Use baby shampoo clone? Pump lotion? They both use the same bottle neck threads. Use the interchangeability to improve your product economy for dispensing amounts and product buys.
If you use baby shampoo, maybe you opt for a superstore brand rather than the often more expensive famous-name version, The teardrop-shaped item commonly weighs 13.6 ounces, and comes with the screw-on cap being a press-top. You dispense by pressing the top at one edge, then squeeze fluid out. As the bottle gets emptier over time, it requires tipping.
Tipping Point?
Eventually, the tipping requires shaking the bottle upside down for each use. Tipping, inverting, shaking becomes tedious and a necessary subtask of using the shampoo. When you perceive the tedium, you can ease it some by finding and cutting the bottom of a larger container and inverting the baby shampoo bottle in it, thus letting gravity help drain it.
An even more effective method is repurposing a pump that uses the same bottle neck threading standard of 24-410 as the baby shampoo. More on that later.
Dispensing Too Much, Too Often?
Consider how much shampoo you dispense for each pour. Or how many pours it takes before you need to buy a new bottle. Or that, over time and times of bottle inverting, you've spent a lot of time waiting for shampoo to reach the opening. Oh, yeah! It's time for another shampoo buy.
Tightening the Baby Shampoo Use
Here's a way to save time and also delay replenishing bottles of baby shampoo. In short, pump-press the shampoo out while the bottle is upright.
The 24-410 Neck Threading Connection, Testing for Cap Fit, etc.
If you use a pump bottle of lotion, it might use the same bottle neck threading standard (24-410) as the 13.6-oz baby shampoo. (More details about the standard farther down.)
Do the cap widths of the pump lotion and baby shampoo look the same size or nearly so? If so, uncap both bottles. How many turns do the bottle necks have? The baby shampoo has 1 1/2 threads. If the lotion bottle has 1 1/2 threads, you're in luck. Try to screw the baby shampoo cap onto the lotion bottle. If it fits, you have the cap match.
Regarding 24-410, the first number refers to neck diameter in mm. The second number refers to the bottle's neck finish, info about neck height and number of continuous threads. "Guide to Bottle Neck Finishes, Thread Sizes, & Dimensions" provides loads of info and illustrations.
My superstore 13.6 oz baby shampoo (press-top cap) and 24-oz Lubriderm (pump cap) both use the 24-410 threading standard. Thus, the dispensers are interchangeable. BTW, best to have at least one spare baby shampoo press-top cap. Also, you might need to use up a good amount of the lotion to reuse/repurpose the pump.)
Overview of Video Content for Use of Caps for Baby Shampoo and Lotion Pump
- Initial use of a baby shampoo cap to extract lotion. When the lotion bottle runs low, replace the pump with a baby shampoo press-fit cap. Set the lotion bottle upside down in a larger cut-bottle bottom so that gravity helps pull the lotion down for dispensing. (I've used a large mouthwash bottle.)
- Prepping of the removed pump dispenser. Set aside the straw (measured as 6 mm) for later diameter matching. Wash the pump in soapy water to remove lotion remnant, pumping several times till the water runs clear. Towel dry, then let air-dry for a few days.
- Finding suitable replacement pump straw for diameter. If you have a stash of eatery beverage straws, look for one that matches the diameter of the set-aside lotion straw. Press the straw into the pump straw holder. Test for snugness (friction fit). If diameter to big or small, pump hack won't work effectively.
- Trimming the suitable replacement pump straw. Eyeball the length of straw needed for the baby shampoo bottle. Better too long and needing trimming than too short.
- Inserting and screwing down the pump-and-straw unit. Ensure
the straw does not hit bottom. If it looks like it might, remove the
pump-and-straw unit, and trim some more. (The eventual length was 4.2".)
Note: Google AI advises trimming the straw in a sharp "V" shape.
When you cut the drinking straw to length, cut the bottom at a sharp angle (like a "V") rather than flat. If a straw is cut perfectly flat and touches the absolute bottom of the bottle, the suction can create a vacuum and seal itself shut against the plastic floor, preventing the shampoo from drawing up.
- Testing amount of shampoo per pump press. Each press filled a 1/2 teaspoon measuring spoon. Two presses filled a 1 teaspoon measuring spoon. For my purposes of twice-daily eyelid cleaning, I use 1/2 teaspoon in the daytime, 1/2 teaspoon at night. (Calculations in Forecasting ... section.)
