The present invention relates to a box for razor blades comprising a blotting paper pack so as to enable the blades to be dried after using them. It is an object of the present invention to provide a box holding a package of fresh blades, having a place for used blades, and being provided, in addition, with a drying device.
The box according to this invention has a detachable lid and two intermediate bottoms thus forming three compartments fora pack of loose blotting paper sheets, for used and fresh razor blades respectively.
Preferably all the compartments of the box should be provided with slots so as to enable fresh blades to be taken out or used blades to be put in. In the lower compartment of the box, for instance, in which the blotting paper is to be found, slots are arranged on either long side, the blades to be dried being drawn through them.
A box in accordance with the present invention, for instancey may be made of sheet iron, or all or part of its individual elements may be die cast or pressed from synthetic materials, such as plastics and the like.
The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings,
showing by way of example, a preferred embodiment of the inventive idea.
Fig. 1 is a lateral view,
Fig. 2 is a front view,
Fig. 3 is a longitudinal section in the direction of the line A-B of Figure 2,
Fig. 4 is a cross section in the direction of the line C-D of Figure 1,
Fig. 5 is a front view of a variation,
Figure 6 is a lateral view,
Figure 7 is a top view on the front edge of a lid,
Figure 8 is a longitudinal section in the direction of the line El-F of Figure 5,
Figure 9 is a cross section in the direction of the line G-I-I of Figure l0,
Figure 10 is another variation,
Figure 11 is an intermediate bottom,
Figure l2 is a view of the numbered strip.
A box made for instance from synthetic material consists of a case 5 having a detachable lid t, which is set upon the tapered edge of the case. The case is provided with a lower intermediate bottom 'I which by means of ledges 8 projects into lateral slots 9 on either side of the case. The bottom I0 of the case 5 has an upper curved surface and the intermediate bottom 8 has a lower curved surface thereby defining a passageway having a restricted throat portion. A pack Il consisting of loose blotting paper and put in between said two curved bottoms is under much higher pressure in the middle or throat portion than it is on the sides. Due to this design a blade can, on the one hand, easily be ntroduced, and, on the other, well dried as it is subject to a high pressure in the middle of the case. With a view to improving the drying eifect at the slots 9, the bottom I0 and the intermediate bottom 1 are provided with edges I2 rounded outward; thick blotting paper sheets I4 and I5 respectively are put in between said edges. As a result, the blades to be dried, when being slipped through, will never slide over the bottom or over the ceiling of the compartment, which ensures good drying.
Above the intermediate bottom l, there is inserted another intermediate bottom I6, which is provided with edges I'I, which have angular ledges I8 likewise projecting into the slots 9. In order to fit in these intermediate bottoms, the blotting paper pack is to be put in at first, the two intermediate bottoms 'I and I6 then being forced into the case, which is elastic to such extent that the ledges `8 and I8 respectively may slip into the lateral slots.
The upper side of the intermediate bottom 1, and the intermediate bottom I6 constitute a compartment I9, into which used blades 2| may be introduced from the front side through a slot 20.
The slot 29 is formed by the bevelled ledge of the front wall 22 and the bevelled lower side of the upper intermediate bottom I6, the edge of the front Wall being placed higher than the lower side of the upper intermediate bottom. In this way it is impossible for a blade put in to be pushed out again through the slot.
On the intermediate bottom I6 there are stored fresh blades, which may be taken out either by removing the lid 6 or through a slot 24. The slot 24 should preferably be bordered by the front part of the lid 25 and the upper edge of the intermediate bottom I6.
According to another embodiment of the invention fresh blades are stored within the box in a zigzag package between a parafn paper strip projecting from the slot 24 so as to enable one blade to be taken out by pulling said strip. It is therefore no longer necessary for the individual blades to be packed.
According to the embodiments of the invention as illustrated in Figures 5 to 11, the intermediate bottom I6 is slid, by means of angular and recessed ledges IIa, over corresponding ledges I8a of the intermediate bottom 1; said two bottoms are thereby fastened together. (Fig. 11.) The upper side of the lower intermediate bottom I and the intermediate bottom I6 constitute the compartment I9, into which used blades ZI may be introduced through a slot 20 from the back of thecase 5.
On the intermediate bottom I6, there are stored fresh blades 23, which are laid between a paper strip 26 folded in a zigzag form. The foremost end 2l of the paper strip 26 is led through 3 a slot 28 yprovidedbetween the "front `wall y29 of the case rand .the .frontedge 30 ofthe lid l\',"said edge extending deeply downward. In the front edge 30 of the lid there is a slot 3|, through which the blade lying on the paper strip leaves the box on the front side.
Pulling out the blade is moreover ensured by the part of the paper strip lying behind'the blade which part forms a curve 3'2 GFig. 8') fand'carries forward the blade. By using paraffin paper .only the blade is secured so that it moves forward with the paper strip without its position being changed. Preferably the paper strip, by means of marks (shown in Fig.'12) is pulled out so far only that the curve -32 is approximately in .the middle of the box so as'toensure that the'blade package remains -under velastic pressure.
The lower edge 33 ofthe front lid edge 30 .is
`provided with abevel or aitoothing, thusforming a sharp edge by means of which -the paperstrip may be torn oif at the marks. With a view to enabling .the paper striptobe handledagainfthe foremost lid edge .30 isprovided with:a recess 34,
.and .the upper lid edge with a.recess35,fso .that
the paper strip maybe moved withanger.
When the lid of the case is madeof a .transparent synthetic material .a .sheet of `paper printed with an advertisement or thelike .may be provided on its lower side .above the zigzag package.
On both sides of .thefront of .the icase there are provided short cams 36, which, when .the .lid is put on the case, spring into the lateral .parts of the recess 34. On the other narrowside the lid may then be glued fast to .thecase According to 'Figures 9 andlO, above the bottom I of thecase there is provided .another intermediate bottom `3'l, which'likewisefis clamped in the slots 9 of the case by means of Alateral ledges 38. Anothersmall ydivision 39 is .thereby made into which there may be slid through -the slot 42 a used blade 40 by means of a blotting paper pocket 4I, so that the blademay .be kept without its edges-being injured. The bottom 1.0 is provided with arecess 431to ensure the pocket lll containing the blade 40 being slid out easily.
