    Abstract: An absorbent mat includes top and bottom layers of thermoplastic material with absorbent media disposed therebetween. The top and bottom layers are bonded directly together, or to the absorbent media disposed therebetween, in spaced-apart bond sites. One or more perforations are formed as a result of bonding in the top and/or bottom layers in a peripheral portion of each bond. Each perforation is in communication with the absorbent media and provides a pathway through which liquid can pass. The top and bottom layers may be monolithic thermoplastic film with an aperture formed therethrough at each respective bond by stretching the multi-layer absorbent mat. One or more perforations are formed in the peripheral portion of each bond site thereof as a result of stretching. Each perforation is in communication with the absorbent media and provides a pathway through which liquid can pass into the absorbent media.

    Abstract translation: 吸收垫包括顶层和底层的热塑性材料,其间设有吸收介质。 顶层和底层直接结合在一起,或者与设置在其间的吸收介质粘合在间隔开的粘结位置。 通过在每个键的周边部分中的顶层和/或底层中的结合形成一个或多个穿孔。 每个穿孔与吸收介质连通,并提供液体可以通过的通道。 顶部和底部层可以是通过拉伸多层吸收垫在每个相应接合处形成有穿孔的整体式热塑性薄膜。 作为拉伸的结果,在其每个键合位置的周边部分中形成一个或多个穿孔。 每个穿孔与吸收介质连通,并提供液体可以通过该通道进入吸收介质的通道。
