  • Publication number: 20250161168
    Abstract: A pacifier may include a frame and a mouth shield secured to the frame at least partially by an overmold. An interface between the mouth shield and the frame may be continuous. A method for making a pacifier may include securing a frame in a shield mold defining a mouth shield cavity. The method may further include introducing a curable precursor material into the shield mold. The method may further include overmolding at least a portion of the curable material across at least a portion of the frame in the mold. The method may further include allowing the curable material to cure in the mouth shield cavity into a mouth shield at least partially secured to the frame by an overmold. An interface between the mouth shield and the frame may be continuous.

  • Patent number: 10835065
    Abstract: The present disclosure is directed to a drinking vessel that can include a drinking container and a drinking attachment that is coupled to the container. A straw can be positioned through an opening in the drinking attachment. The straw can include a top end that includes an opening through which a user can withdraw liquid and a bottom end. A drinking valve can be positioned along the bottom end of the straw and can include a tube that is open on the top and closed on the bottom and further includes at least one flow-through opening connecting the inside of the valve to the outside of the straw. A suction tube can include a tube wall that can be slid over the valve to couple the straw to the suction tube.

  • Patent number: 9522769
    Abstract: Push-pull closure for a drink container comprising a body element which comprises a through-opening and a fastening device, with which it may be sealingly and releasably connected to an opening of the drink container, a mouthpiece which may be axially displaceably inserted into the through-opening of the body element and which comprises at least one locking portion which may engage behind the through-opening of the body element, and a locking element which may be releasably attached to the inner face of the body element facing the drink container, the locking element being arranged so that the locking portion of the mouthpiece may not adopt a position in which it does not engage behind the through-opening of the body element, when the mouthpiece is inserted into the through-opening and the locking element is attached to the inner face of the body element.

  • Publication number: 20030220615
    Abstract: The syringe, especially a pre-filled one-time-use syringe, has a syringe body, which is provided with a storage chamber for a liquid to be injected, and a piston with a piston rod so that the piston is axially slidable in the storage chamber. The syringe body has a finger rest and a stop member for limiting the axial motion of the piston at one end and the finger rest is in one-piece with the stop member, which includes at least one projecting element extending into the syringe body. The syringe has a syringe body with a radially outwardly extending flange section, which is formed for a forming-fitting and/or force-locking engagement with at least one catch region provided in the finger rest in order to securely hold the finger rest on the syringe body.

  • Publication number: 20030220613
    Abstract: The syringe, especially a pre-filled one-time-use syringe, has a syringe body, which includes a cylindrical supply chamber for a liquid to be injected and a piston with a piston rod axially connected to it. A finger support is provided at one end of the syringe body and an end portion for holding a hollow needle is provided at the other end of the syringe body. The hollow needle is clamped in a needle channel provided in the end portion. A method of making a syringe body is described, in which the cylindrical storage chamber is made in one piece with a threaded connector by an injection molding process, the end portion provided with the hollow needle clamped in it is made in another injection molding process and then after making the end portion and the cylindrical storage chamber the cylindrical storage chamber is connected with the end portion.
