Abstract

In the case of a crushable disposable bottle (1) with a syringe insert (3A) for removing a metered portion of liquid, the syringe insert (3A) being connected to a bottle neck (2), the syringe insert (3A to 3F) is provided according to the invention with a device (6A to 6F) for manually releasing the connection (7A to 7F). As a result, it is now possible to remove a normally non-removable residual amount (5) of a slightly viscous product - such as shampoo - in the area of the inner wall (4) of the spray insert (6A), which reduces environmental pollution. <IMAGE>

Description

The invention relates to a bottle according to the preamble of claim 1.

Bottles of this type are known in a large number of different designs, which are used to selectively remove a metered portion of liquid by pressing on the bottle wall.

The disadvantage of a slightly viscous product - such as shampoo - is that a non-removable amount of the product in the area of the inner wall of the spray insert is to be seen.

It is therefore an object of the invention to make the above-mentioned residual amount removable by simple measures in order to avoid additional environmental pollution for further use.

This object is achieved according to the characterizing part of claim 1. Further advantageous developments of the invention emerge from the subclaims.

Because the syringe insert is provided with a device for manually releasing the syringe insert connection, the remaining amount can now be removed by removing or opening the syringe insert from the bottle neck, as a result of which the remaining amount can flow out of the large opening of the syringe insert, for example at a shampoo on the palm of your hand, whereby the last residue can be used by rinsing with a little water.

Various devices for manually releasing the connection emerge from the subclaims.

The invention can be seen in more detail from the figures and the description of the figures using several exemplary embodiments.

1 shows a first exemplary embodiment of a crushable disposable bottle 1 with an injection insert 3A connected to a bottle neck 2. In the area of the inner wall 4 of the injection insert 3A, a residual amount 5 of a product that can no longer be removed via an injection opening 4.1 is shown. Because the injection insert 3A is provided with a device 6A for manually releasing the connection 7A, the remaining quantity 5 can be removed from the injection insert 3A - for example by draining off. The connection 7A of the syringe insert 3A with the bottle 1 essentially consists of sealing rings 8 which press against an inner wall 9 of the bottle neck 2. This connection 7A can be supported by a snap connection 10.

In order to remove the injection insert 3, a pull tab 11, which is connected to the injection insert 3A by connecting webs 12, is drawn in a circle, whereby the connecting webs 12 tear open and the injection insert 3A is thereby detached from the bottle neck 2. However, it can also be provided that the injection insert 3A is only designed to be hinged. For this purpose, for example, the areas A and B of the tab 11 can be firmly connected to the injection insert 3A, this area A, B then acts as a folding hinge (FIG. 2).

In the second exemplary embodiment according to FIG. 3, the area B is firmly connected to the injection insert 3B as a device 6B, as in FIG. 2, so that when the pull tab 11 is pulled, the injection insert 3B is pulled from the bottle neck 2.

4 to 8, a screw connection 13 being provided as device 6C for releasing the connection 7C, for example by means of four thread turns 14 at the end of the bottle neck 2 and with four corresponding threaded cams 15 , which are arranged on the inside of the injection insert 3C. To close the spray opening 4.1, a screw closure 16 is provided with a closure tap 17 closing the spray opening 4.1. Further details emerge from FIGS. 5 to 8, with FIG. 6 representing a top view of FIG. 5 and FIG. 8 showing a bottom view of the injection insert 3C according to FIG. 7. For a better turning off of the injection insert 3C from the threads 14, this is provided with a knurling 18.

FIG. 9 shows a fourth exemplary embodiment, in which a shrink film connection 19 or shrink tube connection 20 is provided as the device 6D for releasing the connection 7D, which has a separating perforation 21 for manually separating the connection 19, 20. The perforation 21 can be provided all the way round, the injection insert 3D then being removable, or the perforation 21 being interrupted at one point, as a result of which the injection insert 3D can be folded at this point. For this purpose, a corresponding marking can be provided on the connection 19, 20. For the connection 19, 20, an annular projection 22 is provided on the bottle neck 2, which communicates with a further annular projection 23 on the injection insert 3D, both projections 22, 23 being provided with an axial distance.

After the perforation 21 has been separated, for example by means of a fingernail, for the purpose of removing residual amounts, the injection insert 3D is manually pressed out on the annular projection 23. The projection 23 thus serves as a connection seat and for pressing out. The sealing ring 8 serves only as a liquid-tight connection.

10 shows a fifth exemplary embodiment. In this case, as a device 6E for releasing a connection 7E, an annular actuation projection 24 is provided, on which the injection insert 3E can be manually pushed out of the bottle neck 2, the connection 7E - formed from sealing rings 8 resting on the inner wall 9 of the bottle neck 2 - being released .

A sixth embodiment is shown in FIGS. 11 and 12. The difference to the exemplary embodiment according to FIG. 10 is that instead of a projection 24 a pull tab 25 is provided which is provided with a corrugation 26 for better grip. However, it can also be provided that the injection insert 3F is articulated at one point to the bottle neck 2.
