LT5210B - Device for forcing out content of tube - Google Patents

Abstract

The invention relates to household appliances. The device for forcing out content of tube has a housing and an axle (3) with a longitudinal gap (3a) and a handle (4), a ratchet, a plane spring (5). The housing is made of two plates (1, 2) with two lugs (1a, 1b, 2a, 2b) on each side thereof. When the handle (4) is rotated, the tube is wound on the axle discharging the content. Discharging the content of tube may be performed by pressing and releasing the upper parts of the housing plates (1, 2).

Description

The invention relates to household appliances and is intended for extraction of semi-liquid contents from tubes or elastic bags.

A number of hand-held devices are known for squeezing paste from tubes.

There is a known device for extruding a toothpaste from a tube having a housing having three rotatable spindles, the first of which has a longitudinal slot and a handle, and a small gap between the other two, placed in front of the first. By inserting into the longitudinal slot of the first roll, the flanged end of the tube and rotating the knob, the tube sheath is wound on the first roll and its contents pressed (pushed) toward the outlet by the other two adjacent rolls (see US 2548535).

The disadvantage of this device is that the first roller on which the tube is wound has no locking and can rotate. This device may only be used when attached to a fixed support.

A device for extruding a paste from a tube is known, having a housing (plate) having two perpendicular lugs on its sides with coaxial apertures into which a shaft with a longitudinal slot is inserted. The shaft has a handle and comes with a pressed spring support (see patent RU 20736290).

The disadvantage of this device, as mentioned above, is that it can only be used when attached to a fixed support.

There is known a device for squeezing the contents of a tube, having a shaft with a longitudinal slot for fixing the flattened end of the tube, a ratchet mechanism for turning and locking the shaft, a spring-clamping two knob-levers and a housing (see patent RU2114034 Cl).

The disadvantage of this device is the complicated design due to the use of two folding levers - the handle system.

The object of the present invention is to provide a compact and simple device for the extraction of semi-liquid (viscous) contents from a tube or an elastic bag.

This object is achieved by the device for extruding the contents of the tube having a shaft with a longitudinal slot and a handle, a ratchet mechanism with a flat spring and a housing consisting of two plates having two perpendicular tabs with coaxial apertures on each side; and a hollow shaft embedded therein, and the ratchet mechanism comprises a flat annular annular casing formed on one side of the housing, having a circular shaft handle, with radial teeth pressed against the inside, pressed against the inner surface thereof.

To facilitate the achievement of the stated purpose, some of the essential features of the device are specified as follows:

- the flat spring is fixed to a single plate of the housing;

- the other casing plate has a retaining wall;

- notches in a flat spring;

- the radial teeth of the ear ring rings are pressed against the handle by a resilient element attached to the handle and a pin inserted into the longitudinal slot of the shaft and capable of sliding therein;

- spring mounted between housing plates;

- a rotary nozzle mounted in the hole at the free end of the shaft;

- the radial teeth of the ear and shaft handle have an asymmetrical profile;

- The radial teeth of the shaft handle are segmented and made of elastic material.

BRIEF DESCRIPTION OF THE INVENTION

- FIG. 1 is a top plan view of the device;

Figure 2 is a side elevational view of the device;

Figure 3 is a profile of the radial teeth profile of the ratchet mechanism of the device.

The device consists of the following main parts: two body plates 1, 2, a shaft 3 with a handle 4, a flat spring 5, a resilient element 6, a nozzle 7 and a spring 8. The body plate 1 has two perpendicular lugs lb, lb , 2b. Flat spring 5 made with notches 5a and attached to housing plate 1. Other housing plate 2 has retaining wall

9. The shaft 3 is made hollow and provides a longitudinal slot 3a. The tabs 1a and 2a have flat annular spaces 10, 11 on the outside of the radial teeth 10a and 11a, respectively. The lug la has an annular support 13. The radial teeth 4a are made on the inside of the handle 4. The tabs la and 2a, as well as the tabs 1b and 2b, are identified by a shaft inserted into their apertures such that the radial teeth 10a and 11a of the pads 10, 11 are pressed against the radial teeth 4a of the handle 4. The clamping is carried out by a resilient element 6 attached to the handle 4 and the pin 12, which is inserted into the longitudinal slot 3a of the shaft 3 and rests on the inner part 13 of the annular support. The pin 12 can slide in the longitudinal slot 3a of the shaft 3. A hole 7 is inserted into the hole 3 of the shaft 3 at its free end so that it can rotate about its axis in the hole 3 of the shaft. A spring 8 rests between the housing plates 1 and 2 to hold them in their original fixed position. The profile of the radial teeth 10a and 4a is shown in Fig. 3, the profile of the radial teeth 11a being analogous to that of 10a. Handles 4 The radial teeth 4a are segmented and made of an elastic material such as plastic. The dotted line in Fig. 2 shows the tube 14 inserted in the device.

The device works this way.

The starting position of the device is as follows: by means of the elastic element 6, the sites 10 and 11 are pressed against the handle 4, their radial teeth 10a, 11a being engaged with the handle radial teeth 4a. The handle 4 can only be turned in one direction with respect to the housing plates 1, 2, clockwise, and the handle 4 together with the shaft 3 cannot be rotated in the opposite direction, as opposed to the radial teeth 10a, 11a and 4a. Alternatively, the knob 4 can be rotated by periodically pinching and releasing the tops of the housing plates 1, 2 with your fingers. To freely rotate the handle 4 with the shaft 3, the nozzle 7 must be pressed. In this case, the shaft 3 together with the handle 4 is disengaged from the discs 10, 11 and the radial teeth 10a, 11a come out of engagement with the radial teeth 4a.

The tube 14 is inserted into the device as follows. The flattened end of the tube 14 is inserted into the longitudinal slot 3a of the shaft 3 and, by turning the handle 4 in a clockwise direction, the tube 14 is locked in the device. There are two ways to extrude the contents of the tube: by turning the knob 4 or by squeezing and releasing the tops of the housing plates 1, 2. As the spindle 3 turns, the shell 14 of the tube is wound on it, and the flat spring 5 on one side and the retaining wall 9 on the other side push the contents of the tube towards the outlet.

The tube 14 is withdrawn from the device by pressing the tip 7.

The device can also be used to squeeze the contents of elastic bags.

The proposed device has the following features:

- is compact;

- it can be used with one hand;

- convenient positioning of the device with the tube at the desired location;

- Easy to measure the amount of squeezed content

- its noise-free operation;

- Easy to clean.

The device can be used to squeeze toothpaste, shoe oil, glue, etc., as well as foods such as various pastes or dressings, squeezing cream from elastic tubes or bags.
