Definitions

  • This invention relates to a self-sealing applicator for dispensing fluids and, more particularly, to an applicator of this type which is especially useful for applying fluids that have a significant viscosity (e.g. lotion or cream products).
  • a significant viscosity e.g. lotion or cream products
  • Dispensing containers for dispensing viscous liquids including lotions and creams are known in the prior art. Some typical examples that may be mentioned that are somewhat related to the present invention are the dispensers shown in U.S. Patents 3,010,138 and 2,942,762. These are cnaracterized generally by the fact that they have an applicator element hereinafter referred to as applicator which comprises a transverse member provided with vertically extending slits through which the contents of the container may be expressed and applied to a surface.
  • Applicators of the type shown in the aforesaid prior art have at least two disadvantages. In the first place, these applicators are not self-sealing. Consequently, after application of the product, they are inclined to leak, particularly wnen the container is maintained in a position in which the opening in the applicator faces somewhat downwardly.
  • a second difficulty with such applicators is that they are too flexible and readily deformed or collapsed when applied to a surface. Tnis makes it oifficult to maintain the arcuate or curved shape of the applicator which is important particularly when the applicator is employed in a lotion or cream product that is to be applied to the armpit.
  • an improved self-sealing applicator may be provided if the applicator contains one or more dispensing slits which are cut through its arcuate applying surface at an angle with respect to the perpendicular to the tangent of said arcuate surface at the slit point.
  • tne improved applicator has an applicator head made of material that is sufficiently resilient to allow product to be dispensed through the slits provided for therein when pressure is applied to such product and yet stiff enough so that when combined with the proper thickness and surface curvature will not deform under normal application of force.
  • the applicator of tne present invention can be employed in conjunction with a variety of containers designed to apply pressure to a fluid product in order to dispense the product from the container.
  • a so-called squeeze bottle or squeeze container it will be described in conjunction with a so-called squeeze bottle or squeeze container.
  • Tnis comprises a flexible squeeze bottle 3 and an applicator 5 fitted over the open end of squeeze bottle 3.
  • Applicator 5 comprises a domed shape applicator head 7 and a depending skirt 9. Skirt 9 is provided with a collar 10 which is designed so as to form a friction fit with the neck 11 of squeeze bottle 3.
  • Application head 7 is designed so that it may be snapped on to a collar 10 that engages neck 11 of squeeze bottle 3.
  • collar 10 and applicator head 7 may be molded as a unitary piece from a suitable flexible material described in more detail below.
  • applicator head 7 is dome shaped or arcuate in outline.
  • the curvature and dimension of the applicator head are preferably chosen to conveniently accommodate the armpit of an average adult.
  • the dimensions of tne dome snaped applicator head 7 may vary somewnat. Usually, it will have an overall outside diameter in the range of from about 1 incn to about 3 inches with the preferred range being from about 1 1/2 inches to aDout 1 2/2 inches; that is to say that the outside diameter of the circle formed by the lower margin of the extremities of dome snaped applicator head 7 preferably has the aforesaid dimensions.
  • the radius of curvature of the arcuate applicator head 7 may also vary over a range. Ordinarily, however, this will fall within the range of from about 3/4 inch to about 2 1/2 inches inclusive, with the preferred range being from a D out 1 inch to about 2 inches.
  • applicator head 7 is designed so that its surface curvature will not deform under normal application of force.
  • the thickness of the material constituting the applicator head 7 is selected so and to oe within tne range of about 0.020 inches to about 0.050 inches and optionally witnin the range of from about 0.025 inches to about 0.040 inches.
  • Tne material used in fabricating applicator head 7 is such that it is sufficiently resilient to allow product to flow through angular slits provided for therein and yet will not be deformed under normal application of force.
  • materials are known in the prior art which meet these criteria. By way of example, the following may be mentioned: low density polyethylene, linear low density polyethylene, high density polyethylene, etc. However, the materials of choice are low density polyethylene or linear low density polyethylene. Materials of this cnaracter are marketed under the trade designations Alathon 20 and Dowlex 2552.
  • An essential feature of the present invention is provision of a dispensing slit or slits 13 best shown in Figs. 1 to 3.
