Description

Technical Field

[0001] This utility model relates to the field of straw technology, specifically a straw that can add additives to beverages. Background Technology

[0002] In existing probiotic drinks, probiotics are added directly to the beverage during production and processing. However, the drinks undergo sterilization before leaving the factory, which kills harmful bacteria and causes a large number of probiotics to become inactive. Therefore, there is a need for a tool that can add beneficial bacteria to the beverage just before consumption.

[0003] Instant beverages, cold brew tea, and other drinks also require the use of special additive-adding tools (such as bottle caps) to add the corresponding additives to the bottle before consumption. However, this method is only applicable to bottled beverages and is not suitable for bagged or boxed beverages (such as yogurt).

[0004] The existing technology, represented by Chinese patent CN2891881Y, a milk straw with dual functions, involves filling or coating the straw with additives such as live bacteria. When using the straw, it is inserted into the beverage, and the live bacteria and other additives are inhaled along with the beverage.

[0005] This method can lead to uneven concentration of additives in the drink. In the early stages, due to the large amount of additives present, the concentration of probiotics or seasonings consumed with the drink is too high. Excessive probiotic content can cause gastrointestinal discomfort and immune system imbalance, while excessive seasoning concentration can lead to poor taste. As the drink continues to carry additives, the concentration of additives in the straw decreases, resulting in a continuous reduction in the amount of additives consumed. If the additive is a seasoning, the taste may be too strong in the early stages and bland in the later stages. Utility Model Content

[0006] The technical problem to be solved by this invention is to overcome the existing defects and provide a straw that can add additives to beverages, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model discloses a straw capable of adding additives to beverages. The technical solution includes an outer tube and an inner tube, with the inner tube slidably connected within the outer tube to form a telescopic tube structure. The inner tube has a first sealing element and a second sealing element at both ends, and contains solvent. The first and second sealing elements prevent solvent leakage during transportation. The first sealing element can be a cap or a sealing film; the second sealing element can be a sealing film or a partition. A manually operated communication structure connects the inner and outer tubes. The outer tube contains a solute chamber located below the manually operated communication structure, containing the additive. A third sealing element is located at the bottom of the solute chamber and connected to the outer tube. The second sealing element can be opened via the manually operated communication structure, allowing the solvent to enter the solute chamber to dissolve the additive, which then passes through the third sealing element into the beverage. After mixing evenly with the beverage, the additive concentration in the mouth will be more uniform. The additive in the solute chamber can be probiotic freeze-dried powder, seasoning, tea, etc., and the solvent can be physiological saline, purified water, etc.

[0008] As a preferred embodiment of this invention, a positioning element is provided between the outer tube and the outer wall of the inner tube. This positioning element prevents accidental slippage between the inner and outer tubes during transportation, thus preventing accidental damage to the second sealing element. The positioning element can be made of tape, buckles, or the like.

[0009] As a preferred technical solution of this utility model, the third sealing element is a water-soluble film, such as a polyvinyl alcohol (PVA) water-soluble film. After the solvent comes into contact with it, the water-soluble film can be dissolved, and the solution containing the dissolved additives can be added to the beverage below. The polyvinyl alcohol used is food grade.

[0010] In a preferred embodiment of this invention, the second sealing element is a sealing film attached to the bottom surface of the inner tube. The sealing film is a composite film consisting of an outer layer of polyethylene terephthalate (PET) film, a middle layer of aluminum foil, and an inner layer of polyethylene (PE) film.

[0011] In a preferred embodiment of this invention, the manual connection structure is an extension portion connected to the second sealing member and attached to the inner wall of the outer tube. The adhesion strength between the extension portion and the inner wall of the outer tube is greater than the adhesion strength between the second sealing member and the bottom surface of the inner tube. During the process of stretching the straw, the outer tube tears the film of the second sealing member from the bottom surface of the inner tube through the extension portion, thereby connecting the inner tube with the solute chamber of the inner tube and allowing the solvent to flow out.

[0012] In a preferred embodiment of this invention, the inner tube is open at the top and has a bottom section with multiple liquid passage holes. The second sealing member is located on the bottom section and includes a sealing portion below the liquid passage holes. Multiple sealing portions correspond one-to-one with each liquid passage hole and are connected together. This structure prevents the second sealing member from obstructing the upward flow of beverages during drinking due to its large coverage area after removal, thus ensuring usability.

