Description:

My invention relates to a non-spillable cup, and has for an object to provide a cup that will hold liquid and has the dual advantage of being capable of being drunk from and yet will minimize spilling if tipped over on its side.

Another object of the invention is to provide a cup with a cover that will prevent spilling when the cup is upright, and at the same time the cup can be drunk from without removing the cover.

Further objects are to provide a cup of the character mentioned whose cover can be easily removed for filling the cup and which cover can be moved to an entirely closed position that will prevent all liquid from spilling from the cup, irrespective of the position of the cup.

Still other objects of my invention are to provide cuch a cup that is economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description.

However, the drawings merely show and the following description merely describes one embodiment of the present invention, which is given by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Fig. 1 is a top, plan view of a cup embodying the foregoing objects.

Fig. 2 is a view similar to Fig. 1, but showing the cover in a different adjusted position.

Fig. 3 is a transverse section, taken on the line 3-3 of Fig. 1.

Fig. 4 is a vertical section, taken on the line 4-4 of Fig. 1, and partly in elevation.

Referring more in detail to the drawings, the reference number 5 generally indicates the body of my present cup. The cover is generally indicated by the numeral 6. The inner face of the body 5 has a shoulder 7 upon which the cover 6 rests when in place.

To permit liquid in the bottom compartment 8 of the cup to flow past the cover, I provide a recess 9 that extends down below the shoulder 7, as best shown in Fig. 4. The cover 6 has a slotted opening 10 at the bend between the floor 12 and normally upright wall 13 of the cover.

When the cover 6 is turned for the opening 10 to register with the recess 9, liquid in the compartment 8 may flow around the edge of the floor 12 and outside of the floor 12 of the cover, whence it can be drunk. When the cover 6 is turned so that the opening 10 is out of register with the recess 9, then liquid in the bottom compartment 8 cannot flow therefrom.

To aid in such flow, an air vent 14 is arranged in the cover diametrically opposite the slotted opening 10, in the bend between the floor 12 and the normally upright wall 13. A small recess 15 is arranged in the inner face of the body 5 of the cup, through and below the shoulder 7, diametrically opposite the recess 9. Thus, when the slotted opening 10 is in register with the recess 9, the air vent 14 is in register with the recess 15; and when the slotted opening 10 is out of register with the recess 9, the vent 14 is out of register with the recess 15.

The floor 12 of the cover 6 is preferably pitched to slope downward toward the slotted opening 10, as indicated by the shade lines on the bottom . 12 in Figs. 1 and 2.

A locking means may be employed for my present cup, if desired. A satisfactory form is shown in the drawings, to wit, bayonet grooves at opposite sides of the inner face of the cup, above the shoulder 7. Each bayonet groove comprises a vertical groove section 16 and a horizontal groove section 17. Lugs 18 on opposite sides of the outer circumference of the cover 6 Sengage in the bayonet grooves. That is to say, in order to lock the cover 6 in the body 5, the cover is inserted in the body with the lugs sliding downwardly in the vertical groove sections 16.

Then the cover is turned, thus causing the lugs to travel in the horizontal groove sections 17, thereby locking the cover in position. To remove the cover, this operation is, of course, reversed.

Notches 19 and 20 are made in the lips 21 and 22 of the cover and body, respectively. When Sthe notches are in vertical alinement, the lugs 418 are alined with the vertical groove sections 16, so that the cover is in an unlocked condition and may be lifted off. It is to be understood that my present cup may be used with or without said locking lugs and bayonet grooves. Due to the relatively close fit between the cover and the body, there is friction, and even without the aforedescribed locking means, when the cover is turned so that the openings 10 and 14 are out of register with the recesses 9 and 15, a partial vacuum is created in the compartment 8, which tends to hold the cover in place on the cup.

The shoulder 7 is not only a support for the cover, but increases the vacuum caused by partial withdrawal of the cover 6, since the shoulder provides an additional impediment to air entering the chamber I around the cover. This shoulder 7, therefore, increases resistance to removal of the cover 6.

My present cup has many uses, including use on shipboard, since it will prevent liquid in the cup from slopping out, even when the vessel is rolling considerably, and it is very useful as a baby cup to minimize spilling when the cup is upset, and many other uses.

In such uses, it is believed clear that a person drinks from the cup with the cover in place, as shown in Figs. 1 and 4. With the air vent 14 registering with the recess 15 and the slotted opening 10 registering with the recess 9, liquid 1 will flow through the recess 9 and opening 10 when the cup is tipped at one side, as indicated by the arrow A in Fig. 4. The person then drinks the liquid that has escaped through the opening 10. To close the cup, the cover 6 Is turned, which S moves the openings 10 and 14 out of register with their respective recesses 9 and 16.

If the locking lugs 18 and bayonet grooves are used, the cover 6 may be lifted out of the body 6 when the lugs 18 are in register with the vertical 2 groove 16 (indicated by the fact that the notches 19 and 20 are in alinement). To lock the cover in place, the lugs 18 are moved downward in the vertical grooves 16 and as the cover is turned, after the lugs reach the bottoms of the vertical 3 grooves, the covers are locked in position.

In the hereunto appended claims, the word "cup" is to be taken to mean a class of containers that comprises both cups and mugs.

While I have illustrated and described what I 3 now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of 4* construction illustrated and described, but desire to avail myself of all modifications that may fall within the scope of the appended claims.
