Description

  The present invention relates to a handle tape used when a water bottle is installed in a water server.

  With the recent increase in health consciousness, tap water tends to be avoided in urban areas, and water servers are spreading not only in hospitals and offices but also in general households. The user needs to perform the work of installing the water bottle in this water server. Usually, the user holds the handle and lifts the water bottle with the mouth facing downward, and inserts the mouth into the insertion port on the server side. I do.

  This water bottle is mainly made of polycarbonate with excellent strength, but it takes time to crush when discarding, and when the water bottle water is supplied to the server side, the atmospheric pressure inside the water bottle is maintained. Therefore, it was necessary to send air into the water bottle. Moreover, although what used the hard resin shape | molded also was used for the handle, the problem that the manufacturing process which integrates a handle with a water bottle requires an effort and cost also arose.

  In response to this, the replacement of hard water bottles with soft water bottles is progressing, which makes it easy to crush at the time of disposal, and when the remaining amount of water decreases, the water bottle naturally becomes atmospheric at atmospheric pressure. Because it is crushed, it is no longer necessary to send air into the water bottle.

  Since this soft water bottle is discarded after a single use in principle, it is an indispensable requirement to reduce the manufacturing cost, and the same applies to the handle provided in the water bottle. As an example of the handle provided in the soft water bottle, the handle described in Patent Document 1 below can be cited. This handle consists of a belt-like body stuck so as to cross the bottom of the water bottle, and is used by sticking both ends to both ends of the bottom of the water bottle.

  However, water bottles used in water servers are mainly 12 liters in full water and 10 kg or more in weight, and the handle described in Patent Document 1 lacks load resistance and durability, and is used multiple times. It could not withstand use.

  Accordingly, a handle in which glass fiber is embedded in an adhesive layer constituting the handle has been proposed in order to enhance load resistance and durability. However, this increases the load resistance and durability, but the handle must be peeled off when the water bottle is recycled, and the glass fiber is embedded in the adhesive layer of the handle that forms the adhesive surface with the water bottle. In the configuration, a problem that glass fibers remain on the water bottle side newly arises.

  The problem to be solved by the present invention is a handle having excellent load resistance and durability, can be peeled off from the water bottle without leaving glass fiber on the water bottle side, and is excellent in terms of post-processing at the time of recycling. To provide a tape.

  The present invention has been made to solve the above-mentioned problems, and the handle tape according to claim 1 is a handle tape used by being affixed to a water bottle for a water server, and is a first PET made of polyethylene terephthalate. A first adhesive layer made of an adhesive applied on the surface of the first PET layer, a glass fiber layer disposed on the surface of the first adhesive layer, and the glass fiber A second adhesive layer composed of an adhesive applied on the surface of the layer, and a second PET layer composed of polyethylene terephthalate disposed on the surface of the second adhesive layer, An adhesive layer is formed on one side of the laminated PET film using a strip-like laminated PET film in which the first PET layer and the second PET layer are bonded with an adhesive across the glass fiber layer as a base material. To form the adhesive portion to the both ends in the longitudinal direction are provided, characterized in that the formation of the non-adhesive portion in the longitudinal middle portion sandwiched between the adhesive portion.

  The handle tape according to claim 2 is characterized in that, in the handle tape according to claim 1, the non-adhesive portion is formed by attaching a cover sheet made of a nonwoven fabric to the central portion.

  The handle tape according to claim 3 is the handle tape according to claim 2, wherein the laminated PET film has transparency and the cover sheet has a printing ink layer on a surface to be bonded to the laminated PET film. It is characterized by that.

  According to the handle tape of claim 1 of the present invention, the glass fiber is embedded between the two layers of PET, thereby providing high strength load resistance and durability and without leaving the glass fiber on the water bottle side. It can be peeled off from the water bottle and can provide a handle tape that is excellent in terms of post-processing during recycling.

  Moreover, according to the handle tape of Claim 2 of this invention, since an adhesive agent is apply | coated to the single side | surface whole surface of a laminated PET film, a manufacturing process can be simplified and it is suitable for continuous processing. Moreover, since the cover sheet which consists of a nonwoven fabric is further laminated | stacked on the lamination | stacking PET film used as a base material, load resistance and durability are strengthened by that much.

  Moreover, according to the handle tape according to claim 3 of the present invention, precautions and advertisements at the time of disposal printed on the cover sheet can be visually recognized through the laminated PET film, so that information can be transmitted to the user. Figured.

It is a figure which shows the use condition of the handle tape of this invention. It is a top view of the handle tape of the present invention. It is a perspective view which shows the handle tape of this invention. It is the fragmentary sectional view which followed the AA line of FIG. 2 which cut | disconnected the handle tape of this invention in the longitudinal direction. It is a perspective view which shows the multilayer body for handle tapes.

  Hereinafter, a handle tape according to an embodiment of the present invention will be described with reference to the drawings.

