  The invention relates to a straw comprising a tube (11) extending between a first end (13) and a second end (14) and comprising a stopper (12) placed in the tube near the first end thereof and extending between a first end (17) facing the first end of the tube, and a second end (20) facing the second end of the tube, said stopper and said tube being configured such that, after a liquid substance (22) has come in contact with the stopper via the second end thereof, the stopper blocks the passage of the liquid substance therethrough and is, by pushing on the first end thereof, slidable into the tube toward the second end thereof. Moreover, the stopper comprises, on the side of the second end of the tube, a barrier pad (16) consisting of hydrophobic threads over the entire cross-section of the tube.

  本发明涉及一种吸管，该吸管包括一个在第一端（13）和第二端（14）之间延伸的管子（11），该管子包括一个塞子（12），该塞子（12）放置在靠近第一端的管子中，并在朝向管子第一端的第一端（17）和朝向管子第二端的第二端（20）之间延伸、所述塞子和所述管子的构造是，在液体物质 (22) 通过其第二端与塞子接触后，塞子阻挡液体物质通过，并可通过推动其第一端向第二端滑入管子。此外，塞子在管子第二端的一侧还包括一个由疏水螺纹组成的阻隔垫（16），覆盖管子的整个横截面。

  The container straw comprises a tube (11) and a stopper (12) that is permeable to gasses and impermeable to liquids, which stopper (12) is arranged in the tube (11) near one end (16), characterized in that it comprises an indicator component (20) configured to emit, at least when the container straw (10) is full, light the spectrum of which contains at least one spike having a peak of predetermined wavelength. The assembly comprises the container straw (10) and a container straw recognition device (26).

  容器吸管包括一个管子（11）和一个塞子（12），塞子（12）可渗透气体而不渗透液体，塞子（12）布置在管子（11）中靠近一端（16）的地方，其特征在于它包括一个指示部件（20），该指示部件至少在容器吸管（10）装满时可发出光，其光谱包含至少一个具有预定波长峰值的尖峰。组件包括容器吸管 (10) 和容器吸管识别装置 (26)。

  The straw includes a tube (11) extending between a first end (16) and a second end (17) and includes a gas-permeable but liquid-impermeable plug (12). The tube (11) is made of a thermochromic material that reversibly changes colour at a pre-set temperature threshold, by virtue of which colour change the tube (11) has a first visual appearance if the temperature thereof is below the preset threshold and a second visual appearance that is different from the first visual appearance if the temperature thereof is above the preset threshold.

  吸管包括一个在第一端（16）和第二端（17）之间延伸的管子（11），并包括一个气体可渗透但液体不可渗透的塞子（12）。管子（11）由热变色材料制成，在预设的温度阈值下可逆地改变颜色，如果管子（11）的温度低于预设阈值，则管子（11）会因颜色的改变而具有第一视觉外观，如果管子（11）的温度高于预设阈值，则管子（11）会具有与第一视觉外观不同的第二视觉外观。
