Each of the two annular members is provided with a complementary snap fastening element, the top of the casing body being fixed around the lower annular member and the bottom of the casing lid being fixed around the upper annular member. Have been.

[Problems to be solved by conventional technology and invention]

Efforts have been made to provide products of this type, especially for the general public, at the lowest possible price, as attractive as possible and with a noticeable appearance. If the products involved are produced by large-scale production, each product has its own packaging. However, if it is produced on a relatively limited scale, as is found in most cosmetics, pharmaceuticals, detergents or processed foods, standardize the packaging to separate products or products on the same production line. It is common practice to use special labels to distinguish between categories. However, the unification of expressions resulting from this standardization inevitably results in reduced attractiveness.

In the present invention, when assembling a very small number of elements to make an inexpensive packaging pot, some of these elements are standardized and large-scale production is performed, but some of them are made into specific items, which are used to make individual products. An attempt is made to overcome the above-mentioned drawbacks of the conventional pot by giving a unique personality.

It is an object of the present invention that the lid of the casing is pivoted around a horizontal joint with an elastic snap-fit fitting that can be released by manual manipulation of the outwardly projecting protrusions. An object of the present invention is to provide a packaging pot for selling various products, comprising a container accommodated in a casing body covered by a lid.

[Means and actions for solving the problem]

One feature of the pot is that it has a single ring with a lower annular member that is integral with the container and a pivotal upper annular member connected to the lower annular member by a flexible hinge band. The container is stopped at the two annular members,
In each case a complementary snap-fastening element is provided, the top of the casing body being fixed around the lower annular member and the bottom of the casing lid being fixed around the upper annular member.

In a preferred embodiment, the element for snap-fastening the two annular members relative to each other comprises a strip with one of the annular members extending into the pot against elasticity when pressed with a finger, wherein the strips of the strips have Near the extension is an outwardly directed terminal hook, which forms a push button between the casing body and the casing lid that projects outward from the pot to release the snap lock, while A hook acting in the opposite direction and extending from the other annular member.

To prevent the danger of young children accidentally opening the pot, this type of pot can have two symmetrical snap fasteners at opposing positions on each side of the hinge band. Therefore, to release the pot by loosening the lid, it is necessary to push both snap fasteners simultaneously.

For industrial production at low cost, the pot according to the invention consists of a standard container-ring assembly and a replaceable casing element, i.e. a casing body and a lid which can respectively be fitted to the upper and lower annular members of the ring. I do.

In a simplified embodiment, the pot of the invention
It can be made with only one element, namely a one-piece molded product of a container and a ring, a casing body to be mounted thereon, and a casing lid.

Ensuring good sealing without leakage of the container throughout the life of the pot can also be achieved by attaching a cover to the container that fits the neck of the container and securing it to the annular member at the top of the ring.

In order to create a completely sealed state that does not leak until the first use, to the annular groove made at the top of the neck of the container,
It is also possible to attach a detachable protective seal cap using elasticity, and to attach a lifting projection to the upper outer surface of the cap.

According to a practical construction, the protective seal cap is dish-shaped, the entire lifting projection is housed in the cavity and sealed onto the outer peripheral edge of the protective cap. Possible warranty membranes ensure that the pot is not accessible until the first use.

To provide customers with evidence that the closure has not been tampered with, a security membrane that tears off when the pot is opened for the first time is placed on the edge of the container neck and, if necessary, around the protective cap. You can stick it.

〔Example〕

 Hereinafter, the present invention will be described with reference to the drawings showing examples.

In these figures, corresponding elements are numbered the same. The individual dimensions and proportions of these elements are different from the actual ones for a clear understanding of the drawings.

The packaging pot shown in these figures comprises two coaxial annular members, substantially in the form of a vertical skirt, the lower side extending from the outer wall of the container 1 and forming an extension of the horizontal annular flange 20. And an upper annular member 9 connected to the lower annular member 8 by a flexible hinge band 4. The opening at the top of the casing body 2 is
A snap fit is made around the lower annular member 8 and the bottom opening of the casing lid 3 is snap-fastened to the upper annular member 9.

On the opposite side of the hinge band 4, the extension of the upper annular member 9 is flat on the inside and forms a hook 5a on the outside, and when the two annular members 8, 9 are assembled one above the other, the hook is lowered. The lower annular member 8 which coincides with the lower annular member 8
Combined with the hook 5b that comes out from the inside and constitutes a sealing mechanism with a snap action.

At the upper part of the hook 5a, the protrusion 6 extending from the upper annular member 9 and protruding to the outside of the ring constitutes a manual push button, and when this is pressed, the upper annular member 9 near the hook 5a is elastically deformed. Thus, the latched sealing mechanism is freely released.

