DEVICE FOR AUTOMATIC OPENING OF CONTAINER PROVIDED WITH SEALING ELEMENT

FIELD OF THE INVENTION [0001] The present invention relates to a device for automatic opening of the container that has a mouthpiece provided with a sealing element firmly attached to its edge, said device for automatic opening of the container being provided with means that eliminate the need to perform multiple operations to remove the sealing element from the edge of the nozzle that are usually necessary to perform the removal of the sealing element and release the administration of the product stored therein. The device for automatic opening of the container according to the invention makes it unnecessary to remove the lid of the container to release the administration of the product stored therein.

RELATED TECHNIQUE [0002] The use of sealing elements in containers for storing products such as condiments for food, soups, liquid or pasty products, medicines, cosmetics and other products is well known. Normally the sealing element is firmly attached to the opening through which the product can be removed from the container, for example at the mouth of a pouring nozzle.

[0003] Usually a closing element is provided in the spouting nozzle, usually a cap, which is often provided with an internal thread to engage an external thread provided in the spouting nozzle. The lid will only be used to seal the container after a consumer removes the sealing element from the mouthpiece of the nozzle.

[0004] Several types of sealing elements are known for the mouth of the pouring nozzles of these containers, whose characteristics vary according to the type of product contained in the container. Usually the sealing elements comprise a multilayer material, which can be made of plastic materials, paper, aluminum films, etc. US6277478, US6461714, US7648764 and US8080118 disclose some types of sealing elements.

[0005] There are several reasons for promoting the sealing of the container by means of sealing elements applied to the mouth of the pouring nozzle, and among them can be mentioned the need to provide barriers against light, odors, aromas, moisture, oxygen, etc. , factors that can compromise the quality and integrity of the product stored in the container.

Petition 870180128395, of 10/09/2018, p. 33/86

For this reason, sealing elements can usually be manufactured in layers of different materials, each of them meeting specific needs.

[0006] The sealing elements can also be a means to extend the shelf life of the products stored in the containers, as there are cases in which the sale to the final consumer occurs long after the date of manufacture. In some cases, the sale may take place in periods longer than one year after manufacture.

[0007] The sealing elements also serve as an indication to the consumer that the contents of the container have not been violated. If the sealing element shows any sign of violation when the lid is opened, this will signal to the consumer that the container has been violated and the product may have suffered some type of contamination and, therefore, should not be used.

[0008] For this reason, container lids with nozzles with sealing elements in the mouth are often not provided with anti-vandalism devices, since the sealing element itself serves this purpose. This makes it possible for consumers, when choosing the product to buy, to open the covers of the products to verify that the sealing element is intact.

[0009] In these situations, it may occur that consumers may inadvertently damage the sealing element, which would take the product contained in the container unsuitable for sale. To avoid this possibility, it is common for sealing elements to be manufactured with layers of thicker materials than would be necessary to serve as a barrier element, which increases manufacturing costs. The provision of more resistant sealing elements additionally increases its strength, which can prevent the sealing element from being torn when the removal operation is performed.

[0010] Whatever the reason for providing thicker sealing elements, this option usually creates difficulties for consumers, as it makes it very difficult to remove the sealing element when it is necessary to open the container for the first time, to use the product contained therein.

[0011] If the product is a condiment or a cream, for example, it is common for the cap to be provided with a pouring orifice that makes it possible to administer the product without the need to disengage the cap from the mouthpiece. In such cases, after removing the sealing element, the lid must be re-engaged to the nozzle, to close the container and allow the product to be served normally through the pouring hole.

[0012] When it is necessary to remove part or all of the product stored in the container for the first time, it will then be necessary to unscrew the nozzle cover and carry out the

Petition 870180128395, of 10/09/2018, p. 34/86

3/50 removal of the sealing element attached to the mouth of the mouthpiece. Then, the cap should normally be screwed back onto the nozzle to keep the container closed, if all the product stored in the container has not been used.

[0013] In some cases the sealing elements are provided with at least one side flap, which extends beyond the mouth of the mouthpiece, which aims to facilitate the task of removing the sealing element. These flaps are normally flush with the outer portion of the mouthpiece, near the mouth of the mouthpiece, and the consumer should lift one of them, pick it up with the fingertips, usually the thumb and forefinger, and make an upward movement, aiming remove the sealing element. Even so, even with the provision of these side flaps, the task of removing the sealing element is difficult, and with a certain frequency the operation of removing the sealing element is not carried out, because it is so firmly adhered to the mouth of the mouthpiece that the consumer is unable to withdraw.

[0014] There are occasions when there is a tearing of the sealing element at the time of the operation for its removal, and only part of it is removed. This forces the consumer to look for ways to remove the rest of the sealing element that was still attached to the mouthpiece of the mouthpiece. This operation is not always easy to perform, as it will be very difficult for the consumer to even manage to handle the remaining parts that were adhered to the mouthpiece of the mouthpiece, in order to remove them. Often the consumer makes use of a sharp instrument, such as the tip of a knife or scissors, to assist in removing the remainder of the sealing element, which can generate an accident, in addition to creating the possibility of contamination of the product.

[0015] It is not uncommon that, instead of trying to remove the sealing element as a whole, consumers choose to simply cut it, usually also with the help of a sharp instrument, such as the tip of a knife or a scissors. However, as usually one of the layers of the sealing element comprises a resilient plastic material, this may cause some difficulty for the consumer to be able to pierce the sealing element. The difficulty may be even greater in situations where the sealing element is quite thick, notably in containers in which the lid is not provided with an anti-tamper element, where the sealing element also serves to hinder the violation of the container, as previously mentioned.

[0016] In the situations mentioned above, in which consumers use some sharp instrument to assist in the removal of the sealing element, there is always a risk that accidents may occur, causing injury to consumers, something that is unfortunately not uncommon.

Petition 870180128395, of 10/09/2018, p. 35/86

4/50 [0017] As can be seen, the need to provide a sealing element in the mouth of the container nozzle, despite contributing to the preservation of the product, usually causes difficulties for consumers due to the need to remove the sealing element before using the product stored in the container.

[0018] In addition to the discomfort caused by the need to perform repeated operations to open the container (unscrew the cap from the mouthpiece, remove the sealing element from the mouthpiece of the mouthpiece and then screw the cap back on the mouthpiece), the operation of removing the element sealant often causes difficulties for consumers, and can even cause accidents.

[0019] Just do a quick search on complaints websites on the internet to see how very frequent complaints are in relation to this annoyance of having to remove the sealing element to be able to use the product contained in the containers, which shows that it is necessary to provide a solution to that problem. In the United States of America there is even a new expression to name this difficulty, “wrap rage”, which can be understood as the consumer's anger against the difficulty to open the packaging. And, really, it cannot be admitted that the consumer can even put his physical integrity at risk to perform a simple task of opening a package.

[0020] Some types of container lids are also known that also serve as sealing elements for the container. They are usually lids provided with a protruding element at the top, usually in the form of a cylinder trunk or cone trunk, which will later be used for product administration.

[0021] The protruding element has its upper end closed, in which case it will be necessary for the consumer to use a cutting instrument, a knife, for example, to cut the upper portion of the protruding element, thereby opening a ministering hole for the content of the container.

[0022] It is evident the high possibility of accidents occurring in this operation, especially if performed by children or older people. These covers can be provided in one piece or in two pieces joined by a tilting element, one of the pieces being the part that is applied to the nozzle and the other serving as a closing element.

[0023] In view of the problems previously reported, it becomes evident the need to provide sealed containers in which it is possible that consumers can easily perform the operation of opening the container without jeopardizing their physical integrity.

Petition 870180128395, of 10/09/2018, p. 36/86

5/50 [0024] The present invention provides a device for the automatic opening, in a single operation, of containers provided with sealing elements in the mouth of the pouring nozzle, which eliminates the need for the consumer to have to perform multiple actions to perform the opening the containers.

[0025] Furthermore, the present invention makes it possible for the sealing elements to be manufactured without the need to be thicker than desirable to serve only as a barrier element, eliminating the need for them to be more resistant to avoid accidental ruptures, as observed currently. These and other advantages will be immediately realized through the detailed description of the invention that will be made below.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS [0027] In the description that will follow in relation to embodiments of the invention, similar components will always be mentioned and indicated in the Figures by the same indicative numerals. Terms such as “top”, “bottom”, “vertical” and “horizontal” used in this description refer specifically to the position in which elements, parts, portions, regions, etc. are depicted in the Figures. Figures ΙΑ, 1B, 1C and 2 depict a first embodiment of the device for automatic opening of container 1 according to the present invention. As can be seen in the Figures, the device for automatic opening of the container 1 comprises a closing element la, a base element 1b and a locking device 6.

[0028] In the embodiment depicted in the Figures the closing element la, when in the closed position, depicted in Figure 1 A, fits into the base element lb, and both are connected together by means of a tilting connection element 7, as shown in more detail in Figure 2. There are variations of this type of tilting connection, which can be used interchangeably in conjunction with the present invention. In addition, any other type of connection means can be used to connect the closing element there to the

Petition 870180128395, of 10/09/2018, p. 40/86

9/50 base element lb, and there may even be no means of connection between them, in which case the connection between these two parts could be made by pressure or by screwing, for example.

[0029] The base element lb comprises a first side wall 11, in the form of an elongated cylindrical body, and a top element 10, circular in shape and whose edges are joined to the upper edge of the first side wall 11. A protruding ring central 2 is provided in the upper central portion of the top member 10, which surrounds a through hole 2a. The closing element la comprises a second side wall 9 in the form of an elongated cylindrical body and an upper element 8, circular in shape and whose edges are joined to the upper edge of the second side wall 9.

[0030] A protruding sealing element 4 is provided in the inner central portion of the upper element 8 of the closing element la. The sealing protruding element 4 is designed to lodge in the protruding ring 2 and to close the through hole 2a of the base element lb when the closing element la and the base element lb are closed.

[0031] Preferably the device for automatic opening of the container 1 is designed in such a way that the second side wall 9 of the closing element la and the first side wall 11 of the base element lb have substantially equal outer diameters when closed, as shown in Figure 1 A. In order for this to occur, the top element 10 of the base element 1b must be provided with a recess in the region of its edge where it connects to the first side wall 11, to form an annuliform region 10a. Thus, when the closing element la is in the closed position, the lower region of the second side wall 12 will fit into this annuliform region 10a, as can be seen in Figure 1B.

