Definitions

  • the present invention relates to a drinking straw, and more particularly to a drinking straw that can be cleaned easily, can reduce the cost of manufacture, and can improve suction efficiency.
  • the conventional eco-friendly drinking straws are mainly made of tubular structures made of hard materials such as stainless steel and plastic, and consumers can clean an inner part of the conventional eco-friendly drinking straw by using a brush that can be inserted into the inner part of the conventional eco-friendly drinking straw after use, so that the conventional eco-friendly drinking straw can be reused.
  • a conventional drinking straw in order to clean the inner part of the conventional eco-friendly drinking straw, a conventional drinking straw is provided and has two arcuate walls engaged with each other and a connecting portion disposed between the two arcuate walls.
  • the two arcuate walls are made of a hard material and the connecting portion is made of plastic. Consumers can clean the inner part of the conventional drinking straw by disengaging the two hard arcuate walls.
  • the two hard arcuate walls and the plastic connection portion are connected with each other of dissimilar materials. In the process of connecting, over-molding or injection molding is required, and the manufacturing method is more complicated and the equipment cost of the forming molds is also higher.
  • the present invention provides a drinking straw to mitigate or obviate the aforementioned problems.
  • the main objective of the present invention is to provide a drinking straw that can be cleaned easily, can reduce the cost of manufacture, and can improve suction efficiency.
  • the drinking straw in accordance with the present invention is integrally formed of a food-grade plastic material, is flexible and comprises a sheet body, a first engaging portion, and a second engaging portion.
  • the first engaging portion and the second engaging portion are respectively formed on two side edges of the sheet body, and the sheet body can be wound into a tubular shape to enable the first engaging portion to engage with the second engaging portion to form a suction channel in the drinking straw.
  • Consumers can clean an inner part of the drinking straw by disengaging the first engaging portion and the second engaging portion.
  • the drinking straw of the present invention can be cleaned easily, can reduce the cost of manufacture, and can improve suction efficiency.
  • a drinking straw in accordance with the present invention is integrally formed of a food-grade plastic material, is flexible and comprises a sheet body 10, a first engaging portion 20a, and a second engaging portion 20b.
  • the first engaging portion 20a and the second engaging portion 20b are respectively formed on two side edges of the sheet body 10, and the sheet body 10 can be wound into a tubular shape to enable the first engaging portion 20a to engage with the second engaging portion 20b to form a suction channel 30 in the drinking straw.
  • the first engaging portion 20a has a first engaging rib 21a and a first engaging slot 22a formed on the drinking straw along an axial direction of the drinking straw.
  • the first engaging slot 22a of the first engaging portion 20a is formed between the first engaging rib 21a and the sheet body 10.
  • the second engaging portion 20b has a second engaging rib 21b and a second engaging slot 22b formed on the drinking straw along the axial direction of the drinking straw.
  • the second engaging slot 22b of the second engaging portion 20b is formed between the second engaging rib 21b and the sheet body 10.
  • the first engaging rib 21a engages with the second engaging slot 22b
  • the second engaging rib 21b engages with the first engaging slot 22a.
  • the first engaging rib 21a of the first engaging portion 20a has a first limiting flange 211a formed on and protruded from the first engaging portion 20a toward the first engaging slot 22a.
  • the second engaging rib 21b of the second engaging portion 20b has a second limiting flange 211b formed on and protruded from the second engaging portion 20b toward the second engaging slot 22b.
  • the first limiting flange 211a engages with the second engaging slot 22b
  • the second limiting flange 211b engages with the first engaging slot 22a.
  • the drinking straw has a piercing portion 40 formed on a bottom end of the drinking straw, and the drinking straw is integrally made of a silicone material.
  • the consumer when a consumer wants to use the drinking straw of the present invention to drink a beverage, the consumer can engage the first limiting flange 211a of the first engaging rib 21a with the second engaging slot 22b of the second engaging portion 20b, and at the same time engage the second limiting flange 211b of the second engaging rib 21b with the first engaging slot 22a of the first engaging portion 20a, so that the drinking straw can be engaged to form a tubular structure and form the suction channel 30.
  • the consumer can use the piercing portion 40 at the bottom end of the drinking straw to pierce a sealing film of the beverage cup and insert the piercing portion 40 into the beverage cup to suck the beverage.
  • the consumer can suck the beverage in the beverage cup from an end of the suction channel 30 opposite to the piercing portion 40.
  • the consumer can disengage the first engaging portion 20a and the second engaging portion 20b of the drinking straw, so that the first limiting flange 211a of the first engaging rib 21a is separated from the second engaging slot 22b of the second engaging portion 20b, and the second limiting flange 211b of the second engaging rib 21b is separated from the first engaging slot 22a at the same time. Then the consumer can unfold the sheet body 10 to clean the inner part of the drinking straw fully and easily to avoid health and safety issues.
  • the drinking straw of the present invention is integrally made of a silicone material, so during the manufacturing process, the drinking straw of the present invention can be manufactured only by an extruder and cutting equidistantly, which can simplify the manufacturing method and reduce the manufacturing cost.
  • first engaging portion 20a and the second engaging portion 20b are both made of a flexible plastic material, when the first engaging portion 20a and the second engaging portion 20b are engaged with each other, the first engaging portion 20a and the second engaging portion 20b can be airtightly connected with each other. Then, when the consumer sucks a beverage, the suction channel 30 can generate negative pressure, thereby improving the suction efficiency of the drinking straw of the present invention.
  • the drinking straw as described has the following advantages.
  • the drinking straw of the present invention is integrally made of a silicone material. During the manufacturing process, it only needs to be extruded by an extruder and cut equidistantly.
  • the manufacturing process of the drinking straw of the present invention can simplify the manufacturing method and reduce the manufacturing cost.
  • the drinking straw is integrally made of a silicone material.
  • the first engaging portion 20a and the second engaging portion 20b can be airtightly connected with each other. Then, when the consumer sucks a beverage, the suction channel 30 can generate negative pressure, thereby improving the suction efficiency of the drinking straw of the present invention.
