A flexible container is provided. The flexible container includes four panels. The four panels form (i) a body portion; (ii) a neck portion, and a flare portion that extends from the neck portion; (iii) a tapered transition portion between the body portion and the neck portion; and (iv) the neck portion has a reduced width. The flare portion has an expanded end. The width of the flare portion gradually increases from the neck portion to the expanded end.

FLEXIBLE PACKAGE-FORMING MACHINE FOR HORIZONTAL PACKAGING BY MEANS OF FOLDING AND WELDING A FLEXIBLE BAND AND METHOD
20200130316 · 2020-04-30 · ·

The present invention relates to a machine comprising: an unwinding unit (11) for unwinding a flexible band (1), a folding unit (14) of a flexible band (1), a drive unit (31) configured for moving the flexible band (1) in a forward movement direction (DA), a welding unit (16) and a cutting unit (17) for cutting the flexible band, wherein the cutting unit (17) is a laser beam cutting unit (53) separating each individual flexible package from the flexible band (1) and providing a fill opening in each flexible package by means of at least one fill opening cut. The laser beam cutting unit (53) has associated therewith a separator device, movable in a vertical direction and including an insertable separator element (41), interposed between the opposite faces of the folded flexible band (1), in an area adjacent to the fill opening (3), for separating the opposite faces of the flexible band (1) during cutting operations to prevent the fusion thereof.

STAND UP POUCH WITH FITMENT

A flexible pouch for receiving flowable products that includes a fitment having a spout to allow the flowable products to be discharged from the pouch. The flexible pouch is formed from a top and a bottom web of material. A sealant strip is attached to a top edge of each of the top and bottom webs of material. A fitment having a canoe and spout is positioned such that the canoe is positioned between the first and second sealant strips. The height of the canoe and the width of the first and second sealing strips are the same to minimize the amount of sealant material. The first and second sealant strips are sealed to each other along the entire width of the flexible pouch to entrap the canoe of the fitment between the top and bottom webs.

JOINT APPARATUS AND SPOUT SEALING MACHINE
20200108564 · 2020-04-09 ·

A joint apparatus that joins a pouch body to a spout, including: a spout holding unit that holds the spout; a positioning mechanism that positions the pouch body with respect to the spout; and a joint mechanism that joins a pouch mouth of the pouch body to the spout. The positioning mechanism has a pouch-body moving unit that moves the pouch body toward the spout a contact member having a contact part that comes into contact with an end of the pouch mouth, and an absorption mechanism that absorbs a part of a force acting on the pouch body when the end of the pouch mouth comes into contact with the spout or the contact member.

Process for sealing flexible fitment to flexible film

The present disclosure provides a process. In an embodiment, the process includes A. providing a fitment with a base, the base comprising an ethylene/-olefin multi-block copolymer; B. placing the base between two opposing multilayer films, each multilayer film having a respective seal layer comprising an olefin-based polymer; C. flat sealing the base to each multilayer film with opposing heated flat seal bars, the flat sealing forming opposing seal joints at the flattened base ends; and D. point sealing the opposing seal joints with opposing curved seal bars.

Plastic bag making apparatus

An apparatus is improved to successively make plastic bags each of which includes an end surface provided with a spout, by employing the general feeding way of panel material, to be simple in structure, low in cost, high in speed and to make it possible to successively make the plastic bags two by two. A first folded portion is formed in a first web of panel material 1. An aperture is formed in a second web of panel material 2. A spout is inserted into the aperture, the spout and the second web of panel material 2 being heat sealed with each other. The second web of panel material 2 is guided by a guide device 18 to be folded after being heat sealed so that a second folded portion should be formed in the second web of panel material. The spout is turned over by the second folded portion. The second folded portion and the first folded portion are heat sealed with each other while the second folded portion and the second web of panel material 2 are heat sealed with each other about the spout.
