Syringe assembly including plastic tip cap |
摘要 |
A syringe assembly includes a plastic cap (<HIL><PDAT>20</BOLD><PDAT>) that has an end wall (<HIL><PDAT>22</BOLD><PDAT>) and a side wall (<HIL><PDAT>24</BOLD><PDAT>). The end wall (<HIL><PDAT>22</BOLD><PDAT>) preferably includes a plug portion (<HIL><PDAT>64</BOLD><PDAT>) that extends away from an inner surface (<HIL><PDAT>62</BOLD><PDAT>) of the end wall (<HIL><PDAT>22</BOLD><PDAT>). The side wall (<HIL><PDAT>24</BOLD><PDAT>) includes an inner surface (<HIL><PDAT>28</BOLD><PDAT>) that has an engaging portion that sealingly engages a corresponding surface on a syringe. The engaging portion preferably includes two generally annular ribs (<HIL><PDAT>34</BOLD><PDAT>) and (<HIL><PDAT>36</BOLD><PDAT>). An interference fit is provided between the engaging portion and a corresponding surface on the syringe to maintain a sterile seal where the engaging portion contacts the syringe. The plug portion is received within an opening in the syringe and maintains a sterile seal at that point while simultaneously maintaining any medicament within the syringe.</PTEXT>