[0032] This feature is only intended to facilitate the manipulation of the device for automatic opening of container 1 by users, but it is not decisive for the functionality of the device. The configurations of the closing element la and the base element lb can be different from those depicted in the Figures, without, however, changing the functionality of these components for the proper operation of the device for automatic opening of the container 1. The device for opening automatic container 1 can even be provided without a closing element la as shown in the Figures, because even without this component the device for automatic opening of container 1 will operate normally, according to the principles of the invention, as if see later.

[0033] An internal thread 5 is provided in the inner portion of the first side wall 11 of the base element lb. In the embodiment shown in the Figures, the internal thread 5 comprises

Petition 870180128395, of 10/09/2018, p. 41/86

10/50 an internal thread of orientation to the right of three entries, depicted in the Figure by means of three threads of internal thread 5. However, the internal thread 5 can comprise a thread with any number of entries and, consequently, the invention is not limited to the use of an internal thread 5 of three inlets.

[0034] In the present description, a three-input thread was chosen only to make a description of the invention, although the use of a multiple-input thread is more suitable for the purposes of the invention, as will be seen below. The internal thread 5 can be indistinctly oriented to the right, as shown in the Figures, or oriented to the left. Hereinafter the expressions “internal thread 5” and “internal thread 5 threads” will be used as a common reference for this internal thread.

[0035] In the inner portion of the top element 10, a cutting device 3 is provided, which comprises a hollow protruding body whose upper portion is connected to the lower portion of the top element 10 in the region where the through hole 2a is located, the latter being a continuation of the hollow portion of the cutting device 3. The lower portion of the cutting device 3 is provided with a plurality of cutting elements 3a. In Figure 1B, this cutting device 3 does not appear in the section view, so that it can be viewed in its entirety.

[0036] The locking device 6 comprises an elongated substantially cylindrical body provided at its upper edge with a plurality of upper rupture elements 6a which are connected to the lower edge of the base element 1b, as can be seen in more detail in Figure 1C . A plurality of lower locking elements 6b is provided in the lower inner portion of the locking device 6. The lower locking elements 6b comprise flaps distributed circularly and spaced from each other, the lower portion of each flap being joined to the lower region of the locking device 6 and the body of each flap being tilted towards the geometric axis of the locking device 6. The lower locking elements 6b are designed so that they can undergo small radial bends towards the inner wall of the locking device 6.

[0037] Other configurations of lower locking elements 6b can be used and, therefore, the invention is not limited to the configuration depicted in Figures 1B and 1C. The function of the upper rupture elements 6a and the lower locking elements 6b will also be seen later in the description of the operation of applying the device for automatic opening of container 1 to a nozzle.

Petition 870180128395, of 10/09/2018, p. 42/86

11/50 [0038] Figure 3 shows a container 20, which is provided with a nozzle 12, shown in the Figure only by its upper part. The nozzle 12 comprises an elongated cylindrical body 13 provided with an external thread 14, in this case a three-inlet, right-hand thread, which comprises a lower thread 14a and an upper thread 14b, with a shaft 15 formed between these two fillets. It can be seen in Figure 3 that the upper thread 14b of the external thread 14 has an upper end 21 that extends over the upper ring 16, while the lower thread 14a has its upper end facing with the lower portion of the upper ring 16, to facilitate the screwing of the internal thread 5 threads on the shafts 15, as will be seen later [0039] The choice of an external orientation thread on the right, with three entries, is due exclusively because this is the configuration used in the internal thread threads 5 of the base element lb. The same comments presented above are valid here, in which the use of an orientation thread to the right of three entries is only one of the possibilities to carry out the invention, which evidently is not limited to the use of a thread of three entries, either for orientation right or left. Thus, the external thread 14 can be a thread with any number of entries, and its orientation can be indistinctly to the right, as shown in Figure 3, or to the left, as long as it is compatible with the thread used in the internal thread 5.

[0040] A sealing element 19 is affixed to the edge of the nozzle 12. The elongated cylindrical body 13 of the nozzle 12 is also provided in its outer portion with an upper ring 16, an intermediate ring 18 and a lower ring 17, located in the upper regions , intermediate and lower, respectively. The diameter of the upper ring 16 is smaller than the diameter of the intermediate ring 18, and the diameter of the intermediate ring 18 is smaller than the diameter of the lower ring 17, as can be seen in Figure 3.

[0041] Figures 4A, 4B, 4C and 4D show a sequence of a process for the application of the device for automatic opening of container 1 to the nozzle 12 of the container 20, provided with a sealing element 19. In order to facilitate the description from the process steps for the application of the device for automatic opening of container 1 in the nozzle 12 the internal thread 5 threads of the base element 1b that would be in the front portion of the device for automatic opening of the container 1 were preserved from the cut would appear in sectional views.

[0042] For the mere effect of simplifying the Figures, in the description of the process for the application of the device for automatic opening of container 1 to the nozzle 12, the tools used for this operation, which may be any, will not be represented.

Petition 870180128395, of 10/09/2018, p. 43/86

12/50 tools that are dedicated to this operation. The arrows W shown in Figures 4A, 4B, 4C and 4D indicate the direction of operation of applying the device for automatic opening of the container in the mouth 12 of the container 20.

[0043] The application of the device for automatic opening of container 1 to the nozzle 12 is made by means of a pressing process, a downward longitudinal movement by means of which the lower part of the device for automatic opening of container 1 is pressed against the part top of the nozzle 12, as shown in the Figures. In this process, slight interference may occur between some component parts of the device for automatic opening of container 1 and component parts of the nozzle 12 at the time of assembly.

[0044] Consequently, the device for automatic opening of container 1 must be made of a relatively resilient material, a plastic, for example, which will allow its elements located in regions where there is interference with elements of the nozzle 12 to undergo momentary elastic deformations. , which will allow the continuity of the application process of the device for automatic opening of container 1 in the nozzle 12.

[0045] In Figure 4A, a device for automatic opening of container 1 can be seen whose geometric axis is aligned with the imaginary geometric axis of the nozzle 12, in a position to start the operation of the device application for automatic opening of container 1 to the nozzle 12 In Figure 4B the device for automatic opening of container 1 is pictured in a position just before the start of its insertion in the nozzle 12. In Figure 4C the device for automatic opening of the container 1 is almost completely inserted in the nozzle 12. It is important observe in this Figure that the lower regions of the lower locking elements 6b of the locking device 6 initiate contact with the upper face of the intermediate ring 18.

[0046] With the continuity of the downward longitudinal movement of the device for automatic opening of container 1, in relation to the nozzle 12, the lower locking elements 6b of the locking device 6 will be pressed by the edge of the intermediate ring 18, and consequently will tend to tilt towards the internal wall of the locking device 6, which will allow the continuity of the downward longitudinal movement of the device for automatic opening of the container 1.

[0047] After the lower locking elements 6b of the locking device pass the intermediate ring 18 they will return to the initial position, in which they are projected towards the geometric axis of the locking device 6, as shown

Petition 870180128395, of 10/09/2018, p. 44/86

13/50 in Figure 4D, and shown in more detail in Figure 5, which shows Detail X indicated in Figure 4D. Consequently, the lower locking elements 6b will prevent longitudinal movements of the device for automatic opening of the container 1, which will then be held in that position.

[0048] The downward longitudinal movement of the device for automatic opening of container 1 will cease when the lower edge of the locking device 6 touches the upper surface of the lower ring 17, as shown in Figure 4D. Thereby the process of applying the device for automatic opening of container 1 to the nozzle 12 will be completed. Observe in Figure 4D that at the end of this downward longitudinal movement of the device for automatic opening of the container 1, the internal thread 5 threads are in a position in which they can be screwed to the thread 14 of the nozzle 12, as will be seen below. The container 20 will then be ready to be sent to points of sale and to be subsequently opened by a consumer.

[0049] Figures 6A, 6B, 6C and 6D are seen in top perspective, in partial section, showing a sequence of the procedure for opening container 20 by means of the device for automatic opening of container 1. In order to facilitate the description of the procedure, and also what occurred in the description of the process for applying the device to the nozzle 12 shown in Figures 4A, 4B, 4C and 4D, the internal thread threads 5 of the base element lb were maintained in Figures 6A, 6B , 6C and 6D, which would not appear in sectional views. The cutting device 3 also does not appear in the section views depicted in these Figures, so that it is possible to view it in its entirety.

[0050] In Figure 6A the device for automatic opening of container 1 is pictured in the position in which it will remain after being applied to container 20, an operation carried out in a factory. To start the container opening procedure 20, a consumer must apply a clockwise rotation movement to the upper portion of the device for automatic opening of container 1, formed by the closing element la and the base element lb, as indicated by the circle T in the Figures.

[0051] This clockwise rotation will cause the upper rupture elements 6a of the locking device 6 to rupture, as highlighted by the circles R in Figure 6B, and thus the assembly formed by the closing element la and the base element. lb will start to rotate clockwise. In the continuation of this clockwise rotation movement, the inlet ends 5a of the internal thread 5 threads will run along the upper face of the upper ring 16, until they meet the upper end 21 of the upper thread 14b of the thread 14, as can be seen in Figure 6B.

Petition 870180128395, of 10/09/2018, p. 45/86

14/50 [0052] Then, with the continuity of the rotation movement, the inlet end 5a of each internal thread 5 will begin to enter the shaft 15 of the external thread 14, as can be seen in Figure 6B. Following this rotation movement, the internal thread threads 5 will travel along the veins 15 of the external thread 14. This rotation movement will cause a downward axial displacement of the device for automatic opening of container 1, as indicated by the arrows Z in Figures 6B, 6C and 6D. The combination of the two movements, rotation and downward axial displacement, will cause the cutting elements 3a of the cutting device 3 to cut the sealing element 19 affixed to the upper edge of the nozzle 12, as can be seen in Figure 6C.

[0053] The rotational movement of the device for automatic opening of container 1 in a clockwise direction will end when the edge of the nozzle 12, to which the sealing element 19 is attached, touches the lower region of the top element 10 of the element base lb. This will cause a compression between the top element 10 of the base element 1b and the edge of the nozzle 12, which will contribute to a sealing in this area of compression, as can be seen in Figure 6D.

[0054] In Figure 7, an upper rupture element 6a can be seen which was broken at the beginning of the rotation movement of the device for automatic opening of container 1, in which part of it was attached to the inner portion of the upper edge of the locking element 6 , shown at the top of the drawing, and the remaining part was attached to the inner portion of the lower edge of the base element lb, shown at the bottom of the drawing, as indicated by the ellipses S in Figure 7.

[0055] At the end of the rotation movement of the device for automatic opening of container 1 in a clockwise direction, and of the resulting downward axial movement, the cutting elements 3a of the cutting device 3 will have already made the cutting of the sealing element 19, and consequently the the contents of the container 20 can be administered through the protruding hollow body of the cutting device 3 and the through hole 2a, just for this reason that the closing element la is tilted to release the administration of the product stored in the container 20 through the through hole 2a .

[0056] Preferably both the outer face of the second side wall 9 of the closing element la and the outer face of the first side wall 11 of the base element 1b of the device for automatic opening of the container 1 are both provided with means that increase the coefficient of friction thereof, consequently facilitating the manipulation of the device for automatic opening of container 1 by consumers.

Petition 870180128395, of 10/09/2018, p. 46/86

15/50 [0057] As seen, the process of opening container 20 described above requires the consumer to turn the device for automatic opening of container 1 clockwise. This may cause some confusion among consumers, as this is usually the direction of rotation for closing container lids, which mostly use right-hand threaded nozzles.

[0058] To prevent consumers from turning the device for automatic opening of container 1 in the wrong direction, it is necessary to place instructions on the top face of the closing element la so that the initial rotation is done in a clockwise direction, in order to guarantee the perfect functioning of the automatic container opening device 1. For example, a circular arrow with the tip indicating the correct direction of rotation can be used to open the package. In addition, a written instruction may be included that explains the correct direction of rotation.

[0059] However, there may still be situations in which inattentive consumers do not observe the instructions on the top face of the closing element la and, accustomed to turning lids counterclockwise to open containers, then perform a rotation on the device for automatic opening of container 1 in that counterclockwise direction. In order to avoid this problem, variations of the first embodiment of the device for automatic opening of container 1 will be shown below, which prevent this improper handling.

[0060] Figure 8A depicts a first variation of the device for automatic opening of container 1, in which the internal thread threads 5 are split, and comprise an upper section 5s and a lower section 5i. The intermediate portion of each internal thread 5 thread was removed, as can be seen in the Figure.

[0061] It can be seen in the Figure that a guide element 22, provided in the external portion of the elongated cylindrical body 13 of the nozzle 12, extends parallel to the upper edge of the nozzle

12. In this variation, the upper end 21 of the upper thread 14b of the external thread 14 extends to the guide element 22, as can be seen in Figure 8A. With this, a swing limiter 23 is formed between the upper end 21 of the upper thread 14b and the guide element 22.

[0062] If a consumer inadvertently applies a counterclockwise rotation to the upper portion of the device for automatic opening of container 1, formed by the closing element la and the base element lb, in that situation the lower sections 5i of the thread threads inner 5 will move on the upper face of the upper ring 16 until they engage the swing limiter 23, as shown in Figure 8B. Consequently, the

Petition 870180128395, of 10/09/2018, p. 47/86

16/50 consumers will no longer be able to turn the device for automatic opening of container 1 counterclockwise.

[0063] This will compel the consumer to direct his attention to the device for automatic opening of container 1, and consequently will notice the instructions as to the correct direction of rotation, being able to then rotate it in the correct direction (clockwise), to open the packaging .

[0064] Figure 9A depicts a front view in partial section of a second variation of the device for automatic opening of container 1, in which the upper ends 21 of the internal thread threads 5 extend beyond the upper ring 16 to a shorter extent than the extension seen in Figures 4A, 4B, 4C and 4D, and the lower thread 14a has its upper end facing with the lower portion of the upper ring 16, as can be seen in Figure 9A. In this variation, the locking elements 6b of the locking device 6 are designed in such a way that their upper ends maintain a clearance in relation to the lower face of the intermediate ring 18, as highlighted by the circles P in Figure 9A.

[0065] If a consumer inadvertently applies an anti-clockwise rotation to the upper portion of the device for automatic opening of container 1, formed by the closing element la and the base element lb, in that situation the inlet ends 5a of the fillets of internal thread 5 will approach the upper ends 21 of the upper threads 14b of the external thread 14.

[0066] When the entrance ends 5a contact the upper ends 21 of the upper threads 14b, as shown in Figure 9A, the consumer will perceive a resistance to the continuity of the rotation. If the consumer still persists in turning counterclockwise, as there is a gap between the upper ends of the locking elements 6b of the locking device 6 in relation to the lower face of the intermediate ring 18, this will allow the ends of inlet 5a of the internal thread threads 5 can pass over the upper ends 21 of the upper threads 14b, as shown in Figure 9B.

[0067] With the continuation of the undue rotation movement in a counterclockwise direction, the inlet ends 5a of the internal thread threads 5 will then pass over the upper ends 21 of the upper threads 14b, and with that the entrance ends 5a will return to travel the upper face of the upper ring 16, as shown in Figure 9C.

[0068] This passage of the entrance ends 5a over the upper ends 21 of the upper threads 14b will produce a noise, which should alert the consumer that something has not been done correctly. This should compel the consumer to direct his attention to the

Petition 870180128395, of 10/09/2018, p. 48/86

17/50 device for automatic opening of the container 1. Consequently, the consumer will notice the instructions for the correct direction of rotation, and can then rotate it in the correct clockwise direction to open the package.

[0069] Note that the clearance between the upper ends of the locking elements 6b of the locking device 6 in relation to the lower face of the intermediate ring 18 must be designed so that it is sufficient to allow the internal thread 5 threads to pass over the upper ends 21 of the upper threads 14b.

[0070] For that, it is necessary that this gap be larger than the vertical extension H that the upper ends 21 of the upper threads 14b go beyond the upper ring 16, as shown in Figure 9B. Therefore, in the event that the consumer applies a counterclockwise rotation to the upper portion of the device for automatic opening of container 1, the gap between the upper ends 21 of the upper fillets 14b in relation to the lower face of the intermediate ring 18 will always allow that the upper ends 21 of the upper threads 14b may extend beyond the upper ring 16, as can be seen by the circles T shown in Figure 9B.

[0071] If the noise of the passage from the inlet ends 5a over the upper ends 21 of the upper fillets 14b was not sufficient to show the consumer that something was not done correctly, the continuation of the counterclockwise rotation will cause the device for automatic opening of container 1 keeps rotating without linear displacement, as there will be no entanglement of the threads of internal thread 5 in the shafts 15 of the external thread 14, which will certainly indicate to the consumer that something is not being done correctly and it will finally lead you to observe the instructions on the upper face of the closing element la so that the rotation is done in a clockwise direction, to effect the opening of the packaging.

[0072] Figure 9D depicts a variation similar to the variation depicted in Figures 9A, 9B and 9C, in which the only difference is that the locking device 6 is provided in its lower portion with a circular flap 6e, which extends to from the lower end of the locking device 6 until it completely engages the lower ring 17, as can be seen in Figure 9D.

[0073] As in this variation of the invention there is a gap between the upper ends of the locking elements 6b of the locking device and the bottom face of the intermediate ring 18, this allows a certain degree of freedom in the longitudinal direction between the device for automatic opening of container 1 and the nozzle 12, and the circular flap 6e is intended to prevent anyone from inserting any object between the locking device 6 and the face

Petition 870180128395, of 10/09/2018, p. 49/86

18/50 upper of the lower ring 17, to unduly disconnect the device for automatic opening of container 1 from the nozzle 12.

[0074] Figure 10 depicts a third variation of the first embodiment of the device for automatic opening of container 1. In this variation, the internal thread 5 threads comprise a left-oriented thread, this being the only difference between the first embodiment and this variation .

Consequently, it will be necessary in this variation of the first embodiment of the invention that the nozzle 12 be provided with an external thread 14 with left orientation, as shown in Figure 10. Figure 11 depicts in more detail this nozzle with left orientation.

[0076] The process for applying the device for automatic opening of container 1 provided with internal thread threads 5 with left orientation to the nozzle 12 will be exactly the same as previously described in relation to Figures 4A, 4B, 4C and 4D, and the only difference in the process of opening the container 20 in relation to what was previously described in relation to Figures 6A, 6B, 6C and 6D is that in this variation the rotation for opening the container 20 must be done in a counterclockwise direction.

[0077] This is the great advantage in using this variation of the first embodiment of the invention, because in this case consumers will have to rotate the device in a direction of rotation (counterclockwise) to which they are accustomed to execute to open packages with screw caps. , in which mostly right-hand threads are used.

[0078] This means that, although in this variation of the invention a left-hand thread is used, even so consumers will hardly notice any differences in relation to the commonly used caps. In other words, as usually the action of opening a lid is associated with a counterclockwise rotation, there should be no dismay on the part of consumers about the fact that they have to apply a counterclockwise rotation to the device for automatic opening. of container 1 to open container 20.

[0079] It is reiterated that, as previously mentioned, in the present description of the invention the expression "open the container" means to break the sealing element that is applied to the mouthpiece of the container to protect its contents, in order to allow this contents can be removed from inside the container. Note that, according to the principles of the invention, after the consumer has opened the packaging procedure, there is no need to perform any further action, and the product stored in the container can be used immediately.

Petition 870180128395, of 10/09/2018, p. 50/86

19/50 [0080] That is, it is a one-step procedure, differently from what is observed today, in which the consumer needs to perform more steps, usually three, in order to start using the product stored in the container , namely, the steps of unscrewing and removing the cap from the nozzle, then manually removing the sealing element, and screwing the cap back on the nozzle.

[0081] It is also important to mention that this third variation can be combined with any of the variations of the first embodiment of the invention previously described, making only the necessary adaptations due to the use of a left-hand thread.

[0082] Figures 12A, 12B and 12 C show frontal views, in partial section, of a fourth variation of the device for automatic opening of the container shown in Figures ΙΑ, 1B, lCe2. The difference observed in this variation is the provision of a locking device 6 'of less longitudinal extension, as can be seen in the Figures, due to a partial screwing of the internal thread 5 threads in the veins 15 of the external thread 14, which will be perceived through the description that will be made in the next paragraphs.

[0083] As can be seen in more detail in Figure 12A, the locking device 6 'comprises an elongated substantially cylindrical body provided at its upper edge with a plurality of upper rupture elements 6a' which are connected to the lower edge of the locking element. base lb. A plurality of lower locking elements 6b 'is provided in the lower inner portion of the locking device 6'.

[0084] The device depicts a device for automatic opening of container 1 with the same characteristics described above in relation to the device shown in Figures 1 A, 1B, 1C and 2, as well as the same nozzle 12 previously described in relation to these same Figures ΙΑ, 1B, 1C and 2. Consequently, there is no need to repeat here the description of the constituent parts of both.

[0085] And the same observations are valid here regarding the characteristics of the internal thread 5 and the external thread 14, which in the Figures comprise multiple input threads with right orientation, however, single or multiple input threads can be used, with right or left orientation.

[0086] The application of this variation of the device for automatic opening of container 1 to the nozzle 12 is made at the factory, by means of an equipment not pictured in the Figures, which performs a sequential pressing and rotation process. Initially, a downward longitudinal movement is employed to the device for automatic opening of the container

Petition 870180128395, of 10/09/2018, p. 51/86

20/50

1, as indicated by the arrow M in Figure 12A, whereby the lower part of the device for automatic opening of the container 1 is pressed against the upper part of the nozzle 12, until the lower regions of the lower locking elements 6b 'touch the upper region of the intermediate ring 18.

[0087] Then, a rotational movement is applied to the device for automatic opening of container 1, as indicated by the circle N in Figure 12B, with which the internal thread threads 5 of the base element lb will engage in the shafts 15 of the external thread 14 of the nozzle 12. With the continuation of this rotational movement, the lower locking elements 6b 'will be forced against the edge of the intermediate ring 18, and consequently will retract towards the inner wall of the locking device 6', until they pass fully the edge of the intermediate ring 18. From that moment on, the lower locking elements 6b 'will make it difficult to apply any rotational movements of the device for automatic opening of the container 1 to unscrew it from the nozzle 12.

[0088] The rotation movement for screwing the device for automatic opening of container 1 in the nozzle 12 will cease when the lower region of the locking device 6 'touches the upper region of the lower ring 17, as can be seen in Figure 12C. With that, the container will be ready to be sent to points of sale. Note that the thread of the internal thread 5 threads in the shafts 15 of the external thread 14 was partial.

[0089] When a user is going to open the package, he must apply a rotational movement to the device for automatic opening of container 1 with sufficient torque to break the upper rupture elements 6a ', with which the internal thread 5 threads will continue to travel the threads 15 of the external thread 14, and this screwing motion will cause the cutting elements 3a of the cutting device 3 to break the sealing element 19 of the nozzle 12, opening the package and allowing the product stored inside the container to be served .

[0090] The reduction in the longitudinal extension of the locking device 6 ', in comparison with the longitudinal extension of the locking device 6, is due to the characteristic of having a partial screwing of the threads of internal thread 5 in the shafts 15 of the external thread 14.

[0091] The lower locking elements 6b 'must be designed in such a way as to offer sufficient strength to make any attempt to unscrew the device for automatic opening of container 1 in the nozzle 12 quite difficult, especially if threads of right orientation are used in the fillets. internal thread 5 and external thread 14.

Petition 870180128395, of 10/09/2018, p. 52/86

21/50

In this case, as the normal habit of consumers is to apply a counterclockwise movement in a lid, to open a container, the great difficulty that the user would have to perform such a counterclockwise rotation movement to the device for automatic container opening 1 would serve to draw your attention to the orientations in the upper region of the closing element la, which would indicate the execution of a correct rotational movement in a clockwise direction, to open the container.

[0092] If a nozzle 12 as shown in Figure 11 was used, provided with an external thread with a left orientation, in this case, to open the container the user should then apply a counterclockwise rotational movement to the device for automatic opening of container 1. As this is the direction of rotation usually used to open container lids with right-hand thread, the most common, in this case users would have no difficulty performing the rotation movement in the correct direction, and they would probably not even notice that the container nozzle is provided with a left-hand thread.

[0093] Figures 13A and 13B depict, respectively, a top perspective view, and a top perspective sectional view of a fifth variation of the device for automatic opening of container 1, in which the base element lb is provided with a suction nozzle 24, which comprises a hollow body that extends above the base element 1b and surrounds the through hole 2a. In this variation, the suction nozzle 24 is provided at its upper end with a nozzle ring 24a, and the protruding sealing element 4 of the upper element 8 of the sealing element la is designed to lodge in the nozzle ring 24a and close the opening orifice. passage 2a of the base element lb when the closing element la and the base element lb are closed.

[0094] Containers provided with suction nozzles are normally used to store liquids that are usually consumed by consumers when they are on the move, cases of cyclists, long-distance runners or even people who prefer to consume the product stored in the container while on the move.

[0095] In this fourth variation of the first embodiment of the invention the installation of the device for automatic opening of the container 1 and the opening of the container 20 are carried out in exactly the same way as described above, since all the other components of this variation are the same as previously described.

[0096] Note that this fourth variation can be combined with any of the variations of the first embodiment of the invention described above. In the case of

Petition 870180128395, of 10/09/2018, p. 53/86

22/50 combination of the third variation with the fourth variation will only be necessary to make the necessary adaptations, due to the use of a thread with left orientation.

[0097] Figures 14A and 14B depict, respectively, a front view in partial section and an upper perspective view in partial section, showing details of a nozzle adapter device 25 intended to serve as an interface for the application of a device for opening automatic container 1 in a nozzle 26 of a container provided with an external thread different from the internal thread of the device for automatic container opening. A sealing element 19 is affixed to the edge of the nozzle 26. The upper outer region of the nozzle 26 is provided with an external thread 30, with a retaining ring 33 being located below the external thread 30.

[0098] The device for automatic opening of container 1 shown in Figures 14A and 14B is substantially similar to what has been described in relation to Figures 4A, 4B, 4C and 4D, and for that reason it will not be necessary to repeat this description here. Any of the variations of the device for automatic opening of container 1 described above could have been depicted in Figures 14A and 14B, which would normally operate in conjunction with the mouthpiece adapter device 25, which means that there is no limitation on the use of any device type for automatic opening of container 1 in conjunction with nozzle adapter device 25.

[0099] The lower external region of the nozzle 26 is provided with a base ring 28, larger in diameter than the retaining ring 33. The external thread 30 shown in the Figures has a different configuration from the internal thread 5 of the device for automatic opening of the container 1 , and in the Figures a single entry thread with right orientation is depicted, although other thread configurations can be used, such as, for example, a multiple entry thread and / or a left orientation thread.

[0100] As can be seen in Figures 14A, 14B and 14C, the nozzle adapter device 25 comprises an upper portion 25s rigidly connected to a lower portion 25i, of larger diameter, both substantially cylindrical portions. The upper outer region of the upper portion 25s is provided with a protruding ring 25c, located near the upper edge of the mouthpiece adapter device 25, and an external thread 27. The external thread 27 comprises a lower thread 27a and an upper thread 27b, and a shaft 27c is formed between the lower thread 27a and the upper thread 27b. In the Figures a three-inlet thread is shown, with orientation to the right, for mere illustrative effect. However, a thread with any number of entries can be used, according to the design convenience.

Petition 870180128395, of 10/09/2018, p. 54/86

23/50 [0101] As seen in Figure 14A, the upper thread 27b of the external thread 27 has an upper end 31 that extends beyond the protruding ring 25c, in order to facilitate the screwing of the external thread threads 5 of the opening device automatic container 1 on the shafts 27c, as will be seen later, while the lower thread 27a has the upper end facing with the lower portion of the protruding ring 25c.

[0102] An internal thread 29 is provided in the inner region of the upper portion 25s of the mouthpiece adapter device 25, as can be seen in Figures 14B, 14C and 14D. This internal thread 29 is dimensioned to fit the external thread 30 of the nozzle 26, as will be seen later. For the sole purpose of facilitating visualization, an internal thread 29 of an entry is depicted in the Figures, although a multiple entry thread could be depicted.

[0103] The lower internal region of the lower portion 25i is provided with a plurality of lower locking elements 25a, each located in front of openings 25b formed in the lower portion 25i, as can be seen in the Figures. The lower locking elements 25a are similar to the lower locking elements 6b of the locking device 6, and comprise circularly distributed and spaced flaps, the lower portion of each flap being joined to the lower region of the lower portion 25i of the mouthpiece adapter device. 25, and the body of each flap being tilted towards the geometric axis of the nozzle adapter device 25.

[0104] The lower locking elements 25a are designed so that they can undergo small radial bends towards the inner wall of the nozzle adapter device 25 when it is connected to the nozzle 26, as will be seen later. Other locking means can be used to replace the lower locking elements 25a, provided that they are able to lock the nozzle adapter device 25 into the nozzle 26.

[0105] The device for automatic opening of container 1 must be applied to the nozzle adapter device 25 by means of a pressing process, a downward longitudinal movement in which the bottom part of the device for automatic opening of container 1 is pressed against the part top of the nozzle adapter device 25, which causes a forced assembly between them. This application will be made in a factory.

[0106] Similar to what occurred in the application process of the device for automatic opening of container 1 in the nozzle 12, in relation to Figures 4A, 4B, 4C and 4D, in this application process by pressing the device for automatic opening of

Petition 870180128395, of 10/09/2018, p. 55/86

24/50 container 1 against the upper part of the nozzle adapter device 25 there will be a slight interference between some component parts of the device for automatic opening of container 1 and component parts of the nozzle adapter device 25. Therefore, the same observations made here previously.

[0107] In this process of applying the device for automatic opening of container 1 on the nozzle adapter device 25 the lower locking elements 6b of the locking device 6 will be pressed by the lower portion 25i of the nozzle adapter device 25, and consequently will tend to tilt towards the internal wall of the locking device 6, which will allow the continuity of the downward longitudinal movement of the device for automatic opening of the container 1. Figure 15 shows a top perspective view in cross-section in which the application of the device for automatic opening of container 1 in nozzle adapter device 25.

[0108] Preferably the lower locking elements 6b of the locking device 6 should fit into the openings 25b formed in the lower portion 25i of the nozzle adapter device 25, which are in front of the lower locking elements 25a. Thereby the lower locking elements 6b and the lower locking elements 25a will be facing, as shown in Figure 15.

[0109] A front view of the mouthpiece adapter device 25 is shown in Figure 16 showing an alternative configuration for the lower portion 25i of the mouthpiece adapter device 25, which in this configuration is not provided with openings 25b. In this configuration, the upper region of the lower portion 25i is provided with a protruding ring in relation to the lower region of the lower portion 25i, thereby forming a retaining edge 25r, which will serve to retain the lower locking elements 25a as soon as they pass the retaining edge 25r, as shown in Figure 16, and especially in the K circles.

[0110] Figure 17 shows the set formed by the device for automatic opening of container 1 and the adapter device of nozzle 25, both already properly assembled, in a position immediately before the start of application of the set to nozzle 26. This application will be made in a manufacturing facility by means of a rotating applicator, not shown in Figure 17, which applies a clockwise rotation to the assembly, as indicated by circle G in the Figure.

[0111] Similar to what occurred in the process of applying the device for automatic opening of container 1 in the nozzle adapter device 25, or in the nozzle 12, in this case in relation to Figures 4A, 4B, 4C and 4D, in the process of applying the assembly comprising the device for automatic opening of the container 1 and the adapter device

Petition 870180128395, of 10/09/2018, p. 56/86

25/50 of nozzle 25 against the nozzle 26 there will be a slight interference between some component parts of the nozzle adapter device 25 and component parts of the nozzle 26. Therefore, the same observations made above are valid here.

[0112] Consequently, in this process the lower locking elements 25a of the nozzle adapter device 25 will be pressed by the edge of the retaining ring 33 and will tend to tilt towards the inner wall of the nozzle adapter device 25, which will allow the movement to continue longitudinal descending of the set formed by the device for automatic opening of container 1 and the nozzle adapter device 25, until the process is finished.

[0113] Figure 18 shows the set formed by the device for automatic opening of the container 1 and the adapter device of nozzle 25 already properly applied to the nozzle 26. Observe how the lower locking elements 25a of the adapter device of nozzle 25 exceeded the retaining ring 33 from the nozzle 26 at the end of the process of applying the assembly to the nozzle 26. With that, the container 20 will be ready to be sent to points of sale and to be subsequently opened by a consumer.

[0114] The operation of opening the container 20 will be carried out in the same manner as described previously in relation to Figures 6A, 6B, 6C and 6D, and for that reason the description of this procedure will not be repeated. Therefore, the same observations made regarding the process of opening the container 20 by means of the device for automatic opening of the container 1 applied to the nozzle 12 are valid here.

[0115] Figures 19A, 19B and 19C depict an exploded front view, partial section, a top perspective view, partial section, and a front view, respectively, in which an alternative embodiment of a mouthpiece adapter device is shown 35 to be used in conjunction with the automatic container opening device 1. The mouthpiece adapter device 35 comprises an upper portion 35s, a middle portion 35m and a lower portion 35i.

[0116] In the outer portion of the upper portion 35s, a protruding ring 35c, located at the upper part, is provided. An external thread 37 is also provided, similar to the external thread 27 of the nozzle adapter device 25 of the previous embodiment. The external thread 37 comprises a lower thread 37a and an upper thread 37b, a shaft 37c being formed between the threads 37a and 37b. A three-threaded thread is shown in the Figures for illustrative purposes. It is important to mention that a thread with any number of entries can be used, according to the design convenience.

Petition 870180128395, of 10/09/2018, p. 57/86

26/50 [0117] The upper thread 37b of the external thread 37 has an upper end 32 that extends beyond the protruding ring 35c, in order to facilitate the screwing of the external thread threads 5 of the device for automatic opening of the container 1 in the 37c shafts , as will be seen later, while the lower thread 37a has its upper end facing with the lower portion of the protruding ring 35c.

[0118] As shown in Figures 19A, 19B and 19C, an edge 34 is provided in the lower region of the upper portion 35s of the mouthpiece adapter device 35. The middle portion 35m has a trunk-conical shape and its upper portion is connected to the region lower edge of that edge 34, while its lower region is connected to the upper region of the lower portion 35i. In the region connecting the middle portion 35m with the lower region of the rim 34 there is a radial spacing intended to engage the lower locking elements 6b of the device for automatic opening of container 1 when it is applied to the mouthpiece adapter device 35, as will be seen later.

[0119] The middle portion 35m is provided with a plurality of radial openings 35a spaced apart and circumferentially distributed. An internal thread 36 of an inlet is provided in the inner portion of the lower portion 35i of the nozzle adapter device 35. This inner thread 36 is dimensioned to thread with the outer thread 30 of the nozzle 26, as will be seen later.

[0120] A plurality of lower locking elements 35b are provided in the lower inner region of the lower portion 35i, similar to the lower locking elements 25a of the mouthpiece adapter device 25, the lower locking elements 35b comprising flaps distributed circularly and spaced apart from each other , the lower portion of each flap being joined to the lower region of the lower portion 35i of the nozzle adapter device 35, and the body of each flap being tilted towards the geometric axis of the nozzle adapter device 35. The lower locking elements 35b are designed so that they can undergo small radial flexions towards the inner wall of the nozzle adapter device 35 when it is connected to the nozzle 26, as will be seen later.

[0121] The use of the nozzle adapter device 35 makes it necessary to lengthen the cutting device 3 of the device for automatic opening of the container 1, in comparison with the cutting devices 3 of the variations of the invention described above, to compensate for the increase in height in the assembly formed by the nozzle adapter device 35 and the device for automatic opening of container 1, when this is applied to the nozzle 26, as will be seen later.

Petition 870180128395, of 10/09/2018, p. 58/86

27/50 [0122] The device for automatic opening of the container 1 must be applied to the nozzle adapter device 35 by means of a pressing process, a downward longitudinal movement in which the bottom part of the device for automatic opening of the container 1 is pressed against the top of the nozzle adapter device 35, which causes a forced assembly between them. This application will be made in a factory.

[0123] Similar to what occurred in the application process of the device for automatic opening of container 1 in the nozzle 12, in relation to Figures 4A, 4B, 4C and 4D, in this application process by pressing the device for automatic opening of container 1 against the upper part of the nozzle adapter device 35 there will be a slight interference between some component parts of the device for automatic opening of container 1 and component parts of the nozzle adapter device 35. The same observations made above are therefore valid here.

[0124] In this process of applying the device for automatic opening of container 1 in the nozzle adapter device 35, the lower locking elements 6b of the locking device 6 will be pressed by the edge 34 of the nozzle adapter device 35, and consequently will tend to tilt in towards the inner wall of the locking device 6, which will allow the continuity of the downward longitudinal movement of the device for automatic opening of the container 1.

[0125] At the end of that downward longitudinal movement to apply the device for automatic opening of the container 1 to the mouthpiece adapter device 35 the lower locking elements 6b will override the edge 34, and will cause the device to automatically retain the opening of the container 1 in the device nozzle adapter 35. Figure 20 shows a view in which the application of the device for automatic opening of container 1 can be seen in the nozzle adapter device 35, both already properly assembled.

[0126] In this process there will be a slight interference between some component parts of the device for automatic opening of container 1 and component parts of the mouthpiece adapter device 35 at the time of assembly. Therefore, the same observations made in relation to the application process of the device for automatic opening of container 1 in the mouthpiece adapter device 25 or in the mouthpiece 12, in the latter in relation to Figures 4A, 4B, 4C and 4D, are valid here. Preferably the lower locking elements 6b of the locking device 6 should fit into the radial openings 35a of the middle portion 35m of the mouthpiece adapter device 35, as shown in Figure 20.

Petition 870180128395, of 10/09/2018, p. 59/86

28/50 [0127] Figure 21 shows the assembly formed by the device for automatic opening of container 1 and the nozzle adapter device 35, both already properly assembled, in a position immediately before the start of the application to the nozzle 26. This application will be made in a factory installation by means of a rotating applicator, not shown in Figure 21, which applies a turn to the set, in this case a clockwise turn, as indicated by circle J in the Figure.

[0128] Similar to what occurred in the process of applying the device for automatic opening of container 1 in the nozzle adapter device 35, or in the nozzle 12, in the latter in relation to Figures 4A, 4B, 4C and 4D, in the process of applying the assembly comprising the device for automatic opening of the container 1 and the nozzle adapter device 35 against the nozzle 26 there will be a slight interference between some component parts of the nozzle adapter device 35 and nozzle component parts 26. Therefore, the same observations apply here previously made.

[0129] Consequently, in this process the lower locking elements 35b of the nozzle adapter device 35 will be pressed by the edge of the retaining ring 33 and will tend to tilt towards the inner wall of the nozzle adapter device 35, which will allow the movement to continue longitudinal descending of the set formed by the device for automatic opening of container 1 and the nozzle adapter device 35, until the process is finished.

[0130] Figure 22 is a top perspective view, in section, showing the assembly formed by the device for automatic opening of the container 1 and the nozzle adapter device 35 already properly applied to the nozzle 26. Observe how the lower locking elements 35b of the nozzle adapter device 35 overtook the retaining ring 33 of the nozzle 26 at the end of the process of applying the assembly to the nozzle 26. With that, the container 20 will be ready to be sent to points of sale, and to be subsequently opened by a consumer.

[0131] The operation of opening the container 20 will be carried out in the same way as described previously in relation to Figures 6A, 6B, 6C and 6D, and for that reason the description of this procedure will not be repeated. The same observations made regarding the process of opening the container 20 by means of the device for automatic opening of the container 1 applied to the nozzle 12 are valid here.

[0132] The external thread 27 of the nozzle adapter device 25, shown in Figures 14A, 14B, 14C and 14D, and the external thread 37 of the nozzle adapter device 35, shown in Figures 19A and 19B, can both be oriented threads on the left if a

Petition 870180128395, of 10/09/2018, p. 60/86

29/50 device for automatic opening of container 1 whose internal thread 5 is a left-hand thread.

[0133] Figures 23A, 23B, 23C and 24 depict views of a further embodiment of the invention, showing a device for automatically opening container 41 to be applied to a nozzle 47 of a container 51. The nozzle 47 comprises an elongated cylindrical body 48, a first upper ring 49 and a second lower ring 50, larger in diameter than the first upper ring 49. A sealing element 19 is adhered to the upper edge of the nozzle 47. The connection between the nozzle 47 and the device for automatic opening of container 41 is of the bayonet type, as will be seen later.

[0134] The device for automatic opening of the container 41 comprises a closing element 41a, a base element 41b and a guide and locking device 46. In Figure 24 the closing element 41a is in the open position, and the connection between the base element 41b and the closing element 41a is made by means of a tilting connecting element, not shown in the Figure, a connection similar to that used between the closing element la and the base element lb previously described in relation to the Figures 1 A, 1B and 1C and 2.

[0135] The base element 41b comprises a first side wall element 54 and a top member 55 whose edges are joined to the upper edge of the first side wall element 54. A central protruding ring 39 is provided in the upper central portion of the member top 55, which surrounds a through hole 39a. An external thread 45 is provided in the lower external portion of the first side wall element 54 of the base element 41b. In the Figures, an external thread with three entries is shown, merely as an example, as this thread may have other configurations. The external thread 45 threads can be seen in the Figures, and henceforth the expressions "external thread 45" and "external thread 45 threads" to refer to the same thread.

[0136] The closing element 41a comprises a second side wall element 56 in the form of an elongated cylindrical body and an upper member 57, circular in shape and whose edges are joined to the upper edge of the second side wall element 56. One element sealing protrusion 40 is provided in the inner central portion of the top member 55 of the sealing element 41a. The protruding sealing element 40 is designed to lodge in the protruding ring 39 and to close the through hole 39a of the base element 41b when the closing element 41a and the base element 41b are closed.

[0137] The guide and locking device 46, portrayed in partial section in Figures 23 A, 23B, 23C and 24 comprises an elongated cylindrical body whose upper inner portion is provided with an internal thread 44, in the Figure a three-thread is shown entries that

Petition 870180128395, of 10/09/2018, p. 61/86

30/50 comprises a lower thread 44a and an upper thread 44b, with a shaft 44c formed between these two threads. In order to facilitate the description of the device for automatic opening of container 41 and its use for opening of container 51, the threads of the internal thread 44 of the guide and locking device 46 were kept in the Figures, which would not appear in a view in section.

[0138] The upper ends 44d of the upper threads 44b extend above the upper ends of the lower threads 44a, with the purpose of facilitating the screwing of the external thread threads 45 in the shafts 44c. Reinforcement flaps 46d are provided on the upper edge of the guide and locking device 46, located in the regions where the upper ends 44d of the upper threads 44b are extended, with the purpose of providing support for the upper ends 44d at the moment when the ends of inlet 45a of the external thread fillets 45 touch the upper ends 44d, as will be seen later.

[0139] As can be seen in Figure 23C, a plurality of lower locking elements 46b is provided in the lower region of the inner portion of the guide and locking device 46, which comprise flaps distributed circularly and spaced from each other, the lower portion of each flap being joined to the lower region of the inner portion of the guide and locking device 46, and the body of each flap being tilted towards the geometric axis of the guide and locking device 46.

[0140] A plurality of upper rupture elements 46a connects the upper region of the guide and locking device 46 to the lower edge of the base element 41b, as outlined by circle F in Figure 23C. A plurality of guide fins 46c can also be seen in the Figure, provided in the lower inner portion of the guide and locking device 46. These guide fins 46c are optional, and serve to facilitate the insertion of the guide and locking device 46 in the mouthpiece 47, positioning it correctly.

[0141] For mere descriptive effect in the Figures, the thread 45 provided on the lower external portion of the first side wall element 54 of the base element 41b, and the internal thread 44 provided on the upper internal portion of the guide and locking device 46 comprise a three inlet thread. The same comments made above are valid here that the use of a right-hand thread, with three inlets, is only one of the possibilities to carry out the invention, which is evidently not limited to the use of a three-inlet thread.

[0142] A cutting device 43 is provided in the lower central portion of the top member 55 of the base element 41b, the cutting device 43 comprising a body

Petition 870180128395, of 10/09/2018, p. 62/86

31/50 hollow protruding whose upper portion is connected to the lower central portion of the top member 55 in the region where the through hole 39a is, the latter being a continuation of the hollow portion of the cutter 43. The lower portion of the cutter 43 is provided with a plurality of cutting elements 43a.

[0143] In Figures 25A and 25B, the device for automatic opening of container 41 is in a position immediately prior to the start of its application to nozzle 47. The application of the device for automatic opening of container 41 to nozzle 47 will be done by means of a process of pressing the lower portion of the device for automatic opening of container 41 against the upper portion of the nozzle 47, operation performed in a factory installation by means of an applicator not shown in Figures 25A and 25B.

[0144] Figure 26A is a front view in partial section showing the device for automatic opening of the container 41, already properly applied to the nozzle 47. Observe how the lower locking elements 46b of the guide and locking device 46 overtook the first upper ring 49 at the end of the application process of the device for automatic opening of container 41 to the nozzle 47. With that, the container 51 will be ready to be sent to points of sale, and to be subsequently opened by a consumer.

[0145] When a consumer is going to open the container 51, he must apply a clockwise rotation to the set formed by the closing element 41a and the base element 41b. This will cause the upper rupture elements 46a to rupture, and consequently the inlet ends 45a of the outer thread threads 45 will be guided by the upper ends 44d of the upper threads of the inner thread 44 to start screwing in the shafts 44c. In Figure 26B, the threads of external thread 45 that are already screwed into the shafts 44c of the internal thread 44 can be seen.

[0146] With the continuation of the clockwise rotation movement, the set formed by the closing element 41a and the base element 41b, in addition to rotating, will also execute a concomitant linear downward movement, and thus the cutting elements 43a of the device cutting 43 will perform the operation of breaking the sealing element 19, to open the container 51.

[0147] The rotational movement of the assembly formed by the closing element 41a and the base element 41b in a clockwise direction will end at the moment when the inner portion of the top member 55 of the base element 41b touches the edge of the nozzle 47, where the sealing element 19. is fixed. This will cause a compression between the top member 55 of the base element 41b and the edge of the nozzle 47, which will contribute to a sealing in this compression area.

Petition 870180128395, of 10/09/2018, p. 63/86

32/50 [0148] Figure 27 is a partial sectional perspective view showing a variation of the device for automatic opening of the container 41, in which the only difference in relation to the device for the automatic opening of the container 41 depicted in Figures 23A, 23B, 23C and 24 is that the lower region of the guide and locking device 46 is provided with an internal thread 52. This variation of the device for automatic opening of the container 41 can be used in containers provided with threaded nipples.

[0149] The nozzle 26 of the container 20 shown in Figure 27 is provided with a single entry thread with right orientation. The choice of this type of thread was made only to exemplify this variation of the invention, since the container 20 may be provided with a thread with more than one entrance and the thread orientation may also be on the left. The internal thread 52 of the device for automatic opening of the container 41 must be screwed into the thread 30 of the threaded nozzle 26 by means of a rotating applicator, an operation carried out at the factory.

[0150] The opening operation of the container 20 will be carried out by the users in the same manner as previously described. Users are unlikely to even notice the differences between the modalities of devices for automatic opening of containers 41 used in a container, whether depicted in Figure 27 or depicted in Figures 23A, 23B, 23C and 24.

[0151] Figures 28A and 28B in perspective depict alternative configurations for the guide and locking device 46 of the device for automatic opening of container 41. In Figure 28A the guide and locking device 46 is not provided with the reinforcement flaps 46d (shown in the embodiment of Figures 25A and 25B). In this case, the upper ends 44d of the upper fillets 44b must be designed in such a way as to be able to withstand the stress to which they will be subjected at the moment when the opening operation of the container starts, when they will come in contact with the inlet ends 45a of the external thread fillets 45.

[0152] In Figure 28B the elongated cylindrical body of the guide and locking device 46 is extended so as to provide support for the upper ends 44d of the upper threads 44b. Although this alternative configuration of the guide and locking device 46 is more complex to manufacture, it has the advantage of also providing protection for the external thread fillets 45, which are less exposed. This avoids the possibility of damage to the external thread fillets 45 in the event of impacts from eventual falls, notably on shelves in markets where products are displayed for sale.

[0153] Combinations of internal thread configurations 44 and external thread fillets 45 different from those depicted in the previous Figures referring to the

Petition 870180128395, of 10/09/2018, p. 64/86

33/50 device for automatic opening of container 41. For example, it is possible to invert the location of the internal threads 44 and the threads of external thread 45 without changing the way of operation of the modalities of the invention relating to the device for automatic opening of the container 41.

[0154] Figure 29A shows a partial partial front view of the device for automatic opening of container 41 in which the lower thread 44a and the upper thread 44b of the thread 44 are applied to the upper region of the inner portion of the guide and locking device 46 , as previously described, but it is possible to reverse this configuration.

[0155] Figure 29B depicts a front partial view of the device for automatic opening of the container 41 in which a device for automatic opening of the container 41 is depicted in which the outer portion of the lower region of the base element 41b is provided with a external thread 144, which comprises a lower thread 144a and an upper thread 144b, with a shaft 144c formed between these two threads, wherein the lower ends 144d of the lower threads 144a extend below the lower ends of the upper threads 144b. An internal thread 145 is provided in the upper region of the internal portion of the guide and locking device 46.

[0156] In Figures 29A and 29B, for the sake of descriptive effect, it was decided to use a three-input thread. The same comments previously made are valid here, in which threads 144 and 145 can be single or multiple entries, in which case the internal thread 145 will comprise a plurality of internal thread threads.

[0157] If the configuration shown in Figure 29B is used in the device for automatic opening of the container 41, the reinforcement tabs 46d on the upper edge of the guide and locking device 46 will, when used, be located in the regions where the ends of the internal thread threads 145 are extended above the upper edge of the guide and locking device 46.

[0158] Another difference in relation to the configuration depicted in Figure 29A will be noticeable at the time of opening the container. In that case, when a rotation movement is applied to the device for automatic opening of the container 41, the lower ends 144d of the lower threads 144a of the external thread 144 will touch the upper ends of the internal thread threads of the thread 145, which, in continuity of the rotational movement, will cause these internal thread threads of thread 145 to become threaded on the threads 144c of the external thread 144.

Petition 870180128395, of 10/09/2018, p. 65/86

34/50 [0159] The operation of opening the container will be performed regardless of whether any of these two configurations are used, as this operation will occur in the same way, whatever the configuration used. A user would probably not notice the difference between these two settings. The choice of the thread configuration to be used will be a design option and, as shown above, only the necessary adaptations must be made so that the device for automatic opening of the container 41 can be used without distinction from the configuration to be used.

[0160] Although in the previously described modalities of the device for automatic opening of container 41, right-hand threaded figures have been portrayed in the Figures, there is no impediment to the use of left-handed threads, as previously mentioned in relation to the embodiments described above.

[0161] Therefore, the same observations previously presented are valid here, emphasizing that if a left-hand thread is used, it will only be necessary to make the necessary adaptations so that the automatic container opening device 41 can be used without no difficulty, whatever the configuration adopted. Figures 30A and 30B are front views in partial section showing devices for automatic opening of containers 41 provided with left-facing threads, similar to those depicted in Figures 29A and 29B.

[0162] Figures 31A and 31B portray a partial partial front view and a partial partial frontal perspective view, in which an additional embodiment of a device for automatic container opening 61 is shown in accordance with the precepts of the present invention. As can be seen in the Figures, the device for automatic opening of the container 61 comprises a closing element 61a, a base element 61b and a locking device 62.

[0163] In the embodiment shown in the Figures the closing element 61a is in the closed position, engaged with the base element 61b. Preferably, both are connected to each other by means of a tilting connection element, not shown in the Figures. This type of tilting connection between base elements and closing elements is well known in the art, with variations thereof, which can be used interchangeably in conjunction with the present invention. Any other connection means can be used to connect the closing element 61a to the base element 61b, and there may even be no connection means between them, in which case the connection between these two parts could be made by pressure, or by tangling, for example.

Petition 870180128395, of 10/09/2018, p. 66/86

35/50 [0164] Similar to the devices for automatic opening of container 1 and 41 described above, the base element 61b comprises a first side wall 72, in the form of an elongated cylindrical body, and a top element 73, of circular shape and whose edges are joined to the upper edge of the first side wall 72. The closing element 61a is also similar to the closing elements la and 41a described above, and comprises a second side wall 71 in the form of an elongated cylindrical body and an upper element 75, circular in shape and whose edges are joined to the upper edge of the second side wall 71.

[0165] In the inner region of the top element 73, a cutting device 63 is provided, which comprises a protruding hollow body, which projects downwards, as shown in Figure 31 A, the lower portion of which is provided with a plurality of elements sharp 63a. In Figures 31Ae31B the cutting device 63 does not appear in section, so that it is possible to view it in its entirety.

[0166] The top element 73 is provided in its upper region with a protruding ring 74, which surrounds a through hole 74a. The upper region of the cutter 63 is connected to the lower portion of the top element 73, in the region where the through hole 74a is located, the latter being a continuation of the hollow portion of the cutter 63. Like the cutter 63 , does not appear in section in the Figure, which prevents the through hole from being visualized, the through hole 74a was represented in the Figure by dashed lines, to indicate its location in the top element 73, in alignment with the hollow portion of the device cutting 63.

[0167] A protruding sealing element 76 is provided in the inner portion of the upper element 75 of the closing element 61a. The sealing protrusion element 76 is designed to lodge in the protruding ring 74 and to close the through hole 74a of the base element 61b when the closing element 61a and the base element 61b are closed, as shown in Figures 31A and 31B.

[0168] Preferably the device for automatic opening of the container 61 is designed so that the second side wall 71 of the closing element 61a and the first side wall 72 of the base element 61b have substantially equal outer diameters when closed, as shown in Figure 31 A. In order for this to occur, the top element 73 of the base element 61b must be provided with a recess in the region of its edge where it connects to the first side wall 72, to form an annuliform region 73a. Thus, when the closing element 61a

Petition 870180128395, of 10/09/2018, p. 67/86

36/50 is in the closed position, the lower region of the second side wall 71 will fit into this annuliform region 73a, as can be seen in Figure 31 A.

[0169] This feature is only intended to facilitate the manipulation of the device for automatic opening of container 61 by users, but it is not decisive for the functionality of the device. The configurations of the closing element 61a and the base element 61b can be different from those depicted in the Figures, without, however, changing the functionality of these components for the proper operation of the device for automatic opening of the container 61.

[0170] The device for automatic opening of the container 61 can even be provided without a closing element 61a as shown in the Figure because, according to the principles of the invention, even without this component the device for automatic opening of the container 61 will operate normally, as will be seen below.

[0171] An internal thread 64 is provided in the inner portion of the first side wall 72 of the base element 61b. In the embodiment depicted in the Figures, the internal thread 64 comprises a right-hand orientation thread for simple entry. However, the internal thread 64 can comprise a thread with any number of entries and, consequently, the invention is not limited to the use of an internal thread 64 of simple entry. The orientation of the internal thread 64 may also be on the left.

[0172] The locking device 62 comprises an elongated substantially cylindrical body provided at its upper edge with a plurality of upper rupture elements 62a which are connected to the lower edge of the base element 61b, as can be seen in the Figures. A plurality of lower locking elements 62b is provided in the lower inner portion of the locking device 62.

[0173] The lower locking elements 62b comprise flaps distributed circularly and spaced from each other, the lower portion of each flap being joined to the lower region of the locking device 62 and the body of each flap being inclined towards the geometric axis of the locking device. locking 62. The lower locking elements 62b are designed so that they can undergo small radial bending towards the inner wall of the locking device 62. Other configurations of lower locking elements 62b can be used and therefore the invention is not limited to the configuration depicted in Figures 31A and 31B.

[0174] The upper rupture elements 62a operate in basically the same way as the upper rupture elements 6a and 46a described above, as well as the lower locking elements 62b have basically the same functions performed by

Petition 870180128395, of 10/09/2018, p. 68/86

37/50 previously described lower locking elements 6b and 46b. For this reason, a more detailed description of how these components operate will not be made here.

[0175] Other configurations of rupture elements can be used in the upper rupture elements 62a, as long as they are capable of providing the same effects obtained with the use of the rupture elements depicted in the Figure.

[0176] The device for automatic opening of container 61 should be screwed into a nozzle 65 provided in a container 70. The nozzle 65 comprises an elongated cylindrical body 66 provided in its outer region with an external thread 67. The internal thread 64 of the element base 61b will thread onto the external thread 67 of the nozzle 65, as will be seen below. A retaining ring 68 is provided in the outer region of the elongated cylindrical body 66, below the outer thread 67, and a lower ring 69 is provided in the lower outer region of the elongated cylindrical body 66, as can be seen in the Figures. Similar to the nozzles 12 and 47 described above, the nozzle 65 is provided at its edge with a sealing element 77, shown in Figure 31B.

[0177] In Figures 31Ae31B, the device for automatic opening of the container 61 is in a position immediately before the beginning of its application to the nozzle 65. The application will be made through an initial operation of inserting the lower portion of the device for automatic opening. of container 61 against the upper portion of the nozzle 65, a downward linear motion as indicated by the arrow N in Figure 31B. This operation will cease when the device for automatic opening of the container 61 is properly placed in a position where a rotational movement can be initiated, to cause the internal thread 64 of the base element 61b to screw in the external thread 67 of the nozzle 65. This operation it is performed in a factory installation, using an applicator not shown in Figures 31A and 32B.

[0178] Figure 31C depicts the device for automatic opening of container 61 partially screwed into the nozzle 65, after the rotational screwing movement has started, as indicated by circle B. More particularly, the Figure depicts the moment of the rotational movement for entanglement where the lower locking elements 62b contact the edge of the retaining ring 68. The lower locking elements 62b will then be forced to flex towards the inner region of the locking device 62. According to this rotational movement of screwing is being applied to the device for automatic opening of container 61, it will also undergo a concomitant downward linear movement, as indicated by the arrow N in Figure 31C.

Petition 870180128395, of 10/09/2018, p. 69/86

38/50 [0179] With the continuation of the rotational screwing movement, all the lower locking elements 62b will overtake the edge of the retaining ring 68, as shown in Figure 31D, and will return to their original position, starting to serve as locking means, designed to prevent unscrewing the device for automatic container opening 61.

[0180] The rotational screwing movement will cease when the lower edge of the locking device 62 touches the upper region of the lower ring 69, as shown in Figure 31D. From that moment on, container 70 will be ready to be sent to points of sale.

[0181] A particular feature of this embodiment of the invention is that the screwing of the internal thread 64 of the base element 61b of the device for automatic opening of the container 61 on the external thread 67 of the nozzle 65 is partial, as shown in Figure 31D. This means that, at the end of the rotational screwing movement of the device for automatic opening of container 61 in the nozzle 65, it would still be possible to continue screwing if this movement was not prevented by the touch of the lower edge of the locking device 62 in the upper region of the ring. lower 69, as previously described.

[0182] The use of the lower locking elements 62b is optional, although recommended, since its option is only to prevent inadvertent unscrewing of the device for automatic opening of container 61, as described above. Even without them the device for automatic container opening 61 would operate normally.

[0183] As a result of this partial screwing, the lower ends of the cutting elements 63a of the cutting device 63 will be positioned very close to the sealing element 77 adhered to the edge of the nozzle 65, as shown in Figure 31 D.

[0184] This partial screwing is essential for the user to be able to open the container 70. For this, the user will only need to rotate the device for automatic opening of the container 61 in a clockwise direction, which will cause the rupture of the upper rupture elements 62a, and, consequently, the internal thread 64 of the base element lb of the opening device to screw in. container 61 on the external thread 67 of the nozzle 65 will proceed.

[0185] Concomitantly with this screwing movement there will also be a linear downward movement of the device for automatic opening of the container 61, and the combination of these two movements, clockwise and linear downward, will cause the

Petition 870180128395, of 10/09/2018, p. 70/86

39/50 cutting elements 63a of the cutting device 63 progressively pierce the sealing element 77 adhered to the edge of the nozzle 65.

[0186] These downward rotational and linear movements of the device for automatic opening of container 61 will cease when the edge of the nozzle 65 touches the lower region of the top element 73, and when this occurs the cutting elements of the cutting device 63 will have already performed perforation of the sealing element, and the product stored in the container 70 can then be served, passing through the hollow interior of the cutting device 63 and the through hole of the base element 61b.

[0187] Some aspects are relevant to the design of the device for automatic opening of container 61, so that it can operate correctly to open container 70, as previously described. One of these relevant aspects is to design the lower locking elements 62b in such a way that, after they pass the edge of the locking ring 68, they resist any attempts to unscrew the device for automatic opening of the container 61.

[0188] This is desirable because users are usually used to perform a counterclockwise rotational movement to unscrew a cap from a nozzle, due to the massive use of right-hand threads on caps and nozzles, and there may be situations where that users inadvertently tend to attempt to unscrew the device for automatic opening of container 61 from nozzle 65, without first realizing the need to continue to perform a screwing operation of the device for automatic opening of container 61 in nozzle 65 to perform opening of the container 70, [0189] In these situations it is desirable that the resistance opposed by the lower locking elements 62b to this attempt to unscrew the device for automatic opening of the container 61 of the nozzle 65 is such that it makes it extremely difficult to achieve this unscrewing operation. The user must then pay attention to the instructions for correctly opening the container 70, performing a clockwise rotation operation, to continue screwing. As mentioned earlier, these instructions may appear in the upper region of the upper element 75 of the closing element 61a.

[0190] The dimensioning of some of the components of the device for automatic opening of the container 61 object of this embodiment of the invention, particularly of the base element 61b and the locking device 62, is an aspect of fundamental importance for the device for automatic opening of container 61 operates as previously described to open package 70, as will be seen below.

Petition 870180128395, of 10/09/2018, p. 71/86

40/50 [0191] In Figure 31A it can be seen that the nozzle 65 has a linear extension Li between its edge and the edge of the retaining ring 68, and a linear extension Ci between that edge of the retaining ring 68 and the portion of the upper region of the lower ring 69 where the lower edge of the locking device 62 will touch, at the end of the assembly of the device for automatic opening of container 61 in container 70, as shown in Figure 31 D.

[0192] It can also be seen in Figure 31A that the base element 61b has a linear extension L2 between the lower part of the annuliform region 74a of the element and its lower edge, and a linear extension C2 between that lower edge of the element of base 61b and an imaginary plane formed by the upper region of the lower locking elements 62b.

[0193] In Figure 31D, the linear extension L3 represents the insertion of the linear extension of the nozzle 65 between its edge and the edge of the retaining ring 68 inside the device for automatic opening of the container 61, after the device is in the final position. of its application to the nozzle 65. The linear extension C3 represents the spacing between the edge of the nozzle 65 and the bottom of the annuliform region 73a of the top element 73.

[0194] In order for the device for automatic opening of the container 61 object of this embodiment of the invention to operate in the manner previously described, it is necessary that the linear extensions Li, L2 and L3 described above are substantially identical, allowing small variations resulting from manufacturing tolerances that do not impair the perfect fit of the components related to these linear extensions. Likewise, the linear extensions Ci, C2 and C3 must also be substantially identical, with the same comments regarding manufacturing tolerances. These are geometric relationships that must be considered in the design of the device for automatic container opening 61.

[0195] Figures 32A and 32B are seen in top perspective showing a device for automatic opening of the container 41 whose base element 41b is provided with a ministering device 53. In Figure 32A the closing element 41a is in the open position, and in Figure 32B it is in the closed position, in partial section. The dispensing device 53 comprises an integrally hollow body formed by a first curved portion 53a and a second portion 53b.

[0196] The first curved portion 53a has one end connected to the hollow body of the cutter 43 (not shown in the Figures), and its other end is connected to one end of the second horizontal portion 53b, and the latter extends on the upper face of the base element 41b towards the edge, as shown in

Petition 870180128395, of 10/09/2018, p. 72/86

41/50

Figure 32A. The other end of the second horizontal portion 53b is chamfered and forms an edge 53c, which defines a through hole 53d.

[0197] The closing element 41a is provided with a sealing element 54, which is designed to rest on the edge 53c of the second horizontal portion 53b when the closing element 41a is in the closed position, as can be seen in the view in partial section depicted in Figure 32B. In this way, the sealing element 54 blocks the undesirable passage of product through the through hole 53d if, for example, the container is placed in an inclined position, with closing element 41a in the closed position, or even in an inverted position, supported on the upper face of the closing element 41a.

[0198] In these situations there would be a possibility that the product would run through the through hole 53d and accumulate inside the void formed between the closing element 41a and the base element 41b. In that case, when a user was to manipulate the container and open the closing element 41a, an undesirable product spill would occur. Such a situation is prevented by the sealing element 54, which seals the through hole 53d.

[0199] This configuration of the dispensing device 53 makes it possible for the product stored in the container to be served without the user having to place the container in a position where the through hole is substantially facing downwards, which can cause an overflow of the product, notably products with thixotropic characteristics.

[0200] To serve the product, the user will only need to tilt the container enough to start a flow, which can be easily controlled by varying the angle of inclination of the container, together with the exercise of slight compression in the container, in the event that it is made of flexible material. The dispensing device 53 may be used in conjunction with any of the embodiments and variations of the invention described earlier in this report. Thus, mutatis mutandis, the device for automatic opening of container 1 shown in Figures IA to 12, and 14A to 22 may also be provided with a delivery device 53 as previously described.

[0201] In the previous description of the embodiments of the invention it has always been shown that the device for automatic opening of the container is provided with a closing element and a base element, joined by a tilting connecting element. However, other configurations for these components can be used, in addition to those described in this report. For example, the closing element can be attached to the element

Petition 870180128395, of 10/09/2018, p. 73/86

42/50 base by means of a thread, or by means of a pressure coupling, as previously mentioned.

[0202] Alternatively, there is no impediment for the device for automatic opening of the container of the embodiments described in this report to be provided only with the base element lb, 41b or 61b although in that case the through hole for the administration of the product would be permanently open, without any seals.

[0203] To avoid this problem, some solutions can be used. For example, as shown in Figure 33, in relation to the embodiments depicted in Figures IA to 12C, merely for example, a protruding buffer element 58 formed by an elongated hollow body whose upper portion is closed, and the lower portion is provided, may be provided. open and firmly connected to the top element 10 of the base element 1b, with the hollow portion of the protruding buffer element 58 becoming aligned and in communication with the through hole 2a and, consequently, with the hollow portion of the cutting device 3.

[0204] In this case, after a user has performed the operation of opening the container, he will have to use a cutting element, a knife, for example, to perform a cross section in the body of the protruding buffer element 58 to release the passage of the product stored in the container inside the hollow portion of the protruding buffer element 58.

[0205] A cover 59 can be provided to close this passage in the hollow portion of the protruding buffer element 58, in order to prevent that passage from being permanently open. Preferably the cap 59 is connected to the base element 1b by means of a flexible connecting element 60, to prevent the cap 59 from being inadvertently discarded by the user.

[0206] Of course, mutatis mutandis, this solution could also be used in the embodiments depicted in Figures 23 A through 31B. Note that the lid 59 and the closing element la, or the closing element 41a, perform the same function of sealing the passage of the product stored in the container through the through holes 2a or 39a, respectively. The only difference is that the lid 59 is dimensioned to accommodate around the body of the protruding buffer element 58, which results in a smaller component, thereby saving material.

[0207] Figures 34A and 34B depict perspective views showing a rotational locking system that can be used in conjunction with any of the devices for automatic container opening described previously. Just to exemplify the

Petition 870180128395, of 10/09/2018, p. 74/86

43/50 said rotational locking system will follow a description in which the embodiment of the device for automatic opening of the container 41 shown in Figures 23A, 23B, 23C and 24 was chosen. Thus, mutatis mutandis, this rotational locking system may also be used in the devices for automatic opening of container 1 and 61 described above.

[0208] It can be seen in Figures 34A and 34B an external thread 45 being screwed in the internal thread 44. Each of the external thread 45 is provided with a rotational locking recess 45b, which is designed to fit in a rotational locking shoulder 44 and provided in one of the threads of the thread 44.

[0209] The location of each rotational locking recess 45b and each rotational locking shoulder 44e must be determined in such a way that the fit between them occurs at the same time as the inner portion of the top member 55 of the base element 41b run over the edge of the nozzle 47. Thus, when a consumer performs the operation of opening the container, by means of a clockwise rotation of the set formed by the closing element 41a and the base element 41b, at the moment when the recesses of rotational locking 45b fits the rotational locking lugs 44e and the thread 44 the consumer will hear a click, and from that moment on he will no longer be able to perform the rotation of the set, in any direction, as the whole set will be locked in this position.

[0210] The rotational locking system pictured in Figures 34A and 34B prevents the assembly formed by the closing element 41a and the base element 41b from rotating to unscrew the thread 44 in a counterclockwise direction. It therefore serves as a measure to hinder the removal of that assembly formed by the closing element 41a and the base element 41b, and prevents the container from being refilled after the originally stored content has been used up.

[0211] As seen in the descriptions of the different embodiments and variations of the devices for automatic opening of the container object of the invention, the fundamental characteristic of all of them is the provision of a cutting device that, in addition to serving as a lid for the container, is provided with a means to perform a cutting operation of the sealing elements usually provided on the edges of the nozzles of the containers, thereby creating a passage so that the product contained in the container can be served. This eliminates the need to perform the operations of unscrewing and removing the lid, manually removing the sealing element and screwing the lid back on the container, as is currently the case. As it turned out, this invention makes it unnecessary for consumers to even have to withdraw

Petition 870180128395, of 10/09/2018, p. 75/86

44/50 the lid of the containers to remove the sealing elements that are applied to the edges of the nozzles.

[0212] With the use of the embodiments of the device for automatic opening of the container of the invention, the sealing element may have its thickness calculated to simply seal the container. Therefore, there will no longer be a need to use thicker sealing elements solely to prevent consumers from inadvertently damaging or puncturing them at points of sale when they are checking that the container is properly sealed, or to facilitate the manual operation of its removal , aiming that they do not suffer tears in this operation.

[0213] The use of a multiple entry thread in the embodiments of the device for automatic opening of containers previously described provides a much greater advance than would be obtained with a single entry thread, and allows the operation of opening the containers to be made very quickly. The faster the container opening operation, the easier and faster the cutting of the sealing element by the cutting elements of the cutting device, taking advantage of the fact that the sealing element is still well tensioned, due to its strong connection to the edge of the nozzle.

[0214] The shape characteristics of the cutting elements in the cutting device must be determined according to the cutting speed provided by the type of thread used in the device for automatic opening of the container and the characteristics of the material used in the sealing element.

[0215] Anti-vandalism devices may be used in conjunction with the various embodiments and variations of the invention described in this report, in order to guarantee the user that the container has not been violated. For example, wrappers around the devices and the nozzle can be used, which are provided with tear lines that facilitate their removal, as is well known in the art.

[0216] If a container is provided with a device for automatic opening of the container according to the invention in which there is no connecting element to hold the closing element la or 41a, or the lid 59, connected to the base element lb , or 41b, it is recommended that an anti-vandalism device is used to cover the device for automatic opening of the container, thereby preventing the closing elements la, 41a, 61a or the lid 59 from being unduly removed when the container is on storage shelves. outlets.

[0217] The present invention has been described in relation to its various embodiments and variations. Modifications or substitutions may be made to the invention without, however,

Petition 870180128395, of 10/09/2018, p. 76/86

45/50 however, change the inventive concept described and revealed in this report. Consequently, the invention is not limited only to the embodiments and variations described herein, it is limited only to the claims accompanying this report.
