Abstract

[PROBLEMS] A container in which a liquid, solid, powder body, or other article is received for storage. The volume of the container itself can be increased and decreased depending on articles to be received in it. [MEANS FOR SOLVING PROBLEMS] A large number of tubular bodies that can be increased and decreased in number depending on the amount of articles to be received are connected, and stacked on and connected to a tubular body having the bottom. As a result, a large amount of articles can be received in the container. When articles received in the container are consumed, empty tubular bodies can be separated and removed, which leaves less empty space in the container. The size of the entire container is reduced to reduce a space for receiving the container, and oxidation and moisture absorption of received articles can be suppressed. On the contrary, when the tubular bodies are increased in number, the container can cope with an increase in the amount of articles to be received.

Description

Specification

Variable capacity container and its usage

Technical field

[0001] The present invention relates to a container for storing liquids, solids, powders, and other articles for storage, rationalization of handling and storage space when storing food and drinks and other articles, It is intended to prevent moisture.

Background art

[0002] As described in Japanese Utility Model Publication No. Hei 6-59246, when the edges of two containers of exactly the same shape are butted together, the gradients of the edges are staggered and the two containers that are butted are displaced There has been proposed a container that can be used as a container with a lid and can be used alone as a container without a lid.

Problems to be solved by the invention

[0003] However, in this case, when two container edges having the same shape are brought into contact with each other, the capacity is also doubled. However, the upper half acts as a lid, so that a doubled article cannot be put in. This is because when the powder or liquid is added, the upper half overflows when the upper container is removed. As a result, only the lower half of the container can contain liquids, granules, and small items that can easily collapse, and cannot store twice as many articles. If only one container is used, it will be a container without a lid, so unwrapped naked items cannot be stored.

[0004] On the other hand, when storing articles that gradually decrease as they are consumed, it is convenient if the capacity and size of the container itself can be increased or decreased according to the amount of articles that change. For example, in the case of a container filled with cooking oil, it is better to store it in the refrigerator so that it does not easily oxidize, but in a tall container, the container itself remains high even if the contents are consumed and the remaining amount is low Therefore, the space occupied in the refrigerator does not change and is uneconomical. In such a case, it is often necessary to move to a small container, but if the height of the container itself can be lowered as the edible oil content decreases, the space occupied in the refrigerator will also decrease. Other items can be stored in a small space, and the trouble of transferring to a lower container many times can be saved.

[0005] Another problem is that, in the case of an article that easily oxidizes when exposed to a large amount of air, such as oils, it is large when the oxidizable article in the container is consumed and reduced. There is a problem that it becomes easy to oxidize because a large amount of air enters with space remaining. Or, for example, in the case of an article that dislikes moisture absorption, such as laver, if a large space remains in the container when it is consumed and there is little remaining, the laver that is the storage article absorbs moisture in the space. Then there is a problem.

[0006] In such a container that stores a problem article that causes moisture absorption when the large space is generated in the container, the space is reduced when the stored article is consumed. Therefore, if it can be prevented from coming into contact with a large amount of air, the deterioration of the quality of the built-in article can be suppressed.

[0007] The technical problem of the present invention is to pay attention to such a problem, and to reduce the volume of the container itself as the stored articles are consumed and reduced. In addition, it is possible that the same container can be used repeatedly or that additional items can be added. In such a case, it is desirable to increase the capacity of the storage container.

Means for solving the problem

[0008] The technical problem of the present invention is solved by the following means. Claim 1 is a container having a variable capacity structure capable of increasing and Z or decreasing the capacity of the container, and has a bottomed cylindrical body having a bottom, and a single or a plurality of increasing / decreasing cylindrical bodies having no bottom and a lid. And the lid, the increase / decrease cylinder can be detachably connected to the bottomed cylinder, and the lid can be attached to and detached from the increase / decrease cylinder or the bottomed cylinder This is a variable capacity container characterized by being capable of being used.