Depending on how much baby shampoo you use and for what purpose(s), this pump hack could result in significant savings of time, money, and trips to the store.
When the pumper baby shampoo is nearly depleted, switch out the pump to the press-fit cap. Invert the shampoo bottle in a larger bottle bottom so that gravity helps pull the shampoo down for dispensing.
The 13.6-oz Significance (Google AI Convo)
In an inquiry to Google, I asked "Do you know if superstores' private-label baby shampoos use the same or similar bottling and capping looks/methodology?"
Google AI excerpts:
Yes, private-label products share the exact same capping and bottling methodology. ... The 13.6-oz bottle is the most iconic, globally standardized silhouette for baby shampoo ... manufactured to directly clone the look and feel of national brands, they source identical packaging components. ...
manufacturers stick strictly to universal configurations like 24-410 or 28-400. ... seamlessly pivot from bottling baby shampoo to bottling body lotion without changing their capping machinery. ...
The industry baseline cap size for a 13.6-oz teardrop baby shampoo bottle is a 24-410 press-top (or flip-top) cap. Because Lubriderm's 24-oz value bottle also uses a 24-410 neck finish, the caps match seamlessly.
Baby Shampoo Pricing, Emphasis on 13.6-oz Size
Numerous superstores carry private-label clones of big-name products. My focus here is on the 13.6-oz baby shampoos. Johnson's Baby Shampoo is most prominent. For this size, my superstore sells Johnson's baby shampoo for $4.78 ($0.35 / oz), and the house brand, Hill Country Fare, for $2.84 each ($0.21 / oz), a significant price difference, IMHO.
My expectation was that other superstores charge less for their brands. Doing Google searches, eyeing prices and price/oz is a good idea. First off, Kroger seems to be in line with economy with Comforts baby shampoo 13.6 oz for $2.19 ($0.16/fl oz).
Publix and Safeway, however, were disappointing.
Publix: $5.53, $.0.41/oz]
Safeway (Signature Select/Care): $5.49, $0.40 /oz)
A Johnson's "Baby Shampoo" site shows links to merchants for pricing and additional details for the 13.6 oz size. Mull over the following:
Walmart. $4.78, 35.1¢/fl oz (excl shipping)
Target, $4.99 [$ .37/oz]
Walgreens, $6.99 [$ .51/oz]
CVS, $6.59 (48.5¢/oz)
Dollar General, $5.25 [$.39/oz]
Forecasting How Long the Pump-Hack Baby Shampoo Lasts
My new, unopened 13.6-oz superstore bottle of baby shampoo weighed 15.96 ounces. My empty bottle with cap weighed 1.53 ounces. After subtracting the packaging, the shampoo weighed 14.43 ounces, exceeding the listed fluid weight by .83 ounces (7% overfill).
My usage is 1/2 tsp, twice a day, thus, 1 tsp/day. Six teaspoons = 1 ounce. If calculating with the bottle's labeled amount, my shampoo should last 81 days. If calculating with the weighed amount (15.96) minus the packaging weight (1.53), the bottle could last 86 days.
Note: My forecasting estimates imply linear shampoo usage. Actually, a fuller container pumps out more fluid than when it becomes emptier. When I asked Google Ai about fullness of the originating container affecting the output amount, it provided significant terms and explanations "Head Pressure (Gravity Assist)", "Priming and Volumetric Efficiency", and "Check Valve' Delay and Drain-Back".
Key to forecasting how long your shampoo lasts is tracking measured amounts and the varied purposes. In any case, try the repurposed pump hack if you're interested in results for more optimal baby shampoo economy.
Thinking about Pump-Dispensing Lotions for Pump?
I Googled "Prominent brand names of lotions that use 24-410 neck threading pump dispenser". The reply listed Lubriderm, Vanicream, Eucerin, and Hemps lotions. Widening the inquiry, guessing that 24-410 standard might be common with pump lotions, I typed "heb pump lotions", which yielded six names.
At HEB online, my search for "pump lotion" yielded 15 items. Try a hands-on, on-site approach. Take a baby shampoo press-fit cap with you.
At the store's lotions aisle, hold the baby shampoo cap near a candidate pump lotion bottle. If the diameter is same or similar, unscrew the pump cap and check the bottle neck thread for 1 1/2 turns. High likelihood you can easily use the caps hack.
