Specification of Letters Patent.
To all whom it may concern Be it known that 1, PETER A. HorrMAN, a citizen of the United States, and a resident of Hastings, in the county" of Dakota and State of Minnesota, have invented a new and Improved Envelop, of which the following is a full, clear, and exact description. 1
This invention relates to improvements in envelops, and has for an object to provide an improved structure which will act properly as a closure or document wrapper while eliminating tapes, rubbers and other similar fastening means.
Another object of the invention is to provide an envelop which may be bodily opened and folded whenever desired and secured in a folded position by a suitable clip which does not project beyond the surface of the envelop.
-In' carrying out the object of the invention a body is provided formed with side and end members adapted to be folded over on the body andsecured in a folded position by suitable clips or slidin catches arranged upon one of the si e members.
I These sliding clips or catches are arranged in a fold of one of the side members and formed with a turned-over portion designed the invention shown in an open position;
Fig. 2 is a perspective View of the structure shown in Fig. '1, but in a closed position;
Fig. 3 is a section through Fig. 1 on line 3-3, part of the envelop being shown in its folded position by dotted lines; Fig. 4: is a detailed perspective view of one of the slidin%clips.
eferring to the accompanying drawing by numeral 1' indicates a body which acts as the back of the envelop. Extending from the body 1 are side members 2 and 3, and also end members 4 and 5, members 2, 3,4 I
and 5 being preferably formed integral with body 1. The end members 4 and 5 are provided with scored or pressed portions 6 and i 7 which in effect cause a corrugation of the end members, the scored or pressed portlons Patented Jan. 11a, rare.
Application filled April 9, 19149 serial 830,700... y
being arranged adjacent body 1 as clearly shown in Fig. 1. I It is not to be understood that'the scoring is for the purpose of tear.- ing the end members, but merely for the so purpose of allowing the end members to be bent, as shown in Fig. 2, for properly fitting over an inclosure. In making these scored lines or pressed portions the material is merely compressed, and is not removed, 5 whereby the end members retain their original strength but may be easily folded at any desired point for accommodating an inclosure of substantially any thickness. The sides 2 and 3 are also provided with pressed portions 8 and 9 which, however, do not extend to the edges of the side portions as in the case of the pressed portions 6 and 7. It
- will be evident that the pressed portions. 8
and 9 could, if desired, extend for the full width of the side members 2 and 3. The extremeouter portion of side member 2 is folded over for forming a flap 10, while the extreme end of side member 3 is provided with a turned-over portion defining a flap so 11, which flap is preferably secured to the body of side member 3 along line 12 by any desired means, as a suitable adhesive. Arranged to slidingly fit within the loop formed by the turned-over portion 11 are 35 sliding clips 13 and 14. These clips as more clearly shown in Figs. 3 and 1 are formed with a body 15 having a slot 16, and with a. turnedover portion 17 arranged with a curved end 18. The turned-over 9o portion 17 is designed to beresilient so as to normally press a ainst the side 2 when the envelop is folde to the position shown in Fig. 2. In order that the members 13 and 1 1 may be properly held in place eyeas lets 19 are provided which will not only hold in place the members 13 and 14: but guide the same in their reciprocatory movement. In order that these members may be properly removed or disconnected from we side 2 a pressed-out or raised portion 20 is formed in each of the members 13 and 14. By this structure the clips may be engaged by the thumb and forced outwardly as shown in Fig. 1, whereby the side 2 may be 1&5 unfolded.
By constructingithe envelop as described with the various pressed portions 6, 7, 8 and 9, various sized articles ma be; placed in the envelop and the same properly folded and locked'=in-' a folded position by the clips 13 and 14. Theenvelop in fact not only acts as an envelop, but as a document holder or file, and automatically ad usts itself to the contents whether the same has been 1ncreased or decreased. It will also be noted that the clips 13 and ll are provided with notched-out portions 21 at the edges, Whereby the clips may be easily moved When it is not desired to use the pressed-out or raised portions 20.
What I claim is- In an envelop of the class described, a substantially rectangular body, foldable side and end members connected with said body, said foldable side and end members being rectangular whereby when the same are folded there will be no openings at the cor- 11ers, each of said side and end members being provided with crimped or corrugated portions so as to allow a bending action of said members substantially at any point, one of said side members loeinn' m-nviflml hers being provided with a folded-over end having the edge secured in place, a pair of eyelets on each side extending through said last mentioned folded-over portion, and a sliding locking clip for each pair of eyelets, said clips having bodies extendin into said folded-over portion, said bodles being flaps for moving the same to an outer position.
In testimony whereof I have signed my two subscribing witnesses.
PETER ALBERT HOFFMAN.
