  • a proposed shaving system employs a razor blade permanently secured to a body of plastic material with coupling structure formed in the body to enable the blade unit to be connected to a cooperating razor handle for use in shaving. Examples of such blade units are disclosed in copending US. Pat. application Ser. Nos. 124,069 now abandoned and 124,068, now Pat. No. 3,724,070. Such blade units are particularly suited for use in conjunction with a razor handle of the type disclosed in 11.8. Pat. application Ser. No.
  • Another object of the invention is to provide a novel and improved package for razor blade units which provides a convenient repository for used blade units and is adapted to receive a used blade unit from a razor handle without the necessity of the user touching the used blade unit.

  • Each chamber further includes structure for releasably retaining a blade unit therein and one wall of each chamber functions as a barrier which obstructs movement of the blade unit in a transverse direction while permitting movement of a handle coupling structure into and out of the chamber in that transverse direction for engagement and/or disengagement with coupling structure of the blade unit.
  • the blade unit securing structure includes two latch members, that are disposed at opposite ends of the chamber, each of which has upper and lower camming surfaces, one latch member being mounted on the barrier member and being in the form of a pedestal member so that the latch members may flex to permit insertion and removal of the blade unit from the chamber and the other latch member projecting from an end wall.
  • the securing structure includes two similar latch members that are disposed on the side walls of the chamber and engage a bottom surface of the coupling structure.

  • the transverse dimension of the chamber is coordinated with and less than the corresponding (Width) dimension of the blade unit so that the blade unit is in firm frictional engagement with internal surfaces of the chamber and the blade unit offset surface is urged beneath the latch surface so that the blade unit is retained in the chamber.
  • Support structure in the chamber positions the blade unit so that the plane of the blade unit coupling structure is disposed parallel to the base of the package while the blade elements are disposed at an angle to the base of the package.

  • the configuration of the barrier structure is coordinated with the position of a blade unit coupling structure in the chamber so that the cooperating coupling .structure of that handle unit may enter freely into the chamber while the barrier member impedes the transverse movement of the blade unit in the chamber, thus facilitating the coupling of the handle member to the blade unit.
  • two series of chambers are disposed in aligned relationship end to end with a common barrier member disposed between each two corresponding chambers.
  • one series of chambers may receive used blade units while the other series of chambers stores new blade units.

  • each said chamber includes two parallel spaced walls that define a transverse dimension that is coordinated with the corresponding width dimension of said blade unit, each said securing surface is integral with one of said partition walls so that said blade unit in said chamber is in firm frictional engagement with said opposed cooperating surfaces of said chamber, each said securing surface is adapted to define a fulcrum point and the chamber surface opposite said securing surface is adapted to engage a blade unit surface which is cammed along said opposite chamber surface as the blade unit is rotated about said fulcrum point, and further including support structure above said base for positioning a blade unit so that said blade unit coupling structure is disposed adjacent said opening, said support structure being adapted to position said blade unit in said chamber so that the top surface of said blade unit is inclined with respect to the base of said package and the portion of said top surface spaced furthest from the base of said package is adjacent said fulcrum point.
  • first and second chambers are in endwise alignment and are separated by said partition wall, and said partition wall permits sliding movement of said handle from said first chamber to said second chamber.
  • each said razor blade unit including a body and at least one blade element permanently secured to said body, said body including slidably engageable coupling structure extending transversely of said body for connection to a handle,
  • the said package including a base, a plurality of spaced partition members upstanding from said base, said partition members being disposed to define a series of open top blade unit receiving compartments disposed in a row,
  • said blade unit retaining structure including an inwardly projecting securing surface that overlies a surface of a blade unit disposed in said compartment and cooperating with a compartment surface in opposed relation to said projecting surface to receive a blade unit therebetween and secure said blade unit in firm frictional engagement in said compartment,
  • each said compartment enabling a blade unit to be introduced into said compartment by inward movement through said open top towards said package base and secured in said compartment by engagement by said blade unit retaining structure and to be removed from said compartment through said open top by outward movement away from said package base, said outward movement overcoming the securing force of said blade unit retaining structure and releasing the blade unit,
  • each said compartment having an opening through which a handle may be introduced in a transverse direction to slidably engage the coupling structure of said blade unit within said compartment, said blade unit being removable from said compartment by movement of the handle with the attached blade unit away from said package base.
  • a package of razor blade units comprising a series of generally rectangular open top chambers, each said chamber having side wall surfaces and end wall surfaces; a series of razor blade units disposed in said series of chambers, each said razor blade unit including a body, and at least one blade element held by said body, said body including slidably engageable coupling structure extending transversely of said body; structure within each said chamber for releasably retaining a razor blade unit therein; the open top of said chamber enabling a razor blade unit to be introduced into said chamber by inward movement through said open top and secured in said chamber by engagement by said retaining structure and to be removed from said chamber through said open top by outward movement, said outward movement overcoming the securing force of said razor blade unit retaining structure and releasing said razor blade unit, the side wall surfaces and end wall surfaces of each said chamber preventing introduction of said razor blade unit into or removal of said razor blade unit from said chamber in either lateral or transverse directions, and each said chamber having an opening in one of said end wall surfaces through which a handle may be
