Definitions

  • the present invention relates to an automatic opening device for containers that has a spout provided with a sealing element firmly attached to its rim, said automatic opening device for containers being provided with means that eliminates the need to remove the cap of the container and performs multiple operations to remove the sealing element from the edge of the spout to release the ministering of the stored product.
  • sealing elements in containers designed to store products such as condiments for food, soups, liquid or paste products, medicines, cosmetics and other products.
  • the sealing element is firmly attached to the rim of the opening through which the product can be removed from the container, for example at the rim of a pouring spout.
  • a closing element is provided in the pouring spout, usually a cap, which is often provided with an internal screw thread which engages to an external screw thread provided in the pouring spout.
  • the cap will only operate to seal the container after a user removes the sealing element from the rim of the spout.
  • sealing elements are known to adhere to the rim of the spouts of these containers, the characteristics of which vary according to the type of product contained in the container.
  • the sealing elements comprise a multilayer material, which can comprise plastic materials, paper, aluminum films, etc.
  • Patents US6277478 , US6461714 , US7648764 and US8080118 disclose some types of sealing elements.
  • sealing elements applied to the rim of the spout, for example, the need to provide barriers against light, odors, scents, humidity, oxygen, etc., which can jeopardise the quality and the integrity of the product stored in the container.
  • the sealing elements can usually be made in layers of different materials, each of them meeting specific needs.
  • the sealing elements can also serve to extend the shelf life of the products stored in the containers, since the sale to the final user can take place long after the date of manufacture, in some cases in periods longer than one year after manufacture.
  • the sealing elements also serve as an indication to the user that the contents of the container have not been tampered with. If the sealing element shows any sign of tampering when opening the cap, it will signal to the user that the container has been tampered with and the product may have suffered some type of contamination and therefore should not be used.
  • containers caps with spouts with sealing elements in the rim are often not provided with tamper evidence devices, since the sealing element itself serves this purpose. In this case, when purchasing the product, users have just to remove the caps from the containers to check if the sealing element is intact.
  • sealing elements In such situations, users may inadvertently damage the sealing element, which would make the product contained in the container unsuitable for sale.
  • the sealing elements it is common for the sealing elements to be manufactured with layers of thicker materials than would be necessary to serve as a barrier element, aiming to increase its resistance.
  • this option usually creates difficulties for users, causing them difficulties to remove the sealing element when it is necessary to open the container for the first time to pour product contained therein.
  • the cap is provided with a pouring spout that makes it possible to pour the product without the need to disengage the cap from the spout. In these cases, after removing the sealing element, the cap must be re-engaged to the spout, to close the container and allow the product to be served normally through the pouring spout.
  • the sealing elements are provided with at least one side lug that extends downwards the rim of the spout, facing the outer portion of the spout.
  • This side lug aims to facilitate the task of removing the sealing element, and for this aim the user must handle the side lug and make an upward movement.
  • the task of removing the sealing element is still difficult, and frequently users are unable to release the sealing element because it is firmly adhered to the rim of the spout.
  • This operation is not always easy to be performed, being even very difficult for users to handle the remaining parts of the sealing element still adhered to the rim of the spout, in order to remove them.
  • Users often use a sharp instrument, such as the tip of a knife or scissors, to assist removal of said remaining parts of the sealing element, which can cause accidents as well as creating the possibility of product contamination.
  • sealing element it is not uncommon that users instead of trying to remove the sealing element as a whole, choose to simply cut it, usually with a sharp instrument, such as the tip of a knife or scissors.
  • a sharp instrument such as the tip of a knife or scissors.
  • one of the layers of the sealing element comprises a resilient plastic material, usually this may cause some resistance for users to be able to puncture the sealing element.
  • the difficulty to release the sealing element may be even greater if it is quite thick, notably in containers in that the cap is not provided with a tamper evidence element, wherein the sealing element also serves to hinder tampering with the container, as previously mentioned.
  • the need to provide a sealing element at the rim of the container spout, for the preservation of the product usually causes difficulties for users. Besides being necessary the users perform a sequence of operations to open the container (unscrew the cap of the spout, remove the sealing element from the rim of the spout and then screw the cap back on the spout), the operation of releasing the sealing element from the rim of the spout can even cause accidents.
  • caps for container which also serve as sealing element for the containers.
  • These caps are usually provided with a protruding element at the top, usually in the form of a cone trunk, which will later be used for pouring the product stored in the container.
  • Said protruding element has its upper end closed, and therefore it will be necessary for users to use a cutting instrument, a knife, for example, to cut the upper portion of the protruding element, thereby opening a pouring orifice for the product into the container. It is then highly possible that accidents occur during this operation, especially if performed by children or older people.
  • caps can be provided in one piece or in two pieces joined by a pivoting element, one of the pieces being the part that is applied to the spout and the other serves as a closing element.
  • the present invention provides an automatic opening device for containers provided with sealing elements fixed to the rim of the pouring spout, thereby allowing the operation for tearing the sealing element to be made in a single operation, whereby eliminating the need for the userto perform multiple tasks in order to tear the sealing element to open the containers.
  • the present invention allows the sealing elements to be manufactured without the need to be thicker than necessary, thereby serving only as a barrier element. Consequently, it eliminates the need for the sealing elements to be more resistant to avoid accidental ruptures, as currently observed.

However, the automatic opening device for containers 61 would operate normally if it were not provided with the lower locking elements 62b.
  • This partial screwing is fundamental to facilitate the opening of the container 70 by a user, who will only need to rotate the automatic opening device for containers 61 in a clockwise direction, thereby causing the tearing of the upper rupture elements 62a. Consequently, the screwing of the internal screw thread 64 of the base element 1b of the automatic opening device for containers 61 on the external screw thread 67 of the spout 65 will go on.
  • Some aspects are relevant for designing the automatic opening device for containers 61, to enable it to operate correctly to open container 70.

Consequently, the sealing element 54 blocks the undesirable passage of product through the throughout orifice 53d if, for example, the container is placed in an inclined position with the closing element 41a in the closed position, or even in an inverted position, supported on the upper face of the closing element 41a .
  • the sealing element 54 prevents the possibility for the product to flow through the throughout orifice 53d and accumulate inside the empty space formed between the closing element 41a and the base element 41b . In case the sealing element 54 were not provided, when a user would open the closing element 41a , an undesirable product spill would occur.
  • This embodiment of the pouring device 53 enables a user to pour the product stored in the container without having to place the container upside-down, in a position where the throughout orifice is substantially downwards, which can cause the product to overflow, in special thixotropic products.

Therefore, when a user opens the container, by means of a clockwise rotation of the assembly formed by the closing element 41a and the base element 41b , at the moment when the rotational locking recesses 45b latches into the locking shoulder 44 of the screw thread 44, the user will hear a snap.
