Description

[Technical field]

[0001] The present invention relates to a packaging sheet used for packaging various articles. [Background technology]

[0002] Packaging sheets for packaging various items are widely used in various industries. Among these, in the retail industry, one or more products are wrapped in a packaging sheet when they are displayed in a storefront, and the products are sold at retail in packaged units. Packaging sheets used in the retail industry must be low cost, since they are often used to package low-priced items, and they must also be easy to use, since items are delivered in boxes and employees wrap them one by one, or in small batches. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7298990 Summary of the Invention [Problem to be solved by the invention]

[0004] An example of such a packaging sheet is disclosed in Patent Document 1. Patent Document 1 discloses a packaging sheet with a label having an adhesive portion. This packaging sheet is configured such that the sheet body is folded and one end of the sheet body is secured with a label at its opposite end. The label is entirely adhesive except for an area 3C on the tip side of the part attached to the other end. This packaging sheet is used by pinching the non-adhesive area 3C and peeling the label from the other end of the sheet body, unfolding the sheet body, and then covering an item with the label to package it.

[0005] The packaging sheet is structured such that the sheet body cannot be unfolded unless the portion of the label attached to the other end is peeled off, which makes the packaging process difficult. When the label is peeled off, the adhesive area attached to the other end is exposed, so the label is likely to stick to an unintended location when the sheet body is unfolded. In addition, because the sheet body must be folded before being transported to the work site, creases inevitably appear on the sheet body, which can make the sheet look unattractive and, in some cases, can be an obstacle during packaging work.

[0006] The invention of the present application has been made to solve these problems, and has an object to provide a labeled packaging sheet that has a structure that does not require the label to be peeled off when the sheet is unfolded for packaging, eliminating the problem of the peeled label sticking to an unintended location, and does not require the sheet to be folded when carried to the work area. [Means for solving the problem]

[0007] In order to solve the above problems, this specification discloses an invention for a labeled packaging sheet. The labeled packaging sheet according to the disclosed invention is a labeled packaging sheet that is made up of a sheet body and a label with one side surface locally adhesive, and when an article is wrapped around the sheet body, a certain area on the periphery of the sheet body and another area on the sheet body are secured by the label. In this labeled packaging sheet, one side of the label is composed, in the longitudinal direction, of a first adhesive portion, an intermediate non-adhesive portion, and a second adhesive portion, and at least the second adhesive portion is an adhesive portion that can be peeled off by hand and re-adhered. In addition, in this labeled packaging sheet, the label is folded in two with the surface on one side forming a valley and a fold line formed in the middle non-adhesive portion, the first adhesive portion adheres to the surface of a certain part of the peripheral portion of the sheet body, the part forming the valley in the middle non-adhesive portion straddles the edge of the sheet body, and the second adhesive portion adheres to the sheet body on the side opposite to the surface of the certain part of the peripheral portion to which the first adhesive portion adheres. Furthermore, in this labeled packaging sheet, the first adhesive portion and the second adhesive portion of the label are not adhered to each other, and on one side of the label, the area between the second adhesive portion and the longitudinal edge of the second adhesive portion is a non-adhesive portion. In addition, in order to solve the above problem, the labeled packaging sheet of the disclosed invention may have a configuration in which the portion of the intermediate non-adhesive portion where the fold line is formed is in contact with the edge of the sheet body or is spaced 5 mm or less from the edge. In addition, in order to solve the above-mentioned problems, the labeled packaging sheet of the disclosed invention may have a configuration in which a first adhesive portion of the label is an adhesive portion that can be peeled off by hand, and on one side of the label, a non-adhesive portion is formed between the first adhesive portion and the longitudinal edge of the first adhesive portion. In order to solve the above problem, the labeled packaging sheet according to the disclosed invention may be configured to be bag-shaped in a portion other than the peripheral portion where the certain portion is present. In order to solve the above problems, this specification discloses a labeled packaging sheet set. The labeled packaging sheet set according to the disclosed invention is a labeled packaging sheet set formed by stacking a plurality of the labeled packaging sheets described above. In this labeled packaging sheet set, each labeled packaging sheet is folded over in its entirety, and is folded with the peripheral portion where the certain portion to which the first adhesive portion is adhered being located at the top. Effect of the Invention

