SHIPPING CONTAINER.

Application filed December 24, 1919. Serial No. 347,202.

To all whom it may concern:

Be it known that 1, CHARLES H. CnowELL, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have made a certain new and useful Invention Relating to Shipping Containers, of which the following is a specification, taken in connection with the accompanying drawing.

This invention relates especially to shipping containers which may be so sealed and closed as to be non-pilferable. When the container is once sealed it is not only amply strong for ordinary freight and express shipments, but it is also practically impossible to open the container in such way as not to leave absolute evidence thereof so that pilfering is prevented or detected. This also has another advantage in making it practically necessary to destroy the container in order to remove the goods originally shipped therein so as to minimize or prevent the reuse of the container which when made of corrugated paper board naturally has less strength and stiffness after its initial shipment. The container which may be made of either corrugated paper or fibre board, etc., may advantageously comprise a body in which the one or more side or edge seams are closed or reenforced by body connector or retainer strips of adhesively secured paper or cloth tape which has the ends brought down inside the container body and preferably overlapping therein so that it is practically impossible to thus arrange the ends of this strip after the top and bottom covers are secured to the container. One or more of these covers may have concealed or inside portions cemented to the container body so as to further prevent tampering with or pilfering the closed package and to give addi tional strength the top and bottom seams or edges may be closed and secured by sealing strips of cloth or paper tape which preferably have their seam portions rendered flexible or readily folded which facilitates their application to the container. In some cases it is advantageous to form the container of two nesting container sections so that the top and bottom are thus secured together by the connecting portions of the inner container section which nests within the contamer body and maybe adhesively secured thereto by glue, silicate of soda or the like, throughout any desired parts of these adacent cooperating faces of the nested sections.

In the accompanying drawing showing in a somewhat diagrammatic way several illustrat ve embodiments of the invention,

Fig. 1 is a perspective view of a container partly in section.

Fig. 2 is a partial transverse section thereof taken substantially along the line 2=--2 of Fig. 1"; and

Fig. 3 is a perspective view of another illustrative container of which part has been cut away to show its construction.

In the illustrative embodiment of the invention shown in Fig. 1 of the drawing the container body which may as indicated be formed of corrugated paper board may'comprise the'ends 5 and 7 connected bythe side sections 6 and 6, and if desired these parts may be formed of a single sheet or strip of corrugated paper which is preferably scored or creased transversely of the corrugations so as to make possible the definite sizing and interchangeability of these parts; and it is also desirable to reenfor'ce the creased folds or seams of this container body by adhesively securing thereto fold reenforcing tape such as 11. The ends of this body strip may advantageously be-formed with square or other abutting edges 24 as shown in Fig. 2, and may be secured together by an adhesive cloth or paper body connector or retainer strip 15 which is secured to the side or edge seam and has portions 16 extending over the edges of this material while its inturned ends 14, 17 are brought along the seam on the inside of the container body and may, if desired, be forced into engagement with the edges of the material when this strip is applied with the corrugated paper' body section in substantially fiat position at this point, so that folding of the container section into more nearly fiat position is thus promoted.

' If desired also one or more of the other edge seams may be strengthened and reenforced and protected against pilfering by the application of a seam body retainer strip,

iii

such as 20, of gummed or otherwise adhesive cloth or paper tape which for similar reasons preferably has its ends inturned and secured on the inside of the corresponding seam.

The top and bottom may be secured to this container body in any suitable way and in many cases it is desirable to use an inner container section comprising the top and bottom which may be made of corrugated paper, paper board, or any other suitable material. Bis shown in Fig. 1, the bottom 1 may be formed integral with the top 3 when both of these parts are comprised in the inner container section having the end portions 2 and a, all of which may be conveniently made of creased and folded corrugated paper board in which the creases are preferably reenforced with the adhesively secured reenforcing strips 11 which may be forced into the creased portions 12 to allow accurate folding of this container section, especially when the creases extend transversely of the corrugated paper material. The adjacent ends 8 of this strip of material may be connected in any suitable way as by the uniting strips 13 secured to one or both sides of the corrugated paper material and where this union takes place in a substantially flat face of the container section subsequent folding is not likely to disturb the connection so that all of the edges of this container section are left at substantially full strength. After the goods have been arranged within the inner container section and the outer section or container body slipped over the same into such relative position as is indicated in Fig. l, the parts may be secured in any suitable way and preferably the adjacent cooperating faces of these nested sections are glued or cemented together as by glue 1a which may be applied to one or both of these faces before the container sections are slipped together so that these concealed inside portions are securely united by any suitable adhesive such as glue, silicate of soda or other adhesive composition. Then the sealing strips such as 19, 22 and 21, which are preferably of cloth or paper gummed tape having flexible or yieldable mid-portions to promote folding are applied to the container, and if desired, these strips may be cut and moistened on any suitable machine which moistens, severs and delivers successive series of strips of different lengths suitable for application to such a package. Under these conditions the bottom sealing strips may first be put in place and then if desired the top sealing strips applied to the container so that the joints or seams of the container are thus securely closed and moisture is prevented from entering the container especially if these sealing strips have paralfined or otherwise waterproofed or water resistant outer surfaces or portions.

Such a package has great strength and it is practically impossible to open the package or pilfer material therefrom in such way as to avoid leaving evidence of such unauthorized opening when the container is finally opened at its destination. In this connection the adhesive securing or cementing of the concealed inside portions of the container are desirable and also the use of such inturned ends of the connector or retainer strips are important, since it is of course practically impossible to replace these strips when the two container sections are assembled. in nested positionwithout at once calling attention to the fact that they have been replaced under these circumstances instead of being originally secured in place when the container section was first formed. The customer opening the container naturally cuts through or cuts out the top or bottom so that at least this container section cannot be re-used and the strong adhesive connection between the sections makes it practically impossible to sell either section of the container for reuse on anything approaching a new price basis.

In the illustrative arrangement shown in Fig. 3, the container body may be made of one or more sections of corrugated paper,

fibre board or the like, each edge or side seam where the different pieces of material are united being secured by connector or retainer strips of gummed cloth or paper tape, such as 31, the ends 33 of which may be inturned and secured on the inside of the con tainer body. Similar retaining strips 35 may be applied to the other side or edge seams of the body and preferably have similar inturned ends which minimize or prevent the pilfering from the container for similar reasons. If desired, the container body may be formed of a single strip or piece of corrugated paper board which may be creased at the proper points preferably transversely across the corrugations of the material so as to form the sides or sections 27, 28 and 29, and these creased or scored portions are preferably reenforced by suitable paper or cloth tape strips 11 in a similar Way. In order to cement the top and bottom to the container body in such way that concealed inside portions may be thus glued or cemented the edges of the container body may be given a stepped or rabbeted form as shown, so that these body portions 27 28 and 29 all have the upstanding projecting top and bottom edges 30 within which the top and bottom 25, 26' of similar corrugated paper board or the like may be forced or fitted and then glued or cemented in place by glue or other adhesive 34 secured to these concealed inside portions so as to prevent unauthorized opening of the package without detection. The connector or retainer strip 31 may have the portion 32 brought down inside and secured to the upstanding 1 ,eeoase edge or stepped portion otthis material so as to allow the close fitting of the top and bottom of the container which may be secured by the glue 34 at these points after the desired goods have been placed in the container. Then similar sealing strips 36, 37 and 38 may be applied to the top and bottom edges of the container in a similar way to give added strength and security to the package.
