Abstract: The disclosure provides an anti-pollution bottle cap comprising a cap body, a liquid drainage one-way valve and an air intake one-way valve. A liquid drainage hole and an air intake hole are disposed in the cap body and both communicated with an inside of the cap body. The liquid drainage one-way valve is disposed in a space enclosed by the cap body. The liquid drainage hole is blocked by the liquid drainage one-way valve in one way so as to be opened during toppling operation. The air intake one-way valve is disposed in the space enclosed by the cap body. The air intake hole is blocked by the air intake one-way valve in one way so as to be closed during toppling operation. In application, the anti-pollution bottle cap will be installed on a bottle for matched use, so that a user can normally drain liquid through the liquid drainage hole only by squeezing the bottle.

Abstract: Disclosed is a single-material all-plastic lotion pump, including a main body, a pressing head, a barrel body, a one-way liquid outlet mechanism and a tubular spring; a guide hole communicates the inside of the main body from two opposite ports thereof; the press head is in an inserted connection with one port of the main body in a pressable manner, and is provided with a liquid outlet channel; the barrel body is in an inserted connection with the other port of the main body, and has a liquid inlet channel in a bottom wall; the one-way liquid outlet mechanism passes through the guide hole, and has an import channel and an export channel; and the tubular spring is compressed between the one-way liquid outlet mechanism and the bottom wall of the barrel body, and is connected and communicated with the import and liquid inlet channels at both ends, respectively.

Abstract: The disclosure provides a single material all plastic lotion pump and a storage bottle of application thereof, and the pump includes a plastic pump casing, a plastic pressing head, a plastic cylinder casing and a plastic double piston mechanism; the plastic pump casing is provided with a material delivery tube that communicates between the inside and outside; and the overall material of the disclosure is plastic, soft rubber, etc., there is no need for disassembly operation in case of recycling, and the full plastic lotion pump can be directly recycled, which greatly improves the recycling efficiency, greatly reduces the recycling cost, and effectively solves the problem of difficult recycling of the existing lotion pump head.

Abstract: Disclosed are a single-material all-plastic pump and a storage bottle applied thereby, mainly including a plastic pressing head, a plastic pump casing, a plastic piston mechanism and a plastic reset spring; the plastic pressing head is in a pressable connection with the plastic pump casing, and has a discharge hole which is connected and communicated with a discharge end of the plastic piston mechanism; the plastic piston mechanism is disposed inside the plastic pressing head and the plastic pump casing, has a feed end which is connected and communicated with a material guide hose, and is used to control the opening and closing of the discharge hole and the material guide hose; the plastic reset spring is sleeved outside the plastic piston mechanism and compressed between the plastic pressing head and the plastic pump casing; and therefore, materials used in the solution are generally plastic, soft rubber, etc.

Abstract: A multi-terminal cooperative play method for a multimedia file, and a related apparatus and system are disclosed. A multi-terminal cooperative play system includes a master cooperative player, a play group management device, and a slave cooperative player. The play group management device allocates a cooperative play identifier and play position information according to a cooperative play request sent by the master cooperative player, and allocates play position information according to a cooperative play joining request sent by the slave cooperative player; the master cooperative player sends multimedia file information to the play group management device; the slave cooperative player obtains the multimedia file information; and the master cooperative player sends a play command to the slave cooperative player, so that the master cooperative player and the slave cooperative player can play, at start time of a cooperative play, a multimedia file c.

Abstract: A housing for an electronic device is disclosed, the housing comprises a base layer and a transparent film layer overlapped in the base layer, the film layer includes an inner surface abutting the base layer and an outer surface having ridges protruding thereform. The housing is formed by injection molding a molten plastic material over the transparent film layer, the ridges are formed on the transparent film layer by the molten plastic pressing the transparent film layer in injection molding. It is also disclosed a mold for making the housing and a method to make the housing.

Abstract: A housing comprises an exterior coating and a substrate. The housing further comprises a first conductive coating, a light emitting coating and a second conductive coating formed between the exterior coating and the substrate. The substrate formed on the second conductive coating by molding. The first and the second conductive coatings include electric contacts. An electronic device using the housing is also described there.
