The present invention relates to an injection molded plastic container commonly used for various purposes of storing both food and non-food products, such containers having suitable seals or lids. In particular, the present invention relates to a container in a form that is folded to facilitate storage when the container is empty, rather than a rigid structure as a conventional jar.

Cups, jars and similar containers are well known in the art and take many forms. Among these containers are folding cups or glasses, which, like a telescope, are formed of stacked annular wall portions that slide against each other between a fully open and folded position. Since these wall parts are not formed integrally and slide freely with respect to each other, there is a possibility of significant leakage and it is not practical for use other than temporary beverage containers. Another form of folding container of the present invention is shown in US Pat. No. 5,439,128, issued August 8, 1995 to Fishman. In Fishman's vessel, the wall portion is integrally formed and the wall portion is made up of alternating vertical and inclined portions to form the vessel wall. The wall portions are integrally joined by thin film hinges that, when folded, become the center of rotation when folded. To actually fold the wall parts of the fishman down, the wall parts must be bent for the folding operation. As such, in addition to the film hinges, large central relief grooves are required in each inclined wall portion, at least in some cases, as shown in Figure 3 of the Fishman patent, if the wall portions themselves must actually be bent, These central relief grooves will weaken the wall parts inherently, which is an important problem. It can also be seen that when the fishman's vessel is folded, alternating vertical wall portions of the open vessel maintain a vertical orientation with respect to the bottom wall. If the container is formed by the injection molding in the folded position, there is a commercial advantage because of the large cost saving effect in the mold manufacturing and molding process, since the fishman's container is manufactured by the injection molding method in the folded position. It is obvious that is not suitable.

It is a primary object of the present invention to provide a collapsible container which forms a substantially rigid receptacle in an open or opened position and is snapped into suitable lids or seals to provide a waterproof storage container for, for example, a suitable foodstuff or the like. These containers are very convenient and provide a particularly good way to carry "on-the-go" foods such as picnics, lunches of those who take lunch at work, and other occasions that require disposable storage. The foldability of the container, especially when the lid is installed to hold debris in an empty container, folds approximately completely compact to a minimum height, which is convenient for "yellow envelopes", backpacks, picnic baskets or the like for cleaning and reusing used containers. Are stored or packaged.

 In addition to the main object of the present invention, one object of the present invention is to provide a method of forming a container in a folded position with maximum economy in a mold apparatus and method, and to provide a molded product that is fully expanded to a compact and relatively rigid freestanding position. To provide.

An important feature of the container of the present invention lies in its ability to gradually open one sector at a time, to change its volume, and at the same time maintain its position in any folded position.

Another feature of the present invention is a container which can be washed in the dishwasher in a folded position, as in a conventional dish, can be stacked and stored in the dishwasher, kept open when using the container, and closed when storing the container It is intended to provide a container that remains in a state, and a container that maximizes the available space when stored in a shipping box and at home.

In order to improve and put into practice the container of the present invention, the peripheral wall of the container, which extends between a rigid base and a rigid top ring for receiving a snap-locked closure, comprises wall parts that are rigid annular or circumferentially continuous. The wall portions are joined to wall portions adjacent to, in fixed annular vertex forming connections, the vertex forming connections facing inward and outward alternately. The wall portions have relatively flexible annular portions therebetween. The wall parts are each inclined alternately inward and outward with respect to the interior and vertical lines of the container in the open or open position of the container, and the respective wall parts arranged in order upwards from the base to the upper ring. Its diameter or its circumference gradually grows larger than the base. Thus, the shape formed in the unfolded container becomes a truncated cone that is upside down and the wall portions basically form a step from the base towards the outside outward. Thus, the wall portions can be folded down precisely to form a concentric circle surrounding the base and the upper ring surrounds the folded wall portion.

