Description

  The present invention relates to a liquid storage container, and more particularly to a liquid storage container having at least two surface portions parallel to each other and capable of being stably stacked even in a narrow storage space.

  In recent years, there has been a growing interest in drinking water that is constantly ingested in response to health-oriented improvements. Therefore, various water purifiers have been developed and are commercially available. As a water purifier, a water purifier is installed near the faucet and purified every time tap water is used. A device that stores purified water in a bottle and takes out the purified water in the bottle via cold water or hot (hot) water when in use has been developed.

  In a bottle used for such a hot / cold water supply machine, a spout with a small-hole cylinder protrudes from an upper part of a cylindrical or rectangular tube. Such a bottle is generally manufactured by a blow molding method with high productivity and good shape stability.

  That is, an extruded molded resin tube (main body barrel) is inserted into the mold, and a pre-molded small-hole cylindrical spout (neck) is attached to the upper portion of the main body barrel. Then, air is blown from the top through this spout to form a bottle.

  Since the bottle formed in this way has a protruding portion as a spout formed on the upper part thereof, when a large number of bottles are transported, stored or displayed, the use space is wasted. For this shape, a large space is required.

Therefore, in order to be able to stack a large number of bottles, a proposal has been made that can be stacked in multiple stages via a bottle tray provided with a concave fitting part capable of fitting the neck part (for example, Patent Document 1).
JP 2003-81271 A

  However, the above prior art requires a tray provided with a complicated fitting portion adapted to the shape of the bottles to be stacked. For example, when a large number of bottles are stored using such a tray, It is necessary to prepare trays that do not exist, leading to a rise in manufacturing costs, storage costs, and distribution costs of such trays, and because the trays have a flat spread, they want to stack in the height direction in a narrow space. There is a problem that it is not possible to deal with requests to do so.

  Therefore, the problem to be solved by the present invention is to reduce the shape of the bottle itself by a simple method in view of the circumstances of the above-described conventional technique, so that the storage cost does not increase and the space is narrow. However, it is to provide a liquid container that can be stably stacked.

  The above-mentioned subject is achieved by the invention described in each claim. That is, the liquid storage container according to the present invention is characterized in that, in a container having at least two surface portions parallel to each other, the liquid storage container has a protruding portion for putting liquid in and out of one of the surface portions, and the protruding portion on the other of the surface portions. And having a recess that can be fitted.

  According to this configuration, it is possible to stably stack and stack a plurality of containers even when storing or transporting a liquid container only by changing a part of the container shape. It is possible to make the space to be as small as possible, and it is not necessary to prepare and prepare a tray or the like separately.

  As a result, by changing the shape of the bottle itself by a simple method, it has been possible to provide a liquid container that can be stably stacked even in a narrow space without causing an increase in storage cost or the like.

  It is preferable that one of the surface portions is an upper surface portion, the other of the surface portions is a lower surface portion, and the container has a substantially cylindrical shape, and a shallow dent that can be gripped is formed in the container side surface portion. .

  According to this configuration, the gaps between the liquid storage containers stacked in multiple stages can be reduced as much as possible, and when storing and transporting a large number of liquid storage containers, the space is further reduced and the required space is made effective. Furthermore, since the liquid container can be easily moved by a human hand through the recesses on the side surfaces, handling becomes easy and convenience is enhanced.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 illustrates a state in which liquid storage containers 1 (hereinafter, simply referred to as “containers”) according to the present embodiment are stacked. This container 1 has an entrance / exit part 1a (corresponding to a protruding part) for injecting a liquid into a substantially cylindrical container made of a transparent polycarbonate resin and taking out the liquid from the container 1, and is an abbreviation of the upper surface part 1b. While projecting from the central portion, the bottom portion 1c has a concave portion 1d into which the entrance / exit portion 1a of another container 1 can be fitted. The entrance / exit portion 1a and the recess 1d need only be fitted smoothly so that the gap does not increase, and the shape, the depth of the recess, the position, and the like can be appropriately selected in consideration of the relationship with the internal volume.

  This container is convenient because it is transparent so that the current amount of stored liquid can be easily seen, has no health and safety problems, has excellent flavor, and can be stored or transported. Since it has weather resistance and the like, it is suitable for use as a container for storing various drinking water.

  Moreover, as shown in FIG. 1, in order to mount the entrance / exit part 1a of the lowest container 1, it is preferable to provide the receiving stand 2 in which the recessed part 2a was formed in the upper surface side. Providing such a cradle 2 is advantageous because stability during storage increases and the storage position is determined.

  Although not shown, the tip of the container inlet / outlet portion 1a is threaded, and a cap (not shown) is screwed and attached to be tightly plugged. However, as long as the liquid contained in the container does not easily leak, a sealing mechanism other than screwing may be employed, and another sealing mechanism may be further stacked.

