Definitions

  • the invention relates to a waist bottle according to the preamble of claim 1.
  • a waist bottle of this type is known from CH-PS 628 585.
  • the stopper is pressed out there via a rod that reaches its end on the bottle side in front of it.
  • the latter sits in an accessible manner in a bottle closure cap which is inserted into the neck of the waist bottle with a stopper projection.
  • This is secured with a metal capsule, which is left blank on the ceiling side in the center for the passage of a compressible bushing section projecting beyond the bottle cap top.
  • the bushing section is designed like a harmonica and frictionally engages the upper end section of the rod inserted into its cavity.
  • a pressure piece held at a distance from the compressible bushing section can be axially displaced in the direction of the stopper after release in a leading lower part.
  • the pressure piece is in bayonet slot connection to the named part.
  • Such an embodiment is not expensive to manufacture, but is also highly disadvantageous in use.
  • the use of special material is required to form the axially elastic or compressible bushing section.
  • the bar sits decentrally. This creates the risk of the plug tipping over, making it difficult to express it. After all, there is no exact rod alignment.
  • the object of the invention is to design a generic waist bottle in a technically simple, advantageous manner in such a way that, with less force, a tilt-free removal of the chamber-dividing stopper closure is achieved.
  • the use function of a generic waist bottle is significantly improved; above all, there is a completely tilt-free pressing of the stopper from its closed position, which separates the two components.
  • the structural means are simple and functional. The procedure is such that the rod and stopper are connected to each other, the screw cap bottle cap has a butt shoulder, which rests on the front end of the connecting rod in the basic position, and by an obliquely downward flank for adjusting or centering sliding of the front end of the connecting rod when applying the bottle cap.
  • the one-piece design mentioned is favorable, and also in terms of assembly and use technology. It cannot happen, as in the prior art, that the loose and thus uncontrolled plug washer blocks in the exit path.
  • the flanks of a frustoconical, the butt shoulder are pre-featured stored intermediate section of the bottle cap formed.
  • the intermediate section practically forms a funnel.
  • the flanks are formed by the top surfaces of individual cams of the connecting rod, onto which a collar of the closure cap, which protrudes above the butt shoulder, slides centering.
  • the connecting rod has a cross-shaped cross section.
  • the invention further proposes that in the pushed-out stopper position the outer flanks of the cross-section come to the waist ring inner surface in the adhesive seat position.
  • the cross section of the stopper forms a baffle which promotes distribution and mixing with regard to the component located in the bottle cap side.
  • the connecting rod is tubular with the plugs adjacent jacket wall openings, in the area of the pipe wall stops, which, when the plug is pushed out, are seated on the waist flank facing the bottle cap.
  • Such stops define the optimal residual displacement stroke with regard to the passage of the liquid and the evacuation of the displaced air in the lower space. It is also advantageous that the root region of the intermediate section comes into the sealing position with respect to the bottle neck. It also proves advantageous that the outer surface of the collar comes into the sealing position with the bottle neck.
  • the cams explained above, which are also useful in this context, can be dimensioned such that they exert a slight radially outward pressure on the collar, which favors the sealing contact of the corresponding ring wall surface. It is also advantageous that the root region of the intermediate section comes into the sealing position with respect to the bottle neck.
  • a sealing jacket surface adjoins the root area or the collar, the length of which is at least equal to the rest of the screwing on stroke of the bottle cap corresponds.
  • the abutting surface is formed by the end faces of the inside longitudinal ribs of the bottle cap. Such ribs stiffen the cap area there and also the collar in which they are partly rooted.
  • the head end of the sealing outer surface merges into an outward-facing seat ring surface, on which the lid of a removal opening of the bottle cap is seated, which is screwed onto a tube shoulder of the bottle cap that extends from the butt shoulder, which lid with a sealing ring engages in the pipe socket.
  • the waist bottle F created, for example, as a blown container forms a so-called two-component pack. For this purpose, it is divided into two rooms A and B of approximately the same volume. In the area of the wasp waist-like constriction, referred to as the waist level E-E, a stopper 1 separates the two rooms A and B. The constriction opening is in the center. Their diameter corresponds to about a third of the bottle diameter. The bottle length is about three times the bottle diameter.
  • the two spaces or the substances accommodated therein can be connected to one another by pushing the stopper 1 out of the region of the waist level E-E, which is done with the aid of a bottle cap 2.
  • the stopper 1 is in rod connection with the screw thread 3 having a bottle cap 2.
  • the plug is in one piece with the connecting rod 4.
  • the latter has a cross-shaped cross-section according to FIGS. 1, 2 and 5.
  • the outer flanks 4 In the pushed-out stopper position (cf. FIG. 2), the outer flanks 4 funnel of the cross-section come into an adherent position to the waist ring inner surface 5.
  • the stopper 1 projects freely into space B.
  • the connecting rod 4 consists of a tubular component.
  • the tubular connecting rod 4 forms jacket wall openings 6 for the passage of the bottle cap component.
  • the latter are formed by longitudinal webs 7, the openings of which remain through their angular spacing.
  • this configuration can also be referred to as a cross-shaped configuration, since four such webs 7 are formed on the inside of the tubular connecting rod 4 are.
  • the lower web ends are rooted in the top of the plug 1; the upper ends are connected on the inside at the end of the pipe.
  • the free-stretched webs bring the most favorable usable flexibility with regard to the adhesive seat position that has been implemented to the waist ring inner surface 5, which interacts with the outer flanks 4 ⁇ of the webs 7.
  • the webs 7 are formed with stops 8 extending in the plane of the tube wall.
  • the stops 8 define the end position of the plug pushed out, as can be seen in FIG. 4.
