Definitions
- the invention a space saver container, has wide application where efficient utilization of space is critical.
- the embodiments present herein are primarily directed towards containers used for storing consumables in refrigerators or closets with limited free space.
- the concept is simple: container volume must match the content volume through out the process of content consumption to increase shelf space at the same rate as the rate of consumption of the contents.
- a measure of storage efficiency is the ratio of the volume of the material in a container to the volume of the container. When a container is full at the time of purchase the storage efficiency is the highest, nearly 1.
- conventional containers maintain the container volume and shelf space utilization even though the contents are depleted through progressive consumption. In conventional container as the volume of the material contained depletes the storage efficiency falls. When the container is half full the storage efficiency becomes 0.5.
- Containers built to the concept of space saver container are volume adjustable to shrink in volume to the extent there is free space within the container.
- the storage efficiency of containers built to this concept are capable of maintaining their storage efficiency of nearly 1 through out the period they contain material, depleted or not.
- Space saver container based milk container would release space to the refrigerator as the milk is consumed. It is possible to stock up on items that are almost over as more and more space becomes available due to combined effect of other containers built to the new concept.
- the availability of space makes other items in the refrigerator more accessible particularly the ones stored along the back wall. To time a visit to the grocery store precisely when the contents are over is difficult and sometimes impossible. Breakfast without milk becomes a reality.
- space saver container 's ability to release shelf space as soon as the contents are consumed enables re stocking activity to begin well before the item is totally consumed.
- space saver container improves accessibility, improves re stocking window and reduces the risk of running out of essential items.
- the conventional containers in the instance of milk allow on an average a 12-hour window to re stock to have it available for breakfast the next day. This window can be considerably improved with a container built to the concept of space saver container.
- the disadvantage of fixed volume container storage is eliminated with adaptable volume design of the space saver container. By combining the space saver container concept with standard manufacturing practices a wide variety of storage solutions are possible.
- the embodiments presented herein address application of the concept to fluids and solid objects as in the case of milk, bottled water and ice cream but it is recognized that the concept can be extended to other material, objects and systems that require efficient space utilization.
- the ideal is a storage efficiency of 1 even when the volume of the stored entity changes.
- Embodiment 1 is the application of the concept to half-gallon container for milk using elastic material to create a container composed of bellow biased for maximum extension.
- the bellow can be compressed and in the process behaves like a compressed coil spring that is stabilized through a restraint means, which enables the new shape to be stable.
- the reduction of volume is accompanied by reduction of footprint.
- the restraint means is a ball chain.
- One end of the chain is a ball called anchor ball and the other end is a smaller ball called the latch ball.
- the user compresses the surfaces and pulls on the latch ball to take up the slack. The appropriate ball in sequence gets latched to hold the new shape of the container.
- Embodiment 2 is the application of the concept to larger heavier containers that need a special handle. Balanced weight distribution becomes a requirement and has been addressed using an elastic material to create a pair of bellows symmetrically placed around the handle as a part of the container enclosure.
- the restraint means is identical to embodiment 1. Space saving is accompanied by reduction of footprint.
- Embodiment 3 is the application of the concept using a non-elastic material to create container that can collapse by creating folds in the construction material like stiff paper sheets. (A single fold is a particular case of a bellow).
- the restraint means is different from embodiment 1 & 2. Space saving is accompanied by reduction of footprint.
- Embodiment 4 is the application of the concept with the volume shrinkage taking places transverse to the ground or the seat of the container. This application shows its adaptation to solids like ice cream containers. Space saving is through reduced container height without change of footprint.
- FIG. 23 contrasts the front of a refrigerator shelf and an ice box laden with space saver containers on day 1, when the contents are full, to day 4 when it is assumed that more than half the contents are gone.
- space saver containers typically such containers would be loaded with milk, fruit juice, water, yogurt and ice creams.

Abstract
Space saver container is a concept of shrinking containers so that its volume matches the volume of the contents. Thus as the contents are progressively consumed the container can progressively reduce in volume freeing up space outside the container for example in the closet or refrigerator where it may be stored. The reduction can be tailored to the situation in which the container is normally used. Thus in the case of say milk cartons the container reduces its foot print but in the case of ice-cream container the height is reduced thus increasing stacking space. The containers available today can create shelf space only when the contents of the containers are gone and when they are ready to be removed for disposal. The concept of space saver container volume reduction is enabled by a collapsible bellow structure that is biased to attain its maximum volume. The user forces the bellow shape to contract thus shrinking the container to match the volume of the content. To keep the shrunken volume stable a restraint means suitable to the type of container is used to balance the bias in the structure that keeps it at maximum volume. The versatility of the concept enables a wide application in situations where material is stored and space is at a premium. Additional functionality of the bellow structure can be designed into the structure to enable it to adopt a freestanding stance suitable to the application.
