Description

SQUEEZABLE CONTAINER

The present invention refers to the packing tare, especially to the containers of plastic of cartridge-paper, cardboard or of various types of flexible, elastic materials.

It is known the problem due to the waste packing tare, e.g. plastic bottles or some other used containers that take so much place. The similar problem arises when containers are transported from the production site to their filling stations. Such a problem can be solved while manufacturing containers with the bellows type side walls of the container, together with some additional means to maintain the container in squeezed position (see the European application 1550612A1 , B65D1/02, publ. date 06-07- 2005). The bottle, described in this application, consists of the bellows type side walls, bottom, top with the neck and opening for filling and discharge the content of the bottle. Due to the specific form of the walls alike bellows folds, i.e. the upper walls of the folds are bent upwards while the lower ones are straight, such a bottle is capable to maintain the squeezed position during the transportation procedure from the production site to the filling station, also while disposing to the waste container.

The shortcoming of such the container is that the specific form of the bellows folds is insufficient guaranty to maintain the squeezed position of the container under the influence of strong impact, e.g. while throwing into the waste container.

The aim of the invention is to assure that the container will maintain its squeezed position under the impact, e.g. while throwing into the waste container.

The aim is pursued by the following means. In the container comprising the side walls of the form of bellows parallel to the bottom of the container, and the means maintaining the container in squeezed position, the said means consist of the projection, formed in the central part of the bottom and directed towards the inside of the container, and the hollow projection of the same shape formed in the central part of the top of the container, open by its bottom part into the inside of the container and capable to receive the said projection on the bottom of the container very closely. There are one or some protrusions formed on the faced to the inside of the container lateral surface of the projection in the central part of the bottom of the container, and also there are one or some cavities of appropriate shape on the lateral inside surface of the hollow projection on the top of the container. The shape, the size and the place of location of the cavities allow to closely receive one or some above mentioned corresponding protrusions formed on the lateral surface of the projection in the central part of the bottom of the container when the container is squeezed.

The perimeter of the protrusion or protrusions of the projection on the bottom of the container, and the perimeter of corresponding cavity or cavities of the projection on the top of the container may be rectangular, triangle, multangular, circular or of some other shape, while the protrusion or protrusions and corresponding cavity or cavities itself may be of rectangular parallelepiped, prism, cylinder, hemisphere, cone, pyramid or of some other shape.

For stronger fixing the container in a squeezed position, the protrusion or protrusions of the bottom projection and the corresponding cavity or cavities of the projection on the top of the container have the profile of sharp angle directed towards the bottom.

Furthermore, the protrusions of the bottom projection and also the cavities of the projection on the top of the container may be formed and located around the corresponding lateral surfaces of the projections on the bottom and on the top, in one or in some lines Further distinguishing feature of the proposed container is that the protrusions of the bottom projection may be located in one or in some lines around the lateral surface of the projection of the bottom of the container, while the cavity or cavities of the projection on the top of the container, formed in and located around the lateral surface thereof, are continuous.

Furthermore, both the protrusion or protrusions of the bottom projection and the appropriate cavity or cavities of the projection on the top of the container, formed and located around the lateral surfaces of the corresponding projections, may be continuous.

The container (Fig.1) consists of the bellows type side walls 1 , bottom 2 and top 3 with additional means to maintain the container in a squeezed position.

The additional means consist of the projection 4 formed in the central part of the bottom 2, directed into the inside of the container, and the hollow projection 5 of the same shape in the central part of the top 3 of the container, open by its bottom part into the inside of the container, with the opening 6 or the neck for filling and discharge the content of the container. The shape and the size of the projections 4, 5 are matched so that the projection 5 accommodates the projection 4 very closely. There are one or some protrusions formed on the faced into the inside of the container lateral surface of the projection 4 on the bottom 2 of the container, and also there are one or some cavities of appropriate form formed on the lateral inside surface of the projection 5 on the top 3 of the container. The shape, the size and the place of location of the cavity or the cavities allow to closely accommodate one or some corresponding protrusions of the projection 4, when the container is squeezed. The protrusions of the projection 4 and the cavities of the projection 5 may be of various shapes.

With reference to the Fig.3a, sharp angle profile cavities 7 are formed on the inside surface of the projection 5 of the top 3 of the container, with the sharp angle directed towards the bottom 2 of the container, which are capable to closely accommodate the appropriate protrusions 8 of the same shape, that are formed on the surface of the projection 4 on the bottom 2 of the container as per Fig.3b. There may be some cavities 7 and some corresponding protrusions 8 arranged in lines around the lateral surfaces of appropriate projection 4 and projection 5 (see Fig. 3a, Fig.3b), or there may be some continuous protrusions 8 and the corresponding continuous cavities 7 located around the corresponding surfaces of the projections 4, 5 (see Fig. 4a, Fig.4b). Likewise, there may be only one continuous protrusion 8 and the corresponding only one continuous cavity 7. The location and arrangement of the appropriate cavities 7 and protrusions 8 allow the cavities 7 to closely accommodate corresponding protrusions 8 when the container is squeezed.

