Abstract
Description
Technical Field
[0001] This utility model relates to the field of straw technology, specifically to a U-shaped paper straw anti-scalding structure. Background Technology
[0002] In daily life, various beverages such as water and liquid milk need to be heated before consumption, especially during certain seasons or for specific groups of people. If the temperature of a heated beverage exceeds 45 degrees Celsius when inhaled through a straw, it can cause a scalding sensation in the mouth. Temperatures reaching 50 degrees Celsius can cause blister-like burns. Existing paper straws are either cylindrical or have a simple U-shaped structure and lack a dedicated anti-scalding design. Once inserted into a hot drink, the high temperature is quickly conducted to the sucking end, causing burns to the user's mouth from the hot liquid.
[0003] Based on the above, this utility model proposes a U-shaped paper straw anti-scalding structure, which can effectively solve the above problems. Utility Model Content
[0004] This utility model addresses the shortcomings of the existing technology by providing a U-shaped paper straw anti-scalding structure.
[0005] This utility model is achieved through the following technical solution: A U-shaped paper straw anti-scalding structure includes a straw body, which comprises a sucking section, a telescopic bending section, and an insertion section connected in sequence. The telescopic bending section has a corrugated tube structure. A plastic film is glued to one end of the sucking section and the insertion section near the telescopic bending section with food-grade adhesive. A through hole for liquid to pass through is opened in the middle of the plastic film. The diameter of the through hole is 1 / 2 of the diameter of the straw body.
[0006] According to the above technical solution, as a further preferred technical solution, the straw body is made of three layers of biodegradable paper spirally wound together, and the three layers of biodegradable paper are bonded together with food-grade adhesive.
[0007] According to the above technical solution, as a further preferred technical solution, the biodegradable paper material is kraft paper.
[0008] According to the above technical solution, as a further preferred technical solution, the bottom of the insertion segment is provided with a pointed portion.
[0009] According to the above technical solution, as a further preferred technical solution, the inner and outer surfaces of the straw are covered with a waterproof coating layer.
[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model provides a U-shaped paper straw anti-scalding structure. By adopting a corrugated tube structure with a telescopic bending section, the straight-line distance between the sucking section and the insertion section can be shortened through the bending shape, preventing the heat of high-temperature liquid from being rapidly conducted to the sucking end. Furthermore, by placing a plastic film at one end of the sucking section and the insertion section near the telescopic bending section, and the diameter of the through hole in the middle of the plastic film is 1 / 2 the diameter of the straw body, the outflow speed and single outflow volume of high-temperature liquid can be limited without affecting normal sucking. This allows the slowly flowing liquid to have more time to contact the air and cool down, improving the anti-scalding effect. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a cross-sectional structural diagram of the present invention; Figure 3 This is a schematic diagram of the plastic film structure of this utility model. Detailed Implementation
[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.
[0013] A U-shaped paper straw anti-scalding structure includes a straw body, which comprises a sucking section 1, a telescopic bending section 2, and an insertion section 3 connected in sequence. The telescopic bending section 2 has a corrugated tube structure. A plastic film 4 is glued to one end of the sucking section 1 and the insertion section 3 near the telescopic bending section 2 by food-grade adhesive. A through hole 5 for liquid to pass through is opened in the middle of the plastic film 4. The diameter of the through hole 5 is 1 / 2 of the diameter of the straw body.
[0014] This invention employs a corrugated tube structure with a telescopic bending section, which shortens the straight-line distance between the suction section and the insertion section through the bending shape, preventing the rapid conduction of heat from the high-temperature liquid to the suction end. Furthermore, by placing a plastic film 4 at one end of the suction section 1 and the insertion section 3 near the telescopic bending section 2, and with the diameter of the through hole 5 in the middle of the plastic film being 1 / 2 the diameter of the straw body, the outflow speed and single outflow volume of the high-temperature liquid can be limited without affecting normal suction, allowing the slowly flowing liquid to have more time to contact the air and cool down, thus improving the anti-scalding effect.
[0015] Furthermore, in another embodiment, the straw body is made of three layers of biodegradable paper material 6 spirally wound together, and the three layers of biodegradable paper material 6 are bonded together with food-grade adhesive.
[0016] Furthermore, in another embodiment, the biodegradable paper material 6 is kraft paper.
[0017] Furthermore, in another embodiment, the bottom of the insertion segment 3 is provided with a tip 7.
[0018] The tip 7 facilitates precise penetration of the sealing film.
[0019] Furthermore, in another embodiment, both the inner and outer surfaces of the straw are covered with a waterproof coating layer 8.
[0020] By setting a waterproof coating layer 8, the waterproof coating layer can prevent the liquid in the beverage from directly contacting the paper material, avoid the paper material from absorbing water and softening, and reduce the decrease in structural strength of the straw due to water absorption by the outer layer.
[0021] Based on the description and drawings of this utility model, those skilled in the art can easily manufacture or use the U-shaped paper straw anti-scalding structure of this utility model, and can produce the positive effects described in this utility model.
[0022] Unless otherwise specified, in this utility model, terms such as "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe orientation or positional relationships in this utility model are for illustrative purposes only and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood in conjunction with the accompanying drawings and according to the specific circumstances.
[0023] Unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
