Abstract: Pressurized medical Cup Device comprises a plastic cup containing liquid while a piston making more inside pressure on the liquid to have it go up through the straw. This method is offering a lot of help for the people who are suffering from a difficulty in sucking any kind of liquid because of disability problem, mouth surgery, tooth extraction or an king of problem that interfere with sucking liquid. Unfortunately, many patients suffer from ailments or disabilities that prevent them from drinking, even through a straw. As such, the patients, along with their care providers, can never be sure if the medicine was fully consumed or just ran down the patient's face. These same problems exist when trying to drink ordinary liquids such as water, juice, or the like as part of regular nourishment. Accordingly, there exists a need for a means by which individuals that have great difficulty when drinking from a straw can be afforded the ability to do so in an effort to address the concerns as described above.

Abstract: An improved device for dispensing toothpaste from a flexible tube using only manual pressure on the flexible tube. The device is formed to fit precisely the inner shape of the toothpaste tube and slides forward as the tube is manually squeezed from the outside. As the device moves toward the tube opening the toothpaste is expelled. Friction strips attached to the device on two sides come into contact with friction strips on the two interior sides of the toothpaste tube. As the device is propelled forward by manual pressure it is prevented from moving rearward toward the closed end of the toothpaste tube because of the friction strips. Thus as the tube is depressed and the toothpaste is expelled the flattened portion of the tube remains flattened and the tube is ready for the next use.
