Description

Technical Field

[0001] This invention relates to a sealing device for the neck of a sealed bag. The invention also relates to a assemblies of sealing devices, and sheet-like or strip-like planar materials for manufacturing the sealing devices. Background Technology

[0002] Bags are a common material used for packaging goods. For example, bakeries typically package bread in bags. Such bags often need to be temporarily opened and then resealed to keep the contents fresh. Therefore, a sealing device is required to reseal the bag after each opening. Reusable sealing devices are known in the prior art.

[0003] For example, US Patent 5832568A discloses a strapping device integrally formed from a thin film-like flexible sheet, including a fastening portion with a hole, a narrow wrapping portion extending from one side of the fastening portion for wrapping the object to be strapped, and a hook portion formed at the end of the wrapping portion in an approximately L-shape for insertion and hooking into the hole.

[0004] However, the shape of this device leads to material waste during production; furthermore, such devices are often discarded after use as sealing devices, resulting in waste. Summary of the Invention

[0005] The purpose of this invention is to overcome one or more of the above-mentioned disadvantages.

[0006] According to a first aspect of the invention, a closure device for closing a bag neck is provided, comprising a flat body having a first edge and a second edge; an opening having an opening shape and disposed at the first edge of the flat body for receiving and holding the bag neck; and a tongue having a tongue shape and configured as part of the flat body at the second edge; wherein the opening shape and the tongue shape of the other closure device are selected such that the opening can cooperate with the tongue of the other closure device. The bag can contain items that need to be kept in the bag (e.g., stored in the bag). In order to have a certain volume in the bag to hold items, the bag is typically sealed at the end near the opening. The sealed or sealable portion of the bag may be referred to as the bag neck.

[0007] The closure device includes a flat body. This flat body is typically flexible to facilitate the placement of the bag neck within the closure device or the removal of the bag neck from the closure device. The flat body also typically simplifies manufacturing because the closure device can be stamped, die-cut, laser-cut, or die-formed. The flat body has a first edge and a second edge. The flat body also typically includes two flat surfaces, such as a top surface and a bottom surface. The flat body may include a third edge and a fourth edge to preferably form a generally square flat body.

[0008] The closure device includes an opening. The opening has an open shape. The opening is arranged at a first edge in the body, allowing it to easily receive and hold the neck of the bag. Typically, when pulled or moved in a specific direction or pattern, the neck of the bag, held in the opening, can be easily pulled out of the opening. The bag can then be opened to remove the contents. As a final step, the neck of the bag can be rearranged in the same closure device so that the closure device can be reused again to close the neck of the bag in a simple manner or method.

[0009] The closure includes a tongue. The tongue has a tongue shape. The tongue is part of a flat body at a second edge. Because the tongue is part of the body and the body is flat, the tongue typically extends from the body in a plane (such as a 2D plane).

[0010] The opening shape and tongue shape of the other closure device are selected such that the opening can mate with the tongue of the other closure device. The shapes of the opening, tongue, first edge, and second edge are set such that when the opening of the closure device mates with the tongue of the other closure device in the mating state, the first edge of the closure device contacts or is adjacent to the second edge of the other closure device. This means that during production, the closure device can be created from strips or sheets in the mating state, such as by stamping, impact, laser cutting, or die cutting. Because the first and second edges of adjacent closure devices contact each other, the shapes of the opening, tongue, first edge, and second edge eliminate the need to remove material between closure devices during production. Therefore, the technical effect of the shapes of the opening, tongue, first edge, and second edge is to reduce waste in production. Furthermore, after being used as a closure device, the closure device can be mated to form a chain or even a flat surface. Advantageously, the mating closure device can then be reused as a chain or covering surface (e.g., coaster, wallpaper, etc.). Reusing the closure device after its primary use provides a further and / or also reduces material spillage.

[0011] According to another aspect of the invention, in an embodiment of the closure assembly, the flat bodies include printed patterns, and the printed patterns together form an image. Advantageously, this closure assembly can form a puzzle to improve the closure assembly for reuse as a puzzle. The puzzle can be reusable, for example, as wallpaper or coasters. The puzzle can be infinitely expandable. According to one aspect of the invention, in an embodiment of the closure assembly, the flat bodies together form a rope, chain, plate, or sheet. The rope or chain can be used as a necklace, etc. The plate or sheet can be used as wallpaper or coasters, etc.

[0012] According to another aspect of the invention, the closure assembly according to an embodiment includes a protrusion and a groove. Advantageously, the closure assembly can form a flat surface, typically a large flat surface. The flat surface can be used to form a cover on a specific area. For example, the flat surface can be adhered to a wall for reuse as wallpaper, such as wallpaper in a children's room. For example, the flat surfaces can be bonded together to form a coaster. The fit of the closure, particularly when the tongue and opening of the closure are identical, can continue indefinitely.

[0013] According to another aspect of the invention, flat material strips, such as those laser-cut, die-cut, or stamped, produced from strips, are arranged to form a plurality of mating or non-matting closures according to the invention. In embodiments of the strips, the openings and tongues of the closures are identical.

