SPECIFICATION formingpart of Letters Patent No. 597,726, dated January 25, 1898.

Application filed January 13, 1896. Serial No. 575,206. (No model.)

To ctZZ whom it may concern:

Be it known that 1, CHARLES WILLIAMLOv ELL, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Mailing-Boxes and other Receptacles, of which the following is a specification.

This invention relates to boxes and receptacles, and especially to boxes for packing bottled liquids and other articles for safe shipment through the mails and for likepurposes.

The invention aims to provide improvements which are especially applicable to boxes for mailing liquids in bottles and aims to provide a box sufficiently strong to protect a fragile bottle against breakage, sufficiently tight to prevent leakage of the contents of the bottle in case of accident, and a box which shall be cheap and light of construction and easy of manipulation.

In carrying out the invention in its preferred form the box is made internally absorbent and externally impervious to moisture, the cover makes a leak-tight joint with the body, an improved-separable connection is provided for fastening the cover and body together, and a cushioning and absorbent material is disposed in the spacesbetween the inner walls of the boxand the vessel it carries. Other features of improvement are also provided.

In the accompanying drawings, which show the preferred form of my invention, Figure 1 is a side elevation of a mailing-box embodying my improvements; and Fig. 2 is a vertical axial section thereof, the bottle or other liquid-holdin g vessel being shown therein in elevation.

Referring to the drawings, let A indicate the body of a box, B thecover thereof, and 'O the bottle or other vessel packed therein. The exterior a of the body is preferably impervious to moisture. The exterior I) of the cover is likewise impervious, these external surfaces being continuous and uninterrupted around the sides and ends of the body and cover. The body is a cylindrical cup-shaped member having side walls 0 and bottom walls (Z, united by a curve B. The cover is also cupshaped, having cylindrical side walls f and flat top g, united by a curve It with the side walls. The cover and body fit together, the joint being preferably eflfected by providing a socket '6 in the body, which receives a cylindrical neck j on the cover. The top edge is of the body is opposed to the bottom edge l of the outer wall of the cover, and between these edges is a thin ring m, of rubber or other suitable packing or expansive material,

which may be slightly compressed as the cover is seated on the body, so that, if desired, there may be a tendency for slight separation of the body and cover.

A fastening or clasp D for holding the cover on the body is provided, and an additional fastening or catch E for insuring against their separation is also preferably employed. The fastening D is best constructed as a bayonetjoint or L-shaped socket, recess, or groove with a vertical leg n and a transverse and slightly outwardly undercut or other suitable portion, as the inclined leg 0, which groove is formed in, on, or near one of the parts of the box, as the wall 0 of the body, and is re ciprocal to a projection or other suitable provision, as the stud 19, carried on or by the other of the parts of the box, as the neck j of the cover. The studs 19 and groovesn 0 are shown as duplicated at diametrically opposite sides of the box, and when the cover is passed into the box with its studs in the vertical grooves and pushed inwardly until its studs are opposite the transverse groove 0, the packing m must be slightly compressed before the studs can pass below the downwardly-projecting corners q of the grooves, as these corners are slightly below the remainder of the transverse portion of the grooves. hen the studs are below. these corners, a slight relative rotation of the box and cover will suffice to bring the studs into the inner ends or holding portions of the grooves, where the expansive tendency of the packing m will assist in holding them. The fastening E serves as an elastic catch, holding the clasp D from accidental loosening, and as shown is a band, preferably an elastic endless rubber strap 7", the bends in which are fixed to the body A in any suitable manner, as by means of the staples s, which are driven into the side walls This strap is stretched up over 0 of the box.

the cover, passing across the top of the latter. For holding it the cover has notches or equivalent provisions t on its upper corners. The strap is disposed slightly at one side of the studs 1) and of the end of the part of the grooves, so that when the stud is home in the grooves the strap will lie at rear of the stud I when it is moved in position, and will thus prevent any loosening movement of the stud in the groove, as shown in Fig. 1.

The joint between the box and cover is made leak-tight also by coating the inner face of the socket t' and the outer face of the neck j with paraflin or other suitable sealing material of sufficient softness to permit the neck to be passed into the body and removed therefrom without too great resistance.

The outer portion of the body and of the cover may be made of any suitable material, but I prefer to mold these parts of papiermach or other light fibrous material of sufficient strength, which may be rendered impervious to moisture in any suitable manner, as by applying a coating u of impervious material to its outer walls.

I prefer to provide immediately within the body a cylinder F, of strawboard, paper, or other sufficiently stiff material, which cylinder, if made of strawboard, will have the advantage of being highly absorbent of moisture and of swelling when moistened. This cylinder is a close fit with the inner sides of the walls 0 of the box, and is preferably I shorter than these walls, having its upper edge i) at the bottom of the socket or mouth 1. of the box and its lower edge to near the bottom wall d of the box. Between this edge and the bottom wall I prefer to locate a flat disk :30, of strawboard or other suitable absorbent or strengthening material, which reinforces the sides of the body against diametric strains, strengthens the bottom wall d, and acts as an end absorbent for moisture. The interior of the cover is similarly constructed, having a like cylinder G, which, however, is longer than the side walls of the cover and has its lower end 3 projecting a considerable distance beyond the face Z of the cover. From this face outwardly the cylinder Gr serves as the neck for the cover. When in position on the body, the neck lies with its end y in close proximity to the end 2) of the cylinder F, and

when the cylinders are swollen by moisture these end faces immediately are forced together and make a tight joint. The upper end of the cylinder G terminates at z, slightly below the top Q of the cover, and between this end and top there is inserted a strawboard or other disk H, which serves the same purpose for the cover as does the disk :0 for the body.