[0009] Thus, the bottomed cylindrical body having the bottom, the single or plural cylinders without the bottom and the lid, and the lid, the top of the bottomed cylindrical body The above-mentioned increase / decrease cylinders can be detachably connected to each other, so at first, a plurality of increase / decrease cylinders can be connected according to the amount of stored articles, and overlapped with the bottomed cylinders. A large amount of articles can be stored. And when the stored item is consumed and the increase / decrease cylinder part becomes only space, the stored item is not contained. If the increase / decrease cylinder at the upper end is separated and removed, the container will have less space. As a result, the overall size of the container is reduced, so that the storage space for the container is small, and storage in a refrigerator or the like is rationalized. In addition, since the amount of air in the container is also reduced, the acidity and moisture absorption of the stored items can be suppressed. The lid body can be attached to and detached from the increase / decrease cylinder body or the bottomed cylinder body, and the lid body can be shared. Therefore, the lid body can always be sealed.

[0010] Claim 2 is characterized in that the connecting portion between the bottomed cylindrical body and each increasing / decreasing cylinder body or the connecting portion between each increasing / decreasing cylinder body is configured to be airtightly sealed. The capacity variable container according to Item 1. As described above, since the connecting portion between the bottomed cylindrical body and each increasing / decreasing cylinder body or the connecting portion between each increasing / decreasing cylinder body is configured to be hermetically sealed, even if the increasing / decreasing cylinder body is increased / decreased, There is no fear that the stored liquid leaks even in the connecting portion force. In addition, there is no problem that air enters from the outside and the stored items are oxidized or moisture is absorbed.

[0011] A third aspect of the present invention provides the variable capacity according to the first or second aspect, wherein the bottomed cylindrical body and the lid body are additionally provided so that they can be used as separate containers. It is a container. In this way, if the above-mentioned bottomed cylindrical body and lid are additionally provided, it can be used as another capacity variable container by adding the surplus increase / decrease cylinder, and two sets of capacity can be used. Can be used together as a variable container.

[0012] Claim 4 includes a bottomed cylinder having a bottom, a single or a plurality of increase / decrease cylinders having no bottom and a lid, and a lid, and the top of the bottomed cylinder In the capacity variable container in which the increase / decrease cylinder body can be detachably connected to the increase / decrease cylinder body or the bottomed cylinder body, and the lid body is detachable.

In accordance with an increase or decrease in articles to be stored, the number of connected increase / decrease cylinders is increased or decreased.

[0013] A bottomed cylindrical body having a bottom as in claim 1, a single or a plurality of increase / decrease cylindrical bodies having no bottom and a lid, and a lid, the top of the bottomed cylindrical body If a container that can be connected to the increase / decrease cylinder in a detachable manner is used at the beginning, as shown in claim 4, first, a number of increase / decrease cylinders corresponding to the amount of stored articles are used. When a large amount of goods is stored by connecting to the bottom cylinder, and the stored items are consumed, the increase / decrease cylinder is gradually removed to reduce the overall size of the container or the space inside the container. Can reduce the moisture absorption. Conversely, yield When the amount of delivered items increases, it is convenient to increase the volume of stored items by adding additional cylinders to increase the volume.

[0014] Claim 5 is a container having a variable capacity structure capable of reducing the capacity of the container. In addition to the opening chuck means for opening and closing the opening of the bag-shaped container, one or more inner depth chuck means are also provided in the inner depth. If the internal storage is consumed and the internal chuck is reduced below the inner chuck, this inner chuck is left as a new open chuck and can be excised at the upper position. This is a bag-like container.

[0015] As described above, since the plurality of stages of chuck means for the bag-like container are provided, the uppermost stage chuck means that is no longer necessary as a means for closing the opening is cut off when the stored item is consumed and reduced. The size can always be smaller. As a result, it is convenient for storing and storing in a refrigerator or the like, and the space remaining in the bag can always be made smaller, which is effective in preventing oxidation of the stored items and moisture.

