Abstract
ABSTRACT
A squeeze-outable container with a hollow space for, eg., pasty, powdery or liquid goods is formed out of a single blank, which is bent over in a somewhat U shape. The blank consists thereby out of a bendable, mainly stiff, carton-like or carton con-taining material or also out of carton itself. The edge areas of the blank lie flat upon one another after the forming procedure and are then tightly joined. Only in the area of the crossover of one wall to another a U cross ridge is produced across the base, which exerts a distancing function on the hollow space of the container. An at first flat channel passage is provided in the edge area of the container beyond the base, in whose area the edges of the blank are not joined together.
This channel is closed before use and can be opened by tearing or cutting off a tongue into which it leads.

Description
12~9~1 BA~KGROUND 0~ ~HE ]NVEN~]ON
~his invention relates generally to containers such as tubes, pouches and packets for holding and dispensing various types of flowable substances or materia1s such as pastes, liquids or powders and more particularly to containers made from stiff deformable flat unitary blanks which when folded on themselves form a self-sustaining container with a cavity therein so that initally it can be charged with the filler substance or material and then sealed it is necessary to dispense the same from the container.
Compressible or squeezeable containers are well known and more commonly are made of, metal. These containers are expensive and require various surface preparations to make the inner surface inert to the filler substances or materials charged into such container. Additionally, this type of container or tube often requires a closure assembly generally at one end which adds to the cost of the materials and therefore the cost of manufacture of such tubes.
Plastic tubes for holding and dispensing flowable substances or filler materials are also well known and are generally similar in construction to these metal t containers and tubes.
Squeezeable and disposable containers for holding flowable substances or filler materials for one time use are also well known in the art. Usually they consist of a sealed plastic foil material which takes on a pillow like, bulging, shape when filled with the flowable substance or 30 material to be dispensed. These disposable containers are generally torn open or cut on an edge to form the f discharge opening. If the total amount of the filler material is not used, the rest of the filler material r ~ ~
C
lZ~961 cannot be stored as it will either run out, dry up or evaporate since the container itself cannot retain the goods due to its softness and lack of a closure means.
Therefore the user of such disposable containers must 5 either use all of the flowable substance or filler materi al or waste the remainder in the container.
Prior art containers or tubes as above described are disclosed in U.S. Patents 2,432,462; 2,947,653; 3,338,475 and in British Patent No. 548,474.
1O The present invention provides an inexpensive squeezable and disposable container with a self-activating closure means. The container does not have to be completely emptied after opening the same because the structure of the container acts to retain the balance of flowable 15 substance or material therein after it is opened without the need of a cap or the like type of closure device.
The present container overcomes the problems of the prior art by having on at least one of its sealed edges a sealable throughput or outlet passage which communicates 20 at its inner end with the space for the flowable substance or materi al to be dispensed from the container. The end of the throughput or outlet passage remote from the inner end lies in a dispensing means or tongue a segment of which can be torn or cut off to form an opening when it is 25 desired to dispense material from the container. By reason of the material and the construction of the containers in accordance with the present invention, the walls of the tongue through which the output passage extends are normally disposed in a flattened state and 30 resist separation from each other due to the self-acting compressive forces inherent in the stiff deformable material from which the container is made. The outlet passage in the dispensing means or tongue therefore remains closed even after the tongue is torn or cut off to f~
~ .
, .
lZ~)961 form an opening for the throughput or outlet passage and the container i5 substantially self-sealing after a portion of the flowable substance or material is discharged from the container.
Further the squeezable container as above described can be hermetically sealed, shipped and stored until the user tears or cuts off the dispensing means or tongue to form an opening for dispensing the flowable substance or material therefrom. Due to the self closing or ; 10 self-sealing characteristics of the material from which the container is made the flowable substances or materials stored in the container are substantially protected against accidental or unintentional discharge from the container.
