2 Claims.
This invention relates to coasters and similar supports. In particular the invention relates to coasters for containers, such as bottles, glasses and tumblers for beverages and other liquids.
1 Coasters .of this type have been made of a more or lessporous and particularly fibrous material, such as card board, felt or the like. Inexpensive coasters. are made of card board by casting or pressing paper pulp into a sheet of desired thickness, drying it and after solidification cutting or punching it into the desired shape. i Circular, oval or angular shapes are preferred.
In cutting or punching individual coasters from a larger sheet of material, such as cardboard or felt, ragged edges unavoidably result which inn pair the appearance of the coaster.
In order to reduce the amount of material used for an individual coaster, they were manufactured as thin as it was possible without impairing their required rigidity. A liquid spilled on such a thin coaster penetrates rather quickly to its bottom and is apt to damage the support on which it is placed, such as a table cloth or table. According to the invention a coaster of the type referred to above is inserted into a tightly fittingframe, preferably of thermoplastic material, such as cellulose ester and particularly acetyl cellulose-acetate. The frame is provided with two or more undercuts or projections on the inside firmly holding the. coaster in place.
A frame of that particular material is nonbreakable, insoluble in water and other liquids used as beverages, and in particular non-attackable by alcohol, acids and alkalis present in beverages.
A frame of this type can also be madesomewhat flexible in order. to facilitate insertion and removal of the coaster plate proper.
The frame is shaped so as to keep the coaster at a distance from a support which is sufficient to prevent a liquid penetrating the coaster to contact and thereby damage the support.
i The frame may also be provided with an upper rim which covers completely the rim of the coaster making ragged. edges invisible and thereby improving the appearance of the assembled coaster. 0n the upper side of the rim names or advertisements may be printed.
.The frame can be made of any desired color blending in with the coaster proper which further improves its appearance.
An object of the invention is therefore to provide as a new article ofmanufacture a coaster composed of a somewhat absorbent and rigid plate and a frame into which the plate is clamped,
the frame covering at least the side rim of the plate.
Another object of the invention is to provide as a new article of manufacture a coaster of cardboard or similar somewhat. absorbent and rigid, fibrous. material clamped into a frame having undercuts or projections slightly spacing the coaster plate from a support.
Still a further object of the invention is to provide as a new article of manufacture acoaster composed of a plate of cardboard, pressed into a frame of desired color and shape covering the rim of the plate, and provided with a number of undercuts or projections which due to their shape hold the plate firmly in place, clamp it within the frame, and space it from a support.
Still a further object of the invention is to provide as a new article of manufacture a coaster composed of a plate of cardboard, pressed into a somewhat flexible frame of moldable plastic material covering the rim of the plate and provided with a number of undercuts or projections which due: to their shape'permit insertion of the plate when the frame is somewhat slightly bent and clamp the plate firmly into place when inserted, and also space it from a support below.
Still another object of the invention is to provide as a new article of manufacture a coaster composed of a plate of cardboard of such a shape that it can be freely inserted into a frame pro- Vided with a number of undercuts or projections, and upon turning the plate within the frame the undercuts or projections clamp the plate firmly within the frame and space it from a support.
These and other objects of the invention will be more clearly understood when the specification proceeds with reference to the drawing in which Fig. 1 shows a top view and Fig, 2 a view from below with parts broken away of a coaster with frame according to the invention; Fig. 3 a crosssection along line 3-3 inFig. 1; Fig. 4 a crosssection through a part of an unbendable frame; Fig. 5 a crosssection through a part of a frame reinforced by an insert; and Fig. 6 a view from below with parts broken away of a coaster of particular configuration inserted and turned within a frame to be clamped by its undercuts or projections.
Like reference numbers identify similar parts in different figures.
Referring first to Figs. 1, 2 and 3, the coaster consists of a circular frame composed of a ring shaped top wall II), a cylindrical side wall H and undercuts or projections 12.
In this exemplification of the invention, a circular coaster plate l3 having a rim I4 is inserted into the frame. It is to be understood however that any other configuration of the coaster plate and therefore frame, such as an oval, angular etc. configuration can be used, without deviating from the underlying idea of the invention; 7
Three undercuts or projections l2 are shown in this example. It should beunderstood that a smaller number, two as a minimum, or a larger number can be used; the undercuts are to be spaced from each other so as to facilitate manufacture and insertion of the coaster plate. They are to be provided at such places on the inside of side wall [I that the coaster plate I3 is properly held in position.
As to be seen from Fig, 3, the undercuts or projections I2 are provided with a sloping or inclined upper surface l5.
Coaster plates produced in the way described above, i. e. cut or punched out of a solidified larger sheet of paper pulp or other fibrous or non-fibrous material, vary slightly as to thickness due to unavoidable inaccuracy in manufacture. Furthermore, the diameters vary slightly due to unavoidable inaccuracies in cutting or punching. Sometimes also slight variations as mentioned above are brought about intentionally so as to vary the weight and cost of the coaster plate.
