The parts are held together by cooperating means when in closed position, and they have associated therewith closure holding means which are entirely concealed from view wherr'the cover is placed on the container body and moved into closed position.

The container is particularly characterized by the fact that'at-least a certain-= portion of the facing surfaces of thecooperating members are at least partially planar and that these planar surfaces, herein referred toas faces, are in face-to-face contact during the time the cooperating members are in closed relation ship and in sliding face-to-face contact during 4 the other member when the container is in closed position. The end members thus lend a neat appearance to the ends of the container, as illustrated in Figure 2, and also serve as stops to limit the forward motion of the cover member 22 when the container is closed.

A groove 25 is provided in the projecting portion of the end member 23 of the first cooperating member 2| and a pair of cooperating lugs 26 are provided on the end of the second'cooperating member 22 so as to engage the groove 25 when the container is in closed position. A similar groove and cooperating lugs, and 32, are provided at'the opposite end of the container. A tongue 29 extending from one planar contacting face'is received into a guide-groove 3| in the the movement of the cover to-openor'clo'se' the container, as will be hereinafter described; For

convenience, and without intending any limitation, movement of the cover with respect-to the container body to close the container is referred to as movement in' the forward direction, and

reverse movement isreferred to as movement in the rearward direction.

Likewise, the end of' the box, or parts thereof, appearing at the left in" Figure 1 will sometimes hereinafter be termed forwardly or forward end and the other end ceeds that the location Of these elements'may be reversed, if'desired, and,v furthermore, that the designation of either particular one of the' cooperating members as the container body and the other one as the container cover is purely arbitrary and for the sake of convenience only. Also, by way of simplifying the'descriptiom the relative movement of the cooperating members when the container is closed and" opened is re-' ferred to merely as the movement of the second cooperating member, or cover, into closed or open position-respectively. It will be further apparent that the shape of the interior" of the container is immaterial and the invention is notlimited thereby. In the drawing there isshownfor illustrative purposes a mahogany container adapted to house a safety razor during shipment and also to serve as a desirable storage container therefor between periods of use, this being but one of the many uses for which the container and closure means of the invention are adaptedi Referring now to Figure 1 a first cooperating member 2| and a second cooperating member 22 having planar contactingfaces 21 and, 28, respectively, are disposed so as to slide inface-toface contact upon one another. Each of the cooperating members is shown substantially rec tangular in cross-section, as in Figure 3, although it is apparent that they maybe of any other convenient shape, provided'they'are adapted to slide inface-to-face contact. Each of the members 2| and 22 is provided with an end member, ends 23 and 24 respectively; secured to,-- as by gluing, and projecting beyond the end'- surface of each respective membercso as to abutthe-end of opposite planar contacting face, by which relative longitudinal motion of the container parts is permitted but relative transverse motion prevented.

Referring now to Figures 5 and 8, the closure holding means comprises a pin-travel slot 33 located in a face 21 of the first cooperating member 2| in such a manner as to guide the travel -,of a pin 38, which protrudes therethrough and extends for some distance beyond the said face of the cooperating member. Below the pin-travel slot is a cavity or slider well 34 extending longitudinally through a portion of the member 2| and communicating with the bottom of the pintra'vel slot. A resilient means 35, such as a spring, is positioned in the slider well and serves to continuously'urge a slider 36, such as a wooden plug or piston fitted loosely into the cavity, forwardly in 'the'slider well. The pin 38 is secured in fixed position to the slider and thus travels in the pintravel slot as the slider travels in the slider well. The formation of the slider well and the assembling of the spring, slider and pin are effected conveniently before the end member 23 is secured to the first cooperating member 2 I.

