Definitions

  • the invention relates to a tube and to a method for producing such a tube according to the preamble of the independent claims .
  • Tubes of this kind are used for holding and dispensing pastes, liquids or other products, in particular pharmaceutical, dental or cosmetic products.
  • Tubes are used as a way of packaging, in particular for liquids and pastes .
  • they comprise a tubular flexible body, a shoulder and a neck with an outlet.
  • ⁇ shoulder is used to designate the portion of the tube which connects the body with the neck and should not be regarded as a part of the body.
  • the shoulder can be seen as a portion of the tube which acts as an adapter between the larger diameter of the body and the smaller diameter of the neck.
  • the tube body is normally, at least on the side of the outlet, substantially cylindrical.
  • the end of the body opposite to the outlet is usually initially left open, such that the contents can be filled into the tube. After the filling, the end of the body opposite to the outlet is sealed such that it is flat.
  • the shoulder is usually substantially conical or it has the shape of a ring.
  • the body is flexible, such that it can be pressed for dispensing.
  • Known tubes have the disadvantage that emptying them completely is often difficult or even impossible. This is dissatisfactory for the user, uneconomical and environmentally questionable, since always part of the contents remain in the tube and are disposed with it.
  • the tube according to the invention is manifested by the feature that the shoulder is flexible.
  • the shoulder is made substantially from a flexible material having a hardness of not more than 96 Shore A, and in particular not more than 80 or 65 Shore A.

  • the tube 1 comprises a body 2, a shoulder 4 and a neck 5.
  • the tube 1 is substantially made of two components 9, 10.
  • the first component 9 forms the body 2.
  • the second component 10 forms the shoulder 4 and the neck 5.
  • the two components 9, 10 are connected to each other at a rim 3 of the tube 1, in particular by an overlap 8.
  • the neck 5 comprises a thread 7 and an outlet 6.
  • the upper portion of the body 2 is substantially cylindrical. The lower end of the body 2 is not shown .
  • the first component 9 is preferably a laminate structure, in particular a Neopac Polyfoil® laminate. It has preferably a thickness in the range of 0.2 to 0.8 mm, in particular about 0.5 mm.
  • the second component 10 is designed flexible, preferably such that it is easily deformable by hand, i.e. without using a tool.
  • the second component 10 and therewith the shoulder 4 is made sufficiently flexible that a diameter of the shoulder 2 measured in a particular direction can be reduced by at least fifty percent, and in particular by sixty percent, by applying a compressing force by hand.
  • the shoulder 4 is preferably made sufficiently flexible that opposing sides of the shoulder 4 can be squeezed by hand such that the inner surfaces of said opposing sides contact each other.
  • the second component 10 and therewith the shoulder 4 are designed, in particular regarding their flexibility, such that at least 90 percent, preferably 95 percent and in particular at least 98 percent of the contents of a completely filled tube 1 can be pressed out by hand.
  • a typical force which can be applied "by hand” is 5 or 10 Newton.
  • the term "by hand” in this document should be interpreted such that not more than 25 Newton have to be exerted as a compressing force.
  • the second component 10 and therewith the shoulder 4 is made from a flexible material, in particular a TPE (thermoplastic elastomere) .
  • the material has preferably a hardness in the range from 50 Shore A to 96 Shore A. In particular the hardness is not more than 80 Shore A or not more than 65 Shore A.
  • the flexibility of the shoulder 4 can be implemented either by using a softer material or by making the shoulder 4 thinner than in conventional designs, or by a combination of both.
  • the shoulder 4 has a thickness in the range of 0.5 to 1 mm, in particular about 0.75 mm.
  • the second component 10 can be made from a transparent material and/or can be at least partially transparent such that the completeness of the emptying can be observed by the user.
  • a flexible shoulder 4 and, as the case may be, a flexible neck 5 and/or a flexible upper portion of the body 2 has the advantage that the tube 1 can be easily squeezed in the range of the shoulder 4, such that all contents can be pressed out, in particular by completely flattening the tube 1 in the range of the shoulder 4 at least temporarily.
  • Fig. 2 shows a partial sectional view of a further embodiment of the tube 1 according to the invention.
  • the tube 1 is made from a first component 9, which is preferably a laminate structure and a second component 10 which is substantially made from a flexible material.
  • the second component 10 forms not only the neck 5 and the shoulder 4, but also the upper portion of the body 2.
  • the first component 9 forms the lower portion of the body 2.
  • the thickness of the second component 10 in the range of upper portion the body 2, which had not to be defined above is preferably in the range of 0.5 to 1.5 mm and is in particular about 1 mm.
  • the embodiment of figure 2 has, compared to the embodiment of figure 1, the advantage that emptying the upper part of the tube 1 is even easier, because the upper part of the tube 1, which is usually the part which is most difficult to empty, is made completely from the flexible material. Further the overlap 8, by which the two components 9, 10 are connected and which might be less flexible, is not in said upper part of the tube 1 and does therefore not interfere with its emptying. In addition to that, this design is more stable since the overlap 8 is not in the region of the rim 3, which can be exposed to especially high forces or tensions when the tube 1 is squeezed.
  • the upper portion of the body 2 which is formed by the second component 10 has preferably a length in the range of 5 to 30 mm, in particular 20 to 30 mm, or about the same length as the shoulder, measured from the neck 5 to the rim 3, wherein "about” means +/- 5 mm.
  • Fig. 3 shows a partial sectional view of a further embodiment of the tube 1 according to the invention.
  • the shoulder 4 but also the upper portion of the body 2 is made flexible.
  • there is a third component 11 which forms the outer and topmost portion of neck 5.
  • the third component 11 is made harder than the second component 10.
  • the third component 11 is in particular made from PE-HD (Polyethylen High Density) and/or can for example be made by injection molding, in particular a two component injection molding process.
  • Fig. 4 shows a partial sectional view of a further embodiment of the tube according to the invention.
  • the tube 1 comprises a cannula 6 which allows to dispense the contents of the tube 1 spatially more precisely which might for example be desirable in the case of eye drops .
  • a first component 9 which forms the lower portion of the body 2
  • a second component 10 which forms the upper portion of the body 2, the shoulder 4, the inner portion of neck 5 and, in contrast to the embodiment of figure 3, also the cannula 6 and a third component 12 which forms the outer portion of the neck 5 with thread 7.
  • the cannula 6 is from the same material as the shoulder 4 and therefore flexible.
  • a soft cannula can be an advantage, since it can reduce the risk of injuries during dispensing.
  • the flexible shoulder and the flexible cannula being formed by the same component is an advantage regarding the production cost.
  • first the components 9, 10 and, as the case may be, 11 or 12 are produced. Then the components are attached to each other. However, the first component 9 can also be directly injection molded onto the second component 10.
  • a flexible component may have the properties that it can be bent, that it can be expanded and/or compressed and in particular that it is elastic, such that it restores substantially its original shape after the deforming force is released.
  • the shoulder of the tube according to the invention has all these properties.
  • the material of the shoulder is solely easily deformable .
  • thinner aluminum is for example such a material. It is substantially not self restoring, but nevertheless easily deformable.
