Abstract: A dual-use lid includes a cover. The cover has a protruding segment, an annular wall, and a circular body. The protruding segment is formed on the cover. The annular wall extends from the protruding segment. The circular body is formed on the annular wall. The dual-use lid can be combined with various containers. An annulus is detachably mounted on the cover to form a space for loading food, and users are able to have drink and food at the same time. In addition, the cover and annulus are detachable, such that the cover and annulus can be transported and stored in an increased amount.

Abstract: A self-closing water-saving valve assembly has a casing, a seat, a pushing rod, a closing member and a stand. When said valve assembly is switched off, the closing member and the stand slow down the closing movement into a gradual manner, which can effectively reduce positive and negative pressure waves generated in the water pipe. Noises and damage to the water pipe are also prevented. Besides, the pushing rod is moved down by gravity and slight water pushing, which eliminates the problems of wear and speeded-up movement of the pushing rod. Therefore, the valve assembly has prolonged lifespan. In addition, the water pressure is not directly applied on the pushing rod and only slight water pushes the pushing rod such that it is easier for a user to push the pushing rod to switch on the valve assembly.

Abstract: A foldable container module includes a body and a foldable container. The body has a sidewall and a room. The foldable container has a panel, multiple folding line sets formed on the panel, and a joint. The foldable container can be transformed by folding along the multiple folding line sets. The joint connects to the sidewall of the body. The foldable container module can be held in one hand by a user, and the other hand of the user can swing freely or take the solid food from the foldable container, such that the user can also suck the liquid from the body by the straw at the same time. Moreover, when the foldable container module is to be stored, the user can fold the foldable container along the multiple folding line sets to reduce a volume of the foldable container.

Abstract: A cap container includes a tank, a conical protrusion, and a stepped coupling. The tank includes an upper rim, a bottom opposite to the upper rim, and a hole formed through the bottom. The conical protrusion includes a lower end, an upper end, an inner wall extending from the lower end to the upper end and defining a channel, and an engagement part formed at the inner wall near the lower end. The channel passes through the lower end and the upper end and communicates with the hole of the tank, and the channel can receive a straw. The stepped coupling has at least one annular groove and is formed at the bottom of the tank. The cap container can be filled with solid food and combined with a top a commercially available drink container such as a bottle or a cup filled with liquid by the engagement part of the conical protrusion.

Abstract: A water-saving valve assembly has a base, a control valve device and a buffer device. The control valve device is mounted in the base. The water-saving valve assembly is mounted on an exit of a water pipe. Users can control the flowing out or stopping of water in the water pipe via the control valve device. The buffer device provides a gradual effect of switching off and can effectively reduce positive and negative pressure waves generated in the water pipe. Noises and damage to the water pipe are also prevented.

Abstract: A water controlling valve includes an outer sheet, an end cap and a control valve group. The control valve group is disposed between a flowing bore in the outer sheet and a water bore in the end cap. The water controlling valve is connected with the outlet of a water tube. When the control valve group is pushed upwards, the water bore in the end cap and the flowing bore in the outer sheet are closed in a predetermined sequence, then the water in the tube will not flow out. When the control valve group is pushed downwards, the flowing bore in the outer sheet and the water bore in the end cap are opened, then the water will flow out. When the water is stopped, the occurring positive or negative pressure wave is lowered, and then the vibration and the raspy noise will be avoided.

Abstract: An adjustable water valve of time-controlled type consists of an inner shell and a time-controlled apparatus. The time-controlled apparatus is disposed inside the inner shell and includes an elastomer and a push rod. The elastomer is disposed between a support lid and the push rod. When the push rod is pushed into the inner shell, the water valve is opened, so the user can wash with the water ejected. After certain time, the water pressures are balanced and the elastomer which has been compressed will push the push rod back to its initial position to close the valve.

Abstract: A spout for foaming and saving water has a shell, a foaming assembly mounted in the shell, a sieving assembly mounted on a faucet end of the foaming assembly and a regulator mounted through the foaming assembly. The foaming assembly has a sleeve, a distributor mounted in the sleeve, a foaming ring mounted between the sleeve and the distributor and an inlet valve mounted on a faucet end of the sleeve. The spout is mounted on an outlet of a faucet to allow water to flow through the sieving assembly and the foaming assembly and mix with air to foam to provide foaming water flowing out of the spout. Impurities in the water do not clog the foam assembly and water flow is regulated with the regulator selectively mounted in a water flow hole of the inlet valve.

Abstract: An ear curette has a shaft and a cleaning portion. The shaft has a distal end. The cleaning portion has a disk and a bar. The bar has a distal end and a proximal end. The proximal end of the bar is narrower than, is formed on and protrudes from distal end of the shaft. The disk is formed on the distal end of the bar. When in use, the disk of the cleaning portion can be deposited in the ear canal first and then pulled out of the ear canal to scrape out earwax and is easily cleanable.