The bottom of the container is shaped and located between the side sections so that it provides a generally stable shape for the container such that the flowable substance or material in the container does not readily escape therefrom even after the container is opened. This eliminates the needfor a sc~ew cap or similar structure as has heretofore been used in the known prior art devices of this type.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings FIGURE 1 shows a generally unitary blank 1 of flat sized and shaped stiff deformable carton material or carton type material or a coated material of the carton type which is more fully described C
1241~91 below, and is used to form the container generally designated
2 in accordance with the present invention. This container will have a stable generally formed shape which will not materially bulge under the pressures exerted by the flowable substances or materials which are charged into the container and are dispensed therefrom under manual or other pressure forces.
The generally unitary shaped and sized flat blank 1 shown in FIGURE 1 will when folded onto itself define the squeezeable and disposable container 2 as shown in FIGURES 1 and 2 of the drawings.
It will be understood by those skilled in the art that the blank 1 is only intended to be illustrative of the principles by which the structure and function of the squeezeable and disposable containers in accordance with the present invention are achieved. Other generally unitary flat sized and shaped blanks of carton material are provided to form squeezeable and disposable containers in accordance with the embodiments of the invention having shapes and sizes which differ from those shown in FIGURES 2 and 3. These additional embodiments are illustrated in FIGURES 4, 5, 6, 8, 9, 11, 12, 13 and 14 of the drawings. Therefore, the additional embodiments as hereinafter described will all have the same character numeral references for the parts and elements thereof because, in principle, they are constructed similar to the form of the invention shown in FIGURES 1, 2 and 3.
The generally unitary flat sized and shaped blank 1 is characterized by a peripheral or circumferentially disposed connecting side flange 6 therearound. Thus, when the blank 1 is folded on itself or bent in a U-shape about the medial area defined by transverse lines indicated by the dotted lines 3a-3b, mutually opposed side flanges can be adhered or sealed C
1;~4~61 together to provide the squeeæeable and disposable container generally designated 2 in accordance with the present invention.
In order to obtain the desired shape or configuration, for example as shown in FIGURES 2 and 3 of the drawings, the blank 1 will be provided with a central section 3 which is disposed so that the transverse lines 3a-3b are located in the medial section thereof and the shape and size of the central section 3 is defined by the fold lines 3a and 3b respectively disposed a spaced distance and on opposite sides of the central portion 3.
Further, blank 1 is provided with a first side wall 4a and a second side wall 4b respectively disposed on opposite sides of the central portion of section 3 so that one respective end thereof is continuous with the associated fold lines 3a or 3b as may be the case for each given side wall.
The side walls or portions 4a and 4b have depressions res-pectively formed therein between the peripheral connecting flanges 6 along the side edges of the respective side wall The side walls 4a and 4b are operatively associated with the central sections 3 so that when the blank 1 is folded on itself and the mating edges of the connecting flanges 6 adhered or sealed the central section 3 forms a base and together they define a storage chamber or cavity 4 for the flowable substances or materials to be held and dispensed from the squeezeable and disposable container 1, all of which is shown by FIGURES 1, 2 and 3 of the drawings.
Those skilled in the art will readily recognize that in order for the container to act as a dispenser of the flowable material, that the same must be charged into the container 1. Therefcre before the mating edge of the entire peripheral connecting flanges are sealed, one 13 12~96~
seCtion thereof will be held open to permit the flowable substance or material to be charged into the storage chamber 4 of the container, and thereafter this open section will be sealed to place the container in condition for dispensing the flowable material therefrom in the manner now to be described.
In the present invention in order to dispense the material from the container 1 a suitable dispensing means or dis-pensing tongue generally designated 7 is provided. Dis-pensing means or tongue 7 having dispenser walls borderedby tongue flanges and forms a discharge outlet 8 which is in communication, by virtue of a dispensing passage, at one end with the storage chamber 4 and which can be opened for dispensing purposes by separating or tearing the end or severable sealing flange of the dispensing means or tongue 7. The dispensing means 7 is further characterized by the fact that the discharge outlet 8 is normally closed and will be self closing or nearly automatically self-sealing due to the materials from which the containers are made and by reason of the release of the compressive forces used in dispensing the material from the storage chamber 4.
