Description

Technical Field

[0001] The utility model relates to the technical field of acousto-magnetic anti-theft, in particular to a paper acousto-magnetic anti-theft label and its shell. Background Art

[0002] The acousto-magnetic anti-theft soft label is one of the important anti-theft measures for open-shelf sales in the retail industry at present. Due to its performance of being not easily interfered by the outside world and having an extremely low false alarm rate, it is widely used in various retail supermarkets, shopping malls, chain stores and other places around the world. Usually, the acousto-magnetic anti-theft soft label is pasted on the commodity packaging or placed inside the packaging box. After the customer selects the commodity and pays at the cashier desk, the cashier or other staff will demagnetize it. If a thief tries to take the commodity out of the store without paying, the commodity with the un-demagnetized label will trigger an alarm when approaching or passing through the acousto-magnetic alarm system at the store entrance, so as to remind the store staff to stop the thief and thus achieve the anti-theft effect.

[0003] The existing acousto-magnetic anti-theft labels are disposable consumables and will be discarded together with the packaging. The acousto-magnetic anti-theft soft label is composed of multiple layers such as a PS (polystyrene) / PE (polyethylene) plastic composite outer shell film, a non-chip, a semi-hard magnetic sheet, a sealing cover material of PE / PET (polyester) plastic composite film, and an adhesive sticker paper. How to reduce or completely eliminate the plastic usage of the traditional acousto-magnetic anti-theft label shell and thus reduce or eliminate the cumulative plastic pollution caused by this product has become an urgent problem to be solved.

[0004] At present, an acousto-magnetic anti-theft label made of paper material (CN216161189U) has appeared on the market. This label can achieve the purpose of reducing plastic pollution because its material can be decomposed by the environment; its shell is made of paper material. Since the formability of paper is not as good as that of plastic, the inventor of the utility model has found that in the actual shell forming process, cracks or wrinkles are likely to occur at the four corners of the edge of the raised part of the label shell in the hot pressing process environment, and even rupture, resulting in a high defective rate and low production efficiency of the paper label shell. Summary of the Utility Model

[0005] The utility model provides a paper acousto-magnetic anti-theft label to solve the technical problems that the shell of the paper material soft label in the prior art is difficult to produce and prepare, and it is difficult to heat-seal the shell.

[0093] The following further describes in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model. It should be noted that: unless otherwise specifically stated, the relative arrangements and numerical values of the components and steps described in these embodiments do not limit the scope of the present utility model.

[0094] The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present utility model and its application or use.

[0095] Techniques, methods, and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment shall be regarded as part of the specification.

[0096] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0097] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

[0098] Please refer to Figures 1-4 , the present utility model provides a paper acoustic-magnetic anti-theft label housing, including a housing 1 made of paper material, and the housing 1 is composed of a containing cavity body 11 and a housing bottom surface 12 surrounding the opening of the containing cavity body 11;

[0099] The included angle between the side wall surface of the containing cavity body 11 and the housing bottom surface 12 is ≥60° and <90°, and the connecting surface between any two adjacent side wall surfaces is a curved surface.

[0100] Wherein, the connecting surface is a smooth curved surface, and at least a partial section of the cross-section of the connecting surface is arc-shaped, and the radius of the arc is 0.5 mm - 2.5 mm.

[0101] In this embodiment, by making the included angle between the side wall surface of the containing cavity body 11 and the housing bottom surface 12 greater than or equal to 60° and less than 90°, there is an inclined slope between the side wall surface of the containing cavity body 11 and the housing bottom surface 12. Such a slope can provide a buffering effect on the thermal pressing deformation of the paper housing, significantly improving the smoothness and flatness of the forming surface, thereby reducing the uneven stress applied to the housing, and thus reducing the generation of cracks and wrinkles.

[0102] In addition, the rounded corner design of the containing cavity body 11 can effectively protect the housing from damage. During the manufacturing process, if there is no slope and rounded corner between the side wall surface of the containing cavity body 11 and the housing bottom surface 12, the housing may be clamped or damaged. The right-angle design of traditional labels will cause stress to concentrate at the edges and corners of the containing cavity body 11. By using the slope and rounded corner design, the stress concentration can be effectively reduced, and the housing can more easily adapt to shape changes, reducing the risk of damage. Using the slope and rounded corner design can improve the contact situation between the housing and the mold during the forming process, making the paper housing easier to slide and adapt to the shape of the mold, thereby improving the forming efficiency.