The act of actually folding the wall parts against one another takes place in a bent part located at the apex part between the wall parts, where the bent part is where each wall part is connected with a wall part directly adjacent thereto, The thickness is thinner than the thickness of the wall portions disposed on both sides. With the container open, the thick wall portions are more rigid than the bent portion and have significantly limited flexibility than the bent portion. In the unfolded state of the container, the thin portion forms a bow-shaped continuum with respect to the thick wall portion and forms an arc of at least 90 degrees, while the container wall is folded over until the thin portion is physically flipped over its center while the container is folded. Provides a considerable degree of stiffness to the wall parts with respect to the overall height of. Applying a physical force to fold the top ring and the base relative to each other, the flexible portions between the wall portions will be bent laterally with respect to the folding direction by the flexible hinge with the curved portion, and this bending A flexible hinge with parts allows the container to be folded and at the same time minimizes the tendency for the wall parts to bend laterally or to move laterally when the wall parts are folded relative to each other. Each curved portion formed by the thin portions is partitioned along its edge by thick wall portions adjacent thereto. Once the arc of the bent portion is reduced to less than 90 degrees and flipped over its center, the resistance to prevent movement of the bent portion is overcome and the folded portion is shaped like a dome of less than 90 degrees. To move from the closed state to the open state or vice versa, each bent portion is slightly twisted or distorted until it overcomes its stable position and is flipped to another position.

In the folded and molded container according to the invention, the facing rigid wall parts are formed by two walls which open in an angle range of 8 ° to 40 ° with respect to the vertical line and generally form a generally triangular gap. However, for reasons to be described later, the preferred angle range is about 10 degrees to 16 degrees.

Unfolding the container in the folded position requires pushing or pulling the base downwards as the top ring moves vertically upwards from the base. When the flexures are deployed to move to form an arc of 90 degrees or more, the wall is fixed and actually holds the container in the open position.

Further features, objects, and advantages of the invention will be apparent from the following description of the invention and its configuration.

In the drawings, reference numerals of the embodiments of Figs. 1 to 11 are denoted by two digits. The code | symbols of the Example of FIG. 12 thru | or 22 are attached | subjected with the same number by adding the numeral 1 in front.

With particular reference to the drawings, the folding vessel 10 has a base 12, an upper ring 14, and a folding wall (container wall) 16 extending therebetween. The base 12 is a substantially rigid member comprising a bottom 18 and an upstanding base wall 20 in the circumferential direction. The base may have a flat shape and the base has a suitable structure, such as a dome, and has a push or ridge 24 extending slightly upwards from the center to aid in the unfolding of the container as described later. The base also has a series of small foot shaping knobs 26 or continuous ball ribs (not shown) attached to the bottom 18.

The upper ring 14 comprises a continuous or annular ring wall 28 and a flange 30 facing outwardly horizontally at approximately intermediate heights on the ring wall 28. The upper ring 14, like the base 12, is substantially rigid and has a non-circular cross-sectional area larger than the base 12 or larger than the base 12, thereby allowing the container to be folded as shown in FIG. Surrounding the base from the outside is sufficient to accommodate the vessel wall folded between the top ring and the base in position. The upper ring flange 30 provides additional lateral stiffness to the upper ring and provides a convenient means for handling the jar, especially when the contents are filled. In addition, the ring flange 30 is a finger on the periphery and the bottom of the flange 30 while the user presses the base dome shaped pressing portion 24 downward with the thumb when trying to deploy the folded jar. By making it easy to fix it, it is possible to forcibly unfold the base and the upper ring with respect to each other. In the case of a particularly large jar, it is not possible to pressurize the pressing part 24, but instead it may press sequentially around the bottom 18 immediately adjacent to the base wall 20 in the circumferential direction. Preferably, as can be seen in Figures 1 and 2, the ring flange 30 protrudes or extends slightly outward from the portions facing each other in the radial direction, thereby forming the grip handle 32.

Forming the base and the upper ring into parts separate from the wall part is a preferred way to allow parts such as the base and the top ring to have substantially greater rigidity than the wall part, in which case the actual folding and folding action Silver occurs by using a polymer having various stiffness or flexibility.

The container side wall 16 consists of a wall portion 34 that is continuous in an annular or circumferential direction, the lowermost portion of which is naturally the wall 20 of the base 12 during a process such as multi-component molding. Closely coupled to the wall of the base, the lowermost part rests on the support shoulder 21 slightly above the bottom of the base.

In the embodiment of Fig. 5a, the lowermost part or lower part is located at a level slightly lower than the rest located thereon, and the lower part or lower part is integrally connected with the thin base part 22 protruding upwards, and when the container is folded, The base part 22 forms a bent part between the base part and the wall part located in the lowest part.

The wall part 34 is located at the top from the part where the lowest part joins to the base part, and the wall part is inclined alternately outward and inward with respect to the direction perpendicular to the interior of the container, and vertices or vertices alternately facing outward and inward. Each part joined with the part located directly above in the part forms an angle joint indicated by reference numerals 36 and 38.

