Description

  The present invention relates to a container with a package.

  Conventionally, the shrink film is known as a package which decorates a container. In a container wrapped with a shrink film, water or a cleaning component diluted with water penetrates into a gap between the container and the shrink film, and there is a problem in terms of hygiene such as generation of mold. As a countermeasure, it is possible to physically avoid the intrusion of water etc. by applying a shrink film to the vicinity of the spout on the top side of the container and covering with a cap, but it is easy on the bottom side of the container. There is no simple means.

  Patent Document 1 and Patent Document 2 disclose a container having irregularities on the outer peripheral surface, and even when the outer peripheral surface is covered with a shrink film, a gap is generated between them, so that generation of mold or the like occurs. The effect which prevents can be expected.

  However, in Patent Document 1, although the purpose is to quickly drain water from between the reinforcing ribs extending obliquely, no measures are taken to prevent the entry of water or the like. Moreover, in patent document 2, since it aims at suppressing that a container will bend and deform | transform, it is not the structure which accelerates | stimulates discharge | emission of the water which permeated between shrink films. In Patent Document 3, it is possible to prevent water from entering from the bottom side by the folded bottom wall provided on the bottom side of the container, but the configuration is complicated.

Drawing 1 is a figure showing the schematic structure of the container with a package of a 1st embodiment.
As shown in FIG. 1, the packaged container 10 includes a bottle (container) 11 and a shrink film (package) 12 provided on the outer surface (outer peripheral wall) 11 a of the bottle 11. The shrink film 12 wound around the bottle 11 is heat-shrinked so as to be in close contact with the outer surface 11a of the bottle 11, thereby forming a part of the bottle shape.

  The bottle 11 is a container for storing a liquid material such as a liquid detergent, a liquid softening agent, a liquid bleaching agent, and the like. Also, the opening is formed to be quite thin and cylindrical. The mouth portion 11B is provided with a cap (not shown) that is detachable by screwing so that the opening of the mouth portion 11B can be opened and closed when in use or not in use.

  The trunk portion 11A has a circular or elliptical cross-sectional shape that intersects in the vertical direction, and has a shape in which the upper and lower shoulders are slightly narrowed in a side view. In the body portion 11A of the present embodiment, an annular convex portion (uneven structure) 11C is provided on the bottom side in the circumferential direction.

  The annular convex portion 11C protrudes outward from the outer surface 11a of the trunk portion 11A at a predetermined height, and the cross-sectional shape intersecting the circumferential direction is a semicircular shape. For this reason, the shrink film 12 which coat | covers the cyclic | annular convex part 11C is hard to be torn. The height from the outer surface 11a of the annular convex portion 11C and the size thereof are appropriately set.

  The bottle 11 is made of polypropylene (PP), polyethylene (PE), polyester (PET), or the like.

  The shrink film 12 is a heat-shrinkable resin film, and is composed of, for example, stretched polystyrene film (OPS), stretched polypropylene (OPP), stretched PET, or the like. The shrink film 12 is decorated with a pattern and characters such as a product name and product information, and is a design shrink film.

  The shrink film 12 covers (wraps) the outer surface 11 a of the bottle 11. The shrink film 12 in the present embodiment covers the trunk portion 11A of the bottle 11 including the annular convex portion 11C and a part of the neck portion 11D continuous to the trunk portion 11A, and the upper end 12a thereof is positioned in the middle of the neck portion 11D.

On the other hand, the lower end 12b of the shrink film 12 is located in the middle of the curved surface portion 11E without covering the bottom surface 11d of the bottle 11, and is provided so that the shrink film 12 is slightly separated from the placement surface when used.

  When the bottle 11 is packaged with the shrink film 12, the periphery of the body portion 11A of the bottle 11 is heat-shrinked by being covered with a heat-shrinkable film before heating, so as to follow the outer shape of the body portion 11A. This is done by deforming.

  At this time, a gap W that does not cause capillary action is formed between the shrink film 12 and the bottle 11 by the annular convex portion 11C provided in the circumferential direction on the bottom side of the bottle 11 (body portion 11A). The Specifically, the gap W is formed at least between the outer surface 11a around the annular convex portion 11C and the shrink film 12, and is preferably 1 mm or more.

  According to the packaged container 10 of the present embodiment, by providing the annular convex portion 11C on the bottom side of the bottle 11, between the outer surface 11a of the bottle 11 and the shrink film 12 covering the outer surface 11a. Even if moisture enters due to the capillary phenomenon, the capillary phenomenon is eliminated by the gap W, and further penetration can be prevented. In this embodiment, since the annular convex portion 11 </ b> C is continuously present in the circumferential direction of the bottle 11, it is possible to prevent moisture from entering from the bottom side in the entire circumferential direction of the bottle 11.

  Thereby, even if it is a case where the container 10 with a package is stored for a long time around water, such as a bathtub or a washroom, it can prevent that a water | moisture content enters between the bottle 11 and the shrink film 12. FIG. As a result, generation of mold can be effectively suppressed, and hygiene can be kept good.

