Foam-in-bag systems and components thereof

A system includes a dip tube, a feed line, and a check valve. The dip tube is inserted through an opening in a source of chemical precursor and into the chemical precursor in the source. A portion of the feed line is located in the dip tube. The feed line passes out of the dip tube. The chemical precursor is capable of flowing out of the source through the feed line in a downstream direction. The check valve is located in the portion of the feed line in the dip tube. The check valve permits the chemical precursor to pass substantially only in the downstream direction. The feed line is coupled to a transfer pump that draws the chemical precursor out of the source through the portion of the feed line in the dip tube.

Heat fusing devices, smart trash receptacle and methods for controlling heat fusing temperature

The present invention discloses a heat fusing device for a smart trash receptacle, including: a heating wire for fusion-cutting and thermally sealing an open end of a trash bag, the heating wire being connected to a heat-fusing circuit; a base having heat-resistant and insulating properties, the base having a first end surface on which the heating wire is arranged; and a control mechanism communicatively coupled to the heat-fusing circuit for control thereof. The present invention also discloses a smart trash receptacle incorporating the heat fusing device and a method for controlling a heat fusing temperature. With the present invention, during automatic bagging by the smart trash receptacle, good contact between the heating wire and the trash bag can be ensured while preventing adhesion of the trash bag. This results in improved sealing quality and enables the fulfillment of two tasks, i.e., thermoplastic sealing and thermal fusion-cutting, in the same action of the heat fusing device. As a result, higher automatic bagging quality and reliability are obtainable at lower bagging control difficulty and reduced bagging cost. Moreover, control in the system is simplified, and the stability and reliability of the system are increased.

METHOD FOR MANUFACTURING BIODEGRADABLE PILLOW TEA BAGS CONTAINING WHOLE LEAF TEA
20230058750 · 2023-02-23 ·

A biodegradable whole leaf pillow tea bag is provided, along with a system and method for manufacturing biodegradable whole leaf pillow tea bags. The method for manufacturing the whole leaf pillow tea bags includes the steps of providing a biodegradable infusion substrate having two opposing edge; creating a sleeve from the biodegradable infusion substrate by infusing the two opposing edges of the substrate together and closing the sleeve at its bottom; placing whole leaf tea in the bottom of the sleeve; vertically feeding the sleeve containing the whole leaf tea into a heat sealing machine that will, at predetermined intervals create heat seals across the sleeve to create pillow bags; cutting the pillow bags from one another across the heat seal. In one example, the biodegradable infusion substrate may contain hemp and/or the whole leaf tea may be infused with CBD oil or other supplements. The same method of manufacturing may be used to create a biodegradable pillow bag containing coffee.
