This disclosure relates to a cover and a water container using the cover. The cover comprises a cover body, a blocking member and a sealing assembly. The cover body is provided with a water outlet. The blocking member is slidably arranged on the cover body and provided with a blocking portion for blocking the water outlet. The sealing assembly is arranged on an inner side of the cover body and comprises a force-bearing member and a sealing sheet connected to the force-bearing member and moving with the force-bearing member. The force-bearing member is in contact with the blocking member. When the blocking member slides back and forth along the cover body, the force-bearing member moves accordingly toward the inner side of the cover body or toward an outer side of an upper end surface of the cover body, respectively. The sealing sheet widens a gap of a fluid channel communicated with the water outlet when the force-bearing member moves towards the inner side of the cover body, and the sealing sheet gradually narrows the gap of the fluid channel to a sealed state when the force-bearing member moves towards the outer side of the upper end surface of the cover body. In this way, the user can open or close the water outlet by sliding the blocking member simply.

The present application generally relates to devices and methods for transporting items, and it more specifically relates to insulated carriers for use in carrying temperature-controlled items such as beverages and food.

A water-disinfecting apparatus includes a vessel with a cathode, an insert with a photoanode, an ultraviolet light source configured to be positioned in the insert, and a power source. The cathode forms an electrically conductive layer on an inner surface of the vessel. The photoanode is configured to be positioned in the cathode. The power source is configured to be operably coupled to the cathode, the photoanode, and the light source.

A modular bottle (e.g., for holding liquid or dry storage contents) and its various assemblies, components, and structures are provided. The bottle can be flexible or rigid and is dynamically modular to be particularly useful for outdoorspeople, military personnel, travelers, pet owners, and the like. The bottle is a double-ended device capable of being modified or expanded with various caps, filters, spouts, compartments, and like accessories.

A bottle having a water volume measuring function comprises a bottle-lid, a bottle-body, and a measure module disposed in the bottle-lid which comprises at least a micro controller unit, a memory unit and a sound wave transceiver unit. The memory unit stores a lookup table with corresponding relationships between a plurality of frequencies and remained water volumes in the bottle-body. The sound wave transceiver unit emits sound waves with sweeping frequencies towards the bottle-body and receives reflected waves. The micro controller unit determines if any frequency of the sound waves is an air-resonance frequency according to the energy level of each of the reflected waves. When a sound wave frequency is determined as an air-resonance frequency, the micro controller unit obtains the corresponding remained water volume by checking with the air-resonance frequency in the lookup table and users can view the remained water volume without opening the bottle-lid.

The invention is a fluid container, such as a flask or canteen, positioned in previously unused spaces found in the housing of a measuring tape mechanism. The present invention possesses a fluid container or vessel place inside the external housing of a measuring tape component (with an opening and cap), which simultaneously encloses an internal integrated spooled measuring tape with spring-loaded retracting measuring tape with a locking mechanism. The present invention allows for the simultaneous placement of a fluid container inside previously unused space in a measuring tape housing to store fluids in an efficient and effective manner without requiring two separate vessels or components, to allow for a more efficient and effective incorporation of a useful fluid vessel in previously unused space in a measuring tape mechanism to provide storage of hydration or medicinal fluids in a more efficient and effective manner on construction or work sites.

A container for holding and delivering liquids is disclosed. A method of making the same is disclosed. The container can have a molded container top, a molded container bottom, a flexible film reservoir, and a handle extending from the container top to the container bottom. The reservoir can be laterally exposed around the entire circumference of the reservoir along a part of the longitudinal length of the reservoir. A thermally insulated reservoir system is disclosed. The reservoir system can have a bag having a multi-layered bag wall. The bag wall can have a first layer sealed to a second layer. The volume defined between the first layer and the second layer can be partially or completely filled with a fluid insulator, such as air or saline solution. The volume defined between the first layer and the second layer can also or alternately be partially or completely filled with a solid insulator, such as a matted fiber layer.
