Method for manufacturing a capsule made of aluminum for small tubes with open hole and product so obtained
Capsule made of aluminum, suited to seal small tubes with open hole by using a capsule made of the same metallic material as the tube, the capsule being useful in the recycling of its materials after their end use; the capsule including: a cylindrical body made of aluminum, derived from the pressure received from the punch during cavity formation; a thread, imparted within the wall of the capsule, in turn imparting a thread on the outlet of the present small tube with open hole; at least a seal, installed on the internal side of the upper face of the capsule, isolating the product contained within the small tube and to increase the sealing properties of the package; and at least a lower band, adapted to represent a security seal so as to distinguish the capsules that have already been unscrewed from those that are still new.
1 . A method for manufacturing a capsule made of aluminum, for a small tube with an open hole, the capsule and small tube forming an aluminum package, the capsule adapted to seal the small tube by using the same aluminum construction material employed in making the small tube, so that the small tube is a small aluminum tube and so as to render all of the aluminum package eco-sustainable, the method comprising:
studying physical properties of treated aluminum, using analysis of elasticity and heat and deformation resistance;
extending an aluminum sheet, engaged within a die to maintain said aluminum sheet in position during pressing;
deforming the aluminum sheet using a punch, to impart a cavity, creating said aluminum capsule with a cylindrical body, the cylindrical body derived from pressure received from the punch during formation of the cavity;
carrying out quality control randomly on one of the manufactured capsules;
inserting a food membrane seal, which is adherent with an upper internal part of the capsule and constitutes less than 0.4% of the entire aluminum package, to isolate the packaged product within the small tube from outside environment; said food membrane seal being adapted to be recycled together with all of the small tube since the food membrane seal constitutes less than 0.4% of the entire aluminum package; and
mounting a visible lower band inferiorly on said capsule in order to distinguish a new capsule from an already open capsule, the lower band being visible so as to realize a warranty seal to identify the capsule as being new and, upon unscrewing the small tube from the capsule, to identify the capsule as having been already opened, so as to identify whether the small tube is still new and whether the small tube has previously been opened.
2 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 1 , wherein said punch is adapted to impart a round and flat shape to an upper face of the capsule.
3 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 1 , wherein said capsule is attained by pressure of a punch, adapted to make a capsule with conical shape, improving the sealing capacity thereof.
4 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 1 , wherein during the step of deformation of the aluminum sheet, a thread is imparted within the capsule, for the purpose of subsequently imparting the thread to an outlet of the small tube by impression, when said capsule is screwed for sealing the aluminum package the first time.
5 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 1 , wherein said seal is made of food silicone material.
6 . A capsule made of aluminum for small tubes with open hole, said capsule being manufactured using the manufacturing method of claim 4 , in order to seal the small tubes with the open hole, said capsule comprising:
the cylindrical body made of aluminum, derived the pressure received from the punch during cavity formation;
the thread, imparted within the wall of said capsule, in turn adapted to impart the thread on the outlet of the present small tube with the open hole;
the food membrane seal, installed on the internal side of the upper face of the capsule, adapted to isolate the product contained within the small tube and to increase the sealing properties of the package; and
the visible lower band, adapted to represent the warranty seal so as to distinguish the capsules that have already been unscrewed from those that are still new.
7 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 2 , wherein said capsule is attained by pressure of a punch, adapted to make a capsule with conical shape, improving the sealing capacity thereof.
8 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 2 , wherein during the step of deformation of the aluminum sheet, a thread is imparted within the capsule, for the purpose of subsequently imparting the thread to an outlet of the small tube by impression, when said capsule is screwed for sealing the aluminum package the first time.
9 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 3 , wherein during the step of deformation of the aluminum sheet, a thread is imparted within the capsule, for the purpose of subsequently imparting the thread to an outlet of the small tube by impression, when said capsule is screwed for sealing the aluminum package the first time.
10 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 7 , wherein during the step of deformation of the aluminum sheet, a thread is imparted within the capsule, for the purpose of subsequently imparting the thread to an outlet of the small tube by impression, when said capsule is screwed for sealing the aluminum package the first time.
11 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 2 , wherein said seal is made of food silicone material.
12 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 3 , wherein said seal is made of food silicone material.
13 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 4 , wherein said seal is made of food silicone material.
14 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 7 , wherein said seal is made of food silicone material.
15 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 8 , wherein said seal is made of food silicone material.
16 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 9 , wherein said seal is made of food silicone material.
17 . The method for manufacturing the capsule made of aluminum for the small tube with the open hole, according to claim 10 , wherein said seal is made of food silicone material.