[0013] In a preferred embodiment of this invention, the additive is filled in the solute chamber or adhered to the inner wall of the solute chamber. Adherence to the inner wall allows for smoother solvent flow, a larger contact area with the additive, and more complete and rapid dissolution.

[0014] In a preferred embodiment of this invention, the solute chamber further includes a support plate with flow holes and a support element or support surface. The additive adheres to the support element or support surface. The support element increases the adhesion area of ​​the additive, thereby ensuring the fluidity of the solvent while increasing the amount of additive it can carry and further expanding the contact area.

[0015] In a preferred embodiment of this invention, the manual connection structure is a piercing element located on the support plate, opposite to the second sealing element. In use, the straw can be shortened further to allow the piercing element to pierce the second sealing element, and then the straw can be lengthened.

[0016] As a preferred embodiment of this invention, the inner wall of the outer tube has a limiting groove and a connecting groove, the limiting groove and the connecting groove being connected. The inner tube has a limiting block, which slides in contact with the limiting groove and the connecting groove. When the limiting block is in the limiting groove, it restricts the extension and retraction of the outer tube and the inner tube. When the telescopic limiting block is in the connecting groove, it allows for the extension and retraction of the outer tube and the inner tube. This structure prevents the piercing element from puncturing the second sealing element during transportation.

[0017] Compared with existing technologies, the advantages of this invention are as follows: This invention stores solvent in the inner tube and solute in the outer tube. In use, the straw is inserted into the beverage packaging and pulled out (or pulled out first and then inserted). During the straw's extension, the second closure opens, allowing the solvent to enter the outer tube, dissolving the additives and further dissolving the third closure. After the third closure is dissolved, the additive solution enters the beverage. After shaking evenly, a relatively uniform concentration of the beverage and additive mixture can be consumed. Furthermore, using a straw as a carrier, it can be adapted to various different beverage packaging, offering strong versatility. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1

[0042] like Figures 1 to 2 As shown, this embodiment discloses the first implementation of the present invention. The technical solution adopted includes an outer tube 1 and an inner tube 2, wherein the inner tube 2 is slidably connected within the outer tube 1, as shown. Figure 2 As shown, a slide 101 is opened on the inner wall of the outer tube 1. The slide 101 is longitudinal. A limiting ring 201 is on the outer wall of the inner tube 2. The limiting ring 201 slides in the slide 101. Both ends of the slide 101 are not connected to the end face of the outer tube 1, so the inner tube 2 will not come out of the outer tube 1.

[0043] There is a solute chamber inside the outer tube 1, which is located below the inner tube 2. The solute chamber is filled with additive 5, which is probiotic freeze-dried powder. The bottom of the solute chamber is sealed with a third sealing element 8 to prevent the additive 5 from leaking out. In order to add the additive 5 evenly into the beverage, a solvent 4, which is physiological saline, is stored in the inner tube 2. In order to prevent the physiological saline from coming into premature contact with the probiotic freeze-dried powder during storage and transportation, which would lead to premature activation of the probiotics without the user's consent, a sealing film is attached to the lower end of the inner tube 2 as a second sealing element 7. The sealing film is a composite film with an outer layer of polyethylene terephthalate (PET) film, a middle layer of aluminum foil, and an inner layer of polyethylene (PE) film. An external thread is processed on the upper outer wall of the inner tube 2, and a cap is connected as a first sealing element 3. The cap has an internal thread that engages with the external thread of the inner tube 2.

[0044] In order to allow physiological saline to enter the solute chamber during use, such as Figure 2 As shown, one end of the second sealing member 7 is connected to an extension 701 as a manual communication structure. The extension 701 is a film layer that is vertically downward perpendicular to the sealing film. Its strength is higher than the sealing film strength of the second sealing member 7. The extension 701 adheres to the inner wall of the outer tube 1, and the adhesion strength between the extension 701 and the outer tube 1 is higher than the adhesion strength between the second sealing member 7 and the bottom surface of the inner tube 2.

[0045] When drinking, in order to allow the probiotic freeze-dried powder to enter the beverage after being dissolved in physiological saline, the third sealing component 8 is made of food-grade polyvinyl alcohol water-soluble membrane.

[0046] To prevent relative sliding between the outer tube 1 and the inner tube 2 during storage and transportation, the length of the straw packaging bag should not differ too much from the length of the straw itself during storage and transportation. The length of the straw packaging bag is used to constrain the straw's contracted state.

