5 Claims. (Cl. 12s-260) This invention relates to dispensing devices, and more particularly to that type of dispensing devices wherein the material tobe dispensed is extruded as required from the container.
The objects of the invention are to obtain an improved dispensing device of the character indicated in which the material may be extruded without shortening or squeezing the container;
vto provide such a device capable of being inserted into a cavity of the human body and the material extruded at the inner end of the container; ,to enable the device to be promptly used without difficulty of preparation; to avoid the necessity oi' removing a cork or stopper; to provide a complete device capable of reuse with new containers; to secure simplicity of construction and operation; and to obtain other advantages and results as may bebrought out in the following description.
Referring to the accompanying drawing, in which like numerals of reference indicate similar parts throughout the several views;
Figure 1 is a side elevation of a dispensing device in accordance with our invention, showing the same ready to operate to extrude the material;
Figure 2 is a plan or end view of the device;
Figure 3 is a longitudinal sectional view, as upon line 3 3 of Fig. 1, but with the material partly extruded;
Figure 4 is a similar longitudinal sectional view of the container alone before the material is extruded;
Figure 5 is an elevation of a modiiled construction, and
Figure 6 is a longitudinal sectional view thereof on line 6 6.
In the specific embodiment of the invention illustrated in said drawing, the reference numeral I0 indicates the container for material II. The container is preferably of an elongated tubular construction with one end closed until used and the other end open except for an applied closure such as the cork I2 shown in Figures 1 to 4 or the plunger head shown in Figures 5 and 6. In the construction of Figures 1 to 4, this open end of the container is shown as screwthreaded, the screw-threads I3 being shown as pressed or moulded as part of the container. The cork I2 is applied to the container so as to be positioned .substantially below the screw threads so as to leave a neck portion of the container which is not filled or otherwise obstructed.
kAs a feature ofthe present invention, we provide a container which, while initially closed at one end as received by the consumer, yet it may be punctured or otherwise opened thereat. In the drawing, is illustrated a hole Il at the tip end of the container, which hole, in Figures 1 and 4 is closed by an applied closure I5 such as paraiiin. However, it is to be understood that by use of puncturable material, such as a thin cellulose material, a preformed hole is not required, but may be formed by puncturing when the device is to be used.
In order to extrude the material within the container through the hole or puncture, we pref-- erably provide means for forcing cork I2 `longitudinally of the container.y Carrying out this feature, we have illustrated a cap I6 hollowed out and threaded to be applied upon the threaded end of the container. 'I'hrough this cap is slidably carried a plunger stern II having a plungerhead at its inner end adapted to retract into the hollowed-out part ofthe cap'.4v The cap may accordingly be applied without disturbing the cork, and then by pushing inwardly upon the stem the cork will be slid, without any tilting, as far as desired. Preferably the container is of the right size so that its contents will comprise a single dose or application, and therefore the cork will be pressed to the punctured end of the container to extrude vall of the material at one time under these circumstances.
The outer end of the stem Il may convenently be provided with an enlargement forming a flnger piece or button I8. By shaping the exterior of the cap circumferentially concave, the same may beheld between two ngers of one hand and the plunger pressed in with the thumb of the same hand. After the material has been extruded, the instrument, including the container, is withdrawn from the body, the container removed'and thrown away, and the cap, with its plunger, applied to a new container ready for use again.
In order to make it convenient to puncture the hole I4, we have shown the outer face of the Abutton I8 recessed, as at I8, with a size and shape may be of such nature so as to be forced out by I6 internal pressure created when pushing the plunger against the material.
In the construction of Figures and 6, a unitary device including the plunger is shown, it being anticipated that the whole device will be discarded after use. The body portion of the device preferably provides an elongated container 2| the outer end of which provides a reduced neck 22 which expands thereabove into a cap portion 23, shown as hollow and large enough to receive the users finger. A plunger 24 is provided with a plunger-head 25 within the container, initially near the neck thereof, and with a stem 26 extending through said neck into the expanded portion oi the device. A nger-piece or button 21 is provided on the outer end of the stem enabling the plunger to be conveniently pushed inwardly. The end of the expanded portion containing the plunger is preferably diagonally open so as to more readily accommodate the users finger when pressing the plunger its full length.
The end of the container opposite from the neck is puncturable to permit extrusion of the material Il within the container. Preferably the body portion is of inexpensive sheet material such as paper or. cellulose material, in which event it is convenient to draw the end of the container together after the material has been intro-4 duced, and sealing by twisting the material thereat, by parafiining the same if desired, and by divers other means.
Obviously other detail changes and modifications may be made in the construction and use of our improved dispensing device-without departing from the spirit or scope of the present invention, and we do not wish to be understood as limiting ourselves to the precise details shown or described except as set forth in the following claims when construed in the light of the prior art.-
Having thus described the invention, We claim:-
1. A dispensing device comprising an elongated container having one end thereof open and the other end closed, said closed end being constructed so as to rupture for discharging the contents, said open end having a cork within the same spaced inwardly from the open end for preventing withdrawal of the cork and discharge of the contents from the open end, and said container providing means between the cork and open end for retaining the cork spaced inwardly within the container.
same spaced inwardly from the open end for preventing withdrawal of the cork and discharge of the contents from the open end, said container having its wall next the open end spirally impressed with a screw thread thereby providing means between the cork and open end for retaining the cork spaced inwardly within the container.
3. A dispensing device comprising an elongated container having one end thereof open and the other end closed, said closed end being constructed so as to rupture for discharging the contents, said open end having a cork within the same spaced inwardly from the open end for preventing withdrawal of the cork and discharge of the contents from the open end, said container having its wall next the open end spirally impressed with a screw thread thereby providing means between the cork and open end for retaining the cork spaced inwardly within the container, and means for pushing the cork longitudinally inward of the container, said means comprising a cap threaded on to the exterior of said spirally threaded portion of the container and a plunger slidable in said cap and having a plunger head of less diameter than the cork and insertable through the impressed screw threads of the container.
4. A dispensing device comprising in combination with a container having one end screwthreaded and receiving a cork inset from said end, the opposite end of the container adapted to be opened in use, a cap adapted to be applied to said screw-threads, and a plunger passing through said cap and having an inner end adapted to engage and push the cork toward the opened end of the container.
5. In combination, an elongated capsule-like container for substantially complete and unprotected insertion in a body orifice, one end of said container being closed and the other end open, said closed end being constructed so as to rupture for discharging the contents in said body orifice, said open end having a cork for retaining the contents and also having means for mounting the container by its said open end for maintaining the container unenclosed for substantially its entire length when mounted, and means applicable to the said mounting means for supporting the said container in use, this last said supporting means providing operative mechanism for impelling the cork and contents longitudinally of the container toward the closed end for impelling the contents through the rupture thereof.
