Application filed December 15, 1919.
T0 aZZ whom it may concern.-
Be it known that I, PATRICK H. QUINN, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Containers, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to containers and particularly to containers for use in bottling and preserving.
The great disadvantage of the old method of preserving is that in order to protect the food, it is necessary to deposit wax material such as paraffin on the surface of the food to exclude air and prevent spoiling. The wax material has to be applied over the entire surface of the food so that a considerable quantity is necessary, thereby increasing the cost of preserving. I
It is therefore the object of this invention to provide a container that can .be hermetically sealed without depositing wax material on the surface of the food.
Another object is to provide a container of this character having a shoulder formed inwardly of its neck closely adjacent the mouth thereof for supporting a stopper in such a manner that the entire upper surface of the stopper and a portion of its'edge projects above the edge of the mouth.
Another object is to provide a container of this character having a shoulder inwardly of its neck the inner marginal edges of the shoulder projecting above the upper portion of the shoulder to provide a stopper penetrating jaw.
A still further object is to provide a con tainer of this character having a screw thread cap attached to compress the stopper over the penetrating jaw.
With these and other objects in view the invention consists in the improved construction to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings in which -Figure 1 is a vertical elevation and sectional view showing the stopper in engage ment with the jaw and shoulder.
Fig. 2 is a sectional view of the neck of the container.
The invention consists of a container 5 which may be produced in the form of a bottle, jar, or like conventional containers used in preserving and bottling. In the Specification of Letters Patent. Patented Aug, 31, 1920 Serial No. 345,112.
drawings I have illustrated a bottle but it is obvious that the invention may be incorporated in any form of container and I therefore do not wish to limit myself to the particular design illustrated.
The exterior portion of the neck adjacent the mouth, is provided with threads 6 and shoulder. This recess causes the inner marginal edge 12 of the shoulder to project upwardly toward the mouth to provide a stopper penetrating jaw 13. The side 14: of the jaw is disposed parallel to the inner surface of the neck while the side 15 inclines from the bottom of the recess toward the side 14:.
A stopper 16 formed of any desired material, preferably cardboard is provided for closing the mouth of the container, and as the depth of the reduced inner marginal edge is slight, the lower half 17 of the stopper is concealed within the neck and supported by the shoulder while the upper half 18 projects above the edge 9 of the neck. An internally screw threaded cap 19 is provided for engagement with the exterior portion of the neck over the mouth and stopper 16.
In use, after the food or substance has been deposited in the container the cap 16 is dipped in melted paraflin and applied to the shoulder 10 while hot. The cap 19 is then screwed on the neck and in view of the upwardly projecting portion 18 of the stopper, the cap will force the stopper into firm engagement with the shoulder 10 so as to cause the jaw 13 to slightly penetrate the lower surface of the cap 16. At the same time the pressure from the cap 19 will cause the lower marginal edges of the stopper to enter the concave groove 11, thereby hermetically sealing the container without depositing paraffin on the surface of its contents.
From the foregoing it will be readily seen that this invention provides a small and inexpensive method of hermetically sealing bottles, jars and like containers, the cap 19 not only causes the jaw 13 to penetrate the stopper 16,.but prevents the paraffin from being cracked by contact with an object so that the seal remains perfect indefinitely. In addition to this after the container has been opened to remove the substance the stopper 16 and cap 19 still provide an airtight closure for the bottle to protect the substance therein.
What is claimed is l. A container of the class described comprising a body including an exteriorly threaded neck, a shoulder formed inwardly of the neck closely adjacent the mouth, a stopper penetrating jaw projecting from the inner marginal edge of the shoulder toward the mouth in substantially parallel re-' lation to the inner wall of the mouth, said jaw cooperating with the inner wall of the mouth to form an endless groove, a paraffin coated stopper having a portion of its lower surface engaged with the jaw, a cap adapt ed to engage the neckover the mouth and paraflin coated stopper, said cap compressing the stopper inwardly of the mouth, whereby the same is penetrated by the stopper penetrating jaw, the marginal edge of the stopper being forced inwardly of the neck into the groove. v
2. A container of the class described comprising a body including a neck, the inner marginal edge of the mouth of the neck being reduced to provide a shoulder, said shoulder being parallel to the mouth of the container, a stopper penetrating jaw proj ecting from the inner marginal edge of the shoulder toward the mouth, saidjaw being disposed flush with the inner surface of the neck and in spaced relation to the inner wall of the reduced portion of the mouth, a stopper having a portion of its lower surface engaged with the jaw, and means engaged with the neck of the container and the stopper to cause penetration of the lower surface of the stopper by said jaw, the marginal edge and periphery of the stopper being forced into engagement with the shoulder between the wall of the reduced portion of the mouth and the jaw.
In testimony whereof I hereunto aflix my signature.
