9Claims.

the container is to be used to store materials that would be injured by moisture, dust,xvermin, etc.,

or which contain a volatile element that would escape unless the materials were kept in an absolutely tight enclosure. Such a container also. is

desirable for holding materials such, for instance, as tobacco, cigars, and the like, which should be kept in an atmosphere of relatively constant humidity. v

With these considerations in view, it is the a container of the general character indicated which will have an air tight closure that can be moved readily to open the container or to close and seal it again. It is also an object of the invention to devise an article of this general character which can be economically manufactured and which shall be of sturdy and substantial construction.

The nature of the invention will be readily read in connection with the accompanying drawlugs, and the novel features will be particularly pointed out in the appended claims.

Referringnow to the drawings:

Figure 1 is a view partly in front elevation and v partly in vertical cross section, showing a container constructed in accordance with this invention; and

Fig.- 2 is a cross sectional view on the line 2-4, Fig. 1.

The construction shown comprises a sheet metal box, the lower or body portion of which .is designated at 2. The upper part of each wall of this box is folded over, as indicated at 3, to form a horizontal shoulder 4. Below this shoulder the metal is bent toward the wall or side of the box and is soldered thereto at 5.

The cover 5 of the box is of the usual construction except that the central portion of the cover is preferably depressed as indicated at I,

o and this cover is hinged to the rearward side of the box at 8, Fig. 2. When the cover is in its closed position the lower edge of its downwardly turned margin may rest on the external shoulder 4 of the box, and means is provided to draw this cover firmly down on the shoulder. In

chief object of the present invention to devise understood from the following-description when Serial No. 280,950

the construction shown a fastening means of the toggletype has been used for this purpose.

This fastening device comprises a U-shaped metal strap i0 pivoted to the front edge of the cover at II, and also pivotally connected by means of a pin I! to a handle or lever 13 havinga pointor toe It to enter a recess l5 formed in a bracket Ii that is riveted to the front of the box. This device is shown in Fig. 2 holding the cover in its closed position, and it will be seen that when the handle it is swung toward the left it will pivot on the point l4, thus causing the pin I! to swing upwardly and thereby release the cover. A swinging movement of the handle in the opposite direction operates through these parts to exert a powerful closing movement on the cover. No novelty, however, is claimed in this particular fastening means and it may be replaced by any other suitable fastening device.

It will be observed that the cover 6 does not close the top of the box tightly, and for the purpose of performing this function a closure plate or inner cover 18, preferably made of resilient material such as sheet steel or brass, is secured to the central depressed portion I of the cover 6 by means of bolts 19-19. When the cover is closed. the margin of this plate I overlies the edge 3 of the open top of the container and this marginal part is preferably grooved to receive a gasket 2. made of rubber, cork, or any other suitable material. This gasket preferably is cemented in the groove in the margin of the plate I. The heads of the bolts l9-|9 are soldered to the plate II or tight joints are formed between these bolts and the plate in some other suitable manner.

It will now be evident that when the cover 6 is swung down' into its closed position, the gasket 2. will engage the edge 3 at the top of the container or box 2 just before the cover reaches its lowermost or completely closed position. The elasticity of the plate l8 and the cover 6 will resist yieldingly the continuation of the closing movement of the cover, and as this movement is completed the marginal portion of the closure plate It will be sprung upwardly, as shown in the drawings, thus causing the plate to press the gasket 10 firmly against the upper edge 3 of the container and thereby make an air tight. joint at this edge. material, both the resiliency of this part and also that of the plate 18 will be utilized in pressing the gasket 20 firmly against the edge 3.

It will be seen'that the depression of the cen- If the cover 6 is made of resilient tral portion l of the cover provides ample space for the yielding movement of the plate It and the depth of this depression or oflset may be made such that it will be impossible to spring the plate l8 far enough to permanently distort it. One ,or more shims 2| may be placed between the plate i8 and the depressed portion 1 of the cover to increase the range of movement of the marginal portion of the closure plate it desired. It will also be observed that the rearward edge of the opening in the top of the box is set inwardly by reason of the ofl'set 22, Fig. 2, and that, due to this construction and the position of the hinge 8 relatively to the adjacent part of the edge 3,the gasket 20 will come into .contact substantially simultaneously with all parts of the edge 3 so that an approximately uniform flexure of the entire margin of the plate is produced.

It is to be noted that the outer cover 6 has a down-turned flange somewhat larger than the.

- the cover or cap 6 is readily moved up and down for opening and closing the container. 015 furtherimportance is the fact that the inner cover I8 is formed from an imperforate fiat sheet of resilient metal and comprises a flexible disk-like member with its gasket means 20 carried therewith, and the downwardly directed flange of the outer cover 5 embraces and protects this inner cover sealing member [8, 20. The central portion of the inner cover It is held to the outside cover a 6 which leaves the peripheral portion 01 said inner cover l8 and its gasket'lll tree to exert a resilient pressure for evenly-seating the gasket upon and all the way around the container opening 3, thereby providing a sealed fit over said opening. p

n The opening at the top of the container 2, as defined by the fold or edge 3, forms an uppermost single rim against which the gasket 20 engages by reason 01' the peripheral or marginal pressure of the resilient inner cover I! made of sheet steel or brass. Note also the importance of a suflicient-marginal or peripheral distance or annular area to impart resiliency at said marginal portion of theinner cover it where the latter evenly engages and seals against the opening 2. Furthermore, the gasket 20 is carried with and forms a unitary part of the cover structure so as to raise and lower therewith. Another feature of this container-cover resides in the smooth outer surface of the cover 5 which is more'or less flat and forms a plain surface free of projections. .And the down-turned marginal flange of the outer cap 6 forms a drain which prevents moisture or drops of water from getting up into the gasket 20 and. the inner resilient cover l8 which backs the gasket. Also the outer cap 6 is solid or closed, and hence it is moisture proof from the top.

This invention thus provides a closure construction for containers and enclosures which is of very simple form, is economical to manufac- The invention considered in its broader aspects may be embodied in many forms, each having its own advantages. For instance, the closure may be substantially rigid and be yieldingly held in its closed position, the resiliency of the cover being depended upon for this action, or, the closure itself may be resilient and the cover or other supporting means case will necessarily be controlled as to some particulars by the nature of the container on which the closure is used.
