SHOT STRAWS AND METHODS FOR MAKING AND USING THE SAME

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Patent Application No.

63/220,900, filed July 12, 2021, and U.S. Provisional Patent Application No. 63/279,904, filed November 16, 2021. U.S. Provisional Patent Application Nos. 63/220,900 and 63/279,904 are incorporated herein by reference in its entirety.

TECHNICAL FIELD

[0002] This disclosure relates generally to an apparatus for drinking liquids.

BACKGROUND

[0003] Taking shots with friends in social events is a popular bonding experience. However, taking a shot all down in one gulp may be challenging for some people, and they may take chasers after the shots to reduce the strong taste. Further, a risk of choking exists for taking a shot directly from a glass. Therefore, a need exists for a new apparatus with a straw for drinking a shot with a chaser together while not mixing the shot and chaser evenly.

DESCRIPTION OF EXAMPLES OF EMBODIMENTS [0027] Various embodiments can include an apparatus. The apparatus can include a straw and a one-way valve. The straw of the apparatus can include a top end, a straw body, and a bottom end opposite the top end and configured to be placed in a container (e.g., a bottle, a cup, or a mug). An exterior surface of the straw body can include branding information (e.g., a trademark, a service mark, the name of the seller or distributor, etc.) for promoting the apparatus or the supplier for the apparatus. Further, the one-way valve of the apparatus can be removably coupled to the bottom end of the straw and configured to allow liquid (e.g., water, juice, beer, soda, etc.) in the container to enter the straw when a suction force is created at the top end of the straw. Examples of the one-way valve can include a cross-slit valve, a duckbill valve, a spring valve, a tension valve, or any other suitable one-way valves.

[0028] In a number of embodiments, the apparatus further can include a top cap removably coupled to the top end of the straw. Examples of the top cap can include a threaded lid, a shooter lid, a hinged flip cap, a twist cap, and/or a squeeze lid. In some embodiments, the top cap further can include a top one-way valve configured to allow a second liquid (e.g., an alcohol shot or a wellness drink) in the straw to exit the straw from the top end when the suction force is created at the top end of the straw. The top one-way valve can include a cross-slit valve, a duckbill valve, a spring valve, a tension valve, or any other suitable one-way valves. In many embodiments, the apparatus also can include a film (e.g., a heat induction foil, etc.) configured to removably seal the top end of the straw.

[0029] In several embodiments, the apparatus further can include a bottom cap removably coupled to the one-way valve and configured to seal the one-way valve. The bottom cap can include a quarter-turn threaded cap, an end cap, or any other suitable caps. The bottom cap also can be configured to seal the one-way valve by any suitable components, e.g., a silicone or rubber lid. In some embodiments, the apparatus additionally can include the second liquid in the straw body. Further, the apparatus and/or its components each can have any suitable dimensions, volumes, configurations, and/or materials. For example, the apparatus can include a height of approximately 9 inches (22.86 centimeters (cm)), an outer diameter of approximately ¼ inch (0.635 cm) to ¾ inch (1.905 cm), and/or a volume of approximately 1 fluid ounce (29.57 milliliters (ml)) to 3 fluid ounces (88.72 ml). The straw body further can include clear plastic, thermoplastic, and/or any other suitable materials.

[0030] Various embodiments include a shot straw. The shot straw can include a straw and a one-way valve. The shot straw, and/or its components (e.g., the straw and/or the one-way valve), each can be similar or substantially identical to the apparatus or shot straw, and/or its corresponding components, in any of the other embodiments described herein. The straw can be made of any suitable materials and have any suitable shapes, dimensions, and/or ornamental features, etc. For instance, the straw can be made of rigid clear plastic or thermoplastic, etc. Examples of such plastic or thermoplastic can include polyethylene terephthalate (PETE or PET), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), polypropylene (PP), extruded polystyrene (PS), polycarbonate (PC), polylactide (PLA), acrylic, acrylonitrile butadiene styrene (ABS), fiberglass, and nylon. The straw further can include branding, logos, aesthetic designs, etc. printed, etched, or attached to the exterior surface of the straw. The straw can be a cylindrical tube of any suitable dimensions and thicknesses. In some embodiments, the straw can be thicker than a normal disposable straw. An exemplary straw can have a height of a normal straw, such as 9 inches (22.86 cm), and an outer diameter between 1/4 inch (0.635 cm) and 3/4 inch (1.905 cm).

