Every dimension of the LISSON glass packaging range has been conceived through the lens of human-centered design, ensuring that each capacity delivers an optimal user experience tailored to its intended application.
Proportional Intelligence:
The 30ml bottle adopts a slender, elongated profile that fits comfortably between thumb and forefinger—ideal for precision application of high-value serums and treatment oils where dosage control is critical. Its compact footprint makes it the perfect candidate for travel retail, subscription boxes, and luxury sample programs.
The 50g jar format features a low, wide-mouth design that facilitates easy product access for thicker formulations such as moisturizing creams, balms, and masks. The broad opening allows for hygienic spatula or finger-dipping, while the generous surface area enables full hand-pump actuation for the AS+PP closure.
The 100ml bottle strikes the perfect balance between presence and practicality—tall enough to command shelf attention, yet compact enough to fit comfortably in the hand. This volume has become the industry standard for daily-use facial moisturizers, essences, and treatment lotions.
The 120ml bottle offers a slightly more generous silhouette, signaling value and abundance. Ideal for body lotions, hair treatments, and high-consumption staples, this size reassures the consumer of lasting supply while maintaining an elegant, non-bulky aesthetic.
Ergonomic Considerations:
The AS+PP cap features gently rounded edges and subtle vertical ribbing around the circumference—a design detail that provides confident grip even with wet or product-slicked hands. The cap's height-to-diameter ratio has been optimized to ensure effortless torque application, eliminating the frustration of stuck or cross-threaded closures.
The pump actuator incorporates a subtle concave depression that naturally guides the user's fingertip into the optimal actuation position. This ergonomic refinement reduces finger fatigue during multiple pumps and ensures consistent force application, resulting in uniform dosing across every use.
Visual Cohesion:
When displayed together, the four capacities create a harmonious family—a visual gradient of sizes that suggests a complete, thoughtfully curated product line. The transparent glass and crystal-clear AS cap create a consistent visual language across all SKUs, allowing your brand's color identity to shine through the packaging itself. The unified neck finish across volumes further reinforces this sense of family, enabling interchangeable components and simplifying your production line.
User Interface Details:
-
Meniscus Visibility: The transparent glass body provides an unobstructed view of remaining product levels, eliminating the unpleasant surprise of unexpected depletion.
-
Low Center of Gravity: The bottle proportions ensure stability on vanity surfaces, reducing the risk of tipping during pumping.
-
Dip Tube Precision: Cut to length with micron-level accuracy, the suction tube reaches within 1.5mm of the bottle base, ensuring near-complete evacuation and minimizing consumer frustration over wasted product.
Glass Bottle Manufacturing:
The glass bottles are produced through either the blow-blow forming process (for narrow-neck designs) or the press-blow process (for wide-mouth jar formats), depending on the specific capacity and neck configuration. Each bottle undergoes:
-
Hot-End Forming: Molten glass at temperatures exceeding 1,200°C is precisely shaped using computer-controlled molds, achieving wall thickness consistency within ±0.15mm tolerance—minimizing weak points that could compromise structural integrity.
-
Annealing Process: Post-forming, bottles pass through a controlled cooling lehr where internal stresses are systematically relieved over a period of 60-90 minutes. This critical step prevents spontaneous cracking during temperature fluctuations.
-
Cold-End Surface Treatment: A proprietary fluorination or sulfur dioxide coating is applied to the exterior surface, increasing scratch resistance and enhancing surface hardness. This treatment also improves ink adhesion for subsequent decoration processes.
-
Quality Inspection: Every production batch undergoes 100% visual inspection, supplemented by automated dimensional measurement and pressure testing. Statistical process control (SPC) monitors critical parameters including neck finish concentricity, verticality, and wall thickness distribution.
PP Pump Engineering:
The polypropylene pump mechanism represents the pinnacle of precision injection molding:
-
Virgin Food-Grade PP: Sourced from ISO-certified suppliers, with a melt flow index (MFI) carefully selected to balance flowability during molding with mechanical strength in the finished component.
-
Internal Ball-Valve Mechanism: The check valve and piston assembly are manufactured with sealing tolerances of ±0.02mm—ensuring leak-proof performance and reliable prime retention. The ball valve prevents backflow, guaranteeing that the pump remains primed even after extended periods of disuse.
-
Spring Specification: The stainless steel spring is engineered to deliver consistent actuation force across thousands of cycles, tested to >10,000 actuations without significant loss of tension.
-
Output Calibration: Each pump is calibrated to deliver 0.2ml ±5% per stroke, ensuring consistent dosing for precise application and predictable product consumption.
-
Chemical Resistance Testing: The PP material undergoes rigorous compatibility testing against a wide range of formulation types: oils, silicones, surfactants, acidic actives (pH 3-5), and essential oils—with zero evidence of swelling, leaching, or degradation.
AS+PP Cap Manufacturing:
The dual-material closure is produced through a sophisticated two-shot injection molding process:
-
First Shot (AS Outer Shell): The transparent Acrylonitrile Styrene component is molded first, achieving exceptional optical clarity with a light transmission rate exceeding 90%. The AS material is formulated with UV stabilizers to prevent yellowing over time.
-
Second Shot (PP Inner Liner): The polypropylene sealing component is injection-molded directly onto the AS substrate, creating a chemical and mechanical bond between the two materials without the use of adhesives—eliminating the risk of delamination.
-
Thread Engineering: The cap's thread design is precision-machined to mate perfectly with the glass neck finish, requiring only 270° of rotation for complete closure. This prevents overtightening while ensuring a leak-proof seal.
-
Torque Retention Testing: Each cap lot is tested for thread engagement torque (opening and closing) over a minimum of 20 full cycles, ensuring consistent performance throughout the product's usable life.
