Bottle Cap Collection Display Aluminum Bottle With Screw Cap

1. Product Overview

2. Product Specifications & Parameters (Collector-Focused Details)

3. Product Features (Solves Collector Pain Points)

3.1 “I Want to See My Caps, Not Just Store Them” – Clear UV-Protective Window

• The HDPE window isn’t thin plastic (which scratches or yellows). It’s 2mm thick, like a small tablet screen—we rubbed it with a cap opener 50 times (a common collector tool) and it still looked clear.
• UV protection matters: A collector in Florida told us his vintage beer caps faded in 6 months in a sunny window. Our window blocks 90% of UV rays—we tested caps in the bottle for 12 months, and they looked as bright as day one.
• The window’s vertical shape lets you line up your favorite caps (e.g., a full set of sports team caps) so everyone can see them—no more digging through a jar to find the one you want.

3.2 “My Caps Get Scratched or Dusty” – Tight Seal & Soft Interior

• The screw cap has a silicone gasket that presses against the bottle’s rim—we filled the bottle with caps, closed it, and shook it for 5 minutes (simulating moving shelves). No dust got in, and no caps rubbed together enough to scratch.
• The aluminum body’s interior is smooth—we sanded every inch by hand (no machine can get rid of tiny burrs like a person can). A collector with vintage soda caps said, “I used to avoid metal jars because they scratched my paper labels—this one doesn’t.”

3.3 “I Collect Different Size Caps” – Optional Adjustable Divider

• Not all caps are 28mm—some beer caps are 38mm, some vintage soda caps are 30mm. The optional divider has 3 sections you can move (slide them left/right) to fit different sizes.
• We tested it with a mix: 28mm soda caps on one side, 38mm beer caps on the other—no overlapping, no squeezing. A collector in Texas said, “This divider let me stop using two separate jars—I can keep my whole collection in one place.”

3.4 “I Want It to Look Nice in My Home” – Sleek Brushed Aluminum

• The brushed finish doesn’t show fingerprints (we tested with oily hands—wipe it with a cloth, and it’s clean). It matches modern shelves, rustic desks, even man caves—no “cheap storage jar” look.
• We offer custom engraving (e.g., “John’s Cap Collection” or “Est. 2023”) on the side—done by hand with a laser, so it’s permanent (no peeling stickers). A customer bought 20 for a groomsmen gift—they all said it was “the most unique gift they’d ever gotten.”

4. Production Process Flow (Human-Centric Quality)

4.1 Step 1: Aluminum Prep (No Thin, Flimsy Metal)

• We buy 3003-series aluminum sheets from a local supplier (we visit their warehouse monthly to check quality—no recycled scrap that has hidden cracks).
• Hand Cutting: A technician cuts the aluminum into circles (for the body) with a shear—they measure each circle twice (80mm diameter) to avoid “off-size” pieces. If a circle is even 1mm too small, it gets recycled.
• Body Shaping: We use a hydraulic press to stretch the aluminum into a cylinder—slowly (2 minutes per body, not 10 seconds). Slow stretching makes the aluminum thick and even (no thin spots that dent easily). A senior tech checks the wall thickness with a caliper—must be 1mm, no exceptions.

4.2 Step 2: Window Installation (No Leaks, No Loose Glass)

• Window Cutting: The HDPE window is cut by hand (not a machine) to 50mm × 150mm—we sand the edges so they don’t catch on caps when you’re adding them.
• Glue Application: We use food-grade epoxy (safe, no smell) to attach the window to the aluminum body. A tech applies the glue in a thin, even line (too much glue oozes inside and ruins the look). They hold the window in place for 2 minutes by hand (no clamps—clamps leave marks) to make sure it sticks.
• Curing: We let the glue dry for 24 hours (not 4 hours like cheap suppliers). After curing, a tech tries to pry the window with a flathead screwdriver—if it moves, we redo it.

4.3 Step 3: Screw Cap & Gasket Assembly (Tight Seal Every Time)

• Cap Machining: The aluminum screw cap is turned on a lathe—our machinist adjusts the thread (53mm) by hand to make sure it twists smoothly on the bottle. We test 10 caps per batch on a sample bottle—no “stuck” or “loose” caps.
• Gasket Insertion: A worker hand-presses the silicone gasket into the cap’s groove (automated inserters sometimes misalign gaskets, which causes leaks). They check each cap by closing it on a bottle and turning it upside down—no gasket slippage = pass.

4.4 Step 4: Final Check (Collector-Level Inspection)

• Visual Check: A tech looks for scratches on the aluminum, bubbles in the window glue, or uneven threads—even a tiny scratch means the bottle is set aside (we fix it by hand or recycle it).
• Function Test: We fill the bottle with 50 28mm caps, close the screw cap, and shake it for 2 minutes. Then we open it—caps should be undamaged, no dust inside, and the window should still be clear.
• Personal Touch: Every bottle gets a small hand-stamped batch number (e.g., AC240705) on the base—so if you ever have a question, we can trace exactly when and how it was made.

5. After-Sales Assurance (We Stand Behind Your Collection)

5.1 Warranty: 1 Year, No Fine Print

• What’s Covered:
  • Aluminum body dents (if it dents from normal use—e.g., accidentally knocking it off a desk, not dropping it from a roof).
  • Screw cap threads wearing out (can’t twist closed).
  • Window glue failing (window comes loose).
• How to Claim: Email us a photo of the issue (no need to ship the bottle first) and your order number. We’ll send a replacement within 5 days—free shipping, even international.
• A customer in Canada had a window come loose after 8 months—we sent a new bottle, no questions. They said, “I didn’t expect that level of service—most companies make you jump through hoops.”

5.2 Returns: 30 Days, No Hassle

• If the bottle is too big/small for your collection, or you just don’t like it, send it back within 30 days. We’ll refund 100% of your money, including shipping (we even send you a pre-paid label).
• We ask for one thing: just make sure the bottle is unused (no caps inside, no scratches). A customer in New York bought it for their kid’s collection but realized it was too big—we refunded them the same day we got the bottle back.

5.3 Custom Order Support

• If you ordered a custom color or engraved bottle and it’s wrong (e.g., misspelled name), we’ll remake it for free—no extra cost. We send a proof of the engraving/color before production, but if we still mess up, it’s on us.
• A wedding party ordered 15 engraved bottles with the groom’s last name—we misspelled it “Smith” instead of “Smyth.” We remade all 15 and shipped them in 3 days, just in time for the wedding.

5.4 Collector Tips & Support

• We send a free “Cap Collection Guide” with every bottle—tips on cleaning caps, organizing them in the bottle, and even where to find rare caps.
• If you have questions (e.g., “Will 38mm caps fit without the divider?”), email us anytime. We have a team member who’s a cap collector themselves—they’ll give you real advice, not scripted answers.
