Definitions

  • the invention relates to a closable container for dispensing viscous substances, such as creams, according to the preamble of patent claim 1.
  • a container of this type is known from DE 39 28 524 A1.
  • This container is provided with two hollow pistons which can be moved coaxially with respect to one another, one of which is seated on the pump base and the other on an actuating button which runs out into a mouthpiece.
  • the container is equipped with a bellows through which the actuation button can be axially reset and which extends from a pump device to the upper region of the first-mentioned hollow piston.
  • the bellows is provided with a piston ring which bears against the inside of the first hollow piston mentioned above. In the space between the dispensing valve and an outlet opening, the contents of the container can settle and come into contact with air, which is contained in a mouthpiece and in a protective cap.
  • the contents of the container left therein can harden or otherwise experience a deterioration in quality, which makes further use of the container and its contents questionable, e.g. B. unsanitary.
  • the container is therefore unsuitable for dispensing substances that meet the highest requirements for quality stability, e.g. B. sterility.
  • the German utility model 90 05 014.2 describes a cream dispenser that can only be closed airtight by a lid, because an inner lid has a dispensing opening that can only be closed by the lid separated from the container.
  • a secure closure of the opening in the inner lid by the lid that can be placed on the container is not guaranteed, because the cream that has escaped through the opening on the top of the inner lid experiences a quality impairment in the space remaining between the lid and the inner lid due to the air contained therein. that does not meet all requirements for the quality of a cream and leads to losses of usable cream.
  • the delivery opening may be blocked by the cream curing.
  • the invention is based on the object to provide a container of the aforementioned type which, despite frequent removal of the substances contained therein, free of preservatives, maintains the shelf life of these substances over a satisfactorily long period of time and, at the same time, as simple as possible, metered removal of the substance contained in the container is ensured.
  • the container according to the invention has an inner lid which closes an upper opening of the container in an airtight manner and, by means of an actuating device integrated in the inner lid and a cooperating, self-closing check valve, permits removal of a substance contained in the container without the container having to be opened.
  • This is achieved in that an excess pressure is generated in the container by means of the pneumatically acting actuating device, which leads to the opening of the self-closing check valve and at the same time ensures that the substance contained in the container exits through the valve opening. This prevents air from entering the container.
  • germs or bacteria from the surroundings of the container cannot enter it and do not have a negative effect on the shelf life of the substance contained therein.
  • the pneumatic actuating device consists of an outwardly convex or dome-like, form-elastic elevation of the inner cover with a reduced wall thickness compared to a cover base of the inner cover.
  • This advantageous embodiment of the pneumatic actuation device enables it to be formed in one piece with the inner cover. Due to the shape-elastic design, the actuating device can be actuated practically as often as desired by finger pressure.
  • the self-closing check valve has a valve seat formed in the cover base and a valve body movable against the valve seat, the Valve body is held in the closed position by a spring device connected to the inner cover.
  • the spring device acting on the valve body ensures that after the overpressure generated by the pneumatic actuating device in the container has been released, the check valve is reliably returned to its closed position in a sealing manner.
  • the check valve thus remains open only as long as substance is released from the container through the check valve to the outside. This prevents harmful substances from the environment from entering the container through a check valve which is still in the open position after the substance has been released, for example due to a suction effect of the resetting pneumatic actuating device.
  • the entire self-closing check valve consists of only two parts, the connection of which via the latching connection is very simple, i. H. without tools. This results in considerable advantages for the manufacture of the container according to the invention or its inner lid.
  • the embodiment according to claim 4 is particularly suitable if an opening of the self-closing check valve transverse to the plane of the inner cover is desired.
  • the spring element can have one end via a film joint with one transverse extension and the other Be connected at the end via a snap connection to the other transverse extension, so that the spring device can be manufactured in one piece.
  • the embodiment according to claim 6 makes it possible in a particularly advantageous manner to design the pneumatic actuating device and the self-closing check valve to have the same effect on the outside, as well as shaping corresponding to particular aesthetic requirements.