Thus remote from the transverse fold lines 3a and 3b and central section 3, blank 1 is provided with matching or shaped ends as at 9a and 9b so that when the blank 1 is folded on itself the dispensing means or tongue 7 is formed for the container 1 which are also sealed when the peripheral connecting flanges 6 are adhered or bonded together. However as is clear from FIGURES 1, 2 and 3, the peripheral connecting flanges 6 and the shaped ends 9a and ~ are so formed that there is defined the discharge outlet 8 which communicates at the inlet end with the storage chamber 4 but is sealed at the end opposite there-: from so long as the dispensing means or tongue 7 remains intact and a portion thereof is not torn or separated from the outlet or discharge end of the dispensing means or tongue 7.
C
lZ4S,1961 1;
In the illustrated embodiments in accorance with FIGURES2, 3 and 4 and to a certain extent also in FIGURE 5, the dispensing means or tongue 7 with the normally closed discharge outlet 8 is disposed opposite or remote from the bottom section 3.
In FIGURES 6 and 7, the dispensing means or tongue 7 with the discharge outlet or opening 8 is provided on a side edge adjacent to the shaped bottom 3. At this location as shown in FIGURE 7 and, the angular space or transition area 10 is sufficiently strong that the self-sealing characteristics of containers in accordance with the present invention is very pronounced. In this form of the invention the container 1 is discharged by squeezing from the flatter or thinner section remote from the shaped bottom 3 to the wider or thicker section thereof.
In the illustrated embodiments in accordance with FIGURES
2 to 8 of the drawings the width of the surrounding edge or flange 7 about the discharge outlet 8 is about the same ~as the edge or flange 6 about the remainder of the container which is advantageous for manufacturing purposes.
In the embodiment of FIGURE 9, the peripheral flange or side edge 9c has a greater width in the area of the discharge outlet 8 because the total blank width selected is uniform in this area thus generating a simpler torm of the blank I for this form of the invention.
The dispensing means or tongue 7 may be provided with one or a plurality of tear off aids for example as shown by the oppositely disposed notches at 12-12 in the peripheral flanges or side edges 9a and 9b. Notches 12 when disposed in an area which is generally rectangular with respect to the discharge outlet 8 can be formed with two notches C L.
1;
~z~?961 t Jisposed on opposite sides with respect to each other.
This construction is desirable because it enables the dispensing means or tongue 7 to be unsealed, by tearing off or cutting off a portion in a generally straight line.
Further the user can tear or cut off this portion of the dispensing means or tongue 7 from either side of the discharge outlet 8. The peripheral flanges or side edges 9a-9b which are a continuation of the flanges 6 about the remaining portion of the container 1 act to maintain the dispensing means or tongue 7 in a flat engaged and sealed position so as to seal the discharge outlet 8 even after a portion of the dispensing means or tongue 7 is removed.
Another modified embodiment of the invention is shown in FIGURE 8 wherein the discharge outlet 8 which penetrates the peripheral flanges or side edges 6 of container 1 will have a relatively large rectangular inlet opening at the end which communicates with the chamber 4 in the container 1 and will taper therefrom to the discharge end of the discharge outlet 8. This tapering design of the discharge outlet 8 could natura11y be provided in all of the other illustrated embodiments of the invention as will be understood by those skilled in the art.
,, .
The dispensing means or tongue 7 which forms the discharge outlet 8 will by reason of this structure have a generally triangular cross-section whereby one triangular side is continuous with the peripheral edge 6 of the container 1 so as to form the angular transition 10, a second triangular side is formed by an edge continuous with and flush with the bottom 3 and a third triangular side is formed by an oblique edge. This triangular arrangement can of course be reversed or a more acute angle established as may be desirable for dispensing materials from the space 4 in the container 1.
'~.
C ~' - ~2~ 6~
FlGURE 6 for example shows that one side of the dispensing means or tongue 7 can be rectangular in plan view and flush with the adjacent side of the bottom 3 similar to the form of the invention shown in FIGURE 8. The effect of this construction is that the corresponding discharge outlet 8 is disposed in an area wherein the angle between the side walls 4a-4b and the peripheral flanges or side edges 6 of the container or ~he flanges about the discharge outlet 8 is at an angle which provides particularly strong and effective self closing forces for the section of the dispensing means or tongue 7 defining the discharge outlet 8 in these forms of the invention.
