Description

 AUTOMATIC CONTAINER OPENING DEVICE

 PROVIDED FOR MEDIA FOR BREAKING OF CONTAINER SEALING ELEMENT

FIELD OF INVENTION

 The present invention relates to a device for automatic container opening, the device comprising a mouthpiece, a cap and means for breaking the sealing member of a container, which may be the aluminum layer of an aseptic carton, a sealing element installed below the nozzle or the plastic material of a plastic bag package or the like.

 RELATED TECHNIQUE

 [002] It is well known to use containers for storing products such as food seasonings, soups, liquid or pasty products, medicines, cosmetics and other products. Often such containers are provided with nozzles which allow the product to be withdrawn from the container. Such nozzles may be part of the container itself or, alternatively, may be part of container opening devices such as aseptic carton packs or plastic pouch packages, known by the English expression "stand-up pouch".

 Often aseptic carton packs are marketed with automatic container opening devices whereby unscrewing the lid is the only operation necessary for the sealing member of the container to be broken and the contents of the package to be served through the container. nozzle.

 In the case of such aseptic carton packs the sealing element is formed of the aluminum layer of the multilayer material in which these packs are manufactured. In the manufacturing phase of this multilayer material, a hole is drilled in the carton layer before lamination of the other layers, which comprise an aluminum film and layers of plastic material. After the package is formed and the product is properly packaged, and the package is closed, the aluminum layer will be exposed in the region where the hole in the carton layer is made.

 This is where a device for automatically opening the package by gluing or welding will be applied. Usually such a device is provided with a flange whose lower region is substantially flat which will facilitate gluing or welding of the device to the packaging material. In this process the imaginary axis of the nozzle of the device is substantially coincident with the imaginary axis of the hole in the carton paper layer of the packaging material. When the lid of the automatic container opening device is first turned, this will cause the aluminum layer to be cut off, and the package will be opened, its contents can be served through the nozzle.

Various models of devices for automatic opening of aseptic carton packs are known. For example, the device disclosed in WQ2016082008, which comprises using a thread provided with opposing orientation shafts to provide cutting of the aluminum layer of an aseptic carton.

 The present invention relates to devices for automatic opening of containers which may be applied to an aseptic carton pack, a sealing member installed below the nozzle or the plastic material of a plastic pouch pack or the like, as will be readily appreciated by detailed description of the invention to be given below.

 Figures 1A, 1B, 2, 3 and 4 depict a device for automatic container opening 90 in accordance with the present embodiment of the invention. As can be seen from the Figures, the automatic container opening device 90 comprises a lid 89, a mouthpiece 94 and a locking device 96. In the figures the lid 89 is pictured in section.

The nozzle 94, shown in more detail in Figure 1B, comprises a hollow cylindrical body whose outer surface is provided with at least one outer thread segment 95, in the Figures three outer thread segments 95 being shown by way of example only. exemplification, not limiting. The upper region of the hollow cylindrical body of the nozzle 94 is provided with an upper ring 94a located near the edge. hollow body of the nozzle 94, with a spacing between the upper region of the upper ring 94a and the upper edge of the nozzle 94.

 The lower edge of the nozzle 94 is affixed to the upper region of a locking ring 97, the lower region of which is affixed to the upper region of a base member 98, which comprises a hollow cylindrical body whose inner diameter must be larger or smaller. at least identical to the inside diameter of the nozzle 94. The lower region of the base member 98 is affixed to the upper region of a flange 99 which is provided with a hole whose diameter must be greater than or at least equal to the internal diameter of the flange member. base 98, to which it is connected. The imaginary geometric axes of the base element 98 and the hole of the base element 99 are coincident.

 Each outer thread segment 95 comprises two fillets, upper and lower. As depicted in Figures 1A through 4, the upper fillet extends beyond the upper ring 94a, and the upper end of the upper fillet is located near the upper edge of the hollow cylindrical body of the nozzle 94. The upper end of the lower thread of the outer thread 95 is connected to the lower portion of the upper ring 94a as shown in Figures 1A through 4. The lower ends of the upper and lower threads of each outer thread segment 95 extend to the lower portion of the nozzle body 94.

 The lid 89 comprises a hollow cylindrical body whose upper edge is affixed to a lid member 89a. The inner region of the hollow cylindrical body of the cap 89 is provided with at least one inner thread segment 91, in the Figures being three inner thread segments 91, by way of example only, not limiting. Each inner thread segment 91 is designed to engage the respective outer thread segment 95 of nozzle 94. Of course, the number of inner thread segments 91 employed in cap 89 should be the same number of outer thread segments 95 as nozzle 94. .

 As previously mentioned, in Figures 1 to 4 the lid 89 is depicted in section.

However, to facilitate understanding of the invention, the internal thread segments 91 of the front portion of the cap 89, which should not appear in views where the cap 89 is pictured in section, have been retained in the Figures.

