Description

Anti-overflow straw

Technical Field

The utility model belongs to the technical field of daily necessities, concretely relates to anti-overflow straw.

Background

The sucker is a hollow plastic product mostly in a cylindrical shape, is integrally in a slender tubular shape, and is mainly used for drinking beverages in cups. Chinese patent publication No. CN102596742B discloses a spout for an anti-spill beverage container, wherein the spout (12) has: a side wall (18) made of a flexible material defining an outer surface contactable by the lips of a drinker; and an inner surface defining a discharge passage leading to the mouth of the spout so as to allow beverage to be drawn from the container by a drinker. A valve is provided in the discharge passage to avoid undesired spillage of the beverage when no one is drinking from the container. The valve comprises two flanks (16 a, 16 b) integrally formed with the side wall (18) of the spout (12) and projecting from opposite sides of the inner surface of the spout. The front faces of the wings fit into each other along a slit (30) extending parallel to the long axis of the spout. At least the front of the flaps are inclined away from the mouth of the spout (12) so that pressure within the container acts to urge the flaps (16 a, 16 b) towards each other so as to keep the slit (30) closed. Deformation of the side wall (18) of the spout (12) acts to open the slit (30) when the spout is held between the lips of a drinker. In chinese patent publication No. CN110056671a, an overflow preventing tube is disclosed, which comprises a tube wall and a valve; on a plane vertical to the length direction of the pipe wall, the section of the inner side wall of the pipe wall is oval, and the section of the outer side wall of the pipe wall is in a closed ring shape; and in the plane where the elliptical long axis of the inner side wall and the length direction of the pipe wall are located, the section of the valve is of a V-shaped structure and is connected with the inner side wall, and a cutting seam is arranged on the valve and used for conducting fluid in a one-way mode.

In the patent product, the section of the pipe wall of the suction pipe is provided with a long axis and a short axis, and is basically elliptical or racetrack-shaped; the valve or valve for controlling liquid overflow is V-shaped in section, when a user uses the suction pipe, the lips are required to be pressed on the side wall of the long shaft so as to open a cutting seam or a crack on the valve or valve, so that the liquid can be sucked out through the suction pipe, otherwise, the suction pipe fails, and the suction pipe is not easy to use by people, particularly children.

Detailed Description

The technical solutions of the present invention are further described and illustrated below by specific embodiments, so that the present invention is more clear and understood. Other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied in other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

As shown in fig. 1 to 4, the present embodiment relates to an anti-overflow straw, which includes a pipe wall 1, wherein the pipe wall 1 is made of a flexible material, a transverse cross section of the pipe wall 1 is circular, that is, transverse cross sections of an inner side wall 11 and an outer side wall 12 are both regular circular, a valve 2 for closing an in-pipe channel 14 is disposed on the inner side wall 11 of the pipe wall 1 on a port side, and the valve 2 and the pipe wall 1 are integrally formed. Three symmetrically arranged cutting seams are formed in the valve 2 and distributed in a Y shape, the cutting seams 21 are communicated with the upper surface and the lower surface of the valve 2, each cutting seam 21 extends from the central point of the valve 2 to the direction of the inner side wall 11, and when lips press the pipe wall 1 at any angle, the pipe wall 1 is pressed, so that the cutting seams 21 can be opened quickly. The valve 2 is arranged in the pipe wall 1 and is close to one side of the sucking port 15 which is jointed with the lips when a user sucks, and the cutting seam 21 is used for conducting liquid in a one-way mode.

In a specific embodiment, the slits 21 are four in number, and are distributed in a cross shape as a whole, as shown in the figure.

In a specific embodiment, the length of the slit 21 is less than or equal to the distance from the center point 22 of the valve 2 to the inner side wall 11, and the longer the slit, the easier the sucking.

In a particular embodiment, the longitudinal section of the valve 2 is circular arc, the middle of which is concave, as shown in fig. 2 and 3. Since the diaphragm 2 is formed to be concave downward, it is difficult to deform the diaphragm 2 to open the tube inner passage 14 even when the liquid at the lower end of the straw hits the diaphragm 2 in the case that the diaphragm is opened without being deformed, so that the liquid at the lower end of the straw can be prevented from leaking.

In a particular embodiment, the distance C between the highest and the lowest point of the valve 2 is 0.3-2mm, i.e. the distance from the top to the bottom of the circular arc shaped longitudinal section is defined, preferably between 0.5-1.0 mm.

In some embodiments, the thickness of the different portions of the valve 2 shown can be designed to be uniform or non-uniform.

In some embodiments, the valve 2 is shown as having a thin center and thick periphery, with the thinner center design facilitating the fastest upward burst of liquid through the center of the valve 2 to open the slit 21 when the user sucks on the valve. The design of the two ends which are relatively thick and the middle which is relatively thin and uneven wall thickness is beneficial to prolonging the service life of the valve and opening the cutting seam.

In some embodiments, the valve 2 has a valve thickness B of 0.4-2mm. When the overflow prevention straw is applied in a water cup, the valve thickness B of the valve 2 is preferably 0.8mm.

In a specific embodiment, the wall thickness a of the tube wall 1 is 0.1mm to 3.0mm. The wall thickness A of the straw when the straw is applied to a cup for use is preferably 1.6mm.

In a specific embodiment, the upper end surface 13 of the pipe wall 1 is an arc surface which is arched upwards. The lip of laminating more compares the plane shape design, and the arcwall face can reduce the friction of oral area contact surface, and the use sense of touch of lip laminating can be better during the use.

In a specific embodiment, the caliber of the upper end of the pipe wall 1 is larger than that of the lower end. The outer side wall 12 of the tube wall 1 gradually forms an arc-shaped structure towards the upper end of the sucking port 15.

It should be noted that the drawings provided in the above embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.

The foregoing is only a preferred embodiment of the present invention and the technical principles applied thereto. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, the present invention has been described in more detail through the above embodiments. The present invention can also include other equivalent embodiments, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present disclosure should be included in the protection scope of the present disclosure.