;, FIGURE 3 further shows that where the bottom section 3 is unitarily connected with the side walls 4a-4b of the container that it has an oval shape and is indented with respect to the peripheral flanges or side edges 6.
However the effect of this construction is that the shape of the container 1 from the bottom section 3 into thè side wall is substantially rectangular in plan view and the center line for the container which extends through the bottom 3 parallel to the peripheral flanges or side edges 6 is a straight line. In this manner, a relatively stable bottom section 3 is obtained and maintained during the use of the container l, for example when the contents are squeezed from the storage chamber 4 defined by the bottom section 3 and side walls 4a-4b of the container.
However, because of the type of material from which the container is made it is possible to empty the container completely by merely exerting sufficient force to destroy the shaped bottom area 3.
A plurality of notches as at 12a, 12b and 12c as shown in FIGURE 8 can be disposed successively along the dispensing means or tongue 7 in the discharge direction of the C. ` , ~:
` ~ 17 discharge outlet 8. This is particularly illustrated in FIGURE 8 where the discharge outlet 8 is tapered in cross-section. This taper discharge outlet 8 permits the user of the container to modify the cross-sectional area of the discharge outlet 8 as may be required or may be desirable for dispensing the flowable substance or material to be dispensed from the container 1. Where the discharge outlet 8 is not tapered but a plurality of notches 12 are provided, the user of the container by tearing or cutting off the notched sections 12 progressively will be able to provide a larger or a smaller dispensing and sealing area as may be desirable depending upon the flowable substance or material being dispensed from the contàiner.
Thus, when the container 1 as illustrated at FIGURE 8 is full the notched section 12a furthest from the space or chamber 4 would first be used so as to provide a longer longitudinal sealing area for the dispensing means or tongue 7 which defines the discharge outlet 8. Thereafter as the materials are discharged from the container 1, the longitudinal extent of the sealing area can be shortened by tearing off or cutting off the next notched sections 12b and 12c respectively as may be desirable or necessary in the use of the container.
~'' .
Thus, collectively a container 1 has been illustrated i which as shown by the blank 1 in FIGURE 1 is simple in construction, does not require a particular closure device as in the prior art devices made from metal or plastic, and which still can be either a single use disposable container or a container which permits the contents to be dispensed in a plurality of dispensing steps or portions of the flowable material as may be required.
A container of this type is particularly adapted to contain cosmetics, for exampie a hair washing agent which :~

-` ~2~ 61 is iniermittently used by dispensing a first portion and later dispensing a second or a third portion. In the prior art containers consisting of plastic foil this ty~e of multiple dispensing is difficult to achieve if it can be achieved at all. Another use for a container of this type is its adaptability for storing and dispensing mustard, ketchup, mayonnaise, etc.
The improved des-ign of a squeezeable container in accordance with the present invention is made particularly clear by the enlarged cross-section at FIGURE 10 of the drawings. FIGURE 10 shows that the dispensing means or tongue 7 is formed by coacting walls 9a and 9b which by , reason of the material and construction of the container 1 are disposed so that the inner walls are in tight superimposed engagement with each other particularly adjacent the outermost end. The dispensing outlet 8 is shown as initially sealed except adjacent a portion of the end thereof in communication with the space or chamber 4 for the material to be dispensed as at the Y-shaped ar,ea 8a which is formed by the walls 9a-9b. This area on the walls of the container is the transitional section 10 between the walls 9a and 9b of the dispensing means or tongue 7 and the side walls 4a and 4b of the container which define the space or chamber 4. The material of the container and this design create a sufficient compression between the walls 9a and 9b so as to provide the required forces for maintaining the dispensing means or tongue 7 normally closed and also to serve provide the inherent self closing effect after a portion of the material stored in the space or chamber 4 is squeezed through the dispensing outlet 8 from the container 1.
lt will be understood by those skilled in the art that the dispensing means 7 could also be connected to the container 1 at a corner, for example opposite the bottom section 3 as is indicated by the broken lines identified as 7a in FIGURE 5.

FIGUR S 11 and 12 show a further embodiment of the inventior~ wherein the bottom section 3 or the corresponding center section of the blank 1 has a multi cornered shape~ for example a hexagonal shape which is particularly illustrated in the perspective embodiment of container 1 in FIGURE 12.