  • a removal space is created on the outer surface of the inner lid, from which the container contents can be removed in a metered form.
  • the embodiment according to claim 8 proves to be advantageous in any case.
  • Such a gap narrows during a closing movement of the check valve, so that a wedge effect occurs, through which a substance that may have accumulated in the gap when the container contents were released is squeezed out and the gap thus remains free of material residues.
  • a further embodiment of the container according to the invention which has significant advantages is specified in claim 9.
  • the inner lid covers the surface of the material contained in the container in an airtight and floating manner.
  • the inner lid is always adjusted to the fill level of the substance.
  • the relative position of the inner lid with respect to the container thus provides the user with information at any time about how much of the ingredient is still contained in the container.
  • Fig. 1 shows a container 10 for receiving a substance, not shown here, such as a cream, with an inner lid 12 which is inserted into the container as a separate part.
  • the container 10 is provided with a cap 13.
  • the closure cap 13 can be omitted without adversely affecting the advantageous effects described below, which characterize the container 10.
  • the inner cover 12 shown in FIG. 1 has a cover base 14 which is provided with a peripheral sealing edge 15.
  • the peripheral sealing edge 15 lies sealingly against an inner wall 16 of the cup-shaped container 10 in a manner which is described in more detail below.
  • a pneumatic actuation device 17 and a self-closing check valve 18 are integrated in the cover base 14 of the inner cover 12.
  • the actuating device 17 consists of an outwardly convex, dome-like elevation 19 which is formed in one piece with the lid base 14 and has a smaller wall thickness than this.
  • the wall thickness is preferably in the center of the elevation 19 least. If necessary, the elevation on the underside can be provided with a plurality of ribs radial to its center, by means of which the restoring effect of the elevation is supported after it has been actuated.
  • the check valve 18 has a valve seat 20 and a valve body 21 cooperating therewith.
  • the valve seat 20 has the shape of a trough 22 which is closed by a valve head 23 of the valve body 21.
  • the valve head 23 has on its underside a valve tappet 24, the free end of which is designed as a spherical locking pin 34 which firmly but releasably engages in a locking opening 35 of a spring element 25 of a spring device 26 and forms a locking connection 33.
  • the spring element 25 exerts a closing force 37 which forces the valve head 23 into the closed position shown in FIG. 3.
  • the spring device 26 consists of two transverse extensions 27, 28, which project downward from the cover base 14, and of the spring element 25, which at its left end in FIG. 1 is integral with a film joint 29 of the inner cover, which is made of plastic 12 is connected to the transverse extension 27.
  • the spring element 25 has a locking pin 30 which engages in a locking opening 32 of the transverse extension 28 shown in FIG. 6 and forms a locking connection 31.
  • the spring element 29, which is connected in one piece to the transverse extension 27 via the film joint 29, can be pivoted with its free end against the transverse extension 28 until a firm, if necessary, snap-in of the locking pin 30 into the locking opening 32 (FIG. 6) releasable locking connection 31 is given.
  • Fig. 2 shows a top view of the inner cover 12, the actuating device 17 and the valve seat 20 in a circular configuration, the trough 22 of the valve seat 20 being closed centrally by the valve head 23 of the valve body 21, so that the valve head 23 is a bottom part of the Trough 22 forms.
  • the container 10 has a circular cross section in the embodiment shown here.
  • the container with a cross-section that deviates therefrom, for example delimited by a polygon, in which case the inner cover 12 and in particular its peripheral sealing edge 15 then have a correspondingly designed circumference.
  • FIG. 3 and 4 the area of the check valve 18 circled in FIG. 1 and designated by X is shown enlarged. 3 shows the check valve 18 in a closed position and FIG. 4 shows the check valve 18 in an open position.
  • valve head 23 of the valve body 21 is frustoconical and seals with its peripheral edge the valve seat 20 which has a valve opening 36 which is adapted to the circumference of the valve head 23.