[0031] In a number of embodiments, the one-way valve of the shot straw can be placed inside the straw, at or near the bottom end of the straw. The one-way valve can be configured to allow liquid to flow from the bottom end of the straw toward the top end of the straw, but not the other way around, when an upward pressure is caused by a user sucking from the top end of the straw. Examples of the one-way valve can include a food-grade cross-slit (x-slit) one-way valve, a duckbill one-way valve, a spring valve, a tension valve, and so forth.

[0032] In a number of embodiments, the shot straw further can include a top cap, such as a threaded lid, a shooter lid, a hinged flip cap, a twist cap, or a squeeze lid, etc., which is configured to removably seal or cover, entirely or partially, the top end of the straw. In some embodiments, the shot straw also can include a bottom cap, such as a quarter-turn threaded cap or silicone end cap, which is configured to removably seal or cover, entirely or partially, the bottom end of the straw. In several embodiments where the shot straw includes at least a straw, a one-way valve, and a top cap for removably sealing the top end of the straw, an inner space can be formed inside the straw between the top cap and the one-way valve and be pre-filled (or re-filled) with a liquid, such as an alcoholic shot (e.g., vodka), medicinal fluid, wellness shot, etc. In certain embodiments, the shot straw can be manufactured and sold with the liquid/shot (e.g., 1-3 fluid ounces (29.57 - 88.72 ml) of alcohol or wellness shot) pre-filled in the inner space, and the top/bottom caps attached at each end. When the shot straw is pre-filled with a shot to be sold off the shelf, the top/bottom opening of the straw body further can be sealed with a film (e.g., a heat induction foil, a lift-and-peel induction liner, etc.) that is covered under the top/bottom cap, and that can be removed before first use.

[0033] In some embodiments, to use the shot straw with a pre-filled shot inside, the top cap and the bottom caps can be opened or removed, and the straw can be placed inside a container (e.g., cup/glass/etc.) that includes a drink, with the bottom end of the straw down in the drink. This one-way valve can prevent the shot from flowing down into the container. The user can suck on the top of the straw, to drink the shot, followed by the drink, as the drink can come up the straw through the one-way valve. In a number of embodiments, the shot straw can be single-use or reusable, and/or can be sold to users at bars, at events with drinks, at liquor stores, wellness shops, etc.

[0034] In a few embodiments, the shot straw additionally can include a second one-way valve or a top one-way valve, placed at or near the top end of the straw. The second or top one-way valve can be configured to allow the shot, the shot-drink mix to flow from the inner space of the straw toward the top end of the straw, but not the other way around, when a user sucks at the top end of the straw. The second one-way valve can be similar to or different from the one-way valve at or near the bottom end of the straw. An exemplary second one-way valve can be a cross-slit one-way valve, a duckbill one-way valve, etc. In some embodiments, the second one-way valve can be coupled to, or constitute part of, the top cap and be inserted into or removed from the straw when the top cap is attached to or detached from the top end of the straw. In similar or different embodiments, the one-way valve can be coupled to, or constitute part of, the bottom cap and be inserted into or removed from the straw when the bottom cap is attached to or detached from the bottom end of the straw.

