Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin bottle capable of suppressing the removal of carbonated drinking water, carbon dioxide such as beer, etc. remaining in the resin bottle.

[Prior Art] Plastic bottles for storing beverages such as PET bottles are capped again with a lid as a gas release measure when there is carbonated drinking water or beer remaining in each bottle. It just stopped.

[Problems to be Solved by the Invention] In many cases, a large bottle of carbonated drinking water or beer opened for consumers cannot be drunk at once. If you drink only a portion of carbonated drinking water or beer in a large bottle and store the rest, in the conventional bottle, even if there is a space in the bottle due to the reduced amount of beverage, Due to this space, there is a drawback that the carbonated drinking water or beer loses carbonic acid over time.

[Means for Solving the Problem] In order to solve this problem, the present inventor has conducted extensive studies, and as a result of earnest research,
The present invention has been completed. That is, at least one accordion-shaped or spiral-shaped contraction section (2) that can be expanded and contracted in the vertical direction is provided in place of part or all of the side surface of the resin bottle body (1), and the upper part of the contraction section. And a means for adjusting and fixing the displacement of the shrinking portion in the shrinking direction is provided in the non-shrinking portion (3) adjacent to the lower part, and specifically, the adjusting means can attach and detach the adjusting means to the resin bottle. Has at least one fixing means, and one end or a part of the intermediate portion of the adjusting means is detachably fixed to the resin bottle body, and more specifically, the resin. At least two sets of the adjusting means are provided on the side surface of the bottle so that the length direction of the adjusting means and the length direction of the resin bottle substantially coincide with each other, and further, one end of the adjusting means or the end thereof. Set a fixed point for pivot in the vicinity , The fixing point is removably or irremovably fixed to either one of the non-contracting portions of the resin bottle adjacent to the contracting portion, and the plurality of adjusting fixing points are adjusted on the adjusting means. Provided at equal intervals or unequal intervals along the length direction of the means,
On the other side of the non-contracting portion, one of the adjusting fixing points is provided with a facing fixing point that is detachably fixed, and the contracting portion is contracted so that the height of the resin bottle becomes a desired height,
In the contracted state, the adjusting means is detachably connected to the facing fixing point through the appropriate adjusting fixing point, whereby the contracted state is maintained and the object is achieved.
The adjusting means is not particularly limited to one kind as long as it can adjust and fix the contraction amount of the contracting portion,
For example, an elongated flat plate-like support plate is used as the adjusting means, one end of this support plate is made continuous by fusion bonding to a resin bottle, and an adjustable fixing point is provided in the direction of the other end. Can be used. Further, it is possible to use a flexible material such as a high-strength thread or cloth (cloth), a part of a rubber belt having a small expansion and contraction, or a loop-shaped material. It is desirable that these adjusting means are symmetrically arranged, but they are not necessarily symmetrically arranged as long as they are arranged so as to be at least mechanically balanced as a whole. The number of the bellows-shaped or spiral-shaped contraction portions (2) may be one, but it is also possible to arrange a plurality of them. When the upper and lower two bellows-shaped or spiral-shaped contracted portions (2) are provided on the side surface of the resin bottle, their lengths may be changed.
As shown in FIGS. 6 to 6, when the corresponding adjusting means for the upper and lower contracting portions are connected by the central non-contracting portion and are fused at a part of the non-contracting portion, the pivot point is provided at the center. Then, the connected adjusting means may be fixed. Regarding the constitution of the fixing means for fixing the height of the contracting portion to a desired position, it is possible to use an appropriate combination of the fixing point on the non-contracting portion and the fixing point on the adjusting means corresponding to this. is there. Various mechanisms such as hooks, slots, velcro tapes, adhesive tapes, loops, and insertion screws can be used, and combinations of these can be fixed points on the contraction portion and fixing means on the corresponding adjusting means. It can be selected as a combination of points. As an example, combinations of slots and protrusions, recesses and protrusions, hooks and holes, loops and hangers, etc. are possible. Some will be partially described in the examples. The material of the bottle body (1) is not particularly limited as long as the effects of the present invention can be substantially obtained as a whole. Flexibility, stability and mechanical strength of the bellows-shaped or spiral-shaped contraction part are such that the carbon dioxide gas from carbonated drinking water or beer etc. filled in the carbon dioxide removal prevention bottle has physical properties at least to suppress natural generation at room temperature. Required. This is applicable to a range of resins having flexibility and stability based on ordinary plasticity, for example, a series of resins starting with vinyl chloride and polyethylene. Of course, polyethylene phthalate which has been widely used in beverage bottles in recent years can also be used. The mechanical strength can naturally be increased to some extent by increasing the wall thickness of the contracted portion. Generally, any material can be used as long as it has a strength to withstand a pressure of about 1 to 2 atmospheres at maximum. The material of the adjusting means may be appropriately determined according to the material of the fixed point. However, mainly from the viewpoint of convenience in manufacturing the resin bottle and ease of use, the same or different resin as the resin of the resin bottle body, metal, fibers such as cotton cloth, and rubber plate can be applied. An example will be described below. Finally, as the resin of the resin bottle, as long as the resin of the present invention can sufficiently bring out the characteristics of the present invention, it is considered that all the resins are useful for the present invention. These have potential as materials starting from the most common to the new resin of the recent years. For example, polyethylene terephthalate resin, polyvinyl chloride resin, polyvinylidene chloride resin, polyethylene resin, polyester resin, polycarbonate resin, polyamide resin, polyacetal resin, polyisoptyrene resin, polyurethane resin, polyoxymethylene resin, polyolefin resin, polychlorotrifluoroethylene Resin, polystyrol resin, polysulfide resin, melamine resin, acrylic resin, etc. are the main ones.

