Claims;

This invention relates to an improved con, v

tainer closure and is more specifically concerned,

with such means operable by a single simplemoveno externally visible parts ment and having when the container is closed.

While innumerable means have from time to time been provided for holding containers in a closed condition, relatively few of them are ef' fective and also entirely concealed from external view when the box is closed. Nevertheless, in

providing an attractive container fora high grade product, such as a container made from highly polished mahogany, tainer not be disfigured when'it is inclosed posi' tion by externally visible hinges, plates, latches or other conventional closure means.

It is further desirable in providing such a ci o? releasable by a simple manual movement so that the container: may be opened sure that it be or closed with a minimum of effort. However;

this ease of operation should not be accomplished.

by the sacrifice of firm holding when the container is in a closed condition. I Y Further, where the container is used in the distribution of a high grade article of commerce,

such as a finely made shaving razor,'so that it will be manipulated with considerable frequency over a long period of time, it ise'specially desirable that the closure mechanism parts and a maximum of sturdiness and duraL bility.

Therefore, the principalobject of this invention i is to provide means for maintaining.acontainerin a closed position without recourse to a latch .or other conventional means-of closure Another object of this invention is to .provide; a means for securing the cover of a container; firmly in place by a rapid single movement in such a manner that the cover will remain in that position without slippage.

- Another object of this invention is to provide means for securin a container and acooperating cover firmly together inclosed relationship Whichf all elements of the closure] means when saidparts are insuchclosedrelation will conceal from view ship.

Anotherobject of this invention isto provide means as aforesaid which willoperate cleanly and firmly and which willhaveahig'h degree of durability and resistance to wear and rough usage.

A further object of closure means as aforesaid'which are of such simple construction that the fabrication thereof can L be efiected rapidly-andinexpensivdy.

it is desirable that the connot only act cleanly and positively but that it have a minimum of moving my invention is to provide Qtherobjects and-purposesof myinvention will be this-type upon inspection of'thefollowing specification' with reference to the accompanyir lg- 5a ldr'awing.

sli ht .c n r in thre ai afielylqn .halrflof th inne section from the open part An arcuate space 9 has been provided at one end of this top section to accommodate the head of a safety razor, for which this particular container is designed. This hollowed section, however, is not an essential part of the invention.

The other section of the box, which may be either section, but which will be called the bottom section for purposes of convenience in naming, likewise has a longitudinal body in, which forms the bottom of'the box, and an upwardly extending end wall ll perpendicular thereto. This section has a. substantially arcuate center portion also terminating at each side in recesses [2 over which flanges l3 and Ba project inwardly as shown in Figure 5. These flanges and recesses are of size and shape to interlock with the'flanges 3 and 3a and their associated recesses when the container is assembled. The flanges are cut out ing backwardly in the direction of compression of the spring I1 either the forward wall of the pin or at least an inner part of the forward wall of opening 16, this difficulty is overcome. With the described means so constructed, the pin in its most forwardly position will readily comalong the center portion of each side, as seen in Figure 6, for purposes to be shown hereinafter.

Along one side of the bottom section there is provided a cylindrical opening l4 extending into the otherwise solid side portion of said bottom l8 at the end thereof. This opening contains a freely moving cylindrical member l5. A rounded peg i6 is immovably attached to the cylinder and projects upwardly through the slot IS in the manner shown in Figure 7. This cylindrical member is normally held in the position shown in Figure 2 by a spring [1, but may be the spring when required by the closing or opening operation. The peg is of size to be received easily by the opening 5 in the top section of the container.

Figures 4 and 5 show the bottom and top sections of the container in longitudinal section in two relative positions with respect to each other during an opening or closing operation. The functioning of this box closure can readily be seen therefrom. With the two sections held in the relative positions shown in'Figure 4, the top section I is moved downwardly until the opening 6 in the top section is entered by the peg l6 of the bottom section. At this point the flanges l3 and 13a in the top section rest upon, or approach close to, bottom section. In order to engage these two sets of opposing flanges, moved longitudinally with respect to the bottom section in a rightward direction as the parts appear in the drawings or backwardly as referred to in the claims. The engaged peg 15 will move the cylindrical member l5 also rightwardly and will cause the spring l'lto compress. As the flanges pass each other and the top and bottom sections are manually urged together they will fall into the positions with respect to each other from which interlocking of their respective flanges and recesses may be effected. When the manual holding is then released from the top section, the spring, acting through the cylindrical member l5 and the peg IE, will force this top section in a closing direction or forwardly as referred to in the claims. Thus the flanges will be carried into engagement the beginning of which is shown in Figure 8 and a closure provided which is simple and effective.

By tapering the inner part of the opening 6 above described there is secured further tightness in the holding function. The need for and purpose of this will be apparent from the following. 7

As will appear from an inspection of Figure 4 the pin It must necessarily be able to enter the the top section is then moved backwardly against the flanges 3 and 3a of the Y mence to enter the opening l6, but as the pin goes in further it will be pushed backwardly sufllciently with respect to the top member in that when it comes forwardly again as the box is closed it will not come quite as far forwardly as the position of the stop. Thus tension of the spring will act constantly to urge the parts together and prevent any looseness. In the particular embodiment disclosed this is secured by slightly tapering the inward portion of said opening. Thus the pin is permitted to enter the opening in one longitudinal position with respect to the top member l shown in Figure 4 but when the pin enters all of the way into said opening it will be forced to move slightly to the right with respect to said body I from the position as shown in said Figure 4. In this way, when the box is fully closed the pin is moved slightly backwardly against the spring 11 and is held slightly away from the forward end of the slot l9 which acts as a stop for the pm. By this means a constant tension by the spring is held onto the box parts when said parts are in a fully closed position urging them firmly together.

An alternative manner of effecting the same end is shown in Figure 9. Here the opening 6a, corresponding to the opening 6 in the other figures, has straight and parallel sides, and the shifting is provided by beveling the forward side of the pin I611, which corresponds to the pin it in the other figures. Other variations, such as merely rounding the top of the pin or slanting only a forward part of the opening, will be evident to those acquainted with articles of this sort.

In order to openthe box, the only movement necessary is again to displace the top of the box rightward with respect to the bottom as the same appear in the drawings sufllciently to disengage the flanges, at which point the top may be completely removed. As the top is removed the peg I6 is released and it, together with the cylindrical member 15, will snap back to its leftward position.

The advantages of this box closure are evident. There are no outside latches or hinges to come loose or to rust, or to disfigure the simplicity of the design of the container; the box may be 'opened and closed with a single rapid movement,
