  • Patent number: 11639482
    Abstract: A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules functioning as precursor molecules to induce tribopolymerization and forming in situ protective tribofilm with desirable robustness and low shear resistance. Each lubricant additive molecule includes one or more surface-active groups attractable to target surface, and a carbon containing component operable connected to the one or more surface active groups. The carbon containing component comprise a carbon ring structure having a high ring strain that is metastable and activatable with a ring-opening reaction. A less stable carbon ring structure is more readily activated to the intermediate state, preferable to form more active fragments. Increasing the adsorption strength further is beneficial to prolonging the residence time of additive molecules on the target surface, thereby facilitating the dissociation of molecules and subsequent polymerization.

  • Patent number: 11622880
    Abstract: A packaged condom applicator apparatus is provided with a condom supplied therein. The apparatus has the following: a condom holder where the base of the condom can be inserted and secured in place while protecting the condom body as packaging; an apparatus clip or unhinged clip that presses down on the condom tip to create a reservoir and an airtight seal during condom application. This helps avoid the creation of air bubbles. Using the condom holder, the user simply slides the condom along the erected penis to apply the condom on and removes the condom holder, opening the condom tip clip automatically, and ejecting the whole apparatus after the condom is applied onto the penis. Using this self-applicable apparatus, the user can quickly use the condom with less effort, distraction, and manual intervention.
