11 Claims, 11 Drawing Figures CASE SEALED BY A COVER, A PROCESS FOR THE MANUFACTURE OF A CASE COVERED BY A FOIL AND EQUIPMENT FOR EXECUTING THE PROCESS The invention relates to a case for cosmetic or pharmaceutical products, to a process for manufacturing a filled case having a foil and a cover, and apparatus for carrying out the process.
It is the fashion of the times when selling personal wares such as cosmetic or pharmaceutical goods to seal the goods in such a manner as to draw the attention of the buyer if the ware comes into his possession previously touched. The present invention solves this problem by covering the case of the invention with a foil.
Accordingly, the present invention provides a container for pharmaceutical or cosmetic products comprising a case having an open end defined by an upper rim, a foil fastened to the case and covering the open end, the foil being stretched taut and smooth over the open end to provide a substantially flat surface, and a cover screwed onto the case and having a stamping in sert which depresses the foil below the rim in taut condition. The foil acts as a seal to indicate that the contents of the container have not been touched or used. If the foil is damaged or removed, the buyer is informed that the contents have been touched.
The present invention also provides a process for closing the open end of a filled case having a rim comprising fastening the foil to the rim of the case, and screwing a cover having a stamping insert onto the case to stretch and smooth the foil onto the case.
The present invention also provides an apparatus for closing the open end ofa filled case comprising a slider on which the case is seated; a first adjustable stop to set the position of the case in the seat, a second stop movable against said first stop for keeping the case in place between the two stops. a vertically movable sealing head for fastening the foil on the case. and a switch which can be activated by the slider when the case is clamped between the two stops and operate the sealing head.
DETAILED DESCRIPTION OF THE INVENTION The accompanying drawings illustrate an example of a preferred embodiment of the invention and, together with the description. serve to explain the principles of the invention.
FIG. I of the drawings is a perspective view. partially in section, showing a case in the filled state and with a wrinkled foil mounted at the edge of the case;
FIG. 2 shows a partial sectional view of the case cover for the embodiment of FIG. I.
FIG. 3 shows a partial sectional view of a stamped insert which is slid into the cover;
FIG. 4 is a top view of an apparatus for centering and locating a filled case as in FIG. I underneath a sealinghead in order to deposit and fasten the foil on the case edge;
FIG. 5 is a section through the apparatus of FIG. 4 taken along lines 55; and
FIG. 6 is an elevation view similar to FIG. 4 with parts removed.
FIGS. 7a. 7b. and 7( show respectively enlarged views of area 7-7 of FIG. 3. illustrating a shaped. U-shaped. and rounded cross-section of the stretching and sealing ring.
FIG. 8 shows a partial sectional view of a stamped insert which is slid into the cover having a plurality of stamping rings.
FIG. 9 shows a partial sectional view of a stamping insert which is slid into the cover having a stamping bulge.
Referring to the drawings, there is shown in FIG. 1 a case I provided with an outer thread 2 at its upper end and an upper sealing edge or rim 4. A foil 6 is seated on upper sealing edge 4. Foil 6 may be a laminated aluminum foil, that is. one coated with a synthetic material and is provided with a tear-off flap 7. When the aluminum foil is in a slack or unstretched state, the foil 6 has an aged, wrinkled look as shown by its cross-section 8 in FIG. 1. After the foil is stretched, as explained in greater detail below, the surface of foil 6 will be smooth, as shown by its cross-section 10. In contrast to the unstretched foil, the stretched foil is provided with a stamping offset 11.
A cover 22, shown in FIG. 2, has an internally threaded side 23. A stamping and sealing insert 13 (FIG. 3) is positioned in cover 22. Insert 13 is provided with a deposition disk 15 which rests upon the inside cover surface. and also with an outer holdingedge 16 for centering and holding insert I3 in cover 22. The insert I3 is further provided with a support rim 18 to be laid on upper sealing rim 4 of case I. Support rim I8 is provided with a contiguous compression ring 19 and a flat inner surface 20 recessed from ring I9. Compression ring 19 acts as a stretching and sealing ring.
