Abstract

(57) [Summary] [Structure] A plastic can comprising two or more fixing plates 2 that can fix the plastic can 1 from above and below, and a columnar body 3 that holds the fixing plate 2 at the same interval as the height of the plastic can 1. Fixture for heat sterilization. [Effect] By setting the plastic can on the heat sterilization fixture and sterilizing by boiling, the bottom of the plastic can will not be deformed such as expansion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat sterilization fixture used for sterilizing a plastic can, which is filled with food and double-wrapped, with boiling.

[0002]

[Prior art]

 Traditionally, plastic cans whose main body is made of plastic are filled with foods such as fruits and honey beans, and the plastic cans that have finished the winding process are individually passed through a boil sterilization line for heat sterilization.

[0003]

[Problems to be solved by the device]

 Even if you try to fill the plastic can filled with the above food without any gaps, the head space is generated by the heat of boiling sterilization because the spillage of the liquid in the winding process and the gas emitted from the pulp of the mandarin oranges during sterilization of the boil will cause headspace. The gas in the space expands, causing the expansion and deformation of the bottom of the can.

[0004]

[Means for Solving the Problems]

 As a result of various studies to solve the above problems, the present inventor has found that the deformation can be prevented only by fixing the top and bottom of the plastic can, and arrived at the present invention. The gist of the invention is to fix the plastic can from above and below. A fixture for heat sterilization of a plastic can, which comprises two or more possible fixing plates and a columnar body that holds the fixing plates at the same intervals as the height of the plastic can.

The plastic can can be set in the fixing device for heat sterilization of the present invention, and the bottom and the upper part of the plastic can can be fixed by the fixing plate to sterilize by boiling to prevent deformation.

Hereinafter, the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the heat sterilization fixture of the present invention, and FIG. 2 is a side view of a cross section of the heat sterilization fixture of FIG. 1 with a plastic can set.

The present invention, as shown in FIGS. 1 and 2, includes two or more fixing plates 2 that can fix a plastic can 1 from above and below, and a pillar that holds the fixing plate 2 at the same interval as the height of the plastic can 1. It is a fixing tool for heat sterilization of a plastic can, which is made of the shape 3.

The fixing plates 2 are provided in a multi-tiered shelf shape, and each fixing plate 2 is provided with a recess 21 having a shape fitting the bottom portion of the plastic can 1 on the upper surface thereof so that the plastic can 1 can be easily positioned. The plastic can 1 is prevented from slipping during boiling sterilization.

One of the pillars 3 is a vertical plate 31, one end of the fixed plate 2 is attached by a hinge 4, and the other is a bolt 32 as shown in FIG. The bolt holes 22 are provided to fix the fixed plate 2 in place, and the upper and lower parts that hold the fixing plate 2 at the same interval as the height of the plastic can 1 are fixed.

The force at the time of fixing the plastic can 1 is more than a force that does not cause a space in which the plastic can 1 expands during sterilization by boiling and is less than the buckling strength of the plastic can 1 at the boiling sterilization temperature. The force may be set, and the material is preferably metal such as aluminum. Hereinafter, the present invention will be described with reference to examples.

[0011]

【Example】

 As a plastic can 1, a polypropylene type C-6 size one was prepared, and this was filled with 140 g of mandarin orange solid content plus 120 g of liquid content, and the aluminum lid was double wound.

When boil sterilization was carried out by setting the apparatus of FIG. 1 in the state of FIG. 2 and heating at a boiling temperature of 85 ° C. for 20 minutes, the maximum headspace of the plastic can was about 10 cc. No deformation of the bottom of the plastic can was observed. Further, there was no deformation such as expansion of the plastic can body in the radial direction.

[0013]

[Effect of device]

 The present invention is a fixing tool for heat sterilization of a plastic can, which comprises two or more fixing plates capable of fixing the plastic can from above and below, and a columnar body which holds the fixing plates at the same interval as the height of the plastic can. By setting the can on the heat sterilization fixture and sterilizing it by boiling, the bottom of the plastic can will not be deformed by expansion or the like.
