Definitions

  • the present invention relates to a two-component container in accordance with the preamble of claim l.
  • Two-component containers are used, for instance, for handling two-component cements, which release noxious gases, by making the reaction between the components take place in a gas-tight space, separated from the environment, by means of a piercing mechanism.
  • the components form the desired cementing composition, which can be applied to a desired object.
  • a prior-art invention described in FI patent publication 57 378 comprises two concentric containers and a cover with the inner container holding a piercing mechanism, whose construction consists of a separate piercing member fabricated in one piece and with its maximum dimension in the orthogonal direction to the axis of the container being at least of the same order of magnitude with the diameter of the inner container.
  • a drawback of prior-art technology is that due to the construc­tion of the piercing member used, the hole pierced at the compartmental wall of the inner container in practice is formed at the circumferential area, which makes the mixing of components inefficient. Due to the method of piercing the hole at the circumferential area, the piercing mechanism is so unreliable as to require in practice the cover to be adapted removable, which deteriorates the system's hermeticity.
  • the aim of the invention is to overcome the drawbacks of the aforementioned prior-art technology and to provide a novel piercing mechanism for a two-component container.
  • the invention is based on providing a piercing member whose maximum dimension in the plane orthogonal to the inner container axis extends to approximately half way of the container diameter, and which is complemented with a support member, which makes the combined maximum extension of the support member and the piercing member in the plane orthogonal to the container axis to be approximately of the magnitude of the container diameter.
  • the invention offers substantial benefits.
  • the piercing mechanism in accordance with the invention pierces the hole in the center of the inner container compart­mental wall, which makes the mixing effective.
  • the support member By means of the support member, the piercing member is centered and the reliability of the piercing mechanism increases so much as to allow the cover to be permanently attached to the can, which improves the hermeticity of the container and simultaneously increases the allowable storage time of the material.
  • Figure l shows a possible solution for fabricating a blank l for the piercing member of a piercing mechanism.
  • the blank l can be divided into an upper part 6, a blade part 2, and blade support flaps 3.
  • the support flaps 3 are bent outwards from the plane of the blank l, after which the blank l is bent in accordance with Figure 2 into a V-shape by using a punch 5 and an anvil 4.
  • an oblong support member 7, fabricated of thin sheet metal is attached to the other side of the bent blank.
  • a can 8 forms compartment II and the part of the container remaining below it forms compartment I.
  • the piercing member l3 with its support member is inserted in the inner can 8 of the two-component container so that the support member 7 is essentially perpendicular to the longitudinal axes of cans l0 and 8. Then, the blade part 2 rests against a downward convex wall of the inner can 8, fabricated of a thin material, e.g. aluminum, and the upper part 6 is either resting against the upwards concave cover 9 or located to its immediate vicinity.
  • the largest dimension of the piercing member blank l is approximately of the same magnitude with the inner can 8 diameter, which makes the largest dimension of the bent blank l to be in the order of magnitude with the can radius. Due to the chosen blank length, the blade part 2 becomes located essentially to the center of the can 8.
  • the support member 7 inhibits the sideways movement of the piercing member l3, the piercing of the inner can 8 bottom takes place extremely reliably when the blade part is pressed through the center of the can cover 9. Then, the upper part 6 of the piercing member l3 under the cover 9 mediates the piercing force and the blade part 2 punches a hole in the center of the inner can 8 bottom to allow the contents of the inner can 8 to flow into the lower can l0 for effective mixing.
  • a seam ll of the container can be fabricated so that the cover 9 of the container is non-detachable.
  • the fabrication is accomplished in accordance with Figures 5...7 by applying in accordance with Figure 5 to the inner surface of the cover part 9, an adhesive-like sealing material l2 and providing an essential­ly larger folding margin at the cover part 9, compared with the margin of can parts 8 and l0.
  • the edge of the cover part 9 is roll-bent over the prefolded edges of can parts 8 and l0 in accordance with Figure 6; and also using a prior-art method, the seam is completed in accordance with Figure 7.
  • the sealing material l2 provides hermeticity for the entire container assembly.