[0035] In a number of embodiments, the shot straw can include a pintle assembly, in addition to or in lieu of, the one-way valve(s). In embodiments with the pintle assembly, the shot straw can be configured so that when the user sucks from the top of the straw, causing a negative pressure to pull the pintle assembly upward, the openings at or near the top and bottom ends of the straw can open and allow the drink in the cup and/or the shot in the straw to flow toward the top of the straw. In similar and/or different embodiments, the shot straw further can be configured that when the user is not using the straw, the pintle assembly automatically returns to its closed state, in which the openings at or near the top and bottom ends of the straw are sealed and no liquid can come in or out of the straw. In certain embodiments, the pintle assembly can include a pintle head, a spring, a lower valve, a pintle shaft, and/or an upper flow port, etc. The pintle head can be configured to be moved up to open, and moved down to close and seal, an opening at or near the top end of the straw, e.g., an outlet opening of the top cap, depending on whether and how much a suction pressure is applied at the top end of the straw.

[0036] In some embodiments, the spring of the pintle assembly can be configured to hold the pintle assembly in place against the top cap, unless or until a suction pressure exceeding a predetermined pressure is applied from the top end of the straw. The spring further can be configured to withstand the weight of the pintle assembly and/or the liquid in the straw when the straw is upside-down, such as when a user is transporting the shot straw and/or refilling the shot straw from the bottom end of the straw. In a number of embodiments, the spring of the pintle assembly can be made of any suitable materials, such as shape-memory polymers or hard plastics, and can include any suitable structures, such as one or more fingers or a cone extending from the pintle shaft toward the top cap.

[0037] In a number of embodiments, the lower valve of the pintle assembly can be configured to open or close the opening at or near the bottom end of the straw when the pintle assembly is pulled/sucked up by a user or pushed down by the spring of the pintle assembly. In a few embodiments, the lower valve can include one or more outlets that allow the drink in a cup/glass to flow, in an L or a T pattern, through the opening at or near the bottom end into the inner space of the straw. In many embodiments, the lower valve can close the opening at or near the bottom end of the straw by having the lower portion of the pintle shaft move into the opening. The pintle shaft can include a bushing at an exterior surface, at least at the lower portion of the pintle shaft near the lower valve, and the bushing can be configured to protect the exterior surface of the pintle shaft that contacts the opening at or near the bottom end of the straw.

[0038] In some embodiments, the top cap can include a mouthpiece and an outlet opening that is opened or closed by the pintle head of the pintle assembly. The top cap can be configured to be sealed when the pintle head is in, or returns automatically to, its closed state so that the user does not need to open or remove the top cap before using the shot straw. For example, the top cap can be made of a flexible material, or include the flexible material at the outlet opening, so that a seal is formed when the pintle assembly is its closed state. Alternatively or additionally, the pintle head can include an O-ring to seal the outlet opening of the top cap.

[0039] In several embodiments, the bottom cap of the shot straw can include an intake opening that is opened or closed by the pintle assembly. For instance, when the pintle head is in, or returns automatically to, its closed state, the pintle shaft can be configured to stay in the intake opening of the bottom cap while the lower valve is below the intake opening of the bottom cap. When the pintle assembly is lifted upward to its open state, the lower valve can then enter the central opening of the bottom cap, and a fluidic pathway can be formed between the cup/class and the inner space of the straw. The bottom cap further can be configured to be sealed when the pintle assembly is in, or returns automatically to, its closed state so that the user does not need to open or close the bottom cap before or after using the shot straw. For instance, the bottom cap can be made of a flexible material, or include the flexible material (e.g., an O-ring) at the intake opening, so that a seal can be formed when the pintle assembly is its closed state.

[0040] In a number of embodiments, the shot straw can be configured to be refilled from the bottom end of the straw. In some embodiments, the bottom cap can comprise a filler cap and a strainer portion removably coupled to the filler cap. Each of the filler cap and the strainer portion can have a corresponding opening, and their corresponding openings form the intake opening of the bottom cap. When the user is refilling the shot straw, the filler cap can be removed, and the liquid can flow through a strainer of the strainer portion configured to prevent any solid matters in the liquid, such as ice cubes, pulps or clumps in the liquid, etc. When the user is drinking from the shot straw, the filler cap can be closed and seal the strainer portion of the strainer, so that the drink can only flow through the intake opening and/or the lower valve of the pintle assembly. In a few embodiments, the strainer portion further can include a wall configured to support the strainer and detachably engage the filler cap.

