JP2000159247A - Printing position alignment mark in plastic vessel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enhance the value of goods by elongating the stopper of one cap positioning member, and allowing its elongated end part to be a printing position alignment mark that also serves as a stopper in the one having a pair of cap positioning member disposed as the printing position alignment mark of a vessel. SOLUTION: This tube vessel A has a mouth part 1, a shoulder part 2, and trunk part 3, and a lower end of the trunk part is sealed as being filled with a content. The mouth part 1 comprises an extrusion sleeve 4 and screwed sleeve 5, and the shoulder part 2 comprises a shoulder wall step-configured part 9 and a shoulder wall 10, and further, a pair of cap positioning members 13a, 13b comprising stoppers 11a, 11b and joint strips 12a, 12b are arranged at symmetrical position in a manner crossing an axis of the vessel. The stopper 11a of one cap positioning member 13a is elongated outward, and the elongated part thereof is allowed to be used as a printing alignment mark 14. This can avoid a sense of incongruity in a design, and also can enhance the value of goods.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alignment mark for printing on a plastic container, particularly a tube container.

[0002]

2. Description of the Related Art In printing on the surface of a tube container, it is well known that a container is provided with an alignment mark for printing in order to print it at a desired fixed position. It has been proposed to dispose a pair of cap positioning members on the shoulder wall step at the lower end of the mouth, and to project a positioning projection on the shoulder wall in proximity to the shoulder wall step.

[0003]

However, the positioning projections provided on the shoulder wall remain as useless projections after printing, and there is a problem in that when the container is used, the design of the container gives a sense of incongruity. Further, depending on the projecting position, the lower end of the positioning stopper rod provided on the screwed cylinder of the cap may be engaged to hinder the cap positioning.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a printing positioning mark for a container in which a printing positioning mark is also used as a stopper of a cap positioning member provided on a shoulder wall of the container. The purpose is to provide the mark.

[0005]

According to the present invention, a pair of cap positioning members are provided at a shoulder wall step at a lower end of a container mouth as a printing alignment mark of the container in order to achieve the above technical object. In the plastic container described above, the stopper of one of the cap positioning members is extended, the extended end is used as a printing alignment mark, and the stopper is also used as the stopper of the cap positioning member.

[0006]

Next, embodiments of the present invention will be described with reference to the drawings. The container of the present invention comprises a tube container A and a cap B, both of which are molded from a synthetic resin. As shown in FIGS. 1 and 2, the tube container A has a mouth 1, a shoulder 2, and a body 3, and the lower end of the body 3 is sealed when filling the contents.

[0007] The mouth 1 comprises an extrusion tube 4 and a screw-in tube 5, and an extrusion opening 6 is formed in the top wall of the extrusion tube 4 to form a body 3.
When is pressed, the contents are extruded. A screw 7 is engraved on the peripheral surface of the screwing cylinder 5, and a lower end portion is an enlarged diameter peripheral surface 8.

The shoulder portion 2 comprises a circular shoulder wall step 9 extending outward from the enlarged diameter peripheral surface 8 at the lower end of the mouth 1, and a shoulder wall 10 continuous with the shoulder wall step 9. A stopper 11 a provided on the shoulder wall step 9 so as to protrude from the enlarged diameter peripheral surface 8,
A pair of cap positioning members 13a and 13b composed of b and engagement pieces 12a and 12b are disposed at symmetrical positions with respect to the container axis. The stopper 11a of one of the cap positioning members 13a is extended outwardly, and the extended portion is used as a positioning mark 14 for printing.

As shown in FIGS. 3 and 4, the cap B has a top wall 20, a side wall 21, and a screwing cylinder 22 disposed inside the side wall 21. On the inner circumference of the screwing cylinder 22, a screw 23 screwed to the screw 7 on the outer circumference of the mouth 1 is engraved. On the outer circumference, two stopper rods 24a, which engage with the cap positioning members 13a, 13b, are provided. The stopper rod 24 and the side wall 21 are connected by a support plate 25. At the center of the inner surface of the top wall 20, a plug 26 for closing the extrusion port 6 is provided.

Next, the operation and effect of the container of the present invention based on the above configuration will be described. The body 3 at the time of molding the tube container A is a cylinder whose lower part is open, and the surface of the cylinder is printed after molding. In printing, as is well known, the container is held by a container chuck device (not shown because it is a well-known device) that holds the container opening 1 and the shoulder portion 2, and the container chuck device is rotated in synchronization with the printing device. Then, a pattern, a character, and the like are printed on the cylindrical surface of the body 3.

At this time, a positioning jig (not shown) provided on the container chuck device engages with the positioning mark 14 of the container, maintains the container at a predetermined angular position, and fixes a predetermined position on the surface of the body 3. Printing is applied to the location. After printing, body 3
Is sealed, and a tube container A having a printed surface is completed.

When using the tube container A, the cap B
When the cap B is rotated and descends to a predetermined position when the screw B is screwed into the container opening 1, the inner surface of the stopper rod 24 rides over the engagement piece 12, and the side surface contacts the stopper 11, and the cap Will stop rotating. Before positioning when lowering the cap, the alignment mark 14
Is an extension of the stopper 11a, so that it does not engage with the lower end of the stopper rod 24 like the stopper 11a.

Looking at the external appearance of the container opening 1 when the cap is removed, the alignment mark 14 has a stopper 11a.
Since the stopper 11a is simply extended in appearance, it is not particularly noticeable in design.

The container of the present invention is not limited to a tube container, but can be applied to an injection-molded circular container or a blow-molded circular container. It is only necessary to form the stopper of the cap positioning member so as to extend it.

In the above embodiment, the cap is provided on the top wall of the cap. However, the cap comprises a cap base and a hinged opening / closing lid attached to the base. An upper wall provided with an opening through which the extrusion cylinder is inserted may be provided at the center, and a top wall provided with a stopper closing the extrusion port may be provided on the opening / closing lid.

[0016]

Since the present invention is configured as described above, it has the following effects. Since the stopper of the cap positioning member provided at the shoulder wall step at the lower end of the container opening is extended outward and the extended portion is used as a printing positioning mark, the positioning mark also serves as the stopper of the cap positioning member. As a result, there was no sense of incongruity in the design, and the product value could be increased.
