Abstract

PROBLEM TO BE SOLVED: A conventional lid of a cup container has a problem that once it is opened, it cannot be resealed with the same degree of sealing as before opening, or it takes a lot of time and labor. This is because the opening of the cup container was heat sealed or adhesively sealed with a sheet-like lid. A flange portion 33 at an end of an opening portion 32 of a cup container body 31 is fixedly mounted by a flange presser cap body 11, and the cup container body 31 and the opening portion 32 are bonded by pressure bonding with the opening sealing lid body 21. The sealing lid was made. Thereby, the lid body of the cup container can be repeatedly opened and sealed with a high degree of resealability. [Selection] Figure 1

Description

  The present invention includes a flange-pressing cylindrical cap main body 11 for pressing from the flange portion 33 outer peripheral upper surface portion 35 projecting outward at the end of the opening 32 of the cup container main body 31 and the flange portion 33 inner peripheral lower surface portion 34. The present invention relates to a lid for a flanged cup container comprising a flange-pressing cylindrical cap by joining with an opening-sealing columnar plate lid body 21 for holding, and an opening-sealing columnar plate lid.

  Conventionally, a sheet-like lid that seals the cup container and the opening of the cup container is known. This sheet-like lid is adhesively sealed to a flange protruding outward at the opening end of the cup container, and the opening of the cup container and the sheet-like lid are adhered with an adhesive resin by heat sealing treatment. It consists of

However, the conventional sheet-like lid described above has a problem that once it is opened, it is very difficult to reseal and cannot be resealed with the same degree of sealing before opening. . In addition, even if the opening of the cup container is temporarily sealed with Saran wrap or Kure wrap, the sealing force before opening cannot be maintained, and there is a problem of early deterioration of the contents of the cup container and scattering to the outside. .
Regarding the above problems, the object of the present invention is to increase the reproducibility of the sealing seal strength at the opening of the cup container, to enable hermetic sealing even when repeatedly opened and sealed, to maintain the quality of the contents of the cup container, This is to ensure safe storage.

And in order to solve the above-mentioned subject, this invention adapts to the inner periphery circumference caliber of the flange part 33 outer peripheral upper surface part 35 which protrudes to the outer side in the opening part 32 end of the cup container main body 31, and fixes the said flange 33 A flat packing comprising a cylindrical cap main body 11 for holding a flange having a through-hole 13 and serving as a sealing portion for the opening 32 of the cup container main body 31 at a contact portion for crimping and sealing the inner peripheral lower surface portion 34 of the flange portion 33. A cylindrical plate lid body 21 for sealing an opening having an outer peripheral top plate surface. The cap body 11 and the lid body 21 are individually and separately divided, and the flange 33 An outer peripheral upper surface portion 35 and an inner peripheral lower surface portion 34 are sandwiched between the cap main body 11 and the lid main body 21 and are fixed by crimping, and the opening 32 of the cup container main body 31 and the cylindrical flat lid body for sealing the opening. The flat packing portion 22 at the outer peripheral top plate surface 27 of 1 and pressed, sealed, has become to seal.
A wall surface for hooking the outer circumferential edge portion of the through-hole 13 to the diameter of the outer circumferential edge of the flange portion 33 and pressing and fixing the outer circumferential upper surface portion 35 of the flange portion 33 with a cylindrical inner circumferential ceiling wall surface 14; The cylindrical inner peripheral side wall surface 14 is provided with the flange-pressing cylindrical cap main body 11 having the female screw portion 12, and the inner peripheral lower surface portion 34 of the flange portion 33 is softer than the lower surface portion of the flange portion 33. The cylindrical packing plate 22 has a flat packing portion 22 in the form of a circumferential belt, and has a male screw portion 23 that fits the female screw portion 12 on the outer peripheral side wall surface 26 of the cylindrical flat plate. The opening bottom sealing cylindrical plate lid body 21 having a handle 24 which is an auxiliary projection for screwing the male screw portion 23 and the female screw portion 12 is provided on the outer peripheral bottom surface 25 of At flange 33 Fixed flange, the flange portion 33 is fixed with the flange-pressing cylindrical cap, the cup container is sealed with the opening-sealing columnar flat plate lid, and the flange portion 33 is sealed. Items are to be sealed and stored.
At least a part overlaps the outer edge portion of the flange portion 33 in plan view of the outer peripheral upper surface portion 35 of the flange portion 33 and in plan view of the cylindrical inner peripheral top wall surface 14 and is fixed by crimping. The flange-clamping cylindrical cap body made of a polyethylene material having a cylindrical inner periphery in which the female screw portion 12 is provided on the wall surface 15 and the through-hole 13 is formed on the inner peripheral ceiling wall surface 14. 11 and at least a part of the flange portion 33 in a plan view of the inner peripheral lower surface portion 34 and a plan view of the outer peripheral top plate surface 27 overlaps an outer edge portion of the flange portion 33 in the plan view of the inner peripheral lower surface portion 34, and is fixed by crimping. The outer peripheral side wall surface 26 of the cylindrical plate has the male screw portion 23 that fits the female screw portion 12, and the outer peripheral bottom surface 25 of the cylindrical plate has the handle 24 that is a circular projection, In the outer peripheral top plate surface 27 of the cylindrical flat plate, the opening sealing made of a polyethylene material having the flat packing portion 22 formed of a silicon material, a nylon material, a rubber material, or a foamed polystyrene material is used. The lid body is made of a softer material than the cup container body 31 made of glass, polypropylene, aluminum, or stainless steel.

  As described above, the present invention provides a cup container body by sandwiching and pressing the flange portion 33 between the upper surface portion and the lower surface portion of the flange pressing cylindrical cap body 11 and the opening sealing columnar plate lid body 21. Even if the opening 32 of the opening 31 is opened once, it can be resealed again without changing the sealing force, and the sealing degree and the sealing performance can be reproduced and kept equal to those before opening. Therefore, the contents of the cup container body 31 can be taken in and out by repeatedly opening and sealing the opening 32. Moreover, the cylindrical cap body 11 for holding the flange and the columnar plate lid body 21 for sealing the opening can be divided into individual bodies, so that they can be individually replaced and replaced, and the female screw portion 12 and the male screw. Adjustment of the degree of pressure-bonding between the lid body 21 and the opening 32 by adjusting the screwing condition of the portion 23 enables fine adjustment of the sealing degree, and for handling by degassing, gas expansion and condensation in the cup container body 31 The internal pressure can be adjusted. Further, compared to the case where the flange portion 33 of the opening portion 32 is heat-sealed and sealed with a sheet-like lid body, the flange portion at the end of the opening portion 32 is attached to the cylindrical plate lid body 21 for sealing the opening portion. By providing the flat packing portion 22 made of a material softer than the portion 33 material, it becomes possible to further increase the efficiency of the sealing degree by elastic pressure bonding between the opening portion 32 of the cup container body 31 and the lid body, and the cup container body The quality of the contents of 31 can be maintained and stored in sealed packaging.
