摘要： A gable top type paperboard carton for juices and other pourable product which may attack the integrity of seals is formed with a pour spout fitment attached to one of the two sloping roof panels. The carton is formed so as to exhibit a rectangular cross section transverse to its longitudinal (vertical) axis, to thereby yield a gable top whose sloping roof panels extend upwardly from the narrower carton side walls. In use, the consumer grasps the two widest side walls of the carton by the thumb and one or more other fingers. This is in distinction to grasping the narrower carton sides, which would entail a wider finger grasp or span. The carton includes a V pocket forming panel in a first gusset, the V pocket receiving a V forming point or wedge on the second gusset. A similar V forming pocket and V point may be located on opposite bottom closure panels. Either V forming pocket may be of paperboard or of barrier film. This construction overcomes the problem of abutting tips of opposite gussets which arises when the gussets are necessarily moved towards each other to form longer sloping roof panels, so as to accept a larger diameter pour spout.
摘要翻译： 形成可能侵害密封件完整性的果汁和其他可倾倒产品的山形顶部纸板纸箱，其中安装有两个倾斜屋顶板之一的倾倒式喷嘴配件。 纸箱形成为横向于其纵向（垂直）轴线的矩形横截面，从而产生其倾斜屋顶板从较窄的纸箱侧壁向上延伸的山形顶部。 在使用中，消费者通过拇指和一个或多个其他手指来抓住纸箱的两个最宽的侧壁。 这是区分抓住较窄的纸箱侧面，这将需要更宽的手指抓住或跨越。 纸箱包括在第一角撑板中的V形袋形成面板，V形袋在第二角撑板上接收V形成点或楔形物。 类似的V形成口袋和V点可以位于相对的底部封闭面板上。 V形成口袋可以是纸板或阻挡膜。 这种结构克服了当角撑板必须相互移动以形成更长的倾斜屋顶板时产生的相对的角板的邻接尖端的问题，以便接受更大直径的倾倒口。

摘要： A pour spout carton for extended shelf life paperboard containers, such as those of the gable top type. A dispensing opening is formed, as by die cutting, in a panel of the carton. A pour spout carries a flange extending from the edge of the dispensing hole to a location radically beyond the dispensing opening, the flange sonically bonded to the outer barrier layer along an annular outermost knurled zone. The knurled zone sonic horn configuration yields pour spout attachment times and spout attachment integrity superior to known prior spout attachment methods and spout constructions.

摘要： A gable top carton and a blank for forming it. The upstanding fin at the top of the gable includes two fin forming protions or extensions from each gable panel laminated together. Half of the length of each fin forming gable panel portion is provided with a horizontally extending tear line and also with a plurality of vertically extending cut lines at its midportion, the latter functioning as tear lines. To open the carton, the midportion of the upper edge of the fin is ripped downwardly and thereafter half of the fin removed by also tearing along the horizontal tear lines, to thus open half of the carton top for manual pour spout formation by the consumer. By virtue of the plurality of vertical cut lines on each gable panel fin portion, the initial vertical ripping can take place along respective non-corresponding (non-homologous) vertical cut lines in each of the two fin forming gable portions, thus compensating for any edgewise misalignment of the gable panel fin portions. The carton interior is internally coated with a barrier layer material, as conventional, but the several cuts through the paperboard and the external PE coating do not extend through the barrier layer, thus preserving the contamination inhibiting property of the barrier layer.

摘要： A paperboard carton for containing and pouring liquid has a pour spout fitment adhesively secured to its upper surface and at least partially over a reinforcing patch on said upper surface to spread the upward force exerted by opening the fitment over an area of the carton surface larger than the bottom surface of the fitment so as to prevent the fitment from being torn away from the carton surface. In addition to the force distribution, the tensile strength of the added patch material is much greater than the strength of the carton coating, thus this new patch material becomes the primary seal.

摘要： A pour spout fitment for a flat top or a gable top paperboard container. A flat strip of rigid plastic material is bent over upon itself to form upper and lower strips integrally hinged together. The lower strip carries a plug coplanar with it, the upper surface of the plug adhered to a part of the lower surface of the upper, hinged strip. The lower surface of the plug is sealed to a portion of a barrier extrusion which covers the entire interior surface of the container, the plug being aligned with a dispensing opening through the paperboard, the opening also covered by the barrier extrusion material. For initial opening and dispensing of the container contents, the upper strip is pulled upwardly, carrying with it the plug and the ruptured barrier extrusion material adhered to the plug. The surfaces of the lower strip over which the contents of the container flow during dispensing are thus protected from contamination at all times except during dispensing. In other embodiments, the upper strip is adhered to a second plug, similar to the first, and a vent hole is defined upon initial opening. In still another modification, the forward edge of the fitment extends beyond the carton edge to prevent dripping. A tamper evident tab may be provided on any embodiment, the tab being integral with the upper strip. The tab must pulled up and a seal broken between it and an associated carton wall to permit opening of the carton.

摘要： A pour spout for a paperboard container of either the flat top or gable top type. In one embodiment, a rectangular strip of a rigid plastics material, such as high density polyethylene, is provided with two upwardly liftable, coplanar hinged flaps, integrally formed with the strip. The flaps are aligned with respective vent and pour openings pre-cut in the container top. Upon lifting the flaps from the plane of the strip, an extruded barrier layer (typically a polymer-foil laminate) spanning the pre-cut openings is ruptured and is carried upwardly through the die-cut openings. One opening is a dispensing opening and the other a vent opening. In a second embodiment, a single integral, coplanar and also liftable flap on the rigid strip is employed to define a single pour opening. In a third embodiment, a single integral and copolanar flap on the rigid strip is covered by a flexible strip which is peeled back to expose the flap. The flap is then pushed downwardly to define a single pour opening.

摘要： A pour spout carton for extended shelf life paperboard containers, such as those of the gable top type. A first barrier layer lines the carton interior and a second lines the carton exterior surface. A dispensing opening is formed, as by die cutting, in a panel of the carton. The two barrier layers span the dispensing opening, except for a concentric dispensing hole through them, with the two barrier layers sonically sealed together along an annular zone radially intermediate the dispensing opening and the dispensing hole. The pour spout carries a flange extending from the edge of the dispensing hole to a location radially beyond the dispensing opening, the flange sonically bonded to the outer barrier layer at three radially spaced, concentric zones. The spout screw cap is of a different polymer than the spout, to prevent bonding between the cap and spout. Use of the specific sonic horn configuration and spout dimensions of this invention yields pour spout attachment times of about one half of prior spout attachment methods and spout constructions.

摘要： A pour spout construction particularly adapted for longer shelf life barrier paperboard containers, such as containers of the gable top type. Barrier containers often carry products and the interior surfaces of the former are lined or covered with a barrier layer. According to this invention a dispensing opening is formed in the paperboard and the major barrier layer extends across and covers this opening. An externally threaded pour spout, attached to the container, carries a threaded cap which normally closes the pour spout. This cap carries an innermost annular skirt whose lower edge is adhered to that barrier layer portion which spans the dispensing opening. When the cap is unscrewed from the spout, the innermost annular skirt carries a part of the barrier layer away from its normal, sealing position, thus rupturing the barrier layer and permitting dispensing of the container contents.