Fig. 5a and Fig. 5b show the option of the invention, where the cavities 9 in the inner surface (see Fig. 5a) of the top 3 of the projection 5 of the container and the corresponding protrusions 10 on the surface of the projection 4 on the bottom 2 of the container are of rectangular parallelepiped shape and are located in appropriate places in one or some lines around the faced towards the inside of the container lateral surface of the projection 4 on the bottom 2 of the container, and around the inner lateral surface of the projection 5 of the top 3 of the container, in order the cavities 9 arranged in lines could closely accommodate corresponding lines of the protrusions 10 when the container is squeezed. Fig. 6a and Fig. 6b show the option of the invention, where the protrusions 10 of the projection 4 of the bottom 2 of the container (see Fig. 6b) are of the same shape and also are located and arranged in the same way as it is shown in Fig. 5b, while the cavity or cavities 11 of the projection 5 of the top 3 of the container are continuous, of rectangular profile and are located around the lateral inside surface of the projection 5 on the top 3 of the container, and the place of the location exactly corresponds the location of the lines of the protrusions 10 of the projection 4 on the bottom 2 of the container. There may be one or some lines of the protrusions 10 on the lateral surface of the projection 4 on the bottom 2 of the container and respectively - one or some continuous cavities 11 located in appropriate place around the inside lateral surface of the projection 5 on the top 3 of the container to closely accommodate corresponding protrusions 10.

The option showed in Fig. 7a and Fig. 7b is analogous to the option described in Fig. 5a and Fig. 5b, however the protrusions 12 and the cavities 13 are of hemisphere shape.

The option showed in Fig. 8a and Fig. δb is analogous to the option described in Fig. 6a and Fig. 6b, however the protrusions 14 of the projection 4 on the bottom 2 of the container are of hemisphere shape, while the continuous cavities 15 on the top 3 of the container are of semicircle profile.

One more option showing how to maintain the container in a squeezed position is presented in Fig. 9a and Fig. 9b, where the cavities 16 of the projection 5 on the top 3 of the container and the corresponding protrusions 17 of the projection 4 on the bottom 2 of the container are of triangle prism shape.

Fig. 10a and Fig. 10b show the option of the invention, where both the protrusions 18 of the projection 4 of the bottom 2 of the container and the cavities 11 of the projection 5 of the top 3 of the container are continuous, have rectangular profile and are located around the lateral surfaces of the corresponding projections 4, 5 on the bottom 2 and on the top 3 of the container.

Fig. 11a and Fig. 11b show the option of the invention, where both the protrusions 19 of the projection 4 of the bottom 2 of the container and the cavities 11 of the projection 5 of the top 3 of the container are continuous, have a profile of semicircle shape and are located around the lateral surfaces of the corresponding projections 4, 5 on the bottom 2 and on the top 3 of the container.

The neck 6 of the container or some additional projection (not indicated here) around the neck 6 on the top 3 of the container may serve as a projection 5 of the top 3 of the container matching the projection 4 on the bottom 2 of the container.

The perimeter of the protrusions 8, 10, 12, 14, 17, 18, 19 of the projection 4 on the bottom 2 of the container and respectively the perimeter of the corresponding cavities 7, 9, 11 , 13, 15, 16 of the projection 5 on the top 3 of the container may be rectangular

(Fig. 3a, 3b, 5a, 5b, 6b), triangle (Fig. 9a, 9b), circular (Fig. 7a, 7b, 8b), multangular (not indicated here) or of some other shape, while the projections 4, 5 may also be of different shapes not limiting the options by the given examples. Furthermore, in order to save the area for the squeezed container, there may be a cavity 20 on the top of the container, as per Fig.12.

The protrusions and the cavities may be formed in different ways: by pressing, shaving or milling in the walls of the projections 4, 5. While forming the fixing elements by the last-mentioned way, the walls of the projections 4 and 5 should be thicker. The projection 4 of the bottom 2 of container and the projection 5 of the top 3 of the container should be made of the material that enables to exercise the pressing, shaving or milling procedures, therefore this material may also be different than the material of container itself.

While squeezing the container (Fig. 2), the bellows of the side walls 1 become squeezed and due to the elasticity of the material the projection 4 of the bottom 2 enters into the projection 5 of the top 3 of the container, so, the protrusions 8, 10, 12, 14, 17, 18, 19 enter the appropriate cavities 7, 9, 11 , 13, 15, 16 allowing reliably to maintain the container in the squeezed compact position and not to expand under the stronger impact during transportation or while disposing to the waste container.
