Abstract: A foldable container and a cleaning tool assembly are provided. The foldable container includes a foldable side wall disposed annularly. The foldable side wall includes two adjacent connecting parts connected through a flexible part. When the foldable container is unfolded, the connecting parts rotate around a fold part on the flexible part. A first abutting part and a second abutting part are respectively disposed on two sides of the fold part and are arranged on the flexible part or the connecting parts. When the foldable container is in an unfolded state, the first abutting part abuts against the second abutting part. The cleaning tool assembly includes a cleaning tool and the foldable container. When the foldable container is unfolded to be used, the first abutting part abuts against the second abutting part.

Abstract: A water wringing mop includes a wiping object and a rod body. The rod body is externally sleeved with a sleeve configured to ascend and descend along the rod body. The upper end of the wiping object is connected to the sleeve, and the lower end of the wiping object is connected to the lower end of the rod body. The lower end of the rod body is provided with a detachably connected compressing piece, the compressing piece fixedly connects the lower end of the wiping object to the lower end of the rod body, and the upper end of the wiping object is detachably connected with the sleeve. By arranging a distribution plate, when the sleeve falls, the wiping object can be fully dispersed under a guiding action of the distribution plate. A detaching tool is connected to the rod body in a clamping manner.

Abstract: The present invention provides a PEG-ACS/M-siRNA nanocomposite application, and method for reducing the histamine content during fishmeal storage thereof. A small interfering ribonucleic acid (siRNA) is designed and prepared according to a histidine decarboxylase gene of Morganella morganii (Morganella morganii subsp. morganii KT), and the histidine decarboxylase gene has a sequence of SEQ ID No: 1. A PEG-ACS/M-siRNA nanocomposite is prepared by using a PEGylated arginine-modified chitosan as a carrier. A PEG-ACS/M-siRNA nanocomposite is added to fishmeal in a certain ratio. The method for reducing the histamine content during fishmeal storage has a significant inhibitory effect on the histamine content during fishmeal storage, and can reduce the histamine content in fishmeal by 49%-53%, which has great significance for the control of biogenic amines in fishmeal in the feed industry.

Abstract: A suitcase and a manufacturing method thereof are disclosed. An upper case shell and a lower case shell are obtained, and a flexible material is fixedly connected to the upper case shell and the lower case shell. When the suitcase is assembled, elastic parts are compressed to install two ends of rods on installation parts of the upper case shell and the lower case shell, and a resilience force from the elastic parts is applied to the rods to drive the upper case shell and the lower case shell to be away from each other, and the flexible material connected to the upper case shell and the lower case shell is driven by the upper case shell and the lower case shell to be tensioned.