[0008] As described below, according to the labeled packaging sheet of the disclosed invention, even when it is provided folded, there is no need to peel off the adhesive part of the label when unfolding the sheet body to wrap an item. This prevents the label from adhering to unintended locations during packaging work, making packaging work easy. In addition, since the sheet body can be provided without being folded, packaging can be performed without creases, and deterioration of the appearance can be avoided. In addition, the first adhesive portion and the second adhesive portion of the label are not adhered to each other, which also makes it easy to peel off the label. Furthermore, since a non-adhesive portion is formed between the second adhesive portion and the longitudinal edge of the second adhesive portion on one side of the label, it is easy to pinch the non-adhesive portion and peel the second adhesive portion off from the sheet body, which also makes the label easy to work with. Furthermore, since the portion where the fold line of the intermediate non-adhesive portion is formed is in contact with the edge of the sheet body or is spaced 5 mm or less from the edge, the label does not protrude significantly from the edge of the sheet body, so that the label is less likely to bend or get caught on something when packaging a large number of labeled packaging sheets, and the label will not be torn. Furthermore, a configuration in which the first adhesive portion is an adhesive portion that can be peeled off by hand, and a non-adhesive portion is formed between the first adhesive portion and the longitudinal edge of the first adhesive portion on one side of the label, is preferable because it makes it easy to separate the label from the sheet body when disposing of it after use. Furthermore, by configuring the packaging sheet in a bag-like shape except for the peripheral portion where the label is attached, the above-mentioned effects can be obtained in the bag-like packaging sheet. In addition, according to the labeled packaging sheet set of the disclosed invention, each labeled packaging sheet is folded with the peripheral portion to which the first adhesive portion is adhered at the topmost position, so that the sheet body can be unfolded by pinching and pulling the peripheral portion located at the topmost position, and after wrapping an item, the label can be peeled off by pinching again the non-adhesive portion of the edge of the label at the pinched peripheral portion. This makes it easier to use each labeled packaging sheet for packaging while providing it in a compact state. [Brief description of the drawings]

[0010] Next, a description will be given of modes for carrying out the present invention (hereinafter, referred to as embodiments) Fig. 1 is a schematic perspective view of a labeled packaging sheet of a first embodiment. The packaging sheet of the first embodiment is a single sheet for wrapping and packaging an article. This packaging sheet is composed of a sheet body 1 and a label 2, one side of which is locally adhesive. As shown in Fig. 1, in this example, the sheet body 1 is rectangular. The sheet body 1 is made of a plastic material such as polypropylene, polyethylene, polyvinyl chloride, etc., and is a thin sheet with a thickness of about 20 µm to 200 µm. The sheet body 1 is often transparent, and is appropriately printed with a product name, etc., depending on the item to be packaged.

[0011] As shown in Fig. 1, the label 2 is provided in a certain portion of the peripheral portion 11 of the sheet main body 1. In the example shown in Fig. 1, the label 2 is provided in a portion approximately in the center of the peripheral portion 11 along the short direction on the left side of the sheet main body 1. One side of the label 2 is an adhesive surface, and an adhesive portion is provided locally. Figure 2 is a schematic diagram showing the adhesive portion of the label 2, where Figure 2(1) is a perspective schematic diagram and Figure 2(2) is a cross-sectional schematic diagram. In Figure 1, the label 2 is folded, but for the sake of explanation, in Figure 2 it is in an unfolded state.

[0012] In the example shown in Fig. 2, the upper surface of the label 2 is an adhesive surface. The lower surface does not have an adhesive portion, and is entirely non-adhesive. As shown in Fig. 2, the upper surface of the label 2 has a first adhesive portion 21, a middle non-adhesive portion 22, and a second adhesive portion 23 in the length direction. In this embodiment, both ends in the longitudinal direction of one side of the label 2 (the upper side in FIG. 2) are non-adhesive. That is, a first non-adhesive end 24 is provided between the first adhesive portion 21 and the longitudinal edge on the first adhesive portion 21 side. A second non-adhesive end 25 is provided between the second adhesive portion 23 and the longitudinal edge on the second adhesive portion 23 side. The length of each of the non-adhesive ends 24, 25 (shown as L1 in FIG. 2(2)) is a small length of about 0.5 to 2 mm.