Description
- The invention, a space saver container, has wide application where efficient utilization of space is critical. The embodiments present herein are primarily directed towards containers used for storing consumables in refrigerators or closets with limited free space. The concept is simple: container volume must match the content volume through out the process of content consumption to increase shelf space at the same rate as the rate of consumption of the contents. A measure of storage efficiency is the ratio of the volume of the material in a container to the volume of the container. When a container is full at the time of purchase the storage efficiency is the highest, nearly 1. However conventional containers maintain the container volume and shelf space utilization even though the contents are depleted through progressive consumption. In conventional container as the volume of the material contained depletes the storage efficiency falls. When the container is half full the storage efficiency becomes 0.5. Containers built to the concept of space saver container are volume adjustable to shrink in volume to the extent there is free space within the container. Thus the storage efficiency of containers built to this concept are capable of maintaining their storage efficiency of nearly 1 through out the period they contain material, depleted or not. In effect the new containers release space to the shelf Space saver container based milk container would release space to the refrigerator as the milk is consumed. It is possible to stock up on items that are almost over as more and more space becomes available due to combined effect of other containers built to the new concept. The availability of space makes other items in the refrigerator more accessible particularly the ones stored along the back wall. To time a visit to the grocery store precisely when the contents are over is difficult and sometimes impossible. Breakfast without milk becomes a reality. The space saver container's ability to release shelf space as soon as the contents are consumed enables re stocking activity to begin well before the item is totally consumed. Thus space saver container improves accessibility, improves re stocking window and reduces the risk of running out of essential items. The conventional containers in the instance of milk allow on an average a 12-hour window to re stock to have it available for breakfast the next day. This window can be considerably improved with a container built to the concept of space saver container. The disadvantage of fixed volume container storage is eliminated with adaptable volume design of the space saver container. By combining the space saver container concept with standard manufacturing practices a wide variety of storage solutions are possible. The embodiments presented herein address application of the concept to fluids and solid objects as in the case of milk, bottled water and ice cream but it is recognized that the concept can be extended to other material, objects and systems that require efficient space utilization. The ideal is a storage efficiency of 1 even when the volume of the stored entity changes.
- There is prior art under the title of plurality of selectable volumes, which deals with cartons that by virtue of different folds create different volumes. Once assembled, the volume is fixed and the container behaves like a fixed volume container. There was no discovery of prior art on container design that retains adjustability of volume once assembled. The issues of stocking up and accessibility exist because of inability of the currently available containers to adapt their size to the volume of the content of the containers if so required by the consumer.
- The concept of adjusting container volume to match the volume of the content is the basis for the invention referred to as space saver container.
- The concept has been illustrated by applying it to four typical usages. Each application has differences in construction but substantially use the same principle. The differences have been highlighted through four embodiments:
-
Embodiment 1 is the application of the concept to half-gallon container for milk using elastic material to create a container composed of bellow biased for maximum extension. The bellow can be compressed and in the process behaves like a compressed coil spring that is stabilized through a restraint means, which enables the new shape to be stable. The reduction of volume is accompanied by reduction of footprint. In operation the restraint means is a ball chain. One end of the chain is a ball called anchor ball and the other end is a smaller ball called the latch ball. When a reduced volume is desired the user compresses the surfaces and pulls on the latch ball to take up the slack. The appropriate ball in sequence gets latched to hold the new shape of the container. -
Embodiment 2 is the application of the concept to larger heavier containers that need a special handle. Balanced weight distribution becomes a requirement and has been addressed using an elastic material to create a pair of bellows symmetrically placed around the handle as a part of the container enclosure. The restraint means is identical toembodiment 1. Space saving is accompanied by reduction of footprint. -
Embodiment 3 is the application of the concept using a non-elastic material to create container that can collapse by creating folds in the construction material like stiff paper sheets. (A single fold is a particular case of a bellow). The restraint means is different fromembodiment 1 & 2. Space saving is accompanied by reduction of footprint. -