[0016] A sixth aspect of the present invention is the bag-like container according to the fifth aspect, wherein two inner chuck means are provided with a separation region interposed therebetween. In this way, since the two inner chuck means are provided with the separation area in between, when the inner chuck means is cut away when the stored items are consumed and reduced, the inner chuck means 1 is also placed on the upper side of the separation area. Since there is a book chuck means, it can be reused as another bag-like container depending on the excised part.

[0017] Claim 7 is the bag-like container according to claim 5 or 6, wherein the inner back chuck means is covered with a covering means for preventing adhesion of stored items. . In this way, since the inner back chuck means is covered with the covering means for preventing adhesion of stored items, it is possible to prevent the stored items from becoming clogged with the internal chuck means and becoming unusable. When the inner and inner chuck means are used to open and close the opening, if the covering means for preventing adhesion is peeled off and removed, it can be used smoothly as the chuck means.

[0018] Claim 8 is a container having a variable capacity structure capable of increasing and Z or decreasing the capacity of the container,

The bottomed cylinder or the upper part of the lower increase / decrease cylinder is superposed on the inner lower part of the upper increase / decrease cylinder to which the lid is attached / detached, and the upper end inner circumference of the upper increase / decrease cylinder and the bottomed cylinder Or, in a stretched state where a flexible tubular film is bonded and fixed to the inner periphery of the upper end of the lower increase / decrease cylinder, The capacity variable container is characterized in that it can be stored. Cylindrical films include cylindrical sheets and membranes.

[0019] In this way, an extended state in which a flexible tubular film is bonded and fixed to the inner periphery of the upper end of the upper increasing / decreasing cylinder and the upper end inner periphery of the bottomed cylindrical body or the lower increasing / decreasing cylinder. After removing the lid and consuming all the stored items in the upper increase / decrease cylinder, the upper increase / decrease cylinder is moved to the lower bottomed cylinder or the lower side. The capacity can be reduced as a whole because it can be pushed and shrunk to the increase / decrease cylinder side. At this time, the cylindrical film may be stored between the inner and outer cylinders, or may be stored in the lower cylinder. By pulling out the increase / decrease cylinder and extending the cylindrical film, it can be used for storage as the original large-capacity variable capacity container.

[0020] A ninth aspect of the present invention is the variable capacity container according to the eighth aspect, characterized in that it has stopper means for preventing the movement of the increase / decrease cylinder. Thus, since the stopper means for preventing the movement of the increasing / decreasing cylinder body is provided, it is possible to prevent the upper increasing / decreasing cylinder body from falling due to its own weight or the weight of the stored item and to stabilize it.

The invention's effect

[0021] As in claim 1, it has a bottomed cylinder having a bottom, a single or a plurality of increase / decrease cylinders having no bottom and a lid, and a lid. Since the above-described increase / decrease cylinders can be detachably connected to each other, first, a plurality of increase / decrease cylinders are connected in accordance with the amount of stored articles, and overlapped with the bottomed cylinders. If so, a large amount of articles can be stored. Then, if the stored product is consumed and the portion of the increase / decrease cylinder becomes only space, the container with less space can be obtained by separating and removing the increase / decrease cylinder at the upper end that does not contain storage. As a result, the overall size of the container is reduced, so that the storage space for the container is small, and storage in a refrigerator or the like is rationalized. Since the force and the space in the container are also reduced, the acidity and moisture absorption of the stored items can be suppressed. The lid body can be attached to and detached from the increase / decrease cylinder body or the bottomed cylinder body, and the lid body can be shared. Therefore, the lid body can always be sealed.

[0022] As described in claim 2, since the connecting portion between the bottomed cylindrical body and each increasing / decreasing cylinder body and the connecting portion between each increasing / decreasing cylinder body are configured to be hermetically sealed, the increasing / decreasing cylinder body Even if the number is increased or decreased, there is no risk of the stored liquid leaking from the connection. Also, external force air enters and the stored items There is no problem of oxidation or moisture absorption.

