Definitions

  • the invention relates to a dispenser with a cylindrical product container, with a piston to be displaced pneumatically from the container base in the cylinder axis direction to an outlet opening at the end of the container head, and a pressing means connected to a base opening of the container for pressurizing the pump space defined between the piston and the container base with compressed air.
  • a piston is moved within a cylinder in the direction of the outlet opening of the package by means of compressed air and product is thereby dispensed.
  • the associated product container consists of a deformable tube in which a piston-like element, the outer diameter of which is larger than the inner diameter of the tube, can be moved in the direction of the outlet opening by means of compressed air.
  • the compressed air is supplied with the aid of a bellows, so one-handed operation is not possible.
  • Another disadvantage of the dispenser is the extreme stress on the bottom-side welding or adhesive surfaces with the risk of tearing open, particularly during the first dispensing.
  • the known packaging cannot be completely emptied because the tube in its upper part adjacent to the outlet opening deforms less than in the rest of the body due to the transition in wall thickness to the tube shoulder is cash.
  • the discharge pressure required for dispensing higher-viscosity materials in connection with the friction of the piston element on the inner tube wall must be relatively high, so that the material used for the tube and the connection technology between the tube and the tube base make extremely high and sometimes contradicting requirements -are.
  • the invention has for its object to provide a dispenser packaging that can be operated with only one hand, allows the filling and processing of different viscous products and is still relatively inexpensive to manufacture compared to known dispensers.
  • the solution according to the invention for the dispenser mentioned at the beginning with pressing means connected to a bottom opening for pressurizing the pumping space between the piston and the container bottom with compressed air is that a bellows open at both longitudinal ends as pressing means with its front longitudinal end into the bottom opening of the cylindrical, essentially inflexible Container is fitted sealingly and has at its rear longitudinal end a valve opening to be closed during operation.
  • the valve opening is preferably to be kept pumped with a finger or the thumb of the actuating hand.
  • the dispenser according to the invention consists of only a few components, which can be produced as plug-in, snap-in or screw connections without complex welding or less durable bonding.
  • the dispenser can therefore be produced and assembled with relatively little effort.
  • the dosing with the dispenser according to the invention only requires the bellows to be pressed in while the valve is kept closed Opening conveniently at the same time with the operating finger or thumb. It is advantageous that the valve opening is released at the same time when the bellows is relaxed by lifting off the finger or thumb.
  • the dispenser can therefore be easily operated with one hand.
  • the container is made of non-flexible material, the residual emptying of the packaging is not a problem if only an adequate seal of the pump chamber on the container base and on the piston is ensured and the front end of the piston facing the product is adapted to the inside of the outlet opening of the container. Under this condition, even more viscous masses can be dosed without leaving any significant residual amounts in the container.
  • a guide sleeve slipped over the bellows is slidably mounted in the cylinder axis direction on the container bottom part adjacent to the container bottom.
  • the guide sleeve should have a bottom with an opening for the passage and coupling of a neck extension of the bellows surrounding the valve opening.
  • the bottom of the container is designed as a coupling part to be positively inserted into the lower end of the container, with outer sealing lips that press against the inner wall of the container when the pump chamber is pressurized and, on the other hand, inner sealing lips that engage the neck-shaped front longitudinal end of the bellows. Installation is particularly easy if the loading
  • the bottom of the container must be manufactured separately and inserted into the lower end of the container in a form-fitting manner, for example by snapping, snapping or screwing.
  • the container bottom has two circumferential sealing lips which, when the pump chamber is pressurized, bear against the inside wall of the container and the circumference of a neck of the bellows in order to seal the pump chamber.
  • all components can be designed to be essentially rotationally symmetrical and thus particularly economical to manufacture and assemble.
  • bellows are those components which oppose a restoring force in the longitudinal direction, that is to say they tend to expand in the longitudinal direction.
  • the length of the bellows is expediently chosen so that, on the one hand, there is a sufficient distance between the rear edge of the container bottom facing the bellows and the one for inserting a container base designed as a dome part to be positively inserted into the lower container end with a preassembled bellows part and guide sleeve Bottom facing front edge of the guide sleeve for attaching mounting elements remains and on the other hand the bellows is exposed to a certain preload in the fully assembled state between the cylindrical container and the guide sleeve. The preload should bring the guide sleeve back quickly after the pumping process.
  • the bottom of the container including any sealing lips should be made of a material, e.g. Medium-density polyethylene, which ensures an exact fit with little manufacturing and sufficient stability for highly viscous products.