 The lid 89 is also provided with a cutting device 92 which comprises a hollow cylindrical body whose upper edge is affixed to the lower region of the lid 89a of the lid 89. The lower region of the cutting device 92 is provided with steel. least one cutting element 92a.

The locking device 96 comprises a hollow body provided with a cylinder-shaped lower region, the upper edge of which is affixed to a frusto-conical upper region. The upper edge of this upper trunk region has a diameter smaller than the lower edge diameter. The edge of the inner lower region of the locking device 96 is provided with a plurality of lower locking elements 93, each of which in the present embodiment comprises a body projecting obliquely upwardly towards the imaginary axis of the locking device. 96. The lower locking elements 93 are designed to be able to perform small radial flexions as opposed to the geometric axis of the locking device 96. The upper edge of the frusto-conical upper region of the locking device 96 is provided with a plurality of breaking elements 96a which are also connected to the lower edge of the cover.

89, forming a rupturable interconnection between the locking device 96 and the lid 89. The function of the breaking elements 96a will be realized by the description that will be given below with respect to the mode of operation of the automatic container opening device 90.

 In Figure 1A, the assembly formed by the lid 89 and the locking device 96 can be observed in a position immediately prior to the beginning of its insertion in the nozzle 94, to begin the assembly operation of the automatic container opening device 90. , factory-made operation using a tool specially dedicated for this purpose. The cap 89 should be inserted into the nozzle 94 in the direction indicated by the arrow W shown in Figure 1A.

 [024] Figure 2 depicts the cap 89 fully inserted into the nozzle 94. It is important to note that the situation depicted in this Figure indicates that the lower locking elements 93 of the locking device 96 have already passed the locking ring 97. whereas the lower locking elements 93 touched the upper edge of the locking ring 97 they flexed in opposition to the geometric axis of the locking device 96, which allowed the lower locking elements 93 to pass through the locking ring 97.

 Consequently, the lid 89 was locked in that position depicted in Figure 2, and can no longer be removed by upward longitudinal movements. This is the mounting position where lid 89 and nozzle 94 must remain to form the automatic container opening device.

90, so that the latter can be applied to a container, factory-made operation by means of a tool specially dedicated for that purpose. After being properly assembled, automatic container opening device 90 should be applied, for example, to aseptic carton packs or plastic pouch packs.

 [026] In order to be able to remove lid 89 from the automatic container opening device 90 it will first be necessary to apply a counterclockwise rotation movement as indicated by the curved arrow T in Figure 3. When this counterclockwise rotation movement time is applied, initially each inner thread segment 91 of cap 89 will screw into its respective outer thread segment 95 of nozzle 94. Then, with continued counterclockwise rotation, the rupturing elements 96a will break, which will allow the counterclockwise rotation of the cap 89 to continue.

Note that extending beyond the upper ring 94a of the upper portion of each upper thread of the outer thread segments 95 will ensure that each inner thread segment 91 can be screwed into its respective outer thread segment 95, therefore, when each inner thread segment 91 touches the extended upper fillet of its outer thread segment 95, the only possibility for the counterclockwise rotation to continue is to thread each inner thread segment 91 into its thread segment. external 95. [028] The cutting device 92, being rigidly attached to the lid 89, will evidently perform the same movements as the lid 89. Thus, with the continued counterclockwise rotation of the lid 89, the cutting device 92 will perform the same counterclockwise rotation movement as cap 89. Concurrent with this counterclockwise rotation movement, cap 89 will also perform a downward axial movement resulting from screwing in the internal thread segments 91 of cap 89 in their respective outer thread segments 95 of the nozzle 94, as indicated by the arrow W in Figure 3. Consequently, the cutting device 92 will perform the same downward axial movement indicated by the arrow W in Figure 3.

 The composition of the counterclockwise and downward rotation motions effected by the cutting device 92 will cause the cutting elements 92a of the cutting device 92 to cut the sealing member of the container located below the nozzle 94 of the device. for automatic container opening 90, which may be the aluminum layer of an aseptic carton, or a sealing member applied around the flange hole 99, or the plastic layer of a plastic pouch package. In Figure 3 the cutter is pictured in its final position after the cap 89 has reached the lowest position in the screwing operation described above when the lower region of the cap 89 touches the upper edge of the nozzle 94. .

 Once the package has been properly opened as described above, it is sufficient to unscrew the lid 89 from the nozzle 94 so that the passage of the product contained within the package can take place through the nozzle 94 to be served. Simply rotate the cap 89 clockwise as indicated in Figure 4 by the curved arrow T, and consequently the cap 89 will proceed with a concomitant upward axial movement, indicated in Figure 4 by the arrow W, until it is fully rotated. unscrewed nozzle 94.

 It is important to note that in Figures 1A through 4 the inner thread segments 91 of the cap 89 and the outer thread segments 95 of the nozzle 94 comprise a left orientation thread. The choice of this type of orientation is because it is customary for people to use right-hand threaded cap and nozzle assemblies where the cap is unscrewed by counterclockwise rotary movements that cause upward axial movements of the same.