[0023] As in claim 3, if the bottomed cylinder and the cover are provided in excess, the extra increase / decrease cylinder can be added to use as another capacity variable container, Can be used together as a set of variable capacity containers.

[0024] A bottomed cylindrical body having a bottom as in claim 1, a single or a plurality of increase / decrease cylindrical bodies having no bottom and a lid, and a lid, the top of the bottomed cylindrical body If a container that can be connected to the increase / decrease cylinder in a detachable manner is used at the beginning, as shown in claim 4, first, a number of increase / decrease cylinders corresponding to the amount of stored articles are used. When a large amount of goods is stored by connecting to the bottom cylinder, and the stored items are consumed, the increase / decrease cylinder is gradually removed to reduce the overall size of the container or the space inside the container. Can reduce the moisture absorption. Conversely, when the amount of stored items increases, it is convenient to increase the volume of stored items by adding an increase / decrease cylinder to increase the volume.

[0025] Since the plurality of stages of chuck means are provided in the bag-like container as in claim 5, the uppermost stage that is no longer necessary as means for closing the opening when the stored item is consumed and reduced. The chuck means can be cut out to keep the size always smaller. As a result, it is convenient for storing and storing in a refrigerator and the like, and the space remaining in the bag can always be made smaller, which is effective in preventing oxidation and moisture in the stored items.

[0026] As in claim 6, since the inner back chuck means is provided with the separation region in between, the stored material is consumed and reduced, and when the inner back chuck means is excised, the separation region Since there is also one chuck means on the upper side, it can be reused as another bag-like container depending on the excised part.

[0027] As described in claim 7, since the inner back chuck means is covered with covering means for preventing adhesion of stored items, it is possible to prevent the internal chuck means from becoming clogged with stored items and becoming unusable. The When the inner and inner chuck means are used for opening and closing the opening, if the covering means for preventing adhesion is peeled off and removed, the inner chuck means can be used smoothly as the chuck means.

[0028] As described in claim 8, a flexible tubular film is bonded and fixed to the inner periphery of the upper end of the upper increase / decrease cylinder having the lid and the upper end inner periphery of the bottomed cylinder or the lower increase / decrease cylinder. Since the product can be stored in the extended state, the cover is removed and all the stored items in the upper increase / decrease cylinder are consumed. After that, the upper increase / decrease cylinder can be pushed into the lower bottomed cylinder or the lower increase / decrease cylinder to be shrunk, so that the capacity can be reduced as a whole. At this time, the cylindrical film may be stored between the inner and outer cylinders, or may be stored in the lower cylinder. By pulling out the increase / decrease cylinder and extending the cylindrical film, it can be used for storage as the original large-capacity variable capacity container.

[0029] Since the stopper means for preventing the movement of the increasing / decreasing cylinder body is provided as in claim 9, the upper increasing / decreasing cylinder body is prevented from being lowered by its own weight or the weight of the stored item, and stable. Can be made.

BEST MODE FOR CARRYING OUT THE INVENTION

[0030] Next, an embodiment of how the variable volume container according to the present invention is actually realized will be described. FIG. 1 is a perspective view showing the entire volume of a variable capacity container according to the present invention. Three increasing / decreasing cylinders 2 are connected to each other on the bottomed cylindrical body 1 at the bottom, and a lid 3 is attached to the uppermost part. The number of intermediate increase / decrease cylinders 2 is arbitrary. Moreover, in the case of illustration, it has a cylindrical shape, but is not limited to a cylindrical shape, and may be elliptical or polygonal.

FIG. 2 is a longitudinal sectional view of the variable capacity container of FIG. 1, wherein 1 is a bottomed cylinder, 2... Increase / decrease cylinder, and 3 is a lid. The increase / decrease cylinder 2 is overlapped and connected on the bottomed cylinder 1 having the bottom B, and the plurality of increase / decrease cylinders 2 are overlapped and connected to each other. A lid 3 is mounted on the uppermost increase / decrease cylinder 2.