[Operation] After opening the resin bottle and using carbonated drinking water, lightly press the upper part downward, and appropriately adjust the contraction portion until the liquid surface of the remaining carbonated drinking water appears near the outlet surface. Contract. In that state, after tightly closing the lid of the resin bottle, at the fixing point of the non-contracting portion, with the adjusting means, for example, the supporting plate, the provided fixing means, for example, the slot, the hook, the magic tape, the loop, etc. It can be fixed. After fixing the displacement of the contracted portion of the resin bottle so as to balance the displacement dynamically by at least the symmetrical adjusting means, the resin bottle is stored in a refrigerator, a cooler, or a closet. In the case of a plurality of contracting parts, for example, when the bottle side wall is replaced by two upper and lower contracting parts, the non-contracting part is set between the upper and lower two contracting parts of the side wall and the two upper and lower contracting parts are formed. As a common hibot, a part of this non-contraction part can be provided symmetrically. In this case, it is convenient to first contract the lower constriction part so that the height of the lower constriction part is largely contracted to the required position, then contract the upper constriction part finely and apply it for fine adjustment. . Further, when the adjusting means is a flexible support, for example, a belt-like adjusting means in which the fixing means of the magic tape is provided on appropriate parts of both sides thereof, the non-shrinkage is caused by the shrinkage of the shrinking part. The extra flexible Velcro that extends from the tip of the part is folded back from the tip and advanced along the back surface of this support, and after the contraction part is fixed at an appropriate position, If a part of the adjusting means extended to the outside is folded back to the outside and fixed by a magic tape etc. arranged on the folded back inner surface, it can be used meaningfully as a design without disturbing the use. .

