- 2. The device of claim 1, wherein said engaging member includes a projection extending radially inwardly from said barrel member into said passageway to create a frictional fit between said barrel member and said plunger member.
- 3. The device of claim 1, wherein said opening is encircled by said petals.
- 4. The device of claim 3, wherein said receptacle is defined by an interior surface of said distal end and is sized and shaped such that a pharmaceutical product received in said receptacle is in contact with said interior surface only at said tips.
- 5. The device of claim 4, wherein each of said petals is flexible such that said tips are expandable and contractible in a substantially radial direction.
- 6. The device of claim 5, wherein said petals are sized and shaped such that an approximately half of a pharmaceutical product received in said receptacle extends outwardly beyond said tips.
- 7. The device of claim 6, wherein each of said petals curves radially inwardly such that the curvature of each of said tips corresponds generally to the curvature of a substantially central portion of a pharmaceutical product received in said receptacle.
- 8. The device of claim 7, wherein said petals are sized and shaped so as to receive an oval-shaped suppository product.
- 9. The device of claim 1, wherein each of said petals has a length measured in said axial direction, said length being about one-half of an axial length of a pharmaceutical product received in said receptacle.
- 10. The device of claim 9, wherein each of said petals has a substantially semi-circular shape.
- 11. The device of claim 1, wherein said barrel member includes a proximal end, which is located opposite to said distal end, and a substantially annular wall, said passageway extending between said distal and proximal ends through said wall.
- 12. The device of claim 11, wherein said wall has a first thickness at said tips and a second thickness at said proximal end, said first thickness being substantially less than said second thickness.
- 13. The device of claim 12, wherein said barrel member has a proximal section adjacent said proximal end and a distal section adjacent said distal end, said distal section having a flared shape.
- 14. The device of claim 13, wherein said distal end has a first radius and said proximal end has a second radius, said first radius being greater than said second radius.
- 15. The device of claim 14, wherein said barrel member includes an intermediate section positioned between said proximal and distal ends, said distal section including a proximal end portion integrally connected to said intermediate section and a distal end portion defined by said distal end of said barrel member, said distal and proximal end portions having third and fourth radii, respectively, said third radius being greater than said fourth radius.
- 16. The device of claim 12, wherein said barrel member is tapered as it extends from said proximal end to said distal end.
- 17. The device of claim 16, wherein said distal and proximal ends have first and second radii, respectively, said first radius being less than said second radius.
- 18. The device of claim 1, wherein said plunger member has a distal end and a contact platform attached to said distal end of said plunger member for applying an axial force to a pharmaceutical product received in said receptacle.
- 19. The device of claim 18, wherein said contact platform has a size similar to the size of a pharmaceutical product received in said receptacle so as to substantially evenly distribute an axial force to a pharmaceutical product.
- 20. The device of claim 1, wherein said plunger member is axially movable relative to said barrel member between a first position, in which said contact platform is retracted into said receptacle so as to permit the loading of a pharmaceutical product in said receptacle, and a second position, in which said contact platform is positioned adjacent said tips so as to expel a pharmaceutical product from said receptacle.
- 21. The device of claim 20, wherein when said barrel member is positioned in its said first position, said contact platform is positioned in said receptacle and is in contact with a pharmaceutical product received in said receptacle so as to properly orient the pharmaceutical product such that said distal end of said barrel member is in contact with the pharmaceutical product only at said tips.
- 22. The device of claim 21, wherein said contact platform is positioned outwardly beyond said petals when said plunger member is positioned in its said second position.
- 23. The device of claim 21, wherein said contact platform is in engagement with said petals so as to flex said petals in a radially outward direction, when said plunger member is positioned in its said second position.
- 24. The device of claim 21, further comprising first restricting means for restricting said plunger member from moving beyond its said first position.
- 25. The device of claim 24, further comprising second restricting means for restricting said plunger member from moving beyond its said second position.
- 26. The device of claim 25, wherein said barrel member includes a distal section located adjacent said distal end of said barrel member and having a flared shape, said first restricting means including a portion formed as part of said distal section and sized and shaped so as to engage said contact platform.
- 27. The device of claim 25, wherein said first restricting means includes an annular rib extending radially inwardly from an annular wall of said barrel member into said passageway and positioned adjacent a proximal end of said barrel member, said first restricting means having a stop member formed on said plunger member and sized and shaped so as to engage said annular rib.
- 28. The device of claim 25, wherein said second restricting means includes a flange formed on a proximal end of said plunger member and sized and shaped so as to engage a proximal end of said barrel member.
- 29. In combination, a pharmaceutical product; a device for delivering said pharmaceutical product to a bodily cavity, said device including a barrel member and a plunger member, said barrel member having a distal end, which includes an opening, a plurality of petals, which extend outwardly from said distal end in a generally axial direction, and a passageway, which extends through said barrel member in a direction substantially parallel to said axial direction and which is in communication with said opening, said petals cooperating with said opening so as to form a receptacle, said pharmaceutical product being releasably received in said distal end of said barrel member, each of said petals having a truncated flexible tip sized and shaped so as to engage a substantially central portion of said pharmaceutical product such that a large section of said pharmaceutical product extends outwardly beyond said petals so as to facilitate the release of said pharmaceutical product from said receptacle, said plunger member movably extending through said passageway of said barrel member for releasing said pharmaceutical product, and said barrel member including an engaging member positioned in said passageway for engaging said barrel member; and packaging means for packaging said device together with said pharmaceutical product.
- 30. The combination of claim 29, wherein said packaging means includes a tray for receiving said device and said pharmaceutical product and a lid removably attached to said tray.
- 31. The combination of claim 30, wherein said tray is a blister-type tray.