Taking a sheetlike cardboard material from which the plate is cut, its thickness may be e. g.
its' diameter may vary er plates the thicknessand diameter of which may also vary within the small range-exemplified above, the sloping or inclined surface I5 is provided for. When the coaster plate is pressed into the frame, the plate, due to a slight resiliency, slightly gives and can be clamped between the sloping surface t5 and the inner surface IB- of top ring Iii. It will be appreciated that due to the wedgelike action of the sloping surface [5, a somewhat thicker or thinner coaster will be equally clamped between those surfaces. It is further to be understood that the distance between those surfaces is to be chosen sothat a coaster of any thickness within a contemplated range will securely be held in place. The inner diameter of the side wall H is to be chosen so that coaster plates of greatest diameter fit into the frame; though plates of somewhat smaller diameter than that of. the frame will not con tact its side wall, they will be held firmlyin place by the wedging action of the projections l2.
In Fig. 3 a coaster plate I3 is shown in full lines and another plate [9' of slightly different thickness and diameter in dotted lines to illustrate the above elfects.
In order to put a coaster plate in place, the frame as well as the coaster plate are slightly bent so that the diameter of the plate 'is somewhat reduced where the plate is to be slipped above the projections l2 while the latter by slightly bending the frame are bent outwardly and/or downwardly. After the plate has been slipped into the frame above projections I2, the pressure for bending the plate and frame is released and they resume their original shape so that the sloping surface I5 clamps the rim of the plate firmly against the inner surface l'6 of for flexibility conforms with in-expensive manufacture.
The upper side of top ring 10 is flat so that i printing or stamping can be easily done on it;
for instance the name of the manufacturer, the 7 dealer, or an advertisement for a beverage can thus be printed on or pressed into this conspicuous part of the coaster frame.
As can be further seen from Fig. 3 the lower surface H of the undercut or projection 12 is somewhat spaced from the lowermost surface l8 of the frame. This is an additional feature of the invention securing desired spacing of the pressed in plate 13 from a support. However,
such spacing of the coaster plate from a support can also be accomplished" if the lower surface I! of projection l2 lies flush with surface I8 of the frame, or even if projection 2 with its lower surface H projects somewhat downwardly beyond surface l8 toform a kind of foot.
It will be appreciated that the coaster plate thus clamped into the frame is firmly held in position. It can easily be exchanged for another plate, and the frame therefore be used over and over again for a long period of time.
All practical differences: or variations in di mensions of the frame and thecoaster plate in mass production are taken care. of by the shape of the projections or undercuts.
Referring to Fig. 4, there a cross-section is shown through a frame provided with undercuts l2 and top-ring N0 of the same purpose and principal design as in Fig. 3. Side wall HI is,
. however, considerably thicker than top-ring H0 or side wall H in Fig. 3 in order to reduce or prevent flexibility of the frame. It has been found that in manufacturing frames of great flexibility the 7 frames sometimes warp when ejected from the molding machine. In order to save reshaping them in a press, by slightly increasing the thickness of the side wall such warping can be avoided. However, also very flexible frames reshape themselves satisfactorily when the coaster plate is inserted, and reshaping them in a press does not materially increase the cost in mass production.
Fig. 5 shows another feature of the invention,
which prevents or removes warping of the frame. According to this feature of the invention an expansion ring I88, preferably of metal, is inserted inside of side wall I89 and serves to stiffen and straighten out the frame before the coaster plate is inserted. Expansion ring I08 may either be inserted in the mold and the frame'molded around it, or it may be inserted into the molded frame after the latter has-been ejected from the mold.
In cases where stiffer frames are used, such as shown in Figs. 4 and 5, it is preferable to apply a coaster plate as shown in' Fig. 6. This plate is partly out along lines H5, and can he slipped into the frame in aposition where projections l2 register with the cut-off portions of the plate. After fully inserting the plate into'the'frame the former is turned into the position shown in Fig. 6. There full portions of the plate are aligned with the projections l2 and readily clamped by them against theinterior surface of top-ring II) which covers the cut-off portions of the plate so that they are invisible from above when the assembled coaster plate is used.
Coaster plates H3, of a shape as shown in Fig. 6, can easily be manufactured by punching or cutting them out in final shape as shown from the sheet of cardboard or other preferably porous material. Though the cut-off portions may be of any other shape and design so as to permit slipping of plate 13 over the projections l2 substantially without bending the frame or coaster plate, the shape shown is preferable because the dies necessary for cutting the plate along lines H5 can easily be made and arranged in the punching or cutting machine.
As pointed out above, the invention substantially consists in a frame which covers the rim of the coaster plate and also keeps it in some distance from a support, into which the coaster plate is clamped so as to take care of slight variations as to thickness and diameter of the coaster plate. It will be appreciated, however, that the wedging action produced by the sloping surface of the undercuts or projections can equally be obtained by making the inner surface of ring In sloping in opposite direction to the sloping surface of projection l2, and that both arrangements can be combinedwithout deviating from the idea underlying the invention which is to be derived in its broadest aspect from the appended claims.
