Abstract

This utility model discloses a heat-shrink film packaging with a pre-cut, tearable top cover. It includes an opening, a group of bottles and jars forming a package, and openings at both ends of the heat-shrink film for the bottles and jars to enter. An easy-tear line is located above the package, intermittently cutting between the inner and outer walls of the heat-shrink film. The easy-tear line is a closed loop, either circular or elliptical, and the portion of the heat-shrink film enclosed by the easy-tear line serves as a disposable top cover. A tear guide hole penetrates both the inner and outer walls of the heat-shrink film and connects to the easy-tear line. The extension line of the easy-tear line passes through the center of the tear guide hole, which has a diameter less than 20mm and greater than 8mm. This utility model, with its top easy-tear line design, allows for partial tearing to access the bottles and jars without removing the entire film. After tearing, the remaining film remains intact, preventing the bottles and jars from scattering.

Description

Technical Field

[0001] This utility model relates to the field of heat shrink film, specifically to a heat shrink film packaging with a pre-cut tear-off top cover. Background Technology

[0002] POF, or heat shrink film, is a multilayer co-extruded polyolefin heat shrink film. It is made by extruding linear low-density polyethylene as the middle layer and copolymer polypropylene as the inner and outer layers using three extruders, followed by die forming and bubble inflation. Heat shrink film is a thermoplastic film that tightly wraps around a product after shrinking when heated.

[0003] Canned beverages such as cola often use heat-shrink film for multi-can packaging. The heat-shrink process tightly wraps the film around the can, allowing multiple cans of beverage to be packaged together, facilitating transportation, storage, and sales. When not heated and shrunken, the heat-shrink film is a tubular shape.

[0004] When selling individually, the heat-shrink film needs to be removed before the canned beverages are placed on the shelf one by one. Nowadays, due to trends or space considerations, if a warehouse-style, shelf-less sales method is adopted, stacks of canned beverages need to be placed there for individual sale. Firstly, consumers need to remove the heat-shrink film when buying individually, causing inconvenience; secondly, if the tearing action is not performed correctly, the heat-shrink film will instantly lose its restraint on the canned beverages inside, causing the entire stack of canned beverages to fall apart. Utility Model Content

[0005] The problem to be solved by this utility model is to provide a heat shrink film packaging with a pre-reserved tear-off top cover.

[0006] To solve the above problems, this utility model provides a heat-shrinkable film packaging with a pre-cut tear-off top cover. To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A heat-shrink film packaging with a pre-cut tearable top cover includes: openings, a group of bottles and cans forming a bottle and can assembly, with openings at both ends of the heat-shrink film for the bottle and can assembly to enter the heat-shrink film; an easy-tear line, located above the bottle and can assembly, the easy-tear line intermittently cutting the inner and outer walls of the heat-shrink film, the easy-tear line being a circular or elliptical closed loop shape, the portion of the heat-shrink film surrounded by the easy-tear line serving as a disposable top cover; and a tear guide hole, penetrating the inner and outer walls of the heat-shrink film and connected to the easy-tear line, the extension line of the easy-tear line passing through the center of the tear guide hole, the diameter of the tear guide hole being less than 20 mm and greater than 8 mm.

[0008] As a further improvement of this utility model, several bottles and cans are arranged in a rectangular array on the same horizontal plane. From a top-down perspective, when the number of bottles and cans in the length direction and the width direction of the bottle and can group are not equal, the closed loop shape of the tear line is elliptical, and the major axis of the ellipse is parallel to the length direction of the bottle and can group; when the number of bottles and cans in the length direction and the width direction of the bottle and can group are equal, the closed loop shape of the tear line is circular.

[0009] As a further improvement of this utility model, the opening after heat shrinkage is located on the side of the bottle and can assembly and at both ends of the length direction of the bottle and can assembly.

[0010] As a further improvement of this utility model, when the tear line is elliptical, the number of tear guide holes is at least two, and the two tear guide holes are located at both ends of the ellipse.

