumferential surface of the stopper can be superhydrophobic. Using a superhydrophobic stopper in the container of the present invention helps to obtain a favorable BLGF value because of its low coefficient of sliding friction and low adhesion tendency.

[0197] Optionally, the crosslinkable polysiloxane structural unit, the low-viscosity non-crosslinkable polysiloxane structural unit, and / or the high-viscosity non-crosslinkable polysiloxane structural unit may include a dialkylsiloxane monomer unit, particularly a dimethylsiloxane monomer unit. The crosslinkable polysiloxane structural unit may be crosslinked via one or more polymerizable end groups.
[0198] The coating composition can be applied using conventional methods known in the art. In one embodiment, the method includes coating at least a portion of a glass container with the coating composition, such as wiping, dipping, spraying (e.g., ultrasonic spraying), or curtain coating. In a preferred embodiment, the coating composition can be applied using a wiping process.
[0199] The coating composition can be applied to achieve the desired coating thickness. The coating thickness can be greater than 250 nm, greater than 300 nm, greater than 400 nm, greater than 450 nm, or greater than 500 nm. Optionally, the coating thickness can be up to 1500 nm, 1250 nm, or 1000 nm. Appropriate coating thickness contributes to achieving a tight seal at low temperatures. In embodiments, the coating thickness can be from 250 nm to 1500 nm, from 300 nm to 1250 nm, or from 400 nm to 1000 nm. Optionally, the above-mentioned indices for coating thickness mean that at least 90%, at least 95%, or at least 99% of the coating area has a coating thickness within the indicated range. In a preferred embodiment, the coating thickness is greater than 400 nm, particularly at least 450 nm or at least 500 nm. Exemplary preferred ranges for coating thickness are greater than 400 nm to 1500 nm, or 450 nm to 1250 nm, or 500 nm to 1000 nm.
[0200] To achieve a suitable sealing effect, it is generally sufficient to apply the coating composition to the areas requiring a tight seal, namely the contact area between the inner surface and the stopper, and / or the contact area between the mating surface and the cap (the sealing area). The coating composition may be applied (area-by-area) to at least 25% or at least 50% of the inner surface of the hollow cylinder. However, this coating may also have a beneficial effect on the sliding properties of the stopper on the inner surface of the hollow cylinder. Therefore, in some embodiments, the coating composition is applied (area-by-area) to at least 65% or at least 85% of the inner surface of the hollow cylinder. Optionally, the coating composition is applied to at least 90% or substantially the entire inner surface of the hollow cylinder. In some embodiments, the coating composition is applied (area-by-area) to at least 65% or at least 85% of the mating surface of the glass container. Optionally, the coating composition is applied to at least 90% or substantially the entire mating surface.
[0201] The term "curing temperature" as used here refers to the effective temperature at which the coating can be cured. The curing temperature is not the nominal temperature in the oven, which may be higher than the effective temperature of the coating during curing. Curing may include polymerizable polymerizable groups, such as polymerizable end groups. The coating can be cured at curing temperatures below 150°C, below 125°C, or below 110°C. Too high a curing temperature may result in low elasticity of the coating. On the other hand, too low a curing temperature may not be sufficient to achieve good sealing performance. Therefore, in embodiments, the curing temperature may be above 50°C, above 60°C, or above 70°C. It is important to note that the curing temperature is the effective temperature of the coating composition. It should not be confused with the nominal oven temperature. The oven temperature may be much higher than the curing temperature because there may not be enough time during the curing period for the entire oven to equilibrate at the nominal temperature. Optionally, the curing temperature of the coating may be from 50°C to less than 150°C, from 60°C to less than 125°C, or from 70°C to less than 110°C. Preferably, the curing temperature range is from 50°C to less than 110°C. In a preferred embodiment, curing does not involve the application of plasma.
[0202] The curing temperature can be maintained for a sufficient time to achieve the desired degree of curing. Optionally, the curing temperature can be maintained for at least 10 seconds, at least 30 seconds, at least 45 seconds, or at least 60 seconds. In embodiments, the curing temperature is maintained for up to 3000 seconds, up to 300 seconds, or up to 180 seconds.
[0203] The present invention also relates to the use of the coating composition as described above for preparing a coating on the surface of a glass container, wherein the coated glass container is subsequently stored for at least 150 hours in a low temperature range below -60°C, particularly at a low temperature of about -80°C. Optionally, the coated glass container is stored for at least 600 hours or at least 1200 hours. In one embodiment, the glass container is stored for at least 1500 hours or at least 6000 hours. Depending on the required shelf life of the pharmaceutical product, the glass container may be stored for up to 12000 hours, up to 10000 hours, or up to 8000 hours. Preferably, the glass container is the glass container described in this invention.