[0013] Each of the adhesive portions 21, 23 has an adhesive property that allows it to be peeled off by hand while adhered to the sheet main body 1 and to be re-adhered to the sheet main body 1. Each of the adhesive portions 21, 23 is formed by applying an adhesive material having such adhesive properties. The intermediate non-adhesive portion 22 is formed by either not applying any adhesive or by applying a coating of a material that eliminates the adhesive force of the adhesive (so-called glue-killing). The same is true for the non-adhesive end portions 24, 25, which are formed by either not applying any adhesive or by glue-killing.

[0014] Fig. 3 is a perspective schematic diagram showing the attachment of the label 2 to the sheet body 1. As shown in Fig. 3(1), the first adhesive portion 21 of the label 2 is first attached to the sheet body 1. The attachment portion is a portion located at a distance from the edge of the sheet body 1 that is approximately half the length of the intermediate non-adhesive portion 22 (shown as L2 in Fig. 3(1)). After the first adhesive portion 21 is attached, the label 2 is folded in two as shown by the arrows in Fig. 3(2). The folding is performed so that one surface on which the first adhesive portion 21 etc. is formed becomes a valley and a fold line (shown by the dashed line 221 in Fig. 3(2)) is formed in the intermediate non-adhesive portion 22.

[0015] Then, as shown in Fig. 3(3), the second adhesive portion 23 on one side of the folded label 2 is placed against the sheet main body 1 and adhered to it. The surface to which the second adhesive portion 23 adheres is the surface (back surface) opposite to the surface to which the first adhesive portion 21 adheres. At this time, as shown in Fig. 3(3), the intermediate non-adhesive portion 22 forming the valley straddles the edge of the sheet main body 1, and the fold line 221 is in close proximity to the edge of the sheet main body 1. In other words, the fold line 221 of the intermediate non-adhesive portion 22 is in contact with the edge of the sheet main body 1 or is in close proximity to it at a short distance.

[0016] In the state shown in Fig. 3(3), the labeled packaging sheet of the embodiment is completed as a product. In this state, a large number of labeled packaging sheets may be stacked and placed in a box or the like for shipping, or may be folded and compact for shipping. An embodiment in which a plurality of labeled packaging sheets are stacked and provided can be called a labeled packaging sheet set. An embodiment of the labeled packaging sheet set of the invention will be described below. Fig. 4 is a perspective schematic diagram of a labeled packaging sheet set according to an embodiment.

[0017] As shown in Fig. 4, when the labeled packaging sheet is provided in a folded state, it is folded by making fold lines along the short side at several points in the longitudinal direction. It is then folded with the peripheral portion 11 on which the label 2 is provided being positioned at the topmost side. A labeled packaging sheet set is made by stacking a number of labeled packaging sheets folded in this way and packaging them in a box or an outer bag.

[0018] A method of using the labeled packaging sheet of the first embodiment shown in Figures 1 to 3 will be described with reference to Figure 5. Figure 5 is a perspective schematic diagram showing a method of using the labeled packaging sheet of the first embodiment. In Figure 5, cut Chinese cabbage is assumed as the article to be packaged. A whole cabbage is too large for one family, so supermarkets and other retailers sell it cut into quarters or eighths. If it were to be displayed on the sales floor as cut, it would be unhygienic and unattractive, so it is wrapped in wrapping paper before being displayed.

[0019] When such packaging is performed using the labeled packaging sheet of the first embodiment, as shown in Figure 5 (1), the uppermost peripheral portion 11 of the folded sheet body 1 is pinched and lifted, and the sheet body 1 is unfolded. 5(2), the cut Chinese cabbage (hereinafter, cut Chinese cabbage) g is wrapped with the sheet body 1. At this time, the sheet body 1 is wrapped with the surface to which the first adhesive portion 21 of the label 2 is attached facing up. Then, as shown by the arrow in Fig. 5(2), the second non-adhesive end 25 located on the lower side of the label 2 is pinched and pulled to peel off the second adhesive portion 23. The second adhesive portion 23 is then re-adhered to the peripheral portion along the side of the sheet body 1 opposite to the peripheral portion 11 on which the label 2 is provided. At this time, the peripheral portions on both sides of the sheet body 1 are slightly overlapped. This completes the packaging of the cut Chinese cabbage g as shown in Fig. 5(3).