[0032] The connecting portion 4 between the bottomed cylindrical body 1 and the increase / decrease cylindrical body 2 has a detachable structure. The connecting portion 5 between the adjacent increase / decrease cylinders 2 and 2 also has a detachable structure. Further, the connecting portion 6 between the uppermost increase / decrease cylinder 2 and the lid 3 also has a detachable structure. Therefore, at first, if the stored items are in the hi position, that is, in all the cylinders, they are stored in a refrigerator or the like in the state of a four-stage cylinder.

[0033] When the storage in the variable capacity container is consumed and reduced to the h2 position, the uppermost increase / decrease cylinder 2 is not functioning as a container. The lid 3 can be attached to the increase / decrease cylinder 2. As a result, the storage space for the refrigerator can be reduced. If the stored items are further consumed and reduced to the h3 position, all the increase / decrease cylinders 2 will not function as containers, so remove them from the connecting part 4 and place the lid 3 on the bottomed cylinder 1 Wearing Can be kept. As a result, the bottomed cylinder 1 is the smallest unit, and the storage space in the refrigerator is also minimized. In addition, since the space in the variable capacity container is reduced, moisture absorption and oxidation are also suppressed.

[0034] On the other hand, if the stored item only enters the h3 position and you want to purchase additional items and increase the amount of storage, add a vacant increase / decrease cylinder with connecting part 4. You can also. Then, if another increase / decrease cylinder 2 is added at the connecting portion 5 on the added increase / decrease cylinder 2, the capacity of the container can be further increased and a larger amount of storage can be stored.

[0035] The connecting portions 4, 5, and 6 in FIG. 2 are screw-type forces. This is an example, and other connecting structures such as a Nonnet mechanism are also possible. In addition, if an O-ring 7 made of rubber or soft synthetic resin is fitted below the threaded portion of each connecting portion, the air can be sealed in and out, so that the acidity of the stored items can be reduced. Can absorb moisture.

FIG. 3 shows another embodiment of the connecting portion, which has a structure that serves both as connecting and fixing and an airtight seal.

An O-ring 8 is wound around and fixed to the outer periphery of one opening 10 of the increase / decrease cylinder 2, and an arcuate groove 9 into which the O-ring 8 can be fitted is formed on the inner periphery of the other opening 11. Therefore, when connecting the increase / decrease cylinders 2 and 2, when the flange ring 8 side of the adjacent increase / decrease cylinder 2 is inserted into the concave groove 9 side of the opening 11, the connection part 12 is formed. The outer peripheral portion of the ring 8 is inserted into the groove 9.

[0037] Since the eaves ring 8 is made of rubber or soft synthetic resin, when the opening 10 side is pushed into the opening 11 side, the eaves ring 8 is elastically inserted into the recessed groove 9. Thus, the state of the connecting portion 12 is obtained. As a result, the opening 10 side and the opening 11 side are firmly connected and fixed to each other. When a force in the direction of pulling away from the opening 11 side is applied from the opening 11 side in the state of being connected and fixed like the connecting portion 12, the heel ring 8 is recessed against the elasticity of the heel ring 8. Since they come out of 9 and separate from each other, it is easy to remove the opening 10 side and the opening 11 side.

[0038] In addition, as shown in Fig. 1, in a state where a large number of increase / decrease cylinders 2 are connected, if the container is rotated by holding the container at the lower end and the upper end by hand, it is separated at which connection part 4 or 5 If you don't know what you are doing, the contents may spill out. To avoid this, attach tape or label to the outer periphery of the connecting parts 4 and 5 in Fig. 1, and remove the tape or label only from the connecting part that needs to be separated, or cut the tape or label. If so, it is possible to separate only that place Become. In addition, a hook for preventing separation may be provided at the connecting portion and hooked.

[0039] Also in the case of the structure using the O-ring 8 as shown in Fig. 3, when only the upper and lower containers are pulled, the place to be separated is not constant. In this case as well, it is preferable to attach a tape, a label, etc. to the outer periphery of each connecting portion and peel off the tape, the label, etc. only where it needs to be separated, or make a cut on the tape, the label, etc. Of course, it is possible to hook the hook and remove the hook only from the connecting part that needs to be separated.