A pin-retaining means is provided at the rearward end of-the pin-travel slot and may consist conveniently 'of a notch 39 .cut in the side of the pin-travel slot so as to provide a shoulder 40 constituting a square or even very slightly concave abutment for the retaining of said pin. Whenthe pin 38 is first moved rearwardly to the limit of its travel and then its upper end moved laterally with respect to its line of travel in such manner that the slider rotates slightly in the slider well, the pin engages the shoulder 40 and is effectively retained and prevented from traveling in a forward direction.

A'pin-engaging slot 4| (Figure 4) isprovided in the face of the second cooperating member, or cover, of the container and is so situated and aligned therein that when the twocooperating members-2i and 22 are in face-to-face contact, theportion of the pin 38 extending above the face of the first cooperating member 2| is received by the pin-engaging slot. The pin-en'- gaging slot 4| and the pin-travel slot 33 are furtheraligned so that when the cooperating members 2| and 22 are in face-to-face contact, they and-.22 areheldfirmly together; by the cooperat ing grooves and lugs-: and 2 6-;.,.3lt.and.32-lmen-.-- tioned. previously. When the second cooperating; member. 22 is slid: rearwardly, to disengage the:- cooperating. grooves and" lugs,. thepin: 38- is si multaneouslymoved rearwardly against theurgfing' of. the spring: and; due to theangle be.-- tween: the pin-travel slot 33" and the pin-engageing. slot M, the-sloping, sidevof the latter: urges:- the. pin sidewaysagainst the wall of? the pin-- travel. slot.. At the end'of: its travehthe: pin is: thrown. by such urging, into' the; notch 39- and thus into retaining engagement with theshoule der 48;..asshownin Figure 13.

When the pin has? reached. the. rearward 1 limit of: its: travel: and has. engaged? the pin-retaining means; the second cooperating memberxmay' be lifted away fromth'ez first cooperating member; the: pin remaining: int: position. to engage thez saidisecondcooperating member, orcover, when: it is. replaced; In. replacing: the second? coopcrating member'a-n'd closing the. container, it ise only: necessary to: place the two. cooperating members in face-to-face contact in-suchpositionr. that the: tongue. 29'. is received into the groove 3 iand: the pin: 33 projects'finto the pin-engaging. slot 4|. To enable this" latter to; be done easily: andaccurately; guide marks 42: of lFigurel.may. bev positioned: on: the: sides of? the cooperating: members; it thus being only necessary" to. see: that these guide marksiare. aligned-when the=cooperating: members are: placed; in face to f'ace' contact. A.. simple". forward: movement of the" second cooperating member22', by thezactionfon' lateral urging on. said pin of the rearward wall of: the? angularly placed; pin-engaging: slot 41'; then suffices" to-disengagetthe. pinirom the--pinretaining means'and'the cover is promptly urged' into closed. position bythe pin: pressing in a forwardv direction" on: the:' forward edge: of the pin engaging slot;

Although: the pin 38 isnormally prevented: by the wall of the pin-engaging slot from traveling forward f ar." enough to contact? the forward end of the pin-travel.slot,..the.endofrthe slotiserves effectively to limit". the forward travel of the in the slot; if the pintdoes accidentally become disengaged from the pin-retaining means while the cooperating members are separated, thus preventing dislocation of 'themechanism.

The pin 38' is preferably positioned" with its longitudinal axis in a plane substantially per pendicular tothe longitudinal dimensionof the face 21 of the first cooperating member- 21 asshownin' Figures 7 and'8'. It -need not, however; be perpendicular to -a l'ine'in the saidf'ace trans verse to the line of. travel of the pin-travel slot so that the pin assumes a definite outwardlyinclined position with respect to such-line, as

shown-in Figures" 10 and 11, since by so doing awider shoulder may be utilized as the pin-re taining means without rotatingtheslider 36' so"- far inwardly that said pin= extends into the in terior of the container.

but not necessarily, is aligned'on thecenter line=- ofthe pin-travel sl'ot'33i A-tongue corresponding to'the tongue S IWiIlthenbe caused to extend from the surface 2-8? to cooperate with the said guide' groove'.
