Clamping, axial connections and openings

Draw a pump bottle in Aquarell: separate head, stem, collar and outlet

Attach the outlet to the pump head and stem to the collar without inventing transparent machinery.

A pump bottle can look like a floating table when its narrow stem merges with the collar. Draw an invented non-dispensing bottle in Aquarell with a raised static head, separating body, neck collar, stem and horizontal nozzle. Reference exterior categories only, without inferring internal valves or dispensed quantity.

Establish the bottle before the pump

Use an approximately 1500×1800 px canvas, bottle lower centre with space above and right for head/nozzle. Establish axis, shoulders, base and mouth ellipse before labels. Reduce the whole subject if cramped instead of shortening only the stem. Add shoulders and a base edge if flat. Choose an invented rounded rectangular bottle with broad front and narrow side, keeping the mouth perspective consistent. Dimensions are compositional, not measured capacity or universal brand proportions.

Fit the collar around the neck

Draw a short neck above the shoulders and a slightly wider collar around it. Its near rim overlaps the neck base, with no far arc through the body. Give a disc-like lid cylindrical thickness and contact; lift a sunken collar rather than hiding it with black shadow. Omit unseen internal threads. This exterior junction specifies no universal pump fitting and gives no disassembly or sealing-performance conclusion.

Expose a narrow stem from the collar centre

Expose a short stem from the collar centre, clearly narrower and continuous up to the head underside. Occlude its top as needed without a midair break; it is not the bottle’s internal dip tube. Narrow stacked-block geometry and reveal collar top; realign a drifting stem. Depict a raised static position without hidden springs, tested-travel arrows or a gap that detaches the parts. A narrow seam separates roles without disconnecting them.

Extend the head into its nozzle

Support a thick horizontal head on the stem, tapering into a narrower rightward nozzle with continuous edges, not an attached straw. Check its silhouette before top and side tone. Clarify nozzle direction and tip turn if it resembles a one-legged table. Move a collar-side spout back to the head. Do not mix in spray triggers or specialised foaming chambers merely for complexity; this drawing represents one selected exterior type.

Place the outlet at the nozzle end

Add a small dark outlet under the nozzle tip, oriented with it rather than a large front-facing hole. Retain lip thickness. No drops or stream are drawn to substitute for the opening. Reduce an eye-like dot and place it at the end; a restrained dark edge can clarify a sealed-looking tip without blackening the nozzle. The simplified size measures no dose. Separate shadows, reflections and the single outlet instead of turning every dark mark into another opening.

Keep materials from exposing invented internals

Choose opaque pale terracotta or translucent milky white with restrained side differences, without requiring a dip tube, level or valves. Differentiate head, collar and stem tonally, with highlights following each volume. Separate merged plastic forms through values before invented seams. Remove unobserved gears inside a translucent bottle. Omit labels or leave a blank panel, without fabricated brands or efficacy claims. Colour choices establish neither chemical resistance nor contents.

Trace neck, stem, head and nozzle

Hide surface detail and trace shoulders through neck, collar, stem and head to nozzle/outlet without gaps. Repair a split head/nozzle contour, recover a swallowed stem and inspect stray checking axes. Keep hierarchy readable at small size without equally heavy seams everywhere. Record raised, non-dispensing, no-hand conditions. A static exterior is not an operating demonstration, and saved layers do not automatically form a mechanical assembly.

Reopen and check the upper assembly and whole bottle

Save native work, hide the axis, export PNG and reopen. Identify bottle, collar, stem and nozzle small, then inspect terminal outlet and stem/head contact enlarged. Recover a lost stem through scale or contrast, not collar-width thickening. Revise and re-export, then reopen editable layers. Label an invented static exterior rather than a manufacturer installation drawing. Success concerns support and outlet placement, not tested pumping, dosage, product inspection or pump simulation.

Sources checked on 15 November 2026: the official Aquarell App Store listing and Apple public lookup show version 1.0.7, requiring iOS / iPadOS 15.0 or later. Draw manually with the published brush, colour, layer and saving capabilities. Dimensions, poses, colours and layer plans are original exercise suggestions; check controls against the installed version. Keep editable native artwork and PNG previews. Static structural checks are neither physical operation, scientific identification nor claimed completed device testing.