[0040] Alternatively, if a structure of connecting and fixing with a buckle or the like is adopted, it can be dealt with by removing the buckle only at the separation portion.

[0041] When the capacity variable container is used, if the bottomed cylindrical body 1 and the lid body 3 are additionally provided, there is an advantage that the container can be used as another separate container. That is, in FIG. 2, if another bottomed cylinder 1 and a lid 3 are provided, the increase / decrease removed when the increase / decrease cylinder 2 on the upper side is consumed up to the h2 position in FIG. Connecting cylinder 2 to another bottomed cylinder 1 increases the capacity of another container. Therefore, if two sets of the bottomed cylinder 1 and the lid 3 are prepared and the increase / decrease cylinders 2 are interchanged, they can be used as two sets of variable capacity containers.

FIG. 4 is an example in which the idea of the present invention is applied to a bag. In the case of a container that also has a bag force, there is known a structure in which chuck means that also has a well-known uneven structure attaching / detaching structure force is provided on the inner surface of the opening so that the opening can be chucked and fixed. However, if the amount of stored items becomes small, it is difficult to take out the items remaining at the bottom. Or in the case of an article with strong adhesiveness, it will be difficult to open the bag because it will be difficult to open the bag because the bag will stick together and stick together. Inconvenience occurs. Therefore, according to the present invention, such a chuck 13 is formed in a plurality of stages, for example, three stages as shown in FIG. That is, there are three stages: an opening chuck 13a that opens and closes the opening, and inner and inner chucks 13b and 13c that are located in the inner inner part. However, as shown in Fig. 4 (1), when the stored item 14 is filled, the lower two-step inner back chucks 13 and 13 are fitted with the protrusion 13p and the protrusion 13p. It is separated from the groove 13u.

[0043] In this bag, as shown in (2), as a result of opening the opening chuck 13a at the upper end and consuming the article inside, if the article 14 force decreases to the position of ¾ι2, the second stage from the top Back chuck 13 If b is an open chuck, the internal article 14 can be easily taken out, and a large space is left in the bag to prevent the internal article 14 from being oxidized or damp. In this case, since the upper end opening chuck 13a is not necessary, it is preferable to cut and remove it at the portion of the chain line al above the inner back chuck 13b to make the inner back chuck 13b a new opening chuck. When further consumed and decreased to the h3 position, the inner chuck 13b in the second stage from the top is also cut and excised at the position of the chain line a2 above the inner chuck 13c in the lowermost stage. It is better to leave only the chuck 13c. As a result, the bottom inner chuck 13c becomes a new open chuck.

[0044] In this way, when the opening chuck at the upper end that is no longer necessary as a storage means is cut off, as a result of consumption, it is cut every time the stored item 14 becomes deeper, so that the stored item can be prevented from becoming too deep. Even when the stored item remains in the bag, the problem that the bag is too deep and remains at the bottom of the bottom, making it difficult to remove the stored item. Therefore, even when a container with strong adhesiveness is contained, the area where the bag sticks and is difficult to open becomes shallow, which makes it easy to handle.

[0045] In this way, when the inner chucks 13b and 13c in the second and lower stages from the top are excised, if the inner chucks 13b and 13c are doubled, the excised portions are discarded. Instead, it can be reused as a separate bag. That is, as shown in FIG. 5, two chucks 13b ′ 13b and 13c ′ 13c are provided on both sides of the separation regions Al and A2. Assuming that the variable capacity container is cut out in the separation region A1 as a result of consuming the article 14 to the h2 position, the cut-off region C thus cut has chucks 13a'13b on both upper and lower sides. Therefore, if the upper and lower chucks 13 a ′ 13 b are closed, they can be reused as another bag-like container. In this case, one of the chucks 13a and 13b is closed and the other is opened and closed. As a use, for example, it is convenient to divide the stored item 14 into a lunch box or the like, or to carry it when going out. Needless to say, the articles placed in the excised separate containers are optional. If not used as a separate container, cut it above the upper chucks 13b and 13c of the separation areas Al and A2, and leave two chuck means 13b '13b or 13c' 13c. Since a double chuck can be used, even if one of the chuck means is out of order, it can be reliably closed.