  Conventionally, when the shrink film is provided on the bottle, the lower end of the shrink film is provided at a certain distance from the mounting surface so that the capillary phenomenon does not occur. However, in this embodiment, the shrink film 12 is provided. Even at the position where the lower end is close to the placement surface, the above-described gap W can suppress the intrusion of moisture due to the capillary phenomenon. Therefore, the display area can be increased and the design can be improved by the shrink film 12, which is advantageous in terms of advertisement and appearance.

  In the present embodiment, the annular protrusion 11C having a predetermined height is provided on the bottom side of the bottle 11 in the circumferential direction. However, the uneven structure provided in the bottle 11 is not limited to the above-described structure, and can be appropriately changed. Is possible. That is, it is only necessary to form a gap W that does not cause capillary action between the outer surface 11 a and the shrink film 12 on the bottom side of the bottle 11. By forming this gap W over the circumferential direction of the bottle 11, a higher antifungal effect can be obtained.

  In addition, in this embodiment, although it has the structure which provided only one cyclic | annular convex part 11C, you may provide multiple. Moreover, the shrink film 12 is provided so that the area | region containing 11 C of cyclic | annular convex parts of uneven structure among the trunk | drum 11A of the bottle 11 may be covered.

[Second Embodiment]
Next, the packaged container according to the second embodiment of the present invention will be described.
The basic configuration of the packaged container according to this embodiment shown below is substantially the same as that of the first embodiment, but is different in the concavo-convex structure (plural ridges). Therefore, in the following description, the concavo-convex structure will be described in detail, and description of common portions will be omitted. In the drawings used for the description, the same reference numerals are assigned to the same components as those in FIG.

FIG. 2 is a diagram illustrating an overall configuration of the packaged container according to the second embodiment.
As shown in FIG. 2, the packaged container 20 according to the present embodiment includes a bottle 21 having a plurality of ridges (convex portions) 21 </ b> C as a concavo-convex structure on the bottom side of the trunk portion 21 </ b> A.

  The plurality of ridge portions 21C are arranged at equal intervals over the circumferential direction of the trunk portion 21A. At this time, each protrusion 21C is a region between a pair of protrusions 21C, 21C adjacent in the circumferential direction, and a capillary phenomenon between the outer surface (outer peripheral wall) 21a of the bottle 21 and the shrink film 12. It is preferable that they are arranged at an interval that does not cause the problem.

  Each of the ridges 21 </ b> C extends linearly in one direction along the outer surface 21 a and is inclined at a predetermined angle θ with respect to the vertical direction of the bottle 21. In this way, by providing the respective ridges 21C to be inclined, the ridges 21C can be present in the circumferential direction of the bottle 21 as seen from the up and down direction (for example, the mouth 21B side) almost without interruption. It becomes possible.

As described above, the packaged container 20 according to the present embodiment has a configuration in which a plurality of ridge portions 21 </ b> C that are inclined with respect to the vertical direction of the bottle 21 are arranged at predetermined intervals in the circumferential direction of the bottle 21. . A gap W that does not cause capillary action is formed between the outer surface 21 a of the bottle 21 and the shrink film 12 by the plurality of protruding portions 21 </ b> C. In the present embodiment, since the plurality of ridges 21 </ b> C are inclined in the same direction, the gap W is formed so as to be continuous in the circumferential direction of the bottle 21.
According to such a configuration, similarly to the previous embodiment, it is possible to effectively prevent moisture from entering from the bottom side of the bottle 21 due to capillary action in the circumferential direction.

In addition, in the up-down direction of the bottle 21, a plurality of protruding ridges 21C may be provided so that the upper end side of one adjacent protruding ridge portion 21C and the lower end side of the other protruding ridge portion 21C partially overlap. (Overlapping region R indicated by hatching in FIG. 3). In this case, when viewed from the vertical direction, a function similar to the state in which the protruding strips 21 </ b> C continuously exist in the circumferential direction of the bottle 21 can be obtained, and the gap W can be formed in the circumferential direction of the bottle 21. it can.
According to this configuration, it is possible to more effectively prevent moisture from entering from the bottom side of the bottle 21 due to capillary action in the entire circumferential direction.

FIG. 4 shows a modification of the packaged container according to the second embodiment.
Like the container 25 with a package shown in FIG. 4, it is good also as a structure provided with multiple hemispherical convex part 26C as an uneven | corrugated structure in the bottom part side of the bottle 26 (torso part 26A). Here, the plurality of ridge portions 26 </ b> C are arranged so as to be different from each other in the vertical direction in the circumferential direction of the bottle 26.
Also in this configuration, a gap W that does not cause capillary action can be formed between the outer surface (outer peripheral wall) 26a around the ridge 26C and the shrink film 12.

[Third Embodiment]
Next, the packaged container according to the third embodiment of the present invention will be described.
The basic configuration of the packaged container according to this embodiment shown below is substantially the same as that of the first embodiment, but is different in the concavo-convex structure (grooves and a plurality of convex portions). Therefore, in the following description, the concavo-convex structure will be described in detail, and description of common portions will be omitted. In the drawings used for the description, the same reference numerals are assigned to the same components as those in FIG.