In operation, case I is filled with the appropriate product. and then a foil 6 is laid on upper rim 4 so as to cover it. Subsequently. foil 6 is fastened to the upper rim 4 of the case by changing its shape (deformation) or by gluing or by hot sealing. The inside section of foil 6 covering the open end of the filled case now exhibits a cross-section 8 with interfering folds. Cover 22 is now screwed on case I and stamping and sealing insert 13 in cover 22 presses against foil 6 by means of its compression ring I9. During further screwing of cover 22, the outer rim follows the stamping setoff I1 and stretches foil 6 into the case I until foil 6 is stretched flat and completely smooth. Foil 6 is now completely formed or shaped with respect to upper rim 4 and covers the opening of case I. If now the user removes cover 22 from case I, he will observe that it is sealed by a neatly taut foil 6 and that the contents have re mained untouched. The packing is intact and the con-- tents are untouched. Following removal of foil 6, stamping insert I3 is used as a seal.
FIGS. 4, 5 and 6 show an apparatus for quickly, easily and manually centering cases to be sealed or covered opposite a sealing tool. This apparatus comprises a housing 26 having a front clearance 28 and a back clearance 30. Lateral guiding bars 32 guide a slider 42, and lateral guiding bars 34 spaced from the bars 32 guide a rear stop 35 which, depending on the size case 1 or of its diameter. will be positioned on bars 32. A movable carriage 36 with a micro-switch 37 is located in the back clearance 30. Carriage 36 may be shifted and fastened at a fixed distance with respect to a stop 38. as shown. The rear stop 35 is provided with two lateral slots 39 from which extend bolts 40 providing guidance along bars 32. Stop 35 may be fastened by means of nuts not shown. Slider 42 has a base 43 for seating case I and a handle 44. Stop 38, which serves as a motion-limiter for slider 42 and simultaneously as an actuator for switch 37, is mounted to the bottom of base 43 of slider 42. Slider 42 has guiding bolts 46 and carries a front stop 45 which has guiding slots 47. Guiding slots 47 receive guiding bolts 46 and front stop 45 is movably mounted on guiding bolts 46 on slider 42. Helical springs 51 in boreholes 49 of the front stop 45 and in boreholes 50 in slider 42 press the front stop 45 into its rear terminal position.
A centering index mark 53 is located laterally, corresponding to the center of the seal head during hot sealing or gluing by the sealing head when deforming the foil. Marks are furthermore located at the guiding bars 32, for the sizes of cases 1, by means of which the rear stop 35 may be shifted and also be fastened by means of stop-nuts 40.
The equipment operates as follows: After the case 1 is filled, it will arrive at base 43 of slider 42. Rear stop 35 already has been set according to case size. The sealing, gluing or forming devices are also set according to case size. Slider 42 then is pushed with case 1 on it so that case 1 is moved and forced against rear stop 35. Slider 42 will be pushed further until it contacts front stop 45 by which means it will be centered, that is, placed precisely underneath the sealing head. The fur ther motion of slider 42 compresses springs 51 so that by their compression, front stop 45 will be pressed against the case which then will be solidly held between the two stops 35 and 42. During this motion of slider 42, the corresponding surface of stop 38 reaches the sensor of switch 37 and depresses it against the switchhousing to close the circuit to the sealing stamp. Upon closing the circuit. the sealing stamp is lowered on foil 6 lying on upper rim 4 of case 1 and connects the foil to the case. One can also use a die or a compression head instead of a sealing stamp for adhering the foil to the rim of container 1. The return stroke of the sealing stamp occurs after sealing or fastening of the foil 6 to case 1 in automatic fashion and without further motion of the slider. The slider is then withdrawn and the apparatus is ready to receive the next case which will be subjected to the same process.
The equipment described is of extremely simple design and allows rapid processing for manual labor where there are small production runs. Obviously, automatic filling and sealing or foil-closing stations must be provided, such as are well known is design in practice, if production is large.
One may also seal the case with pre-stamped foils. Pre-stamping may occur by means of radial corrugation or by means of another cross-sectional shape or relief.
The stamping or compression ring may be in the shape of a V, or of an U or rounded as illustrated respectively in FIGS. 7a, 7b and 70. One may also make use of several stamping rings, 19 for instance. concentrically arranged stamping rings shown in FIG. 8. Also, the foils may be provided with tear-flaps. A stamping bulge 21 as shown in FIG. 9 may project at the stamping center if this method is used.
The invention in its broader aspects is not limited to the specific details shown and described and departures may be made from such details without departing from the principles of the invention and without sacrificing its chief advantages.
