Description

[Detailed explanation of the idea] "Industrial application field" This case concerns liquid containers.

``Prior Art'' As this type of container, for example, the container disclosed in Japanese Utility Model Application Publication No. 58-130947 is known.

The container includes a container body in which a mouth and neck section with an engaging protrusion stands up from the upper end of the body via a tapered shoulder, and a container body that extends from the back surface of the top wall that closes the upper end surface of the mouth and neck to the outer surface of the mouth and neck. An inner circumferential wall to be fitted is provided vertically, and an engaging protrusion that engages with the lower surface of the engaging protrusion is provided around the lower end of the inner circumferential wall, and the lower end surface of the elastic outer circumferential wall that hangs down from the outer periphery of the top wall is attached to the lower end of the inner circumferential wall. It consists of a cap placed on the upper surface of the outer peripheral part of the shoulder part, and by pushing the outer surface of the opposing part of the lower part of the outer peripheral wall of the cap inward, the lower end of the outer peripheral wall is pushed up along the tapered surface of the shoulder part. The entire cap is raised by raising the outer circumferential wall by pushing up, and the lower end of the inner circumferential wall is disengaged from the mouth and neck, allowing the cap to be removed.

"Problems to be Solved by the Invention" The outer circumferential wall of the cap of the conventional container described above is formed so that it can rise along the tapered surface of the shoulder by pushing inward the opposing portions of the lower part of the outer circumferential wall, so it is formed to be elastically deformable. Moreover, since it hangs down from the outer periphery of the top wall that closes the upper end surface of the mouth and neck to the upper surface of the outer periphery of the tapered shoulder, its length in the vertical direction becomes large.
The cap has an engaging protrusion on the inner periphery of the lower end of the inner circumferential wall that hangs down from the top wall and engages with the lower surface of the engaging protrusion on the outer surface of the mouth and neck. In the conventional cap formed in this way, when the lower part of the outer circumferential wall is pushed inward and the lower end of the outer circumferential wall is pushed up along the upper surface of the tapered shoulder part and the cap is raised, the cap is exposed to the mouth and neck as described above. Due to the engagement between the outer circumferential wall and the inner circumferential wall, the outer circumferential wall tends to bend, making it difficult to raise the cap.If the rigidity of the outer circumferential wall is increased to eliminate this defect, the outer circumferential wall will not be pushed inward. It was difficult.

The present invention eliminates such drawbacks, makes it easier to open the cap, and makes it possible to make the overall shape of the container unique by making it different from the conventional shape.

"Means for Solving the Problem" A container body 5 that stands up a mouth and neck part 3 from the upper end of a body part 1 via a tapered shoulder part 2, and a container body 5 that is slidably fitted to the outer surface of the lower end of the mouth and neck part 3. flange-shaped base plate 10
An operating member in which an upper plate 8 protrudes in an outward flange shape from the outer periphery via an upright peripheral wall 9, and an elastic outer peripheral wall 7 is vertically disposed from the outer periphery of the upper plate, the lower end surface of which is placed on the upper surface of the outer periphery of the shoulder portion. 11, and a rod stopper 12 hanging down from the center of the top wall is fitted into the mouth and neck part 3, and the lower end surface is placed on the base plate 10 from the top wall portion surrounding the rod plug. Cap 1 hanging down the leg tube 13

"Operation" When the opposing portion of the lower part of the outer circumferential wall 7 of the operating member 11 is pushed inward from the mouth closed state of the container body 5 shown in FIG. When the operating member 11 is raised, the operating member 11 is raised, and the operating member 11 is raised, and the cap 1 is
4 can be pushed up and the cap can be easily removed.

``Embodiment'' The container of the present invention consists of a container body 5, an operating member 11, and a cap 14.

