Description

Technical Field

[0001] This utility model relates to the field of heat shrink film, specifically to a heat shrink film packaging for bottles and jars with a bottom tray. 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 beverages to be packaged together, which facilitates transportation, storage, and sales. However, current heat shrink film packaging relies solely on film tension for fixation, and the bottom may lack sufficient support structure. Current practices generally use heat shrink film with superior materials and greater thickness, but this also places certain demands on the quality and cost of the heat shrink film. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a heat shrink film packaging for bottles and jars with a bottom support plate.

[0005] To solve the above problems, this utility model provides a heat-shrinkable film packaging for bottles and jars with a bottom tray. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows:

[0006] A heat-shrinkable film packaging for bottles and jars with a base plate includes: a base plate that supports the bottom of several bottles and jars; a heat-shrinkable film, wherein the several bottles and jars form a bottle and jar group, and the heat-shrinkable film has openings at both ends for the bottle and jar group to enter; the heat-shrinkable film, after being shrunk by heat, wraps the base plate and the several bottles and jars, and the openings are located on both sides of the bottle and jar group; wherein the base plate includes a main plate that contacts the bottle and jar group, the top corner of the main plate has a chamfered edge, and the two ends of the main plate have upwardly extending handles that protrude from the openings in the heat-shrinkable film after being shrunk by heat; the width of the base plate gradually decreases from the chamfered edge to the handles.

[0007] As a further improvement of this utility model, the main body plate is octagonal in shape, and the base of the handle plate is connected to the main body plate through a trapezoidal plate, which is an isosceles trapezoid.

[0008] As a further improvement of this utility model, the main body plate, trapezoidal plate, and handle plate are integrated into one piece of material, and the root of the trapezoidal plate has a crease at the junction with the main body plate.

[0009] As a further improvement of this utility model, when the main body plate, trapezoidal plate, and handle plate are unfolded, the chamfered edge coincides with the waist of the adjacent trapezoidal plate on the same straight line.

[0010] As a further improvement of this utility model, the width of the handle plate is equal to the length of the upper base of the trapezoidal plate, and the handle plate has a through handle hole.

[0011] As a further improvement of this utility model, the length of the chamfered edge is less than the diameter of the bottle / can and greater than the radius of the bottle / can.

[0012] As a further improvement of this utility model, several bottles and jars are arranged in a rectangular array on the same horizontal plane, and the length or width of the main plate is equal to an integer multiple of the diameter of the bottles and jars.

[0013] As a further improvement of this utility model, the bottom support plate is made of corrugated cardboard.

[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 for bottles and cans with a base plate as described in this application are:

[0016] First, by using a base plate to support the bottom of several bottles and cans, the problem of insufficient bottom support caused by existing heat shrink film packaging relying solely on film tension for fixation is overcome. The rigid base plate provides stable bottom support for the bottle and can assembly, enhancing the overall structural stability of the packaging.

[0017] Secondly, the handles at both ends of the base plate protrude through the holes in the heat shrink film, making good use of the existing holes. This not only does not affect the heat shrink film's wrapping and fixing of the bottle and can assembly and the base plate, but also forms a structure that is easy for people to grip, making it convenient for users to move or pick up the packaged bottle and can assembly.

[0018] Finally, the design of the base plate width gradually decreasing from the chamfered edge to the handle plate adapts to the structure of the holes at both ends of the heat shrink film, reducing unnecessary pressure from the sharp parts between the base plate and the heat shrink film, allowing the heat shrink film to wrap the whole more closely, preventing the sharp corners of the base plate from piercing the heat shrink film, and also facilitating the handle plate to pass smoothly through the hole.

[0025] The present invention will be further described in detail below with reference to specific embodiments:

[0026] To achieve the purpose of this utility model, a heat-shrinkable film packaging for bottles and cans with a bottom support plate includes: a bottom support plate 2, which supports the bottom of several bottles and cans 101; and a heat-shrinkable film 3, in which the several bottles and cans 101 constitute a bottle and can group 1. The heat-shrinkable film 3 has openings 301 at both ends for the bottle and can group 1 to enter. After shrinking due to heat, the heat-shrinkable film 3 wraps the bottom support plate 2 and the several bottles and cans 101. The openings 301 are located on both sides of the bottle and can group 1. The bottom support plate 2 includes a main body plate 201 that contacts the bottle and can group 1. The top corner of the main body plate 201 has a chamfered edge 2011, and both ends of the main body plate 201 have upwardly extending handle plates 203. Figure 4 As shown, the handle plate 203 protrudes through the opening 301 of the heat-shrinkable film 3 after heat shrinkage. The width of the base plate 2 gradually decreases from the chamfered edge 2011 to the handle plate 203.

[0027] like Figure 3 As shown, after the heat shrink film 3 shrinks due to heat, the opening area of ​​the hole 301 will also become smaller. The heat shrink film 3 will adapt to the shape of the bottle and can assembly 1 and form a concave-convex fitting part 302.

[0028] like Figure 1 As shown, Figure 1 The arrows indicate the assembly direction of the base plate 2, heat shrink film 3, and bottle / can assembly 1. Figure 1 The equal sign indicates the application state of the combined bottle and can heat shrink film packaging with a base plate of this application.

[0029] For clarity, Figure 4Use a dotted pattern to represent the heat shrink film 3.

