Definitions
- the present application relates to the technical field of drinking straw, and more particularly to a resealable drinking straw which allows washing of the drinking straw's interior.
- Drinking straw being a handy tool for drinking, is widely used in catering industry. It is well known that plastic is durable, cheap and easy to manufacture. With these properties, a vast amount of plastic drinking straw is produced yearly and entered to the market. Although there is more environmental friendly materials like bamboo, or Paper are recommended, the single use drinking straw find their way into the waste cycle or enter into waste fills or even end up as stray waste polluting our lands, rivers and oceans. Obviously, the abundant use of any one-off cutlery creates an enormous waste problem to society. On the other side, it is difficult to completely abandon the use of disposable drinking straw as it requires drastic change of personal behavior in the society.
- washable drinking straw which allows the user to wash the interior is available in the market.
- This type of drinking straw is commonly made of stainless steel for durability.
- the washing can be done by inserting a long slim brush into the drinking straw to clean debris. Apart from this physical cleaning, sterilization may also perform for extra cleanliness. Nonetheless, people still refuse to use this washable drinking straw due to the hygiene issue.
- cleanliness of this washable drinking straw is doubtful. Accordingly, there is a need for a drinking straw that can be reused and washed easily so that the cleanliness can be ensured before use.
- a resealable drinking straw comprising a straw body which comprises a first sidewall, a second sidewall and a bending portion, the first sidewall is connected with the second sidewall by the bending portion to form a tubular shape; a hollow portion, defined by the first sidewall, a second sidewall and the bending portion and extends along a axial length of the straw body; an opening, defined by opposing edges of the first sidewall and the second sidewall, extending axially along the straw body; particularly, the opening is closed by mating the first sidewall and the second sidewall to allow fluid passage through the hollow portion.
- the straw body comprises a male and female connection means, the male and female connection means are respectively disposed along the opposing edges of the first sidewall and the second sidewall, the opening is closed by connecting the male and female connection means.
- the male connection means is a tongue extends circumferentially
- the female connection means is a groove with circumferential depth which is capable to receive the tongue.
- the tongue comprises a protrusion facing radically outward and extending axially along the straw body.
- cross sectional shape of the protrusion is a trapezoid.
- thickness of the bending portion is smaller than that of the first sidewall and the second sidewall.
- the straw body is made of flexible plastic material. In yet another embodiment, the straw body is made of silicone material.
- cross sectional shape of the straw body is triangle, square, hexagon, oval, rectangular, rhombus, trapezoid, pentagon or octagon.
- straw body 10 first sidewall 21, second sidewall 22, bending portion 23, hollow portion 30, opening 31, connection means 5, tongue 51, groove 52, protrusion 511 and 512.
- first and second are for illustrative purposes only and should not be construed as indicating or implying a relative importance or implicitly indicating the quantity of technical features indicated. Therefore, a feature that defines “first” and “second” may expressly or implicitly include one or more of the features.
- “multiple” means two or more than two, unless otherwise specifically defined.
- a resealable drinking straw including a straw body 1 which comprises a first sidewall 21, a second sidewall 22, a bending portion 23 and
- the straw body 10 is in tubular shape with an opening extending alongside the axial length of the straw body 10.
- the opening allows the user to wash the interior of the straw body from the lengthy side, instead of rinsing the straw body from both ends.
- the resealable drinking straw in the present application is made of flexible material to achieve maximum resilience such that the straw body could return to its original state after cleaning.
- Fig. 2 is a sectional view of the resealable drinking straw provided by an embodiment of the present application.
- the straw body 10 comprising a first sidewall 21, a second sidewall 22 and a bending portion 23.
- the first sidewall 21 is connected with the second sidewall 23 by the bending portion 23 to form the tubular shape as illustrated in Fig. 1 .
- a hollow portion 30 is therefore formed which is defined by the first sidewall 21, a second sidewall 22 and the bending portion 23. Accordingly, the hollow portion 30 extends along the axial length of the straw body 10 which allows fluid passage when suction is applied to the end of the straw body 10.
- the straw body 10 comprising an opening 31 defined by opposing edges of the first sidewall 21 and the second sidewall 22. Moreover, the opening 31 also extends along the axial length of the straw body10. When the straw body 10 is opened for washing, the opening 31 is the entrance to the interior of the straw body 10.
