Description

Jan. 20, 1959 H. D. FORSYTH PACKAGE Filed April 11, 1957 IZ v ATTORNEYS:
United States Patent O PACKAGE This invention relates to packages for medicinal products to be used within a body cavityand, therefore, requiring the use of an elongated nozzle, or tip, and particularly to packages adapted for enema use.
Medicinal preparations packaged in single use, or dose, quantities have come into widespread use. Where the preparation is to be used in a body cavity, it is customary to package it in a bottle or squeeze type tube and use a conventional screw cap for sealing. Packed with the bottle will be an applicator tip and a small quantity of lubricant for the tip. This requires the packaging of several items for shipment, and excessive handling of the several parts when contents of the package are to be used.
Thev principal object of the presentv invention is to pro-V vide a medicinal package for body cavity use wherein the package is designed for shipment with the .applicator nozzle, or tip, in place, protected by an outer cover or sheath.
Another object is to provide a package of this kind having a valve within the applicator tip for controlling the ilow of material from the package, and a primary closure seal made with the tip itself.
A further object is the provision of such a package having the lubricant upon the applicator when the package is purchased making it unnecessary to handle the tip at any time.
Other objects of the invention will become apparent from the following description of one practical embodiment thereof when takenin conjunction with the drawings which accompany, and form part of, this specication.
In the drawings:
Figure l is a side elevation of an enema package embodying the principles of the present invention;
Figure 2 is a top plan view of the package;
Figure 3 is a vertical section through the applicator tip with its seal and the upper part of the bottle, shown on an enlarged scale and taken on the line 3-3 of Figure l; and,
Figure 4 is a horizontal section through the applicator tip and its sealing sheath, taken on the line 4-4 of Figure 3.
In general, the invention consists in a container having an elongated applicator tip on it, with lubricant on the tip and a sheath sealing off the tip and protecting the lubricated portion of the applicator.
Referring to the drawings in detail, the container' is snown as a thin-walled, polyethylene bottle l, which is flexible and can be compressed to expel the contents. The neel; of the bottle is threaded, as at 2, to receive an applicator tip 3. The tip has an enlarged base, or cap, end d which is internally threaded, as at 5', to screw upon the neck of the bottle l. The tip is hollow and tapers outwardly to a crowned end 6, which is apertured centrally at 7 on the central axis of the tubular tip to permit exit of the contents of the bottle. The tip is wardly.
ICC
also of polyethylene, somewhat stiier than the bottle walls, yet having some exibility.
The base 4 of the applicator is Arecessed as at 8 to receive a exible disk valve 9. The valve seats in the recess and upon the end of the bottle neck, and is clamped between the applicator and bottle neck when the applicator is in place. Valve disk 9 has a diametrical slit 10 which extends across the disk, but stops short of the edge on either side. This slit divides the central portion of the disk into two opposed lips which may flex outwardly under the force of the contents in the bottle when the bottle is compressed and permit the contents to ow out into the applicator and through the aperture 7. The disk is formed of rubber or other suitable ilexible and resilient material which will spring back to its original plane after being ilexed and be self-closing. The disk valve also serves to prevent leakage of the contents of the package after the primary seal is broken and the bottle is inverted for use. It also prevents sucking back of the liquid from the body cavity after the deflated bottle is released.
`Vhen the applicator is in place, it will be coated near the tip with a suitable lubricant, such as petroleum jelly, and a sealing sheath 11 slipped over the end. In actual practice, a small amount of the lubricant will be placed in the sheath and when the sheath is put in place the lubricant will coat the end and adjacent portions of the tip. The sheath will also be of polyethylene, or similar material, and have approximately the same degree of stiffness as the applicator. The sheathwill be of similar shape to the projecting end of the applicator and of slightly larger diameter, so that when it slips over the applicator tip there will be a smaller annular chamber 12 formed between the tip and the sheath in which the lubricant on the tip will be housed. The lower end of the sheath is provided with a relatively stiff annular ange 13 which serves to rigidity the open end of the sheath. The sheath is 1of such length that when it ispressed down tightly over the applicator its lower inner edge 14 will contact the tip in the area where it swells outwardly to merge into the base 4 and will form a tight seal around the tip, preventing the escape of the lubricant and keeping air from reaching the lubricant chamber and drying out the lubricant. Thus, the sheath forms with the applicator tip a chamber for the lubricant and seals that chamber from atmosphere.
The upper end yof the sheath l1 is crowned at 15 similarly to the crown on the applicator tip. Extending inwardly of the sheath in an axial direction and on the central axis of the sheath is a sealing stud 16. The stud has a conical leading end 17 and converges from the maximum diameter of the conical leading portion upwardly to its juncture with the inner surface of the sheath crown. The upwardly converging portion 18 provides a stopper to seal the aperture 7 in the applicator tip. When the sheath is slipped over the applicator it will slide freely until it is almost seated. The conical end of the sealing stud will lit into the aperture 7 and expand the aperture slightly as it passes through. At about the time that the base of the cone .7 passes through the opening, the lower edge 14 of the sheath will corne in contact with the surface of the applicator. Further downward movement will tend to compress the applicator slightly and the resiliency of the material will tend to move the sheath out- However, the base of the cone has at this time passed completely through the opening and the upwardly tapering portion 18 will be in the aperture. This tendency of the applicator to move the sheath upwardly will hold the sealing stud in tight sealing contact with the When the sheath is in place it will hold When it is desired to use the contents of the package the sheath can be gripped at the annular flange 13 and pressed outwardly. This will cause the base of the cone of the sealing stud t0 snap through the aperture 7 freeing the sheath for removal from the applicator.V The lubricant which has been in the chamber 12 will bey in good condition, forming a coating over the surface -of the applicator near the top and the package will be ready for use. Pressure on the sides of the bottle will force the liquid through the valve 9 and out through the aperture 7 in the applicator.
The device is adapted to have but a single use and is therefore disposable. Use of a plastic such as polyethylene gives the parts of the package the flexibility which they need and, at the same time, permits very cheap manufacture of the package. It will be readily apparent that the package will be much simpler to use with the applicator and lubricant in place when purchased. The sheath will form a complete seal against leakage of the contents of the bottle and will also protect the lubricant and prevent contact of the applicator with foreign objects prior to the time it is to be used. The new structure will simplify packaging, and materially reduce handling costs.
While in the above one practical embodiment of the invention has been disclosed, it will be understood that the details of structure described and shown are merely by way of illustration and the invention may take other forms within the scope of the appended claims.