[0047] The working principle of this utility model:

[0048] Tear open the straw packaging bag and take out the straw. Keep the upper end of the inner tube 2 of the straw vertically upward. Twist off the first sealing member 3. Hold the outer tube 1 and the inner tube 2 with both hands respectively and pull downward to extend. The limiting ring 201 slides in the slide 101. During the downward movement of the outer tube 1, the extension 701 pulls the second sealing member 7, causing it to peel off from the inner tube 2. The saline in the inner tube 2 enters the solute chamber of the outer tube 1, dissolves the probiotic freeze-dried powder, and contacts the third sealing member 8 downward. Insert the straw into the yogurt packaging. The water and saline in the yogurt dissolve the third sealing member 8 from both sides simultaneously. After the third sealing member 8 dissolves, the probiotic solution enters the yogurt.

[0049] Users can also increase the pressure on the third seal 8 by blowing air into the straw after inserting it into the yogurt packaging, thereby accelerating its rupture. At the same time, they can check whether the third seal 8 is damaged by the smoothness of blowing air. After ensuring that it is damaged, the lower end of the straw is immersed in the yogurt, and the straw is rotated to stir the yogurt before drinking.

[0050] Example 2

[0051] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the first sealing member 3 is a sealing film, and its material is the same as that of the second sealing member 7; in order to prevent the straw from stretching accidentally during the storage and transportation of the straw, a positioning member 6 is provided between the outer wall of the outer tube 1 and the outer wall of the inner tube 2, and the positioning member 6 is made of BOPP tape.

[0052] Due to the use of positioning component 6, the length difference between the packaging bag of the straw and the length of the straw itself during storage and transportation does not need to be strictly limited.

[0053] When using, after removing the straw from the packaging bag, keep the upper end of the inner tube 2 of the straw vertically upward, tear off the first sealing piece 3 and the positioning piece 6, and then stretch the straw. The rest of the operation is the same as in Example 1.

[0054] Example 3

[0055] like Figure 4 As shown, the difference between this embodiment and Embodiment 2 is that the extension 701 is connected to the second closure 7 via a traction strap 704, so as to... Figure 4 Based on the shown perspective, the connection point between the traction strap 704 and the second closure 7 is located at the right edge of the second closure 7, and the extension 701 is located below the left edge of the second closure 7. This structure allows the traction strap 704 to apply a downward force to the second closure 7 when the straw is stretched. Furthermore, as the second closure 7 is peeled from the bottom surface of the inner tube 2, the direction of the force applied by the traction strap 704 to the second closure 7 gradually shifts to vertical, thus facilitating the peeling of the second closure 7.

[0056] Example 4

[0057] like Figure 5 , Figure 6 As shown, the difference between this embodiment and embodiment 1 is that a fourth sealing member 10 is provided between the first sealing member 3 and the upper end face of the inner tube 2. The fourth sealing member 10 is a sealing film of the same material as the second sealing member 7, thereby improving the sealing performance of the upper port of the inner tube 2, and the cover can protect the sealing film.

[0058] The probiotic freeze-dried powder is attached to the carrier 9, which is a powder carrier ball. The carrier 9 is filled in the solute chamber. There are large gaps between the carriers 9, which allows the physiological saline to flow downward more smoothly.

[0059] During use, first remove the straw from the packaging bag, keep the upper end of the inner tube 2 of the straw vertically upward, twist to remove the first sealing piece 3, tear off the fourth sealing piece 10, and then stretch the straw. The remaining operations are the same as in Example 1.

[0060] Example 5

[0061] like Figures 7 to 10 As shown, the difference between this embodiment and embodiment 2 is that the lower end of the inner tube 2 has a tube bottom 202, and the inner tube 2 is connected to the solute chamber of the outer tube 1 through a liquid passage hole 203 provided on the tube bottom 202. There are three liquid passage holes 203. The second sealing member 7 includes three sealing parts 702, which are respectively adhered to the three liquid passage holes 203. One sealing part 702 is connected to the extension part 701, and the other two sealing parts 702 are connected to the sealing part 702 connected to the extension part 701 through the connecting part 703.

[0062] In the solute chamber, additive 5 is a seasoning that adheres to the inner wall of the outer tube 1, while solvent 4 in the inner tube 2 is water.

