One embodiment provides a disposable tool. The disposable tool may include an exterior layer disposed over one or more dissolvable layers forming a shape of the disposable tool. The exterior layer is coated with an impermeable coating. The disposable tool includes one or more segments that are not coated with the impermeable coating. The disposable tool may be utilized for consumption of food or liquids or as an applicator, such as a tampon applicator.

A method for dielectrically heating foamable composition to foam and set the composition is described. In particular, radio frequency (RF) heating is used to heat the foamable composition to provide insulation in the manufacture of an article.

A paper container including an aluminum liner, which protects people's health from environmental hormones in a paper container is provided. Also provided is an eco-friendly paper container wherein, in the case of using a water-based adhesive, paper can be easily separated from the container by immersing the container in water, to allow easy paper recycling. The paper container conserves forests and thus can contribute to the prevention of climate change. Further, the container is a disposable or multiple-use food container that can be used for various foods and beverages such as coffee, beer, beverages, cup noodles, cup rice, soup, and stew. The container helps human health and global environmental conservation.

The present disclosure is directed to recyclable, composite container assemblies with improved characteristics resulting from a combination of raw materials, structural design, systems, and methods for sealing a paper-based closure to a paper-based container body. The container assemblies demonstrate superior performance and seal properties, such as very low oxygen transmission rates and high resistance to bulging and/or damage due to high pressure differentials. The disclosed container assemblies, manufactured at high speeds, have been optimized by increasing the shelf-life of food products stored therein, while minimizing any non-paper materials such that the container assemblies qualify as recyclable mono-material.

A paper cup of a dual structure according to one embodiment of the present invention comprises: an inner paper part having a plurality of diameter adjusting portions formed at predetermined angle intervals on one surface; a drink receiving part formed extending from one end of the inner paper part and bending formed into the inner portion of the inner paper part; and a drinking part formed at a boundary between the inner paper part and the drink receiving part and curled in a radially outward direction of the drink receiving part.

A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.

Degradable water- and oil-resistant article is made of chitin and contains water-activated chitin-degrading enzyme or enzymes. Initially supplied in an inactive lyophilized (dry) form, the enzyme or enzymes upon exposure to water present in ambient environment degrade chitin-based article to chitosan, a benign compound. Several article embodiments presented, some with water ingress retardant features.