[0020] According to the labeled packaging sheet of this embodiment, even when it is provided folded, when the sheet body 1 is unfolded to wrap an article, it is not necessary to peel off the adhesive portion of the label 2 (the second adhesive portion 23 in the above example). Therefore, the label 2 does not stick to unintended parts during the wrapping operation, and the packaging work can be easily performed. In addition, since the sheet body 1 can be provided without being folded, packaging can be performed without creases, and deterioration of the appearance can be avoided.

[0021] On the other hand, as shown in Fig. 4, in the labeled packaging sheet set of the embodiment in which a plurality of labeled packaging sheets are provided in a folded state, the peripheral portion 11 on which the label 2 is provided is located at the topmost position, so that the sheet body 1 can be unfolded by pinching and pulling this peripheral portion 11, and after wrapping an article, the second non-adhesive end portion 25 of the label 2 can be pinched again at the pinched peripheral portion 11 to peel off the label 2. This makes it easier to perform packaging work using the labeled packaging sheet while still providing it in a compact state.

[0022] In the configuration of the above embodiment, the first adhesive portion 21 of the label 2 adheres to one side of the sheet body 1, and the second adhesive portion 23 adheres to the opposite side, and the two do not adhere to each other. When the first and second adhesive portions 21 and 23 are long and the fold line portion of the middle non-adhesive portion 22 is located at a position quite far from the edge of the sheet body 1 (folded at a distant position), the first and second adhesive portions 21 and 23 may adhere to each other, but this embodiment excludes such a state. If the first and second adhesive portions 21 and 23 partially adhere to each other, they are not easily peeled off due to their high adhesive strength, and the workability of packaging deteriorates. In the configuration of the embodiment, the first and second adhesive portions 21 and 23 do not adhere to each other even partially, so there is no such problem. In addition, since the second non-adhesive end 25 is formed between the second adhesive portion 23 and the longitudinal edge of the second adhesive portion 23 on one side of the label 2, it is easy to pinch the second non-adhesive end 25 and peel the second adhesive portion 23 from the sheet body 1, which also makes the work easy.

[0023] In the configuration of the first embodiment, it is desirable that the fold line portion of the intermediate non-adhesive portion 22 contacts the edge of the sheet main body 1 or is located as close as possible to the edge. This point will be explained with reference to Fig. 6. Fig. 6 is a perspective schematic diagram showing the relationship between the fold line portion of the intermediate non-adhesive portion 22 and the edge of the sheet main body 1. In Fig. 6, the distance between the fold line of the intermediate non-adhesive portion 22 of the label 2 and the edge of the sheet body 1 is indicated by d. If d is long, the label 2 will protrude significantly from the edge of the sheet body 1. If the protrusion is too large, the label 2 will be easily bent or caught on something when packaging a large number of labeled packaging sheets, and in some cases the label 2 may be torn. Ideally, the distance d is 0 (the fold line is in contact with the edge), but even if there is a distance, the distance d is preferably 5 mm or less, and more preferably 3 mm or less, 2 mm or less, or 1 mm or less.

[0024] Next, a labeled packaging sheet according to a second embodiment will be described. Fig. 7 is a schematic perspective view of the labeled packaging sheet according to the second embodiment. In the labeled packaging sheet of the second embodiment, a label 2 is provided in a peripheral portion 11 of a sheet body 1. As shown in Fig. 7, in the second embodiment, the sheet body 1 is bag-shaped except for the peripheral portion 11 where the label 2 is provided. Hereinafter, the peripheral portion 11 of the sheet body 1 where the label 2 is provided is referred to as a lid portion, and the rest is referred to as a bag portion. A fold is formed at the boundary between the lid portion 11 and the bag portion 12.