  • the dispenser according to the embodiment of FIG. 1 consists of the following individual parts to be individually manufactured and to be coupled by plug-in, snap-in or screw connection: closure cap 1, applicator attachment 2, product container 3, piston 4, container base 5, bellows 6 and guide sleeve 7.
  • closure cap 1 closure cap 1
  • applicator attachment 2 product container 3
  • piston 4 container base 5
  • bellows 6 and guide sleeve 7.
  • the product container 3 is essentially prismatic or cylindrical and has a tapering outlet opening 8 with an attachment part 9 for the applicator attachment 2.
  • the product space 10 Inside the container, the product space 10, the piston 4, the pump chamber 11 and the container base 5 follow one another.
  • the bellows 6 If the bellows 6 is pressed simultaneously with the guide sleeve 7 when closing the rear valve opening 12 with the aid of the actuating finger or thumb in the longitudinal or axial direction 13, the resulting reduction in the interior of the bellows 6 must enlarge the pump chamber 11 and thus Pushing the piston 4 in direction 13 to the outlet opening 8 of the container 3 result. If the pressure is then removed from the guide sleeve 7 and at the same time the valve opening 12 is released, the bellows 6 can return to its original size tension so that the dispenser is ready to be dispensed again.
  • the product container 3 has a collar 15 on the outside at its bottom end 14 opposite the outlet opening 8 and sawtooth-shaped snap grooves 16 on the inside.
  • the container bottom 5 has an outwardly tapering circumferential sealing lip 17 and several sawtooth-shaped fastening ribs 18 which should correspond exactly with the snap grooves 16 of the product container 3.
  • the container base 5 has an inwardly inclined circumferential sealing lip 19 which sealingly nestles under a snap bead 21 provided on the neck part 20 of the bellows 6.
  • the valve opening 12 is located in a cylindrical, neck-shaped extension 22 with a snap bead 23 which is to be pressed in through a central bore 24 in the bottom 25 of the guide sleeve 7.
  • the guide sleeve 7 has at the front end 26 facing the product container 3 a plurality of internal retaining cams 27 which, after being assembled, abut with the product container 3 on the upper edge 28 of the collar 15 and prevent the guide sleeve 7 from being pulled out again.
  • the clear width of the retaining cams 27 attached to the circumference of the guide sleeve 7 should be such that an almost smooth displacement of the guide sleeve 7 on the outer diameter 29 of the product container 3 is possible.
  • the bellows 6 has a length L1 in the unassembled state, the size of which is so dimensioned that a certain distance 31 between the lower edge 30 of the container base 5 and the upper edge or the front end 26 of the guide sleeve 7 remains, which is sufficient for pressing the container base 5 into the lower base end 14 of the product container 3, possibly required assembly elements.
  • the bellows 6 is compressed to a shorter length L2.
  • the bellows 6 consists of a material with good resilience, such as medium-density polyethylene, a preload is generated in the structure described, which after actuation during metering leads the guide sleeve 7 back into the starting position, in which the holding cams 27 on the upper edge 28 of the federal government 15, withdraws or pushes.
  • the details of the container bottom designated 5 overall are clearly highlighted.
  • the shape and position of the circumferential sealing lips 17 and 19 are of essential importance for the sealing of the pump chamber 11, which is under air pressure during metering.
  • the tapering execution of the sealing lips 17 and 19 in the wall thickness towards the lip end as well as a slight preload in relation to the diameters to be sealed on the inside of the product container 3 and on the outside of the neck part 20 of the bellows 6, in connection with the prevailing in the pump chamber 11 during metering Overpressure a tight fit "of the free ends of the sealing lips 17, 19 to the surfaces to be sealed.
  • the inner circumferential web 32 of the container base 5 together with the stiffening ribs 33 substantially stabilize the outer profile to be pressed into the base end 14 of the product container 3.
  • a snap connection produced in this way between the container base 5 and the product container 3 is no longer deformable in this area when the dispenser packaging is used and represents a further favorable condition for the tightness and thus the intended function of the system.
  • FIG. 5 and 6 schematically indicate alternative assembly options for the dispenser according to the invention.
  • the product container 3 is filled from the open bottom end 14.
  • the parts 1 to 3 identified with the same reference numerals as previously are first combined to form the assembly 34, then the product container 3 is filled and closed with the piston 4. After preassembly of parts 5 to 7 to assembly 35, it is connected to assembly 34.
  • the product container 3 is filled via its neck or attachment part 9.
  • parts 3 and 4 are first preassembled to form assembly 36 and parts 5 to 7 again to assembly 35.
  • the modules 35 and 36 are combined to form the module 37. This is filled through the neck 9 of the product container 3 and then closed with the assembly 38 formed from parts 1 and 2.
