Multi-chamber container and cap therefor
View Patent ↗A dispenser comprises a housing that has a removable tamper proof protective cap and tamper proof ring and is threaded to a container. The container, which is the main package, holds the supplemental component. The housing holds the first component into a plunger type chamber in a fully retracted position and is sealed from the supplemental component. The chamber has a delivery end that is closed before use. When pushed all the way in, the chamber's delivery end becomes open and delivers the first component into the main package.
1. A method of manufacturing parts of a cap, comprising:
manufacturing a cap body, the cap body being of one piece construction and including a bore;
manufacturing a plunger, the plunger being of a rigid construction and including a hollow portion, a lid forming a closed end and an open end; the plunger and lid being formed of one piece;
the plunger and cap body being manufactured so that the plunger is capable of being moved within the bore of the cap body between a first position and a second position, and the plunger is adaptable to form, with the cap body, at least a portion of a chamber to receive at least one component so that an open end of the plunger can be located in the chamber;
manufacturing a dispensing tip capable of being associated with a lower portion of the cap body and forming a closed end at a lower portion of the bore to form a seal resistant to passage of air and moisture with the cap body; and
the dispensing tip including apertures, and the dispensing tip being adaptable to be movable to an open position breaking the seal so that the at least one component can flow through the apertures.
2. The method according to claim 1 , wherein the apertures are spaced around a periphery of the dispensing tip.
3. The method according to claim 2 , wherein the dispensing tip includes a transverse base member comprising a generally conical shaped surface.
4. The method according to claim 1 , wherein the dispensing tip includes a transverse base member comprising a generally conical shaped surface.
5. The method according to 1 , wherein the apertures are located at a periphery of the dispensing tip so that the at least one component flows outwardly from the chamber.
6. The method according to claim 1 , wherein the plunger and the cap body include locking elements to maintain the plunger in the first position, and permit movement of the plunger to the second position.
7. The method according to claim 6 , wherein the locking elements restrict movement of the plunger in a direction that permits separation of the cap body and the plunger.
8. The method according to claim 6 , wherein the locking elements comprise flange and groove elements.
9. The method according to claim 5 , wherein the plunger includes a wall surrounding the hollow portion, and the wall contacts the periphery of the dispensing tip to break the seal.
10. The method according to claim 1 , wherein the dispensing tip is formed of a polymer material.
11. A method of assembling parts of a cap, comprising:
assembling a cap body, a plunger and a dispenser tip;
the cap body being of one piece construction and including a bore;
the plunger being of a rigid construction and including a hollow portion, a lid forming a closed end and an open end; the plunger and lid being formed of one piece;
assembling the plunger and cap body so that the plunger is capable of being moved within the bore of the cap between a first position and a second position, and the plunger forms with the cap body, at least a portion of a chamber to receive at least one component so that an open end of the plunger can be located in the chamber; and
assembling the dispensing tip with the cap body, the dispensing tip including apertures and being assembled with the cap body so that the dispensing tip is associated with a lower portion of the cap body and forms a closed end at a lower portion of the bore to form a seal resistant to passage of air and moisture with the cap body, and the dispensing tip is movable to an open position breaking the seal so that the at least one component can flow through the apertures.
12. The method according to 11 , wherein the apertures are located at a periphery of the dispensing tip so that the at least one component flows outwardly from the chamber.
13. The method according to claim 12 , wherein the plunger includes a wall surrounding the hollow portion, and the wall contacts the periphery of the dispensing tip to break the seal.
14. The method according to claim 11 , wherein the plunger and the cap body include locking elements to maintain the plunger in the first position, and permit movement of the plunger to the second position.
15. The method according to claim 14 , wherein the locking elements restrict movement of the plunger in a direction that permits separation of the cap body and the plunger.
16. The method according to claim 14 , wherein the locking elements comprise flange and groove elements.
17. The method according to claim 11 further including filling the chamber with the at least one component.
18. A method of manufacturing parts of a cap, comprising:
manufacturing a cap body, the cap body being of one piece construction and including a bore;
manufacturing a plunger, the plunger being of a rigid construction and including a hollow portion, a lid forming a closed end and an open end; the plunger and lid being formed of one piece;
the plunger and cap body being manufactured so that the plunger is capable of being moved within the bore of the cap body between a first position and a second position, and the plunger is adaptable to form, with the cap body, at least a portion of a chamber to receive at least one component so that an open end of the plunger can be located in the chamber;
manufacturing a dispensing tip capable of being associated with a lower portion of the cap body and forming a closed end at a lower portion of the bore to form a seal resistant to passage of air and moisture with the cap body, and the dispensing tip being adaptable to be movable to the second position breaking the seal so that the at least one component can flow from the chamber; and
manufacturing a tear strip which is capable of providing a compression barrier in order to maintain the lid in the first position and providing tamper evidence by providing a visible indication once the tear strip is removed.
19. A method of assembling parts of a cap, comprising:
assembling a cap body, a plunger, a dispenser tip and a tear strip;
the cap body being of one piece construction and including a bore;
the plunger being of a rigid construction and including a hollow portion, a lid forming a closed end and an open end; the plunger and lid being formed of one piece;
assembling the plunger and cap body so that the plunger is capable of being moved within the bore of the cap between a first position and a second position, and the plunger forms with the cap body, at least a portion of a chamber to receive at least one component so that an open end of the plunger can be located in the chamber; and
assembling the dispensing tip with the cap body so that the dispensing tip is associated with a lower portion of the cap body and forms a closed end at a lower portion of the bore to form a seal resistant to passage of air and moisture with the cap body, and the dispensing tip is movable to the second position breaking the seal so that the at least one component can flow from the chamber; and
