Description

Technical area

The invention relates in particular to a plastic container for receiving bulk material, in particular a bottle for holding a liquid.

State of the art

In the prior art, the most diverse plastic containers for receiving bulk materials, in particular bottles are known. They usually have an integrally formed container body and a lid produced separately from the container body. The lid may be formed, for example, as a screw cap or as a snap hinge closure lid.

US 6,772,902 and US 6,398,067 disclose containers having a cup-shaped body and a snap hinge closure integrally formed on the body, the body having a closed bottom formed on the shell of the body.

US 5,270,011 shows a reaction vessel made of plastic with a downwardly tapered, closed body end.

US 0'4796'766 describes a plastic bottle with a separate screw cap, wherein the bottom of the bottle is provided with a steel bottom.

These containers are each filled through their filling opening, which is then closed. This is relatively time consuming. Furthermore, there is the danger that the closure at the bottler not properly applied and thus entire series can not be used.

DE 201 13 986 shows a container for small portioned media, with a receiving body whose filling opening has a peripheral stand collar, said filling opening is arranged on the opposite side of the already closed removal opening.

The US 4'990'016 also shows a container which is filled by the opposite side of the closure opening. The tip of the removal opening is connected via predetermined breaking points with the rest of the neck.

Presentation of the invention

It is therefore an object of the invention to provide a plastic container which is easy to fill and is easy to close both during filling and in later use.

This object is achieved by a plastic container having the features of patent claims 1, 15 and 20, respectively.

The plastic container according to the invention has a container body forming a reservoir with a removal opening and a lid closing the removal opening. On the side facing away from the removal opening, the container body has a filling opening, which is tightly closed with a separate closure element. The lid and container body are formed integrally together. Between lid and container body an integrity guarantee element is formed, which can be removed when first opening the container. The Undertaking guarantee element is a plastic strip, which is connected via predetermined breaking lines with the lid and / or the container body.

In a further variant of the invention, the plastic container has a container body forming a reservoir with a removal opening and a lid closing the removal opening. On the side facing away from the removal opening, the container body has a filling opening, which is tightly closed with a separate closure element. The lid and container body are formed integrally together. The container body has a neck with an external thread and the lid has a matching internal thread.

In a further variant of the invention, the plastic container has a container body forming a reservoir with a removal opening and a lid closing the removal opening. On the side facing away from the removal opening, the container body has a filling opening, which is tightly closed with a separate closure element. The lid and container body are formed integrally together. The lid is a snap hinge closure integrally formed with the container body and having a lower part and a top part arranged pivotably on this via a hinge.

The closure element is preferably a foil or a pane, for example made of aluminum or plastic. However, it may also be a screw cap, a snap cover or other closure element. The snap cover can be plugged onto the container body or molded onto this.
The container is produced with a closed removal opening, wherein the lid closes this removal opening. The container thus has after its manufacture and before and during its filling a closed removal opening.
Because the filling opening and the removal opening are not identical, the container can be produced with a closed removal opening. The tightness can thus be guaranteed by the manufacturer and does not depend on the care of the bottler. Furthermore, the tightness is improved.

The filling opening can be made relatively large, since they do not later serve as a removal opening and thus no requirements must be placed on their diameter with respect to the distribution. Furthermore, the removal opening can be made arbitrarily small, since they do not have to serve as a filling opening.

The closing of the filling opening by means of a film is simple, time-saving and cost-effective. In addition, the tightness can be better ensured.

It is advantageous that lid and container body already form an integral container when delivered to the bottler and thus always in the same number and matching each other.

A further advantage is that the plastic container can be easily provided with an integrity guarantee element and that only a single such element is sufficient to show that the container and its contents have not been manipulated. The integrity guarantee element separates the lid from the container body, and only its removal allows the lid to be placed on the container body for reclosability of the container.

Another advantage is that the variety in the design of the container and in particular its lid are no limits. In particular, the shape of the lid can be changed without too much effort. Preferably, the container is designed as a standing container, wherein the closure element forms the bottom.