  • the open position of the check valve 18 shown in FIG. 4 is achieved in that an operator exerts a pressure on the pneumatic actuating device 17 shown in FIG. 1 from the outside, which pressure in the container 10 closed by the inner lid 12 (FIG. 1) leads to overpressure.
  • the overpressure acts, as is shown schematically in FIG. 4 by the arrows 38, on the underside of the valve head 23.
  • This generates an opening force which counteracts the closing force 37 of the spring element 25 and which forces the valve body 21 to discharge the contents of the container into the one shown in FIG. 4 brings open position shown.
  • an opening gap 39 is present between the valve head 23 and the valve seat 20, through which the excess pressure can escape, so that the valve body 21 is brought back into the closed position shown in FIG. 3 as a result of the closing force 37 formed by the elastic restoring force of the spring element 25 becomes.
  • FIG. 5 shows an enlarged illustration of the cross-sectional area of the peripheral sealing edge 15 encircled in FIG. 1 and designated Y.
  • the sealing edge 15 consequently has two circumferential sealing lips 40, 41 which, together with the inner wall 16 of the container 10, form an annular sealing space 42 .
  • a locking element 43 is arranged at the level of the main plane of the inner cover 12, which protrudes radially outward into the sealing space 42 and is directed obliquely upwards and rests against the inner wall 16 of the container 10 with elastic prestress.
  • This preload exerted by the locking element 43 is so large that the locking element 43 prevents an upward movement of the inner lid 12 in the direction of the container opening, but enables a sliding movement downward towards the bottom of the container. In this way, tilting of the inner cover 12 is also counteracted.
  • annular locking element 43 instead of the circumferential, annular locking element 43, if necessary, can be used as a locking element. also several cramps can be arranged, which, similar to the annular locking element 43, lie obliquely upwards against the inner wall 16 of the container 10 with prestress, but are otherwise distributed at angular intervals over the circumference of the inner cover 12.
  • the sealing lips 40, 41 serve primarily to secure the inner cover 12 in the event of a relative displacement, indicated by the arrow 44, with respect to the inner wall 16 of the container 10 seal securely and prevent tilting of the inner cover 12.
  • the inner lid 12 is in its uppermost position, the upper sealing lip 40 being arranged at the level of a parting line 45 which separates the closure cap 13 from the container 10.
  • Fig. 6 which has already been referred to in connection with the explanation of Fig. 1, shows in a bottom view of the inner cover 12, the spring device 26 with the spring element 25, which receives the locking pin 34 of the valve body 21 and in turn with the right end arranged locking pin 30 is received in the transverse extension 28.
  • an inner cover 46 which correspond to parts or elements of the inner cover 12 are provided with identical reference numerals.
  • the inner cover 46 has a self-closing check valve 47 which has an upwardly convex valve seat 48.
  • a valve body 49 interacts with the valve seat 48, the valve head 50 of which has a convex surface corresponding to the valve seat 48.
  • the valve body 49 is designed as a valve tappet 51 and is provided at its free end with a spherical locking pin 52 which is part of a locking connection which corresponds to the locking connection 33 described above with reference to FIG. 1.
  • an inner cover 57 is designed as a scoop-shaped depression 58, with a valve body 60
  • the low point of the trough 58 is adjacent and is arranged in a wall region 62 which is steeper than a trough outlet 61.
  • the valve body 60 is provided with a plate-shaped valve head 71 which seals a valve seat 63.
  • a spring device 64 can be seen, which has a transverse extension 72 which projects from a cover base 65 of the inner cover 57.
  • the connection of the spring device 64 to a valve tappet 66 again takes place via a latching connection 67 between a pin 68 of the valve tappet 66 and a latching opening 69 of the spring device 64.
  • the valve seat 63 becomes radially outward in the direction of opening approximately transversely to the container axis 70 moved relative to the valve head 71 and returns to the closed position after the actuation device 17 has been released.
  • the inner cover 57 of the container 10 shown in FIGS. 8 and 9 is particularly suitable for one-handed operation.
  • the container can be made from different materials, it is preferred to make it from plastic.
