Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the packaging industry, and more particularly to cosmetics, drugs, detergents and foods, creams, paste jellies, powders, ointments and to some extent It also relates to molded plastic pots with lids for selling industrial products such as fluid emulsions, milk, processed foods, and paints.

This invention can be summarized as follows. That is, the present invention provides a casing covered by a casing lid, in which the casing lid is supported around a horizontal joint with an elastic snap-fit sealing mechanism that can be released by finger manipulation of an outwardly projecting protrusion. A packaging bore for selling various products, consisting of a container housed within a body. The container is secured in a ring comprising a lower annular member integral with the container and an upper annular member for pivoting, connected to the lower annular member by a flexible hinge band. Each of the two annular parts is provided with a complementary snap-fastening element, the top of the casing body is secured around the lower annular part, and the bottom of the casing lid is secured around the upper annular part. has been done.

[Prior Art and Problems to be Solved by the Invention] In order to sell products of this type, especially to the general public, efforts have been made to make them as attractive as possible and to give them a striking appearance at the lowest possible price. being done. If the products involved are manufactured on a large scale, a unique packaging is created for each product. However, when products are produced on a relatively limited scale, as is the case with most cosmetics, drugs, detergents, or processed foods, packaging can be standardized and used to differentiate between products on the same production line or between different products. It is common practice to differentiate each category by attaching a special label to it. However, as a result of this standardization, it is inevitable that the unification of expressions will reduce its appeal.

In the present invention, when assembling a very small number of elements to make an inexpensive packaging pot, some of the elements are standardized and produced on a large scale, while other parts are made into specific products.
This attempts to overcome the above-mentioned drawbacks of conventional pots by giving each product a unique character.

It is an object of the invention that the casing lid is pivoted around a horizontal joint with an elastic snap-fit sealing mechanism that can be released by manual manipulation of an outwardly projecting projection. To provide a packaging pot for selling various products, comprising a container housed in a casing body covered with a lid.

[Means and effects for solving the problem The three pots are characterized by a lower annular member that is integrated with the container, and an upper pivot member that is connected to the lower annular member by a flexible hinge band. The container is secured in a ring with an annular member, each of which is provided with a complementary snap-fastening element, and the top of the casing body is attached to the lower annular member. and the bottom of the casing lid is fixed around the upper annular member.

In a preferred embodiment, the element snapping the two annular members relative to each other comprises a strip from which one of the annular members extends, which retracts against elasticity into the pot when pressed with a finger; Near the extension, there is an outwardly directed terminal hook which forms a push button between the casing body and the casing lid that projects outwardly from the pot and releases the snap fastening, thereby applying a unidirectional force. Extending from the other annular member is a hook acting in the opposite direction.

To prevent the risk of young children accidentally opening the pot, pots of this type can be provided with two symmetrical snap fastening devices in opposing positions on each side of the hinge strip. It is therefore necessary to press both snap fasteners simultaneously in order to loosen the lid and release the pot.

For low-cost industrial production, the pot according to the invention consists of a standard container-ring assembly and interchangeable casing elements, i.e. a casing body and a lid that can be respectively adapted to the upper and lower annular parts of the ring. do.

In a simplified embodiment, a pot according to the invention can be made with only three elements: a one-piece container and ring molding, a casing body to be applied thereon, and a lid for the casing.

To ensure a good leak-free seal of the container during the entire life of the pot, the container can also be provided with a cover that fits over the neck of the container and is fixed to the annular member on the top of the ring.

In order to create a completely sealed state that will not leak until the first time it is used, a removable protective sealing cap is attached using elasticity to the annular groove made at the top of the neck of the container.
A lifting protrusion can also be provided on the outer surface of the upper part.

According to the practical construction form, this protective seal cap is made into a dish shape, and the entire lifting protrusion is housed in the hollow part, and it is sealed on the outer peripheral edge of the protective camp and can be torn off. A security membrane keeps the pot out of reach until the first time it is used.

To provide customers with evidence that the sealing mechanism has not been tampered with, a guarantee membrane that tears off the first time the pot is opened is placed on the edge of the neck of the container and, if necessary, around the protective cap. It can be pasted.

〔Example〕

The present invention will be described below based on drawings showing embodiments.

Corresponding elements in these drawings are numbered the same. The individual dimensions and proportions of these elements are not shown in real life in order to provide a clear understanding of the drawings.

The packaging pot shown in these drawings consists of two coaxial annular members with substantially vertical skirts, viz.
It consists of a lower annular member 8 extending from the outer wall of the housing and forming an extension of a horizontal annular flange 20, and an upper annular member 9 connected to the lower annular member 8 by a flexible hinge band 4. Ru.

The opening at the top of the casing body 2 is connected to the lower annular member 8.
The bottom opening of the casing lid 3 is snap-fitted around the upper annular member 9.

On the opposite side of the hinge band 4, the extension of the upper annular member 9 forms a hook 5a, flat on the inside and on the outside, which hook can be lowered when the two annular members 8, 9 are assembled one above the other. Coincident with the side annular member 8, it engages with a hook 5b extending just from the lower annular member 8 and facing inward to form a sealing mechanism with a snap action.