[Embodiment] The present invention will be described below with reference to the drawings showing an embodiment. The carbon dioxide gas escape preventing resin bottle of the present invention of the embodiment shown in FIG. 1 comprises a resin bottle body (1) and a pair of elongated support plates (4) as adjusting means. This resin bottle body (1) and a pair of support plates (4)
And are set to function by engaging with each other as follows. The side wall of the resin bottle main body (1) extends from the upper part to the lower part and is replaced by a single bellows-shaped contracting part (2) capable of contracting in the vertical direction. As fixing means to the support plate (4), the upper fixing point (5) of the pivot and the lower fixing point (6) of the slot are symmetrically symmetrical to the non-contracting portion (3) near both ends of the contracting portion (2). Is provided. Each elongated support plate (4) has a slot (7) for pivoting to engage with a fixed point (5) on the upper stage of the resin bottle.
With one end of the pivot slot (7), and when the contraction section (2) is completely contracted, the vertical thickness of the contraction section (2) is taken into consideration, and a space is first provided from the pivot slot (7) by that thickness. A first slot (8) is provided near the middle of the support plate (4) to engage the lower fixing point (6) in the middle of the support plate (4), and a relatively small space is maintained from this slot (8) while A plurality of slots (8) of the same shape and size are prepared in the end direction. The upper pivot fixing point (5) functions as a pivot which is rotatable with respect to the pivot slot at one end of each support plate (4), and is adjusted in a hook shape so as not to come off easily. The lower fixing points (6) on both sides correspond to various heights of the contraction portion (2), and any one of the plurality of adjustment slots (8) in a row is pushed by a finger to the vicinity thereof. Adds a slot size and horizontal cut that allows for mating and engagement. . Here, it is necessary to adjust the degree of volume according to the amount of carbonated drinking water left in the PET bottle, and the vertical height of the contraction part (2) can be adjusted appropriately by each support plate (4). Has been done. FIG. 2 shows a state where the contraction portion contracts. As is clear from the figure, the total length of each support plate (4) should be slightly higher than the bottom surface of the resin bottle and the bottom surface of the resin bottle so that the other end does not get in the way when the contraction portion (2) contracts most. Must be set to. Although not shown, when the support plate (4) is extremely flexible, it is not necessary to be subjected to the above-mentioned geometrical restrictions, and the support plate (4) may be provided near the fixing point on the lower stage of the resin bottle or on the bottom surface. In the vicinity, fold back the part that has passed excessively from the fixed point in the opposite direction and entangle it with the support plate, or tie it to the support plate or fix it to the fixed point (the previous slot (8) engages from the backside). (Possibly), by engaging the slots of the portion after this folding with the inside out, the back-to-back flexible support plate folded after the fixing point at the lower stage of the resin bottle or folded near the bottom of the resin bottle. Can be handled effectively. As a result, it is possible to provide a resin bottle having a long shrinking portion and a resin bottle having a side wall portion in which a plurality of shrinking portions and a plurality of non-shrinking portions are alternately combined. Not only the contracting portion (2) but also the entire resin bottle main body can be maintained mechanically and stably for a long period of time by the support plates (4). Furthermore, although not shown, FIGS. 1 and 2 as described in claim 3
Then, instead of using the fitting of the slot portion of the pivot support plate facing the upper fixing point (5) for the pivot, it is efficient if it is manufactured by fusion or adhesion so that it cannot be removed. Is also cheap. Further, when repeatedly used, there is no fear of losing the support plate, which seems to be very significant from the viewpoint of resource saving. In particular, when refilling carbonated drinking water as a storage container at each home and storing it in a refrigerator, it seems that the support plate is fusion-bonded or irremovably bonded to the storage plate, which is far more advantageous. FIG. 3 shows another embodiment. Here, the case where the shrinking portion (2) is set from the middle portion to the lower portion of the side wall of the resin bottle is shown. In this case, the fixed point (5) on the resin bottle and the pivot slot (7) of the support plate (4) are arranged on the lower side. The slot of the support plate (4) is fixed by adjusting the height of the contraction portion at the fixing fixing point (6) on the upper stage. In this case, since the fixed point (6) is closer to the outlet of the resin bottle as compared with the above-mentioned embodiment, there is an advantage that the adjustment becomes easier. Even in this case, instead of using the fixing points (5) and the pivot slots (7) on the resin bottle, it is efficient if the supporting plate (4) is made non-detachable by fusion or adhesion. Also, the manufacturing cost will be reduced. Further, when repeatedly used, there is no fear of losing the support plate, which is very significant from the viewpoint of resource saving, as in the case of the above-mentioned embodiment. Although not shown, this support plate (4) can be folded back in a belt shape having extremely flexibility, and by using a support plate similar to the additional description of the above-mentioned embodiment, the support plate (4) is near the upper fixing point of the resin bottle. Alternatively, it goes without saying that the back-to-back flexible support plate folded back inside out above the fixing point can be treated in the same manner as in the above embodiment. FIG. 4 shows still another embodiment. When the shrinking part is divided into two parts, the upper part and the lower part of the resin bottle, and the adjusting means for the upper and lower shrinking parts are connected by the non-shrinking part in the center of the resin bottle, and the pivot point is provided symmetrically in the center. In this case as well, a part of the intermediate portion of the support plate (4) may be fused to the non-contractile portion so that it cannot be detached. Therefore, slots are provided on both sides of the support plate (4) in a substantially symmetrical manner, and the heights of the two contracting portions are adjusted and fixed by these slots. Especially in this case, first, the lower contraction portion is largely displaced to determine the approximate height, and after being fixed by the support plate (4), the upper contraction portion is finely contracted to make the inside of the resin bottle smaller. There is an advantage that it is relatively easy to finely adjust the height of the liquid surface of the carbonates. FIG. 5 shows still another embodiment. In this case, an embodiment will be described in which a magic tape is applied as the fixing means regardless of the adjustment fixing points and slots illustrated in the above embodiments. In this case, the height can be adjusted more finely at a more arbitrary height. In this case as well, it goes without saying that the pivotal fixing point (5) and the corresponding pivot slot (7 ') are not undetachably attached by fusion or adhesion. Instead of the rigid support plate (4), it is expedient to use a flexible resin or cloth support plate (11) as the adjusting means. Further, as the combination for forming the mesh used for the Madjik tape, resins such as resin, resin and fiber, metal and fiber and the like can be used. FIG. 6 shows still another embodiment. Here, the fixing means as shown in FIG. 5 is utilized, and as the adjusting means, a belt-like support (10) having high flexibility is used, and the non-contracting portions at the upper and lower central portions are designed to the minimum. This makes it possible to shrink the resin bottle to an extremely compact size. 2 in the figure
The length of each contracted part is relatively large, and both ends protruding from the upper and lower non-contracted parts are folded back and the state is put together neatly by stacking them back to back in the direction opposite to the traveling direction. There is. It is convenient because you can fold it on the side of the resin bottle and handle it easily. The embodiment described above is only an example, and by selecting the fixing means,
The optimum means of adjustment will also be determined by yourself. In the embodiments, the fixing means mainly uses the protrusion and the slot for convenience, but the fixing means is not limited to these, and fixing means such as a hook-shaped engaging portion, a screw method for pushing, a spring method, a magnet method, a loop method, etc. are also applied. I can.

[Advantages of the Invention] [0007] According to the present invention, the refreshing feeling of drinking water is maintained without the carbonation of carbonated drinking water or beer forever, and once opened, for example, carbonated drinking water of cola etc. With the resin bottle of the present invention, it can be stored for a long period of time. In addition, it will be possible to use the space of the refrigerator and cooler efficiently, and the kitchen will be well organized and will be very useful.
