  The present invention relates to a container with an attached part to which an attached part such as a straw is attached via an adhesive.

2. Description of the Related Art Conventionally, a container having a container main body made of a synthetic resin molded product and a heat shrinkable sheet made of a synthetic resin mounted on the body of the container has been known as a container for drinking or food.
In patent document 1, the bag which accommodated the straw as an attachment part is attached to the outer surface of the above containers by heat sealing | fusion.
Moreover, an attachment part may be attached to the outer surface of the said container through a hot-melt-adhesive agent.
Usually, a hot melt adhesive is partly attached to the outer surface of a container corresponding to one place of the attached part or two places at predetermined intervals, and the attached part is attached thereto.

However, a sheet made of synthetic resin is attached to the outer surface of the container, and a hot melt adhesive is attached to the outer surface of the sheet, so that the adhesive force between the hot melt adhesive and the outer surface of the container is not sufficient, and hot The interface between the melt adhesive and the sheet may peel off.
When the hot melt adhesive is peeled off in this way, the attached part falls off from the container, and thus an improvement is required.

Japanese Utility Model Publication No. 62-31419

  An object of the present invention is to provide a container with an attached part that is difficult to come off an attached part attached to the container via a hot melt adhesive.

  The container with an attached part of the present invention has a container body, a sheet attached to the body part of the container body, and an attached part attached via a hot melt adhesive attached to the outer surface of the sheet. A small hole is formed in the sheet, and the hot melt adhesive is attached to the outer surface of the sheet including the small hole.

  In the container with an attached portion of the present invention, the hot melt adhesive is attached to the outer surface of the sheet including the small holes, so that the hot melt adhesive can enter the small holes and be cured. Since the cured hot melt adhesive engages with the small holes, the hot melt adhesive is hardly peeled off from the outer surface of the sheet. Therefore, the attached portion attached to the outer surface of the sheet via the hot melt adhesive is difficult to come off.

In a preferred container with an attached portion of the present invention, the peripheral edge of the small hole is raised outward.
When the peripheral edge of the small hole (the sheet portion at the peripheral edge of the small hole) is raised outward in this manner, the hot melt adhesive after curing is engaged with the portion, so that the hot melt adhesive is removed from the outer surface of the sheet. It becomes harder to peel off.

  ADVANTAGE OF THE INVENTION According to this invention, the container with an attached part which an attached part cannot remove easily can be provided. If such a container with an attached part is used, the attached part can be prevented from falling off during transportation or display.

Examples of the container body 5 include a synthetic resin molded product, a metal molded product, a glass molded product, and a ceramic molded product.
The shape of the container body 5 is not particularly limited, and may be a substantially cup shape with an upper surface opening type as illustrated, a substantially cylindrical shape with an upper surface opening type, a substantially bottle shape, or the like.

A lid member is attached to the container body 5. In the example of illustration, the sheet | seat cover 4 is attached to the flange part of the container main body 5 with the heat seal so that the upper surface opening of the container main body 5 may be covered.
The filling material put in the container body 5 is not particularly limited. Examples of the filling include foods to be chilled such as frozen desserts and cold beverages, foods to be warmed and eaten such as ramen and hot beverages, sanitary products such as shampoos, cosmetics, pharmaceuticals, toys, and machine parts.

A sheet 6 is mounted on the outer surface of the body 51 of the container body 5.
The sheet 6 has heat shrinkability. The heat shrinkability refers to the property that when heated to a predetermined temperature (for example, 100 ° C.), it can heat shrink by 20% or more in the left-right direction (the circumferential direction of the container body 5 when attached to the container body 5). .
The sheet 6 is formed in the form of a cylindrical label by rolling the sheet 6 and overlapping both end portions thereof, and pasting the overlapping portions with a solvent or an adhesive.
The sheet 6 formed in a cylindrical shape is fitted on the outer side of the body part 51 of the container body 5, and then heated to a predetermined temperature to thermally contract the sheet 6, thereby forming a sheet on the outer surface of the body part 51 of the container body 5. 6 is installed.

The type of the sheet 6 is not particularly limited, and examples thereof include a synthetic resin sheet, a foamed resin sheet, a nonwoven fabric and a laminated sheet thereof, and a laminated sheet of these and a functional layer.
The materials of the synthetic resin sheet, the foamed resin sheet and the nonwoven fabric are not particularly limited. For example, olefin resin such as polypropylene, polyester resin such as polyethylene terephthalate, styrene resin such as polystyrene, cyclic olefin resin, vinyl chloride 1 type chosen from thermoplastic resins, such as resin, or a 2 or more types of mixture etc. are mentioned.
Examples of the laminated sheet include a laminate of a synthetic resin sheet and a foamed resin sheet, and a laminate of a synthetic resin sheet and a nonwoven fabric. Examples of the functional layer include a barrier layer that blocks gas and / or light.