[0041] Various embodiments can include a method for providing an apparatus or a shot straw. The apparatus or shot straw, and its components, each can be similar or substantially identical to the apparatus or shot straw, and its corresponding components, in any of the other embodiments described herein. The method can include providing a straw for the apparatus with a straw body. The exterior surface of the straw body can include branding information for promoting the apparatus or the supplier therefor and/or aesthetic designs. In many embodiments, the apparatus and/or its components each can have any suitable dimensions, volumes, and/or materials. The height of the straw can be approximately 9 inches (22.86 cm). The outer diameter of the straw body can be approximately ¼ inch (0.635 cm) to ¾ inch (1.905 cm). The volume of the straw body can be approximately 1 fluid ounce (29.57 ml) to 3 fluid ounces (88.72 ml). The straw body can include clear plastic, thermoplastic, or any other suitable materials.

[0042] The method further can include coupling a one-way valve for the apparatus at a bottom end of the straw. The bottom end of the straw can be configured to be placed in a container. When placed in the container, the one-way valve can be configured to allow liquid (e.g., water, soda, juice, etc.) in the container to enter the straw when a suction force is created at a top end of the straw, the top end opposite the bottom end of the straw. In some embodiments, the one-way valve can include one of: a cross-slit valve, a duckbill valve, a spring valve, a tension valve, or any other suitable one-way valves.

[0043] In some embodiments, the method further can include one or more of: (a) removably coupling a top cap to the top end of the straw; (b) removably coupling a bottom cap to the one way valve to seal the one-way valve; (c) sealing the top end of the straw by a removable film; and/or (d) filling a second liquid (e.g., an alcohol shot) into the straw body. The top cap can include one of: a threaded lid, a shooter lid, a hinged flip cap, a twist cap, a squeeze lid, or any other suitable caps. In certain embodiments, the top cap additionally can include a top one-way valve configured to allow the second liquid in the straw to exit the straw from the top end when the suction force is created at the top end of the straw. The top one-way valve further can include one of: a cross-slit valve, a duckbill valve, a spring valve, a tension valve, or any other suitable one-way valves. In several embodiments, the bottom cap can include a quarter-turn threaded cap, an end cap, or any other suitable caps. The bottom cap also can be configured to seal the one-way valve by any suitable components, e.g., a lid.

[0044] Various embodiments can include a method for using an apparatus or a shot straw. The method can include placing the apparatus into a container, with a bottom end of the apparatus submerged in a first liquid in the container. The apparatus can include a straw and a one-way valve. The apparatus, and/or its components (e.g., the straw and/or the one-way valve), each can be similar or substantially identical to the apparatus or shot straw, and/or its corresponding components, in any of the other embodiments described herein. The apparatus and/or its components each also can have any suitable dimensions, configurations, volumes, and/or materials. For example, the apparatus can have a height of approximately 9 inches (22.86 cm), an outer diameter of approximately ¼ inch (0.635 cm) to ¾ inch (1.905 cm), and/or a volume of approximately 1 fluid ounce (29.57 ml) to 3 fluid ounces (88.72 ml).

[0045] In a number of embodiments, the straw can include a top end, a straw body, and the bottom end opposite the top end. The straw body can include clear plastic, thermoplastic, or any other suitable materials. An exterior surface of the straw body can include any suitable branding information and/or aesthetic designs. The one-way valve can be removably coupled to the bottom end of the straw. The one-way valve can include one of: a cross-slit valve, a duckbill valve, a spring valve, a tension valve, or any other suitable one-way valves.

