Problems solved by technology

[0019] A first disadvantage of this known solution is that the system can only be closed using flexible label closure sheets
[0020] In addition, this solution requires separate conveyors for the label closure sheet and the label gluing unit, which increases production and maintenance costs

Embodiment Construction

[0048] Referring to the accompanying drawings, there is shown a semi-automatic closing system for flexible containers, generally designated as reference numeral 1, for closing a container C, wherein the container C has an open end A through which the product contained therein can be removed .

[0049] In a non-limiting example, the container C can be made of flexible material such as paper, plastic and / or degradable material, and can hold any kind of product, including food, without specific limitation.

[0050] The system 1 comprises a reel B for receiving the winding of a deformable roll film N, the reel B having a strip 4 made of a semi-rigid deformable material, the upper edge 4A and the lower edge 4B of the strip 4 facing respectively Opening A and bottom B of container C.

[0051] As is well known, the strip 4 may be substantially flat, made of metal such as aluminum or of paper or polymeric material, the strip 4 includes a wire-like core 4C made of metal or non-metalli...

Abstract

A semi-automatic sealing system (1) for flexible containers (C), comprising a roll of continuous deformable roll film (N) and a semi-automatic device (2) for sealing the containers (C) with the roll film (N), where the device (2) comprises a frame (5) comprising a recess (6) for receiving an open end (A) of one container (C) at a time, a feeding device (7) for feeding the roll film (N), a cutting device (8) for cutting the roll film (N), and a deformation sealing device (9). According to the invention, the roll film (N) has integrally connected labels (E) at substantially a fixed distance (d) from each other to form a labelled roll film having a predetermined cross-section, the cutting device (8) is used to cut the roll film (N) into segments (4 ', 4' ') having a length (I) equal to the distance (d) to form the labelled sealing sheet (3), while the labels (E) are located in the middle of the segments (4', 4 ''). Furthermore, deformation sealing means (9) cooperate with the cutting means (8) to deform and seal each labeled sealing sheet (3) around the open end (A) of one container (C) at a time while keeping the label (E) in the central position of each container (C). The frame (5) has a substantially horizontal plate (12) and at least one vertical reinforcing wall (13), and wherein the feeding device (7) comprises a channel (10) extending along the wall (13), the cross-section of which is larger than the roll film (N) with labels, avoiding any deformation of the labels (E) during feeding.

Description

[0001] field of invention [0002] The invention is generally applied in the field of flexible container packaging systems, and in particular relates to a semi-automatic sealing system for flexible containers. Background technique [0003] The field of packaging systems has long used containers made of flexible materials such as plastic, paper, and / or biodegradable materials, into which one or more products are placed and / or removed from the container opening, and then used with strings, strips, etc. Tape or any other rigid or semi-rigid sealing member closure. [0004] Typically, when packaged with a closure member, the user can remove the closure member, reopen the container, and take out the product through the opening. [0005] In particular, it is common in the art to use strips or strips as closure sheets, usually made of polymeric or metallic materials, which are fed from reels and cut to size prior to the sealing step, wrap around the container opening, and then seal ...
