This invention relates to improvements in containers and refers specifically to containers for dry materials in which a reclosable dispensing opening is provided. y Y

5 The utility, objects and advantages of my invention will be apparent from the accompanying drawings and following detail description.

In the drawings, Fig. 1 is a top plan view of a carton provided with the improvements of my invention.

Fig. 2 is a sectional view taken on line 2--2 of Fig. 1.

Fig. 3 is a similar vie'willustrating the closure tab in' upraised position.

Fig. 4 is a similar view showing said tab in reclosed position.

Fig. 5 is a fragmentary perspective view of the carton illustrating the relative positions of the iiaps comprising the carton top.

Fig. 6 is a development of the upper portion of the carton.

Fig. 'Z is a perspective view of the carton, illustrating the closure in reclosed position and held in place by the latch'- M Referring in detail to the drawings, I indicates a 'carton or box particularly adaptable `for containing such dry materials as coifee, tea, soap chips, scouring powder, etc. The carton I may compriseside walls 2 and 3-and end walls 4 and 3o 5, which when the carton is assembled are disposed .respectively opposite each other. The carton may also comprise a suitable bottom (not shown) and a top 6 which latter may comprise

aps

1 and 8 continuations respectively of

side Walls

2 and 3, and flaps 9 alnd I0 continuations respectively of

end walls

4 and 5. When the carton I is assembled and the top 6 closed, flaps 9 and I0 are folded to end abutting relationship; flap 8 is folded over ilaps 9 and I0 in superposed position and'flap 1 is folded over iiap 8 in superposed relation. The respective iiaps are then adhesivelyunited, as will be hereinafter more fully described.

Flap I0, comprising a continuation of end 5, comprising one of the lowermost aps when the top 6 isin'closed position may be provided with perforations II defining an area or tab I2 of substantially trapezoidal shape, one side of the trapezoid so formed comprising one edgeof the flap. 'I'he corresponding flap 9 opposite flap I0 is provided with perforations I3 comprising continuations of oppositeperforated lines I i.' Adjacent the opposite perforated lines Il and adjacent the perforated lines I3, the aps I0 and 9 may be coated with paint orother material I4 which resists the absorption of an adhesive. The lines of perforation I IA and I3 are characterized in that they are readily severable. v

Flap 8, comprising a continuation of side 2 may be provided with perforated lines I5 and I6 and 5 perforated line I1, lines I5 and I6 being characterized in that they are readily severable from the flap 8 and line I1 characterized in that it is readily bendable but not necessarily easily severable. Lines I5, I6 and I1 define a trapezoidal 10 shaped tab IB. Flap 8 is also provided with perforations I9 which join lines I6 at their4 juncture with line I6, lines I9 being characterized in that they are readily severable from the body of ap 8. The areas 20 of ap 8 adjacent lines I5, I6 15 and I9 are coated with an adhesive resisting material similar to the material coating area I4.

Flap 1, comprising the continuation of side 2, is provided with lines of perforation 2|, 22, 23 and 24,

perforations

2l, 23 and 24 being characterized in that they are readily severable and perforated, line 22 being characterized in that it is readily bendable but not easily severable.

Lines

2i, 22 and 23 dene a tab 25 and lines 24 join lines 2| at their juncture with the ends of line 23.

When the top 6 of carton I is initially closed, the entire upper surfaces of flaps 9 and I0 are covered with .an adhesive such as silicate of soda or the like. However, said adhesive is not absorbed by the areas I4. Flap 8 is folded over iiaps 9 and I0 and the lower surface of flap 8 adheres to the unpainted or uncoated portions of said lower iiaps. The upper surface of iiap 8 is then covered with adhesive and fiap'1 is united thereto 35 in superposed relation, the coated areas 20, of course, not adhering to the rear surface of iiap 1. When the aps are thus united, the tabs I2, I8 and 25, and lines of perforation defining said tabs are disposed relatively, as shown best in Fig. 1. 0

To gain access to the contentsvof carton I, the tongue 26 defined by

lines

23 and 24 is pressed downwardly thereby severing

lines

23 and 24. Simultaneously, tongue 21 is also depressed severing lines I6 and I9, as are also the lines I3 45 dening ythe tongue 28 in flap 9. Upon severing these various lines, the

tongues

26, 21 and 28 are depressed beneath the surface of the lowermost ap I0 and the nger of the operator may be inserted beneath the edge of tab I2. An up- 50 ward thrust will cause the severance of lines II iniiap I0, lines Iiinfiap and lines 2l infiap 1. The three tabs I2, I8 and 25, adhesively united may then be raised,'utilizing lines I 1 and 22 as hinges.. Because of the greater arcthrough which 55 thelowest tab I2 must swing, said tab will usually be completely severed from the body' of iiap e I0. In so raising the tabs access may be obtained to the interior of the carton and a portion r all of the contents thereof may be removed by pouring the same therefrom or removing the same by means of a spoon or like utensil.

Many packaged materials when exposed to the air tend to lose their quality. For instance, in the case of tea, spices or coffee, particularly ground coifee, exposure to the air results in loss of aroma which, of course, is detrimental to the resultant flavor or strength of the material. It

is infrequent that when a package of such mate` moisture upon salt, soap chips, scouring powder,

cookies, etc., are notable examples.

Accordingly, as a feature of my invention, means is provided whereby the composite tab 29 may be effectively reclosed and maintained in comparative air-tight position. It will be noted that the tabs I2, i8 and 25 are progressively larger in area in the order named and that the lower ply and to abut thereon, and a lower ply of withdrawn from under and to overlap the overlargest tab is at the top and the smallest at the bottom. This, of ,course, permits the raising of the composite tab 29 from the top 6 but effectively prevents depressing of `said tab into the interior `of the carton. In addition, it will be noted that no lines of perforation connect the outer ends of the lines I3-i 3,

tongues

28, 2 and 26 respectively. Consequently, said tongues if flexed upwardly or downwardly possess a comparatively high degree of resiliency: It will also be noted that the comparative lengths of tabs i8 and' 25 are 'such that tab 25 overhangs tab I 8 adjacent the tongues 2-6 and 2, and that tongue 21 is longer than tongue 26. Therefore, if, upon lowering composite tab ,29 to the plane of the top 6,

tongues

26 and 2 are flexed upward'- ly to permit the end of tab 25 to pass beneath tongue 27, said latter tongue, assisted by the flexure of tongue 26 will serve to urge and retain the composite tab 29 in seated or closed position. In

vother words,

tongues

26 and 21 act as a resilient` latch holding composite tab 29 in seated position and thereby preventing undue exposure of the contents of the carton to the air.

It is to be understood, of course, that I do not' wish to be limited to the precise structure shown and described since my invention is broadly directed to a carton or container top which is characterized inthat it comprises more than one ply. Moreover, any tab size or shape is broadly contemplated in my invention.