The container body 5 has a mouth and neck part 3 erected from the upper end of a rectangular cylindrical body part 1 via a tapered shoulder part 2. The upper end of the shoulder is formed into a horizontal plate part, and a small engagement protrusion 4 is provided slightly above the lower end of the mouth and neck, and a retaining protrusion 15 is provided around the outer surface of the upper end of the mouth and neck. ing. A cylindrical mouth forming member 6 may be fitted to the upper end of the mouth and neck part 3. This member is a soft synthetic resin member provided to ensure sealing of the mouth by the rod stopper 12 described below, and is preferably used when the container body 5 is formed of a hard material. This member has a fitting circumferential wall hanging down from the outer surface of the fitting cylinder to the inner surface of the mouth and neck via an outward flange, and a protrusion 16 provided around the lower end of the circumferential wall is connected to the retaining protrusion 1.
5 is engaged with the lower surface.

The operating member 11 has an upper plate 8 protruding from the outer periphery of a flange-shaped base plate 10 slidably fitted to the outer surface of the lower end of the mouth and neck part 3 in an outward flange-like manner via an upright peripheral wall 9. An elastic peripheral wall 7 whose lower end surface is placed on the upper surface of the outer periphery of the container body shoulder 2 is suspended from the outer periphery of the upper plate. The outer circumferential wall is cylindrical and has the same shape and size as the body 1, and by pushing the opposing portion of the lower part of the circumferential wall inward, the lower end of the outer circumferential wall rises along the tapered surface of the shoulder. , so that the entire operation member 11 rises with respect to the container body 5 due to the rise. The aforementioned small engagement protrusion 4 engages with the upper edge of the inner peripheral part of the base plate 10 with the lower end of the outer peripheral wall 7 in contact with the upper surface of the outer peripheral part of the shoulder part 2, and the operating member 11 It is designed so that it does not move blindly.

The cap 14 fits into the mouth and neck part 3 the rod stopper 12 suspended from the center of the top wall, and also places the lower end surface of the leg tube 13 hanging down from the top wall portion surrounding the rod stopper on the upper surface of the support plate 10. I'm leaving it there. The top wall has a rectangular shape similar to the outer surfaces of the body part 1 and the outer circumferential wall 11, and short circumferential walls are suspended from the outer circumference of the top wall. When the mouth forming member 6 is fitted to the upper end of the mouth and neck part 3 as shown in the illustrated example, the rod stopper 12 is fitted into the mouth forming member.

``Effect of the invention'' The present invention has the above-described structure, and the outer circumferential wall 7 for pushing up the cap can be slid freely toward the outer surface of the mouth and neck, instead of from the outer periphery of the top wall of the cap as in the conventional example. Since the fitted operating member 11 is suspended from the outer periphery of the upper plate 8, the length of the outer circumferential wall in the vertical direction can be made shorter than that of the conventional example, thereby reducing the deflection when the outer circumferential wall is pushed. This makes opening the lid easier. In addition, the fitting of the cap to the mouth and neck of the container body is achieved by engaging the engagement protrusion at the lower end of the inner circumferential wall hanging from the top wall of the cap with the lower surface of the engagement protrusion provided around the outer surface of the mouth and neck as in the conventional method. The rod stopper 12 hangs down from the top wall of the cap.
Since this is done by fitting the cap into the mouth and neck, the engagement of the cap with the mouth and neck does not become too firm, which makes it difficult to push up the cap by pushing the lower part of the outer peripheral wall. Furthermore, since the lower end of the leg tube 13 hanging down from the top wall of the cap is placed on the upper surface of the flange-shaped base plate 10 that is slidably fitted to the outer surface of the lower end of the mouth and neck part 3, the lower end of the leg tube 13 is placed on the base plate. The upper plate 8 protruding outward from the outer periphery in an outward flange shape via the peripheral wall 9 standing up from the outer periphery and the outer peripheral wall 7 hanging down from the outer periphery of the upper plate hide the upper end of the operating member 11 and the cap as shown in the figure. Even if a gap is provided between the lower edge of the outer periphery of the cap and the lower edge of the outer periphery of the cap, the appearance of the container will not become unsightly. Because the container is provided, and the structure can be recognized at a glance, there is an advantage that it can attract the attention of users or consumers as a container for storing special items.
