Definitions

  • the invention generally relates to a dispenser of a flow- able substance and, in particular, the invention relates to a fluid dispenser having a sealed chamber for holding fluid and a cavity for holding the fluid upon opening of the chamber.
  • a fluid dispenser having a sealed chamber for holding fluid and a cavity for holding the fluid upon opening of the chamber.
  • An object of the invention is to dispense a fluid from a dispenser without spilling any of the fluid.
  • Another object of the invention is to provide a fluid dispenser which can contain an ophthalmic medical solution and which can be used to directly dispense solution droplets into the sensitive areas of the body such as an eye.
  • This dispenser has a peripheral wall with an elongate axis, a first closed end wall portion, a second end wall portion axially spaced from the first end wall por- tion, a rupturable partition wall disposed axially between the first end wall and the second end wall forming a sealed cha - ber containing fluid adjacent to the first closed end wall and forming a dispensing cavity adjacent to the second end wall.
  • Figure 1 is a cutaway elevation view of a fluid dispenser according to the present invention
  • Figure 2 is a plan view as taken along the line 2-2 of Figure 1
  • Figure 3 is a section view as taken along the line 3-3 of Figure 1
  • Figure 4 is a cutaway elevation view of a second embodi- ment of a fluid dispenser according to the present invention
  • Figure 5 is a section view as taken along the line 5-5 of Figure 4
  • Figure 6 is a cutaway elevation view of a second embodi- ment of a fluid dispenser according to the present invention.
  • Figure 7 is a top view of a third fluid dispenser accord- ing to the present invention
  • Figure 8 is a side elevation of the dispenser shown in Figure 7.
  • Figure 9 is a side elevation of the dispenser shown in Figure 7 taken along lines 9-9.
  • a fluid dispenser or first embodiment or dispenser or ampoule 10 is provided.
  • Dispenser 10 has a peripheral wall 12 which has a closed end wall 14 and which has an open end wall portion 16.
  • Peripheral wall 12 has an elongate axis 18, a radially outer surface 20, and a radially inner surface 22.
  • Peripheral wall 12 has an intermediate partition wall 24, which separates a sealed chamber 26 from an open cavity 28. Chamber 26 contains a material, such as a fluid or a medical solution 30.
  • wall 12 is made of a transparent, flexible plastic material.
  • Closed end wall 14 has a crimped, closed, end wall portion or fin seal 32.
  • Partition wall 24 is disposed transverse to axis 18 and is axially disposed between end wall portions 14, 16.
  • Partition wall 24 has a relatively weak center portion 34 which has a relatively thin or reduced thickness for ease of breaking through wall 24 by fluid pressure, in order to allow fluid 30 to pass from chamber 26 to cavity 28.
  • a user applies a selective amount of finger pressure or opposite radial inward forces on peripheral wall 12 adjacent to partition wall 24 and chamber 26. Central portion 32 will then break or crack open due to the radially inward forces and fluid pressure. Fluid 30 then passes through partition wall 24 from chamber 26 to cavity 28.
  • An applicator (not shown) can be used to remove fluid 30 from cavity 28.
  • Dispenser 10a has a peripheral wall 12a, a closed end wall 14a and a second end wall portion 16a.
  • Peripheral wall 12a has an axis 18a, a radially outer surface 20a, and a radially inner surface 22a.
  • Peripheral wall 12a has an intermediate partition wall 24a, which separates a sealed chamber 26a from a cavity 28a. Cha - ber 26a contains a fluid 30a.
  • End wall 14a has a fin seal 32a.
  • Partition wall 24a has a relatively weak center portion 34a.
  • Open end wall 16a supports and receives an applicator or swab 40.
  • Swab 40 contacts fluid 30a when fluid 30a is dis- posed in cavity 28a, after center portion 34a is broken open.
  • Swab 40 has an underside application contact surface 42.
  • Swab 40 is made of cotton or the like.
  • the dispenser is preferably approximately 3/8 inch in diameter and approximately 2 inches long. In operation, fluid 30a passes into cavity 28a upon breaking center portion 34a. Dispenser 10a is held upside down and is squeezed until the swab surface 42 is wet. Then, dispenser 10a is held in a vertical position with swab 40 pointed upwardly. Swab 40 is then removed from cavity 28a for applying the portion of fluid 30a disposed on swab surface 42.
  • swab 40 can be made of a material of relatively large porosity for passing droplets through the swab by grav- ity and for dispensing droplets from its exterior surface.
  • a third embodiment 10b is provided. Parts of embodiment 10b which correspond to parts of embodi- ment 10 have the same numerals, but with a subscript "b" added thereto.
  • Dispenser 10b has a peripheral wall 12b, a closed end wall 14b and a second end wall portion 16b.
  • Peripheral wall 12b has an axis 18b, a radially outer surface 20b, and a radially inner surface 22b.
  • Peripheral wall 12b has a parti- tion wall 24b, which separates a sealed chamber 26b from a cavity 28b. Chamber 26b contains a fluid 30b.
  • End wall 14b has a fin seal 32b.
  • Partition wall 24b has a relatively weak center portion 34b.
  • the end wall portion 16b supports a drop- per tip or cap 50.
  • Cap 50 has an elongate spout 52 with a passageway 54 for dispensing droplets of fluid 30b.
  • Cap 50 has a cup-like portion 56 which overlaps part of outer surface 20b at end wall portion 16b. In operation, fluid 30b passes into cavity 28b upon breaking center portion 34b.
  • Dispenser 10b is held with cap directed downwardly, so that cap 50 dispenses droplets of fluid 30b.
  • a third type of dispenser which has a housing 60 which contains a fluid receiv- ing chamber 70, a foam applicator pad base 62 and a plastic container 64 for holding fluid.
  • the container 64 has a remov- able cap 68 at one end which allows ease of filing. The cap can be removed, the liquid placed in the container and the cap 68 reinserted. The cap must fit tight enough to remain leak proof when the container is squeezed.
  • the container has one or more plastic discs 66 representing a point of lower resist- ance of the container which will rupture when pressure is applied to the container. By squeezing the container, it causes the disc to break away because of the thickness of the plastic of the container wall at the place where the disc is located.
  • the thickness of the wall of the container can be 0.005 inches, whereas the thickness under the disc can be 0.002 inches.
  • the disc can be any size but it is preferred that the disc be of a size to just cover the area of decreased thickness in the wall of the container. A size of about 0.3 inches to about 0.5 inches in diameter is preferred, with a range of 0.2 inches to 1.0 inch being useful.
  • the housing 60 is elongated and spaced apart from the foam applicator 62.
  • the foam applicator can be made of any natural or synthetic material such as cellulose, polyethylene, polyvinyl chloride and the like.
  • Embodiments 10, 10a, 10b can contain and dispense an ophthalmic solution or medication and can be made of flexible plastic material, so that a user is more comfortable using plastic dispenser 10 than using a prior art glass dispenser or dropper.
  • Embodiments 10, 10a, 10b dispense a medicinal fluid 30 directly into the eye or wound or the like.
  • Swab 40 of embodiment 10a which has a relatively large application surface 42 on the underside thereof, is protected from toxic or undesirable substances in the air.
  • Swab 40 can be used to dispense droplets, or can be used to rub over a selective surface.