[0011] As a further improvement of this utility model, the tear guide hole is a circular hole.

[0012] As a further improvement of this utility model, the tear guide hole is a C-shaped cutting slit, the space surrounded by the C-shaped cutting slit is a protruding tongue formed by a part of the heat shrink film, the C-shaped cutting slit is a continuous cutting slit, and the two ends of the C-shaped cutting slit are connected to the easy-tear line.

[0013] As a further improvement of this utility model, the outline length of the tear guide hole is greater than the length of any segment of the tear line.

[0014] As a further improvement of this utility model, the thickness of the heat shrink film is one of 12μm, 15μm, 20μm, 25μm, 30μm, and 37μm.

[0015] The beneficial technical effects of using the heat-shrink film packaging with a pre-reserved tear-off top cover as described in this application are:

[0016] With its closed-loop easy-tear design at the top, consumers can directly tear off the top cap, creating an opening at the top of the bottle set to access the beverage inside without removing the entire heat-shrink film packaging. This solves the inconvenience of having to completely tear off the film for individual items in traditional packaging.

[0017] The tear guide hole is precisely connected to the easy-tear line, and its size is controlled between 8mm and 20mm, which fits the thickness of the finger, allowing users to quickly find the point of force and improve the smoothness of the tearing operation.

[0018] After the top cap is torn off, the remaining part of the heat shrink film still wraps and restrains the bottle assembly. The bottom, sides, and top edge of the heat shrink film are still retained, which avoids the situation where the entire bottle assembly loses its fixation and falls apart after the traditional film is torn off, thus ensuring the continued stability of the packaging.

[0026] The present invention will be further described in detail below with reference to specific embodiments:

[0027] To achieve the purpose of this utility model, a heat-shrinkable film packaging with a pre-cut tearable top cover includes: an opening 201; a group of bottles 101 forming a bottle-can assembly 1; and openings 201 at both ends of the heat-shrinkable film 2 for the bottle-can assembly 1 to enter the heat-shrinkable film 2. An easy-tear line 203 is located above the heat-shrinkable film 2 above the bottle-can assembly 1. The easy-tear line 203 intermittently cuts the inner and outer walls of the heat-shrinkable film 2. The easy-tear line 203 is a circular or elliptical closed loop shape. The portion of the heat-shrinkable film 2 surrounded by the easy-tear line 203 serves as a disposable top cover 205. The top cover 205 can be discarded after being completely torn off. A tear guide hole penetrates the inner and outer walls of the heat-shrinkable film 2 and is connected to the easy-tear line 203. The extension line of the trajectory of the easy-tear line 203 passes through the center or arc center corresponding to the tear guide hole. The diameter of the tear guide hole is less than 20 mm and greater than 8 mm.

[0028] Figure 1 This is a diagram for easier understanding. Figure 1 and Figure 2The text uses arrows and equal signs. Arrows represent the assembly direction, and equal signs represent the shape obtained after assembly.

[0029] Figure 2 Use dashed lines to represent the tear-off line 203.

[0030] To clearly show the shape and outline of heat shrink film 2 Figure 3 , Figure 4 The shape outline of bottle group 1 was hidden. Additionally, Figure 4 The top opening 207 in the image has been slightly torn open to make it easier to understand the principle behind it.

[0031] Figure 3 compared to Figure 1 The heat-shrinkable film 2 after heat shrinking has a concave-convex fitting portion 202 that conforms to the surface of the bottle assembly 1.

[0032] In addition, the tear line 203 does not intersect with the side facade corresponding to the bottle group 1.

[0033] The beneficial effects of adopting the above technical solution are as follows: By providing an opening 201 for the bottle assembly 1 to enter the heat-shrink film 2, and by providing a closed-loop easy-tear line 203 above the bottle assembly, the user can tear off this part to form the top cap 205, thus allowing the user to take out and put in the bottle without removing the entire film, greatly improving the convenience of use. At the same time, the tear guide hole penetrating the film layer is connected to the easy-tear line 203, and its size is suitable for finger operation, significantly improving the smoothness of tearing and opening.

