Definitions

  • This invention relates to a particular button-fastening arrangement for articles made of semirigid material in general, such as plastics, fuller board, plasticized board and the like, and especially for stationery articles such as fileholders, copyholders or paper-holding cases, folders, briefcases, bags and the like.
  • Button fasteners comprising a male element fitting into a corresponding female element are widely marketed devices
  • the two elements of the button fastener are so disposed that a pull has to be exerted upon the female element in order to release it from the male element upon opening the fastener.
  • a case for holding papers is substantially one of parallel­ epiped shape and has a button fastening means operating on a forward or front wall thereof.
  • the male element of the button is disposed on an intermediate portion of the front wall and the female element on an extension of the upper wall which partially covers said front wall.
  • a first disadvantage is experienced upon closing the case because of the button male element generally being in such a position as to induce bending of the front wall during fastening so that a great pressing force has to be exerted upon the female element, which causes deformation of the case in the long run.
  • a worse difficulty is in any case encountered when opening the container, and is particularly connected with the conventional manner the two button elements are caused to release from one another, that is by a pull exerted upon the female element by means of a grasping flap provided to this end.
  • Said extension partially covering the front wall of the case, besides looking unattractive, is cumbersome and likely to interfere with proper filing of a paper-holding case.
  • the object of this invention is to eliminate all of the above disadvantages by providing a button fastener arranged so that it can be opened and fastened again in an extremely simple manner.
  • the invention is the result of having found, during experiments, that opening of a fastening button is extremely facilitated if the male element of the button is acted upon in a certain manner rather than by applying a pull to the female element of the button.
  • a button fastener has its male and female elements arranged on respective flat overlapping portions of a case, or the like container to be fastened by the button, and the upper portion carrying the button female element has a window provided adjacent to this latter, through which window the flat underlying portion can be acted upon in order to unlock the male element from the female element of the button.
  • opening of the button is obtained by exerting a slight pressing force upon a region close to the male element to produce a lever effect that induces a swinging or oscillation of this male element thereby causing it to instantaneously disengage from the female element.
  • This arrangement makes it possible to eliminate all of the disadvantages connected with opening systems of a known technique utilizing a grasping flap whereby a pull can be exerted upon the female element of a button. At the same time, opening of the button is extremely easier to do by the arrangement according to the invention.
  • the button fastener is conveniently arranged on an upper wall thereof,
  • the male element of the button is preferably arranged on an inwardly folded portion of a front wall of the container, adjacent to its folding edge, so that also refastening of the button is simplified with no bending being induced in the material of the region where the male element is provided.
  • a case for holding papers is comprised of a bottom or lower rectangular wall 2 and an upper or cover wall 3 of the same size as the bottom wall 2 to which it is connected through a back wall 4.
  • the bottom wall 2 also has two sidewalls 5 and a front wall 6 which extend upwardly therefrom and which have the same height as the back wall 4 so that the case will take the shape of a parallelepiped when in closed condit­ion.
  • the sidewalls 5 and front wall 6 have extensions 7 and 8 respectively, which are folded inwardly of the case parallel to the bottom wall 2. In particular, first the extensions 7 on the sidewalls 5 are folded up and then the extension 8 on the front wall 6 is folded over them.
  • the in-turned portion 8 is secured to the in-turned portions 7, for example, by means of buttons 9, in order to have the walls 5 and 6 kept in raised position when the case 1 is in open condition.
  • Closing of the case 1 is ensured, as is the case with conventional containers of this type, by means of a button.
  • the characterizing features of this invention reside in the manner by which the button is acted upon for causing it to open, and the location where the button is arranged.
  • the male element of the button is arranged on the in-turned portion 8 of the case front wall 6 adjacent to the folding line 12 corresponding to the front edge of the closed case, while the female element 11 of the button is carried by the upper wall 3 in such a position as to be superposed to the male element 10 upon closing the case 1.
  • a window 13 for example of circular shape , through which window the underlying region of the folded portion 8 carrying the male element 10 can be acted upon to cause this male element to release from the associated female element 11 upon opening the case.
  • opening of the case is effected by exerting a slight pressing force, for example by a finger, upon the folded portion 8 through the window 13.
  • the female element 11 has an inner circular recess 15 in which two oppositely arranged springs 16 are apparent in a manner known per se .
  • the male element 10 is in the form of a conical pawl 17 whose diameter is decreasing in a direction towards the base of the pawl so that upon closing the button the pawl will first cause the springs 16 to move away from one another and then to snap back against the tapering wall of pawl 17 to keep it clamped in place.
  • button fastening of the invention is not restricted to the particular container described herein before, but may be extended to any article, such as fileholders, folders, briefcases, bags, etc.., utilizing this type of fastening means.
