Definitions

  • the invention relates to a container designed in particular in the manner of a tube with an ejection piston, e.g. B. for deodorant sticks, lipsticks or the like, the closed by a cap-shaped cover, sleeve-shaped housing at the lower edge is cross-sectional width than in the cylindrical central portion.
  • an ejection piston e.g. B. for deodorant sticks, lipsticks or the like
  • a container of this type is known from DE-PS 12 07 862.
  • the lower edge is shifted further outwards by step-like wall offset, so that there is an enlarged standing edge.
  • the offset corresponds to the multiple wall thickness of the sleeve-shaped housing, which is kept open on the bottom side, in order to be able to displace the ejection piston in the dispensing direction, for example by finger actuation.
  • the upper end merges into a reduced-cross-section mouthpiece, which is overlaid by the cap-shaped cover, which can also be used as an additional pushing aid for the extrusion piston.
  • the assignment of the pressure piston is difficult insofar as the stepped offset forms a sharp edge on the inside of the container; it requires particularly careful introduction.
  • the plunger can still tilt slightly.
  • the peripheral sealing surface on the plunger can be damaged, so that the inner wall of the container is not wiped clean.
  • the sharp edge can also cause injuries to the operating finger when pushing the plunger.
  • the object of the invention is to design a generic container in a technically simple, more convenient manner so that the filling can also be accomplished more cheaply.
  • the concave curvature can advantageously be formed by a sealing insert of the cover, so that even a double function is achieved in this regard. It is also advantageous that the upper side of a hollow press-out piston has an opening with the opening edge projecting inwards over the piston wall. Pressing the plunger onto the pin-forming mass pushes the contacting section somewhat into the opening, with a slight bulge-like grip behind the opening edge. This has the advantage that, even during long breaks in use, the extrusion piston cannot detach from the pin-forming mass and falls depending on the weight.
  • the hollow-shaped press-out piston has a clipped-in plate at the lower end which is supported on radially and longitudinally extending ribs of the inner wall of the piston. Since - by that further the mantle wall of the lid collar about by the amount projecting beyond the housing casing wall as the lower Querterrorismserbreiterung, despite contacting state able to touch the printed mostly and provided with indications of source cylindrical jacket wall of the container, eg in a shipping package, is avoided. . Finally, it is also advantageous that the squeezing piston, starting from a central, circumferential web, has two ring lips pointing up and down as sealing lips.
  • the cover has a sealing cone that sits on the end edge of the housing. So there are no leakage losses when pouring the initially liquid substance. Flying components cannot escape during later use.
  • the container-shaped container for deodorant sticks, lipsticks or the like consists of a sleeve-shaped housing 1. Its lower open end forms a standing edge 2. The other, open end forms the outlet opening 3. The latter is covered by a cap-like cover 4. It can be assigned in the detention center; in the exemplary embodiments shown, however, a screw assignment is selected.
  • the threaded section denoted by 5 leads to a certain reduction in cross-section of the otherwise constant wall thickness of the housing.
  • the wall section forming the threaded section 5 is slightly offset, so that one can speak of an even thinner section here.
  • the jacket wall W runs through at the same level. It is aligned with the thread tips.
  • the cylindrical housing widens towards the edge 2 while maintaining the wall thickness.
  • This section which extends approximately over a sixth of the length of the housing, takes, in a rotationally symmetrical manner, a continuously outward curved course B.
  • the relevant widening of the cross-section in this case corresponds to the dimension of the wall thickness and leads to a centering funnel 8 for an extrusion piston 9 to be inserted from this end, which sealingly leads to the cylindrical inner surface 1 'of the housing wall.
  • the ejection piston is moved with the finger and pushes the stiffly pasty mass, not shown in the drawings, forming a deodorant stick or lipstick in the direction of the outlet opening 3.
  • the mass is poured into the lid-closed housing from the stand edge 2, the centering funnel 8 also proving to be useful by expanding the filling opening in a cup-like manner.
  • the inner surface 1 'of the housing wall is roughened at least in the cylindrical region adjoining the curve course B.
  • the latter can be created by sandblasting.
  • a roughening can also be produced in terms of shape. This allows the air to pass through, but prevents the transfer of pasty mass.
  • the roughening area is designated by x and extends over a little more than a piston length in the cylindrical section near the bottom.
  • the cylindrical jacket wall of the cover collar 7 protrudes by an amount above the housing jacket wall W, like the lower cross-sectional widening. This has an advantageous effect in that close-fitting containers with their printable cylindrical section practically do not come into contact with one another, so that prints or other graphic jobs are not scratched. H. to be damaged. The product keeps its finish.
  • the inner surface of the cover 4 is concavely curved directly or indirectly. This surface bears the reference number 11.
  • the inner surface of the cover itself forms this arch surface 11; in the second embodiment (FIG. 2) it is formed by an insert 12.
  • a sealing ring 13 which is placed on the front edge 1 "of the sleeve-shaped housing 1 and in whose inner edge region on the housing side a spherically curved membrane is rooted.
  • the central apex Sch of this membrane extends at the same height as the upper ring end.
  • the inner surface is that Arch surface 11.
  • This upper ring end is supported on a horizontal ring shoulder 14 of the cover 4. Starting from this ring shoulder, the cover 4 itself takes on a curvature that is parallel to the membrane.
  • the insert 12 is held against loss due to the internal thread of the cover 4 projecting somewhat from the insert storage.
  • the insert 12 is made of a more seal-friendly, softer material, such as, for example, polyethylene.
  • FIG. 1 provides, instead of such a sealing insert 12, a measure that achieves the same goal in that the cover 4 forms a sealing cone 15 which is placed on the end edge 1 'of the housing 1.
  • the front edge 1 ' has a corresponding bevel there. This is 45 ° and recorded with respect to the front edge a little more than half the wall thickness there, so it extends slightly beyond the thread.
  • the Auspreßkolben all embodiments are hollow, so that one can speak of a pot shape.
  • the pot cavity points downwards, i.e. H. towards the footprint F of the container.
  • the pot cavity is closed by a plate 16.
  • This disk-shaped plate is assigned by means of the clip connection.
  • the pot edge has the corresponding clip nose 9 '. It can be a continuously ring-shaped nose or also individual web-like projections.
  • an additional measure in this regard is that the upper side of the hollow press-out piston 9 with its cup cavity pointing in the direction of the outlet opening 3 has an opening 21 with an opening edge 23 extending inwards over the piston wall 22.
  • This squeezing piston 9 otherwise only differs in technical details insofar as the ring lips 19 do not start from a common ring web 18, but are rooted separately in the piston wall 22.
  • the ring lips are set a little steeper there.
  • the opening 21 is formed by a disc which can be clipped to the edge of the cup-shaped piston and is essentially flat and conical, the edge of which is angled parallel to the piston wall 22 and carries a bead on the inside which cooperates with an annular groove in the piston edge.
  • the angled edge protrudes into the V-notch-like annular groove 20 between the annular lip 19 and the piston wall 22.