The sheet 6 is printed with a desired design such as a trade name and a design. Further, an adhesive layer (not shown) for adhering to the outer surface of the container body 5 may be provided on the inner surface of the sheet 6. By providing the adhesive layer, it is possible to reliably prevent the mounted sheet 6 from being displaced with respect to the container body 5.
The adhesive layer may be provided in a solid shape on substantially the entire inner surface of the sheet 6 or may be provided on a part of the inner surface of the sheet 6. The adhesive layer can be provided, for example, by applying a heat-sensitive adhesive to the entire inner surface of the sheet 6 or partially.

The sheet 6 to be used is preferably a synthetic resin sheet (including a multilayer synthetic resin sheet in which two or more synthetic resin sheets are laminated) or a laminated sheet including a synthetic resin sheet, and more preferably a synthetic resin. A sheet or a laminated sheet in which a synthetic resin sheet and a foamed resin sheet or a nonwoven fabric are laminated. By using a foamed resin sheet or a sheet having a non-woven fabric, a container having excellent heat insulation can be configured.
Moreover, although the thickness of the said synthetic resin sheet is not specifically limited, Usually, they are 30 micrometers-100 micrometers. Although the thickness of the said lamination sheet is not specifically limited, Usually, they are 50 micrometers-300 micrometers.

  Small holes 7 are formed in the surface of the sheet 6. The position where the small hole 7 is formed is appropriately set according to the position where the attachment portion 3 is attached (the position where the hot melt adhesive 8 is attached). In the present embodiment, as shown in FIG. 1, two hot melt adhesives 8 are attached at predetermined intervals in the longitudinal direction of the container body 5. Small holes 7 are formed in two places on the upper and lower sides of the sheet 6 so as to correspond to the attachment position of the hot melt adhesive 8. Although only one small hole 7 may be provided per location, a plurality of small holes 7 are preferably formed.

  For example, a plurality of small holes 7 are intermittently connected in the vertical direction of the sheet 6 (the vertical direction of the container body 5 when mounted on the container body 5) and / or in the left-right direction (see FIG. 4). FIG. 4 is a front view of the container 2 (with the sheet 6 attached to the container body 5) to which the attached portion 3 is not attached. FIG. 4 illustrates a case where the plurality of small holes 7 are formed intermittently in the vertical direction and the horizontal direction of the sheet 6. Moreover, the dashed-two dotted line of FIG. 4 has shown an example of the attachment area | region of the hot-melt-adhesive 8. FIG.

When a plurality of small holes 7 are formed in one place, the interval between adjacent small holes 7 is not particularly limited, but is preferably 0.5 mm to 2 mm. In addition, the said space | interval means the center distance of the small hole 7 adjacent to an up-down direction and a left-right direction.
Examples of the shape of one small hole 7 include a substantially circular shape, a substantially elliptical shape, and an elongated linear shape when viewed from the front, and are preferably a substantially circular shape or a substantially elliptical shape. The size of one small hole 7 is not particularly limited, but if it is too small or large, the effects of the present invention may not be sufficiently exhibited. For this reason, the size of one small hole 7 is preferably 0.3 mm to 2 mm.
However, the size of the small hole 7 means the maximum diameter of the small hole 7 when the sheet 6 is attached to the container body 5.

  Moreover, as shown in FIG. 3, it is preferable that the peripheral part 61 (outer surface part of the sheet | seat 6 in the periphery of the small hole 7) of the small hole 7 is rising outside. When the peripheral edge 61 of the small hole 7 is raised outward in this manner, the cured hot melt adhesive 8 is engaged with the portion 61, so that the hot melt adhesive 8 is more difficult to peel off from the outer surface of the sheet 6. Become.

For example, with respect to the sheet 6 before being attached to the container body 5, by forming a small hole 7 by piercing the sheet 6 with a perforating needle from the inner surface side toward the outer surface side, the peripheral edge 61 of the small hole 7 is moved outward. A raised sheet 6 can be obtained. The sheet 6 is mounted on the container body 5 with the inner surface side of the sheet 6 facing the outer surface of the container body 5. Further, even when laser irradiation is used instead of the perforating needle, the sheet 6 in which the peripheral edge 61 of the small hole 7 rises outward can be obtained.
When the sheet 6 in which the peripheral edge 61 of the small hole 7 swells in this way is heat-shrinked for mounting on the container body 5, the swelled part 61 contracts and curls (the curled state is not good). (Illustrated). Therefore, in particular, the cured hot melt adhesive 8 is easily engaged with the portion 61.

