Description

  The present invention accommodates stored items such as instant foods in individual containers such as bowls and cups, and is used for sealed packaging by heat bonding to the opening edge of the container, pouring hot water when eating, predetermined The present invention relates to a lid material for a container with a hot water cut-off function provided with a hot water cut-off hole (mouth) for quickly draining (hot water draining) after a lapse of time. Examples of stored items include instant foods such as raw noodles, fried noodles, spaghetti, and their seasonings or ingredients.

  Conventionally, plastic containers made of expanded polystyrene or the like are used for containers that contain stored items such as instant foods that are stored in bowl-shaped or cup-shaped containers. Many are used.

  The container is used to store items such as instant foods, hermetically packaged ingredients and sauces, seasonings, etc., and a plastic molded lid with a cut formed as a hot water cut hole is fitted or sealed. Thus, the opening of the container is sealed.

  Furthermore, the thing of the structure which carried out shrink packaging of the whole container by which the opening part was sealed using a shrink film etc. is known.

  When eating stored items such as instant food stored in a bowl or cup-shaped container, take out the seasoning stored in the container together with stored items such as instant food. , Pour hot water.

  Then, after a predetermined time has elapsed, as shown in FIG. 10 or FIG. 11, the container (101) is inclined, and hot water is drained from the hot water outlet (104) applied to the lid member (102). .

  When performing the hot water cutting, a container in which the plastic molding lid is only fitted to the container opening may cause the lid to come off from the container, or the hot water and stored items may leak from the gap between the lid and the container, resulting in burns. is there.

  For this reason, a lid material with a hot water draining function such as an instant food container as shown in FIG. 7 (a) or (b) is known as a container for draining hot water while the lid material is adhered to the container. As shown in FIG. 7B, the lid member (110) is sealed to the flange portion (162) of the container (109) main body.

  The lid member (110) has an aluminum foil (107) and a sealant layer (108) laminated on the back surface of the top sheet (106). And the through-hole (105) for hot water cutting is drilled in the surface sheet of the lid | cover material (110).

  In the lid member (110), dust or dirt accumulates in the hole (105) or breaks against the pierce hole (105) unintentionally during transportation.

  In addition, when hot water is cut off, the aluminum foil (107) and the sealant layer (108) are used by using chopsticks or the like in the piercing hole (105) formed on the upper surface of the lid (110) sealed in the container (109). Is broken through.

(1) Prior art 1
In addition, as a lid material with hot water holes for instant food containers, the hot water holes are not exposed during transportation, and the surface sheet for exposing the hot water holes is light and stable during use. A cover material with a hole (for example, refer to Patent Document 1) is known.

  As shown in FIG. 8 (a) or (b), the composite sheet (121) and the top sheet (122) have an easily peelable region ( e) and an adhesive region (d), which are laminated and adhered to each other. And the perforation (125) which can be cut | disconnected along the boundary line of an easily peelable area | region (e) and an adhesion | attachment area | region (d) is given.

  Further, in place of the detachable perforation (125), a foldable folding line (not shown) is provided. And the surface sheet (122) of an easily peelable area | region (e) can be peeled, and the peeled surface sheet (122) part can be bend | folded upwards and can be drained.

  Moreover, when peeling off the topsheet (122) in the easy-peeling region (e), the composite sheet (121) is pulled by pulling up the topsheet pull tab (136) connected to the easy-peeling region (e). One to several hot water cut holes (124) are formed on the surface.

(2) Prior art 2
Also, an instant food that can accurately and accurately separate the surface sheet on the side of the easy peeling area along the partition boundary portion between the easy peeling area and the other adhesive area without providing a separation line by perforation. A lid member with a hot water hole for a container (see, for example, Patent Document 2) is also known.

  As shown in FIG. 9 (a) or 9 (b), the lid 130 with a hot water cut hole of the instant food container is coated with an easy-release agent in a predetermined shape region of the composite sheet (132) and the top sheet (131). By doing so, the easy peeling layer (135) is formed. And the easily peelable area | region (C) which has an easily peelable layer (135), and the other adhesion | attachment area | region (D) are provided.

  Moreover, the easy peeling area | region (C) and the adhesion area | region (D) other than that are divided along the linear boundary line (133). And they are laminated and bonded together.
