The technical scheme is as follows: a large-mouth food packaging can which can still be sealed after being opened for many times comprises a can body with an opening at the top end and a can cover connected to the opening part in an openable and closable manner through a thread structure; the method is characterized in that: the inner end face of the tank cover is provided with a ring of annular clamping ring protruding out of the end face, the annular clamping ring can be inserted into the tank from the opening when the tank cover is closed, and is embedded with the inner wall surface of the tank body and is in compression fit with the inner wall surface while the tank cover is screwed, so that air circulation inside and outside the tank body is isolated, and sealing is achieved.
Description
Technical Field
The utility model relates to a food packaging tin, in particular to a large-opening food packaging tin which still keeps a sealing state after being opened for a plurality of times.
Background
In the domestic two-vigorous market, the large-mouth canned food made of various transparent materials is favored by wide-light consumers due to the characteristic that the content of the large-mouth canned food is clearly visible. However, most of the prior large-mouth food cans only keep a sealed state before opening the cap, but have no sealing measures after the use of opening the cap, so that the taste of the food remained in the cans is influenced when the food cans are continuously eaten. For example, after a part of canned pecan nuts which are popular with people is eaten after being opened, although the can cover is tightly covered, the remaining nuts in the can are easy to be affected with damp, smell and even deteriorate due to insufficient sealing degree of the can cover.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned background art not enough, provide a big mouthful of food package jar that uncaps many times and still seal, should pack jar and should be able to continue to keep the encapsulated situation of cover and jar body after uncapping to keep the quality and the flavor of jar interior food.
The utility model provides a following technical scheme:
a large-mouth food packaging can which can still be sealed after being opened for many times comprises a can body with an opening at the top end and a can cover connected to the opening part in an openable and closable manner through a thread structure; the method is characterized in that: the inner end face of the tank cover is provided with a ring of annular clamping ring protruding out of the end face, the annular clamping ring can be inserted into the tank from the opening when the tank cover is closed, and is embedded with the inner wall surface of the tank body and is in compression fit with the inner wall surface while the tank cover is screwed, so that air circulation inside and outside the tank body is isolated, and sealing is achieved.
The outer circumference of the annular clamping ring is provided with a conical sealing embedding surface with a small lower part and a big upper part.
The height of the annular clamping ring protruding out of the end face is 3-10 mm.
The outer circumference of the can cover is provided with an anti-slip strip which is convenient to hold.
The utility model has the advantages that:
because the annular clamping ring matched with the inner wall of the tank body is prepared on the inner end surface of the tank cover. After a part of food is eaten after the cover is opened and the can cover is screwed down again, the space in the can still be effectively isolated from the outside, and the rest part of food can still keep the original quality and flavor in the can, so that the food is not easy to be affected with damp and go bad; and after the annular clamping ring is additionally arranged, the strength of the tank cover is enhanced, the tank cover is not easy to deform, and the sealing effect in the closing process is also improved. In addition, after the anti-slip strip is arranged outside the can cover, the can be opened and closed more easily, and the can cover is popular with consumers.

Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The large-mouth food packaging tin which is shown in the attached drawing and still sealed after being opened for many times comprises a tin body 1 with an opening at the top end and a tin cover 2 which can be opened and closed to cover the opening part through a thread structure (consisting of an external thread at the top of the tin body and an internal thread 2-1 which is positioned on the inner circumferential surface of the tin cover and is matched with the external thread).
The structure is similar to the existing large-mouth food packaging tin.
A disposable sealed film cover (the film cover is omitted in the figure) is adhered to the opening part of the large-mouth food packaging tin; therefore, the packaged food can be isolated from the outside and is not affected by the outside air. However, after the cover is opened, the film cover is torn off, and a sealing structure is lacked between the can cover and the can body; although the antistaling agent for oxygen absorption is generally placed in the tank, the antistaling agent can be maintained only for a short time; the fresh-keeping can not be carried out for a long time.
The utility model discloses the improvement of doing for this reason is that the interior terminal surface at the macrostoma food packaging jar cover is prepared with the annular rand 2-1 that the round salient is in the terminal surface, and the annular rand can be followed when the lid closes the cover in the opening inserts jar to with the inner wall surface gomphosis of the jar body and with inner wall surface compressed tightly the cooperation when the lid is covered tightly, thereby isolated jar internal outside circulation of air, realize reliably sealing.
Furthermore, the outer circumferential surface of the annular retainer ring is provided with a conical sealing and embedding surface 2-1-1 with a small lower part and a big upper part; when the can cover is closed, the sealing embedded surface can guide the insertion of the annular clamping ring and is beneficial to the embedded sealing of the annular clamping ring and the inner wall of the can body.
The height of the annular clamping ring protruding out of the end face is 3-10mm, and the height can be specifically selected according to needs.
Further, the outer circumferential surface of the can cover is provided with a slip-proof strip 3 (which can be vertically arranged as shown in the figure) for convenient holding; the anti-slip strips can be distributed on the whole outer circumferential surface of the tank cover according to requirements, or regularly grouped (a plurality of strips are distributed on partial parts of the outer circumferential surface); the user can feel easy and convenient when opening the can or screwing the can cover.
The tank body and the tank cover are preferably formed by injection molding of PE materials.
The principle of the utility model is that: when the internal thread of the tank cover is matched and screwed with the external thread at the top of the tank body, the annular clamping ring at the inner end face of the tank cover is inserted into the tank body and is embedded and sealed with the inner wall of the tank body, so that the space in the tank body is isolated from the outside, and the aim of effective sealing is fulfilled.