[0030] The beneficial effects of adopting the above technical solution are as follows: the bottom support plate 2 jointly supports the bottom of the bottle and can assembly 1, making up for the deficiency of insufficient bottom support in traditional heat shrink film 3 packaging. The handle plates 203 at both ends of the bottom support plate 2 protrude from the openings 301 of the heat shrink film 3, forming a natural grip structure for easy handling. The design of the bottom support plate 2, with its width gradually decreasing from the chamfered edge 2011 to the handle plate 203, avoids sharp parts from squeezing the heat shrink film 3 and also facilitates the force transfer between the handle plate 203 and the main plate 201, preventing punctures to the film and making it easier for the handle plate 203 to protrude from the openings 301.

[0031] like Figure 2 As shown, in some other embodiments of this utility model, the main body plate 201 is octagonal in shape, and the root of the handle plate 203 is connected to the main body plate 201 through a trapezoidal plate 202, which is an isosceles trapezoid.

[0032] The beneficial effects of adopting the above technical solution are: after the rectangle is chamfered, an octagon is formed. The octagonal structure of the main plate 201, together with the isosceles trapezoidal plate 202, transitions to the handle plate 203, making the outline of the bottom support plate 2 more in line with the rectangular layout of the bottle and can assembly 1, reducing the local stress concentration of the bottom support plate 2. At the same time, the design of the slanted side of the trapezoidal plate 202 provides a natural transition support base for the handle plate 203.

[0033] In some other embodiments of this utility model, the main body plate 201, the trapezoidal plate 202, and the handle plate 203 are integrally formed of a single sheet material, and a crease is provided at the junction of the root of the trapezoidal plate 202 and the main body plate 201. The crease is a right-angle crease.

[0034] The beneficial effects of adopting the above technical solution are: the main body plate 201, trapezoidal plate 202 and handle plate 203 are made of one piece of material and creases are preset at the junction, which simplifies the processing flow of the bottom support plate 2 and can be quickly formed by one punching.

[0035] In some other embodiments of this utility model, when the main body plate 201, trapezoidal plate 202, and handle plate 203 are in the unfolded state, the chamfered edge 2011 coincides with the waist of the adjacent trapezoidal plate 202 on the same straight line.

[0036] The waist of the trapezoidal plate 202, namely the trapezoidal waist edge 2021, namely the chamfered edge 2011, and the trapezoidal waist edge 2021 are a line segment connected end to end in the unfolded state of the bottom support plate 2.

[0037] The beneficial effects of adopting the above technical solution are: when the plane is unfolded, the chamfer edge 2011 is collinear with the trapezoidal waist edge 2021 of the adjacent trapezoidal plate 202, ensuring the geometric continuity of the chamfer and trapezoidal transition area and avoiding stress concentration in the bottom support plate 2.

[0038] In some other embodiments of the present invention, the width of the handle plate 203 is equal to the length of the upper base of the trapezoidal plate 202, and the handle plate 203 has a through handle hole 204.

[0039] The beneficial effects of adopting the above technical solution are: the width of the handle plate 203 is equal to the length of the upper base of the trapezoidal plate 202, maintaining the mechanical continuity of the handle area. The through handle hole 204 enhances grip stability, prevents hand slippage during handling, and reduces the overall weight of the base plate 2.

[0040] In some other embodiments of this utility model, the length of the chamfered edge 2011 is less than the diameter of the bottle 101 and greater than the radius of the bottle 101.

[0041] Ideally, the length of the chamfered edge 2011 should be equal to the square root of the radius of the bottle 101. However, for simplicity, the length of the chamfered edge 2011 is between 1.3 and 1.5 times the radius of the bottle 101.

[0042] The beneficial effect of adopting the above technical solution is that the length of the chamfered edge 2011 is limited to between the diameter and radius of the bottle 101, ensuring that the main body plate 201 of this chamfer can support each bottle 101 without any sharp parts protruding.

[0043] In some other embodiments of this utility model, a plurality of bottles 101 are arranged in a rectangular array on the same horizontal plane to form a bottle group 1, and the length or width of the main body plate 201 is an integer multiple of the diameter of the bottles 101.

[0044] The beneficial effects of adopting the above technical solution are: the bottles and cans 101 are arranged in a rectangular array and the size of the main plate 201 matches the diameter of the bottles and cans 101 in an integer multiple, so that the bottom support plate 2 accurately covers the bottom of the bottle and can group 1 without redundancy.

[0045] In some other embodiments of this utility model, the base plate 2 is corrugated cardboard.

[0046] The beneficial effects of adopting the above technical solution are: corrugated cardboard has the advantages of being lightweight and low cost.

[0047] In some other embodiments of this utility model, the thickness of the heat-shrinkable film 3 is one of 12μm, 15μm, 20μm, 25μm, 30μm, and 37μm.

[0048] Because of the presence of the base plate 2, the heat shrink film 3 can also be selected to be relatively thinner, since the weight of the bottle 101 is not entirely supported by the heat shrink film 3.

[0049] The beneficial effects of adopting the above technical solution are: the heat shrink film 3 offers multiple thickness options from 12μm to 37μm, which can be flexibly adapted according to the weight and protection requirements of the bottle and can assembly 1, balancing film strength and economy, and avoiding the problems of being too thin and easily damaged or too thick and increasing costs.

[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.