 As in the present embodiment of the invention it is necessary that the cap 89, in the first actuation, make a downward axial movement for the sealing element to be ruptured, so it was preferred to use a left-oriented thread, since the Usual use of right-hand threaded threads would certainly lead most users to turn the cap counterclockwise. After this first cap unscrewing operation 89 users would then understand how to perform the unscrewing or unscrewing operations of cap 89 on the nozzle 94 by applying the proper rotating movements for these operations.

It is important to note that there is no impediment for the inner thread segments 91 of the cap 89 and the outer thread segments 95 of the nozzle 94 to comprise an orientation thread to the right. In this case, users would have to be instructed to initially perform an initial rotational movement of the cap 89 clockwise, to cause downward axial movement thereof and to cause the sealing member to rupture.

 Figures 5 to 11 depict a further embodiment of the automatic container opening device according to the present invention. As can be seen from the Figures, an automatic container opening device 100 is shown which comprises an upper sealing member 101a and a base member 101b, a nozzle 107 and a locking device 104. In Figures 5 to 11 the upper sealing member 101a, base member 101b and locking device 104 are cut-away depicted.

 The nozzle 107 comprises a hollow cylindrical body whose upper region is provided with an upper ring 107a located near the upper edge of the hollow body of the nozzle 107, with a spacing between the upper region of the upper ring 107a and the upper edge. of the nozzle 107. The median region of the nozzle body 107 is provided with a secondary locking ring 107b.

 The lower edge of the nozzle 107 is affixed to the upper region of a primary locking ring 109, the lower region of which is affixed to the upper region of a base member 110, which comprises a hollow cylindrical body whose inner diameter must be larger. or at least identical to the inside diameter of the nozzle 107. The lower region of the base member 110 is affixed to the upper region of a flange 111 which is provided with a hole of greater diameter or at least identical to the inside diameter of the base element 110. , to which it is connected. The imaginary geometric axes of the base element 110 and the hole of the base element 111 are coincident.

 The outer region of the nozzle 107 is provided with at least one outer thread segment 108, with three non-limiting outer thread segments 108 being shown by way of example only. Each outer thread segment 108 comprises two upper and lower threads. As depicted in Figures 5 to 11, the upper portion 108a of the upper fillet extends beyond the upper ring 107a, and the upper end of the upper portion 108a of the upper fillet is located near the upper edge of the hollow cylindrical nozzle body 107. The upper end of the lower thread of the outer thread 108 is connected to the lower portion of the upper ring 107a as depicted in Figures 5 to 11. The lower ends 108b of the upper and lower threads of each outer thread segment 108 extend to the lower portion of the body of the mouthpiece 107.

 The upper sealing member 101a comprises a substantially circular, disc-shaped flat body whose lower region is provided with a sealing projection 101a 'which has the shape of a cylinder trunk, the upper edge of the sealing projection 101a. being rigidly affixed to the lower region of the upper sealing member 101a, as can be seen from the Figures.

The base member 101b comprises a hollow cylindrical body whose inner region is provided with at least one inner thread segment 102, in the Figures being three inner thread segments 102, by way of example only, not limiting. Each internal thread segment 102 is designed to screwing into the respective outer thread segment 108 of the nozzle 107. Of course, the number of inner thread segments 102 employed in the base member 101b should be the same number of outer thread segments 108 of the nozzle 107.

 [040] In the embodiment depicted in Figures 5 to 11, the upper sealing member 101a, when in the closed position, depicted in Figure 6, rests on the base member 101b, and both are connected by means of a swiveling connecting member 112. , as shown in more detail in Figure 5. There are variations of this type of tilt connection, which may be used interchangeably with the present invention. In addition, any other type of connecting means may be used to connect the upper sealing member 101a to the base member 101b. It is even possible that there is no means of connection between them, in which case the connection between these two parts could be made by pressure or screwing, for example.

 As previously mentioned, in Figures 5 to 11 the base element 101b is pictured in section. However, to facilitate understanding of the invention, the internal thread segments 102 of the front portion of the base member 101b, which should not appear in views where the base member 101b is pictured in section, have been retained in the Figures.

 The base member 101b is also provided with a cutting device 106 which comprises a hollow cylindrical body whose upper edge is affixed to the inner upper region of the base member 101b by means of a connecting ring 113. bottom of the cutting device 106 is provided with at least one cutting element 106a.

 The edge of the lower inner region of the base member 101b is provided with a plurality of upper locking elements 103, each of which in the present embodiment comprises a body projecting obliquely upward toward the imaginary axis. of the base element 101b. The upper locking elements 103 are designed to be able to effect small radial flexions as opposed to the geometric axis of the base element 101b.

 Locking device 104 comprises a hollow body provided with a cylinder-shaped lower region, the upper edge of which is affixed to a frusto-conical upper region. The upper edge of this upper trunk region has a diameter smaller than the lower edge diameter. The edge of the inner lower region of the locking device 104 is provided with a plurality of lower locking elements 105, each of which in the present embodiment comprises a body that projects obliquely upwardly toward the imaginary axis of the locking device. 104. The lower locking elements 105 are designed to be able to effect small radial flexions as opposed to the geometry of the locking device 104.

