Description

United States Patent 3,270,874 POLYSTYRENE MULTI-CLOSURE STRIP SCORED FOR SEPARATION INTO INDIVIDUAL CLO- SURES Frank E. Hilton, Milwaukie, Oreg., assignor, by mesne assignments, to Kwik Lok Corp., Yakima, Wash., a corporation of Washington Filed Aug. 27, 1965, Ser. No. 483,122 2 Claims. (Cl. 206-56) This invention relates to closures formed of fiat material such as extruded polystyrene and, more particularly, to a multi-closure strip of such material wherein the strip is scored to permit ready detachment of individual closures.
Sheet polystyrene closures are used to close the necks of polyethylene bags in which food and other products are packaged. Such closures are made in strip form, the strips being adapted for separation into individual closures. The individual closures are characterized by having a bag-neck-con-fining mouth, which is connected to one of the edges of the closure by a narrow open-ing having widely flaring lips.
A problem has existed in rendering the strips separable into individual closures. The strips are formed in a diecutting operation, and they must fit into the various machines that have been developed to apply them to bags. Individual closures must thus be readily separable from the strip, and they must separate without leaving any sharp protrusions which might scratch the hands of a person removing the closure from a bag. It is also desirable that the individual closure have a cleanly formed appearance when separated from the strip, thereby to be a merchandising asset.
-A solution to the problem was disclosed in Paxton Patent No. 3,164,250, which joined adjacent individual closures by a pair of perpendicular webs, the length of each of the webs being substantially greater than its width. Separation of individual closures from the strip was efiected by in-plane forces applied perpendicular to the edges of the strip, thereby to shear the individual closures through the webs. This attempted solution, however, results in leaving a part or all of the webs attached to one or the other of the adjacent individual closures, and does not effect a complete detachment of both webs at both their ends. Such, of course, results in a ragged edge appearance to the individual closures, and leaves protrusions thereon which can scratch a persons hands.
It is thus as object of the present invention to provide a multi-closure strip of the type above described with an improved means for separating individual closures therefrom.
It is a further object of the present invention to provide such a multi-closure strip with means whereby the individual closures may be completely separated from the strip, leaving no protrusions on their sides to scratch the hands of a person using them.
It is a still further object of the present invention to provide such a mu lti-closure strip wherein the individual closures may be completely separated firom the strip by bending the same along axes transverse to the strip, which axes also define the sides of adjacent individual closures.
It is a still further object of the present invention to provide such .a multi-closure strip wherein more individual closures may be formed within the same length of strip, thereby to reduce wastage of material.
These and other objects are accomplished by scoring both surfaces of the multi-closure strip along axes transverse to the strip, which axes define the sides of adjacent individual closures, thereby to permit the individual closures to be separated from the strip by bending the strip 3,270,874 Patented Sept. 6, 1966 along the scored lines. Other objects and advantages will be made manifest in the following description, when taken in connection with the accompanying drawings, in which FIG. 1 is a perspective view of a preferred embodiment of the multi-closure strip of the present invention:
'FIG. 2 is an enlarged plan View of a portion of the strip showing in greater detail one of the individual closures in the multi-closure strip of the present invention:
FIG. 3 is an end elevational view of the strip portion shown in FIG. 2; and
FIG. 4 is an end elevational View of an individual closure after it has been completely separated from the strip.
Referring to the drawings, the preferred embodiment of the present invention comprises a multi-closure strip 10, which is preferably formed from a thin, fiat, stiff strip of polystyrene or like material, which is conventionally .035 inch in thickness and inch in width. The strip 10 is die formed to produce in the strip a series of individual closures 11. Each individual closure 11 has a bag-neck-confining mouth 12, which is connected to one of the edges '13 of the strip 11 by a narrow opening 14 which widens into lips 15. The neck of a polyethylene bag can be twisted and inserted past the lips .15 and through the opening 14 into the mouth 12 in the usual manner.
The strip -10 is formed with notches 20 in each edge 13 and notches 21 in the opposite edge 22. Notches 20 and 21 are arranged symmetrically relative to transverse axes 23, which axes are equally spaced from and parallel to the transverse axes 24 of the bag-neck-con-fining mouths 12 and openings 14. The transverse axes 23 define the sides 25 of adjacent individual closures 11, as clearly shown in FIGS. 2 and 4. The individual closures 11 thus are in side-by-side relation in the strip 10.
The polystyrene from which the multi-closure strip 10 is made is a stilt, thin sheet material which gives the individual closures 1 1 both stifiness and flexibility, thereby adapting them to being applied and removed from a bag many times without injury. The polystyrene material is also readily adapted to being scored and when so scored, is readily frangible along a scored line.
To permit the individual closures 11 to be separated from the multi-elosure strip 10, the strip is scored on opposite surfaces 30 and 31 along lines 3-2, each of which coincides with a transverse axis 23, as clearly shown in FIGS. 2 and 3. Such scoring can be practically effectuated during the die-cutting operation which forms the rest of the openings and notches. When so scored, an individual closure 11 can be completely broken away from the strip .10 merely by bending the closure along the transverse axis 23, the polystyrene material readily breaking under one or two flexures. Scoring the polystyrene to a depth of between .008 and .010 inch in each side has been found satisfactory in .035 material.
The sides 25 of the separated individual closures '11 have a clean looking appearance and there are no protrusions that can scratch a persons hands or otherwise give the individual closure a ragged appearance. The individual closures may also be readily dispensed from machines that apply them to the bags. Use of scoring to form the sides 25 of the individual closures instead of elongated webs also results in a 5 percent saving in mate rial, since more of the individual closures can be formed in a given length of polystyrene strip than was possible heretofore.
While one particular embodiment of the invention has been described, it is to be understood that the specific details shown are merely illustrative and that the invention may be carried out in other ways without departing from the true spirit and scope of the appended claims.
I claim:
1. In a multi-closure strip, wherein the closures has a bag-neck-confining mouth and a narrow opening located in a longitudinal side edge thereof and communicating with said mouth for admitting a bag-neck therein, said mouth-s and openings being symmetrical with respect to first transverse axes across said strip,

thereby to permit individual closures to be separated from said strip by bending said strip along said second transverse axes.
2. In a multi-closure strip, wherein the closures each has a bag-neck-confining mouth and a narrow opening located in a longitudinal side edge thereof and communieating with said mouth for admitting a bag-neck therein, said mouths and openings being symmetrical with respect to first transverse axes across said strip,
