A fluid dispenser includes a lid that defines an opening and that includes a first sealing element. The fluid dispenser further includes a flexible fluid delivery component that defines an interior fluid channel. The flexible fluid delivery component includes a second sealing element configured to cooperate with the first sealing element of the lid to form a fluid-tight seal between the flexible fluid delivery component and the lid and a valve element configured to cooperate with the opening in the lid to regulate an airflow through the opening in the lid.

A method for manufacturing flexible paper straws and flexible paper straws are revealed. The method includes the steps of preparing a paper tube which is a spiral tube by glue and paper, inserting a support shaft into the paper tube axially, placing the paper tube with the support shaft between a first roller and a second roller before curing of the glue while the first and second rollers are in parallel and having a plurality of circular grooves on a cylindrical surface thereof, rolling the paper tube by the first and second rollers to form a corrugated portion on a part of the paper tube, squeezing the corrugated portion to compress the corrugated portion for a period of time for curing the glue and holding shape of the corrugated portion, and removing the support shaft to get a flexible paper straw which is bendable at the corrugated portion.

A method of making a paper straw with a bend includes coating a strip of paper with polyethylene on a first side and a second side of the strip of paper; cutting the strip of paper to a desired length; providing a spring apparatus of a predetermined length; rolling the strip of paper around the spring apparatus such that the strip of paper partially overlaps with itself to form a straw, the polyethylene holding the strip of paper in a rolled position; applying steam to the straw; and bending the straw to create a bend, the straw remains bent; and removing the spring apparatus from the straw.

A hydration system includes a liquid reservoir, a reservoir coupler, a tube, a hydration valve (e.g., bite valve), a tube coupler (e.g., quick connect), and a flow-restricting device (e.g., check valve). The tube comprises a first end having the hydration valve, a second end for coupling to the liquid reservoir, and the flow-restricting device interposed between the first and second ends.

The invention discloses a recycling dietary straw, this dietary straw comprising a hard rubber tube portion and a soft rubber tube portion. The hard rubber tube portion and the soft rubber tube portion are connected head to tail. The joints between 1-1 and 1-2 is sealed. The dietary straw can bend along the soft rubber tube portion to make the dietary straw in a folded state. The invention further discloses a special storage box, which can store the dietary straw. The outside wall of the dietary straw is sprayed with an anti-oxidation layer, well the anti-oxidation layer is sprayed with a photocatalyst layer. The invention adopts recyclable materials to provide a convenient, safe and reusable dietary straw.

The present invention generally relates to a printed paper straw, process of manufacturing, and method of use. The present invention also relates to a package of straws that are uniquely identifiable by an easy-to-read text or drawings located on the external surface of each straw.

This present invention relates to a flavor dispensing drinking straw device designed to retain and dispense an appropriate amount of flavoring, syrup and/or medicine into a beverage as per the desires of the users. The device comprises a topper having an internal cavity that holds a predefined amount of flavoring, syrup and/or medicine that the user can dispense through a spiral straw by simply and gently squeezing the topper, wherein the user can then consume the flavored or medicated beverage through a second tubular straw in a traditional manner. The uniquely designed straw device is both environmentally safe and reusable. Additionally, the topper can be refilled with the flavor, once the stored flavor is exhausted. The flavor infusing straw offers a more enjoyable and delicious drinking experience, and can be used with a variety of beverage containers.

A malleable metal straw. The malleable metal straw has an elongated member with a metal sidewall and a first open end and a second open end. An interior region has a liquid permissible cavity from the first open end to the second open end wherein at least a portion of the metal sidewall is sufficiently thin to allow the elongated member to bend under hand strength force. The malleable metal straw can further have a support structure within the interior region.

The invention relates to a drinking device for the retronasal perception of an aroma substance. The drinking device comprises a liquid reservoir that is fillable with drinking liquid, a mouthpiece with a mouth end, a transport tube for drinking liquid with an inner cavity which provides a flow connection between the liquid reservoir and the mouth end of the mouthpiece, and an aroma container for adding an aroma substance to an air flow flowing through the aroma container. The aroma container includes at least one air outlet opening which is in flow connection either with at least one aroma inlet opening into the inner cavity of the transport tube or in flow connection with an aroma channel extending up to the mouth end of the mouthpiece. The liquid reservoir may include an attachment that is to be attached to the body or clothing of a user or to a bag to be worn on the body. The transport tube may have a length of at least 15 cm and preferably a length of at least 20 cm.

Apparatuses, systems, and methods are presented for a buildable drinking straw. A segment of a drinking straw is hollow. A segment has a narrow end and a wider end. A wider end of a segment of a drinking straw is opposite a narrow end of the segment of the drinking straw and has a wider diameter than the narrow end of the segment of the drinking straw so that the segment of the drinking straw tapers in diameter from the wider end to the narrow end of the segment of the drinking straw.
