Hermetically sealed container with intact lock, opening device and attached retaining bracket

The hermetically sealed containers are finding increasing use in both industry and services. It is relatively easy to make a hermetically sealed container, all refreshing Drinks, canned food and a large number of items can be found if you can counter adulteration or changes wants to protect the environment, so their use. A hermetic seal alone is not particularly difficult to reach. Nevertheless, if the hermetic seal is to be maintained in the container, under the large number of airtight containers very little left.

Careful design, a thorough study of the shape and material are necessary to make a container which, once opened, continues to meet the conditions of the hermetic seal in the course of the Time met, but there are many applications where this condition is necessary. A few examples should be mentioned

"V

le from everyday life: When transporting strong caustic alkalis, which are so much used in electroplating plants, it is absolutely essential, and so in many cases the regulation requires that it is transported in hermetically sealed and tamper-proof containers / but once in Once at the factory, no one cares much about whether the container is left open with exhaust fumes or a possible risk of accidents or dangerous situations
Represents manipulations.

Other examples could be given where these
Precautions are required, as is the case with comparable chemical products where
a hermetic seal or keeping away from atmospheric constituents is necessary, as is the case with paints, varnishes,
Salts, water-repellent compounds and much more is the case.

This twofold requirement of the hermetic seal
before and after breaking the seal is a useful and practical requirement that can be considered indispensable in certain areas of application.

The integrity of the content is another necessary condition if you want to protect it against possible fraudulent manipulation. With all quality goods, be
be it a liquid or a solid substance, hermetic and inviolable protection is common. The better the closure is conceived, the more difficult it will be to tamper with the contents and the more certainty the customer has that what he is buying is an original product and the more secure the manufacturer is from being malicious and dishonest competition loses its brand reputation.

The more difficult it may be to open the container without completely or partially destroying the closure, the more difficult it will be its content will be safer. Now the mistaken idea is sometimes held that the more the cost of a thing increases Conditions it fulfills, and this principle is by no means universally applicable, because in many cases it is just a question that is thorough investigation and skillful planning.

Is the inaccessibility or tamper-proof security without destruction Once the seal has been reached, it is logical, especially with regard to the type of container with multiple uses and permanently hermetically sealed to think that the container must open. And the opening process must be designed to be easy, convenient and is effective without undue effort or unnecessary use of equipment or tools and without undue effort Costs.

Another factor to consider in order to keep the cost of the product to a minimum is its handling, and in this particular case a retaining bracket was designed that is created using the same injection molding principle as does not add more to the price than the weight of the material, without any preceding and additional operations Costs.

The hinge effect of the retaining bracket is achieved with a constriction in the thickness of the material, which is so appropriate is that it is given the said suitable hinge effect, the design of which gives it the necessary robustness, at the same time also the required flexural elasticity.

The hermetically sealed container according to the invention with tamper-proof closure, opening device and attached Retaining bracket · meets the stricter requirements

3U1794

the inaccessibility or security of intervention. Without destruction the closure, access to the interior of the container is not possible, but the container preserves the Hermetic sealing of the contained product regardless of the number of opening and closing operations.

The technical description now follows with reference to FIG FIG. 1, in which an overall view, section and detail of the container 1 and the closure lid 2 are shown.

The container 1 made of a suitable plastic material is practically frustoconical and has on its upper part an edge beading or grooving, which, formed by a projection, is an upwardly open U-profile insertion groove forms.

In this fluted groove 3, which acts as a receiving closure part, fits exactly the side profile of the cover 2, the is created in complementary form so that the corresponding parts when mating a hermetic seal form.

This carefully formed complementary form has im Cut two curved zones with an inclined orientation and a tight seal, in and on its main surface The lower part has an insertion groove and positioning parts are arranged, which ensure the hermetic seal and security of the lock.

On the outside of the container 1 and diametrically opposite project two approaches 4 of a suitable thickness, which for the bracket 5 as Serve carrier. This retaining bracket has been designed with the basic requirement not to increase the cost of assembly, since it was already manufactured using the same injection molding principle and no longer an additional process

_r _ 3U179A

is necessary.

The constriction or thin point 6 is shown in detail in FIG. 5 and in its interrelated arrangement in FIG. 4 shown; it is described in detail below.

