Abstract

PURPOSE:To form the tube vessel, having no faulty sealing and very high in sealing property, by a method wherein protruded and recessed section is provided on either one of the connecting surfaces of the tube vessel used for accommodating food, such as mustard, 'wasabi' or the like, industrial medicines or the like to effect high-frequency seal. CONSTITUTION:A bottle neck 1, consisting of an opening 2, provided with screw thread, and a shoulder, consisting of conical wall, which are molded integrally, is formed by injection molding. In this case, protruded and recessed part 4 is molded simultaneously on the tip end outer surface of the shoulder 3. The recessed and protruded section 4 is fitted into one end of a cylindrical section 5, formed cylindrically previously. Subsequently, the inner surface of the cylindrical section 5 is pressed against the recessed and protruded section 4 and high-frequency wave is projected against the pressed section to melt resin of the recessed and protruded section 4 and weld the cylindrical section 5 to the shoulder 3 by fusion welding. In this case, the molten resin of protruded section is spread into the circumference of the recessed and protruded section 4 of the shoulder 3 and the shoulder 3 is welded to the cylindrical section 5 by fusion welding without remaining any clearance. According to this method, the cylindrical section is welded to the bottle neck without remaining any clearance and the tube vessel, very high in sealing property, may be obtained.

る。(Prior art) Conventionally, methods for manufacturing tube containers include manufacturing the body and mouth shoulder separately in advance and then joining the body and mouth shoulder, or placing the body in an injection mold. After inserting the part, there is a method of pouring molten resin into the mold to form a mouth shoulder part of a desired shape. In the former method, high-frequency treatment is performed by taking advantage of the fact that the body has a multilayer structure with a metal foil such as aluminum as an intermediate layer, or that the mouth shoulder has an insert such as aluminum foil. High-frequency sealing, which heat-welds the body and mouth shoulder, is usually performed.

Therefore, if the joint surfaces are not in complete contact during sealing, sealing failure will occur.
There was a problem that the container could not be kept tightly sealed.

を考慮して、最内層７にはポリエチレンを使用した。First, a mouth shoulder part l is manufactured by injection molding, in which a mouth part 2 provided with a threaded part and a shoulder part 3 made of a conical wall part are integrally molded. At this time, the outer surface of the tip of the shoulder portion 3 has a third
A concavo-convex portion 4 having grooves A in the circumferential direction as shown in the figure is formed at the same time. As the resin for the mouth shoulder part 3, polyethylene was used in consideration of its weldability with the body part 5. The uneven portion 4 is not limited to that shown in FIG. 3, but may be formed of a large number of protrusions B as shown in FIG. ) etc. may be used. Next, as shown in FIG. It is a cylindrical body with a multilayer structure, and polyethylene was used for the innermost layer 7 in consideration of weldability with the mouth shoulder part 3.

At this time, the melted resin of the convex part in the uneven part 4 of the shoulder part 3 spreads around and flows into the gap between the shoulder part 3 and the innermost layer 7. Therefore, the shoulder portion 3 is welded to the body portion 5 without any gaps.

器を得ることができる。In addition, in the above embodiment, polyethylene alone was used for the mouth shoulder, but if particularly sealing performance is required, an opening may be formed inside the resin layer 1) of the mouth shoulder 10 as shown in FIG. A gas-tight insert 12 may be provided to close off. The insert 12 is an integrally molded piece of metal foil such as aluminum whose both sides are coated with heat-fusible synthetic resin. 1I12 is placed on a mold core for injection molding, and a molten resin is poured into the mold core to obtain a mouth shoulder portion IO having a desired shape. The above-mentioned uneven portion 4 is provided on the mouth shoulder portion 10.
By welding the shoulder portion 10 and the body portion 5 using high frequency, a highly hermetic tube container can be obtained.

In addition, there are some that have a resin layer provided on the outside. The body portion made of only the synthetic resin layer and the mouth shoulder portion 10 are joined together by the metallic insert 12 generating heat through high-frequency irradiation and melting the surrounding resin.