[0046] In some embodiments, the apparatus further can include: (a) a top cap removably coupled to the top end of the straw; (b) a bottom cap removably coupled to the one-way valve and configured to seal the one-way valve; and/or (c) a film configured to removably seal the top end of the straw. The top cap further can include one of: a threaded lid, a shooter lid, a hinged flip cap, a twist cap, a squeeze lid, or any other suitable caps. In several embodiments, the top cap further can include a top one-way valve configured to allow a second liquid in the straw to exit the straw from the top end when a suction force is created at the top end of the straw. The top one-way valve can comprise one of: a cross-slit valve, a duckbill valve, a spring valve, a tension valve, or any other suitable one-way valves. The bottom cap further can include a quarter-turn threaded cap, an end cap, or any other suitable caps. The bottom cap also can be configured to seal the one-way valve by any suitable components, e.g., a lid. The second liquid can be filled into the straw from the top end or the bottom end.

[0047] In many embodiments, the method further can include drinking the first liquid and the second liquid in the straw from the apparatus by sucking at the top end of the straw. Drinking the first liquid and the second liquid in the straw from the apparatus further can include opening the top cap and/or the bottom cap, if any. In embodiments where the apparatus includes the film, drinking the first liquid and the second liquid in the straw from the apparatus further can include removing the film.

[0048] Turning to the drawings, FIG. 1 illustrates a shot straw (1), according to an embodiment. The shot straw (1) can include a straw (110), a one-way valve (120, not shown), a bottom cap (130), and a top cap (140). The shot straw (1), and/or its components (e.g., the straw (110), the one-way valve (120), etc.), each can be similar or substantially identical to the shot straw and/or the apparatus, and/or their corresponding components, in any of the other embodiments described herein. The straw (110) is made of rigid clear plastic and includes a label (111) printed on or glued to the exterior surface of the straw (110). The one-way valve (120) here is hidden inside the bottom cap (130). Before using the shot straw (1), a user can open the top cap (140) and pour a shot (e.g., 1-3 fluid ounces (29.57 - 88.72 ml) of liquor, wellness drink, etc.) from atop opening into the straw (110). If the user is not using the shot straw (1) right away, the user can put the bottom cap (130) and the top cap (140) back on to seal the straw (110) and carry the shot straw (1) with the user.

[0049] Continuing with FIG. 1, when the user is about to use the shot straw (1), the user can open the bottom cap (130) and the top cap (140) and drink from the straw (110) containing the shot after placing the bottom end of the straw (110) in a drink and sucking at the top end of the straw (110). By sucking at the top end of the straw (110), the user causes a decreased fluid pressure in the straw (110) which results in an imbalance between the pressures inside and outside the straw (110). Once the difference between the pressures inside and outside the straw (110) reaches a predetermined level, the one-way valve (120) can be pushed open to allow the drink to enter the straw (110) and flow upward with the shot toward the top end of the straw (110) to the user's mouth, and the user can then enjoy the shot and/or the mix of the shot and the drink. When the user stops sucking, the difference between the pressures inside and outside the straw (110) drops immediately. Once the difference is below the predetermined level, the one-way valve (120) would return to its closed state and prevent the liquid inside the straw (110), including the shot and/or the drink, from flowing out of the straw (110) due to gravity.

[0050] Turning ahead in the drawings, FIG. 2 illustrates another shot straw (2), according to an embodiment. The shot straw (2) can include a straw (210), a one-way valve (220), a bottom cap (230), and a top cap (240). The shot straw (2), and/or its components, each can be similar or substantially identical to the shot straw and/or the apparatus, and/or their corresponding components, in any of the other embodiments described herein (e.g., the shot straw (1) (FIG. 1)). The straw (210) is made of food-grade clear thermoplastic and has a company logo (211) printed on or glued to the exterior surface of the straw (210). The one-way valve (220) can be similar or identical to the one-way valve (120) (FIG. 1) and to be coupled to the straw (210) at or near the bottom end of the straw (210). The bottom cap (230) here is a quarter turn release cap removably inserted in the bottom end of the straw (210). In this or another embodiment, the one-way valve (220) can be held by the bottom cap (230) and be inserted into the straw (210) together with the bottom cap (230). The top cap (240) here can be a threaded lid.