The upper edge of the frusto-conical upper region of the locking device 104 is provided with a plurality of rupture elements 104a which are also connected to the lower edge of the base element 101b, forming a rupturable interconnection between the locking device. lock 104 and the base member 101b. The function of the rupture elements 104a will be perceived by the description that will be below with respect to the mode of operation of the automatic container opening device

100

 [046] In Figure 5 it can be seen the assembly formed by the upper sealing member 101a, the base member 101b and the locking device 104 in a position immediately prior to the beginning of their insertion in the nozzle 107, to begin the operation of automatic container opening device assembly 100, factory-made operation by means of a tool specially dedicated for this purpose. The assembly formed by the upper sealing member 101a, the base member 101b and the locking device 104 must be inserted into the nozzle 107 in the direction indicated by the arrow W shown in Figure 5.

 Figure 6 depicts the assembly formed by the upper sealing member 101a, the base member 101b and the locking device 104 partially inserted into the nozzle 107. Figure 7 depicts the assembly formed by the upper sealing member 101a, the member 101b and locking device 104 already fully inserted into the nozzle 107. It is important to note that the situation depicted in that Figure indicates that the lower locking elements 105 of the locking device 104 have already passed the primary locking ring 109. whereas the lower locking elements 105 touched the upper edge of the primary locking ring 109 they flexed in opposition to the geometric axis of the locking device 104, which allowed the lower locking elements 105 to pass through the primary locking ring 109.

 Accordingly, the assembly formed by the upper sealing member 101a, the base member 101b and the locking device 104 has been locked in that position depicted in Figure 7 and can no longer be removed by upward longitudinal movements. This is the mounting position in which the assembly formed by the upper sealing member 101a, the base member 101b and the locking device 104 and the nozzle 107 must remain to form the automatic container opening device 100 so that the latter can be applied to a container, factory operation by means of a tool specially dedicated for that purpose. Once properly assembled, the automatic container opening device 100 should be applied, for example, to aseptic carton packs or plastic pouch packs.

When it is necessary to open the container, whether aseptic carton or plastic pouch, counterclockwise movement shall be applied to the assembly formed by the upper sealing member 101a and the base member 101b. When this counterclockwise rotation motion is applied, initially each inner thread segment 102 of the base member 101b will engage its respective outer thread segment 108 of the nozzle 107. Then, with the continuity of the rotational motion counterclockwise, the rupture elements 104a will be ruptured, which will allow continuity of counterclockwise rotation of the assembly formed by the upper sealing element 101a and the base element 101b. Note that the upper portion 108a of each upper thread of the outer thread segments 108 extending beyond the upper ring 107a of the nozzle 107 will ensure that each inner thread segment 102 of the base member can be threaded. 101b in its respective outer thread segment 108, because when each inner thread segment 102 touches the upper portion 108a of the respective upper thread, the only possibility for the counterclockwise rotation to continue is to screw each thread internal thread 102 into the respective outer thread segment 108.

The cutting device 106, being rigidly attached to the base member 101b, will of course perform the same movements as the base member 101b. Thus, with the continuity of counterclockwise rotation of the assembly formed by upper sealing member 101a and base member 101b, the cutting device 106 will perform the same counterclockwise rotation movement as that of the assembly formed. by the upper sealing member 101a and the base member 101b.

 Concomitantly with this movement, the assembly formed by the upper sealing member 101a and the base member 101b will also effect a downward axial movement resulting from threading the internal thread segments 102 of the base member 101b into their respective thread segments. 108 of the nozzle 107 as indicated by the arrow W in Figure 7. Accordingly, the cutting device 106 will perform the same downward axial movement indicated by the arrow W in Figure 7.

 [053] The composition of the counterclockwise and downward rotation motions effected by the cutting device 106 will cause the cutting elements 106a of the cutting device 106 to cut the sealing member of the container located below the automatic opening device. of container 100, which may be the aluminum layer of an aseptic carton pack, or a sealing member applied around the flange hole 111, or the plastic layer of a plastic pouch pack.

[054] In Figure 8 the cutting device is pictured in the final position where it will be after the assembly formed by the upper sealing member 101a and the base member 101b has reached the lowest position in the screwing operation described above when the upper edge of the nozzle 107 touches the lower region of the connecting ring 113, as can be seen in more detail in Figures 10 and 11.

Note in Figure 8 that the upper locking elements 103 have passed the secondary locking ring 107b of the nozzle 107. At the time the upper locking elements 103 have touched the upper edge of the secondary locking ring 107b they have flexed in opposition to the geometric axis of the base member 101b, which allowed the upper locking elements 103 to pass through the secondary locking ring 107b. In Figure 9 a Detail X of Figure 8 is shown which depicts at a greater extent the upper locking elements 103 having already passed the secondary locking ring 107b. Consequently, the assembly formed by the upper sealing member 101a and the base member 101b has been locked in that position depicted in Figure 8, and can no longer be removed by upward longitudinal movements. The use of the upper locking elements 103 is optional, and is intended only to prevent removal of the assembly formed by the upper sealing member 101a, the base member 101b. Optionally, the locking may be done between the inner thread segments 102 and the outer thread segments 108 at the end of their threading.

 Once the package has been properly opened, as described above, it will be sufficient to pivot the upper sealing member 101a so that the passage of the product contained within the package can take place through the nozzle 107 to be served. Figures 10 and 11 depict the automatic container opening device 100 with the upper sealing member 101a depicted in the closed and open positions, respectively.

 As can be seen from Figures 10 and 11, the upper sealing member 101a is pictured with a front flap for the purpose of facilitating the tilting operation when it is necessary to open the passage of the product contained within the housing. packaging through the nozzle 107. Use of this front flap is optional, and other means may be used to facilitate tilting the upper sealing member 101a.

 It is important to note that in Figures 5 to 11 the inner thread segments 102 base member 101b and the outer thread segments 108 of the nozzle 107 comprise a left orientation thread. Similarly to what has been commented with respect to the embodiment of the above-described automatic container opening device 90, with reference to drawings IA to 4, the choice of such orientation is due to the fact that it is customary for people to use cap and nozzle assemblies. with right-hand orientation threads, in which the cap is unscrewed by counterclockwise rotary movements that cause upward axial movements of the cap.

 As in the present embodiment of the invention it is necessary that the assembly formed by the upper sealing member 101a and the base member 101b make a downward axial movement in the first drive for the sealing member to be ruptured, so it was preferably chosen to be A left-hand thread is used, as the usual use of right-hand threads could cause most users to turn the cap counterclockwise.

 After this first actuation of the assembly formed by the upper sealing member 101a and the base member 101b there will no longer be any need to apply any rotational motion to any of the components of the automatic container opening device 100. As seen from the description. of the present embodiment of the invention, to serve the product contained in the container, it will be sufficient to pivot the upper sealing member 101a to open the passageway through the nozzle 107.

It is important to note that there is no impediment for the inner thread segments 102 of the base member 101b and the outer thread segments 108 of the nozzle 107 to comprise a right-hand orientation thread. In this case, users would have to be instructed to initially rotate the assembly formed by the upper sealing member 101a and the base member 101b clockwise to cause downward axial movement thereof and cause the sealing member to rupture. . Figures 12 to 19 depict a further embodiment of the automatic container opening device according to the present invention. As can be seen from the Figures, an automatic container opening device 120 is shown which comprises an upper sealing member 121a and a base member 121b, a nozzle 127 and a locking device 124. In Figures 12 to 19 the upper sealing member 121a, base member 121b and locking device 124 are pictured in section.

 The nozzle 127 comprises a hollow cylindrical body whose upper region is provided with an upper ring 127a located near the upper edge 129 of the hollow body of the nozzle 127, with a spacing between the upper region of the upper ring 127a and the edge. 129 of the nozzle 127. The lower edge of the nozzle 127 is affixed to the upper region of a flange 130, which is provided in its outer region with at least one socket recess 131, in the Figures four socket recesses 131 are shown only for example, not limiting. Flange 130 is provided with a hole whose diameter is substantially identical to the inside diameter of nozzle 127 to which it is connected. The imaginary geometric axes of flange 130 and nozzle 127 are coincident.

 The outer region of the nozzle 127 is provided with at least one outer thread segment 128, in the Figures being three outer thread segments 128, by way of example only, not limiting. Each outer thread segment 128 comprises two upper and lower threads. As depicted in Figures 12 to 19, the upper portion 128a of the upper fillet extends beyond the upper ring 127a, and the upper end of the upper portion 128a of the upper fillet is located near the upper edge of the hollow cylindrical body of the nozzle 127.

 [065] The upper end of the lower thread of the outer thread 128 is connected to the lower portion of the upper ring 127a as depicted in Figures 12 to 19. The lower ends 128b of the upper and lower threads of each outer thread segment 128 extend to the lower portion of the nozzle body 127.

The upper sealing member 121a comprises a substantially circular, disc-shaped flat body whose lower region is provided with a sealing projection 121a 'which has the shape of a cylinder trunk, the upper edge of the sealing projection 121a. being rigidly affixed to the lower region of the upper sealing member 121a, as can be seen in the Figures.

 Base member 121b comprises a hollow cylindrical body whose inner region is provided with at least one inner thread segment 122, in Figures 12 to 19, three inner thread segments 122 being shown, by way of example only, not by way of example. . Each inner thread segment 122 is designed to engage the respective outer thread segment 128 of the nozzle 127. Of course, the number of inner thread segments 122 employed in the base element 121b should be the same number of outer thread segments 128 as the mouthpiece 127.

