A reusable drinking straw system, comprising an upper cover a lower cover, a flexible straw, wherein the lower cover is internally provided with a baffle wall and a central pole, wherein the lower cover further comprising a positioning wall, wherein a straw groove is formed between the upper cover, wherein the flexible straw is capable of being disposed in the straw groove, wherein the flexible baffle wall further comprising an opening, wherein the flexible straw has a first distal end and a second distal end, wherein the first distal end and second distal end of the flexible straw protrudes pass the opening and wedges between the baffle wall and the central pole.

The present disclosure generally relates to a paper straw comprising a flexible portion having a compressed and an extended state, wherein the paper straw comprises a stretchable paper. The disclosure also relates to a drinking kit comprising the paper straw and to a process and a machine equipment for manufacturing the paper straw.

Described herein are embodiments of systems and apparatuses that include a drinking vessel with a hygienic straw. In an embodiment, the apparatus includes a container and a lid, where the lid is configured to engage an opening of a container to retain the liquid within the container. The lid may further include a drinking straw for use in extracting liquid from the container. The straw may be attached to the lid so that it can be covered, uncovered, and/or otherwise accessed without the need to physically touch the straw itself.

The present application discloses an adjustment device for a drinking straw and a drinking straw component. The structure of the adjustment device includes a first elbow and a second elbow, wherein one of the first elbow and the second elbow is partially insertable into the other of the first elbow and the second elbow; a slot is provided on the wall of the first elbow and extends along a length of the first elbow; a protrusion is provided at an end of the second elbow close to the first elbow; and the protrusion is slidable in the slot of the first elbow along its length, so that the first elbow and the second elbow can be slid against each other. The present application can adjust the sipping angle of the straw and pierce through a cover of a wrapped drink purposed for inserting the corresponding straw.

A drinking straw is marked to describe a particular type of drink in order to aid users to quickly and accurately identify drink contents. For example, the drinking straw may include text indicating soda, tea, coffee, or other designation of a drink. The drinking straws described herein provide servers, bartenders, and consumers with an easy-to-use tool for projecting what type of drink is in any cup, without having to rely on the drink's look or taste.

A drinking glass for serving distilled alcoholic drinks includes a bottom and a wall, the wall including a choke. At the choke, a cross-sectional area of the wall is smaller than a cross-sectional area of the wall at an upper edge of the wall, which is, at the rim of the drinking glass. The wall is provided with at least one formation for the distilled alcoholic drink, on an inside face of the wall, between the choke and the upper edge of the wall.

Provided is a poly(3-hydroxybutyrate) resin tube including a poly(3-hydroxybutyrate) resin, the tube having a wall thickness of 0.1 to 0.6 mm. The difference between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin is preferably 10° C. or higher. Preferably, production of the tube includes the step of melting a poly(3-hydroxybutyrate) resin in an extruder, then extruding the resin from an annular die, and introducing the resin into water, the annular die temperature being set to a temperature between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin.

A foldable straw includes a first segment, a second segment, and an intermediate segment. The first segment includes an elongated length and a cavity extending through the elongated length and has a first durometer value. The second segment includes an elongated length and a cavity extending therethrough and has a second durometer value. The intermediate segment is operably coupled with and positioned between the first segment and the second segment and includes an elongated length and a cavity extending therethrough and has an intermediate segment durometer value. The intermediate segment durometer value is less than the first durometer value and the second durometer value such that the collapsible straw is foldable within the intermediate segment.

A portable straw, including the limiting component, the adjusting component and the straw body. The said limiting component includes first limiting disc and second limiting disc which are mutually symmetrical and kept at a given gap. Both limiting discs are connected through a cylinder, and the first limiting disc, the second limiting disc and the cylinder are in a same axis, which eliminates the weakness of the prior straws of the environmental contamination, inconvenient carrying and fixed shape.

Described herein is a container for a beverage as well as a structure to allow a user to drink the beverage contained therein. In at least one embodiment, there is a beverage container and straw combination that allows for a unique transportation of the liquid through the straw. The straw may be configured to pass through a lid of the beverage container multiple times and pass through a hollow or channel positioned above a lid of the beverage container.
