CLOSURE FOR CONTAINERS.
Application filed April 3, 1923. Serial No. 629,731.
My invention pertains to an improvement in containers or collapsible tubes as employed, for holding powder,paste, and the like. My invention relates particularly to a novel mechanism for closing the mouth of containers of the character in question.
The main object of my invention is to provide a tube closing device of such nature that it may be employed on containers of standard construction from which the cap may be detached without any possibility of losing or misplacing the same. Another object of my invention consists in providing a double sealing arrangement for the mouth of the container.
Heretofore, in the construction of containers for powders, pastes, and the like, it has been customary to employ an ordinary screw cap member having an eye memberv soldered thereto by means of which the cap is connected to the container by a chain or other flexible connection. Also, it has been customary to employ a non-detachable cap which must be turned so as to cause an opening in the cap to register with an ofi-center opening in the top of the container. -The objection to the first mentioned type of closing device is that the flexible connection always becomes twisted and kinked and sometimes becomes broken by reason of the fact that it must be twisted each time the cap is removed from the container. Furthermore, an ordinary screw cap frequently does not provide an air-tight seal for the container. A closing device of the character employing the tube with registering openings has the objection that it'is never air-tight, and that very frequently it is accidentally left open.
By myinvention I have, eliminated the objections of the aforementioned structures by providing a cap which provides a double sealing arrangement for the container, and, at the same time, is fastened to the container in such manner that the flexible connectingmember cannot become twisted or kinked.
For a better understanding of my invention, reference may be had to the accompanying drawing of which:
Fig. 1 is a side elevational view of a col lapsible paste tube provided with a cap constructed in accordance with my invention; and
Fig. 2 is a cross-sectional view taken di rectly through the middle of the structure illustrated in Fig. 1.
In the drawings I show a collapsible tube having a main body portion 3 and a constricted neck portion 4, having a centrally disposed opening 5 therethrough, and provided with threads on the outer surface thereof. The upper portion of the opening .5 is of hemispherical contour, as indicated at 6, to form a valve seat.
A cap member 7 is provided with an in ternally threaded lip member 8 that is adapted to be placed in threaded engagement with the neck portion 4 of the tube 3. Mounted within the'capmember 4 is a hemispherical valve member 9 havino' a pin 10 projecting from the central portion of the flat side thereof. The pin 10 projects through a centrally disposed opening 11 in the top of the cap member 7. A washer member 12, composed of a compressible material, such, for example, as cork, is dis osed between the hemispherical valve mem er 9 and the inner surface of the top of the cap 7 in such manner as to surround the pin 1.0. The opening ll is of such dimensions, with respect to the pm 10, as to permit free rotative movement of the valve member 9 andthe pin 10 with respect to the cap member 7.
The cap member 7 is attached to the container 3 by means of a chain, or other flexible connection 13, which is attached at one end to the pin 10 in the cap member 7, and is attached at the'other end to an eye-member 14, which is rigidly attached to thetop of the container 3.
From the foregoing description, it will be apparent that when the cap is first applied to the top of the neck portion 4 the valve member 9 will rest upon'the valve seat 6 without movement with respect thereto. As the cap is gradually screwed into place, pressure is exerted upon the top of the valve member 9 through the washer 12, thus causing the member 9 to move into a sealing engagement with the hemispherical valve seat. 6. Also the washer member 12, being compressed by the tightening of the cap '7, fornm a sealing engagement around the opening 11. Furthermore, the pressure of the washer member 12 against the top of the cap member 7 will cause the top surface of the threads on the cap member 7 to very closely engage the bottom surface of the threads on the neck portion 4, thus again sealing the container.
It will, therefore, be apparent that for any air to enter the tube 3 it must first pass through either the tightly wedged threaded connection between the cap and the neck portion 4, or it must pass through the opening 11 and between the compressed washer 12 and the top of the top member 7, or between the washer 12 and the top of the valve member 9. In any event, it must also pass through a second sealing arrangement in order to enter the tube, that is, between the invention 1 have provided a. container sealing device in which a. double seal is made to prevent the admission of air to the container, and in which twisting or kinking of the flexible connection between the cap and i the container is absolutely eliminated.
While I have shown but one form of my invention and have described in detail but a single application thereof, it will be apparent to those skilled in the art that it is not so limited, but that various minor modifications and changes may be made therein without departing from the spirit of my invention, or from the scope of the appended claims.
What I claim is 1." The combination with a container comprising a collapsible body portion and a rigid neck port-ion formed with an aperture and a valve seat, of a cap for the container adapted to be detachably secured to the neck, a closure valve for the aperture in the neck disposed between the cap and the seat, and a connection extending from the-valve through an aperture in the cap and attached to the outside of the container adapted to secure the cap and the valve against loss from the container and to. permit of free rotational movement. between the valve and the cap.
2. A container provided with. a neck portion having an opening therein, a cap member adapted to fit over said neckportion, and a valve member rotatively mounted within said capand adapted toclose said opening and provided with a portion extending through the top of said cap and retaining means secured to said portion and to said container.
3. A container provided with a neck portion having an opening therein, a cap member adapted to fit over said neck portion, a valve member rotatively mounted within saidcap and adapted to close said opening and provided with a portion extending opening therein, a valve seat formed on the neck portion adjacent the opening, a cap member adapted to fit over said neck portion, a metallic valve member rotatably mounted within said cap adapted to engage the valve seat to close said opening and provided with a portion extending through the top of said cap, and a compressible annular member disposed between said cap and said valve member and around the extended portion of said valve men'iber.
5. A flexible metallic container provided with a rigid metallic neck portion having an opening therein provided with a valve seat, a cap member adapted to fit over said neck portion in threaded engagement therewith, a metallic valve member disposed within said cap member and adapted to engage said valve seat, and compressible means disposed in said cap memberintermediate said valve member and the top of said cap member.
6. A container provided with a neck portion having an opening therein a cap member adapted 'to fit over said neck portion, a valve member rotatively mounted within said cap and adaptedtoclose said opening and provided with a portion extending through the top of said cap, and means for effecting a sealing engagement between said valve member and said cap.
7. The combination with a container comprising a collapsible body portion and a rigid neck portion formed with an aperture and a valve seat, of acap for the container adapted to be detachably secured to the neck, a closure valve for the aperture in theneck disposed between the cap and seat, and flexible means connecting the cap and "valve to the outside of the container.
8. The combination with a container comprising a collapsible body portion and a rigid neck portion formed with an aperture and a valve seat, of a cap for the container adapted to be dctachably secured to the neck,
a closure valve for the aperture in the neck disposed between the cap and the seat, and a connection extending from the valve through the cap to the outside of the container adapt- -ed to secure the cap and-the valve against loss from the container and to permit of free rotational movement between the valve and the cap.
In wltness whereof, I have hereuntoslgned my name.
