Detailed Description

The following describes in detail embodiments of the present invention with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding features.

Fig. 1 schematically shows a perspective view of a first embodiment of a drinking straw according to the invention.

As shown in the drawing, the suction pipe 10 has a hollow cylindrical shape, and a closed slit 11 is formed on a pipe wall thereof.

The slit 11 extends along the entire length of the straw 10 and radially through the wall of the straw 10, thereby enabling the entire straw 10 to be unfolded along the slit 11. Normally, the slit 11 is closed, as shown in fig. 2, effectively creating a seal, thereby forming the straw 10.

In the illustrated embodiment, the slits 11 may be designed to continuously linearly extend between both ends of the suction pipe 10 in order to facilitate the slit process. It will be appreciated that in alternative embodiments, the slits 11 may comprise more than one slit that is not continuous, or may extend only part of the length of the straw 10, as the case may be. In addition, in various embodiments, it is possible to use a non-linear cut, and it is also advantageous to prevent cutting the operator's hands.

According to the utility model discloses a straw 10 is after finishing using, and inside pipe wall can have remaining beverage or other edible materials etc. can conveniently wash this straw 10 before the storage. In particular, the inner wall of the straw can be easily and efficiently cleaned by hand or a cleaning tool simply by unfolding the straw along the slit 11.

In order to enable the straw 10 to automatically close along the slit 11 after being unfolded, the straw may be made of an elastic material, such as, but not limited to, silicone (silicone) or the like. Tests show that after the straw 10 made of the material is unfolded along the cutting seam 11 and cleaned, the section of the cutting seam 11 can be automatically closed, so that the cutting seam 11 can be automatically restored to the initial sealing state, and the straw is convenient to use again.

In order to provide the straw with sufficient elastic force and slit sealing effect, the wall of the straw 10 may have a certain thickness, for example, but not limited to, the thickness of the wall may be between 1 mm and 3 mm. Can increase the resilience force of straw, increase the cross sectional area of lancing department effectively like this, promote the sealed effect of lancing department.

Figure 2 shows schematically an end view of the suction tube of figure 1.

As will be understood from fig. 2 and 1, in this embodiment, the section 12 of the straw 10 at the slit 11 may be a plane, and this arrangement enables the opposite section 12 at the slit to be more closely fitted to facilitate the sealing effect. In addition, since the adhesion gap between the plane cross sections is very small, a water film is formed after moisture enters, which contributes to further improvement of the sealing effect.

In order to increase the area of the cross-section to improve the sealing effect, the plane of the cross-section 12 may be tangential to the inner circumferential wall 13 of the straw in the illustrated embodiment. It should be noted that the cross-section at the slits may be at other angles or directions in other embodiments, as the case may be.

Figures 3 to 5 show schematically end views of second to fourth embodiments of a drinking straw according to the invention, respectively.

In fig. 3 to 5, the two sections of the straw opposite to each other at the slit are curved surfaces with complementary shapes. For example, fig. 3 shows a circular arc cross-section combination 14; in fig. 4, a ridge section combination 15 is shown; fig. 5 shows the locking part combination 16 in two sections. It can be seen that, illustratively, one of these combinations of sections is formed with a recess and the other is formed with a complementary protrusion.

Under the action of elastic restoring force of the suction pipe, the concave-convex connection of the cross sections is easy to abut against each other, which is beneficial to sealing the cutting seam; in addition, the bent water film in the bent section has stronger anti-seepage capability, and the sealing effect in the sucking process can be better.

In other embodiments, the locking of the two sections can also be achieved by magnetic material, rather than by the elastic restoring force of the pipette. In some further embodiments, such as fig. 5, manual pinching, snap locking of the combination 16 may also be used. Alternatively, in alternative embodiments, these approaches may be used in combination.

Fig. 6 to 7 schematically show side views of fifth to sixth embodiments of a drinking straw according to the invention, respectively.

It can be seen that, unlike the straight slit 11 of the straw 10 of FIG. 1, in FIG. 6, the slit 17 of the straw extends along a wavy line; in fig. 7, the slit of the straw extends along a serrated line 18.

In an alternative embodiment, the slit of the straw may also extend along a helical line (not shown).

The cross-sectional and slit designs of figures 3-7 all facilitate preventing the slit from cutting the operator's hand when the straw is manually deployed.

Figures 8 and 9 schematically show a side view and an end view, respectively, of a seventh embodiment of a drinking straw according to the invention.

As shown in the drawings, the pipette 20 has a projection 22 on its outer surface, and the projection 22 may be arranged on both sides of the slit 21 and adapted to be manually operated to spread the pipette apart to facilitate the washing of the pipette. In an alternative embodiment, the projections may be arranged only on one side of the slit 21.

Although the embodiment in the figures provides a raised portion at only both ends of the straw 20, it is contemplated that a raised portion may be provided at only one end of the straw 20; alternatively, the projections may be distributed along the entire length of the straw 20 along the slit to facilitate deployment of the straw 20 at various locations along the length of the straw.

The features of the cross section, the slit, the protrusion and the like in the above embodiments can be combined with each other to form a new embodiment of the present invention. These new embodiments are also within the scope of the present invention.

In addition, it should also be noted that while the present invention is described in connection with a straw having a circular cross-section in the figures of the present application, various improved features of the present invention, such as, but not limited to, slits, sections, lobes, and the like, are equally applicable to straws having non-circular cross-sections.

The technical scope of the present invention is not limited to the above description, and those skilled in the art can make various modifications and alterations to the above embodiments without departing from the technical spirit of the present invention, and all such modifications and alterations should fall within the scope of the present invention.