Referring to Figure 5, the best part or top 34 is bent to the color 37, which is received in the lower part of the ring wall 28 and is tightly fixed and directed upwards, in the manner presented in the bottom part above. By part. In the embodiment of FIGS. 5A and 6A, the best part 34 is integrally or securely joined in the circumferential direction to the lower edge of the upper ring 14.

Looking at open containers, each alternating inclined wall portion has a predetermined thickness and has limited flexibility compared to the bent portion 40 joining adjacent wall portions 34. The bent portion 40 is relatively thin compared to the wall portion 34 and is generally the same thickness as the extension 22 of the base of FIG. 5A. The bent portion 40 generally forms an angle joint 36 or 38 between each wall portion and the wall portion adjacent thereto. The height of this thin portion 40 is generally smaller than the height of the wall portion 34. Referring again to Figure 5, in the open or open position of the container, these curved portions 40, with respect to the outwardly inclined wall portion 34, form a continuous surface in the inner surface direction thereof, and tilt inwardly. The photographic wall portion is a continuous surface in the direction of the outer surface of the corresponding wall portion. If so formed, the angle between the thicker wall portions on both sides of this bent portion 40 naturally forms the direction of the folding action, which appears in the folding order shown in FIG. In addition, prior to the folding operation, by placing the bent portions 40 between adjacent portions 34, some degree of overcenter stability is provided, and the phenomenon that the wall 16 is accidentally folded is prevented. To overcome this overcenter stability, a sufficiently large vertical pressure is applied to the upper ring and the base, and the upper ring and the base are pressed vertically with respect to each other so that the bent portions 40 are flipped over their centers. It should cause a "snap action" that causes the flexures to be folded into a folded position. At the beginning of the folding operation, each associated bent portion 40 is slightly distorted until it moves to a position that starts to fold into the folded position, that is, the over center position. In this way, with the contents embedded in the container, the tendency of the container to accidentally close or fold itself is minimized.

As can be seen in the figure, adjacent wall portions 34 in the folded position of the container form opposite V-shaped or triangular openings. The centerline of each V-shaped opening is generally perpendicular to the horizontal plane of the folded container. This structure greatly helps the injection mold to separate and eject the molded product.

The flared angle between adjacent folded portions 34 can range from 8 ° to 40 °, preferably from 10 ° to 16 °. The angle of 10 ° is considered to be optimal for balancing the container stiffness in the open position with the force required to fold or unfold the container. In addition, such an angle is actually considered to be the minimum angle at which the molded product can be constantly discharged from the mold. As is known, increasing this angle reduces the rigidity of the open container.

7 to 9, if necessary, when the container is opened and folded, the wall portion (by rotating the container while sequentially pressing or applying pressure around the container rather than snapping each curved portion all at once) It can be seen that it may be convenient to give a slow moving effect to 34).

9 shows a partially folded or unfolded container, especially when small doses are required. In such a position, the container can sufficiently perform the function of receiving and storing food and the like, and the lid (sealing part) 42 is also provided in that the dimensions of the upper ring are stable at all positions of the container. The same function can be fully performed as in the open container of 3.

Referring to Fig. 3, it can be seen that the shape in which the wall portion is stepped outward in the upward direction from the base portion to the wall portion forms a truncated cone shape in which the container is opened upside down.

Referring again to Figures 7-9, when the container is folded in the vertical direction, the bent portions 40 are folded in a generally dome-like shape between adjacent portions. Thus, adjacent wall parts are folded such that thick major heights of the wall parts are arranged concentrically and generally parallel to each other, and the angle between the adjacent parts is preferably between about 10 ° and 16 °, and Adjacent portions are laterally aligned between the base wall 20 and the upper ring wall 28 and surround the base. This is illustrated in the enlarged detail cross-sectional view of FIG.

Referring to Figures 3, 9 and 10, it can be seen that the seal 42 can be snapped to the upper ring 14 in any suitable manner at any position the container takes. In order to easily fix the seal to the upper ring, the upper part of the upper ring wall 28 located above the circumferential flange 30 is inclined slightly outward so that the upper part of the upper ring wall is positioned on the seal. It can be stored in the peripheral groove to the side. Regardless of where the container is located, as long as the folded wall portions are located concentrically inward with the rigid upper ring 14, the closure 42 is suitable for open, partially open and folded containers. By using the lid, it can be seen that a compact, lightweight storage location can be provided.

