Patented July 6, 1943 SEALING STRUCTURE FOR CONTAINERS Isaac L. Wilcox, Fulton, N. Y., assignor to OS- wego Falls Corporation, Fulton, N. Y., a corporation of New York Application April 5, 1940, Serial No. 328,079
' '1 Claims. (Cl.-22943) This invention relates to containers formed of sheet fibrous material, such as paperboard, and is directed particularly to a structure for sealing the top member or cover to the body of the container.
Containers of this type are usually manufactured and shipped to the user with a portion of the cover or top member unsecured to the body to provide an openin through which the container may be filled, and this unsecured portion'of the cover is then sealed to the body of the container. Accordingly, the unsealed portion of the topedge of the body is exposed until the container has been filled and sealed, with the result that such exposed portion may be contaminated, or rendered unsanitary, by persons handling the con tainer previous to the time that it is filled and sealed. Also, the confronting surfaces of the top member and body member are sealedin such a manner that when the seal is broken the raw material, from which the container is formed, is exposed and is contacted by the contents of the container as the same ispoured from the container with the result that containers formed of' fibrous material, such as paperboard, absorb the liquid contents during the pouring operation, whereupon the absorbed liquid is subjected to particularly rapid bacterial action.
The present invention has as an object a container of the type referred to embodying a top structure providing an effective impervious seal between the top of the container and the body thereof. which seal is conveniently broken to permit the container to be opened and during the breaking of the seal a sterile impervious surface is provided over which the contents of the container will pass in being removed from the container.
The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.
In describing this invention, r ference is had to the accompanying drawings 11 which like characters designate corresponding parts in all the views.
Figure 1 is a container embodying my invention shown in perspective .and'in sealed condition.
Figure 2 is a perspective view, similar to Figure 1, showing the container in unsealed and open condition.
Figure 3 is an inverted plan view of the cover member before the same is attached and sealed to the body of the container.
Figure 4 is a sectional view taken substantially on line 44, Figure 1.
Figure5 is a reduced top plan view of the conv tainer in sealed condition.
Figure 6 is an enlarged fragmentary sectional view illustrating the top portion of the container in unsealed open condition for the reception of the contents.
Figure 7 is a view, similar to Figure 6, illustrating the container in sealed condition.
Figure 8 is a view, similar to'Figures 6 and 7, illustrating the container after the same has been unsealed and opened.
The container consists of a tubular body member I0 which may be of any desired cross sectional form and which maybe formed from a blank of sheet material, such as paperboard. The body It] .is provided with a suitable bottom closure which may include tabs ll foldable over the bottom edge of the body and effectively sealed to the outer surface thereof. The container is Eompleted by atop member l2'which may vary in form in accordance with the shape or contour of the body l0.
As previously stated, my invention has to do particularly with the structure for effectively sealing the top member to the body after the contents has been placed in the container. Accordingly, the form or arrangement of the body, bottom member and top member may be varied appreciably without affecting the sealing structure hereinafter described.
In the embodiment shown, the body is rectangular in cross section and the cover blank is scored at I3 to form peripheral flanges it, IS. The flanges M, l5 are also scored at l6 to form peripheral flanges or tabs IT, and the flange I5 is scored as at l8 to form a flange I9. The flanges l4, l5 and H, H are complemental. The flanges M are bent upwardly to extend in parallel relation to the inner surface of the sides of the body In, and the tabs H are folded downwardly about the outer surface of the sides of the body. The flanges I4, I! are initially secured and sealed to the inner and outer surfaces of the adjacent sides of the top portion of the body, the flanges l5, [9 being unsecured to the the tab I9 is of appreciably greater width than the complemental tabs l1, see Figure 3. g
The cover member is also provided with score lines 20 extending inwardly fromeach corner and converging to meet a transversely extending scor line 2|, and a score line 2; extends wardly from the outer edge of the tab l9 to the score line 2|.
