Description

[Detailed description of the invention] Industrial application field The present invention relates to a cylindrical label that is attached to a packaged object such as a container. This invention relates to a cylindrical label that can be operated reliably.

Conventional technology Like the container (bottle) that generally holds Western liquor,
If the mouth part is closed with a cap, it is necessary to seal the space between them in order to provide pilfer-proof properties.

One conventional example of such a sealing method is a method of tightening the gap between the mouth of the container and the cap using a colored string. However, this method has problems in that the sealing work is troublesome and the cost of materials for the string increases, leading to an increase in costs.

Recently, there has been a method of heat-shrinking cylindrical labels made of heat-shrinkable films such as PVC (polyvinyl chloride), PP (polypropylene), PET (polyethylene terephthalate), and PS (polystyrene) to attach them to containers and seal them. tends to be used frequently.

In such a cylindrical label, a tearing portion is provided in a part of the circumferential direction of the cylindrical label body in order to ensure the opening (tearing) operation. Conventionally known tearing parts include protruding gripping tongues from the upper opening of the cylindrical label body, cuttings to facilitate tearing at both bases of the tongues, and In some cases, perforations were made in the continuous parts to ensure that the tearing action could be carried out reliably.

Problems to be Solved by the Invention However, in the above conventional examples, there have been combinations of tongues and notches, notches and perforations, tongues and perforations, and combinations of tongues and reinforcing tape. Depending on how the label adheres to the container during heat shrinkage, it may become difficult to open the package, or the tear portion may unexpectedly break off from the cylindrical label body during the package opening process, causing the label to become unopened. The drawback was that it could not operate smoothly.

In particular, when attaching a cylindrical label with a tongue on the top to a container that has a stepped part such as a flange at the mouth and is covered with a stopper, the tongue There are disadvantages in that it is difficult to grasp, the direction of the tearing operation tends to vary, and the opening operation becomes even more difficult. It also has the disadvantage that it tends to generate small pieces of dust (divided into two or more pieces) and contaminates the surrounding area.

The present invention was made in view of the current situation, and an object of the present invention is to provide a cylindrical label that can be opened quickly and reliably.

Means for Solving the Problems The present invention is made of a heat-shrinkable cylindrical film, and is provided with a tongue protruding from one open end at one location in the circumferential direction, and on both sides of the tongue at the other open end. In a cylindrical label that has a notch in a corresponding portion and is attached to a packaged object, the portion from the root portions on both sides of the tongue piece to the notch is provided with a notch and a notch, leaving the notch edge. It is characterized in that a tear-promoting part is formed of continuous perforations, and a reinforcing tape is attached between both tear-promoting parts.

The reinforcing tape is a conventionally known reinforcing tape, such as red tear tape, but the material is stronger than the heat shrinkable film used for cylindrical labels and has a sufficient heat shrinkage rate. small,
It is preferable that the material hardly shrinks. That is, when a cylindrical label is fitted onto a container, heat-shrinked, and attached to the same container, the reinforcing tape does not heat-shrink, and the difference in the amount of heat shrinkage between the cylindrical label and the cylindrical label appears on the tongue piece. As a result of the incision lines of the incisions provided at both bases of the tongue piece being pulled to both sides to increase the length, the incisions 4, 4 open as shown in FIG. 4B. Therefore, as shown in FIG. 3B, the tongue piece 2 is curled outward due to the cooperative action of the reinforcing tape 7 and the notches 4, 4, and is rolled up to the outside of the container 10.

Function: In the cylindrical label according to the present invention, notches are provided at both bases of the tongue provided at one open end, and the notch and the continuous perforation form a tear-promoting part, and the tongue is included in the label. Since a conventionally known reinforcing tape (for example, red tear tape) is attached to the entire length of the label in the width direction between both tear-promoting parts, the label is fitted onto the container and is bonded by heat shrinking. As mentioned above, the tongue is curled by the cooperation of the notch and the reinforcing tape, and is rolled up to the outside of the container, making it easy to grasp. The cylindrical label can be opened by tearing and then peeling off the torn portion in the circumferential direction.

Unlike the case where there are only perforations, the tear-promoting part consists of notches and perforations.The notches act as a guide for the tearing operation, allowing the opening operation to be performed smoothly with a small tearing force, and working together with the reinforcing tape to tear the package. Give direction.

The reinforcing tape further prevents the tongue from accidentally breaking off from the label body during the unsealing operation, and also guides the tearing direction in cooperation with the tear-promoting portion.

Furthermore, at the notch edge of the tear-promoting part,
Since there is a remaining part that is not perforated, when the tear-promoting part is torn, the remaining parts connected to it do not break at the same time, and the remaining part in the direction where a larger force was applied depends on the direction of the tearing force. Since only the portion is torn, the tongue piece is prevented from being accidentally broken from the main body of the cylindrical label, and only one piece of debris is removed.