The container according to the invention is particularly suitable for receiving liquids and lotions, but also for bulk goods such as candy or rolls such as wet wipes.

Further advantageous embodiments will become apparent from the dependent claims.

Ways to carry out the invention

FIGS. 1 to 5 show a first exemplary embodiment of the plastic container according to the invention. The container is preferably made by known techniques by injection molding. It essentially has a reservoir body 15 forming a container body 1 with a removal opening 16 and a lid 2, wherein lid 2 and container body 1 are formed integrally together. The container body 1 as well as the lid can have any desired shapes, as long as the lid 2 is suitable for later closing the removal opening 16.

In this example, the container body 1 is formed substantially truncoconical. But it can also be designed, for example, cylindrical. There are also curved shapes, such as a U forming hollow cylinder, possible, so that it is similar to a cornucopia.

The container body 1 is open at both ends thereof. The one end, as mentioned above, the removal opening 16. The other opposite end forms a filling opening. This other end is in this example, see Figure 3, an open, circular bottom. However, the floor may have a different shape, for example it can be angular or oval. It is sealed after filling the storage space 15 with a closure element, here a film 4. Preferably, the film 4 is welded to the container body 1. However, it can also be glued.

In order to enable a simple application of the film 4, the jacket of the container body 1 has an outwardly projecting, circumferential flange, which serves on the one hand as a foot 12 for placement of the filled container and as a support surface for fixing the film 4.

At the opposite end of the bottom of the container body 1 tapers via a shoulder 10 to a spout or a neck 11, which encloses the removal opening 16. On this neck 11 a circumferential band 3 is molded, being connected via thin points with the neck 11. These thin areas form predetermined breaking points in order to be able to remove the band 3 from the neck 11 when it is first opened. The band 3 is preferably narrower than the diameter of the neck 11. The band 3 has a protruding tab 30 or handle so that it can be held between two fingers to open the container so as to pull the band away. This is clearly visible in FIG.

On the opposite side of the neck of the band 3 3, the lid 2 is also molded over acting as predetermined breaking points thin spots. However, it is also possible that the band 3 remains an integral part of the lid 2 or the container body 1 and thus is connected to one of the two parts via predetermined breaking lines.

In the example shown here, the lid 2 has a majority cylindrical shape, wherein it is provided on the side facing away from the container body 1 with a closed top surface 21. Downwards it is open, with its lower end is designed as a plug-in sleeve 20 whose outer diameter corresponds approximately to the inner diameter of the neck 11. Between insert sleeve 20 and top surface 21 circumferential ribs 22 are present, which increase the grip of the lid 2.

As can be seen in particular in Figure 1, the container is sealed after its preparation in the region of the lid 2, without the cover 2 must already be slipped over the removal opening 16. As a result, without further measures, the container can be filled from the other end and this end can be easily sealed by means of a film 4.

When first opening the container, the band 3 must be removed to expose the removal opening 16. The band 3 thus acts as an integrity guarantee element. If the band 3 is completely removed, the lid 2 becomes a part independent of the container body 1 and is now available to close the container body 1 again. This situation is shown in FIG. In the example described here, the lid 2 was before the first opening of the container in the direction of its use position, but spaced by the band 3 to the neck 11. It can thus be lowered as a snap closure in this position on the container 1 and inserted with its insertion sleeve 20 in the neck 11 to close the container.

Depending on the shape of the container body 1, it can also be provided with a label or printed. This label is in this example a tube 5, which is slipped over the body 1 and shrunk into its desired shape. Preferably, the tube 5 has windows 50, through which the plastic of the body 1 can be seen. This tube 5 is clearly visible in FIGS. 4 and 5. He is not attached to the body 1 in this example, but is only at its lower end on the foot 12 of the body 1 on. However, it is possible to glue the hose 5 or otherwise secure.

FIGS. 6 to 9 show a second exemplary embodiment. The same parts as in the first embodiment are denoted by the same reference numerals and will not be repeated in detail here. The container according to these figures differs from the first example in the design and the arrangement of the lid 2.