FIGURES 11 and 12 further show that the bottom 3 has side portions as at 11a and 11b which are triangularly shaped one side being continuous with the peripheral flanges or side edges 6 of the container and the other side remote therefrom being in proximity with one of the sides of the connecting bottom portion llc which is rectangular. This construction permits the container 1 to be rested on a rod like support by reason of the rectangular bottom area llc.
One further embodiment of the invention is illustrated in F 1 GURES 13 and 14.
FIGURE 13 and 14 in plan view and partial perspective çross-sectional view respectively show the dispensing means or tongue 7 with the discharge outlet 8 so that the superimposed wa11s 9a and 9b on opposite sides of the discharge outlet 8 are creased or rippled so as to provide transverse convolutions as at 12a and 12b on the dispensing means or tongue 7.
FIGURE 14 particularly illustrates the wave shaped or convoluted profile of these transverse creases and this construction is particularly desirable because it provides improved sealing of the discharge outlet 8 after the normally closed dispensing means or tongue 7 is opened by tearing or cutting the notches 12 so as to open the : discharge outlet 8 formed by the dispensing means or tongue 7.
The generally unitary shaped and sized flat blank 1 shown in FIGURE 1 will when folded onto itself define the squeezeable and disposable container 2 as shown in FIGURES 1 and 2 of the drawings.
It will be understood by those skilled in the art that the blank 1 is only intended to be illustrative of the principles by which the structure and function of the squeezeable and disposable containers in accordance with the present invention are achieved. Other generally unitary flat sized and shaped blanks of carton material are provided to form squeezeable and disposable containers in accordance with the embodiments of the invention having shapes and sizes which differ from those shown in FIGURES 2 and 3. These additional embodiments are illustrated in FIGURES 4, 5, 6, 8, 9, 11, 12, 13 and 14 of the drawings. Therefore, the additional embodiments as hereinafter described will all have the same character numeral references for the parts and elements thereof because, in principle, they are constructed similar to the form of the invention shown in FIGURES 1, 2 and 3.
The generally unitary flat sized and shaped blank 1 is characterized by a peripheral or circumferentially disposed connecting side flange 6 therearound. Thus, when the blank 1 is folded on itself or bent in a U-shape about the medial area defined by transverse lines indicated by the dotted lines 3a-3b, mutually opposed side flanges can be adhered or sealed C
1;~4~61 together to provide the squeeæeable and disposable container generally designated 2 in accordance with the present invention.
In order to obtain the desired shape or configuration, for example as shown in FIGURES 2 and 3 of the drawings, the blank 1 will be provided with a central section 3 which is disposed so that the transverse lines 3a-3b are located in the medial section thereof and the shape and size of the central section 3 is defined by the fold lines 3a and 3b respectively disposed a spaced distance and on opposite sides of the central portion 3.
Further, blank 1 is provided with a first side wall 4a and a second side wall 4b respectively disposed on opposite sides of the central portion of section 3 so that one respective end thereof is continuous with the associated fold lines 3a or 3b as may be the case for each given side wall.
The side walls or portions 4a and 4b have depressions res-pectively formed therein between the peripheral connecting flanges 6 along the side edges of the respective side wall The side walls 4a and 4b are operatively associated with the central sections 3 so that when the blank 1 is folded on itself and the mating edges of the connecting flanges 6 adhered or sealed the central section 3 forms a base and together they define a storage chamber or cavity 4 for the flowable substances or materials to be held and dispensed from the squeezeable and disposable container 1, all of which is shown by FIGURES 1, 2 and 3 of the drawings.
Those skilled in the art will readily recognize that in order for the container to act as a dispenser of the flowable material, that the same must be charged into the container 1. Therefcre before the mating edge of the entire peripheral connecting flanges are sealed, one 13 12~96~
seCtion thereof will be held open to permit the flowable substance or material to be charged into the storage chamber 4 of the container, and thereafter this open section will be sealed to place the container in condition for dispensing the flowable material therefrom in the manner now to be described.
