PAPERBOARD PROTECTOR FOR PAINT BRUSHES Filed Aug. 23, 1949 h INVENTOR- Ml LIAM A7.- favaLe-e,

QLJZA ATTORNEYS- Patented sept. 9, 1952 PAPERBOARD PROTECTOR PAINT BRUSHES William A. Ringler, Wayne, Pa., assignor to The Gardner Board and Carton (lo liliddletown, Ohio, a corporation of Ohio Application August 23, 1949, Serial No. 111385 My invention relates to a knock down or collapsible paperboard structure designed for the protection of the bristle portion of paint brushes v or the like.

Objects of the invention are the provision of improved structures of this class which nevertheless are simple in form and economical to produce, the provision of structures capable of repeated reuse, and not liable to destruction through repeated opening and closure, and the provision of structures giving enhanced protection to the article of merchandise with which they are to be used.

It is an object of my invention also to provide a structure which, where desired, may be maintained in semi-erected condition in the absence of the article, facilitating the reinsertion of the article therein.

It is an object of the invention to provide a paint brush protector which is suitable not only for use as a protection to the paint brush during initial shipment, storage and the like, but which also may be employed, as has hitherto been suggested, in preserving the bristles and molding the shape of the bristle assembly of paint brushes which have been used and cleaned. It is an object of the invention to provide a tight package for the bristle portion of a paint brush, resistant to the infiltration of dirt and dust. It is an object of the invention to providea paint brush protector which is simple in manipulation, and which has other valuable features hereinafter set forth.

These and other objects of the invention which will later be indicated, or which will be apparent to one skilled in the art upon reading these specifications, I accomplish by that construction and arrangement of parts of which I shall now describe an exemplary embodiment. Reference is made to the accompanying drawings wherein:

Figure l is a plan view of a cut and scored paperboard blank .produced in accordance with my invention.

Figure 2 is a partial perspective view of the blank after an initial step of erection.

Figure ,3 is a partial pers ective View of the protector in one form of the erected condition, ready to receive a paint brush.

Figure 4. is a partial sectional view taken along the section line 6- 4 of Figure 3.

Figure 5 is a perspective View of the erected structure containing a paint brush, but prior to closure.

Figure 6 is a perspective view with parts in section showing the closed protector containing the paint brush.

Referring first to Figure 1 in which solid lines indicate lines of cut, dot-dash lines indicate lines of score, and dashed lines indicate lines of weakening, I have shown a paperboard blank having a main panel forming the front panel of the structure. To the sides of the main panel there are articulated triangular

side wall panels

2 and 3 Claims. (Cl. 206-15.1)

2 3, to the outer edges of which closure panels, 5 and 6 are articulated. These closure panels "may be made in Various shapes, .but are conveniently made substantially triangular as shown, ands'o proportioned that their outer corners will overlap in the erected structure. v

To the upper end of'the main panel I I articulate an end wall panel I. This panel bears an inner end wall extension 8 having a flap 9.. Diagonally scored webs it and II .interconnect the ends of the

side wallelernents

2 and 3. respectively and the ends of the end wallelement I.

To the lower edge of the main panel I I articulate a second panel l2of substantially the same size. This panel forms, a rear protecting (panel for the paint brush. It bears at. its end a tuck fiapl3. L Cuts formingincomplete ellipses are formed in the end Wall 7 and its extension 81 The ellipses are completed by score lines as. shown, and the configurations are oppositely directed as indicated to form a tab J4 or 15 in each of the elements 1 and8, so positioned as to coincide when the inner end wall element is folded inside cutting and scorinsl ress operations from suitable boxboard or paperboard, previously printed as may be desired. The board may beheav ily sized or otherwise treated to render it moisture resistant, to prevent weakening when a 'previously used and washed brush is placed there in. It may also, if desired, be treated sofas to be resistant tothe solvents of paints and enamels with which the brush is to be used, or to "solvents and solutions employed for cleaning brushes.

Where the structure is made of very heavy'pape'rjboard or boxboard for added strength, certainof the score lines may advantageously be weakened by cutting or slitting or perforating, as for example the diagonal score lines I9 and 20 ,of the corner webs l0 and H, and the score 21 by. which the flap 9 is articulated. to the end wall extension 8.

Figure 2 shows my structure with the

side wall elements

2 and 3 erected at right angles tothe main panel I. In use, the end wall extension 8 will be folded over inwardly of the end wall element 1. When this is done, and when the tab elements l4 and I5 are depressed to the outer side of the end wall I, the engagement of the tab M in the orifice left by the tab IE will serveto maintain the end wall and end wall extensions in erected condition. This relationship willbe evident from Figures 3 and 4. The depressionof the tabs l4 and i5 outwardly will also provide an webs I and H.

The protector may be assembled about a aint brush in various ways. For example, the inner end wall extension 8 may be folded over inside the end wall I, and the tabs I4 and I passed through to the outside. Then the handle 23 of a paint brush of the size for which the protector is designed may be passed through the opening 22 left by the tabs l4 and I5, and the bristle portion of the paint brush laid against the main' This will result in erecting the end wallpanel I. structure with respect to the main panel. The

side walls

2 and 3 may then be erected, the webs I0 and I I folding bellows-wise and lying in folded condition either at the top of the bristle portion of the brush, or alongside it. The panel 12 will be folded over against the opposite face of the bristle portion of the paint brush, with the flap I 3 tucked down inside the end wall. The closure flaps 5 and 6 will be folded over on top of the panel [2, and snap fastener elements 15, H interengaged. This will result in a structure such as is. illustrated in Figure 6.

In an alternative erecting procedure, the

side wall elements

2 and 3 may first be brought upwardly at right angles to the main panel I, after which the end wall element I is folded upwardly, accompanied by the bellows folding of the webs l0 and II. Then the end wall extension 8 may befolded over inwardly so as to cover the folded The passing of the tabs l4 and through to the outside will serve to lock together the end wall 1 and the inner end wall extension 8, giving the erected structure which is illustrated in Figure 3. With the panel l2 coplanar with the main panel I, the brush may be inserted as illustrated in Figure 5, and then the structure closed. as hereinabove described. In the erected and closed structure the flap 9 lies inside of nd parallel to the main panel I.

It will be understood that the structure herein described not only serves as a protection for the paint brush during initial shipment, storage and the handling incident to merchandising, but also that the purchaser of the brush will retain the protector and will return to it a used brush which has been thoroughly cleaned. In this instance the protector not only prevents damage to the bristles, but molds the bristle assembly into a tapered shape suitable for preservation and for future use.

Modifications may be made in my invention without departing from the spirit of it. Having described my invention in an exemplary embodiment, what I claim as new and desire to secure by Letters Patent is:
