Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual device suitable for removing a cap from a bottle body,
In particular, the present invention relates to a manual device having a structure suitable for easily removing a metal cap from a container made of a plastic material which constitutes a drinking bottle used in an animal breeding department for small experimental animals such as mice, guinea pigs or other animals. Is.

2. Description of the Related Art Up to now, an operator of an animal breeding department has manually separated two parts constituting a drinking bottle to fill the drinking bottle. This operation may seem very simple, but if both parts are stuck together,
In practice, the result is often a disruption or difficulty in separation. This sticking may be due to several factors, such as the excess pressure already applied by the operator during the last assembly of the two components of the drinking bottle, or its misalignment, evaporation of the liquid contents of the container. This is a result of the presence of solid residue deposits on the neck of the container due to it, wear of the neck of the container and other factors. For these reasons, the operator must resort to inadequate means, such as pliers and pliers, to remove the metal cap from the drinking bottle container. That is, the lever of the metal cap tube must be applied, resulting in deformation and / or deformation of the metal cap.
Or it causes container damage, thus compromising the integrity of the drinking bottle, compromising its functioning, and replacing it with a new drinking bottle.

SUMMARY OF THE INVENTION To overcome the aforementioned drawbacks, the present invention provides a hand operated tool which effectively and easily removes a metal cap from a container made of plastic material. It is structured to ensure that. This device removes all the components of the drinking bottle without damaging them, thus guaranteeing a long service life and without any direct contact between the operator's hand and the metal cap, thus , Improve hygiene.

The specific outline of the manual device according to the invention will now be described in the following detailed description in connection with the accompanying drawings: FIGS. 1 and 2 respectively show a side view and a plan view of the device according to the invention. Figure 3 is an exploded view of the drinking bottle; Figure 4 is a side sectional view of the device applied on the cap of the drinking bottle before removing the cap of the drinking piston from the drinking bottle container. 1 and 2, the manual device according to the invention comprises a handle 1 which is substantially integral with a body 2 to which a ring 3 is fixed.
The inner diameter of the ring 3 is equal to or slightly larger than the outer diameter of the cylindrical wall of the cap 11 of the drinking bottle.

The main body 2 is provided with a cavity 2a extending in the direction of the handle 1 / ring 3 at the bottom thereof. The cavity 2a is open toward the ring 3, the other end is closed by the wall 2b, and the side wall is opened by the passage of the through groove 7. Inside the cavity 2a, the piston 4 tapered at 4a slides in the cavity, and the spring 5
Is located between the piston 4 and the wall 2b. The piston 4 is provided with a button type protrusion 6 and is integrated with the piston. The spring 5 stretches and pushes the piston 4 to one side, exits the cavity 2a and finally hangs on the wall of the hole 7 (see FIG. 1), and the hole 7 acts as a shoulder for the projection 6.

As can be seen in FIG. 2, the length of the piston 4 is such that when it is in the rest position, its protruding end extends considerably beyond the inner edge of the ring 3. With reference to FIG. 4, the operator applies the ring 3 of the device to the cap of the drinking bottle, then slides the ring 3 along the cap wall while holding down the pressure of the spring 5, and finally tapers the piston 4. The slanted end 4a is slid over the edge 15 of the cap 11.

When the operator slides the piston over the rim 15, the spring 5 biases (presses) the piston 4 against the body 12 of the drinking bottle while simultaneously hooking it on the rim 15 of the cap. The operator then only applies a lever action to the handle 1 to remove the cap. The piston 4 acts on the lower bottom end of the cap to easily remove the cap from the body of the drinking bottle. Once both parts of the drinking bottle have been separated from each other, the operator moves the button-shaped projection 6 to overcome the resistance of the spring 5 and retracts the piston 4 and then removes the ring 3 from the cap 11.

[0008] Commercially available laboratory drinking bottles, of course, have very different capacities from one another, but their caps have a constant size (in particular their diameter is constant).
It should be noted that we hold Thus, the hand operated tool according to the invention can be used with all commercially available drinking bottles, regardless of capacity. The size of the device according to the invention and the materials used can be varied according to the requirements of any application.