The casing body 2 and the casing lid 3 are latched to the lower annular member 8 and the upper annular member 9 of the ring 7, respectively, by the assembling methods 15 and 16 including ordinary adjusting ribs and grooves. (Fig. 2), apart from the sealing mechanisms 5a, 5b opposite the hinge band 4, the annular members 8, 9 are freely deformable in this case for the purpose of convenient handling. The annular joint shoulders 17, 18 ensure axial alignment between the casing body 2 and the casing lid 3, respectively.

The thickness of the main body 2 and the lid 3 are reduced 28, 29 and 30, 31 near the hinge band 4 and the sealing mechanism 5a, 5b to improve the joining operation and at the same time to open the pot when opening the pot. This is because it is easily accessible. Therefore, the tip of the protrusion 6 facilitates filling of the pot without protruding from the outer periphery of the pot, and serves to protect against accidental impact.

Centering of the upper annular member 9 on the lower annular member 8 and consequently, when the lid 3 is put on the main body 2, the centering of the lid and the main body is brought into contact with each other when closed. Complementary two conical sections 19 at the lateral edges of 8,9
Interact with each other to ensure certainty.

The upper annular member 9 extends at the outer end to form an annular inner flange 21 with a notch, and the stolen portion extends as an inwardly directed hook 22. For such an arrangement,
A flat dish-shaped annular side wall 23 snaps onto the protruding flat top wall 24 of the cover 11 that has been successfully placed over the neck of the container 1 from outside, and as a result the pot is closed with the lid closed. Even during use, a sealed state without leakage is maintained. Inside the lid 3 of the casing there is a coaxial annular flange 25, the free edge of which hits the hook 22 and the top wall of the cover 11 near the wall 23 of the cover 11, thus repeatedly opening and closing the pot. During handling, the pot cover 11 is effectively fixed to the upper annular member 9 and the casing lid 3.
And will be fixed to.

The inner edge of the container 1 is recessed to make an annular shoulder 26, here the flat dish-shaped protective cap 12 serves to support the peripheral edge. A rib projecting outward from the bottom plate of the protective cap snap-fits into a groove 27 in the side wall of the container 1. A hand-held projection 13 extends from the inner surface of the bottom wall of the protective cap 12, thereby making it easier to remove the cap during first use. This protective cap 12 ensures a completely leak-tight seal throughout the storage of the pot. Since the projection 13 does not extend beyond the top edge of the plate of the protective cap 12, it is possible to apply a heat-sealed or adhesively secured security film 14 on the end face of the peripheral flange of the protective cap 12. Hand-held projection
There is no evidence of destruction, which guarantees the user that the pot will be opened fraudulently in advance, as the first user will have to break the membrane 14 to reach out to 13 and remove the protective cap 12 Will remain.

FIG. 6 shows an alternative of the structure in which the components are sealed by fitting by snap action. In this embodiment, the flexible hook 50
a extends from the upper annular member 9 and is limited by two parallel slits 111 and 112 of the lower annular member 8;
This hook is snap fitted into a square cutout 50b made at the inner end of the horizontal push button 60, connected to the lower annular member 8 at 10. In this alternative, the push button for opening the casing is integral with the casing body instead of the lid of FIGS.

In the embodiment illustrated here, the container 1 and the ring 7 are molded integrally, but the container and the ring are separately manufactured, and then, an adhesive is used. It is also conceivable to assemble using a known technique.

Further, instead of latching the cover 11 to the upper annular member 9 as illustrated, the cover 11 may be fixed to the casing lid 3 by snapping, bonding with an adhesive, welding, or other known techniques. It is also conceivable that the lid 3 and the cover 11 can be integrally molded. But generally cover
It appears that it is preferable to make 11 by a molding operation with a material that is more flexible than ring 7, container 1 and / or lid 3.

Flexible materials, such as polyethylene, combine well over many uses and therefore have an attractive appearance like polypropylene, are more rigid, and are more leak-tight than materials with relatively high hardness. However, from an economic point of view, these properties of polypropylene are even more favorable for the appearance, decoration and viscous production expected of a pot of good quality and appearance.

In addition, a security membrane 14 can be provided as a good seal on the edge of the neck of the container 1 without the protective cap 12. For this purpose, the annular shoulder 26 at the inner edge of the container 1 is made in a groove large enough so that the edge surface of the container neck is higher than the edge surface of the peripheral flange of the protective cap 12. There is a need.

When this cap is latched into the groove 27, if the neck of the container and both sides of the latched protective cap are at the same level, it is possible to simultaneously seal the security film 14 on both edge surfaces. .

As will be readily understood, it is not necessary to make the shapes of the container 1 and the casings 2, 3 similar. The connection between the container and the casing by the ring 7 allows different adaptations, for example, a rotating cylindrical container, a polygonal or an oval casing.
