Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container having a container body and a lid, and more particularly, to a container having an improved closure piece formed on the lid.

[0002]

[Prior art]

 As shown in FIGS. 8A and 8B, there is a container 1 in which the upper opening of the container body 2 is covered with a lid 3. The lid 3 is configured to be openable / closable with respect to the container body 2 by using an integrally formed connecting piece 4 (for example, Japanese Utility Model Publication No. 57-52015).

A sealing piece 5 is integrally formed on the lid 3 at a position facing the connecting piece 4, and when the container 1 is manufactured, the connecting piece 4 and the sealing piece 5 are bonded to the container body 2 with an adhesive 6. The lid 3 is opened by removing the adhesive state between the sealing piece 5 and the container body 2.

[0004]

[Problems to be solved by the device]

 However, in the case where the ruled line 8 is provided at the boundary between the front plate 7 of the lid 3 and the sealing piece 5, when the sealing piece 5 is pulled up by gripping the tip 5A of the sealing piece 5, the adhesive force of the adhesive 6 is increased. Is stronger than the sealing piece 5, so that delamination occurs in the sealing piece 5. As a result, the front surface side and the back surface side of the sealing piece 5 are separated, the back surface side of the sealing piece 5 remains adhered to the container body 2 through the adhesive 6, and only the front surface side of the sealing piece 5 is pulled up. I will be killed. Then, when the pulling force of the sealing piece 5 is increased by cutting the back surface side of the sealing piece 5 which is still adhered to the container body 2, the front plate 7 of the lid 3 and the both ends of the sealing piece 5 are increased. A break line 9 along it will result. However, when the sealing piece 5 is completely opened, the area of the back surface side of the sealing piece 5 adhered to the container body 2 becomes large, so that the sealing piece 5 of the container 1 cannot be peeled off cleanly.

In order to solve the above-mentioned problem, for example, when a discontinuous cut portion such as a perforation is provided over the entire boundary between the front plate 7 of the lid 3 and the sealing piece 5, the sealing piece is Although the 5 can be peeled off cleanly, the sealing piece 5 may be cut from the perforations in the manufacturing process of the container 1 or in the physical distribution. In other words, in the manufacturing process of the container 1, the sealing piece 5 is lifted when the adhesive 6 is spray-painted on the container body 2. At this time, the perforation portion becomes a fold and the perforation is cut. However, there is a possibility that vibrations during transportation on the flow of goods or stress when grasping the lid body and taking out this container from the storage box concentrate on the perforations and break.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a container capable of neatly peeling off the sealing piece of the lid without causing inconvenience during manufacturing. To do.

[0007]

[Means for Solving the Problems]

 According to the invention, in a container in which a lid is openably and closably attached to an opening of a container body, a connecting piece and a sealing piece formed on the lid are configured to be adhered to the container body with an adhesive. The sealing piece is formed with a cut portion having a size substantially equal to the adhesive coating width, on the side of the lid sealing piece in the pulling-up direction side of the adhesive application portion and not connected to the edge of the sealing piece. It was done.

[0008]

[Action]

 Therefore, according to the container body of the present invention, when the tip of the sealing piece is grasped to open the lid and the sealing piece is peeled off from the container body, the back side portion of the sealing piece is adhered by the adhesive. Since it is firmly adhered to the container body, delamination occurs in this sealing piece, the back side portion of the sealing piece remains adhered to the container body by the adhesive, and only the surface side portion of the sealing piece is pulled up. At this time, the sealing piece is formed with a cut portion having a size substantially equal to the adhesive application width on the side of the sealing piece in the pull-up direction with respect to the adhesive application portion. Blocked, the sealing piece separates from the backside part and is peeled off from the container body while the backside part is fixed to the container body. As a result, only the rear surface side of the sealing piece having a small area and a regular cut surface remains in the container body, so that the sealing piece of the lid can be peeled off cleanly.

Of course, since the cutting edge portion of the sealing piece is formed discontinuously on the side edge portion of the sealing piece, the sealing piece is cut at the portion having the cut portion even in the container manufacturing process and the like. It is possible to avoid inconvenience during manufacturing.

Next, regarding the elastomer adhesive 34A and the resin adhesive 34B, and the elastomer adhesive 35A and the resin adhesive 35B for adhering the connecting piece 31 and the sealing piece 32 to the container body 11, respectively. explain. These adhesives are thermoplastic hot melt type adhesives, and of these, the resin adhesives 34B and 35B are adhesives having a strong adhesive force at a high temperature, that is, at a room temperature of 20 ° C. or higher. Specifically, the resin adhesives 34B and 35B are adhesives made of polyethylene (PE), ethylene vinyl acetate copolymer (EVA), ethylene / ethyl acrylate copolymer (EEA), or the like.