Embodiment An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the cylindrical label according to the present invention, and FIG. 2 shows FIG.
FIG. 3 is an explanatory diagram showing a state in which the cylindrical label is fitted and attached to the container.

This cylindrical label 1 is supplied in a state of being folded in half into a cylindrical shape, and is fitted onto the flange 10a of a container 10 such as a Western liquor bottle with opposing surfaces 9, 9 open (see FIG. 3A).

The material of label 1 is heat shrink film (for example,
The cylindrical label, which is made of polyvinyl chloride) and is in a fitted state, is heat-shrinked and attached to the flange 10a (see FIG. 3B).

In order to tear (unseal) the cylindrical label 1 from the container 10 after attachment, a tongue piece 2 is formed protruding from the lower opening end of the crease on one side of the cylindrical label 1. Notches 3, 3 are provided on the opposite side of 2 (upper opening end). The distance between the notches 3 and 3 corresponds to the width of the tongue piece 2.

Cuts 4, 4 each having a length of 1/4 to 1/5 of the total length (vertical length) of the cylindrical label are provided at the bases on both sides in the width direction of the tongue piece 2, and the notches 4, 4 and the notches 3,
3, there is a remaining part 11 provided near the notch,
Add perforations 5 and 5 except for 11. The cuts 4, 4 and the perforations 5, 5 allow the unsealing operation to be performed smoothly and reliably, and they function as a tear promoting part 8. The lengths of the cuts 4, 4 may be appropriately selected according to the total length of the label of the seal within a range that does not impair the sealing performance.

Between the perforations 5 and 5, the entire length of the cylindrical label 1, including the tongue piece 2, is reinforced with a material that is stronger than the label 1 and has a very low heat shrinkage rate and hardly shrinks due to heat shrinkage. tape 7 (for example,
Attach red tear tape to mark the location. The reinforcing tape 7 provides directionality in the tearing direction and prevents the tongue piece 2 from accidentally breaking during tearing. The reinforcing tape does not heat shrink when attached, and the difference in heat shrinkage with the cylindrical label is the tongue piece 2.
As a result of the incision line being pulled to both sides, the tongue piece 2 is pulled outward, and by working together with the incisions 4 and 4, which are expanded and opened, the tongue piece 2 has the function of curling toward the outside of the container, as shown in FIG. 3B. have

The cylindrical label 1 is made by cutting a long cylindrical film to a predetermined size, and cutouts 3 are formed at positions corresponding to tongues of an adjacent cylindrical label (not shown). be done.

The remaining parts 11, 11 are formed on the notches 3, 3 side of the tear-promoting part 8, and the length thereof is selected to be 1/4 to 1/5 of the total length of the cylindrical label 1. When the cylindrical label 1 is torn by grasping the curled tongue piece 2 when opening the package, the tear promoting parts 8, 8 consisting of the cuts 4, 4 and the perforations 5, 5 work together with the reinforcing tape 7. Therefore, the part connected to the tongue piece 2 is torn, but at this time, the remaining parts 11, 11 do not break at the same time, and depending on the direction of the tearing force, only the remaining part 11 in the direction where a larger force is applied breaks. Therefore, there is an advantage that the tongue piece 2 is prevented from being accidentally broken from the main body of the cylindrical label 1, and only one piece of dust is removed.

Next, the operation when tearing (opening) this cylindrical label will be explained according to FIG. First, tongue piece 2
Grasp the notch 4, perforation 5 connected to 4,
Tear along 5. Then perforation 5,5
Due to the cooperative action of the reinforcing tape 7 and the reinforcing tape 7, it is possible to reliably tear it along the perforations 5, 5. Next, when the tear reaches the vicinity of the notches 3, 3,
Peel off in the circumferential direction shown by arrow B. In this way, only one remaining portion 11 is broken, and the tongue piece 2 is integrated with the cylindrical label 1 to form the container 1 without being accidentally broken.
It will be opened from 0. Note that, of course, the peeling direction is not limited to the B direction.

In this embodiment, the tongue piece is provided on the lower end circumference, but it is also possible to provide it on the upper end circumference. In that case, the notches 4, 4 will also be on the upper end side, and the notches 3, 3 will be on the lower end side. It goes without saying that the present invention can also be applied to containers other than Western liquor bottles and other envelopes.

Effects of the Invention According to the invention described above, since the tongue piece is curled outward, it is easy to grasp, and when the tongue piece is torn along the tear-promoting part, the opening direction is constant and the tearing force is small. If the torn portion is then peeled off in the circumferential direction, the cylindrical label will be easily opened. Further, there is no possibility of generating small pieces of dust and polluting the surrounding area.