[0051] Turning ahead in the drawings, FIGs. 3-4 illustrate an exemplary shot straw (3), according to an embodiment. The shot straw (3) can include a straw (310), a bottom one-way valve (320), a bottom cap (330), a top cap (340), and a top one-way valve assembly (350). The shot straw (3), and/or its components, each can be similar or substantially identical to the shot straw and/or the apparatus, and/or their corresponding components, in any of the other embodiments described herein (e.g., the shot straw (1-2) (FIGs. 1-2)). The straw (310) is cylindrical and has a 9-inch (22.86-cm) height and a half-inch (1.27-cm) outer diameter. The bottom one-way valve (320) here is a cross-slit one-way valve to be held at or near the bottom end of the straw (310), inside the bottom cap (330). The top cap (340) is a Hipped-open cap and comprises a top portion (341) and a bottom portion (342). The top portion (341) is hingedly coupled to the bottom portion (342) and is configured to be flipped opened or closed by a rotational movement with a limited rotational angle. The top portion (341) has a lip (343) protruding from an exterior surface at or near the bottom edge of the top portion (341) to allow a user to push the top portion (341) open. The bottom portion (342) of the top cap (340) is configured to be coupled to the top end of the straw (310). The bottom portion (342) is further configured to hold the top one-way valve assembly (350) inside the top cap (340). The top one-way valve assembly (350) includes a cross-slit one-way valve (351) and a support (352) configured to hold the cross-slit one way valve (351) in place inside the top cap (340) when the top cap (340) is coupled to the straw (310). In similar or different embodiments, the top one-way valve assembly (350) can be configured so that the top one-way valve assembly (350) can be removed with the top cap (340). In similar or alternate embodiments, the top one-way valve assembly (350) can be configured so that the top one-way valve assembly (350) can remain coupled to the straw (310) when the top cap (340) is removed from the straw (310).

[0052] Continuing with FIGs. 3-4, once the shot straw (3) is assembled, the bottom one-way valve (320) and the top one-way valve assembly (350) are properly arranged so that when in use, any liquid flows in the straw (310) is allowed to move in a single direction (e.g., the direction pointed by the arrow (X)). When in use, the shot straw (3) can be pre-filled with any liquid (e.g., alcohol, a wellness shot, or any liquid with supplements or medicines, etc.) inside an inner space of the straw (310), between the bottom one-way valve (320) and the top one-way valve assembly (350). After the bottom cap (330) and the top cap (340) are opened, the shot straw (3) can be placed into a container (e.g., a glass or cup), with the bottom portion of the straw (310) entering the container first. When the container contains a drink (e.g., a juice, alcohol, or beverage, etc.) and a user sucks from the top end of the straw (310), the drink will be drawn into the straw (310), through the bottom one-way valve (320), flow upward with the shot, and finally pass through the top one-way valve assembly (350) into the user's mouth. In contrast, if the user places the shot straw (3) upside-down in the container, the user would not be able to drink the shot or the drink from the bottom end of the straw (310) because the bottom one-way valve (320) and the top one way valve assembly (350) are configured to prevent the shot and the drink from flowing in the wrong direction.

The straw (1010) can be made of rigid clear plastic, thermoplastic, or any suitable materials. The pintle assembly (1020) comprises a pintle head (1021), a spring (1022), a lower valve (1023), a pintle shaft (1024), and an upper support (1025). The pintle head (1021) is configured to seal an outlet opening (1042) of the top cap (1040) and prevent the shot or any liquid in the straw (1010) from flowing out of the outlet opening (1042) when the pintle head (1021) is in a closed state. The spring (1022) can be configured to maintain a down pressure to keep the pintle assembly (1020) in its closed state. The spring (1022) can be implemented in any suitable structure and made of any suitable materials. For instance, the spring (1022) in FIGs. 10-12 can include multiple fingers made of flexible materials, such as shape- memory polymers (e.g., PET), and extending upward from the pintle shaft (1024) against the top cap (1040). In some embodiments, each of the entire pintle assembly (1020), the bottom cap (1030), and/or the top cap (1040) can be made of one or more of any suitable materials, including shape-memory polymers.

