Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label for preventing unauthorized opening which is stuck and sealed on the rim of the lid of a container.

[0002]

2. Description of the Related Art Conventionally, a paper carton, a metal can container, a plastic container, and a bottle container have been used to prevent unintended opening of food containers such as foods during distribution or display to prevent contamination of foreign substances and deterioration of quality. Labels are attached to the lid and the opening of the container body, or a tape coated with an adhesive is wrapped and attached, or a shrink film is applied. As these conventional tamper-evident labels or tapes, polyester or cellophane film or paper is used as a material, and an adhesive is applied to one side of the label.

[0003]

However, the conventional labels, tapes and the like for sealing the lid edge of various containers have many problems in use. That is, the paper label may be weakened and may be torn before opening depending on the humidity condition during storage.

Further, when a conventional cellophane tape is used or a shrink film is used for packaging, there is a problem that a label cannot be accurately attached to a predetermined fitting portion between the lid and the container body by a high-speed packaging machine. It was further,
Before filling the contents, attach a label or film for preventing tampering to the rim of the lid of the container, and invert the container body to fill from other than the container opening, for example, from the bottom of the container,
During the processes of container supply, filling, sealing, cardboard packaging, etc., the lid edges of the container come into contact with each other, causing tears and scratches and stains due to the adhesion of dust, etc., reducing product value and functionality. There was a problem.

In particular, by making the outer diameter of the rim of the container body smaller than the outer diameter of the lid, it is easier to open the fingertips on the lower part of the skirt of the lid, and in the case of a container which is easy to open, the lid is used. Since the outer diameter dimension of the rim portion of the container body is different, it was difficult to accurately attach the label at a predetermined position with a high-speed packaging machine.

[0006]

In view of the above situation, the present invention has a physical strength without impairing the design of the container even in the case of a lid fitting container in which the outer diameter dimension of the lid and the outer diameter dimension of the container main body are different. It is an object of the present invention to provide a tamper-evident label in which tearing, damage, stains, etc. of the label do not occur in the filling and packaging process of the contents.

That is, according to the present invention, a knob portion is integrally formed which protrudes to a side portion of a label body made of a plastic film or a composite material of a plastic film and paper or a metal foil, and is laterally linked to the knob portion. The label is a tamper-proof label in which a tear perforation is provided on the label body, and an adhesive-coated portion and an adhesive-free portion are provided on the back surface of the label body. Also, the present invention
This is a tamper-evident label in which the portion of the label body to which the adhesive is not applied is the folded portion. Further, the present invention is an unauthorized-tampering prevention label in which perforations are linearly provided on the upper side of a folded portion of the label body where the adhesive is not applied. Furthermore, the present invention is a tamper-evident label in which the width of the label body attached to the container lid is longer than that of the portion attached to the container body so that the label body has a T-shape.

The tamper-evident label according to the present invention comprises a plastic film having physical strength such as polyester, polypropylene, polyethylene, vinyl chloride, cellophane, or a composite material of these plastic films and paper or metal foil. As shown in (1), the surface is printed, and the matte varnish is applied on it.
The back surface is provided with a part to which an adhesive is applied, a part to which no adhesive is applied, or a part not to adhere. Then, the folding part of the label is provided on the step part of the lid and the container body where the outer diameter dimensions of the container body and the lid are different. A straight line perforation is further provided above the folded portion of this label. Also,
The width dimension of the portion of the label body attached to the container lid is made longer than the other portions so that the label body has a T-shape.

With such a shape, when the container is sealed as a tamper-proof label, changes in temperature and humidity during distribution and storage, and further warpage of the label due to contraction and expansion of the container and the label are prevented, The seal will not come off. Since a slight gap is easily formed in the folded portion of the label, an adhesive agent is not applied to this portion or the label is processed so as not to have an adhesive action to prevent adhesion of dust and the like.

Further, as shown in FIG. 7, when the container lid is faced downward and the container is supplied to a filling and packaging machine for cardboard packaging, the container lids are brought into contact with each other in the steps of conveyor transportation and sealing / sealing. However, the label is likely to be torn, scratched, or soiled, so attach the label only to the side surface of the lid. Next, if the opening / picking part of the label is provided on the upper end of the lid part or the lower end of the body part of the container body, it may be opened and re-adhered. Perforations are placed horizontally or diagonally upward for easy removal. This perforated part of the label should be placed at the position where adhesive is applied so as not to be broken by the supply of containers, filling packaging, cardboard packaging, compression during distribution, impact, friction, etc., so that it sticks to the body of the container I am doing it.

The opening knob is provided at the contact (R portion) of the container recess with which the lid is fitted and the container body, and is attached so that the tip of the opening knob is raised. Further, the tamper-evident label of the present invention uses the label having the cross-sectional shape shown in FIG. 3, so that once it is opened, the special resin and the adhesive are transferred to the lid and the container body, and the label on the back side of the label. It is also possible that the applied special resin is destroyed and characters or patterns are floated on the label surface.

The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows an overall view of the label of the present invention, FIG. 4 shows a front view in which the label of the present invention is attached to the lid of the can container and the container body, and FIG. 5 is a side sectional view of the same. FIG. 6 is an external view showing the opened state of the label of the present invention. Further, FIG. 8 is a perspective view of a container in which the label of the present invention is sealed. 1 and 4, the material of the label body 1 is a plastic film such as polyester or vinyl chloride. A shaded portion 6 indicates a portion where an adhesive for sealing the label is applied to the container, and a white background portion 3 indicates a portion where the adhesive is not applied or a portion which is processed so as not to adhere. The perforation 5 on the upper side of the label body 1 has a temperature during storage when the label of the present invention is sealed in a container recess (neck-in part) 15 having different outer diameter dimensions of the container lid 18 and the container body body portion 17, The label is placed in the center above the folding part 13 so that the label will not be peeled off due to the influence of humidity. This prevents warping of the label body and dispersion of stress. As for the shape of the perforations, a plurality of perforations are linearly inserted in the shape of a broken line or a dot.