As previously mentioned, in Figures 12 to 19 the base element 121b is pictured in section. However, to facilitate the understanding of the invention, the segments of inner thread 122 of the front portion of the base member 121b, which should not appear in views where the base member 121b is pictured in section.

 The edge of the lower inner region of the base member 121b is provided with a plurality of upper locking elements 123, each of which in the present embodiment comprises a body projecting obliquely upward toward the imaginary axis. of base element 121b. The upper locking elements 123 are designed to be able to perform small radial flexions as opposed to the geometric axis of the base element 121b.

 The base member 121b is also provided with a cutting device 126 which comprises a hollow cylindrical body whose upper edge is affixed to the upper region of the base member 121b by means of a connecting ring 133. The lower region of the cutting device 126 is provided with at least one cutting element 126a.

 [071] In the embodiment depicted in Figures 12 to 19 the upper sealing member 121a, when in the closed position, depicted in Figure 13, rests on the base member 121b, and both are connected to each other by means of a tiltable member. connection 132, as shown in more detail in Figure 12. There are variations of this type of tilt connection, which may be used interchangeably with the present invention. In addition, any other type of connecting means may be used to connect the upper sealing member 121a to the base member 121b. It is even possible that there is no means of connection between them, in which case the connection between these two parts could be made by pressure or screwing, for example.

 The locking device 124 comprises a substantially cylindrical hollow body, the upper edge of which is provided with a plurality of rupture elements 124a, which are also connected to the lower edge of the base element 121b, forming a rupturable interconnection between. locking device 124 and base member 121b. The function of the rupture elements 124a will be apparent from the description to be given below with respect to the mode of operation of the automatic container opening device 120.

 The outer lower region of the locking device 124 is provided with a plurality of locking elements 125, which comprise radial projections extending away from the body of the locking device 124. In Figures 12 to 19, four elements are depicted. No. 125, for illustration only, not limiting. As will be seen later, the locking elements 125 are designed to fit into the locking recesses 131 of the flange 130, as will be seen later.

[074] Figure 13 shows the assembly formed by the upper sealing member 121a, the base member 121b and the locking device 124 in a position immediately prior to the beginning of their insertion into the nozzle 127, to initiate the operation. assembly of the automatic container opening device 120, factory-made operation by means of a tool specially dedicated for this purpose. The assembly formed by the upper sealing member 121a, the base member 121b and the locking device 124 must be inserted into the nozzle 127 in the direction indicated by the arrow W shown in Figure 13.

 Figures 14 and 15 depict the assembly formed by the upper sealing member 121a, the base member 121b and the locking device 124 already fully inserted into the nozzle 127, forming the automatic container opening device 120. It is important to note that the situation depicted in Figure 14 indicates that the locking members 125 of the locking device 124 have already been engaged in the locking recesses 131 of the flange 130. Refer to Figures 13 and 14 the locking elements 125 of the locking device 124 before (Figure 13) and then (Figure 14) that the assembly formed by the upper sealing member 121a, the base member 121b and the locking device 124 have been fully inserted into the nozzle 127. In Figure 15 it can be seen that the engagement of the sealing members locking 125 into the locking recesses 131 occurred such that the lower regions of the locking elements 125 remained substantially flush with the bottom of flange 130.

 Preferably the engagement of the locking members 125 of the locking device 124 into the locking recesses 131 of the flange 130 should be by interference, which means that at least some outer region of the locking elements 125 must have slightly larger dimensions. that the internal dimensions of the locking recesses 131 in the regions where the locking will take place. Accordingly, after the locking members 125 are properly seated in the locking recesses 131, the joint between the nozzle 127 and assembly formed by the upper sealing member 121a, the base member 121b and the locking device 124, to form the device. for automatic container opening 120, it will be strong enough to prevent the components from separating again.

 The situation depicted in Figures 14 and 15 is the mounting position in which the assembly formed by upper sealing member 121a, base member 121b and locking device 124 and nozzle 127 must remain to form the device for automatic container opening 120 so that the latter can be applied to a container, factory-made operation by means of a tool specially dedicated for this purpose. After being properly assembled, automatic container opening device 120 should be applied, for example, to aseptic carton packs or plastic pouch packs.

[078] When opening the container, whether aseptic carton or plastic bag packaging, counterclockwise rotation shall be applied to the assembly formed by the upper sealing member 121a and the base member 121b, as indicated in Figure 16 by the curved arrow T. When this counterclockwise rotation motion is applied, each inner thread segment 122 of the base member 121b will initially engage its respective outer thread segment 128 of the nozzle 127. Then, as the counterclockwise rotation continues, the rupture elements 124a will be ruptured, which will allow the counterclockwise rotation of the assembly formed by the upper sealing member 121a and the element to break. base 121b. [079] The upper portion 128a of each upper thread of the outer thread segments 128 extending beyond the upper ring 127a of the nozzle 127 will ensure that each inner thread segment 122 of the base member 121b can be screwed into place. respective outer thread segment 128, as shown in Figure 14. When each inner thread segment 122 touches the upper portion 128a of its upper thread, the only possibility for the counterclockwise rotation to continue is to threading each inner thread segment 122 into the respective outer thread segment 108.