[0046] In the case of a bag-like container as shown in FIGS. 4 and 5, the chucks 13b and 13c are provided inside the container. , Force depending on the type of contents The ridges 13p and grooves 13u of the chuck may become dirty or clogged with the contents, which may cause inconvenience when closing the chuck. In order to prevent this, as indicated by the chain line t, it is desirable that the upper force of each protrusion 13ρ ··· and the groove 13u ··· be covered with a film, sheet, film, tape, or the like attached in advance. . Then, when using the inner back chucks 13b and 13c remaining after cutting away the unnecessary portions, the film, sheet, membrane or tape t is peeled off and discarded, and the protruding strips 13p and the groove portions are removed. If 13u is exposed, it can be used smoothly.

[0047] The means for covering the protruding ridges 13p and the grooves 13u of the chuck are not limited to tapes t. For example, a paste-like or putty-like plastically deforming substance is applied to the protruding ridges 13p or the grooves 13u. The upper force can also be applied or filled. Of course, it will harden after a certain period of time, so there is no problem in its use as a container for storing items. Then, the unused portion that has increased after consumption of the stored items is excised, and when the remaining inner chucks 13b and 13c are used, the paste-like and putty-like plastic deformation products are peeled off and discarded, and the projections are projected. If the groove 13u facing the strip 13p is exposed, it can be used as a chuck. The bottom of the bag-like container can be accommodated in a larger amount by attaching a well-known flange 15 as shown in FIG. The chuck means is not limited to the illustrated example as long as it has a chuck function. The opening chuck means 13a includes a slide fastener and a zipper that are opened and closed by a slider.

[0048] FIG. 5 shows an embodiment in which the capacity is reduced by cutting away the upper unnecessary portion that has increased as a result of consuming the stored items, whereas FIG. 6 is an embodiment in which the capacity is reduced by reducing the whole. is there. 16 is a cylinder made of synthetic resin, metal plate, etc., and consists of multiple types: large size L, medium size M, and small size S. The upper end of the cylindrical film 17 is bonded to the inner upper end of the L size cylinder 16, and the lower end is bonded to the inner upper end of the M size cylinder 16. Similarly, the upper end of the cylindrical film 18 is attached to the inner upper end of the M size cylinder 16, and the lower end is bonded to the inner upper end of the S size cylinder 16.

[0049] As shown in the figure, it is important that the upper end of the lower cylinder 16 is inserted into the lower end of the upper cylinder 16 to produce a slight overlap region D. The difference G between the inner diameter of the large cylinder 16 and the outer diameter of the lower small cylinder 16 in this overlap region D is slight, and the force gap G depends on the thickness and flexibility of the films 17 and 18. within mm or l ~ 2m may be within m.

[0050] Thus, in the configuration in which the medium size cylinder M is positioned on the small size cylinder S with the bottom B and the large size cylinder L is positioned on the upper side, the stored item 14 is on the upper large size. Assuming that the cylinder L is inserted, the film 17 is pressed against the inner surface of the large size cylinder L by the stored item 14, and the large size cylinder L is held by the stored item 14. Similarly, the film 18 is pressed against the inner surface of the medium-sized cylinder M by the stored item 14, and the medium-sized cylinder M is held by the stored item 14.

[0051] Now, when all the stored items 14 in the upper large-sized cylinder L are consumed, the stored items 14 to be held are lost, and the holding force is reduced. As a result, the upper large-sized cylinder L descends by its own weight. At this time, as shown in FIG. 7 (1), the film 17 is placed in the gap G between the inner surface of the large size cylinder L and the outer surface of the medium size cylinder M while being separated from the inner surface of the large size cylinder L. Finally, at the position where the upper end of the large size cylinder L is aligned with the upper end of the medium size cylinder M, the rubber cylinder or other knives / kin P is pushed into the gap G. Prevent further descent.

