Shower curtain liner with multiple hook rows and tear‑off bottom

A single-panel shower curtain liner with several horizontal rows of hook apertures at the top so you can hang the liner at different heights, and stacked perforation rows at the bottom so you can tear off sections as they get moldy or dirty. The liner also includes magnets at the lower edge to hold it to the tub and attachment means (snaps/Velcro/buttonholes) near the top to add a decorative outer panel; aimed at homeowners and renters who replace liners regularly.

(57) What the patent covered

The independent claim covers one single downward panel that has at least two vertically aligned rows of hook apertures at the top so one hook can be placed through aligned apertures to change hanging height, plus stacked perforation rows at the bottom designed to be torn away one row at a time to shorten the liner, and a bottom edge sized to reach the tub or shower floor. A dependent element and another independent claim add at least three top rows and a means to attach an outer cover near the top.

The distinctive part: Top has multiple vertically aligned hook-aperture rows for selectable hanging height and bottom has removable perforation rows for reuse as a fresh hem.

Making it

likely cut/poly-weld or heat-seal plastic panel, embed or weld magnetic strip(s), punch stacked rows of reinforced apertures, add snaps/Velcro by heat-press or ultrasonic welding, pack; hooks and decorative outer panel sourced separately

Materials: PVC or PEVA shower-safe plastic, Magnetic strips (ferrous-backed or encased magnets), Snap or Velcro attachment hardware, Corrosion-resistant metal or plastic curtain hooks

Manufacturability 4/5. Mostly sheet plastic fabrication (die-cut, heat-seal), some added hardware (magnets, snaps) and simple assembly; standard curtain‑liner factories can produce it.

Is anyone buying?

Comparable products are on sale; this exact design wasn't found. Typical retail price: $5–$17. Magnets at bottom are common in many current liners; both listings show magnetic/heavy-weighted bottoms to help keep the liner in place.

This demand check was run with a web search in the week of Oct 5, 2026. Listings change often, so treat it as a starting point for your own research.

Who buys it: homeowners and renters replacing liners frequently

Before you make it

We didn't find any related continuation or divisional patents still in force, although that doesn't rule out design patents, trademarks or unrelated patents covering the same product.

Practical risks: crowded, low‑cost market for disposable liners; magnets must be sealed and corrosion‑resistant for wet use and perforation rows must not weaken top/side integrity.

Owners occasionally revive lapsed patents (about 1.5% are), and this page is a research lead rather than legal advice, so get a freedom-to-operate opinion before you manufacture anything.

Claim 1, as granted

1. An improved shower curtain comprising: a single liner panel having a top horizontal edge and a bottom horizontal edge, said top edge of said single panel including a plurality of rows of spaced, horizontally extending apertures, each individual row of spaced apertures being designed for the placement of multiple shower rod hanging hooks, one hook per aperture, in order to hang the single panel from the row of horizontal apertures onto a curtain rod, said single panel having a first row of spaced apertures extending above and parallel to a second row of apertures directly beneath, the apertures of the first row and the second row aligning vertically with one another to place a hanging hook into the vertically aligned apertures of two or more rows for changing vertical length of the single panel, said bottom edge designed to contact with a sidewall of the tub or a floor of the shower if no tub, said bottom edge having a plurality of horizontally extending, perforation rows stacked one above the other, said perforation rows being designed to be purposefully torn away at a bottom of the preceding row, one row at a time, for making a new bottom row of the single liner panel.