In the present invention in order to dispense the material from the container 1 a suitable dispensing means or dis-pensing tongue generally designated 7 is provided. Dis-pensing means or tongue 7 having dispenser walls borderedby tongue flanges and forms a discharge outlet 8 which is in communication, by virtue of a dispensing passage, at one end with the storage chamber 4 and which can be opened for dispensing purposes by separating or tearing the end or severable sealing flange of the dispensing means or tongue 7. The dispensing means 7 is further characterized by the fact that the discharge outlet 8 is normally closed and will be self closing or nearly automatically self-sealing due to the materials from which the containers are made and by reason of the release of the compressive forces used in dispensing the material from the storage chamber 4.
Thus remote from the transverse fold lines 3a and 3b and central section 3, blank 1 is provided with matching or shaped ends as at 9a and 9b so that when the blank 1 is folded on itself the dispensing means or tongue 7 is formed for the container 1 which are also sealed when the peripheral connecting flanges 6 are adhered or bonded together. However as is clear from FIGURES 1, 2 and 3, the peripheral connecting flanges 6 and the shaped ends 9a and ~ are so formed that there is defined the discharge outlet 8 which communicates at the inlet end with the storage chamber 4 but is sealed at the end opposite there-: from so long as the dispensing means or tongue 7 remains intact and a portion thereof is not torn or separated from the outlet or discharge end of the dispensing means or tongue 7.
C
lZ4S,1961 1;
In the illustrated embodiments in accorance with FIGURES2, 3 and 4 and to a certain extent also in FIGURE 5, the dispensing means or tongue 7 with the normally closed discharge outlet 8 is disposed opposite or remote from the bottom section 3.
In FIGURES 6 and 7, the dispensing means or tongue 7 with the discharge outlet or opening 8 is provided on a side edge adjacent to the shaped bottom 3. At this location as shown in FIGURE 7 and, the angular space or transition area 10 is sufficiently strong that the self-sealing characteristics of containers in accordance with the present invention is very pronounced. In this form of the invention the container 1 is discharged by squeezing from the flatter or thinner section remote from the shaped bottom 3 to the wider or thicker section thereof.
In the illustrated embodiments in accordance with FIGURES
2 to 8 of the drawings the width of the surrounding edge or flange 7 about the discharge outlet 8 is about the same ~as the edge or flange 6 about the remainder of the container which is advantageous for manufacturing purposes.
In the embodiment of FIGURE 9, the peripheral flange or side edge 9c has a greater width in the area of the discharge outlet 8 because the total blank width selected is uniform in this area thus generating a simpler torm of the blank I for this form of the invention.
The dispensing means or tongue 7 may be provided with one or a plurality of tear off aids for example as shown by the oppositely disposed notches at 12-12 in the peripheral flanges or side edges 9a and 9b. Notches 12 when disposed in an area which is generally rectangular with respect to the discharge outlet 8 can be formed with two notches C L.
1;
~z~?961 t Jisposed on opposite sides with respect to each other.
This construction is desirable because it enables the dispensing means or tongue 7 to be unsealed, by tearing off or cutting off a portion in a generally straight line.
Further the user can tear or cut off this portion of the dispensing means or tongue 7 from either side of the discharge outlet 8. The peripheral flanges or side edges 9a-9b which are a continuation of the flanges 6 about the remaining portion of the container 1 act to maintain the dispensing means or tongue 7 in a flat engaged and sealed position so as to seal the discharge outlet 8 even after a portion of the dispensing means or tongue 7 is removed.
Another modified embodiment of the invention is shown in FIGURE 8 wherein the discharge outlet 8 which penetrates the peripheral flanges or side edges 6 of container 1 will have a relatively large rectangular inlet opening at the end which communicates with the chamber 4 in the container 1 and will taper therefrom to the discharge end of the discharge outlet 8. This tapering design of the discharge outlet 8 could natura11y be provided in all of the other illustrated embodiments of the invention as will be understood by those skilled in the art.
,, .
The dispensing means or tongue 7 which forms the discharge outlet 8 will by reason of this structure have a generally triangular cross-section whereby one triangular side is continuous with the peripheral edge 6 of the container 1 so as to form the angular transition 10, a second triangular side is formed by an edge continuous with and flush with the bottom 3 and a third triangular side is formed by an oblique edge. This triangular arrangement can of course be reversed or a more acute angle established as may be desirable for dispensing materials from the space 4 in the container 1.