- a connection means 5 is disposed on the first sidewall 21 and the second sidewall 22. As the first sidewall 21 and the second sidewall 22 are intrinsically connected by the bending portion 23, connection means 5 further connects the sidewalls 21, 22 to form a closed cross sectional area/space, which is the hollow portion 30.
- the opening 31 is said to be closed by mating the first sidewall 21 and the second sidewall 22 via the connection means 5.
- the sealed opening 31 allows fluid passing through the hollow portion 30 when suction is applied to the straw body 10. It is important to close the opening in a manner that no air or water could be leak in/out.
- the connection means 5 play an important role in providing a leak-proof straw body 10.
- connection means 5 is a male and female connection
- a male and a female connector are disposed respectively on the opposing edges of the first sidewall 21 and the second sidewall 22.
- the male and the female connector extend along the axial length of the first sidewall 21 and the second sidewall 22.
- a straw body 10 comprising a first sidewall 21, a second sidewall 22 and a bending portion 23.
- the first sidewall 21 is connected with the second sidewall 22 by the bending portion 23 to form a tubular shape.
- An opening defined by the opposing edges of the first sidewall 21 and the second sidewall 22 is extending axially along the straw body 10.
- the opening 31 is closed by mating the first sidewall 21 and the second sidewall 22 to allow fluid passage through the hollow portion 30.
- first sidewall 21 and the second sidewall 22 are further connected by a tongue and groove connection.
- a tongue 51 is disposed on the edge of the first sidewall 21 and extends axially along the first sidewall 21.
- a groove 52 is disposed on the edge of the second sidewall 22 and extends axially along the second sidewall 21. As the groove 52 is provided with the same shape and size of the tongue 51, the matching of tongue 51 and groove 52 completely closed the opening 31. Accordingly, the straw body 10 is sealed to provide a hollow portion 30 for suction.
- a protrusion 511 is disposed on the tongue 51.
- the protrusion 511 aims to strengthen the connection between the tongue 51 and groove 52.
- the protrusion 511 extends axially along the straw body 10 and fit in completely into the groove 52.
- the protrusion 511 is disposed on the outer side of the tongue 51, facing radically outward. This protrusion 511 provides an auxiliary connection between the first sidewall 21 and second sidewall 22. When there is a pressure change in the hollow portion 30 during suction, the protrusion 511 helps to hold the shape of the straw body 10 and prevent deformation.
- the bending portion 23 is designed with a smallest thickness compared with the first sidewall 21 and second sidewall 22. It makes the bending of the straw body 10 easier, so that the user could flatten the straw body 10 from the opening 31 and clean the interior more thoroughly.
- the tongue 51 is modified to include two protrusions.
- the protrusion 511 and protrusion 512 extends axially along the straw body 10 and fit in completely into the groove 52.
- the protrusion 511 is radically facing outward while protrusion 512 is radically facing inward.
- both protrusions 511, 512 are fitted into the groove 52 to secure the connection between the first sidewall 21 and second sidewall 22. It helps to resist the deformation acting inwardly or outwardly to the straw body 10, therefore, providing a good sealed condition for suction.
- the diameter and length dimensions of straw body 10 may be varied for different usage.
- the straw body 10 may have an approximate length of 220mm, an outer diameter of 9mm so as to provide a desired flow rate and leak proof effect.
- the length of the straw body ranges from 50mm to 300mm and the diameter of the straw body ranges from 5mm to 40mm.
- the straw body 10 may further be manufactured in different shape.
- the cross section of a closed straw body 10 is circle, thereby, forming a cylindrical drinking straw.
- the straw body 10 is manufactured in other shape, such that its cross sectional shape is triangle, square, hexagon, oval, rectangular, rhombus, trapezoid, pentagon or octagon.
- the resealable drinking straw is preferably made of flexible material, for instance, silicone rubber material. Food grade material with flexibility is also suitable.
- the resealable drinking straw is preferably made of natural rubber or thermoplastic rubbers. For example, TPE (Thermo Plastic Elastomer) / TPR (Thermo Plastic Rubber).
- the resealable drinking straw of the present application has the following beneficial effects: Meanwhile, resealable drinking straw allows user to clean the interior of the drinking straws. Thus, the hygiene can be guaranteed. It encourages the diner to reuse the drinking straw and thereby reduce the pollution due to the disposal of any one-time use drinking straw.