The embodiment shown is twofold Basic condition has been met, a hinge effect and adequate flexibility when used as intended. Both properties are necessary for the whole to work well. The hinge effect becomes with the constriction or thin point 6 in the material thickness, as shown. With the given material properties and the extension of the thin point, the bracket has the required robustness. As noted before, At the same time, it has sufficient elasticity to allow the flexural elasticity necessary for transport.

This absolutely original, effective solution represents a fundamental one Detail without significant additional product costs and is the subject of a special claim.

In the middle part of the bracket there is a handle, which serves a dual purpose, namely to reinforce the arch of the support bracket and a more comfortable support, and has the position shown in Fig. 4 at rest and when stacking. During transport, the retaining bracket takes an orientation parallel to the rib 4, as shown in FIG. Grasping the handle with your hand · 5 increases the given technical and operational requirements of the building materials and the selected shapes of the retaining brackets shown control and makes a light, comfortable and safe transport possible.

Fig. 1 shows that the container bottom 11 has a corrugation which prevents any sideways movement of the containers when they are stacked on top of each other.

At the same time, ribs 10 and a spherical cap base 9 are provided, which adequately reinforce this area of the container and reinforce. The cover 2 also assumes a convex shape 7 in its closure area, which is similar to that of the bottom remind. Some ribs 8, distributed over the circumference of the cover, help ensure that it retains its flat shape.

With the one detailed in the previous sections Design of the retaining bracket, which, as already said, is also made by the injection molding process Stacking is possible without disturbing the outside and side of the bucket or container, although it is centered during transport and aligned perpendicular to the plane of the lid, making it easy, convenient and safe to use is achieved.

Therefore, the retaining bracket according to the invention is not a secondary one Addition or not a necessary addition, but rather forms an essential part of the invention and its design was done carefully so that it would serve its purposes completely satisfactorily without disturbing or additional To incur costs.

Particular reference is to be made to the two grooves 20 which enclose the opening fold 21 between them, the purpose of which was earlier was described when the closing and opening operation of the lid (Fig. 4) was described.

In Fig. 2, the lid and locking device of the system is shown in elevation.

Let us begin with the description of the closure piece 3, which is drawn out in section on a large scale in FIG. This piece has a ring 12, associated - Fig. 2 one frontal recess 13 and another peripheral part 14 (Fig. 3). If one pulls vigorously on the ring 12, the folded rim 3 breaks frontally at its weakest point as well as the Groove 13, and upon further actuation it tears lengthways through the circumferential weak point 14, and the ring 12 remains in the hand, as well as the folded rim 3, and thus the cover 2, FIG. 3, is completely accessible.

Well, it can be seen that the hermetic seal is not thereby canceled, since the cover 2 continues to be at least holds three areas in hermetic contact, indicated by arrows 15, 16, 17 (Fig. 3).

The thickest edge of the top of the frustoconical Container 1 is a fitting part · and fits on its entire circumference - except for the three named places perfectly to the lid, which has a complementary profile.

In the same Fig. 3, another vessel 18 is shown, which corresponds to a new container to be able to show how the stacking is done. Deserves special attention the analysis of the function of the grooves 11 that prevent the slipping Prevent one container on top of the other, which increases the necessary stability of the stacking tower. Likewise is the retaining bracket 5 shown in order to make it clear that it does not interfere with said process.

Fig. 4 illustrates the process of opening the container. It can be seen that, thanks to the fold 21 and the associated grooves, by simply lifting the fold it is extreme is easy to open the whole thing. This fact enables easier handling, eliminates the necessary

3U1794 44

The ability to use any tool and help ensure that the lid lasts indefinitely without losing the Container loses the necessary requirements for the hermetic seal.

In the upper part of the lid and to find the area for the arrangement of the opening fold is an arrow 19, Fig. and 4, pressed on in relief.

Lastly and as a complementary, summary information is noted that has already been discussed in detail in Figures 4, 5 and 6 in addition to the earlier described details, to the, arrangement and placement of the hinge-like pivotable thin place in stacking and at rest (Fig. 4) The selected technical solution is shown in detail in Fig. 5, from which the flexibility can be derived, which enables the design and robustness that result when materials are chosen for the production, and finally (Fig. 6) the arrangement of this zone during the transport process. The raw materials used, which are adjustments, tolerances, perfections, capacities, etc. are the adjustments for each use and types of material to be included.
