Abstract

PURPOSE: To make appropriate a squeezing strength at a shoulder part and prevent deterioration of contents by a method wherein a shoulder of a laminated tube is formed by a resin in which a specified amount of ethylene/vinyl alocohol copolymer resin is mixed to either olefinic thermoplastic elastomer or olefin thermoplastic elastomer. CONSTITUTION: In the case that a shoulder part is formed with single element of olefinic thermoplastic elastomer, it is possible to maintain a squeezing strength of at most 2kg with a wall thickness of 1.4 to 1.5mm (a wall thickness same as in the present process) at the shoulder. In addition, in the case that the wall thickness of the shoulder is formed to be thinner than that of the current product, it is probable that either a reduction of gas barrier or a reduction in adhesion strength at the barrel part may be caused. Accordingly, in order to prevent a reduction of gas barrier, EVOH is mixed in a range of about 20 to 35wt.% to enable its value to be less than that of the current value. A squeezing strength of content can be maintained at a squeezing strength of lower than 2kg due to the thinner formation of the wall thickness of the shoulder than that of the current product. As to the wall thickness of the shoulder in this case, it is preferable to keep its value at most 1.0mm.

2. Description of the Related Art In a conventional laminated tube, the resin of the shoulder portion is molded with high density polyethylene. When the contents are squeezed out to the end, the shoulder portion is very hard and there is a feeling of resistance, and it cannot be squeezed. However, it is often seen that the contents remain, and this tendency increases as the tube diameter increases. Therefore, in order to weaken the pushing pressure strength of the shoulder portion when pushing out the contents, methods such as thinning the thickness of the shoulder portion and molding with a soft and weak bending strength resin have been considered.

Generally, a laminate tube containing a toothpaste or the like has a body formed of a laminate film using a barrier material having an oxygen barrier property or a water vapor barrier property, and a high density polyethylene injection tube. The shoulder portion is formed by a molding method or the like. The barrier material forming the body portion refers to, for example, a plastic film or an aluminum foil on which an inorganic substance is deposited, and the body portion is formed by using these as a constituent element. The method of fusion-bonding the body and the shoulder is generally performed by an insert molding method in which the shoulder is formed and heat-bonded to the body at the same time.

Further, the thickness of the shoulder portion is usually about 1.5 mm, and a force of about 4 kg is required to deform the shoulder portion having this thickness and squeeze the contents to the end. on the other hand,
The force required for deformation is about 2 to squeeze the contents to the end.
If it is about kg, it can be normally used. As described above, it is difficult to squeeze out the contents by deforming the shoulder portion of an ordinary laminate tube. In order to squeeze out with a force of about 2 kg, it is possible to squeeze out by reducing the thickness of the shoulder to about 1/2 of the normal thickness, but this is not practical because the adhesive strength between the body and the shoulder is insufficient. Furthermore, the gas barrier property and the water vapor barrier property are reduced as the thickness is reduced, and the possibility of content deterioration is increased.
