Advantages, configurations, and other objects of the present invention will become apparent from the following description of preferred embodiments of the present invention.

  Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

First embodiment (FIGS. 1 to 4)
The bottle shown in FIGS. 1 and 2 replaces a well-known PET bottle that has been widely used for delivering mineral water or tea, and is a plastic molded product. Although the capacity of the bottle 1 to which the present invention can be preferably applied is not particularly limited, the illustrated bottle 1 is a 2 liter container, and is typically used for delivering mineral water, but other uses. For example, it may be used for drinks, and is not limited to drinks, but may be used for shampoos and household detergents, for example.

  The basic shape of the bottle 1 is the same as the conventional one, and has a spout portion 3 (hidden by the cap and only a part of which is hidden in the drawing) covered with a screw cap 2 and a bottle body 4. The bottle body 4 has a cylindrical shape here, but is not particularly limited, and may have a prismatic shape such as a quadrangle or a pentagon.

  The spout portion 3 is an open end portion provided with a male screw for screwing the threaded cap 2 in order from the spout end toward the bottle body 4 (not shown in the drawing for reasons of drawing), circular It has a flange or neck ring 5, a neck portion 6 (FIGS. 2 and 3), and a shoulder portion 7. The configuration of the spout portion 3 is the same as that of the prior art.

  It is preferable that at least the opening end portion, the neck ring 5 and the neck portion 6 have the same degree of rigidity as the mouth portion of the conventional PET bottle. At least an upper end portion of the portion 7, that is, a boundary portion with the neck portion 6 may have substantially the same rigidity as the neck portion 6.

  The bottle body 4 is considerably thinner than a conventional PET bottle, and the thickness of the bottle body may be such that it is not easily deformed even if it is lightly pressed with a finger in an empty state. It may be a degree that is easily deformed. That is, the bottle body 4 is considerably thin compared to the conventional PET bottle, but may be thinned within a range capable of maintaining its own shape, and, like a pouch, It may be thinned to such an extent that it cannot hold its own shape.

  Incidentally, currently available PET bottles have a thickness of about 300 μm. As the bottle 1 to which the container holder of the present invention can be suitably applied, the thickness of the bottle main body 4 is less than 250 μm, preferably 200 μm or less, for example, a thickness of about 50 to 35 μm. It may be. If there is no problem in practicality while reducing the cost of the bottle 1, the thickness of the bottle 1 is not limited to a value of 10 μm units of 10 to 90, and it goes without saying that the thinner the better. .

  The cap 2 includes a non-open lid guarantee ring 11 that can be separated from the lower end of the cap 2 as in the prior art. The non-open lid guarantee ring 11 has a plurality of ratchet teeth (not shown) formed on the inner peripheral surface, and a plurality of teeth 12 that mesh with the ratchet teeth are formed at the boundary between the neck ring 5 and the open end portion. Yes. When the cap 2 is rotated, the unopened lid guarantee ring 11 is prohibited from being rotated by the ratchet teeth 12 and separated from the cap 2. Since the cap 2 provided with such an unopened guarantee ring 11 is conventionally known, further description thereof is omitted.

  Various types of modifications of the unopened guarantee ring 11 are known, for example, the unopened guarantee ring is broken. However, in the application of the present invention, the unopened guarantee ring 11 is limited to the illustrated unopened guarantee ring 11. Rather, it will be understood by those skilled in the art that it is applicable to any unopened guarantee ring. Therefore, in the following description, as a typical example, the description will be made in relation to the illustrated unopened guarantee ring 11, but this is merely an example and includes an explanation of any type of unopened guarantee ring. I want you to understand.

  The container holder 20 is typically a plastic molded product. Examples of plastic materials that can be used include polyethylene (PE), polypropylene (PP), ABS resin, polyamide (PA), polyacetal (POM), polyethylene terephthalate (PETP), and the like. At least a part of the container holder 20 can be made of metal.