[0059] The bottom cap (1030) in FIGs. 10-12 can include a filler cap (1031), a strainer cap (1032), and an intake opening (1033). The filler cap (1031) and the strainer cap (1032) can be removably coupled so that the provider or user can fill or refill the shot straw by pouring the liquid through the strainer cap (1032) to remove unwanted solid materials, such as ice cubes, pulps, or clumps, etc. The filler cap (1031) further can be configured to close and seal the strainer cap (1032) by being snugly coupled to the strainer cap (1032).

An exemplary spring valve (e.g., the spring valve (37) (FIGs. 37-38)) can include a spring to keep the valve shut by default and allow a suction pressure exceeding a predetermined pressure limit to force the valve to open against the spring-loading.

[0073] Further, in various embodiments, an exemplary tension valve (e.g., the tension valve (39, 40, 42, or 45) (FIGs. 39-48)) can be implemented in any suitable ways. In some embodiments, a tension valve can include one or more slits on a curving thin film or plate made of any suitable elastomers (e.g., rubber or silicone) and be configured to open or close the slit(s) in a single direction depending on the extent of deformation that the pressure causes on the curving film or plate (see, e.g., the x-slit one-way valve (220) (FIG. 2), (350) (FIGS. 3-4), (820) (FIG. 8), (2631) (FIGs. 26-28), (2931) (FIGs. 29-30), (3131) (FIGs. 31-36) or (39) (FIG. 39)). In similar or different embodiments, a tension valve can include a sealing plug made of any suitable elastomers (e.g., rubber or silicone) (e.g., the tension valve 4210 (FIGs. 42-44), or 4510 (FIGs. 45-48)), and a base (e.g., the base 4220 (FIGs. 42-44) or 4520 (FIGs. 45-48) configured to couple the tension valve with the straw of a shot straw (e.g., the shot straw (1-3) (FIGs. 1-4), (5) (FIGs. 5-6), (26) (FIGs. 26-28), (29) (FIGs. 29-30), or (31) (FIGs. 31-36)). The sealing plug can be configured to be engage with the base and seal one or more holes (e.g., the holes of the strainer (3134) (FIG. 36) or the holes 4521 (FIG. 45)) in the base. When the exemplary tension valve is used as the bottom cap of a shot straw, and a suction force comes from the top end of the shot straw, the sealing plug can be deformed to the extent that the sealing plug can no longer seal the one or more holes and the liquid in a cup that the shot straw is placed in can be flow through the one or more holes into the shot straw. Once the suction force is lower than a predetermined threshold, the sealing plug can return to its original shape and dimension, and the holes are then sealed again.

[0074] In a number of embodiments, a duckbill one-way valve (e.g., the duckbill valve (920 and/or 920') (FIG. 9), or (49, 52-54, or 56) (FIGs. -49-56)) can be used at the top cap or bottom cap of a shot straw (e.g., the shot straw (1-3) (FIGs. 1-4), (5) (FIGs. 5-6), (26) (FIGs. 26-28), (29) (FIGs. 29-30), or (31) (FIGs. -31-36)). An exemplary one-way valve can include two or more flat-ended flaps (see, e.g., the flat-end flap (923 and/or 923') (FIG. 9) or (4910 and/or 4920) (FIGs. 49-51)), and can be configured to open and close at the flat ends of the flat-ended flaps in response to a suction force applied. In several embodiments, the one-way valve(s) used in a shot straw can be properly configured in terms of quantity, type, dimension, material, and/or shape, etc. so that the shot straw is easy to use while the shot (e.g., an alcoholic shot or a wellness shot) does not leak from the straw. For example, a shot straw with a single one-way valve at the bottom cap can be easier to use than another shot straw with a similar one-way valve at the bottom cap and another similar one-way valve at the top cap because the suction force required to use the one-way valves at the top cap and the bottom cap can be greater than that for the single one-way valve. In another example, a shot straw with an x-slit one-way valve can be easier to use compared to another shot straw including a tension valve with a rubber seal plug, while the latter can work better in terms of leak proof.