[0063] In use, after removing the straw from the packaging bag, keep the upper end of the inner tube 2 of the straw vertically upward, tear off the first sealing part 3 and the positioning part 6, and then stretch the straw. When stretching, the outer tube 1 pulls the connected sealing part 702 from the bottom 202 of the tube through the extension part 701. At the same time, the connecting part 703 drives the other two sealing parts 702 to peel off from the bottom 202 of the tube, thereby opening the liquid passage 203. Water leaks from the liquid passage 203 into the solute chamber to dissolve the seasoning on the inner wall of the outer tube 1 and quickly and fully contact the third sealing part 8. Insert the straw into the beverage bottle. After inserting the straw into the beverage bottle, you can blow air into the straw to increase the pressure on the third sealing part 8, thereby accelerating its breakage. At the same time, you can check whether the third sealing part 8 is broken by the smoothness of blowing air. After ensuring that it is broken, rotate the straw to stir the beverage before drinking. The remaining operations are the same as in Example 1.

[0064] This embodiment can prevent the coverage area of ​​the second sealing member 7 from being too large. During the drinking process, the second sealing member 7 may cause blockage of the outer tube 1 due to the influence of air pressure or the flow of the beverage, thus affecting the drinking experience.

[0065] Example 6

[0066] like Figure 11As shown, the difference between this embodiment and Embodiment 5 is that the extension 701 is connected to a closing portion 702 of the second closing member 7 via a traction strap 704. The traction strap 704 is connected to one edge of the second closing member 7, and the extension 701 is located below the other edge of the second closing member 7. With this structure, when the straw is stretched, the traction strap 704 can apply a downward force to the closing portion 702. As the closing portion 702 is peeled off from the bottom 202 of the straw, the direction of the force applied by the traction strap 704 to the second closing member 7 gradually turns vertical, thus facilitating the peeling of the closing portion 702.

[0067] Example 7

[0068] like Figure 12 , Figure 13 As shown, the difference between this embodiment and embodiment 5 is that a support plate 11 is also provided in the solute chamber. The support plate 11 is a mesh plate connected to the inner wall of the outer tube 1. The mesh on the support plate 11 is a flow hole. Multiple support members 12 are connected below the support plate 11. The support members 12 are rod-shaped structures and are vertically arranged. Seasonings are also attached to their surfaces.

[0069] The arrangement of the carrier 12 increases the load capacity of the seasoning without affecting the flow of water and beverage.

[0070] When in use, after opening the sealing part 702, the water flows down through the liquid passage 203, passes through the flow passage of the support plate 11 and enters the solute chamber, dissolving the seasonings attached to the inner wall of the outer tube 1 and the support plate 11.

[0071] Example 8

[0072] like Figure 14 As shown, the difference between this embodiment and embodiment 7 is that the carrier 12 is a tubular structure, and its opening corresponds to the position of the flow hole.

[0073] This embodiment can further increase the capacity of seasonings.

[0074] Example 9

[0075] like Figures 15 to 21 As shown, the difference between this embodiment and embodiment 7 is that the manual connection structure is a cone-shaped piercing member 13, with the piercing member 13 facing the second sealing member 7. In order for the piercing member 13 to pierce the second sealing member 7, as... Figure 16As shown, during storage and transportation, the slide 101 provides space for further shortening of the straw. However, to prevent the piercing element 13 from piercing the second sealing element 7 during storage and transportation, a horizontal limiting groove 102 and a vertical connecting groove 103 are formed on the inner wall of the outer tube 1. The lower end of the connecting groove 103 is connected to the slide 101, and the limiting groove 102 and the connecting groove 103 are connected and form a T-shaped structure. A limiting block 204 is provided on the outer wall of the inner tube 2. The limiting block 204 is slidably connected in the limiting groove 102 and the connecting groove 103. During storage and transportation, the limiting block 204 is located in the limiting groove 102. The limiting block 204 and the positioning element 6 form a double safety measure to ensure safety during storage and transportation.

[0076] In use, when the straw needs to be extended or retracted, first remove the positioning piece 6. Hold the outer tube 1 and inner tube 2 with both hands respectively, and twist the inner tube 2 to screw the limiting block 204 from the limiting groove 102 into the connecting groove 103. Then, in the vertical direction, further shorten the straw. The limiting block 204 slides along the connecting groove 103, and the piercing piece 13 pierces the second sealing piece 7. The water in the inner tube 2 enters the solute chamber. Then, vertically extend the straw, and the limiting block 204 enters the slide 101 from the connecting groove 103. Other operating steps are the same as in Example 7.

[0077] The mechanical connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It is common knowledge.

[0078] The BOPP tape, the composite sealing film of the second sealing element 7, the polyvinyl alcohol water-soluble film, the powder carrier ball, and other components and compositions not described in detail herein are all prior art.

[0079] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