  As a method for producing the container 1, a blow molding method having high efficiency is generally used in producing a hollow resin product. That is, the raw material thermoplastic resin is heated and melted to produce a pipe or sheet-like extruded product, the mold is closed when it reaches a predetermined length, and air is blown out from the center of the die for extrusion. The molded product is expanded, and the molded product is molded in close contact with the inner surface of a mold having a predetermined shape. After blow-molding into a predetermined container shape, a pre-molded small-hole cylindrical body (pre-molded product) that becomes the container entrance / exit part 1a is mounted at a predetermined position on the upper surface of the container. In addition, as a method for manufacturing the container 1, various blow molding methods other than those described above can be applied, and the method is not particularly limited to the manufacturing method.

  Specifically, for example, an 18 L polycarbonate container having the shape shown in FIG. 1 is manufactured by blow molding, filled with drinking water, and stacked in four stages as shown in FIG. be able to. At that time, if at least two shallow dents 1e that can be grasped with both hands are formed on the side surface of the container, both hands are placed in the dent 1e so that both hands are held against the container 1 and held. Thus, it becomes easy to carry the containers, and it becomes easy to stack the containers sequentially from the bottom. Of course, you may make it provide the handle which can be hold | gripped with both hands in the side part of a container. Further, the number of stages is not limited to four.

  1 and 2, the container 1 is disposed with the recess 1d of the container 1 disposed upward facing the inlet / outlet portion 1a facing upward. May be stacked. In this way, since the bottom having a larger area can be placed on the floor surface or the like, more stable stacking storage is possible in a narrow space. Of course, when a large number of stacked multistage containers are stored or transported, a fence or bundling with a band can be appropriately performed.

  Next, a specific example of the container 1 will be described. The container 1 has a substantially cylindrical shape, and a polycarbonate container having an internal volume of 18 L having the shape shown in FIG. 3 was produced by a blow molding method. The container 1 shown in FIG. 3 has an outermost diameter d = about 29 cm and a height h = about 29 cm, the outer diameter D of the entrance / exit portion 1a = about 6 cm, the height H of the entrance / exit portion 1a = about 8 cm, and the recess 1d. The outer diameter D ′ is about 6.5 cm, and the height H ′ of the recess 1 d is about 8.5 cm. Among these, the outer diameter D of the entrance / exit portion 1a = 5 to 9 cm, the height H of the entrance / exit portion 1a = 6 to 10 cm, the outer diameter D ′ of the recess 1d = 5.5 to 9.5 cm, and the height H ′ of the recess 1d. = 6.5 to 10.5 cm is preferable.

[Another embodiment]
(1) In the above embodiment, a cylindrical container has been described as an example, but the container shape is not limited to this, and may be a rectangular tube. For example, if the bottom shape is a triangular cylinder shape, it can be placed in the corner of the room during storage, and the storage space can be used effectively. If the bottom shape is a square cylinder shape, it is stacked in multiple stages. In addition, even when they are arranged in a plane, they can be stored densely without generating a gap, or a similar storage space can be ensured even if a square cylinder with a regular hexagonal bottom is used.
(2) In the above embodiment, an example was shown in which the inlet / outlet portion 1a of the container was provided at one location on the upper surface portion thereof, but as shown in FIGS. It may be provided near the bottom of the container. The faucet 3 can be attached to the container by various methods such as screwing, welding, and adhesion. In that case, as shown in FIG. 5, if the container is formed in a shape in which the bottom portion is cut out and the faucet 3 is attached to the side surface of the cutout portion, the same stacking as in FIG. 2 is smaller. This is preferable because it is possible with space. Of course, two or more faucets 3 may be provided.
(3) The weighing device may be attachable to the entrance / exit part 1a of the container. In other words, when a predetermined amount of liquid is taken out from the container, it is convenient to increase the convenience by taking out only a necessary amount (for example, 100 mL) while measuring it.
(4) An automatic or manual pump that can quickly store or take out the stored liquid may be attached to the inlet / outlet portion 1a of the container.
(5) Reinforcing ribs may be provided continuously or intermittently around the side surface, particularly in the side surface portion of the container shown in the above embodiment. When transporting or the like, it is easy for the containers to come into contact with each other. However, providing the rib in this way is preferable because the container is difficult to be damaged. The rib on the side surface of the container can be easily formed at the time of molding by a method such as providing a concave portion for rib formation on the mold surface in advance.
(6) In the above embodiment, a transparent polycarbonate container has been described as an example of the container material. However, the container material is not limited to this, and is safe and hygienic for storing various drinking water. There is no problem as long as it has strength and weather resistance that can be stored or transported, and may be translucent or opaque.
