Filed Feb. 4, 1957, Ser. No. 638,043 1 Claim. (Cl. 154--53.5)

The present invention relates to a pressure-sensitive adhesive tape handle construction, and it particularly relates to a pressure-sensitive adhesive tape handle construction which may be utilized for carrying packages or other tying or binding purposes in connection with the carrying of packages or the provision of handles for various types of enclosures, boxes, packages and the like.

' It is among the objects of the present invention to provide a simple, laminated tape construction which may be readily manufactured on a large scale by available coating and heating machinery and which may be'readily utilizedfor attachment to containers, packages, wrappers and the like to provide a convenient handle, by means of which such packages may be both sealed and carried.

' Another object is to provide a convenient, readily applied, laminated handle construction for boxes, containers or other enclosures which will occupy small space in merchandising, shipping and storage, and yet may be readily applied to such package, box or other container as a handle as well as a sealing member.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

, In accomplishing the above objects it has been found most satisfactory to provide a laminated tape construction which will have a re-enforced, strengthened base portion and a removable cover portion, part of all of which may be removed, depending upon whether the tape is to be used as a handle or a binding.

The base sturucture consists of a filament tape having a sheet material base of paper, synthetic sheet plastic material, cellophane, or even woven or matted fabric, which in the preferred form desirably carries a plurality of closely placed parallel rayon, nylon, glass or other fibers running continuously through the entire length of the tape, desirably in filament form rather than in spun form.

These filaments, which extend through the tape longitudinally of the major axis thereof and which are positioned closely spaced together or in side by side relationship, are desirably imbedded in an elastic, pressure-sensitive adhesive and are laminated to the base sheet which may be in the preferred form a smooth cellophane or regenerated cellulose or cellulose acetate backing.

Such a base laminated filament re-enforced backing tape, with a pressure-sensitive adhesive facing, has great shock and tear resistance and may be used both for packaging and carrying relatively heavy containers or articles.

It cannot be readily ripped and must be cut, and when applied to a package or to a paper surface of a carton or wrapper will set permanently and become substantially an integral part of the package itself, while re-enforcing the portions of the package to which it is attached.

In the preferred form of the invention, the pressure sensitive adhesive is coated with a sheet of material which may be readily removed in part or whole without difficulty from the pressure-sensitive adhesive facing.

Although the cover for the pressure-sensitive adhesive coating may widely vary, it has been found that a craft or crepe paper with the grain extending transversely to the longitudinal axis of the material is most satisfactory.

In the preferred form, a series of scoring or cut lines are provided in the crepe or other removable facing so that portions of such facing may be removed by themselves to enable the pressure-sensitive adhesive to be applied in the form of a handle to a carton or package with the uncovered, pressure-sensitive adhesive face portions being directly attached to the carton or paper wrapper and the unremoved facing serving as a contact against the hand for handle carrying purposes.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claim hereunto appended.

In the drawings wherein like reference characters de note corresponding parts throughout the several views:

FIG. 1 is a top perspective view of a package with the handle construction of the present invention applied thereto.

FIG. 2 is a perspective view of the handle construction with the end covering portions in position but split so that they may be readily removed from the balance of the liner.

FIG. 3 is a top perspective view of the handle construction with the end score portions removed and the pressure-sensitive facing exposed with the intermediate portion of the covering strip being still in position to serve to contact the hand when used as a handle.

FIG. 4 is a transverse vertical sectional view upon an enlarged scale upon the line 44 of FIG. 3.

FIG. 5 is a plan view with one of the end portions partly torn away, indicating how a plurality of handle units may be held as a single strip construction.

FIG. 6 is a top plan view showing a strip with a plurality of tear or score lines enabling portions of the cover ing material to be removed at will to give various lengths of handles to match various package sizes.

FIG. 7 is a top perspective view showing a double grip tape construction with a tear line, said construction being suitable for double application at each end to a relatively thinarticle to be carried.

FIG. 8 is an illustration of FIG. 7, showing the means of separating the pressure-sensitiveadhesive portions so that they may be attached on an element to be carried or lifted.

FIG. 9 is a side perspective view indicating the application of FIGS. 7 and 8 to a relatively thin package construction.

In FIG. 1 there is shown a package or carton A, a binding or sealing strip B and a handle construction C having the connected ends D and the lifting or handle portion E. Y

The strip before application is illustrated in FIGS. 2, 3 and 4. The strip as shown in FIGS. 2, 3 and 4 consists of a sheet plastic or sheet fabric material 10 having a pressure-sensitive adhesive surfacing 11 which carries a plurality of closely spaced parallel re-enforcing threads or filaments or rayon, nylon or glass fiber or other filament materials.