 The cutting device 126, being rigidly attached to the base member 121b, will evidently perform the same movements as the base member 121b. Accordingly, with the continuity of the counterclockwise rotation of the assembly formed by the upper sealing member 121a and the base member 121b, the cutting device 126 will perform the same counterclockwise rotation movement as the assembly formed. by the upper sealing member 121a and the base member 121b.

 Concomitantly with this counterclockwise rotation movement, the assembly formed by the upper sealing member 121a and the base member 121b will also effect a downward axial movement as a result of screwing the internal thread segments 122 of the base member. 121b in their respective outer thread segments 128 of the nozzle 127, as indicated by the arrow W in Figure 16. Consequently, the cutting device 126 will perform the same downward axial movement indicated by the arrow W in Figure 16.

 [082] The composition of the counterclockwise and downward rotation motions effected by the cutting device 126 will cause the cutting elements 126a of the cutting device 126 to cut the sealing member of the container located below the automatic opening device. of container 120, which may be the aluminum layer of an aseptic carton, or a sealing member applied around the flange hole 130, or the plastic layer of a plastic pouch package.

[083] In Figure 16 the cutting device is pictured in the final position where it will be after the assembly formed by the upper sealing member 121a and the base member 121b has reached the lowest position in the screwing operation described above when the upper edge 129 of the nozzle 127 touches the lower region of the connecting ring 133, as can be seen in more detail in Figure 16.

Note in Figure 16 that the upper locking elements 123 have passed the secondary locking ring 127b of the nozzle 127. At the time the upper locking elements 123 have touched the upper edge of the secondary locking ring 127b they have flexed in opposition to the geometric axis of the base member 121b, which allowed the upper locking elements 123 to pass through the secondary locking ring 127b. In Figure 17 a Detail Z of Figure 16 is shown, which enlargedly depicts the upper locking elements 123 having already passed the secondary locking ring 127b. Consequently, the set formed by the upper element of 121a and base member 121b were locked in this position shown in Figure 16 and can no longer be removed.

 [085] Once the package has been properly opened as described above, the upper sealing member 121a will simply have to be swung so that the product contained within the package can pass through the nozzle 127 to be served. Figures 18 and 19 depict the automatic container opening device 120 with the upper sealing member 121a depicted in the closed and open sectional positions, respectively.

 [086] The upper sealing member 121a shown in Figures 18 and 19 may be provided with a front flap for the purpose of facilitating the tilting operation when it is necessary to open the passage of the product contained within the package through the housing. nozzle 127. The use of this front flap is optional, and other means may be used to facilitate tilting the upper sealing member 121a.

It is important to note that in Figures 12 to 19 the inner thread segments 122 base member 121b and the outer thread segments 128 of the nozzle 127 comprise a left orientation thread. Similar to the above regarding the embodiment of the automatic container opening device 90 and 100, previously described with reference to drawings IA 4 and 5 to 11, respectively, the choice of this type of orientation is due to the fact that it is customary for People use right-hand threaded cap and nozzle assemblies where the cap is unscrewed by counterclockwise rotary movements that cause upward axial motions of the cap.

As in the present embodiment of the invention it is necessary that the assembly formed by the upper sealing member 121a and the base member 121b make a downward axial movement in the first drive for the sealing member to be ruptured, so it was preferably chosen to be A left-hand thread is used, as the usual use of right-hand threads could cause most users to turn the cap counterclockwise.

 After this first actuation of the assembly formed by the upper sealing member 121a and the base member 121b there will no longer be any need to apply any rotational motion to any of the components of the automatic container opening device 120. As seen from the description. of the present embodiment of the invention, to serve the product contained in the container, it is sufficient to pivot the upper sealing member 121a to open the passage through the nozzle 127.

 [090] It is important to note that there is no impediment for the inner thread segments 122 of the base member 121b and the outer thread segments 128 of the nozzle 127 to comprise a right orientation thread. In this case, users would have to be instructed to initially rotate the assembly formed by the upper sealing member 121a and the base member 121b clockwise to cause downward axial movement thereof and cause the sealing member to rupture. .

[091] Figure 20 depicts an example of using an automatic container opening device in an aseptic carton pack. Any of the three embodiments of the invention previously described may be applied to the aseptic carton pack depicted in Figure 20. Figures 21 and 22 depict examples of using an automatic container opening device in a plastic pouch package. Any of the three embodiments of the invention described above may be applied to the plastic pouch packages depicted in Figures 21 and 22.

 [092] The invention has been described in connection with some of its embodiments applicable to aseptic carton packs and nozzle packs and plastic bag packs, in which the sealing member of a container is cut by means of a rotary rotating device. although not limited to such embodiments only. However, it is also possible to use the drive mechanisms disclosed in the embodiments of the present invention to drive cutting devices in which the cutting operation of the sealing member is not performed by rotary cutting.

