【考案の詳細な説明】
本考案は易開封性密封容器に係り、詳しくは密封蓋体の
一部を開裂可能とすることにより開封を容易になした密
封容器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an easily openable sealed container, and more particularly to a sealed container that can be opened easily by making a part of the sealing lid cleavable.
従来よりプリン、生クリーム、アイスクリーム、飲料等
の食品類の包装容器として、容器本体に密着した蓋体を
剥離して内容物を取り出し得るようにした易開封性密封
容器が利用されている。BACKGROUND ART Conventionally, easy-to-open sealed containers have been used as packaging containers for foods such as pudding, fresh cream, ice cream, and beverages, in which the contents can be taken out by peeling off a lid that is tightly attached to the container body.
この種の易開封性容器は、容器本体の上縁外周に設けら
れたフランジ部の上面に、蓋体を通常ヒートシール等に
より剥離可能な状態で密着接着して密封されるが、輸送
取扱時には剥離しないで、しかも使用時には容易に剥離
できるような相反する要求を満す蓋体接着を行うことは
甚だ困難であった。This type of easy-open container is sealed by adhering the lid in a removable manner, usually by heat sealing, to the top surface of the flange provided on the outer periphery of the upper edge of the container body. It has been extremely difficult to bond a lid that satisfies the contradictory requirements of not peeling off and yet being easily peelable during use.
したがって、充分な密封接着性を得るために、フランジ
面を比較的に広い面積とするとともに、蓋体の一部を引
刺し用舌片を設けるなど、種々の提案がなされているが
、従来のものは何れも蓋体全部をフランジ面から剥離す
ることを目的とするものであり、剥離による易開封性と
するには必然的にシール強度を成る程度犠牲にせざるを
得なかった。Therefore, in order to obtain sufficient sealing adhesion, various proposals have been made, such as making the flange surface relatively wide and providing a part of the lid with a tongue piece for pulling. The purpose of all of these is to peel off the entire lid from the flange surface, and in order to make the seal easier to open by peeling, the sealing strength must necessarily be sacrificed to a certain extent.
本考案は上記の問題点ご解消することを目的とするもの
であって、容器のフランジ部と蓋体とのシール強度は充
分となすとともに、開封は蓋体の一部を引張りによる剥
離開裂により容易に行い得るようになして、密封強度と
易開封性の両要求条件を満足せしめる密封容器を提供す
るものである。The purpose of this invention is to solve the above-mentioned problems.The sealing strength between the flange of the container and the lid is sufficient, and the lid can be opened by peeling and tearing by pulling a part of the lid. It is an object of the present invention to provide a sealed container that can be easily sealed and satisfies both the requirements of sealing strength and ease of opening.
以下、図面に示す実施例により説明する。The embodiments shown in the drawings will be explained below.

ることが好ましい。Reference numeral 4 denotes a lid, which covers the upper surface of the container body 1 and seals the inside of the container body 1 by heat sealing or adhesive sealing on the entire surface of the flange portion 2. It is preferable that the tip of the tongue piece 3' corresponding to the tongue piece 3 has a sealing strength weaker than other parts or is not sealed so that initial peeling is facilitated.

されるのである。Since the present invention has the above-mentioned configuration, after filling the container body 1 with the contents, the lid 4 is strongly adhesively sealed at the flange portion 2 of the container body 1 as shown by the dashed hatching. It is a sealed container, and when using it, the tongue piece 3 of the lid body 4
' is pulled off from the tongue piece 3 of the container body 1, and when the peeling of both tongue pieces 3, 3' reaches the steps 6, 6, the adhesive width between the two suddenly expands, and the adhesive force is greater than the peeling force. On the other hand,
The peeling force applied to the tongue piece 3' is greater than the peeling strength of the lid 4, and the lid 4 forms a tear edge shown at 6' in FIG. is formed and unsealed.

好ましく用いられる。The lid body 4 can be made of metal foil such as aluminum with a thickness of about 40μ, which has been commonly used in the past, or thinner aluminum foil and paper.
Laminated composite materials of aluminum foil and plastic film or different types of plastic films are used, but heat-sealable composite materials include polyester film 7, paper 8, and aluminum foil 9 as shown in Figure 4.
A laminated material consisting of a heat adhesive layer 10 such as polyethylene or the like is preferably used.

ものである。As explained above, according to the present invention, the upper edge flange portion 2 of the container body 1 and the lid body 4 are strongly adhesively sealed, and the tongue pieces 3, 3' and the wide width of the base portions 6, 6 are formed. Easy opening is achieved by tearing and peeling the lid 4 due to the difference between the adhesive strength at the projecting edges 5, 5 and the tear strength of the lid 4 itself, and the opening for taking out the contents can be opened without requiring excessive force. This improves practical convenience in that it can be easily formed.