[0025] In this embodiment, the label 2 is also folded in half at a fold line 221 in the intermediate non-adhesive portion 22, with the first adhesive portion 21 on one side adhering to one side of the peripheral portion 11 and the second adhesive portion 23 on the other side adhering to the opposite side of the peripheral portion 11, and the portion forming the valley of the intermediate non-adhesive portion 22 straddling the edge of the sheet body 1. The distance between the fold line 221 and the edge is 0 or a short distance of 5 mm or less. In addition, the second adhesive portion 23 has adhesive properties that allow it to be peeled off by hand and re-adhered.

[0026] When using the labeled packaging sheet of the second embodiment shown in Fig. 7, an article is placed in the bag portion 12, and the bag portion 12 is folded along the crease to bring the lid portion 11 close to the outer surface of the bag portion 12. The second non-adhesive end portion 25 is then pinched to pull up the label 2, and the second adhesive portion 23 is peeled off. The label 2 is then unfolded, and the second adhesive portion 23 is attached to the outer surface of the bag portion 12. This completes the packaging of the article. Even in this embodiment, there is no need to peel off the second adhesive portion 23 of the label 2 when placing an item in the bag portion 12, so the label 2 will not adhere to unintended locations when placing the item, making the packaging operation easy.

[0027] When producing the labeled packaging sheet of the second embodiment, a long and narrow rectangular (strip-shaped) sheet material is prepared and folded in two at a position slightly offset from the center in the length direction (the fold line is in the width direction). One end part protrudes slightly, and this part becomes the lid part 11. The folded sheet material is folded in two and both end parts are joined by heat sealing or the like to form the bag part 12. Thereafter, the label 2 having the above configuration is valley-folded at the middle non-adhesive part 22 and attached to the lid part 11 to complete the labeled packaging sheet of the second embodiment.

[0028] In each of the above embodiments, the label 2 has a shape that is curved inward and narrowed in width at the intermediate non-adhesive portion 22. Although a certain width is necessary to ensure sufficient adhesive strength at each of the adhesive portions 21, 23, such consideration is not necessary for the intermediate non-adhesive portion 22, and therefore the width is narrowed to reduce material costs. In addition, since a user may tear the intermediate non-adhesive portion 22 by hand to remove an article rather than peeling off the second adhesive portion 23, consideration has also been given to making the intermediate non-adhesive portion 22 relatively easy to tear.

[0029] In each of the above embodiments, the label 2 is symmetrical, and the first adhesive portion 21 has adhesive properties that allow it to be peeled off and re-adhesive by hand, so that in actual use, a person may pick up the first non-adhesive end 24 and peel off the first adhesive portion 21 to remove an article. However, in implementing the present invention, it is sufficient that either one of the adhesive portions is peelable and re-adhesive, and the end on that adhesive portion side is a non-adhesive end. However, if both adhesive portions are peelable by hand, this is preferable when peeling off and discarding the label 2 after use.

[0030] In addition to the above, the label 2 may have various shapes. Fig. 8 is a schematic plan view showing another shape of the label 2. Fig. 8 shows a shape of the label 2 that is asymmetric. Label 2 may have, for example, a rectangular shape with a small square protruding from the side as shown in FIG. 8(1), an oval shape with a small square protruding from the side as shown in FIG. 8(2), or a circle shape with a small square protruding from the side as shown in FIG. 8(3).

[0031] In Fig. 8 (1) to (3), the small rectangular portion corresponds to the second non-adhesive end portion 25. The large rectangular portion, elliptical portion, and circular portion are provided with the first adhesive portion 21, the middle non-adhesive portion 22, the second adhesive portion 23, and the first non-adhesive end portion 24, respectively. The shape of the label 2 in each example shown in Fig. 8 can be said to be a shape in which the second non-adhesive end portion 25 protrudes long and with a small width. That is, the width of the second non-adhesive portion 25 is narrower than that of the second adhesive portion 23, while the protruding length is longer than the width. This shape is significant in that it makes it easier to pinch the second non-adhesive portion 25 and makes it easier to peel off and re-adhere the second adhesive portion 23.

[0032] In addition, in the above explanation, cut Chinese cabbage was used as an example of the item to be packaged, but the labeled packaging sheet and labeled packaging sheet set of the present invention can also be used for other fresh food items such as other vegetables, fruits, meat, seafood, etc., and can also be used to package other foods and non-food items.