The side of the body adjacent the tab 19 is provided with a transversely extending score line 24 spaced downwardly a distance from the top edge of that side and with a pair of converging score lines 25 extending upwardly from the ends of the score line 24 and meeting at the top edge of the container. With this arrangement, lateral pressure on opposite sides of the container cause the side panels 26 and a central panel 21 to move outwardly and simultaneously effects a ridge formation in the forward panels 28 of the cover member, as illustrated in Figure 2, forming an opening 29 through which the container may be filled, or the contents may be poured or removed therefrom.
The interior of the container, including the inner surface of the top and bottom members, is
provided with a coating 30 to render the inner surface of the container impervious. This coating is in the nature of a thermoplastic and also serves to unite and seal the flanges l4, I! to the top edge of the adjacent sides of the body It].
The container is shipped to the user with the tab l9 folded downwardly over the panels 26, 21, as illustrated in Figure 4, but not sealed thereto. The tab I9 is folded upwardly, and the panels 26, 2! moved outwardly to form the opening 29,
as shown in Figure 2, to admit the contents and thereafter the panels 26, 21 are permitted to assume their normal position and the tab l9 folded downwardly over the panels and sealed to the front side of the container. The container is opened by pulling the tab l9 upwardly, unsealing it from the container and the contents is poured through the opening 29 over the top edges of the panels 26.
This invention has to do particularly with the. structure for effecting a seal between the tab [9 and the adjoining side of the container and in presenting the top edges of the panels 26 in a sterile conditionwhen the container is unsealed. This structure consists generally of a strip of impervious sheet material secured either to the inner surface of the tab l9 or to the upper portion of the panels 26, the exposed surface of the strip being coated with a substance sealable to the other member but being readily separable from the strip when the tab 19 is moved out of engagement with the panels 26.
The strip of impervious sheet material is indicated as at St and may be formed of any thin, flexible, impervious material, metal foil being particularly well suited for this purpose.
In the embodiment shown, the strip 3| is secured to the inner or under side of the tab IS. The exposed side or surface of the strip is pro vided with a coating 32. This coating possesses the characteristic of being sealable to the top portion of the panels 26 to seal the tab l9 thereto. The coating 32 adheresto the panels. in such a manner as to be permanently secured thereto with sufficient adhesion to cause the coating to peel or strip from the strip material 3| when the tab is forcibly pulled outwardly from the container. This coating may consist of any one of a number of suitable materials, for example a thermoplastic in the nature of co-polymer of vinyl acetate andvinyl chloride. in which instance the coating 32 is applied to the metal foil 3l and is baked thereon in order to have suflicient adhesion thereto to form an effective and proper seal between the side wall of the container and the top member.
However, this adhesion between the coating and the metal foil is not as great as the adhesion between the coating and the fibrous material of the container or panels 26. Accordingly, when the tab I9 is pulled outwardly and upwardly the coating 32 will remain secured to the side wall of the container and forms a sterile surface over which the contents of the container is poured. Also, the now exposed surface of thestrip 3| is sterile and when the tab I9 is folded downwardly over the coating 32 to close the opening 29 for the temporary protection of any of the contents remaining in the container, the coating 32 does not become contaminated by engagement with any unsterile portion of the cover.
In order to insure a perfect and permanent seal between the coating 32 and the top portion of the panels 26, that portion of the panels may be provided with an additional coating 40 which also serves to make the top edge of the panels impervious. The coating 40 may be applied in any suitable manner. However, I have found it most effective to apply the coating in the nature of a tape of coating material preferably formed of the same material as the coating 30. The tape is applied to the top edge of the panels 26 and extends downwardly over the inner and outer surfaces thereof and is bonded thereto.
The foil strip 3| is preferably provided with a coating on both sides, the coating 4| coacting with the coating 30 on the inner side of the tab l9 to permanently secure the foil strip to the tab. If desired, the foil strip 3i may be initially permanently secured to the panels 26, or the coating 40, and the tab l9 secured to the foil strip after the container has been filled. In either event, the arrangement is such that the coating 32 or 4| will sever or strip from the coating when the container is unsealed.
The container structure herein described is particularly durable and rugged and due to the fact that the flanges 14, I5 are sealed to the inner surface of the side walls of the body and the flanges l1, l9 are sealed to the outer surface of the side walls, the top closure is firmly sealed to the body of the container and is leak-- proof for all liquids.
