TOBACCO MOISTENING DEVICE Filed July 6, 1928 I ma 4 Patented Jan. 19, 1932 PATENT OFFICE nan entmwann. or nnnnm-wimrnnsnonr, onamm TOBACCO MOISTENING: DEVICE Application filed July 6, 1928, Serial 1T0.

Tobacco moistening devices are known, m which a layer capable of retaining moisture is wrapped up in a material which is impervious to moisture. The known constructional forms have the disadvantage that the water of the moisture retaining layer easily comes in contact with the tobacco or the cigarettes, so that the cigarettes become damaged.

According to the present invention the 1 layer which is impervious to moisture projects so far beyond the moisture retaining layer at all those edges or cross-sectional areas, at which it can give ofi moisture, that the moisture given off cannot be transmitted directly to the tobacco but only to the air of the container in which the tobacco is stored. In order that a considerable amount of moisture shall be given off, perforations may be provided in the tobacco moistening device, the edges of the material which is impervious to moisture being slightly turned up so as to cover the moisture retaining layer to a certain degree. A metal foil may suitably be used as the material which is impervious to moisture. In place of metal foils, materials sprayed with metal or any other non-porous flexible substances may be used as the impervious material.

Various constructional examples of the present invention are shown in the accompanying drawings, in which,

Fig. 1 represents an insertion, in which the moisture is given off only at the edges of the moisture retaining layer,

Fig. 2 a section on line IIII of Fig. 1,

Fig. 3 a view of an insertion which is pgrforated on one side and opened at one e ge Fig. 4: a section on line IV-IV of Fig. 3,

Fig. 5 an insertion perforated on both sides Fig. 6 a section on line VI-VI of Fig. 5,

F i 7 a section through another constructiona form.

The insertion consists of a moisture retaining layer 1 of moistened blotting or absorbent paper and a sheath 2 of metal 011 or the hke which is impervious to water. The layer 1 is wrapped up in the sheath 2 so that the insertion is in contact with the 290,774, and in Germany mike, 192s.

outer air either only at the lateral edges, as shown in Figs. 1 and 2, or additionally as regards the superficial areas of the perforations 3, which may be of any shape, as shown in Figs. 3-7. The given off moisture must not directly reach the contents of the container into which the insertion is placed after'the blotting paper has been moistened, but may only be imparted to the air in the container, 'for instance cigarette box. For this purpose the sheath 2 has an edge 4 projecting beyond the sheet of blotting paper. When the insertion is laid on the top of the cigarettes contained in the box, only that side which is the lower one when it is being inserted need so project, as is assumed in Figs. 1-6. If, however, the insertion is to be laid between difierent layers of cigarettes, the upper covering sheet 2 must also be widened so that in this case as well an edge 5 will be produced (Fig. 7).

According to Figs. 1 and 2 moisture is only given off through the lateral edges of the blotting paper, therefore relatively slowly. When it is desired that the water shall be imparted more rapidly to the air the covering layer and the blotting paper is perforated, either as shown in Figs. 3 and 4, only the lower covering layer and the blotting paper being perforated, orlso that the holes extend right through as in Figs. 5-7. In both cases provision must be made that no moisture can reach the cigarettes at the perforated areas. For effecting this, whenthe perforations are being made, the material of the covering layer is bent up to form a rim 7 which partially covers the edges of the perforations in the blotting paper and thus prevents drops of liquid trickling out directly on to the cigarettes. When the perforati ons are made by stamping, these edges will as a rule be bent up in any case. It is then only necessary to provide that the perforations are stamped out from the side on which is the broader covering layer, the edges of which project beyond the blotting paper, and the insertions must of course be placed in a corresponding manner into the cigarette box.

If the insertion is to be plac'edbetween the ci arettes, it is necessagy after the holes have en punched to ben in the edges of the perforations on the upper covering plate in a separate 0 ration, so that turned in ed 8 are pro uced (see Fi 7).

Ir i the constructional examp es shown, only the two longitudinal edges of the sheet of blotting paper are exposed for giving off moisture to the air, the two transverse edges being covered by the metal foil being bent over. If the blotting paper be fixed 1n the insertion in a different manner, the other edges might also remain open. Thus, for instance, 1n order that all the edges of the moisture retaining layer shall be open, metal foils might be stuck on the blotting paper by means of a waterproofing adhesive, in which case a further insulating layer formed by the adhesive would be produced, which would prevent the metal corroding. In this case it would of course also be necessa for the covering layer to project beyon the sheet of blotting paper at the side of the insertion which is to rest against the cigarettes or atboth sides.

The invention is more particularly intended for insertion in cigarette boxes, but may of course, be used when storing other tobacco manufactures. It may also be used for insertion in cigarette cases in which case it is only necessary to provide suitable devices, for instance sprin clamps, for holding the insertion firmly in axe cover of the case.

The insertion is always placed in the box or case in question, after the sheet of blotting pa er has been moistened.
