CONTENT OF THE UTILITY MODEL

[0005] In view of the above problem, the utility model provides a tip hidden type safety straw, the straw adopts the form of double tubes, the tip of the core pipe is hidden in the sleeve pipe, is not directly exposed outside, the safety is greatly improved, reduces the occurrence of pricking event, and is convenient to use.

[0006] To solve the above problem, the technical scheme that the utility model adopts is:

[0007] A tip hidden type safety straw, including core pipe and sleeve pipe, the front end of the core pipe is the tip part, the sleeve pipe is sleeved on the core pipe, the tip part of the core pipe is located in the sleeve pipe, the tail end of the core pipe is the extension part, the extension part extends out from the tail end of the sleeve pipe;

[0008] The both sides of the tip part are equipped with the convex point;

[0009] When using, hold the sleeve pipe, press the extension part with the thumb, make the tip part resist from the sleeve pipe, then pinch the sleeve pipe, and the tip part is pricked into the container.

[0010] Preferably, the convex point is integrally formed with the tip part, and the inner wall of the sleeve pipe is provided with a groove matched with the convex point.

[0011] Preferably, the core pipe and the sleeve pipe are in interference fit.

[0012] Preferably, the tip part is conical.

[0013] Preferably, the tip portion is a bevel cut, and the tip portion end is provided with a spike.

[0014] Preferably, the length of the sleeve is much smaller than the length of the core tube.

[0015] The utility model has the advantages of:

[0016] 1. By adopting the form of double tubes, the tip of the core tube is hidden in the sleeve and is not directly exposed, the safety is greatly improved, and the occurrence of pricking events is reduced.

[0017] 2. The length of the core tube is greater than that of the sleeve, before use, the extension of the core tube is extended out of the sleeve, during use, only the sleeve needs to be held, the big thumb is pressed on the extension, the tip can be pushed out of the sleeve, and the use is convenient.

[0018] 3. The core tube and the sleeve adopt the form of interference fit, and are provided with convex points and recesses, the two have certain frictional resistance, a certain force needs to be applied to move the core tube, the protection effect is improved, the two will not be separated, and the tip will not be retracted into the sleeve during the process of pricking and piercing.

[0023] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0024] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. As used herein the terms "vertical", "horizontal", "left", "right", and the like are used for explanation only and are not intended to be limiting.

[0025] Embodiment 1

[0026] With reference to Figures 1-2 A safety straw with hidden tip, comprising a core tube 1 and a sleeve tube 2, the front end of the core tube 1 is a tip 11, the sleeve tube 2 is sleeved on the core tube 1, and the tip 11 of the core tube 1 is located in the sleeve tube 2.

[0027] Further, the tail end of the core tube 1 is an extension 12, the extension 12 extends out of the tail end of the sleeve tube 2, facilitating the quick protrusion of the tip 11, and in use, only need to hold the sleeve tube 2 and press the extension 12 with the thumb to protrude the tip 11 out of the sleeve tube 2.

[0028] Further, the tip 11 is conical, the tip 11 can also be chamfered, and the tip 11 has a spike at the end.

[0029] Further, both sides of the tip 11 are provided with protrusions 13, the protrusions 13 are integrally formed with the tip 11, the inner wall of the sleeve tube 2 is provided with grooves 21 matched with the protrusions 13, the core tube 1 and the sleeve tube 2 are in interference fit, and there is a certain frictional resistance between the two, and a certain force needs to be applied to move the core tube 1 or the sleeve tube 2.

[0030] Further, the diameter of the core tube 1 is 6.7mm, the diameter of the sleeve tube 2 is 7.4mm, and the inner diameter of the sleeve tube 2 is 6.7mm, at this time the interference amount is zero, and can also be greater than zero, further improving the frictional resistance.

[0031] Further, the length of the core tube 1 is 230mm, the length of the sleeve tube 2 is 200mm, and the extension length of the extension 12 is 30mm, meeting the use of most products on the market.

[0032] When the straw is not in use, the tip 11 of the core tube 1 is hidden in the sleeve 2 and is not directly exposed to the outside, which greatly improves safety and reduces the occurrence of puncture injuries. The length of the core tube 1 is greater than that of the sleeve 2. Before use, the extension 12 of the core tube 1 extends out of the sleeve 2. When in use, one only needs to hold the sleeve 2 and press the extension 12 with the thumb to push the tip 11 out of the sleeve 2. Then, by pinching the sleeve 2 or keeping the gesture of pressing the extension 12, the tip 11 can be quickly inserted into the bottle. During the rapid puncture process, since the core tube 1 and the sleeve 2 are in the form of interference fit, there is a certain friction resistance between the two, and the tip 11 will not retract into the sleeve 2.

[0033] Example 2

[0034] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the length of the sleeve 2 is much smaller than the length of the core tube 1. The length of the sleeve 2 can be 30 mm, which is greater than the length of the tip 11. While ensuring that the tip 11 is hidden, the consumables of the sleeve 2 are greatly reduced, thereby reducing the cost. When in use, the sleeve 2 can be pulled to the tail end of the core tube 1.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