[0103] As one of the embodiments, the cross-section of the connecting surface is arc-shaped. It can be understood that the connecting surface may have a regular curved surface or an irregular one due to process problems. This curved surface design can effectively protect the outer shell from damage. During the manufacturing process, if there are no slopes and rounded corners between the side wall surface of the accommodation cavity 11 and the bottom surface 12 of the outer shell, the outer shell may be clamped or damaged. The right-angle design of traditional labels causes stress to concentrate at the edges of the accommodation cavity 11. By using the slope and rounded corner design, the concentration of stress can be effectively reduced, and the outer shell can more easily adapt to shape changes, reducing the risk of damage. Using the slope and rounded corner design can improve the contact situation between the outer shell and the mold during the molding process, making the paper outer shell easier to slide and adapt to the shape of the mold, thus improving the molding efficiency.

[0104] As one of the embodiments, the radius of the cross-section of the connecting surface is 0.5 mm - 2.5 mm, and the angle between the side wall surface of each accommodation cavity 11 and the bottom surface 12 of the outer shell is 75°. The area of the top surface of the accommodation cavity 11 is smaller than the opening area of the accommodation cavity 11.

[0105] According to the experimental data, for the accommodation cavity 11 made of white cardboard with single-sided PE coating, when the angle between the side wall surface of the accommodation cavity 11 and the bottom surface 12 of the outer shell is 70 degrees, the wrinkling rate is about 2%;

[0106] For the accommodation cavity 11 made of white cardboard with single-sided PE coating, when the angle between the side wall surface of the accommodation cavity 11 and the bottom surface 12 of the outer shell is 90 degrees, the wrinkling rate is about 5%;

[0107] For the accommodation cavity 11 made of coated paper with single-sided PE coating, when the angle between the side wall surface of the accommodation cavity 11 and the bottom surface 12 of the outer shell is 70 degrees, the wrinkling rate is about 3%;

[0108] For the accommodation cavity 11 made of coated paper with single-sided PE coating, when the angle between the side wall surface of the accommodation cavity 11 and the bottom surface 12 of the outer shell is 90 degrees, the wrinkling rate is about 7%.

[0109] Since the coated paper is softer than the white cardboard, the accommodation cavity 11 is more likely to wrinkle during thermoforming. Using the accommodation cavity 11 with an inclined side will have a better effect of reducing wrinkles.

[0110] As one of the embodiments, the height of the accommodating cavity 11 is 0.3 mm - 0.55 mm, and the width inside the accommodating cavity 11 is 5.5 - 10 mm. On one surface of the bottom surface 12 of the outer shell, which is on the same side as the opening of the accommodating cavity 11, a plurality of grooves and / or a plurality of raised structures are provided. The distance between two adjacent grooves and / or the raised structures is the same.

[0111] As one of the embodiments, the paper material used for preparing the housing 1 is a paper material with a unit weight of 250 grams per square meter - 400 grams per square meter.

[0112] As one of the embodiments, the paper material used for preparing the housing 1 is any one of white cardboard, single-sided PE-coated white cardboard, double-sided PE-coated white cardboard, single-sided PE-coated copperplate paper, single-sided PE-coated paper, and double-sided PBAT-coated paper.

[0113] The present utility model further provides a paper acoustic-magnetic anti-theft label, which includes a sealing cover material 2 and the paper acoustic-magnetic anti-theft label housing as described above;

[0114] The sealing cover material 2 is sealed and closed with the bottom surface 12 of the outer shell, and a plurality of resonance sheets are provided in the cavity of the accommodating cavity 11;

[0115] A plurality of biasing members are provided on one surface of the sealing cover material 2 facing the accommodating cavity 11.

[0116] As one of the embodiments, the material used for preparing the sealing cover material 2 is any one of single-sided PE-coated white cardboard, single-sided PE-coated copperplate paper, single-sided PE-coated paper, double-sided PE-coated paper, and double-sided PBAT-coated paper.

[0117] The paper acoustic-magnetic anti-theft label can reduce or eliminate the use of plastics in the outer shell of the acoustic-magnetic anti-theft label, thereby reducing or eliminating the plastic pollution caused by this essential consumable widely used in the global retail industry, and providing a more environmentally friendly solution for the use of plastics. Moreover, the paper acoustic-magnetic anti-theft label with a slope and rounded corner design can effectively reduce the stress concentration during the thermoforming process of the outer shell, reduce the generation of cracks and wrinkles, provide better protection and forming effects, and thus improve the product quality and production efficiency.