The box is preferably somewhat larger in ternally than the vessel to be packed in it, and its internal space is utilized for the reception of absorbent and cushioning material. This material may be of any suitable or desired character and is disposed within the box as desired. I prefer to use cotton to arrange this so that it will be held in position to leave a socket for the bottle or other vessel substantially conforming to the shape of the latter. This socket is formed partially in'the box and partially in the cover and the space between it and the walls is filled with absorbent material.

Preferably a perforated bibulous paper I is fastened within the box in' the shape desired for the socket in the body portion, and cotton'J is filled in to the desired quantity between this paper and the walls of the body. This paper is pasted at its upper edge a to the cylinder F, nearthe end '0 thereof. In the cover a similar bibulous paper I is employed pasted at its lower edge at B to the lower edge of the cylinder G, and between this paper and the walls the desired quantity of cotton J is inserted. Preferably the division between the body and cover is made at some prominent or large part of the vessel to be packed. In the'examp le shown the division is at the junction of the neck and body of the bottle 0, so that the bottle-body is carried in the body of the box and the neck in the cover of the box. Thesocket K in the body is accordingly shaped to substantially'fit the bottle-body, while the socket K in the cover is contracted to substantially fit the neck. The upper face a of the wall I will bear 011 the cork of the bottle, the lower face (1 of the wall I will receive the bottom of the bottle, and the face 6' of the wall I will be over the neck or shoulder of the body of the bottle, so that the latter will be firmly embraced by the interior of the box, but will be held by the yielding inner lining thereof, so that the shocks to which the box is subjected will be cushioned before reaching the bottle. If a bottle should break or leak, the fluid flowing from it will be immediately drawn by capillary action into the absorbent cotton, which of itself will best be proportioned in quantity to an amount sufficient to entirely absorb the contents of liquid held by the vessel to be packed in the box. From this cotton the moisture will be communicated in part to the absorbent cylinders F and G and the top H and bottom 00, and these will be immediately expanded against each other and against the inner walls of the body and cover with sufficient force to make leak-tight joints at their junctions. Should any moisture permeate through the cylinders, the impermeable outer walls will prevent external dampness. The paraffin between the socket i and neck j and the packing-ring m will prevent any leakage prior to complete absorption of the liquid escaping from the bottle.

In use the bottle will be first placed in the body, whereupon the cover B will be applied to the latter, pressed home, and then fastened in position. In the construction shown the rubber band 0' will be turned down to the side until the cover has been passed inwardly and turned until its studs are home in the grooves. Then the rubber band will be stretched up over the top, snapped into its grooves i, and seated in rear of the studs 1), so that they cannot turn backward. The boX can then be shipped by mail, express, or otherwise without danger of accidental opening. To open it, the band r should first be freed from the cover, when the latter can be pressed inwardly and turned to bring its studs 1) into the upright legs of the grooves, whereupon it can be drawn out. In many instances the fastening D or the fastening E can be alone relied on; but I prefer to employ both for the greatest security.

It will. be seen that my invention provides improvements which can be readily and advantageously availed of, and it will be understood that the invention is not limited to the particular details of construction, arrangement, or combination set forth and shown as constituting the preferred form of the invention, but that it can be employed, in whole or in part, according to such modifications as circumstances or the judgment of those skilled in the art may dictate without departing from the spirit of the invention.

The shape of the box can be varied to adapt it to the shape of the bottle or other vessel to be packed, and'the construction of the inner casing and the arrangement of the absorbent material can be modified to suit the shape of the box and the requirements of use.

By makingthe fastening between the cover and body an undercut fastening, so that the holding portions of the recess and projection when in engagement in the fastened position require a preliminary releasing operation before they can be disengaged to permit the separation of the cover, great security is attained against accidental opening of the box. Any construction of recess and projection can be employed and any means for catching the fastening against accidental displacement can be employed. In the construction shown the catch E is utilized for this purpose, and in addition the tendency of the box and cover to separate is also utilized. In this construction several portions of the box incidentally contribute to produce this separable tendency.

The elastic packing between the cover and body, no matter where placed, may be conipressed as the fasteningis passing to the holding position, so that its expansion will tend to resist movement of the parts when they have reached the holding position, as such movement would necessitate a slight compression of this packing. In case of Wetting the expansion of the inner tubes draws the fastening into tighter en gageinent. The compression of the fibrous material J and J between the ends of the bottle and the adjacent ends of the box and cover also tends to separate the latter and add to the resistance to be overcome in m ovin g the cover inwardly until 1.
