WRAPPER.

l Specification of Letters Patent.

Patented June 14, 1921.

Application led September 18, 1916. Serial No. 120,663.

. To all whom z'tma-g/ concern.'

Beit known that I, F BERT OLDHAM, a citizen of the United States, residing at Auburn, county of Androscoggin, State of Maine, have invented certain new and useful Improvements in Wrappersa of which the following is a specification. This invention relates to a novel pack and particularly to a wrapping tube of such construction and designl as to facilitate the wrapping of a body such for instance as a sardine can.`

Many types of articles are now marketed either in paper envelops or glass containers or card board containers or in cans and frequently the latter are provided with ornate finishers to enhance the appearance of the stock and carry out particular characteristics of marks or labels and these articles are commonly disposed of from stock wrapped in a light paper sheathing or wrapper, and at the present time the purchasing public has been educated to expect that many articles are thus commonly marketed. The wrapper is frequently applied to the vessel or container by a wrapping process in which a piece of paper is vfolded around the article or container and the projecting end portions of the wrapper are then again folded over the ends of the package in such a manner as to form a neat article and at once serve to protect the finish or surface of the wrapped article from being'soiled by being handled or injured, and also is protected against corrosion or rust.

According to the present manufacturing or marketing methods the wrapping of the body or container such as for instance a sardine can, when this work is done by hand is under present conditions practically prohibitive in this country. though it is a common practice in foreign countries and the goods shipped into the United States so wrapped. Y

It is one of the objects of the present invention to provide a pack in which the article or body to be protected is eiciently covered by a wrapper in the form of a tube which is of greater length than the article contained and is of approximately the same cross-sectional area, and has for its further object to provide for an economical and eiiicient wrapping of the article or body or container to be wrapped and to produce a pack which will be attractive in appearance and substantial.

It is therefore a feature of my invention to provide a wrapping tube which preferably is attened longitudinally and has its longitudinal edges tucked inwardly through out its length, forming a shallow infold and which when an article to Vbe wrapped such as a sardine can is inserted in the end ofthe tube, the side faces or panels of the latter readily spread or open and after the can has been positioned intermediately between the ends of the tube the partly opened overhanging portions of the tube have substantially V-shaped inwardly directed side grooves which are automatically produced by the semi-opened condition of the marginal tucks of the wrapper. These tucked edges are adapted to clearly facilitate the operation of preparing the overhanging portions of the tube at each end of the can to be exactly folded in opposed or overlapping relation upon one another and then over the end of the can.

The invention therefore consists of a pack consisting of a container preferably of rectangular cross section, and a wrapping tube for the container or can which is of greater length than the can `and of approximately equal cross-sectional area, the tube being provided with vlongitudinal inwardly tucked portions which are folded in pairs toward each other across each end of the container or can and forming tongues or tangs which are folded one upon the other and then laid lover the end of the can, the folded tongues or tangs being sealed in folded position by a label or other suitable sealing expedient.

A preferred form of the invention and a method of wrapping the tube about the container is described in the following specification and illustrated in the accompanying drawing herein.

Figure l is a perspective view of a wrapper being adjusted upon a can and showing the partly expanded end of the tube in placing the can, while the opposite end of the tube is being slightly opened and showing the inwardly directed longitudinal tucks.

Fig. 2 is a perspective view showing a further step in the method of folding the wrapping to be placed about the .inclosed container which is illustrated in dotted lines.

Fig. 3 is an end view of the wrapping Vtube with its end tongues or tangs folded perpendicularly to the end of the container in the second step of the folding operation.

Fig. it is a perspective view of the wrapping tube as substantially finally folded down upon the inclosed can and showing the application of a sealing label.

In practising my invention, I prefer to employ arwrapper in the form of a piece of pliable material of tubular form illustrated` at 2 Fig. 1, the tube preferably being of a durable, attractive, oiled paper and of a length considerably greater than the length of the can 3 which is to be wrapped. The wrapper 2 is in the form of a attened tube having its longitudinal sides .folded inwardly to form inwardly directed tucks or folds et, the side forming portions 5 of which are ap proximately of a width of about one-half .the thickness of the canY 3 so that when the latter is inserted as in Fig. l into one end of the tube, t'he fold 4; expands and forms a side portion 6 about equal in thickness to the thickness of the can. After `the latter has `been positioned intermediately between the ends of the top and bottom of the tube 2 the overhanging ends as shown in Fig. 2 may then be folded together and then upwardly over the ends of the container as shown in F ig. 3.

lOne of the importa-nt features of the present invention is the provision of the inwardly directed tucks 4L which serve when the wrapping tube has been adjusted upon the can 8 in its proper position to automati cally form 4\l.shaped panels or grooves between flaring sides 5 which act as guides for the fingers of the operator to facilitate the inwardly folding` action of the side portions 5 as shown in F ig. 2,V to form uppe1 and lower substantially triangular tongues 7-7 above and below the intu'rnedends 6 of the sides 5. After 'the overhanging end portions of the tube have been folded to ythe positions indicated in Fig. 2 and the ends 6 brought into overlapping position across the end of the can, the upper and lower tongues or tangs- .7 7 may then readily be folded upwardly with neat straight edges sharply angular to each otheras shown in Fig. 3 with a position perpendicular to the length of the tube on the tangs, then folded over the corner of the can as shown in Fig. elin superposed relation at caf-h end of the can where they may be readily and neatly sealed down by the application of a label 9 of any Vsuitable form and proportion, one type of which is illustrated in Fig. Il.

From 'the foregoing it will be seen that I have provided a pack which is extremely neat in appearance, is substantially air tight and practically water proof so far as the purpose in `hand makes it necessary and the can is well protected and when the tube is of a material which is translucent the decoration on the can or its color may be disintermediate eerned through the wrapper and chiefly it will be observed that 1 have provided a wrapper which being prepared in large quantities in the form of a complete tube and subdivided into sections of the requisite length determined by the size of the can, may be furnished economically, and maybe applied either manually or mechanically to the can to be covered and linally sealed.

lWhat 1 therefore claim and desire to secure by Letters Patent is:

l. A wrapper for a substantially flat ar ticle consisting of a tube haring infolded tucks automatically expansible by the insertion of the article to be wrapped to form linger guiding grooves in 'the overhang'ing portions of the wrapper at both ends of the 'article to be wrapped.

2. A wrapper for a substantially rectangirlar article consisting of a tube o'f greater length than the article to be wrapped and having infolded tucks automatically eX- pansibleby the endwise insertion of the article to be wrapped to form finger .guiding grooif'es of approximately tl-form in the overhang-ing portions of `the wrapper at both ends of the article to be wrapped, and having said overhanging portions infolded and returned upon and secured to one face of the wrapper.

8. A wrapper for a substantially flat article consisting `of a tube of greater length than the article to be wrapped7 and having an intermediate article inclosing portion conformable to thesides of the said article and having infolded tucks automatically eX- pansible by the insertion ofthe article to be wrapped to forni finger guiding grooves in the article7 the side panels of the wrapper' adapted to overlap the ends of the article with said overhanging portions folded over both ends of the article and sealed to the inclosing portion of the wrapper.

Li. A tubular wrapper for a substantially rectangular relatively liat article comprising an open ended sheath having infolded longitudinalv tueln automatically exp'ansible -by the endwise insertion of the article to be wrapped to forni linger guiding grooves in the m'erhanging portions of Vthe sheath at both ends of usaid article, the inturned ends of thc side panels of the sheath being iniold'ed and overlapping the ends of the ar7 ticle to be wrapped, and held in position bv said Voverhanging portions. u