[0014] According to another aspect of the invention, a flat sheet of material, such as laser-cut, die-cut, or stamped, is arranged and intended to be produced from a sheet into a plurality of mating or non-matting closures according to the invention. In embodiments of the sheet, the opening and the tongue of the closure are identical.

[0015] Detailed description of exemplary embodiments In an embodiment, when a closure device mates with another closure device, a first edge of the closure device contacts, is adjacent to, or is beside a second edge of the other closure device. Placing the edges close to each other advantageously reduces waste during production. The first and second edges can be generally straight to shorten the span of contact, adjacency, or lateral contact. This shortening provides the advantage of reducing the length that needs to be cut during production.

[0016] In this embodiment, the flat body includes a profile. The profile is the outer edge or shape of the flat body. Advantageously, the opening shape is an integral part of the profile. The opening shape typically does not form a closed line, but rather an open shape.

[0017] In an embodiment, the opening is disposed at a first edge in the body and includes a notch forming in the first edge. The opening is typically an integral part of the first edge. Preferably, the opening disposed at the first edge in the body includes an opening shape forming a notch, gap, cut, or groove in the first edge for engagement with a tongue of another closure device.

[0018] In one embodiment, the tongue of the other device fits tightly into the opening. Advantageously, the tongue typically adapts to the opening and completely or entirely fills it. Advantageously, the tight fit of the tongue in the opening can result in the closure of one device relative to the other. In a further embodiment, a first edge of the closure, together with the opening, adapts to a second edge and the tongue of the other closure to secure the two closures relative to each other.

[0019] In one embodiment, the opening and tongue of the other closure can mate in a plane. Making the opening and tongue mate in the same plane simplifies manufacturing. In a further embodiment, the flat body defines a plane; and this plane is the plane of the flat body. This further simplifies manufacturing.

[0020] In one embodiment, the first and second edges are arranged on substantially opposite edges. Opposite edges allow a series of enclosed devices to be produced adjacent to each other, thereby optimizing production by reducing waste.

[0021] In an embodiment, the opening includes a perforation and a channel; the channel is arranged between a first edge of the flat body and the perforation to allow the bag to slide from the outside of the flat body through the channel into the perforation and vice versa. The presence of the channel between the first edge and the perforation improves the retention of the bag neck within the opening. The channel is typically narrower than the size (typically the diameter) of the perforation, causing the bag neck to slide with high friction between the outside of the bag and the perforation through the channel, and vice versa. Because the bag neck (like water) experiences high friction when held within the perforation and when sliding through the channel to the outside, the bag neck is advantageously and better retained within the perforation.

[0022] In an embodiment, the channel includes a bend, preferably a quarter bend. Besides being generally narrower than the opening, the channel may include bends or even multiple bends to advantageously increase friction as the bag neck slides through the channel.

[0023] In one embodiment, the closure device includes at least one protrusion. The at least one protrusion projects into the opening and is arranged to retain the bag. As the bag neck slides from the opening and into the channel, the at least one protrusion increases the friction of the bag neck. Therefore, the at least one protrusion advantageously improves the retention of the bag neck in the opening. In a further embodiment, the protrusion advantageously projects into the opening. In a further embodiment, the protrusion is advantageously arranged near the channel for retaining the bag neck in the opening. In a further embodiment, the protrusion advantageously has a hook shape. In a further embodiment, a second protrusion projects into the opening and is advantageously arranged on the other side and adjacent to the channel for improving the retention of the bag neck in the opening.

[0024] In one embodiment, the closure device includes: a protrusion as part of a flat body; and a groove disposed in the body for receiving and / or engaging with a protrusion of another closure device. In addition to connecting the closure device to other closure devices via a tongue and an opening, this engagement of the groove and the protrusion allows engagement with two other closure devices, making the closure device advantageously adaptable to engagement with multiple other closure devices. The closure device can then engage with at least four other closure devices. The closure device is then suitable for use as a puzzle piece in a larger puzzle. In a further embodiment, the flat body includes a third edge and a fourth edge; the protrusion is disposed at the third edge; the groove is disposed at the fourth edge; and the third and fourth edges are disposed on substantially opposite edges to improve reuse as a puzzle piece.

[0025] In an embodiment, the flat body includes a surface with a printed pattern; and the printed patterns of multiple flat bodies form an image. The printing patterns of multiple flat bodies forming an image improve the closure device for reuse as puzzle pieces in a jigsaw puzzle. In an embodiment, the flat body is advantageously formed from sheet or plate material, simplifying production. In an embodiment, the opening is advantageously arranged to receive and hold the neck of a bag such as a bread bag, fruit bag, candy bag, grocery bag, fruit bag, and / or a bag containing biscuits. In an embodiment, the flat body is advantageously made of metal; such as aluminum; plastic; such as thermoplastic or bioplastic; wood, cardboard, biodegradable materials, and / or cardboard.