C ~' - ~2~ 6~
FlGURE 6 for example shows that one side of the dispensing means or tongue 7 can be rectangular in plan view and flush with the adjacent side of the bottom 3 similar to the form of the invention shown in FIGURE 8. The effect of this construction is that the corresponding discharge outlet 8 is disposed in an area wherein the angle between the side walls 4a-4b and the peripheral flanges or side edges 6 of the container or ~he flanges about the discharge outlet 8 is at an angle which provides particularly strong and effective self closing forces for the section of the dispensing means or tongue 7 defining the discharge outlet 8 in these forms of the invention.
;, FIGURE 3 further shows that where the bottom section 3 is unitarily connected with the side walls 4a-4b of the container that it has an oval shape and is indented with respect to the peripheral flanges or side edges 6.
However the effect of this construction is that the shape of the container 1 from the bottom section 3 into thè side wall is substantially rectangular in plan view and the center line for the container which extends through the bottom 3 parallel to the peripheral flanges or side edges 6 is a straight line. In this manner, a relatively stable bottom section 3 is obtained and maintained during the use of the container l, for example when the contents are squeezed from the storage chamber 4 defined by the bottom section 3 and side walls 4a-4b of the container.
However, because of the type of material from which the container is made it is possible to empty the container completely by merely exerting sufficient force to destroy the shaped bottom area 3.
A plurality of notches as at 12a, 12b and 12c as shown in FIGURE 8 can be disposed successively along the dispensing means or tongue 7 in the discharge direction of the C. ` , ~:
` ~ 17 discharge outlet 8. This is particularly illustrated in FIGURE 8 where the discharge outlet 8 is tapered in cross-section. This taper discharge outlet 8 permits the user of the container to modify the cross-sectional area of the discharge outlet 8 as may be required or may be desirable for dispensing the flowable substance or material to be dispensed from the container 1. Where the discharge outlet 8 is not tapered but a plurality of notches 12 are provided, the user of the container by tearing or cutting off the notched sections 12 progressively will be able to provide a larger or a smaller dispensing and sealing area as may be desirable depending upon the flowable substance or material being dispensed from the contàiner.
Thus, when the container 1 as illustrated at FIGURE 8 is full the notched section 12a furthest from the space or chamber 4 would first be used so as to provide a longer longitudinal sealing area for the dispensing means or tongue 7 which defines the discharge outlet 8. Thereafter as the materials are discharged from the container 1, the longitudinal extent of the sealing area can be shortened by tearing off or cutting off the next notched sections 12b and 12c respectively as may be desirable or necessary in the use of the container.

The improved des-ign of a squeezeable container in accordance with the present invention is made particularly clear by the enlarged cross-section at FIGURE 10 of the drawings. FIGURE 10 shows that the dispensing means or tongue 7 is formed by coacting walls 9a and 9b which by , reason of the material and construction of the container 1 are disposed so that the inner walls are in tight superimposed engagement with each other particularly adjacent the outermost end. The dispensing outlet 8 is shown as initially sealed except adjacent a portion of the end thereof in communication with the space or chamber 4 for the material to be dispensed as at the Y-shaped ar,ea 8a which is formed by the walls 9a-9b.

lt will be understood by those skilled in the art that the dispensing means 7 could also be connected to the container 1 at a corner, for example opposite the bottom section 3 as is indicated by the broken lines identified as 7a in FIGURE 5.

FIGURES 11 and 12 further show that the bottom 3 has side portions as at 11a and 11b which are triangularly shaped one side being continuous with the peripheral flanges or side edges 6 of the container and the other side remote therefrom being in proximity with one of the sides of the connecting bottom portion llc which is rectangular.

FIGURE 14 particularly illustrates the wave shaped or convoluted profile of these transverse creases and this construction is particularly desirable because it provides improved sealing of the discharge outlet 8 after the normally closed dispensing means or tongue 7 is opened by tearing or cutting the notches 12 so as to open the : discharge outlet 8 formed by the dispensing means or tongue 7.