  • the lower end of the stops 8 meets the waist flank 9 facing the bottle cap 2.
  • a corresponding stop limitation can also be realized by shaping such stops on the outer flanks 4 ⁇ of the cross section.
  • the stopper 1 is pot-shaped with a pot cavity directed into the lower space B.
  • the outer edge of the pot is chamfered, in the interest of centering the stopper in addition to the centering to be gained from the waist flank.
  • the other end of the connecting rod 4 interacts with a butt shoulder St of the bottle cap 2.
  • the butt shoulder St lies on the free end 4 ⁇ of the connecting rod 4.
  • This connecting rod 4 is also centered in this region.
  • the bottle cap 2 forms an obliquely outward and downward flank 10 for this purpose Adjusting or centering sliding of the front end 4 ⁇ of the connecting rod 4 when the bottle cap 2 is applied.
  • the flank 10 is formed by a truncated cone-shaped, forming a catch funnel, the intermediate shoulder 11 upstream of the butt shoulder St of the bottle cap.
  • Top of the Butt shoulder St the intermediate section 11 continues into a central, conically tapering mouthpiece 12, which projects over the top of the bottle cap 2 by about half its height.
  • the mouthpiece opening 12 is closed by a closure piece 13 connected via a predetermined breaking point. This can simply be pulled off to dispense the mixture and, for this purpose, have an enlarged face (not shown).
  • the root region 14 of the intermediate section 11 formed by a neck-in retraction of the bottle closure cap 2 already comes into a partial unscrewing position of this closure cap in the sealing position with respect to the inner surface of the bottle neck 15.
  • the root region 14, which extends cylindrically up to the ceiling of the bottle closure cap 2 also forms with its remainder Wall section a sealing surface 14 ⁇ . Their length corresponds at least to the remaining screw-on stroke y of this bottle cap 2.
  • this is formed there by a cylindrical collar 15 molded onto the top of the bottle cap 2.
  • the bluntly designed mouthpiece 12 is rooted in the transition area between the ceiling and said collar 16. It runs concentrically to the closure cap wall and extends only over a partial height of the same (about a third).
  • this variant also results in a slight modification compared to the previously described variant, to the extent that the abutting surface St now faces the downward-facing end faces which are oriented perpendicular to the longitudinal central axis xx of the waist bottle F.
  • formed on the inside of the bottle cap is formed longitudinal ribs 17.
  • a total of four such longitudinal ribs 17 are taken into account. They extend at the same angular distance from each other, are rooted on the inside of the collar 16 on the one hand and on the other hand extend above into the area of the mouthpiece 12. The corresponding ribbing going in depth stabilizes the relevant zone.
  • the end faces of the longitudinal ribs 17 end at a distance from the collar end facing the space A that there is still a sufficient axial overlap area between the collar 16 and the connecting rod 4.
  • the overlap zone lies at the level of the retracted end section of the bottle neck which forms the actual sealing surface.
  • This zone is used here for centering in accordance with the function of the edge 10 according to FIG. 1.
  • flanks 10 are formed by correspondingly beveled head surfaces of individual cams 18 of the tubular connecting rod 4 here. These also act as spacers cams 18 sit on the outer surface of the connecting rod 4; they are at the same angle and are arranged in a four. When the bottle cap 2 is screwed together, the section of the collar 17 projecting over the shoulder St slides onto the upper end 4 ⁇ of the connecting rod 4. Passage gaps remain between the cams 18.
  • a horizontal ring rib 20 is formed on the outside of the bottle neck 15, for example in the back of its sealing surface. The latter thus extends in the end region of the bottle neck and acts with a counter rib 21 the inner wall of the bottle cap 2 together. The counter rib 21 jumps over the ring rib 20 at the beginning of the screw contact.
  • FIGS. 1 and 3 i.e. a storage position in which the bottle cap 2 is unscrewed against a clear resistance or even on steeper flanks is no longer possible. In this position there is already a complete sealing of the space A from the outside and the centering of the connecting rod 4 has already taken place.
  • the remaining screw-on stroke y is, however, chosen to be approximately twice the plug seat dimension z.
  • a relatively firm plug seat which is always desirable for safety reasons, has to be overcome, the opening movement is nevertheless easy to handle due to the relatively flat thread increase.
  • the edge of the cap 22 can strike a shoulder 23 achieved by wall offset in the central region of space A. Overlapping or instead, however, it is also possible to have the front edge of the bottle neck tread against the inside of the lid of the bottle cap for the relevant end limitation.
  • the connecting rod 4 adjoining the top of the stopper 1 can also be so far behind be cut so that there is no clamp seat holder, so that the connecting rod 4 falls into the lower space B.
  • Fig. 6 shows this free cut of the connecting rod shaft. Otherwise, the same structure is chosen as described for FIGS. 1 and 2.
  • the bottle cap 2 shown in isolation in FIG. 7 differs, however, insofar as the mouthpiece 12 can be sealed again there. If there is agreement, the reference numbers are used accordingly.
  • the further details consist in the fact that the head end of the sealing jacket surface merges into an outwardly directed ring seat surface 24, on which the edge of a screw-on cover 25 closing the removal opening 12 'of the mouthpiece 12 is placed. Its internal thread bears the reference numeral 26.
  • the corresponding external thread 27 ⁇ is located on a cylindrical tube extension 27 of the bottle closure cap 2 starting from the butt shoulder St.
  • a sealing ring 28 extends from the inside of the lid 25 and engages in the removal opening 12 ⁇ .
  • the external thread 27 ⁇ extends over the entire length of the tube extension 27.
  • the latter has a material-saving effect and, due to the ripe-like wrap, nevertheless provides a high degree of use stability.
