JPH0431227A - Opening/closing device for container lid - Google Patents

Abstract

PURPOSE:To make an asured sealing effect possible by a simple structure, which does not require turning of an opening/closing ring by a method wherein after a lid has turned to the vicinity of an opening of a container main body by a hinge, the lid is moved by a sliding mechanism to a position to meet the opening of the container, and an opening/closing ring split in two and a packing box simultaneously fasten the peripheral edge of the lid such as pinching the peripheral edge of the lid. CONSTITUTION:An opening/closing ring 10 is vertically split in two, and one opening/closing ring 10a is attached to a packing box 11 at the open peripheral edge of a container main body 4, and the other opening/closing ring 10b is attached to the peripheral edge of a lid 1. The lid 1 is supported by a hinge 2 and bracket 3, and at the same time, it is slidably provided by the bracket 3. Therefore, by moving the lid 1 to the vicinity of the opening of the container main body 4 by the hinge 2, and sliding the lid 1 to a position to meet the opening of the container main body 4 by a manual or automatic sliding mechanism 5, the peripheral edge of the lid 1 is pinched between the opening/closing ring 10 and the packing box 11 to seal the container.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lid opening/closing device for use in retort devices and other containers.

2. Description of the Related Art A conventional lid opening/closing device for a retort apparatus has a structure as shown in FIGS. 7 to 9, for example.

Reference numeral 15 denotes a lid, which is disposed so as to be tightly crimped to the opening of a container body 16 of a retort device, etc., and is connected to a hinge portion 17 and a bracket 1.
8, and is provided so that it can be opened and closed manually.

Reference numeral 19 denotes an opening/closing ring, which is rotatably provided on the outer periphery of the lid 15, either manually or by a drive unit 20 such as an air cylinder, and has a vise part 21 on the inner periphery. Reference numeral 22 denotes an engaging portion provided on the periphery of the lid, and the opening/closing ring 19 is rotated while the engaging portion 22 is aligned with the engaging portion 23 provided on the periphery of the container body 16, and both engaging portions 22 are aligned with each other.
．． 24 indicates a sealing gasket which is designed to sandwich 23 and seal the lid 15.

Problems to be Solved by the Invention However, in the above configuration, in order to tightly press the lid 15 to the opening of the container body 16 of a retort device, it is necessary to close the lid 15 and close the opening/closing ring 19 on the container body 16 side. Therefore, the rotating mechanism for the opening/closing ring 19 and the vise part are required, making the structure complicated.

An object of the present invention is to provide a lid that can be easily sealed by sandwiching the lid edge by moving the lid in a direction that matches the opening of the container body without requiring the above-mentioned complicated structure. The aim is to provide a switchgear for this purpose.

Means for Solving the Problems In order to achieve the above object, the present invention includes a lid attached to the opening of the container main body so as to be openable and closable via a hinge portion and a bracket, and a lid attached to the container between the lid and the bracket. A sliding mechanism that can be moved manually or automatically in a direction that matches the opening of the main body, and an opening/closing ring (a ) and (b)
and a backing box provided around the opening of the container main body, one of the two-split opening/closing rings (a) or (b) is attached to the backing box, and the other opening/closing ring is attached to the backing box. (b) or (a) is attached to the lid, the lid is supported by a bracket and is provided so as to be slidable manually or automatically in a direction that matches the opening of the container body by a sliding mechanism; The container lid opening/closing device is arranged such that when the lid moves and matches the opening of the container body, the peripheral edge of the lid is sandwiched between the opening/closing ring and the backing box and sealed.

Function: As described above, the lid is supported by the hinge portion and the bracket, and is slidably provided by the bracket.

Therefore, by moving the lid near the opening of the container body via the hinge and manually or automatically sliding it to a position that matches the opening of the container body, the peripheral edge of the lid can be moved between the opening/closing ring and the backing box. It is sandwiched between the two and can be sealed.

EXAMPLE Hereinafter, a lid opening/closing device as an example will be described with reference to the drawings.

Reference numeral 1 denotes a lid, which is supported via a hinge part 2 and a bracket 3, and is attached so that the opening of the container body 4 can be opened and closed. A sliding mechanism 5 is provided between the lid 1 and the bracket 3.

1 to 4 show an example of a sliding mechanism in which the lid 1 is manually moved horizontally from the left side to the right side.゛This sliding mechanism is not limited to the above example, but can also be used as a lid for high-temperature, high-pressure applications such as retort devices, and by providing a safety device, it is also possible to move the lid vertically or in an inclined direction. In short, at the time of rotation by the hinge portion 2, the lid 1 is moved near the opening of the container body 4, and is moved by the sliding mechanism 5 in a direction that coincides with the opening.

In Figures 1 to 4, 6 is a handle, 7 is a gear,
Numeral 8 is a rack, and 9 is a sliding portion that fits in the concave and convex portions to ensure safety. The above 6 to 9 constitute the sliding mechanism 5.

10 is an opening/closing ring, which is vertically divided into two to form 10a and lob. One opening/closing ring IOa is connected to the container body 4.
attached to the backing box 11 at the opening periphery of the
The other opening/closing ring IOb is attached to the periphery of the lid l.

In Figure 1, the lid l has an opening/closing ring 10 and a backing box 1.
Fig. 2 shows a state in which the lid has been moved and opened.

Incidentally, the direction in which the opening/closing ring IO is divided into two may be a horizontal direction or an inclined direction in relation to the above-mentioned sliding mechanism 5.

Figure 5 is an enlarged view showing the state of the seal, with the opening/closing ring lO
The periphery of the lid 1 is held between the backing box 11 and the backing box 11,
The backing 12 is shown in a state in which air pressure is applied through the air holes 13 and the backing 12 is completely crimped.

FIG. 6 shows another embodiment of the lid sliding mechanism 5, in which an air cylinder 14 is used instead of manually.

Effects of the Invention Since the present invention adopts the above-described configuration, the lid is supported by the hinge portion and the bracket so as to be rotatable and to open and close the opening of the container body. A sliding mechanism is provided between the lid and the bracket, so that after the lid is rotated by the hinge and positioned close to the opening of the container body, the sliding mechanism moves it to a position where it matches the opening. At the same time, the two-split opening/closing ring and the backing box engage with each other so as to sandwich the peripheral edge of the lid, allowing sealing by the backing.

As mentioned above, sealing is possible automatically by moving the lid, and there is no need to rotate the opening/closing ring as in the conventional case, so the structure is simple, the sealing effect is reliable, and there is no problem with safety. , it was possible to provide a lid opening/closing device that can be configured extremely economically.

The sliding direction of the bracket and the lid is not limited to the horizontal direction, but can also be moved vertically or tilted depending on the surrounding environment and space issues, and can be used in a wide range of applications as a lid opening/closing device.