  As can be understood from FIG. 4, the container holder 20 includes a pair of arms 21, 21 positioned so as to surround the bottle spout portion 3, and the pair of arms 21, 21 merge at one end thereof to be integrated. It has become. On the other hand, the other end, that is, the free end of the arm 21 is separated from each other to form a gap A (FIG. 4) in which the bottle spout portion 3 can be inserted between the other ends of the pair of arms 21 and 21. Yes.

  In this container holder 20, the arm 21 has an arc-shaped inner surface adapted to the bottle spout portion 3 having a circular cross section. The container holder 20 is fitted into the bottle spout part 3 through the gap A between the arms 21 and 21 with the elastic deformation of the pair of arms 21 and 21.

  Looking at the cross-sectional view shown in FIG. 4, there is a gap between the inner surface of the arm 21 and the outer peripheral surface of the spout part 3. As shown in FIG. 4, the container 21 is designed so that the arm 21 of the container holder 20 is in a loosely fitted state with a slight gap with respect to the bottle spout portion 3 with the container holder 20 attached to the bottle 1. Alternatively, the arm 21 and the bottle spout portion 3 may be designed to be in a close fitting state in pressure contact with each other.

  Moreover, although the inner surface shape of the arm 21 has the circular arc shape substantially corresponding to the diameter of the bottle spout part 3 in the example of illustration, it is not limited to this. You may have the circular arc shape of a larger diameter than the diameter of the bottle spout part 3. FIG. Further, the inner surface of the arm 21 may have an uneven shape such as a corrugated shape or a sawtooth shape when viewed in a horizontal section.

  Moreover, the arm 21 is provided with the inner surface which can contact | abut with the non-open lid guarantee ring 11, the neck ring 5, and the neck part 6 of the cap 2 in this Example. That is, the inner surface of the arm 21 has a substantially L-shaped vertical cross-sectional profile (see FIG. 3), but is not limited to this inner surface shape.

  The inner surface of the arm 21 may include an inner peripheral flange that can enter the gap between the neck ring 5 and the unopened lid guarantee ring 11. The arm 21 only needs to have a height dimension or an inner surface that engages with at least one of the unopened lid guarantee ring 11, the neck ring 5, the neck portion 6, and the shoulder portion 7 of the cap 2. Further, a skirt portion that can be engaged with at least the upper end portion of the bottle shoulder portion 7 may be attached to the lower end of the arm 21.

  Although not necessarily essential, the container holder 20 has a protruding piece, that is, a knob portion 22 that protrudes outward from the free end of the arm 21. Further, the container holder 20 is conveniently provided with a body portion 23 surrounding the periphery of the bottle body 4 along the outer shape thereof. The overall shape and the cross-sectional shape of the body portion 23 are arbitrary. That is, for example, the cylindrical bottle body 4 may have an arbitrary shape such as a rectangular cross section or a hexagonal cross section, and the body portion 23 may be in contact with the bottle main body 4, or There may be a slight gap.

  The trunk portion 23 has a shape that surrounds the substantially lower half of the bottle body 4 and has a shape in which the upper half of the bottle body 4 is opened. The bottle 1 can be inserted into the container holder 20 through the open portion obliquely above the trunk portion 23. In this case, in order to facilitate the insertion of the bottle 1, the width of the open portion may be widened or the height dimension of the body portion 23 may be set small.

  The trunk | drum 23 of the container holder 20 has a shape open | released below. That is, the container holder 20 does not include a bottom portion that receives the bottom of the bottle 1. Therefore, it can be inserted into the bottle 1 from below the container holder 20. In this case, for example, the lower end portion of the container holder 20, that is, the lower end portion of the body portion 23, may be configured to expand downward. Due to the guiding action of the expanded portion, that is, the tapered portion, the bottle 1 can be easily inserted from below the trunk portion 23.

  The body portion 23 has two pairs of vertical slits 24, and the bottles 1 can be handled by using the pairs of vertical slits 24. For example, the bottle 1 can be tilted and the mineral water can be poured into a cup. it can.

  The body portion 23 and the pair of arms 21 and 21 are connected by a connecting portion 25 that extends vertically along the bottle 1. That is, the connecting portion 25 has a shape that extends in the horizontal direction from the joining portion of the pair of arms 21 and 21 and then hangs down substantially at a right angle to join the body portion 23.