As can be seen above, when attempting to open the container before using it, place a finger around the peripheral flange 30 of the upper ring and project upwards from the center of the base bottom 18 with one or both thumbs. What is necessary is to apply a downward pressure to the pressed ridge part 24 of the bottom. Alternatively, pressure may be sequentially applied to the bottom itself around the pressing ridge. Also, referring to Fig. 11, without pressing the pressing portion 24 or the bottom 18 directly, the transverse bar 44 has a concave recess or groove formed by the pressing portion in the lower surface of the bottom 18 in a diagonal direction. It may be provided across. This transverse bar 44 allows the user to grab the finger and pull the vessel base directly, thereby moving the base downward relative to the upper ring to unfold the wall portion.

Referring back to FIG. 6, the lowermost folding wall portion 34 serves as a restriction to prevent the remaining wall portions and the upper ring from folding down the base wall, supporting the wall portions and the upper ring, the base bottom and the support. Keep slightly above the support plane, which is formed by the foot. Thus, when the container is unfolded and folded, the support of the container is present on the base and the foot, rather than on a very thin bend.

12 to 22, the basic parts of the present embodiment are substantially overlapped with the above-described embodiment. Therefore, the reference numeral in this embodiment is displayed by appending the number 1 to the reference numeral in the foregoing embodiment. Thus, the container 110 consists of a base 112, an upper ring 114, and a folding wall 116 of alternating rigid wall portions 134 and curved portions 140.

The container 110 is unfolded and folded in the manner described in the first embodiment, and in the folded position the container is configured such that the container can be shaped practically and preferably in this position. Thus, the wall portions 134 form an opposite V-shaped opening in the folded position, in which case the angle between the wall portions is in the range of 8 ° to 40 °, but preferably 10 ° to 16 °. Range, the optimum value is 10 degrees. Each V-shaped opening has a centerline extending from the vertex formed by the wall portions 134 converging in one place and perpendicular to the horizontal plane of the folded container. In the open or open position of the container the wall portions 134 are at an angle greater than 90 ° with respect to each other and at an angle to a vertical line formed at right angles to the base.

In order to improve the folding and unfolding behavior of the wall portions 134, each wall portion 134 is formed obliquely along its edge, as in reference numeral 135, such that the curved portion 140 adjacent to the wall portion 134. To provide a gentle transitional part in between. This is different from the abrupt transition portion of the first embodiment shown in Figs.

As in the first embodiment, the bent portions 140 form a continuity in their inner surface direction with respect to the wall portion 134 inclined outward in FIG. 16 in the position of the container opening. Similarly, the curved portions 140 form a continuity in the outer surface direction with respect to the inclined wall portion 134. As mentioned earlier, this relationship helps to naturally form the direction of the folding operation shown in FIG. 19 as well as in FIG.

Referring to Figures 16 and 17, it can be seen that the bottom wall portion 134 is formed higher than the wall portion thereon, reaching the full height of the surrounding upstanding base wall 120. The lower end of this lowest wall portion 134 is bent below the bottom 118 of the base 112 and joined into the receiving groove 119, thereby becoming part of the support plane of the container. As can be seen, an increase in the overlapping area between the bottom and the base of the vessel wall facilitates the engagement between the bottom and the base of the vessel wall.

The engagement of the container wall to the top ring is made by the laterally facing color 137 joined to the best wall portion 134 by the best bent portion 140. The collar 137 includes a locking bead 139 facing upward at its outer edge, the collar 137 and the locking bead 139 both having corresponding locks disposed at the base of the annular ring wall 128. It is stored in the main part. The upper ring 114, like the ring 14 described above, includes a ring flange 130 that integrally protrudes outwardly, and provides a side rigidity to the upper ring and a convenient means for manipulating the jar. To facilitate flange gripping, an integral gripping bead 131 is provided around the outer edge of the flange 130.

Variations of the above embodiments are finally shown in FIG. 12 and various cross-sectional views of the container 110. As can be seen by contrasting these figures with those of the first embodiment, the base 112 has a substantially upwardly extending centrally extending press or ridge 124. This in particular increases the area that can be exerted to open the container, making the container easier to handle and at the same time making the flat bottom 118 stronger. As shown in Fig. 22, the lower pressing portion 124 may also be provided with a cross bar 144 in a diagonal direction for the same purpose as mentioned above with respect to the cross bar 44.