Further, the elastomeric tacky adhesives 34A and 35A have a strong adhesive force at a low temperature, that is, in a temperature range from about −10 ° C. to room temperature (20 ° C.), and are adhesives rich in viscoelasticity. It Specific examples of the elastomer adhesives 34A and 35A include styrene / butadiene / styrene block polymerized elastomer (SBS), styrene / isoprene / styrene block polymerized elastomer (SIS), or styrene / ethylene / butylene. Examples thereof include styrene block polymerized elastomer (SEBS).

The resin adhesives 34 B and 35 B are applied to the positions of the container body 11 corresponding to the tip ends 42 and 43 of the connecting piece 31 and the sealing piece 32, respectively. Further, the elastomeric adhesive / adhesive agent 34A is applied to the position of the container body 11 corresponding to the hinge portion 36 side of the connecting piece 31, and the elastomeric adhesive / adhesive agent 35A is applied to the main cutting edge portion 39 side of the sealing piece 32. Is applied to the position of the container body 11 corresponding to. Then, as described above, the connecting piece 31 and the sealing piece 32 are pressed and adhered to the respective positions of the container body 11 to which the adhesive is applied. It should be noted that the adhesive-based adhesives 34A and 35A may be applied to the tip ends 42 and 43 of the connecting piece 31 and the sealing piece 32, respectively, and the resin-based adhesive 34A and 35A may be applied to the hinge portion 36 side of the connecting piece 31. The adhesive 34B may be applied to the main cutting edge portion 39 side of the sealing piece 32, and the resin adhesive 35B may be applied thereto.

According to the above-described embodiment, when the end portion 43 of the sealing piece 32 of the lid 12 is gripped and the sealing piece 32 is peeled off from the container body 11 in order to open the lid 12, as shown in FIG. As shown in (A), the back surface side portion 32b of the sealing piece 32 is firmly adhered to the half-cutting edge portion 41a of the adhesive application portion 38 of the container body 11 by the elastomeric adhesive 35A and the resin adhesive 35B. As a result, delamination occurs in the sealing piece 32, and the back surface side portion 32b of the sealing piece 32 remains in the adhered state on the adhesive application portion 38 of the container body 11 by the adhesives 35A and 35B. The front surface side portion 32a is pulled up. At this time, since the sealing piece 32 is formed with the main cutting edge portion 39 having a length L substantially equal to the adhesive coating width W, as shown in FIG. The sealing piece 32 is blocked by the main cutting edge portion 39, and is separated from the back surface side portion 32b while leaving the back surface side portion 32b in the half cutting blade portion 41a of the adhesive application portion 38 of the container body 11. It is peeled off from the main body 11. As a result, only a small area of the back surface 32b of the sealing piece having a cut section arranged by the main cutting edge 39 remains on the half-cutting edge 41a of the adhesive application part 38 of the container body 11, so that the lid 12 The sealing piece 32 can be peeled off cleanly.

Delamination of the sealing piece 32 occurs within the range of the adhesive application width W of the elastomeric adhesive 35A and the resin adhesive 35B shown in FIG. The width of the back surface side portion 32b is also substantially equal to the adhesive application width W. However, depending on the progress of delamination, the width of the back surface side portion 32b of the sealing piece 32 may be wider than the adhesive application width W. In this embodiment, since the sub cutting edge portion 40 is formed close to the main cutting edge portion 39, even if the width of the back surface side portion 32b is widened, the main cutting edge portion 39 and the sub cutting edge portion 40 are The back side portion 32 b can be cut by the portion 40. Therefore, also in this case, the back surface side portion 32b of the sealing piece 32 remaining in the container body 11 can be made to have a small area, and the end surface of the back surface side portion 32b can be the main cutting edge portion 39 and the sub cutting edge. Since the end face can be formed into a regular shape by the portion 40, the sealing piece 32 can be peeled off cleanly.

Furthermore, since the half-cutting blade portion 41a is formed in the adhesive application portion 38 of the container body 11 to which the sealing piece 32 is fixed, the sealing piece 32 of the lid 12 is formed as shown in FIG. 6B. After separating the container body 11 from the container body 11, as shown in FIG. 6C, if the back surface side portion 32b of the sealing piece 32 fixed to the adhesive application portion 38 is pulled, the adhesive force of the adhesives 35A and 35B can be reduced. By the action, the half-cutting blade portion 41a of the adhesive applying portion 38 of the container body 11 is peeled off from the container body 11. Therefore, the back surface side portion 32b of the sealing piece 32 can be easily removed from the container body 11 together with the adhesive application portion 38. However, since the half-cutting blade portion 41a of the adhesive-coated portion 38 is easily separated from the container body 11, the trace of the adhesive-coated portion 38 separated from the container body 11 is also clean.

