Abstract

In one embodiment there is provided a closed non-refillable dispenser having a bottle configured to hold a liquid with a neck surrounding an opening for access to the liquid, and having a pump assembly fitted to the neck to manually pump liquid out of the bottle. The dispenser further having a closure cap fitted over the neck of the bottle and having a central closure opening to receive the pump assembly and a collar seated entirely over the closure cap. The collar and closure cap have corresponding engaging means configured to tighten the closure cap onto the neck when the collar is rotated clockwise and the collar being further configured to not engage the closure cap when the collar is rotated counter-clockwise, such that the closure cap is non-removably affixed to the bottle, thereby preventing the bottle from being refillable.

First claim

We claim:

1. A closed non-refillable dispenser comprising:
a bottle configured to hold a liquid and having a neck with a thread portion, the neck further surrounding an opening for access to the liquid;
a pump assembly fitted to the neck of the bottle and configured to manually pump liquid out of the bottle;
a closure cap fitted over the neck of the bottle and having a central closure opening to receive the pump assembly; and
a collar seated entirely over the closure cap, the collar and the closure cap have corresponding engaging means configured to tighten the closure cap onto the neck when the collar is rotated in a clockwise direction and the collar being further configured to not engage the closure cap when the collar is rotated in a counter-clockwise direction such that the closure cap is non-removably affixed to the bottle, thereby preventing the bottle from being refillable, and wherein the top ledge of the closure cap further includes:
a plurality of ramps, each ramp has an entrance portion that is substantially flush with a surface area of the top ledge, each ramp is defined as an arcuate segmented ramp that extends in a counterclockwise direction about the top ledge and increases in height from the entrance portion to a terminus end, and wherein each ramp is defined as having a pair of legs separately increasing in height from the entrance portion and extending in arcuate segments around the top edge to a segment that joins the two legs at the terminus end.

2. The dispenser of claim 1 , wherein the closure cap includes:
a top ledge having an inner terminal edge configured to define the central closure opening, the top ledge further having an outer terminal edge;
a side wall extends downwardly from the outer terminal edge to a lower edge; and
an annular flange extends outwardly from the lower edge of the side wall.

3. The dispenser of claim 2 , wherein the side wall of the closure cap is further defined to have an upper side wall section and a lower side wall projection section that is projected outwardly by a lip from the upper side wall section.

4. The dispenser of claim 2 further including an inner skirt extending downwardly from the inner terminal edge of the top ledge to define an interior channel between the inner skirt and the side wall, the interior channel configured to capture a portion of the neck of the bottle.

5. The dispenser of claim 4 further includes mating threads on an interior surface of the side wall and on an exterior surface of the neck of the bottle.

6. The dispenser of claim 1 , wherein the terminus end of each ramp is approximately 1.5 mm in height from the top ledge.

7. The dispenser of claim 1 , wherein each ramp extends around the top ledge for about 100 degrees.

8. The dispenser of claim 1 , wherein each ramp has a pitch defined as: 5.4 mm pitch/revolution.

9. The dispenser of claim 1 , wherein each ramp has a helix angle of 2.89 degrees.

10. The dispenser of claim 1 , wherein the collar includes:
a collar top with an inside terminal edge to define a collar opening configured to fit around a portion of the pump assembly over the central closure opening of the closure cap;
a shoulder section extends from the collar top to a downwardly extending collar wall,
a bottom collar retaining edge inwardly protruding from a lower interior surface defined about the collar wall; and
a plurality of interior cap protrusions extending inwardly from an upper interior surface defined about the collar top and shoulder section, wherein each of the ramps has a corresponding interior cap protrusion, and wherein when the collar is pressed downwardly towards the closure cap and rotated in the clockwise direction the cap protrusions engage the terminus ends of the ramps such that the closure cap rotates clockwise to tighten about the bottle, but when the collar is rotated in a counterclockwise direction the collar slips over the ramps preventing rotation of the closure cap in a counterclockwise direction, thereby defining a closure cap that is non-removably affixed to the bottle.

11. The dispenser of claim 10 , wherein each of the cap protrusions includes a secondary protrusion member extending along an interior surface portion of the shoulder section, and wherein the secondary protrusion members are defined to position against an upper section of the side wall to center the closure cap around the neck.

12. The dispenser of claim 10 , wherein the protruding bottom collar retaining edge extends inwardly to define a snap over fit engagement with the annular flange of the lower edge of the side wall such that the collar is non-removable from the closure cap.

13. A non-removable closure cap assembly for use with a non-refillable dispens herein the non-refillable dispenser includes a bottle configured to hold a liquid and having a neck with a thread portion, the neck further surrounding an opening for access to the liquid, and the non-refillable dispenser further includes a pump assembly fitted to the neck of the bottle and configured to manually pump liquid out of the bottle, the non-removable closure cap assembly comprising:
a closure cap fitted over the neck of the bottle and having a central closure opening to receive the pump assembly; and
a collar seated entirely over the closure cap, the collar and the closure cap have corresponding engaging means configured to tighten the closure cap onto the neck when the collar is rotated in a clockwise direction and the collar being further configured to not engage the closure cap when the collar is rotated in a counter-clockwise direction such that the closure cap is non-removably affixed to the bottle, thereby preventing the bottle from being refillable; and wherein the closure cap is defined to include:
a top ledge having an inner terminal edge configured to define the central closure opening, the top ledge further having an outer terminal edge, the top ledge further having a plurality of ramps, each ramp has an entrance portion that is substantially flush with a surface area of the top ledge, each ramp is defined as an arcuate segmented ramp that extends in a counterclockwise direction about the top ledge and increases in height from the entrance portion to a terminus end,
a side wall extends downwardly from the outer terminal edge to a lower edge,
an annular flange extends outwardly from the lower edge of the side wall, and
an inner skirt extending downwardly from the inner terminal edge of the top ledge to define an interior channel between the inner skirt and the side wall, the interior channel configured to capture a portion of the neck of the bottle, and wherein each ramp is defined as having a pair of legs separately increasing in height from the entrance portion and extending in arcuate segments around the top edge to a segment that joins the two legs at the terminus end.

14. The non-removable closure cap assembly of claim 13 , wherein the collar includes:
a collar top with an inside terminal edge to define a collar opening configured to fit around a portion of the pump assembly over the central closure opening of the closure cap;
a shoulder section extends from the collar top to a downwardly extending collar wall,
a bottom collar retaining edge inwardly protruding from a lower interior surface defined about the collar wall; and
a plurality of interior cap protrusions extending inwardly from an upper interior surface defined about the collar top and shoulder section, wherein each of the ramps has a corresponding interior cap protrusion, and wherein when the collar is pressed downwardly towards the closure cap and rotated in the clockwise direction the cap
