Definitions

• the present invention relates to a self-closing extraction mouthpiece, comprising a valve housing having an axially through-going bore which at one portion thereof is surrounded by an annular, preferably conical valve seat, wherein in said bore a movable extraction pipe has been disposed, said extraction pipe having an annular portion adapted to - in a first position of the extraction pipe - to rest sealingly against the valve seat as well as being maintained resiliently in this sealing position by means of an elastic body, e.g. a screw spring, acting between the valve housing and the extraction pipe, e.g.
• an elastic body e.g. a screw spring
• Such a self-closing extraction mouthpiece may also be used as a drinking mouthpiece, such drinking/extraction mouthpieces generally being intended used on bottles and containers containing thinly-fluid liquid.
• a self-closing extraction mouthpiece of the kind defined in the introduction is known from U.S. patent specification No. 2,841,313 which, however, lacks closing means adapted to prevent unintentional movement of the extraction pipe away from the closing position, wherein it rests sealingly agains the valve seat with the annular sealing portion thereof.
• the object of the invention has substantially bee to eliminate this shortcoming. This has been achieved throug shaping and designing a self-closing extraction mouthpiece o the kind indicated introductorily, such as defined in the characterizing clause of the following claim 1.
• the desired closing means is/are disposed at the outside of the valve housing neck, said closing means being adapted to prevent unintentional movement of the extraction pipe away from said closing position.
• Said closing means may comprise locking knots disposed on said pressure cover, said locking knots being adapted to cooperate with locking grooves formed in the valve housing neck, such that twisting of the pressure cover brings the extraction pipe between closed and open position.
• Said closing means may comprise a sealing belt placed betwee the pressure cover and the valve housing, in order to maintain the pressure cover and, thus, the extraction pipe i the closed position, the sealing portion of the extraction pipe resting sealingly against the valve seat.
• the locking knots may engage guidingly into slide grooves formed in the valve housing neck, and move along these when the pressure cover is twisted in order to bring the mouthpiece to take the open position from the closed positio or to take the closed position from the open position, respectively.
• the drinking/extraction mouthpiece is not in use, it should be locked in the closed position. This is achieved through twisting the pressure cover 30° clockwise. Then, the locking knots will slide into the cut grooves in the valve housing neck, causing the pressure acting on the extraction/drinking mouthpiece to increase, such that carbonic acid gas in a beverage containing the same, cannot leak out. Thus, a child safety lock is also obtained.
• Figure 1 shows an axial section view through a drinking/ extraction mouthpiece in closed position, where an encircled detail of i.a. a locking knot in engagement with a slide groove are shown to the right on a larger scale;
• Figure 2 shows a corresponding axial section view through the mouthpiece in open position, where an encircled detail of i.a. the extraction pipe's lower end and the valve seat are shown to the right on a larger scale;
• Figure 3 shows a side elevational view of the extration mouthpiece, equipped with a sealing belt, hatched;
• Figure 4 shows the extraction mouthpiece of figure 3 seen in a top plan view, and wherein a top face of a pressure cover is marked according to closing/locking and opening the mouthpiece.
• a valve housing 1 of a drinking/extraction mouthpiece is, below the valve housing neck, formed as an inverted cup which, possibly, may have internal threads in order to be screwed onto an outlet of a bottle/container, or it can be pushed/pressed onto the outlet part.
• the valve housing 1 is formed with a through-going bore which, at the transition to the valve housing neck, is formed with a conical valve seat 8.
• an extraction pipe 5 is formed with a sealing portion formed complementarily to the seat 8 and intended to cooperate sealingly with the latter in the closed position of the mouthpiece, figure 1.
• a pressure cover 3 concentric to the extraction pipe 5 is connected to the latter to form a single unit therewith, e.g. through welding.
• a screw spring 4 surrounds the extraction pipe 5 externally, one end of the spring being supported against the top face of the valve housing neck, the other end thereof being supported against the internal face of the top wall of the pressure cover 3.
• the screw spring 4 is a ' pressure spring attending to keep the sealing portion of the extraction pipe 5 in a sealing rest against the valve seat 8 in the closed position.
• the extraction mouthpiece is activated for extraction through subjecting the pressure cover 3 to a downwardly directed pressure, thus moving the inner, closed end of the extraction pipe 5 downwardly, away from the valve seat 8.
• the extraction pipe 5 has a laterally directed hole 2 extending through-goingly through the pipe wall. Whenever the extraction pipe 5 takes an open position, figure 2, the laterally directed hole 2 is in liquid communication with the liquid/beverage within the bottle/container (not shown) .
• two locking knots 6 are disposed on the inner side face of the pressure cover 3.
• these knots runs in cut grooves 7 in the valve housing neck. Twisting the pressure cover 3 clockwise, the locking knots 6 will slide into the cut grooves 7 and lock the mouthpiece in this position. Simultaneously, this locking device serves as a child safety means.
• the self-closing drinking/extraction mouthpiece according to the invention can be produced in PVC or similar materials, except the screw spring which is produced in metal.