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

The casing body 2 and the casing lid 3 are latched onto the lower annular member 8 and the upper annular member 9 of the ring 7 in the usual adjusting lip and groove assembly 15.16. However, the sealing mechanisms 5a and 5b at opposite positions of the hinge band 4 are separate (FIG. 2), and in this case, the annular member 8.9 is designed to be freely deformable for the purpose of convenient handling. Also, the axial alignment between the original body 2 and the casing lid 3 is ensured.

In the vicinity of the hinge band 4 and the sealing mechanisms 5a and 5b, the main body 2 and the lid 3
The wall thickness is reduced by 28, 29 and 30, 31.
This is because it not only improves the joining operation but also allows easy access to the protrusion 6 when opening the pot. Therefore, the tips of the protrusions 6 do not protrude from the outer periphery of the pot, making it easier to fill the pot, while also serving to protect against accidental impacts.

The centering of the upper annular member 9 over the lower annular member 8 and the resulting centering of the lid and the main body when the lid 3 is placed over the main body 2 creates an annular shape that is in contact with each other when closed. two complementary conical portions 1 at the lateral ends of members 8, 9;
It becomes certain because the 9s interact with each other.

The outer end of the upper annular member 9 extends to form a notched annular inner flange 21, and the cut portion thereof extends to form an inwardly directed hook 22. For such an arrangement, a flat dish-shaped annular side wall 23 is provided with a protruding flat top wall 2 of the cover 11 which fits over the top of the container 1 from the outside.
4 is fixed by a snap action, and as a result, even when the pot is used with the lid closed, a leak-free sealed state is maintained. Inside the casing lid 3 there is a coaxial annular flange 25 whose free edge is connected to the hook 2.
2 and the top wall of the cover 11 near the wall 23 of the cover 11, so that the pot cover 11 effectively remains in the upper annular member 9 even during repeated opening and closing handling of the pot.
and the casing lid 3.

The inner edge of the container l is recessed to create an annular shoulder 26, which serves to support the peripheral edge of the flat, dish-shaped protective cap 12. A rib protruding outward from the bottom plate of this protective cap snaps into a groove 27 cut in the edge of the side wall of the container 1.0 Hand-held protrusion 1
3 extends from the inner surface of the bottom wall of the protective cap 12, which facilitates the removal of the cap during first use.

This protective cap 12 protects the pot during its entire storage period.
Guarantees a completely leak-free seal. Since the protrusion 13 does not extend beyond the top edge of the plate of the protective cap 12, it is possible to attach the guarantee film 14 by heat sealing or adhesive fixing onto the end face of the flange around the protective character 1120. 13 and remove the protective cap 12, the first user has to break the membrane 14, so that there is evidence of destruction beforehand to insure the user against fraudulent opening of the pot. It will remain.

FIG. 6 shows an alternative structure that seals with a snap fit. In this embodiment, the unyielding hook 50
a of the horizontal push button 60 extending from the upper annular member 9 and connected to the lower annular member 8 by a vertical flexible piece 110 bounded by two parallel slides 111, 112 of the lower annular member 8; Square notch 50b made on the inner terminal
In an alternative in which this hook is secured with a snap fit, the push button for opening the casing is integral with the casing body instead of the lid of FIGS. 1-5.

In the embodiment illustrated here, the container 1 and the ring 7 are molded into one piece, but the container and the ring are made separately and then bonded with adhesive or ultrasonic welding which requires additional work. It is also conceivable to assemble it using a well-known technique.

Furthermore, instead of being latched onto the upper annular member 9 as illustrated, the cover 11 can also be secured to the casing lid 3 by snapping, gluing, welding or other known techniques. It is also possible to form the lid 3 and the cover 11 into one piece. However, in general, the cover 11 is attached to the ring 7° container 1. and/or it appears preferable to make the lid 3 from a more flexible material by a molding operation.

Flexible materials such as polyethylene hold together well over multiple uses and are therefore more leak-tight than materials with an attractive appearance, high stiffness, and relatively high hardness such as polypropylene. However, from an economic standpoint, these properties of polypropylene are more favorable for the appearance, decoration and consistency expected of a pot of good quality and appearance.

Furthermore, the security membrane 14 can also be applied as a sufficient seal on the edge surface of the neck of the container 1 without the protective camp 12. For this purpose, the annular shoulder 26 on the inner edge of the container 1 is made in a groove of sufficient size so that the edge surface of the neck of the container is higher than the edge surface of the peripheral flange of the protective cap 12. There is a need.

When latching this cap into the groove 27, it is also possible to seal the security membrane 14 onto both edge faces simultaneously, provided that the neck of the container and both sides of the latched protective cap are at the same level. .

As can be seen from the following, the container 1 and the casing 2.3 do not necessarily have to be made to have similar shapes.

When connecting the container and the casing with the ring 7, different adaptations are possible, such as for example rotating cylindrical containers, polygonal or oblong casings.