  • slits 13 function as self-sealing slits, they are cut through the surface of applicator head 7 so that plane of the alit forms an acute angle with the perpendicular to the tangent of the curved applicator head at each slit. This is best shown in Fig. 3 as the angle ⁇ .
  • Angle ⁇ may vary somewhat depending upon the product viscosity and delivery rate desired. Usually, this will fall in the range of from about 25° to about 70°, the preferred angle being about 45°.
  • slits 13 can be cut through applicator head 7 in accordance with this invention. Usually, however, these will be two in number which will D e symmetrically disposed near the top of the dome formed oy applicator head 7. In the preferred form of the invention, each slit will be a segment of the same circle which will have a diameter in the range of from about 1/4 inch to about 1 1/2 inches.
  • container portion of the present dispenser takes the form of a squeeze bottle 3.
  • This is necessarily made of flexible material which will usually be a flexible plastic material.
  • a number of materials are known in the prior art which are suitable for this purpose.
  • tne following may D e mentioned: low density polyethylene, linear low density polyethylene.
  • FIG. 4 Anotner modification of this invention is illustrated in Figs. 4 tnrougn 9.
  • This is a standing dispenser best shown in Fig. 4 in the position in which it will ordinarily be stored before and after use.
  • This comprises a supporting base 12 which takes the form of a dish or bowl into which the applicator 5 will fit.
  • the slits 13 face downwardly and the contents of the container flow downwardly under tne influence of gravity to fill the space immediately behind slits 13.
  • tne dispenser is ready for the next use. It needs only to be picked up and squeezed in the manner described in more detail below. This will cause some of the contents of the container e.g. cream or lotion 12 to be expressed through the slits 13. After the squeezing pressure is released, the cream or lotion 12 expressed as best shown in Fig. 6 is ready to be applied to the armpit of a subject.
  • Tne modification of this invention shown in Figs. 4 through 9 is also provided with an external shielding member 14 which is not readily deformed.
  • This will take the form of an elongated cup having a widened mouth 26 which may be slipped over squeeze bottle 3.
  • shielding memoir 14 will be made of a rigid material such as a rigid plastic e.g. polypropylene or high impact polystyrene.
  • a rigid plastic e.g. polypropylene or high impact polystyrene.
  • the applicator head takes the form of a threaded applicator head 15 preferably moldea as a single piece.
  • Applicator head 15 is likewise provided with a domed shape having the same characteristics as applicator nead 7 described in the modification of this invention shown in Figs. 1 through 3.
  • an annular skirt 17 is provided which is integral with applicator head 15 and depends from the underside thereof.
  • Threads 19 are molded on tne internal surface of annular skirt 17 and are best shown in the detail drawing Fig. 9. Threads 19 are designed to mate with the threads 20 on the external surface of a squeeze bottle 3 whereby the threaded applicator 15 may be secured to squeeze bottle 3 containing the product to be dispensed.
  • Threaded applicator 15 is constructed with an overhang portion 21 that extends radially from the outside wall of annular skirt 17. This forms an annular space 23 which surrounds skirt 17 having a roof 25 and a side wall 17. Side wall 27 is provided with a bead 29 which is designed to engage a corresponding Dead on the neck of shielding member 14 when the applicator 15 is screwed onto squeeze bottle 3.
  • Threads 24 are also provided on the outer surface of widened mouth 26 of shielding member 14. This is best seen in Fig. 7. Threads 24 mate with corresponding threads (not shown) in supporting base 12. By means of these mating threads, the total dispenser unit may be screwed into base 12 and the standing unit shown in Fig. 4 is obtained.
  • auxiliary venting means 4j is provided in squeeze bottle 3. In the modification illustrated, this vent is disposed in the roof 44 of squeeze bottle 3. Vent 43 is cut tnrough the floor of a small concavity 45 that is formed in roof 44.
  • Vent 43 takes the form of an upper V-shaped trough 45 and a lower slit 47.
  • the vacuum created therein causes air to rush into V-shaped trough 46 and open slit 47.
  • slit 47 closes sealing off the contents of squeeze bottle 3 from the atmosphere.
