Aug. 18, 1936. c. E. MISFELDT CONTAIN-ER Filed June 10, 1935 INVENTOR ATTORNEY MM W v I Patented Aug. 18, 1936 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to containers especially adapted for substances which when contacted by air deteriorate or become gaseous and the present invention has for its primary object the provision of a practical and efficient means for dispensing the contents in desired amounts with minimum exposure of the contents to the air.
With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a vertical sectional view illustrating a container constructed in accordance with my invention.
Figure 2 is a top plan view illustrating the same.
Figure 3 is a sectional view taken on the line 33 of Figure 1.
Figure 4 is a fragmentary sectional view showing a discharge tube for the container.
Figure 5 is a similar view showing a slight modification of my invention.
Referring in detail to the drawing, the numeral I indicates a container which may be of any desired shape and for the sake of convenience has been illustrated as being cylindrical in form closed by a cover 2, the latter having threaded connection with the container and if desired, a suitable gasket may be provided between the cover and the container. Formed in the container I and extending from the bottom thereof to the open end is a discharge tube 3 having communication with the interior of the container at the bottom of said container, as shown at 4. The cover is cutaway to expose the upper end of the tube, as shown in Figure 1, and said tube at its upper end is internally screw threaded to receive a threaded plug or stopper 5 to normally close the tube to the atmosphere. The upper end of the tube is cutaway or flared to form a pouring lip 6, it being 45 noted that the screw threads of the tube extend below the lip so that when the plug 5 is threaded in the tube said tube is completely closed or sealed to the atmosphere.
A feed stem 1 is journaled to the cover and extends downwardly in the container and has one end arranged exteriorly of the cap 2 and equipped 5 with a finger piece 8. Threaded to the feed stem is a piston or plunger 9 having wiping contact with the walls of the cylinder and is cutaway to receive the tube which prevents the piston or plunger fro-m rotating with the feed stem but 10 which will permit said piston or plunger to slide in the container by the rotation of the feed stem.
The container and other parts of this invention may be constructed from any material suitable for the purpose and the contents of the con- 15 tainer is arranged between the bottom of said container and. the piston and after the removal of the plug 5 the contents may be forced from the tube in desired amounts by the rotation of the feed stem with the contents only having mini- 20 mum exposure to the atmosphere.
Instead of employing screw threads in the plug 5 the latter may be unthreaded, as shown in Figure 5, and closed by a removable stopper l0.
Having described the invention, I claim: 25 A container comprising a body closed at one end and open at its opposite end, a cap threaded to the body for closing the open end of the latter, a discharge tube formed integrally with said body and arranged interiorly thereof and extending 30 from the closed end to the open end, said tube being in communication with the interior of the body at the closed end of said body, said cap having a cutaway portion to expose the discharge end of the tube, means for opening and closing 35' the tube, said tube at its discharge end being cutaway to form a pouring lip, a feed stem threaded to the cap and extending into the body, a finger piece secured to the feed stem, a piston threaded to the feed stem and having wiping contact with the walls of the body and cutaway to receive the tube to prevent rotation of the piston with the feed stem and to cause said piston to slide in the body by the rotation of the feed stem to expel the contents of the body through the tube.