The hot melt adhesive 8 is an adhesive that is not adhesive at room temperature but can be bonded by heating. The hot melt adhesive 8 can be applied by heating and melting itself. Examples of the hot melt adhesive 8 include those in which an additive such as a tackifier is blended in the base resin.
Examples of the base resin include ethylene resins such as an ethylene-vinyl acetate copolymer and an ethylene acrylic acid copolymer, and a styrene-butadiene block copolymer. Examples of the tackifier include rosin resin, terpene resin, petroleum resin, phenol resin and the like.

The hot melt adhesive 8 is attached to the outer surface of the sheet 6 so as to cover the small holes 7. In the case where a plurality of small holes 7 are formed in one place, the hot melt adhesive 8 may be attached including all of the small holes 7 or a part of the small holes 7 may be included in the hot melt. An adhesive 8 may be attached. That is, the hot melt adhesive 8 may be attached to the outer surface of the sheet 6 including at least one small hole 7. In particular, it is preferable that the hot melt adhesive 8 is attached including the small hole 7 in which the peripheral edge portion 61 is raised outward.
The hot-melt adhesive 8 that has been heated and melted and applied to the outer surface of the sheet 6 enters the small holes 7 and adheres to the periphery 61 of the raised small holes 7. Accordingly, the cured hot-melt adhesive 8 engages with the small holes 7 and the protruding peripheral edge 61.

The attachment portion 3 is bonded to the hot melt adhesive 8 attached (adhered) to the outer surface of the sheet 6. Therefore, the attachment part 3 is attached to the outer surface of the sheet 6 (container 2) via the hot melt adhesive 8.
The annex 3 is not particularly limited. As typical attachment part 3, the thing (for example, a straw, a spoon, chopsticks, etc.) provided for the filling in the container main body 5 and a sales promotion product (a bonus etc.) are mentioned. . Although these articles may be directly bonded to the hot melt adhesive 8, these articles are usually stored in a bag and the bag is bonded to the hot melt adhesive 8. In the illustrated example of FIG. 3, the attachment portion 3 is composed of an elongated small bag 31 and a straw 32 (article) housed in the bag 31, and the outer surface of the bag 31 is affixed to the hot melt adhesive 8.

  In addition, the attachment part 3 is not limited to the case where the above-described article is included, and may be, for example, a storage bag or a storage box for storing an object for a user. Such a storage bag or the like does not previously store an article such as a bonus, but the storage bag or the like is used for a purpose such as a user putting and storing an arbitrary article in the storage bag.

  In the container 1 with an attached portion of the present invention, since the hot melt adhesive 8 is engaged with the small hole 7 and the peripheral edge portion 61 thereof, it is difficult to peel off from the outer surface of the sheet 6. Accordingly, it is difficult to remove the attached portion 3 attached to the outer surface of the sheet 6 via the hot melt adhesive 8. According to the container 1 with an attached part of the present invention, the attached part 3 can be prevented from falling off during transportation or display.

Next, the modification of this invention is shown. Hereinafter, parts different from those of the above-described embodiment will be mainly described. For the same configuration, terms and drawing numbers are used, and description thereof is omitted.
In the above embodiment, the sheet 6 is formed in a cylindrical shape in advance. However, the sheet 6 is wrapped around the container body 5 by winding the substantially rectangular (or substantially fan-shaped) sheet 6 around the outer surface of the body 51 of the container body 5. It may be attached. In this case, a sheet having no heat shrinkability may be used as the sheet 6, but it is preferable to use a sheet having heat shrinkability because it can be mounted neatly by being heated after being wound.

  Furthermore, in the said embodiment, although the sheet | seat 6 is mounted | worn to the whole vertical direction of the trunk | drum 51 of the container main body 5, it is not restricted to this, For example, a sheet | seat is only in the longitudinal direction middle region of the trunk | drum 51 of the container main body 5. 6 may be attached. Moreover, in the said embodiment, although the sheet | seat 6 is mounted | worn to the whole circumferential direction of the trunk | drum 51 of the container main body 5, it is not restricted to this, For example, the sheet | seat 6 is attached to the circumferential direction part of the trunk | drum 51 of the container main body 5.