[0052] Next, when the stored item 14 in the medium-sized cylinder M is also consumed and the force for holding the medium-sized cylinder M is lost, the medium-sized cylinder M and the large-sized cylinder L outside thereof are also lowered. Thus, the state of Fig. 7 (2) is obtained. In this way, when the stored item 14 in the larger cylinder on the upper side is consumed, it descends and finally reaches the height of only the small size cylinder S1 as shown in Fig. 7 (2). It becomes capacity. In this state, it is preferable to pack a rubber band to be the packing P in the gap between the inside of the medium size cylinder M and the outer surface of the small size cylinder S. Thus, when the knock P is packed, the medium size cylinder M and the small size cylinder S do not fall off due to the weight of the storage item 14 when the upper large size cylinder L is held.

FIG. 6 and FIG. 7 are examples of three stages, but four stages or more or only two stages are possible. To replenish the contents 14 after consuming the inside of the small size cylinder S, remove the above-mentioned knocking P, pack the packing P with the medium size cylinder M raised, and fix it. , Replenish the contents 14. When refilling, the large size cylinder L is also lifted, and the packing P is packed and fixed, and then the stored items 14 can be put in three stages as shown in Fig. 6 and reused.

[0054] The example of the cylinder 16 has been described as each of the containers L, M, S. There is no reason to be. In addition, when the stored item 14 is liquid or miso, etc., the upper cylindrical container can be held, but in the case of powder, the holding power cannot be expected so much. It must be wound around the outer circumference of the small-diameter cylinder 16 and used as a stopper. By always packing and wrapping the packing P and securing the stopper function at all times, the cylinders L and M can be fixed in the middle of expansion and contraction. When packing P is packed in gap G, if it is not fully packed and is partially pulled out, it can be easily pulled out and removed when cylinder 16 is expanded or contracted. If knockin P is a rubber band, etc., it will deteriorate over time and its elasticity will decrease, so it will need to be replaced from time to time. The knockin P may be an O-ring. The films 17 and 18 to be bonded by the bonding portion 19 on the inner periphery of the upper ends of the cylindrical containers L, M, and S may be separate or may be a continuous unit. The films 17 and 18 include thin materials called various sheets and films that are highly flexible. As the material, a synthetic resin with high air tightness and liquid tightness is suitable. The film 18 can also be attached so as to cover the entire inner surface of the small size cylinder S as shown in FIG.

[0055] The cylinders 16 for the containers L, M, and S do not require the connecting means as shown in FIGS. 2 and 3, and thus have the simplest shape. As a result, it is possible to realize materials that are difficult to process and mold, such as ceramics, glass, and wood, so that containers with excellent aesthetics are possible. Therefore, it can be used not only for containers used in a refrigerator, but also as a seasoning container, accessory container, vase, interior goods, etc. that are always used on a table. As a unique container for various purposes that can be expanded and contracted according to the amount of storage, it is useful even without a lid. The lid 3 can be fixed or removed by providing circumferential grooves or ridges on the outer peripheral surface of the large cylinder L. The size in the height direction of containers L, M, and S of each size also corresponds to the outer diameter size, and the force that makes the largest container L the highest and the smallest container S the lowest. Figure 7 (2) This is convenient when storing each other.

Industrial applicability

[0056] As described above, when the container is initially used as a large-capacity container corresponding to the amount of stored items, and the stored items are consumed, and the space increases, the upper area where no stored items are contained. Removing or shrinking will result in a container with less space. As a result, the overall size of the container can be reduced, the storage space in the refrigerator can be reduced, and the need to transfer to a small container can be saved. The Furthermore, there is also an effect that the acid absorption of the stored item can suppress moisture absorption.