  In other words, the connecting portion 25 has an inverted L shape when viewed from the side, and the corner portion 27 of the connecting portion 25 is suitable for lifting the bottle 1 by placing a finger thereon. For example, when the bottle 1 is stood and stored in the pocket of the door of the refrigerator, the bottle 1 can be taken out from the refrigerator by placing a finger on the corner portion 27 of the connecting portion 25 of the container holder 20.

  As shown in FIG. 2, the container holder 20 shown in the figure has a shape obtained by dividing a cylindrical shape by a single vertical slit, as can be best understood from FIG. That is, the trunk portion 23 has a pair of substantially semicircular side walls 26 that surround the substantially lower half of the bottle body 4 from the portion where it joins the connecting portion 25 and from the left and right, respectively. A gap is formed between the free end edges facing each other, and the pair of side walls 26, 26 are formed with the pair of vertical slits 24 in the vicinity of the free end edges facing each other. Another pair of vertical slits 24 is formed along the extended line of the base end portion, that is, the connecting portion 25 (one vertical slit does not appear in the drawing because of the illustration). That is, one pair of vertical slits 24 and the other pair of vertical slits 24 are arranged to face each other in the diametrical direction, and the user inserts a finger into any pair of vertical slits 24 to hold the container holder 20. The inside bottle 1 can be handled.

  If necessary, the container holder 20 narrows the distance between the pair of arms 21 and 21 so that the pair of knobs 22 is picked with the fingers F (FIG. 4) of one hand, if necessary. It is preferable to rotate the cap 2 while applying a moderate force. As a result, the cap 2 is opened, that is, the cap 2 is separated from the unopened guarantee ring 11 while the pair of arms 21 and 21 are pressed against the spout portion 3 to prevent the bottle 1 from being rotated by frictional engagement. it can.

  The container holder 20 may be configured by omitting the knob portion, that is, the protruding piece 22. In the case of the container holder 20 that does not include the protruding piece 22, the container holder 20 is attached to the bottle 1. The pair of arms 21 and 21 may be in a state of being closely fitted to the bottle spout portion 3.

  The user presses the pair of arms 21, 21 from the outside with the fingers of one hand or rotates the cap 2 while pressing the other part of the container holder 20 with the hand, whereby the container holder 20, that is, the pair of arms 21. The cap 2 can be opened while preventing the bottle 1 from rotating due to anti-slipping by frictional engagement between the bottle 21 and the bottle spout 3.

  In the following, other embodiments according to the present invention will be described. However, the same elements as those of the bottle 1 and the first embodiment described above are denoted by the same reference numerals, and the description thereof will be omitted. The characteristic part of will be described.

Second embodiment (FIGS. 5 to 8)
In the description of the second embodiment, a case where a notch or a recess 31 is formed in the neck ring 5 in the bottle 1 will be described as an example. The neck ring 5 is formed with a pair of recesses 31 opposed in the diameter direction. The recess 31 is preferably rectangular.

  In the container holder 30 of the second embodiment, protrusions 32 are formed on the inner surfaces of the pair of arms 21 and 21, respectively. The protrusion 32 may have a rectangular shape that meshes with the recess 31. The positions of the protrusions 32 are positions that can be engaged with the pair of recesses 31 of the neck ring 5 when the container holder 30 is attached to the bottle 1, that is, positions that are separated by 180 degrees around the circumference of the neck ring 5. Is arranged.

  When the container holder 30 is attached to the bottle 1, the protrusion 32 of the pair of arms 21, 21 and the recess 31 of the neck ring 5 are in an unevenly engaged state and mechanically engaged to form a slip stopper. For this reason, when the cap 2 is removed, the bottle holder 1 can be prevented from being rotated by supporting the container holder 30 by hand.

  In this container holder 30, when the pair of arms 21, 21 is attached to the bottle spout portion 3, the inner surface of the arm 21, particularly the state where the protrusion 32 is in pressure contact with the bottle spout portion 3, It is preferable to design so that it becomes.