  The handle tape 1 of the present invention is a belt-like body that is used to suspend a water bottle 2 with its mouth facing downward when the water bottle 2 is installed in a water server. It attaches to the water bottle 2 by making it surface-bond and fix, and making the other edge part surface-bond to the cylinder part which opposes so that the bottom part of the water bottle 2 may be straddled. Between the handle tape 1 and the bottom of the water bottle 2, a space enough to insert a hand is secured. The water bottle 2 is formed of a flexible material such as polyethylene terephthalate resin or polyethylene resin so that the water bottle 2 is naturally crushed by the atmospheric pressure when the remaining amount of water in the interior is reduced.

  2 to 4 show details of the handle tape 1 of the present invention. The handle tape 1 is made of a PET layer 3 made of polyethylene terephthalate and an adhesive made of an adhesive applied on the surface (lower surface) of the PET layer 3. An adhesive layer 52 composed of a layer 51, a glass fiber layer 4 disposed on the surface (lower surface) of the adhesive layer 51, an adhesive applied on the surface (lower surface) of the glass fiber layer 4, and an adhesive layer And PET layer 6 made of polyethylene terephthalate disposed on the surface (lower surface) of 52, and PET layer 3 and PET layer 6 are adhered by adhesive layers 51 and 52 on both sides of glass fiber layer 4. Using the laminated PET film 10 as a base material, an adhesive layer 7 is provided on one side (lower surface) of the laminated PET film 10 to form adhesive portions 8 and 8 at both ends in the longitudinal direction, and a nonwoven fabric is formed at the center in the longitudinal direction. Cover Formed by attaching a door 9.

  In addition to flexibility and electrical insulation, the laminated PET film 10 that is the base material of the handle tape 1 has a film-forming function in addition to performance such as heat resistance, various mechanical strengths, chemical resistance, and solvent resistance. The outer shape is based on PET layers 3 and 6 obtained by molding a polyethylene terephthalate resin excellent in ease and economy into a strip shape.

  The dimensions of the handle tape 1, that is, the PET layers 3 and 6, in the longitudinal direction and the width direction are selected based on the shape (size) of the water bottle 2 and the weight of the stored water. Taking the water bottle for 12 liters, which is the mainstream among water bottles currently used in water servers, as an example, the PET layers 3 and 6 have a longitudinal dimension of 390 to 400 mm and a width dimension of 25 mm. It is preferable to set to.

  The glass fiber layer 4 may be composed of a woven fabric woven using a bundle of fibers (single yarn) for warp and weft, or a nonwoven fabric randomly or unidirectionally deposited.

  The first and second adhesive layers 51 and 52 are constituted by an adhesive applied on the surface of the PET layer 3 and an adhesive applied on the surface of the glass fiber layer 4. A part of the applied adhesive is impregnated in a region where the warp and the weft of the glass fiber layer 4 are not present to enhance the adhesive force. As the adhesive, for example, a rubber-based, acrylic-based, silicone-based, epoxy-based, or polyimide-based resin material can be used. The form of the adhesive is roughly classified into a solvent type and a solventless type. For example, when using a solvent type, the adhesive is applied on the surface of the PET layer 3 and the glass fiber layer 4 in a state where the adhesive is dissolved in the solvent, The adhesive layers 51 and 52 are formed by drying.

  The PET layer 3 and the PET layer 6 are attached in such a manner that the glass fiber layer 4 is held inside by the adhesive constituting the adhesive layers 51 and 52 and the adhesive impregnated in the glass fiber layer 4. Thereby, the laminated PET film 10 having a high strength load resistance and durability is obtained.

  The laminated PET film 10 has an adhesive layer 7 provided on the entire surface of one side, adhesive portions 8 are formed at both ends in the longitudinal direction, and a cover sheet 9 is attached to an intermediate portion in the longitudinal direction excluding the adhesive portions 8. A paste killing process is applied. This prevents the handle tape 1 from sticking to the bottom of the water bottle 2 or sticking the hand holding the handle tape 1 especially when the water bottle 2 is placed on the floor. Can do.

  In this regard, as means for providing the adhesive portion 8 and the non-adhesive portion 9 on one side of the laminated PET film 10, a means for providing an adhesive layer only at both ends in the longitudinal direction of one side of the laminated PET film 10 may be employed. However, as in this embodiment, it is preferable to provide the adhesive layer 7 on the entire surface of the laminated PET film 10 to simplify the manufacturing process and is suitable for continuous processing. The advantage that the load resistance / durability is enhanced is more preferable.

  The cover sheet 9 of the present embodiment is made of a nonwoven fabric, and a printing ink layer 20 is provided on the surface to be bonded to the laminated PET film 10. On the printing ink layer 20, for example, precautions at the time of disposal, advertisement texts, and the like are printed, and thereby information transmission to the user is achieved. By providing the printing ink layer 20 on the surface to be bonded to the laminated PET film 10, there is no possibility that the printing ink is peeled off.

  The handle tape of the present invention can be manufactured one by one according to the state of use and placed in circulation. For example, the laminated PET film 10 and the cover sheet 9 are stacked in multiple stages, and the release paper is stacked in the lowermost stage. It is preferable to produce a multi-layer body for the handle tape (FIG. 5) because the production efficiency is improved and the cost can be suppressed. Moreover, when putting it in circulation, a large number of, for example, 25 handle tapes can be stacked in the thickness direction to form one bundle, and if the release paper 30 is attached to the bottom, it can be distributed. Also suitable for convenience.