Here, the cover 2 has an internal thread 23 and the neck 11 a matching external thread 11 'on. Also, this cover 2 has ribs 22 to increase the grip, but these ribs 22 are now parallel to the longitudinal axis of the container.

In the production of the lid 2, as can be seen in Figures 6 and 7, arranged in reverse position to its subsequent use position over the container body 1. That is, the upper deck surface 21 faces the container body 1 and the shell of the lid 2 projects beyond the top surface 21 in front of the first opening.

In later use, i. in the use of the lid 2 for re-closing of the container body 1, the lid 2 is screwed onto the neck 11, as can be seen in Figures 8 and 9.

Of course, plug-in covers can also be sprayed onto the container body in this inverse use position or screwable lid in the direct position of use. Other closure types can also be used as covers, in particular snap-on lids can be used.

The third embodiment, which is shown in Figures 10 and 13, has such a snap hinge closure. Again, like parts are designated by the same reference numerals as in the above examples.

This container also has a container body 1 with a foot 12 and after filling of the storage space 15 of the soil defined by the foot with the film 4 is sealed. The container body 1 again has a taper at the opposite end, which ends in a neck or a pouring or pouring spout 13. The shoulder around the Ausschütttülle 13 forms to the outside a collecting tray 14. This shell 14 may have a, as shown here, straight bottom. she can However, also have an inwardly curved bottom to better collect the cargo S.

The cover 2 is formed integrally with the container body 1, wherein it is here formed directly on the container body 1 without any intermediate tape. The cover 2 has a lower part 6 and an upper part 7, which are pivotally connected to each other via a snap hinge 8 of known type, here a toggle snap hinge 8. The upper part 7, as can be seen in FIG. 10, has a protruding nose 70 for facilitating the opening of the lid. The lower part 6 is provided with ribs 60 for the same purpose in this area. Lower part 6 and upper part 7 are shaped so that the cover 2 forms a cavity in its closed state, which serves here as a removal chamber 9, as will be explained below. Removal chamber 9 and storage space 15 are separated from each other by the wall of the collecting tray 14, as shown in Figure 11.

The lower part 6 is formed on the container body 1 and thus forms its extension. The Ausschütttülle 13 protrudes into the removal chamber 9. It thus protrudes into the lower part 6 or they can depending on the shape of the lower part 6 and the upper part 7 even project beyond the lower part 6. However, the Ausschütttülle 13 is not closed by the upper part 7, but ends free in the removal chamber 9, wherein their distance is such that stored in the storage unit cargo can pass through the spout 13 in the removal chamber 9 when panning or shaking the container. This is clearly visible in FIG. It is also conceivable that its upper end is covered by the upper part 7. In this case, the Ausschütttülle 13, however, has lateral openings through which the bulk material stored in the storage space 15 can escape into the removal chamber 9.

The snap hinge closure may or may not be provided with a tamper evident element. This element may be constituted by a tamper-evident band or other means known in the art which indicate whether or not the top has been lifted from the bottom. Furthermore, the upper part or the lower part with a sealing lip or another be provided with appropriate means to airtight to close each other. Furthermore, the Ausschütttülle 13 also, preferably before filling the storage space, be closed with a film. However, this film is detachably arranged so that the removal opening can be exposed.

This container is particularly suitable for pourable piece goods such as candies or dragees. By pivoting or tumbling the container once or several times with the lid closed, at least one article S passes into the removal chamber and is ready in the collecting tray. If the lid is now opened, you do not have to reach with your hand into the storage room, but only into the drip tray to remove the desired piece goods S. This is clearly visible in FIGS. 12 and 13. The storage room is less contaminated and the piece goods S remain hygienic fresh longer. Furthermore, if the container is overturned with the lid open, less piece goods may be spilled. This is particularly advantageous during a car, train or boat trip. Of course, here are the design of the lid and the container body hardly limits. Also, the purpose is varied.

The inventive container is thus easy to fill and easy to close after filling as well as in use.
