2 Claims. (01. 229-48) This invention relates a: the manufacture of containers. More particularly, it pertains to improvements in a joint closure or seam construction which is moisture-vapor impervious at least.
to the same extent as remaining portions of the container and the provision of such a joint closure is a principal object of'the invention.
More specifically, an object of the invention is the provision of a Joint closure for ,ilbrous containers in which container walls can be united at a high rate of speed by using a quick-setting glue marginally applied to one end section of a container blank, and .a line of micro-crystalline wax or similar substancedisposed adjacent thereg to to provide a dam or moisture-vapor proof barrier when an opposing end section is brought into sealed relationship'with the end section containing the wax and glue to form a permanent Joint closure.
, 1 Other objects of the invention will in part be obvious and will in part appear hereinafter,
The invention accordingly comprises an article possessing thefeatures. Properties. and the relation of componentsv which will beexemplii'ied in the article hereinafter described and the scope of the application of which willbe indicated in the claims.
erably is disposed marginally along the edge of the blank It or inwardly thereof a suitable distance. Simultaneously with the application of this line of .adhesive or immediately therea'i'ur 'to the ilnal product providing adhesive as well as hardening qualities. There also may be incorporated in the composition petrolatum 5 per cent and butyl stearate 5 per ,cent and each of For a fuller understanding of the nature and objects of the invention. reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:
11:. 1 is a perspective view of a blank of container material with a central section removed illustrating one arrangement of an application of there is indicated generally at Ila blank, for ex.
ample. of suitable fibrous material, such as cardboard or the like. of substantial thickness to be 7 gush a blank or series of blanks prior to being cut. or while still 'in' web form and unwinding from a mill roll. can be runthrough'any suitable straight line gluing ma/chine marginally to receive a strips of qui'ck-settins adhesive It. This adhesive may be either an animaior othersuitable quick-setting glue and pi'eif- .perform these functions.
these will act as suitable plasticizers. Whi le such a composition may have adhesive characteristics. it is not essential that these be relied on since the quick-setting glue or adhesive will be of such character as to be amply suillcient to bind together the Joint closure sections in the formation of a container. v
After these stripes of material have been applied to the blank, the latter is formed into any desired configuration so that opposite edges there-' of are brought into a desired relationship and by the application of a suitable amount of pressure the glue will ilrmly and permanently secure the sections together to form a Joint closure. It has been found that while an ideally permanent Joint closure can suitably be formed by the use of'a quick-setting adhesive, certain gas-impervious or moisture-vapor proof characteristics thereof are lacking. For example, the container blanks themselves are designed to be gas-impervious as well as immune to moisture-vapor transmission throughout the wall structure. This may be accomplished by the application overall to the blank of any suitable material which will "Glassine." cellulose acetate, moisture-proof Cellophane, or any other suitable moisture-proof or gas-impervious medium, such as wax, can be used. However, known glues which are capable of binding together opposits end sections-to form Joint closures for a container are lacking in these desirable qualities.
However, the separate or simultaneous applicaticn of an amorphous war of the character described performs the desired function and is ideally suited to the construction of such concontour, such a micro-crystalline wax can be applied in the manner set forth. With such a barrier the contents of the container, whether they be in liquid'or gaseous form, are prevented from escaping. Likewise, gases or liquids exteriorly of the container are prevented from entering the same because of such a barrier.
It will be apparent that under certain circumstances it might be desirable to interchange the position of the quick-setting adhesive and the wax so that the latter is outwardly disposed marginally along one edge of a container Joint closure section and the glue inwardly disposed adjacent the wax barrier. The glue can also be applied so as to leave room adjacent each side thereof for the application of the wax barrier when circumstances require such an application.
In this manner, an ideal container of any suitable material can be constructed with a joint closure which combines a moisture-vapor proof barrier with the best physical strength characteristics of a combining quick-setting glue.
It will thus be seen that the objects hereinbeiore set forth may readily and emciently be attained and since certain changes may be made in the above article and difierent embodiments of the invention could be made without depart-v ing from the scope thereof, it is intended that all matter contained in the above description or shown in theaccompanying drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the ioilowing claims are intended to cover all of the generic and said stripes of glue and wax and forming a joint closure seam for the wall of said container. said glue securing said blank structure into said container wall formation and said wax being a arrier. layer against moisture-vapor transmi ion betweensaid joint closure and said glue. 1
2. In a container, a Joint closure which comprises in combination, container wall sections secured together by means of a thermo-setting adhesive marginally disposed between said sections, and at least one moisture-vapor proof barrier consisting of a micro-crystalline wax composition disposed between said Joint sections and lying inwardly of said thermo-setting adhesive, said composition containing pure wax which constitutes about to per cent of said composition, and said wall section being formed from a blank having said adhesive and wax marginally applied adjacent each other on the same Iuriao'e oi said blank.
