Dec. 24, 1963 T. HAUSER PACKING FOR AMPOULES OR THE LIKE Filed June '12, 1961 1N VENT OR. 4 20 Theolon Hansen mm (7- MM A TTORNEY United States Patent Office 3,115,247 Patented Dec. 24, 1963 3,115,247 PACKING FOR AMPQULES- OR THE LIKE Theodor Hauser, Hans Zum Freulereck, Nafels/GL, Switzerland Filed June 12, 1961, Ser. No. 116,616 Claims priority, application Switzerland June 10, 1960 6 Claims. (Cl. 206-65) cardboard in the manner of the known folded packs, are
capable of efiiciently protecting the glass ampoules against lateral shocks while particular measures are required to absorb impacts on the bottom or top surface, ie in the longitudinal direction of the ampoules. A known method of solving this problem in packings of this type is to provide a resilient intermediate insert on the inside of the bottom and top surfaces which is formed by a pair of opposite tongues integrally cut which are folded against one another and of which the free ends are so connected that the lengths of pairs of such tongues between the folded point and the connection are greater than the distance between the folding points. This solution, however, presents the disadvantage that the tongues to be integrally cut out will laterally extend from the actual blank width when unfolded, so that the necessary width of the material is more than twice that of the finished width, which results in comparatively large pieces of-waste material in the cutting operation.
The present invention is designed to eliminate these disadvantages. It is characterized by the fact that the bottom and top surfaces are provided, underneath and above the said perforations, with inwardly embossed indentations in the sheet material and that means are provided for centering the ampoules relative to these indentations.
Accordingly, it is an important object of the present invention to provide an improved package for supporting articles, particularly ampoules or the like, in a safe and reliable manner.
A further important object of the present invention is to provide an improved blank construction which can be folded into a carton or package for articles, particularly for ampoules or the like, in a relatively simple and quick manner, and is particularly adapted for packaging such articles by semi-automatic or fully automatic processes.
Another important object of the present invention is to provide an improved blank structure for a carton which can be manufactured and assembled in an efficient and economical manner.
Still a further important object of the present invention is to provide an improved blank which can be folded into a carton without requiring adhesive material for joining together the panels of said carton.
Another important object of the present invention is to provide an improved blank and carton formed from such blank which can safely support articles therein, such as ampoules or the like, is provided with means defining shock absorbing surfaces for said articles, as well as means permitting aligning and support of said articles within said carton, even if the outer contour of said article is not uniform.
A further object of the present invention is to provide an improved blank and carton structure including means for supporting the article receiving panels of said carton without requiring the use of adhesive material to assemble the blank into carton form.
An embodiment of the packing according to the present invention is shown in the drawing and will be described in greater detail below. In the drawing,
FIG. 1 shows the packing unfolded in the form of a blank;
2 is a perspective view of the as-folded packing; 3 is a vertical section thereof;
4 shows an individual indentation seen from the outside at a larger scale;
FIG. 5 is a cross-sectional view taken along line VV in FIG. 4, and
FIG. 6 shows an article support and aligning perforation with the ampoule inserted and viewed along the axis of the ampoule.
The design of the packing is shown in FIGS. 1 through 3. The shape of the unfolded box or blank formed of a piece of light cardboard cut and prefolded in one operation is shown in FIG. 1. The fold lines are shown in broken lines. Arranged in the central portion of the flat blank are the end tongue or wall 1, the top wall or surface 2, the rear wall or surface 3, the bottom wall or surface 4, the front wall or surface 5, the intermediate wall or surface 6, the connecting wall or area 7, the intermediate wall or surface 8 and the supporting wall or tongue 9. These surfaces or panels are bent along the prefolded lines according to FIGS. 2 and 3 so that the intermediate surfaces 6 and 8 will be located in parallel relationship between the bottom wall surface 4 and the top wall surface 2. Laterally of the central blank portion are the side walls It) with the closing tongue 11 and the side supporting tongues 12 and 13 which lend the folded box or carton sufficient rigidity and hold the intermediate wall surfaces 6 and 8 in position. Arranged at the side walls 10 is a further tongue or side flap 10a of which the height is the same as that of the supporting tongues 9. If the tongue 10a is bent slightly inwards of the box as seen in FIG. 2, they will serve as stays between the surfaces 4 and 8 so that the surfaces 7 and 3 need not be glued.
