Child-resistant closures (CRC) are a legal requirement in many jurisdictions to protect consumers and avoid accidents, especially among young children. These closures come in a variety of designs, such as push-and-turn, squeeze-and-turn, dual-function, and snap closures. While these safety measures are important, they can be frustrating for adults, especially those with arthritis or gripping difficulties. This article will provide some simple techniques to open different types of child-proof and tamper-proof caps, such as using thumbtacks, toothpicks, hot paper towels, or various tools like pliers or screwdrivers.
| Characteristics | Values |

| Child-resistant cap type | Push-down and turn |
| How to open | Push down on the outer cap to engage the inner one |
| Tools that can be used to open | Thumbtack, toothpick, small screwdriver, pliers, nutcracker, small knife, paper towel, scissors, can opener, hammer, nail |

What You'll Learn
Using a thumbtack to pierce the cap
Using a thumbtack to pierce the plastic cap of a retail product is a quick and easy method to open it. This technique is particularly useful for childproof caps, which can be challenging for adults to open due to safety measures.
To begin, it is recommended to use a flat-head thumbtack or a push pin. These options are simple, cost-effective, and unlikely to adhere to the cap's surface. Avoid placing the thumbtack in the center of the cap, too close to the edge, or in a position that is not directly aligned with the edge. Instead, insert the thumbtack halfway between the center and the edge. This technique is suitable for both plastic inner and outer caps.
If the outer cap is made of hard plastic, you may need to use a hammer or another hard object to tap the thumbtack into place. Alternatively, you can place the thumbtack on a hard surface, point-side up, and push the bottle down onto it. Using three thumbtacks spaced evenly around the edge of the cap can help maintain even pressure and prevent bending the thumbtack.
Once the thumbtack is in place, it pins the outer cap to the inner cap, allowing them to function as a single, regular cap. This small hole relieves the pressure needed to unscrew the cap, making it easier to open.
While this method is effective and time-saving, it is important to note that it may not be suitable for liquids or certain contents, as the metal tip of the thumbtack could react with the product inside. Additionally, always exercise caution when handling products that may contain hazardous materials, and ensure they are stored safely out of the reach of children.

Using a paper towel and hot water
If you are struggling to open a plastic cap, hot water can be used to loosen it. Firstly, run the bottle cap under warm or hot tap water for about a minute. This will make the plastic more flexible and slightly expand the cap, making it easier to unscrew. If you are worried about melting the cap or damaging the bottle, use warm water instead of hot.
After running the cap under water, dry it with a paper towel. Be careful not to burn yourself! Then, place the wet part of the paper towel over the cap and fold the dry parts over the wet parts. Vigorously twist the paper towel to open the cap. If you need a better grip, try wrapping a rubber band or a clean kitchen towel around the top of the cap, and then twist it off.
If the cap is too hot to grip with your bare hands, wrap a towel around the bottle before opening it. Alternatively, tap the cap against a hard surface to loosen it from the bottle. Hold the bottle firmly and hit the side of the cap against the edge of a countertop. If the seal around the cap won't break, try sliding the blade of a utility knife around the space between the bottom of the lid and the seal.

Using a small pair of scissors
First, ensure you have a sturdy pair of scissors that can cut through plastic. The scissors should be sharp and strong enough to cut through the plastic without requiring excessive force.
Next, identify the seal of the plastic cap. This is usually a thin plastic ring located just below the cap, attached by a perforated line. This is the area you will need to cut through.
Now, take your scissors and carefully position the blades as close to the cap's seal as possible. Place the sharp edges of the scissors in between the cap and the ring, aiming to cut through the perforated line. Be cautious to avoid slipping and cutting yourself.
Start cutting by using a gentle sawing motion, moving the scissors back and forth along the seal. You may need to apply some pressure, but be careful not to bend or damage the cap or bottle. Continue this motion until you have cut through the entire seal.
Once the seal is broken, you can use your hands to twist off the lid in a counterclockwise direction. If the cap is still difficult to remove, you can use the scissors to carefully cut through any remaining attached sections of the seal.
Remember to always exercise caution when handling sharp objects like scissors. It is recommended to have a firm grip on the scissors and a steady hand to avoid any accidental cuts or injuries.

Using a hammer and nail
Firstly, place the nail close to the edge of the cap, but not directly on the edge. If placed on the edge, the nail may slip between the caps and fail to catch the inner cap. Using a hammer, gently tap the nail into the cap. It is important not to use excessive force, as this may result in the nail bending or the cap breaking.
Once the nail has been securely lodged into the cap, a slight twisting motion can be applied while simultaneously pushing down. This will help to guide the nail through the cap and ensure that it does not slip. If the nail does bend, it can be straightened and reused by gently tapping it with the hammer.
For added stability, it is recommended to use three nails spaced evenly around the edge of the cap. This will distribute the force evenly and reduce the risk of bending the nails. With this technique, even if only one nail successfully penetrates the cap, it will be sufficient to open it.

Using a manual can opener
To open a retail plastic package with a manual can opener, you will need to use the tool to bite down around the outer edge of the packaging. Allow the blade to rotate and slice through the plastic layers. It is recommended to cut through three sides, so you can easily pry open the package and retrieve your product.
- Open the arms of the can opener by gently pulling them apart.
- Position the cutting wheel of the can opener on the outer edge of the plastic package.
- Close the arms of the can opener so that the cutting wheel is pressed against the plastic.
- Crank the handle of the can opener to rotate the cutting wheel, allowing it to slice through the plastic.
- Continue rotating the handle until you have cut through three sides of the package.
- Pry open the package carefully to access your product.
It is important to note that you should be cautious when using a manual can opener, as the sharp edges of the tool and the cut plastic can pose a risk of injury. Always be mindful of your hand placement and avoid placing your fingers near the blade or the cut edges of the plastic.

Frequently asked questions
This type of child-resistant closure requires you to push down and turn the cap simultaneously to open it. If you are unable to do this with your hands, you can try using a thumbtack. Place the thumbtack close to the edge of the cap and push down or twist it gently.
Try holding the lower ring with one hand and the cap with the other hand through a towel and exert force in opposite directions. You can also try to cut the connection places with a knife tip, but be careful not to injure yourself.
Yes, you can try prying the cap with a small screwdriver or similar tool to break the join between the cap and the ring. Alternatively, you can use a paper towel and hot water. Wet a paper towel with hot water, place it over the cap, and then twist vigorously.