[0219] In one specific embodiment, the system according to the invention comprises: a glass container, particularly a glass container according to one of the specific embodiments; and a stopper and / or a lid, wherein the system has container seal integrity tested for at least 150 hours at -80°C using a specific ethanol-modified dye intrusion test.
[0220] In one specific embodiment, the system according to the invention comprises: a glass container, particularly a glass container according to one of the specific embodiments; and a stopper, wherein the ratio of the difference (I) between the average linear coefficient of thermal expansion of the material of the stopper and the material of the glass container to the thickness (II) of the coating is less than 0.5 ppm / nm, wherein the system has container seal integrity under a specific ethanol-modified dye intrusion test at -80°C for at least 150 hours. Container seal integrity in ethanol-modified dye invasive test
[0221] Now refer to Figure 2 This paper describes the container seal integrity test for ethanol-modified dye intrusion.
[0222] Figure 2 An apparatus 200 for determining the seal integrity of a container at different stages of ethanol-modified dye intrusion is schematically shown. The apparatus 200 includes an immersion apparatus 270 and a container 201 used in conjunction with the immersion apparatus 270.
[0223] Container 201 is a glass container, such as the glass container according to the invention, comprising a hollow cylinder 210 with two openings, namely, an opening end A 212-1 and an opening end B 212-2 disposed on different sides of the glass container. Each opening 212-1, 212-2 is sealed by a sealing device plug 230-1 or a lid 230-2. The container volume 205 of the glass container 201 is defined by a portion of the inner wall of the container body 210 and the inner surface of each sealing device 230-1, 230-2.
[0224] For standard ethanol-modified dye intrusion container seal integrity tests, the stopper is a Datwyler FM257, and the cap is a West W7025 Luer lock SRC rigid cap (as described in EP3569272A1). For specific ethanol-modified dye intrusion container seal integrity tests, the stopper is the stopper of the system under test, and the cap (if any) is the cap of the system under test.
[0225] In the example shown, glass container 201 is a medical syringe or medicine cartridge. The same test can be performed on other types of glass containers. The proximal open end A 212-1 of the container is sealed by a stopper-like closure device 230-1. The distal open end B 212-2 of the container is located at the top of container 201 and is sealed by a cap-like closure device 230-2.
[0226] To achieve this test objective, container volume 205 is filled with air at a pressure of 1 atm and sealed using a suitable sealing device. Immersion equipment 270 includes immersion device 272. Immersion device 272 is provided with a reservoir containing ambient liquid 274. Immersion device 272 also includes conditioning facilities for adjusting and maintaining the temperature of ambient liquid 274 according to the test protocol.
[0227] At the start of the test, container volume 205 is completely filled with air. Additionally, the temperature of both container 201 and the gas within container volume 205 can be adjusted to 20°C. The ambient liquid 274 is adjusted to -80°C; ambient liquid 274 is ethanol containing a fluorescent dye (fluorescein disodium, 1 g / L).
[0228] like Figure 2 As shown in b), in the next step, container 201 can be completely immersed in ambient liquid 274. When immersed in ambient liquid 274, the temperature of container 201 will gradually approach at least -80°C. The absolute heat capacity of container 201 is very small relative to the absolute heat capacity of ambient liquid 274. Thus, the temperature change of ambient liquid 274 is minimal, given that container 201 is not immersed in it. When the temperature of container 201 decreases due to immersion in ambient liquid 274, the temperature of the gas in container volume 205 will decrease accordingly. Therefore, the gas in container volume 205 will contract, and the gas pressure in container volume 205 will drop below ambient pressure.
[0229] The container 201 is kept in the ambient liquid 274 for at least a predetermined period of time, which begins when the container is fully immersed in the ambient liquid 274 and ends when the container 201 is removed from the ambient liquid 274 and equilibrates with room temperature (preferably 20°C).
[0230] Figure 2c) This schematically illustrates two possible outcomes after removing container 201 from ambient liquid 274. In example i), the amount of ambient liquid L can be detected within container volume 205. Specifically, the amount L of ambient liquid 274 has exceeded the boundary of the tip region in container 201. This indicates that there is a leak in the tip region of container 201 under the conditions of the previous stages a) and b). In example ii), no ambient liquid 274 is detected in container 201. This indicates that container 201 is well-sealed under the conditions of the previous stages a) and b).
[0231] If no ambient liquid is detected inside the container, including between the annular protrusions of the stopper or between the closure and the coated surface, the container is considered to have passed the test. Example Exemplary container
[0232] Now refer to the attached diagram, Figure 1 A glass container 1 according to an exemplary embodiment is shown, which is a syringe 3 for injecting pharmaceuticals or cosmetics. The syringe 3 is made of glass and includes a glass wall 5 surrounding a cavity. The container includes a hollow cylinder 7 and a fitting surface 18 on which an injection needle or cap can be placed, for example. A stopper 12 is inserted into the cylindrical portion and can slide axially by pressure from a push rod 13. The cylindrical portion is provided with an operable flange 15 at the inlet end of the stopper 12, i.e., the open end A.
[0233] The inner surface of the glass container 1 is provided with a coating 10, specifically referring to the inner surface of the hollow cylinder 7. In this example, the coating 10 covers an area of the inner surface of the hollow cylinder 7, on which the stopper 12 can slide when the syringe is emptied or used for removal. Coating composition
[0234] Multiple sets of glass syringes (Schott SyriQ 1.0ml long, Fiolux Clear) were coated with a coating composition. The coating composition used is as follows.
[0235] The glass syringe is coated using a spray method. The coating is then cured at high temperature in an oven. During the curing process, the diluent evaporates, and the crosslinkable polysiloxane forms a network during the hydrosilylation reaction. Coating thickness
[0236] Coatings of varying thicknesses were applied to glass syringes and cured at 70°C for 60 seconds. The coatings were applied to the inner surface of the syringe barrel and the mating surface of the syringe tip. Then, both open ends were sealed. Open end A was sealed using a Datwyler FM257 stopper, and open end B was sealed using a West W7025 tip cap. As described above, the samples were tested in a container seal integrity test for ethanol-modified dye intrusion. Samples F and G used the latest silicone oil (DuPont). D360), with viscosities of 1000 cSt and 12500 cSt respectively.

[0238] Differential scanning calorimetry (DSC) was performed on the cured coating sample, and the cured coating was scraped off the glass (according to DIN 51007:2019). The experiment was conducted on a DSC Q2000 (TA instrument) with a temperature change rate of 10 °C / min and a range of -120 °C to -60 °C. The experiment could be repeated twice to confirm the measurement results.
