Definitions

  • the invention relates to a method of producing a sprayer comprising a manually operated pump whose pump body, made of flexible plastic material, forms a stopper forcing itself into the mouth of a bottle; it relates more particularly to an improvement of the bottle when it is plastic.
  • a preferred field of application of invention is that of miniature sprayers dispensed as samples of liquid products, including perfumes.
  • the document US 2002/179649 describes a dispenser comprising three parts, a bottle, a fixing ring and a pump body. However, the ring is pre-assembled on the body before mounting on the neck of the bottle.
  • a manually operated pump provided with a sprayer button whose pump body can be deformed slightly to form a stopper forcing into the mouth of a bottle, as described in US 6,073,805 .
  • the bottle may be plastic.
  • the inner surface of the mouthpiece is as smooth as possible for reasons of sealing performance.
  • the bottle is often in the form of a small cylinder.
  • the internal volume of the bottle is also cylindrical and the mouth is not distinguishable from the rest of the bottle.
  • the invention relates to a method of making a sprayer as described in claim 1.
  • the aforementioned hooking rib is preferably defined in the immediate vicinity of the orifice of said mouthpiece, which facilitates demolding of the bottle. More particularly, the attachment rib is defined by a restriction of the mouth in the immediate vicinity of the orifice of it. Most often, the attachment rib will be defined by a wall thickness in the vicinity of said orifice.
  • the structure defined above is well suited to the injection molding of the bottle.
  • the mold comprises a cylindrical matrix inside which engages a core itself generally cylindrical but having an annular undercut area, capable of defining the aforementioned wall thickness, in the vicinity of the orifice of the 'mouth. Demolding takes place forcefully through an ejection ring sliding on the core, when it is removed from the matrix, driving the bottle that has just been molded.
  • the miniature sprayer 11 shown on the Figures 1 and 2 consists essentially of a pump 12 with manual operation and an externally cylindrical bottle 14.
  • the pump 12 is of a known type comprising a pump body 16 made of soft, deformable plastic, a suction tube 18 and an outlet tube 19 on which a pushbutton (not shown) fitted with spray means.
  • the pump body 16 comprises a crank 20 coming to be applied around the orifice 22 of the mouth 24 of the bottle.
  • the portion of the pump body more particularly constituting a plug 26 is cylindrical and has a diameter substantially equal to the inside diameter d of the bottle.
  • the latter for reasons of simplicity of embodiment, has an essentially cylindrical interior cavity 25.
  • the mouth 24 intended to receive the cap portion 26 of the pump body is not distinguishable from the rest of the bottle, the diameters being the same.
  • the bottle is integrally molded plastic, one piece.
  • the mouth 24 has internally a ringing rib 28, coming from molding.
  • the plastic material constituting the bottle 14 is harder and more rigid than that which forms the pump body 16 or at least the plug portion 26 thereof, so that said hooking rib 28 is embedded in the pump body, with a slight creep of the plastic material constituting the latter, as can be seen on the figure 2 .
  • the pump body 16 on the one hand and the bottle 14 on the other hand can be made of polyolefins of different grades. A soft grade is chosen for the pump body and a rigid grade for the bottle.
  • the hooking rib 28 is defined in the immediate vicinity of the orifice 22 and protrudes internally relative to the remainder of the cylindrical surface of the mouthpiece. It is defined by a diameter restriction in the immediate vicinity of the orifice of said mouth.
  • the fastening rib is defined by a wall thickness in the mouth, in the vicinity of the orifice of the bottle.
  • the Figures 3 to 7 illustrate the injection molding process of the bottle.
  • the mold 30 consists of a perfectly cylindrical matrix 32 (at the bottom of which opens the plastic injection orifice) and a substantially cylindrical core 36 but having an undercut area 38 constituted here by a simple annular groove which is positioned next to the orifice 40 of the matrix 32 when the core is in position.
  • a demolding ring 42 is slidably mounted on the core and closes the orifice of the die. In this position illustrated on the figure 4 it is clear that the volume of the bottle is defined between the matrix and the nucleus.
  • the core After injection of the plastic material ( figure 5 ) and start of cooling, the core is removed from the matrix and because of the undercut, the vial remains attached to the nucleus ( figure 6 ). Relative movement between the release ring 42 and the core 36 allows the bottle 14 to be forced out by sliding it along the core.
  • the mouth of the bottle expands slightly by the simple elasticity of the plastic material.