It should be noted that the half-cutting blade portion 41b is provided from the container body 11 of the adhesive application portion 38 when the adhesive applied to the half-cutting blade portion 41a flows out above the half-cutting blade portion 41a when the sealing piece 32 is bonded. It is for cleaning the separation trace of. Further, with the above configuration, as shown in FIG. 6 (D), when the sealing piece 32 is pulled up, when the sealing piece 32 is not peeled between layers and the half-cutting edge portion 41a is peeled off. Can also clean the traces.

Further, since the main cutting edge portion 39 and the sub cutting edge portion 40 of the sealing piece 32 are formed discontinuously at the side edge portion of the sealing piece 32 at the boundary with the front side plate 22, the container 10 In the manufacturing process, the adhesives 35A and 35B are applied to the adhesive application section 38 of the container body 11 even if the sealing piece 32 is lifted at the time of application, or due to vibration generated during transportation of the container 10, Even when the lid 12 is gripped when the container 10 is taken out from the storage box, the sealing piece 32 is not cut at the boundary portion where the main cutting edge portion 39 and the sub cutting edge portion 40 exist, and thus, when the container is manufactured. There is no inconvenience.

Further, the connecting piece 31 and the sealing piece 32 of the lid 12 are composed of two kinds of adhesives, which have different adhesive strengths depending on temperature, such as an elastomer-based adhesive / adhesive agent 34A, a resin-based adhesive agent 34B, and an elastomer-based adhesive agent 35A. Since the resin adhesive 35B is used, the sealing piece 32 and the connecting piece 31 of the lid 12 do not peel off unnecessarily in the tropical region and the cold area, and the sealing piece 32 and the connecting piece 31 of the lid 12 do not peel off. Can be adhered and maintained in a wide temperature range.

Further, in the connecting piece 31, particularly, when the elastomer-based viscous adhesive 34A having a high viscoelasticity is applied to the hinge portion 36 side, the lid 12 is opened wide and the lid 12 of the lid 12 is opened. Even if the angle between the rear plate 23 and the connecting piece 31 becomes approximately 0 °, the elastomer adhesive 34A does not extend and the connecting piece 31 is not delaminated, preventing damage and separation of the connecting piece 31. can do. Therefore, the hinge performance of the connecting piece 31 can be improved.

Further, in the sealing piece 32, in particular, when the resin adhesive 35B is applied to the tip end 43 side, when the tip end 43 of the sealing piece 32 is gripped and pulled up, the sealing piece Delamination can be easily generated in 32. Therefore, the unsealing property of the sealing piece 32 can be improved.

In the above-mentioned embodiment, a description is given of using the double-strand-type elastomer adhesive / adhesive agent 34A and resin adhesive agent 34B to fix the connecting piece 31 to the adhesive agent applying portion 33 of the container body 11. However, the elastomer adhesive / adhesive agent 34A and the resin adhesive agent 34B may be combined and applied in three or more lines. In this case, in particular, in order to improve the hinge performance, the elastomeric tacky adhesive 34A may be applied to the hinge portion 36 side.

Further, as shown in FIGS. 7 (A) and 7 (C), the elastomer adhesive / adhesive agent 34A and the resin adhesive agent 34B are alternately applied on one row, and are applied to both sides of the connecting piece 31. The elastomer-based tacky adhesive 34A may be applied. Further, as shown in FIGS. 7 (B), (D) and (E), in the connecting piece 31, the elastomeric adhesive 34A is placed on the hinge part 36 side and the resin adhesive 34B is placed on the tip part 42 side. You may apply alternately. In the case of each of the coating patterns shown in FIGS. 7A to 7E, peeling of the connecting piece 31 can be prevented in a wide temperature range and the hinge performance can be improved, as in the above embodiment. . Further, in FIGS. 7B, 7D, and 7E, resin adhesive 34B is attached to the hinge side of the connecting piece 31 at the tip end, particularly when the adhesiveness in a wide temperature range is the main object. The elastomer-based tacky adhesive 34A may be applied to the 42 side.

The connecting piece 31 is adhered to the container body 11 only with the elastomer-based adhesive / adhesive agent 34A, and the viscoelasticity of the elastomer-based adhesive / adhesive agent 34A improves the hinge property of the connecting piece 31.
