Description

541267 A7 B7 V. Description of the invention () Field of invention: (Please read the precautions on the back before filling out this page) The present invention relates to a triangular-shaped container or other beverage can, in which the patch of the straw insertion part or the patch The cover is formed later, and is a joinable, brittle, barrier material used as an opening for the straw to be inserted. The present invention also relates to a method for forming the brittle material, and a unique method for adding a cover member to a triangular straw inlet. BACKGROUND OF THE INVENTION: A conventional method for manufacturing a straw opening is to add a net or a barrier material to a package substrate. In the manufacturing example where a partial patch is added to the part first, the patch is two or more parts. The removal of the top cover needs to make the straw opening burst and make adjustments in advance, so the patch is easy. Worn. According to some current practices, the penetration of the local patch requires a larger penetration force, which is greater than that required by the extrusion over void method. The mouthpiece of the triangular top must be visible, oxygen-blocking, and puncture capable of penetrating the anticorrosive juice package. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs One of the objects of the present invention is to provide a patch or a cover at the opening of a straw in a container with a triangular top. Another object of the present invention is to provide a patch or a cover with a triangular straw-shaped opening for a container straw, which has the ability to block oxygen from entering, and can be punctured by the straw with a considerable force penetrating the antiseptic juice package.

Description of the invention () The purpose and description of the disclosure: (Please read the precautions on the back before filling in this Page) A patch or cover at the opening of a straw in a container with a triangular top, etc., which contains a brittle barrier film, and the barrier film is added to a carton after the bottom is formed. The fragile film is bonded to the inside of the carton, the bonding energy is supplied from the outside (ultrasonic or inductive), and the bonding energy passes through the paper layer to form a thermoplastic sheet. The addition of patches is based on small parts, which must be held in place by the patch and can be used in small cartons. Brief description of the drawings: Figure 1 shows a container with a triangular top, one of which is the patch provided by the present invention. Figure 2 is the inside view of a carton top panel with a triangular top, with a patch attached to it. Figure 3 is a cross-sectional view of the patch barrier material of the present invention.

Description of the invention () Formed by punching The straw opening 12 is an internal patchworker 4 (Please read the precautions on the back before filling this page) Covered by 'The patch 1 4 surrounds and contacts the product side 16 of the container 1 0 The mouth of the straw is connected. The patch 14 is composed of a barrier film 26, an aluminum foil stiffening layer 24, and a thermoplastic sealing layer 22, wherein the latter is compatible with the low-density polyethylene sealing body. The patch material layer 30 is extruded to form a laminated pattern so as to prevent the layer from decomposing when in contact with the beverage. The patch material can be a 6mm-2.5 4cm diameter straw (1 mil thick polyolefin) with a penetration force of less than * pounds. The patch adding device includes a metering device, a mechanism cut into a certain length, a lathe mandrel with a vacuum, and a bonding energy source, wherein the lathe mandrel is used to place a patch in a carton, and the bonding energy source is located in a package Outside the body. The patch is formed by adding the bottom of the carton, and the damage caused by contact with the filling machine can be minimized. The following table lists a representative barrier structure. The layers are arranged from the inside (product contact side) to the sealing layer 2 2. Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperative Co., Ltd.

Description of the invention () EVOH is vinyl acetate alcohol copolymerization The EVA is a vinyl acetate joint or sealing area, or the sealing layer can cover the entire patch or only a thin peripheral portion of the patch ', wherein the patch material is in contact with the inner layer of the finger box. "There are quite a lot of patch material structures that can be used, and those dyed in various colors or metallic luster are examples. The shape of the patch can be changed and it can be round, dihedral and other desired shapes. Similarly, the triangular top The shape of the opening can also be changed. A twist-cap can also be added to the patch so that it can be opened when the straw is not in use and used for beverage outflow. The patch and / or the barrier of the carton wall The characteristics can be different from each other (although the carton wall does not need aluminum foil blocking material, but externally visible patch cans are required). With an ultrasonic thin wire joint, a small patch can be added where needed The appearance and function of these patches are equivalent to the anti-corrosive block-shaped openings, but no additional parts need to be added when the patch area is used for straw insertion. This is because the joining energy is penetrated by the carton and not through the patch. The reason is that the patch of the present invention can use a more detailed film than the ordinary two-piece type, whose energy is penetrated by the patch. The above embodiments are only examples of the subject matter of the present invention, and those who are familiar with the technology Have to be easily modified or Transformation, but this does not depart from the scope stated in the scope of the patent application attached to the present invention.