 [093] For example, a drive mechanism may be employed in accordance with any of the embodiments of the present invention in conjunction with the nozzle disclosed in document W003035491, the contents of which are included in this report for reference to achieve the same effect as that obtained. using the drive mechanism originally disclosed in document W003035491.

 In that case, instead of employing a cutting device such as those disclosed in the embodiments of the present invention, which cuts the sealing member by rotation, at least one meat, similar to the meat 8 of the invention of the invention, would be employed. W003035491, which would be affixed to the cap or base elements of the embodiments disclosed in this report. It would also be necessary to include in the nozzles for the embodiments disclosed in this report a tilting cutting element, similar to the tilting cutting element 26 of the invention of PI9213426-8, which would be provided with a meat follower similar to the meat follower 32 of the present invention. invention of document PI9213426-8.

 An automatic container opening device operating in a similar manner to the embodiments of the present invention, provided with the modifications mentioned in the previous paragraph, would, without difficulty, provide for the opening of an aseptic carton pack or a plastic pouch pack.

 In this case, the initial drive would be exactly as described for the embodiments disclosed in this report by applying rotary motion to the lid or assembly formed by the upper sealing member and the base member. The rupture of the rupture elements connecting the locking device to the cover or assembly formed by the upper sealing member and the base member would then initially occur.

[097] Next, there would be threading of the internal thread elements of the lid or assembly formed by the upper sealing member and the base member, and following such screwing the interaction between the meat and the meat follower would cause the tilting cutting member cut the sealing member of the aseptic carton or plastic pouch package to open the package and allow the product contained therein to be served through the nozzle. For demonstration purposes only, Figures 23 to 26 depict an automatic container opening device 120 'which is a variation of the third embodiment of the invention. The automatic container opening device 120 'incorporates the same meat-based and meat follower drive principle mentioned in the preceding paragraphs, well known in the art, rather than using a screwing system. It is important to mention that the same could be done in either of the two other embodiments disclosed in this application.

 Differences between the automatic container opening devices 120 and 120 'can be seen in the comparison of Figures 12 to 19 with Figures 23 to 26. The mouthpiece 127' of the automatic container opening device 120 'is provided with a tilting cutting member 134 which is attached to the lower region of the nozzle 127 'by means of a flexible member not pictured in Figures 12 to 19 as is well known in the art. The lower region of the cutting tipper 134 is provided with a plurality of cutting elements 137, and the upper region of the cutting tipper 134 is provided with a cam 135.

 [100] The base member 121b 'of the automatic container opening device 120' comprises hollow cylindrical body provided with a cam follower 136 which is affixed to the inner region of the base member 121b '. The other components of the automatic container opening device 120 'are the same or similar to the equivalent components of the automatic container opening device 120', and therefore the indicative numerals used in Figures 23 to 26 are the same. Accordingly, the assembly of the components of the automatic container opening device 120 'will be carried out in the same manner as described with respect to the automatic container opening device 120, and for this reason the description of such operation will not be repeated here.

 [101] In Figure 23 the automatic container opening device 120 'is pictured in a position immediately prior to the beginning of its insertion into the nozzle 127', to begin the assembly operation of the automatic container opening device 120 ', operation factory made using a tool specially dedicated for this purpose. The assembly formed by the upper sealing member 121a, the base member 121b 'and the locking device 124 shall be inserted into the nozzle 127 in the direction indicated by the arrow W shown in Figure 23.

 [102] In Figure 24 the automatic container opening device 120 'is pictured in the final mounting position, ready to be applied to a package, either aseptic carton pack or plastic pouch pack. It can be seen that the engagement of the locking members 125 into the locking recesses 131 has occurred such that the lower regions of the locking elements 125 remain substantially flush with the lower region of the flange 130.

[103] When it is necessary to open the container, a counterclockwise rotation movement must be applied to the assembly formed by the upper sealing member 121a and the base member 121b '. When this counterclockwise rotation motion is applied, the meat follower 136 will touch the meat 135, and as the counterclockwise rotation motion continues the element cutting tipper 134 will swing toward the container sealing member, which may be the aluminum layer of an aseptic carton, a sealing member applied to the lower flange region 130 or the plastics material of a plastic pouch package.

 [104] At the end of the counterclockwise rotation the cutting elements 137 of the tilting cutting member 134 will have cut the material below the nozzle 127 ', either the aluminum layer of an aseptic carton, a sealing element applied to the lower region of the flange 130 or the plastic material of a plastic bag package, and the container will be open. The contents of the package may be served by passing through the nozzle 127 '. Figures 25 and 26 depict the automatic container opening device 120 'after this cutting operation has been completed. In Figure 25 the upper sealing member 121a is in the closed position, and in Figure 26 in the open position.

 [105] Modifications or substitutions may be made to the embodiments of the invention described in this report without, however, altering the inventive concept disclosed herein. Accordingly, the invention is not limited solely to the embodiments described in this report, but is limited only to the claims accompanying this report.