The tongues 10a are effectively inwardly foldable rear base flaps in the unit of FIGURE 2. They result from the side walls It) being cut, as shown, first upwardly from the lower edge thereof and then inwardly to the adjacent side fold line. The height of the fiaps 10a parallel to such side fold lines, as also shown, is equal to the difference in height of the front wall 5 and the connecting wall 7, such difference in height corresponding also to the height of the supporting tongue 9.
The aforesaid tongues 12 and 13 can properly be regarded as providing side supporting tongue means. Each such means is respectively hingedly connected to an opposite side edge of the second intermediate wall 8 along a fold line. Consistent with this definition, each of the tongue means includes a main section 12 and a pair of inwardly foldable top and side flaps 13.
In order to accommodate the ampoules 14, the intermediate surfaces 6 and 8 are provided with receiving apertures or perforations 36 arranged in alignment above one another and into which the ampoules are detachably inserted. The fragile ampoules are very efficiently protected against lateral impacts by the rigidity of the material. In order to efiiciently absorb impacts in the direction of the ampoule axis the bottom wall surface 4 adjacent to the rear ends of the ampoules and the top wall surface 2 adjacent to the ampoule front ends are provided with inwardly embossed indentations 20 preferably integrally formed in the sheet material. These indentations are located underneath and, respectively, above the aligned apertures 36, and their configuration is shown in FIGS. 4 and 5. In order to increase the rigidity of the cup 3 type indentations 2% they are provided with four radially arranged and embossed reinforcing ribs 21.
In order to ensure the cushioning and resilient action of said indentations 29, the ampoules 14 must have their longitudinal axis centered on the center of these indentations as shown in FIG. 3. As such, circular perforations adapted to the diameter of the cylindrical ampoule portion in the surfaces 6 and 8 could ensure such a centering action. However, the diameter of the ampoules differs within certain limits determined by the tolerances in manufacture, and it would be highly uneconomical to adjust the diameter of the perforations to that of the ampoules. In order to ensure perfect centering despite this fact, the apertures 30 are provided with preferably four radially directed ribs 31 which taper in the direction of the center. At least three such tongues are required per aperture in order to achieve centering. These ribs or tongues 31 are bent when the ampoules are inserted and will then rest on the wall of the ampoules. FIG. 6 clearly shows that this configuration of the perforations 36, which resembles a Maltese-cross star wheel or clover-leaf, or of the tongues 31, will take up the manufacturing tolerances of the ampoules 14; their diameter may therefore change Within certain limits without adversely affecting the centering action of the tongues 31. Finally, the package can be slipped into an openended hollow sleeve 16 to enclose the supported ampoules M.
The tongues 31 which in the illustrated embodiment act at no less than eight points on the surface of the ampoule, and bent over and resting against the ampoule walls furthermore have the very desirable efiect, owing to their adhesive friction on the ampoule, of preventing the ampoules from slipping out also when the packing is opened so that the danger of breakage and, in particular, of confusion is substantially reduced.
As the embossed indentations 29 described enable the ampoules to be protected against impacts in their longitudinal direction without requiring tongues to be added on the sides of the unfolded blank, considerable savings in material are obtained in the manufacture of this packing. In addition, folding of the box is simplified since no tongues require folding in and connection. The manufacture of the packing is extremely simple since cutting of the blank and the perforations or apertures 30, prefolding and embossing of the indentations 26 with the ribs 21 can be effected in one operation. Naturally, modifications of the shown box holding five ampoules are possible, the number, size and relative position of the ampoules being capable of change. If the packing is required to meet very stringent demands, the resilient inserted members mentioned above may also be incorporated, if necessary in conjunction with a strip formed of a shock-absorbing material which is attached to the inside of the bottom and top surfaces, such as synthetic foam material or cellulose wadding. It is also possible to provide several inserts, e.g. as shown in FIG. 2, in a common sliding jacket or folded box to form socalled clinical packs containing from to 100 ampoules.