FIG. 5 shows a schematic configuration of the packaged container according to the third embodiment. FIG. 6 is a cross-sectional view showing a part of the concavo-convex structure.
A container 30 with a package shown in FIG. 5 includes a bottle 31 having a concavo-convex structure including a groove 31D and a plurality of convex portions 31C arranged in the groove 31D on the bottom side of the trunk portion 31A.

  The groove 31D is formed in an annular shape over the circumferential direction of the bottle 31, and is formed so as to be recessed from the outer surface (outer peripheral wall) 31a to the inside at a predetermined depth. The depth of the groove 31D is set to a depth that can prevent the heated resin film from entering the groove 31D and following the inner surface (outer peripheral wall) 31d in the packaging process. Here, the depth F of the groove 31D is a distance from the deepest portion P on the inner surface 31d to the outer surface 31a.

  The plurality of convex portions 31 </ b> C are provided at the center of the groove 31 </ b> D in the vertical direction, and are arranged at a predetermined interval in the circumferential direction. As shown in FIG. 6, the protrusion 31C protrudes from the inner surface (outer peripheral wall) 31d of the groove 31D at a predetermined height.

  As described above, the packaged container 30 of the present embodiment has a configuration in which a plurality of convex portions 31C are arranged in the groove 31D formed over the circumferential direction of the bottle 31. As a result, it is possible to effectively prevent the shrink film 12 from entering and adhering into the groove 31D, so that at least a gap W that does not cause capillary action is formed between the inner surface 31d of the groove 31D and the shrink film 12. Is done. The presence of this gap W makes it possible to prevent moisture from entering further upward.

  Thus, since the adhesiveness of a shrink film can be reduced by the some convex part 31C arrange | positioned in the groove | channel 31D, it can prevent that the shrink film 12 penetrates in the groove | channel 31D, and is torn.

  Here, although the height of the convex portion 31C is appropriately set, in the present embodiment, it is set to a height that does not protrude outward from the outer surface 31a. Thereby, it can prevent that the shrink film 12 tears by the convex part 31C in which a front-end | tip tends to become thin according to the dimension with the groove | channel 31D.

  In addition, although the convex part 31C may be formed at a height that protrudes outward from the outer surface 31a, it is necessary to have a dimensional shape that can prevent the shrink film 12 from being torn.

[Fourth Embodiment]
Next, the packaged container according to the fourth embodiment of the present invention will be described.
The basic configuration of the packaged container according to this embodiment shown below is substantially the same as that of the first embodiment, but is different in the concavo-convex structure (groove and discharge path). Therefore, in the following description, the concavo-convex structure will be described in detail, and description of common portions will be omitted. In the drawings used for the description, the same reference numerals are assigned to the same components as those in FIG.

FIG. 7 shows a schematic configuration of the packaged container according to the fourth embodiment.
A container with a packaging body 40 shown in FIG. 7 includes a bottle 41 having a concavo-convex structure including a corrugated groove 41D and a plurality of discharge passages 41E communicating with the groove 41D on the bottom side of the body 41A. Yes.

  The groove 41D is formed over the entire circumferential direction of the bottle 41, and is formed in a wavy shape by meandering in the vertical direction. The width of the groove 41D is constant as a whole, but may be partially different.

  The plurality of discharge paths 41 </ b> E extend linearly along the vertical direction, and are arranged at a predetermined interval in the circumferential direction of the bottle 41. Each discharge path 41E has one end communicating with the valley 42 of the groove 41D and the other end reaching the bottom surface 41d. The discharge path 41 </ b> E is formed with a width that does not cause capillary action with the shrink film 12. Also in the discharge path 41E, the width may be partially different in the extending direction, or the width may be gradually increased.

  The concavo-convex structure of this embodiment has a drainage function. If a large amount of water is applied to the packaged container 40 in a shower or the like, or water that has entered the groove 41D from the lower end of the shrink film is discharged. It is discharged to the outside through the path 41E. That is, since the groove 41D has a horizontal portion and is curved in a wave shape, the water that has entered the groove 41D flows through the inclined portion toward the valley portion 42 and naturally flows out from the discharge path 41E to the outside. . By connecting the discharge path 41E to all the valleys 42 in the groove 41D, it is possible to quickly discharge the water without retaining water in the groove 41D. Thereby, a hygienic state can be maintained for a long time.

  The concave-convex structure (for example, the groove shape) is not limited to the above-described structure, and other shapes may be used as long as the water accumulated in the groove 41D can be drained by its own weight. It is possible to add a drainage function to the concavo-convex structure by providing an inclined region in a groove formed in the circumferential direction of the bottle 41 and connecting a discharge path to the lower end side of the inclined region.

  Moreover, the depth of the groove | channel 41D and the discharge path 41E is the depth which can prevent that the heated resin film tracks along the inner surface (outer peripheral wall) of the groove | channel 41D and the discharge path 41E in a packaging process. Is set to Therefore, a gap W that does not cause capillary action is formed between the groove 41D and the discharge path 41E and the shrink film 12, so that moisture can be prevented from entering from the bottom side of the bottle 41 to the minimum. it can.

  As described above, the preferred embodiments according to the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the examples. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea described in the claims. It is understood that it belongs to.