When the label is peeled off at the folding portion 13, the upper perforation 5 is put in the entire label width and cut from the perforation 5. When peeling off the adhesive portion on the lid side, instead of putting perforations in the entire label, put a plurality of perforations in the central portion so that the label does not break during peeling. The perforation 7 on the lower side of the knob portion attached to the label is for peeling the label, and a plurality of perforations are linearly inserted from the knob portion 4 in a dotted line shape or a dot shape. The size of the perforations is set to be 1: 1 to 3 in terms of the ratio of the part where the perforations are not inserted and the part where the perforations are not inserted in consideration of ease of opening and physical strength.

In particular, the position of the knob 4 is the container R which is the contact point between the container recess (neck-in part) 15 and the container body barrel 17.
By making it come to the portion 16, the tip end portion of the picking portion 4 comes to float from the container main body, which facilitates picking. When peeling off the folded portion 13 or the portion sealed to the lid of the container, it is easy to separate the label by making the shape of the knob 4 downward so that the label can be easily opened.

In order to make it easier to lift the knob 4 even with a small label and to easily open it from the perforation, a U-shaped, V-shaped, I-shaped, etc. cut is made at the end of the perforation 7 below the knob 4. It is good to put. The knob 4 for opening the label is provided on the side of the label body with a shape projecting obliquely downward, and further, by inserting a lower perforation 7 which tears the label body sideways in cooperation with the knob 4. If the label is illegally opened, a label that can be easily identified is obtained.

The portion 6 for sealing the label on the lid side is provided with an extension portion 2 to widen the width in order to secure the stability of the seal when the length of the container lid skirt portion 14 is short, and is a T-shaped portion. Label it. Also, the narrower the width of the folded part of the label, the less the film warps during storage and the stability of the seal can be obtained. , It is advisable to reduce the width so that the label does not break or get damaged. In the case where the lid 18 and the container main body 19 are fitted to each other and the outer diameters are different, it is not possible to fold a strong plastic film into a tightly sealed label on the container main body even if the thickness is thin. Since it is difficult, no adhesive is applied to the folded portion 13. In general, it is difficult to specially process a small label part and a non-seal part separately. Therefore, in the present invention, the printing ink is placed on the unsealed portion of the folded portion to eliminate the adhesiveness. As a result, it is possible to prevent black dust or the like from adhering to the adhesive-free portion 3 of the label during the manufacturing process, the distribution process, and the display, thereby maintaining hygiene.

Next, the structure of the film used in the label of the present invention will be described. FIG. 2 shows an example of the structure of the film used for the label of the present invention. Printing is performed on the surface of a plastic film 10 as a base material, a printing ink layer 9 is provided, and a matte varnish layer 8 for protecting the printing ink layer 9 is provided. On the other hand, the back surface is provided with an adhesive agent layer 11 by applying an adhesive agent only to a portion requiring adhesion. Further, in the case shown in FIG. 3, the special resin 12 is placed on the innermost layer on the seal side of the label body 1 and the adhesive 11 is applied on the innermost layer to attach it to the lid 18 and the container body 19 of the container. If the label is illegally opened at the time of distribution and display, the adhesive 11 and the special resin 12 are transferred to the container body 19, and when viewed from the surface of the label, the characters and the pattern due to the special resin 12 are lifted and the label is illegally opened. This is so that it can be easily identified. In the production of the label of the present invention, one having these film constitutions or one obtained by further changing the film constitution may be appropriately selected according to the purpose of use and the desired label may be produced. It should be noted that what is shown here is one embodiment of the tamper evident label of the present invention, and the present invention is not limited to this.

[0018]

Since the present invention is configured as described above, it has the following effects. That is, in the tamper-evident label of the present invention, since the portion of the label body to which the adhesive is not applied is the folded portion of the fitting portion where the outer diameter dimensions of the container body and the lid are different, the outer diameter of the lid and the container body Labels attached to metal cans, plastic containers, glass bottles, etc. of different fitting sizes that prevent damage or tearing of the labels due to contact between the machines or containers during the filling / packing process of the contents The sealing performance is improved, and dust does not adhere.

Further, since a plurality of linear perforations are provided on the upper side of the folding portion, the shrinkage rate and expansion due to the difference in material between the container and the label caused by the temperature and humidity changes during distribution and storage. It is possible to prevent the occurrence of label warpage and peeling due to the difference in the rate and the difference in the outer diameter between the lid and the container body.

Further, since the width of the label body attached to the container lid is increased so that the label body has a T-shape, the container lid side with the label attached is placed downward to fill the contents. Even when the packaging is performed, the end of the label is not contaminated with dust adhering to the conveyor or the like, and tearing or damage does not occur. Further, a knob portion for opening the label is provided on a side portion of the label body, and the knob portion is provided at a position corresponding to a container R portion which is a contact point between the container concave portion where the lid is fitted and the container body body portion. Since it is sealed, the tip of this picking part is lifted up, making it easier to pick. And since the perforation for opening is put in the lower part of the knob part horizontally or diagonally, it is easy to open from the side,
Once opened, the label is destroyed, so it is possible to easily discriminate illegal opening.