These parallel re-inforcing threads or filaments may be included in the body of the base fabric material 10 as indicated at 12 in FIG. 4 or they may be placed in the adhesive material or facing 11 or both.

Covering the adhesive facing 11 is a paper or other covering material 13 which desirably has a grain as indicated at 14 extending transversely to the grain or direction of the filaments or fibers 12.

Normally, the sheet plastic 10, whether it be regenerated cellulose or cellulose acetate, is coated with the adhesive 11 and the filaments 12 are imbedded therein. Then the crepe paper or other removable paper facing 13 is applied thereto and it may be scored or slit as indicated at 15. The prepared handle, as shown in FIG. 2, then is ready for attachment to a package, as indicated at A, by removing the covering end portions 16 to convert it into the form as shown in FIG. 3.

In FIG. is shown a series of strips, such as indicated at FIG. 2, which are mounted in a block or group as indicated at 17, and which may be ripped apart along the tear lines 18.

Each of these strips are provided with the transverse cut lines or perforation lines so that the end covering portions 20 may be removed to give a series of strips, such as indicated inFIGS. 2 and 3.

In the structure shown in FIG. 6 the strip is provided with varyingspace perforations 21, 22 and 23 which permit the various lengths of exposed pressure-sens} tive adhesive material to be provided to match different sizes of packages or containers and to I give varying lengths of handles.

In the embodiment shown in FIG. 7 there is a double grip type of device with two laminated structures 24 which have outer smooth faces 25 and inside pressuresensitive faces 26 which are separated by a central cover strip 27.

When the two faces 26 are removed from the central facing cover strip 27 which may be ripped off at the tear line 28, there will be formed a double attachment such as indicated at FIG. 9 which permits both sides 30 or the end 31 of the handle member 32 to be attached to opposite sides 33 of a thin package or object 34 to be carried.

In the embodiment of FIGS. 7 and 8 which is applied as indicated in FIG. 9 there are two strips which have inside pressure sensitive adhesive faces 26 when the cenfor cover strip 27 is removed. The center cover strip 27 which separates the pressure-adhesive faces after being ripped off of the tear line 28 permits the faces to be applied to opposite sides 33 to a package or object 34.

The outer face 25 is left in position in the handle portion 39 to give extra strength to the handle. Both the outer layer 25 as well as the center portion 27 are removed when the handle is applied in FIG. 9. The cover 25 may terminate at the side edges although in FIG. 7, it is shown as being turned inwardly to form the facing cover strip 27.

In the embodiment in FIG. 7 the strip 25 covers both sides of the strip 26. The laminated structure 24 which has the top face 25 is repeated at both top and bottom in the laminated structure of FIGS. 7 and 8 with the numeral 24 indicating the entire structure and the face of the structure being indicated by the numeral 25.

' It is thus apparent that the. applicant has provided a simple, reliable, convenient handle and binding construction.

The same strips, if desired, may have the paper facing 13 altogether removed and the entire length of the strip may be used for re-enforcing, bundling or holding purposes. However, the principal advantage resides in holding a central section, such as indicated at 13 in FIGS.

4 2 and 3, in position so that the strip may serve as a handle, as indicated in FIG. 1.

However, the base element carrying the pressure-sensitive adhesive coating or the covering face may be made of sheet plastic materials or woven or matted fabrics or paper materials, whether smooth or crepe. The important feature is to provide cuts at the ends of the strips so as to allow the liner from both ends to be picked off the tape which is not cut, exposing a live adhesive at both ends.

These sections are attached to both ends of a carton and the center portion which does not have the liner removed still has the backing in position and carries the facing part of the handle.

The handles may be of various sizes and widths, and, if desired, a plurality of handles may be used in combination.

As many changes could be made in the above pressuresensitive adhesive tape handle construction, and many widely different embodiments of this invention could be made without departure from the scope of the claim, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.

Having now particularly described and ascertained the nature of the invention, and in what manner the same is to be performed, what is claimed is:

In a paper wrapped package, a three ply pressure-sensitive-adhesive attached trilaminate handle structure comprising a trilaminate tape having a central handle portion and end pressure-sensitive-adhesive portions, the entire length of the tape having an elongated base strip carrying on its inside face a pressure-sensitive-adhesive and also integrally carrying a plurality of closely spaced parallel longitudinally extending filaments and having an inside crepe paper under-cover for said pressure-sensitive-adhesive with a grain transverse to said filaments, the portions of said under-cover in the end portions being removable to enable said end portions to be attached to a paper wrapped package and the portions of said under-cover in the handle portion serving to contact the hand when the handle portion is utilized to carry a package, said base strip being cellulose acetate and having embedded in the body thereof said parallel filaments.