Embodiment 4 is the application of the concept with the volume shrinkage taking places transverse to the ground or the seat of the container. This application shows its adaptation to solids like ice cream containers. Space saving is through reduced container height without change of footprint. - The embodiments are aimed at creating space outside even as the contents are progressively depleted. The FIG. 23 contrasts the front of a refrigerator shelf and an ice box laden with space saver containers on
day 1, when the contents are full, today 4 when it is assumed that more than half the contents are gone. Typically such containers would be loaded with milk, fruit juice, water, yogurt and ice creams. -

Embodiment 2 -
Embodiment 2 has all the elements ofembodiment 1 above which are: tunnel bellows, air tunnel tube, ball chain, anchor and latch restraint means, access to the enclosure for fluid loading and unloading and lid to seal the access. - The differences are that container has a
handle 70 and a pair of bellows symmetrically disposed around the handle. Amain conduit 80 that connects to the pair of tunnel bellows that have sealed ends. - The container volume can be reduced by compressing the two sealed ends of the tunnel towards each other similar to the functionality of
embodiment 1 above. - FIG. 24 is the perspective of
embodiment 2. - FIG. 10 is the elevation of the space
saver container embodiment 2. It has all the elements ofembodiment 1 described above with the addition of handle (70). 74 is the anchor seat for the anchor ball. - FIG. 11 is the elevation of FIG. 10 as seen along a-a.81 and 85 are two tunnel bellows that form wings to the main section of the container that has a fixed
main conduit 80 connected to the tunnel bellows. -

- FIG. 12 is the elevation of the Ball Chain restraint that shows the
Anchor Ball 100 and Latching Balls 101 to 115. - FIG. 13 is the view of FIG. 10 seen along the arrow b-b. This is also the seat of the space saver container on which the space saver container can stand upright. The
elements -
Embodiment 3 - This illustrates the concept of the space saver container by using a single pleat bellow that is formed by creating a fold in a stiff paper sheet. The choice of paper material can provide the natural bias for the container to hold on to the maximum volume or the designed shape and volume of the container.
- FIG. 14 is the perspective of a collapsible container. For ease of viewing and understanding how this design enables the container to reduce in volume the critical lines of fold and angles between edges are labeled.
- Surfaces300 and 301 by application of force directed towards each other can be forced to approach each other causing the structure to fold along lines c1, c2, c3, c4, f1, f2, f3 & f4. This causes the angles t1, t2, t3, t4, t5, t6, t10, t11, t12, t13, t14, t15to reduce thus the volume of the container can be reduced until the
surface 300 touches surface 301 which is when the volume of the container content is nearly zero. - A restraint in the form of a loop ball belt is tightened around the sides as shown in subsequent figures (FIGS. 17, 18).
- FIG. 15 is the side elevation of the restraint means called the ball loop chain that has a loop (305) on one end connected to a chain of balls. The ball diameters are dimensioned to be able to pass through the loop but large enough for the loop to capture them if the chain is under tension. The loop under tension becomes elliptical thereby creating interference with the balls and in the process latching them.
- FIG. 16 is the side elevation of the restraint means with the end ball inserted through the loop of the ball chain.
- FIG. 17 is the plan of the
embodiment 3 with the ball loop chain belted around theembodiment 3 with the ball end latched to the loop of the chain. The ball end can be tightened like a belt to enable any of the reduced volumes to be stable. - FIG. 18 is the elevation of
embodiment 3 with the restraint means looped around it when the container is full. -
Embodiment 4 - This embodiment is presented to show the application of the concept to an ice cream container. The two surfaces that can be compressed towards each other are the
lid 405 and thebottom seat 415 of the container. Thewalls 410 of the container form the tunnel bellow. The contents being frozen allow only the portion of the tunnel bellow free of the frozen material to compress until the lid touches the frozen surface of the contents. The embodiment retains it's foot print but shrinks along the vertical axis. The benefit to this design is the ability to stack items over the package since the container through compression releases space over the structure. The restraint means is obtained by external means through the top surface of the icebox or the stacking weight of other containers placed over it. The design enables the container to be compressed into a tight fit enclosure. If required a restraint means similar toembodiment 3 can be incorporated. - FIG. 19 is the perspective of embodiment. The press fit lid captures the bellow tunnel to seal the contents. The bellow tunnel is biased to attain maximum extension.
- FIG. 20 is the side elevation of
embodiment 4. 405 is the side elevation of the lid that acts as one of the surfaces of the enclosure formed between the bottom seat 415 (the second surface),tunnel bellow 410 and thelid 405. - FIG. 21 is the side elevation of FIG. 20 after the top surface is compressed. The container is shown empty so the bellow is shown compressed uniformly. When the container has frozen ice cream it compresses only in the empty space above the frozen ice cream.
- FIG. 22 is the plan of the lid or405 viewed along the direction e-e in FIG. 20.