[0034] In some other embodiments of this utility model, a number of bottles and cans 101 are arranged in a rectangular array on the same horizontal plane. From a top-down perspective, when the number of bottles and cans 101 in the long direction and the number in the wide direction of the bottle and can group 1 are not equal, the closed loop shape of the tear line 203 is elliptical, and the major axis of the ellipse is parallel to the long direction of the bottle and can group.

[0035] When the number of bottles 101 in the length direction of bottle group 1 is equal to the number of bottles 101 in the width direction, the closed loop shape of the tear line 203 is circular.

[0036] The beneficial effects of adopting the above technical solution are: according to the difference in the number of bottles 101 in the length and width direction of the bottle group 1, the easy-tear line 203 is arranged in an elliptical or circular shape, so that the easy-tear shape is more in line with the actual arrangement of the bottles in the group, that is, the ellipse corresponds to the rectangle, and the circle corresponds to the square, thereby improving the rationality of the tearing operation.

[0037] In some other embodiments of this utility model, the opening 201 after heat shrinkage is located on the side of the bottle and can assembly 1 and at both ends of the bottle and can assembly 1 in the length direction.

[0038] The beneficial effects of adopting the above technical solution are: the opening 201 after heat shrinking is located on the side of the bottle and can assembly 1 and distributed at both ends of the length direction, and the heat shrink film 2 on the top of the packaging bottle and can assembly 1 is flat as a whole, which facilitates the layout of the easy tear line 203.

[0039] In some other embodiments of this invention, when the tear line 203 is elliptical, Figure 2 That is, corresponding to an ellipse, the number of tear guide holes is at least two, with the two tear guide holes located at both ends of the ellipse.

[0040] The beneficial effects of adopting the above technical solution are: when the easy-tear line 203 is elliptical, at least two tear guide holes are provided at both ends of the ellipse, and the user can choose to remove one of them. If one fails, the other can still be used.

[0041] like Figure 4 As shown, in some other embodiments of this utility model, the tear guide hole is a circular hole 204.

[0042] When the easy-tear line 203 is torn open and the top cover 205 is removed, the circular hole 204 is split in two, and one circular hole 204 becomes two approximately semi-circular notches 206.

[0043] The beneficial effects of adopting the above technical solution are: setting the tear guide hole as a circular hole 204, the structure is simple and easy to process, and the stress distribution at the edge of the circular hole is uniform, making it easy for users to apply force to tear it open.

[0044] like Figure 5 As shown, in some other embodiments of this utility model, the tear guide hole is a C-shaped cutting slit 208, and the space surrounded by the C-shaped cutting slit 208 is a protruding tongue 209 formed locally by the heat shrink film 2. The shape of the protruding tongue 209 is approximately semi-circular. The C-shaped cutting slit 208 is a continuous cutting slit, and both ends of the C-shaped cutting slit 208 are connected to the easy-tear line 203.

[0045] The beneficial effects of adopting the above technical solution are: the C-shaped cut 208 and the circular hole 204 have similar effects. The advantage of the C-shaped cut 208 is that it does not completely cut off this part of the easy-tear film 2, thus reducing waste scraps on site.

[0046] In some other embodiments of this invention, the outline length of the tear guide hole is greater than the length of any segment of the cutting line in the easy-tear line 203.

[0047] The beneficial effect of adopting the above technical solution is that the tear lines 203 are relatively closely spaced, making them easy to tear.

[0048] In some other embodiments of this utility model, the thickness of the heat-shrinkable film 2 is one of 12μm, 15μm, 20μm, 25μm, 30μm, and 37μm.

[0049] The beneficial effect of adopting the above technical solution is that the thickness of the heat shrink film 2 is limited to multiple specifications, which can ensure that the film material has sufficient strength and shrinkage performance to securely wrap the bottle and can assembly.

[0050] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