Also, as mentioned in the first embodiment, a suitable closure 142 may be provided that can be snapped to the upper ring 114. Such a closure will include a suitable lid for the container, whether in view of how the container is folded and unfolded so that the folding walls are concentric, whether the container is fully open, fully folded or partially unfolded. .

Specifically, referring to Fig. 21, the wall portion 134 folded downward and in particular the downwardly curved portion 140 are held slightly above the support plane formed by the base bottom and / or the support feet, thus providing a more stable support. It can be seen that and provide a substantially thin bent portion does not engage the support surface.

The above mentioned container is designed in a configuration using a "network" of bent parts. This is not an accordion form that opens and folds like a spring. In contrast, flat containers serve to fold and fold based on the principle of "counter".

In known spreading containers, the container is generally molded in an open or unfolded state. Thus, the natural state of these containers is an open state. That is, these containers will tend to be more open than any other location. Thus, if one wishes to fold or unfold these containers, they will repel to remain open (ie, try to return to their natural state). This is not the case for containers of the invention that are molded in a flat or folded state. That is, the natural state of the container of the present invention means that it is intended to remain closed from the beginning. There are many folded parts in the network of bends. In the illustrated embodiment, three sets are provided that operate independently of each other (additional sets may be added if necessary to further increase the number of cases of variable capacity). As shown in Fig. 9, each independently actuated curved portion has a second "natural" state, i.e. a resting state, when open, in which the particular folded portion It will try to stay open regardless of the rest of this other fold. In the present invention, in the folding operation and the opening operation of the container, the folded portions must be operated independently of each other. Active operation is required to fold and unfold the container. This can be called the principle of "opposite". The angle of the folded portion in the closed position keeps the folded portion in a closed state, and the angle of the folded portion in the open position keeps the folded portion in an open state. In order to move from the closed state to the open state or vice versa, the bent portion is slightly twisted and distorted until it overcomes this opposition and is flipped to another position. This operation is because the diameter of the bent portions does not change. There is no intermediate position for the folded portion. The folded portion is either open, folded, or twisted (one open and the other closed). For example, in such a structure, it is impossible for each part to be half-open while maintaining the use capacity. As mentioned earlier, one way to easily adjust the bends is to move the container 'slowly' one side at a time, in a partially or fully open position.

The folding container of the present invention has been described in a preferred embodiment as having a "separate member" comprising molded plastic, such as, for example, a resin polymer, and comprising a base, an upper ring and a folding wall. For example, in a preferred molding method the "separate member" is realized by using a molding apparatus capable of shaping the base, the upper ring and the folding wall in a plurality of steps, in which the molding apparatus is considerably high and / or ordinary Polymers with varying stiffness can be selected. It can also vary the color and clarity of the base, top ring and folding wall.

As mentioned in connection with the embodiment of Figures 5A and 6A, it can be seen that the container of the present invention can be molded into a single structure essentially in a single molding process. In addition, the difference in the relative stiffness of the base and the ring to the folding wall, which was mentioned above as preferred, that is to make the base and the ring a normal stiffness, but more flexible than the folding wall, can be achieved by selecting some parts to a suitable thickness. It can be made in one molding process. It is also possible to provide a molding apparatus in which a polymer having various stiffness or flexibility to be formed at the base, the top ring and the wall is provided at a specific portion inside the mold.

Molds suitable for injection molding the wall part in the folded position, supported by the mold halves, have the same number of concentric annular shapes in the number of wall parts being folded together and have a triangular shape with finger fingers or V It can be seen that mold elements having a magnetic shape are required.

It is contemplated that what has been said above is intended to explain the principles of the invention. Since modifications and variations of the above can occur to those skilled in the art, it is not desirable for the invention to be limited to the configurations and methods of use shown and described above. Rather, it will be appreciated that all suitable modifications and equivalents fall within the claims of the present invention.

The inherent configuration of the present invention is that the container remains flat in the closed or folded position, and opened in the open or partially open position. Since the state of the bent part is made up of two "natural" states, the container tries to remain closed when it is folded flat, and open when it is open. As the bent portions in the network are each operated independently, the container can be opened at a constant partial dose because the container is intended to remain partially open. This is of particular value in maximizing and optimizing the storage space as in refrigerators and the space of the dishwasher during cleaning.
